3,134,326 MACHHQERY FOR APPORTIONING AND DISPENSING FLUIDS William F. Davis, Windsor, NJ. (1 29. Box 179, Hightstown, NJ.) Filed July 15, 1959, Ser. No. 827,244 Claims. (El. 101-366) The present invention relates to new and useful improvements in the method of and the machinery for the apportioning and dispensing of fluids. More particularly, the invention is concerned with fluid dispensing as applied to inking mechanism of printing presses.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by the instrumentalities and combinations pointed out in the appended claims.

The invention consists in novel parts, constructions, arrangements, combinations and improvements herein described and disclosed.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate the embodiments of the invention, and together with the description, serve to explain the principles of the invention.

The present invention has for its object the provision of a novel and improved method of apportioning and dispening fluid, such as ink, and the machinery to accomplish this improved method of apportioning and dispensing of fluid.

The prime object of the present invention is to provide a means to apportion and dispense fluids, suchas ink, in a continuous flow from a plurality of orifices in individually controllable quantities.

A second object of the present invention is to provide a means of remote control of the plurality of fluid volumes being apportioned and dispensed both individually and in combination with each other collectively.

A further object of the invention is to provide a simple mechanical means to change the ink supply.

Other objects and advantages of the invention will become apparent to those skilled in the art.

While the invention is susceptible of various modifications and alternate constructions and uses, I have depicted in the drawings and disclosed in detail herein preferred embodiments of the invention. It is understood, however, that the broader aspects of the invention are not limited to the specific mechanisms shown and described but de partures may be made therefrom within the spirit and scope of the accompanying claims without sacrificing its concomitant benefits and advantages. Therefore, I do not intend to limit the invention by the aforementioned drawings and description but intend to cover all modifications and alternate constructions falling within the spirit and scope of the invention as expressed in the appended claims.

In the following, the invention will be disclosed as applied to a printing press and therefore the terminology will conform to that employed in ink feeding mechanisms as employed in printing presses. In accordance with the illustrative embodiment shown in FIGURES 1, 2 and 3 the fluid dispensing means consists of a series of laterally disposed ink pumping elements mounted on a structural member which extends the width of the press.

Referring to FIGURE 2, the pumping mechanism consists of a tubular channel, commencing at the ink supply and extending through the pump to the ink egress orifice. Said channel is divided into three chambers; the first chamber 1, provides an ingress for the ink from the ink supply or sump to the first pressure responsive valve 2; the second chamber 3, in which pressure variations required to actuate the-chamber valves 2 and 4, are developed and volumetric variations are produced to measure the fluid volume dispensed per unit pumping cycle.

The third chamber 5, provides the egress for the controlled fluid feed to the press ink motion. Chamber 5, is equipped with a resilient section in its wall to absorb pressure peaks and to filter the pulse feed of the ink into a smooth continuous discharge flow. For illustrative purposes the resilient portion of the third chamber 5, is shown as a ball 6, with a spring 7, to oppose the fluid pressure.

Operation of the Fluid Handling Mechanism Referring to FIGURE 2, an electric pulse of current is passed through coil 9, establishing a magnetic field which causes ball 8, to be displaced toward the excursion limit rod 10, and thereby stores strain energy in spring 11, as well as producing a reduction of pressure in chamber 3, below the pressure of chamber 1. The pressure sensitive valve 2, opens and admits ink'fluid in proportion to the ball 8, excursion in chamber 3. Upon decay of the electromagnetic field the stored energy of spring 11, displaces the ball 8, toward valve 2. Valve 2 and valve 4 are constructed to have unidirectional action, hence valve 2 is prevented from opening except when flowing fluid into chamber 3 as illustrated in FIGURE 2; and valve 4 is prevented from opening except when flowing fluid out of chamber 3. As the ball 8, moves toward valve 2 the fluid in chamber 3 is forced to flow through valve 4 into chamber 5. In chamber 5 the fluid pressure forces ball 6, to recede, compressing spring 7, which is weaker than spring 11, thereby absorbing the pressure peak and storing the excess fluid volume incapable of immediate discharge through orifice 12 resulting ina prolonged discharge of the fluid. Since the pumping cycle is rapid, the ink stored by ball 6 is replenished before the previously charged quantity in chamber 5 is exhausted thereby the flow from the orifice is a smooth continuous flow of ink.

Theelectric pulses which energize coil 9 are generated by apparatus depicted in FIGURE 5 and communicated to coils 9 by cables coupled together at connector 13 shown in FIGURE 2. The volume being discharged may beregulated by either of two means. The first of which is illustrated in FIGURE 2 and provides direct at the pump control. The control consists of adjusting screw 14 which is made to include the excursion limit rod 10 and thereby regulates the travel or stroke of ball 8. The adjusting screw 14 is provided with graduations to facilitate resetting and relative adjustment. The second means of volumetric control is disclosed under the heading of controls.

a, 9 Fluid Supply Change Ink dispensing devices employed heretofore have immersed the working mechanism in the ink supply which is being dispensed and have the ink sumps integrally constructed with the dispensing means. Naturally, this necessitates removal of the fluid being fed and a thorough cleaning of the entire mechanism whenever an ink change is made. This procedure has limited the application of color printing and the flexibility of color printing due to the time and expense involved to clean the ink feed machinery.

Referring to FIGURE 2 in the present invention the ink supply sump 18 comprises a portable container with a shut olf valve 16 in the passage which provides egress of the ink to the fluid feeding elements. Said container 15 is provided with suitable fastening and locking lugs 17, 18 and 19 to secure the container 15 to the fluid feeding mechanisms structure. The small volume of fluid in the pumping channel may be rapidly removed by pumping a cleaner fluid or solvent from another supply sump for a short period of time prior to installation of the new fluid or ink supply.

When the pump is so employed it applies solvent or cleaning fluid to the ink motion of the press while purging the pumping channel; said application of cleaning fluid to the ink motion assisting in washing up operations of the ink motion which are required prior to inking up with the new ink color. Fluid supply sumps are removed by moving shut ofi. valve 16 laterally closing the fluid egresses at the bottom of the sump, removing the clamping screws 1% and lifting the supply sump from the pumping mechanisms structure. Another sump may then be fastened to the pumping mechanism with screws 19 and the fluid passage from the sump to the pumping elements opened by shifting the valve 16 laterally. Thus color ink and dilferent fluid may be dispensed to perferred locations of the ink motions and color printing may be rapidly and economically achieved at any desired part of the printed page or copy.

The ink supply sump has been devised to accept the installations of partitions dividing the sump into a plurality of smaller sumps supplying one or more pumping elements at adjacent pump egress orifices.

In some press room installations it is found desirable to employ centralized ink color supply tanks. The present invention as illustrated in FIGURE 6 with the addition of ink color selector valves 20 provides plants with centralized ink sumps a means to change ink color without the cleaning of the fluid dispensing mechanism or the alternate employment of auxiliary ink feeding devices; Referring to FIG. 7, multiple centralized ink supply sumps, 65A, 65B, 65C 65:1, are provided with a pumping means 64A, 64B, 64C 6% to cause the fluid to flow to the distribution rail 21, as depicted in FIGURE 7, said rail having a plurality of closed channels extending across the press width and at right angles to the plurality of fluid pumping and apportioning elements wherein each channel provides a possible communication from the centralized supply to the fluid dispensing elements for that particular fluid. The aforementioned valve 24) is so constructed as to maintain all ink supplies closed, by the blocking action of valve spool 22, except the one fluid to be dispensed. Selection of the fluid to be dispensed is accomplished by axially positioning the valve spool 22, which is shown as manually positioned in FIGURE 6 but may be remotely positioned by electrical solenoid or pneumatic means. As the spool 22 is moved from position to position it interconnects a different supply to the pumping elements and block all the remaining fluid supplies. 7

In FIGURE 7, the valve spool 22 is illustrated as remotely positioned by a position servo arrangement in which 61 is the output servo motor displacing the spool 22 in accordance with a command signal generated by 62 the servo generator. The command signal is selectably set by rotation of the input handwheel 63.

Pulse Generator When the present invention is applied to the ink motion of a printing press it is necessary to feed ink in proportion to the presss operating speed, as well as the requirements established by the image being reproduced. Since the pumping elements, as depicted, are actuated by the passage of a pulse of electrical energy; the pulse generator, which may drive a number of fluid dispensing and apportioning units, consists of a series of energy interrupting devices, which will be referred to as switches, with the switch actuating means driven at a rate proportional to the presss operating speed; This may be accomplished by connecting the switch cam shaft 41 to the press drive shaft. The cam shaft 41 carries a number of cams 42 which have differing numbers of lobes such that the first cam 42 a actuates switch 441%: once per revolution; cam 42b actuating switch 49b twice per revolution and so on, the last switch dun which produces the maximum number of pulses required, per press revolution. In applications requiring one or only a few fluid dispensing units the energy pulses developed by interrupting the power source supply may directly actuate the dispensing units; however, in larger installations the switches are connected to power amplifiers, say of, thyratron type, and said amplifying devices 43 feed power to the control circuit and fluid dispensing means. The entire power generator is depicted in FIGURE 4 by character 32.

Controls and Their Operation The control of the fluid dispensing and apportioning elements may be located at any convenient and desirable 10- cation, such as the presss folder or the quality control office. Referring to FIGURE 4 each electromagnetic field producing coil 9 is connected in series with disconnect switches 34 and 33 and with multiple circuit selector devices 31, which are illustrated as multi position contact switches but may embody inductive and other circuit connecting or control means, and also with the multi circuit selector transfer device 35 and thence to the pulse generator 32. As depicted, each coil 9 is associated with an individual circuit selector 31 to permit the selection of the desired number of pulses per press revolution. The individual coils are grouped into sets and connected to continuity switch 33; such that each switch 33 controls a set of coils 9. The function of switch 33 is to provide group shut off of a plurality of fluid dispensing means. In current practice on printing presses the shut ofl of a page; which is coincident with shutting off a set of fluid dispensing elements in the present invention, usually necessitates the employment of special ink cut off blades, relieved periphery ductors and/or readjustment of blade (and therefore ink adjustment) control means. The switch 34 provides for a printing unit shut down as occurs on multi unit publication presses as the page capacity of the publication varies from issue to issue.

On printing images, particularly in multicolor work it is not necessary to dspense ink the full width of the web since a color may occur only in some local columns of the web width, therefore, the selector switch 31 is provided with a non connecting position 36 to provide individual column shut oif when required. As shown in FIGURE 4 the web width of a printing units ink control is divided into page wide sets of fluid dispensing elements each set capable of collective shut otf and each individual capable of individual adjustment for ink apportioning and shut off.

It often occurs that the volume of ink apportioned to a Web will need to be varied due to the slight difference of the paper stock from roll to roll. It also ocurs that the setting of an image, or page width is properly adjusted for the column apportionment relative to each other but that the group or set of fluid dispensing elements need to be collectively adjusted to apportion a larger, or smaller volume of fluid to produce the proper density of reproduction of the image. Switch 35 has been provided for this purpose. As shown in FIGURE 4 the switch 35 is located in the circuit to reassociate the Circuits from the pulse generator 32 to the individual selector switches 31, such that the circuit from the generator with one pulse may be reassociated to a selector switch position of say two pulses, thereby reducing-the number of pulses communicated to the associated coil. Since all the pulse circuits are connected thru the switch 35 to the associated selector switch positions and since all the poles of the switch 35 are transfered together by the switch 35 the pulses distributed to the various switches are increased, or decreased by the same amount. That is, with the pulses connected in consecutive order; if the coil 9a was set at position 2 (pulses) with switch 31a and coil 9b was set at position 5 (pulses) by selector switch 31b and so on; then adjusting the transfer switch 35 from say position 1 (pulse) to say 2 (pulse) the pulses distributed to coil 9a would be 3 and to coil 9b would be 6.

-T he FIGURE 4 shows one transfer switch 35 controlling the collective operation of sets of coils, as for web width control; it is clear that a switch 35 may be provided for each set of coils and thereby provide page collective control.

Since each pulse causes a measured volume of ink to be dispensed; the tuning in on multiple pulse circuits necessarily apportions a fluid discharge, per press revolution, proportionate to the multiple of the basic unit volume discharged by a single pulse.

' Therefore, if the maximum volume to be discharged is divided by, say 10, and this volume is made equal to the basic single pulse fluid dispensement (this may be set by adjusting the pistons 8 excursion with limit rod 16 for the basic volume), then the apportionment of fluid is controlled by the remote selectors for the desired pulse count and apportionment.

Alternate construction of the pumping element is shown in FIGURE 6 with adaptation for centralized ink and fluid supply. The pumping means is as described above but the components have been altered as follows. The piston 38 is driven by the spring 47 toward the abutment of the adjusting screw 48 reducing the pressure in the second chamber and drawing fluid past valve 49 into said chamber. With the occurrence of an energy pulse the coil- 39 drives the piston 38 against the spring 47 forcing the fluid out of chamber 52 thru valve 56) and into chamber 53whence said fluid is dispensed thru the orifice 54. Chamber 53 is provided with a resilient portion 55 in its wall to absorb the volumetric pulsations and to filter such into a smooth flow thru the orifice 54. In this configuration of the present invention the fluid selected by the positioning of valve spool 22 enters the pumps first chamber from the bottom of the pump and is forced out the orifice by the electromagnetic fields energy.

While the discussion has been presented as applied to the ink motion of a printing press this is not intended to limit the invention in any manner since the advantages and benefits of the invention may be equally realized when dispensing other fluids and semi-fluids, i.e. fluid containing fine suspensions, as in the case of adhesives, coatings, and other chemical solutions dispensed in precisely regulated quantities, etc.

It is clear the present invention affords simple and complete remote control of fluid dispensement and apportioning with dispensing elements, or units, which may be remotely located from each other and their control means.
