Description

Die vorliegende Erfindung betrifft ein Verfahren zum Zuführen und Vorschieben eines Streifens in ein bzw. durch ein Umformwerkzeug gemäss Oberbegriff des Anspruchs 1, und einen Streifenanleger zur Durchführung dieses Verfahrens.The present invention relates to a method for feeding and advancing a strip into and through a Forming tool according to the preamble of claim 1, and a strip feeder for performing this procedure.

Verfahren bzw. Streifenanleger dieser Art sind z. B. aus DE-U-8,220,431 (nächstliegender Stand der Technik) oder EP-A-0,409,151 bekannt. In beiden Fällen ist ein umlaufendes Förderorgan, also ein Riemen bzw. eine Walze vorgesehen, und diese Förderorgane müssen, sofern sie mit einem Mitnahmefinger versehen sind, nach dem schrittweisen Vorschieben eines Streifens den vollen Weg zurücklaufen, um einen nächsten Streifen zu erfassen. Sind Förderwalzen vorgesehen, ist es kaum möglich, in allen Fällen Streifen oder dergleichen Teile genau zu bewegen, und das hintere Ende derselben genügend nahe an ein Werkzeug heranzufördern.Processes and strip feeders of this type are e.g. B. from DE-U-8,220,431 (closest state of the art) or EP-A-0,409,151. In both Felling is a rotating conveyor, that is a belt or a roller, and these conveying elements must if they are provided with a driving finger, after the gradually advance a strip the full way run back to capture another streak. are Conveyor rollers provided, it is hardly possible in all Cases to move strips or the like parts accurately, and the rear end of the same sufficiently close to one Convey tool.

Gemäss DE-U-8,220,431 sind daher ausser einem Riemenförderer Schubstangen vorgesehen, welche dem eigentlichen Einführen des Streifens in das Umformwerkzeug dienen. Ausser diesen zusätzlichen Förderstangen sind ein- und ausdrückbarer Kupplungen erforderlich, um die Fördermittel wahlweise wirksam zu machen.According to DE-U-8,220,431 are therefore one Belt conveyor push rods provided which the actually inserting the strip into the forming tool to serve. In addition to these additional conveyor rods are one and expressible clutches required to Make funding effective.

Die US-A-4,090,703 zeigt eine Vorrichtung zum Zuführen und Vorschieben von Streifen in ein bzw. durch ein Umformwerkzeug mit drei verschiedenen Fördereinheiten von welchen die eine Fingerstangen mit in gleichmässigen Abständen liegenden Fingern zum schrittweisen vorschieben eines Streifens aufweisten. Die Förderorgane werden mit einem einheitlichen, unverstellbaren Hub angetrieben. US-A-4,090,703 shows an apparatus for feeding and Feeding strips into and through a Forming tool with three different conveyor units from which the finger sticks with in uniform Spaced fingers to gradually advance of a strip. The funding bodies are with driven by a uniform, non-adjustable stroke.

Ziel vorliegender Erfindung ist es, die genannten, funktionellen Nachteile bei einfachem Aufbau zu vermeiden. Dieses Ziel wird gemäss dem Anspruch 1 bzw. 3 erreicht. Da die Fingerstange in Längsrichtung bzw. Bewegungsrichtung mehrere Finger aufweist, die vorzugsweise in unterschiedlichen Abständen voneinander liegen, bestehen weitgehende Freiheiten in der Programmgestaltung und es sind immer nur beschränkte, schnell ausführbare Schritte von beispielsweise höchstens 400 mm erforderlich.The aim of the present invention is to Avoid functional disadvantages with a simple structure. This goal is according to claim 1 or 3 reached. Since the finger bar in the longitudinal direction or Direction of movement has several fingers, preferably are at different distances from each other extensive freedom in programming and it are always limited, quickly executable steps of, for example, a maximum of 400 mm is required.

Die Erfindung wird nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.

The invention will now be explained in more detail with reference to an embodiment shown in the drawing.
Fig. 1
is a schematic side view of the strip feeder according to the invention and an associated forming tool,
Figs. 2-5
show different operating states when feeding and processing a strip and
Fig. 6
shows the different operating positions during a working cycle of the strip feeder.

Figur 1 zeigt ein Umformwerkzeug 1, beispielsweise zum Ausstanzen von Rondellen aus Streifen 2. Die Streifen 2 weisen die an sich übliche Form mit gewellten Seiten auf, aus welchen unter optimaler Ausnützung des Materials gemäss Fig. 2 z. B. zwei Reihen von in Längs- und Querrichtung versetzten Rondellen ausgestanzt werden können. Es kann aber natürlich auch eine andere Bearbeitung, beispielsweise eine Verformung des Materials, erfolgen. Der Streifenanleger weist eine Fingerstange 3 auf, die beim Ausführungsbeispiel mit fünf federnden Fingern oder Mitnehmern 4 - 8 besetzt ist. Diese Finger stehen im unbelasteten Zustand unter Federwirkung über die Fingerstange 3 vor, und können somit einen Streifen 2 an seiner hinteren Kante erfassen und mitnehmen, und die von einem Streifen bedeckten Finger werden in die Fingerstange 3 hineingedrückt. Die drei in Förderrichtung hintersten Finger 4 - 6 liegen in einem kleineren gegenseitigen Abstand als die vorderen Finger 6, 7 und 8. Der vorderste Finger 8 liegt am vorderen Ende der Fingerstange 3 und kann somit einen Streifen 2 gemäss Fig. 2 in die letzte Position zum Ausschneiden der letzten Rondelle bzw. zum Bearbeiten des letzten Teils in einem Streifen einschieben, ohne mit dem Umformwerkzeug in Kollision zu geraten. Das Restgitter des Streifens, aus dem alle Teile ausgestanzt sind, wird mittels eines Paares von Auszugswalzen 9 aus dem Umformwerkzeug abgezogen. Die Streifen 2 werden aus einem Magazin 10 mittels eines Vertikalstaplers 11 in bekannter Weise einzeln entnommen und auf eine nicht dargestellte Führungsbahn abgelegt, auf welcher sie durch die Finger der Fingerstange 3 erfasst und dem Umformwerkzeug 1 zugeführt werden können. Die Fingerstange 3 ist mit einem programmierbaren Linearantrieb 12 verbunden, der ein ganzes Programm von beliebigen Vorlauf- und Rücklaufhüben ausführen kann, wie in Fig. 1 durch verschieden lange Pfeile angedeutet ist.FIG. 1 shows a forming tool 1, for example for punching out of rondelles from strips 2. The strips 2 point the usual form with wavy sides on which with optimal use of the material according to FIG. 2 e.g. B. two rows of offset in the longitudinal and transverse directions Rondelles can be punched out. But of course it can another processing, for example a deformation of the material. The strip feeder has one Finger rod 3, which in the embodiment with five resilient fingers or carriers 4-8 is occupied. These fingers are spring loaded when unloaded over the finger bar 3 in front, and can thus one Grip strip 2 on its rear edge and take it with you, and the fingers covered by a strip are placed in the Finger rod 3 pushed in. The three in the conveying direction rearmost fingers 4 - 6 are in a smaller mutual Distance than the front fingers 6, 7 and 8. The foremost Finger 8 lies at the front end of finger bar 3 and can thus a strip 2 according to FIG. 2 in the last Position for cutting out the last roundel or for editing insert the last part into a strip, without colliding with the forming tool. The Remaining grid of the strip from which all parts are punched out are, by means of a pair of pull-out rollers 9 from the Forming tool removed. The strips 2 are made from one Magazine 10 by means of a vertical stacker 11 in a known Taken individually and in a manner not shown On the guideway, on which they pass through the fingers of the Finger bar 3 detected and fed to the forming tool 1 can be. The finger bar 3 is programmable Linear drive 12 connected, the whole program perform any forward and return strokes can, as indicated in Fig. 1 by arrows of different lengths is.

Wie bereits erwähnt, zeigen die Figuren 1 und 2 den Zustand, bei welchem ein Streifen 2 um einen letzten Schritt in das Umformwerkzeug 1 vorgeschoben ist. Der vorderste Zahn 8 am vorderen Ende der Fingerstange 3 befindet sich in unmittelbarer Nähe des Umformwerkzeugs ohne jedoch mit demselben in Konflikt zu geraten. Schon vor dem Arbeitshub des Umformwerkzeugs kann die Fingerstange zurückgezogen werden, sofern dies erforderlich ist. In Fig. 2 ist auch schon die Position eines neu aufgelegten Streifens 2 ersichtlich. Unter diesem Streifen wird nun die Fingerstange 3 um einen relativ grossen Hub in die Position gemäss Figur 3 zurückgezogen, in welcher der hinterste Finger 4 der Fingerstange 3 gerade hinter die Hinterkante des Streifens 2 greift. Die Fingerstange 3 mit dem Streifen 2 wird dann um einen praktisch gleichen Schritt nach vorne verschoben, in die Position gemäss Figur 4. Damit gelangt der Streifen 2 soweit in das Umformwerkzeug 1, dass die erste Bearbeitung erfolgen kann. Die Fingerstange 3 ist dabei wieder bis in unmittelbare Nähe des Umformwerkzeugs 1 vorgeschoben worden und muss nun zum weiteren Vorschieben des Streifens 2 erneut zurückgezogen werden. Dabei kann nun der nächste Finger 5, oder der übernächste Finger 6 zum Einsatz kommen, um den Streifen weiter schrittweise vorzuschieben. Figur 5 zeigt ein weiteres Stadium, bei welchem der Streifen 2 schon zum Teil bearbeitet ist und die Fingerstange 3 zum weiteren schrittweisen Vorschieben des Streifens 2 soweit zurückgesetzt worden ist, dass der Finger 7 wirksam wird, um den Streifen weiter vorzuschieben. In einem späteren Stadium muss die Fingerstange 3 erneut zurückgezogen werden, damit der Finger 8 am vorderen Ende der Fingerstange zum Einsatz kommt, um den Streifen bis in die Endstellung gemäss Figuren 1 und 2 vorzuschieben.As already mentioned, FIGS. 1 and 2 show the state, in which a strip 2 by one last step is advanced into the forming tool 1. The foremost Tooth 8 at the front end of the finger bar 3 is in immediate vicinity of the forming tool without, however, with the same to come into conflict. Even before the working stroke of the The finger bar can be withdrawn, if necessary. 2 is already the Position of a newly placed strip 2 can be seen. Under this strip is now the finger bar 3 by one relatively large stroke retracted into the position according to FIG. 3, in which the rearmost finger 4 of the finger bar 3 grips just behind the rear edge of the strip 2. The Finger bar 3 with the strip 2 is then practical same step forward, into position according to FIG. 4. The strip 2 thus comes in as far the forming tool 1 that the first machining is done can. The finger bar 3 is again in the immediate range Near the forming tool 1 has been advanced and must now again to advance the strip 2 again be withdrawn. The next finger 5, or the next but one finger 6 are used to move the Advance stripes gradually. Figure 5 shows a further stage in which the strip 2 is already at Part is processed and the finger bar 3 for further incremental advancement of the strip 2 so far has been that the finger 7 is effective to the To advance strips further. At a later stage the finger bar 3 must be pulled back again so that the finger 8 at the front end of the finger bar for use comes to the strip to the end position according to the figures To advance 1 and 2.

Dank der Ausbildung der Fingerstange und dank ihrem programmierbaren Antrieb können nun beliebige Bedingungen erfüllt werden, beispielsweise verschieden bemessene Vorschubschritte, gegebenenfalls auch verschieden bemessene Zufuhrhübe für verschieden lange Streifen. Die Streifenführung kann nötigenfalls quer zur Vorschubrichtung bewegt werden, um zwei oder mehr Reihen des Streifens zu bearbeiten.Thanks to the design of the finger bar and thanks to its programmable Drive can now meet any conditions different feed steps, for example if necessary also different sized Feed strokes for strips of different lengths. The stripe guide can be moved across the feed direction if necessary to process two or more rows of the strip.

Figur 6 zeigt einen möglichen vollständigen Bewegungszyklus der Fingerstange 3, wobei die Zufuhr- oder Vorschubpositionen der Fingerstange jeweils ausgezogen dargestellt sind, während die Rücklaufpositionen gestrichelt dargestellt sind. Unter den Fingerstangen 3 sind die jeweiligen Positionen der Hinterkante 2' des Streifens 2 dargestellt. In Fig. 6 oben ist die zurückgezogene Ausgangsposition der Fingerstange gemäss Fig. 3 gezeigt, bei welcher der Finger 4 den Streifen 2 in der dargestellten Position erfasst. Die nächste Stellung, bei welcher die Finger 4 - 8 noch alle dargestellt sind, entspricht der ersten Bearbeitungsposition nach Fig. 4, in welcher der Streifen durch den Finger 4 vorgeschoben worden ist. Dann wird die Fingerstange schon wieder zurückgezogen in die Position, in welcher der Finger 6, von dem nur noch die Vorderkante dargestellt ist, den Streifen erfasst. Es folgen dann drei weitere Stellungen, bei welchen der Finger 6 den Streifen je um einen Schritt vorschiebt. Dann wird die Fingerstange wieder zurückgezogen in die Position 3', in welcher nun der Finger 7 den Streifen erfasst und um sieben weitere Schritte nach vorne verschiebt. Dann wird die Fingerstange erneut zurückgezogen in die Position 3'', in welcher der vorderste Finger 8 den Streifen 2 erfasst und dann um sieben weitere Schritte vorschiebt in die Endposition gemäss Figuren 1 und 2.Figure 6 shows a possible complete movement cycle the finger bar 3, the feed or feed positions the finger bar are shown in full lines, while the return positions are shown in dashed lines are. The respective positions are under the finger bars 3 the rear edge 2 'of the strip 2 shown. In Fig. 6 above is the retracted starting position of the Finger rod shown in FIG. 3, in which the finger 4 captured the strip 2 in the position shown. The next position, in which fingers 4 - 8 are still all are shown corresponds to the first processing position 4, in which the strip through the finger 4 has been advanced. Then the finger bar is already pulled back into the position in which the finger 6, of which only the front edge is shown, the Stripes captured. Then three more positions follow, in which the finger 6 the strip one step at a time advances. Then the finger bar is pulled back to position 3 ', in which finger 7 now strips recorded and moved forward by seven more steps. Then the finger bar is pulled back in the position 3 '' in which the foremost finger 8 the Strip 2 captured and then advanced seven more steps to the end position according to FIGS. 1 and 2.

Bisher ist angenommen, es sei jeweils ein einziges Fördermittel, also z. B. eine einzige Fingerstange vorhanden. Es könnten aber zum Vorschieben breiter Streifen oder Tafeln mehrere Fingerstangen nebeneinander angeordnet sein, die gleich ausgebildet sind und bewegt werden.So far Assume that there is a single grant, so e.g. B. a single finger bar available. But it could to feed wide strips or sheets several Finger poles arranged side by side be trained and moved the same.
