Definitions

  • the ink and water form rollers in such a press are subjected to throw-off whereby the form rollers are moved to a position spaced from the periphery of the plate cylinder. It is desirable that these form rollers subsequent- 1y return to the same precise relationship with the plate cylinder regardless of its condition of skew in order to provide uniform and even distribution of water and ink. While complex linkages may be employed between the form rollers and the plate cylinder to aline the same after skewing the plate cylinder, it will be appreciated that such complex linkages and other mechanisms having delicate adjustments may in time develop a looseness or a play due to wear and vibration and thereby may not achieve the desired contact between the form rollers and the plate cylinder.
  • a general object of the present invention is to provide a mounting arrangement for a plate cylinder and associated form rollers in a printing press which is economical in construction and which assures more ac curate and reproducible positioning of a form roller than has been afforded by prior mounting arrangements.
  • Another object of the invention is to provide a mounting arrangement of the above type which is capable of accurate and consistent operation over a long period of time and which avoids complicated linkages that may, as a result of useage, develop looseness or play.
  • a more specific object of the invention is to mount the form rollers on mounting plates biased against a reference ring coupled to the plate cylinder so that the form rollers follow the skewing movement of the plate cylinder and maintain an even and parallel relationship with the printing cylinder in all of its possible positions of adjustment.
  • a further object of the invention is to provide a mechanism in such a press capable of automatic return of a form roller to an unaltered relationship with a skewed plate cylinder following throw-oil.
  • FIGURE 1 is a fragmentary elevational view, somewhat diagrammatic, of a printing press for carrying out the invention
  • FIG. 2 is an enlarged, fragmentary setcional view taken along the line 2-2 of FIG. 1 in the direction of the arrows and showing the mounting of the opposite end of the plate cylinder in the frame of the press;
  • FIG. 3 is a fragmentary sectional View of a side elevation of the printing press, with the side frame removed and with portions broken away to show the relationship of the various form rollers with the printing plate cylinder;
  • FIG. 4 is a partial sectional view taken along the line 4-4 of FIG. 3 showing the mounting of an ink form roller as related to a ring carried by the plate cylinder;
  • FIG. 5 is a partial sectional view taken along the line 5-5 of FIG. 3 and showing the relationship of the form roller to an ink drum and its mounting plate;
  • FIG. 6 is a partial sectional view taken along the line 6-6 of FIG. 3 and showing the connection of a throw-off cylinder and the mounting plate for the ink form rollers.
  • the invention will be shown and described as used on units of offset printing presses of the perfecting type.
  • the paper web runs between two co-acting blanket cylinders, and the ink impression or image carried on either cylinder is imprinted simultaneously on both sides of the web.
  • Presses for printing a high quality product of several colors may consist of several units in a line with the web running consecutively through each unit which applies a specific color thereon. It is necessary for the imprint of each color to be placed on the web precisely in register with the imprints of other colors, so that the final product will be a sharp and true reproduction of the original copy. It sometimes happens that errors are made in preparing or mounting the printing plate or that the cylinders of successive press units are not precisely parallel. When a cylinder is adjusted to compensate it affects the relationship of the associated members which must be correspondingly adjusted to maintain the proper cooperative relationship between them.
  • FIG. 1 of the drawings illustrates diagrammatically the structure used in practicing the invention as embodied in the lower half of a unit of a press 10 in which both sides of a web are printed simultaneously.
  • the web W passes between blanket cylinders 11 and 12 which apply the ink images to the web.
  • the blanket cylinders run in contact with the plate cylinders 13, 14 and receive the inked images from plates held on the plate cylinders by suitable grippers.
  • the plates are moistened and then a film of ink of desired color is applied to the receptive areas in accordance with the usual practice followed in offset printing.
  • a pair of side frames 15, provides support for the various elements in proper relation to carry out the printing operation or to perform other functions which will be described in the following paragraphs.
  • Flange members 15a formed at right angles to the side frames provide structural reinforcement.
  • Ink is supplied by an ink fountain, designated generally as 18, from which it is dispensed in regulated amount to a series of rollers designated generally at 16,
  • Form rollers 26, 27, 29, 30 are interposed between drums 23, 24 and plate cylinders 14, and are adjusted to uniform longitudinal contact and desired pressure for application i of ink to the printing plate.
  • a special mounting is provided for the ink form rollers and it is this mounting which comprises part of the invention for maintaining alinement of these rollers with the plate cylinder.
  • a moistening arrangement shown generally at 17 is used, including a shallow pan or mountain 28 and a fountain roller 28a.
  • the roller transfers moisture to drum 31 which in turn contacts form roller 32 which rolls on the the surface of the plate. It is important that the liquid be applied uniformly over the entire surface of the printing plate and consequently form roller 32 is adjustably mounted so that it can be set against the plate with uniform longitudinal contact at desired pressure.
  • the mounting which will be described includes means for maintaining alinement of the axis of the form roller with the axis of the plate cylinder.
  • the supporting shaft or journal 34 for plate cylinder 14 is rotatably supported by a bearing 35, which is mounted in a sleeve or bushing 36 received in a bore 37 in side frame for limited rocking movement.
  • the bore of bushing 36 is eccentric to its outer surface so that axis 19 of plate cylinder 14 is slightly offset from the center of bore 37.
  • Circular plate 54 bolted to the end of shaft 34 serves as a retainer for hearing 35.
  • a cover plate 38 is securely fastened to the end of the bushing.
  • an integral arm 39 coupled to a connector 64 by a pin 65.
  • the connector is secured to the end of a thrust rod 62.
  • the outer end of the rod is also threaded for reception in a captive nut 63 which is rotatably mounted in the flange 15a of the side frame and which is coupled to a handwheel 61. Rotation of the handwheel resulting in axial movement of the rod 62 rotates the eccentric bushing 36 to a desired angular position, shifting the end of axis 19 of plate cylinder 14 'to a slightly skewed position.
  • the handwheel may be turned in either direction and in practice a correction of up to 0.015 inch can be made in the position of certain areas of the image printed on the web.
  • the small skewing movement is within the tolerance of the bearing 35, so it is not necessary to provide any realinement of this bearing.
  • the present invention contemplates a novel and simplified arrangement for causing the form rollers, such as the ink form rollers 26 and 27, to closely follow the skewing movement of plate cylinder 14 and thus to maintain parallelism and uniform contact with the plate cylinder.
  • a reference ring 75 having an outside diameter the same as that of the plates on the plate cylinder 14-, is attached to bushing 36 so that its axis coincides with the axis 19 of the plate cylinder and so that its outer surface 78 is always in alinement with the surface of the plates.
  • the outer surface of the ring moving whenever the bushing is turned, thus becomes a reference for the surface of the plates for all positions of the plate cylinder.
  • the sockets of the respective form rollers are supported in mounting plates which are pivotally mounted about the shaft 68 of ink drum 23. As shown in FIG. 5, the socket 42 which supports the form roller 26 is attached to a plate 40 on one side of the drum axis.
  • a plate extension or arm 83 on the other side of the drum axis is engaged by suitable biasing means for holding the end of the plate 87 in contact with surface 78 of ring 75, permitting the mounting plate to rock about the shaft of the drum and carry the end of the form roller with it, when it is necessary to skew the axis of the plate cylinder to obtain registration of the printed image on the Web.
  • Adjustable mounting for the form rollers also provided at the opposite ends except that at the opposite ends the mounting plates engage fixed stops and thus remain relatively stationary as the plate cylinder is skewed; consequently it is not necessary that the opposite ends of the rollers be shown or described in detail.
  • rollers are mounted similarly to roller 26.
  • form roller 27 is supported on a plate 41 which is pivotally mounted on the shaft 68 of ink drum 23, while rollers 29, 30 are supported on plates 40a, 41a which are pivotally mounted on the shaft 68a of ink drum 24.
  • Bushings indicated at 79, and 790 may be interposed between the mounting plates and the drum shafts on which they are mounted.
  • Such shafts are in turn rotatably supported in the frame by bushings 73 (see FIG. 5).
  • the mounting plates are biased into engagement with ring 75 at 87, 88 and contact is maintained by means of suitable springs 85, 86, which bear against arms 83, 84 of the mounting plates.
  • FIG. 6 shows a shaft 93 supported by bushing 25 in frame 15.
  • the shaft extends to the frame on the opposite side where it is similarly mounted and provides a fixed base for creating the biasing force to maintain contact between plates and ring 75.
  • This shaft 93 also supports a double throw eccentric or cam 74 by means of which the form rollers can be bodily separated from the plate cylinder 14 when required during operation of the press.
  • FIGS. 3 and 6 Details of the mechanism being shown at 69 and 70 in FIG. 6.
  • the arm 83 on the mounting plate 40 is bifurcated and fitted with a special pin 33.
  • This pin has flat sides at the center but is cylindrical at the ends so it can turn between the two parts 57, 58 with respect to the arm 83.
  • a hole is drilled at right angles through the flat of this pin.
  • a stud 71 passes through this hole and is threaded into the elongated portion of a strap fitting 72 that is rotatably fitted to the eccentric 74 on shaft 93.
  • a bushing 76 surrounding the stud is pressed by the spring 85 and engages one of the flat sides of pin 33 as shown in FIG.
  • bushing 76 Telescoped within the bushing 76 is a second bushing 77 which engages the opposite end of the spring.
  • Spring member 85 is thus contained between the flanges of bushings 76 and 77.
  • a nut 80 is threaded onto the outer end of stud 71 and serves as a means for adjusting the position of bushing 77 and hence the force exerted by the spring.
  • the biasing force of spring 85 urges bushing 76 into engagement with the flat on pin 33 which in turn is secured in arm 83 of mounting plate 40, tending to rotate the plate in a clockwise direction as shown in FIG. 3, holding it resiliently in contact with ring 75 at the region 87.
  • Springs 85, 86 are separately adjustable.
  • Means are provided to permit adjustment of the roller sockets with respect to their mounting plates thereby to permit adjustment of the set of the roller with respect to the plate cylinder 14 and ink drum 23.
  • FIGS. 4 and 5 show the construction of the sockets 42 at the ends of the form rollers.
  • the bearings 46 on the shafts 47 at the end of form rollers 26 and 27 are secured in housings which in turn are attached to adjustable brackets 48 which are adjustably positioned on mounting plates 40, 41.
  • Bracket 48 is held against the mounting plate by a nut 52 on a stud 50 which extends through a clearance opening 51 in the bracket terminating in a head member 49.
  • bracket 48 may be shifted as required to make necessary adjustments of the form roller. As shown in FIG.
  • the mechanism shown includes means for producing this separation and also for moving the form rollers back into contact with the plate cylinder, without affecting the setting or alinement of the rollers.
  • Independent controls are provided so that ink form rollers may be separated at one time and the water form roller separated at a different time.
  • the throw-off operation may be performed when the plate cylinder is in alinement or when it is in a skewed position. In prior structures it has been ditficult to regain accurate alinement between form rollers and a plate cylinder following a throw-off operation, when the form rollers were returned into contact with the plate cylinder.
  • the disclosed arrangement eliminates this diificulty, because the mounting plates will always return to engagement with the surface 78 of ring 75, which is equivalent to the plate cylinder surface, thus assuring automatic realinement of form rollers and plate cylinders.
  • Throw-off of the ink form rollers is here accomplished by a power cylinder 96, which is connected to a lever 92 on a throw-off shaft 93.
  • Plunger 91 of cylinder is actuated by movement of a piston within the cylinder and may be moved in or out as desired by applying pressure fluid to the appropriate end of the cylinder. This arrangement is shown in FIG. 1 while details of the mechanism will be found in FIGS. 3 and 6.
  • a double-throw cam 74 with the throws positioned approximately 180 degrees apart, is keyed to shaft '93.
  • the strap fittings 72 for connecting the plates with the means for biasing the plates against the ring 75 are fitted on to the cams so that assembly 69 is opposite to assembly 70.
  • cam action results in separating the arms 83, 84 on plates 41), 41 or drawing them closer together.
  • a movement of cam shaft 93 will result in clockwise rotation of plate 41 and counterclockwise rotation of plate 40, breaking contact at 87, 85.
  • carn shaft 93 extends entirely across the press and actuates mechanism on the opposite side of the press which is similar to that shown, so that throw-off occurs equally at both ends of the form rollers.
  • the actuating cylinder 90 is actuated to rotate the cam shaft 93 back t its starting position re-establishing contact with the surface of ring 75 at 87 and 88, thus restoring the original alinernent or set.
  • ink is applied to the printing plate by pairs of form rollers each in contact with a drum
  • moisture is applied to the surface of the printing plate by the single water form roller 32 as shown in FIGS. 1 and 3.
  • Maintenance of alinement of this form roller with the plate cylinder while in slightly skewed position is similar to the arrangement 42 described above, and is obtained by ad justably mounting the form roller 32 in a socket 142 attached to plate 144 which is pivotally supported on the shaft 168 of drum 31.
  • An arrangement 169 similar to 69 which applies a biasing force to plate 41, is attached to strap fitting 172, biasing plate against the ring 75 at point 187. Throw-off of the form roller 32 may be actuated by power means 190 (FIG.
  • the cover plate 38 which is secured to the eccentric sleeve 36, has an integral stub shaft 154 which extends axially outward and which is threaded, preferably with a thrust-transmitting thread of acme configuration.
  • the stub shaft is engaged by an internally threaded worm wheel 155 driven by a worm 156 which, in turn, rotated by an adjusting drive motor 157. Rotating the motor in one direction or the other causes the eccentric sleeve 36 in which the shaft of the cylinder is captive, to be moved in opposite directions.
  • the same eccentric sleeve assembly is capable of bringing about two distinct types of adjustment, namely, the skewed shifting of the printing cylinder and the associated form rollers via the ring 75 and the endwise shifting of the printing cylinder by means of the threaded stub shaft 154.
  • mounting plates has been applied to the mounting members for the form rollers, such as that shown at 40, the members may take any desired physical shape consistent with their pivoted supporting function.
  • a printing press comprising a pair of spaced side frames, a cylinder for holding printing plates, means for journalling the cylinder in said frames, said journalling means including means at one end for laterally shifting the cylinder axis for skewing adjustment, an ink drum journalled in said frames and radially spaced from the plate cylinder, a form roller disposed for rolling engagement with said cylinder and said drum, a mounting plate supporting one end of the form roller and pivoted for swinging movement substantially about the drum axis, a reference ring at said one end of the cylinder coaxial with the cylinder and coupled to the cylinder to maintain the coaxial relationship in all positions of skew, and means for maintaining the form roller mounting plate in engagement with the ring so that the form roller follows the cylinder over its range of skewing adjustment.
  • throwotf means for rotating the mounting plate in a first direction to separate the plate from said reference ring and said form roller from said cylinder and for rotating said plate in a reverse direction to re-engage said plate with said ring and said form roller with said cylinder.
  • a printing press comprising a pair of spaced side frames, a cylinder for holding printing plates, means for journalling the cylinder in said side frames, said journalling means including means at one end of the cylinder for laterally shifting the cylinder axis for skewing adjustment, a plurality of ink drums journalled in said frames and radially spaced from the plate cylinder, form rollers interposed between the ink drums and the plate cylinder, each form roller having a mounting plate supporting one end thereof and pivoted for swinging movement substantially about the axis of the associated ink drum, a reference ring at one end of the cylinder coaxial with the cylinder and coupled to the cylinder for maintaining the coaxial relationship in all positions of skew, means for biasing the mounting plates against the reference ring to establish axial alinement of form rollers and cylinder so that the form rollers follow the skewing movement of the cylinder and maintain uniform contact with the plates thereon over the range of skew adjustment, and means for simultaneously swinging the roller mounting plates in a direction
