Definitions

  • the invention relates to a device for cleaning the Shell surface of a cylinder of a printing press with a a housing facing the cylinder to accommodate a cylinder that can be brought into contact with rotatable cleaning element, a feeder for a Cleaning fluid and a supply for water and with a drain for draining dirty cleaning fluid.
  • the supplies for cleaning fluid are of the specified type and water from two arranged in the housing Spray pipes that span the width of the cleaning device extend and several along the length in Have spaced openings arranged on the Cleaning element are directed.
  • the spray pipes are included a feed line, via which with the aid of a Pressure fluid supplied the cleaning fluid or water becomes.
  • the cleaning device has one in the housing rotatable wash roller, the shaft with a own drive is coupled. With the washing roller is one Squeegee constantly engaged, attached to the case is.
  • a cleaning device from DE 298 19 374 U1 for cleaning the outer surface of a cylinder in a printing press known in which in a housing with a wash roller rotatably mounted therein two preferably supply systems for supply formed by spray pipes a cleaning fluid are arranged. At least one Feed system is rotatably mounted on the housing and coupled with an actuator through which the Feed system is rotatable in different positions. By Rotating the feed system can cause that emerging from openings Cleaning fluid directed onto the washing roller or from the Wash roller can be averted. Furthermore, a Feed system in contact with the surface of the washing roller to serve as a wiping element.
  • the used in cleaning devices of the specified type Cleaning fluid has the job to remove paint residues and To loosen dirt on the surface of the surface to be cleaned Cylinders stick.
  • the cleaning fluid is therefore in its Composition on each used for printing Color system matched.
  • the different cleaning fluids are often incompatible with each other and are therefore not allowed be mixed together.
  • For printing operation follows from this that when changing the color system also that of Cleaning fluid supplied to cleaning device changed must be what with an additional changeover and the loss of detergent content of the feed lines is.
  • the invention has for its object a cleaning device to create the type mentioned at the beginning changing the color system does not require any special conversion work requires and avoids loss of cleaning fluid.
  • the object is achieved in that at least two separate feeds for cleaning fluid are provided. With each feed over its own delivery line with its own storage container connected is.
  • the cleaning device according to the invention enables Use of different cleaning fluids without special Conversion measures.
  • the color can be exchanged for a different color system Container for cleaning fluid and changing the line content in the supply lines of the cleaning device omitted.
  • This is linked to the savings of Detergent and changeover time, the risk of accidental Mixing incompatible detergents in the Pipe system and possibly resulting malfunctions are avoided, operational safety is increased.
  • the cleaning device shown in Figure 1 is on one Cylinder 1, for example a blanket cylinder, forme cylinder or printing cylinder of a printing machine.
  • the cleaning device has a housing 2 of approximately rectangular cross-section that extends across the entire Width of the cylinder 1 extends.
  • the housing 2 consists of an upper housing part 3 and a detachably attached thereto Lower housing part 4. Located on lower housing part 4 a drain 5.
  • the housing 2 has one of the to be cleaned Lateral surface of the cylinder 1 facing opening 6, through which a rotatably mounted in the housing 2 Washer roller 7 protrudes so far that it can be seen in FIG shown position of the cleaning device with the Cylinder 1 is in contact.
  • the washing roller 7 is through a Drive can be driven in the direction of the arrow.
  • a first spray pipe 8 for supplying a first cleaning fluid
  • a second spray tube 9 for feeding a second cleaning fluid
  • a third spray tube 10 for Supply of water.
  • the spray tubes have a variety smaller orifices or nozzles that appear in regular Distances from each other over the entire length of the spray tubes are distributed.
  • the spray tubes 8, 9 are the upper area the washing roller 7 adjacent and are in one Distance from this.
  • the spray tube 10 is the contact point the washing roller 7 with the cylinder 1 opposite and engages in the outer contour of the bristles Wash roller 7 a. As a result, the spray pipe 10 additionally the function of a scraper.
  • Spray tubes 8, 9, 10 are rotatable about their longitudinal axis on the Housing 2 stored and with outside the cleaning device arranged actuators coupled. This can the spray tubes 8, 9, 10 in different working positions be rotated, as detailed in DE 298 19 374 U1 is described.
  • the valve block 14 is in three through the machine controller Switchable positions. In every position there is a different one Feed lines 11, 12, 13 with the pump assigned to them 18, 19, 20 and the storage container 15, 16 assigned to them 17 connected. In the middle position shown in the drawing the valve block 14 is the connection of the Reservoir 16 to the spray tube 9 open and the connection from the storage containers 15, 17 to the spray pipes 8, 10 blocked. It is therefore only possible to use the for example cleaning fluid intended for offset ink supplied to the spray device via the spray tube 9 become. Should a different cleaning fluid from the reservoir 15 or water from the reservoir 17 are supplied, a corresponding actuation of the Valve blocks 14 required by the machine control. Instead of the valve block 14 can of course also other valve controls, for example three individual, directional valves that can be switched independently of one another are provided his. These can be controlled in such a way that at the same time the corresponding from two or three spray tubes Media can be fed.
