Definitions

  • the invention relates to a device for duplication-free pressure switching, consisting of a Impression cylinder, to which a rubber cylinder is assigned to transfer the print image, the rubber cylinder for changing the center distance to the impression cylinder in one rotatable eccentric bearing is arranged and via a gear train with the impression cylinder connected is.
  • the rubber cylinder is used to turn the plate and impression cylinders on and off stored on both sides in eccentric bushings.
  • These eccentric bushings are through a toggle mechanism pivotable that is supported on an abutment.
  • the toggle mechanism actuating means actuated by the application of pressure medium.
  • This means of control exists consisting of two parallel, double-acting working cylinders that are fixed to the frame, whose piston rods are articulated to a coupling.
  • the paddock is over one Hinge pin connected to a toggle lever gear.
  • the working cylinders are for pressure adjustment one after the other and for printing shutdown both one after the other and pressurized at the same time.
  • the hinge pin is used to change the pressure provided between the blanket and the impression cylinder - i.e. to generate the printing pressure specific to the substrate - pivotable via a spindle nut in cooperation with an adjusting spindle.
  • the adjusting spindle is actuated from the outside by a handwheel twisted. Turning the adjusting spindle causes the eccentric bushes to turn what the contact force of the rubber cylinder to the impression cylinder changed.
  • the object of the invention is to provide a device for duplication-free pressure switching develop by which the backlash is eliminated.
  • the invention has the advantage that the tooth flanks and so that an exact transmission of the grid points can be guaranteed. In order to duplication can be avoided for this reason.
  • an impression cylinder 1 is arranged on which a rubber cylinder 2 is employed. This is in contact with a plate cylinder 3.
  • the rubber cylinder 2 is mounted eccentrically. It can be seen that the rubber cylinder axis 23 is mounted eccentrically to the rubber cylinder bearing 24.
  • the eccentric 25 is formed by the spatial distance of the rubber cylinder axis 23 from the rubber cylinder bearing 24, is firmly connected to an adjustment segment 41, which is part of an adjustment mechanism 4.
  • the adjustment segment 41 has a toothing 45 on its outer contour. This toothing 45 engages in the toothing of a gear pinion 42, which in turn has a Rack 44 combs.
  • the contact gear pinion 42 / rack 44 is by a roller 43 maintained.
  • the rack 44 is articulated to the piston rod 51 of an adjusting cylinder 5.
  • the adjusting cylinder 5 is articulated in a frame point 53 at its articulation point.
  • FIG. 2 The storage of the rubber cylinder 2 and in particular the connection between the drive of the rubber cylinder and the rubber cylinder axis 23 is shown in FIG. 2. It's closed recognize that the interacting with the impression cylinder 1 and plate cylinder 3 Rubber cylinder 2 is mounted with its rubber cylinder axis 23 in the housing wall 6. The takes place via the eccentric bushing 25, which is assigned to the rubber cylinder axis 23 via bearings 61 is.
  • the rubber cylinder axis 23 is fixedly connected to an output member 83, which is part of a Oldham clutch 8 is.
  • the Oldham coupling 8 also consists of a drive member 81, which is assigned to the output member 83 via an Oldham ring 82.
  • the drive member 81 is non-rotatably connected to a drive shaft 27, which in turn is rotatably connected to a rubber cylinder drive wheel 26 is connected.
  • the rubber cylinder drive wheel 26 meshes with a plate cylinder drive wheel 36.
  • rubber cylinder drive wheel 26 and plate cylinder drive wheel 36 are part of a drive wheel train starting from the plate cylinder 3.
  • the Oldham clutch is enclosed in a clutch housing 7.
  • bearings 61 are arranged for receiving the drive shaft 27.
  • an Oldham coupling 8 has been proposed. This belongs to the cross disc couplings. It is also possible to use other suitable axial compensating couplings use.
  • the eccentric bushing is used to adjust the position of the rubber cylinder 2 to adjust the pressure 25 rotated by the device shown in Figure 1.
  • the adjusting cylinder 5 actuated and thus changed the position of the piston rod 51 with the rack 44. This leads to the rotation of the adjustment segment 41 via the gear pinion 42 is due to the eccentric mounting of the rubber cylinder axis 23, this from the Position A, position 23a (no contact with the plate cylinder 3 and impression cylinder 1) Position B, position 23b (contact with the plate cylinder 3). Turning further to the position C, layer 23c, the rubber cylinder 2 comes to rest against the plate cylinder 3 and Impression cylinder 1.
