Definitions

  • the invention relates to a device and a method for removing processed workpieces from a production plant, wherein the production plant z. B. may be a press, in particular a large-scale transfer press, a press line, a transfer press or the like.
  • productivity has been increased considerably in recent years.
  • today's production speed is often no longer limited by the production speed of the actual production line but by the speed with which the workpieces or press parts produced by the production lines can be conveyed away from the line.
  • the US 5,692,593 shows a system for automatically distributing workpieces from a press to first and second conveyors, respectively, in two vertically spaced planes.
  • the plant comprises lower conveyors and upper conveyors as well as distribution conveyors for the distribution of the workpieces on the lower or upper conveyors.
  • Workpieces are conveyed in two parallel paths in the press transport direction, the left-hand workpieces are transported from the left conveyors to the left palletizing positions, the right-hand workpieces are transported from the right conveyors to the right palletizing positions.
  • the transverse conveyors are belt conveyors.
  • the FR 2 966 137 A1 (Peugeot Citro ⁇ n) relates to a device for transporting workpieces, for example body parts, at the end of a press line.
  • This has a linear conveyor, which extends transversely to the press transport direction and along which a plurality of storage stations are arranged.

  • the space required in the workpiece transport direction is minimized.
  • z As large-scale transfer presses, press lines or the like, this is advantageous.
  • the web preferably extends perpendicular to the workpiece transport direction, but smaller deviations (of, for example, less than 20 °) are possible if required.
