Definitions

  • the invention relates to a suspension for a device for changing printing plates according to the preamble of claim 1.
  • a device for changing printing plates in the form of a magazine is known that on the delivery side of the printing unit is vertically displaceable via a straight guide attached to a side frame part.
  • this magazine can be moved from a basic position to a service position above it.
  • the straight guide on the side frames of the printing unit only have a length which corresponds to the dimensions of the magazine, the underside of the magazine still covers parts of the inking unit and, in particular, the ink fountain when pushed up. This is considered to be disadvantageous.
  • the object of the present invention is therefore to expand a suspension according to the preamble of claim 1 in such a way that there is optimal accessibility to the upper parts of the inking unit.
  • the straight guide for the printing plate change telescopic, so that this completely releases the printing and inking unit in the raised position. It can even be provided that the telescopic linear guides are designed in such a way that the printing plate changer can be moved beyond the printing unit.
  • Fig. 2 shows a printing unit 1 of a sheet-fed offset printing machine with a printing plate changer 2 arranged on the delivery side.
  • a new printing plate to be fed to the plate cylinder can be set, and it can also be provided that a printing plate conveyed from the plate cylinder is conveyed into the printing plate changer and there to Removal is provided.
  • the printing plate changer 2 is attached to the printing unit 1 in a vertically displaceable manner. As shown in FIG. 1, the printing plate changer 2 can be moved from the basic position (FIG. 2) to a service position (FIG. 1) via a telescopic guide 3 attached to a side frame wall of the printing unit 1.
  • the telescopic guide 3 according to the invention consists of three rails 4, 5, 6, one rail 4 each being arranged on the cantilever side of the frame wall 7 (FIG. 3) of the printing unit 1.
  • an inner rail 5 is mounted so as to be movable with respect to the rail 4 fixed to the frame via rolling elements 8.
  • a rail 6 which is fixedly arranged on the outer regions of the pressure plate changer 2 is movably mounted relative to the inner rail 5.
  • the printing plate changer 2 If the printing plate changer 2 is now shifted from the basic position into the extended position, the two rails 5 - one rail 5 on each side of the printing plate changer 2 - partially move out of the rail 4 in their length.
  • the rails 6 attached to the pressure plate changer 2 are also moved relative to the rails 5, so that the rails 5 are only partially immersed in the rails 6 in their length. The result of this is that the printing plate changer 2 can be moved into a position above the printing unit 1, so that access to an ink fountain (not shown) or other elements arranged in the upper region of the printing unit 1 is ensured.
  • Fig. 3 shows the telescopic guide 3, consisting of the rails 4, 5, 6 and the rolling elements 8 arranged in between again in detail.
  • the rails 4, 5, 6 consist of profiled material and are shaped in cross section according to the shape of the rolling elements 8.
  • the outer rail 4 is on holder the frame wall 7 arranged.
  • the rails 4, 5, 6 on the opposite frame wall 7, not shown, or at the other end of the pressure plate changer 2, are mirror images of the manner shown in FIG. 3.
  • Fig. 4 shows a preferably used drive for the pressure plate changer 2, wherein a traction mechanism in the form of a cable is provided here.
  • ropes 10 are looped over a system of loose rollers 9, which are fixed on the pressure plate changer 2.
  • a pneumatic cylinder 11 which is arranged on the inside, i.e. the side of the printing plate changer facing the printing unit cylinders, a pull is exerted on the cables 10, so that the large travel of the printing plate changer 2 is made possible with a relatively small stroke of the piston rod of the pneumatic cylinder 11 .
  • the loose rollers 9 thus result in a translation of the stroke. 4 shows the printing plate changer 2 in its basic position corresponding to FIG. 2.
