Definitions

  • a determined between two decoupled groups of printing groups Speed difference during the acquisition balanced the Gripper system on the first transfer cylinder of the receiving printing group parallel is moved to the cylinder surface.
  • a misalignment of the sheet will be on the first transfer cylinder of the acquiring printing group by the gripper system corrected by being parallel to the cylinder surface and axially in the direction of Cylinder axis is moved.
  • a variant of the method is provided by the fact that the dynamic Control device before the transfer of the sheet, the operating parameters of Print groups preferably detected by sensors, speed differences determines and compensates the compensation elements during the transfer controls. As well the position of the sheet after the takeover on the first transfer cylinder is the recorded group of compressors and the compensation elements after the Correcting takeover controls.
  • Figure 2 shows a coordinate representation of the speeds of the printing groups II and III on the machine angle in degrees.
  • the curve n 1 represents the rotational speeds of the printing unit group II of FIG. 1.
  • the curve n 2 represents the rotational speeds of the printing group III of FIG. 1.
  • the rotational speeds of the printing group II, n 1 varies with respect to the rotational speeds of the printing group III, n 2nd ,
  • the task of the compensation means 15 consisting of a dynamic actuator 16 and a gripper system 17, 18 can be seen.
  • the actuator 16 compensates for the speed difference between the groups of printing groups II and III. This takes place during the transfer from the gripper system 17 of printing group II on the gripper system 18 of printing group III. For this purpose, a displacement of the actuator 16 and thus of the gripper system 18 by the phase difference A 1 . At point 21, the transfer of the sheet takes place.
  • Section III the actuator 16 is held in a rest position. At point 22, the Printing sheet from the second cylinder 19 of the printing group III phase corrected accepted.
  • the second cylinder 19 is in the representation as the first impression cylinder the printing unit group III shown.
  • the electronic measuring elements for example also illuminable CCD line, arranged on at least one axial end of the transfer cylinder 13.
  • the latter CCD lines are format-dependent adjustable, as it is known, and control via a data processing means of the control device 14, as shown in FIG. 1 shown, the actuators for the displacement of the gripper system 18 on the carriage in the direction of the cylinder axis.
  • the actuators for the displacement of the gripper system 18 on the carriage in the direction of the cylinder axis By way of a target-actual comparison are from the Measured values of the electronic measuring elements on the gripper pad 26 by the Control device 14 control pulses for the actuators for position correction in Conveying direction of the printed sheet and by the electronic measuring elements on the Axial cylinder end control signals for the lateral position correction of the sheet won.
  • Figure 6 shows a schematic representation of cylinders in the transfer of a Sheet.
  • the cylinders are between two groups of printing groups II, III so arranged that the transfer error compensation can be made according to the invention.
  • the Print groups II and III are decoupled. The decoupling is through the level 11 shown.
  • the signature is from the gripper system 17 of the last sheet-leading Cylinder of printing group II, which is shown as a counter-pressure cylinder 12 at passed the Grci Fersystem 18 of the transfer cylinder 13 of the printing group III. Thereafter, the sheet from the first transfer cylinder 13 of the printing group III the second cylinder 19 passed, which as the first impression cylinder of the Printing group III is shown.
  • the printed sheet is transferred to the before Gripper system of the second cylinder 19 of the acquiring printing group III only fixed to a point. In this position, therefore, the position compensation of the sheet on cheapest.
