Definitions

  • Such a device is known for example from EP 0955161 A2.
  • This document shows an inking unit in which the motors which rotate the spindles and in the manner described above apply the force necessary for position adjustment, are mounted on the opposite side of the counter-pressure roller rollers involved in color transport on the machine frame.
  • devices are known in which the motors which allow the position adjustment of the plate roller, on the counter-pressure cylinder side facing the inking unit, while the motors which move the anilox roller, on the side facing away from the impression cylinder side of the two rollers involved in color transport are provided.
  • the vertical spacing of the guides allows easier positioning of the spindles in the inking unit.
  • the inventive compact design of the inking unit also leads to a reduction of the vibrations to which the rollers are exposed during the printing process.
  • machine frame means any machine components suitable for fastening the motors.
  • the figures show an embodiment of a Competitionwerkes 3 according to the invention, in which the cliché roller 20 associated adjusting elements 21, 22, 23, 24, 25 are mounted below the plate roller 20, while the anilox roller 10 associated adjusting elements 11, 12, 13, 14, 15th are arranged above the same 10.
  • the anilox roller 10 the axle bearing bearing block 15 and the carriage 14 is mounted on the bearing block 15, suspended from the rail 13.
  • the movement of the carriage 14 in the direction outlined by the arrow A is carried out by the motor 11, the spindles 12, which pass through existing in the bearing block 15 internal thread 17 rotates.
  • the axis of the plate roller 20 of the bearing block 25, which is angeacht on the carriage 25, worn are analogous to the structure of the adjusting device 11, 12, 13, 14, 15 of the anilox roller 10, the axis of the plate roller 20 of the bearing block 25, which is angeacht on the carriage 25, worn.
  • FIG. 1 illustrates that the free path length of the two spindles 12, 22 between the respective bearings 16, 26 of the spindles 12, 22 and the respective bearing blocks 15, 25 is minimally adjustable in this position in devices according to the invention.
  • FIG. 2 shows a section through the inking unit shown in FIG. 1 along the section line CC.
