Definitions

  • the invention relates to a device for changing printing plates according to the preamble of claim 1.
  • an insertion bar for feeding printing plates which consists of an insertion rail which is mounted on the plate cylinder and can be removed with respect to the latter.
  • the plate cylinder is moved into a predetermined position and the insertion rail is placed against it.
  • the front edge of a pressure plate to be fed now slides on the insertion surface of this insertion rail pointing towards the plate cylinder into the open detection area of a clamping rail assigned to the start of printing.
  • This insertion rail has a stop at each of its two ends, by means of which it is supported on the bearer rings of the plate cylinder.
  • a pressure roller mounted on and off the plate cylinder and a folding bar is known.
  • the pressure plate is pulled around the outer circumference of the plate cylinder by means of the pressure roller, the latter rotating forwards.
  • the folding bar is set up, whereby the bending of the printing plate takes place by a bend at the printing end.
  • This fold bar has no adjustable stops, so that the thickness of the fold impressed on the pressure plate, that is to say the bending, cannot be changed.
  • the folding bar is supported directly on the front clamping rail or on the contour of the printing end of the plate cylinder, so that the required geometric conditions for feeding a new printing plate or for inserting the printing end of the printing plate into the tensioning rail by means of a corresponding design with one another to define interacting components and therefore not to be changed.
  • the object of the present invention is therefore to extend a device according to the preamble of claim 1 such that the usability of a device serving to change printing plates can be expanded.
  • FIG. 5 shows a plate cylinder 1 with an axially parallel pit 3 mounted therein.
  • the plate cylinder 1 On the two end faces of the plate cylinder 1, the latter has a bearer ring 2. These bearer rings 2 interact with corresponding rings of a blanket cylinder, not shown, in a known manner.
  • a clamping or clamping rail 4, 5 assigned to the start of printing is arranged in the pit 3 of the plate cylinder 1.
  • the tensioning or clamping rail 4, 5 the fastening and then tensioning of the printing start or the printing end of a printing plate, not shown in FIG. 5, takes place.
  • FIG. 6 shows a plate cylinder 1 with a pressure plate 9 located thereon.
  • a folding bar 7 runs parallel to the axis of the plate cylinder and is supported on the ends extending beyond the format limits of the plate cylinder by an adjusting device (not shown) with respect to the plate cylinder 1 .
  • This switch-on and switch-off device can consist, for example, of a bearing lever attached to the frame wall of the printing unit, each of which is connected to one end of the folding bar 7.
  • the stops 10, 11 are screws which are rotated through corresponding threaded bores in the folding bar 7 and the stop 10, which is used for support on the surface of the plate cylinder 1, continues protrudes in the direction of the plate cylinder 1 as the stop 11, which serves to support the folding bar 7 on the bearer ring 2.
  • FIGS. 3 and 4 show the position of the folding bar 7 with the insertion rail 8 attached to it according to FIGS. 1 and 2.
  • FIG. 3 for folding and inserting a pressure plate 9 into the clamping rail 4 assigned to the printing end 9, an axially parallel and the pulling-up of the plate is shown serving pressure roller 6 placed on the plate cylinder.
  • the folding bar 7, which is pivotably mounted with respect to the pressure roller 6, is placed against the plate cylinder by means of further adjusting means (not shown) (e.g. pneumatic cylinders).
  • the insertion rail 8 which is attached to the folding bar 7 and which is used to feed a new printing plate.
  • FIG. 4 shows the position of the folding bar 7 together with the insertion rail 8 for feeding a new pressure plate 9 into the open clamping area of a clamping rail 5 assigned to the start of printing.
  • the plate cylinder 1 can now be seen moved into such a position so that the stop protruding further in the direction of the plate cylinder 1 10 is supported on the circumference of the plate cylinder 1 and thus the clamping bar 7 along with the folding bar 8 assumes a position with respect to the plate cylinder 1, so that the front edge of the pressure plate 9 on the side of the insertion rail 8 facing the plate cylinder 1 slides into the clamping area of the clamping rail 5 can. Since the protruding stop 10 rests on the outer circumference of the plate cylinder 1, the stop 11 does not come into contact with the surface of the bearer ring 2. The situation according to FIG. 4 is shown again in another view in FIG. 2.
  • the stops 10 and 11 are screws which are rotated through corresponding threaded holes in the folding bar 7. This makes it possible to set the folding bar 7 in connection with the insertion rail 8 attached to it in a precisely defined manner, that is to say to create optimum conditions for feeding a new printing plate into the clamping rail 5 of the plate cylinder 1 at the start of printing. There are also optimal conditions at the printing end of the plate cylinder. In order to achieve damage-free protection of the stops 10 and 11 on the plate cylinder 1 or the bearer ring 2, provision can further be made to match the material of the stops 10, 11 designed as screws with that of the plate cylinder 1 accordingly.
  • the two further stops 10, each lying next to the bearer rings 2 are assigned support surfaces. These support surfaces can in particular be attached to the end faces of the bearer rings 2 and prevent the stops 10 from being supported on the surface of the plate cylinder 1.
