Definitions

  • the invention relates to a method for separating plate-shaped workpieces made of wood or wood substitute materials.
  • plate-shaped wood or wood substitute materials for example in the production of furniture
  • plate-shaped workpieces with desired dimensions for further processing.
  • plate-shaped workpieces are thereby separated out also plate-shaped semi-finished and thereby isolated.
  • the separation of the workpieces from the semi-finished products according to specified patterns takes place. These are regularly chosen so that the blend is low, i. that the largest possible total area of further processable materials is obtained from a plate-shaped semifinished product.
  • the invention is therefore based on the object to provide a method for separating plate-shaped workpieces made of wood or wood substitute materials, which can be carried out with shorter processing times.
  • a plurality of cuts is made, preferably starting from the edge contour of the semifinished product. During the making of these cuts, the individual areas of the semifinished product, which later form the individual workpieces, remain a coherent structure. The separation of the workpieces is then carried out by another, the individual cuts connecting section. This cut preferably runs through the end points and / or end regions of the previously made cuts, so that a comb-like pattern results. The achievement of one of the previously made cuts by the further cut leads to the separation of a workpiece, i. for completely separating a portion forming the workpiece from the remaining semi-finished product.
  • the line is preferably straight, but may for example also have a stepped course.
  • a kind of strip of workpieces which are isolated with a common further cut.
  • further strips of workpieces can then preferably be produced by repeating the singulation method described above.
  • the cutting pattern is preferably characterized essentially by the fact that the strip-shaped semi-finished products border against the passage direction of the semifinished product during processing at a common cutting line.
  • the wall contours of the workpieces to be separated pointing in the conveying direction can have very different geometries.
  • the edge contour of the semifinished product entering into the processing according to the method according to the invention is processed, specifically at the edge contour pointing in the conveying direction or passage direction.
  • a plurality of cuts are then first made by the method according to the invention, which are then connected by the further cut for separating the individual workpieces.
  • the individual workpieces are held by a fixing device during the execution of the cuts, in particular during the implementation of the further cut for separating the workpieces.
  • the fixation advantageously of the workpiece and / or the remaining semi-finished product, in particular at the moment of its complete separation from the remaining semi-finished product, has a positive effect on a clean execution of the cuts, since until complete completion of the cutting operation, the position, in particular both to be separated plate areas, is ensured.
  • the fixing device is designed so that it is able to fix all workpieces of a strip of the pattern at the same time.
  • a plurality of fixing devices may be present, which are the fixing of individual workpieces of a strip allow each associated with the individual workpieces fixing.
  • cuts are made by milling.
  • Milling has the advantage that almost any cutting geometry or pattern can be realized.
  • the cutting direction of a milling cutter can be changed abruptly during the execution of the cut.
  • the Fig. 5 and 6 show the semi-finished product Fig. 1 immediately before and after the implementation of the further cut for separating the workpieces by the method according to the invention.
  • a plate-shaped semifinished product 1 first runs in a conveying direction X into the region of the material used for carrying out the method and not shown processing device a.
  • the method according to the invention can now be carried out, for example, in an order of the processing steps that result from the Fig. 1 . 2 . 3 . 5 and 6 results.
  • a plurality of cuts 4 are made with a suitable processing unit, such as a cutter, in the example shown, starting from the, preferably in the conveying direction X facing edge contour 6 in the plate-shaped semifinished product 1, preferably against the conveying direction X, run in and in the, preferably transversely to the conveying direction X extending, direction Y, the individual workpieces 2.1 to 2.7 separate from each other. While carrying out these process steps, the workpieces 2.1 to 2.7 remain connected to the remaining semifinished product 3.
  • a suitable processing unit such as a cutter, in the example shown, starting from the, preferably in the conveying direction X facing edge contour 6 in the plate-shaped semifinished product 1, preferably against the conveying direction X, run in and in the, preferably transversely to the conveying direction X extending, direction Y, the individual workpieces 2.1 to 2.7 separate from each other. While carrying out these process steps, the workpieces 2.1 to 2.7 remain connected to the remaining semifinished product 3.
  • workpieces - as in the example shown, the workpieces 2.8 and 2.9 - to provide, which are arranged between the edge contour of the semifinished product and the actual formed from the workpieces 2.1 to 2.7 strips.
  • workpieces 2.8 and 2.9 which may also be scrap pieces, are separated between the implementation of individual sections 1 ending in the semifinished product 1 by means of correspondingly angularly guided cuts 5.
  • the semifinished product 1 After carrying out the cuts ending in the semifinished product, the semifinished product 1 has the in Fig. 5 represented geometry. To the in Fig. 6 shown separation of the strips 7 forming workpieces 2.1 to achieve 2.7, a further section 8, which connects the semi-finished in the cuts together. Through the section 8, the workpieces are 2.1. to 2.7 isolated. The remaining region of the semifinished product 3 can now be analogous to that containing the workpieces 2.1 to 2.9 Cutting pattern are processed according to another preferably also strip-shaped pattern, preferably until the semi-finished product 1 has been completely processed into workpieces.
