Description

Die Erfindung betrifft ein Verfahren zur beleglosen Übergabe von Zuschnitteilen von einem rechnergesteuerten Zuschnittsystem an ein rechnergesteuertes flexibles Fertigungssystem.The invention relates to a method for the paperless transfer of blank parts from a computer-controlled cutting system to a computer-controlled flexible manufacturing system.

Von automatischen Schneidsystemen, die beispielsweise in der textilverarbeitenden Industrie eingesetzt werden, werden in einem Arbeitsgang Zuschnitte unterschiedlicher Konfektionsgrössen hergestellt.Automatic cutting systems, which are used, for example, in the textile processing industry, produce blanks of different sizes in one operation.

Um den Fertigungsprozess zu rationalisieren, werden sehr häufig flexible Fertigungssysteme eingesetzt, wo die Zuschnitteile an einer Übergabestation in die Förderanlage des Systems eingegeben und dann rechnergesteuert in der entsprechenden Reihenfolge an den entsprechenden Arbeitsplatz transportiert werden, s. z.B. EP-A-0206936.In order to rationalize the manufacturing process, flexible manufacturing systems are very often used, where the cut parts are entered at a transfer station into the conveyor system of the system and then computer-controlled in the appropriate order to be transported to the appropriate workplace, see. e.g. EP-A-0206936.

Damit in dem sich anschliessenden Fertigungsprozess keine Verwechslung stattfindet und nur Teile gleicher Grösse miteinander vernäht werden, muss vor der Entnahme jedes Teil mit einem entsprechenden Beleg, beispielsweise einem Klebeetikett versehen werden.So that no confusion takes place in the subsequent manufacturing process and only parts of the same size are sewn together, each part must be provided with a corresponding document, for example an adhesive label, before removal.

Bei der Übergabe müssen die Daten des Belegs (Materialqualität, Farbe, Grösse, Art des Halbfertigteils, usw.) in die Steuerung des Fertigungssystems eingegeben werden, was entweder manuell über ein Terminal oder unter der Voraussetzung, dass die Belege entsprechend kodiert sind, mittels eines Lichtgriffels geschehen kann.When handing over the data of the receipt (material quality, color, size, type of Semi-finished part, etc.) can be entered into the control of the production system, which can be done either manually via a terminal or, provided that the documents are coded accordingly, using a light pen.

Dies ist nicht nur zeit- und damit kostenintensiv, sondern der Fertigungsprozess ist auch störanfällig, wenn beim Kennzeichnen die Etiketten verwechselt werden oder der Beleg während des Transportes der Zuschnitteile verlorengeht.This is not only time-consuming and therefore costly, but the manufacturing process is also prone to failure if the labels are mixed up during labeling or if the document is lost during the transport of the cut parts.

Ferner besteht die Gefahr, dass bei der manuellen Eingabe der Daten des Belegs Tippfehler nicht erkannt werden. Bei flexiblen Fertigungssystemen hat eine Falscheingabe schwerwiegende Folgen, weil entweder das falsche Teil von der Näherin gar nicht erkannt wird und die Verarbeitung zwangsweise zu Ausschuss führt, oder aber das falsche Teil erkannt wird, der weitere Fertigungsprozess aber solange unterbrochen werden muss, bis das richtige Zuschnitteil zur Hand ist.There is also the danger that typing errors will not be recognized when the data of the document is entered manually. In the case of flexible production systems, incorrect entry has serious consequences, because either the wrong part is not recognized by the seamstress and the processing inevitably leads to rejects, or the wrong part is recognized, but the further production process must be interrupted until the correct cut part is at hand.

Um diese Nachteile abzustellen, liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur beleglosen Übergabe von einem automatischen Zuschnittsystem an ein flexibles Fertigungssystem anzugeben.To overcome these disadvantages, the invention is based on the object of specifying a method for the paperless transfer from an automatic cutting system to a flexible manufacturing system.

Die Lösung der Aufgabe erfolgt durch die im Kennzeichenteil des Hauptanspruchs angegebenen Mittel. Weiterbildungen des Verfahrens sind den Unteransprüchen entnehmbar.The task is solved by the means specified in the characterizing part of the main claim. Further developments of the method can be found in the subclaims.

Mit diesem Verfahren werden bei der Übergabe alle bisherigen Fehlerquellen ausgeschaltet und die Zeitspanne von der Beendigung des Zuschnitts bis zur Aufnahme der Zuschnitteile im flexiblen Fertigungssytem wesentlich verkürzt.With this procedure, all previous sources of error are switched off and the The time span from the completion of the cut to the start of the cut parts in the flexible manufacturing system is significantly reduced.

Nachfolgend soll das erfindungsgemässe Verfahren näher beschrieben werden.The method according to the invention will be described in more detail below.

Die einzige Figur zeigt rein schematisch die Anordnung eines flexiblen Fertigungssystems, das hier nur durch einen Teil seiner Förderanlage 3 dargestellt ist, einer automatischen Schneidanlage 1, beispielsweise eine Höchstdruck-Fluidstrahl-Schneidanlage, mit der zugehörigen Abräumstation 2 und einer Projektionsvorrichtung 5.The single figure shows, purely schematically, the arrangement of a flexible production system, which is represented here only by part of its conveyor system 3, an automatic cutting system 1, for example an ultra-high pressure fluid jet cutting system, with the associated clearing station 2 and a projection device 5.

Die Schneidanlage 1, die Projektionsvorrichtung 5 und das flexible Fertigungssystem werden jeweils durch die elektronischen Steueranlagen 4, 6, 7 gesteuert, die untereinander in elektronischer Verbindung stehen können. Nach dem Zuschnitt der Einzelteile auf der automatischen Schneidanlage 1 fährt die Palette 1a, auf der der Zuschnitt erfolgte, mit den Zuschnitteilen in die Abräumstation 2. Von hier müssen die Zuschnitteile an die Förderanlage 3 übergeben werden.The cutting system 1, the projection device 5 and the flexible production system are each controlled by the electronic control systems 4, 6, 7, which can be in electronic communication with one another. After the individual parts have been cut on the automatic cutting system 1, the pallet 1a on which the cutting was carried out moves with the cut parts into the clearing station 2. From here, the cut parts must be transferred to the conveyor system 3.

Damit der Zuschnitt automatisch ausführbar ist, sind die gewünschten Konturdaten jedes Einzelteiles in Form einer Parameterschar Pn, die auf einen frei wählbaren Bezugspunkt Po (Xo, Yo) bezogen ist, in der Steuereinrichtung 4 der Schneidanlage 1 gespeichert. Dieser Bezugspunkt Po sollte in vorteilhafter Weise auf die Palette 1a bezogen sein. Durch diese Parameterschar Pn ist jedes Teil sowohl von seiner Lage als auch von seiner Form definiert und kann durch Angabe eines einzigen Punktes Pi (Xi, Yi) ― bespielsweise des jeweiligen Flächenschwerpunkts ― auf dem Zuschneidetisch (auf der Palette 1a) identifiziert werden.So that the cutting can be carried out automatically, the desired contour data of each individual part are stored in the control device 4 of the cutting system 1 in the form of a family of parameters Pn, which is related to a freely selectable reference point Po (Xo, Yo). This reference point Po should advantageously relate to the pallet 1a. This set of parameters Pn defines each part both in terms of its position and its shape and can be specified by specifying one single point Pi (Xi, Yi) - for example of the respective center of gravity - can be identified on the cutting table (on the pallet 1a).

Wenn die Palette 1a mit den Zuschnitteilen in die Abräumstation 2 transferiert wird, bleibt die Identifikationsmöglichkeit erhalten, da auch der Bezugspunkt Po mitverschoben wird. Für den Fall, dass der Bezugspunkt Po ortsfest gewählt wurde, kann ein neuer Bezugspunkt P1 durch die Angabe P1 = Po + P (X, Y) definiert werden, wodurch die angesprochene Identifikationsmöglichkeit der Zuschnitteile wieder hergestellt ist.If the pallet 1a with the cut parts is transferred to the clearing station 2, the identification possibility remains, since the reference point Po is also shifted. In the event that the reference point Po has been selected to be stationary, a new reference point P1 can be defined by specifying P1 = Po + P (X, Y), as a result of which the mentioned identification possibility of the cut parts is restored.

Um von der Förderanlage 3 an den jeweils richtigen Arbeitsplatz innerhalb des flexiblen Fertigungssystems gebracht werden zu können, ist die Angabe eines Identifikations-Parameters Pi (Flächenschwerpunkt) nicht ausreichend, sondern es müssen weitere Parameter ergänzt werden. Diese Parameter sind beispielsweise die Materialart Pm (z.B. Leder), die Farbe Pf, die Art des Halbfertigteiles Ph (z.B. Ärmel oder Kragen) usw. Die Auswahl der zusätzlichen Parameter ist davon abhängig, wie die weitere Verarbeitung aussieht und muss so getroffen werden, dass innerhalb des flexiblen Fertigungssystems nur durch die Angabe der Parameter eine eindeutige (maschinenlesbare) Identifikationsmöglichkeit geschaffen ist.In order to be able to be brought from the conveyor system 3 to the correct workplace within the flexible manufacturing system, the specification of an identification parameter Pi (area focus) is not sufficient, but additional parameters have to be added. These parameters are, for example, the material type Pm (e.g. leather), the color Pf, the type of semi-finished part Ph (e.g. sleeves or collar) etc. The selection of the additional parameters depends on what the further processing looks like and must be made so that within the flexible manufacturing system, a unique (machine-readable) identification option is only created by specifying the parameters.

Diese Parameter werden in die Steuerung 6 des flexiblen Fertigungssystems eingegeben und dort gespeichert.These parameters are entered into the controller 6 of the flexible manufacturing system and stored there.

Für die Übergabe der Zuschnitteile von der Abräumstation 2 an die Förderanlage 3 kommt es nun darauf an, ob dabei eine bestimmte Reihenfolge eingehalten werden muss, oder ob die Flexibilität des Fertigungssystems so gross ist, dass jedes Teil unabhängig vom Zeitpunkt seiner Übergabe anschliessend dem richtigen Platz zugewiesen werden kann.For the delivery of the cut parts from the Clearance station 2 to the conveyor system 3 now depends on whether a certain sequence must be followed, or whether the flexibility of the production system is so great that each part can then be assigned to the correct place, regardless of the time of delivery.

Dementsprechend muss die Steueranlage 6 programmiert werden. Mittels eines geeigneten Computerprogrammes wird dann ggf. die Reihenfolge von der Steueranlage 6 festgelegt.The control system 6 must be programmed accordingly. The sequence may then be determined by the control system 6 using a suitable computer program.

Es ist selbstverständlich, dass die Berechnung der Reihenfolge auch ausserhalb der Steueranlage 6 vorgenommen werden kann und anschliessend in diese erneut eingegeben wird.It goes without saying that the calculation of the sequence can also be carried out outside the control system 6 and then entered again in this.

Dieses Programm der Übergabe-Reihenfolge wird ausserdem in die Steuereinrichtung 7 der elektronischen Projektionseinrichtung 5 eingespeist.This program of the transfer order is also fed into the control device 7 of the electronic projection device 5.

Die Projektionseinrichtung 5 ist so ansteuerbar, dass sie ein optisches Signal auf eine vorgegebene Stelle wirft. Solche Projektionseinrichtungen sind bekannt und werden beispielsweise in der Leiterplatten-Fertigung eingesetzt, um dem Montagepersonal die Stelle, an der das jeweilige Bauteil eingesetzt werden soll, anzuzeigen. Auf der Zeichnung ist oberhalb der Abräumstation 2 eine Umlenkeinrichtung 9, beispielsweise ein Spiegel, so angeordnet, dass das projizierte optische Signal indirekt auf die zu entnehmenden Teile geworfen wird.The projection device 5 can be controlled in such a way that it throws an optical signal at a predetermined point. Projection devices of this type are known and are used, for example, in printed circuit board production in order to indicate to the assembly personnel the location at which the respective component is to be used. In the drawing, a deflection device 9, for example a mirror, is arranged above the clearing station 2 in such a way that the projected optical signal is indirectly thrown onto the parts to be removed.

Dies ist insbesondere dann von Vorteil, wenn die Abraümstation relativ grossflächig ist, da die erreichbare Ablenkung des Projektionsstrahls bauartbedingt ist. Selbstverständlich könnte die Projektionseinrichtung 5 auch direkt über der Abräumstation 2 angeordnet werden.This is particularly advantageous if the clearing station has a relatively large area, since the deflection of the projection beam that can be achieved is dependent on the design. Of course, the projection device 5 could also be arranged directly above the clearing station 2.

Nach dem Zuschnitt wird nun von der Projektionseinrichtung 5 ein optisches Signal auf das jeweils von der Abräumstation 2 zu entnehmende, an die Förderanlage 3 zu übergebende Zuschnitteil projiziert. Dieses optische Signal kann auf den durch den Parameter Pi angegebenen Flächenschwerpunkt des entsprechenden Teils projiziert werden.After cutting, an optical signal is now projected by the projection device 5 onto the cutting part to be taken from the clearing station 2 and to be transferred to the conveyor system 3. This optical signal can be projected onto the centroid of the corresponding part specified by the parameter Pi.

Sowohl die Steuereinheit 7 als auch die Steuereinheit 6 sind mit einer von der Bedienungsperson geführten Quittungstaste 8 verbunden. Jedesmal wenn das optisch markierte Zuschnitteil an die Förderanlage 3 übergeben wurde, wird die Quittungstaste betätigt. Eine geeignete Programmauswahl in den Steuereinheiten 6, 7 stellt sicher, dass sowohl die Informationen, welches Teil (welche der Parameter) gerade von der Förderanlage 3 aufgenommen wurde und in das flexible Fertigungssystem übertragen wird, als auch die Anweisung an die Projektionseinrichtung 5, das nächste zu entnehmende Teil optisch zu markieren, ausgeführt wird.Both the control unit 7 and the control unit 6 are connected to an acknowledgment button 8 guided by the operator. The acknowledgment button is actuated each time the optically marked cutting part has been transferred to the conveyor system 3. A suitable program selection in the control units 6, 7 ensures that both the information as to which part (which of the parameters) has just been picked up by the conveyor system 3 and is transferred to the flexible production system, as well as the instruction to the projection device 5, the next one to optically mark the part to be removed is executed.

Um mehrfache Programmierarbeit und Eingabefehler zu vermeiden, können in die Steuereinheiten 4, 6, 7 jeweils dieselben Parameter von einem einzigen Datenträger eingelesen werden. Das Basisprogramm jeder der Steuereinheiten 4, 6, 7 ist so gestaltet, dass die jeweils nicht benötigten Daten nicht übernommen werden, was die Einlesezeit verkürzt, oder nicht benutzbar sind.In order to avoid multiple programming work and input errors, the same parameters can be read into the control units 4, 6, 7 from a single data carrier. The basic program of each of the control units 4, 6, 7 is designed such that the data that is not required in each case is not taken over, which shortens the reading time or cannot be used.

In einer weiteren Lösung der Aufgabe kann das Abräumen aus der Abräumstation 2 und die Übergabe an die Förderanlage 3 von einem Manipulator, einem sogenannten Roboter, vorgenommen werden.In a further solution to the problem, the clearing from the clearing station 2 and the transfer to the conveyor system 3 can be carried out by a manipulator, a so-called robot.

Dieser Roboter erhält ebenfalls von einer elektronischen Steueranlage, die die zuvor beschriebenen Parameter verwendet, jeweils einen Befehl, ein bestimmtes Teil von der Abräumstation 2 zu entnehmen und an die Förderanlage 3 zu übergeben. Da auch der Roboter nur die Angabe eines bestimmten Punktes benötigt, um zur Entnahme die richtige Stelle über der Abräumstation 2 anzufahren, kann auch hierbei beispielsweise der den Flächenschwerpunkt jedes Zuschnitteiles beschreibenden Parameter Pi verwendet werden.This robot also receives a command from an electronic control system that uses the parameters described above to remove a certain part from the clearing station 2 and to transfer it to the conveyor system 3. Since the robot also only needs to specify a certain point in order to move to the correct location above the clearing station 2 for removal, the parameter Pi describing the center of gravity of each blank part can also be used here.

Die weitere Programmierung eines solchen Roboters und dessen mechanische Ausgestaltung, nämlich, dass einerseits das gewünschte Teil entnehmbar ist und auch entnommen wird und andererseits die erfolgte Übergabe quittiert wird, ist seit langem hinreichend aus dem Gebiet der automatischen Fertigung bekannt und bedarf daher keiner gesonderten Erläuterung.The further programming of such a robot and its mechanical design, namely that on the one hand the desired part can be removed and also removed and on the other hand that the transfer has been acknowledged, has long been sufficiently known from the field of automatic production and therefore does not require a separate explanation.

Selbstverständlich ist es auch denkbar, anstelle mehrerer Steueranlagen 4, 6 7 nur eine einzige elektronische Steuerung zu verwenden, die die Überwachung und Steuerung aller Systeme übernimmt.Of course, it is also conceivable to use only a single electronic control system instead of several control systems 4, 6 7, which controls and monitors all systems.
