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 is known, which from a mounted on the plate cylinder and stored with respect to this Insertion rail exists.
  • the plate cylinder is used to feed a new printing plate move to a specified position and the insertion rail is placed against it.
  • the front edge of a pressure plate to be fed now slides on to the plate cylinder indicative insertion surface of this insertion rail in the open detection area of a the clamping rail assigned to the start of printing.
  • This insertion rail points to both of them End each one stop, by means of a support on the bearer rings of the Plate cylinder is done.
  • the pressure roller is used to pull the Pressure plate around the outer periphery of the plate cylinder, which rotates forward.
  • the tensioning rail is used to set the folding bar, thereby bending the Pressure plate around a fold at the end of the print.
  • This fold bar has none adjustable stops so that the thickness of the bend impressed on the pressure plate, so the angle 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 clamping rail by means of a corresponding one To define the design of the interacting components and therefore not to are changing.
  • the object of the present invention is therefore a device according to the preamble of Claim 1 to expand in such a way that the usability is a change of Printing plate serving facility can be expanded.
  • FIG. 5 shows a plate cylinder 1 with an axially parallel pit 3 attached to it
  • the two end faces of the plate cylinder 1 each have a bearer ring 2.
  • These bearer rings 2 act with corresponding rings of a not shown Blanket cylinder together in a known manner.
  • In the pit 3 of the plate cylinder 1 are one clamping or clamping rail 4, 5 assigned to the beginning of the printing (or printing end).
  • In the tensioning or clamping rail 4, 5 is attached and then tensioned Beginning of printing or end of printing of a printing plate not shown in FIG. 5.
  • Fig. 6 shows a plate cylinder 1 with a printing plate 9 thereon.
  • Parallel to An axis of the plate cylinder runs a folding bar 7, which in each case on the Format limits of the plate cylinder extending ends over a not shown Adjusting device with respect to the plate cylinder 1 is carried on and off.
  • This arrival and Parking device can for example consist of one on the frame wall of the Printing unit attached bearing levers, each with one end of the Folding bar 7 are connected.
  • FIGS. 1 and 2 show the position of the folding bar 7 with the attached Insertion rail 8 according to FIGS. 1 and 2.
  • FIG. 3 there is a for folding and insertion Pressure plate 9 in the clamping rail 4 assigned to the printing end an axially parallel and the pressure roller 6 serving to pull the plate up against the plate cylinder.
  • actuating means not shown (e.g. pneumatic cylinder) is pivotable with respect to the pressure roller 6 mounted folding bar 7 placed on the plate cylinder.
  • the insertion rail 8 which is attached to the folding bar 7 and which the Feeding a new printing plate is used.
  • FIG. 4 the position of the folding bar 7 along with the insertion rail 8 for feeding one new printing plate 9 in the open clamping area of one assigned to the start of printing Clamping rail 5 shown.
  • the plate cylinder 1 can now be seen in one of these Move the 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 folding bar 7 along with Insertion rail 8 assumes a position with respect to the plate cylinder 1, so that the Front edge of the printing plate 9 on the side facing the plate cylinder 1 Guide rail 8 can slide into the clamping area of the clamping rail 5. Since the further 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 The situation according to FIG. 4 is shown again in another view in FIG. 2.
  • the stops 10 and 11 are concerned around screws which are rotated through corresponding threaded holes in the folding bar 7 are. This makes it possible to connect the folding bar 7 in connection with the attached Adjust the insertion rail 8 in a precisely defined manner, that is to say optimal conditions for feeding a new pressure plate in the clamping rail 5 of the plate cylinder 1 at the start of printing create. There are also optimal conditions at the printing end of the plate cylinder.
  • the material can also be provided as screws trained stops 10, 11 to match that of the plate cylinder 1 accordingly.
