Definitions

  • the invention relates to a device for starting and stopping the inking rollers according to the preamble of claim 1.
  • a known embodiment of this type discloses an inking unit with three inking rollers, with a bearing on levers which are attached to the side frames.
  • the bearing levers are each assigned actuating levers that are operatively connected to one another.
  • a cam disk is provided on both sides on the bearing of the plate cylinder, on which a roller that is attached to one of the control levers rolls.
  • the inking rollers can be turned on or off by simultaneously turning the two cam disks on each side of the machine.
  • several tension springs are required which bring the control lever provided on both machine sides into contact.
  • the disadvantage of the known design is essentially to be seen in the unstable mounting of the inking roller. If they roll on the pressure plate in their adjusted position, e.g. when passing through the cylinder channel, blows occur which lead to vibrations of the rollers or the roller bearings, so that when the individual inking rollers are placed on the printing plate, the inking can be impaired. In the case of high-speed machines in particular, this can lead to roller strips which make it impossible to produce high-quality printing work.
  • the embodiment shown in the drawing relates to an offset printing unit with a plate cylinder 1 and a blanket cylinder 2 in the known embodiment.
  • four inking rollers 3, 4, 5, 6 are assigned to the plate cylinder, which are pivotably mounted about two distribution rollers 7, 8.
  • the friction rollers 7, 8 are driven by an inking mechanism drive, not shown, at machine speed.
  • the friction rollers 7, 8 supplied with a certain amount of ink by a ink metering device 10 via a plurality of inking unit rollers 9.
  • the inking rollers 3-6 are mounted in bearing levers 11-14, which are arranged pivotably about the bearings 15 of the closest distributor roller 7, 8.
  • Two bearing levers 11, 12 and 13, 14, respectively, which are provided on both machine side frames, are each connected to a control lever 20, 21 via tabs 16-19.
  • the tabs are fastened via bolts 22 to cams 23, which are each provided on the bearing levers 11-14.
  • the connection to the control levers 20, 21 also takes place via bolts 24.
  • the control levers 20, 21 themselves are fastened to the machine side frame 26 by means of stud bolts 25 (FIG. 2).
  • a compensating web 27 is provided, which is connected via stud bolts 28 to the ends opposite the bearing of the control levers on the stud bolts 25.
  • the piston rod 30 of an actuating cylinder 31 acts on this compensating web 27 via a joint body 29. This in turn is supported on the machine side frame 26 via a bearing body 32.
  • the compensating web 27 is pressed down to set the applicator rollers 3-6, so that the two control levers 20, 21 are moved like a toggle lever.
  • they press the bearing levers 11-14 downward via the bolts 24 and the tabs 16-19, so that the application rollers 3-6 come into contact with the plate cylinder 1.
  • the positioning movement is limited here by eccentric stops 33, against which the recesses 34 in the bearing levers 11-14 bear.
  • the stops 33 By turning the stops 33 via adjusting spindles, not shown, the contact force of the application rollers 3-6 on the pressure plate of the plate cylinder 1 can thus be set sensitively.
  • the inking roller 35 abutting the inking rollers 4, 5 is slidably supported by sliders 36 so that it can follow the on and off movement of the inking rollers without their own adjusting means.
  • the joint body 29 is connected to the compensating web 27 via a pin 37.
  • This figure also shows that the application rollers 3-6 are preferably interchangeably mounted via bearings 38 in the bearing levers 11 to 14.
