Ein Maschinengestellt 5 der Biegepresse umfasst im Wesentlichen zwei in Abstand zueinander über einen nicht weiter dargestellten Querverband verbundene, parallel zueinander und in zu einer Aufstandsfläche 6 senkrechten Ebenen erstreckende Seitenständer 7 und einen mit diesen verbundenen Tischbalken 8.. Relativ zum Tischbalken 8, in zur Aufstandsfläche 6 senkrechter Richtung ist in Führungsanordnungen der Seitenständer 7 ein Pressenbalken 9 geführt angeordnet und mit an den Seitenständern 7 bzw. dem Maschinengestell 5 angeordneten Antriebsmitteln 10, zum Beispiel Hydraulikzylinder, elektrische Spindeltriebe, etc. antriebsverbunden.In the Fig. 1 to 3 1 shows a production device 1 for producing bent-formed workpieces with a bending press 2, a handling device 3 and a tool storage 4. A machine position 5 of the press brake essentially comprises two side stands 7, which are connected at a distance from one another and are perpendicular to a footprint 6, and a table joist 8 connected to them. Relative to the desk 8, in relation to the footprint In the vertical direction, a press bar 9 is arranged in guide arrangements of the side stand 7 and is drivingly connected to drive means 10 arranged on the side stands 7 or the machine frame 5, for example hydraulic cylinders, electric spindle drives.

In einander gegenüberliegenden, mit Spanneinrichtungen versehenen Werkzeugaufnahmen 11, 12 ist eine Bestückung mit Biegewerkzeugen 13, zum Beispiel einem Biegegesenk 14 in der Werkzeugaufnahme 11 des Tischbalkens 8 und eines Biegestempels 15 in der Werkzeugaufnahme 12 des Pressenbalkens 9, entsprechend von Vorgaben für den jeweils zu formenden Werkteil und Biegevorgang vorgesehen.In opposite, provided with clamping devices tool holders 11, 12 is an assembly with bending tools 13, for example a bending die 14 in the tool holder 11 of the table beam 8 and a punch 15 in the tool holder 12 of the press bar 9, according to specifications for each to be formed Workpiece and bending process provided.

In Abhängigkeit von den jeweils für eine Serie zu fertigenden Werkteilen oder einer Wartung der Biegewerkzeuge 13 wird in unterschiedlichen Zeitabständen eine Neubestückung und damit ein Austausch der Biegewerkzeuge 13 erforderlich.Depending on the respectively to be produced for a series of workpieces or a maintenance of the bending tools 13 a reassembly and thus replacement of the bending tools 13 is required at different time intervals.

Weiter weist die Fertigungseinrichtung 1 für einen automatisierten Werkteil- und Werkzeugtransfer die Handhabungsvorrichtung 3, zum Beispiel einen Mehrachsroboter 16 mit einer mehrfunktionalen Greifeinrichtung 17, zum Beispiel Zangengreifer, Sauggreifer, etc., an einem Endarm 18 des Mehrachsroboters 16 auf. Der Mehrachsroboter 16 ist in einer Fahranordnung 19 in zu einer Vorderseite 20 des Tischbalkens 8 parallel verlaufenden Richtung verfahrbar.Furthermore, the production device 1 for an automated workpiece and tool transfer, the handling device 3, for example a multi-axis robot 16 with a multi-functional gripping device 17, for example, gripper gripper, suction gripper, etc., on an end arm 18 of the multi-axis robot 16. The multi-axis robot 16 can be moved in a drive arrangement 19 in a direction parallel to a front side 20 of the table beam 8.

Längs einer Rückseite 21 des Tischbalkens 8 und damit innerhalb des Maschinengestells 5 und zwischen den Seitenständern 7 ist längs einer linearen Führungsanordnung 22 eine Anschlagvorrichtung 23, die bevorzugt aus zwei in der Führungsanordnung 22 unabhängig voneinander und über eine Steuer- und Kontrollvorrichtung 24 der Biegepresse 2 angesteuerte, in einer Z- Achsrichtung verfahrbare Anschlagschlitten 25 gebildet ist.Along a rear side 21 of the table beam 8 and thus within the machine frame 5 and between the side uprights 7 along a linear guide assembly 22 is a stop device 23, which is preferably controlled by two in the guide assembly 22 independently and via a control and monitoring device 24 of the bending press 2 formed in a Z-axis movable stop slide 25 is formed.

Der Anschlagschlitten 25 lagert in einer linearen Führungsanordnung einen angetriebenen und in zur Verstellrichtung des Anschlagschlittens 25 senkrecht verlaufenden Richtung - gemäß Doppelpfeil 26 - in einer R- Achsrichtung - verstellbaren Fingerträger 27 mit einem darauf angeordneten Anschlagfinger 28, der in einer Führungsanordnung des Fingerträgers 27, in zur Verstellrichtung des Fingerträgers 27 senkrecht verlaufenden Richtung - gemäß Doppelpfeil 29 - in einer X-Achsrichtung motorisch verstellbar ist.The stop slide 25 supports in a linear guide arrangement a driven and in the direction of adjustment of the stop slide 25 perpendicular direction - according to double arrow 26 - in an R- axis direction - adjustable finger carrier 27 with a stop finger 28 arranged thereon, in a guide arrangement of the finger carrier 27, in to the adjustment direction of the finger carrier 27 perpendicular direction - according to double arrow 29 - is motor-adjustable in an X-axis direction.

Die Ansteuerung der Antriebe für den Anschlagschlitten 25 in der Z-Achsrichtung und den Fingerträger 27 in der R-Achsrichtung und den Anschlagfinger 28 in der X-Achsrichtung erfolgt zentral über Programmvorgaben bzw. von den in einem Datenspeicher 30 hinterlegten Daten.The actuation of the drives for the stop slide 25 in the Z-axis direction and the finger carrier 27 in the R-axis direction and the stop finger 28 in the X-axis direction takes place centrally via program instructions or from the data stored in a data memory 30.

Weiters ist es vorteilhaft, dass die Fertigungseinrichtung 1 im Greifbereich der Handhabungsvorrichtung 3 den Werkzeugspeicher 4 aufweist mit Speicherplätzen 31 für die Lagerhaltung der Biegewerkzeuge 13, wobei es vorteilhaft ist, den Werkzeugspeicher 4 mit dessen Speicherplätzen 31 für eine chaotische Ein- und Auslagerung der Biegewerkzeuge 13 in der Steuer- und Kontrollvorrichtung 24 zu verwalten.Furthermore, it is advantageous that the production device 1 in the gripping region of the handling device 3 has the tool storage 4 with storage locations 31 for the storage of the bending tools 13, wherein it is advantageous, the tool storage 4 with its memory locations 31 for a chaotic storage and retrieval of the bending tools 13th in the control and monitoring device 24 to manage.

Dazu sind die Speicherplätze 31 den Biegewerkzeugen 13, von denen jedes eine eindeutige, unverwechselbare Kennung aufweist, nach Verfügbarkeit frei zuordenbar. Die Kennung des Biegewerkzeuges 13 ist beispielsweise für ein automatisiertes Leseverfahren durch einen am Biegewerkzeug 13 angebrachten Barcode oder elektronischen Datenträger enthalten. Durch die Verwaltung in der Steuer- und Kontrollvorrichtung 24 und der Zuordnung der Speicherplätze 31 dem jeweiligen Biegewerkzeug 13 kann entsprechend den Planungsvorgaben eines Umformprozesses für einen Rüstvorgang der Biegepresse 2 auf das dazu vorgesehene Biegewerkzeug 13 im Werkzeugspeicher 4 mit der Handhabungsvorrichtung 3 zugegriffen und dieses dem Werkzeugspeicher 4 mittels der Greifeinrichtung 17 entnommen werden. Die weiteren Maßnahmen zur Durchführung eines Rüstvorganges, z.B. das Einsetzen des Biegegesenkes 14 in die Werkzeugaufnahme 11 des Tischbalkens 8 ist nun den Fig. 2 und 3 zu entnehmen und wird der Rüstvorgang nachfolgend an Hand dieser Figuren im Detail beschrieben.For this purpose, the memory locations 31 are freely assignable to the bending tools 13, each of which has a unique identifier. The identifier of the bending tool 13 is included, for example, for an automated reading process by a mounted on the bending tool 13 barcode or electronic data carrier. Due to the management in the control and monitoring device 24 and the assignment of the memory locations 31 the respective bending tool 13 can be accessed according to the planning specifications of a forming process for a set-up of the bending press 2 on the provided bending tool 13 in the tool memory 4 with the handling device 3 and this the tool memory 4 are removed by means of the gripping device 17. The further measures for carrying out a set-up operation, for example, the insertion of the bending die 14 in the tool holder 11 of the table beam 8 is now the FIGS. 2 and 3 and the setup process will be described in detail below with reference to these figures.

Es wird darauf verwiesen, dass der beschriebene Vorgang sinngemäß auch für das Einsetzen des Biegestempels 15 in die Werkzeugaufnahme 12 des Pressenbalkens 9 zutreffend ist, wobei dazu der verstellbare Pressenbalken in einer vordefinierten Lage, bevorzugt in der oberen Endlage mit dem Antriebsmittel positioniert ist.It should be noted that the procedure described is analogous to the insertion of the punch 15 in the tool holder 12 of the press bar 9 is correct, to which the adjustable press bar is positioned in a predefined position, preferably in the upper end position with the drive means.

Das von der Greifeinrichtung 17, z.B. einem Zangengreifer, erfasste Biegegesenk 14 wird mittels im Datenspeicher 30 der Steuer- und Kontrollvorrichtung 24 hinterlegter Bahnsteuerungsvorgaben der Handhabungsvorrichtung 3 nach X- und/oder Z- und/oder R- Koordinaten in eine, im Nahbereich einer geforderten Soll- Position 32 in einer Aufnahmenut 33 der Werkzeugaufnahme 11, in eine fiktive Referenzposition 34, entsprechend der in unterbrochenen Linien gezeigten Lage, gesteuert, die gewährleistet, dass es in Folge von Abweichungen einer tatsächlich eingenommenen IST- Position 35 des Biegegesenkes 14 --- wie den vollen Linien zu entnehmen, zu keiner Kollision zwischen dem Biegegesenk 14 und der Werkzeugaufnahme 11kommt. Bevorzugt wird die Referenzposition 34 eine Lage des Biegewerkzeuges 13 sein bei der sich das Biegewerkzeug 13 noch außerhalb der Aufnahmenut 33, also gering über bzw. unter den Werkzeugaufnahmen 11, 12 in der R- Achsrichtung befindet, jedoch die X- und Z- Achsrichtung entsprechend den vorgegebenen SOLL- Positionen vorgegeben werden, wodurch Nachpositionierwege auf Grund der sich einstellenden Abweichungen klein gehalten werden.The gripping device 17, e.g. a bending gripper 14 detected bending die 14 is by means of stored in the data memory 30 of the control and monitoring device 24 Bahnsteuerungsvorgaben the handling device 3 to X and / or Z and / or R coordinates in one, in the vicinity of a required target position 32 in a receiving groove 33 of the tool holder 11, in a fictitious reference position 34, according to the position shown in broken lines, controlled, which ensures that it as a result of deviations of an actual occupied actual position 35 of the bending die 14 --- as the full lines, to no collision between the bending die 14 and the tool holder 11 comes. Preferably, the reference position 34 will be a position of the bending tool 13 in which the bending tool 13 is still outside the receiving groove 33, ie slightly above or below the tool holders 11, 12 in the R- axis direction, but the X and Z axis direction accordingly the predetermined nominal positions are given, whereby Nachpositionierwege are kept small due to the settling deviations.

Bedingt werden diese Abweichungen von der eigenommenen IST- Position 35 zu der theoretisch angesteuerten Referenzposition 34 durch mechanische Einwirkungen auf die Handhabungsvorrichtung 3, wie unterschiedlichen Massen der Biegewerkzeuge 13 sowie durch Temperatureinflüsse, Toleranzen in den Führungen- und Antrieben der Handhabungsvorrichtung 3 etc.These deviations from the actual IS position 35 to the theoretically controlled reference position 34 are caused by mechanical effects on the handling device 3, such as different masses of the bending tools 13 and by temperature influences, tolerances in the guides and drives of the handling device 3, etc.

Ausgehend von den Positionsdaten der fiktiven Referenzposition 34 und den wie nachfolgend im Detail beschrieben ermittelten Positionsdaten der effektiven Ist- Position 35, und den geforderten und hinterlegten Daten der Soll- Position 32, in einem Bahnsteuerungsmodul 36 der Steuer- und Kontrolleinrichtung 24 wird eine Stellungskorrektur der Werkzeugposition von der IST- Position 35 auf die geforderte Soll- Position 32 über die Bahnsteuerung der Handhabungsvorrichtung 3 vorgenommen, wodurch das Einsetzen in die Werkzeugaufnahme 11 in der exakt geforderten Soll- Position 32 erfolgt und das Biegegesenk 14 in der Werkzeugaufnahme 11fixiert, das Biegegesenk 14 von der Greifeinrichtung frei gegeben wird und damit der Rüstvorgang abgeschlossen ist.Starting from the position data of the fictitious reference position 34 and the position data of the effective actual position 35, as determined in detail below, and the required and deposited data of the target position 32, in a path control module 36 of the control and monitoring device 24, a position correction of the tool position is made from the actual position 35 to the required target position 32 via the path control of the handling device 3, whereby the insertion into the Tool holder 11 takes place in the exact required target position 32 and the bending die 14 is fixed in the tool holder 11, the bending die 14 is released from the gripping device and thus the set-up process is completed.

Die Erfassung der Positionsdaten der IST- Position 35 des Biegegesenkes 14 nach den X- und/oder Z- und/oder R- Koordinaten erfolgt nach einer möglichen Ausführungsform mittels der Anschlagvorrichtung 23 durch einen Anschlagvorgang des Anschlagfingers 28 an Referenzflächen des Biegewerkzeuges 13, z.B. an drei jeweils rechtwinkelig zueinander ausgerichteten Werkzeugflächen 37, 38, 39 durch Verstellung des Anschlagschlittens 25 in der Z-Achsrichtung - gemäß Doppelpfeil 40, des Fingerträgers 27 in der R- Achsrichtung - gemäß Doppelpfeil 41 und des Anschlagfingers 28 in der X- Achsrichtung ---- gemäß Doppelpfeil 42.The detection of the position data of the actual position 35 of the bending die 14 according to the X and / or Z and / or R coordinates takes place according to a possible embodiment by means of the stop device 23 by a stop operation of the stop finger 28 on reference surfaces of the bending tool 13, e.g. at three mutually perpendicular tool surfaces 37, 38, 39 by adjusting the stop carriage 25 in the Z-axis direction - according to double arrow 40, the finger carrier 27 in the R- axis direction - according to double arrow 41 and the stop finger 28 in the X axis direction - - according to double arrow 42.

Die über eine Messmittel 43 aufweisende Messsensorik 44 der Anschlagvorrichtung 23, z.B. Annäherungssensoren des Anschlagfingers 28 oder beispielsweise Motorstrom- Messsensoren von Antriebsmitteln 45 für die Verstellung des Anschlagfingers 28, Fingerträgers 27 und Anschlagschlittens 25, ermittelten IST- Positionsdaten des Biegewerkzeuges werden in einer Vergleicherschaltung 46 der Steuer- und Kontrollvorrichtung 24 mit den im Datenspeicher 30 hinterlegten SOLL- Positionsdaten abgeglichen und aus den Abweichungen im Bahnsteuerungsmodul 36 Steuerungsparameter für die Bahnsteuerung der Handhabungsvorrichtung 3 generiert wonach die Positionierung des Biegewerkzeuges 13 in der vorgegebenen SOLL-Position 32 in der Werkzeugaufnahme 11 erfolgt.The measuring sensor 44, which has a measuring device 43, of the stop device 23, e.g. Proximity sensors of the stop finger 28 or, for example, motor current measuring sensors of drive means 45 for the adjustment of the stop finger 28, finger carrier 27 and stop carriage 25, determined actual position data of the bending tool are stored in a comparator circuit 46 of the control and monitoring device 24 with the stored in the data memory 30 Position data adjusted and generated from the deviations in the path control module 36 control parameters for the path control of the handling device 3, which then takes place the positioning of the bending tool 13 in the predetermined desired position 32 in the tool holder 11.

Erwähnt wird abschließend noch, dass das Verfahren nicht zwingend die Positionierung des Biegewerkzeuges 13 in den beschriebenen drei Achsrichtungen R-, X- und Z- Achsrichtung voraus setzt, vielmehr ist es selbstverständlich auch auf die Positionierung des Biegewerkzeuges 13 in nur einer oder zwei oder drei Achsrichtungen, wie beschrieben, anwendbar.Finally, it should be mentioned that the method does not necessarily presuppose the positioning of the bending tool 13 in the described three axial directions R, X and Z axis direction, but of course it is also on the positioning of the bending tool 13 in only one or two or three Axis directions, as described, applicable.

Es wird weiter darauf verwiesen, dass nach dem erfolgten Einsetzen des Biegewerkzeuges 13 in der Aufnahmenut 33 eine neuerliche Positionsfeststellung, insbesondere der Z- Achsrichtung auf möglich Abweichung, nach dem Spannen des Biegewerkzeuges in der Aufnahmenut mittels der Anschlagvorrichtung 23 bzw. der Messsensorik 44 vorgenommen wird und die ermittelten Positionsdaten mit den vorgegebenen SOLL- Positionsdaten verglichen werden. Falls dabei Abweichungen festgestellt werden können diese als Korrekturwerte an die Steuerund Kontrolleinrichtung 24 bzw. als solche im Datenspeicher als geänderte SOLL- Positionsdaten hinterlegt und für den Rüstvorgäng des weiteren Biegewerkzeuges 13, bzw. bei der Bahnsteuerung der Handhabungsvorrichtung 3 bei der Werkteilbeschickung für einen Umformvorgang berücksichtigt werden.It is further pointed out that after the successful insertion of the bending tool 13 in the receiving groove 33 a new position determination, in particular the Z axis direction on possible deviation, after the clamping of the bending tool in the receiving groove by means of the stop device 23 and the measuring sensor 44 is made and the determined position data are compared with the predetermined target position data. If deviations can be detected, these can be stored as correction values to the control and monitoring device 24 or as such in the data memory as changed desired position data and taken into account for the setup process of the further bending tool 13, or in the path control of the handling device 3 in the workpiece feed for a forming process become.

In der Fig. 4 ist eine mögliche Ausführung der Anschlagvorrichtung 23 mit dem Anschlagfinger 28 für die Erfassung der der Referenz- Positionsdaten des Biegewerkzeuges 13 dargestellt. Von dem für einen Rüstvorgang, von der nicht weiter gezeigten Handhabungsvorrichtung in der IST- Position 35, mit vorrichtungsbedingten Abweichungen von einer angesteuerten Referenzposition, gehaltene Biegewerkzeug 13, werden nach diesem Ausführungsbeispiel die X-und Z- Positionsdaten mittels der Messsensorik 44 und den im Anschlagfinger 28 in zueinander rechtwinkelig verlaufenden Anlageflächen 47, 48 integriert angerordneten Messmitteln 43, durch Anstellbewegungen des Anschlagfingers 28 an rechtwinkelig zueinander ausgerichteten Werkzeug- Referenzflächen 49, z.B. einer Stirnfläche 50 und einer Seitenfläche 51-gemäß den Doppelpfeilen 29, 40 - ermittelt.In the Fig. 4 a possible embodiment of the stop device 23 with the stop finger 28 for the detection of the reference position data of the bending tool 13 is shown. From the for a set-up, of the not further shown handling device in the ACTUAL position 35, with device-related deviations from a controlled reference position, held bending tool 13, according to this embodiment, the X and Z position data by means of the measuring sensor 44 and the stop finger 28 in mutually perpendicularly extending contact surfaces 47, 48 integrated ordered measuring means 43, by adjusting movements of the stop finger 28 at right angles aligned tool reference surfaces 49, eg an end face 50 and a side surface 51-according to the double arrows 29, 40 - determined.

Die Messmitteln 44 bilden nach dieser Ausführung beispielsweise Piezo- Elemente, Näherungssensoren etc., deren Signale an die Messsensorik 44 übermittelt werden. Über ein NC-Steuer- und Messsystem 52 der Anschlagvorrichtung 23 erfolgt die Auswertung der tatsächlich in der IST. Position vom Biegewerkzeug 13 eingenommen X- und Z- Positionsdaten von denen ausgehend eine Positionskorrektur auf die geforderte Soll- Position des Biegewerkzeuges 13 zum Einsetzen in die nicht weiter dargestellte Werkzeugaufnahme vorgenommen wird.The measuring means 44 form according to this embodiment, for example, piezo elements, proximity sensors, etc., whose signals are transmitted to the measuring sensor 44. Via an NC control and measuring system 52 of the stop device 23, the evaluation actually takes place in the IST. Position taken by the bending tool 13 X and Z position data from which starting a position correction is made to the required target position of the bending tool 13 for insertion into the tool holder not shown.

Wie der Fig. 4 weiter zu entnehmen ist nach diesem Ausführungsbeispiel am Biegewerkzeug eine Kennzeichnung 53, z.B. eine Strichcode 54 angebracht und weist der Anschlagfinger beispielsweise eine Kamera 55 für eine Werkzeugkontrolle auf wodurch ein fehlerhafter Rüstvorgang mit einem für einen vorgesehenen Umformvorgang nicht geeigneten Biegewerkzeug 13 vermieden wird.Again Fig. 4 Furthermore, according to this exemplary embodiment, a marking 53, for example a bar code 54, is attached to the bending tool and the stop finger has, for example, a camera 55 for tool control, thereby avoiding a faulty setting-up operation with a bending tool 13 which is not suitable for an intended forming operation.

Auch für die Verwaltung des Werkzeugspeichers und der Werkzeugentnahme bzw. Einlagerung der Werkzeuge in den Werkzeugspeicher mittels der Handhabungsvorrichtung ist der Einsatz derartiger Kommunikationsmittel möglich.Also for the management of the tool storage and tool removal or storage of the tools in the tool storage by means of the handling device, the use of such communication means is possible.

Wie weiter der Fig. 4 ebenfalls zu entnehmen, ist es beispielsweise möglich die IST- Position des Biegewerkzeuges 13 in der R- Achsrichtung - gemäß Doppelpfeil 56 - zu erfassen. Dazu ist beispielsweise ein weiteres Messmittel 43 auf einer Oberseite 57 und/oder Unterseite 58 des Anschlagfingers 28 angeordnet. In einem weiteren Messvorgang wird damit die Position des Biegewerkzeuges 13 durch einen Anstellvorgang des Anschlagfingers 28 an einer zu den Ebenen der Stirnfläche 50 und der Seitenfläche 51 senkrecht erstreckende Ebene, z.B. an einer Unterseite 59 des Biegewerkzeuges 13, ermittelt.How further the Fig. 4 can also be seen, it is for example possible to detect the actual position of the bending tool 13 in the R- axis direction - according to double arrow 56 -. For this purpose, for example, a further measuring means 43 on an upper side 57 and / or bottom 58 of the stop finger 28 is arranged. In a further measuring operation, the position of the bending tool 13 is thus determined by a positioning process of the stop finger 28 at a plane perpendicular to the planes of the end face 50 and the side face 51, eg on a lower side 59 of the bending tool 13.

Eine weitere Möglichkeit der Positionsermittlung des Biegewerkzeuges 13, in einer, zwei oder drei Raumrichtungen durch einen Anstellvorgang des Anschlagfinger 28 an den Referenzflächen des Biegewerkzeuges 13, besteht in der Messung der Motorstromaufnahme an jedem für die Verstellung des Anschlagfingers 28 in den entsprechenden Raumrichtungen maßgebenden Antriebsmittel 45 der Anschlagvorrichtung 23. Dazu ist dem Antriebsmittel 45 ein Strommesssensor 60 zugeordnet der bei einer Stromerhöhung, bedingt durch einen Anschlagvorgang des Anschlagfingers 28 am Biegewerkzeug 13, ein Positionssignal an die Messsensorik 44 bzw. dem NC- Steuer- und Messsystem 52 abgibt und sich daraus die jeweilige Koordinate als IST- Position ableitbar ist.Another way of determining the position of the bending tool 13, in one, two or three spatial directions by a stopping operation of the stop finger 28 on the reference surfaces of the bending tool 13, consists in measuring the motor current consumption at each authorizing the adjustment of the stop finger 28 in the corresponding spatial directions drive means 45th the stop means 23. For this purpose, the drive means 45, a current measuring sensor 60 is assigned to a current increase due to a stop operation of the stop finger 28 on the bending tool 13, a position signal to the measuring sensor 44 and the NC control and measuring system 52 outputs and from the respective coordinate can be derived as an actual position.

In der vorhergehenden Beschreibung ist zur Ermittlung der IST- Positiondaten des Biegewerkzeuges 13 auf die Verstellung der Anschlagvorrichtung 23 bzw. des Anschlagfingers 28 relativ zu dem von der Greifvorrichtung in der IST- Position bereit gehaltenen Biegewerkzeug 13 eingegangen worden.In the foregoing description, to determine the actual position data of the bending tool 13, reference has been made to the adjustment of the stop device 23 and the stop finger 28 relative to the bending tool 13 held ready by the gripping device in the actual position.

Es ist jedoch weiter festzuhalten, dass zur Erzielung der exakten SOLL- Position, für das Einsetzen des Biegewerkzeuges 13 in der Werkzeugaufnahme, es auch möglich ist zumindest einen Anschlagfinger 28 der Anschlagvorrichtung 23 in einer der Referenzposition des Biegewerkzeuges 13 entsprechende Position zu positionieren und das Biegewerkzeug 13 mit der Handhabungsvorrichtung 3 zur Anlage an den Anschlagfinger 28 in der X- Achsrichtung und/oder Z- Achsrichtung und/oder R- Achsrichtung zu verstellen und damit IST- Positionsdaten, als von anlagenbedingten Abweichungen bereinigte Ausgangsdaten, für den Transfer des Biegewerkzeuges 13 in die vorgegebene SOLL- Position in der Werkzeugaufnahme durch die Handhabungsvorrichtung, festzulegen.However, it should be further noted that in order to achieve the exact TARGET position for insertion of the bending tool 13 in the tool holder, it is also possible to position at least one stop finger 28 of the stop device 23 in a position corresponding to the reference position of the bending tool 13 and the bending tool 13 with the handling device 3 to bear against the stop finger 28 in the X-axis direction and / or Z-axis direction and / or R-axis direction and thus actual position data, as adjusted by plant-related deviations output data, for the transfer of the bending tool 13 in the predetermined desired position in the tool holder by the handling device set.
