Definitions

  • the invention relates to a device for cleaning surfaces of printing cylinders by means of a cleaning cloth, which is transported from a supply roll on a AnprejSrau to a collecting shaft for dirty cleaning cloth, and with a Anstell annoying for advancing and retracting the AnpreJ31eiste with respect to the impression cylinder, for the feed a drive located behind the pressure bar is provided.
  • a device of this type is known from DE 297 07 975 Ul. Cylinders of printing presses, for example the blanket cylinder of offset printing presses are inevitably exposed to some contamination. This results from paint residues, dust, residues of operating materials, etc. It is therefore customary to clean pressure cylinders from time to time.
  • cleaning units that pull a cleaning cloth, possibly with the aid of cleaning agents, over the surface of the cylinder.
  • the cloth is dispensed from a supply roll and wound up on a collecting shaft for dirty cleaning cloth. Between the supply roll and the collecting shaft is a pressure bar which presses the cleaning cloth against the surface of the cylinder.
  • the pressure bar Since the pressure bar is needed only from time to time, it is usually advanceable and retractable by means of a suitable mechanism. To advance the pressure bar, it is known from the document mentioned above, to arrange an inflatable air hose along the AnpreJ31eiste behind this, which occupies an increasingly larger volume in the inflated state and advances the pressure bar. There are also other drives into consideration. Further details of construction does not contain the mentioned document. In particular, it is not said how the pressure bar should be withdrawn when it is not needed. Draining air from the hose will be necessary for this purpose, but may not be sufficient.
  • the invention has for its object to provide a device of the type mentioned above with a particularly compact Anprej31eiste with integrated return mechanism.
  • the device according to the invention is characterized in that the Anprej31eiste is guided displaceably within a substantially U-shaped beam profile in which at least one of the pressure bar in the return direction biasing spring is supported.
  • the Anpre_ßance together with the associated beam profile and the integrated return device thus forms a compact overall unit, which is usually accommodate even in confined spaces within a printing press.
  • the expandable hose used as an advantageous embodiment for the feed drive for the pressure bar also allows a particularly compact construction.
  • air pressure is suitable for expanding the hose, but it would also be possible to work with another gas or a hydraulic medium.
  • a compression spring within the U-shaped beam profile projections are preferably provided on the inner walls of this profile, which allow attacking the spring.
  • a number of apertures directed transversely to the applicator strip are preferably provided therein, into which are inserted supporting strips whose two outer ends are supported on projections on the inner wall surface of the beam profile.
  • the pressure bar preferably consists, as is known, of a core of metal with a working surface of rubber or an elastomeric plastic intended for the detection of the cleaning cloth.
  • Fig. 1 is a partial perspective view of a contact strip according to the invention with associated beam profile
  • FIG. 2 is a cross-section through the contact bar with the beam profile in the position of the control bar retracted from the printing cylinder;
  • Fig. 3 is a corresponding sectional view, but refers to the advanced position of the Anprej31eiste.
  • the circumference of a printing cylinder, for the cleaning of the pressure bar is provided, has been designated 14.
  • a continuous groove 16 At the bottom of the beam profile 12 there is a continuous groove 16 in which a hose 18 is located.
  • this hose can be widened by introducing a suitable medium, in particular by introducing compressed air.
  • the hose 18 exerts pressure on a lower bar 20 at the bottom of the pressure bar, which is designated 20.
  • the strip 20 has on its underside a groove 22 which extends over the length of the strip and the tube 18 receives.
  • the pressure bar 10 is made entirely of metal and has on the right side in Fig. 2 and 3 lying side, which faces the pressure cylinder 14, a rubber strip 24, which must be not only made of rubber in the true sense, but also suitable Plastics, especially elastomeric plastics, can be produced.
  • the rubber strip 24 is an extruded profile. It has, as the cross-section shown in Fig. 2 and 3 reveals, a C-shaped main part, which is shown in Figs. 2 and 3, however, in a reverse orientation. Within the C-shaped arc, support legs 26, 28, 30, 32 extend to the core 34 made of metal.
  • the C-shaped bend of the rubber strip 24 has extensions 36, 38 at both ends, which engage in corresponding grooves of the core 34 the pressure bar 10 can be inserted in the longitudinal direction.
  • the core 34 of the contact strip 10 has spaced, transverse to the longitudinal direction openings 40,42 in which support strips 44,46 lie.
  • the support strips 44,46 are in Fig. 1, 2 and 3 in a vertical orientation and thus parallel to the plane of the drawing.
  • the support strips 44,46 are based, as shown in FIGS. 2 and 3 can be seen in the interior of the beam profile 12 at protruding from the walls projections 48,50 from. These projections 48, 50 are designed as continuous strips on the inner walls of the beam profile 12.
  • the support strips 44,46 are based on the inside of the projections 48,50, as can be seen in Fig. 2 and 3.
  • the support strips 44,46 serve to support a helical compression spring 52, which is supported at its other end at the bottom of a bore 54 which is located in the bottom of AnspreJ31eiste 10 on the hose 18 side facing.
  • the support strips 44,46 emerge on both opposite sides from the cross-sectional area of the contact strip 10, this is done within groove-like recesses 56,58 which extend on both opposite sides of the AnpreJ31eiste 10 in the longitudinal direction.
  • the projections 48, 50 also lie on the inner wall surfaces of the beam profile 12. In this way, the pressure bar 10 can be displaced over a limited path within the beam profile 12 and in this way be turned on the pressure cylinder 14 and be withdrawn from this.
  • the support strips which are supported on the projection 48,50, in turn form an abutment for the helical compression springs 52, which endeavor to push back the Anpressance 10 from the advanced position.
  • the lateral flanks of the groove-like depressions 56, 58 in cooperation with the lateral flanks of the rib-shaped projections 48, 50 correspond to corresponding pairs of stops.
  • the positions of the threaded holes 60 correspond to the positions of the helical compression springs 52.
  • a threaded head is indicated, which is designated 62.
  • a shaft 64 extends coaxially to the left. This shaft 64 penetrates the support strips 44, 46, which are located in each case between the threaded head and the helical compression spring 52, in holes which are not designated.
  • On the screw compression springs facing side of the shaft 64 serves as a guide for the helical compression spring.
  • the outer diameter of the shaft 64 substantially corresponds to the inner diameter of the helical compression spring 52.
  • FIG. 2 shows the pressure bar in the retracted position or rest position.
  • the tube 18 is largely relaxed. Due to the action of the helical compression springs 52, which are supported on the support strips 44, 46, the part of the attachment strip facing the hose side is acted upon by the springs and the contact strip is moved to the left in FIGS. 2 and 3, ie in the rest position.
  • the hose 18 is inflated, that is to say filled with a pneumatic or hydraulic medium, it displaces the pressing bar to the right in FIGS. 2 and 3 until it rests against the pressure cylinder 14 while the helical compression spring 52 is compressed.
  • the shaft 64 also serves to guide the support strips 46,48, which could otherwise fall out of the openings 40,42. By the rotation of the threaded head 62, its axial position can be adjusted.
  • This position also affects the minimum distance between the support strip 46 (FIGS. 2 and 3) and the core 43 of the contact strip 10, as shown in FIG. This in turn has an influence on the action of the helical compression spring 52.
