Definitions

  • the invention relates to a device for printing on and off a cylinder of a rotary printing press, the axis of the cylinder being mounted in pivotally arranged bearing lifts.
  • Such a device is known from DE 32 32 171 A1.
  • This shows a rubber cylinder of a rotary printing press, which is eccentrically adjustably mounted at the end of a bearing lever, in which working cylinders are provided on each of the side frames, each of which engages on the bearing levers in order to position the rubber cylinder.
  • the invention is therefore based on the object of providing a device for synchronizing the pivoting movement of the axis of a cylinder.
  • the advantage of the invention is in particular that a parallelism of the axis of the pivotable cylinder, for. B. a rubber or blanket cylinder (offset cylinder) in relation to the axis of an adjacent cylinder, for. B. a cylinder carrying the print image (plate cylinder) of a rotary printing press can be maintained within a narrow tolerance range (approx. 0.02 mm).
  • a narrow tolerance range approximately 0.02 mm.
  • axle guides according to the invention as crank drives is structurally simple and therefore inexpensive to manufacture.
  • an additional adjusting movement of the axis of the cylinder to be adjusted can be recorded by means of the crank mechanism, which is caused by an eccentric bushing, which causes the rubber cylinder to move away from the plate cylinder.
  • crank mechanism The arrangement of the joint elements (crank, handlebar) of the crank mechanism at an angle ⁇ of approximately 90 ° to one another minimizes the forces occurring in the joint elements, as a result of which they can be dimensioned small.
  • a working cylinder for positioning it is provided on both sides of the side frames for each bearing lever.
  • the synchronizing device according to the invention also makes it possible to provide only one working cylinder arranged on any side.
  • a printing unit 1 of a rotary printing press has, inter alia, a plate cylinder 2, a rubber cylinder 3 interacting with it and a printing cylinder 4.
  • the plate cylinder 2 and the printing cylinder 4 are rotatably mounted in side frames 5, 6 of the rotary printing press.
  • the rubber cylinder 3 is rotatably mounted on an axis 7, which in turn is rotatably mounted in two bearing levers 9, 11 each arranged outside the side frames 5, 6 and pivotable about the axis 8 of the plate cylinder 3. With this arrangement, the blanket cylinder 3 remains engaged with the plate cylinder 2 during the printing on / off.
  • the axis 7 is supported in the bearing levers 9, 11 by means of an adjustable eccentric bushing 12; 13.
  • the rubber cylinder 3 can also be switched off from the plate cylinder 2 in a printing stop by the printing cylinder 4.
  • working cylinders 14, 16 are provided, which are pivotably mounted on the bearing levers 9, 11 and each engage with one end of their piston rod 17, 18 on a toggle lever joints 22, 23 consisting of two levers 19, 21. These are each articulated with the first lever 19 on the bearing lever 9; 11 and articulated with the second lever 21 on the eccentric bushing 12; 13.
  • the ends 24, 26 of the rubber cylinder 3 protrude without contact on both sides through the side frames 5, 6 and through the eccentric bushes 12, 13 and each carries a crank 27, 28 in a rotationally fixed manner.
  • the crank 27; 28 is pivotally connected to a link 29; 31 which is rotatably mounted on a bolt 32; 33 fixed to the frame.
  • An angle ⁇ between crank 27; 28 and handlebar 29; 31 is z. B. about 90 °.
  • the eccentric bushes 12, 13 can be used to shut off the rubber cylinder 3 from the plate cylinder 2 by retracting the piston rods 17, 18 of the working cylinders 14, 16 and deflecting the toggle joints 22, 23.
