Definitions

  • the invention relates to a printing unit for a web-fed rotary printing press with a plurality of printing unit cylinders each having its own drive motor, which can be adjusted to one another by means of a carriage guide.
  • the invention has for its object to provide a generic printing unit with a simple, inexpensive construction and narrow width, in which the transmission of vibrations that are excited by a printing cylinder, on other printing cylinder over the means for adjusting the carriage is avoided and long carriage guides for wide slide can be realized.
  • the printing unit shown has a trained as a wall or truss supporting wall 1, are guided on the same trained carriages 2 to 5.
  • the same design of the carriage 2 to 5 brings a manufacturing simplification.
  • Each carriage 2 to 5 carries a printing cylinder 6 to 9 and takes a drive motor, not shown here for its printing cylinder on.
  • the support wall 1 is arranged laterally next to the end faces 11 of the printing cylinder 6 to 9.
  • drive motors of the aforementioned type are shown.
  • FIG. 2 shows in particular, a wall 10 of the supporting wall 1, which runs perpendicular to an imaginary plane laid on the end face 11 of the printing cylinder 9, carries two guide elements 12, 13 for guiding the carriage 5.
  • the straight guide elements 12, which are rail-shaped here , 13 here have a T-shaped cross-section to create a positive carriage guide.
  • the crosshead of each T-shaped cross-section engages in a correspondingly formed undercut groove 14 on the carriage 5 a.
  • a further wall 15 is provided on the support wall 1, which also carries rail-shaped, straight guide elements 16, 17 carries T-shaped cross-section.
  • On each of the two walls 10, 15 is still a threaded spindle 18 to 21 for each printing cylinder 6, 8 and 7, 9 rotatably mounted, but axially immovable.
  • the identically designed guide elements 12, 13, 16, 17 and the threaded spindles 18 to 21 are positioned so that the carriage 3 and 5 for the printing cylinder 7 and 9 on the wall 11 and the carriage 2 and 4 for the printing cylinder 6 and 8 are guided on the wall 15.
  • the carriages cooperating with each other, i. successive printing cylinder are thus arranged alternately on the opposite walls 10 and 15 respectively.
  • Each threaded spindle 18 to 21 engages in an indicated in Figure 1, fixedly arranged in each carriage 2 to 5 threaded nut 18a to 21a. On the one end of each threaded spindle 18 to 21 is firmly attached to a gear 22 to 25.
  • Each gear is connected via a countershaft 26 to 29, for example in the form of a chain or belt drive with another gear 30 to 33 in connection, which is mounted on the output shaft of a mounted on the support wall 1 servo motor 34 to 37.
  • the actuators are expediently designed as electric motors, which are hardwired to the support wall 1. Instead of a chain drive could, as mentioned, also find a belt drive with internal teeth use.
  • Figure 1 shows the printing cylinder 6 to 9 in the print-on position.
  • the printing cylinder 6 and 7 in Figure 1 so up and the printing cylinder 8 and 9 so moved down in that all the cylinders are lifted apart from one another, as indicated by broken lines in FIG.
  • the servomotors 34 to 37 which may be designed, for example, as stepper motors, the pressure on and off positions and the positioning of the printing cylinder 38 to 41 described below can be realized in a format change.
  • FIG. 3 shows that the carriages 2 to 5 can also be equipped with printing cylinder cylinders 38 to 41 of smaller diameter.
  • the invention therefore offers the further, very particular advantage that printing units with printing cylinder cylinders of different diameters can be designed with the carrier wall 1 of the same design and carriages and slide guides of the same design.
  • the guide elements 53, 54 of the two slides 42, 43 for the inner printing cylinder 44, 45 on a wall 46 and the guide elements 55, 56 of the two slides 47, 48 for the two outer printing cylinder 49, 50 at the parallel opposite wall 51 of a support wall 52 is arranged.
  • the drive for the carriage 42, 43, 47, 48 is the same as in the first embodiment and therefore not shown.
  • the slides 42, 43 assigned to the inner printing unit cylinders 44, 45 must be exchanged for higher ones.
  • the carriages 47, 48 associated with the outer printing unit cylinders 49, 50 can be retained. In this way, it is ensured that the imaging cylinders formed as forme cylinders 49, 50, indicated at 57, 58, whose optical axis should be coplanar with the axis of the associated forme cylinder, are not adjusted with respect to the distance from the guide elements 55, 56 have to.
  • the imaging devices since the imaging devices may be equidistant from the guide members 55, 56, the imaging devices 57, 58 may be stationary.
  • the imaging devices can also be movable so that they can approach the respective associated cylinder. It is expedient if the imaging device with respect to the associated forme cylinder 49,50 in the direction of movement is movable. On the other hand, the arrangement is suitably made such that the forme cylinder 49, 50 can be moved relative to the imaging device in its working direction, that is to say the direction of the imaging.
  • the imaging devices 57, 58 for this purpose on the guide elements 55, 56 of the respective associated cylinder 49, 50 movable.
  • the guide elements 55, 56 expediently extend to the imaging devices 57, 58.
  • additional devices or auxiliary devices required for printing such as inking and / or dampening units, as explained above for the imaging devices, on the guide elements 55, 56 movable and thus arranged to be approached to the associated cylinder.
  • the traversable auxiliary means are suitable drive means in the form of e.g. Assigned servomotors.
  • the mobility of the form cylinder 49, 50 on the auxiliary equipment, such as here the imaging devices 57, 58, and the latter on the associated forme cylinder 49,50 a very high format variability is ensured.
  • the mutual adjustment of the cylinder and the imaging device takes place in the direction of imaging, i. in the direction of the optical axis of the imaging device.
  • high format variability only one guide element is required in each case, on which both the forme cylinder 49, 50 and the associated additional device are movable.
  • the printing unit cylinders are mounted on the fly. But you can also be stored at both ends in a carriage. Then, a second support wall is provided, which is provided analogously to the support wall 1 with guide elements and threaded spindles. This support wall can then be hinged to the sleeve or cylinder change or designed to be movable in the longitudinal direction of the cylinder, as described in the parallel application with the internal file number PB 04350.
  • the printing material web as indicated at 59 in FIG. 4, is guided approximately horizontally.
  • printing units according to the invention are conceivable by appropriately rotated arrangement of the guide elements by about 90 ° for a vertical run of the web 59.
