Definitions

  • the present invention relates to a method of cutting parts from a plate or sheet material, in particular animal skins or fabric, according to templates having predetermined shapes and dimensions.
  • overlapping templates can result from imprecise placement, or from an error related to the system for capturing the position of templates when the use of such a system is part of the cutting process, before cutting properly. said.
  • the cut is carried out with a cookie cutter, the first cut piece is good, and the second has a defect, but it is difficult to choose in a simple and safe way the order of cutting the pieces.
  • One of the aims of the present invention is to propose an automatic cutting process which makes it possible to choose in advance the consequences of the overlapping of at least two templates, whether voluntary or not.
  • the choice of the type of cut may be interesting to leave the choice of the type of cut to the operator who arranges the templates on the material. For this, and according to the present invention, it will have one or more additional distinctive signs at desired locations, possibly on the template itself, characteristic of the desired cutting mode in one or more overlapping zones.
  • the two choice methods can be used simultaneously in a complementary way.
  • FIG 1 two templates 1 and 2 have been placed so that they have an overlapping area 3, hatched in the figure, and their respective contours are superimposed at two points of intersection 4 and 5.
  • the templates 1 and 2 are provided with distinctive signs A, B, C, D and A ', B', C 'D' characteristic of their respective shapes and dimensions.
  • FIG. 2 illustrates the different steps of the method according to the invention. Only the part of this flowchart included in the dashed line frame, as well as the taking into account of the choices made in the overlapping zones, underlined in the wording of the corresponding step, correspond to the invention. If all of these steps are performed by a computer, the list of possible cutting types can be loaded into an electronic memory and / or onto any information storage medium such as, for example, magnetic tapes or disks or disks hard, the contents of which can be read by the computer.
  • any information storage medium such as, for example, magnetic tapes or disks or disks hard, the contents of which can be read by the computer.
  • Figure 6a partially shows two templates 1 and 2 which overlap on an overlapped area 3, hatched, and whose contours overlap at two intersection points 4 and 5.
  • Figure 6b partially shows the two parts 1 'and 2 '' of cut sheet or sheet material, in the overlapping zone, according to a first cutting mode of the process of the present invention, according to a straight line joining the intersection paints 4 and 5.
  • Parts 1 'and 2 ' correspond to templates 1 and 2 respectively.
  • Figure 8a partially shows two templates 1 and 2 which overlap on an overlapped area 3, hatched, and whose contours overlap at two intersection points 4 and 5.
  • Figure 8b partially shows the two parts 1 'and 2 '' of cut sheet or sheet material, in the overlap zone, according to a third cutting mode of the process of the present invention, according to an average line equidistant from the contours of the templates joining the points of intersection 4 and 5.
  • the pieces 1 'and 2' correspond respectively to templates 1 and 2.

Claims (5)

1. Insbesondere automatisches Verfahren zum Ausschneiden von Materialstücken in Platten-oder Blattform, das die Anordnung von Schablonen (1, 2) mit den Formen und Maßen der Stücke, das Erkennen der jeweiligen Formen, Maße, Ausrichtungen und Anordnungen der Schablonen auf der Platte oder dem Blatt des Materials mittels bestimmter Zeichen (A, B, C, D, A', B', C', D'), die charakteristisch für ihre jeweiligen Formen und Maße sind, und das Ausschneiden des Platten- oder Blattmaterials entlang den von den Schablonen definierten Umrissen umfaßt, dadurch gekennzeichnet, daß es weiter das Aufspüren eventueller Überlappungen von Schablonen und die Veränderung des Ausschneidens in den Überlappungsbereichen (3) von Schablonen enthält, entweder durch Ausschneiden entlang eines geraden Segments (6), das die Schnittpunkte der Umrisse der überlappenden Schablonen verbindet, oder durch Ausschneiden entlang einer von den Schablonenumrissen gleich weit entfernten mittleren Linie (9), die die Schnittpunkte (4, 5) der überlappenden Schablonenumrisse verbindet, oder auch durch Ausschneiden entlang dem Umriß (7, 8) der einen oder der anderen sich überlappenden Schablonen, wobei die Auswahl der Schnittarten in den Überlappungsbereichen (3) in jedem Überlappungsfall in Abhängigkeit von der Art der Schablone und dem betroffenen Teil des Umrisses der Schablone getroffen wird und diese Wahlen in eine Liste von möglichen Schnittarten eingetragen werden können, die direkt nach dem Aufspüren und der Identifizierung der Überlappungsfälle konsultiert werden kann.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß alle oder ein Teil der Arbeitsgange des Aufspürens von Überlappungsbereichen, der Befragung der Liste von möglichen Schnittarten und der Auswahl der Schnittarten in den Überlappungsbereichen zum Ausschneiden des Platten- oder Blattmaterials und die Steuerung des eigentlichen Schneidens von einem Computer mit entsprechender Software durchgeführt werden.
3. Verfahren nach Anspruch 2, dadurch gekennzeichnet, daß die Liste der möglichen Schnittarten in einen elektronischen Speicher und/oder irgendeinen Informationsträger wie Magnetbänder oder -disketten oder Festplatten geladen wird, deren Inhalt vom Computer gelesen werden kann.
4. Verfahren nach einem beliebigen der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß die Auswahl der Schnittart von zusätzlichen bestimmten Zeichen abhängen kann.
5. Verfahren nach Anspruch 4, dadurch gekennzeichnet, daß die zusätzlichen bestimmten Zeichen von einer Bedienungsperson auf das Materialblatt oder die Materialplatte aufgebracht werden.
