Definitions

  • the invention relates to a device for accurate sheet transfer between the printing units of a multi-color printing machine according to the preamble of the first claim.
  • the object of the invention is to develop catch forks for a two-stage axial alignment of gripper carriages.
  • the advantage of the invention is, in particular, that the gripper car can be axially pre-aligned by the same catch fork and then axially, tangentially and radially aligned.
  • the gripper car can be axially pre-aligned by the same catch fork and then axially, tangentially and radially aligned.
  • the axial pre-alignment due to the calmed enema that takes place in two stages, i.e. The axial pre-alignment, the desired play-free guidance over a longer period of time and deviations of the gripper carriage from its target position are gently eliminated.
  • Fig. 1 the machine overview is shown in which the sheet transport system is used between the printing units I and II.
  • the gripper carriages 3 are guided on rails 12 and are driven by endless chains 4.
  • the sheet is transported after printing in the printing unit I from the take-up drum 5 to the feed drum 6 in the printing unit II.
  • the catch fork 11 is rigidly connected to the feed drum 6 and rotates with it. It grasps the gripper carriage 3 on its cam roller 10 and presses it outward, so that the rollers 9 of the gripper carriage 3 are pressed against the running rail 12 without play.
  • the side stand of the printing press is identified by 13.
  • Fig. 3 the connection between the chain 4 and the gripper carriage 3 is shown.
  • the drive roller 8 on the chain 4 engages in the backdrop 7 of the gripper carriage 3 like a sliding block.
  • the catch fork 11 For an axial alignment of the gripper carriage 3 in two stages, the catch fork 11 according to FIG. 4 has a first flank 16 slightly below the dimension a of a second flank 15.
  • the undersize of the flank 16 is a - 0.05 mm for a pre-alignment and the flank 15 has the exact dimension a for a suitable sheet transfer.
  • An entry zone 14 is provided to absorb radial shocks.
  • Hardened guide plates 17, 18, in which the catch forks 11 are guided, are also provided in a slot of the gripper carriage 3.
  • the flanks 15, 16 of different strengths, in cooperation with the hardened guide plates 17, 18, achieve a calmed, wear-free inlet. Additional means for the axial alignment of the gripper carriage are no longer provided, as has always been necessary up to now.
