Definitions

  • the invention relates to a device for adjusting the pressure of a pressure cylinder equipped with a push-on sleeve.
  • a device is known (DE-OS 37 02 889), in which for a sleeve change of the printing cylinder, the frame walls are equipped with laterally movable jaws, which serve to support the printing cylinder, each of which has a toothed electric motor as an eccentric adjustment, which engages in an eccentric bushing equipped with teeth and used to adjust the pressure cylinder during operation.
  • the jaws which can be moved apart require a relatively large amount, particularly in the case of a multi-cylinder arrangement, which is difficult to realize.
  • the guides for the jaws are difficult to manufacture in terms of the accuracy requirements to be placed on them.
  • the invention has for its object to provide a device for adjusting the pressure of a printing cylinder equipped with a push-on sleeve according to the preamble of claim 1, which enables simple, space-saving means of changing the sleeve in the rotary printing press and a functionally reliable adjustment of the printing cylinder in the operating state.
  • the device which consists of simple components, can be arranged in any freely available place in the area of the pressure cylinder bearing and requires little space for its adjustment from the operating position to the position for changing the sleeve. With regard to the robustness and simplicity of the means used, it guarantees a functionally reliable adjustment of the printing cylinder even after a long period between adjustments.
  • the stop according to claim 2 and in its specific embodiment according to claim 3 enables an adjustment of the tooth segment with respect to the toothing of the eccentric bushing in Operating case.
  • the arrangement of the working cylinder according to claim 4 ensures that it is free from a restoring moment on the pivot lever.
  • Claim 5 calls an inexpensive drive variant for the toggle lever, the point of application of the working cylinder being variable with regard to the design of the device and the space available.
  • Claim 6 calls a simple implementation option for the toothing of the eccentric bushing.
  • Claim 7 and its specific configurations according to claims 8 and 9 ensure in a simple manner on the one hand the fixing of the bearing bush supporting the journal of the pressure cylinder against rotation of the eccentric bushing causing the pressure setting of the printing cylinder and on the other hand clearing the opening in the frame wall from the locking body for the sleeve change.
  • pivot lever 7 On the pivot lever 7 is one of two links 11; 12 existing, the pivoting of the toothed segment 8 from its operating position into an opening in the frame wall 6 in the form of a wall bore 13 to clear the position causing the sleeve, articulated at its other end in the frame wall 6 mounted toggle lever 14.
  • a pressure medium-operated working cylinder 15 which is pivotally mounted in the frame wall 6 and is only partially shown in FIG Operating state adjusting, the pivot lever 7 serving as a system, consisting of a frame-fixed, 17 through a set screw 16 in a threaded hole existing stop 18 is limited.
  • the bearing bushing 20 which is supported by three support bodies 19 which can be adjusted from the region of the wall bore 13 and which can be changed from the area of the wall bore 13, is fixed against rotation by the eccentric bushing 4 when the pressure cylinder is set, the latter also has a toothed segment 21 in front which engages in the operating state an adjustable on the pivot lever 7, with the latter pivotable for changing the sleeve from the region of the wall bore 13 further tooth segment 22 (Fig. 2).
  • the latter is also conveniently mounted on the bearing pin 23 for the adjustment of the eccentric bushing 4, which is omitted in FIG. 2, and is equipped with a clamping screw 25 which extends through a slot 24 extending in the pivoting direction and is guided in a threaded bore of the pivoting lever 7 .
