Definitions

  • the invention relates to a rotary printing press with one or more impression cylinders and with several printing units, each with an inking unit and an endless cliché belt, which runs over several rollers, one of which can be adjusted to the associated impression cylinder.
  • the endless cliché belt runs over a master cylinder which can be adjusted to the impression cylinder and a guide cylinder which is adjustable in order to be able to change the format sizes by placing longer or shorter cliché belts.
  • a rotary printing press is provided with several printing units, it is desirable that the distance from the ink cylinder to the impression cylinder measured on the cliché tape is always the same, in order to avoid dirty printing due to different drying of the inks.
  • the object of the invention is therefore to provide a rotary printing machine of the type specified at the outset, in which the distances between the inking roller and the impression cylinder measured on the cliché belts are always the same.
  • this object is achieved in that the cliché belt of each printing unit runs over four rollers which are mounted in side view in the corners of a square or parallelogram and of which two diametrically opposed rollers can be set against the inking unit or an image carrier web and against the impression cylinder and the other two diametrically opposite rollers are mounted in guides and can be moved towards and away from one another by drives.
  • the respective length of the printing plate section between the roller set on the inking roller and the roller set on the impression cylinder is always the same, so that the colors are applied with the same amount of drying.
  • the center lines of the bearings of the rollers in side view span a parallelogram with sides of the same length or of different lengths.
  • rollers are mounted in lateral, rigidly connected bearing plates which are non-rotatable with respect to the printing unit frame or the printing unit carriage, but are laterally displaceable.
  • a device which laterally adjusts the bearing plates can be provided for simple adjustment of the side register.
  • a gear wheel is arranged axially displaceably but non-rotatably on a shaft journal of one of the rollers, with the helical toothing one or the counter-pressure cylinder driving the central gear that a bush fixed on a frame-fixed pin but non-rotatably but axially displaceably and connected with a finger or a washer which engages in an annular groove of the hub of the gear, and that an adjusting device for axially displacing the bushing is provided is. If the bushing is adjusted in the axial direction by the adjusting device, the longitudinal register can be adjusted because a displacement of the gear wheel driving the roller on the shaft journal causes the roller to be turned forward or backward accordingly.
  • a format wheel is expediently rotatably but axially immovably mounted on the bushing, which meshes with the central wheel and the ink cylinder drive gearwheel and whose hub carries the disk which engages in the annular groove of the hub of the gearwheel.
  • a printing press with a ge in a frame 2 stored impression cylinder 1 is shown, the total of six printing units 3 are assigned.
  • the impression cylinder 1 serves as a common impression cylinder for all printing units 3.
  • Fig. 2 also shows a frame 2 ', which carries a total of six printing units 3'.
  • each printing unit 3 ' here is assigned a separate impression cylinder 1'.
  • Each printing unit 3 or 3 uses a plate 4 as a pressure transmitter, which loops around a total of four rollers, namely an upper and a lower tensioning roller 5, 6 and two printing rollers 7, 8.
  • all Rollers 5 to 8 are mounted in two side plates 9 and 10 which are arranged parallel and at a distance from one another.
  • the rigid connection between the plates 9 and 10 takes place via four round traverses 11.
  • pins 12 and 13 the two plates 9 and 10 are non-rotatable but laterally displaceable in the side walls 15, 16 of the format cylinder slide 17.
  • a bushing 18 is firmly placed, in which the adjusting member 19 engages for the motorized side register adjustment device, not shown.
  • a bushing 20 is non-rotatably but laterally displaceable. This side shift occurs via an actuator 21 of a motor-operated longitudinal, not shown register adjustment device.
  • the format wheel 23 is placed on the bushing 20 via a bearing 22. This format wheel 23 meshes with the central wheel 24, the diameter of which corresponds to the diameter of the impression cylinder 1 and is firmly connected to the latter.
  • the toothing of the central wheel is helical.
  • a further gear wheel 25 meshes with the central wheel 24.
  • This gear wheel 25 has an attachment 26 provided with an annular groove, a disk 27 engaging in the annular groove, which is firmly connected to the format wheel 23.
  • the actuator 21 is used for the longitudinal register adjustment in that it also adjusts the format wheel 23 with the bushing 20 and with this the gear wheel 25 in the axial direction, which is non-rotatably but axially displaceably arranged on the shaft journal 28 of the pressure roller 7. If the gear 25 is displaced in the axial direction, this gives the pressure roller a rotation because the gear 25 is in engagement with the central gear 24 by means of helical teeth.
  • lateral dots on the cliché band 4 indicate that this band is toothed on its back.
  • the tensioning rollers 5 and 6 can consequently be shifted by the same amounts relative to one another. This is necessary for tensioning a cliché tape or to ensure the use of cliché tapes of different lengths.
