Definitions

  • the invention relates to a method and a device for the automatic turning on and off of the sheet turning when transporting sheets through a printing press, in particular the conversion of the transport drums or cylinders between two printing units from straight printing to face and back printing and back again.
  • Printing machines are known for printing sheets on both sides in one pass, in which a sheet turning device is provided between two printing units, which is turned off in the straight printing mode and which is employed in the perfecting mode. (DT 24 19 747 C3, DE 39 11 609 A1, DE 39 20 821 A1, DE 39 11 630 A1, DE 39 00 818 C1, DE 38 14 831 C1, DE 24 60 503 A1)
  • German patent DE 24 60 503 C3 describes a printing press with a changeover and setting device, in which in straight printing operation the sheet is taken over from the previous printing unit with the grippers of a transfer drum on its front edge and to a first of two gripper systems, one in diameter double the storage drum is passed on its front edge. The storage drum again transfers the sheet at its front edge to the grippers of a third drum, which acts as a reversing drum in the perfecting mode. All transport drums run synchronously, which is achieved with a drive via a closed gearwheel train or a drive with several mechanically decoupled, speed-controlled motors. The gripper systems of the individual transport drums are cam-controlled, whereby different gripper opening curves are used in straight printing and in finishing and reverse printing.
  • the leading edge of the sheet is guided past the reversing drum with the gripper system of the storage drum.
  • the trailing edge of the sheet is then gripped by the gripper system of the third drum, the gripper system of the third drum executing a 180 ° pivoting movement and the gripper system of the storage drum releasing the leading edge of the sheet.
  • the rear edge of the turned sheet is passed on to the subsequent printing unit for printing on the second side.
  • a first step the transport drums must be brought into a defined changeover position, which is referred to below as the zero position.
  • the zero position is started by hand or via the drive of the printing press or via additional adjustment drives. Reaching the zero position is visually checked by means of marks or scales or recognized by sensors which emit a corresponding zero position signal.
  • DE 38 36 310 A1 describes an arrangement for controlling switching operations on a printing press, in which an incremental angle encoder is coupled to the gear drive that drives the transport drums, the angle encoder per revolution a defined number of angle pulses and a single one Emits a zero pulse, the leading edge of which is used as a zeroing signal.
  • the phase position of the printing units relative to one another is adjusted by holding a part that is not to be rotated in the drive system of the printing press and rotating the remaining part of the drive system by a defined angular amount relative to it.
  • a wide variety of barriers or ratchets are used to hold on.
  • the main drive of the printing press or an additional adjustment drive can be used as the adjustment drive.
  • the gripper opening times of the sheet-receiving and the sheet-transferring transport drum are adjusted by first loosening the grips of the gripper control elements and the gripper curve and moving the gripper control elements of the turning drum and rotating the gripper curve of the storage drum by means of separate drive elements.
  • the devices that hold the trailing edge of the sheet can be adjusted to the trailing end of the respective sheet in accordance with the format by releasing the hold between them and by rotating them relative to the grippers holding the leading edge of the sheet a common axis can be adjusted by a defined angle.
  • All actuating elements for the fixings and all drive elements for elements to be adjusted and all sensor elements for detecting the position of the elements to be adjusted are connected to a control device which controls the exact positioning.
  • the object of the invention is to provide a method and a device for turning the sheet turning on and off, which include simple stationary pressure control elements and shorten the changeover times.
  • the object is achieved in that the adjustment of the phase position of the printing units, the gripper opening times and the elements holding the front and rear edge of the sheet takes place at the same time to one another by working through the method steps listed in claim 1.
  • the device includes a pressure-medium-actuated clutch between means for adjusting the gripper control elements of a storage drum and drive means for adjusting the phase position of the printing units relative to one another, the actuating elements of the clutch being connected to a control part for pressure-medium-actuated actuators of a control device.

  • the working cylinders of the actuators actuated by pressure medium are arranged in a manner fixed against relative rotation to the machine frame of the printing press, so that the device does not require any costly and unreliable rotary unions for supplying the pressure medium.
  • the changeover time in the changeover between face printing and fine and reprinting can be shortened because all the adjustment processes required for this take place essentially at the same time.
  • the adjustment of the elements of the storage drum holding the leading edge of the sheet and the trailing edge of the sheet to the corresponding sheet format can be carried out in face and reverse printing operations or also in straight printing operations.
