Definitions

  • the invention relates to a drive for a printing press, in particular sheet-fed offset printing press according to the preamble of claim 1.
  • Sheet-fed offset printing machines of the more widespread type have a main drive in particular in the form of a DC motor, which holds the cylinders of the printing units as well the cylinders / drums used for sheet transport via a continuous wheel train drives.
  • a main drive in particular in the form of a DC motor, which holds the cylinders of the printing units as well the cylinders / drums used for sheet transport via a continuous wheel train drives.
  • This train of wheels especially when there are a large number of printing units very large load moments, which cause torsion between the individual printing units cause.
  • load changes there are doubling phenomena or Registration differences.
  • the drive of a sheetfed offset printing machine with a feed point by means of a drive motor also has the disadvantage that, for example, when changing the operating mode from beautiful to beautiful and reverse printing and vice versa to separate the gear train is what makes complex mechanical components necessary.
  • a drive for a printing press in which the Influence from the drive train of all those not used to promote the printing material Items to reduce synchronicity.
  • a first drive one or more Drive motors
  • the elements that are not used to transport the printing material as in particular the inking and / or dampening units have their own drives, whereby the drive of these elements is position-controlled to the cylinder. So it happens a synchronization of the decoupled subsystems by signals of movement quantities control systems.
  • DE 42 14 394 A1 discloses a rotary printing press with a number of individually driven ones Cylinder and at least one separately driven folder known which combines the individual drives of the cylinders and their drive controllers into pressure point groups are.
  • the individual pressure point groups are assigned to one of the folders, which obtain a position reference from this folder.
  • the administration of the Pressure point groups are created by a superordinate control system.
  • a sheetfed offset press also has to take precautions to avoid that the gripping devices have sheet-guiding cylinders (Impression cylinder, sheet guiding cylinder / drums) by a maximum permissible Angular amount can be rotated relative to each other, otherwise the protruding from the circumference of the pitch circle Equipment of the gripper systems would be damaged.
  • sheet-guiding cylinders Impression cylinder, sheet guiding cylinder / drums
  • EP 0 355 442 B1 describes a method and a device for reducing the Torque loading on a system driven by an electric motor is known.
  • changes in the load torque are caused by opposite changes counteracted the drive torque, such that the load torque to approximately constant value is kept.
  • a sheetfed offset press with several Printing units and a drive motor controlled in this way can, however, be used Only minimize torsion generated by the load fluctuations, with no gain Functionality is achieved.
  • DE 42 28 506 A1 describes a method and a drive for a printing press known several printing units, in which several drive motors have a continuous gear train float.
  • a first drive motor feeds excess power into the gear train one that is sized so that a constant direction of power flow in the gear train is ensured.
  • a last drive motor compensates for this excess power, brakes so the gear train.
  • This procedure and the appropriate drive can Tooth flank changes that lead to uncontrollable tension can be avoided.
  • a disadvantage of this method is that the angular position of the feed motors or cylinder driven by the motors is undefined, which means that the angular position strongly depends on the phase and tolerance of the gears.
  • the object of the following invention is therefore a drive for a printing press, in particular Sheet-fed offset printing machines according to the preamble of claim 1 expand so that avoiding the disadvantages mentioned above Printing process improving and inexpensive drive is obtained.
  • the drive to be created should in particular increase the functionality of the printing press cause.
  • the blanket cylinder in a multi-color offset printing press Sheetfed offset printing machine the blanket cylinder, the impression cylinder as well the sheet-guiding cylinders arranged between the impression cylinders or
  • Drums are coupled together by a gear train.
  • the drive of this cylinder system takes place by means of position-adjustable drives assigned to the individual blanket cylinders, the setpoint specifications for the drives driving the blanket cylinders by in each case an angular offset is chosen offset from one another. So it comes to ground these setpoints due to the elasticity of the gear train and the existing tolerances to a defined tension in the gear train between the printing units.
  • the Angular offset between two successive blanket cylinders is such dimensioned that in the intermediate train (impression cylinder, sheet leading Cylinders or drums) the backlash is moved out at every angular position.
  • the offset is dimensioned by one turn constant backlash also according to the rolling tolerance and the disturbance torques in the gear train between two blanket cylinders.
  • the offset can be done on any sheetfed offset press according to the recorded rolling tolerances individually from the printing unit Printing unit set and each stored as a specific value in the control electronics become. It is also possible to have a uniform, sufficiently large one for each machine To determine and specify the offset value.
  • the blanket cylinders real or virtual drives assigned to the individual printing units Master axis (appropriately trained setpoint generator) can be generated. It is so in particular possible that, for example, on the first printing unit (blanket cylinder) a position encoder is arranged, the actual position values of which are fed to an evaluation and control circuit. This now generates the corresponding position setpoints for the drive of the blanket cylinder in the first printing unit, around the machine according to a predetermined speed setpoint to drive. The evaluation and control circuit generates the actual position values this position encoder the position setpoints for the drives of the blanket cylinders in the second and subsequent printing units.
  • the position setpoints for the drives of the blanket cylinders in the following Printing units always with the same or different from printing unit to printing unit selected angle offset, so that it to that mentioned above There is tension in the gear train.
  • a position setpoint control which is a real movement of a cylinder follows
  • the principle of a virtual master axis control can also be implemented, in that that the drives assigned to the individual blanket cylinders according to a predetermined Command (e.g. speed to be driven) is charged with calculated position setpoints become.
  • a predetermined Command e.g. speed to be driven
  • the position setpoints for the first for example Printing unit following drives the blanket cylinder in the other printing units always with an additional offset, so that it leads to a defined tension in the wheel train enclosed between two blanket cylinders is coming.
  • the position setpoints given by the controller assigned to the drives are generated by a virtual leading axis in this embodiment.
  • the plates or forme cylinders each have their own position-controlled drive in the individual printing units and run mechanically decoupled from the respectively assigned blanket cylinders.
  • the plate cylinders independently of those using the blanket cylinders driven printing units. So the printing forms / printing plates in the individual printing units with corresponding exchange devices changed simultaneously be or it is possible to simultaneously the printing plate / printing plate change process an automatic washing program for the blanket cylinders / the impression cylinders to expire.

  • the four printing units of the sheet-fed offset printing press shown in the figure include Plate cylinder PZ, blanket cylinder GZ and those interacting with the blanket cylinder GZ Impression cylinder GD. Between the impression cylinders GD the individual printing units are arranged transfer drums T. The blanket cylinders GZ, the impression cylinders GD and those downstream of the impression cylinders GD Transfer drums T are coupled to one another via a mechanical gear train.
