Definitions

  • the invention relates to a printing unit of a rotary printing press according to the preamble of claim 1.
  • a device which moves the bearing block of the forme cylinder, which is mounted on a longitudinal guide, by means of a controlled axis to adjust the side register.
  • These controlled axes are known to be very expensive and expensive.
  • the present invention has set itself the task of creating a printing unit, which allows a simple yet accurate adjustment of the side register and also allows a fast larger axial movement of the forme cylinder for decoupling purposes.
  • the bearing block is due to the contact pressure of the fluid-operated cylinder working at the adjustable stop. Due to the adjustable stop the form cylinder is moved over its bearing blocks and thus regulated with the adjustable stop and with the aid of a controller and a scanning optics in the form of a camera, the page register. The fluid-operated cylinder moves on the drive-side mounting the forme cylinder in the coupling movement.
  • the previously set positions of the axial register or page register in contrast to a device for adjusting the side register with a controlled axis, remain in a decoupling of the forme cylinder. After completion of the coupling movement, a controlled axis would have to approach the previously set positions again with the required accuracy. This costs time or increases the time required for coupling and exact positioning of the forme cylinder at preset positions.
  • the present inventive device has a positioning drive, which can perform at different speeds required for the correction of the page register positioning and thus is able to use larger positioning speeds in large necessary procedures. Since with large register deviations the printed copies must be classified as bad, a large positioning speed for the printed image is not disadvantageous. It is significant, however, that by means of a large positioning speed, the time for the correction of the register deviation, in particular the compensation of the deviation of the page register, is considerably shortened. Furthermore, the harmless for the print image positioning speed depends on the speed of the plate cylinder. The faster it turns, the faster it can be positioned.
  • the Fig. 1 shows a printing press, consisting of a paper roll changer 1, double printing 2 to 5, a dryer 6, a cooling unit 7 and a further processing 8, for example, a folder.
  • Each of the double printing units 2 to 5 has two forme cylinders 9 and 10 and two transfer cylinders 11 and 12, respectively.
  • the transfer cylinders 11; 12 transmit that on the form cylinders 9; 10 existing colored print image on a paper web 13, which is thus printed on both sides four-color when going through in the direction 14.
  • the register control on the circumference of the forme cylinder 9; 10 takes place via the drive, in particular via individual drive motors, the register control of the forme cylinder 9; 10 in the axial direction, ie the regulation of the page register, will be described in more detail below.
  • the structure of the form cylinder storage is based on the Fig. 2 and Fig. 3 shown.
  • the forme cylinder 10 is rotatably mounted in bearing blocks 17 and 18 and is driven by a drive 19, for example an electric motor.
  • the support of the cylinder on the bearing block 18 between the cylinder axis 20 and spindle axis 21 is releasable on a cone 22 via a screw 23.
  • the bearing block 17 is mounted on guides 24 and the bearing block 18 on guides 25.
  • the bearing block 17 in the direction of 26 and 27 and the bearing block 18 in the direction 28 and 29, respectively.
  • the bearing block 17 is designed as a fixed bearing, the bearing block 18 as a movable bearing, which allows a certain displacement in the directions 26 and 27.
  • FIGS. 5 and 6 show now in enlarged detail the Figures 3 and 4 as the register adjustment, ie the means for adjusting the side register of the forme cylinder 9; 10 is connected to this coupling movement.
  • a gear 45 consisting of a housing 33 and spur gears 34 and 35, is fixedly connected to the fluid-operated cylinder 30 and is supported on this on the stationary machine frame 31 from.
  • a bolt 36 is screwed in the bearing block 17 and is supported with its head 37 on the spur gear 35 from.
  • the working cylinder 30 presses the function of the side registering, ie force or Anstelldruck of the working cylinder 30 in the direction 27 - Anstellraum -, the bearing block 17 via the pivot bearing 32 in the direction 27 and thus brings the head 37 on the spur gear 35 without play to the plant.
  • This spur gear 35 can be moved axially when turning over an example configured as a fine thread in the housing 33 arranged threaded 38, ie in the direction 26 and 27 by the pressure of the working cylinder 30 in the direction 27, the flanks of the thread 38 are pressed together without play. Each rotation of the spur gear 35 is thus immediately and without play in an axial movement of the bearing block 17 and the forme cylinder 9; 10 implemented.
  • the spur gear 35 is first rotated by the servomotor 39 at a high speed to shorten the travel time. From this high rotational speed results in a high speed, a so-called. Positioning, the axial movement of the bearing block 17. With increasing rotation of the spur gear 35 is the Page registers corrected, ie the deviations of the registration marks are reduced, so that the traversing path to be covered for correcting the register deviations becomes smaller. Thus, the speed of rotation of the spur gear 35 is reduced due to the registered reduced deviations of the registration crosses and the reduced travel path.
  • the high speed of rotation of the spur gear 35 at the beginning of the correction of the side register, due to the high deviations of the register marks, is thus gradually reduced as a result of the increasing improvement of the side register until the final correction of these register deviations.
  • the speed of the servomotor 39 is thus variable and / or different adjustable.
  • the center position of the spur gear 35 is registered via a switch 40, the end positions of the travel from the non-contact switches 41 and 42.
  • the spur gear 35 thus represents an adjustable stop.
  • the device should not be limited only to the use of form cylinders. It is also possible to apply the device in addition to transfer cylinders to perform a quick cylinder change or quick change arranged on the transfer cylinder blanket cylinder sleeve.
  • the object is achieved, a simple, accurate Axialregisterung with a fast coupling movement of the cylinder, in particular the forming or transfer cylinder to connect.
  • the before adjusted positions of the axial register remain, unlike a controlled axis, received.
  • a controlled axis would have, after completion of the coupling movement, the previously set positions again approach with the required accuracy, which costs time.
  • variable speed for correction of the register deviations should not be limited to a servomotor. It is also possible according to the DE 100 08 215 A1 used controlled axis, such as a motor-driven spindle or a linear drive to operate for correcting the side register with variable and / or different speeds.
