Definitions

  • the invention relates to a device for feeding printing plates onto the plate cylinder of printing presses, the plate cylinder being arranged axially to the plate cylinder Has plate cylinder channel in which a tensioning rail for receiving the front edge of the Pressure plate is arranged.
  • a device is known through which the printing plates in the open detection area of a clamping rail of a plate cylinder assigned to the start of printing can be introduced. In doing so, it is moved to those moved to a certain angular position Plate cylinder in such a way on an insertion rail extending over the format width the outer circumference of the plate cylinder in the area of the start of printing that the front edge the pressure plate directly into the via the insertion surface formed by the insertion rail Detection area of the pressure start clamping rail can be introduced.
  • the outer circumference the plate cylinder thus forms a funnel-shaped area for the with the insertion rail Printing plate leading edge.
  • the object of the invention is to develop a device by which the Pressure plate from an exact pre-positioning in the open mouth of the pressure plate clamping rail can be introduced.
  • the invention has the advantage that only a small amount for the exact insertion of the printing plate mechanical effort is required.
  • the way from prepositioning to the clamping point is in short, which contributes to the stability of the process.
  • the device for feeding printing plates consists of one Plate cylinder 1 with a plate cylinder channel 3.
  • plate cylinder channel 3 there are one Front clamping rail 31 for grasping the front edge of a pressure plate 22 and a rear one Clamping rail 32 arranged for grasping the rear edge of a pressure plate 22.
  • the structure the front tensioning rail 31 and the rear tensioning rail 32 are generally known and will be on not explained in more detail here.
  • a lay-in shaft 4 which is rotatable about its axis is arranged parallel to the plate cylinder channel. This extends over the entire format width and has a segment cutout 41 Mistake.
  • the segment cutout 41 serves to receive the front edge of the new printing plate 22 and is provided with pre-fitting pins 42.
  • the exemplary embodiment is described using an insertion shaft 4. But it is also possible to use another rod-shaped element and on this a suitable receptacle to be arranged for the front edge of the new pressure plate 22.
  • the plate cylinder 1 is also assigned a storage roller 6, which is the guide or the storage the used printing plate.
  • a guide plate 71 is assigned, which with a guide plate 81 the discharge shaft 7 for used printing plates.
  • the feed shaft 8 for new printing plates 22 is through the Guide plates 81 and 82 formed.
  • the new printing plate 22 is fed through the feed shaft 8 introduced and stored in the segment cutout 41 on the pre-fit pins 42.
  • the new pressure plate 22 is clamped on its rear edge.
  • the new pressure plate 22 can be pressed lightly against the pre-fitting pins 42 so that they fit in this position is under tension.
  • Another variant of the invention is the new one Pressure plate 22 is not under tension, but is due to its weight on the pre-fit pins 42 on.
  • the rear clamping rail 32 is now opened.
  • the drives Plate cylinder 1 in a position in which the protruding from the rear clamping rail 32
  • the trailing edge of the used pressure plate 21 comes to rest on the storage roller 6.
  • the front tensioning rail 31 is opened.
  • the insertion shaft is rotated in the direction of the arrow until approximately the position shown in FIG. 2 is reached.
  • the new pressure plate 22 jumps out of the segment cutout due to the pretension 41 and slides into the open front tensioning rail 31. If there is no pretension, due to its weight, the new pressure plate 22 slips into the front tensioning rail 31.
  • the new printing plate 22 is then placed on the plate cylinder 1 in the known manner reared.
