Definitions

  • the present invention relates to a universal mobile upper tool for a waste ejection station in a machine for cutting strip or sheet-shaped elements for the production of packaging, according to the preamble of claim 1.
  • each sheet is introduced one by one into a cutting press. After cutting, each sheet is in the form of several cuts or poses juxtaposed and joined together by attachment points (which will be eliminated later), each pose corresponding to a packaging box. However, the poses do not occupy the entire surface of the sheet; in fact, certain parts, located between two exposures or at the periphery of the sheet, form waste which must be removed from the latter. This is why, as soon as after the cutting station, each sheet is introduced individually into a waste ejection station.
  • This station includes a mobile upper tool provided with pushers and a lower tool in the form of a perforated board. For the ejection of the waste, the sheet having been placed on the lower tool, the upper tool is then moved down so that its pushers force the waste to pass through corresponding openings in the perforated board .
  • Such a universal upper tool consists of a support comprising a plurality of intersecting bars on which are mounted pushers and elastic pressers. By appropriately moving the pushers and elastic pressers along the various crisscross bars, it is possible to adapt the upper tool to each new job.
  • the object of the present invention is to provide a superior tool which eliminates the drawbacks mentioned above.
  • the upper tool represented in FIG. 1, consists of a rectangular horizontal plate 1 squared with elongated holes 10 distributed over almost its entire surface.
  • P1 pushers (only two of which are shown in Figure 1) are fixed, removably and against the underside of the plate 1, using quick-fastening means S1 located on the upper face of the plate 1 and passing through openings 10.
  • the push-pieces P1 can consist either of a single rectangular block 3 which can pivot, along a vertical axis, relative to the fixing S1, or of a block 3 and a needle 2 fixed to the block 3 (for more details see patent application DE-A-1149976 mentioned above).
  • the number and location of blocks 3 and needles 2 are chosen so that they are capable of pushing the waste through the lower tool.
  • the universal upper tool consists of a plate 1 'provided with a large number of holes 10' into each of which can be inserted, from above, a needle 2 'for ejection.
  • Each needle 2 ' is provided, at its upper end, with a head 9 which abuts against the upper face of the plate 1'.
  • a plate 4 (not shown in FIG. 3) placed, during ejection, on the heads 9, prevents the needles 2 'from escaping from the plate 1'.
  • the plate 1 ′ can also be provided with pushers similar (not shown) to those in the form of a block 3 in FIG. 1.
  • the entire lower surface of the plate 1 ′ can be, for example, covered with a VELCRO layer (R ) 7 ′, deposited prior to the production of the holes 10 ′ so that it is perforated simultaneously with the latter.
  • VELCRO (R) bands can be replaced by a fixing system based on the principle of LEGO (R) brand play pads and which is sufficiently well known that it should not be described here in more detail.
