Bearbeitungszentren dieser Art sind als Portal- oder Ausleger-Konstruktionen seit langem in den verschiedensten Ausführungsformen bekannt.Machining centers of this type have been known for a long time in various embodiments as gantry or outrigger structures.
Bei den Portal-Konstruktionen (vgl. beispielsweise
Bei den Ausleger-Konstruktionen überspannt ein Kragarm die Bearbeitungsbereiche.In the boom designs, a cantilever spans the machining areas.
Unter einem Bearbeitungsbereich ist jede Art von Bearbeitungsauflage zu verstehen, auf der die plattenförmigen Werkstücke abgelegt und in irgendeiner Weise bearbeitet werken können. Bekannt sind in diesem Zusammenhang herkömmliche Tischkonstruktionen, sogenannte Konsolen- oder Rastertische oder auch Kombinationen dieser Tischkonstruktionen.A processing area is to be understood as any type of processing support on which the plate-shaped workpieces can be deposited and worked in any way. Conventional table constructions, so-called console or grid tables or combinations of these table constructions are known in this context.
Zur Durchführung der Bearbeitungsvorgänge müssen die Werkstücke auf den Bearbeitungsbereichen unverschiebbar fixiert werden. Hierzu werden Aufspanneinrichtungen eingesetzt, die die Werkstücke mechanisch oder pneumatisch auf den Tischkonstruktionen halten. Bekannt sind in diesem Zusammenhang mechanische Einrichtungen, wie-Niederhalter, sog. Klemmspanner, oder pneumatische Einrichtungen, sog. Saugspanner o.dgl. Einrichtungen, sowie Kombinationen hiervon.To carry out the machining operations, the workpieces must be fixed immovably on the machining areas. For this purpose clamping devices are used, which hold the workpieces mechanically or pneumatically on the table structures. In this context, mechanical devices are known, such as hold-down devices, so-called clamping clamps, or pneumatic devices, so-called suction clamps or the like. Facilities, as well as combinations thereof.
Mit Verfahrensweisen und Bearbeitungszentren der bekannten Art können Werkstücke komplett bearbeitet werden. Dabei wird vorbereitend ein in einem vorangegangenen separaten Arbeitsgang hergestellter Rohzuschnitt auf den jeweiligen Bearbeitungsbereich aufgespannt und dann durch die Bearbeitungseinheit unter Einsatz der für den jeweiligen Arbeitsgang erforderlichen, meist von einem Magazin eingewechselten Bearbeitungswerkzeuge oder Bearbeitungsaggregate die gewünschte Bearbeitung durchgeführt.With procedures and machining centers of the known type, workpieces can be completely processed. In this case, preparatory prepared in a previous separate operation Rohzuschnitt spanned on the respective processing area and then performed by the processing unit using the required for the respective operation, usually substitute a magazine processing tools or processing units, the desired processing.
Das Anordnen und Aufspannen der Rohzuschnitte auf dem Bearbeitungsbereich erfolgt meist von Hand über eine Bedienungsperson, die nach abgeschlossener Bearbeitung die Werkstücke auch wieder von Hand vom Bearbeitungsbereich löst und in einem Zwischenlager ablegt.Arranging and clamping the raw blanks on the processing area is usually done manually by an operator who, after completion of the processing, also manually releases the workpieces from the processing area and places them in an intermediate store.
Die Rohzuschnitte werden meist über eine Sägeanlage aus einer Platte unter Zuhilfenahme eines Optimierungsprogramms (sogenanntes Nesting) herausgelöst.The raw blanks are usually removed from a plate by means of a sawing system with the aid of an optimization program (so-called nesting).
Es ist auch bereits bekannt, anstelle einer herkömmlichen Sägeanlage speziell ausgelegte Bearbeitungszentren einzusetzen und über diese durch Aufteilen der Platten die benötigten Rohzuschnitte herzustellen. Auch in derartigen Fällen werden die aufzuteilenden Platten von Hand in den speziell ausgelegten Bearbeitungszentren angeordnet und die erzeugten Rohzuschnitte nach erfolgtem Aufteilungsvorgang ebenfalls von Hand dem in der Bearbeitungskette nachgeschalteten Bearbeitungszentrum zur abschließenden Bearbeitung zugeführt.It is also already known to use instead of a conventional sawing plant specially designed machining centers and to produce about this by dividing the plates, the required blank blanks. Also in such cases, the plates to be split are arranged by hand in the specially designed machining centers and the generated blanks after the split process also supplied by hand to the processing center downstream in the processing chain for final processing.
Die bekannten Verfahrensweisen haben somit gemeinsam, dass in den jeweiligen Bearbeitungszentren stets zwar spezielle, bei unterschiedlichen Werkstücken auch variierbare Arbeitsschritte durchgeführt werden können, das sogenannte Handling (Zuführen, Aufspannen, Abspannen und Ablegen) jedoch stets von Hand erfolgen muss. Auch werden stark unterschiedliche Bearbeitungsvorgänge, wie beispielsweise das Herstellen von Rohzuschnitten und die daran anschließende Komplettbearbeitung bisher jeweils auf eigens hierfür eingerichteten Bearbeitungszentren vorgenommen, d.h. die notwendigen Prozesse auf mehrere Maschinen verteilt.The known procedures thus have in common that in the respective machining centers, although always special, for different workpieces also variable work steps can be performed, the so-called handling (feeding, clamping, clamping and dropping) must always be done by hand. Also, very different processing operations, such as the production of blank blanks and the subsequent complete processing have been made on each specially set up processing centers, i. the necessary processes are distributed to several machines.
Ferner offenbart die
Aufgabe der vorliegenden Erfindung ist es, eine Verfahrensweise sowie ein Bearbeitungszentrum der beschriebenen Art derart weiterzubilden, dass Handlingsarbeiten für die Bedienungsperson möglichst weitgehend reduziert werden können und ein universeller Einsatz auch hinsichtlich stark unterschiedlicher Bearbeitungsvorgänge möglich ist.Object of the present invention is to provide a method and a machining center of the type described in such a way that handling work for the operator can be reduced as much as possible and a universal Use is also possible with regard to very different machining operations.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a method having the features of claim 1.
Ist dem ersten Bearbeitungsbereich ein Plattenstapelbereich vorgeschaltet und schließt sich an den zweiten oder letzten Bearbeitungsbereich ein Ablagebereich an, kommen gemäß einer Weiterbildung der Erfindung die Schritte des Patentanspruches 2 zum Einsatz.If the first processing area is preceded by a disk stack area and closes at the second or last processing area to a storage area, according to a development of the invention, the steps of
Grundsätzlich kann die gemeinsame Bewegung der Bearbeitungseinheit und der mit dieser gekoppelten Greifeinrichtung in jeder beliebigen Achse erfolgen. Vorteilhaft ist es jedoch, wenn die gemeinsame Bewegung der Bearbeitungseinheit und der mit dieser gekoppelten Greifeinrichtung in einer X-Achse erfolgt und die Bewegung der Greifeinrichtung und der Bearbeitungseinheit in einer Y-Achse unabhängig voneinander ist.In principle, the common movement of the processing unit and the coupled thereto gripping device in any axis can be done. It is advantageous, however, if the common movement of the processing unit and the coupled thereto gripping device in an X-axis and the movement of the gripping device and the processing unit in a Y-axis is independent of each other.
Die gestellte Aufgabe wird ferner mit einem Bearbeitungszentrum mit den Merkmalen des Patentanspruchs 5 gelöst.The stated object is further achieved with a machining center having the features of
Handelt es sich dabei um ein Bearbeitungszentrum, bei dem - in Bearbeitungsrichtung betrachtet - dem ersten Bearbeitungsbereich ein Plattenstapelbereich vorgeschaltet und dem zweiten bzw. letzten Bearbeitungsbereich ein Ablagebereich nachgeschaltet ist, wird die gestellte Aufgabe mit den Merkmalen der Patentansprüche 5 und 6 gelöst.If this is a machining center, in which - viewed in the machining direction - the first processing area is preceded by a plate stack area and the second or last processing area is followed by a storage area, the object is achieved with the features of
Durch die erfindungsgemäße Ausgestaltung des Bearbeitungszentrums wird ein maschinenintegriertes Handlingsystem geschaffen, das die Funktionalität eines derartigen Bearbeitungszentrums erheblich erweitert und die Bedienungsperson von einer Vielzahl von Rüst- und Werkstückhandhabungsaufgaben entlastet.The inventive design of the machining center, a machine-integrated handling system is created, which significantly extends the functionality of such a machining center and relieves the operator of a variety of setup and workpiece handling tasks.
Die Funktionalität eines erfindungsgemäß ausgestalteten Bearbeitungszentrums ist dadurch erweitert, dass für die Bearbeitungseinheit eine sowohl ein Aufteilungsprogramm als auch ein Bearbeitungsprogramm aufweisende Steuereinrichtung und für die Greifeinrichtung eine programmierbare Handhabungsvorrichtung vorgesehen wird.The functionality of a machining center designed according to the invention is extended by providing a control device having both a splitting program and a machining program for the machining unit and a programmable handling device for the gripping device.
Sofern aufgrund des maschinenintegrierten Handlingsystems auf den Einsatz mehrerer jeweils speziell auf einen Fertigungsprozess eingerichtete Bearbeitungszentren verzichtet werden kann, ergibt sich neben einer höheren Produktivität zwangsläufig ein geringeres Investitionsvolumen und ein geringerer Platzbedarf.If, due to the machine-integrated handling system, it is possible to dispense with the use of several machining centers specially set up for a production process, higher productivity inevitably results in a lower investment volume and a smaller space requirement.
Grundsätzlich können die Bearbeitungseinheit und die Greifeinrichtung in jeder beliebigen Weise am Bearbeitungszentrum angeordnet werden. Vorteilhaft ist es jedoch, wenn die Bearbeitungseinheit und die Greifeinrichtung an einem im Wesentlichen waagrecht verlaufenden und quer zu seiner Erstreckungsrichtung horizontal hin und her verfahrbaren Führungsbalken gelagert sind.In principle, the processing unit and the gripping device can be arranged in any way on the machining center. However, it is advantageous if the processing unit and the gripping device are mounted on a substantially horizontally extending and transverse to its extension direction horizontally movable back and forth guide bar.
Die Greifeinrichtung kann an dem Führungsbalken in jeder geeigneten Weise hin und her verfahrbar gelagert sein. Eine besonders vorteilhafte Ausgestaltung ergibt sich jedoch, wenn die Bearbeitungseinheit an der einen und die Greifeinrichtung an der anderen Seite des Führungsbalkens hin und her verfahrbar gelagert ist.The gripping device can be mounted on the guide bar in any suitable manner movable back and forth. A particularly advantageous embodiment, however, results when the processing unit is mounted on the one hand and the gripping device on the other side of the guide bar movable back and forth.
Je nach Art der zu verarbeitenden Werkstücke kann die Greifeinrichtung in der verschiedensten Weise ausgestaltet sein. So kann die Greifeinrichtung mechanische Einrichtungen, wie beispielsweise Hebebacken, Hebezapfen oder Hebeleisten aufweisen. Vorteilhaft ist es jedoch in den überwiegenden Anwendungsfällen pneumatische Einrichtungen, wie Saugheber oder Saugtraversen einzusetzen, zumal diese eine sehr schonende Handhabung auch bei empfindlichen Oberflächen ermöglichen.Depending on the type of workpieces to be processed, the gripping device can be configured in the most diverse ways. Thus, the gripping device may have mechanical devices, such as lifting jaws, lifting pins or lifting strips. It is advantageous, however, in the majority of applications, pneumatic devices, such as siphon or Saugtraversen use, especially since this is a very allow gentle handling even on sensitive surfaces.
Bei einem bevorzugten, als Ausleger-Konstruktion konzipierten Bearbeitungszentrum erstreckt sich der als Kragarm ausgebildete Führungsbalken in Y-Richtung, wobei an dessen einer Seite die Bearbeitungseinheit und an dessen anderer Seite die Greifeinrichtung jeweils in Y-Richtung verfahrbar gelagert sind. Bei dieser bevorzugten Ausführungsform ist der Kragarm in X-Richtung entlang einer langgestreckten Maschinenbasis verfahrbar geführt. Bei einem derartigen Maschinenkonzept ist es zweckmäßig, entlang der Maschinenbasis zufuhrseitig einen Plattenstapelbereich, im Anschluss daran einen ersten Bearbeitungsbereich, daran anschließend einen zweiten Bearbeitungsbereich und abfuhrseitig einen Ablagebereich, in X-Richtung jeweils hintereinander liegend anzuordnen.In a preferred machining center designed as a cantilever construction, the guide beam designed as a cantilever extends in the Y direction, the machining unit being mounted on one side thereof and the gripping device being movably mounted on the other side thereof in the Y direction. In this preferred embodiment, the cantilever is movably guided in the X-direction along an elongate machine base. In such a machine concept, it is expedient to arrange a plate stack area downstream of the machine base, followed by a first processing area, then a second processing area and a discharge area on the discharge side, one behind the other in the X direction.
Mit einer derartigen Anordnung kann auf einfache Weise mittels der erfindungsgemäßen Greifeinrichtung die aufzuteilende Platte vom Plattenstapelbereich entnommen und auf dem ersten Bearbeitungsbereich abgelegt und dort mittels der Aufspannrichtung festgelegt werden. Im Anschluss daran führt die Bearbeitungseinheit die notwendige Aufteilung in Rohzuschnitte durch, die nach abgeschlossener Aufteilung mittels der Greifeinrichtung Stück für Stück dem ersten Bearbeitungsbereich entnommen und auf dem zweiten Bearbeitungsbereich abgelegt werden. An diesen Rohzuschnitten erfolgt dann nach dem Festspannen die sogenannte Komplettbearbeitung durch die Bearbeitungseinheit. Nach erfolgter Komplettbearbeitung wird das fertig bearbeitete Werkstück dann von der Greifeinrichtung wieder aufgenommen und im Ablagebereich zum Weitertransport oder zur Weiterbearbeitung abgelegt.With such an arrangement can be easily removed by means of the gripping device according to the invention the plate to be split from the plate stacking area and stored on the first processing area and fixed there by means of the clamping direction. Subsequently, the processing unit performs the necessary division into blank blanks, which are taken after completion of the division by means of the gripping device piece by piece the first processing area and stored on the second processing area. At this Rohzuschnitten then takes place after tightening the so-called complete machining by the processing unit. After complete machining the finished workpiece is then picked up again by the gripping device and stored in the storage area for further transport or for further processing.
