Description

Die Erfindung bezieht sich auf eine Vorrichtung in Verbindung mit einer Anlage zum Ausstanzen von Blechteilen aus bandförmigem Rohblech, das in Rollen (sog. Coils) angeliefert wird, mit einem kassettenartigen Behälter zur Aufnahme eines Coils, der von einem Rahmen mit Stützrollen für ein Coil gebildet ist.The invention relates to a device in connection with a system for punching sheet metal parts from strip-shaped raw sheet, which is delivered in coils, with a cassette-like container for receiving a coil, which is formed by a frame with support rollers for a coil is.

In der Stanztechnik ist es üblich, das benötigte Halbzeug, also das Rohblech, in Rollen zu liefern, welche als Coils bezeichnet werden. Normalerweise werden diese Coils bis zum Ende aufgearbeitet. Dafür ist der eigentlichen Stanzmaschine eine justierbare Haspel zum Nachschub des Bandmaterials vom Coil zugeordnet.In stamping technology, it is common to supply the required semi-finished product, i.e. the raw sheet, in rolls, which are referred to as coils. Usually these coils are refurbished to the end. For this purpose, the actual punching machine is assigned an adjustable reel for feeding the strip material from the coil.

Aus der JP-A-58 145 315 ist eine Anlage zum Ausstanzen von Blechteilen aus Rohblech bekannt mit einer Stanzmaschine und einer Zuführeinrichtung für Bandmaterial, wobei der Stanzmaschine ein lateral verschiebbarer Schlitten für kassettenartige Behälter zugeordnet ist. Dabei geht es im wesentlichen darum, mittels Programmsteuerung die Rüstzeiten zu vermindern und die Arbeitseffektivität zu erhöhen, wobei beim Bandwechsel eine neue Kassette automatisch in die gewünschte Position verschoben werden kann. Dazu müssen die Kassetten identisch als Zuführvorrichtung für gehaspeltes Bandmaterial ausgebildet sein.From JP-A-58 145 315 a system for punching sheet metal parts from raw sheet metal is known with a punching machine and a feed device for strip material, the punching machine being assigned a laterally displaceable slide for cassette-like containers. It is essentially a matter of reducing the set-up times and increasing the work efficiency by means of program control, a new cassette being able to be automatically moved into the desired position when the tape is changed. For this purpose, the cassettes must be designed identically as a feed device for coiled strip material.

Beispielsweise aus der DE-C-884 940 ist eine derartige Vorrichtung zum Zuführen des gehaspelten Bandmaterials bekannt, bei welcher die Haspel Mittel zum genauen Führen des Bandes aufweist. Die Beschickung einer solchen Haspel ist vergleichsweise umständlich und zeitaufwendig, so daß sie sich nur bei längerer Betriebszeit pro Auftrag und großer Anzahl auszustanzender Teile lohnt.From DE-C-884 940, for example, such a device for feeding the reeled strip material is known, in which the reel has means for precisely guiding the strip. The loading of such a reel is comparatively cumbersome and time-consuming, so that it is only worthwhile with a long operating time per order and a large number of parts to be punched out.

Darüber hinaus sind aus der FR-A-21 78 232 auf einem Schlitten angeordnete Kassetten für Coils vorbekannt, bei dem über ein Kettengetriebe der seitliche Abstand der Kassettenwände einstellbar ist. Die Kassetten selbst sind wieder identisch aufgebaut, wobei mit einer solchen Einrichtung insbesondere wieder die Rüstzeit beim Kassettenwechsel verringert werden soll. Eine entsprechende Aufnahmeeinrichtung für mehrere Coils wird in der US-A-34 72 463 beschrieben. Dabei sind die Coils nebeneinander in einem offenen, lateral verschiebbaren Behälter auf durchgehenden Rollen gelagert und wird das Bandende zwischen zwei Drehrollen durchgezogen. Bei der US-A-38 10 588 ist zwar ein geschlossener Behälter für ein einziges Coil aus elastischem Material mit Lagerrollen und Durchzieheinrichtung in der Behälterwand vorhanden. Diese Einrichtung erscheint jedoch für Blechbänder ungeeignet. Speziell dafür ist aus der DE-C-0 620 298 eine Maschine zum Entrollen von Wickelbünden, insbesondere von aufgerolltem bandförmigen Walzgut bekannt, bei der insbesondere der Innenradius des Coils über eine Andruckrolle justierbar ist. Diese Maschine muß jedoch jeweils mit einem Coil geladen werden, wodurch erhebliche Umrüstarbeiten notwendig sind.In addition, from FR-A-21 78 232 cassettes for coils arranged on a carriage are known, in which the lateral spacing of the cassette walls can be adjusted via a chain gear. The cassettes themselves are constructed identically again, with such a device, in particular, to reduce the set-up time when changing the cassette. A corresponding receiving device for several coils is described in US-A-34 72 463. The coils are stored next to each other in an open, laterally displaceable container on continuous rollers and the end of the strip is pulled between two rotating rollers. In US-A-38 10 588 there is a closed container for a single coil of elastic material with bearing rollers and pulling means in the container wall. However, this device appears unsuitable for metal strips. DE-C-0 620 298 specifically discloses a machine for unrolling winding bundles, in particular rolled-up strip-shaped rolling stock, in which the inner radius of the coil in particular can be adjusted using a pressure roller. However, this machine must be loaded with a coil, which means that considerable conversion work is necessary.

Insgesamt sind also die bekannten Einrichtungen nur dann sinnvoll zu verwenden, wenn umfangreiche Losgrößen bei der Fertigung vorliegen und der Coilwechsel schnell erfolgen soll.Overall, the known devices can only be used sensibly if there are large batch sizes in production and the coil change is to be carried out quickly.

Sofern nur kleine Losgrößen vorliegen, insbesondere auch bei kleinen Stanzteilen, ist der Materialverbrauch pro Los sehr niedrig. Dies bedeutet, daß ein Coil, von dem nur eine geringe Bandlänge benötigt wird, über mehrere nicht anschließende Aufträge stückweise abgearbeitet werden müßte ; zwischendurch ist immer das Umrüsten mit zeitaufwendigem Beschicken der Haspel notwendig. Der Wechsel von nicht abgearbeiteten Coils verursacht aber insbesondere durch das Zusammenbinden oder Öffnen der Restcoils zusätzliche Rüstzeiten. Daneben ist das Handhaben von dickem oder auch sehr dünnem Halbzeug umständlich und sogar unfallgefährlich. Restcoils aus dicken Werkstoffen und hoher Festigkeit federn nach dem Abschneiden nach der Haspel bei Störung oder am Ende des Auftrages auf. Restcoils aus dünnen Werkstoffen fallen dagegen nach der Abnahme von der Haspel in sich zusammen.If only small lot sizes are available, especially for small stamped parts, the material consumption per lot is very low. This means that a coil, of which only a small strip length is required, would have to be processed piece by piece over several non-subsequent orders; in between, it is always necessary to change over with time-consuming loading of the reel. However, changing unprocessed coils causes additional set-up times, particularly when the remaining coils are tied together or opened. In addition, the handling of thick or very thin semi-finished products is cumbersome and even dangerous. Residual coils made of thick materials and high strength spring up after cutting after the reel in the event of a malfunction or at the end of the order. Residual coils made of thin materials, on the other hand, collapse after being removed from the reel.

Aus obigen Gründen wurde bisher bei Aufträgen mit geringen Losgrößen nicht vom Coil gearbeitet, sondern wurden die Stanzteile aus Streifen gefertigt. Dabei erfolgt das Zuschneiden der Streifen mittels einer Schlagschere aus einer Tafel von Rohblech. Die Blechtafeln und die bereits zugeschnittenen Streifen sind daher günstigerweise im Bereich der Stanzerei zu lagern. Damit durch Fehlstanzungen die Loszahl nicht unterschritten wird, sind im allgemeinen mehr Streifen, als durch die Losgröße eigentlich errechnet, bereitzustellen. Übriggebliebene Streifen gehen in das Streifenlager zurück oder werden zum Stanzabfall gegeben. Entsprechend der Anzahl der verschiedenen zu verarbeitenden Werkstoffe und der Streifenabmessungen muß daher die Größe des Blechlagers angepaßt werden.For the above reasons, orders with small batch sizes have not been worked from the coil, but the stamped parts have been made from strips. The strips are cut using a pair of guillotine shears from a sheet of raw sheet metal. The metal sheets and the strips that have already been cut are therefore conveniently stored in the punching area. To ensure that the number of lots is not fallen short of due to incorrect punching, more strips are generally to be provided than actually calculated from the lot size. Leftover strips go back to the strip storage or are added to the punch waste. The size of the sheet metal bearing must therefore be adapted in accordance with the number of different materials to be processed and the strip dimensions.

Die Beschickung des Pressenwerkzeuges mit einzelnen Streifen geschieht im allgemeinen von Hand. Eine automatische Streifenverarbeitung wäre nur bei vorhandenen Restgittern möglich. Am Beginn des Streifens muß angestanzt werden und es kann, um halbe Teile zu vermeiden, der Streifen nur bis auf einen vom Stanzwerkzeug vorgegebenen Rest verarbeitet werden. Nach Beendigung des Stanzbetriebes muß der Reststreifen aus dem Werkzeug gezogen werden.The press tool is usually loaded with individual strips by hand. Automatic strip processing would only be possible with existing skeletons. At the beginning of the strip, punching must be carried out and, in order to avoid half parts, the strip can only be processed except for a remainder specified by the punching tool. After the punching operation has ended, the remaining strip must be pulled out of the tool.

Beim Stand der Technik bleibt aufgrund der dargestellten Probleme die Materialausnutzung gering, die Hubfrequenz der Stanzmaschine niedrig und durch das häufige Streifenstanzen die Wahrscheinlichkeit von Fehlstanzungen bzw. einer Werkzeugbeschädigung hoch.In the prior art, due to the problems presented, the material utilization remains low, the stroke frequency of the punching machine remains low and the probability of incorrect punching or tool damage is high due to the frequent strip punching.

Aufgabe der Erfindung ist es daher, eine Vorrichtung anzugeben, die sowohl als Lagereinrichtung als auch als Ablaufeinrichtung für Coils verwendet werden kann und die in Verbindung mit einer Anlage zum Ausstanzen von Blechteilen von Coils angewendet werden soll.The object of the invention is therefore to provide a device which is used both as a storage device and as a drain device for coils can be used and which is to be used in connection with a system for punching sheet metal parts from coils.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß der Rahmen eine Zentriereinrichtung für den Außen- und/oder Innendurchmesser des Coils sowie eine auf unterschiedliche Breite einstellbare seitliche Führung für das Coil aufweist, wobei als Zentriereinrichtung im Rahmen nachstellbare Rollen zur Anpassung an den äußeren und/oder inneren Durchmesser des Coils angeordnet sind und die Führung durch einen seitlichen Deckel des Rahmens gebildet wird, der zum Einsetzen eines Coils ausschwenkbar ist, und daß im Rahmen eine vertikal verschiebbare Einrichtung zum Durchführen des vom Coil abgezogenen bandförmigen Rohbleches angeordnet ist, die gleichermaßen eine Klemmvorrichtung für das Bandende bildet.The object is achieved in that the frame has a centering device for the outside and / or inside diameter of the coil and a lateral guide for the coil which can be adjusted to different widths, with adjustable rollers in the frame as a centering device for adaptation to the outer and / or inner diameter of the coil are arranged and the guide is formed by a side cover of the frame, which can be swung out for the insertion of a coil, and that in the frame a vertically displaceable device for carrying out the strip-shaped raw sheet pulled off the coil is arranged, which is also a clamping device for forms the end of the tape.

Die erfindungsgemäße Vorrichtung kann in eine vorhandene Anlage mit lateral verschiebbarem Schlitten der Zuführeinrichtung des Bandes integriert werden. Dabei können nunmehr zur auftragsbezogenen Bearbeitung kleiner Losgrößen mehrere erfindungsgemäße Vorrichtungen mit zu Coils gelagerten Blechbändern unterschiedlicher Breite und/oder Dicke sowie aus unterschiedlichen Werkstoffen vorhanden sein, wobei jeweils die der Stanzmaschine zugeordnete Vorrichtung aktiviert ist und von dort das Bandende in einer Abziehvorrichtung der Stanzmaschine eingeführt wird. Nach Abarbeitung des Auftrages wird das Bandende des Coils in der Einrichtung zum Durchführen des Bandes festgeklemmt und steht dort für einen neuen Bearbeitungsvorgang zur Verfügung.The device according to the invention can be integrated into an existing system with a laterally displaceable slide of the feed device for the strip. For order-related processing of small batch sizes, several devices according to the invention can now be provided with sheet metal strips of different widths and / or thicknesses and of different materials stored in coils, the device assigned to the punching machine being activated in each case and from there the strip end being introduced into a pulling device of the punching machine . After the order has been processed, the end of the coil is clamped in the device for carrying out the strip and is available there for a new processing operation.

Vorteilhafterweise hat bei der erfindungsgemäßen Vorrichtung der Rahmen Quertraversen als Standfläche und/oder als Träger des Deckels. Ein solcher Rahmen ist ohne weiteres in den lateral zur Stanzmaschine verschiebbaren Schlitten der Gesamtanlage einsetzbar. Bestimmungsgemäß dient die Vorrichtung sowohl als Lager für die Coils als auch als Ablaufeinrichtung. Vorzugsweise sind die Scharniere für den herausschwenkbaren Dekkel und auch die Verriegelung für den Deckel verschiebbar gelagert, so daß beispielsweise von ca. 25 bis 180 mm verschieden breite Rohblechbänder eingesetzt werden können. Damit kann der Deckel an die jeweilige Breite des Coils angepaßt werden, wodurch immer eine hinreichende seitliche Führung gewährleistet ist. Damit das Coil bei ruckartigem Abzug nicht aus der Kassette gezogen wird, sind vorzugsweise zwei nachstellbare Rollen vorgesehen, die von oben an den Außendurchmesser oder von innen an den Innendurchmesser des Coils herangeführt und dem sich beim Stanzbetrieb verändernden Durchmesser angepaßt werden können. Da die an der frontalen Seite der Kassette angeordnete Einrichtung zum Durchführen des Bandes mit der zugehörigen Klemmvorrichtung vertikal verschiebbar ist, kann sie den unterschiedlichen Einlaufhöhen angeglichen werden.In the device according to the invention, the frame advantageously has cross members as a base and / or as a support for the cover. Such a frame can easily be used in the slide of the overall system which can be moved laterally to the punching machine. The device serves as both a storage for the coils and a drain device. Preferably, the hinges for the pivoting lid and the locking mechanism for the lid are slidably mounted so that, for example, roughly 25 to 180 mm wide sheet metal strips can be used. So that the lid can be adapted to the respective width of the coil, which always ensures sufficient lateral guidance. So that the coil is not pulled out of the cassette in the event of a jerky pull-off, two adjustable rollers are preferably provided, which are guided from above to the outside diameter or from the inside to the inside diameter of the coil and can be adapted to the changing diameter during punching operation. Since the device arranged on the frontal side of the cassette for carrying out the tape can be moved vertically with the associated clamping device, it can be adapted to the different inlet heights.

Durch die Erfindung ist also jederzeit ein sofortiger Zugriff zu Bandmaterial unterschiedlicher Breite und/oder Dicke sowie Werkstoff möglich. Es kann nun ein schnelles Umrüsten erfolgen. Es ergeben sich somit aufgrund der Erfindung wesentliche Vereinfachungen im Routinebetrieb von Stanzereien, wodurch die Automatisierung weiter verbessert wird.The invention therefore enables immediate access to strip material of different widths and / or thicknesses and material at any time. A quick changeover can now take place. The invention therefore results in significant simplifications in the routine operation of stamping shops, as a result of which the automation is further improved.

Durch die beschriebene Lagerung kann der Deckel 3 einerseits zum Einsetzen eines Coils in die Kassette weggeschwenkt werden ; dadurch, daß die Scharniere und die Verriegelung für den Deckel 3 stufenlos verschiebbar gelagert sind, können andererseits verschieden breite Coils, beispielsweise im Bereich von 25 bis 180 mm, eingesetzt werden, Der Deckel 3 ist somit an die jeweilige Breite des Coils anpaßbar, so daß durch den Rahmen 1 auf der einen Seite und den Deckel 3 auf der anderen Seite die seitliche Führung für das Band gewährleistet ist.Due to the storage described, the cover 3 can be pivoted away on the one hand for inserting a coil into the cassette; in that the hinges and the locking mechanism for the cover 3 are mounted so that they can be moved continuously, On the other hand, coils of different widths can be used, for example in the range from 25 to 180 mm. The lid 3 can thus be adapted to the respective width of the coil, so that the frame 1 on one side and the lid 3 on the other side lateral guidance for the belt is guaranteed.

In der Fig. 3 ist ein Coil 20 bzw. 20' angedeutet. Es liegt mit seinem Außendurchmesser auf vier querliegenden Stützrollen 6 auf, welche auch aus Fig. 2 ersichtlich sind. Auf dem Umfang des Coils befinden sich weitere Rollen 7, welche in Aussparungen 8 des Deckels 3 bzw. des Rahmens 1 zentral nach innen nachführbar sind. Die Rollen 7 werden von oben auf den Außendurchmesser des Coils 20 herangeführt und können sich dessen veränderndem Außendurchmesser anpassen. Damit ist gleichermaßen sichergestellt, daß das Coil 20 bei ruckartigem Abzug nicht aus dem genannten Behälter gezogen werden kann. Die Rollen 7 können auch zentrisch in den Nuten 8 an den Innendurchmesser des Coils 20 herangeführt werden und als Zentriereinrichtung wirken. Auch Kombinationen von Innen- und Außenrollen, die jeweils in geeigneter Stellung fixiert werden, sind möglich, was in Fig. 3 angedeutet ist.A coil 20 or 20 'is indicated in FIG. 3. Its outer diameter rests on four transverse support rollers 6, which can also be seen in FIG. 2. On the circumference of the coil there are further rollers 7, which can be adjusted centrally inwards in recesses 8 of the cover 3 or the frame 1. The rollers 7 are brought up from above onto the outside diameter of the coil 20 and can adapt to its changing outside diameter. This also ensures that the coil 20 cannot be pulled out of the said container in the event of a jerky withdrawal. The rollers 7 can also be guided centrally in the grooves 8 to the inside diameter of the coil 20 and act as a centering device. Combinations of inner and outer rollers, each of which is fixed in a suitable position, are also possible, which is indicated in FIG. 3.

Frontal am Behälter befindet sich weiterhin eine vertikal verschiebbare Durchzugs- und Klemmvorrichtung 15 für den Bandanfang. Diese besteht im einzelnen aus einer höhenverschiebbaren Rolle 16, der ein mittels eines handbetätigbaren Rändelrades 17 betätigbares Klemmstück 18 zugeordnet ist.On the front of the container there is also a vertically displaceable pulling and clamping device 15 for the beginning of the band. This consists in detail of a height-displaceable roller 16, to which a clamping piece 18, which can be actuated by means of a hand-operated knurled wheel 17, is assigned.

Aus Fig. 2 wird deutlich, daß die beschriebenen kassettenartigen Behälter bis 111 auf unterschiedliche Breite eingestellt sind. Wie erwähnt, können Coils mit den Abmessungen 25 bis 180 mm sowie auch unterschiedlicher Dicke, beispielsweise zwischen 0,5 bis 3 mm, gelagert werden, wobei das Halbzeug auch aus unterschiedlichen Werkstoffen bestehen kann.From Fig. 2 it is clear that the described cassette-like containers up to 111 are set to different widths. As mentioned, coils with the dimensions 25 to 180 mm and also of different thicknesses, for example between 0.5 to 3 mm, can be stored, the semi-finished product also being able to consist of different materials.

Mit der beschriebenen Anlage kann die Herstellung von Stanzteilen nach einem neuen Arbeitsverfahren betrieben werden : In der Nähe der Stanzmaschine ist der Schlitten mit verschiedenen Kassetten stationiert. Damit ist ein sofortiger Zugriff und ein schnelles Umrüsten auf eine neue Bandbreite bzw. Material möglich. Da der Bandanfang jeweils in der Klemmvorrichtung fixiert ist, kann eine Zuführung zum Stanzwerkzeug nach entsprechender Lateralverschiebung schnell erfolgen.With the system described, the production of stamped parts can be carried out according to a new working method: the slide with various cassettes is stationed near the stamping machine. This enables immediate access and quick changeover to a new range or material. Since the beginning of the tape is fixed in the clamping device, feeding to the punching tool can take place quickly after a corresponding lateral displacement.

Auch kleinere Stückzahlen von Stanzteilen lassen sich nunmehr in wirtschaftlicher Weise von einem Coil abarbeiten. Wird die Arbeit unterbrochen, kann das Band festgeklemmt und außerhalb der Aufnahmevorrichtung abgeschnitten werden, so daß die Arbeiten zum beliebigen Zeitpunkt sofort wieder fortsetzbar sind. Langwierige Umrüstarbeiten durch Justage einer Haspel sind nunmehr überflüssig.Smaller quantities of stamped parts can now also be processed economically from a coil. If the work is interrupted, the tape can be clamped and cut off outside the holding device, so that the work can be continued again at any time. Lengthy retrofitting work by adjusting a reel is now superfluous.

Eine Stanzmaschine läßt sich also beim beschriebenen Verfahren nicht nur wirtschaftlicher ausnutzen ; auch Fehlstanzungen und Werkzeugbeschädigungen werden sich wirksam verringern.A punching machine can therefore not only be used more economically in the method described; Incorrect punching and tool damage will also be reduced effectively.
