Definitions

  • the invention relates to a Impression cylinder for a sheet-fed rotary printing press and a method for the production of such a printing press cylinder, according to the preamble of claims 1, 24 and 25.
  • Counter-pressure cylinders of sheet-fed rotary printing presses are one Turning device are arranged, and in which the sheet in the beautiful and Reverse pressure operation performed on the upstream impression cylinder and the Trailing edge of the sheet by a gripper device of the downstream Transfer cylinder is taken over, it is known to the bow on the Aspirate and hold the peripheral surface of the cylinder.
  • DE-A-282 8 318 describes a suction roller for transporting Cut from soft paper, for example in manufacturing machines of paper handkerchiefs or paper napkins, in which in the Circumferential surface of the suction roll recesses are arranged, from which Aluminum existing nozzles are pressed, which a variety of in Have circumferential directions of the suction roll slots.

  • Each of the support members has a sandwich structure, in whose middle suction chambers through a meandering curved corrugated sheet be defined, which to the outside of the cylinder by a thin-walled jacket sheet bent according to the cylinder curvature is covered.
  • Each of the chambers is assigned openings in the Cladding sheet is fluidly connected to the environment and can over a Rotary valve can be supplied with suction air to form an arc on the Suction and smooth the peripheral surface of the cylinder. Because of the Formation of the chambers used thin-walled corrugated sheet and thus connected sandwich-like structure of the cylinder is not suitable for Use as an impression cylinder in a printing unit Sheet-fed rotary printing press.
  • EP 0 165 477 B1 describes a sheet-fed rotary printing press with a Known turning device, which one upstream of the turning device Has impression cylinder on which the sheets to be turned are sucked and be held.

Extends from each of the feed channels there are a plurality of radially running bores to the outer peripheral surface of the cylinder body.
  • a structured film is applied, which is in the area of the radially extending Bores is porous or has openings through which one on the Cylinder transported sheet sucked against the peripheral surface or from this can be lifted off.
  • the object of the invention is to be achieved an impression cylinder for one To create sheet-fed rotary printing press, which is easy and inexpensive too is finished and which is both a suction and a blow off on the Cylinder-guided bow allows.
  • Printing press cylinder 1 which preferably as an associated with one Blanket cylinder 2 interacting impression cylinder in one Printing unit 4 of a sheet-fed rotary printing press is used, includes one Base body 8, which in the preferred embodiment of the invention as a casting with cavities 6 and ribs 10, for example made of Gray cast iron etc. is formed.
  • the Printing press cylinder 1 according to the invention preferably in one, one Turning device upstream printing unit 4 used.
  • the turning device is schematically in Fig. 1 by a suction pad, not specified and a turning drum 14 having a take-over gripper are indicated.
  • Printing press cylinder 1 as one between two printing units
  • Fig. 2 are in the base body 8 from the peripheral surface 18 recesses 20th incorporated, for example, after casting the base body 8 in Rough machining of the same can be milled into it.
  • the basic structure of the Recesses 20 or chambers 26 in the peripheral surface 18 of the Basic body 8 already to be provided when casting the basic body 8 and this then rework if necessary.
  • the recesses 20 elements 22 according to the invention in which a multiplicity of Through channels 24 are formed extending from the top of the elements 22 to one located within the periphery of the cylinder 1 Air distribution chamber 26 extend.
  • Air distribution chamber 26 directly as a further recess in the bottom of the Recess 20 formed and can for example in the same way as that Recess 20 in the basic processing of the cylinder body 8 through Milling the same are generated.
  • the air distribution chamber 26 is not closer to one via an air supply line 28 Blown air or suction air source shown connectable, the flow connection between the blown air or suction air source and the Air distribution chamber 26 preferably via one or more in Fig. 1 schematically Valves 30 shown as a block and a control device 32 in the form of a Known rotary union or a rotary valve can be done.
  • the air distribution chamber 26 directly as a recess in the Blow-suction elements 22 according to the invention may be formed.
  • the Air distribution chamber 26 can be, for example, a height of a few millimeters, z. B. 2 mm and extends in the circumferential direction of Printing machine cylinder 1 by several millimeters via the air supply line 28 out.
  • the chamber 26 can extend in sections in the axial direction below one or more of the elements 22 or even over the whole Extend cylinder width.
  • the air distribution chamber 26 only locally below one, for example circular-shaped blowing-suction element 22 as, for example, circular Form recess, such that several circular Air distribution chambers 26 each via separate air supply lines 28 with suction air or blown air can be supplied.
  • the through channels 24 arranged above the air distribution chamber 26 have a diameter in the preferred embodiment of the invention on that is considerably smaller than the spatial extension of the Air distribution chamber 26 and is, for example, in the range between 0.5 mm and can be 1.5 mm.
  • the Through channels 24 in the blowing suction elements 22 one towards Air distribution chamber 26 according to the invention widening cross section have, which in the region of the air distribution chamber 26, for example, up to Triple or multiple of the cross section at the opposite end of the Through channels can be 24.
  • blowing-suction elements 22 preferably made of the same material as the cylinder body 8, z. B. from Gray cast iron are made, but also from another pressure-resistant material, e.g. B. aluminum, steel or fiber-reinforced plastic can be done in inventive manner regardless of the processing of Cylinder base body 8.
  • the plurality of elements 22 formed fine through channels 24 in an advantageous manner with the help of suitable tools such as drill batteries or suitable Laser processing tools are introduced into the elements 22, whereby there are considerable advantages in terms of production technology.
  • the elements 22 can be made directly from one pressure-resistant, roughly porous material, in which the through-channels to Example by foaming or etching or baking at Material manufacturing are produced to manufacture.
