Definitions

  • the invention relates to a device for feeding a printing plate to the plate cylinder of a printing press according to the preamble of claim 1.
  • so-called semi-automatic printing plate changers represent where the clamping and tensioning by remote controllable Positioning device takes place, the removal of an old, used Printing plate and feeding a new printing plate from or to However, plate cylinder is done by an operator.
  • a such device is for example from the DE 4 214 049 C2 is known, in which a vertically in front of printing unit cylinders slidably and at the same time pivoted Protection holding devices for the new pressure plate to be fed has, the holding devices on the one hand rotatable stored role at the bottom of the protection as well as one or there are several suction cups in the upper area of the protection.
  • the plate is manually in the appropriate clamping device of the plate cylinder inserted and then clamped. By The printing plate is then opened by rotating the plate cylinder forward raised this.
  • This known, partially automated printing plate feeder but provides that the printing plates to be used are folded at the end. So that the suction cup or cups when pulling up the pressure plate just before reaching the bend Release the pressure plate is provided, ventilation holes in the pressure plate to provide. After releasing the end of the pressure plate through the suction cup or cups, the pressure plate is now only guided through the roll so that its end sags and possibly due to this movement on the printing side Experiences damage. Moreover, the openings to be provided the printing plate at the end of its printing to be regarded as disadvantageous. By Contamination of the suction cups is also crucial to their holding power decreased.
  • the object of the present invention is therefore a device to develop further in accordance with the preamble such that the Feeding a new printing plate with reduced handling effort take place at the same time with little construction effort can.
  • Figures 1 to 3 show the delivery side of a printing unit plate cylinder arranged therein 1.
  • the delivery side of the printing unit is secured by a vertically movable protection 2.
  • protection 2 is included a straight guide on the side frame walls of the printing unit articulated.
  • Figure 1 shows the operating position of the protection 2, in which one is in the lowest position and thus flat the danger point of the plate cylinder 1 and the one below it covers located blanket cylinder. Above the end of protection 2, further types of contamination, not shown, are arranged. These cover the delivery side of the inking unit.
  • FIG. 2 shows the protection with the pressure plate 4 located thereon in the raised position, in which the plate cylinder 1 and the blanket cylinder underneath are accessible.
  • the stops 3 To the new pressure plate 4 to be fed, which with its front edge the stops 3 is turned off, in an approximately vertical
  • To keep orientation is the support device according to the invention 6, each with a joint 9 with protection 2 in the lower Area connected, pivoted into a vertical position.
  • the support device 6 according to the invention as an im essentially U-shaped bracket made of round material and over two joints 9 in the lower area of the protection 2 with this connected.
  • the pivotable articulation of the support device 6 opposite the protection 2 allows the pressure plate 4 to be fed with protection 2 pushed up in an oblique direction of extension of protection 2 level of the clamping rail 7 of Plate cylinder 1 is supplied.
  • the support device 6 from the basic vertical position into the position shown in FIG. 3 Positioned and then the of the stops 3 pressure plate 4 taken into the clamping gap of the clamping rail 7 introduced. Then it is done either manually or on Remote control clamping the pressure plate front edge.
  • At least one of the side stops 10 to adapt to different plate formats in Axial direction of the plate cylinder 1 movably attached to the protection 2 is.
  • FIGS. 5 and 6 show a joint 9 and that of joint 9 assigned means for limiting the pivoting movement of the invention Support device 6.
  • end the horizontally angled legs of the essentially U-shaped bracket each on a block attached to the protection 2 11.
  • the two ends of the tube of the support device 6 have each have a plate 12, in the center of the axis of the tube the support device 6 has a hole machined into it pin 13 inserted in block 11 is immersed. Pin 13 thus forms in connection with the bore in the plate 12, the joint 9 of the Support device 6.
  • Figure 5 represents one shown from above View of the joint 9 on the left in FIG. 4.
  • A-A is a view shown in Figure 6 characterized which the hinge 9 with the lower part of the Protection 2 reproduces.
  • the one pointing to protection 2 and firmly attached to the Support device 6 attached part of the plate 12 is there with an arcuate slot 14 through which the shaft a screw 15 screwed into the block 11 passes through.
  • Shank of the screw 15 thus defines in connection with the Dimensions of the slot 14 between the possible pivot path Basic and working position of the support device according to the invention 6.
  • Figure 6 gives the position of the plate 12 and thus the support device 6 according to Figures 1 and 2, that is, the basic position the support device 6 again.
  • the joint 9 described above with reference to FIGS. 5 and 6 is outside the format limits of a largest to be processed Pressure plate 4 mirror image of each other in the lower area the protection 2 attached (Fig. 4).
