Definitions

  • the invention relates to a cleaning device Rotary printing machines for cleaning the outer surface of Cylinders, with a pressure bar for pressing a Cleaning cloth on the outer surface, with adjusting means for Position the pressure bar and with an elastic Profile rail over which the cleaning cloth is guided and over the cylinder width is pressed against the outer surface.
  • the object is achieved in that as Adjustment means pneumatic cylinders are provided that the Contact pressure on the profile rail via spring elements takes place, which are supported on the pressure bar, and that between the spring elements and the profile rail Even power transmission provided a female connector is.
  • This solution is not only vibration-free
  • the profile rail touches the outer surface, but it is also a compensation of unevenness in the Shell surface guaranteed.
  • the Female connector a uniform pressure of the profile rail achieved so that an optimal over the entire length of the cylinder Cleaning result is achieved.
  • the female connector is attached to the spring bolt and as Steel band formed and the profile rail is on the Interchangeable steel band.
  • the steel band stabilizes here the mounting rail the z. B. from a rubber-like Material can be made. It also broadcasts the Line forces very evenly and still allows one easy replacement of the profile rail.
  • the cleaning device 1 is on a pressure cylinder 2 or by pivoting in its holder 4 on one Blanket cylinder 3 adjustable.
  • the bracket 4 is here provided on both sides between the machine side frames and enables the cleaning device 1 to be expanded.
  • a pressure bar 6 provided, which extends over the cylinder length.
  • the Pressure bar 6 is on both sides via pivot pin 7 on the Support frame 5 pivotally mounted.
  • the pressure bar 6 takes seen over its length on several spring bolts 8, which in Guide bodies 10 are guided.
  • On the guide body 10 act compression springs 11 so that the rail 12 on the Guide body 10 is resiliently supported. about the Profile rail 12, the cleaning cloth 13 is guided.
  • the Nuts 14 on the spring bolts 8 allow adjustment of travel and limit their investment in the Pressure bar 6 the travel ( Figure 2). When pressed State of the rail 12 on the lateral surface of the Cylinders 2, 3 are the nuts 14 from the pressure bar 6 somewhat lifted off.
  • Pneumatic cylinders 19 are fastened on the support frame 5, whose piston rods 20 when pressurized by Roll 21 the pressure bar 6 around the pivot pin 7 after swivel down.
  • the rollers 21 are on roller pin 22 on the pressure bar 6 attached. If the overpressure in the Pneumatic cylinder 19 turned off, so the Pressure bar 6 raised by tension springs 23 so that the Profile rail 12 with the cleaning cloth 13 from the Shell surface 16 is lifted off.
  • the tension springs 23 are between pin 24 on the support frame 5 and pin 25 on the Pressure bar 6 arranged.
  • threaded bolts 26 are provided on the pressure bar Wear locknuts 27, the locknuts 27 in the in FIG.
  • the female connector 9 can as Steel band be formed and also serves as Storage for the profile rail 12. In the shown Execution of the profile rail 12 in the longitudinal direction on the Female connector 9 are pushed on, so that a light Replacing the profile rail 12 is made possible.
