corporation of Delaware Application May 2, 1939, Serial No. 271,258 in Great Britain May 1.1, 1938 16 Claims. 01. 242-355) V This invention relates to apparatus for winding yarn into cheeses, the invention being es-- pecially concerned with apparatus in which the of material to be wound is maintained.

The winding apparatus according to the invention comprises drum means adapted to drive a cheese occupying a winding position in contact with the surface of. said drum means, means to withdraw a completed cheese from said Winding position and to transfer a cheese carrier into said winding position, means for traversing a thread lengthwise of the cheese in said winding position, and means for engaging the thread between said traversing means and a completed cheese and for carrying said thread into engagement' with the cheese carrier being transferred into said winding position.

Preferably, the movements of the completed cheese out of and of the replacement carrierinto winding position are in a direction transverse to the axes of the cheese and the carrier and the movement of the relacement carrier into winding position is effected in such a waythat before reaching the position the carriercomes into contact with the drum means so that it is rotating at yarn winding speed when it reaches winding position and the transfer of the yarn is effected. Further, provision is preferably made for maintaining the completed cheese in rotation while it is being moved from winding position so that winding proceeds without a break except for the transfer of the thread from the cheese to the replacement carrier. I

The surface driving means for the cheese advantageously comprises a pair of drums arranged side by side so that the package can rest between them, both drums preferably being driven.

The cheese rides steadilyabove and between the two drums and a smooth drive is transmitted to the cheese whatever its diameter as it builds up in size. During the doffing and donning operation the completed cheese is moved out of contact with one drum but retains its'contact with the other, so that winding continues until the replacement carrier is in contact with both drums- The setting into rotation of the replacement carrier is effected by bringing it into contact with the drum first left by the completed cheese and causing it to roll over this drum until it makes contact also with the other drum. In order to effect the transfer a carriage may be provided on which are provided means to engage the completed cheese and the replacement carrier; so that in one movement of the carriage the cheese is moved out of winding position and the replacementcarrierbrought into winding position. Supporting arms are provided to receive a further re- 1(]' placement carrier aitenone dofling operation, so thatwheu the next operation is started a reverse movement or the carriage engages the new carrier.

Replacement carriers may be put into position and completed cheeses removed by hand after each doiiing and donning operation, or the carriers may be supplied from a magazine and the cheeses allowed to roll or slideaway so that the operation is completely automatic.

The dofllng and donning operation may be initiated by any suitable mechanism operating driving drums, or by a suitable clock mechanism operating at uniform time intervals. A number of winding units may be controlled by a single mechanism so as to dofi their cheeses simultaneously.

The apparatus according to the invention is particularly useful for winding cheeses in apparatus for the manufacture of "artificial silk which produces yarn without interruption over very long periods. The apparatus is suitable both for high speed winding, as is necessary in the case of dry-spinning apparatus such as is used for the manufacture of cellulose acetate artificial silk. or for the lower speed operation usual with wet-spinning apparatus such .as is used for the production of viscose or cuprammonium artificial silk.

One form of winding apparatus according to the invention will now be described in greater detail with reference to the accompanying drawings in which Fig. l is a diagrammatic front elevation of winding means according tothe invention as applied to a machine for spinning a large number of threads of artificial silk;

Figs. 2 to 4 are sectional side elevations of the winding means shown in Fig. l;

Figs. 6, 7 and 8 show details of the mechanism on a still larger scale;

Fig. 9 is a diagrammatic representation of the electrical circuits employed in conjunction with the mechanism;

Fig. 10 is a cross-section through one of the driving rollers of the mechanism and Fig. 11 is a diagrammatic view of a package support employed for the purposes of the invention. As is shown in Fig. 1 the whole apparatus comprises a plurality of winding imits for winding a large number of artificial yarns simultaneously produced by a spinning machine I". Thewinding units are adapted for the simultaneous dofllng and donning of the packages and package supports under the control of a common mechanism shown at the right-hand end of Fig. 1 and in Figs.

Each of the winding units comprises a pair of driving rollers I, 2 arranged parallel to each other so as to support between them a package being,

wound (shown at 3, Figs." 5, 8 and 8). The package being wound is provided with a spindle 4 which during the growth of the package can ride up vertical slots in a pair of side plates 4, one on each side of each winding unit until, when the package is completed, it rises out of the slots. During the winding of a package, an empty replacement carrier 1 rests in stationary supporting arms 3 secured to the frame of the machine above and somewhat to the rear of the rear driving roller 2. On completion of winding the completed package (indicated at 44) is carried over the roller I until it rests at 3 in supporting stops It. At the same time the replacement carrier 1 is removed from the supporting arms I and brought over the roller 2 until it rests on both rollers, I and 2, in the position 3. The yarn 61 (Figs. 2 to 5) is traversed along the package 3 by a guide II, being led from the spinning machine IM to the guide II in the manner shown in Fig. 5. The guide II is supported by guide wires I2 disposed between the rollers l and 2, and

the thread 61 is transferred during the dofiing and donning operationfrom the completed package 68 to the replacement carrier 1 by means of a throw-on arm I3 having a portion ill at its end parallel to the axes of the rollers I, 2, the

J the package in. each winding unit, the control of the mechanism in this manner being effected by means of a master controller I! (Figure 9) driven by gearing, to be described hereafter, in connection with the gearing for driving the rollers I, 2.

As shown in Fig. 1 the several winding units are mounted in two rows one above the other, the units of one row being staggered with respect to those of the other so that each upper unit does not lie immediately above a lower unit. The rollers I, 2 are mounted respectively on shafts l6, II which are common to half the units employed, one pair ofshafts I6, I'l being provided for the upper units, and another for the lower units. The shafts l6, II are driven from a waste 'gears 44 (Fig. 6), two foreach winding unit,

roller shaft II by means of a chain 20 (Fig. 4). A chain I I3 and sprocket I I8 (Fig. 9) drive the master controller I3 from the waste roller shaft I4. At the middle of the machine the waste roller shaft I! also drives, by means of a chain III and sprockets I44, I93, ashaft I9 running the length of the machine. At the ends of the machine, driving connection is made by means of sprockets I23 and chains I 2| between the shaft II and two transverse cams 2 I, by means of which the two sets of traverse wires I2 are driven, the traverse wires being secured at each end to cam followers 2 and stretched under tension from one cam to the other along the whole length of the machine. This arrangement of drive for the cams 2| ensures that there is no angular displacement or phase difference between the two cams.

In the chain drive III, I80, I93 between the waste roller shaft II and the longitudinal shaft I for driving the cams 2i is included a ribbonbreaking device comprising a crank lever gear 22 driven from the shaft is at a slow rate by means of a chain 23 and reduction gears I23. The crank lever gear 22 operates a chain wheel rocker bracket in the form of a plate 24 pivoted on the shaft I3, and carrying Jockey sprockets I24 engaging with the chain 8 between the shafts I3, II. The slight oscillation of the bracket 24 by the crank lever gear 22 pulls the slack of the chain III first to one side and then to the other of the shaft I3," superimposing a slight backward'and forward movement of the shaft I9 on the continuous drive of the chain 3.. By these means the effective driving rate of the chain II3 on the longitudinal shaft is is slowly and very slightly increased and decreased alternately, im-

parting a corresponding variation to the rate of the waste roller shaft It at arate such that a definite number of revolutions of the shaft 24 provides for the operation of the mechanism used to effect the dofllng and donning operation. On the shaft 26 is a magnetic clutch 29 which is caused to engage with the shaft 28 by the master controller l5 and serves, when so engaged, to drive, through reduction gearing 30 secured to the shaft 28, (Figs. 1, 3 and 7) the dofllng and donning control mechanism. From the gearing 33 (see Fig. 7) a chain drive 3| extends to a shaft 32 carrying spur gears 33, 34, the first of which meshes directly with a spur gear 35 on a clutch member 33 and the other through an idler pinion 31 with a spur gear 33 on a clutchmember 33. The members 33 and 38 are carried by a common shaft 43 provided with sprockets 4|, 42 connected (see Figs. 1 and 3) by chains I4I, I42 to sprockets I43 on two shafts 43. The shafts 43 constitute the main drive of the dofling and donning mechanism and by the means described above they may be driven in one direction or the otheraccording as the clutch 3B or the clutch 39 is in engagement.

On the operating shafts 43 are secured helical meshing with corresponding gears 45 which are screwed internally and mounted on the screwed ends of the slide rods I4. An intermediate clutch member 46 is provided between the clutch members 36 and 39 and is adapted to en age with either of them alternatively, the intermediate clutch member 46 being splined to the shaft" so 'as to connect the clutch member 36 or 39 to said shaft. When the clutch member 36 is conanc or nected to the shaft 49 the helical gears 44, 49 are driven in such a direction that the slide rods 14 are drawn rearwards of the domng and quent rotation of theshaft 26, however, a crank 41 (shown in Fig. 7) is slowlyrotated b'eing driven through bevel gears 48, 49 chaindrivjen from the shaft 26. Thecrank 4| acting through a connecting rod 50 and an adjustable slide rod Bl moves the operating lever 52 of the intermediate clutch member 49 against the action of a toggle spring 53. Until the central position of the lever 52 andthe togglespring 52 has been reached the member 46 is not aflected, there being a suitable open fork connection 54 between the lever 52 and the member 46, to give lost motion. As the toggle spring I3 passes this central position, however, it rapidly continues the motion of the lever 52, the adjustable slide rod 5| being provided with a slot 55 at its connection with the lever iz to aliow this rapid movement to take place independently of the slide rod 5|. The rapid movement of the lever 52 under the action of the toggle spring 53 suddenly disconnects the member 46 from the clutch member 38 and connects it to the clutch member 39. This reverses the direction of motion of the slide rods I4 so that they move forward again until the continued revolution'of the crank 41 again changes the position of the intermediate clutch member 48. A lever 56 and a toggle spring 51 are provided to hold the clutch member 49 in one position or the other while the lost motion of the fork 54 is being taken up.

After one revolution of the crank 41, durin which the position of the intermediate clutch member 46 is twice changed, the magneticclutch 29 is disconnected so as to bring the mechanism to rest. This is done by means of a cam II shown in Fig. 9, carried on a shaft Inf and driven by means of gearing l3 9 from the shaft 29. at the same speed as the crank 41. The cam 59 after one revolution operates a switch 99 that short circuits a lowtension solenoid switch 69.

their forward motion the completed package is drawn by the catches 95 out of contact with the rear driving roller 2, and is rolled over theforward roller l. the winding of the yarn 61 onthe completed package 66 continuing while contact is maintained between the roller i and the completed package. As the completed package 69 is'inoved forward the points 62 engage'the spindie 64 and lift the replacement carrier I from the arms 8, allowing it to fallen to the-rear roller 2 su 'that the carrier I begins to rotate. By the time the carrier I falls into contact with both rollers I and 2 its periphery is moved at full yarn speed. As the slide rods l4 approach their foremost position the completed package leaves the roller I and occupies the position I. At this point the portion "I or the throwon arm I3 is caused to pass through the space between the package at 9 and the. roller l, the

portion Iii engaging the. yarn 61 proceeding from the guide II to the package now'at 9 and carrying it over the top of the replacement carrier. I now in'the positionof the package 3. The yarn is thus brought into arc contact with the replacement'carrier I, the surface-of which may be suitably roughened, say over a centre portion as shown in Fig. 11 at 68. In this manner the yarn is secured to the replacement carrier land broken from the completed package, at 9' Winding thus continues on the replacement car rier I. The operation of the throw-on arm I2 through the successive positions shown in dotted lines in Fig. 8 is effected by means of scam 69 on the side of one of the siide'rods I4, the cam 69 operating a lever Ill provided with a. nose II for the engagement of the cam 69. The lever 19 .carries the throw-on arm I! which is also supported by meansof a pivoted guide I2, the proportions of the lever 19 and throw-on arm J3 and the position of the' guide 12 being suchas to cause the throw-on arm i3 to follow the desired movements as indicated in dotted lines inFis. 8.

'. The master controller l5v shown inFig. 9'con- .tains a low tension switch and a gear driven troller i5 is arranged in series with a solenoid 14 connected to the low tension side of the trans former il the high tension side of which is cons nected to a source 96 of alternating currents When the master controller l5 operates to close" its internal switch the completion of the circult through the solenoid 14 causes the solenoid 0! the slide rods H as follows (Figs. 6 and 8).

During the rearward movement of the slide rods 14 and side plates 6 (i. e. the movement, in Figs.

and behind (i. -e. in Fig. 6, to the right of) the projecting e'ndsof the spindle 4 of the nearly completed package shown at 66. The motion of the'slide rods I4 is then reversed, and during to'attract the arm 15 of a switch 60 which makes the circuit self-sustaining. This enables the master controller to be reset, the drive for this purpose being from the shaft I58 through sprockets I59, I69, and chain IBI. A second solenoid I9 is arranged in circuit with the first solenoid l4 and this serves to close a high ten-. sion switch I1 in the circuit of the magnetic clutch 29 whereby the magnetic clutch 29-is operated and dofllng and donning is effected as previously described. Near the end of the dofling and donning cycle a cam 59 opens the trip switch 99 and short circuits the solenoid I4, so allowing the switch 60 to open, breaking the circuit of the solenoid 16 and allowing the switch 11 to .open. In this manner the magnetic clutch 29 is disconnected after ning have taken place.

doiiing and donmoval of any waste that may have been caught on them. These means are shown in Fig. in

which it may be seen that each roller is freely mounted on its driving shaft It or I! (I8 in Fig. 10) and is urged endwise by means of a spring I8 engaging with a collar 18 pinned to the shaft IS. The endwise pressure of the spring 18 upon the roller I causes dog clutch teeth 88 carried on a spider 8I at one end of the roller I to engage with corresponding teeth on a disc 82 pinned at 83 to the driving shaft I6. Adjacent to the driven end of the roller I is a sleeve 84 internally threaded with a quick start thread 85 and. screwed on a corresponding-member 88 secured to a frame member 81 carrying a bearing 88 for the shaft I8. An end of thesleeve 84 is overlapped by the end of the roller I and carries 'a friction disc 88 for engagement with the surface 98 of the roller spider 8 I When the sleeve 84 is rotated by hand the quick start screw 85 causes it to engage the roller I and to push it endwise against the action of the spring I8 until the teeth 80 on the roller I disengage the teeth on the disc 82 secured to the shaft I8. At the other end of the roller I another sleeve SI fixed to a shaft hearing frame 92 is overlapped by the barrel of the roller I and is fitted with a friction ring 83 that comes into contact with the surface 94 of a spider 85 at that endof the roller when the roller is pushed endwise. In this manner by rotation of the sleeve 84 the roller I is freed from its drive through the teeth 80 and by the engagement of the friction surfaces 89, 98, 93, 84 is brought to rest. Release of the screwed sleeve 84 allows.

the spring I8 to return the roller I to driving position. The screwed sleeve 84 is normally held out of engagement with the roller I by means of spring pressed bal1s 91 in the member 86, which engage with grooves 98 inside the sleeve 84. The sleeves 84, 9| may be cut concavely so that waste collected on the roller I can be slid on to them for final removal.
