Definitions

  • the invention relates to an inking unit for use in a printing press with a working doctor blade which can be set on an anilox roller and an ink tray with inking means.
  • An inking unit of this type known from the magazine "Der Polygraph" 13-88, page 1103, has separate holders for the working doctor blade forming part of a chambered doctor blade on the one hand and the ink tray with the ink conveying means on the other hand. Apart from the fact that two brackets are required, the chamber doctor and the ink tray must be removed one after the other with each color change. Then another chamber squeegee and ink tray must also be reattached separately.
  • the US Pat. No. 3,500,745 shows an inking unit in which a feed roller including a doctor blade and an ink tray are combined to form an exchangeable structural unit.
  • the feed roller is detachably connected to a drive shaft parallel to it via drive gears.
  • the invention has for its object to provide a structurally simple arrangement that minimizes the elements to be replaced separately for an accelerated color change.
  • Fig. 1 shows a plate cylinder 1, on which an equally large inking roller 2 is set with a resilient ink-accepting surface.
  • the inking roller 2 is in contact with an anilox roller 3, which has a hard surface provided with small cups.
  • the plate cylinder 1, the inking roller 2 and the anilox roller 3 are mounted between side walls 11 of the printing press.
  • the anilox roller 3 interacts with a chamber doctor blade 4, which has a working doctor blade 5.
  • the doctor blade 4 is firmly placed on an ink pan 6.
  • a pump 7 is arranged, which conveys the ink from the ink tank 6 through a line 8 to the doctor blade 4.
  • a motor 9, preferably an electric motor for driving the pump 7, is also fixedly arranged in or on the ink pan 6.
  • the chambered doctor blade 4 with the working doctor blade 5 thus forms a structural unit together with the ink tray 6, the pump 7 and the motor 9.
  • the actuating cylinder 20 is pivotally mounted by means of a holding rod 21 on a pin 22 fixedly attached to the side wall 11.
  • an extension 23 is also provided, through which an adjusting screw 24 is screwed.
  • the adjusting screw 24 limits the swivel path of the actuating lever 18 in the direction of arrow a and thus the pitch of the working doctor blade 5 against the anilox roller 3.
  • the adjusting arrangement shown in FIG. 2 is expediently again provided in the same way on the opposite side wall.
  • only one structural unit extending over the entire length of the anilox roller 3 or, as in the exemplary embodiment, a plurality of structural units arranged side by side can be provided.
  • a structural unit which comprises a chambered doctor blade 30, an ink tray 31, a pump 32 and a motor 33.
  • a fixed support 34 is provided here, which is on the two side walls of the printing press, not shown is attached.
  • An actuating shaft 35 is rotatably mounted on the carrier 34 and carries two actuating arms 36, 37 on each side of the ink tank 31.
  • the actuating arms 36, 37 cooperate with a pin 38, which are each attached to an outside of the ink pan 31.
  • the chamber doctor 30 is set against a screen roller 39 by means of the actuating arm 36 via the pin 38 in the direction of arrow b.
  • the assembly units 30 to 33 are turned off by the anilox roller 39 against the direction of arrow b via the actuating arms 37 and the pins 38, so that the assembly is removed from the machine and a new assembly is used can. It is also possible to dispense with the actuating arms 37.
  • a structural unit which comprises a chambered doctor blade 40, an ink tray 41 and a pump 42.
  • a motor 43 is provided to drive the pump and is attached to a side wall 44 of the printing press.
  • the motor 43 drives a shaft 45, on which a bevel gear 46 is placed for each pump 42 to be driven.
  • the bevel gear 46 is in engagement with a bevel gear 47 which is firmly placed on an output shaft 48.
  • One half of a releasable coupling 49 sits on the output shaft 48, the other half of which is fastened on a pump shaft 50.
  • a bushing 51 is fastened, on which an end flange 52 of a carrier 53 is rotatably mounted.
  • the carrier 53 serves to hold the structural unit consisting of the doctor blade 40, ink pan 41 and pump 42.
  • the structural unit 40 to 42 can in turn be placed on an anilox roller 54 with the working doctor blade 56 or can be removed from it.
  • a locking lever 55 which can be designed in the same way as in the first exemplary embodiment, is used to fix the structural unit 40 to 42 on the carrier 53.
  • the pivoting of the carrier 53 around the bushings 51 can, as in the first exemplary embodiment, take place by means of an actuating cylinder.
  • the carrier 53 To remove the structural unit 40 to 42 from the carrier 53, the latter is pivoted a short distance counterclockwise and then the locking lever 55 is moved into the unlocked position.
  • the assembly 40, 42 can now be pulled off the carrier 53 in the direction of the arrow c.
  • the two halves of the coupling 49 come out of engagement.
  • a new unit can be attached to the carrier 53.
  • the structural unit additionally includes an actuating element 70 which is attached firmly to the doctor blade 61 or the ink tray 62.
  • the actuating element 70 has a pin 71 on the output side, which engages in a sliding block 72.
  • a pin 73 is partially inserted into the sliding block 72 and passes through a longitudinal slot 74.
  • the freely protruding from the sliding block 72 end of the pin 73 passes through an elastic seal 76 and a fitting bore in a doctor blade 77.
  • the doctor blade 77 is held by means of a clamping jaw 78 on the housing 75 of the chamber doctor blade 61 so that it in or against the direction of Arrow d can be moved.
  • the doctor blade 77 of the chamber doctor blade 61 is thus not adjusted to an anilox roller 79 by moving the entire structural unit 61 to 63 but by an individual adjustment of the doctor blade 77.
  • this Adjustability of the doctor blade also to be provided in the other exemplary embodiments if a fine adjustment of the blade is additionally desired.
  • a pivotable carrier 85 which is designed and mounted in the same way as in the arrangement according to FIGS. 4 and 5, is provided.
  • a unit can be placed on the carrier 85, which comprises an ink pan 86, a pump 87, a chamber doctor blade 88 with a working doctor blade 89 and an anilox roller 90.
  • the anilox roller 90 is rotatably mounted about an axis 91.
  • the axis 91 is inserted at both ends in a fork-shaped holder 92. In order to prevent rotation of the axis, it is provided with a flat 93 in the area of the holder 92.
  • the structural unit can additionally comprise an actuating element 94 which corresponds to the actuating element 70 according to FIG. 7 and by means of which the working doctor blade 89 can be placed individually on the anilox roller 90.
  • a drive shaft 96 which drives an output shaft 99 via two cone carriers 97, 98.
  • One half of a coupling 100 sits on the output shaft, the other half of which is fastened on a pump shaft 101.
  • a locking lever 102 in turn serves to fix the assembly 86, 87, 88, 90.
  • the anilox roller 90 By pivoting the carrier 85 in the direction of the arrow e, the anilox roller 90 is placed against an inking roller 95 in this embodiment. By pivoting the carrier 85 in the opposite direction, the anilox roller 90 is lifted off the inking roller 95. In this position, the assembly 86, 87, 88, 90 can be replaced.
  • a pivotable carrier 110 is provided, which is designed in the same way as the carrier 12 according to FIGS. 1 and 2 and can also be pivoted in the same way.
  • a paint tray 111 can be placed on the carrier 110.
  • a dipping roller 112 is arranged in the ink tank 111 and partially dips into the ink.
  • the dipping roller 112 interacts with an anilox roller 113.
  • the anilox roller 113 is rotatably mounted about an axis 114.
  • the axis 114 is held non-rotatably in a fork-shaped holder 115.
  • the holder 115 is firmly connected to the ink pan 111.
  • a clamping bracket 116 for a doctor blade knife 117 is also attached to the ink pan 111.
  • the anilox roller 113 interacts with an applicator roller 118 which is mounted on the side walls of the printing press, not shown.
  • the dipping roller 112 can be set in rotation by friction from the application roller 118 via the anilox roller 113.
  • a central drive according to FIGS. 4 and 5 can also be provided for the plunger roller 112.
  • the ink tray 111 with the rollers 112, 113 and the doctor blade 117 form an interchangeable unit.
  • the ink pan 111 is directly associated with an anilox roller 113 adapted to the color contained in it. In the event of a color change, there is therefore no need to separately replace an anilox roller stored in the machine.
