Definitions

  • the invention relates to a device for removing knock-out parts from a sheet of material containing blanks or the like, which has a support plate for the sheet of material and a tool holding plate which can be moved vertically to and from the support plate. Break-out elements protruding toward the carrier plate are attached to the tool holding plate.
  • a sheet of material made of paper or cardboard is arranged in a fixed position on the carrier plate.
  • the sheet of material has previously been processed in a punching and grooving device to produce blanks and contains several stripping parts which are removed from stripping elements arranged above the carrier plate.
  • the material sheet also contains an edge waste that must be removed before further processing of the material sheet. This edge waste is largely cut off at the dividing lines in the punching and grooving device and is only held at the remaining sheet of material via small breakpoints.
  • the carrier plate is usually fixed on one side in the device. Since support plates of various sizes are arranged in the device, the support plate lies at a distance from its fixation on a support rod which extends laterally below it to the outside.
  • break-out elements made of steel strip are often arranged on the tool holding plate and are arranged essentially parallel to the edge separating line of the material sheet.
  • the edge waste is bent downwards by the stripping elements. This folding leads to the fact that the stripping element often slides past the folded edge waste without being separated from the rest of the material sheet at the stopping points. The remaining edge waste hinders the further transport of the sheet into a subsequent processing device, which ultimately leads to the machine coming to a standstill.
  • edge waste is completely separated from the sheet of material, since the edge waste occasionally gets stuck on the support rod extending below the carrier plate. This edge waste must also be removed from the device before further processing is possible.
  • the invention has for its object to provide a structurally simple means for removing stripping parts, with which a reliable separation of edge waste from a sheet of material is possible.
  • At least one projection is provided on at least one side edge of the carrier plate, on which an edge separating line of the material sheet lies at least partially, and has at least one separating edge which is essentially parallel to the corresponding edge separating line runs.
  • the stripping elements have at least one tip on the carrier plate side and are arranged in such a way that the tip passes a small distance from the separation edge of the projection when the tool holding plate moves toward the carrier plate.
  • the device according to the invention is simple in construction.
  • the tip ensures that the stripping element can pierce the edge waste and thus a positive connection between the edge waste and the stripping element.
  • the resistance of the edge waste required for the piercing is achieved in that the edge dividing line of the material sheet lies at least partially on the projection. After inserting the tip of the stripping element into the edge waste, the edge waste is cleanly and completely separated from the material sheet when the tool holding plate is moved further downward.
  • the projection advantageously forms a part with the carrier plate. This is particularly advantageous if the carrier plate consists of wood and is cut with laser technology. This makes it possible to position the projection exactly at the required point.
  • a projection is advantageously provided with two separating edges, each of which runs essentially perpendicular to the edge of the carrier plate.
  • the projection is arranged so that the transverse dividing line of the tool material sheet lies on it in the center.
  • Two stripping elements are provided, each of which is assigned to a separating edge.
  • the edge section is transversely separated just above the support rod, so that the edge waste can fall down on both sides of the support rod. This prevents the edge waste from getting caught on the support rod.
  • At least one projection is provided with a separating edge which runs essentially parallel to the edge of the carrier plate.
  • the stripping element is preferably made of steel strip with vertical and horizontal narrow sides. At least one tip is arranged in the middle of a vertical narrow side. This is preferably the vertical narrow side facing the edge dividing line of the material sheet.
  • Such a configuration of the stripping element enables the stripping element to be reliably inserted into the edge waste.
  • the distance of the tip of the stripping element from the separating line is approximately 1.5 mm and from the separating edge is approximately 1 mm.
  • the distance of the tip of the stripping element from the separating line is approximately 2 mm and from the separating edge is approximately 1.5 mm.
  • the device for removing stripping parts has an upper horizontal tool plate 10 and a horizontal support plate 12 arranged at a distance below it.
  • a sheet of material 14 made of paper, cardboard or corrugated cardboard is arranged in a fixed position on the carrier plate 12 and has previously been processed in a punching and creasing device (not shown) for the production of blanks.
  • the material sheet 14 has been processed in the punching and grooving device so that an edge waste 19 along a longitudinal dividing line 16 and a transverse dividing line running perpendicular to this is separated from the rest of the material sheet 14 so that the edge waste 19 only is still connected to the rest of the material sheet 14 by way of breakpoints 17.
  • the material sheet 14 rests on the carrier plate 12 such that the longitudinal dividing line 16 runs parallel and at a lateral distance from the side edge 18 of the carrier plate 12.
  • the carrier plate 12 has two projections 24 which extend outward from its side edge 18.
  • the projections 24 form a part with the carrier plate 12, so that the bearing surface of the carrier plate 12 merges flatly into the bearing surface of the projections 24.
  • the projections 24 have separating edges 26 running parallel to the side edge 18 of the carrier plate 12.
  • the material sheet 14 is placed on the carrier plate 12 so that the longitudinal dividing line 16 rests on the projection 24.
  • the support plate 12 rests on a support rod 22 which extends outward from the side edge 18 of the support plate 12. Above the support rod 22, the support plate 12 has a projection 28.
  • This projection 28 has two separating edges 30, 32 which extend vertically from the side edge 18 of the carrier plate 12.
  • the projection 28 also forms a part with the carrier plate 12.
  • the sheet of material 14 is arranged so that the transverse dividing line 20 is located in the middle of the projection 28, with both dividing edges 30, 32 running parallel to the transverse dividing edge.
  • the projection 28 extends so far that the outer edge of the workpiece sheet 14 rests on it.
  • stripping elements 34, 36 and 38 made of steel strip are attached to the tool holding plate 10.
  • the stripping elements 34, 36 and 38 extend vertically downward from the underside of the tool holding plate 10.
  • the stripping elements 34, 36 and 38 have their vertical narrow sides tips 40 which protrude from the horizontal narrow side of the stripping elements 34, 36 and 38.
  • the design of the stripping elements is described in more detail in German Patent P 4124098.7.
  • the stripping elements 34 assigned to the projections 24 are arranged on the tool holding plate 10 in such a way that they extend perpendicular to the separating edge 26. As can be seen in FIG. 3, the stripping element 34 with the tip 40 facing the separating edge 26 passes the separating edge 26 at a distance b.
  • This distance b is approximately 1 mm when processing a material sheet from a 0.5 mm thick cardboard and approximately 1.5 mm when processing a material sheet from a 2 mm thick corrugated cardboard.
  • the distance a from the tip to the longitudinal dividing line 16 of the material sheet 14 is 1.5 mm when processing a material sheet from a 0.5 mm thick cardboard and approximately 2.0 mm when processing a material sheet from 2 mm thick corrugated cardboard.
  • the stripping elements 36 and 38 assigned to the projection 28 are arranged on the tool holding plate 10 on both sides of the projection 28 parallel to the side edge 18 approximately in the middle of the edge drop 19.
  • the break-out elements 36 and 38 with the tip 40 facing the respective separating edge 30, 32 pass the separating walls 30, 32 at a short distance.
  • This distance is preferably 2 mm when processing cardboard and preferably 3 mm when processing corrugated cardboard.
  • the tips 40 of the stripping elements 34, 36 and 38 are arranged at one level.
  • Square blocks 42 preferably made of wood, are also attached to the tool holding plate 10.
  • the surface of the side edge 18 of the carrier plate 12 facing Square cuboid 42 runs parallel to the longitudinal dividing line 16 above the edge drop 19. It is somewhat closer to the longitudinal dividing line 16 than the tips 40 of the stripping elements 34.
  • the underside of the cuboids is arranged somewhat higher than the tips 40.
  • the tips 40 of the break-out elements 34, 36 and 38 facing the separating edges 26, 30, 32 pierce at a short distance from the separating edges 26, 33 and 32 in the edge waste 19. Because the longitudinal dividing line 16 and the transverse dividing line 20 are each on the projections 24 and 28, the edge waste 14 cannot easily bend along the dividing lines 16, 20, so that the tip 40 of the respective stripping element 34, 36 and 38, respectively Resistance is opposed, which is sufficient that the tip 40 can penetrate into the edge waste 19 to the extent that a positive connection is ensured. After this positive locking has been achieved, the edge waste 19 is cleanly separated from the rest of the material sheet 14 at the holding points 17 during a further downward movement of the tool holding plate 10.
  • the edge waste 19 is separated into two parts along the transverse dividing line 20, which can fall down on both sides of the supporting rod 22. This prevents the edge waste 19 from getting caught on the support rod 22.
  • the tool holding plate 10 is lowered until the edge waste 19 is completely separated from the material sheet 14.
  • the tool holding plate 10 is then moved up again, the sheet of material is conveyed on to the next work station, and a new sheet of material 14 is inserted into the device.
