  • EP-A-0 093 301 also shows a generic double support roller roller and a generic method in which the two support rollers are likewise arranged at a considerable distance from one another. This is necessary because the feed device for winding cores is passed upwards from below through the gap between the two support rollers in order to start the winding process on a new winding core. It is also possible to add a third support roller to the two support rollers to connect and allow the feed device for the winding cores to reach through the gap between the second and the third support roller. But here, too, there are limited geometric relationships, so that the winding cores must not be less than a minimum diameter. Likewise, the winding of the winding material at the beginning of the diameter of the roll that is being formed and the use of the loading roller present difficulties at this time.
  • a carrier roller with three carrier rollers is known. Two of the support rollers are pivotally mounted about a common axis. At the beginning of the winding on a winding core, this or the winding material wound up into the roll is supported on these first two support rollers. In order to ensure the support in the support formed by the first two support rollers, a loading device is provided. By pivoting the two first support rollers, a support is formed between the first and the third support roller for the roller, the diameter of which continuously increases, the second support roller being arranged below this support. During the pivoting movement of the first two support rollers about their common axis, the roller is picked up by a pivoting device.
  • the roller As soon as the roller has reached its final diameter, it is moved out of the carrier roller roller with the swivel device beyond the third roller. While the roll is only supported on the third support roller, the first two support rollers swivel back to their starting position and take up a new winding core in their support. At the same time, a cutting device which grips between the second and the third roll cuts the material to be wound, which is subsequently wound onto the new winding core. With this known roller roller constant web tension conditions can not be guaranteed. A loading device that presses the winding core or the roll into the support formed by the support rollers only comes when the first windings for use. In addition, it has a negative effect that the winding core is initially only guided through the support rollers and does not have its own bearing which prevents play in the winding direction.

Abstract

A method for winding material 11 fed without interruption onto several winding cores 7, in particular on printing machines, makes use of a two-drum winder having two bearing drums 3, 4 and in the support 14 of which the winding material 11 is wound on a winding core 7 to form a roll 13 and is at the same time supported by a loading drum 8. The winding material 11 is firstly wound onto winding core 7 lying on the two bearing drums 3, 4 of the two-drum winder until the roll 13 has a weight which is sufficient for pressing against a supporting drum 21 of a Pope-type winder 20. The roll 13 is taken by a pivoting device 23 from the support 14 of the drum winder and is transferred by means of the second supporting drum 4 to the supporting drum 21 of the Pope-type winder 20 and is ready-wound there until the envisaged final diameter of the roll is achieved. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Aufwickeln von ohne Unterbrechung zugeführtem Wickelgut auf mehrere Wickelkerne, insbesondere an Druckmaschinen, mit einem zwei Tragwalzen aufweisenden Doppeltragwalzenroller, in dessen Auflager das Wickelgut auf einem Wickelkern zu einer Rolle aufgewickelt und dabei von einer Belastungswalze abgestützt wird. Die Erfindung bezieht sich auch auf einen Doppeltragwalzenroller zur Aufwicklung von ohne Unterbrechung zugeführtem Wickelgut auf mehrere Wickelkerne, mit zwei angetriebenen Tragwalzen, die ein Auflager für jede sich aus Wickelkern und Wickelgut bildende Rolle bilden, und einer vertikal über dem Auflager geführten Belastungswalze sowie mit einer Zuführeinrichtung für die Wickelkerne, einer Abführeinrichtung für die Rollen und einer Schneideinrichtung zum Durchtrennen des Wickelguts. Die Erfindung wird insbesondere am Ende von Druckmaschinen eingesetzt, die passergenau arbeiten müssen und bei denen es weiterhin auf ein kantengerades Aufwickeln ankommt.The invention relates to a method for winding wound material supplied without interruption onto a plurality of winding cores, in particular on printing machines, with a double carrier roller having two support rollers, in the support of which the material to be wound is wound on a winding core into a roll and is thereby supported by a loading roller. The invention also relates to a double carrier roller for winding wound material supplied without interruption on a plurality of winding cores, with two driven carrier rollers which form a support for each roll formed from the winding core and the material to be wound, and a load roller guided vertically above the support and with a feed device for the winding cores, a removal device for the rolls and a cutting device for cutting through the winding material.

Ein Verfahren der eingangs genannten Art und ein entsprechender Doppeltragwalzenroller ist aus der US-PS 2 989 262 bekannt. Zwei in horizontaler Richtung benachbart gelagerte angetriebene Tragwalzen bilden miteinander ein Auflager für einen Wickelkern, der wiederum in senkrechter Richtung von einer Belastungswalze im Auflager angepreßt wird. Das bahnförmig, kontinuierlich, d. h. ohne Unterbrechung, herangeführte Wickelgut wird nacheinander auf Wickelkerne aufgewickelt, wobei letztendlich entsprechende Rollen entstehen. Es ist auf der einen Seite des Doppeltragwalzenrollers eine Zuführeinrichtung für die Wickelkerne und auf der anderen Seite eine Abführeinrichtung für die fertigen Rollen vorgesehen. In dem Spalt zwischen den beiden Tragwalzen ist eine messerförmige Schneideinrichtung bewegbar gelagert, mit deren Hilfe die Bahn des Wickelguts von unten nach oben durchtrennt werden kann, um auf diese Art und Weise das Ende des Wickelguts auf einer Rolle und den Anfang des Wickelguts auf dem nächstfolgenden Wickelkern zu bilden. Die Anordnung der Schneideinrichtung in dem Spalt zwischen den beiden Tragwalzen erfordert einen gewissen Platz, so daß die Tragwalzen selbst mit ihren Achsen weiter voneinander entfernt angeordnet werden müssen, als dies an sich aufgrund ihrer Durchmesserausbildung erforderlich wäre. Dies wiederum führt dazu, daß die Wickelkern eine gewisse Mindestgröße in ihrem Durchmesser aufweisen müssen, so daß kleinere Wickelkerne nicht verwendet werden können. Ein solcher Tragwalzenroller erbringt jedoch eine gute Abstützung der Rolle auf den Tragwalzen. Durch die Belastungswalze ist auch bei kleinen Wickeldurchmessern eine nahezu konstante Bahnspannung einstellbar, da die Belastungswalze individuell be- und entlastet werden kann. Ein solcher Tragwalzenroller zeichnet sich auch dadurch aus, daß die Bahn des Wickelguts kantengenau aufgewickelt wird. Der Wechsel einer fertig gewickelten Rolle und der Einsatz eines neuen Wickelkerns bereiten jedoch gewisse Schwierigkeiten. Infolge der konstanten Bahnspannungsverhältnisse kann ein solcher Doppeltragwalzenroller jedoch nicht nur bei einfachen Aufgaben des flächenförmigen Einfärbens oder der Beschichtung von Wickelgut eingesetzt werden, sondern infolge der sehr guten Bahnspannungsverhältnisse auch bei Druckmaschinen.A method of the type mentioned at the beginning and a corresponding double carrier roller roller is known from US Pat.

Dies ist deshalb erforderlich, weil die Zuführeinrichtung für Wickelkerne von unten durch den Spalt zwischen den beiden Tragwalzen nach oben hindurchgeführt wird, um den Wickelvorgang auf einem neuen Wickelkern zu beginnen. Es ist auch möglich, den beiden Tragwalzen noch eine dritte Tragwalze nachzuschalten und die Zuführeinrichtung für die Wickelkerne durch den Spalt zwischen der zweiten und der dritten Tragwalze hindurchgreifen zu lassen. Aber auch hierbei ergeben sich eingeschränkte geometrische Verhältnisse, so daß die Wickelkerne einen Mindestdurchmesser nicht unterschreiten dürfen. Ebenso bereitet das Aufwickeln des Wickelguts zu Anfang des sich bildenden Durchmessers der Rolle und der Einsatz der Belastungswalze zu diesem Zeitpunkt Schwierigkeiten.EP-A-0 093 301 also shows a generic double support roller roller and a generic method in which the two support rollers are likewise arranged at a considerable distance from one another. This is necessary because the feed device for winding cores is passed upwards from below through the gap between the two support rollers in order to start the winding process on a new winding core. It is also possible to add a third support roller to the two support rollers to connect and allow the feed device for the winding cores to reach through the gap between the second and the third support roller. But here, too, there are limited geometric relationships, so that the winding cores must not be less than a minimum diameter. Likewise, the winding of the winding material at the beginning of the diameter of the roll that is being formed and the use of the loading roller present difficulties at this time.

Aus der DE-OS 19 29 570 ist ein Tragwalzenroller mit drei Tragwalzen bekannt. Zwei der Tragwalzen sind um eine gemeinsame Achse schwenkbar gelagert. Zu Beginn des Aufwickelns auf einen Wickelkern stützt sich dieser bzw. das zu der Rolle aufgewickelte Wickelgut auf diesen beiden ersten Tragwalzen ab. Um die Auflage in dem von den beiden ersten Tragwalzen gebildeten Auflager zu gewährleisten, ist eine Belastungsvorrichtung vorgesehen. Durch Verschwenken der beiden ersten Tragwalzen bildet sich für die Rolle, deren Durchmesser ständig anwächst ein Auflager zwischen der ersten und der dritten Tragwalze, wobei die zweite Tragwalze unterhalb dieses Auflagers angeordnet ist. Bei der Schwenkbewegung der beiden ersten Tragwalzen um ihre gemeinsame Achse wird die Rolle von einer Schwenkeinrichtung aufgenommen. Sobald die Rolle ihren Enddurchmesser erreicht hat, wird sie mit der Schwenkvorrichtung über die dritte Rolle hinweg aus dem Tragwalzenroller hinausbewegt. Während sich die Rolle hierbei nur auf der dritten Tragwalze abstützt, schwenken die ersten beiden Tragwalzen wieder in ihre Ausgangsposition zurück und nehmen dort einen neuen Wickelkern in ihrem Auflager auf. Gleichzeitig zerteilt eine zwischen der zweiten und der dritten Rolle hindurchgreifende Schneidevorrichtung das Wickelgut, welches im folgenden auf den neuen Wickelkern aufgewickelt wird. Bei diesem bekannten Tragwalzenroller können konstante Bahnspannungsverhältnisse nicht gewährleistet werden. Eine Belastungsvorrichtung, die den Wickelkern bzw. die Rolle in das von den Tragwalzen gebildete Auflager drückt, kommt nur beim Aufbringen der ersten Wicklungen zur Anwendung. Außerdem macht sich negativ bemerkbar, daß der Wickelkern anfänglich nur durch die Tragwalzen geführt wird und keine eigene ein Spiel in Aufwickelrichtung vermeidende Lagerung besitzt.From DE-OS 19 29 570 a carrier roller with three carrier rollers is known. Two of the support rollers are pivotally mounted about a common axis. At the beginning of the winding on a winding core, this or the winding material wound up into the roll is supported on these first two support rollers. In order to ensure the support in the support formed by the first two support rollers, a loading device is provided. By pivoting the two first support rollers, a support is formed between the first and the third support roller for the roller, the diameter of which continuously increases, the second support roller being arranged below this support. During the pivoting movement of the first two support rollers about their common axis, the roller is picked up by a pivoting device. As soon as the roller has reached its final diameter, it is moved out of the carrier roller roller with the swivel device beyond the third roller. While the roll is only supported on the third support roller, the first two support rollers swivel back to their starting position and take up a new winding core in their support. At the same time, a cutting device which grips between the second and the third roll cuts the material to be wound, which is subsequently wound onto the new winding core. With this known roller roller constant web tension conditions can not be guaranteed. A loading device that presses the winding core or the roll into the support formed by the support rollers only comes when the first windings for use. In addition, it has a negative effect that the winding core is initially only guided through the support rollers and does not have its own bearing which prevents play in the winding direction.

Andererseits sind sogenannte Pope-Roller bekannt, die im wesentlichen aus einer ortsfest gelagerten,
angetriebenen Abstützwalze und
einer Schwenkeinrichtung mit Aufnahmeteil für die Lager des Wickelkerns bestehen. Dabei wird also die sich bildende Rolle nicht auf zwei Tragwalzen wie bei einem Doppeltragwalzenroller, sondern angelehnt an die Abstützwalze während des Aufwickelvorgangs geführt, wobei sich in der Regel nur ein Teil der Gewichtskraft der Rolle auf der Abstützwalze abstützt. Die Schwenkvorrichtung ist um eine neben der Achse der Abstützwalze gelagerte Schwenkachse schwenkbar und dient dazu, eine fertige Rolle auszuheben und abzuführen. Solche Pope-Roller werden im wesentlichen in der Papierindustrie eingesetzt, und zwar bei der Herstellung des Papiers und seiner Weiterverarbeitung, z. B. wenn bahnförmiges Material eingefärbt, beschichtet, kaschiert oder in ähnlicher Weise behandelt werden muß, wenn es also auf eine passergenaue Bearbeitung nicht ankommt. Der große Vorteil dieser Gattung von Aufwickeleinrichtungen besteht in dem problemlosen Wechsel zwischen Rolle und neuem Wickelkern, ohne daß es erforderlich ist, die Zufuhr des Wickelguts zu unterbrechen. Jedoch treten in Verbindung mit Druckmaschinen, die passergenau arbeiten müssen, eine Reihe schwerwiegender Nachteile auf. So lassen sich die Spannungsverhältnisse der Bahn-des Wickelguts nur schwierig unter Kontrolle bringen. Auch die Abstützung und Anpressung der Rolle auf der Abstützwalze ist schlecht und unkontrolliert, insbesondere bei kleinen Wickelkerndurchmessern, etwa in der Größenordnung von 100 mm und bei großen Arbeitsbreiten, beispielsweise in einer Größenordnung von 2,5 m und größer. Bei einer derartigen Bahn des Wickelguts spielen auch die Durchbiegungsverhältnisse am Wickelkern bereits eine erhebliche Rolle und es entstehen während des Aufwickelns, insbesondere bei kleinen Durchmesser, nach rückwärts, also in die stromaufliegende Druckmaschine hineinreichend Bahnspannungsstöße, die sich bis zum Auftreten von Registerfehlern in der Druckmaschine auswirken können. Außerdem läßt sich oft das Auftreten von Quetschfalten zu Beginn einer Rolle schwerlich vermeiden; deshalb müssen Wickelkerne mit prinzipiell größerem Durchmesser als bei einem Doppeltragwalzenroller eingesetzt werden. Zu Anfang eines Aufwickelvorgangs herrschen wechselnde Bahnspannungsverhältnisse. Die Bahnspannung ist bis in den Bereich großer Rollendurchmesser hinein weniger gut kontrollierbar.
On the other hand, so-called Pope-Rollers are known, which essentially consist of a stationary,
driven support roller and
a swivel device with receiving part for the bearings of the winding core. Thus, the roll forming is not guided on two support rollers as in a double support roller, but based on the support roller during the winding process, with only a part of the weight of the roller generally being supported on the support roller. The swivel device can be swiveled about a swivel axis mounted next to the axis of the support roller and serves to lift and remove a finished roll. Such Pope-Roller are mainly used in the paper industry, specifically in the manufacture of paper and its further processing, e.g. B. if sheet-like material has to be colored, coated, laminated or treated in a similar way, so if it is not a question of accurate registration. The great advantage of this type of winding device is the easy change between reel and new winding core, without it being necessary to interrupt the supply of the winding material. However, there are a number of serious disadvantages associated with printing presses that have to work in registration. It is difficult to control the tension of the web of the winding material. The support and pressure of the roll on the support roller is poor and uncontrolled, especially with small winding core diameters, for example in the order of 100 mm and with large ones Working widths, for example in the order of 2.5 m and larger. With such a path of the material to be wound, the deflection conditions at the winding core already play a significant role, and during the winding, especially with a small diameter, backwards, that is, into the upstream printing press there are sufficient web tension surges which have an effect until register errors occur in the printing press can. In addition, it is often difficult to avoid the appearance of pinch folds at the beginning of a roll; That is why winding cores with a larger diameter than a double carrier roller have to be used. At the beginning of a winding process, changing web tension conditions prevail. The web tension is less easy to control up to the area of large roll diameters.

Der Erfindung liegt die Aufgabe zugrunde, ausgehend von einem Doppel-Tragwalzenroller der eingangs genannten Art mit nahe beieinander angeordneten Tragwalzen ein Verfahren und einen Doppeltragwalzenroller aufzuzeigen, mit dem es möglich ist, weitgehend konstante Bahnspannungsverhältnisse zu realisieren, automatisch, d. h. ohne Unterbrechung des zugeführten Wickelguts, zu arbeiten, dabei einen problemlosen Wechsel zu ermöglichen und kantengenau aufzuwickeln.The invention is based on the object, starting from a double carrier roller of the type mentioned with carrier rollers arranged close to one another, to show a method and a double carrier roller with which it is possible to achieve largely constant web tension conditions, automatically, i. H. to work without interruption of the supplied winding material, to enable a problem-free change and to wind up with exact edges.

Erfindungsgemäß wird dies bei dem Verfahren der eingangs beschriebenen Art dadurch erreicht, daß das Wickelgut zunächst auf einen auf den beiden Tragwalzen des Doppeltragwalzenrollers aufliegenden Wickelkern solange aufgewickelt wird, bis die Rolle ein ausreichendes Gewicht für die Anpressung an einer Abstützwalze, die der ortsfest gelagerte, angetriebene Bestandteil einer Rollstation mit einer Schwenkeinrichtung für den Wickelkern ist, aufweist, daß die Rolle mit der Schwenkeinrichtung von dem Auflager des Doppeltragwalzenrollers übernommen und unter Freigabe beider Tragwalzen über die zweite Tragwalze auf die Abstützwalze der Rollstation verlagert und dort bis zum Erreichen des vorgesehenen Enddurchmessers der Rolle fertiggewickelt wird. Durch dieses Verfahren werden die Vorteile des Doppeltragwalzenrollers und des Pope-Rollers, dem die Rollstation entspricht miteinander
verknüpft, ohne zugleich die jeweils auftretenden Nachteile in Kauf nehmen zu müssen. So beginnt der Aufwickelvorgang auf den Tragwalzen des Doppeltragwalzenrollers und unter Einsatz der Belastungswalze, so daß von Anfang an die Wicklung eines harten Kerns ermöglicht, der Voraussetzung dafür ist, daß beim Weiterwickeln keine Teleskopierung auftritt. Außerdem sollen von Anfang an konstante Bahnspannungsverhältnisse geschaffen werden. Dabei bietet die Belastungswalze auch noch die Möglichkeit, die Anpressung individuell ein- oder beidseitig - je nach den Erfordernissen - einzustellen. Die Flächenpressung ergibt sich aus den beiden Anlagebereichen an beiden Tragwalzen. Erst wenn die Rolle ein entsprechendes Gewicht aufweist, wird die Anpressung über die Belastungswalze aufgehoben und die Rolle dann auf den Pope-Roller bzw. in die Rollstation übernommen und bis zum vorgesehenen Enddurchmesser dort fertiggewickelt.
Zu diesem Zeitpunkt ist aber das
Gewicht der Rolle bereits so groß, daß die Abstützkraft auf der Abstützwalze der Rollstation ausreicht, um mit konstanten Bahnspannungsverhältnissen und hartem Kern passergenau und ohne Registerfehler arbeiten zu können. Gleichzeitig wird damit der besondere Vorteil erreicht, daß der Doppeltragwalzenroller in dem Seitenteil des Aufwickelvorgangs gleichsam wieder frei wird, und zwar für einen längeren Zeitraum, so daß es problemlos möglich ist, einen neuen Wickelkern vorzubereiten, zu positionieren und ihn dann beim fliegenden Rollenwechsel wickelbereit zur Verfügung zu haben.
According to the invention, this is achieved in the method of the type described in the introduction in that the material to be wound is first wound onto a winding core resting on the two support rollers of the double support roller roller until the roller has sufficient weight for the pressure on a support roller which the stationary mounted, driven Is part of a rolling station with a swivel device for the winding core, that the role with the swivel device is taken over by the support of the double carrier roller and with the release of both carrier rollers via the second carrier roller onto the support roller of Rollstation relocated and there is finished winding until the intended final diameter of the roll. Through this process, the advantages of the double carrier roller roller and the Pope roller to which the roller station corresponds are combined
linked without having to accept the disadvantages that arise in each case. Thus, the winding process begins on the support rollers of the double support roller roller and using the loading roller, so that from the beginning it is possible to wind a hard core, provided that no telescoping occurs during further winding. In addition, constant web tension conditions should be created from the start. The load roller also offers the option of individually adjusting the pressure on one or both sides - depending on the requirements. The surface pressure results from the two contact areas on both carrier rollers. Only when the roll has a corresponding weight is the pressure released via the loading roller and the roll is then transferred to the Pope-Roller or into the roll station and finished there up to the intended final diameter.
At this point, however, that is
The weight of the roll is already so great that the support force on the support roller of the roll station is sufficient to be able to work with constant web tension conditions and a hard core in register and without register errors. At the same time, the special advantage is achieved that the double carrier roller in the side part of the winding process is free again, for a longer period of time, so that it is easily possible to prepare a new winding core, position it and then ready to wrap it during the flying reel change To have available.

Nach der Ãœbernahme der Rolle durch die
Rollstation kann bereits ein neuer Wickelkern wickelbereit gemacht und beim Erreichen des vorgesehenen Enddurchmessers der vorangehend gewickelten Rolle in das Auflager der Tragwalzen des Doppeltragwalzenrollers bei Weiterlauf der Wickelbahn abgesenkt werden, wobei gleichzeitig die Bahn des Wickelguts zwischen der zweiten Tragwalze und der Abstützwalze durchtrennt wird. Es ergeben sich dabei eindeutige geometrische Verhältnisse und es steht ausreichend Zeit zur Verfügung, um den Rollenwechsel problemlos durchzuführen.
After taking on the role by
A new winding core can already be made ready for winding on the roll station and when the intended final diameter is reached the previously wound roll are lowered into the support of the support rollers of the double support roller roller as the winding path continues, the web of the winding material being cut between the second support roller and the support roller at the same time. This results in clear geometrical relationships and there is sufficient time to carry out the roll change without any problems.

Mit der Schwenkeinrichtung der Rollstation kann zugleich die fertiggewickelte Rolle abgeführt, danach ein Wickelkern aufgenommen und in einer Zwischenstation an dem Doppeltragwalzenroller abgelegt werden und darauf die auf den Tragwalzen gewickelte Rolle übernommen und auf die Abstützwalze der Rollstation geschwenkt werden. Der Schwenkvorgang der Schwenkeinrichtung der Rollstation wird also in jeder Bewegungsphase genutzte und für die vielfältigen angegebenen Funktionen eingesetzt. Eine gesonderte Transportvorrichtung und deren Steuerung wird damit entbehrlich.With the swiveling device of the roll station, the finished wound roll can be removed at the same time, then a winding core can be picked up and placed in an intermediate station on the double support roller reel and the roll wound on the support rollers can then be taken over and pivoted onto the support roller of the roll station. The swiveling process of the swiveling device of the rolling station is therefore used in every movement phase and used for the various functions specified. A separate transport device and its control is therefore unnecessary.

Die Bahn des Wickelguts kann in der Bewegung von oben nach unten durchtrennt werden, so daß die Bewegungsrichtungen des Absenkens eines neuen Wickelkerns in das Auflager an den beiden Tragwalzen und die Bewegungsrichtung der messerartigen Schneideinrichtung übereinstimmen. Dabei ist eine sehr genaue zeitliche Abstimmung zwischen beiden Bewegungen ohne Weiteres möglich und es ergibt sich der Vorteil, daß die Tragwalzen des Doppeltragwalzenrollers relativ nahe beieinander angeordnet werden können, woraus wiederum der Vorteil resultiert, daß auch Wickelkerne mit relativ kleinem Durchmesser eingesetzt werden können, und dies auch bei großen Arbeitsbreiten. Schließlich kann auch die Abstützwalze der Rollstation sehr nahe an die zweite Tragwalze des Doppeltragwalzenroller herangerückt werden, wodurch die gesamte Vorrichtung eine kurze Bauweise erhält und zudem der Übernahmevorgang der Rolle zwischen dem Doppeltragwalzenroller und der Rollstation nur eine kurze Zeit in Anspruch nimmt und dabei nur kleine Wege überbrückt werden müssen.The path of the winding material can be cut in the movement from top to bottom, so that the directions of movement of the lowering of a new winding core into the support on the two support rollers and the direction of movement of the knife-like cutting device match. A very precise timing between the two movements is easily possible and there is the advantage that the support rollers of the double support roller roller can be arranged relatively close together, which in turn results in the advantage that winding cores with a relatively small diameter can be used, and even with large working widths. Finally, the support roller of the roller station can also be moved very close to the second support roller of the double support roller roller, which gives the entire device a short construction and also the takeover process of the roller between the double carrier roller roller and the roller station only takes a short time and only small paths need to be bridged.

Der Doppeltragwalzenroller der eingangs beschriebenen Art kennzeichnet sich erfindungsgemäß dadurch, daß hinter den beiden Tragwalzen eine Rollstation mit einer eigenen, ortsfest gelagerten und angetriebenen Abstützwalze sowie einer zugehörigen Schwenkeinrichtung vorgesehen ist, daß die Abstützwalze einen größeren Durchmesser als die Tragwalzen aufweist, und daß die Schwenkeinrichtung um die Achse der Abstützwalze schwenkbar angeordnet ist. Damit wird eine Kombination eines Doppeltragwalzenrollers mit einem Pope-Roller, der der Rollstation entspricht, geschaffen, wobei die Tragwalzen des Doppeltragwalzenrollers und die Abstützwalze der Rollstation unmittelbar aufeinanderfolgend nahe beieinander angeordnet werden können. Die Tragwalzen des Doppeltragwalzenrollers können vorteilhaft einen vergleichswieise kleinen Durchmesser aufweisen, während andererseits unabhängig davon der Durchmesser der Abstützwalze vorteilhaft groß, jedenfalls größer als der Durchmesser der Tragwalzen, gewählt werden kann. Trotzdem lassen sich die Tragwalzen und die Abstützwalzen unmittelbar benachbart zueinander anordnen. Durch diese Gestaltung wird auch erreicht, daß die Größe der Kontaktflächen und die Flächenpressung in den Kontaktbereichen weitgehend günstig gestaltet wird, so daß Bahnspannungsstöße nicht auftreten. Damit wird die Vorrichtung insbesondere zur Anwendung in Druckmaschinen geeignet, die passergenau arbeiten müssen. Für kleine Rollendurchmesser werden die Vorteile - gute Anfangswickelhärte und konstante Bahnspannung - des Doppeltragwalzenrollers voll in Anspruch genommen, während bei großen Rollendurchmessern die Gewichtskomponente der Rolle für den weiteren Aufwickelvorgang auf dem Pope-Roller ausreicht. Damit erhält die Rolle ein kantengenaues Aussehen und die Bahnspannung wird in allen Aufwickelphasen im wesentlichen konstant gehalten.The double idler roller of the type described above is characterized according to the invention in that behind the two idler rollers a roll station with its own stationary and driven support roller and an associated swiveling device is provided, that the idler roller has a larger diameter than the idler rollers, and that the swivel device around the axis of the support roller is pivotally arranged. This creates a combination of a double carrier roller roller with a Pope roller, which corresponds to the rolling station, the carrier rollers of the double carrier roller roller and the support roller of the roller station being able to be arranged in immediate succession close to one another. The support rollers of the double support roller roller can advantageously have a comparatively small diameter, while on the other hand, regardless of this, the diameter of the support roller can advantageously be chosen to be large, in any case larger than the diameter of the support rollers. Nevertheless, the support rollers and the support rollers can be arranged directly adjacent to one another. This design also ensures that the size of the contact areas and the surface pressure in the contact areas are largely inexpensive, so that web tension surges do not occur. The device is therefore particularly suitable for use in printing presses which have to work in register. For small reel diameters, the advantages - good initial winding hardness and constant web tension - of the double carrier roller reel are fully utilized, while with large reel diameters the weight component of the reel is sufficient for the further winding process on the Pope-Reel. This gives the roll an edge-accurate appearance and the web tension is kept essentially constant in all winding phases.

Die Schwenkeinrichtung kann zwei Schwenkarme aufweisen, auf denen Aufnahmeteile für den Wickelkern verschieblich angeordnet sind; die Schwenkarme mit den Aufnahmeteilen sind einerseits in den Bereich über den Tragwalzen und andererseits über die Wickelstellung der Rollstation hinaus bis zu einer Ablegestation für die fertiggewickelten Rollen schwenkbar, so daß die Schwenkeinrichtung vielfältige Funktionen erfüllen kann, zu deren Realisierung bisher jeweils gesonderte Vorrichtungsteile erforderlich waren.The swivel device can have two swivel arms, on which receiving parts for the winding core are arranged displaceably; the swivel arms with the receiving parts can be swiveled on the one hand into the area above the support rollers and on the other hand beyond the winding position of the rolling station up to a depositing station for the fully wound rolls, so that the swiveling device can perform a variety of functions which previously required separate device parts for their realization.

Der Wickelkern kann im Bereich über den Tragwalzen und/oder im Bereich der Rollstation in axial gesicherten Lagern geführt sein. Auch dies trägt zu einem kantengenauen Aufwickeln bei.The winding core can be guided in axially secured bearings in the area above the support rollers and / or in the area of the rolling station. This also contributes to a precise winding.

Die Schwenkvorrichtung der Rollstation kann zugleich als Zuführeinrichtung für die Wickelkerne und als Abführeinrichtung für die Rollen ausgebildet sein. Es versteht sich, daß die Schwenkvorrichtung damit zusätzliche Schwenkwinkel überstreichen muß und eine entsprechende Vorrichtung für die Steuerung dieser Bewegung erforderlich ist. Da aber die Aufnahmeteile an den Schwenkarmen ohnehin in radialer Richtung betätigbar sein müssen, ist der zusätzliche Aufwand gering.The swiveling device of the rolling station can also be designed as a feed device for the winding cores and as a removal device for the rolls. It goes without saying that the swivel device must therefore sweep over additional swivel angles and a corresponding device is required to control this movement. However, since the receiving parts on the swivel arms must be operable in the radial direction anyway, the additional effort is low.

Es kann eine Zwischenstation zum Ablegen wickelbereiter Wickelkerne durch die Schwenkvorrichtung vorgesehen sein, aus der die Wickelkerne in das durch die beiden Tragwalzen gebildete Auflager gelangen. Natürlich ist es auch möglich, wickelbereite Wickelkörper auf andere Weise in Position zu bringen. Die vorgeschlagene Ausführungsform ermöglicht es jedoch, den Rollenwechsel vollständig zu automatisieren.An intermediate station for depositing winding cores ready for winding can be provided by the swiveling device, from which the winding cores get into the support formed by the two support rollers. Of course, it is also possible to position winding-ready winding bodies in another way. However, the proposed embodiment enables the roll change to be fully automated.

Im Bereich über den beiden Tragwalzen können sich vertikal erstreckende Führungselemente für Aufnahmeklauen am Wickelkern und für die Belastungswalze tragende Lager vorgesehen sein, wobei mit den Lagern der Belastungswalze die Schneideinrichtung zum Durchtrennen des Wickelguts zwischen der zweiten Tragwalze und der Abstützwalze verbunden ist. Damit ist ohne Weiteres die Bewegung der Belastungswalze und der Schneideinrichtung synchronisiert, so daß die Abstimmung dieser beiden Vorgänge aufeinander keinerlei Schwierigkeiten bereitet.In the area above the two support rollers, vertically extending guide elements for receiving claws on the winding core and for bearings bearing the load roller can be provided, with the bearings Loading roller is connected to the cutting device for severing the winding material between the second support roller and the support roller. So that the movement of the loading roller and the cutting device is easily synchronized, so that the coordination of these two processes does not pose any difficulties.

Die Erfindung wird anhand eines bevorzugten Ausführungsbeispiels weiter beschrieben und erläutert. Es zeigen:

Der Doppeltragwalzenroller weist einen üblichen Maschinenrahmen 1 mit zwei säulenartigen Wänden 2 rechts und links auf, die brückenartig miteinander verbunden bzw. aneinander abgestützt sind. Der Übersichtlichkeit halber ist nur eine Wand 2 dargestellt. Zwischen den beiden Wänden 2 sind zwei Tragwalzen 3 und 4 ortsfest gelagert, die im Sinne der eingezeichneten Pfeile angetrieben werden. Die beiden Wände 2 sind mit sich vertikal erstreckenden Führungselementen 5 versehen, die einmal zur Vertikalführung von Aufnahmeklauen 6 für einen Wickelkern 7 und zum anderen zur Führung einer Belastungswalze 8 dienen. Der Wickelkern 7 weist im einzelnen eine Wickelstange 9 und eine Hülse 10 auf. Die Hülse wird in üblicher Weise an der Wickelstange 9 lösbar befestigt. Die zeichnerische Darstellung dieser Einzelheiten ist sehr vereinfacht, um die Übersichtlichkeit zu wahren. Es versteht sich, daß die Wickelstange 9 nicht direkt in den Aufnahmeklauen 6 gelagert ist, sondern daß hier zusätzliche Lagerelemente vorgesehen sind. Bahnförmiges Wickelgut 11 wird in Richtung eines Pfeils 12 kontinuierlich herangeführt, d. h. ohne Unterbrechung und mit konstanter Geschwindigkeit. Dieses Wickelgut 11 muß auf dem Wickelkern 7 bzw. der Hülse 10 zu einer Rolle 13 aufgewickelt werden. Zu diesem Zweck liegt die Rolle 13 auf einem durch die beiden Tragwalzen 3 und 4 gebildeten Auflager 14 auf, stützt sich also in zwei Punkten ab und wird durch die Tragwalzen 3 und 4 angetrieben. Die Antriebsgeschwindigkeit der Tragwalze 4 kann etwas größer als die Geschwindigkeit der Tragwalze 3 sein, um auch hier Spannung auf das Wickelgut 11 auszuüben. Während des Aufwickelns in dieser Stellung liegt von Anfang an die Belastungswalze 8, die gemäß Pfeil 15 in den Führungselementen 5 vertikal verfahrbar ist, oben auf der Rolle 13 auf; aus Übersichtlichkeitsgründen ist hier die Belastungswalze 8 in ihrer oberen Endstellung, also abgehoben von dem Umfang der Rolle 13, dargestellt. Mit der Lagerung der Belastungswalze 8 sind Ausleger 16 verbunden, die eine messerartige Schneideinrichtung 17 tragen, die sich quer über die Breite der Bahn des Wickelguts 11 erstreckt. Der Maschinenrahmen 1 trägt auch eine Zwischenstation 18 sowie eine Gleitbahn 19. Die Zwischenstation 18 ist zur Aufnahme eines neuen Wickelkerns beim Rollenwechsel bestimmt und so hoch angeordnet, daß eine teilweise bewickelte Rolle 13 unter ihr hindurchtransportiert werden kann. Die Gleitbahn 19 endet relativ zu den Aufnahmeklauen 6 an den Führungselementen 5. In Zuordnung zu den Führungselementen 5 sind verschiebbare Rastebolzen 33 vorgesehen, die zur Aufnahme bzw. Freigabe der Einheit aus Wickelkern 7 und Belastungswalze 8 dienen und über Hydraulikzylinder 34 angetrieben werden. Damit ist ein Doppeltragwalzenroller mit seinen wesentlichen Elementen vorgesehen.The double carrier roller roller has a conventional machine frame 1 with two column-like walls 2 on the right and left, which are connected to one another in a bridge-like manner or are supported on one another. For the sake of clarity, only one wall 2 is shown. Between the two walls 2, two support rollers 3 and 4 are mounted in a fixed position, which are driven in the direction of the arrows shown. The two walls 2 are provided with vertically extending guide elements 5, which are used for the vertical guidance of receiving claws 6 for a winding core 7 and for the guidance of a loading roller 8. The winding core 7 has a winding rod 9 and a sleeve 10 in detail. The sleeve is in the usual way on the winding rod 9 releasably attached. The graphic representation of these details is very simplified in order to maintain clarity. It goes without saying that the winding rod 9 is not mounted directly in the receiving claws 6, but that additional bearing elements are provided here. Web-like winding material 11 is continuously fed in the direction of an arrow 12, ie without interruption and at a constant speed. This winding material 11 must be wound up on the winding core 7 or the sleeve 10 to form a roll 13. For this purpose, the roller 13 rests on a support 14 formed by the two support rollers 3 and 4, is therefore supported in two points and is driven by the support rollers 3 and 4. The drive speed of the support roller 4 can be somewhat greater than the speed of the support roller 3 in order to exert tension on the winding material 11 here as well. During the winding in this position, the loading roller 8, which can be moved vertically in the guide elements 5 according to arrow 15, rests on the top of the roller 13 from the start; For reasons of clarity, the loading roller 8 is shown here in its upper end position, that is to say raised from the circumference of the roller 13. Booms 16 are connected to the bearing of the loading roller 8 and carry a knife-like cutting device 17 which extends across the width of the web of the winding material 11. The machine frame 1 also carries an intermediate station 18 and a slideway 19. The intermediate station 18 is intended to receive a new winding core when changing the reel and is arranged so high that a partially wound reel 13 can be transported under it. The slideway 19 ends relative to the receiving claws 6 on the guide elements 5. In association with the guide elements 5, displaceable locking bolts 33 are provided, which serve to receive or release the unit comprising the winding core 7 and the loading roller 8 and are driven by hydraulic cylinders 34. A double carrier roller roller with its essential elements is thus provided.

Dem Doppeltragwalzenroller ist eine einem bekannten Pope-Roller entsprechende Rollstation 20 nachgeschaltet, der eine Abstützwalze 21 aufweist, die ebenso wie die Tragwalzen 3 und 4 ortsfest, aber angetrieben am Maschinenrahmen 1 gelagert ist. Die Abstützwalze 21 weist einen wesentlich größeren Durchmesser auf als die Tragwalzen 3 und 4. Die Walzen 3, 4, 21 sind so angeordnet, daß sie sich tangential an eine gemeinsame horizontale Ebene von unten anlagern. Andererseits sind die Lager dieser drei Walzen so nahe aneinandergerückt, daß lediglich die für die Drehbewegung der Walzen erforderlichen Spalte zwischen den Walzen gebildet werden. Dies ermöglicht es, auch vergleichsweise kleine Hülsendurchmesser einzusetzen. Die Abstützwalze 21 wird gemäß Pfeil 22 angetrieben. Die Rollstation 20 weist darüberhinaus als wesentliches Element eine Schwenkeinrichtung 23 auf, die um eine Achse 24 schwenkbar ist, welche zugleich die Drehachse der Abstützwalze 21 bildet. Im einzelnen sind im Rahmen der Schwenkeinrichtung 23 zwei Schwenkarme 25 vorgesehen, die rechts und links am Maschinenrahmen 1 gelagert sind. Auf jedem Schwenkarm 25 ist ein Aufnahmeteil 26 verschiebbar in Richtung eines Doppelpfeils 27 geführt. Für die Relativbewegung der Aufnahmeteile 26 gegenüber den Schwenkarmen 25 sind je eine Kolbenzylindereinheit 28 auf jedem Schwenkarm 25 gelagert. Auch die beiden Aufnahmeteile 26 sind ähnlich wie die Aufnahmeklauen 6 zur Aufnahme eines Wickelkerns 7 bzw. der Wickelstange 9 ausgebildet, wobei auch hier aus Übersichtlichkeitsgründen zwischengeschaltete Lager, Klemmeinrichtungen u. dgl. weggelassen sind. Die Aufnahmeteile 26 sind vermittels der Schwenkarme 25 um die Achse 24 schwenkbar, und zwar nach beiden Richtungen, wie durch einen Doppelpfeil 29 angedeutet.The double carrier roller roller is followed by a roller station 20 corresponding to a known Pope roller, which has a support roller 21 which, like the carrier rollers 3 and 4, is mounted on the machine frame 1 in a stationary but driven manner. The support roller 21 has a much larger diameter than the support rollers 3 and 4. The rollers 3, 4, 21 are arranged so that they are tangent to a common horizontal plane from below. On the other hand, the bearings of these three rollers are so close together that only the gaps required for the rotary movement of the rollers are formed between the rollers. This makes it possible to use comparatively small sleeve diameters. The support roller 21 is driven according to arrow 22. The rolling station 20 also has, as an essential element, a pivoting device 23 which can be pivoted about an axis 24, which at the same time forms the axis of rotation of the support roller 21. In detail, two swivel arms 25 are provided in the frame of the swivel device 23, which are mounted on the right and left of the machine frame 1. On each swivel arm 25, a receiving part 26 is slidably guided in the direction of a double arrow 27. For the relative movement of the receiving parts 26 with respect to the swivel arms 25, a piston-cylinder unit 28 is mounted on each swivel arm 25. The two receiving parts 26 are similar to the receiving claws 6 for receiving a winding core 7 or the winding rod 9, with intermediate bearings, clamping devices and. Like. are omitted. The receiving parts 26 can be pivoted about the axis 24 by means of the swivel arms 25, specifically in both directions, as indicated by a double arrow 29.

Es ist eine Aufnahme- und Transporteinrichtung 30 für eine Aufnahme- und Transporteinrichtung 30 für fertig gewickelte Rollen 13 vorgesehen, die Aufnahmeelemente 31 aufweist, die gemäß Doppelpfeil 32 höhenveränderlich angeordnet sind. Die Aufnahme- und Transporteinrichtung 30 kann als verfahrbarer Schlitten o. dgl. ausgebildet sein. Sie dient zur Aufnahme der fertig gewickelten Rolle und zum Abtransport.A pick-up and transport device 30 for a pick-up and transport device 30 for finished wound rolls 13 is provided, which has pick-up elements 31, which are arranged according to the double arrow 32 to change the height. The receiving and transport device 30 can be designed as a movable carriage or the like. It is used to take up the finished wound roll and to transport it away.

Der Ablauf des Aufwickelverfahrens wird anhand der Figuren 2 bis 7 verdeutlicht, die stark schematisiert sind, so daß die wesentlichen Schritte besser erkennbar werden. Das bahnförmige Wickelgut 11 wird gemäß Figur 2 kontinuierlich zugeführt und gelangt über nicht näher bezeichnete Umlenkwalzen zu den Tragwalzen 3 und 4 und wird hier auf der Hülse 10 des Wickelkerns 7 zu der Rolle 13 aufgewickelt. Der Durchmesser der Rolle 13 möge beispielsweise bis zum halben vorgesehenen Enddurchmesser angewachsen sein.
Während dieses Aufwickelvorgangs drückt die Belastungswalze 8 die Rolle 13 gegen die beiden Tragwalzen 3 und 4 an, was insbesondere zum Wickelbeginn erforderlich ist. Ein neuer Wickelkern 7, bestehend aus Wickelstange 9 und Hülse 10, ist einlegebereit vorbereitet, d. h. auf einer Mantellinie der Hülse 10 mit einem Klebestreifen versehen und so in die Aufnahmeteile 26 der Schwenkeinrichtung 23 eingesetzt. Die Schwenkeinrichtung 23 der Rollstation 20 fungiert hier als Transporteinrichtung für den Wickelkern 7.
The course of the winding process is illustrated with the aid of FIGS. 2 to 7, which are highly schematic, so that the essential steps can be better recognized. The web-like winding material 11 is fed continuously according to FIG. 2 and reaches the support rollers 3 and 4 via deflection rollers (not specified in more detail) and is wound here on the sleeve 10 of the winding core 7 to form the roll 13. The diameter of the roller 13 may have increased, for example, up to half the final diameter.
During this winding process, the loading roller 8 presses the roller 13 against the two support rollers 3 and 4, which is particularly necessary at the start of the winding. A new winding core 7, consisting of winding rod 9 and sleeve 10, is prepared ready for insertion, ie is provided with an adhesive strip on a surface line of the sleeve 10 and is thus inserted into the receiving parts 26 of the swivel device 23. The swivel device 23 of the rolling station 20 functions here as a transport device for the winding core 7.

Wie Figur 3 erkennen läßt, wurde die Schwenkvorrichtung 23 im Uhrzeigersinn verschwenkt und die Aufnahmeteile 26 ausgefahren, so daß der neue Wickelkern 7 in der Zwischenstation 18 abgelegt wird. Anschließend werden die Aufnahmeteile 26 radial an den Schwenkarmen 25 einfahren und unter die Wickelstange 9 der Rolle 13 gebracht (Fig. 4), wobei sie die Wickelstange 9 bzw. die Rolle 13 übernehmen und unter Fortsetzung des Aufwickelvorgangs über die Tragwalze 4 hinweg befördern, bis die Rolle 13 auf der Abstützwalze 21 aufsetzt. Es versteht sich, daß vor der Übernahme der Rolle 13 die Belastungswalze 8 angehoben worden ist. Diese kann beispielsweise in ihrer obere Endlage, wie dies in Figur 1 dargestellt ist, verfahren worden sein. Die Schwenkbewegung der Schwenkarme 25 Gegen den Uhrzeigersinn wird fortgesetzt, wobei die Rolle 13 unter der Zwischenstation 18 hindurchtritt` und zwar solange, bis die Rolle schräg oberhalb der Abstützwalze 21 zu liegen kommt, wie dies Figur 5 zeigt. Während dieser Transportbewegung wird der Aufwickelvorgang ebenfalls fortgesetzt, weil ja auch das Wickelgut 11 weiterhin zugeführt wird. Sobald die Rolle 13 gleichsam von der Rollstation 20 gemäß Figur 5 übernommen-worden ist, erfolgt der Transport des neuen Wickelkerns 7 aus der Zwischenstation 18 über die Gleitbahn 19 abwärts bis in die Aufnahmeklauen 6 hinein. Zu diesem Zweck muß der Wickelkern 7,an sich nur ausgelöst werden, so daß er an der Gleitbahn 19 herabrutscht. Anschließend wird die Belastungswalze 8 in Kontakt mit der Hülse 10 des neuen, noch unbewickelten Wickelkerns 7 gebracht. Die aus Wickelkern 7 und Belastungswalze 8 gebildete Einheit wird dann auf den durch Hydraulikzylinder 34 rückziehbaren Rastebolzen 33 abgelegt, ohne daß sie zunächst Kontakt mit dem Wickelgut 11 hat (Figur 5). In dieser Stellung wird ausschließlich mit der Rollstation aufgewickelt und der Enddurchmesser der Rolle 13 erreicht. Die Aufteilung des Aufwickelns in den Doppeltragwalzenroller einerseits und die einem bekannten Pope-Roller entsprechende Rollstation 20 andererseits kann je nach den gegebenen Verhältnissen erfolgen. So ist es beispielsweise möglich, etwa 50 bis 70 % des Durchmessers der Rolle 13 auf dem Doppeltragwalzenroller zu wickeln und nur den Rest auf der Rollstation.As can be seen in FIG. 3, the swiveling device 23 was swiveled clockwise and the receiving parts 26 extended so that the new winding core 7 is deposited in the intermediate station 18. The receiving parts 26 are then moved in radially on the swivel arms 25 and brought under the winding rod 9 of the roller 13 (FIG. 4), taking over the winding rod 9 or the roller 13 and conveying them over the carrying roller 4 while continuing the winding operation until the roller 13 is placed on the support roller 21. It is understood that the load roller 8 has been raised before taking over the roller 13. This can, for example, in its upper end position this is shown in FIG. 1. The swiveling movement of the swivel arms 25 continues counterclockwise, the roller 13 passing under the intermediate station 18 until the roller comes to lie obliquely above the support roller 21, as shown in FIG. 5. During this transport movement, the winding process is also continued, because the winding material 11 is still being fed. As soon as the roll 13 has been taken over, so to speak, by the rolling station 20 according to FIG. 5, the new winding core 7 is transported from the intermediate station 18 downward via the slide track 19 into the receiving claws 6. For this purpose, the winding core 7 only has to be triggered per se, so that it slides down on the slideway 19. Then the loading roller 8 is brought into contact with the sleeve 10 of the new, yet unwound winding core 7. The unit formed from the winding core 7 and the loading roller 8 is then placed on the locking bolt 33 which can be retracted by the hydraulic cylinder 34 without first having contact with the winding material 11 (FIG. 5). In this position, only the roller station is wound up and the final diameter of the roller 13 is reached. The division of the winding into the double carrier roller roller on the one hand and the rolling station 20 corresponding to a known Pope roller on the other hand can take place depending on the given conditions. For example, it is possible to wind about 50 to 70% of the diameter of the roller 13 on the double carrier roller roller and only the rest on the roller station.

Ist dann der vorgesehene Enddurchmesser der Rolle 13 erreicht, so wird gemäß Figur 6 die Einheit aus dem neuen Wickelkern 7 und der Belastungswalze 8 mit der Schneideinrichtung 17 durch Betätigung der Hydraulikzylinder 34 und damit Rückzug der Rastebolzen 33 ausgeklinkt, so daß diese herabfallen kann. Auch ein Anpressen mittels Zylindern ist an dieser Stelle möglich.If the intended end diameter of the roller 13 is then reached, the unit consisting of the new winding core 7 and the loading roller 8 with the cutting device 17 is released by actuating the hydraulic cylinders 34 and thus retracting the locking bolts 33, so that the latter can fall down. Pressing using cylinders is also possible at this point.

Wichtig ist nur, daß die Schneideinrichtung 17 das bahnförmige Wickelgut zwischen der Tragwalze 4 und der Abstützwalze 21 durchtrennt, und daß der an der Hülse 10 befindliche Klebestreifen den auf diese Art und Weise gebildeten Anfang des bahnförmigen Wickelguts 11 aufnimmt und um den neuen Wickelkern 7 bzw. die Hülse 10 aufwickelt, so daß für eine neue Rolle 13 das Auflager 14 des Doppeltragwalzenrollers entsprechend benutzt wird. Eine nicht dargestellte, von rechts an die Tragwalze 3 angestellte und den neuen Bahnaufgang einklemmende, angetriebene Gummiwalze kann dafür sorgen, daß die Bahnspannung auch unmittelbar nach dem Durchtrennen der Bahn erhalten bleibt.It is only important that the cutting device 17 cuts the web-shaped winding material between the support roller 4 and the support roller 21, and that the adhesive strip located on the sleeve 10 takes up the beginning of the web-shaped winding material 11 formed in this way and around the new winding core 7 or the sleeve 10 winds up so that the support 14 of the double carrier roller is used accordingly for a new roll 13. A driven rubber roller, not shown, set from the right to the support roller 3 and clamping the new web entrance, can ensure that the web tension is maintained immediately after the web has been severed.

Gemäß Figur 7 vergrößert sich dann wiederum der Durchmesser der Rolle 13 auf den beiden Tragwalzen 3 und 4, während die vorher gewickelte Rolle 13 nunmehr von den Aufnahmeteilen 26 an den Schwenkarmen 25 durch Verschwenkung der Schwenkarme 25 entgegen dem Uhrzeigersinn in die Aufnahme- und Transporteinrichtung 30 bzw. deren Aufnahmeelemente 31 abgegeben wird. Es versteht sich, daß zu diesem Zweck die Aufnahmeteile 26 etwas ausgefahren werden, so daß die Rolle 13 ihren Kontakt zu der Abstützwalze 21 verliert, wie dies Figur 7 zeigt. Daran anschließend wird wiederum ein neuer Wickelkern 7 eingelegt, wie dies in Figur 2 dargestellt ist.According to FIG. 7, the diameter of the roller 13 on the two support rollers 3 and 4 then increases again, while the previously wound roller 13 is now moved from the receiving parts 26 to the swivel arms 25 by pivoting the swivel arms 25 counterclockwise into the receiving and transport device 30 or the receiving elements 31 is delivered. It goes without saying that for this purpose the receiving parts 26 are extended somewhat so that the roller 13 loses its contact with the support roller 21, as shown in FIG. Then a new winding core 7 is inserted again, as shown in FIG. 2.

Die in den Figuren 8 und 9 dargestellte Ausführungsform des Doppeltragwalzenrollers ist an sich ähnlich aufgebaut wie die in den Figuren 1 bis 7 dargestellte Ausführungsform, jedoch mit dem Unterschied, daß die Zwischenstation 18 nicht mehr ortsfest vorgesehen ist, sondern auf dem Träger, auf welchem auch die Schneideinrichtung 17 ist. Es ist damit eine Baueinheit aus Belastungswalze 8, Schneideinrichtung 17 und Zwischenstation 18 gebildet, die gemeinsam höhenverfahrbar vorgesehen ist. Zu diesem Zweck sind an dem Träger, auf dem auch die Belastungswalze 8 gelagert ist, zwei Hebelarme 35 schwenkbar um die Achse der Belastungswalze 8 vorgesehen, die an ihren freien Enden Lagerausnehmungen 36 tragen. Ein Antrieb 37, beispielsweise in Form eines Elektromotors mit einer Zahnradgetriebestufe dient zum Verschwenken der Hebelarme 35, wobei die beiden Endstellungen in den Figuren 8 und 9 dargestellt sind.The embodiment of the double carrier roller scooter shown in FIGS. 8 and 9 has a structure similar to that of the embodiment shown in FIGS. 1 to 7, but with the difference that the intermediate station 18 is no longer provided in a fixed position, but on the carrier, on which one the cutter 17 is. A unit is thus formed from the loading roller 8, the cutting device 17 and the intermediate station 18, which is provided to be movable in height together. For this purpose, on the carrier on which also the loading roller 8 is mounted, two lever arms 35 are provided pivotably about the axis of the loading roller 8, which carry bearing recesses 36 at their free ends. A drive 37, for example in the form of an electric motor with a gear transmission stage, serves to pivot the lever arms 35, the two end positions being shown in FIGS. 8 and 9.

Nachdem eine fertiggewickelte Wickelrolle 13 mit Hilfe der Schwenkeinrichtung 23 von der Rollstation 20 abgenommen und in die Aufnahmeelemente 31 der Aufnahme- und Transporteinrichtung 30 überführt und damit weggeschafft worden ist, wird ein neuer Wickelkern, 7 aus Wickelstange 9 und Hülse 10 in den Aufnahmeteil 26 der Schwenkarme 25 eingelegt. Die Schwenkarme 25 werden in die in Figur 8 dargestellte Lage verschwenkt, so daß sich der Wickelkern 7 exakt oberhalb der Lagerausnehmungen 36 der Hebelarme 35 befindet. Wächst im Verlauf des Aufwickelns der Wickelrolle 13 in der Vorwickeleinheit des Doppeltragwalzenrollers der Durchmesser an, so wird über die Belastungswalze 8 auch deren Träger und damit auch die Hebelarme 35 der Zwischenstation 18 angehoben, wodurch der Wickelkern 7 zwangsweise von den Lagerausnehmungen 36 übernommen wird. Es versteht sich, daß sowohl der Aufnahmeteil 26 wie auch die Lagerausnehmungen 36 durch hydraulische Festklemmeinrichtungen gesichert sind, so daß der Wickelkern 7 jeweils fixiert gehalten wird. Der Übersichtlichkeit halber sind diese Elemente nicht dargestellt. Nachdem der Wickelkern 7 in den Lagerausnehmungen 36 ruht und gehalten ist, ist die Schwenkeinrichtung 23 wieder frei und kann die Wickelrolle 13 aus dem Doppeltragwalzenroller übernehmen, ähnlich wie dies bei der anderen Ausführungsform in Figur 4 dargestellt ist. Es versteht sich, daß vor und während der Übernahme die Baueinheit mit der Belastungswalze 8 und der Zwischenstation 18 noch ein Stück weiter hoch gefahren wird, damit die Belastungswalze 8 von der Wickelrolle 13 freikommt. Die Wickelrolle 13 wird dann in die in Figur 9 dargestellte Zwischenlage verschwenkt, so daß in dieser Fertigwickeleinheit die Rollstation 20 ihre Funktion als Pope-Roller ausüben kann. Es folgt das Absenken der Baueinheit etwa in die in Figur 9 dargestellte Lage, wobei gleichzeitig oder nacheinander der Antrieb 37 in Tätigkeit gesetzt wird, so daß die Hebelarme 35 verschwenken und den Wickelkern 7 auf den Rastebolzen 33 auflagern. Es versteht sich, daß dabei die Wickelstange 9, die vorher in den Lagerausnehmungen 36 hydraulisch festgespannt war, freigegeben wird. Die Hebelarme 35 werden dann noch etwas weiter in Uhrzeigersinn verschwenkt, wie dies Figur 9 zeigt, damit die Baueinheit aus Belastungswalze 8 und Hebelarmen 35 wieder nach oben gefahren werden kann, wobei die Hebelarme 35 wieder zurückverschwenkt werden, und zwar in eine Lage, wie dies Figur 8 zeigt, so daß letztendlich die Schneideinrichtung 17 den untersten Punkt dieser Baueinheit bildet. Die Baueinheit wird dann wieder abgesenkt, bis die Belastungswalze 8 auf der Hülse 10 aufsetzt. Beim Rollenwechsel und zum Durchtrennen des Wickelguts 11 wird dann der Hydraulikzylinder 34 ausgelöst, wodurch die Schneideinrichtung 17 bei Erreichen des vorgesehenen maximalen Durchmessers der Wickelrolle 13 auf der Rollstation 20 das Wickelgut 11 durchtrennt und der neue Wickelkern 7 auf dem Doppeltragwalzenroller beginnt eine neue Bahn aufzuwickeln. Die übrige Wirkungsweise ist analog zu der Wirkungsweise des Ausführungsbeispiels der Figuren 1 bis 7. Es sei nur noch darauf hingewiesen, daß die Übernahme des neuen Wickelkerns aus dem Aufnahmeteil 26 in die Lagerausnehmungen 36 nicht nur in Abhängigkeit von dem wachsenden Durchmesser der Wickelrolle auf dem Doppeltragwalzenroller durchgeführt werden kann, sondern auch gesteuert zu einem solchen Zeitpunkt, wenn die Wickelrolle 13 auf dem Doppeltragwalzenroller bereits eine solche Größe und ein solches Gewicht erreicht hat, daß die Auflage der Belastungswalze 8 nicht mehr erforderlich ist. Die Baueinheit aus Belastungswalze 8, Zwischenstation 18 und Schneideinrichtung erfüllt eine Mehrfachfunktion. Sie dient über die Belastungswalze 8 der Aufbringung des Anpreßdrucks und damit der Bereitstellung konstanter Bahnspannungsverhältnisse in der Vorwickeleinheit. Sie trägt die Schneideinrichtung 17 und stellt auch die erforderliche Bewegung für diese Schneideinrichtung zur Verfügung. Sie nimmt schließlich die Zwischenstation 18 auf und sie bildet ein Teil einer Transporteinrichtung des Wickelkerns aus der Zwischenstation 18 bis zur Übergabe an die Rastebolzen 33.After a completely wound winding roll 13 has been removed from the rolling station 20 with the aid of the swiveling device 23 and transferred to the receiving elements 31 of the receiving and transport device 30 and thus removed, a new winding core 7 from the winding rod 9 and sleeve 10 is inserted into the receiving part 26 of the Swivel arms 25 inserted. The pivot arms 25 are pivoted into the position shown in Figure 8, so that the winding core 7 is located exactly above the bearing recesses 36 of the lever arms 35. If the diameter increases in the course of the winding of the winding roller 13 in the pre-winding unit of the double carrier roller roller, then its carrier and thus also the lever arms 35 of the intermediate station 18 are also raised via the loading roller 8, whereby the winding core 7 is forcibly taken over by the bearing recesses 36. It is understood that both the receiving part 26 and the bearing recesses 36 are secured by hydraulic clamping devices, so that the winding core 7 is held in a fixed manner. For the sake of clarity, these elements are not shown. After the winding core 7 rests and is held in the bearing recesses 36, the swiveling device 23 is free again and can take over the winding roll 13 from the double carrier roll roll, similar to that shown in the other embodiment in FIG. It is understood that before and during the takeover, the assembly with the loading roller 8 and the intermediate station 18 is raised a little further so that the loading roller 8 is released from the winding roll 13. The winding roll 13 is then shown in FIG Intermediate position pivoted so that the roll station 20 can perform its function as Pope-Roller in this finished winding unit. There follows the lowering of the assembly approximately into the position shown in FIG. 9, the drive 37 being activated simultaneously or in succession, so that the lever arms 35 pivot and support the winding core 7 on the locking bolt 33. It is understood that the winding rod 9, which was previously hydraulically clamped in the bearing recesses 36, is released. The lever arms 35 are then pivoted a little further clockwise, as shown in FIG. 9, so that the assembly comprising the loading roller 8 and lever arms 35 can be moved up again, the lever arms 35 being pivoted back again, in a position such as this FIG. 8 shows that the cutting device 17 ultimately forms the lowest point of this structural unit. The assembly is then lowered again until the loading roller 8 touches the sleeve 10. When changing the reel and severing the winding material 11, the hydraulic cylinder 34 is then triggered, as a result of which the cutting device 17 cuts the winding material 11 on the rolling station 20 when the intended maximum diameter of the winding roller 13 is reached, and the new winding core 7 on the double support roller reel begins to wind up a new web. The remaining mode of operation is analogous to the mode of operation of the exemplary embodiment in FIGS. 1 to 7. It should only be pointed out that the takeover of the new winding core from the receiving part 26 into the bearing recesses 36 is not only dependent on the growing diameter of the winding roll on the double carrier roller can be carried out, but also controlled at such a time when the winding roller 13 on the double carrier roller roller has already reached such a size and weight that the support of the loading roller 8 is no longer required. The unit consisting of loading roller 8, intermediate station 18 and cutting device fulfills a multiple function. she serves Via the loading roller 8, the application of the contact pressure and thus the provision of constant web tension conditions in the pre-winding unit. It carries the cutting device 17 and also provides the required movement for this cutting device. It finally receives the intermediate station 18 and forms part of a transport device for the winding core from the intermediate station 18 until it is transferred to the locking bolts 33.
