Definitions

  • the invention relates to a printing press for cleaning the supplied, in particular sheet or sheet-shaped printing medium is provided with a cleaning device, the one extending perpendicular to the printing medium conveying direction, with air outlets directed towards the print carrier conveyor track Compressed air line which is substantially centered within a slot nozzle connected to a suction air source is attached such that on both sides of the compressed air line Partial slots are formed.
  • the cleaning device described in DE-20 06 716 for extracting dust to be fed from a printing press web-like print media was basically the right idea based on a combined compressed air-suction air system Optimize cleaning effect.
  • the graphic Representation of DE-20 06 716 A largely representative for the dimensions of the known cleaning device the two individual suction slots and the Suction box receiving compressed air line (blow box) a total width, which is about 14 to 19 times the opening width of the Compressed air outlets correspond while the compressed air line (Blow box) has a total width that is about the 10- to 14 times the width of the compressed air outlets.
  • the invention is based, that of the known task To fix device-inherent disadvantages described above.
  • the invention provides that the air outlets have a diameter of 2 - 4 mm, preferably 2.5 - 3 mm, and that the slot nozzle including those taken up by the compressed air line Width has a total width in the range of 15-25 mm.
  • the suction slots in the immediate vicinity of the Arrange compressed air outlets to ensure that already Dust particles detached from the print carrier do not reappear can deposit on the print carrier by the total width the slot nozzle including the compressed air line only about corresponds to 6 times the diameter of the compressed air outlets.
  • the solution dealt with in claim 4 is the subtask to keep the environmental impact as low as possible.
  • Figure 1 shows a schematic representation of a printing press A with impression cylinder 3 and sheet transfer roller 4, each with Bow grippers 3.1 and 4.1 are equipped.
  • the impression cylinder 3 rotates in the direction of arrow f1
  • the sheet transfer roller 4 rotates in the direction of arrow f2.
  • the housing B are the print media to be printed, e.g. in the form of sheets of paper, saved piled up in a stack.
  • the single ones Bows are made from the housing B in the usual and not to the invention belonging way via a transfer station C, the one Has transfer table 5, through a print carrier insertion slot 6 of the sheet transfer roller 4 fed and each individually to the Transfer printing cylinder 3.
  • the jacket of the printing cylinder 3 is a cleaning device delivered, which schematized in the figure 1 shown way connected to a suction air source Includes slot nozzle 2 with compressed air line 1 therein.
  • the pressure-suction air system contains a vacuum chamber 7, the suction air connection 12 and a suction line 9 is connected to a suction blower 10, whose compressed air nozzle directs the polluted air towards the Blows arrow f3 into an air dedusting device 13 into which Rinse water 14 is filled, which by means of a swirl nozzle 15 is whirled up.
  • the cleaned air is not over one shown connection derived.
  • a converter 16 may be connected to the suction fan 11.
  • the invention At the front end of the vacuum chamber 7 is the invention Slot nozzle 2, in the parallel running a compressed air line 1 is inserted, the air outlets 1.1 Area of the outer slot opening.
  • the compressed air line 1 is essentially in the middle slot nozzle area arranged such that the compressed air line 1 on both sides Partial slots 2-2 are formed.
  • spacers 22 At the front end of the slot nozzle 2-2 spacers 22 are attached.
  • the compressed air line 1 is connected via a compressed air connection 17 a pressure line 11 connected.
  • the compressed air system includes a pressure regulator 18 with an upstream pressure vessel 19, the a compressor 20 is connected upstream.
  • the compressed air line 1 extends over the total length of the slot nozzle 2-2.
  • the slot nozzle 2 has an overall width in the area of 15 - 25 mm, a part of this width of the Compressed air line 1 is taken.
  • Compressed air line 1 compressed air inflated onto the paper sheets, which creates a fluidized bed or flickering effect to loosen particles adhering to the paper surface be sucked off directly through the slot nozzle.
  • the blowing pressure and the suction pressure are infinitely adjustable to ensure that Precisely coordinate the relationship between compressed air and suction air to be able to.
  • a pressure of approximately is preferred 400 to 700 kPa worked.
  • the printing press A can also use sheet material instead of single sheets supplied in the housing B e.g. in shape a roll of paper is stored.
