Definitions

  • the invention relates to a device for cleaning the lateral surfaces of cylinders in rotary printing machines, with one extending over the length of the cylinder Cleaning cloth and with a cooperating with it Pressure element, the cleaning cloth through the Pressing element can be pressed against the moving lateral surface is and the pressing element from one with an internal pressure actable elastically deformable hollow body, which expands elastically when the internal pressure is applied.
  • the object is achieved in that the Air supply to the hollow body via a two-way valve is carried out and that the two-way valve of overpressure is switchable to negative pressure, so that the hollow body of an outward stretched position over a neutral Rest position is moved to an inwardly stretched position.
  • the cleaning device with the invention Design assigned to a pressure cylinder, so during a negative pressure is applied to the operation of the machine, so that the gripper fingers without damaging the cleaning cloth can happen.
  • the hollow body is in a neutral rest position in which the cleaning cloth does not Has contact with the cylinder surface.
  • the hollow body is made of a rubber-like Material made, so with this configuration Relatively low overpressure or underpressure is a simple solution of the task at hand.
  • a cylinder 1 of a rotary printing press is for Clean the outer surface 2 of a pressure element 3 one Assigned cleaning device. via the pressure element 3 a cleaning cloth 4 can be pressed onto the outer surface 2, with which the outer surface 2 of the rotating cylinder 1 of Dirt and paint residues can be cleaned.
  • the pressing element is an advantageous embodiment from an elastically deformable hollow body 5, for. B. from a rubber-like material that in a mounting rail 6 is recorded.
  • a hose connector 7 On the mounting rail 6 is for air supply a hose connector 7 is provided with a Two-way valve 8 is connected.
  • the two-way valve 8 is with a compressed air generator 9 and a suction air generator 10 coupled so that depending on the position of the two-way valve 8 the Air supply of the hollow body 5 from positive pressure to negative pressure is switchable.
  • the two-way valve 8 is in one position drawn in which the hollow body 5 with negative pressure is acted upon.
  • the hollow body 5 is dash-dotted and shown in dotted lines in a neutral rest position.
  • the hollow body 5 presses the Cleaning cloth 4 on the outer surface 2.
  • dashed the inwardly expanded position of the hollow body 5 reproduced when a negative pressure is applied.
  • the solution is thus a substantially increased distance 11 between employee and employee position of the Cleaning cloth 4 to the outer surface 2 of the cylinder 1 reached. It can be clearly seen here that the hollow body 5 one without air in the neutral rest position has a convex cross-section on the outside.
