Definitions

  • the invention relates to a printing machine with a plurality of inking unit, Plate, blanket and impression cylinder comprehensive printing units and a Turning device, wherein at least one impression cylinder as post-impression printing cylinder is arranged after the at least one turning device and carries an elevator or structural chrome surface.
  • a printing press of the type specified is known from DE 201 07 183 U1 known which is a printing press with a turning device arranged after-turn printing cylinder, which is an elevator a bendable substrate and one at the top of the Carrier material adherent fixed coating of molybdenum carries. Adhesive to the top of this coating is a sealant layer from the group of polyorganosiloxanes arranged.
  • the elevator has a facing the substrate surface profile of pointed cones with rounded profile domes.
  • the Coating also consist of tungsten carbide / cobalt.
  • One with one such post-press impression cylinder is used to in perfecting the deposition of paint or varnish from the first Side of the bow after turning to prevent.
  • From DE 199 31 305 A1 is a cleaning device for the printing unit a rotary printing machine, for example for a printing cylinder, known, as a cleaning system, a roller coated with a brush is provided.
  • the cleaning device disclosed in this document is used for cleaning printing cylinders without elevator or Structure chrome finish.
  • the invention has for its object to provide a printing machine, in which the Nachplanetary pressure cylinder leading a printing material gently getting cleaned.
  • the task continued to be the washing of the Post-print cylinder without manual post-cleaning and with minimal To carry out washing time.
  • the object is achieved in that the at least one Reverse pressure cylinder one of the blanket washing device of associated blanket cylinder separate Nachcht-Druckzylinderwasch issued having.
  • the solution according to the invention has the advantage that an effective cleaning with minimal washing times and manual post-cleaning is eliminated. Furthermore, for the blanket cylinder and the post-impression cylinder different washing media are used. About the separate after-turn printing cylinder washing device can also in Advantageously, the seal by applying a liquid Sealant be renewed.
  • a further advantageous development is also the impression cylinder without elevator or structural chrome surface with separate impression cylinder washing facilities to provide.
  • Such washing devices can Brush washing devices or preferably cloth washing devices be.
  • the washing time can be further minimized by advantageously also the inking units, the blanket cylinders or printing cylinders are assigned to be provided with separate washing facilities.
  • washing time is special large, if the said washing devices advantageously controlled so be that they work at the same time.
  • a particularly advantageous Embodiment of a printing press according to the invention is if the Wasch respondeds Kunststoffung in addition also the detergent and Power supply of the washing controls. A fully automatic Cleaning the entire printing press can thus be achieved.
  • the sheet-fed offset printing press shown in FIG. 1 has eight printing units 1 and two coating units 2 on.
  • the first four printing units 1 is followed by one Turning device 3, which from the feeder 4 through the four printing units. 1 transported sheet turns to a printing on the other side too enable.
  • Each printing unit 1 has an inking unit, not shown, and not illustrated dampening unit on. Furthermore, 1 belong to each printing unit Plate cylinder 5 and a blanket cylinder 6. Before the turning device 3 the impression cylinders 7 are arranged in each printing unit 1. The impression cylinder 7 may have a smooth chrome finish, but they do not wear one Elevator and no structural chrome surface. After the turning device 3 have the pressure cylinder associated with each printing unit 1 as so-called After-turn printing cylinder 8 a lift or a structural flow surface on.
  • a blanket washing device 10 is arranged, which is preferably designed as a cloth-washing device.
  • the Blanket washing device 10 can also be used as a brush washing device be executed.
  • the washing device 11 is as a brush or preferably formed as a cloth-washing device.
  • a cloth washing device has in a preferred embodiment a cleaning fluid supply for at least a first and a second Cleaning fluid.
  • the first cleaning fluid is preferably a detergent and the second cleaning fluid water.
  • a second cleaning fluid may alternatively a second detergent can be used.
  • the cloth washing device can also be designed such that the cloth washing device a cloth which, prior to insertion into the cloth-washing device is soaked in a cleaning fluid.
  • the after-turning device 3 arranged after-turn printing cylinder. 8 with elevator or structural flow surface have a post-turn impression cylinder washer 12 on, as a brush-washing device is trained.
  • the brush roller, not shown in Figure 1 of each brush-washing device has a roller core and a brush attachment.
  • the Brush trim has a plurality of individual bristles which are fixed at the end are arranged on the roll core.
  • To the surface of the reversion impression cylinder To spare even more, the bristles have at least partly at its free end a splitting into several bristle tips on, as in the DE patent application with the file number 20 2004 004 080.8 of 16 March 2004 is described.
  • the split bristle tips have a reduced bristle strength.
  • each printing unit 1 may, in a preferred embodiment one of the blanket washing device 10, the Impression cylinder washing device 11 or the after-conversion printing cylinder washing device 12 separate inking unit washing machine, which in Figure 1 is not shown, have.
  • the Printing machine according to the invention not shown in Figure 1 Washer control.
  • This washer control controls both the printing cylinder washing device 11, the post-impression printing cylinder washing device 12 as well as the Blanket cylinder washers 10 and the Inking unit washing devices.
  • In a particular preferred embodiment controls the Wasch Roads Kunststoffung in addition the detergent and Energy supply of all mentioned washing facilities.
  • a detergent can A3 detergents, high boilers, bio-detergents, UV-detergents or Detergent used for conventional and UV inks and hybrid inks become.
  • the Wasch Anlagens interviewedung set up so that a wash program is selectable from a plurality of washing programs, for example assigned to different degrees of contamination.
  • the after-turn impression cylinder washer 12 can be used to touch the surface of the after-turn printing cylinder with elevator a new sealing layer by means of a liquid Apply sealant.
