Definitions

  • ABSTRACT For delivery of cleansing liquid to printing rollers, a collapsible chamber is incompletely filled with a liquid which is thereafter delivered directly to spray nozzles by compression of the chamber. Reexpansion of the chamber draws in a new charge of liquid and concurrently withdraws residual liquid from the spray orifices to prevent dripping on the cleaned printing rollers.
  • a two chamber system is disclosed in which a new charge of cleaning liquid is received in and metered by a first chamber for subsequent transfer to the second chamber.
  • This invention relates to a fluid dispensing system and more particularly to liquid dispensing apparatus which is especially adapted for use as a cleansing accessory for the ink-bearing rolls of a printing press.
  • one specifically described control arrangement comprises an air-actuated bellows which in the air-on condition channels pressurized solvent to the nozzle valves, forcing them open, and which, in the air-off" condition, terminates the flow of solvent and at the same time relieves pressure in the nozzle supply line sufficiently to permit the individual nozzle valves to close.
  • the present invention solves this residual problem by providing means by which, at the end of each solvent supplying cycle, a negative pressure" is developed at the supply line side of each spraying orifice, thus drawing back into the orifice (and eventually into the supply line) any lingering quantities of solvent which may occupy or surround the orifice opening.
  • this result is accomplished by the provision of a fluid dispensing system in which both the positive pressure needed to accomplish spraying action and the negative pressure needed to draw back into the system residual orifice droplets are produced directly by on-off control of a supply of pressurized solvent.
  • FIG. 1 is a view, partly in true cross-section and partly schematic, of a fluid dispensing system in accordance with the invention
  • FIG. 2 is a sectional view of the principal functional elements of FIG. 1 shown in an altered operating condition
  • FIG. 3 is a schematic representation of an exemplary control circuit for use with the system of FIG. 1.
  • FIG. 1 there is shown schematically a liquid dispensing system which comprises a source 10 of pressurized liquid and, at the right hand end of the Figure, an outlet nozzle 15 having an orifice through which liquid from the source is desired to be projected in a controllable fashion.
  • the liquid source 10 may comprise a tank of cleansing solvent (for example, a petrochemical derivative) which is maintained under pressure as by a compressed air source (not shown) associated with the tank.
  • the nozzle 15 may be one of several similar nozzles connecting with a manifold 17. This manifold, which is shown in section, may be assumed to have considerable extension in its axial direction and to carry along its length of series of spaced nozzles corresponding in form and function to the nozzle 15.
  • a segment 20 of what may be taken to be an inking roller In proximity to the nozzle 15 there is shown in end view a segment 20 of what may be taken to be an inking roller. As will be readily understood, such a roller in its normal usage tends to acquire surface accumulations of ink which must be removed from time to time by a cleansing operation. In this context it is the function of the nozzle 15 (and of the similar additional nozzles associated with the manifold 17) to spray a cleansing solvent on the roller surface at times and during periods which may be selected by the operator of the printing equipment. In connection with the roller 20 there is further shown a wiping blade 25 which, under the control of the equipment operator, may be moved into contact with the surface of the roller in order to scrape from it the mixture of solvent and dissolved ink which results from a spraying operation.
  • FIG. 1 a new form Of flow control apparatus which is to be interposed in the conduit system extending between the source and the spray orifice a for controlling the fiow of liquid through the conduit system in a fashion which will eliminate the drippage difficulty just referred to.
  • the flow control apparatus employed by the present invention comprises the combination of means for alternatively establishing fiow of liquid from the source 10 to a conduit portion 30 which connects with the manifold 17 and through the manifold with the nozzle 15 and secondly, under control of an appropriate cycling device, interrupting such flow after a desired time interval.
  • negative pressure is here used in the broadest sense to mean not only a pressure which is sufficiently below atmospheric pressure to produce in-draft of air through the nozzle orifice but also any pressure which is reduced sufficiently below a pre-existing pressure to induce or permit positive inflow of fluid through the spray orifice whether under the influence of air pressure, gravity or otherwise).
  • control means described generally in the preceding paragraph comprises a coupled piston as sembly designated generally by the numeral 35.
  • This assembly is shown in longitudinal cross-section, but as seen end-on, would appear as of generally cylindrical configuration.
  • it includes disk-like end plates 37 and 38 which are joined by a set of symmetrically disposed tie rods 40, of which only two are shown.
  • Compressively retained between the end plates in end-toend relation are a first cylinder 42 and a second cylinder 44, the latter being of significantly larger diameter than the former.
  • the cylinders 42 and 44 are separated at their most nearly abutting extremities by a circular plate 46 upon which each cylinder bears circularly as indicated at 48 and 50, respectively.
  • a smaller piston-forming cylinder 52 Centrally disposed within the cylinder 42 there is a smaller piston-forming cylinder 52 which terminates at its left hand in a circular cylinder head 54. Extending across the outer surface of the cylinder head is flexible roll-up diaphragm 56 which may consist of fabric having a solventresistant impregnation and the function of which will be further described at a later point.
  • diaphragm S6 extends across the head of the piston then loops back upon itself in the annular space provided between the cylinders 42 and 52 as indicated at 56a. It terminates peripherally in an enlarged bead 56b which is compressively retained between the end plate 37 and an annular ring 58 which also provides a centering retaining means for the cylinder 42.
  • a circular cover plate 60 which has a screw threaded attachment 62 to other parts of the piston structure compressively engages the central area of the diaphragm 56, holding it firmly against the outer surface of the cylinder head 54.
  • the space between the end plate 37 and the facing surface of the diaphragm 56 provides a collapsible (and extensible) chamber, the volume of which may be varied by movement of the piston cylinder 52 for purposes subsequently to be described.
  • a connecting rod 65 which is secured to the cylinder end wall 54 by means of the threaded screw 62.
  • This connecting rod extends through the dividing wall 46, being slidably supported in the central portion of that wall by means of a bushing 70.
  • the connecting rod occupies an axial position within a second piston cylinder 75, which is terminated at its right hand end by a cylinder head held in place by attachment to the abutting extremity of the connecting rod 65.
  • Attached to the outer surface of the cylinder head is a flexible roll-up diaphragm 83 which in turn is clamped against the cylinder head by a circular cover plate 84 held in place by the screw threaded member 86.
  • the diaphragm 83 is similar in construction to the diaphragm 56, previously described, and, like that diaphragm, terminates at its peripheral edge in an enlarged beaded portion 83b. As shown, this beaded portion is held against the circular end wall 38 by a grooved clamping ring 90. The entire structure as so far described is held in demountable assembly by the tie rods 40, previously referred to.
  • the end plate 37 has an inletoutlet port by which liquid may be admitted to and withdrawn from the otherwise generally sealed space bounded by the flexible diaphragm 56.
  • the opposite end wall 38 has an inlet-outlet port 99 by which liquid may be admitted to and withdrawn from the space bounded by the second diaphragm 83. It is also important at this point to note that the volumetric space contained within the diaphragm 83 in the fully expanded condition in which it is shown in FIG. 1, significantly exceeds the corresponding volumetric space within the diaphragm 56 in the fully expanded condition in which it is shown in FIG. 2.
  • chamber B provides a connection between the port 95 which communicates with the interior of diaphragm 56 and port 99 which communicates with the interior of diaphragm 83.
  • This connection is created by a conduit system which includes a tubular connection extending between the port 95 to a port 122 in valve chamber B, thence through port 124 in valve chamber B to a further tubulation 126 which connects at its opposite extremity 126a with port 99 formed in end wall 38. It needs to be observed at this point for further reference at a later stage that the tubulation 126 also has a direct connection through the branch tubulation 30 with the mainfold 17 and through this and through the connecting nozzle 15 with the orifice 15a out of which solvent liquid is eventually to be projected.
  • valve cylinder ll0b will be drawn to the right by the solenoid, as shown in FIG. 2, and the ports 145 and 146 of valve chamber A will establish direct connection between tubulation a leading from the pressurized liquid source 10 and tubulation 120 leading to the port 95 which communicates with the interior of the diaphragm 56.
  • the left hand end of the tubulation 126 will be cut off from communication with tubulation 120.
  • pressurized liquid will enter the space bounded by the diaphragm 56 and, in due course, will move the piston cylinder 52 into the position which it is shown to occupy in FIG. 2.
  • tubulation segment 1260 the body of liquid solvent 130 shown in FIG. 1 as being enclosed by the diaphragm 83.
  • tubulation 126 since tubulation 126 is now closed at its left hand end (see FIG. 2) this liquid will necessarily be projected into the manifold 17 and thence through the nozzle and the orifice 15a. The resulting spraying action will continue until the stored liquid has been entirely expelled, or, in any event until the piston cover plate 84 reaches the limiting abutment 160.
  • a metered quantity of cleansing fluid is projected onto the surface of the inking roller 20 whence it will in due course be removed (along with dissolved ink) by action of the wiping blade 25.
  • the fluid control apparatus will be caused to perform its various operating functions a number of times during any given cleaning operation although this is not necessary for the useful application of the present invention.
  • the present invention contemplates that any given cycle will be terminated by de-energizing the solenoid coil 139, thus permitting the tension spring 135 to return the twochambered valve cylinder 1 10b to the position which it occupies in FIG. 1. Under these circumstances, the valve ports 122 and 124 will again be opened, thus directly interconnecting the openings 99 and through the tubular connections and 126.
  • the opening 95 will be disconnected from the pressurized liquid source 10. Because of the last-mentioned circumstance, the compression spring 150, acting within the piston cylinder 52, will be effective to move that cylinder to the left, thus compressing the diaphragm 56.
  • the cleansing liquid b contained within the diaphragm-enclosed space will, as a first result, be forced through the tubular connections 120, 126, and 126a and thence through the opening 99 into the chamber enclosed by the diaphragm 83 at the right hand end of the control apparatus. Because, as has been previously explained, this chamber is significantly larger than the corresponding chamber enclosed by the diaphragm 56, the full expansion of diaphragm 83 (i.e. to the position shown in FIG.
  • the present invention is still useful in that the mere lessening of the volume of liquid contained in by the tubular portions 126 and 126a which is inherently accomplished by the invention will facilitate, by syphon effect and otherwise, the withdrawal of excess fluid from the vicinity of the orifice.
  • FIGS. 1 and 2 has a special advantage in that a single pressurized fluid (i.e. the cleansing solvent itself) serves both as the means for compressing the piston represented by the cylinder 52 and for supplying solvent to the spray nozzle manifold 17. It will be understood, however, that, if desired for any reason, a separate source of energization of the piston cylinder 52 may be employed, such, for example, as a valve-controlled stream of pressurized air or other fluid medium. From this point of view, a primary requirement of the present invention is that the volume of the chamber represented by the fully expanded diaphragm 83 must be greater than the volume of solvent introduced into the conduit system when the diaphragm is compressed.
  • the rod-end and head-end chambers of a typical double-acting piston cylinder in which the maximum rod-end volume is necessarily less than the maximum head-end volume by virtue of the space deducted from the former by the body of the rod itself.
  • the action of the spring 150 will be to drive the measured quantity of solvent initially contained within the dia phragm 56 through the tubulations 120, 126 and 126a and through the wall opening 99 into the relatively large chamber in the process of being formed by the expanded diaphragm 83.
  • the partially filled condition of this chamber represented in FIG. 1 will be restored, the quantity of liquid received in the chamber being metered" in accordance with the dimensions of the diaphragm 56.
  • FIG. 3 An exemplary timing mechanism is pictured diagrammatically in FIG. 3.
  • the terminals 140 of the solenoid coil 339 (FIG. 1] are shown as being connected to an eiectrical power source 180, the application of which is controlled by a switch 185. Closure of this switch initiates rotation of a low speed motor 190 which, in turn, rotates a con tact-bearing wheel 200.
  • Electrically conductive members 205 spaced around the periphery of this wheel serve intermittently to interconnect conductors 210 and H5, thus cyclically energizing the coil 139. Any desired timing of the on and off portions of the switching cycle can be provided by appropriate spacing and dimensions of the contacts 205 and/or the speed of rotation of the output shaft of the motor 190.
  • the switch 185 may also be electronically controlled to interlock the operation of the spraying mechanism with the apparatus which controls the rotation of the roller and the action of the wiping blade 25.
  • a liquid dispensing system of the type which includes a source of liquid, an orifice through which such liquid is to be projected, and a conduit system extending between said source and said orifice for establishing a liquid-bearing connection between them to convey washing liquid to the press parts to be washed
  • a liquid dispensing system of the type which includes a source of liquid, an orifice through which such liquid is to be projected, and a conduit system extending between said source and said orifice for establishing a liquid-bearing connection between them to convey washing liquid to the press parts to be washed
  • control apparatus to be interposed in the conduit system, such apparatus comprising, 1. a first expansible and collapsible chamber for alternatively a. establishing flow of liquid from the source to the portion of the conduit system which connects with the orifice when said chamber is collapsed, and
  • a second expansible and collapsible smaller chamber inter-connected to said first chamber to operate in opposite expanding or collapsing phase thereto, and being connected to the conduit system through said valve when said valve interrupts flow from said first chamber and effective upon such interruption of flow to establish a negative pressure within the portion of the conduit system which connects with the orifice, thereby to withdraw residual liquid from the orifice.
  • a liquid dispensing system of the type which includes a source of liquid, an orifice through which such liquid is to be projected, and a conduit system extending between said source and said orifice for establishing a liquid-bearing connecting between then;
  • control apparatus to be interposed in the conduit system, such apparatus comprising 1. means for establishing flow of liquid from said source to a portion of the conduit system which connects with the orifice and for subsequently interrupting such flow, such means including a. an expansible and collapsible chamber,
  • Control apparatus in which the said means for progressively collapsing the said chamber comprises:
  • control means for admitting to the second chamber pressurized fluid for expanding that chamber.
