Description

Die Erfindung bezieht sich auf eine Vorschubvorrichtung zum Eingeben und Vorschieben von Tafeln in eine Werkzeugmaschine, mit einem Vorschubschlitten, der eine Greifvorrichtung zum Erfassen einer Kante der Tafeln aufweist und der entlang einer ersten Führung mittels eines ersten Vorschubantriebs verstellbar ist, einer zweiten Führung, deren Achse orthogonal zur Achse der ersten Führung verläuft und entlang der die erste Führung mittels eines zweiten Vorschubantriebs verstellbar ist, einer Positionierstation, in der aufeinanderfolgend die Tafeln bezüglich der orthogonalen Achsen positioniert werden, eine Übergabestrecke zwischen Werkzeugmaschine und Positionierstation und einer automatischen Steuervorrichtung, die die Arbeitshübe der Werkzeugmaschine erfasst und die Vorschubantriebe synchron zu den Arbeitshüben ansteuert.The invention relates to a feed device for inserting and feeding sheets into a machine tool, with a feed slide, which has a gripping device for gripping an edge of the sheets and which is adjustable along a first guide by means of a first feed drive, a second guide, the axis of which runs orthogonal to the axis of the first guide and along which the first guide can be adjusted by means of a second feed drive, a positioning station in which the panels are successively positioned with respect to the orthogonal axes, a transfer path between the machine tool and the positioning station and an automatic control device which controls the working strokes Machine tool detected and the feed drives controlled synchronously with the working strokes.

Eine derartige Vorrichtung ist bekannt (US-A-4382394 oder DE-U-8318201). Sie dient dazu, Tafeln, zum Beispiel aus Aluminium, positioniert einer Presse zuzuführen, die eine vorgegebene Anzahl von Rohlingen aus der Tafel ausstanzt. Zu diesem Zweck wird die Tafel in einer Vorschubvorrichtung eingespannt und zwischen den Stanzwerkzeugen bewegt. Die Bewegung erfolgt normalerweise entlang zweier orthogonaler Achsen, da zwecks günstiger Materialausnutzung eine versetzte Teilung gewählt wird.Such a device is known (US-A-4382394 or DE-U-8318201). It is used to position sheets, for example made of aluminum, in a positioned position in a press that punches out a predetermined number of blanks from the sheet. For this purpose, the board is clamped in a feed device and moved between the punching tools. The movement normally takes place along two orthogonal axes, since an offset division is selected for the purpose of favorable material utilization.

Bei der bekannten Vorrichtung ist der Vorschubschlitten mit Hilfe eines Spindelantriebs entlang der ersten Führung verfahrbar. Die erste Führung ist mit Hilfe eines weiteren Spindelantriebs entlang der zweiten Führung verfahrbar. Der Vorschubschlitten weist zwei Greifzangen auf, welche die Tafel an der hinteren Kante erfassen und schrittweise in der Werkzeugmaschine vorschieben. Dieser Vorschub -ist mit der Bewegung der Werkzeugmaschine, beispielsweise einer Stanze, gekoppelt, derart, dass die Verstellung in einer Zeit erfolgt, in der während des Rückhubs und des Arbeitshubs das Werkzeug sich ausserhalb der Arbeitsebene befindet. Nach Beendigung eines Arbeitszyklus für eine Tafel fährt der Ladeschlitten in eine Ausgangsposition zurück, in der er die nächste Blechtafel erfasst. Diese Blechtafel wurde von einem Ladeschlitten aus einer Positionierstation lagerichtig in die Ladeposition vorgeschoben. In der bekannten Vorrichtung enthält die Ladevorrichtung einen Ladeschlitten, der Greifmittel zum Ergreifen der Blechplatte aufweist, wobei sich der Ladeschlitten unter der Vorschubvorrichtung hindurchbewegt, um die Blechtafel in die Ladeposition zu bringen. Die Ladevorrichtung ist so ausgeführt, dass der Ladeschlitten stets an der gleichen Stelle die Ladeposition erreicht, unabhängig von der Grösse der Blechtafel und dem Stanzbild, so dass auch die Blechtafel eine vorgegebene Ausgangsposition erhält.In the known device, the feed carriage can be moved along the first guide with the aid of a spindle drive. The first guide can be moved along the second guide with the aid of a further spindle drive. The feed carriage has two gripping tongs that grasp the sheet at the rear edge and advance it step by step in the machine tool. This feed is coupled with the movement of the machine tool, for example a punch, in such a way that the adjustment takes place in a time in which the tool is outside the working plane during the return stroke and the working stroke. After a work cycle for a sheet has ended, the loading carriage returns to a starting position in which it grips the next sheet of metal. This sheet of metal was pushed in the correct position into the loading position by a loading carriage from a positioning station. In the known device, the loading device contains a loading carriage which has gripping means for gripping the sheet metal plate, the loading carriage moving under the feed device in order to bring the sheet metal plate into the loading position. The loading device is designed in such a way that the loading carriage always reaches the loading position at the same point, regardless of the size of the metal sheet and the die-cut pattern, so that the metal sheet also has a predetermined starting position.

Aufgrund der beschriebenen Übergabe der einzelnen Tafeln in die Vorschubvorrichtung verstreicht zwischen dem letzten Arbeitshub für eine Blechtafel und dem ersten Arbeitshub für die nächstfolgende Blechtafel eine gewisse Zeit, in der die Werkzeugmaschine mehrere Leerhübe ausführt. Derartige Leerhübe sind jedoch unerwünscht, da sie die Produktionsleistung mindern.Due to the described transfer of the individual sheets into the feed device, a certain time elapses between the last working stroke for a metal sheet and the first working stroke for the next sheet metal sheet, in which the machine tool carries out several empty strokes. Such empty strokes are undesirable, however, because they reduce production output.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorschubvorrichtung zum Eingeben und Vorschieben von Tafeln in eine Werkzeugmaschine zu schaffen, in der die Tafeln ohne Leerzeiten der Werkzeugmaschine bearbeitet werden können.The invention is therefore based on the object of providing a feed device for inputting and advancing sheets into a machine tool, in which the sheets can be processed without the machine tool being idle.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass zwei parallele erste Führungen sich zwischen der Positionierstation und der Werkzeugmaschine erstrecken und jeweils einen Vorschubschlitten mit Greifvorrichtung führen und jeweils einen ersten Vorschubantrieb aufweisen, dass beide ersten Führungen von der zweiten Führung geführt werden und durch je einen eigenen zweiten Vorschubantrieb verstellbar sind, und dass die Steuervorrichtung die zu den Vorschubschlitten gehörenden Vorschubantriebe so steuert, dass die Tafel in die erste Bearbeitungsposition in der Werkzeugmaschine vorgeschoben ist, bevor die Werkzeugmaschine nach dem letzten Arbeitshub für die voraufgegangene Tafel einen weiteren Arbeitshub ausführt.This object is achieved according to the invention in that two parallel first guides extend between the positioning station and the machine tool and each guide a feed slide with gripping device and each have a first feed drive in that both first guides are guided by the second guide and by a separate second each Feed drive are adjustable, and that the control device controls the feed drives belonging to the feed carriages in such a way that the board is advanced into the first machining position in the machine tool before the machine tool carries out a further work stroke for the previous board after the last working stroke.

Bei der erfindungsgemässen Vorrichtung ist eine Ladevorrichtung nicht erforderlich. Während ein erster Vorschubschlitten eine Tafel in der Werkzeugmaschine vorschiebt, kann der zweite Ladeschlitten die nächste Tafel aus der Positionierstation holen, um diese in der Werkzeugmaschine vorzuschieben, sobald die voraufgegangene Tafel fertig bearbeitet ist, zum Beispiel alle Rohlinge ausgestanzt worden sind. Da die Vorschubantriebe für jeweils einen Schlitten naturgemäss mit der Bewegung der Werkzeugmaschine synchronisiert sein müssen, ist es auch ohne weiteres möglich, etwa mit Hilfe geeigneter numerischer Steuerungen, die nachfolgende Blechtafel in die erste Bearbeitungsposition zu bringen, nachdem der letzte Arbeitshub bei der vorangegangenen Tafel ausgeführt wurde. Da die Hubfrequenz konstant und bekannt ist, kann der Ladeschlitten so gesteuert werden, dass er die Tafel aus der Positionierstation zeitlich richtig in die erste Bearbeitungsposition fördert, nachdem der letzte Arbeitshub beendet wurde und bevor der neue Arbeitshub ausgeführt wird. Nach einer Ausgestaltung der Erfindung hierzu ist vorgesehen, dass die Steuervorrichtung so ausgelegt ist, dass der Vorschubschlitten die Tafel in der Übergabestrecke synchron der Vorschubbewegung der voraufgehenden Tafel in dem anderen Vorschubschlitten nachfährt. Dies kann in der Weise durchgeführt werden, dass die in Wartestellung befindliche Tafel sehr nahe an die bearbeitete Tafel herangefahren wird, beispielsweise in einem Abstand von 1 mm und die in Bereitstellung befindliche Tafel alle Bewegungen der Tafel in der Werkzeugmaschine nachfährt, so dass die Ausrichtung und der Abstand der Tafeln zueinander stets beibehalten bleiben.A charging device is not required in the device according to the invention. While a first feed slide feeds a sheet in the machine tool, the second loading slide can fetch the next sheet from the positioning station in order to feed it into the machine tool as soon as the previous sheet is finished, for example, all blanks have been punched out. Since the feed drives for each slide naturally have to be synchronized with the movement of the machine tool, it is also easily possible, for example with the aid of suitable numerical controls, to bring the subsequent sheet metal into the first machining position after the last working stroke has been carried out on the previous sheet has been. Since the stroke frequency is constant and known, the loading carriage can be controlled in such a way that it correctly feeds the sheet from the positioning station into the first processing position after the last working stroke has ended and before the new working stroke is carried out. According to one embodiment of the invention, it is provided that the control device is designed in such a way that the feed carriage follows the board in the transfer section in synchronism with the feed movement of the preceding board in the other feed carriage. This can be done in such a way that the waiting table is moved very close to the processed table, for example at a distance of 1 mm, and the waiting table tracks all movements of the table in the machine tool, so that the alignment and the distance between the panels is always maintained.

Gegenüber der bekannten Vorschubvorrichtung weist die Erfindung vier Achsen auf. Eine besondere Übergabevorrichtung, etwa in Form eines Ladeschlittens oder dergleichen, entfällt. Der neuartige Aufbau der erfindungsgemässen Vorrichtung ermöglicht gegenüber der bekannten Vorrichtung den Wegfall jeglicher Wechselzeiten, d. h. jeder Hub der Werkzeugmaschine ist ein Arbeitshub. Gegenüber den bekannten Vorrichtungen wird dadurch eine Produktionssteigerung bis zu 30% erzielt.Compared to the known feed device, the invention has four axes. A special their transfer device, for example in the form of a loading carriage or the like, is omitted. Compared to the known device, the novel construction of the device according to the invention makes it possible to eliminate any change times, ie each stroke of the machine tool is a working stroke. Compared to the known devices, an increase in production of up to 30% is achieved.

Damit die Ladeschlitten bei der erfindungsgemässen Vorrichtung sich nicht gegenseitig stören, verlaufen die parallelen ersten Führungen in einer Richtung, die mit der Richtung zusammenfällt, in der die Tafeln aus der Positionierstation in Richtung Werkzeugmaschine bewegt werden. Nach dem Beenden einer Bearbeitung einer Tafel in der Werkzeugmaschine kann die zugehörige erste Führung des Werkzeugschlittens diesen aus dem Kollisionsbereich mit der vom anderen Ladeschlitten herangeführten Tafel herausfahren, wenn er zur Positionierstation bewegt wird. Eine relative Höhenverstellung, wie sie bei der bekannten Vorrichtung bezüglich des Vorschub- und des Ladeschlittens erforderlich ist, entfällt.So that the loading slides in the device according to the invention do not interfere with one another, the parallel first guides run in a direction that coincides with the direction in which the plates are moved out of the positioning station in the direction of the machine tool. After a processing of a sheet in the machine tool has ended, the associated first guide of the tool slide can move it out of the collision area with the sheet brought up by the other loading slide when it is moved to the positioning station. A relative height adjustment, as is required in the known device with regard to the feed and loading carriage, is not required.

Die Erfindung wird nachfolgend anhand einer Zeichnung näher erläutert.The invention is explained in more detail with reference to a drawing.

Die einzige Figur zeigt eine Draufsicht auf die stark schematisierte Vorschubvorrichtung nach einem bevorzugten Ausführungsbeispiel der Erfindung.The single figure shows a plan view of the highly schematic feed device according to a preferred embodiment of the invention.

Eine Stanze 10, deren Oberteil aus Darstellungsgründen fortgelassen wurde, besitzt drei Stanzwerkzeuge, die durch dick ausgezogene Linien 11 angedeutet sind. Sie dienen zum Ausstanzen von kreisförmigen Rohlingen 12 aus einer strichpunktiert gezeichneten Blechtafel 13. Die Stanze 10 ist von bekannter Bauart und soll nicht im einzelnen erläutert werden. Auch die notwendige Auswerfvorrichtung ist nicht dargestellt.A punch 10, the upper part of which has been left out for reasons of illustration, has three punching tools, which are indicated by thick solid lines 11. They are used for punching out circular blanks 12 from a metal sheet 13 shown in dot-dash lines. The punch 10 is of a known type and is not to be explained in detail. The necessary ejection device is also not shown.

In einer Einschubvorrichtung 14 befindet sich ein Blechstapel, der mit Hilfe einer nicht dargestellten Hubvorrichtung schrittweise angehoben wird. Die jeweils oberste Blechtafel wird mit Hilfe mehrerer vertikal verstellbarer Saugköpfe in den Spalt zwischen Einführwalzen einer Beschichtungsvorrichtung 15 eingeschoben. Die Blechtafel fällt von oben auf einen nicht dargestellten Maschinentisch. Dem Maschinentisch sind zwei erste Anschläge 16, 17 und ein zweiter Anschlag 18 zugeordnet. Ein nicht gezeigter Positionierantrieb legt die Tafel in der Positionierstation gegen die Anschläge 16 bis 18, um sie bezüglich vorgegebener X- und Y-Koordinaten in eine vorgegebene Lage zu bringen. Eine derartige Vorrichtung ist zum Beispiel aus der US-A-4382395 bekannt.In a slide-in device 14 there is a stack of sheets which is raised step by step with the aid of a lifting device, not shown. The topmost sheet of metal is inserted into the gap between the insertion rollers of a coating device 15 with the aid of a plurality of vertically adjustable suction heads. The sheet of metal falls from above onto a machine table, not shown. Two first stops 16, 17 and a second stop 18 are assigned to the machine table. A positioning drive, not shown, places the board in the positioning station against the stops 16 to 18 in order to bring it into a predetermined position with respect to predetermined X and Y coordinates. Such a device is known for example from US-A-4382395.

In Y-Richtung erstrecken sich zwei relativ lange Führungen 19, 20, die etwa in der Mitte nicht gezeigte Antriebe aufweisen. Die Führungen lagern Vorschubschlitten 23 bzw. 24, die jeweils zwei Greifzangen 25,26 aufweisen. Die Führungen erstrecken sich von der Positionierstation bis zur Stanze 10 und etwas darüber hinaus, wie aus der Zeichnung ersichtlich wird.Two relatively long guides 19, 20, which have drives not shown in the middle, extend in the Y direction. The guides support feed carriages 23 and 24, which each have two gripping tongs 25, 26. The guides extend from the positioning station to the punch 10 and somewhat beyond, as can be seen from the drawing.

Eine zweite Führung 27 ist stationär angeordnet und trägt an den gegenüberliegenden Enden Vorschubantriebe 28, 29. Die Vorschubantriebe 28, 29, zum Beispiel Scheibenläufermotoren, treiben Verstellspindeln 30, 31 an. Die zweite Führung 27 lagert die Führungen 19, 20 annähernd mittig zur Verstellung in X-Richtung. Zur Verstellung der Vorschubschlitten 23, 24 sind verschiedene Antriebe denkbar, beispielsweise über Spindeln, Seilzüge, Riemen und dergleichen.A second guide 27 is arranged in a stationary manner and carries feed drives 28, 29 at the opposite ends. The feed drives 28, 29, for example disc-type motors, drive adjusting spindles 30, 31. The second guide 27 supports the guides 19, 20 approximately centrally for adjustment in the X direction. Various drives are conceivable for adjusting the feed slides 23, 24, for example via spindles, cable pulls, belts and the like.

Eine nicht gezeigte, vorzugsweise numerische Steuerung steuert die einzelnen Antriebe und Betriebsabläufe auf vollständig automatische Weise.A preferably numerical control, not shown, controls the individual drives and operating sequences in a completely automatic manner.

Die beschriebene Vorrichtung arbeitet wie folgt.The device described works as follows.

Sobald die Positionierstation frei ist, wird eine Blechtafel von der Einschubvorrichtung auf den Arbeitstisch gefördert, und die Blechtafel wird mit Hilfe des Positionierantriebs und der Anschläge 16 bis 18 in eine vorgegebene Ausgangslage gebracht. Die Greifzangen 25, 26 des Ladeschlittens 24 haben eine Blechtafel 13 an der linken Kante (in Y-Richtung gesehen) erfasst und bewegen die Tafel in einzelnen Schritten entlang der X- und Y-Achse durch die Stanze 10, die nacheinander Rohlinge 12 aus der Tafel 13 ausstanzt. Während dieses Arbeitsvorgangs war der Schlitten 23 bereits in die Positionierstation gefahren, um eine positionierte Tafel mit seinen Zangen 25, 26 an der rechten Kante zu ergreifen. Es versteht sich, dass während der Aufnahme der Tafel 13 in der Positionierstation durch die Zangen 25, 26 deren Lage bzw. die Lage des Schlittens 23 definiert sein muss. Der Schlitten 23 führt die aufgenommene Tafel nahe an die bearbeitete Tafel heran (mittlere der drei strichpunktierten Tafeln in der Zeichnung). Gleichzeitig werden die Vorschubantriebe so gesteuert, dass die in der Bereitschaftsstellung befindliche Tafel synchron die Bewegungen der vordersten Tafel 13 in-der Stanze 10 nachvollzieht. In dem Augenblick, in dem die Stanze 10 den letzten Arbeitshub ausgeführt und die Werkzeuge im Rückhub begriffen sind, fährt der Vorschubschlitten 23 die aufgenommene Tafel in die erste Bearbeitungsposition. Gleichzeitig fährt der Antrieb 29 den Vorschubschlitten 24 mitsamt der abgearbeiteten Tafel aus dem Werkzeugbereich heraus. Der Vorschubschlitten 24 fährt anschliessend mit zurückgezogener zweiter Führung zurück, um mit seinen Zangen 25, 26 nicht gegen die neue Tafel in der Positionierstation zu stossen; die Aufnahme der neuen Tafel ist strichpunktiert angedeutet.As soon as the positioning station is free, a sheet of metal is conveyed from the insertion device onto the work table, and the sheet of metal is brought into a predetermined starting position with the aid of the positioning drive and the stops 16 to 18. The gripping tongs 25, 26 of the loading carriage 24 have gripped a metal sheet 13 on the left edge (seen in the Y direction) and move the sheet in individual steps along the X and Y axes through the punch 10, which successively remove blanks 12 from the Cut out plate 13. During this operation, the carriage 23 had already moved into the positioning station in order to grip a positioned panel with its pliers 25, 26 on the right edge. It goes without saying that while the plate 13 is being received in the positioning station, the position or the position of the slide 23 must be defined by the tongs 25, 26. The carriage 23 brings the picked-up sheet close to the processed sheet (middle of the three dash-dotted sheets in the drawing). At the same time, the feed drives are controlled in such a way that the board in the ready position synchronously tracks the movements of the foremost board 13 in the punch 10. At the moment when the punch 10 executes the last working stroke and the tools are in the return stroke, the feed carriage 23 moves the picked sheet into the first processing position. At the same time, the drive 29 moves the feed slide 24 together with the finished sheet out of the tool area. The feed carriage 24 then moves back with the second guide withdrawn so that its tongs 25, 26 do not hit the new board in the positioning station; the recording of the new board is indicated by dash-dotted lines.

Damit eine Synchronisation des Vorschubs der Tafeln mit Hilfe der Vorschubschlitten 23, 24 mit der Bewegung der Stanze 10 erfolgen kann, muss ein Geber vorgesehen sein, um deren Bewegungsablauf zu ermitteln. Dies kann beispielsweise durch Erfassung der Kurbelwellendrehung der Stanze 10 erfolgen (Z-Achse). Aus der Kurbelwellendrehung wird der Vorschubtakt der Tafel 13 in der Stanze 10 abgeleitet. Sie bestimmt auch, zu welchem Zeitpunkt die neue Tafel in der ersten Bearbeitungsposition sein muss, damit ohne Leerhub das Ausstanzen der neuen Tafel beginnen kann. Da die Blechtafeln in der Positionierstation genau positioniert und in vorgegebener Lage von den Vorschubschlitten 23 oder 24 aufgenommen werden, stehen auch die zurückgelegten Wege von der Positionierstation bis zur ersten Bearbeitungsposition in der Stanze fest. Die numerische Steuerung kann daher jede Vorschubbewegung von der Positionierstation bis zur Stanze kontrollieren.So that the feed of the sheets can be synchronized with the movement of the punch 10 with the aid of the feed slides 23, 24, a transmitter must be provided in order to determine their movement sequence. This can be done, for example, by detecting the crankshaft rotation of the punch 10 (Z axis). The feed stroke of the table 13 in the punch 10 is derived from the crankshaft rotation. It also determines the time at which the new sheet must be in the first processing position so that the new sheet can be punched out without an idle stroke. Since the metal sheets are precisely positioned in the positioning station and received in a predetermined position by the feed slides 23 or 24 the distances traveled from the positioning station to the first processing position in the punch are also fixed. The numerical control can therefore control every feed movement from the positioning station to the punch.

Alternativ zum beschriebenen synchronisierten Nachfahren der neuen Platte, kann die neue Tafel auch zunächst in der Positionierstation verbleiben, und der zugeordnete Vorschubschlitten so gesteuert werden, dass der richtige Startzeitpunkt von der Positionierstation aus errechnet wird und die Tafel direkt in die erste Bearbeitungsposition gefahren wird.As an alternative to the described synchronized tracing of the new plate, the new plate can initially remain in the positioning station, and the assigned feed slide can be controlled so that the correct starting time is calculated from the positioning station and the plate is moved directly to the first processing position.

Claims (2)

1. Feeding device for loading and transferring panels (13) into a machine tool (10) including a feeding slide (23, 24) comprising a gripping device (25, 26) for gripping one edge of the panels (13) and being displaceable along a first guide (19, 20) by means of a first feeding drive, a second guide (27) the axis of which extending orthogonally to the axis of the first guide (19, 20) and along which the first guide (19, 20) is displaceable by means of a second feeding drive (28, 29), a positioning station wherein the panels (13) are positioned one- by-one with respect to the orthogonal axes, a transfer line between the machine tool and the positioning station, and an automatic control device detecting the working motions of the machine tool (10) and driving the feeding drives synchronously with the motions of the machine tool, characterized in that two parallel first guides (19, 20) extend between the positioning station and the machine tool (10) and guide a feeding slide (23, 24) each including a gripping device (25, 26) and comprise a first feeding drive each, that both first guides (19, 20) are guided by the second guide (27) and are displaceable each by an associated second feeding drive (28, 29), and that the control device controls the feeding drives associated with a feeding slide (23, 24) such, that the panel is transferred into the first working position of the machine tool (10) before the machine tool (10) effects a further working stroke after the last working stroke for the preceding panel.
2. The device according to claim 1, characterized in that the control device is designed such that in the transfer line the one feeding slide (23, 24) transfers the panels (13) synchronously with the feeding motion of the preceding panel (13) in the other feeding slide (23, 24).
