Definitions

  • the invention relates to a device for parallel clamping of printing plates on a plate cylinder according to the preamble of the first claim.
  • the rear tensioning rail can only be tensioned with an increased tensioning path from a relaxed position advanced against its channel wall with a quick-action clamping mechanism with lever transmission in the cylinder circumferential direction. If the clamping screws in the rear clamping rail are not loosened exactly the same distance during the preparatory work for clamping a new pressure plate, then the rear clamping rail, which is not precisely guided on the side, is tilted during quick clamping and the rear pressure plate end is pulled obliquely, which means that the pressure plate is sensitive on one side is stretched and warps. It is then no longer possible to clamp the plate precisely, since the plastic deformation can no longer be undone by subsequent correction using the clamping screws.
  • the quick release mechanism known from DE-PS 2 754 080 does not have a series connection of a quick release device for pre-tensioning and tensioning device for the final tensioning. In this way, tilting of the rear tensioning rail can be avoided, because the rapid mounting of the pressure plate with a precisely defined tension takes place with a single adjustment process by parallel guidance of the rear tensioning rail in the cylinder channel by means of a symmetrical scissor arm linkage.
  • this quick release device according to FIG.
  • a quick clamping device for parallel clamping in which an angular rail for clamping printing plates of different printing lengths is arranged in several fixed positions in parallel to the end of the print adjustable and lockable, but only a limited clamping force by one on the Angled rail acting leaf spring can be generated during quick clamping.
  • the device can be equipped with a split tensioning rail, but a section-wise correction of the printed image is not useful because a split rear tensioning rail is coupled again via the quick-action clamping device arranged symmetrically in the cylinder center plane. This means that the functions of quick clamping and final clamping are inseparable, which means that undesired feedback on the clamping force is unavoidable.
  • the invention is therefore based on the object of providing a device which makes it possible, with defined clamping forces, to move a rear continuous or divided clamping rail parallel to its channel wall during quick clamping in the clamping direction, without impairing the final clamping via the quick clamping mechanism and thereby arrange the quick release mechanism in the plate cylinder to save as much space as possible.
  • the advantage of the device is that printing plates can be clamped in parallel with a defined clamping force in order to achieve register accuracy, but at the same time the known correction options for the printed image during final clamping with a split clamping rail and the associated clamping screws are retained.
  • the plate cylinder 1 of a printing press has means for fastening and tensioning printing plates in a cylinder channel 2.
  • these fastening means are designed as a front tensioning rail 3 divided over the length of the plate cylinder 1 and a correspondingly divided rear tensioning rail 4, and are each arranged at the print start 5 and print end 6 of the cylinder channel 2.
  • the divided clamping rails 3, 4 are arranged in a known manner in the cylinder channel 2 and are actuated by means of clamping screws 10, 11.
  • the pressure plate front edge and the pressure plate rear edge are also clamped in a known manner by clamping devices 21, 22 (FIG. 2).
  • the quick release device consists of a pressure bar 9 for the tensioning screws 11 arranged along the cylinder channel 2 in a recess 7 of the plate cylinder 1 running parallel to the channel wall 8.
  • the pressure bar 9 is divided in the rear by an outside of the cylinder center plane parallel to the tensioning screws 11 Clamping rail 4 arranged eccentric 12 along the cylinder channel 2 slidably.
  • a parallel movement in the tensioning direction can be carried out from the pressure bar 9 via specially designed recesses 13 and corresponding elevations, which are designed as pressure rollers 14 on counterparts 15, which lie opposite the tensioning screws 11 supported under the action of a compression spring 16.
  • the depressions 13 in the pressure bar 9 are formed with a slope according to FIG. 3 which is larger and then smaller at the beginning of the tensioning path and runs into a radius R.
  • the divided clamping rails 3, 4 are guided axially displaceably in the cylinder channel 2.
  • the setting angle ⁇ of the eccentric bolt 12 is shown in three positions in FIG. 4.
  • the eccentric bolt 12 carries out a compensating movement by the angle ⁇ with the axial adjustment, while the pressure bar 9 remains in its position or, with a corresponding design, the pressure bar 9 can also carry out the compensating movement.
  • the divided clamping rails 3, 4 are slidably guided in sections in the circumferential direction and parallel or obliquely to the cylinder axis, also overall, in a known manner.
  • a parallel movement in the clamping direction during quick clamping is possible without the known correction possibilities in the circumferential direction and / or in the axial direction being restricted by the quick clamping mechanism.
