Definitions

  • FIG. 2 is a schematic representation of a gripping and pressing device of the device according to the invention from FIG. 1,
  • FIG. 3 shows schematic side views of the device according to the invention with associated FIG. 11 cylinders and provisioning devices in different working positions
  • This synchronization can take place mechanically, for example, via chain or cardan shafts or electronically via two separate drives 38 of the linear drives 27, 28.
  • the two threaded spindles 29, 31 move one parallel to the axis of rotation 18 of the cylinder 1 Traverse 39 in a transport plane 41 which is above and approximately. is parallel to the tangent 21 determined by the cylinder jacket surface 22 of the cylinder 1 and the mounting strip 19 of the printing plate preparation device 12.
  • At the two ends of this cross member 39 there are threaded nuts 42 so that the cross member 39 is at right angles to the threaded spindles 29, 31 in operative connection.
  • At least one gripping and pressing device 43 is attached along this traverse 39; in the example shown, four gripping and pressing devices 43 are fastened.
  • a gripping and pressing device 43 consists of at least one gripper unit 44 and at least one pressure roller 46.
  • This gripper unit 44 and the pressure rollers 46 are "D” in the radial direction with respect to the cylinder 1, the gripper unit 44 additionally still in the axial direction "C", independently of one another by means of positioning devices.
  • the new printing plate 84 to be applied was placed in a pre-positioned manner on the upper wall 13 and on the hanging bar 19 of the printing plate preparation device 12.
  • the pressure plate 84 is held by the suction strips 47, by actuating the pneumatic cylinder 53 with a fixed force, for example sprung, axially positioned at a respective side register stop 86, parallel to an axis of rotation 18 of the cylinder 1, so that the pressure plate 84 rests securely on the side register stop 86 , but is not deformed.
  • the spring force for positioning the pressure plate 84 can be generated, for example, by the spring of a single-acting pneumatic cylinder 53 or by the air pressure (for example adjustable via pressure regulator) of a double-acting pneumatic cylinder.
  • the side register stops 86 are arranged on the mounting rail 63 of the cylinder 1 below the cylinder surface 22 in a cylinder-fixed manner.
  • the shaft 16 of the first provision device 12 receives a second, used printing plate 2 in accordance with the described first disassembly process.

Abstract

Dans un dispositif pour le montage, le démontage et le transport d'objets courbés pliables pourvus d'arêtes d'accrochage, en particulier de plaques d'impression, il s'agit de positionner axialement avec précision ces objets courbés pliables sur le cylindre et d'assurer une bonne accessibilité aux groupes d'impression. Selon l'invention, cela résulte d'un mouvement élastique exécuté sous l'action d'un cylindre pneumatique, et la position de repos du dispositif de maniement se trouve à proximité du cylindre.
