  • the invention relates to a device for cleaning cylinders of a printing press according to the preamble of appended claim 1, with one to one to be cleaned cylinder adjustable, driven washing roller, with means for Applying washing liquids to the washing roller and / or to the to be cleaned Cylinder, as well as with a stripping device for the washing roller.
  • Cleaning devices of the type mentioned are used to eliminate Deposits and contaminants on cylinders of printing machines used, which result in particular from intensive contact with the printing materials.
  • the cylinders of the printing press are mainly stored Paper dust and ink.
  • Brush rollers are widely used as washing rollers because of their robustness achieve a long service life. It therefore happens that this is usually existing housing of a cleaning device according to the prior art only must therefore be opened because the squeegee is worn out and replaced got to.
  • the invention is therefore based on the object of a device of the type mentioned Art to improve in terms of their stripping.
  • the device according to the invention differs from the previously known devices So above all in that a squeegee is provided, which is jammed in a squeegee holder.
  • This clamping bracket has compared to the usual Screwing a squeegee has decisive advantages: by loosening the clamp and moving the squeegee in its holder can result in a worn squeegee easiest way can be adjusted so that they are not immediately replaced got to.
  • a clamp connection is also very easy to produce if the device was already in operation and is therefore in the area of the doctor blade Have accumulated dirt.
  • there is a clamping bracket the depth of attack of the squeegee is not fixed and can be adjusted as required.
  • a doctor blade the front and back of each, for example carries a squeegee edge, simply implemented in the clamping holder, that is, around her Longitudinal axis are rotated to the worn edge against the fresh edge replace.
  • a squeegee made from a profile element with a cross section that forming an equilateral hexagon can be done by simply turning the squeegee around 60 ° around its longitudinal axis a total of six renewal of the active one Experience squeegee edge.
  • doctor blade according to the invention is designed in this way and is arranged so that the active edge, which engages in the washing roller surface, is delimited by two surfaces which are in relation to the tangential plane of the Wash roller are symmetrical. This measure enables the Wipe off the dirt particles lifted off the cylinder with one and the same squeegee with constant effectiveness in both directions of rotation of the washing roller can be done.
  • doctor blade holder is preferably designed and aligned such that its projection onto the wash roller surface is as small as possible covers the tangential spraying away of the dirt particles scraped off the squeegee not hindered by the washing roller.
  • a bracket that fits one of his Edges arranged radially facing the washing roller forms the simplest design of such a squeegee holder.
  • the squeegee holder contains an adjusting element for the depth of attack of the squeegee, for example an adjusting screw, can be an adjustment or readjustment of the squeegee defined way and yet very simply by operating this adjustment element respectively.
  • an adjusting element for the depth of attack of the squeegee for example an adjusting screw
  • This holding profile can be in a simple manner as an extruded extruded profile, preferably Aluminum or an aluminum alloy can be manufactured. Profiles, i.e. support elements with a cross-section that remains unchanged over their entire length, can in the most diverse cross sections are manufactured, so that very simple connection points can be provided for the individual attachments and a modular Structure of the cleaning device is created.
  • extruded profiles are inexpensive to manufacture, offer a wide variety of possible cross-sections, are tough, stable and light. The low weight of an aluminum extrusion for example, facilitates the handling of an invention Device and thus increases their ease of installation.
  • Such a modular Structure of the device leads to considerable cost advantages in the production, since the individual components are kept ready-made and depending on the application can be installed.
  • a holding profile also offers the considerable advantage that it can be adapted to different cylinder widths by simply cutting to length can.
  • the easy interchangeability of the modular components increases the Ease of assembly and maintenance of the device.
  • the stripping device and, if appropriate the other attachments are attached to longitudinal grooves that run through the retaining profile, attachments with the help of suitable fasteners or brackets easy to use.
  • suitable fasteners or brackets easy to use.
  • undercut longitudinal grooves be provided and sliding blocks, clamping elements or threaded strips for Attachment of attachments can be used.
  • the attachments with their fasteners can also be connected so that neither a screw towards the washing roller a hole is still visible, since the respective attachment together with its Bracket or its fasteners on the end face in the associated longitudinal groove of the holding profile can be inserted. Screws or holes can then no longer be added by dirt particles.
  • an existing holding profile is used Washer roller with a concave outer contour adapted to the circumference of the washer roller Mistake.
  • the concave outer contour of the holding profile is also proportionate is brought close to the surface of the washing roller by a simple reversal of the direction of rotation of the washing roller is nevertheless formed Dirt accumulations on the holding profile can be removed by the washing roller itself:
  • the device according to the invention is self-cleaning.
  • a housing for the cleaning device according to the invention offers not to give up even if the housing is replaced by a holding profile is, it is advisable to in addition a splash guard and / or a on the holding profile Attach the drip pan.
  • the means for applying washing liquids through spray pipes and the Squeegee formed by a profile element can be constructed with a holding profile Device can be cut to any length, since they are not length-dependent Contains more parts.
  • the spray tubes can be attached to the holding profile particularly easily, if it fits into an outer surface of the spray tube, for the washing roller or recess open in the holding profile towards the cylinder to be cleaned.
  • the embodiment shown in Figure 1 is on a support profile 1, which is an aluminum extruded profile is built up.
  • the holding profile 1 carries on the one hand as a brush roller trained washing roller 2 and on the other hand a motor 3. Behind the Washer roller 2 is a gear housing 4 can be seen, the rear, not here visible end face of the holding profile 1 is attached and the motor 3 to the shaft 5 the washing roller 2 couples.
  • cavities 6, which the material requirements for Reduce extruded support profile 1 are two continuous cylindrical longitudinal channels 7 for the production of front-side screw connections.
  • a splash guard 8 is attached to the device, with a sliding block 9, which is inserted into a first undercut longitudinal groove 10 and one of externally accessible screw 11 receives.
  • a second undercut longitudinal groove 12 is used to attach a motor bracket 13, which is also a thermal bridge between the motor 3 and the holding profile 1.
  • a third longitudinal groove 14 sits with sliding blocks 15 attached to a number of squeegee holders 16 which are clamping hold a doctor blade 17 designed as a profile with a hexagonal cross section.
  • the bracket the doctor blade 17 can be released in each case on a clamping screw 18; the depth of attack the doctor blade 17 to the washing roller 2 is designed with an adjusting screw Adjustment element 19 adjustable.
  • On the bottom is a sump 20 for Collect the dirt particles scraped off the doctor blade 17 on the holding profile 1 attached.
  • a first spray tube 21 and a second spray tube 22 for spraying Washing liquids on the washing roller 2 are in a correspondingly shaped recess 23 of the holding profile 1 used.
