Definitions

  • the invention relates to a sheet transfer drum according to the preamble of claim 1.
  • DE-PS 36 02 084 shows a sheet transfer drum which has three times the diameter of the plate cylinder.
  • This drum is designed so that the movement space required for rigid substrates has been removed from the full cylinder. This leaves an almost triangular contour. This contour has the advantages mentioned in the patent.
  • the drum can be supplemented by sheet support elements to form a full cylinder.
  • the surface of this full cylinder can in turn be provided with an anti-lubrication coating.
  • DE-PS 35 36 536 and DE-PS 35 36 442 describe further solutions with foldable slats, which should enable adaptation to the printing material.
  • lubrication protection must be achieved by blowing air. These devices can only process a small range of substrates.
  • the use of blown air combined with very high operating and installation costs must also be aimed at freedom from greasing.
  • such solutions cannot be used for the particularly rigid materials.
  • Adjusting the slats to match the substrate is extremely time-consuming, if not impossible, for the operator due to the inaccessibility of the machine and the many setting parameters.
  • the object of the invention is to provide a sheet transfer drum with a double-large diameter which, without complex set-up times, all printing materials available on the market, i.e. Cardboard boxes, papers can be processed without smudging.
  • a contour as described in claim 1 enables a flutter-free and smear-free removal of even very thin or stiff sheets from the preceding printing cylinder.
  • a transported sheet is moved over the sheet guide plate below the transfer drum in such a way that in the maximum case the trailing edge of the sheet slides along the surface of this sheet guide plate.
  • the trailing edge of the sheet only abuts the guide surface of the sheet transfer drum. Therefore, the object of the invention can be used not only for straight printing but also for face and reverse printing for all types of cardboard and paper.
  • the outlines of the transfer drum 1, which take over the sheets 3 to be transported from a printing cylinder 4 and transfer them to the subsequent printing cylinder 5 of the next printing unit, are composed of two geometries or specially shaped side surfaces 2, as shown in FIG. 1. Over the side surfaces 2 sheet guide plates 6 are attached to the drum core 7, the shape of which is adapted to the shape of the drum core 7.
  • the blade effect of the drum contour is illustrated with the aid of FIG. 4.
  • the design of the contour geometry generated on the drum core by guide surfaces of the drum core or the sheet guide plates takes place in addition to the consideration of aforementioned trajectory also taking into account the pressure conditions and air turbulence when rotating the drum.
  • Negative and positive pressure mutually support each other as shown schematically and in a straight line in the development according to FIG. 4.
  • the overpressure zone 17 located above sheet 3 passes under the sheet under consideration.
  • the vacuum zone 16 in the diffuser area (extension) of the transfer drum 1 Supported by the vacuum zone 16 in the diffuser area (extension) of the transfer drum 1, the sheet 3 floats on this air and is guided contactlessly on both sides, which is particularly important in the case of perfecting.
  • the bow end 21 is pressed in the confuser zone of the drum by the overpressure effect 17 against the guide plate 18. Due to the curvature of the baffle, the contact occurs only at the rear edge, where the arc separates the overpressure and vacuum zones.
  • the flow around the rotating blade contour should be as turbulent as possible. Therefore, the outlet of the guide surface 11 is rounded off at the level of the gripper bridge and executed at an obtuse angle to the guide surface. Due to the so-called Coanda effect, the flow around the edge of the guide surface 11 of the sheet guide plate 6 takes place in such a way that the one flowing above the side surface or the sheet guide plate Air does not get under the sheet 3 already delivered to the next printing cylinder 5. A blowing up of this bow end is avoided.
  • the cross section of the drum core 7, the side surfaces 2 of which can be designed as guide surfaces, is thickest in the direction of the axis x, but narrowest in the area of the gripper bridges. Nevertheless, this drum core 7 has the greatest distance from the theoretical drum circumferential line 22 in the region of the axis x of the cross section.
