Description

Die Erfindung betrifft eine Vorrichtung zum Rollformen von Profilen aus Metallband, bestehend aus einer Vielzahl von in Banddurchlaufrichtung hintereinander angeordneten, auf einem Maschinentisch befestigbaren Rollformkassetten.The invention relates to a device for roll forming of profiles of metal strip, consisting of a Variety of tape in the direction of succession arranged, attachable to a machine table Roll forming cassettes.

Bisher ist es üblich, entsprechende Rollformkassetten in Banddurchlaufrichtung hintereinander auf dem Maschinentisch einer Rollformmaschine zu fixieren.So far, it is customary, corresponding Rollformkassetten in the tape passage direction one behind the other on the To fix a machine table of a roll forming machine.

Sofern die Rollformmaschine für ein anderes Profil umgerüstet werden sollte, so mußte das rollgeformte Profil aus den Rollformstationen herausgefahren werden oder aber das Profil mußte zwischen den einzelnen Rollformkassetten getrennt werden, um die Kassetten abrüsten zu können.Unless the roll forming machine for another profile had to be converted, so had the rollformed Profile be pulled out of the roll forming stations or else the profile had to be between the individual Rollform cassettes are separated to the cassettes to be able to disarm.

Dies bedeutet einen zusätzlichen Arbeitsaufwand. Sofern die entsprechenden Rollformkassetten erneut zur Formung desselben Profiles eingesetzt werden sollten, so war es wiederum erforderlich, die entsprechenden Rollformkassetten auf dem Maschinentisch zu fixieren und das Bandmaterial neu einzufädeln, was mit hohem Zeitaufwand verbunden war und auch zu Qualitätsdifferenzen führen konnte.This means an additional workload. Provided the appropriate Rollformkassetten again for shaping same profile should be used, so it was turn necessary, the corresponding Fix rollform cassettes on the machine table and re-thread the tape material, what with high Time was connected and also too Could lead to quality differences.

Aus der US-A 4 831 857 ist eine Vorrichtung zum Rollformen von Profilen aus Metallband bekannt, die aus einer Vielzahl von in Banddurchlaufrichtung hintereinander angeordneten, auf einem Maschinentisch befestigbaren Rollformkassetten oder dergleichen besteht, wobei auch Mittel zum Aufnehmen des gesamten Kassettenverbundes als zusammenhängende Montageeinheit wahlweise aus einer oder in eine Betriebsstellung ermöglicht ist. Im Stand der Technik ist hierzu eine Tragplatte vorgesehen, an der die Rollensätze befestigt sind. Die Tragplatte weist Ringösen auf, an die Aufhängemittel, beispielsweise eine Kette mit Haken, angeschlossen werden können, um die gesamte Einheit abheben zu können oder aufsetzen zu können. Die einzelnen Kassetten sind dabei nicht unmittelbar miteinander verbunden, sondern sie sind auf einem relativ schweren, schlecht handhabbaren Teil, nämlich einer Platte befestigt. Diese Platte muss zusätzlich transportiert und gehandhabt werden, wobei die Rollformkassetten zudem auf dieser Platte befestigt werden müssen.From US-A 4 831 857 a device for Roll forms of profiles made of metal strip are known a variety of in the tape passage direction arranged one behind the other, on a machine table attachable rollform cassettes or the like which also includes means for recording the entire Cassette composite as a coherent assembly unit optionally from or into an operating position is possible. In the prior art this is a Support plate provided, attached to the roller sets are. The support plate has eyelets, to the Suspension means, for example a chain with hooks, can be connected to the entire unit to be able to take off or sit up. The individual cassettes are not immediate but they are on one relatively heavy, poorly manageable part, namely attached to a plate. This plate must be in addition be transported and handled, the Rollformkassetten also attached to this plate Need to become.

Durch diese Ausbildung ist die Umrüstung erschwert. Due to this design, the conversion is difficult.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung gattungsgemäßer Art zu schaffen, die ein einfaches und schnelles Umrüsten ermöglicht.Based on this prior art is the Invention the task is based, a device generic way of creating a simple and fast changeover possible.

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass die Rollformkassetten eines Rollformkassettenverbundes zumindest im Bereich deren Schnittstellen zu benachbarten Rollformkassetten miteinander gekoppelt sind und auf deren Länge verteilt derart angeordnete Mittel zum Aufnehmen und/oder Abstützen des Kassettenverbundes aufweisen, dass der Kassettenverbund als zusammenhängende Montageeinheit wahlweise aus einer oder in eine Betriebsstellung transportierbar ist, dass die in Banddurchlaufrichtung benachbarten Rollformkassetten an ihrer dem Maschinentisch benachbarten Schnittstelle durch erste Verbindungsmittel miteinander verbunden sind, dass die Rollformkassetten an der Schnittstelle im Bereich, der vom Maschinentisch entfernt liegt, durch zweite Verbindungsmittel verbunden sind, und dass einstellbare Aufhängemittel an den Rollformkassetten angeordnet sind, so dass der vom Maschinentisch gelöste Kassettenverbund mittels eines Hebemittels als Einheit vom Maschinentisch abhebbar ist.To solve this problem, it is proposed that the Rollformkassetten a Rollformkassettenverbundes at least in the area of their interfaces too adjacent Rollformkassetten coupled together are arranged and distributed along the length thereof Means for receiving and / or supporting the Have cassette composite that the cassette composite as a contiguous assembly unit optionally from a or transportable into an operating position is that the adjacent in the tape passage direction Rollform cassettes at their the machine table adjacent interface by first Connecting means are interconnected, that the Rollformkassetten at the interface in the area, the from the machine table, by second Connecting means are connected, and that adjustable Suspension means arranged on the Rollformkassetten are so that the one loosened from the machine table Cassette composite by means of a lifting device as a unit can be lifted off the machine table.

Bevorzugt ist vorgesehen, dass die einstellbaren Aufhängemittel an den zweiten Verbindungsmitteln angeordnet sind. It is preferably provided that the adjustable Suspension means on the second connection means are arranged.

Dadurch, dass die einzelnen Rollformkassetten an den Schnittstellen einerseits nahe des Maschinentisches und andererseits nahe ihres freien, vom Maschinentisch abragenden Endes mit Verbindungsmitteln verbunden sind, ist ein fester Verbund zwischen den Rollformkassetten erreicht. Durch die Aufhängemittel ist es möglich, diesen Kassettenverbund mit einer Krananlage, die mit einer entsprechenden Hebetraverse ausgerüstet ist, anzuheben. Zum Umrüsten ist es daher lediglich erforderlich, die Rollformkassetten vom Maschinentisch zu lösen und mittels der Hebetraverse anzuheben, wobei eine Durchbiegung der Rollformkassetten in den Verbindungsbereichen vermieden ist. Das mit dem Verbund von Rollformkassetten zu formende Profil kann in den Rollformkassetten eingelagert bleiben, so dass bei Neuanlauf (Wiedereinsatz des Rollformkassettenverbundes) kein neues Einfädeln des Bandmaterials erforderlich ist, sondern lediglich an das aus dem Eingangsrollensatz herausragende Ende des Bandes ein entsprechendes Metallband angeschweißt werden kann, um die Neuaufnahme der Produktion vornehmen zu können. Damit ist ein sehr schnelles und wenig zeitaufwendiges Umrüsten auf ein neues Profil möglich, wobei bei Wiederinbetriebnahme eines früher genutzten Kassettenverbundes eine Qualitätserhaltung gewährleistet ist.The fact that the individual Rollformkassetten to the Interfaces on the one hand near the machine table and on the other hand, near her free, from the machine table protruding end are connected to connecting means, is a strong bond between the rollform cassettes reached. The suspension means it is possible This cassette assembly with a crane system that with a corresponding lifting beam is equipped, to raise. For conversion, it is therefore only required, the rollform cassettes from the machine table to solve and lift by means of the lifting beam, wherein a deflection of Rollformkassetten in the Connection areas is avoided. That with the composite from Rollformkassetten to be molded profile can in the Rollformkassetten remain stored, so that at Reboot (re - use of the Rollformkassettenverbundes) no re-threading the Band material is required, but only to the protruding from the input roller set end of Bandes a corresponding metal band welded can be to the resumption of production to be able to make. This is a very fast and little time-consuming conversion to a new profile possible, whereby when restarting an earlier used cassette composite a quality preservation is guaranteed.

Bevorzugt ist zudem vorgesehen, daß die ersten Verbindungsmittel durch miteinander verbundene, oder verbindbare Laschen gebildet sind.Preferably, it is also provided that the first Connecting means through interconnected, or connectable tabs are formed.

Desweiteren ist bevorzugt, daß die zweiten Verbindungsmittel durch jeweils einen die Schnittstelle überbrückenden, an den Endelementen der Rollformkassetten befestigten Träger mit Aufhängeöse gebildet sind.Furthermore, it is preferred that the second Connecting means by one the interface bridging, at the end elements of the Rollformkassetten fastened carrier with hanging loop are formed.

Dabei kann bevorzugt vorgesehen sein, daß die Aufhängeöse höhenverstellbar ist.It may preferably be provided that the Hanging loop is height adjustable.

Besonders bevorzugt ist, daß die zweiten Verbindungsmittel, insbesondere die Träger, biegesteif sind.It is particularly preferred that the second Connecting means, in particular the carrier, rigid are.

Desweiteren ist bevorzugt vorgesehen, daß die an den Enden des Kassettenverbundes vorgesehenen Aufhängemittel durch an den Endelementen des Rollformkassettenverbundes fixierte, biegesteife Träger mit Aufhängeöse gebildet sind. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung gezeigt und im folgenden näher beschrieben.Furthermore, it is preferably provided that the at the Ends of the cassette assembly provided Suspension means on at the end elements of Rollformkassettenverbundes fixed, rigid support are formed with hanging loop. An embodiment The invention is shown in the drawing and in described in more detail below.
