Definitions

  • the invention relates to a cleaning device for printing press cylinders with at least one cleaning element accommodated in a housing, the housing having an opening towards the cylinder surface.
  • the invention is particularly suitable for cleaning blanket cylinders, impression cylinders and plate cylinders or forme cylinders.
  • DE 2 159 115 B2 discloses a device of this type for cleaning a printing press cylinder.
  • the cleaning device has a housing with an opening adjacent to the cylinder jacket.
  • a brush roller serves as a cleaning element, to which a cleaning fluid is supplied.
  • the housing has a return line for the contaminated cleaning fluid.
  • the cleaning fluid is atomized during the washing process and the mist is returned through the return line within the housing.
  • a suction fan sucks the cleaning fluid mist, used cleaning fluid and dirt particles back out of the housing interior.
  • the disadvantage here is that the suction takes place in the housing. As a result, not only does the wash brush dry out faster, but the contaminated cleaning fluid, paint particles, paper dust, etc. are also sucked into and taken up by the wash brush.
  • organic solvents e.g. based on chlorine and glycol
  • the washing results are still satisfactory.
  • cleaning fluids commonly used on a vegetable basis the washing brush quickly clogs up. This has a negative impact on the quality of the washing result and leads to longer washing times.
  • the object of the invention is to develop a cleaning device which prevents the escape of cleaning fluid or cleaning fluid vapors, paint particles and dirt at the housing opening without contaminating the cleaning element accommodated in the housing.
  • the cleaning device essentially consists of a cleaning element which is accommodated in a housing.
  • the cleaning element can be a cleaning cloth or a washing brush.
  • the housing is provided with an opening to the adjacent printing press cylinder.
  • the cleaning device can be turned on and off on the lateral surface of the printing press cylinder and, in the case of printing press cylinders with gripper bridges, can be lifted off the printing press lateral surface in their area.
  • a suction device is assigned to the opening of the housing of the cleaning device. The mixture of cleaning fluid, cleaning fluid vapor, paint particles, dirt etc. is prevented from escaping from the housing by suctioning directly at the opening. The suction takes place in the gap between the housing with a corresponding opening of the cleaning device and the cylinder surface.
  • a rotary printing press known per se is shown with two printing units 12 and a coating unit 13 arranged downstream in the direction of sheet travel.
  • Each printing unit 12 has, inter alia, a blanket cylinder and an impression cylinder, which are referred to here as printing press cylinder 1.
  • a cleaning device 2 is assigned to each printing press cylinder 1.
  • the painting unit 13 has, inter alia, a forme cylinder and an impression cylinder, which are also referred to here as the printing press cylinder 1.
  • a cleaning device 2 has a housing 4 which has an opening 15 to the adjacent printing press cylinder 1.
  • a cleaning element 3 is arranged in the housing 4, which in the present example is formed by a rotatably mounted, separately driven washing brush. Furthermore, at least one feed for a cleaning fluid, preferably based on vegetable matter and water, a return for contaminated cleaning fluid and a doctor blade (not shown) are arranged in the housing.
  • the housing 4 has an approximately rectangular cross section and extends over the full width of the outer surface of the printing press cylinder 1.
  • the opening 15 in the housing 4 is dimensioned in a known manner so that the cleaning element 3 is in washing position in the contact position with the outer surface of the printing cylinder 1.
  • a gap 14 is present between the housing 4 and the printing press cylinder 1.
  • a suction 5 is arranged at the gap 14.
  • the suction 5 can be arranged completely or only partially surrounding the opening 15.
  • the suction 5 is basically arranged separately from the interior of the housing 4.
  • the suction 5 can be guided outside around the housing 4 or integrated into the wall of the housing 4, separated from the interior.
  • Suction 5 is followed by a line system 6, which is connected to a liquid separator 10 and a filter 7.
  • the filter 7 is coupled to a suction source.
  • the liquid separator 10 is connected to the cleaning fluid circuit 11. The cleaning fluid can be reprocessed in the circuit 11.
  • the mode of action is as follows:
  • the cleaning device 2 is in the parked position with respect to the printing press cylinder 1.
  • the cleaning element 3 has no contact with the printing press cylinder 1. If the outer surface of the printing press cylinder 1 is to be washed, the cleaning element 3 is wetted with cleaning fluid in a controlled manner, driven and set against the printing press cylinder. In the case of gripper bridges, the cleaning device 2 is lifted in this area, air from the environment and cleaning fluid (aerosols), cleaning steam, paint residues, paper dust and other dirt residues from the interior of the housing 4 are extracted via the suction 5, line system 6 to the filter 7 via the gap 14 or aspirated liquid separator 10.
  • the mixture is separated in the filter 7, so that cleaned air is led to the outside via the exhaust air line 8 and residues can be collected in the residue receptacle 9 and disposed of.
  • the line system 6 is interlinked so that each cleaning device in the printing press is connected to the liquid separator 10 and the filter 7 with a corresponding suction source.
  • the suction 5 dries the surface of the printing press cylinder 1 at the same time, in which moisture is also sucked off from the outer surface of the printing press cylinder 1.
  • the cleaning device 2 is switched off by the printing press cylinder 1. The supply of cleaning fluid and the suction are stopped.
