  • the position of the blank part in the pattern must be corrected before da. Well, where the mismatch has been detected, then actually cut. This process is called Matching.

It remains typical to the knowledge of the worker reserved, in which order he works off the individual characteristic points, if necessary, a blank part as an essential part (master part) be given. The worker therefore requires an extremely high level of qualification and requires a considerable amount of time for high-quality end products to stir the alignment. In particular, when the pattern of the pattern is relatively small, great care is required.

  • the invention is further developed by the features of the dependent claims.
  • the invention further relates to a computer program and a Computcrprogrammprodiikt for the execution of the method.
  • the invention is initially based on the knowledge that it is possible to determine already when determining the pattern which points are selected characteristic points taking into account the repeat of the pattern. In addition, it can already be determined when determining the pattern whether alignment with respect to a determination of the characteristic points has an influence on the position of other characteristic points and it would be necessary to carry out their alignment. That is, the selected characteristic points can already be evaluated in terms of their importance and interdependence already in the determination of the pattern.
  • a characteristic point will result that has the highest valence, the alignment thus has influence on all other cut parts and their characteristic points. It can be determined already in the determination of the pattern and the corresponding selected characteristic points, whether in the case of a deviation of the result in the point from the theoretical point contained in the pattern, a correction in the longitudinal direction, a correction in Que ⁇ ichtung or a correction in both longitudinal As well as in the transverse direction is required in order to achieve the final goal, namely the pattern matching of the various blank parts after cutting.
  • the method according to the invention it is possible, starting from the programmed and previously defined pattern of the characteristic points, to approach the sequence indicated by the valence in a controlled manner and to display there, preferably optically, the corresponding point on the designed product.
  • the worker can then determine in a simple manner on site, whether the characteristic point in the pattern in the pattern pattern of the pattern pattern deviates from the existing existing in the actual good point. In the given case, the worker causes a corresponding correction of the deviation, ie a corresponding correction in the programmed pattern, whereupon then the next selected selected point is automatically marked, and so on.
  • the program instructions of a cutting program created on the basis of the previously determined pattern of cuts can be corrected accordingly and can be adjusted after the output aligned with the previously defined pattern has been moved out conveyed to the cutting device and cut accordingly.
  • the extent of moving the Zuscluüttmaschine in the pattern are limited insofar as individual blank pieces in their arrangement in the actual running pattern cutting the arrangement of other blank parts within predetermined tolerances may not cut. It is therefore convenient to associate a surrounding boundary with each of the blank sections within which such movement of the blank section may occur.
  • a typical influencing variable is the repeat of the pattern. A repetition of the entire alignment process will offer itself before the alignment process is recognized as not feasible and appropriate alarm is given.
  • the correct alignment procedure can be carried out programmatically, the program interactively executing, if necessary, the marking of the individual characteristic points and the detection of deviations and thus the determination of the corresponding corrections.
  • the invention also relates to a computer program product containing such a program.
  • the correction in a low-valued function already has to account for a correction to be made at a higher-valued characteristic point, it is convenient to store each deviation and then supply all the stored arrays to the cutting program at the cutting table, since the corrections are only for the one currently being designed Apply well and be completely different on the next designed item, even if it is the same item with the same pattern and pattern.

If the good bears a pattern in the repeat, it must be ensured when laying out that the laying takes place stress-free, in particular in order to avoid distortion of the repeat. In the case of multi-layer design, care must also be taken to ensure that the patterns in the different layers are completely identical. This is generally fixed by so-called needling. A fixation of one or more layers can also be done by means of negative pressure in a conventional manner.
  • This designed cut is to be cut to a cutting table 3 according to a predetermined pattern 2 determined by a designer, for example.
  • the predetermined pattern 2 is typically fed to a computer 4, which converts the cutting lines of the pattern 2 into control commands, which in turn are fed to a cutting device S of the cutting table 3 and cause them to extend the corresponding cutting operations when the material to be cut on the table surface 6 of the cutting table 3 is in a predetermined Refercnzlage.

  • the cutting tool which is arranged on the cutting head 8 may also be d ⁇ eh.bar. This is especially the case when the cutting tool carries an oscillating or rotating knife. This is basically known and commercially available in many implementations.
  • an alignment table 10 is provided between the delivery table 1 and the cutting table 3 for this purpose.
  • a worker determines, for each blank portion 21 to 26 of the pre-determined pattern 2, whether the pattern of the pattern at the corresponding corresponding location coincides with the actual pattern of the pattern in the laid item, judging whether this could be critical to the quality of the final product and, when a deviation is considered critical, causes the corresponding blank portion to be virtually moved relative to the other blank portions until the pattern matches the pattern in that blank portion with the pattern of the pattern at the laid out item. It may be a longitudinal and / or transverse movement of the corresponding blank part, and optionally also a rotation.
  • Points can already be determined in the development of the pattern 2 and have further found that there are hierarchical dependencies, that is, there are blank parts in which a change in the arrangement of another blank part also makes a change in their arrangement necessary, and such where this is not necessary. Thus, a valence can be assigned to each of these characteristic points. Furthermore, there is a point of highest significance, in which a correction movement has an influence on all other cut parts, but whose arrangement is not influenced by corrective movements of the other blank parts. Typically, this point of highest significance is assigned to a blank part referred to in practice as a master part. This will be explained in more detail with reference to FIG. 2 and FIG.

Abstract

L'invention concerne un procédé de découpage de matériaux plans conformément à un patron, en particulier d'un matériau plan mou en flexion tel qu'un tissu, lequel présente un motif selon un rapport répété. Le procédé consiste à effectuer un positionnement, ou mise en correspondance, au cours de laquelle des points caractéristiques des pièces individuelles d'un patron, respectant le rapport du motif, sont utilisées. Lors du positionnement, les points caractéristiques ne sont pas seulement choisis, mais également évalués en fonction de leur importance et de leur interdépendance. Le positionnement est effectué d'abord en fonction du point présentant la valeur de priorité la plus élevée, puis progressivement en fonction des points présentant la valeur immédiatement inférieure, éventuellement suivant une structure hiérarchique arborescente. Ce procédé permet ainsi d'aborder chaque point, et d'évaluer nécessité d'un positionnement pour ledit point, par un processus automatique commandé par logiciel.
