Definitions

  • the invention relates to a device for fastening flexible printing plates on a plate cylinder of rotary printing machines.
  • a known embodiment of this type (DE 37 31 039 A1) discloses a clamping device for flexible pressure plates, in which lever elements clamp and tension the pressure plate via pneumatic or hydraulic elements.
  • the object of the present invention is to simplify the clamping and tensioning of the pressure plate and to provide a device which ensures that the pressure plate is clamped and tensioned during operation of the machine without the supply of energy.
  • the object is achieved by a device with the following solution features.
  • the spring elements are arranged between the tensioning rail and camshaft and the spring-lever units are arranged between bearing arms on the tensioning rail and levers on the clamping rail.
  • a clamping device 3 for the leading plate end and a device 4 for attaching a flexible pressure plate 5 to the plate cylinder 2 are provided.
  • the device 4 consists, inter alia, of an axially parallel clamping rail 6 arranged in the pit 1 and a clamping rail 7 fastened to the clamping rail 6.
  • the clamping rail 6 is slidably mounted in the pit 1 of the plate cylinder 2 and carries bolts 8 at both ends which the clamping rail 7 is pivotally mounted.
  • a camshaft 9 is provided, which is rotatably mounted in the end faces of the plate cylinder 2.
  • the camshaft 9 carries two pairs of cams 10, 11, the pair of cams 10 displacing the tensioning rail 6 against the force of spring elements 12 via cam rollers 13.
  • the spring elements 12 are provided on bolts 14, which are mounted in a longitudinally displaceable manner in the tensioning rail 6 and are supported with their opposite head 15 on the camshaft 9.
  • the cam rollers 13 are attached to lever arms 16, which are also connected to the tensioning rail.
  • the second pair of cams 11 presses when the camshaft is rotated counterclockwise, pins 17 which are fastened to the clamping rail 7, so that the clamping rail 7 opens and assumes the position shown in FIG. 2.
  • the opening of the clamping rail 7 also takes place against the force of springs 18, which are actuated by levers 19, which in turn are attached to the clamping rail 7.
  • the springs 18 can be actuated via plungers 20, which are fastened on one side via pins 21 to the levers 19 and on the other side via pins 22 on the bearing arms 16.
  • Fig. 1 the pressure plate 5 is clamped between the clamping rail 6 and the clamping rail 7 and the clamping rail with the clamping rail is displaced to the right by the force of the spring elements 12, so that the pressure plate 5 is clamped on the outer surface of the plate cylinder 2.
  • the camshaft 9 is rotated clockwise in its starting position (as shown). If the camshaft 9 is now rotated counterclockwise, the tensioning rail 6 with the clamping rail 7 is first moved to the left via the cam roller 13 and the pressure plate is thus relaxed. The clamping rail 7 is then opened via the second pair of cams 11 and the pins 17, as shown in FIG. 2. Here, the tensioning rail 6 is in its left starting position.
  • a new printing plate 5 is now placed on the plate cylinder 2, it is first clamped by the clamping device 3 at its front end and pressed onto the outer surface of the plate cylinder 2 by rotating the plate cylinder 2 counterclockwise by means of rollers 23 fixedly mounted on the side frames.
  • the rollers 23 press the trailing plate end 24 into the position shown, so that the wide-opening clamping rail 7 can be closed and the plate end 24 clamped, as shown in FIG 1 is shown.
  • the pressure plate is tensioned by moving the tensioning rail 6 with the clamping rail 7 to the right.
