Definitions

  • the invention relates to a method and a device for coupling / uncoupling a cylinder according to the preambles of the main and secondary claim.
  • the cylinder can be releasably connected on the drive side by means of a clutch formed from a first and a second clutch disc.
  • the first clutch plate is connected in a torsionally rigid manner to the drive wheel and the second clutch plate is connected in a torsionally rigid manner to the cylinder journal.
  • Both clutch disks are axially displaceable relative to one another by means of a working cylinder that can be pressurized.
  • the working cylinder is subjected to a lower pressure than the final pressure prevailing in the coupled state during the coupling process.
  • the first clutch disc is functionally connected to a control valve, wherein this control valve can be actuated by the second clutch disc in such a way that the control valve carries a pressure medium when it is coupled into the working cylinder and the control valve is closed in an engaged state.
  • a hollow shaft is axially rigidly rotatably supported in the bore and a selector shaft is axially rigidly and rotatably supported in this hollow shaft and a selector shaft is axially displaceably arranged in this hollow shaft, the shift shaft and the associated cylinder journal being connected in each case by means of coupling halves.
  • the drive wheel is fastened to the hollow shaft and another clutch, which compensates for the axial offset, is arranged between the hollow shaft and the shift shaft without play.
  • the hollow shaft has an internal toothing and the selector shaft is designed with two external toothings which can be rotated relative to one another and interact with the internal toothing.
  • a device for connecting / disconnecting a roller body in a printing press is known.
  • the rollers and bearings are coupled by axially displacing a bearing pin using a clamping spindle penetrating the roller body.
  • the clamping spindle can be screwed into the first bearing journal on one side, a clamping screw penetrating a second bearing journal on the other side and being screwable into the clamping spindle.
  • the end of the roller body has fitting bores for receiving the bearing pins, compression springs being arranged in the fitting bores and being able to be connected to the roller body by actuating the tensioning screws of both bearing pins against the spring force.
  • the disadvantage here is that all versions are relatively complex.
  • the object of the invention is to create a method and a device of the type mentioned at the outset which avoid the disadvantages mentioned, which in particular simplify the coupling process of the cylinder and bearing including the drive and allow a shortening of the set-up times.
  • the object is achieved by the training features of the main and secondary claims. Further training results from the subclaims.
  • a first advantage of the solution according to the invention is based on the fact that the coupling process can be automated. As a result, a noticeable reduction in set-up time can be achieved when changing a cylinder in a printing press.
  • the drive of the cylinder remains stationary in the printing press when coupling or uncoupling.
  • the coupling process thus avoids possible wear-promoting effects on the drive or the bearing.
  • Another advantage is due to the fact that the cylinder is designed with or without a pin. It is not necessary to insert the pins into the side frame. This makes it easier to insert or replace the cylinder between two side frame walls, regardless of whether this is done manually or automatically, for example by means of a magazine and / or handling device, for example an industrial robot.
  • a change (coupling / uncoupling) of the cylinder can be carried out manually or automatically.
  • an automated change of the printing / coating form can be carried out on printing and / or coating units, while preferably an automated change of cylinders or rollers in the bearing bushes takes place at the same time.

  • Fig. 6 is a section A-A of Fig.5.
