Definitions

  • the invention relates to a sheet support device which is arranged axially and radially adjustable on a transfer drum of multicolour 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 (DE-A 1 179 559) uses a wire as a carrier for the arch support elements, on which they are attached and requires an expensive and cumbersome attachment of the same to the drum to attach the wire.
  • the sheet support elements are slotted in the longitudinal direction and slidable on the wire in the circumferential direction of the transfer drum, the wire itself being slidable with the elements 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, because it is necessary that each time sheet support elements are either attached to the wires or removed from them. These sheet support elements in turn must then be stored outside the machine and can be lost very easily.
  • the wires have no lateral guidance and are therefore very difficult to align laterally. Practically every element has to be moved and aligned individually.
  • the triangular shape of the known arch support elements means that they cannot be folded down from a working position.
  • the still disclosed T-shape of the arch support elements which are guided in appropriately shaped sheet metal holders, only allows them to be displaced in the circumferential direction and also makes it more difficult to replace them.
  • Brackets which extend in the circumferential direction of the transfer drum and which are screwed onto support pieces which can be displaced along the drum axis.
  • support members On the brackets support members are arranged, which have a T-shaped cross section and are also T-shaped grooves of these brackets longitudinally displaceable in the drum direction.
  • This design is also very complex in its construction and therefore expensive and therefore has the same disadvantages as the solution described above.
  • the object of the invention is to provide an inexpensive adjustable sheet support device on transfer drum which is easy to use and does not require any additional storage space for sheet support elements which are not required for a long time and is easily adjustable laterally and in the circumferential direction to pressure-free locations.
  • the arch support elements are threaded through bores on resilient ropes which have at least at one end a hook with which they are hooked onto the drum jacket, and that the arch support elements have a square cross section with a protruding supporting edge centered on the bore and are arranged so that they can be folded over at right angles on a guide belt, which in turn can be displaced in the axial direction of the transfer drum on the lateral surface thereof.
  • This has created a sheet support 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 band has an indentation on its outer circumference which corresponds in width to an edge of the square cross section of the arch support elements, so that the arch support elements with the square cross section snap into the indentation when folded over by 90 °.
  • the Arch support elements have a square clamping opening, with which they are plugged onto stirrups with a square cross-section, 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 bobbin 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 provided in a known manner with a gripper device, not shown, 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 5, 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 in the axial direction thereof on the lateral surface 3 of the transfer drum 1.
  • the guide band 10 is held in place by the rope 4 on the drum shell.
  • the guide band 10 has on its outer circumference a groove 11, the width of which corresponds to an edge of the square cross section of the arch support elements 6, so that the arch support elements with the square cross section when folded over by 90 ° into the Snap groove 11 into place.
  • 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.
