  • stamps is used herein and in the appended claims to mean roll dispensed articles, typically imprinted and perforated for separation, of the nature of a postage stamp, including such articles as trading stamps, tickets for theater and sporting events and the like.
  • the stamps are therefore pushed or pulled through the stamp-dispensing mechanism by the moving sprockets or engaging fingers. Often times this results in a tearing of the stamps along the perforations and in a jamming of the stamp strip in the dispenser. Additionally, variations in stamp length caused by changes in manufacturing standards and changes in humidity produce stamp-feeding problems in these machines.
  • the present invention employs a novel stamp drive apparatus which does not employ sprockets or fingers engaging the perforations between stamps, but rather employs a flexible drive member, such as a moving rubber belt, which engages the stamps across a substantial portion of their surface and carries the stamps along in an egress movement without the pushing or pulling action at concentrated areas of the stamp inherent in the prior art sprocket or finger drives.
  • This particular stamp drive apparatus permits ease of loading and threading the stamps through the dispenser since it is not necessary to align perforations with sprockets, fingers or the like, but it is only necessary to place the stamps into contact with the belt drive, the belt drive then simply threading and carrying the stamps along through the drive unit.

  • the stamp-dispensing system comprises three separate stamp dispenser units 11, 12 and 13, although less than or more than three dispenser units may be utilized.
  • a single main drive motor 14 and drive shaft 15 is provided having three separate drive wheels 16, 17 and 18 fixedly mounted thereon, each drive wheel being associated with a separate one of the three dispenser units (see FIG. 3).
  • Each dispenser unit has an associated pinch roller 19, 20 and 21 operable by solenoids 22, 23 and 24, respectively, for engaging the separate stamp dispenser units with the drive wheels.
  • a common stamp program board 25 is utilized to program each of the three dispenser units 11, 12 and 13 to dispense a particular number of stamps for one or another of the several coins that a coin acceptor 26 is capable of accepting.
  • the coin acceptor 26 includes well-known devices for accepting coins of three different values. but obviously other money acceptors may be used for accepting different coins or paper money if desired.
  • a typical binary counter 27 of the type employed in each of the dispenser units in this system is capable of counting up to 15 stamps and consists of four two-state flipflops. The flip-flops are connected in series and count in the typical binary sequence l-2-4-8. Each binary counter is manually preset by means of the program board 25 to count a selected number for each input signal from the coin acceptor 26.
  • the upper portion of the program board 25 is arranged in three columns, the 25-cent coin column, the 10-cent coin column, and the 5-cent coin column, and three rows, the 6- cent stamp row, the 5-cent stamp row, and the l-cent stamp row.
  • Each row has four pairs of jacks in each column and each pair of jacks controls one of the four flip-flop circuits in the associated binary counter.
  • the first pair of jacks 28 will set the binary counter 27 to count one, the second pair 29 to count two, the third pair 30 to count four, and the fourth pair 31 to count eight. Combinations of these jacks pairs will produce other counts; for example, strapping jack pairs 28 and 30 will set the binary counter 27 to count five, strapping jack pairs 28, 30 and 31 will set the count at 13 and strapping all fourjack pairs will set the count at 15.
  • the second pair of jacks 32 in the 25-cent coin column is strapped, the first pair of jacks 33 in the 10-cent coin column is strapped, and none of the pairs of jacks are strapped in the 5-cent coin column.
  • THis strapping sets the binary counter 34 so that, for a 25-cent coin, two 5- cent stamps will be dispensed; for a IO-cent coin one 5-cent stamp will be dispensed; and for a 5-cent coin no 5-cent stamps will be dispensed.
  • the binary counter 37 is thus set to count three l-cent stamps for a 25-cent coin, five 1- cent stamps for a IO-cent coin, and five l-cent stamps for a 5- cent coin.
  • the system has been preset so that for a 25-cent coin, two 6-cent stamps, two S-cent stamps and three l-cent stamps will be dispensed; for the l0-cent coin, five l-cent stamps and one 5-cent stamp will be dispensed; and for the 5-cent coin, five l-cent stamps will be dispensed.
  • the strapping across jacks may consist of electrically conducting pegs and each jack pair may be two conductors forming surfaces in a hole in a pegboard, the multiple peg holes being arranged in columns and rows in the program board.
  • the pegboard of electrical jacks is continuously made from conventional printed circuit board connectors in which conductor pins are removably inserted to connect opposite contact strips.
  • the coin acceptor 26 In operation, on receipt of a 25-cent coin, the coin acceptor 26 operates to close the circuit through switch 38 to the program board 25. Since jacks in all three rows in the 25-cent coin column have been strapped, all three stamp dispenser units 11, 12 and 13 are activated by closing ground through jack pair 29 to binary counter 27, through jack pair 32 to binary counter 34, and through jack pairs 35 and 36 to binary counter 37.
  • the binary counters operate to close a circuit to switch 39 which operates to close contacts 40 and complete a circuit to the drive motor control circuit 41.
  • the control circuit 41 operates to energize the main drive motor 14 to drive the wheels 16-18 and also operates switch 42 which closes a circuit through contacts 43 to the three coin solenoids 44, 45, and 46 coupled to the coin acceptor 26.
  • Solenoid 44 is associated with the 5-cent coin mechanism and solenoids 45 and 46 with the l0-cent and 25-cent coin mechanisms, respectively, in the coin acceptor 26. These solenoids operate to disable the coin acceptor 26 from accepting any additional coins, such additional coins being returned to the depositor until such time as the system finishes its current stamp dispensing cycle.
  • the binary counters 27, 34 and 37 also close a circuit to the delay circuits 47, 48, and 49 which, after a short delay, for example one-half to 1 second, operate to energize the one-shot multivibrator circuits 50, 51 and 52, respectively, which transmit an energizing signal through their associated amplifier circuits 53, 54 and 55, respectively, to the pinch roller solenoids 22, 23 and 24, respectively.
  • the pinch rollers 19-21 are moved into engagement with their associated drive wheels 16-18 and the three dispenser units ll, 12 and 13 are activated to commence dispensing stamps of all three values.
  • the to l-second delay provided by delay circuits 47-49 gives the drive motor 14 time to get up to nonnal speed before the pinch rollers engage the drive wheels.
  • the stamp counter circuit 56 associated with the stamp dispenser unit 11 and shown in more detail in FIG. 6 will be described, it being understood that the counter units 57 and 58 associated with the stamp dispenser units 12 and 13, respectively, operate in similar fashion to control the number of stamps being dispensed from their particular dispenser units.
  • the stamp counter unit 56 comprises a source of light 59 and an elongated cylindrical lens 60 which focuses the light into a strip-shaped beam, the light and lens being positioned on one side of the strip of stamps 61 such that the light beam extends transverse the stamp strip.
  • a pair of photocell detectors 62 and 63 are positioned on the other side of the strip of stamps 61 so as to intercept the light beam.
  • the positioning of a stamp between the light source 59 and the photo detectors 62, 63 will normally cut off or substantially attenuate the light impinging on the photodetectors. However, when the passage of the stamp aligns a line of perforations between adjacent stamps with the light beam, the light passes through the perforations and impinges upon the photo detectors 62, 63. The light impinging thereon will cause a current to flow to the pulse generator circuit 64 which operates to transmit a pulse through the amplifier 65 to the binary counter 27. At the same time, the pulse generator 64 sends a pulse to multivibrator circuit 66 which operates to produce a pulse to a totalizer counter circuit 67.
  • the totalizer counter 67 is utilized to count the total number of stamps dispensed from the dispenser 11 between refills. A single pulse is sent to the binary counter 27 for each stamp that passes out the egress opening of the stamp dispenser. Since the binary counter 27 has been set to count two by the strapping of the jack pair 29, it will operate after receipt of the second pulse from the stamp counter unit 56 to remove the energizing signal from the delay circuit 47 to therefore deenergize the pinch roller solenoid 22 and stop operation of the 6-cent stamp dispenser unit.
  • the S-cent stamps have been dispensed and the counter 34 has similarly operated in response to pulses from the optical counter 57 to count each 5-cent stamp as it passes out from the dispenser.
  • the binary counter 34 has also been set at the two count by the strapping of a jack pair 32 and it operates on the second pulse from the counter 57 to deenergize the pinch roller solenoid 23 and terminate the dispensing of the S-cent stamps.
  • the binary counter 37 has been set to count three by the strapping of jack pairs 35 and 36 and it operates to deenergize the pinch roller solenoid 24 after three pulses have been received from the 1- cent stamp counter 58.
  • counter 37 After the last binary counter, in this case counter 37, has operated to terminate the dispensing of stamps, it removes the energizing signal to switch 39 and the contacts 40 open to open the circuit to the motor control 41 and stop motor 14.
  • the drive motor control circuit 41 also operates to open the contacts at 43 and thus deenergize the coin control solenoids 44, 45 and 46 so that the coin acceptor 26 will be placed in a condition to accept the next coin deposited.
  • the motor control circuit 41 will energize the switch 42 to close contacts 43 and operate solenoids 44, 45 and 46 to prevent the coin acceptor 26 from accepting additional coins.
  • the stamp dispenser unit 12 will operate to dispense S-cent stamps and unit 13 will operate to dispense l-cent stamps.
  • the binary counter 34 will operate on receipt of the first pulse from the stamp counter 57 to deenergize the stamp dispenser unit 12.
  • the l-cent stamp dispensing unit 13 will continue to operate until the fourth pulse is received from the optical counter 58 at which time the binary counter 37 will operate to open the circuit to the switch 39, contacts 40 opening the circuit to the motor control unit 41 which operates to deenergize the drive motor 14 and open the circuit at contacts 43 to the solenoids 44-46.
  • the circuit in the coin acceptor unit 26 is closed through contacts 69 only to the binary counter 37 of the stamp dispenser unit 13 since there is no strapping of the jacks in the S-cent or 6-cent stamp columns. Only dispenser 13 will be activated to dispense five stamps.
  • the binary counters 27, 34 and 37 are preferably solid state counters for counting 16 numbers. Any one of the i6 count conditions may be used as a zero condition so that the output from the counters to switch assembly 39 will cause the motor 41 to operate when any one of the counters 27,34 and 37 is not in its zero condition.
  • the binary counters are connected to the optical counters 56, etc. to be advanced one step toward the zero position for each output pulse of the optical counter. Additionally, each of the binary counters has four input terminals by which the counter may be preset a different number of steps away from the zero condition in response to electrical signals at difierent ones of the input terminals.
  • the counter 27 is preferably arranged with the zero condition corresponding to a count of 16 with the input terminals connected to preset the counter one, two, four, or eight steps below l6 and with the optical counter connected to the binary counter to advance the binary counter one step for each pulse.
  • a circuit is also closed to the delay circuit 70.
  • This delay circuit 70 is arranged to operate after a suitable preselected time delay, for example 5 to 8 seconds, to energize a switch circuit 71 which operates to open contacts 72 and thus open the circuit to the motor control circuit 41.
  • the motor control circuit 41 operates to deenergize the drive motor 14 so that no additional stamps will be dispensed from any of the three stamp units 11, 12 or 13.
  • the motor control circuit 41 also operates to maintain circuit 42 energized so that contacts 43 are held closed to retain solenoids 44, 45 and 46 operated so that the coin acceptor 26 will accept no additional coins.
  • the time delay of the delay circuit 70 is chosen so that the contacts 72 will be opened only after the passage of an abnormal length of time for any one or more of the binary counters to remain operating, a situation which would indicate a malfunctioning of or tampering with the system.
  • the delay time of the delay circuit may be adjusted to any suitable time period. Contacts 43 will remain closed until the malfunctioning of the system has been corrected.
  • a suitable alarm signal such as an out-oforder light 72' (see FIG. 3) may be energized by the motor control circuit upon the opening of the contacts 72.
  • the lower portion of the stamp program board 25 includes a set of jack pairs which are utilized for providing an out-ofstamp feature for this stamp-dispensing system. These jacks are arranged in three columns, a l-cent stamp column, a 5- cent stamp column and a 6-cent stamp column. The first pair of jacks in each column is a 25-cent coin set, while the second and third pairs of jacks in each column are l0-cent coin and 5- cent coin sets, respectively. if a particular stamp denomination is dispensed from this system by a particular coin denomination, then the jack pair associated with the particular coin and that particular stamp is strapped. In the illustration we have used in describing this invention, all three stamp denominations, i.e.
  • 6-cent, S-cent and l-cent stamps are dispensed on the deposit of a 25-cent coin and, therefore, the first pair of jacks in each of the three stamp columns is strapped. Since a l0-cent coin will result in the delivery of both S-cent and l-cent stamps, the second jack pairs in the 5- cent and l-cent columns are strapped, while the second pair of jacks in the 6 -cent stamp column remains unstrapped. The third pair of jacks in the l-cent stamp column is strapped while the third pairs of jacks in both the S-cent stamp column and 6-cent stamp column remain unstrapped.
  • Out-of-stamp switches 73, 74 and 75 are provided in each of the stampdispensing units, these switch contacts remaining open so long as there are stamps available in the dispenser units for dispensing. However, should stamp dispenser unit 11, for example, run out of 6-cent stamps, the switch contacts 73 will be closed and thus a circuit closed through the first jack pair in the 6-cent stamp column to the 25-cent coin solenoid 46 which operates to disable the coin acceptor 26 from accepting any additional 25-cent coins. All 25-cent coins thereafter deposited in the coin acceptor 26 will be returned to the depositor.
  • an out-of-stamp signal may be generated, for example by light 11 (See FIG. 3) to indicate the fact that the dispenser 11 is out of 6-cent stamps.
  • the stamp dispenser system will still function to accept lO-cent coins and 5-cent coins since 6-cent stamps are not delivered from the system for these coins. if the stamp dispenser unit 13 runs out of l-cent stamps, the circuit is closed from contact 75 to all three coin solenoids 44, 45 and 46 and the coin acceptor mechanism 26 will accept no further coins and dispense no further stamps.
  • the stamp dispenser board 25 allows very flexible programming and this system is capable of accepting substantial amounts of money and dispensing substantial numbers of stamps therefor.
  • Coin acceptor mechanisms are presently available which will accept a considerable number of coins as well as bills and will hold these coins and total up the sum deposited to establish a desired credit, after which a dispense signal may be given to dispense the proper number of stamps for the total summation of money deposited and credited.
  • the dispenser units shown in this illustration included binary counters for dispensing up to stamps from each dispenser unit and for dispensing up to 45 stamps for a single coin but it should be understood that this particular selection of stamp numbers was arbitrary and that more or less stamps could be dispensed, For example, by the addition of one more flip-flop in the binary counter, up to 31 stamps may be counted and dispensed from a single dispenser. Also additional stamp dispenser units may be added to this system and the program board 25 expanded so that additional stamp denominations may be dispensed. Thus, many more combinations of coin denominations and/or stamps may be provided than are presently illustrated and such selections and variations will be obvious to those skilled in the coin-activated dispenser art.
  • the stamp-dispensing machine may be stocked with a variety of the same or different denomination stamps in the dispenser units 11, 12 and 13, and the strap connectors 29, 32, 33, etc. may be rearranged in the program board 25 to dispense any desired combination of stamps from the three dispensers 11, 12 and 13 in response to a credit signal from any of the three switches 38, 68 and 69.
  • switch 38 may be closed by a dollar bill validator or coin acceptor of the accumulator type to indicate l-dollar credit.
  • a suitable combination of connector pegs may then be used in the program board to dispense, in response to this credit signal, seven 8-cent stamps from dispenser 11, five 6-cent stamps from dispenser 12, and fourteen l-cent stamps from dispenser 13.
  • This versatility permits the machine to be used in a wide variety of applications in dispensing US. or foreign postage stamps and trading stamps. This versatility is particularly useful with the optical stamp-counting mechanism of this invention which operates easily on stamps ofdifferent physical size.

SHEET u [1F 4 INVENTORS a EBRfiiKf' P A FRANK B. LAW E 6 FRED s. MUELLE ATTORNEYS PROGRAMMED MULTIPLE STAMP DISPENSING APPARATUS EMPLOYING OPTICAL ELECTRONIC STAMP COUNTING AND AUXILIARY STAMP ROLL CAPACITY BACKGROUND OF THE INVENTION This invention relates in general to a coin-activated dispensing system and more particularly to a novel, easily programmed stamp-dispensing apparatus arranged to dispense a plurality of stamps of one or more different denominations in response to the receipt of money of one of several different denominations.
In stamp-dispensing machines presently in use the stamps are driven in a takeofi direction from the stamp supply reel by sprockets or finger members which engage the strip of stamps in the perforations between adjacent stamps. The term stamps is used herein and in the appended claims to mean roll dispensed articles, typically imprinted and perforated for separation, of the nature of a postage stamp, including such articles as trading stamps, tickets for theater and sporting events and the like. The stamps are therefore pushed or pulled through the stamp-dispensing mechanism by the moving sprockets or engaging fingers. Often times this results in a tearing of the stamps along the perforations and in a jamming of the stamp strip in the dispenser. Additionally, variations in stamp length caused by changes in manufacturing standards and changes in humidity produce stamp-feeding problems in these machines.
SUMMARY OF THE INVENTION The present invention employs a novel stamp drive apparatus which does not employ sprockets or fingers engaging the perforations between stamps, but rather employs a flexible drive member, such as a moving rubber belt, which engages the stamps across a substantial portion of their surface and carries the stamps along in an egress movement without the pushing or pulling action at concentrated areas of the stamp inherent in the prior art sprocket or finger drives. This particular stamp drive apparatus permits ease of loading and threading the stamps through the dispenser since it is not necessary to align perforations with sprockets, fingers or the like, but it is only necessary to place the stamps into contact with the belt drive, the belt drive then simply threading and carrying the stamps along through the drive unit.
In prior art dispensing apparatus, the stamps of each particular dispenser unit were contained on a single roll and dispensed therefrom, the stamp dispenser becoming inoperative upon depletion of the stamps from the supply roll. The present invention provides a novel auxiliary upon depletion of the main supply roll, is automatically brought into action to feed the first stamp of the auxiliary roll into the stamp drive mechanism immediately following the last stamp from the main supply roll. This self-threading of the auxiliary stamps into the stamp drive mechanism provides continuous, uninterrupted stamp dispensing in tandem fashion from two individual supply rolls thus doubling the stamp capacity of the unit and obviating the necessity for discarding partially used stamp rolls and refilling the stamp dispenser unit with a new roll of stamps at the beginning of a weekend period or the like.
By providing a main stamp supply roll and an auxiliary stamp supply roll, the problem of accumulating miscellaneous roll ends of various stamp roIls has been eliminated. The stamps from the main supply roll will be fully dispensed before the auxiliary supply roll is brought into operation. Thereafter, when the dispenser is serviced, the auxiliary supply roll may be moved up to the place of the main supply roll and a new reserve supply roll substituted therefor. The stamps will thereafter be dispensed from the remaining stamps on the main supply roll and the auxiliary supply roll brought into operation only when the main supply roll has been fully exhausted.
The prior stamp dispenser apparatus utilized a mechanical counting mechanism to count the number of stamps dispensed. In the present invention a novel noncontacting optical-electronic system is utilized to both accurately count the number of stamps and precisely position the stamps for cutoff of the dispensed stamps from the main stamp roll. This optical means comprises a light source positioned on one side of the stamp strip and an optical detector positioned on the opposite side of the strip, the optical detector operating in response to the passage of the line of perforations between the stamps to activate the stamp counting and stamp cutoff mechanism. This optical counter ensures accurate positioning of the stamps while also offering a degree stamps that may be dispensed from a particular dispenser unit. The optical sensing device controls the operation of the stamp cutofi mechanism to ensure that the stamps will be cut cleanly through the perforations between stamps to separate the dispensed stamps from the main supply roll. The optical-electronic mechanism provides high reliability, long life, and extreme accuracy.
The complexity of the mechanical arrangements used in prior art stamp-dispensing units for counting the number of stamps to be dispensed served to limit the total number of stamps that could be dispensed for a particular coin. The present invention utilizes a simple electronic binary counter system which operates in conjunction with the optical counting device to count the stamps, the binary counter system providing flexible and increased stamp-handling capability. A simple programming of the binary counter will permit stamp dispensing of anywhere from one to 15 or more stamps from each one or all of the stamp dispenser units for a single coin.
Stamp-dispensing machines presently in use will accept coins of several denominations and will dispense one or more stamps of one or more denominations in response to the dif ferent coins deposited. The programming of the stamps to be dispensed for the different coins accepted may be changed form time to time, but since these prior art devices utilize mechanical apparatus in the programming, changes in programming become relatively complicated and expensive. Stamp programming in the present invention is accomplished by the simple expedient of selected strapping across the jacks of an electrical programming board. The strapping may consist of manually inserting electric conducting pins in selected holes where each pin serves as the strap between two electrical jacks.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description of the stamp dispensing system of the present invention shown in schematic form in FIG. 1 will be given first, also with reference to FIGS. 3 and 6, followed by a description of latitude in the width of the I of one of the novel individual stamp dispenser units shown in detail in FIGS. 2, 4, 5 and 6.
The stamp-dispensing system comprises three separate stamp dispenser units 11, 12 and 13, although less than or more than three dispenser units may be utilized. A single main drive motor 14 and drive shaft 15 is provided having three separate drive wheels 16, 17 and 18 fixedly mounted thereon, each drive wheel being associated with a separate one of the three dispenser units (see FIG. 3). Each dispenser unit has an associated pinch roller 19, 20 and 21 operable by solenoids 22, 23 and 24, respectively, for engaging the separate stamp dispenser units with the drive wheels.
' A common stamp program board 25 is utilized to program each of the three dispenser units 11, 12 and 13 to dispense a particular number of stamps for one or another of the several coins that a coin acceptor 26 is capable of accepting. The coin acceptor 26 includes well-known devices for accepting coins of three different values. but obviously other money acceptors may be used for accepting different coins or paper money if desired.
It is assumed for the purpose of explaining the present invention that this stamp dispenser system will accept 25-cent, lO-cent and S-cent coins and also that the three stamp dispensers ll, 12 and 13 will carry 6cent, S-cent and l-cent stamps, respectively. A typical binary counter 27 of the type employed in each of the dispenser units in this system is capable of counting up to 15 stamps and consists of four two-state flipflops. The flip-flops are connected in series and count in the typical binary sequence l-2-4-8. Each binary counter is manually preset by means of the program board 25 to count a selected number for each input signal from the coin acceptor 26.
The upper portion of the program board 25 is arranged in three columns, the 25-cent coin column, the 10-cent coin column, and the 5-cent coin column, and three rows, the 6- cent stamp row, the 5-cent stamp row, and the l-cent stamp row. Each row has four pairs of jacks in each column and each pair of jacks controls one of the four flip-flop circuits in the associated binary counter. For example, referring to the 6-cent stamp row and the 25-cent coin column, the first pair of jacks 28 will set the binary counter 27 to count one, the second pair 29 to count two, the third pair 30 to count four, and the fourth pair 31 to count eight. Combinations of these jacks pairs will produce other counts; for example, strapping jack pairs 28 and 30 will set the binary counter 27 to count five, strapping jack pairs 28, 30 and 31 will set the count at 13 and strapping all fourjack pairs will set the count at 15.
In our illustration we have shown a strapping across the second jack pair 29 in the 6-cent stamp row and the 25-cent coin column which will give two 6-cent stamps for a 25-cent coin. in this same row, none of the jack pairs in the lO-cent coin column or the S-cent coin column are strapped and therefore no 6-cent stamps will be issued on receipt of a 10- cent or a 5-cent coin.
in the 5-cent stamp row, the second pair of jacks 32 in the 25-cent coin column is strapped, the first pair of jacks 33 in the 10-cent coin column is strapped, and none of the pairs of jacks are strapped in the 5-cent coin column. THis strapping sets the binary counter 34 so that, for a 25-cent coin, two 5- cent stamps will be dispensed; for a IO-cent coin one 5-cent stamp will be dispensed; and for a 5-cent coin no 5-cent stamps will be dispensed.
in the l-cent stamp row, the first and second pairs of jacks 35 and 36 in the 25-cent coin column have been strapped, and the first and third pairs of jacks have been strapped in both the lO-cent and S-cent coin columns. The binary counter 37 is thus set to count three l-cent stamps for a 25-cent coin, five 1- cent stamps for a IO-cent coin, and five l-cent stamps for a 5- cent coin.
Thus. in our illustration, the system has been preset so that for a 25-cent coin, two 6-cent stamps, two S-cent stamps and three l-cent stamps will be dispensed; for the l0-cent coin, five l-cent stamps and one 5-cent stamp will be dispensed; and for the 5-cent coin, five l-cent stamps will be dispensed.
For convenience, the strapping across jacks may consist of electrically conducting pegs and each jack pair may be two conductors forming surfaces in a hole in a pegboard, the multiple peg holes being arranged in columns and rows in the program board. The pegboard of electrical jacks is continuously made from conventional printed circuit board connectors in which conductor pins are removably inserted to connect opposite contact strips.
In operation, on receipt of a 25-cent coin, the coin acceptor 26 operates to close the circuit through switch 38 to the program board 25. Since jacks in all three rows in the 25-cent coin column have been strapped, all three stamp dispenser units 11, 12 and 13 are activated by closing ground through jack pair 29 to binary counter 27, through jack pair 32 to binary counter 34, and through jack pairs 35 and 36 to binary counter 37. The binary counters operate to close a circuit to switch 39 which operates to close contacts 40 and complete a circuit to the drive motor control circuit 41. The control circuit 41 operates to energize the main drive motor 14 to drive the wheels 16-18 and also operates switch 42 which closes a circuit through contacts 43 to the three coin solenoids 44, 45, and 46 coupled to the coin acceptor 26. Solenoid 44 is associated with the 5-cent coin mechanism and solenoids 45 and 46 with the l0-cent and 25-cent coin mechanisms, respectively, in the coin acceptor 26. These solenoids operate to disable the coin acceptor 26 from accepting any additional coins, such additional coins being returned to the depositor until such time as the system finishes its current stamp dispensing cycle.
The binary counters 27, 34 and 37 also close a circuit to the delay circuits 47, 48, and 49 which, after a short delay, for example one-half to 1 second, operate to energize the one- shot multivibrator circuits 50, 51 and 52, respectively, which transmit an energizing signal through their associated amplifier circuits 53, 54 and 55, respectively, to the pinch roller solenoids 22, 23 and 24, respectively. The pinch rollers 19-21 are moved into engagement with their associated drive wheels 16-18 and the three dispenser units ll, 12 and 13 are activated to commence dispensing stamps of all three values. The to l-second delay provided by delay circuits 47-49 gives the drive motor 14 time to get up to nonnal speed before the pinch rollers engage the drive wheels.
The stamp counter circuit 56 associated with the stamp dispenser unit 11 and shown in more detail in FIG. 6 will be described, it being understood that the counter units 57 and 58 associated with the stamp dispenser units 12 and 13, respectively, operate in similar fashion to control the number of stamps being dispensed from their particular dispenser units. The stamp counter unit 56 comprises a source of light 59 and an elongated cylindrical lens 60 which focuses the light into a strip-shaped beam, the light and lens being positioned on one side of the strip of stamps 61 such that the light beam extends transverse the stamp strip. A pair of photocell detectors 62 and 63 are positioned on the other side of the strip of stamps 61 so as to intercept the light beam. The positioning of a stamp between the light source 59 and the photo detectors 62, 63 will normally cut off or substantially attenuate the light impinging on the photodetectors. However, when the passage of the stamp aligns a line of perforations between adjacent stamps with the light beam, the light passes through the perforations and impinges upon the photo detectors 62, 63. The light impinging thereon will cause a current to flow to the pulse generator circuit 64 which operates to transmit a pulse through the amplifier 65 to the binary counter 27. At the same time, the pulse generator 64 sends a pulse to multivibrator circuit 66 which operates to produce a pulse to a totalizer counter circuit 67. The totalizer counter 67 is utilized to count the total number of stamps dispensed from the dispenser 11 between refills. A single pulse is sent to the binary counter 27 for each stamp that passes out the egress opening of the stamp dispenser. Since the binary counter 27 has been set to count two by the strapping of the jack pair 29, it will operate after receipt of the second pulse from the stamp counter unit 56 to remove the energizing signal from the delay circuit 47 to therefore deenergize the pinch roller solenoid 22 and stop operation of the 6-cent stamp dispenser unit.
During the same period, the S-cent stamps have been dispensed and the counter 34 has similarly operated in response to pulses from the optical counter 57 to count each 5-cent stamp as it passes out from the dispenser. The binary counter 34 has also been set at the two count by the strapping of a jack pair 32 and it operates on the second pulse from the counter 57 to deenergize the pinch roller solenoid 23 and terminate the dispensing of the S-cent stamps. The binary counter 37 has been set to count three by the strapping of jack pairs 35 and 36 and it operates to deenergize the pinch roller solenoid 24 after three pulses have been received from the 1- cent stamp counter 58. After the last binary counter, in this case counter 37, has operated to terminate the dispensing of stamps, it removes the energizing signal to switch 39 and the contacts 40 open to open the circuit to the motor control 41 and stop motor 14. The drive motor control circuit 41 also operates to open the contacts at 43 and thus deenergize the coin control solenoids 44, 45 and 46 so that the coin acceptor 26 will be placed in a condition to accept the next coin deposited.
When a lO-cent coin is deposited in the coin acceptor 26, a circuit is closed through contacts 68 to the stamp board 25. Since there is no strapping across any of the pairs of jacks in the lO-cent coin column and 6-cent stamp row, the 6-cent stamp dispenser unit 11 will not be activated by the IO-cent coin. The strapping across the first pair of jacks 33 in the cent coin column and S-cent stamp row will activate the stamp dispenser unit 12 while the strapping across the second and third pairs of jacks in the IO-cent coin column and l-cent stamp row will activate the stamp dispenser unit 13. The binary counter circuits 34 and 37 will energize the switch circuit 39 to close contacts 40 and energize the drive motor 14. The motor control circuit 41 will energize the switch 42 to close contacts 43 and operate solenoids 44, 45 and 46 to prevent the coin acceptor 26 from accepting additional coins. The stamp dispenser unit 12 will operate to dispense S-cent stamps and unit 13 will operate to dispense l-cent stamps. The binary counter 34 will operate on receipt of the first pulse from the stamp counter 57 to deenergize the stamp dispenser unit 12. The l-cent stamp dispensing unit 13 will continue to operate until the fourth pulse is received from the optical counter 58 at which time the binary counter 37 will operate to open the circuit to the switch 39, contacts 40 opening the circuit to the motor control unit 41 which operates to deenergize the drive motor 14 and open the circuit at contacts 43 to the solenoids 44-46.
In the case of 5-cent coin being deposited, the circuit in the coin acceptor unit 26 is closed through contacts 69 only to the binary counter 37 of the stamp dispenser unit 13 since there is no strapping of the jacks in the S-cent or 6-cent stamp columns. Only dispenser 13 will be activated to dispense five stamps.
As indicated above, the binary counters 27, 34 and 37 are preferably solid state counters for counting 16 numbers. Any one of the i6 count conditions may be used as a zero condition so that the output from the counters to switch assembly 39 will cause the motor 41 to operate when any one of the counters 27,34 and 37 is not in its zero condition.
The binary counters are connected to the optical counters 56, etc. to be advanced one step toward the zero position for each output pulse of the optical counter. Additionally, each of the binary counters has four input terminals by which the counter may be preset a different number of steps away from the zero condition in response to electrical signals at difierent ones of the input terminals.
The counter 27 is preferably arranged with the zero condition corresponding to a count of 16 with the input terminals connected to preset the counter one, two, four, or eight steps below l6 and with the optical counter connected to the binary counter to advance the binary counter one step for each pulse.
At the time that one or more of the binary counter circuits 27, 34 and 37 operate to close a circuit to the motor control 41, a circuit is also closed to the delay circuit 70. This delay circuit 70 is arranged to operate after a suitable preselected time delay, for example 5 to 8 seconds, to energize a switch circuit 71 which operates to open contacts 72 and thus open the circuit to the motor control circuit 41. The motor control circuit 41 operates to deenergize the drive motor 14 so that no additional stamps will be dispensed from any of the three stamp units 11, 12 or 13. The motor control circuit 41 also operates to maintain circuit 42 energized so that contacts 43 are held closed to retain solenoids 44, 45 and 46 operated so that the coin acceptor 26 will accept no additional coins. The time delay of the delay circuit 70 is chosen so that the contacts 72 will be opened only after the passage of an abnormal length of time for any one or more of the binary counters to remain operating, a situation which would indicate a malfunctioning of or tampering with the system. The delay time of the delay circuit may be adjusted to any suitable time period. Contacts 43 will remain closed until the malfunctioning of the system has been corrected. A suitable alarm signal such as an out-oforder light 72' (see FIG. 3) may be energized by the motor control circuit upon the opening of the contacts 72.
The lower portion of the stamp program board 25 includes a set of jack pairs which are utilized for providing an out-ofstamp feature for this stamp-dispensing system. These jacks are arranged in three columns, a l-cent stamp column, a 5- cent stamp column and a 6-cent stamp column. The first pair of jacks in each column is a 25-cent coin set, while the second and third pairs of jacks in each column are l0-cent coin and 5- cent coin sets, respectively. if a particular stamp denomination is dispensed from this system by a particular coin denomination, then the jack pair associated with the particular coin and that particular stamp is strapped. In the illustration we have used in describing this invention, all three stamp denominations, i.e. 6-cent, S-cent and l-cent stamps, are dispensed on the deposit of a 25-cent coin and, therefore, the first pair of jacks in each of the three stamp columns is strapped. Since a l0-cent coin will result in the delivery of both S-cent and l-cent stamps, the second jack pairs in the 5- cent and l-cent columns are strapped, while the second pair of jacks in the 6 -cent stamp column remains unstrapped. The third pair of jacks in the l-cent stamp column is strapped while the third pairs of jacks in both the S-cent stamp column and 6-cent stamp column remain unstrapped. Out-of-stamp" switches 73, 74 and 75 are provided in each of the stampdispensing units, these switch contacts remaining open so long as there are stamps available in the dispenser units for dispensing. However, should stamp dispenser unit 11, for example, run out of 6-cent stamps, the switch contacts 73 will be closed and thus a circuit closed through the first jack pair in the 6-cent stamp column to the 25-cent coin solenoid 46 which operates to disable the coin acceptor 26 from accepting any additional 25-cent coins. All 25-cent coins thereafter deposited in the coin acceptor 26 will be returned to the depositor. In addition, an out-of-stamp signal may be generated, for example by light 11 (See FIG. 3) to indicate the fact that the dispenser 11 is out of 6-cent stamps. It should be noted that the stamp dispenser system will still function to accept lO-cent coins and 5-cent coins since 6-cent stamps are not delivered from the system for these coins. if the stamp dispenser unit 13 runs out of l-cent stamps, the circuit is closed from contact 75 to all three coin solenoids 44, 45 and 46 and the coin acceptor mechanism 26 will accept no further coins and dispense no further stamps.
The stamp dispenser board 25 allows very flexible programming and this system is capable of accepting substantial amounts of money and dispensing substantial numbers of stamps therefor. Coin acceptor mechanisms are presently available which will accept a considerable number of coins as well as bills and will hold these coins and total up the sum deposited to establish a desired credit, after which a dispense signal may be given to dispense the proper number of stamps for the total summation of money deposited and credited. The dispenser units shown in this illustration included binary counters for dispensing up to stamps from each dispenser unit and for dispensing up to 45 stamps for a single coin but it should be understood that this particular selection of stamp numbers was arbitrary and that more or less stamps could be dispensed, For example, by the addition of one more flip-flop in the binary counter, up to 31 stamps may be counted and dispensed from a single dispenser. Also additional stamp dispenser units may be added to this system and the program board 25 expanded so that additional stamp denominations may be dispensed. Thus, many more combinations of coin denominations and/or stamps may be provided than are presently illustrated and such selections and variations will be obvious to those skilled in the coin-activated dispenser art.
The stamp-dispensing machine may be stocked with a variety of the same or different denomination stamps in the dispenser units 11, 12 and 13, and the strap connectors 29, 32, 33, etc. may be rearranged in the program board 25 to dispense any desired combination of stamps from the three dispensers 11, 12 and 13 in response to a credit signal from any of the three switches 38, 68 and 69. By way of example, switch 38 may be closed by a dollar bill validator or coin acceptor of the accumulator type to indicate l-dollar credit. A suitable combination of connector pegs may then be used in the program board to dispense, in response to this credit signal, seven 8-cent stamps from dispenser 11, five 6-cent stamps from dispenser 12, and fourteen l-cent stamps from dispenser 13. This versatility permits the machine to be used in a wide variety of applications in dispensing US. or foreign postage stamps and trading stamps. This versatility is particularly useful with the optical stamp-counting mechanism of this invention which operates easily on stamps ofdifferent physical size.
Referring now to FIGS. 2 and 4 through 6, there is shown one of the three novel stamp dispenser units 11 comprising a main mounting plate 81 on which first and second rolls of stamps 82 and 83 may be mounted, each roll containing 3,000 stamps. The stamps 61 from the upper or main stamp roll 82 are threaded around an idler pulley 84 and into one end of the upper level of an open-ended, elongated stamp guide 85. The stamps pass through the stamp guide 85 and over the top portion of a drive wheel 86 which is rotatably mounted on the support plate 81. The drive wheel 86 carries two rubber drive belts 87 which also pass over two idler pulleys 88 and 89 mounted at the front of the support plate.
A pair of elongated, rectangularshaped support members 91 and 92 are pivotally mounted on the main support plate 81 by pivot pin 93, the pin 93 also carrying a rotatable belt drive wheel 94. A second belt drive wheel 95 is rotatably mounted on a shaft 96 at the opposite end of the rectangular support members 91 and 92. a pair of rubber belts 97, 98 are mounted on the two belt drive rollers 94, 95, these two belts extending between the rollers 94, 95 and engaging the stamps 61, which pass over the upper portion of the drive pulley 86.
A second pair of roller support plates 99, 101 are pivotally mounted on the shaft 96 and in turn carry and auxiliary drive roller 102 mounted on a shaft 103. A rubber drive belt 104 extends around the two drive rollers 95, 102 and between the pair of bolts 97, 98 and serves to drive the auxiliary roller 102 in a clockwise direction as the drive roller 95 rotates. A spring 105 coupled at one end to a pin 106 on the support member 99 and at its other end to another pin 107 on the other support member 91 serves to urge the auxiliary drive wheel 102 and belt 104 in a clockwise direction into engagement with the stamps 61 in the stamp guide 85. A drive belt 108 encircles the drive wheel 94 between the pair of belts 97, 98 and passes around the two idler pulleys 109, 110 mounted at the front of the main support base 81.
The stamps 111 from the auxiliary or backup stamp roll 83 are threaded into the bottom portion of the stamp guide 85 with the first stamp positioned directly under the stamp from the first roll 82 which is under the drive wheel 102. Switch 73 is mounted on the support plate 81 and carries a pivotally mounted contact arm 113 which is urged into engagement with the stamps 61.
A U-shaped pinch roller support member 114 is pivotally mounted on the main support plate 81 by means of a pivot in 115 and is coupled to the armature 116 of a pinch roller drive solenoid22 mounted on the plate 81, the support 114 having the rubber pinch roller 20 rotatably mounted between the legs thereof.
A knife plate 118 is mounted in a knife guide 119 at the front of the support plate 81, the upper end of the knife plate 118 being supported at the front end 121 ofa lever arm 122 which is pivotally mounted by means of a pivot pin 123 on the support plate 81. A connector arm 124 is pivotally mounted at one end on the lever arm 122 by a pin 125 and is also mounted via slot 124 at its other end on the shaft 126 of the pinch roller 19 and couples the pinch roller 19 to the stamp cutoff knife 118. Tension springs 127 and 128 are mounted between the mounting shaft of the idler pulley 89 and the mounting pin 129 on the upper portion of the knife plate 118 and urges the knife plate and the lever arm 122 in a downwardly direction, also urging the pinch roller support member 114 via am 124 in a counterclockwise direction, the stop member 130 on the -support 114 being urged against the drive pulley 86 and serving as a brake.
An electronically operated stamp counter 67 is also secured on the main support plate 81.
A plug-in circuit board 131 is mounted on the support plate 81 and carries the light source 59 at its lower end which directs light into the elongated cylindrical lens 60, the lens serving to focus the light into a strip extending transverse to the strip of stamps 61 extending between the belt drives 87 and 108. The pair of photodetectors 62, 63 are mounted on the circuit board 131 above the stamps 61 and aligned with the beam of light passing through the perforations in the stamps as the line of perforations between stamps passes between the lens and the photodetectors. The plug-in circuit board 131 also carries the remainder of the circuit elements of the optical counter circuit 56.
ln the use of this stamp dispenser, the stamps 61 from the upper stamp roll are threaded through the upper level or channel of the stamp guide 85 and under drive wheels 102 and 95 into engagement with the drive wheel 86. The drive wheel 86 is then manually rotated in a counterclockwise direction to feed the stamps over the top of the drive wheel 86 and under the drive belts 97, 98, the drive wheels 94, 95 being driven by the belts 97, 98. The stamps pass under the drive wheel 94 and belt 108 toward the opening 132 in the knife plate 118. The stamps 111 from the lower stamp reel 83 are then inserted into the lower level or channel of the stamp guide 85. The stamps 111 remain stationary until such time as the stamps 61 from the upper roll have been completely expended. The first stamp in the strip of stamps 61 is positioned with its front edge closely spaced from the back of the knife plate 118. The circuit board 131 is preferably positioned so that the line of perforations between the first and second stamps is located to the right of the point of interception of the light beam from the light source 59 as viewed in FIG. 2. With the stamp dispenser in the inactivated condition, the solenoid 22 is not energized and the pinch roller bracket 114 is urged by springs 127, 128 acting through arm 124 into a position with the brake 130 against the drive wheel 86. The drive wheel 86 is thus held locked and the pinch roller 19 disengaged from both the drive wheel 16 and the drive wheel 86. The lever arm 122 is also in the lowermost position and thus positions the knife plate 118 so that the opening 132 in the knife is out of alignment with the stamps 61, thus closing off access to the stamps from outside of the stamp dispenser.
When stamps are to be dispensed from this dispenser, the drive wheel 16 is first driven in counterclockwise direction by the drive motor. The pinch roller solenoid 22 is then activated and moves its armature to the left thus rotating the U-shaped bracket 114 in a clockwise direction about the pivot pin 115.
The brake member 130 is disengaged from the drive wheel 86 and the pinch roller 19 brought into engagement with both the motor drive wheel 16 and the stamp drive wheel 86, the stamp drive wheel 86 being driven in a counterclockwise direction to feed the stamps 61 under the drive belts 97, 98 and to the left as seen in FIG. 2. Moving in a clockwise direction, the U- shape member 114 also, through arm 124, raises the lever arm 122 and thus raises the knife plate 118 so that the opening 132 is brought into alignment with the stamps 61, thus permitting the stamps 61 to pass out through the opening 132.
As the lines of perforations between each successive pair of stamps pass between the light source 59 and the photocells 62, the stamp count pulses are generated as described above until the preselected number of stamps passes out from this particular stamp dispenser unit. When the binary counter 27 has counted the particular preset number, the solenoid 22 is deenergized and the spring-loaded U-shape member 114 is rotated in a counterclockwise direction by the springs 127, 128 to disengage the pinch roller 19 from the drive wheel 16 and stamp drive 86 and at the same time engage the brake member 130 with the stamp drive wheel 86 to prevent further stamp dispensing. The lever arm 122 also moves in a downward direction to cause the knife blade 118 to move downwardly under the urging of springs 127, 128. The two sharp knife edges 132 in the upper edge of the egress opening 132 cut the strip of stamps through the line of perforations behind the last stamp to be dispensed. The next stamp in the stamp strip 61 is in position behind the knife plate 118 for the next cycle in response to the next coin deposited.
The optical counter 56 mounted on circuit board 131 is preferably provided with an adjustable delay timer (suitably in the form of a potentiometer 131' in an RC timing circuit) to provide an adjustable time delay between the time a line of stamp perforations passes the photocells 62 and 63 and the time a pulse is delivered from the counter 56 to the counter 27. The potentiometer is adjusted so that the knife 118 falls on the last line of perforations detected by the photocells 62 and 63. In this way, the machine will operate to dispense stamps properly regardless of the length of the stamps. When the stamps to be dispensed are shorter than the distance between photocells 62 and 63 and the knife 118, the potentiometer 131 is adjusted to drop the knife 118 on the second to last line of stamp perforations detected, leaving a complete stamp between the knife and photocells.
Stamps will be dispensed form the upper roll 82 in response to successive activation by particular coins in the abovedescribed manner until such time as the roll 82 has been depleted. As long as there are stamps 61 in the upper channel of the stamp guide 85, the drive wheel 102 will ride on top of these stamps 61; Whenthe last of the stamps in the strip 61 passes under the auxiliary roller 102, this roller rotates downwardly in a clockwise direction about pin 96 and into engagement with the stamps 111 positioned in the lower portion of the stamp guide 85. The drive wheel 102 is urged in a downwardly direction under the tension of spring 105, the drive wheel 102 being driven in a clockwise direction by the drive belt 104 from the drive wheel 95. The drive belt 104 drives the end of the stamps 111 into engagement with the stamp drive wheel 86 and under the drive belts 97 and 98. The beginning end of the stamps 111 on the roll 83 thus follows after the tail end of the stamps 61 from the roll 82.
As long as there are stamps 61 in the upper channel or stamps 111 in the lower channel of the stamp guide 85, the switch arm 113 will ride on the stamps. When the last stamp from the roll 83 passes through the lower channel in the stamp guide 85, the lever arm 113 rotates downwardly and closes the switch 73 which operates as described above to give an outof-stamps signal and to disable the coin acceptor in the system so that further coins will not be accepted to operate this particular stamp dispenser unit.
The binary counters 27, 34 and 37 on the trailing edge of the through 58, respectively,
are designed to operate pulses from the optical counters 56 so that the operation of the stamp wherein said drive and the stamp'cutting knife is independent of the width of the various strips of perforations between stamps. By operating on the trailing edge of the pulse from the optical counter, the stamp dispenser unit will also be uneflected by the fact that a substantial gap may appear between the last stamp from the upper roll 82 and the firststamp from the lower auxiliary roll 83 during the switch over from the main roll of stamps to the auxiliary roll.
If someone should succeed in prying the knife plate 118 up from the outside to expose the end of the stamps through the opening 132, the arm 124 will also move upwardly. The slot 124 will permit the U-shaped member 114 to remain stationary with brake against the drive pulley 86, thus preventing the stamps from being pulled from the dispenser.
Another form of dispenser unit that may be utilized in lieu of the dispenser unit shown in FIG. 2 is shownin FIG. 7; apparatus in FIG. 7 which is similar to that of the dispenser unit in FIG. 2 bears the same reference number. In this dispenser unit, an individual drive motor coupled tothe stamp drive wheel 86 via drive belt 136 is utilized in place of the common drive motor 14 and individual drive wheel 16. This individual drive motor 135 is energized only when the stamps from this particular dispenser unit are to be dispensed in response to the deposit of the proper coin in the coin acceptor unit. At the time the drive motor 135 is energized, a knife-actuating solenoid 136 is also energized to move the knife plate 118 to its uppermost position so as to align the opening 132-in the knife plate 118 with the stamps. After the proper number of stamps have been fed out from the dispenser unit, the drive motor 135 is deenergized and the knife solenoid also deenergized 136, the knife returning under the force of the spring 127 to cut the projecting stamps from the stamp strip. 7
