Definitions

  • the invention relates to a device for reducing the speed of sheets during conveying in delivery and feeders of printing presses.
  • Known sheet conveyors of this type are known as suction rolls or as transport means guided over suction boxes.
  • Perforated suction belts or toothed belts are preferably used as the means of transport.
  • a toothed belt is known from US Pat. No. 3,389,908, which is guided in a recess provided with longitudinal grooves in a base plate.
  • the ambient pressure prevails in the recess in order to reduce the friction of the toothed belt.
  • a vacuum prevails in the space between opposing teeth (with one-sided toothing), which is applied via channels arranged laterally in the conveying direction of the toothed belt.
  • a sheet conveying device is known, the toothed belt of which is guided in a base body.
  • Suction channels are arranged laterally within the base body and are designed such that the suction channels are open in the area of the tooth gaps and closed in the area of the teeth.
  • the object of the invention is to develop a device which enables a quick change of the means of transport, the braking of the sheet by means of negative pressure during the conveying continuously and which the sheet to be deposited also in the front region of the deflecting roller facing the stack or the front marks with sufficient holding force leads safely.
  • the present invention due to the increasing cross section of the suction opening, an increased braking effect is realized at high conveying speeds.
  • the negative pressure affects the entire surface and guarantees a holding force right up to the end of the curve.
  • Narrow or wide means of transport can be used depending on the needs (face and back printing, cardboard). Thanks to the two-part structure of the device, the means of transport can be changed quickly. The lower part remains in its position and the upper part is removed from the swivel after loosening the snap connection. If the means of transport are of different widths, only the upper part is replaced.
  • the suction opening can of course also be arranged on both sides of the transport means, coupled with an intake chamber and an air supply. This further increases the holding force.
  • the drive wheel located in the lower part is dimensioned for all suction belt widths.
  • the releasable snap connection is designed to be displaceable to tension the means of transport.
  • the solution according to the invention can be used universally to reduce the speed of the sheets to be conveyed. It can be used in cantilevers and also in investors. Especially when used in feed / lay-up tables, this invention reduces the kinetic energy when the sheets are fed in and the inlet doubling associated therewith.
  • the device is made in two parts.
  • the lower part 12 fixed to the boom has an air supply and receives the rotatably mounted drive wheel 5, which is in engagement with the transport means 1.
  • the upper part 11 is connected to the lower part 12 via a swivel joint 13 and a releasable snap connection 7.
  • the air supply to the lower part 12 is coupled to the suction chamber 4 in the upper part 11.
  • the deflecting roller 8 facing the stack, the deflecting roller 9 facing away from the stack and a tensioning roller 10 are arranged and wrapped around by the transport means 1, in the present example a double toothed toothed belt.
  • a sliding plate 2, which has a wedge-shaped suction opening 3, is arranged on the upper part 11 laterally to the transport means 1 rotating in the conveying direction 6.
  • the mode of action is as follows: A sheet is conveyed to the stack by a gripper system. While the sheet is being conveyed, it is moved over the slide plate 2 in Connection with the transport means 1 transported and sucked from the suction opening 3, tightened and fixed in position. After opening the gripper system, the sheet is braked by the rising part of the suction opening 3 and conveyed in a fixed position to the stack stop.
  • the wedge-shaped suction opening 3 ensures a defined holding force up to the end of the curve.
  • the upper part 11 can be easily separated from the lower part 12 by the releasable snap connection 7 in connection with a swivel joint 13. This means that the means of transport 1 can be exchanged for a short time when worn.
