Definitions

  • the ending relates to a wash bar for printing press cylinders according to the preamble of claim 1.
  • Such a wash bar is e.g. known from US-A-5 123 354.
  • the invention relates to a wash bar for Printing press cylinder, containing side parts and one with these connected traverse, a pressing element for pressing a Washcloth section of a washcloth to the outer surface of one cleaning cylinder, with the pressure element positioned on the crossbar is and extends in the longitudinal direction thereof, and bearings in the side parts for rotatable bearing of a clean cloth spindle and a dirty cloth spindle, around the washcloth from the clean cloth spindle over the pressure element to move the dirty cloth spindle the pressing element in Truss-transverse direction seen arcuate extends over an inner bar, the two Longitudinal edges of the pressing element between the inner bar and outer bars inserted are and the strips with the Traverse are connected.
  • the object of the invention is to solve a problem create through which the pressure element in a simple manner quickly can be assembled and disassembled.
  • the wash bar is characterized according to the invention in that that the longitudinal edges of the pressing element the crossbar sit on and each have a lateral edge projection that of the neighboring bar is overlapped, that the inner bar on the crossbar is releasably attached with fasteners that are outside of the Pressing element are accessible so that the inner bar can be detached from them and after loosening the inner bar from the pressing element in the longitudinal direction of the truss is extractable.
  • the pressure element preferably consists of a flexible elastic Material, e.g. As rubber or plastic, and is usually also called Pressure lip or pressure membrane called.
  • the press cylinder that washes with the wash bar can be, is in particular a so-called blanket cylinder in one Offset printing machine, however, can be any other cylinder or any different role of an offset printing press or another printing press his.
  • the washing bar 2 shown in the drawings for Printing press cylinder 4 contains a pressing element 6 for pressing one Wash cloth section 8 to the outer surface 10 of the cylinder to be cleaned 4.
  • the pressing element 6 is preferably a flexible lip made of rubber or Plastic. According to FIG. 1, it essentially has a cross section semicircular or u-shaped tunnel roof shape and forms between itself and one Inner bar 12 has a cavity 14.
  • the cavity 14 can be inflatable to Contact and press the pressure element 6 to the cylinder 4 with the washcloth section 8 lying between them
  • the embodiment shown in the drawings is not the cavity 14 inflatable.
  • Dashed lines 6-2 show how the pressing element 6 of the Cylinder 4 is deformable.
  • the wash bar 2 can be of a not shown Drive automatically from the basic position shown in Fig.
  • the longitudinal edges 16 and 17 of the pressing element 6 are between one Traverse 20, the inner bar 12 and outer holding bars 18 and 19 clamped, which each extend over the entire length of the Pressure element 6 extend and on the cross member 20 with screws 21 and 23 or are fastened by quick connection elements (clamping wedge or the like).
  • this inner bar 12 can the pressing element 6 are pulled out in the longitudinal direction of the bar. Then the pressing element 6 between the outer strips 18 and 19 in Strip longitudinal direction are pulled out or transversely to the outer strips 18th and 19 compressed and thus freed from them and then across or be taken out lengthways. The insertion of the pressing element 6 and the inner bar 12 between the outer bars 18 and 19 takes place in reverse order.
  • the longitudinal edges 16 and 17 of the pressing element 6 sit on the cross member 20 and each have an outwardly protruding edge projection 16-1 or 17-1, which is overlapped by the adjacent outer retaining strip 18 or 19.
  • the cross member 20 connects side parts 22 of the wash bar to one another.
  • bearings 24 for the rotatable mounting of a Clean cloth spindle 26, on which a clean wash cloth 28 is wound, and bearings 30 for a dirty cloth spindle 32 for winding each dirty washcloth section.
  • the dirty cloth spindle 32 is provided with a freewheel drive 34, which the dirty cloth spindle 32 then rotates and thereby the wash cloth from the cleaning cloth spindle 26 via a deflection plate 36 and the pressing element 6 transported by a predetermined washcloth section 8 when the Wash bar 2 from the basic position shown in Fig. 1 in the washing position is moved transversely to the cylinder 4. Press in the washing position not shown the pressing element 6 the washcloth section 8 against the lateral surface 10 of the cylinder 4 and is thereby easily deformed as this by the dashed lines 6-2 is shown.
  • the freewheel drive 34 is similar to one Ratchet trained.
  • the backward movement or free-running movement of the cloth driving lever 38 is limited by a sensor lever 40 which is provided with a roller 42, which rides on the wipe of the dirty cloth spindle 34 and thereby the return path in the freewheeling direction of the cloth driving lever 38 in Dependence on the respective diameter of the wipe certainly. This ensures that regardless of the winding diameter of the washcloth on the two spindles 32 and 26 each advance step of the Washcloth is about the same size.
  • the wash bar has two rollers 44 and 45 on each side, with which it moves in Guides a fixed bracket between the basic position and the Washing position is mobile.
  • a spray tube 50 is next to the path of movement of the washcloth 28 from the Clean cloth spindle 26 to the pressing element 6 arranged for moistening of the washcloth 28 by a curtain-like spray 52 from a very large variety of very small nozzle bores 54 in the spray tube 50.
  • the spray tube 50 is in a channel 56 of the upper outer holding strip in FIG. 1 19 used and is in it by the retaining bar against deflection supported.
  • the cross-sectional shape of the channel 56 is the round shape of the Spray tube 50 adapted and extends only partially, preferably around about 180 ° around the spray tube 50.
  • the spray tube 50 can radially in channel 56 may be used, however, is preferred Embodiment axially inserted into the channel 56 and from this too axially extractable.
  • the spray tube 50 is preferably only at its ends one fastener 58-1 and 58-2 releasably attached to the cross member 20.
  • the fasteners 58-1 and 58-2 are preferably mirror images or Identical liquid connector body, in which the ends of the Spray tube 50 are inserted liquid-tight.
  • the seal will preferably achieved by O-rings 60 which are on the pipe ends are attached.
  • the fluid connector bodies 58-1 and 58-2 are over Liquid lines 62-1 and 62-2 to a liquid source 64 connected. Liquid, e.g. Water, then in each case via the nozzle bores 54 of the spray tube 50 on the Wash cloth 28 sprayed during or just before the wash cloth 28 by one Step further to the pressing element 6 is moved.
  • the spray jet 52 is preferably in the inlet wedge between this washcloth 28 and the Pressure element 6 directed.
  • the spray tube 50 is preferably with a on its outer circumference Provide flat 66 against which a positioning screw 68 presses, which through the outer retaining strip 19, which carries the spray tube 50, is screwed through.
  • a positioning screw 68 presses, which through the outer retaining strip 19, which carries the spray tube 50, is screwed through.
  • One and / or the other of the two outer holding strips 18 and 19 can be a one-piece piece of material together with the traverse 20.
  • 5 and 6 show an embodiment in which both outer Holding strips 18 and 19 together with the cross member 20 a one-piece Are piece of material. 5 and 6 also show a possibility for detachable Attachment of the inner bar 12 to the cross member 20 by Quick fasteners 70 instead of screws 21.
  • the Quick fasteners 70 are about an axis of rotation 72 which in the Traverse 20 is mounted, pivotable on the inner bar 12.
  • the inner bar 12 can be designed such that it has the longitudinal edges 16, 17th of the, preferably compressibly elastic, pressing element 6 laterally engages and preferably against the cross member 20 and / or the outer Holding strips 18, 19 spans.
  • the inner bar 12 z. B. with Height distance above the crossbeam have 20 lateral edge projections, which overlap inner edge projections of the pressing element 6, or in Seen in cross-section have a dovetail shape or trapezoid shape, the width of the last near the traverse 20 is smallest and with increasing distance from the traverse becomes larger.
