Definitions

  • the invention relates to a device on multicolor printing machines for guiding sheets printed on one or both sides between the printing units or a printing unit and the delivery by means of chain conveyors along a lower continuous guide surface with the aid of air nozzles arranged along the guide surface and connected to flow channels, which act as bores are formed and the areas of which amount to 15 to 30% of the total area and which are supplied by fans arranged in the flow channels of low pressure difference and high volume flow.
  • a device of this type is known from patent application P 34 11 029.
  • sheets printed on both sides can be optimally guided on a blown air stream and sheets printed on one side on a blown air / suction air stream at the highest machine speeds and low paper weight.
  • sheet guiding device for sheet guiding on perfecting machines printing units arranged one behind the other are known, which are connected to one another by sheet guiding cylinders (DE-OS 2 657 250).
  • the sheet guiding device also has sheet guiding brackets in addition to the blow boxes that extend under the sheet conveying path and are adapted to the course of the sheet and provided with outlet openings, which means that the sheets are conveyed in all formats and speed ranges without any creases or greases when processing all types of paper.
  • the disadvantage is that the mechanical support leads to lubrication on the guide bracket if pressure-free areas are missing in the printed image.
  • the object of the invention is to provide a device on multicolor printing machines of the type mentioned, in which, in particular along a steep arc exit, the sheet is smoothed in connection with a positionally stable guidance of sheets printed on both sides by blown air streams which are thin due to the low weight Paper accuracy required can be adjusted to each other.
  • the sheets 1 coming from a feeder 11 are fed to a printing unit 12, printed there and then fed to a second printing unit 13.
  • a turning station 14 is arranged upstream of this second printing unit 13.
  • the sheets 1 can be turned there and then printed on the back in the second printing unit 13, but they can also be turned over the second printing unit 13 for a two-color process pressure can be supplied.
  • the sheets 1 are fed to the delivery 15 after passing through the second printing unit.
  • the transport of the sheets between the printing units 12, 13 or the second printing unit 13 and the delivery arm 15 takes place via chain conveyors, to which grippers 6 are fastened, in two chain circles 16, 17.
  • the sheets 1 are guided on guide surfaces 2.1, each of which Form the top of flow channels 3.1 to 3.6.
  • each flow channel 3.1 to 3.6 fans 8.1 to 8.4 are arranged in openings arranged next to one another.
  • a large number of flow channels form a continuous fan path between the printing units 12, 13 and / or printing unit 13 and the delivery arm 15.
  • the fan path acts as a suction-braking path with switchable or optionally switchable blowing and suction fans 8.1 to 8.4, which ensures flutter-free guidance of sheets printed on one side is achieved at the highest speeds and thin paper.
  • the fan track acts as an air cushion track exclusively with blow fans 8.1 to 8.4, which ensures flutter-free and smear-free guidance of sheets printed on both sides at the highest speeds and thin paper.
  • an upper guide surface 2.2 which forms the underside of flow channels 4.1 to 4.3, is additionally arranged above the guide surface 2.1 within the chain circle 17 in the second printing unit 13.
  • fans 10.1 to 10.4 are arranged in openings arranged side by side. All fans 8.1 to 8.4 and 10.1 to 10.4 are designed as blow fans.
  • the characteristics of the fans 8, 10 have a low pressure with a high volume flow.
  • the guide surfaces 2.1 and 2.2 have holes 7 of the same size, which are regularly distributed on both management areas.
  • the bores 7 have a diameter of at least 15 mm and a distance of approximately 50 mm from one another, corresponding to FIG. 3.
  • the total bore area is 15 to 30% of the total area of the guide.
  • the fluid of the respective guide surface 2.1 or 2.2 has a volume flow of approximately 2,000 m 3 / hour. at a pressure between 30 and 300 Pascal. All fans 8.1 to 8.4 or 10.1 to 10.4 of the double-sided fan track can be adjusted with the accuracy required due to the low paper weight by means of separate controllers which are arranged on the delivery of the printing press.
