Abstract

The invention describes a winding apparatus (1) for winding up a web-like material (2), comprising a winding core (5) on which the web-like material (2) can be wound up to form a material roll, also comprising a web-guiding roller (3) which guides the web-like material (2) before it reaches the winding core or the material roll, or as it reaches the same, and further comprising a pressure-exerting element (6) which presses the web-like material onto the winding core or the roll once it is already resting on the winding core or the roll, it being possible for the pressure-exerting roller to be moved relative to the winding core. The pressure-exerting element (6) is mounted, at both ends, in lever arms (12) which form a pair of levers. These lever arms are mounted in a rotatable manner, and the pressure-exerting roller can therefore be pivoted about the bearing points (13) of the lever arms.

Description

Die Erfindung betrifft eine Wickelvorrichtung zum Aufwickeln eines bahnförmigen Materials nach dem Oberbegriff des Anspruchs 1.The invention relates to a winding device for winding a web-shaped material according to the preamble of claim 1.

Bahnförmiges Material, beispielsweise Kunststofffolie, welche in einer Bahnherstellungsvorrichtung, beispielsweise in einer Extrusionsvorrichtung, hergestellt wird, wird häufig nicht direkt, also "inline" weiterverarbeitet, sondern zunächst in einer genannten Wickelvorrichtung zu Wickeln aufgewickelt. Erst diese Wickel werden einer weiterverarbeitenden Maschine zugeführt. Zu solchen weiterverarbeitenden Maschinen gehören Druckmaschinen, Schlauchherstellmaschinen und viele andere Maschinen.
Auch andere Materialien, wie etwa Papier, werden in einer Wickelvorrichtung aufgewickelt und in Form von Wickeln einer weiter verarbeitenden Maschine zugeführt.Web-shaped material, for example plastic film, which is produced in a web production device, for example in an extrusion device, is often not processed directly, that is to say "inline", but initially wound into a winding device. Only these rolls are fed to a further processing machine. Such finishing machines include printing machines, hose making machines and many other machines.
Other materials, such as paper, are wound in a winding device and fed in the form of coils of a further processing machine.

Häufig werden diese Wickel dadurch gebildet, dass das bahnförmige Material auf einem Wickelkern aufgewickelt wird. Bevor das bahnförmige Material diesen Wickelkern beziehungsweise den Wickel, auf dem bereits bahnförmiges Material aufgewickelt ist, erreicht, wird es über eine Bahnführungswalze geführt. Diese Bahnführungswalze kann in einem geringen Abstand zu dem Wickelkern bzw. zu dem Wickel angeordnet sein (so genannter "Spaltwickler") oder das bahnförmige Material direkt an den Wickelkern oder den Wickel andrücken. In letzterem Fall wird die Wickelvorrichtung als Kontaktwickler bezeichnet. In beiden Fällen ist die genannte Bahnführungswalze in der Regel die letzte Walze, über die das bahnförmige Material geführt wird, bevor es oder während es den Wickelkern oder den Wickel erreicht.Often, these windings are formed by winding the web-like material onto a winding core. Before the web-shaped material reaches this winding core or the winding on which already web-shaped material is wound, it is guided over a web guide roll. This web guide roller can be arranged at a small distance from the winding core or to the winding (so-called "gap winder") or press the web-like material directly to the winding core or the winding. In the latter case, the winding device is referred to as a contact winder. In both cases, said web guide roll is typically the last roll over which the web-shaped material passes before it or while it reaches the winding core or the roll.

Um einen Lufteinschluss zwischen dem Wickelkern beziehungsweise dem Wickel und der neuen Lage des bahnförmigen Materials zu vermeiden, ist dem Wickel häufig ein Andrückelement zugeordnet, welches an den Wickel anstellbar ist Dieses Andrückelement ist in der Regel als Andrückwalze ausgestaltet.In order to avoid air entrapment between the winding core or the winding and the new layer of the web-like material, the winding is often associated with a pressing element, which can be adjusted to the winding This pressure element is designed as a pressure roller in the rule.

In bekannten Wickelvorrichtungen umfasst die Mechanik, welche dem Anstellen der Andrückelemente an den Wickel dient, Schlitten, in denen die Andrückwalze oder das Andrückelement beidendig gelagert ist, wobei die Schlitten auf zueinander parallel verlaufenden Schienen verschiebbar angeordnet sind. Diese Schlenen sind an Wandungen befestigt, welche auch die Wickelkerne tragen. Die die Andrückwalzen lagernden Schlitten werden mittels geeigneter Stellmittel, wie etwa einer Kolbenzylindereinheit, in Richtung auf den Wickelkern bewegt oder entfernt.In known winding devices, the mechanism which is used to adjust the pressing elements to the winding comprises slides in which the pressure roller or the pressure element is mounted at both ends, the slides being displaceably arranged on mutually parallel rails. These Schlenen are attached to walls, which also carry the winding cores. The carriages supporting the pressure rollers are moved or removed by means of suitable adjusting means, such as a piston-cylinder unit, in the direction of the winding core.

Nachteilig bei dieser Art, die Andrückwalze an den Wickelkern anzustellen, ist der große Platzbedarf, den eine lineare Führung der Schlitten mit sich bringt.A disadvantage of this type, hiring the pressure roller to the winding core, the large footprint, which brings a linear guidance of the carriage with it.

Daher schlägt die US 4 431 140 vor, dass das Andrückelement beidendig in ein Hebelarmpaar bildende Hebelarmen gelagert ist, welche drehbar gelagert sind, so dass die Andrückwalze um die Lagerpunkte der Hebelarme schwenkbar ist. Aus dieser Schrift ist weiterhin bekannt, dass zumindest ein weiterer Wickelkern und zumindest eine weitere in Hebelarmen drehbar gelagerte Andrückwalze vorgesehen sind.Therefore, the beats US 4 431 140 in that the pressure element is mounted at both ends in a lever arm pair forming lever arms, which are rotatably mounted, so that the pressure roller is pivotable about the bearing points of the lever arms. From this document is also known that at least one further winding core and at least one further rotatably mounted in lever arms pressure roller are provided.

Die Aufgabe der vorliegenden Erfindung ist es, eine Wickelvorrichtung vorzuschlagen, bei der die mechanik, welche dem Anstehen des Andrückelements an den Wickel dient, weniger Platz benötigt.The object of the present invention is to propose a winding device, in which the mechanics, which serves the queuing of the pressing element to the winding, requires less space.

Die Aufgabe wird gelöst durch eine Wickelvorrichtung nach dem Oberbegriff des Anspruchs 1, die sich zudem durch die Merkmale des Kennzeichens des Anspruchs 1 auszeichnet.The object is achieved by a winding device according to the preamble of claim 1, which is also characterized by the features of the characterizing part of claim 1.

Demnach ist der Schwenkbereich der Hebelarme so bemessen, dass eine Andrückwalze alternativ mit zwei Wickelkemen in Kontakt treten kann. Auf diese Weise kann die Andrückwalze, die über keinen eigenen Rotationsantrieb verfügt, durch einen sich drehenden Wickelkern in Rotation versetzt werden. Somit kann die Andrückwalze beschleunigt werden, bevor sie den Wickel berührt. Eine Beschleunigung der Andrückwalze durch den Wickel, auf welchem bereits bahnförmiges Material aufgewickelt wurde, kann zu Schäden an dem bahnförmigen Material führen.Accordingly, the pivoting range of the lever arms is dimensioned so that a pressure roller can alternatively come into contact with two winding cores. In this way, the pressure roller, which does not have its own rotary drive, can be set in rotation by a rotating winding core. Thus, the pressure roller can be accelerated before it touches the winding. An acceleration of the pressure roller through the winding, on which already web-shaped material has been wound, can lead to damage to the web-like material.

Das Andrückelement kann eine Andrückwalze sein, welche in diesem Hebelarmpaar drehbar gelagert ist. Die Hebelarme sind in den Wandungen, in welchen auch der Wickelkern gelagert ist, drehbar gelagert. Da die Lagerpunkte des Andrückelements in den Hebelarmen und die Lagerpunkte der Hebelarme in den Wandungen nicht zusammenfallen, ist das Andrückelement letztendlich um die Lagerpunkte der Hebelarme schwenkbar. Auf diese Weise werden für die Bewegung des Andrückelements keine Schienen mehr benötigt, sondern nur noch Hebelarme, welche in einem Punkt drehbar gelagert sind. Aus diesem Grunde kann die erfindungsgemäße Wickelvorrichtung wesentlich kompakter gebaut werden als eine Wickelvorrichtung nach dem bekannten Stand der Technik.The pressure element may be a pressure roller, which is rotatably mounted in this Hebelarmpaar. The lever arms are rotatably mounted in the walls in which the winding core is mounted. Since the bearing points of the pressure element in the lever arms and the bearing points of the lever arms in the walls do not coincide, the pressure element is ultimately pivotable about the bearing points of the lever arms. In this way, no rails are needed for the movement of the pressing element, but only lever arms which are rotatably mounted in one point. For this reason, the winding device according to the invention can be constructed much more compact than a winding device according to the known prior art.

Von entscheidender Bedeutung ist die Frage des Platzbedarfes in so genannten Wendewicklern. Bei dieser Art von Wickelvorrichtungen sind der Wickelkern und die Mechanik zum Anstellen des Andrückelements an Scheiben oder Platten befestigt, welche drehbar im Maschinengestell gelagert sind. An diesen Scheiben oder Platten sind jeweils zumindest ein zweiter Wickelkern und wenigstens eine weitere Mechanik zum Anstellen von Andrückelementen gelagert beziehungsweise befestigt. Ein Wendewickler dient, nachdem ein Wickel fertig gewickelt wurde, dem zügigen Anwickeln des durch einen Schnitt gebildeten neuen Bahnanfangs auf dem zweiten Wickelkern. Die erfindungsgemäße Wickelvorrichtung umfasst daher die genannten Merkmale eines Wendewicklers. Gerade In diesem Fall beeinflusst der Platzbedarf der Mechanik zum Anstellen des Andrückelements direkt die Größe der Scheiben beziehungsweise der Platten und auch die Antriebsleistung, die zu deren Drehung im Maschinengestell notwendig Ist.Of crucial importance is the question of space requirements in so-called turret winder. In this type of winding devices, the winding core and the mechanism for adjusting the pressing element are attached to disks or plates which are rotatably mounted in the machine frame. At least one second winding core and at least one further mechanism for adjusting pressure elements are respectively mounted or fastened to these disks or plates. A turret winder serves after a Winding was finished, the rapid Anwickeln formed by a cut new web start on the second core. The winding device according to the invention therefore comprises the mentioned features of a turret winder. In this case, the space requirement of the mechanism for adjusting the pressing element directly affects the size of the discs or the plates and also the drive power, which is necessary for their rotation in the machine frame.

Vorteilhafterweise sind den Wickelkemen Antriebsmittel zugeordnet, welche diese mit einem Drehmoment beaufschlagen. Dabei kann jedem Wickelkern ein eigener Antrieb zugeordnet sein. Alternativ können zwei oder mehrere Wickelkerne von einem Antrieb angetrieben sein, wobei eine lösbare Kupplung zwischen dem Antriebsstrang und dem Wickelkern vorgesehen ist, um den Wickel zum Zweck des Abtransports anhalten zu können, während ein weiterer Wickelkern weiter bewickelt wird.Advantageously, the winding core drive means are assigned, which act on these with a torque. Each winding core can be assigned its own drive. Alternatively, two or more Winding cores are driven by a drive, wherein a releasable coupling between the drive train and the winding core is provided in order to be able to stop the winding for the purpose of Abtransports while another winding core is further wound.

Gegenstand der Erfindung ist zudem ein Verfahren zum kontinuierlichen Aufwickeln eines bahnförmigen Materials zu Wickeln nach dem Anspruch 9. Weitere Verfahrensschritte, die zu dem erfindungsgemäßen Verfahren gehören, werden weiter unten im Rahmen der gegenständlichen Beschreibung beschrieben.The invention also relates to a method for continuously winding a web-shaped material to wind according to claim 9. Further method steps, which belong to the method according to the invention are described below in the context of the present description.

The contact roller 3 is attached to the winding 4, which is wound on a winding core 5, employed, so that the run of the contact roller 3 web-like material is placed on the winding. In the transport direction of the material behind the contact roller a pressure roller is employed on the winding 4, which presses the uppermost layer of the sheet-like material 2 with pressure to the winding 4 to prevent air pockets. Due to the strength of the pressure, the so-called winding hardness can be determined.

Der Wickelkern 5 ist beidendig in Scheiben drehbar gelagert, von denen nur die hintere Scheibe 7 dargestellt ist. Die Scheiben sind ihrerseits drehbar im nicht gezeigten Maschinengestellt gelagert. Die Kontaktwalze 3 ist über Elemente, die eine Bewegung der Kontaktwalze 3 relativ zum Wickelkern 5 ermöglichen, ebenfalls am Maschinengestell gelagert.The winding core 5 is rotatably mounted at both ends in disks, of which only the rear disk 7 is shown. The discs are in turn rotatably mounted in the machine position not shown. The contact roller 3 is also mounted on the machine frame via elements that allow movement of the contact roller 3 relative to the winding core 5.

Die Andrückwalze 6 ist über nicht dargestellte Verschiebeschlitten in Führungen 8 gelagert, wobei die Führungen an den Scheiben befestigt sind. Mit Hilfe von Kolben-Zylinder-Einheiten oder anderen geeigneten Antrieben kann die Andrückwalze 6 relativ zu den Führungen und damit relativ zum Wickelkern 5 verschoben werden.The pressure roller 6 is mounted on slides not shown in guides 8, wherein the guides are attached to the discs. With the help of piston-cylinder units or other suitable drives the pressure roller 6 can be moved relative to the guides and thus relative to the winding core 5.

In den erwähnten Scheiben sind jeweils noch ein zweiter Wickelkern 9 und weitere Führungen 10 gelagert beziehungsweise befestigt. Die Führungen 10 tragen ebenfalls über in diesen verschiebbare Schlitten eine zweite Andrückwalze 11, die dem Wickelkern 9 zugeordnet ist.In each case, a second winding core 9 and further guides 10 are mounted or fastened in the disks mentioned. The guides 10 also carry in this slidable carriage a second pressure roller 11 which is associated with the winding core 9.

Durch eine Drehung der Scheiben 7 kann der Wickelkern 9 in Richtung auf die Kontaktwalze geschwenkt werden, so dass dieser Wickelkern 9 in Kontakt mit dem bahnförmigen Material gelangt. Durch die Drehung der Scheiben wird der Wickel 4 von der Kontaktwalze 3 abgeschwenkt. Nun kann das bahnförmige Material von einer nicht dargestellten Schneidvorrichtung durchtrennt werden, so dass ein neuer Bahnanfang entsteht, der durch geeignete Mittel auf dem Wickelkern 9 festgelegt werden kann. Der alte Wickel 4 kann nun aus der Wickelvorrichtung entfernt und durch einen leeren Wickelkern ersetzt werden. Auf diese Weise entsteht, ohne dass die Wickelvorrichtung zwecks Wechsels des Wickelkerns angehalten werden müsste, ein neuer Wickel.By rotating the disks 7, the winding core 9 can be pivoted in the direction of the contact roller, so that this winding core 9 comes into contact with the web-shaped material. By the rotation of the discs, the winding 4 is pivoted away from the contact roller 3. Now, the sheet-like material can be cut by a cutting device, not shown, so that a new web beginning arises, which can be determined by suitable means on the winding core 9. The old winding 4 can now be removed from the winding device and replaced by an empty winding core. In this way, without the winding device would have to be stopped in order to change the winding core, a new winding.

Die Fig. 2 zeigt eine erfindungsgemäße Wickelvorrichtung 1 während des Wickelbetriebes. Die im Vergleich mit der in der Fig. 1 dargestellten Wickelvorrichtung gleichen Elemente sind in der Fig. 2 mit den gleichen Bezugszeichen versehen. Im Unterschied zu der Wickelvorrichtung nach dem Stand der Technik ist bei der erfindungsgemäßen Vorrichtung die Andrückwalze 6 in einem Hebelarmpaar gelagert, von denen nur der hintere Hebelarm 12 dargestellt ist. Beide Hebelarme des Hebelarmpaares sind über geeignete Kopplungselemente, wie etwa Verbindungsstangen, miteinander verbunden, so dass die Drehachse der Andrückwalze stets parallel zur Drehachse des Wickelkerns verläuft.The Fig. 2 shows a winding device 1 according to the invention during the winding operation. The compared with in the Fig. 1 shown winding device are the same elements in the Fig. 2 provided with the same reference numerals. In contrast to the winding device according to the prior art, the pressure roller 6 is mounted in a pair of lever arm, of which only the rear lever arm 12 is shown in the apparatus according to the invention. Both lever arms of the Hebelarmpaares are connected to each other via suitable coupling elements, such as connecting rods, so that the axis of rotation of the pressure roller is always parallel to the axis of rotation of the winding core.

In einer vorteilhaften Ausführungsform sind dazu an jeder Scheibe 7 je ein Zahnkranz oder Zahnkranzsegment befestigt, auf dem sich an einer Kopplungswelle befestigte Zahnräder abwälzen. Zwischen Zahnkranz bzw. - segment und Zahnrädern der Kopplungswelle können weitere Zahnräder vorgesehen sein. Die Kopplungswelle kann durch eine axiale Bohrung der Andrückwalze 6, 11 geführt sein. Wird nun einer der beiden Hebelarme mit einem Drehmoment beaufschlagt, so dreht sich die Kopplungswelle, und überträgt ein Drehmoment auf den jeweils anderen Hebelarm, wobei sich das Ende der Kopplungswelle, welches in dem anderen Hebelarm drehbar gelagert ist, ebenfalls auf einem Zahnkranz bzw. -segment abwälzt. Auf diese Weise wird eine exakt gleiche Winkelstellung der Hebelarme gewährleistet. Dieser Sachverhalt wird nachstehend noch anhand der Figur 9 erläutert.In an advantageous embodiment, a sprocket or sprocket segment are attached to each disc 7, on which roll off gears mounted on a coupling shaft. Between sprocket or - segment and gears of the coupling shaft further gears can be provided. The coupling shaft can be guided through an axial bore of the pressure roller 6, 11. If now one of the two lever arms is acted upon by a torque, the coupling shaft rotates, and transmits a torque to the respective other lever arm, wherein the end of the coupling shaft, which is rotatably mounted in the other lever arm, also on a ring gear or segment rolls. In this way, an exact same angular position of the lever arms is guaranteed. This situation will be described below on the basis of FIG. 9 explained.

Der Hebelarm 12 ist über ein Lager 13 in der Scheibe 7 gelagert. Die Rotationsachse der Andrückwalze 6 liegt parallel zu der Drehachse des Lagers 13. Beide Achsen fluchten aber nicht. Gleiches gilt auch für alle anderen Hebelarme, die in dieser und den folgenden Figuren dargestellt sind, aber auch für die Hebelarme, die nicht dargestellt sind.The lever arm 12 is mounted on a bearing 13 in the disc 7. The axis of rotation of the pressure roller 6 is parallel to the axis of rotation of the bearing 13. Both axes are not aligned. The same applies to everyone else Lever arms, which are shown in this and the following figures, but also for the lever arms, which are not shown.

Das Schwenken der Hebelarme erfolgt beispielsweise durch einen Antriebsmotor, auf dessen Rotorachse ein Ritzel aufgesteckt und befestigt ist. Dieses Ritzel kämmt mit einem Zahnrad oder einem Zahnradsegment, das an einem Hebelarm des Hebelarmpaares befestigt ist und dessen Rotationsachse mit der Drehachse des Lagers 13 fluchtet. Als Antriebsmotor wird ein Luftmotor bevorzugt, der sehr kompakt und leicht ist. Hierauf wird nachstehend im Rahmen der Beschreibung der Fig. 9 noch weiter eingegangen.The pivoting of the lever arms, for example, by a drive motor, on the rotor axis, a pinion is attached and attached. This pinion meshes with a gear or a gear segment, which is fixed to a lever arm of the Hebelarmpaares and whose axis of rotation is aligned with the axis of rotation of the bearing 13. As the drive motor, an air motor is preferred, which is very compact and lightweight. This will be described below in the description of the Fig. 9 further elaborated.

Die Andrückwalze 11, welche analog zur im Hebelarm 12 gelagerten Andrückwalze 6 im Hebelarm 14 gelagert und angetrieben ist, ist in der in Fig. 2 dargestellten Betriebssituation in einer von dem Wickelkern 9 abgeschwenkten Position dargestellt.The pressure roller 11, which is mounted and driven analogously to the pressure roller 12 mounted in the lever arm 6 in the lever arm 14, is in the in Fig. 2 shown operating situation in a pivoted-away from the winding core 9 position.

Die Fig. 3 zeigt die bereits in der Fig. 2 gezeigte, erfindungsgemäße Wickelvorrichtung 1, nachdem die Scheiben so weit gedreht wurden, dass der Wickelkern 9 die ursprüngliche Position des Wickelkerns 5 einnimmt. Das bahnförmige Material 2 wird in der gezeigten Situation zunächst weiter auf dem Wickel aufgewickelt, wobei das bahnförmige Material 2 auch über die Andrückwalze 11 läuft.The Fig. 3 shows the already in the Fig. 2 shown winding device 1 according to the invention, after the discs were rotated so far that the winding core 9 assumes the original position of the winding core 5. The web-shaped material 2 is wound in the situation shown initially further on the winding, wherein the web-shaped material 2 also passes over the pressure roller 11.

Nachdem die dargestellte Betriebssituation erreicht wurde, erfolgt durch eine nicht dargestellte Trenneinrichtung ein Durchtrennen des bahnförmigen Materials. Das dadurch entstandene Bahnende wird weiter auf den Wickel 4 aufgewickelt. Der durch die Trennung des bahnförmigen Materials entstandene Bahnanfang wird durch eine geeignete Maßnahme, etwa Festlegen durch ein Klebemittel, auf den Wickelkern 9 festgelegt. Das bahnförmige Material 2 wird nun auf dem Wickelkern 9 aufgewickelt. Zwischenzeitlich hat das entstandene Bahnende den alten Wickel 4 erreicht, so dass die Andrückwalze 11 nicht mehr in Kontakt mit dem bahnförmigen Material 2 steht. Sobald der neue Bahnanfang auf dem Wickelkern festgelegt wurde, wird der Hebelarm 14 in Richtung auf diesen Wickelkern verschwenkt und damit die Andrückwalze 11 an den Wickelkern angestellt. Nach dem Ersetzen des Wickels 4 durch einen neuen Wickelkern ist der Wechselvorgang abgeschlossen und die in der Fig. 2 gezeigte Betriebssituation wieder hergestellt.After the illustrated operating situation has been reached, a severing of the web-shaped material is carried out by a separating device, not shown. The resulting tail is further wound on the winding 4. The web beginning caused by the separation of the sheet-like material is fixed to the winding core 9 by a suitable measure, such as fixing by means of an adhesive. The web-shaped material 2 is now wound on the winding core 9. In the meantime, the resulting tail has reached the old winding 4, so that the pressure roller 11 is no longer in contact with the web-shaped material 2. Once the new web start has been set on the winding core, the lever arm 14 is pivoted in the direction of this winding core and thus the pressure roller 11 to the Employed hub. After replacing the roll 4 by a new hub of the change process is completed and in the Fig. 2 restored operating situation shown.

Es ist zu betonen, dass die in den Figuren 2 und 3 dargestellte Wickelvorrichtung insbesondere bei langsam laufendem bahnförmigem Material Verwendung findet. Der Grund dafür ist darin zu suchen, dass die Andrückwalze 11, die sich in ihrer in der Fig. 2 dargestellten Position in Ruhe befindet oder sogar vom vorherigen Wickeln auf den Wickelkern 9 entgegen der Bahnlaufrichtung rotiert, von dem bahnförmigen Material in Rotation bzw. in entgegen gesetzte Rotation versetzt werden muss, sobald sie dieses berührt. Eine hohe Transportgeschwindigkeit des Materials 2 würde jedoch eine hohe Beschleunigung der Andrückwalze notwendig machen und damit eine große Kraft benötigen. Die dabei wirkenden Kräfte könnten jedoch zu einer Beschädigung des bahnförmigen Materials führen. Die Grenze, bei der die beschriebene Vorrichtung noch eingesetzt werden kann, ohne das bahnförmige Material zu beschädigen, liegt bei einer Transportgeschwindigkeit von 150 - 200 Metern pro Minute, wobei diese Grenze auch von den Materialeigenschaften abhängig sein kann.It should be emphasized that in the Figures 2 and 3 shown winding device is used in particular in slow-running sheet-like material use. The reason for this is to be found in that the pressure roller 11, which in their in the Fig. 2 shown position at rest or even rotated from the previous winding on the winding core 9 against the web running direction, must be offset from the web-like material in rotation or in opposite rotation as soon as they touched this. However, a high transport speed of the material 2 would make a high acceleration of the pressure roller necessary and thus require a large force. However, the forces acting thereby could lead to damage of the web-like material. The limit at which the described device can still be used without damaging the web-like material lies at a transport speed of 150-200 meters per minute, although this limit may also depend on the material properties.

Eine Wickelvorrichtung, die auch zum Aufwickeln von schnell laufendem Material geeignet ist, wird in den Figuren 4 bis 8 gezeigt.A winding device, which is also suitable for winding fast running material, is in the FIGS. 4 to 8 shown.

Die Figur 4 zeigt schematisch eine weitere Ausführungsform der erfindungsgemäßen Wickelvorrichtung 1. Diese Wickelvorrichtung stimmt im Wesentlichen mit der in der Fig. 2 dargestellten Wickelvorrichtung überein, jedoch umfasst die in der Fig. 4 dargestellte Vorrichtung zusätzliche Umlenkrollen 15 und 16. Diese Umlenkrollen 15 und 16 sind drehbar in Haltern gelagert, welche an den Scheiben befestigt sind. Die Zahl der Umlenkrollen ist nicht auf zwei beschränkt, es können mehrere Umlenkrollen vorgesehen sein. In der Figur 4 sind nur die an der hinteren Scheibe befestigten Halter 17 dargestellt. Die Funktion der Umlenkrollen 15, 16 wird anhand der folgenden Beschreibung der Figuren 5 bis 8 deutlich, in denen der Wickelkernwechselvorgang illustriert wird.The FIG. 4 schematically shows a further embodiment of the winding device according to the invention 1. This winding device is substantially the same as in the Fig. 2 The winding device shown, however, includes in the Fig. 4 shown device additional pulleys 15 and 16. These pulleys 15 and 16 are rotatably mounted in holders which are fixed to the discs. The number of pulleys is not limited to two, it may be provided a plurality of pulleys. In the FIG. 4 only the holders 17 attached to the rear disc are shown. The function of the guide rollers 15, 16 will be described with reference to the following description of FIGS. 5 to 8 clearly, in which the hub change operation is illustrated.

Die Figur 5 zeigt die Wickelvorrichtung 1, bei der nun der Hebelarm 14 in Richtung auf den Wickelkern 9 verschwenkt worden ist, so dass die Andrückwalze 11 in einem reibschlüssigen Kontakt mit dem Wickelkern 9 steht. Der Wickelkern 9 wird nun durch einen Antrieb in Rotation versetzt, womit auch die Andrückwalze 11 in Rotation versetzt wird. Die Rotationsgeschwindigkeit ist dabei so gewählt, dass die Umfangsgeschwindigkeit der Andrückwalze 11 im Wesentlichen der Transportgeschwindigkeit des bahnförmigen Materials entspricht.The FIG. 5 shows the winding device 1, in which now the lever arm 14 has been pivoted in the direction of the winding core 9, so that the pressure roller 11 is in frictional contact with the winding core 9. The winding core 9 is now rotated by a drive in rotation, whereby the pressure roller 11 is set in rotation. The rotational speed is chosen so that the peripheral speed of the pressure roller 11 substantially corresponds to the transport speed of the web-shaped material.

In Figur 6 wird, im Vergleich zur Figur 5, zunächst die Kontaktwalze 3 relativ zur Scheibe 7 verschoben, so dass sie nicht mehr mit dem Wickel 4 in Kontakt steht. Anschließend wurden die Scheiben um einen Winkel von ungefähr 90 ° gedreht. Nach diesem Drehwinkel tritt die Umlenkrolle 15 nahezu in Kontakt mit dem bahnförmigen Material 2. Die Umlenkrolle 15 kann, abhängig vom Material, über einen externen Vorbeschleuniger verfügen. Es kann aber auch durch das bahnförmige Material in Rotation versetzt werden. Die Umlenkrolle weist einen kleinen Durchmesser auf und ist aus einem leichten Material gefertigt, so dass zu dessen Beschleunigung nur ein im Vergleich zur Beschleunigung einer Andrückwalze geringes Drehmoment aufgebracht werden muss. Die Umlenkwalzen können daher bei hohen Transportgeschwindigkeiten des bahnförmigen Materials eingesetzt werden. Während der weiteren Drehung der Scheiben wird der Hebelarm 14 verschwenkt, bis dieser in etwa parallel zum Halter 17 verläuft. Dabei erfolgt das Schwenken zeitlich so, dass die Andrückwalze 11 das bahnförmige Material 2 möglichst nicht berührt. Der Drehimpuls der nicht angetriebenen Andrückwalze 11 bleibt erhalten oder nimmt nur geringfügig ab. Das Drehen der Scheiben erfolgt weiter, bis der neue Wickelkern 9 in Kontakt mit dem bahnförmigen Material 2 getreten ist. Diese Situation ist in der Figur 7 dargestellt.In FIG. 6 will, compared to FIG. 5 , First, the contact roller 3 is displaced relative to the disc 7 so that it is no longer in contact with the winding 4. Subsequently, the discs were rotated through an angle of approximately 90 °. After this rotation angle, the guide roller 15 almost comes into contact with the web-shaped material 2. The guide roller 15 may, depending on the material, have an external Vorbeschleuniger. But it can also be rotated by the web-shaped material in rotation. The pulley has a small diameter and is made of a lightweight material, so that its acceleration only one compared to the acceleration of a pressure roller low torque must be applied. The guide rollers can therefore be used at high transport speeds of the web material. During the further rotation of the discs, the lever arm 14 is pivoted until it extends approximately parallel to the holder 17. In this case, the pivoting takes place in such a time that the pressure roller 11 does not touch the web-shaped material 2 as far as possible. The angular momentum of the non-driven pressure roller 11 is maintained or decreases only slightly. The rotation of the discs continues until the new winding core 9 has come into contact with the web-shaped material 2. This situation is in the FIG. 7 shown.

Die Figur 8 zeigt die Betriebssituation, wonach das bahnförmige Material 2 mittels einer Trennvorrichtung durchtrennt worden ist. Das entstandene Bahnende wurde auf den Wickel 4 aufgewickelt. Der neu entstandene Bahnanfang wurde wiederum auf dem neuen Wickelkern 9 festgelegt, so dass an dieser Stelle ein neuer Wickel entsteht. Der Hebelarm 14 wurde in Richtung auf den Wickelkern 9 verschwenkt und auf diese Weise die Andrückwalze an den Wickelkern 9 bzw. an den neuen Wickel in Anlage gebracht.The FIG. 8 shows the operating situation, after which the web-shaped material 2 has been severed by means of a separating device. The resulting tail was wound on the winding 4. The newly created web start was again set on the new hub 9, so that At this point a new winding is created. The lever arm 14 was pivoted in the direction of the winding core 9 and brought in this way the pressure roller to the winding core 9 and to the new roll in abutment.

Die Fig. 9 zeigt den in der Fig. 3 eingezeichneten Schnitt IX - IX. In dieser Ansicht sind nunmehr beide Scheiben 7 zu sehen, in der beide Hebelarme 14 um die als strichpunktierte Linie symbolisierte Drehachse 20 drehbar sind. An jeder Scheibe 7 ist jeweils ein Zahnkranz oder ein Zahnkranzsegment 21 befestigt. Mit jedem dieser Zahnkränzen bzw. Zahnkranzsegmenten 21 kämmt je ein Zahnrad 22, wobei beide Zahnräder mit einer Kopplungswelle 23 drehfest verbunden sind. Die Kopplungswelle 23 ist über geeignete Lager 24, etwa Kugellager, in den Hebelarmen 14 drehbar gelagert.The Fig. 9 shows the in the Fig. 3 drawn section IX - IX. In this view, now both discs 7 can be seen, in which both lever arms 14 are rotatable about the symbolized as a dotted line axis of rotation 20. On each disc 7, a sprocket or a sprocket segment 21 is attached in each case. With each of these sprockets or sprocket segments 21 meshes each have a gear 22, both gears are rotatably connected to a coupling shaft 23. The coupling shaft 23 is rotatably mounted in the lever arms 14 via suitable bearings 24, such as ball bearings.

Werden nun die Hebelarme 14 relativ zu den Scheiben 7 geschwenkt, so wird aufgrund des beschriebenen Aufbaus bewirkt, dass beide Hebelarme immer den gleichen Schwenkwinkel einnehmen.Now, if the lever arms 14 is pivoted relative to the discs 7, so causes due to the structure described that both lever arms always occupy the same tilt angle.

Die Andrückwalze 11 selbst ist auf der Kopplungswelle 23 mittels Drehlager 25 drehbar gelagert. Wie bereits beschrieben wurde, ist die Andrückwalze nicht angetrieben. Sie ist also frei drehbar gelagert.The pressure roller 11 itself is rotatably mounted on the coupling shaft 23 by means of rotary bearings 25. As already described, the pressure roller is not driven. So it is freely rotatably mounted.

Um die Hebelarme 14 relativ zu den Scheiben 7 bewegen zu können, sind an den Hebelarmen 14 Zahnräder oder Zahnrädersegmente 26 angebracht. Mit diesen Zahnrädern oder Zahnrädersegmenten 26 kämmen Ritzel 27, die auf die Antriebswellen 29 von Antriebmotoren 28 drehfest aufgebracht sind. Diese Antriebsmotoren, welche vorteilhafterweise als Luftmotoren ausgeführt sind, sind an den Scheiben 7 befestigt.
