  • the invention relates to a winding device for winding a web to a winding roll, comprising a roller carrier having at least two driven roller receivers, which are displaceable between a winding position and a replacement position, a transfer device and a pressure device.
  • the passing of the material web from a finished Wikkelrolle on a roll core is known per se. There are several possibilities for this.

Simultaneously with the severing of the formed during the separation of the beginning of the material web is guided around the new winding tube and, optionally passed after passing through a nip under the further tapered material web, so that the material web holds itself on the roll core. In this case, preparation of the roll core, such as tacking, is not required. In many cases, such a preparation is not desirable, because you want to save costs.

The quality of the first winding layers is therefore the same for both winding directions. Care is taken at the beginning of the winding process to ensure that the bobbins are started practically the same in both winding directions.
  • Each separating device has a counter-holder on the opposite side of the material web.
  • the counter-holders are mirror-symmetrical to each other and arranged and adjustable to different tube diameter.
  • Such an anvil facilitates the severing of the material web. It forms, as it were, a beam on which the material web is sheared off by the separating device. This also applies if the separating device and the counter-holder, such as a pair of scissors, is not formed with contacting cutting edges.
  • the anvil When the anvil is brought to the web, then it prevents the web excessively evades and later forms wrinkles on the winding tube.

It thus creates a simple way the required space for movement of the separator, without giving up the function of the anvil for both winding directions.
  • the counter-holder has a lever arm which is pivotable on the carriage. This creates a greater freedom for the mobility of the carriage. If the carriage is to be moved, then you can pivot the counter-holder so that it does not collide with any additional components. The motion control is relatively easy.
  • an auxiliary arm is arranged on the lever arm, which is controlled relative to the lever arm pivotable and has a separating edge.
  • the auxiliary arm thus forms the actual functional element that is used to sever the material web.

  • the pressure device has a pressure slide, which is displaceable relative to the roller carrier, wherein the slides receiving the separating devices are displaceable relative to the pressure slide.

  • each counter-holder is associated with a deflection roller, which can be applied with the interposition of the material web behind the separation point to the new winding tube and forms a Fangnip.

Description

Die Erfindung betrifft eine Wickelvorrichtung zum Aufwickeln einer Materialbahn zu einer Wickelrolle, mit einem Rollenträger, der mindestens zwei angetriebene Rollenaufnahmen aufweist, die jeweils zwischen einer Wickelposition und einer Austauschposition verlagerbar sind, einer Überleitungseinrichtung und einer Andruckeinrichtung.The invention relates to a winding device for winding a web to a winding roll, comprising a roller carrier having at least two driven roller receivers, which are displaceable between a winding position and a replacement position, a transfer device and a pressure device.

Die Erfindung wird im folgenden anhand des Wickelns von Folien beschrieben. Dies ist der Hauptanwendungszweck. Auf die gleiche Weise sind aber auch andere Materialbahnen zu Wickelrollen aufwickelbar.The invention will be described below with reference to the winding of films. This is the main purpose. But in the same way, other webs are wound into bobbins.

In der Regel am Ende eines Herstellungsprozesses müssen Warenbahnen zu handhabbaren Wickelrollen aufgewickelt werden. Gelegentlich werden derartige Wickelrollen aber auch zum Zwischenspeichern der Materialbahn verwendet. Wickelrollen haben allerdings nur eine begrenzte Aufnahmefähigkeit, d.h. es ist ein Wechsel der Wickelrollen erforderlich, wenn eine vorbestimmte Länge der Materialbahn aufgewickelt worden ist. Ein derartiger Rollenwechsel bedingt entweder eine Unterbrechung in der Zufuhr der Materialbahn. In diesem Fall hat man genügend Zeit, um die Materialbahn zu durchtrennen, das Ende an der fertig gewickelten Wickelrolle festzulegen und den Anfang an einem neuen Rollenkern zu befestigen. Eine derartige Vorgehensweise ist jedoch dann praktisch nicht möglich, wenn die Materialbahn kontinuierlich zuläuft. Dies ist beispielsweise bei der Herstellung von Folien der Fall, die extrudiert werden. In diesem Fall muß man praktisch schlagartig die Materialbahn durchtrennen und den Anfang der Materialbahn auf einem neuen Rollenkern festlegen, so daß das Aufwickeln ohne Unterbrechung erfolgen kann.As a rule, at the end of a production process, webs must be wound into manageable bobbins. Occasionally, such bobbins but also used for caching the web. However, bobbins have only a limited capacity, ie it is a change of the bobbins required if a predetermined length of the web has been wound up. Such a roll change requires either an interruption in the supply of the material web. In this case, you have enough time to cut through the web, set the end of the finished wound reel and secure the beginning of a new roll core. However, such a procedure is not practically possible if the material web runs continuously. This is the case, for example, in the production of films which are extruded. In this case, it is necessary to cut through the material web practically abruptly and to fix the beginning of the material web on a new roll core, so that the winding can take place without interruption.

Das Überleiten der Materialbahn von einer fertigen Wikkelrolle auf einen Rollenkern ist an sich bekannt. Hierfür gibt es mehrere Möglichkeiten. Bei aufwendigeren Anordnungen erfolgt das Trennen der Materialbahn gleichzeitig über die gesamte Breite, so daß ein Schnitt gebildet wird, der im wesentlichen rechtwinklig zur Bahnlaufrichtung verläuft. Gleichzeitig mit dem Durchtrennen wird der beim Trennen gebildete Anfang der Materialbahn um die neue Wickelhülse herumgeleitet und, gegebenenfalls nach Durchlaufen eines Nips unter die weiter zulaufende Materialbahn geleitet, so daß die Materialbahn sich selbst auf dem Rollenkern festhält. In diesem Fall ist eine Vorbereitung des Rollenkerns, etwa ein Klebrigmachen, nicht erforderlich. In vielen Fällen ist eine derartige Vorbereitung auch gar nicht gewünscht, weil man Kosten sparen möchte. In einfacheren Überleitungseinrichtungen wird ein Schneidmesser quer zur Materialbahn verfahren. Da die Materialbahn dabei weiterläuft, entsteht im Endeffekt ein schräger Schnitt. Hierbei kann man den dabei entstehenden Zipfel an einer Seite der Materialbahn ausnutzen, um diesen an der neuen Wickelhülse zu befestigen. Allerdings bedingt eine derartige Vorgehensweise, daß die Materialbahn nicht gleichförmig aufgewickelt wird. Am Anfang des Aufwickelns entsteht vielmehr eine schraubenlinienförmig verlaufende Sprungstelle, die später unter Umständen zu unerwünschten Störungen führen kann.The passing of the material web from a finished Wikkelrolle on a roll core is known per se. There are several possibilities for this. In more complex arrangements, the separation of the material web is carried out simultaneously over the entire width, so that a cut is formed which extends substantially at right angles to the web running direction. Simultaneously with the severing of the formed during the separation of the beginning of the material web is guided around the new winding tube and, optionally passed after passing through a nip under the further tapered material web, so that the material web holds itself on the roll core. In this case, preparation of the roll core, such as tacking, is not required. In many cases, such a preparation is not desirable, because you want to save costs. In simpler transfer devices, a cutting blade is moved transversely to the material web. As the web continues to run, the result is an oblique cut. Here you can see the resulting Zipfel take advantage of one side of the material web to attach it to the new winding tube. However, such a procedure requires that the material web is not wound uniformly. At the beginning of winding rather a helical jump point, which may sometimes lead to unwanted disturbances.

Erschwerend kommt hinzu, daß man einige Materialbahnen so wickeln möchte, daß ihre Oberseite auf der Wickelrolle außen zu liegen kommt. Andere Materialbahnen müssen hingegen so gewickelt werden, daß ihre Oberseite nach innen weist. Der automatische Wechsel der Wickelrichtungen ist bisher auch mit einem relativ hohen Aufwand praktisch nicht möglich. Ein einfaches Umkehren des Wickelrollenantriebs reicht nicht aus, weil dann die Auflaufverhältnisse der Materialbahn auf die Wikkelrolle nicht mehr stimmen.To make matters worse, that you want to wrap some webs so that their top comes to rest on the winding roll outside. Other webs, however, must be wound so that their top faces inward. The automatic change of the winding directions is previously practically impossible even with a relatively high cost. A simple reversing the winding roller drive is not enough, because then the casserole conditions of the web on the Wikkelrolle no longer true.

DE-A-28 23 326 zeigt eine Wickelvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1.DE-A-28 23 326 shows a winding device having the features of the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, eine Wickelvorrichtung bei im wesentlichen gleich hoher Wickelqualität unabhängig von der Wickelrichtung betreiben zu können.The invention has for its object to be able to operate a winding device at substantially the same high winding quality regardless of the winding direction.

Diese Aufgabe wird bei einer Wickelvorrichtung der eingangs genannten Art dadurch gelöst, daß die Rollenaufnahmen in zwei unterschiedlichen Drehrichtungen antreibbar sind, daß ein erster Materialbahnpfad, an dessen Ende die Materialbahn in einer-ersten Richtung auf die Wickelrolle aufläuft, und ein zweiter Materialbahnpfad, an dessen Ende die Materialbahn in eine zweite Richtung auf die Wickelrolle aufläuft, vorgesehen sind, und daß die Überleitungseinrichtung eine erste Trenneinrichtung, die von einer ersten Seite her in die Materialbahn einfahrbar ist, und eine zweite Trenneinrichtung, die von einer zweiten Seite her in die Materialbahn einfahrbar ist, aufweist.This object is achieved in a winding device of the type mentioned above in that the roller mounts are driven in two different directions of rotation, that a first material web path, at the end of the material web runs in a first direction on the winding roll, and a second material web path, at the End of the web in a second direction runs onto the winding roll, are provided, and that the transfer device, a first separating device, which is retractable from a first side into the material web, and a second separating device, which is retractable from a second side in the web, has.

Mit einer derartigen Wickelvorrichtung läßt sich mit relativ geringem Aufwand eine Änderung der Wickelrichtung erreichen. Die Materialbahn muß lediglich von dem einen Materialbahnpfad in den andere Materialbahnpfad umgeleitet werden. Mit dem Ändern des Bahnverlaufs in der Wickelvorrichtung wird die Materialbahn so geleitet, daß sie in der richtigen Richtung auf die Wickelrolle aufläuft. Diese richtige Richtung ist in der Regel praktisch tangential. Man kann nun noch den Wickelrollenantrieb mit einer entsprechenden Steuerung kombinieren, die den Wickelrollenantrieb in Abhängigkeit vom Bahnverlauf in die richtige Richtung ansteuert. Alternativ dazu kann man auch vorsehen, daß ein Materialbahnpfad nur dann freigegeben wird, wenn auch der Wikkelrollenantrieb in die richtige Richtung erfolgt. Schließlich ist noch vorgesehen, daß man zwei Trenneinrichtungen hat, die von jeweils unterschiedlichen Seiten her in die Materialbahn einfahrbar sind, um diese zu durchtrennen. Damit ist unabhängig von der Wickelrichtung immer sichergestellt, daß man mit Hilfe der Trenneinrichtung die Materialbahn um die neu zu bewikkelnde Wickelhülse herumleiten kann, so daß auch die. Überleitung unabhängig von der Wickelrichtung immer mit der gewünschten hohen Qualität erfolgen kann, und zwar praktisch faltenfrei von der ersten wickellage an. Dabei kann man durch Verstellen von Funktionselementen an beiden Überleitungseinrichtungen eine Anpassung an unterschiedliche Wickelhülsendurchmesser in einem relativ großen Bereich erzielen.With such a winding device can be achieved with relatively little effort, a change in the winding direction. The material web only has to be diverted from one material web path into the other material web path. By changing the trajectory in the winding device, the web is directed so that it runs in the right direction on the winding roll. This right direction is usually practically tangential. You can now combine the winding roller drive with a corresponding control that controls the winding roller drive in response to the trajectory in the right direction. Alternatively, one can also provide that a material web path is only released when the Wikkelrollenantrieb is done in the right direction. Finally, it is provided that you have two separators that are retractable from different sides in the web to cut them. Thus, regardless of the winding direction is always ensured that you can use the separator to guide the web about the newly to be wound winding tube, so that the. Reconciliation regardless of the winding direction can always be done with the desired high quality, and virtually wrinkle-free from the first reel. In this case, by adjusting functional elements on both transfer devices, it is possible to achieve adaptation to different winding tube diameters in a relatively large range.

Hierbei sind die beiden Trenneinrichtungen spiegelsymmetrisch zueinander aufgebaut sind. Hierbei ist eine exakte Symmetrie nicht erforderlich. Kleinere Abweichungen, die beispielsweise konstruktiv bedingt sein können, sind ohne weiteres zulässig. Wenn die beiden Trenneinrichtungen im wesentlichen spiegelsymmetrisch zueinander aufgebaut sind, dann erfolgt das Trennen durch die beiden Trenneinrichtungen auf die gleiche Weise, und die Materialbahn wird unabhängig davon, welche Trenneinrichtung aktiv ist, auf die gleiche Weise um die neu zu bewickelnde Wickelhülse herumgeführt. Die Qualität der ersten Wickellagen ist also für beide Wickelrichtungen gleich. Es wird bereits zu Beginn des Wickelvorgangs darauf geachtet, daß die Wickelrollen bei beiden Wickelrichtungen praktisch gleich begonnen werden.Here, the two separation devices are mirror-symmetrical to each other are. In this case, an exact symmetry is not required. Minor deviations, which may be constructive, for example, are readily permitted. If the two separators are constructed substantially mirror-symmetrical to each other, then the separation by the two separators takes place in the same manner, and the material web is guided around the new to be wound winding tube in the same way, regardless of which separator is active. The quality of the first winding layers is therefore the same for both winding directions. Care is taken at the beginning of the winding process to ensure that the bobbins are started practically the same in both winding directions.

Jede Trenneinrichtung weist einen Gegenhalter auf der gegenüberliegenden Seite der Materialbahn auf. Auch die Gegenhalter sind zueinander spiegelsymmetrisch aufgebaut und angeordnet und auf unterschiedliche Hülsendurchmesser einstellbar. Ein derartiger Gegenhalter erleichtert das Durchtrennen der Materialbahn. Er bildet sozusagen einen Balken, an dem die Materialbahn durch die Trenneinrichtung abgeschert wird. Dies gilt auch dann, wenn die Trenneinrichtung und der Gegenhalter nicht, wie eine Schere, mit einander berührenden Schneidkanten ausgebildet ist. Wenn der Gegenhalter an die Materialbahn herangeführt wird, dann verhindert er, daß die Materialbahn zu stark ausweicht und später Falten auf der Wickelhülse bildet. Mit anderen Worten bewirkt er eine Spannung in der Materialbahn, die ausreicht, um die Materialbahn mit einem Schlagschnitt durchtrennen zu können und Anlegefalten zu Beginn des Wickelvorgangs zu verhindern.Each separating device has a counter-holder on the opposite side of the material web. The counter-holders are mirror-symmetrical to each other and arranged and adjustable to different tube diameter. Such an anvil facilitates the severing of the material web. It forms, as it were, a beam on which the material web is sheared off by the separating device. This also applies if the separating device and the counter-holder, such as a pair of scissors, is not formed with contacting cutting edges. When the anvil is brought to the web, then it prevents the web excessively evades and later forms wrinkles on the winding tube. In other words, it causes a tension in the material web, which is sufficient to sever the material web with a hitting cut and to prevent contact wrinkles at the beginning of the winding process.

Hierbei ist bevorzugt, daß der Gegenhalter einer Trenneinrichtung auf einem Schlitten angeordnet ist, der gegenüber einer Messereinheit der anderen Trenneinrichtung verlagerbar ist. Wenn man zwei Trenneinrichtungen verwenden möchte, stellt sich im Hinblick auf die Gegenhalter das Problem, daß nur ein beschränkter Platz zur Verfügung steht. Wenn man nun den Gegenhalter der einen Trenneinrichtung verlagerbar macht, dann kann man ihn aus dem Wirkungsbereich der anderen Trenneinrichtung herausbewegen, wenn diese Trenneinrichtung in Funktion gesetzt werden soll. Man schafft also auf einfache Weise den benötigten Bewegungsraum für die Trenneinrichtung, ohne die Funktion der Gegenhalter für beide Wickelrichtungen aufzugeben.It is preferred that the counter holder of a separating device is arranged on a carriage which is displaceable relative to a blade unit of the other separating device. If you want to use two separators, arises with regard to the counter-holder the problem that only a limited space is available. If you now makes the counter-holder of a separator displaceable, then you can move it out of the scope of the other separator, if this separator is to be put into operation. It thus creates a simple way the required space for movement of the separator, without giving up the function of the anvil for both winding directions.

Hierbei ist besonders bevorzugt, daß der Gegenhalter einen Hebelarm aufweist, der an dem Schlitten verschwenkbar ist. Hierbei schafft man einen größeren Freiraum für die Verfahrbarkeit des Schlittens. Wenn der Schlitten verfahren werden soll, dann kann man den Gegenhalter so verschwenken, daß er mit keinen zusätzlichen Bauteilen kollidiert. Die Bewegungssteuerung wird dadurch relativ einfach.It is particularly preferred that the counter-holder has a lever arm which is pivotable on the carriage. This creates a greater freedom for the mobility of the carriage. If the carriage is to be moved, then you can pivot the counter-holder so that it does not collide with any additional components. The motion control is relatively easy.

Hierbei ist besonders bevorzugt, daß an dem Hebelarm ein Hilfsarm angeordnet ist, der gegenüber dem Hebelarm gesteuert verschwenkbar ist und eine Trennkante aufweist. Der Hilfsarm bildet also das eigentliche Funktionselement, das zum Durchtrennen der Materialbahn verwendet wird. Die Trennkante muß, wie oben bereits erwähnt, nicht unbedingt nach Art einer Schere mit der Trenneinrichtung zusammenwirken. Es reicht aus, wenn sie die Materialbahn mit einer Spannung beaufschlagt, die ausreicht, damit die Trenneinrichtung einen Schlagschnitt ausführten kann.It is particularly preferred that an auxiliary arm is arranged on the lever arm, which is controlled relative to the lever arm pivotable and has a separating edge. The auxiliary arm thus forms the actual functional element that is used to sever the material web. As has already been mentioned above, the separating edge does not necessarily have to interact with the separating device in the manner of a pair of scissors. It is sufficient if they applied to the web with a voltage sufficient for the separator can perform a hitting cut.

Hierbei ist besonders bevorzugt, daß der Hilfsarm in eine Lage tangential zu einer Wickelhülse positionierbar ist, auf die die Materialbahn überzuleiten ist. Damit ist beim Trennen die freie Weglänge der Materialbahn, in die die Trenneinrichtung eintaucht, sehr kurz.It is particularly preferred that the auxiliary arm can be positioned in a position tangential to a winding tube to which the material web is to be transferred. This is very short when separating the free path of the material web, in which the separator dips.

Vorteilhafterweise wirkt jede Trenneinrichtung auf die gesamte Breite der Materialbahn gleichzeitig ein. Damit entsteht beim Durchtrennen ein im wesentlichen zur Laufrichtung rechtwinklinger Schnitt. Die nachfolgend aufgewickelte Materialbahn wird also über die gesamte Breite gleichmäßig gewickelt.Advantageously, each separating device acts on the entire width of the material web at the same time. This results in cutting a rechtwinklinger essentially to the direction cut when cutting. The subsequently wound material web is thus wound evenly over the entire width.

Vorzugsweise weist die Andruckeinrichtung einen Andruckschlitten auf, der gegenüber dem Rollenträger verlagerbar ist, wobei die die Trenneinrichtungen aufnehmenden Schlitten gegenüber dem Andruckschlitten verlagerbar sind. Durch einen verlagerbaren Andruckschlitten wird gewährleistet, daß sich der Durchmesser der Wikkelrollen vergrößern kann, ohne daß die Rollenaufnahmen bewegt werden müssen. Der Andruckschlitten sorgt dafür, daß die Andruckrolle immer mit dem nötigen Druck an der Wickelrolle anliegen kann, um der Wickelhärte einen vorbestimmten Verlauf zu geben. Die Trenneinrichtungen sind hingegen gegenüber dem Andruckschlitten verlagerbar, so daß sie beim Wickeln nicht stören.Preferably, the pressure device has a pressure slide, which is displaceable relative to the roller carrier, wherein the slides receiving the separating devices are displaceable relative to the pressure slide. By a movable Andruckschlitten ensures that the diameter of Wikkelrollen can increase without the role recordings must be moved. The Andruckschlitten ensures that the pressure roller can always rest with the necessary pressure on the winding roll to give the winding hardness a predetermined course. The separating devices, however, are displaceable relative to the pressure slide, so that they do not interfere with winding.

Vorzugsweise weist jede Trenneinrichtung eine in die Materialbahn einfahrbare Leitrolle auf, die an einem Träger angeordnet ist, wobei ein Messer gegenüber dem Träger verschwenkbar ist. Mit Hilfe der Leitrolle kann die Materialbahn, die noch auf die volle Wickelrolle aufläuft, um die leere Wickelhülse herumgeleitet werden, so daß die verbleibende Länge, die durch das Messer noch um die Wickelhülse herumgeführt werden muß, klein gehalten werden kann.Each separating device preferably has a guide roller which can be moved into the material web and which is arranged on a carrier, wherein a knife can be pivoted relative to the carrier. With the help of the guide roller, the web, which still runs on the full winding roll, are passed around the empty winding tube, so that the remaining length, through the knife still has to be guided around the winding tube, can be kept small.

Auch ist von Vorteil, daß jedem Gegenhalter eine Umlenkrolle zugeordnet ist, die unter Zwischenlage der Materialbahn hinter der Trennstelle an die neue Wickelhülse anlegbar ist und einen Fangnip bildet. Wenn das Messer die Materialbahn durchtrennt hat, dann wird der durch den Schnitt gebildete Anfang der Materialbahn praktisch unmittelbar nach dem Trennen in den Nip zwischen der Wickelhülse und der Umlenkrolle geleitet und von der nachfolgend zugeführten Materialbahn dort festgehalten. Nach wenigen Umdrehungen ist dann die Materialbahn durch ihre eigene Spannung so auf der Wikkelhülse festgehalten, daß keine zusätzlichen Haltemittel mehr erforderlich sind. Eine Präparation der Wikkelhülse, also ein klebrigmachen, ist dann nicht erforderlich.It is also advantageous that each counter-holder is associated with a deflection roller, which can be applied with the interposition of the material web behind the separation point to the new winding tube and forms a Fangnip. If the knife has severed the web, then the beginning of the web formed by the cut is passed almost immediately after separation into the nip between the winding tube and the guide roller and held there by the subsequently fed material web. After a few turns then the web is held by their own tension on the Wikkelhülse that no additional holding means are required. A preparation of the Wikkelhülse, so a sticky, is then not required.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher beschrieben. Hierin zeigen:

die gleichen Verfahrensstadien beim Wickeln entgegen dem Uhrzeigersinn.
The invention will be described below with reference to a preferred embodiment in conjunction with the drawings. Herein show:
Fig. 1
a winding device,
Fig. 2
different process stages when winding in a clockwise direction and
Fig. 3
the same process stages when winding counterclockwise.

Fig. 1 zeigt eine Wickelvorrichtung 1 mit einem Maschinengestell 2, in dem ein Rollenträger 3 angeordnet ist. Der Rollenträger 3 ist hier durch einen Kreis symbolisiert. Er weist zwei angetriebene Rollenaufnahmen 4, 5 auf, wobei die Antriebe der Rollenaufnahmen 4, 5 eine Wickelrolle 6 entweder im Uhrzeigersinn (wie dargestellt) oder entgegen dem Uhrzeigersinn antreiben können. Die Antriebe sind also umsteuerbar. Der Rollenträger 3 weist ebenfalls einen Antrieb 7 auf, der die beiden Rollenaufnahmen 4, 5 zwischen einer Wickelposition, in der die Rollenaufnahme 4 derzeit angeordnet ist, und einer Austauschposition, in der die Rollanaufnahme 5 angeordnet ist, verlagern kann. Eine relativ einfache Ausführungsform sieht vor, daß die Rollenaufnahmen 4, 5 an Armen oder Platten angeordnet sind, die verdrehbar sind, so daß die Rollenaufnahmen 4, 5 Schwenkbewegungen ausführen, die durch die Kreislinie des Rollenträgers 3 dargestellt sind. Es ist aber auch möglich, daß die Rollenaufnähmen 4, 5 linear oder auf andere Weise verlagert werden.Fig. 1 shows a winding device 1 with a machine frame 2, in which a roller carrier 3 is arranged. The roller carrier 3 is symbolized here by a circle. It has two driven roller seats 4, 5 on, wherein the drives of the roller seats 4, 5 can drive a winding roller 6 either clockwise (as shown) or counterclockwise. The drives are therefore reversible. The roller carrier 3 also has a drive 7, which can shift the two roller seats 4, 5 between a winding position in which the roller holder 4 is currently arranged, and a replacement position in which the Rollanaufnahme 5 is arranged. A relatively simple embodiment provides that the roller seats 4, 5 are arranged on arms or plates which are rotatable, so that the roller seats 4, 5 perform pivotal movements, which are represented by the circular line of the roller carrier 3. However, it is also possible that the roller cushions 4, 5 are displaced linearly or in another way.

Eine Andruckwalze 8 ist auf einem Andruckschlitten 9 angeordnet. Der Andruckschlitten 9 wird mit Hilfe eines Antriebs 10 beim Wickeln immer so positioniert, daß die Andruckwalze 8 mit einem vorbestimmten Druck gegen eine Wickelrolle oder eine Wickelhülse 11 gedrückt wird, die sich in der Rollenaufnahme 4 befindet, die in der Wikkelposition angeordnet ist. Mit zunehmendem Durchmesser der Wickelrolle in der Wickelposition wird der Schlitten 9 verlagert, also von der Rollenaufnahme 4 weggefahren, so daß die Andruckwalze 8 immer einen gleichförmigen Druck auf die Wickelrolle ausüben kann, um die Wickelhärte günstig zu beeinflussen.A pressure roller 8 is arranged on a pressure slide 9. The Andruckschlitten 9 is always positioned by means of a drive 10 during winding, that the pressure roller 8 is pressed at a predetermined pressure against a winding roll or a winding tube 11 which is located in the roller seat 4, which is arranged in the Wikkelposition. With increasing diameter of the winding roll in the winding position of the carriage 9 is displaced, that is moved away from the roll holder 4, so that the pressure roller 8 can always exert a uniform pressure on the winding roll to influence the winding hardness low.

Am Andruckschlitten 9 sind zwei stationäre Umlenkrollen 12, 13 angeordnet, wobei sich "stationär" auf die Anbringung am Andruckschlitten 9 bezieht.At the pressure slide 9, two stationary pulleys 12, 13 are arranged, with "stationary" refers to the attachment to the pressure slide 9.

Auf dem Andruckschlitten 9 sind ferner zwei Schlitten 14a, 14b angeordnet, die gegenüber dem Andruckschlitten 9 verlagerbar sind, und zwar parallel zu der Richtung, in der der Andruckschlitten 9 von der Rollenaufnahme 4 weg bewegt werden kann. Die beiden Schlitten 14a, 14b sind im wesentlichen spiegelsymmetrisch zueinander ausgebildet, so daß einander entsprechende Teile mit den gleichen Bezugszeichen versehen werden, die für den oberen Schlitten den Zusatz "a" und für den unteren Schlitten den Zusatz "b" tragen.On the Andruckschlitten 9 two carriages 14a, 14b are further arranged, which are displaceable relative to the Andruckschlitten 9, parallel to the direction in which the Andruckschlitten 9 can be moved away from the roller seat 4. The two slides 14a, 14b are formed substantially mirror-symmetrical to each other, so that corresponding parts are provided with the same reference numerals that carry the addition "a" for the upper slide and the addition "b" for the lower slide.

Jeder Schlitten 14a, 14b weist zunächst einen Antrieb 15a, 15b auf, mit dem er gegenüber dem Andruckschlitten 9 bewegbar ist. Der Schlitten 14a, 14b weist darüber hinaus ein zweites Umlenkrollenpaar 16a, 17a; 16b, 17b auf, wobei die Umlenkrollen 16a, 17a und 16b, 17b an einem Hebel 18a, 18b mit einem Antrieb 19a, 19b angeordnet sind. Der Antrieb 19a, 19b kann den Hebel 18a, 18b verschwenken.Each carriage 14a, 14b initially has a drive 15a, 15b, with which it is movable relative to the pressure slide 9. The carriage 14a, 14b also has a second deflection roller pair 16a, 17a; 16b, 17b, wherein the deflection rollers 16a, 17a and 16b, 17b are arranged on a lever 18a, 18b with a drive 19a, 19b. The drive 19a, 19b can pivot the lever 18a, 18b.

Ferner ist an jedem Schlitten 14a, 14b ein Gegenhalter 20a, 20b angeordnet. Der Gegenhalter 20 weist einen Hebelarm 21 (nur für den Gegenhalter 20a erläutert) auf, an dem ein Hilfsarm 22 angeordnet ist. Der Hebelarm 21 ist mit Hilfe eines Antriebs 23 gegenüber dem Schlitten 14a verschwenkbar. Der Hilfsarm 22 ist mit Hilfe eines Antriebs 24 gegenüber dem Hebelarm 21 verschwenkbar. Am Hilfsarm 22 ist eine Trennkante 25 angeordnet. Der Hilfsarm 22 kann, wie dies für den Gegenhalter 20b dargestellt ist, so positioniert werden, daß er im wesentlichen tangential zur Wickelhülse 11 liegt, die in der wickelposition 4 angeordnet ist. Hierzu wird der Hebelarm 21 gegenüber dem Schlitten 14 und der Hilfsarm 22 gegenüber dem Hebelarm 21 verschwenkt. Gleichzeitig wird der entsprechende Hebel 18, der dem Gegenhalter 20 zugeordnet ist, so verschwenkt, daß die Umlenkrolle 17 unter Zwischenlage der aufzuwickelnden Materialbahn 26 in Anlage an die Wickelhülse 11 kommt.Further, a counter-holder 20a, 20b is arranged on each carriage 14a, 14b. The counter-holder 20 has a lever arm 21 (explained only for the counter-holder 20 a), on which an auxiliary arm 22 is arranged. The lever arm 21 is pivotable by means of a drive 23 relative to the carriage 14a. The auxiliary arm 22 is pivotable by means of a drive 24 relative to the lever arm 21. At the auxiliary arm 22, a separating edge 25 is arranged. The auxiliary arm 22 can, as shown for the counter-holder 20 b, be positioned so that it is substantially tangential to the winding tube 11, which is arranged in the winding position 4. For this purpose, the lever arm 21 is pivoted relative to the carriage 14 and the auxiliary arm 22 relative to the lever arm 21. At the same time, the corresponding lever 18, the counterholder 20 is assigned, pivoted so that the guide roller 17 comes with the interposition of the wound material web 26 in abutment with the winding tube 11.

Am Andruckschlitten 9 sind ferner zwei Trenneinrichtungen 27a, 27b angeordnet, die ebenfalls spiegelsymmetrisch zueinander ausgebildet sind. Aus Gründen der Übersichtlichkeit wird lediglich die untere Trenneinrichtung 27b näher erläutert. Diese weist einen Antrieb 28 auf, mit dem ein Hebel 29 gegenüber dem Andruckschlitten 9 verschwenkbar ist. Am Hebel 29 ist eine Umlenkrolle 30 angeordnet, die in die Materialbahn eintauchbar ist, und zwar dergestalt, daß sie die Materialbahn 26 kurz hinter der Wickelhülse 11 berührt. Ferner ist an jeder Trenneinrichtung 27a, 27b ein Messer 31 angeordnet, das einen gebogenen Träger 32 aufweist. Das Messer ist mit Hilfe eines Antriebs 33 gegenüber dem Hebel 29 verschwenkbar. Das Messer 31 geht über die gesamte Breite der Wickelvorrichtung 1 durch, ist also in der Lage, die Materialbahn 26 mit einem im wesentlichen rechtwinklig zur Laufrichtung verlaufende Schnitt zu durchtrennen, also einen sogenannten Schlagschnitt auszuführen. Durch die Träger 32 wird die Materialbahn dann um die Wickelhülse 11 herumgeführt. Die Trenneinrichtung 27a, 27b bildet zusammen mit dem Gegenhalter 20b, 20a auf der gegenüberliegenden Seite der Materialbahn 26 eine Überleitungseinrichtung.On Andruckschlitten 9 two separators 27a, 27b are further arranged, which are also formed mirror-symmetrical to each other. For reasons of clarity, only the lower separating device 27b will be explained in more detail. This has a drive 28, with which a lever 29 relative to the pressure slide 9 is pivotable. On the lever 29, a guide roller 30 is arranged, which is immersed in the material web, in such a way that it contacts the web 26 just behind the winding tube 11. Furthermore, a knife 31, which has a curved support 32, is arranged on each separating device 27a, 27b. The knife is pivotable by means of a drive 33 relative to the lever 29. The knife 31 extends over the entire width of the winding device 1, so it is able to cut through the material web 26 with a substantially perpendicular to the running direction section, so perform a so-called impact cut. By the carrier 32, the material web is then guided around the winding tube 11. The separating device 27a, 27b forms, together with the counter-holder 20b, 20a on the opposite side of the material web 26, a transfer device.

Wie aus Fig. 1 zu erkennen ist, ist die Materialbahn 26 im Moment des Durchtrennens über die unteren Umlenkrollen 16b, 17b geführt und verläuft dann im Uhrzeigersinn um die Wickelhülse 11 herum. Danach wird sie über die Umlenkrolle 30 der oberen Trenneinrichtung 27a geführt, während von unten der Hilfsarm 22 des Gegenhalters 20b gegenüber der Materialbahn 26 positioniert worden ist.As can be seen from Fig. 1, the material web 26 at the moment of cutting over the lower pulleys 16b, 17b out and then runs in a clockwise direction around the winding tube 11 around. Thereafter, it is guided over the deflection roller 30 of the upper separating device 27a, while the auxiliary arm 22 of the counter-holder 20b has been positioned opposite the material web 26 from below.

Hierbei ist es allerdings nicht notwendig, daß die Stirnseite des Hilfsarmes, also die Trennkante 25, die Materialbahn 26 berührt. Dabei existiert nur eine relativ kurze freie Weglänge zwischen der Wickelhülse 11 und der Umlenkrolle 30. Wenn das Messer 31 von der oberen Trenneinrichtung 27 in die Materialbahn 26 eingefahren wird, dann wird die Materialbahn 26 durchtrennt, solange eine genügend große Spannung zwischen der Wikkelhülse 11 und der Umlenkrolle 30 aufrechterhalten werden kann. Bei Materialbahnen 26, die nachgiebiger sind, beispielsweise bei bestimmten Kunststoffolien, wird die Materialbahn beim Eintauchen des Messers 31 gegen die Trennkante 25 des Gegenhalters 20b gedrückt. Dies verkürzt zum einen die freie Bahnlänge weiter, weil nun nur noch eine Bahnlänge zwischen der Wickelhülse 11 und der Trennkante 25 zur Verfügung steht. Gleichzeitig ermöglicht die Trennkante 25 ein Abscheren der Materialbahn 26.However, it is not necessary that the end face of the auxiliary arm, so the separating edge 25, the web 26 touches. In this case, there is only a relatively short free path between the winding tube 11 and the guide roller 30. When the knife 31 is retracted by the upper separator 27 into the web 26, then the web 26 is severed, as long as a sufficiently large voltage between the Wikkelhülse 11 and the deflection roller 30 can be maintained. For material webs 26, which are more flexible, for example in certain plastic films, the material web is pressed during dipping of the blade 31 against the separating edge 25 of the counter-holder 20 b. On the one hand, this further shortens the free web length, because now only one web length is available between the winding tube 11 and the separating edge 25. At the same time, the separating edge 25 enables a shearing off of the material web 26.

Der gebogene Träger 32 leitet nun die abgeschnittene Materialbahn, genauer gesagt, deren Anfang, um die Wikkelhülse 11 herum. Der Anfang gelangt dann in den Nip zwischen der Umlenkrolle 17b und der Wickelhülse 11, und zwar gelangt der Anfang dabei unter die nachgeforderte Materialbahn, die um die Umlenkrolle 17b läuft. Die Materialbahn 26 wird also gefangen und durch nachfolgende Materialbahnlagen auf der Wickelhülse 11 festgehalten.The curved support 32 now passes the cut material web, more precisely, its beginning, around the winding sleeve 11 around. The beginning then passes into the nip between the guide roller 17b and the winding tube 11, and indeed the beginning passes under the demanded material web, which runs around the guide roller 17b. The material web 26 is thus caught and held by subsequent material web layers on the winding tube 11.

Die Axbeitsweise der Wickelvorrichtung 1 soll nun anhand der Fig. 2 und 3 näher beschrieben werden.The Axbei way of the winding device 1 will now be described with reference to FIGS. 2 and 3 in more detail.

Fig. 2a zeigt einen Zustand, in dem die Wickelrolle 6, die sich um Uhrzeigersinn dreht, fast fertig gewickelt worden ist. Die Andruckwalze 8 auf dem Andruckschlitten 9 ist beim Wickeln permanent in Kontakt mit der Wickelrolle 6.Fig. 2a shows a state in which the winding roller 6, which rotates clockwise, has been wound almost finished. The pressure roller 8 on the pressure slide 9 is permanently in contact with the winding roller 6 during winding.

Wenn die Wickelrolle 6 fertig gewickelt ist, dann wird der Andruckschlitten 9 so weit zurückgefahren, daß die Andruckwalze 8 außer Kontakt mit der Wickelrolle 6 kommt. Der Rollenträger 3 wird verdreht, so daß die volle Wickelrolle 6 in die Austauschposition gelangt und eine neue Wickelhülse 11 in die Wickelposition. Dabei wird der Andruckschlitten 9 wieder auf die Wickelposition 4 zugefahren, so daß die Andruckwalze 8 an der neuen Wickelhülse 11 anliegt. Die Wickelrolle 6 wird weiter gedreht, so daß bei diesem Vorgang die Materialbahn 26 weiter aufgewickelt wird.When the winding roller 6 is finished wound, then the Andruckschlitten 9 is moved back so far that the pressure roller 8 comes out of contact with the winding roller 6. The roller carrier 3 is rotated, so that the full winding roller 6 enters the exchange position and a new winding tube 11 in the winding position. In this case, the Andruckschlitten 9 is fed back to the winding position 4, so that the pressure roller 8 abuts the new winding tube 11. The winding roller 6 is rotated further, so that in this process, the web 26 is further wound up.

Danach fährt der untere Schlitten 14b auf die Wickelhülse 11 zu, bis er an einen Anschlag 34 zur Anlage kommt. Gleichzeitig mit dieser Bewegung oder etwas später wird der Gegenhalter 20b so verschwenkt, wie dies in Fig. 1 dargestellt ist. Der Hebel 18b wird hochgeschwenkt, so daß die Umlenkrolle 17b an der Wickelhülse 11 anliegt. Damit ist die Situation erreicht, die in Fig. 1 dargestellt ist. Der oben geschilderte Trennvorgang kann dann erfolgen.Thereafter, the lower carriage 14b moves toward the winding tube 11 until it comes to rest against a stop 34. Simultaneously with this movement or a little later, the counter-holder 20b is pivoted as shown in Fig. 1. The lever 18b is pivoted up, so that the guide roller 17b rests against the winding tube 11. Thus, the situation is reached, which is shown in Fig. 1. The above-described separation process can then take place.

Aus Fig. 2 ist ersichtlich, daß die Materialbahn 26 in einem ersten Materialbahnpfad durch die Wickelvorrichtung 1 hindurchgeführt worden ist. Dieser erste Materialbahnpfad beinhaltet ein Berühren der Umlenkrolle 12, ein teilweises Umschlingen der Umlenkrolle 13 und ein Umschlingen der Umlenkrollen 16b, 17b. Die Materialbahn gelangt dann von unten an die Andruckwalze 8.From Fig. 2 it can be seen that the material web 26 has been passed through the winding device 1 in a first material web path. This first material web path includes contacting the deflection roller 12, partially looping around the deflection roller 13 and looping around the deflection rollers 16b, 17b. The material web then passes from below to the pressure roller. 8

Fig. 3 zeigt nun die Betriebsweise der Wickelvorrichtung 1, bei der die Wickelrolle 6 in die entgegengesetzte Richtung gedreht wird. Dementsprechend ist auch ein zweiter Materialbahnpfad für die Materialbahn 26 vorgesehen. Hierbei umschlingt die Materialbahn 26 die Umlenkrolle 12. Sie wird nun um die Umlenkrolle 17a geführt und gelangt dann von oben zur Andruckwalze 8.Fig. 3 now shows the operation of the winding device 1, wherein the winding roller 6 in the opposite Direction is turned. Accordingly, a second material web path for the material web 26 is provided. Here, the web 26 wraps around the guide roller 12. It is now guided around the guide roller 17a and then passes from above to the pressure roller. 8

Der Rollenwechsel erfolgt in ähnlicher Weise, wie dies im Zusammenhang mit Fig. 2 beschrieben worden ist. Wenn die Wickelrolle 6 voll ist, wird der Rollenträger 3 verdreht, so daß eine Wickelhülse 11 in die Wickelposition gelangt, während die Wickelrolle 6 sich dann in der Austauschposition befindet. Beim Bewegen des Rollenträgers 3 wird der Andruckschlitten 9 zweckmäßigerweise nach links verfahren, so daß die Andruckwalze 8 außer Kontakt mit der Wickelrolle 6 kommt.The roll change takes place in a similar manner as has been described in connection with FIG. 2. When the winding roller 6 is full, the roller carrier 3 is rotated so that a winding tube 11 enters the winding position, while the winding roller 6 is then in the exchange position. When moving the roller carrier 3, the pressure slide 9 is expediently moved to the left, so that the pressure roller 8 comes out of contact with the winding roller 6.

Zum Überleiten wird der obere Schlitten 14a an den Anschlag 24 gefahren, und der Gegenhalter 20a entgegen dem Uhrzeigersinn verschwenkt, so daß der Hilfsarm 22 tangential zur Wickelhülse 11 liegt. Wenn nun die Trenneinrichtung 27b mit ihrer Umlenkrolle 30b in die Materialbahn 26 eintaucht, dann kann das Messer 31b die Materialbahn 26 in dem kurzen Stück zwischen der Wikkelhülse 11 und der Umlenkrolle 30b durchtrennen, wobei zweckmäßigerweise die Schneidkante 25 des Gegenhalters 20a als zusätzliche Hilfe genutzt wird.For passing the upper carriage 14a is moved to the stop 24, and the counter-holder 20a is pivoted counterclockwise, so that the auxiliary arm 22 is tangent to the winding tube 11. Now, if the separator 27b dips with its guide roller 30b in the web 26, then the knife 31b can cut through the material web 26 in the short piece between the Wikkelhülse 11 and the guide roller 30b, expediently the cutting edge 25 of the counter-holder 20a is used as an additional help ,

Von der dargestellten Ausführungsform kann in vielerlei Hinsicht abgewichen werden.From the illustrated embodiment may be departed from in many ways.

Die linearen Bewegungen können vielfach durch Schwenkbewegungen ersetzt werden. Die Ausweichbewegungen des Gegenhalters 20 gegenüber der Trenneinrichtung 27 auf der anderen Seite der Materialbahn 26 kann auch auf andere Weise realisiert werden. Es ist jedoch zweckmäßig, wenn der Gegenhalter von der Wickelrolle 6 weggefahren wird, um eine Bewegung der anderen Trenneinrichtung 27 nicht zu behindern.The linear movements can often be replaced by pivoting movements. The evasive movements of the counter-holder 20 relative to the separating device 27 on the other side of the material web 26 can also be realized in other ways. However, it is appropriate When the counter-holder is moved away from the winding roller 6, so as not to hinder a movement of the other separating device 27.
