Description

Die Erfindung bezieht sich auf eine Überleitvorrichtung für Bänder, die zwischen einer Ablaufhaspel und einer Bandbe- oder Bandverarbeitungseinrichtung verfahrbar angeordnet ist, bestehend aus einem mit einem Ende in den Zwickel von Bandanfang und Bund einführbaren, schwenkbaren Leittisch und einem insbesondere von Rollen gebildeten Klemmelementenpaar, von dem ein Klemmelement am anderen Ende des Leittisches und im wesentlichen in der Führungsebene des Leittisches angeordnet ist.The invention relates to a transfer device for tapes, which is arranged to be movable between a decoiler and a tape processing or tape processing device, consisting of a pivotable guide table that can be inserted at one end into the gusset of the tape beginning and the collar, and a pair of clamping elements, in particular formed by rollers, of which a clamping element is arranged at the other end of the control table and essentially in the guide plane of the control table.

Überleitvorrichtungen dieser Art sind in verschiedenen Ausführungen bekannt (DD-PS 33 557; DD-PS 27 545). Bei diesen Überleitvorrichtungen ist dem Bund eine Andrückrolle zugeordnet, die gegen die äußere Lage des Bundes drückt und auf diese Weise den Bund am Aufspringen hindert. Zum Verfahren der Überleitvorrichtung zwischen der Haspel und der nachgeordneten Bandbe- oder Bandverarbeitungseinrichtung ist die Überleitvorrichtung auf einem Schwenkarm derart angeordnet, daß der Überleittisch unter den Bandanfang des von oben abzuziehenden Bandes angeschwenkt werden kann. Mit einer solchen Vorrichtung ist es nur möglich, einen Bandanfang zu erfassen, der im oberen Bereich des Bundes liegt. In der Praxis besteht aber auch die Forderung, unten am Bund liegende Bandanfänge zu erfassen und nachgeordneten Bandbe- oder Bandverarbeitungseinrichtungen zuzuführen.Transfer devices of this type are known in various designs (DD-PS 33 557; DD-PS 27 545). In these transfer devices, a pressure roller is assigned to the federal government, which presses against the outer layer of the federal government and in this way prevents the federal government from springing open. The transfer device is for moving the transfer device between the reel and the downstream strip processing or processing device arranged on a swivel arm in such a way that the transfer table can be swiveled under the beginning of the belt of the belt to be pulled off from above. With such a device, it is only possible to detect a beginning of the tape that lies in the upper region of the federal government. In practice, however, there is also the requirement to record the beginning of the strip at the bottom of the bundle and to feed downstream strip processing or strip processing equipment.

Der Erfindung liegt die Aufgabe zugrunde, eine Überleitvorrichtung der eingangs genannten Art zu schaffen, die sowohl für oben am Bund als auch für unten am Bund liegende Bandanfänge verwendbar ist.The invention has for its object to provide a transfer device of the type mentioned, which can be used both for the top of the collar and for the bottom of the band beginning of the band.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Leittisch sowohl auf seiner Ober- als auch seiner Unterseite eine Führungsebene für das Band aufweist und daß die Klemmelemente gegeneinander derart verstellbar sind, daß ihr Durchtrittsspalt wahlweise in der oberen oder unteren Führungsebene des Leittisches liegt. Bei der erfindungsgemäßen Überleitvorrichtung ist im Vergleich zu bekannten Überleitvorrichtungen nur ein unwesentlicher Mehraufwand zu treiben, um einen Bandanfang sowohl oben auf dem Bund als auch unten am Bund erfassen und zur nachgeordneten Bandbe- oder Bandverarbeitungseinrichtung überführen zu können. Der Leittisch braucht lediglich so ausgestaltet zu sein, daß er nicht nur an einer Seite, sondern an beiden Seiten das Band führen kann, während die Klemmelemente, insbesondere Klemmrollen, auf die beiden Führungsebenen umstellbar sein müssen.This object is achieved in that the guide table has a guide plane for the belt on both its top and bottom and that the clamping elements are mutually adjustable such that their passage gap is either in the upper or lower guide plane of the guide table. In the transfer device according to the invention, in comparison to known transfer devices, only an insignificant additional effort is required in order to be able to detect a tape start both on the top and on the bottom of the collar and to transfer it to the downstream tape processing or processing device. The guide table only needs to be designed in such a way that it can guide the belt not only on one side but on both sides, while the clamping elements, in particular clamping rollers, have to be convertible to the two guide levels.

Die Umstellbarkeit der beiden Klemmelemente läßt sich auf verschiedene Art und Weise konstruktiv verwirklichen.The convertibility of the two clamping elements can be implemented constructively in various ways.

Nach einer ersten Ausgestaltung der Erfindung können die Klemmelemente mittels Schwingen gegenüber dem Leittisch verschwenkbar sein. In diesem Fall liegt je nach Lage der Führungsebene das eine oder das andere Klemmelement in der Ebene des Leittisches, während das zweite Klemmelement dann die Aufgabe hat, nach Einführen des Bandanfanges diesen gegen das in der Führungsebene des Leittisches liegende Klemmelement zu drücken.According to a first embodiment of the invention, the clamping elements can be pivoted relative to the guide table by means of swinging. In this case, depending on the position of the guide level, one or the other clamping element lies in the level of the guide table, while the second clamping element then has the task of pressing it against the clamping element lying in the guide level of the control table after inserting the beginning of the tape.

Nach einer Alternative ist es nicht erforderlich, daß beide Klemmelemente an Schwingen gelagert sind. In diesem Fall ist nur das außerhalb der Führungsebene liegende Klemmelement mittels einer Schwinge gegenüber dem Leittisch verschwenkbar und eines der beiden Klemmelemente teleskopierbar. Die Teleskopierbarkeit eines der beiden Klemmelemente ist nötig, damit das an der Schwinge gelagerte Klemmelement das in der Führungsebene verbleibende Klemmelement passieren kann.According to an alternative, it is not necessary that both clamping elements are mounted on rockers. In this case, only the clamping element lying outside the guide plane can be pivoted relative to the guide table by means of a rocker and one of the two clamping elements can be telescoped. The telescoping ability of one of the two clamping elements is necessary so that the clamping element mounted on the rocker can pass through the clamping element remaining in the guide plane.

Damit die äußeren Umgänge des Bundes nicht aufspringen, wirkt auf sie eine Andrückrolle mindestens solange ein, als der Bandanfang von der Überleitvorrichtung noch nicht erfaßt ist. Diese Andrückrolle ist vorzugsweise im Bereich des oberen Scheitels des Bundes angeordnet. Sie hält dann auch den Bandanfang in einer Position, in der er von einer Überleitvorrichtung problemlos erfaßt werden kann. Falls jedoch der Bandanfang unterhalb des Bundes erfaßt werden soll, ist es erforderlich, Hilfsmittel zur Führung des Bandanfanges am Bund vorzusehen. Dies läßt sich nach einer Ausgestaltung der Erfindung dadurch verwirklichen, daß die Andrückrolle von der verfahrbaren Überleitvorrichtung getragen wird.So that the outer circumferences of the federal government do not spring open, a pressure roller acts on them at least as long as the beginning of the tape has not yet been gripped by the transfer device. This pressure roller is preferably arranged in the region of the upper vertex of the collar. It then also holds the beginning of the tape in a position in which it can be easily gripped by a transfer device. However, if the beginning of the band is to be recorded below the federal government, it is necessary to provide aids for guiding the beginning of the band on the federal government. According to one embodiment of the invention, this can be achieved in that the pressure roller is carried by the movable transfer device.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Im einzelnen zeigen:

The invention is explained in more detail below with the aid of a drawing representing an exemplary embodiment. In detail show:
1 to 3
a transfer device between a decoiler and a strip processing device in a schematic representation in side view in different operating phases when transferring a strip start from the upper region of a bundle and
4 to 6
1 to 3 in different operating phases when transferring a tape start from the lower region of a bundle.

Auf einer Ablaufhaspel 1 ist ein Bund 2 aus Metallband angeordnet. Das Metallband 3 wird in einer Bearbeitungseinrichtung 4, z.B. einem Richtapparat, bearbeitet. Am Eingang des Richtapparates ist ein aufeinander zustellbares, das Band 3 einklemmendes Treibrollenpaar 5 vorgesehen. Damit das Band 3 horizontal in der hier horizontal angeordneten Bearbeitungsebene in den Richtapparat 5 unabhängig von dem sich in der Höhe während des Betriebes ändernden Ablaufpunkt 6 einläuft, ist in einem Gestell 7 eine in der Höhe verstellbare Umlenkrolle 8 angeordnet.A coil 2 made of metal strip is arranged on a decoiler 1. The metal strip 3 is processed in a processing device 4, e.g. a straightener, processed. At the entrance of the straightening apparatus, a pair of drive rollers 5, which can be clamped in place, is provided. So that the belt 3 runs horizontally into the straightening apparatus 5 in the processing plane, which is arranged horizontally here, independently of the running point 6, which changes in height during operation, a height-adjustable deflection roller 8 is arranged in a frame 7.

Zwischen der Haspel 1 und der Bandbearbeitungseinrichtung 4 sowie dem Richtapparat 5 und der Umlenkrolle 8 ist eine Überleitvorrichtung 9 auf einem Schlitten 10 angeordnet.A transfer device 9 is arranged on a carriage 10 between the reel 1 and the strip processing device 4 as well as the straightening apparatus 5 and the deflection roller 8.

Der Schlitten 10 ist auf einer Schiene 11 mittels eines hydraulischen Antriebes 12 verfahrbar.The carriage 10 can be moved on a rail 11 by means of a hydraulic drive 12.

Die Überleitvorrichtung 9 weist einen Überleittisch 13 mit einer oberen Führungsebene 13a und einer unteren Führungsebene 13b auf. Die Führungsebenen 13a,13b werden von glatten Tischflächen gebildet. Der Tisch 13 weist ein vorderes keilförmiges Ende 13c auf. Am hinteren Ende ist eine Rolle 14 vorgesehen, die ein Klemmelement bildet. Diese Rolle ist im Tisch teleskopierbar. Mit dieser Rolle 14 wirkt eine zweite Rolle 15 zusammen, die das zweite Klemmelement bildet. Diese Rolle 15 wird von einer im Schlitten 10 verschwenkbaren Schwinge 16 getragen. Sowohl der Überleittisch 13 als auch die Schwinge 16 sind unabhängig voneinander mittels in der Zeichnung nicht dargestellter hydraulischer Einrichtungen verschwenkbar.The transfer device 9 has a transfer table 13 with an upper guide level 13a and a lower guide level 13b. The guide levels 13a, 13b are formed by smooth table surfaces. The table 13 has a front wedge-shaped end 13c. At the rear end, a roller 14 is provided, which forms a clamping element. This roll is telescopic in the table. A second roller 15 cooperates with this roller 14 and forms the second clamping element. This roller 15 is carried by a rocker 16 which can be pivoted in the carriage 10. Both the transfer table 13 and the rocker 16 can be pivoted independently of one another by means of hydraulic devices not shown in the drawing.

Die Überleitvorrichtung arbeitet auf folgende Art und Weise:
Bei einem Bund 2 gemäß Fig. 1 bis 3, von dem das Band 3 im oberen Bereich abzuziehen ist, wird der Bund 2 gegen Aufspringen durch eine Andrückrolle 17 gehalten. Der Überleittisch 13 wird in die in Fig. 1 dargestellte Position verschwenkt, in der er mit seinem keilförmigen Ende 13c in den Zwickel von Bund 2 und Bandanfang 19 einführbar ist. Die Rolle 15 ist in ihre Extremlage von der Rolle 14 weggeschwenkt, so daß sich eine großer Durchtrittsspalt 20 für den Bandanfang 19 ergibt. Beim Abwickeln des Bandes gleitet der Bandanfang 19 über die Führungsebene 13a des Leittisches 13. Der Transport erfolgt zumindest so weit, daß die Spitze des Bandanfangs 19 die Rolle 14 passiert hat. Die Rolle 15 wird dann zurückgeschwenkt und klemmt den Bandanfang 19 ein. Der Schlitten 10 wird dann in Richtung der Bandbearbeitungseinrichtung 4 so weit verfahren, bis daß die Spitze des Bandanfangs im Bereich des Treibrollenpaars 5 zu liegen kommt. Damit das Band abgezogen werden kann, ist mindestens eine der Rollen 14,15 mit einer Rücklaufsperre ausgerüstet. Das Treibrollenpaar 5 wird zusammengefahren und erfaßt die Spitze des Bandanfangs. Die Rollen 14,15 werden geöffnet und der Schlitten 10 in die in Fig. 3 dargestellte Position zurückgefahren. Die Umlenkrolle 8 wird gegen das Band 3 gefahren, damit dieses horizontal in das Treibrollenpaar 5 einläuft.The transfer device works in the following way:
In a collar 2 according to FIGS. 1 to 3, from which the band 3 is to be pulled off in the upper region, the collar 2 is held against popping open by a pressure roller 17. The transfer table 13 is pivoted into the position shown in FIG. 1, in which it can be inserted with its wedge-shaped end 13c into the gusset of the collar 2 and the beginning of the band 19. The roller 15 is pivoted away from the roller 14 in its extreme position, so that there is a large passage gap 20 for the tape start 19. When the tape is unwound, the beginning of the tape 19 slides over the guide plane 13a of the guide table 13. The transport takes place at least so far that the tip of the beginning of the tape 19 has passed the roller 14. The roll 15 will then pivoted back and clamps the beginning of the tape 19. The carriage 10 is then moved in the direction of the tape processing device 4 until the tip of the tape start comes to rest in the area of the drive roller pair 5. So that the tape can be pulled off, at least one of the rollers 14, 15 is equipped with a backstop. The drive roller pair 5 is moved together and detects the tip of the beginning of the tape. The rollers 14, 15 are opened and the carriage 10 is moved back into the position shown in FIG. 3. The deflection roller 8 is moved against the belt 3 so that it runs horizontally into the drive roller pair 5.

Um die Überleitvorrichtung für den Betrieb nach den Figuren 1 bis 3 auf den Betrieb nach den Figuren 4 bis 6 umzustellen, wird die teleskopierbar am Leittisch 13 angeordnete Rolle 14 eingefahren, damit die andere Rolle 15 nach unten verschwenkt werden kann. Anstelle der Teleskopierbarkeit der Rolle 14 kann auch die Rolle 15 teleskopierbar sein, die in diesem Fall für die Verschwenkung ausgefahren wird. Als weitere Alternative ist es auch möglich, daß die Rolle 14 wie die Rolle 15 an einer Schwinge angeordnet ist, so daß sie in diesem Fall aus der Führungsebene des Leittisches 13 heraus nach unten verschwenkbar ist und die Rolle 15 in die Position der Rolle 14 geschwenkt wird. In jedem Fall ist es mit diesen Alternativen möglich, die oben auf dem Leittisch wirksame Führungsebene 13a auf die auf der Unterseite des Führungstisches angeordnete Führungsebene 13b umzustellen.In order to convert the transfer device for the operation according to FIGS. 1 to 3 to the operation according to FIGS. 4 to 6, the roller 14 arranged telescopically on the guide table 13 is retracted so that the other roller 15 can be pivoted downward. Instead of the telescopability of the roller 14, the roller 15 can also be telescopic, which in this case is extended for the pivoting. As a further alternative, it is also possible for the roller 14, like the roller 15, to be arranged on a rocker arm, so that in this case it can be pivoted downward out of the guide plane of the guide table 13 and the roller 15 is pivoted into the position of the roller 14 becomes. In any case, it is possible with these alternatives to convert the guide plane 13a effective on the top of the guide table to the guide plane 13b arranged on the underside of the guide table.

Zur Erleichterung der Erfassung des Bandanfangs eines nach den Figuren 4 bis 6 angeordneten Bundes ist am Schlitten 10 eine gegen den Bund andrückbare Rolle 21 vorgesehen. Ein weiterer Unterschied zu den Figuren 1 bis 3 besteht noch darin, daß die Umlenkrolle 8 wegen des tiefer leigenden Ablaufpunktes auf der Unterseite des Bandes 3 angeordnet ist. Im übrigen ist der Funktionsablauf der gleiche wie beim Ausführungsbeispiel der Figuren 1 bis 3.In order to facilitate the detection of the beginning of the tape of a collar arranged according to FIGS. 4 to 6, a roller 21 which can be pressed against the collar is provided on the carriage 10. A Another difference from FIGS. 1 to 3 is that the deflection roller 8 is arranged on the underside of the belt 3 because of the lower-lying drain point. Otherwise, the functional sequence is the same as in the exemplary embodiment in FIGS. 1 to 3.
