Definitions

  • the invention relates to a delivery device on sheet-fed rotary printing presses according to the preamble of patent claim 1.
  • the sheets are to be placed on a stack at a practically reduced speed. In practice, this means that the sheets must be slowed down over a short distance and then placed on the stack.
  • suction roller A disadvantage of this suction roller, however, is that it is built quite large and cannot be attached close enough to the paper stack.
  • the object of the invention is to create a driven suction roll for a delivery device on a sheet-fed rotary printing press, with which it is possible to keep the distance between the suction roll center and the stacking edge as small as possible; in addition, the sheet to be braked is to be stripped across its width during the braking process, i. H. Wrinkles are smoothed.
  • the advantages that can be achieved with the invention are, in particular, that it is possible during the braking process gangs to strip out the sheet from the middle of the sheet to the outside on both sides, and that part of the suction roller can be made inactive according to the sheet format width to be processed.
  • the outside diameter of the suction roller can be kept as small as desired, and suction air does not have to be supplied from the inside.
  • a driven suction roller 1 is mounted in a known manner in side frames of a sheet delivery device, not shown. As is also known, it can be moved in and against the sheet transport direction in order to position the suction roll 1 as close as possible to the rear side of the stack, in accordance with the paper format.
  • the suction roller 1 is designed as a solid body and is provided with a plurality of bores 2 which intersect the axis of rotation of the suction roller 1. You have e.g. B. a diameter of 4 mm.
  • the holes 2 are each on a left of a roller half, respectively. right rising spiral line around the suction roll 1, the holes 2 are each offset by 10 0 on the circumference and about 6 mm to each other.
  • suction air supply pieces 3 that are sealed off from one another over the entire length of the suction roller 1 provided with bores 2 arranged side by side.
  • the individual suction air feed pieces 3 are adapted to a radius "r" of the suction roll 1 and sealed against the ambient air in such a way that no outside air can enter between the suction roll 1 and suction air feed pieces 3.
  • Each suction air supply piece 3 is provided in the center with a longitudinal groove 4 which is connected to a connecting pipe 6.
  • Each of the connecting pipes 6 is connected to a shut-off valve 8 assigned to it via a hose 7. All shut-off valves 8 are connected via tubes D between pipes to a suction air source, not shown.
  • the suction air of each individual suction air supply piece 3 can be adjusted or switched off via the shut-off valves 8.
  • a table 9 is provided in the opposite direction to the sheet transport direction.
  • a surface 11 of the table 9 is arranged slightly below the highest point of the suction roll 1.
  • the table 9 is provided on its surface 11 with outlet openings 12 for blowing air.
  • the outlet openings 12 are designed such that they allow the air flow to emerge along the surface 11, as a result of which the paper sheet is drawn against the table 9 in accordance with the "hydrodynamic" paradox.
