  • cylinders in particular blanket cylinder, impression cylinder, plate and Shaping cylinders, cooling rollers, guide rollers, ink rollers and dampening rollers.
  • Machining and for driving the substrate sheets or substrate webs is an intensive contact between the substrates and the cylinders necessary. This creates deposits of paper dust on the cylinders and printing ink.
  • the deposition rate is due to the high viscosity and Adhesion of the ink particularly high.
  • Printing machines are, in addition to the still encountered washing of Hand, automated cleaning equipment used:
  • a cleaning device which is connected to a is to be cleaned cylinder of a printing unit and a driven Washing roller comprises, whose axis of rotation parallel to the axis of rotation of a cleaning cylinder is and whose peripheral surface has an angular range, which is intended for contact with the cylinder.
  • the washing roller is sprayed over a detergent feed with cleaning agents.
  • For stripping the lifted off the cylinder impurities is a Squeegee provided.
  • Such a cleaning device can also be taken from EP 0 659 560 B1.
  • the known automated cleaning devices for cylinders of printing presses are usually assigned to a cylinder permanently, where they for the cleaning process can be made to this.
  • the rotating one Washing roller is moistened with cleaning liquids, so that the am Cylinder adhering impurities are softened and lifted.
  • the dirt picked up by the washing roller is released by the wiper continuously eliminated.
  • the invention is therefore based on the object, a device for cleaning of cylinders of a printing press according to the preamble of claim 1 to improve so that the necessary installation space for this device considerably is reduced.
  • the device according to the invention comprises a washing roller whose peripheral surface has two separate angular ranges, each for the contact with one of the two cylinders to be cleaned is provided. hereby It is possible, the washing roller substantially in the gap between the insert both cylinders to be cleaned and both cylinders with and same washer to clean, without a cantilever lever assembly for attach a pivoting movement or a rotational movement of the cleaning device to have to.
  • the two cylinders are cleaned to be alternately cleaned by a very small pivoting movement of the washing roller; but preferably the washing roller can also be used for the cleaning process be made to the cylinder that they simultaneously with both cylinders comes into contact and simultaneously cleans both cylinders. It lies on the Hand, that in particular the latter alternative a particularly fast cleaning the cylinder allows.
  • the according to the invention for the adjusting movement and / or the pendulum movement can be accommodated in a small space be so that the inventive device is almost completely in can insert the gap between two adjacent cylinders and the space remains free from these cylinders.
  • Such a finger guard is preferably so on attached to the device according to the invention that it is the adjusting movement and / or the pendulum movement of the washing roller does not join, but essentially remains stationary.
  • the device according to the invention for Cleaning each of two superimposed blanket cylinder one H-printing unit of an offset printing machine. It is favorable if, for Drive the washing roller a motor of low height is provided, which in Direction to the printing substrate even before the washing roller in the gap between the is arranged to be cleaned blanket cylinders.
  • the installation space required for the device according to the invention becomes particularly small however, if provided for driving the washing roller, a motor is, which is arranged coaxially with the washing roller.
  • the Washing roller is designed as a brush roller.
  • brush rollers achieved by the applicant in automated cleaning devices according to the prior art For some time very good cleaning results.
  • each separately cleaning fluids be supplied.
  • cleaning liquids for example, oils, organic solvents, but also to understand water and cleaning emulsions.
  • a housing in which the washing roller is arranged and which ever has a separate opening for the first and having the second angular range of the peripheral surface of the washing roller.
  • these two openings are on two opposite sides of the Housing be arranged.
  • the motor for driving the washing roller can thus be connected to the washing roller be that the drivetrain between the engine and the housing or frame a detachable element, for example a releasable gear connection, contains.
  • the motor can be arranged stationary in the printing press be with the washer housing or frame by separating the Drive train is nevertheless easy to remove and install.
  • Figure 1 which is a device according to the invention in a schematic Sectional view shows a first cylinder 1 and a second cylinder 2 are indicated, which are arranged closely adjacent to each other. In between is located in a housing 3, a washing roller 4, which of a motor. 5 is driven by an unillustrated gear or a belt. instead a housing 3 may also be provided only a frame. alternative to the illustrated arrangement of the motor 5, this can also outside the Housing 3 to be firmly mounted on the printing press; the motor 5 then carries, for example a gear, which in a connected to the washing roller 4 Gear engages, but in an expansion of the housing 3 from this engagement solves.
  • a gear which in a connected to the washing roller 4 Gear engages, but in an expansion of the housing 3 from this engagement solves.
  • An attached to increase the safety finger guard plate 11 sets down in a sump 12 for the released from the cylinders 1 and 2 and on the Abstreifeinrichung 10 thrown off from the washing roller 4 Dirt away.
  • the washing roller 4 is arranged so that its axis of rotation parallel to the axes of rotation the cylinder 1 and 2 is. Pointing below its axis of rotation the peripheral surface 13 of the washing roller 4 has a first angular range ⁇ , in which it protrudes through an opening of the housing 3.
  • a (not shown) Mechanics can the housing 3 with the washing roller 4 so to the first Cylinder 1 are employed, that the peripheral surface 13 of the washing roller 4 in the first Angular range ⁇ contact with the first cylinder 1 receives and cleans this.
  • the device can be moved by a small linear movement of the housing 3 left, which is not taken part of the finger guard 11, at the same time the first cylinder 1 and the second cylinder 2 are employed, whereby a simultaneous cleaning of the two cylinders 1 and 2 takes place:
  • the washing roller. 4 rotates preferably during the cleaning process in a clockwise direction, so that first in the first angular range ⁇ deposits and impurities to be detached and lifted off at the first cylinder 1. After that, in the second Angular range ⁇ the second cylinder 2 cleaned. This will wet the spray pipes 6 and 7, the washing roller 4 with cleaning liquids 8 and 9, for example with water and a hydrocarbon.
  • the in FIG 1 housing 3 perform a slight pendulum motion, so that the peripheral surface 13 of the washing roller 4 alternately in contact with the first Cylinder 1 or the second cylinder 2 comes. This leaves the finger guard 11 with the drip pan 12 also stationary.
