Definitions
- the invention relates to a washing bar for printing press cylinders according to the preamble of claim 1.
- the invention relates to a washing bar for printing press cylinders, comprising side parts and a crossbar connected to them, a pressing element for pressing a washing cloth section of a washing cloth onto the lateral surface of a cylinder to be cleaned, the pressing element being positioned on the crossbar and extending in the longitudinal direction thereof, bearings in the side parts for the rotatable mounting of a clean cloth spindle and a dirty cloth spindle, in order to move the wash cloth from the clean cloth spindle over the pressing element onto the dirty cloth spindle.
- the object of the invention is to provide a possibility by which the pressing element can be quickly assembled and disassembled in a simple manner.
- the washing bar is characterized according to the invention in that the pressing element extends in the transverse direction of the crossbar in an arcuate manner over an inner bar, that the two longitudinal edges of the pressing element are inserted between the inner bar and outer bars, that the bars are connected to the crossbar, that the longitudinal edges of the pressure element sit on the cross member and each have a lateral edge projection which is overlapped by the adjacent bar, that the inner bar is releasably attached to the cross member with fasteners that are accessible from outside the pressure element, so that the inner bar is releasable and after loosening, the inner bar can be pulled out of the pressing element in the longitudinal direction of the truss.
- the pressing element is preferably made of a flexible material, e.g. As rubber or plastic, and is usually referred to as a pressure lip or pressure membrane.
- the printing press cylinder which can be washed with the washing bar, is in particular a so-called blanket cylinder in an offset printing press, but can also be any other cylinder or roll of an offset printing press or another printing press.
- Fig. 1 shows schematically a side view of a wash bar after the
- FIG. 2 shows a longitudinal view of a spray tube from FIG. 1 with the elements holding it, essentially in the plane II-II from FIG. 1 in the direction of the arrows there,
- Fig. 3 is a cross-sectional view along the plane III-III of Fig. 2 in
- Fig. 4 out of scale a front view of essential parts of the
- Fig. 5 is an unscaled side view of another
- Embodiment of a holding device according to the invention by means of which a washcloth pressing element and a spray tube can be exchanged quickly,
- the washing bar 2 for printing press cylinder 4 shown in the drawings contains a pressing element 6 for pressing a washing cloth section 8 against the lateral surface 10 of the cylinder 4 to be cleaned.
- the pressing element 6 is preferably a flexible lip made of rubber or plastic. 1 has a substantially semicircular or U-shaped tunnel roof shape in cross section and forms a cavity 14 between itself and an inner strip 12.
- the cavity 14 can be inflatable for contacting and pressing the pressing element 6 against the cylinder 4 the washcloth section 8 between them. According to the embodiment shown in the drawings, the cavity 14 is not inflatable.
- Dashed lines 6-2 show how the pressing element 6 can be deformed by the cylinder 4.
- the washing bar 2 can be automatically advanced by a drive, not shown, from the basic position shown in FIG.
- the longitudinal edges 16 and 17 of the pressure element 6 are clamped between a cross member 20, the inner bar 12 and outer retaining bars 18 and 19, which each extend over the entire length of the pressure element 6 and on the cross member 20 with screws 21 and 23 or by quick connection elements ( Wedge or the like.) Are attached.
- this inner bar 12 can be pulled out of the pressing element 6 in the longitudinal direction of the bar.
- the pressing element 6 between the outer strips 18 and 19 can be pulled out in the longitudinal direction of the strip or compressed transversely to the outer strips 18 and 19 and thus freed from them and then removed transversely or lengthwise.
- the insertion of the pressing element 6 and the inner bar 12 between the outer bars 18 and 19 takes place in the 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 up the respectively dirty wash cloth section.
- the dirty cloth spindle 32 is provided with a freewheel drive 34, which then rotates the dirty cloth spindle 32 and thereby transports the washing cloth from the cleaning cloth spindle 26 via a deflection plate 36 and the pressing element 6 by a predetermined washing cloth section 8 when the washing beam 2 is of the type shown in FIG. 1 basic position shown is moved into the washing position across the cylinder 4. In the washing position, not shown, the pressing element 6 presses the washing cloth section 8 against the lateral surface 10 of the cylinder 4 and is thereby slightly deformed, as is shown by the dashed lines 6-2.
- the freewheel drive 34 is similar to one Ratchet trained.
- the backward movement or freewheeling 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 wash cloth roll of the dirty cloth spindle 34 and thereby determines the return path in the free running direction of the cloth driving lever 38 depending on the respective diameter of the dirty cloth roll , This ensures that regardless of the winding diameters of the washcloth on the two spindles 32 and 26, each feed step of the washcloth is approximately the same size.
- the washing bar has two rollers 44 and 45 on each side, with which it can be moved in guides of a fixed holder between the basic position and the washing position.
- a spray tube 50 is arranged next to the movement path of the wash cloth 28 from the cleaning cloth spindle 26 to the pressing element 6 for moistening the wash cloth 28 by a curtain-like spray jet 52 from a very large number of very small nozzle bores 54 in the spray pipe 50.
- the spray tube 50 is inserted in a channel 56 of the upper outer holding strip 19 in FIG. 1 and is held therein by the holding strip against deflection supported.
- the cross-sectional shape of the channel 56 is adapted to the round shape of the spray tube 50 and extends only partially, preferably by approximately 180 °, around the spray tube 50.
- the spray tube 50 can be inserted radially into the channel 56, however, according to the preferred embodiment, it is pushed axially into the channel 56 and can also be axially pulled out of this.
- the spray tube 50 is preferably releasably attached to the crossmember 20 only at its ends by means of fastening means 58-1 and 58-2.
- the fastening means 58-1 and 58-2 are preferably a mirror-image or identical liquid connection body, into which the ends of the spray tube 50 are inserted in a liquid-tight manner.
- the seal is preferably achieved by O-rings 60 which are attached to the pipe ends.
- the fluid connection bodies 58-1 and 58-2 are connected to a fluid source 64 via fluid lines 62-1 and 62-2. Liquid, e.g. Water, then sprayed onto the washcloth 28 via the nozzle bores 54 of the spray tube 50, during or shortly before the washcloth 28 is moved one step further to the pressing element 6.
- the spray jet 52 is preferably directed into the inlet wedge between this wash cloth 28 and the pressing element 6.
- liquid connection bodies 58-1 or 58-2 To remove the spray tube 50, only one of the two liquid connection bodies 58-1 or 58-2 needs to be unscrewed from the cross member 20. Then the spray tube 6 can be pulled axially out of the other liquid connection body 58-1 or 58-2 and out of the channel 56 of the holding strip 19. This means very little assembly effort.
- the liquid connector body 58-1 or 58-2 to be removed from one pipe end can also be arranged on the traverse 20 so as to be longitudinally displaceable.
- the liquid connection bodies 58-1 and 58-2 could be releasably attached to the outer holding strip 19 which carries the spray tube 50 instead of to the cross member 20.
- the spray tube 50 is preferably provided on its outer circumference with a flat 66 against which a positioning screw 68 presses, which is screwed through the outer retaining strip 19 which carries the spray tube 50. This defines the angle of rotation position of the spray nozzle openings 54 relative to the retaining strip 19. This positioning screw 68 must be unscrewed in each case if the spray tube 50 is not pulled radially but axially or inserted from or into the channel 56 of the outer retaining strip 19.
- One and / or the other of the two outer retaining strips 18 and 19 can be a one-piece piece of material together with the cross member 20.
- 5 and 6 show an embodiment in which both outer retaining strips 18 and 19 together with the cross member 20 are a one-piece piece of material.
- FIGS. 5 and 6 show a possibility for the detachable fastening of the inner bar 12 to the cross member 20 by means of quick fastening elements 70 instead of screws 21.
- the quick fastening elements 70 can be pivoted onto the inner bar 12 about an axis of rotation 72 which is mounted in the cross member 20 ,
- the inner bar 12 can be designed such that it laterally overlaps the longitudinal edges 16, 17 of the, preferably compressibly elastic, pressing element 6 and preferably clamps against the crossmember 20 and / or the outer holding bars 18, 19.
- the inner bar 12 z. B. with height spacing above the cross member 20 have lateral edge projections which overlap the inner edge projections of the pressing element 6, or have a dovetail shape or trapezoidal shape in cross section, the strip width near the cross member 20 being the smallest and increasing with increasing distance from the cross member.
