Definitions

  • the invention relates to a cylinder washing device in which a washcloth is on the surface of the cylinder to be washed can be pressed by a pressure element, the pressure element consists of an elastic rubber membrane, which is assigned to a carrier.
  • a device is known from DE 30 05 469 C2, in which essentially a supply roll, a pressing element and a take-up roller are provided. That on the supply roll located washcloth is removed from this, passed over the pressure element and from of the recording role. The pressure element presses the washcloth, which was previously can be moistened against the jacket of the cylinder to be washed.
  • the pressure element consists of a membrane-like elastic skin, which is in a U-rail is held such that a cavity is formed between the two. Will this When the cavity is pressurized, the membrane expands and presses the washcloth against it the outer surface of the cylinder to be washed.
  • the size of the contact area between the washcloth and the outer surface of the cylinder across the width of the cylinder to be washed is not the same remains. It depends on the pressure distribution in the cavity between the U-rail and the membrane from.
  • the elasticity of the membrane is not constant. Because the elasticity the membrane must be ensured, the membrane is relatively thin, so that its damage when passing bumps on the surface of the cylinder to be washed (e.g. gripper channels, gripper back) cannot be excluded.
  • a doctor device for a roller washing device is known from DE 33 09 557 A1. This is used to scrape off the washing liquid from the roller surface. Doing so a profile hose with a closed profile is used, attached to its from the roller facing surface is attached to a support. The profile hose is connected to the air pressure Adjustable surface of the roller. The surface facing the roller is at least one Squeegee bridge provided.
  • This device is intended for a different washing principle and can be used for washing not be used in a washcloth.
  • the object of the invention is therefore to develop a device for washing cylinders, in which a washcloth is pressed against the surface of the item to be washed Cylinder is pressed, the pressing element is simple and robust is and when pressing the washcloth with the width of the contact surface of the washcloth the cylinder always remains the same over the length of the cylinder.
  • the advantage of the solution according to the invention is that the profile hose according to the invention easy to manufacture or inexpensive as a purchased part in the relevant trade is related.
  • the prior art see the above DE 33 09 557 A1
  • the sealing surfaces required there are omitted, since there are no sealing clamps on the support profile.
  • the invention will be explained in more detail below using an exemplary embodiment.
  • the drawing shows a washing device with the solution according to the invention.
  • the washing device essentially consists of a Supply roll 1, a take-up roll 3 and a washcloth 4, which has a pressing element 2 is pressed against the outer surface of a cylinder 7 to be washed.
  • the supply roll 1 consists of a spindle 11 on which a supply roll 12 is wound is.
  • the take-up roll 3 with its spindle 31 serves to hold the supply roll 2 withdrawn washcloth 4.
  • the washcloth 4 becomes a take-up winder on the spindle 31 32 wound up.
  • the supply roll 1 and the take-up roll 3 are mounted in the side walls 51 of the frame 5.
  • the spindles 11; 31 are driven as required by a motor, not shown, wherein the motor is preferably arranged within one of the two spindles 11, 31 is.
  • a spray tube support 52 is provided in the frame 5, which carries a spray tube 6.
  • the Wash cloth 4 is guided over the side of the pressing element 2 facing the cylinder 7.
  • the pressing element 2 consists of a carrier 21, to which a rubber membrane 22 is assigned and can be supplied with compressed air via an air supply 23.
  • the rubber membrane 22 is according to the invention as a profile tube with a closed Profile formed, which is closed at its ends, not shown in the figure. This In the simplest case, closure can take place in that the ends are outside the pressure area be sealed by vulcanization.
  • the side facing cylinder 7 is provided with a rubber membrane 22 with a web 24.
  • the The web has a flat contact zone 26 facing the cylinder.
  • the rubber membrane 22 On its side facing away from the cylinder 7, the rubber membrane 22 has a reinforced one Foot 25, which is fixedly connected to the carrier 21.
  • the foot 25 In the example shown in the figure the foot 25 is glued to the carrier, but it can also be connected to it by rails be tense.
  • the foot itself has at least one air passage opening 27 that the air supply 23 is assigned. But it is also possible to have several evenly across the width to provide the washing device with distributed air passage openings 27 which are connected to the air supply 23 are connected.
  • the washcloth 4 is now pulled off the supply roll 12 and wound onto the spindle 31 to form the take-up reel 32.
  • the washcloth 4 is guided over the side of a pressure element 2 facing the cylinder 7.
  • the washing cloth 4 is fed in steps or continuously.
  • a pressure medium preferably compressed air, is applied to the rubber membrane 22. so that the side facing the cylinder 7 with the web 24 with its Contact zone 26 is shifted in the direction of the cylinder 7 to be cleaned and the washcloth 4th presses against the cylinder 7.
  • the washcloth 4 can be moistened beforehand via the spray tube 6 become.
