Definitions

  • the invention relates to a washing device for a cylinder in a printing press with a washing cloth and an ultrasonic source, which directs sound energy to the cylinder surface.
  • Such a washing device is for example from the WO 03/011599 known.
  • There is an ultrasonic source is provided to assist the washing process, which is to facilitate the removal of impurities, color, etc. from the surface of the clamped on a transfer cylinder blanket in an offset printing machine.
  • a cloth washing device for a digital printing machine described.
  • a liquid-impregnated cleaning tape on the cylinder surface can be acted upon with an ultrasonic actuator to clean the printing image bearing cylinder.
  • a washing device for the blanket cylinder of an offset printing machine which has an ultrasonic generator, but no washing cloth.
  • the dissolved dirt particles are to be scraped off by rubber lips from the cylinder surface.
  • JP 11-70641 describes the use of an ultrasonically vibrating washing doctor blade which is in direct mechanical contact with the rubber surface.
  • devices of this type there is a risk that the sprayed liquid sprayed on the blanket in front of the doctor blade into the printing machine and there causes damage due to corrosion, etc.
  • the sound energy emitted by one or more ultrasound transmitters of an ultrasound source is concentrated on a substantially line-shaped focal region extending parallel to the cylinder axis on the cylinder surface.
  • an ultrasonic cylinder lens is advantageously used, which consists of a single or more cylindrical or toric acoustic lenses.
  • the focusing device can also be formed by a cylindrical concave shape of the sonotrodes or ultrasonic vibrator, of course, both measures, the cylindrical sound lens and the concave shape of the sonotrodes can be combined.
  • the high sound energy density generated on the cylinder or blanket surface in the substantially linear focus region then dissolves the paint or impurities from the surface, whereby the dirt or color particles are carried away by the moist washing cloth applied to the surface. It may be particularly advantageous if the washcloth continuously moves over the line-shaped focus area during the washing operation, while at the same time the cylinder is rotating at a greater surface speed in the direction of the wash cloth movement.
  • the cylindrical sound lens which generates the linear focus either alone or with other tools together, to press the wash cloth against the cylinder surface to be cleaned.
  • the construction becomes particularly simple when this cylindrical lens is designed as a tubular plastic part, in the interior of which the washing liquid for moistening the washing cloth or the cooling liquid for cooling the ultrasonic generator is contained.
  • two or more functions namely the guiding of the washing liquid or cooling liquid, the focusing of the ultrasonic energy and the pressing of the washing cloth to the rubber or cylinder surface are fulfilled by a component.
  • FIG. 9 is a schematic representation of the cylinder in the printing unit of an offset printing press in the plane perpendicular to the cylinder axes.
  • PZ is like that referred plate cylinder referred to the holders on the clamping channel which is not shown rolls of an inking unit colored printing plate is attached.
  • the print image on the printing plate is transferred to the rubber blanket GT when the cylinders are rotated, which is mounted on the blanket cylinder GTZ shown below.
  • PB of the paper sheet is called, which is passed between the blanket cylinder GTZ and the impression cylinder GDZ while the blanket GT is printed with color.
  • a blanket washing device GTW For washing the blanket, as usual in offset printing machines, a blanket washing device GTW is provided, which can be employed along the arrow P during order change after the end of the printing operation on the blanket cylinder GTZ.
  • This washing device GTW usually contains a washing cloth 10, which is cyclically cycled from a supply roll 11a unwound and wound onto a second roll 11b. In between, the washing cloth 10 is pressed by a pressing element 11 against the surface of the rubber blanket GT to be cleaned.
  • blanket washing devices work so that the cylinder surface to be cleaned rotates past the pressed-on wash cloth and this is repeatedly indexed several times during one revolution in order to convey the colored strip-shaped region of the washing cloth again and again in the direction of the take-up roll 11b.
  • the washing device further includes a drive for the movement of the washing cloth and a device for the supply of washing liquid, unless already the supply roll 11 a is soaked with washing liquid.
  • FIG. 1 shows in more detail a first embodiment of the invention modified according to the pressing element 11 of the blanket washing device GTW in section perpendicular to the cylinder axes.
  • FIG. 1 consists of the pressing member 11 of a U-shaped aluminum profile, which on the side with which the wash cloth 10 against the Blanket GT pushes, is provided with a longitudinal slot.
  • an elongated sonotrode with the in FIG. 1a shown construction. It consists of two strip-shaped masses 13a and 13b, between which a piezo-ceramic layer 13c is arranged, which is vapor-deposited on both sides with metal electrons.
  • the lower, the wash cloth 10 facing part 13b of the sonotrode 13 is concave on its underside 14 and focuses the radiated ultrasonic power to a narrow, substantially linear focus area on the surface of the blanket GT.
  • the sonotrode 13 is pressed by springs 16 against a provided with a seal 18 seat on the inner sides of the two legs of the U-shaped profile 12.
  • a seal 18 seat on the inner sides of the two legs of the U-shaped profile 12.
  • strips 12a are used in the profile 12 for positional fixation.
  • the rounded two U-shaped legs of the profile 12 press the wash cloth 10 against the surface of the blanket GT.
  • inflow tubes 15 are provided along the profile 12, which open into channels 17, through which the washing liquid enters the space between the washing cloth 10 and the concave surface 14 of the sonotrode 13 and fills it. Due to the washing liquid, the ultrasound energy is effectively brought to the surface of the blanket GT while avoiding excessive reflections, where it can dissolve dirt and paint residues adhering to the blanket surface due to the onset of cavitation of gas bubbles formed in the liquid in the focus area.
  • FIG. 2 shows an alternative second embodiment of the modified according to the invention pressing member 11 of the blanket washing device GTW.
  • FIG. 2 In the embodiment according to FIG. 2 are compared to FIG. 1 identical or similar parts with a reference number higher by 10 to facilitate understanding.

  • the membrane 26 limits the flow of wash fluid from the inflow tubes 25 into the washcloth 10 and ensures that no wash liquid exits when the wash is complete and the pressure in the inflow tube 25 is turned off.
  • the cylindrical plastic lens 29 is made of Plexiglas. Because in this material the speed of sound is almost twice as high as in water, the plano-concave cylindrical lens acts collecting and concentrates the ultrasonic power in a very narrow line-shaped area, as indicated by the arrows.
  • the length of the pressure element of the blanket washing device can be adapted to different format widths, without the need to manufacture special individual sonotrodes for the format in each case.
  • a number of individual toric or cylindrical individual lenses may be provided instead of the cylindrical lens made of plastic, which are each associated with the individual sonotrodes.
  • a toric formation of the individual lenses supports the uniformity of the sound propagation along the cylinder surface over the regions which are switched off by the webs.
  • FIG. 3 shows a third embodiment of the modified according to the invention pressing member 11 of the blanket washing device GTW.
  • the cuboid sonotrodes are replaced by ultrasonic transducers 33a, 33b Vietnamese cross-section.
  • ultrasonic transducers 33a, 33b ... can be purchased inexpensively as purchased parts, because they are used in large quantities in other applications.
  • the ultrasound transmitters 33a, 33b ... are not arranged in a line one behind the other, but are staggered close to one another and are alternately arranged inclined relative to one another, as in FIG FIG. 3a is clarified.
