Definitions

  • the invention relates to a printing unit for a web-fed rotary printing press.
  • a printing unit which has two parallel to the end faces of the printing cylinder extending frame walls.
  • the printing cylinder can be equipped with sleeves of different diameters, so that the length of the printed image can be changed.
  • a carriage is provided on the frame walls on both sides of the printing cylinder.
  • the carriages are adjustable by means of working with pressure medium working cylinder. This construction has a relatively complicated structure.
  • the invention has for its object to improve a printing unit generic type with simple and inexpensive means so that despite a compact design long slide 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.
  • the walls 10, 15 are opposite parts of an opening 61 of the support wall 1. This opening 61 may for example be designed as an open slot.
  • On 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 formed 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 10 and the carriage 2 and 4 for the printing cylinder 6 and 8 are guided on the wall 15.
  • successive printing cylinder are thus arranged alternately on the opposite walls 10 and 15 respectively.
  • the threaded spindles 18 to 21 and the guide elements, e.g. 12, 13, 16, 17 are executed long.
  • the carriages 2 to 5 can better absorb forces and moments that occur during operation. Thanks to the arrangement of the guide elements 12, 13, 16, 17 on the walls 10, 15, a direct, vertical introduction of the supporting forces for the printing cylinder 6 to 9 in the support wall 1 in the longitudinal direction.
  • the support is therefore very stiff and low vibration, which is a prerequisite for a good print quality. It can be applied large forces.
  • the device is structurally simple and thus inexpensive to create.
  • the guide elements 12, 13, 16, 17 can be realized with standard linear guides.
  • the guide elements 12, 13 and 16, 17 may be performed on the wall 10 and 15 respectively as a continuous guide rails, while the carriages 3, 5 and 2, 4 are equipped with the counter rails.
  • 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.
  • a gear 22 to 25 is fixed on the one end of each threaded spindle 18 to 21 .
  • 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 conjunction, which on the Output shaft attached to the support wall 1 servomotor 34 is mounted 37.
  • the servomotors 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 sleeves on the two outer, designed as a cylinder form cylinder cylinders 6 and 9 can be changed, the printing cylinder 6 and 7 in Figure 1 so up and the printing cylinders 8 and 9 moved down so that all cylinders are lifted apart from each other, as indicated in Figure 1 with broken lines.
  • 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.
  • Figure 1 are further indicated schematically required for printing additional equipment. These are on the forme cylinder 6 an inking unit 62, a dampening unit 63 and an imaging device 64, as well on the forme cylinder 9, an inking unit 65, a dampening unit 66 and an imaging device 67, each with a traversing device 68 to 73 to the respective forme cylinder 6, 9 adjustable are. With the traversing devices, the changed positioning of the additional devices 62 to 67 also takes place on inserted form cylinders of other diameters and their other positions justified therefrom. Traversing devices are shown in DE patent application 100 08 215 A1. As an option, for example, extinguishing devices, blanket washing devices, ... may be provided. The form cylinder 6, 9 are also on the guides 12, 13 and 15, 16 for imaging in the region of the respective imaging device 64, 67 movable.
  • 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 which are designed as forme cylinders, outer printing unit cylinders 49, 50 and 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 Need to become.
  • 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 57, 58 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 is movable in its direction of movement. On the other hand, the arrangement is expediently 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 as far as 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 movable auxiliary or additional devices are assigned suitable drive means in the form of 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 application with the file number DE 199 37 796.0.
