Definitions

  • the invention relates to a feeder for a sheet processing machine and a machine for processing substrate sheets according to the preamble of claims 1 and 12, respectively.
  • feeders are used to separate sheets of different materials prepared in stacks and feed them to the printing press.
  • the sheets are separated and fed using so-called sheet separators.
  • sheet separators In the area of the upper front of the stack, i.e. H. On the stack side facing in the conveying direction, a swiveling sheet flap is provided.
  • Such feeders can differ in further details depending on the application and the nature of the sheet.
  • a feeder for a sheet processing or processing machine with at least one transport tool being provided, through which a top sheet of a picked-up stack can be transported in a transport direction away from the stack into a downstream transport path, and a sheet flap is provided on the downstream side of the stack, which is between a position in which it is located with a stop surface in the transport path of a sheet to be conveyed from the feeder, and a position in which it releases the transport path intended for transport , can be moved.
  • the requirements for the design or position of the sheet flap can vary depending on the substrate to be processed. Also can the material thickness or stiffness or deviations from the ideal arch geometry, e.g. B. a deformed or curved arch geometry, losses in the possible production speed or require measures to adapt the arch flap. In addition to, for example, existing deviations in the arch geometry, e.g. B. existing deformations in the stacked sheets, the leading edge may also sink to a greater or lesser extent due to gravity and get caught on the sheet flap when the sheet is conveyed out of the feeder.
  • ideal arch geometry e.g. B. a deformed or curved arch geometry
  • Deformations can also occur due to sagging of a sheet that is already supported in the leading area of the sheet by subsequent conveying means but is still held in the trailing area by the sheet separator, or due to the rear area of a sheet that has been bent downward due to deformation falling off. In both of the latter cases, a collision between the swiveling-back arch flap and the underside of the arch can occur from below and a resulting disruption in the operation of the feeder.

  • the advantages that can be achieved with the invention are, in particular, that this provides an investor that is less sensitive to changing substrate properties.

  • the flexible or resiliently deformable contact element can, on the one hand, largely eliminate or at least reduce the risk of hitting the front edge during transport and the associated tearing or snagging for a larger range of substrates and, on the other hand, the risk of disruption due to the above-mentioned collision of the sheet flap swiveling back the underside of the bow can be reduced.
  • Such problems can occur in particular when feeding sheets with a greater stiffness than simple paper sheets of small to medium grammage and thickness, such as those that occur, for example, with papers of large grammage and thickness of, for example, more than one millimeter or even with sheets made of cardboard, including cardboard Corrugated cardboard, or a composite of layers with a thickness of more than one, in particular more than two millimeters, is present.
