Definitions

  • the invention relates to a cleaning device for cylinders of printing presses, preferably offset printing presses, which is equipped with a wash roller which can be turned on and off a cylinder and can be sprayed with a liquid and, if necessary, can be lifted off the cylinder jacket surface in the area of the gripper bridge of a printing cylinder.
  • Such a cleaning device is e.g. known from DE-OS 1 436 535, wherein this device cannot be lifted off in the region of the gripper bridge of the cylinder jacket surface.
  • a detachable washing device is known for example from EP 004 605 A1 and DE 3 614 496 A1.
  • a disadvantage of these known cleaning devices with a washing roller is that the washing rollers are each arranged in a housing and the housing has an opening facing the cylinder jacket surface. The cleaning process of the washing roller itself takes place during the cleaning of the cylinder surface with the washing roller in the turned position. Since the housing of the washing roller is open, the washing roller can dry out more quickly when it is in the parked position (rest position), which reduces the service life. Furthermore, when the position is switched off, cleaning agents or their evaporation can escape into the environment through the opening, which impairs the emission values in the pressroom.
  • the cleaning device essentially has a housing that extends beyond the entire width of the cylinder to be cleaned.
  • the housing has an opening facing the cylinder and accommodates at least one rotatably mounted washing roller and additionally has a movable housing part, which opens this opening for placing the washing roller on the cylinder or closes after the washing process has ended, with the washing roller turned off.
  • This has the advantage that the washing roller can be cleaned in the closed housing during the printing operation in addition to the washing process known per se on the cylinder jacket surface. Emission values in the pressroom are reduced because less cleaning agent escapes into the environment. Rapid soiling of the washing roller is prevented and the service life of the cleaning device in the printing press is increased.
  • the cleaning time is further shortened, since the cleaning process always starts with an already cleaned washing roller.
  • the housing can also accommodate several wash rollers that can be adjusted to the cylinder.
  • the opening of the housing can also be opened or closed with a plurality of movable housing parts.
  • a washing cloth can also be arranged in the housing instead of a washing roller.
  • the sprayable washcloth is received in the housing of the cleaning device with a supply roller, a take-up roller and a pressure element or a roller for the washcloth.
  • the movable housing part In the parking position (rest position), the movable housing part has closed the opening in the housing.
  • the washcloth dries out more slowly, the consumption of cleaning agents can be reduced and the service life is increased.
  • the escape of cleaning agents from the washcloth is minimized, which also reduces emissions in the pressroom.
  • the mode of action is as follows:
  • the cleaning device is normally in the parked position (FIG. 1).
  • the washing roller 4 has no contact with the cylinder 1 and the opening 9 in the housing 2 is closed by the movable housing part 3.
  • the washing roller 4 is in the parked position in the rest position when the roller 4 has no contamination. If the roller 4 is contaminated by previous cleaning operations on the cylinder 1, the washing roller 4 is set in rotation via the drive (not shown) and liquids are sprayed individually or jointly onto the surface of the washing roller 4 via the water supply 6 and cleaning agent supply 7 as required .
  • the degree of soiling of the washing roller 4 can be determined empirically or preferably by a mechanical or electrical sensor which is assigned to the washing roller 4.
  • the washing roller 4 is in contact with the doctor blade 5 arranged on the housing in such a way that the impurities picked up by the outer surface of the cylinder 1 are sprayed off toward the bottom of the housing and flow out of the housing 2 with the liquids via the outlet 8.
  • the drive is stopped and the roller 4 is in the rest position when the opening 9 is closed and in the parked position.
  • the washing roller 4 In the employed position (FIG. 2), the washing roller 4 is in contact with the outer surface of the cylinder 1.
  • the Cleaning device according to the invention on the cylinder 1 not shown cylinder 1.
  • the housing part 3 is moved in such a way that the opening 9 is opened and the washing roller 4 comes into contact with the lateral surface of the cylinder 1 (starting position).
  • the washing roller 4 is set in rotation beforehand, the direction of rotation of the washing roller 4 being opposite to the direction of rotation of the cylinder 1.
  • the washing roller 4 is sprayed with water and / or cleaning agent via the feeds 6, 7.
  • the washing roller 4 with the housing 2 is temporarily switched off via the working cylinder, so that the grippers move past the washing roller 4 without contact.
  • the opening 9 of the housing 2 remains free, for example by the movable housing part 3 remaining in a lock.
  • the washing roller 4 with the housing 2 is placed on the cylinder 1 again.
  • the washing roller 4 with the housing 2 is shut off from the cylinder 1 and the housing part 3 closes the opening 9.
  • the washing roller 4 is washed in the now closed housing 2 during printing or remains in the rest position until the next cleaning operation .
