Definitions

  • the invention relates to a sheet support device, which is arranged axially and radially adjustable on a transfer drum of multicolor rotary printing presses, with carriers running in the circumferential direction on the drum jacket, on which the sheet support elements are interchangeably and displaceably attached in the circumferential direction, the sheet being in the working position of the sheet support elements rests on the supporting edge.
  • the printed sheet is transported between the individual printing units by means of transfer drums.
  • the freshly printed side of the sheet can come to rest on the outer surface of the transfer drum, as a result of which the printed image can be damaged by smearing or smearing of the wet ink.
  • a known embodiment of this type uses a wire as a support for the arch support elements, on which they are attached.
  • the arch support elements are slotted in the longitudinal direction.
  • the individual sheet support elements are displaceable on the wire in the circumferential direction of the transfer drum, and the wire with the elements is displaceable in the axial direction of the drum.
  • the disadvantage of the known design is that the adjustment of the sheet support elements to unprinted locations on the sheet to be transferred is complex and complicated. With each setting, either arch support elements must be plugged onto or removed from the wires, the arch support elements having to be stored outside the machine and can also be lost.
  • the wires have no side guide and are therefore very difficult to move laterally. Virtually every element must be moved individually and aligned sideways.
  • the object of the invention is to provide an inexpensive adjustable sheet support device on transfer drums which does not require any additional storage space for the sheet support elements and is easily adjustable to pressure-free locations.
  • the arch-carrying ducks are threaded over bores on ropes which have at least one end with a hook with which they are hooked onto the drum jacket, and that the arch-supporting elements have a square cross section with a center to the bore have protruding support edge and are arranged on a guide belt which can be folded over at right angles, which in turn can be displaced in the axial direction on the outer surface of the transfer drum.
  • This has created a sheet-carrying device which is simple and safe to use and which can be easily adjusted to all printing work occurring in practice. Due to the square cross-section of the arch support elements, they can easily be folded down from the working position to the rest position.
  • the guide strip on its outer periphery a recess, which in their width corresponding to an edge of the square cross section of the sheet supporting members so that the sheet supporting elements with the square cross-section engage in the recess with a folding 90 0th
  • the sheet support elements have a clamping opening with which they are attached to brackets which form a segment of a circle and are displaceable in the axial direction thereof on a guide rod fastened in the transfer drum.
  • the arch support element is designed as a spring steel element and encloses an approximately square opening, wherein it is attached to a bracket with a square cross section.
  • the transfer drum 1 is in a known manner with a Darge provided gripper device, by means of which it takes over the sheet 2 to be transported from the previous grippers and delivers it to the next gripper of a transfer drum or a printing cylinder.
  • the sheet 2 which can have different lengths and widths, lies on the sheet support elements 6 on the drum jacket 3.
  • Spring-elastic cables 4 are tensioned on the drum jacket 3 in the circumferential direction, onto which individual bow support elements 6 having a bore 5 are threaded (FIGS. 1 to 3).
  • the arch support elements 6 are provided with a supporting edge 7 on which the arch 2 is deposited.
  • the sheet support member 6 can be folded from a central, vertical working position on both sides into a rest position (shown in dash-dotted lines). Due to the square cross section of the arch support element, centered on the bore 7, the same engages in any position.
  • each rope 4 has hooks 8 at the ends with which it is hooked onto the drum jacket 9.
  • the sheet support elements 6 are arranged on a guide belt 10 (FIGS. 1 and 3), which in turn is displaceable on the lateral surface 3 of the transfer drum 1 in the axial direction thereof.
  • the guide band 10 is held in place by the rope 4 on the drum shell.
  • the guide band 10 has on its outer periphery a recess 11, the width of an edge of the square cross section of the Bogentrageleme nte 6, so that the arch support elements with the square cross section when folded by 90 ° in engage the recess 11.
  • the arch support element 12 is designed as a spring steel element and encloses an approximately square opening 13. With this opening 13, it is attached to a bracket 14 with a square cross section and also has a supporting edge 15 Edition of sheet 2 on.
  • the bracket 14 is mounted on a guide rod 16 fastened in the transfer drum 1 so that it can be displaced in the axial direction thereof. In addition, it is supported by supports 17 on the drum jacket 9.
