Description

Die Erfindung betrifft eine Vorrichtung zum Wickeln einer Warenbahn.The invention relates to a device for winding a web.

Bei Warenbahn-Behandlungsmaschinen ist am auslaufseitigen Ende eine Vorrichtung zum Wickeln der fortlaufend transportierten, breitgeführten Warenbahn vorgesehen. Die Warenbahn wird dabei auf einem Wickelkörper, beispielsweise einer Papphülse, zu einem Warenwickel aufgewickelt. Um einen kontinuierlichen Betrieb der Warenbahn-Behandlungsmaschine zu gewährleisten, muss daher sichergestellt werden, dass der fertige Warenwickel nach dem Querschneiden der Warenbahn abgelegt und ein neuer Wickelkörper bereitgestellt und angewickelt wird.In web-handling machines, a device for winding the continuously transported, wide-guided web is provided at the outlet end. The web is wound on a winding body, such as a cardboard tube, to a goods roll. In order to ensure continuous operation of the web-handling machine, it must therefore be ensured that the finished goods roll deposited after the cross-cutting of the web and a new bobbin is provided and wound.

Aus der DE-A-36 29 216 ist eine Vorrichtung zum Wickeln einer Warenbahn bekannt, die ein Schwenkgestell aufweist, das an seinem oberen Ende über eine Drehachse zwei paarweise zusammengeordnete, im Wendebetrieb arbeitende Tragarme trägt. Die beiden einander entgegengesetzten Enden der zweiarmig ausgebildeten Tragarme weisen Halterungen zur drehbaren Aufnahme und Lagerung je eines Wickelkörpers auf, auf den die von der Behandlungsmaschine kommende Warenbahn zu einem Wickel aufgewickelt wird. Ferner ist eine horizontal ausgerichtete Andrückwalze vorgesehen, über die die Warenbahn dem Wickelkörper zugeführt wird und die in abstützendem Kontakt mit dem Warenwickel steht.From DE-A-36 29 216 a device for winding a web is known, which has a pivoting frame, which carries at its upper end via a rotation axis two pairwise assembled, working in the reversing mode support arms. The two mutually opposite ends of the two-armed support arms have brackets for rotatably receiving and supporting each of a winding body on which the coming of the processing machine web is wound into a roll. Further, a horizontally oriented pressure roller is provided, via which the web is fed to the winding body and which is in abstützendem contact with the goods roll.

Sobald der Warenwickel fertig ist, wird das Schwenkgestell von der Andrückwalze weggeschwenkt und außerdem werden die beiden Tragarme um etwa 180° gedreht, so dass ein neuer Wickelkörper mit der Warenbahn in Kontakt kommt. Nach dem Zurückschwenken des Schwenkgestells erfolgt das Querschneiden der Warenbahn und Anwickeln des neuen Wickelkörpers.As soon as the goods roll is ready, the pivoting frame is pivoted away from the pressure roller and also the two support arms are rotated by about 180 °, so that a new winding body comes into contact with the material web. After pivoting back of the pivoting frame, the transverse cutting of the web and winding the new bobbin takes place.

Wenngleich diese bekannte Vorrichtung einen reibungslosen und kontinuierlichen Betrieb ermöglicht, sind jedoch für das Verschwenken des Schwenkgestells und das Drehen der Tragarme äußerst leistungsstarke Motoren erforderlich.Although this known device enables smooth and continuous operation, however, extremely powerful motors are required for pivoting the pivoting frame and rotating the support arms.

Die in der EP-B-0 424 423 offenbarte Vorrichtung zum Anwickeln eines neuen leeren Wickelkörpers zum Ersatz eines vollen Warenwickels geht einen anderen Weg, indem sie auf das Schwenkgestell mit den zweiarmigen Tragarmen verzichtet. Bei der Vorrichtung gemäß der EP-B-0 424 423 besteht die Vorrichtung zum Wickeln einer Warenbahn im wesentlichen aus einer Einrichtung zum Zuführen eines Wickelkörpers, auf den die Warenbahn zu einem Warenwickel aufgewickelt wird, einer ersten, horizontal ausgerichteten Wickelwalze, über die die Warenbahn dem Wickelkörper zugeführt wird, und einer zweiten, horizontal ausgerichteten Wickelwalze, die in abstützendem Kontakt mit dem Warenwickel steht und gemeinsam mit dem fertigen Warenwickel von der ersten Wickelwalze wegschwenkbar ist. Außerdem wird der Warenwickel an den Enden des Wickelkörpers in Führungsschienen geführt.The disclosed in EP-B-0 424 423 device for winding a new empty bobbin to replace a full goods wrap goes another way by dispensing with the pivot frame with the two-armed support arms. In the device according to EP-B-0 424 423, the device for winding a material web consists essentially of a device for feeding a wound body onto which the web is wound into a goods roll, a first, horizontally oriented winding roll over which the web the winding body is fed, and a second, horizontally oriented winding roller, which is in abstützendem contact with the goods roll and is wegschwenkbar together with the finished goods roll of the first winding roller. In addition, the goods winding is guided at the ends of the winding body in guide rails.

Bei dieser bekannten Vorrichtung wird ein neuer Wickelkörper von oben gegen die Warenbahn geführt, so dass die oben über die erste Wickelwalze geführte Warenbahn auf den neuen Wickelkörper übergeleitet wird. Weiterhin ist unterhalb der Warenbahn eine Einrichtung vorgesehen, mit deren Hilfe das abgeschnittene Ende der Warenbahn um den neuen Wickelkörper gelegt wird. Der hierfür erforderliche Mechanismus ist relativ aufwendig, ohne dass dadurch ein sicheres und gutes Anwickeln gewährleistet wird.In this known device, a new bobbin is guided from above against the web, so that the guided above the first winding roller web is transferred to the new bobbin. Furthermore, a device is provided below the web, by means of which the cut end of the web is placed around the new bobbin. The mechanism required for this is relatively expensive, without thereby ensuring a safe and good Anwickeln.

Die EP-A-0 853 060 offenbart eine weitere Vorrichtung zum Wickeln einer Warenbahn mit einer ersten Wickelwalze, einer zweiten Wickelwalze, einer Schneideinrichtung sowie einer Einrichtung zum Zuführen eines neuen Wickelkörpers.EP-A-0 853 060 discloses another apparatus for winding a web having a first winding roll, a second winding roll, a cutter and means for feeding a new package.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Wickeln einer Warenbahn der eingangs genannten Art insbesondere hinsichtlich eines zuverlässigeren Anwickelverhaltens zu verbessern.The invention is therefore based on the object to improve a device for winding a web of the type mentioned in particular with regard to a more reliable Anwickelverhaltens.

Zum Greifen eines neuen Wickelkörpers 4 weist die Zuführeinrichtung zwei als Pinolen 3b ausgebildete Haltemittel auf, die gemäß Fig.7 seitlich in den Wickelkörper 4 einführbar sind. Über einen lediglich schematisch angedeuteten Antrieb 10 können die Pinolen und damit der Wickelkörper 4 angetrieben werden.For gripping a new winding body 4, the feeding device has two holding means embodied as sleeves 3 b, which, according to FIG. 7, can be inserted laterally into the winding body 4. About a merely schematically indicated drive 10, the sleeves and thus the winding body 4 can be driven.

Im folgenden wird die Betriebsweise der Wickelvorrichtung anhand der Fig.1 und 7 näher erläutert:

  • In der Wickelstellung gemäß Fig.1 wird die Warenbahn 5 über eine Umlenkwalze 11 der ersten Wickelwalze 1 zugeführt. Die von unten um die erste Wickelwalze 1 geführte Warenbahn wird auf den Wickelkörper bzw. den sich bildenden Warenwickel übergeleitet. Der sich bildende Warenwickel wird über die erste und vor allem auch über die zweite Wickelwalze 2 gestützt. Am Anfang der Wickelphase ist der Wickelkörper 4 seitlich durch die Haltemittel 3b geführt. Durch einen eigenen Antrieb des Wickelkörpers läßt sich der Wickelvorgang und insbesondere die Wickelhärte gezielt steuern.
The mode of operation of the winding device is explained in more detail below with reference to FIGS. 1 and 7:
  • In the winding position according to Figure 1, the web 5 is fed via a guide roller 11 of the first winding roller 1. The guided from below to the first winding roller 1 web is transferred to the winding body or the forming goods winding. The forming goods roll is supported on the first and above all on the second winding roller 2. At the beginning of the winding phase, the winding body 4 is guided laterally by the holding means 3b. By a separate drive of the bobbin, the winding process and in particular the winding hardness can be controlled specifically.

Mit zunehmenden Durchmesser des Warenwickels 6 wird dann die Führung des Warenwickels durch Führungsschienen 12 übernommen, indem die Enden des Wickelkörpers mit den Führungsschienen in Kontakt kommen. Die Haltemittel 3b werden dann seitlich abgezogen und in eine Warteposition gebracht.With increasing diameter of the fabric wrap 6, the leadership of the fabric roll is then taken over by guide rails 12 by the ends of the winding body come into contact with the guide rails. The holding means 3b are then withdrawn laterally and placed in a waiting position.

Die Umfangsgeschwindigkeit der ersten Wickelwalze 1 entspricht der Geschwindigkeit der Warenbahn in der Behandlungsvorrichtung. Die Umfangsgeschwindigkeit der zweiten Wickelwalze kann, sofern sie mit einem Einzelantrieb ausgerüstet ist, mit Vor- oder Nacheilung angetrieben werden, um so auf die Wickelfestigkeit Einfluß zu nehmen.The peripheral speed of the first winding roller 1 corresponds to the speed of the web in the treatment device. The peripheral speed of the second winding roller can, if it is equipped with a single drive, are driven with a lead or lag, so as to influence the winding resistance.

Wenn der Warenwickel 6 den gewünschen Durchmesser erreicht hat, wird er mit Hilfe einer Verstelleinrichtung 13 zusammen mit der zweiten Wickelwalze 2 abgeschwenkt, wie das aus Fig.2 zu ersehen ist. Ein neuer Wickelkörper 4 wird mit Hilfe der Zuführeinrichtung 3 aus dem Magazin 9 von unten gegen die Warenbahn 5 geführt, so daß die von unten um die erste Wickelwalze 1 geführte Warenbahn 5 auf den neuen Wickelkörper 4 übergeleitet wird und diesen teilweise umschlingt.When the fabric wrap 6 has reached the desired diameter, it is pivoted by means of an adjusting device 13 together with the second winding roller 2, as can be seen from Fig.2. A new bobbin 4 is guided by means of the feeder 3 from the magazine 9 from below against the web 5, so that the guided from below to the first winding roller 1 web 5 is transferred to the new bobbin 4 and this wraps around partially.

Dann wird die Gegenhaltevorrichtung 7 gemäß Fig.3 eingeschwenkt, wobei deren Tragarm so ausgerichtet ist, daß die Gegenhaltevorrichtung mit ihrem vorderen Kontaktbereich 7a als erstes mit der Warenbahn 5 in Kontakt kommt. Alsdann wird der Tragarm 7c gemäß Fig.4 in Position gedreht, wobei der vordere Kontaktbereich 7a der Gegenhaltevorrichtung in den von der ersten Wickelwalze 1 und dem neuen Wickelkörper 4 gebildeten, nach unten offenen Zwickel 16 weist, so daß sich der Umschlingungswinkel der Warenbahn 5 um den neuen Wickelkörper 4 vergrößert (siehe Fig.4).Then, the counter-holding device 7 is pivoted in accordance with Figure 3, wherein the support arm is oriented so that the counter-holding device comes with its front contact portion 7a first with the web 5 in contact. 4, the front contact region 7a of the counter holding device in the formed by the first winding roller 1 and the new bobbin 4, downwardly open gusset 16 has, so that the wrap angle of the web 5 to enlarged the new bobbin 4 (see Figure 4).

Der Schneidvorgang erfolgt unmittelbar danach innerhalb von Sekundenbruchteilen (siehe Fig.4 und 9), wobei die Einrichtung 8 zum Querschneiden der Warenbahn unmittelbar nach dem Schneidvorgang wieder in die Wartestellung gemäß den Fig.1 bis 4 gefahren wird.The cutting process takes place immediately thereafter within fractions of a second (see FIGS. 4 and 9), the device 8 for cross-cutting the material web being moved back into the waiting position according to FIGS. 1 to 4 immediately after the cutting process.

Die Warenbahn 5 ist in Fig.5 vor dem Schneidvorgang durch eine strichpunktierte Linie dargestellt. Die sich durch den Schneidvorgang ergebenden beiden Enden 5a bzw. 5b der Warenbahn sind gestrichelt dargestellt. Während das Ende 5b durch den Antrieb der zweiten Wickelwalze 2 auf den Warenwickel 6 fertig aufgewickelt wird, erfolgt mit dem anderen Ende 5a das Anwickeln des neuen Wickelkörpers 4. Die Drehrichtungen der ersten Wickelwalze 1 und des neuen Wickelkörpers 4 werden durch die Pfeile 14 und 15 angezeigt.The web 5 is shown in Figure 5 before the cutting process by a dashed line. The resulting by the cutting process two ends 5a and 5b of the web are shown in dashed lines. While the end 5b is wound up ready by the drive of the second winding roller 2 on the goods roll 6, takes place with the other end 5a, the winding of the new bobbin 4. The directions of rotation of the first winding roller 1 and the new bobbin 4 by the arrows 14 and 15th displayed.

Wie insbesondere aus Fig.5 zu ersehen ist, wird der neue Wickelkörper 4 mit der Warenbahn 5 mit Hilfe der Gegenhaltevorrichtung 7 bereits zu etwa drei Vierteln umschlungen. Um nun das Einführen des Endes 5a der Warenbahn in den zwischen der ersten Wickelwalze 1 und dem neuen Wickelkörper 4 gebildeten Zwickel 16 zu erleichtern, ist der vordere Kontaktbereich 7a der Gegenhaltevorrichtung als eine abgerundete, im Querschnitt etwa dreieckförmige Leiste ausgebildet. Der vordere Kontaktbereich ist zudem mit Düsen 17 versehen, die mit Druckgas beaufschlagbar sind. Durch eine entsprechende Druckluftbeaufschlagung nach dem Schneidvorgang wird das abgeschnittene Ende der Warenbahn in den Zwickel 16 geblasen, wodurch das Anwickeln erheblich unterstützt wird.As can be seen in particular from Figure 5, the new bobbin 4 is already wrapped with the web 5 by means of the counter-holding device 7 to about three quarters. In order to facilitate the insertion of the end 5a of the fabric web in the gusset 16 formed between the first winding roller 1 and the new winding body 4, the front contact region 7a of the counter-holding device is formed as a rounded, approximately triangular in cross-section bar. The front contact area is also provided with nozzles 17 which are acted upon by compressed gas. By an appropriate Druckluftbeaufschlagung after the cutting process, the cut end of the web is blown into the gusset 16, whereby the Anwickeln is significantly supported.

Nach erfolgtem Anwickeln wird auch die Gegenhaltevorrichtung 7 wieder in ihre Ruhestellung gedreht, während gleichzeitig der fertige Warenwickel 6 in eine nicht näher dargestellte Vorrichtung abgelegt wird. Anschließend wird die Wickelwalze 2 mit den Führungsschienen 12 in eine Zwischenposition eingeschwenkt, um das Anwickeln (siehe Fig.6) fortzuführen. Sobald ein vorgegebener Durchmesser des neu angewickelten Warenwickels erreicht ist, wird die Wickelwalze 2 wieder in die Wickelposition gemäß Fig.1 geschwenkt.After the initial winding and the counter-holding device 7 is again rotated to its rest position, while the finished goods roll 6 is stored in a device not shown. Subsequently, the winding roller 2 is pivoted with the guide rails 12 in an intermediate position to continue the Anwickeln (see Figure 6). As soon as a predetermined diameter of the newly wound goods roll is reached, the winding roller 2 is pivoted again into the winding position according to FIG.

Die beiden Wickelwalzen 1, 2, die Gegenhaltevorrichtung 7 und die Einrichtung 8 zum Querschneiden der Warenbahn sind für eine maximale Arbeitsbreite ausgelegt. Lediglich die als Pinolen ausgebildeten Haltemittel, die Führungsschienen 12 und das Magazin 9 müssen auf eventuell geringere Arbeitsbereiten einstellbar sein.The two winding rollers 1, 2, the counter-holding device 7 and the device 8 for cross-cutting the web are designed for a maximum working width. Only trained as quills holding means, the guide rails 12 and the magazine 9 must be adjustable to possibly lower working.

Die Einrichtung 8 zum Querschneiden der Warenbahn ist üblicherweise mit rotierenden Schneidmessern versehen (siehe Fig.5). Es sind in diesem Zusammenhang jedoch auch feststehende Messer denkbar.The device 8 for cross-cutting the web is usually provided with rotating cutting blades (see Figure 5). However, fixed knives are also conceivable in this connection.

Ein weiteres Ausführungsbeispiel ist in den Fig.8 und 9 dargestellt. Es unterscheidet sich vom ersten Ausführungsbeispiel im wesentlichen nur durch die Einrichtung 3' zum Zuführen eines neuen Wickelkörpers 4. Anstelle der Hubvorrichtung 3a gemäß dem ersten Ausführungsbeispiel ist hier ein Schwenkarm 3'a vorgesehen, der eine etwas kompaktere Bauweise ermöglicht. Während des Wickelvorgangs wird mit dem Schwenkarm 3'a der neue Wickelkörper 4 aus dem Magazin 9 genommen und in Wartestellung gemäß Fig.8 gebracht.Another embodiment is shown in Figures 8 and 9. It differs from the first embodiment substantially only by the means 3 'for supplying a new bobbin 4. Instead of the lifting device 3a according to the first embodiment, a pivot arm 3'a is provided here, which allows a slightly more compact design. During the winding process, the new winding body 4 is removed from the magazine 9 with the swivel arm 3'a and brought into the waiting position according to FIG.

Wenn der Warenwickel 6 den gewünschten Durchmesser erreicht hat, wird dieser abgeschwenkt, so daß der in Wartestellung befindliche Wickelkörper 4 in die Wickelposition gemäß Fig.9 gedreht wird.If the goods roll 6 has reached the desired diameter, this is pivoted so that the bobbin 4 is in the waiting position is rotated to the winding position shown in Figure 9.

Die als Pinolen ausgebildeten Haltemittel 3'b sind als separate Einrichtung oberhalb der Warenbahn angeordnet und werden dann nach unten geschwenkt, um den in Wickelposition befindlichen Wickelkörper 4 aufzunehmen.The holding means 3'b designed as quills are arranged as a separate device above the material web and are then pivoted downwards to receive the winding body 4 located in the winding position.

Es erfolgt dann das Einschwenken der Gegenhaltevorrichtung 7, das Schneiden, das Anwickeln, das Zurückdrehen der Gegenhaltevorrichtung und das Ablegen des Warenwickels in der bereits oben bezüglich des ersten Ausführungsbeispieles gezeigten Art und Weise.There then takes place the pivoting of the counter-holding device 7, the cutting, the Anwickeln, the turning back of the counter-holding device and the depositing of the goods roll in the manner already shown above with respect to the first embodiment.

Beide Ausführungsbeispiele zeichnen sich durch ein verbessertes Anwickelverhalten aus.Both embodiments are characterized by an improved Anwickelverhalten.
