Description

Die Erfindung betrifft eine Wickeleinrichtung zum Aufwickeln von Teilbahnen eines bahnförmigen Materials nach dem Oberbegriff des Patentanspruchs 1 und ein Verfahren zum Aufwickeln von Teilbahnen eines bahnförmigen Materials nach dem Oberbegriff des Patentanspruchs 14.The invention relates to a winding device for winding up partial webs of a web-shaped material according to the preamble of patent claim 1 and a method for winding up partial webs of a web-shaped material according to the preamble of patent claim 14.

In der Produktion insbesondere von Folien wie etwa Kunststofffolien werden Folien als Endlosmaterial produziert und in Wickeleinrichtungen auf Wickelhülsen (Papphülsen, Kunststoffhülsen, Metallhülsen,...) zu Wickeln aufgewickelt. Je nach Art der Kunststoffmaterialien neigt die Folie während des Wickelprozesses mehr oder weniger dazu, so genannte Wickeldefekte auszubilden. Ein Wickeldefekt ist z. B. der Kantenaufbau. Bei diesem Defekt klappen die äußeren Kanten des Wickels während des Wickelns um, wodurch eine deutliche Durchmesservergrößerung der Folienrolle an den Rändern des Wickels erkennbar ist. Jedoch auch ein schlechter Schnitt bzw. eine stumpfe Klinge an einer Längsschneidstation können zu einem solchen Kantenaufbau führen; durch den schlechten Schnitt entsteht eine Dickstelle an der Folienkante. Durch das stetige Aufeinanderlegen dieser Folienkante entsteht eine deutliche Durchmesservergrößerung in den Randbereichen der Folienwickel, also ein Kantenaufbau.In the production of foils in particular, such as plastic foils, foils are produced as continuous material and wound up in winding devices on winding tubes (cardboard tubes, plastic tubes, metal tubes, ...). Depending on the type of plastic materials, the film more or less tends to form so-called winding defects during the winding process. A winding defect is e.g. B. the edge structure. With this defect, the outer edges of the roll fold over during the winding, as a result of which a clear increase in the diameter of the film roll at the edges of the roll can be seen. However, even a bad cut or a blunt blade on a slitting station can lead to such an edge build-up; the bad cut creates a thick spot on the edge of the film. The continuous stacking of this film edge creates a significant increase in diameter in the edge areas of the film roll, that is, an edge build-up.

Ein Kantenaufbau führt in vielen Fällen dazu, dass die fertig produzierte Folienrolle nicht mehr abwickelbar ist. Sie reißt während des Abwickelvorgangs ständig, was beispielsweise eine automatische Verpackung von Gütern mit diesen Folienrollen unmöglich macht. Der Grund dafür ist, dass die Randbereiche der Folie wesentlich stärker beansprucht werden, so dass ein Einreißen sehr wahrscheinlich ist.In many cases, an edge build-up means that the finished film roll can no longer be unwound. It tears constantly during the unwinding process, which is the case, for example, with automatic packaging of goods makes these film rolls impossible. The reason for this is that the edge areas of the film are stressed much more, so tearing is very likely.

WO2014/076089 A1 offenbart eine Wickeleinrichtung nach dem Oberbegriff des Anspruchs 1 und ein Verfahren nach dem Oberbegriff des Anspruchs 14. WO2014 / 076089 A1 discloses a winding device according to the preamble of claim 1 and a method according to the preamble of claim 14.

Die Dokumente JP 2009 107792 A und JP H05 51154 A zeigen Vorrichtungen zum Wickeln von Folienrollen, wobei jeweils zwei Rollen vorgesehen sind, welche auf die Ränder der Folienrolle wirken. Auch die EP 0 421 232 A1 offenbart eine solche Vorrichtung.The documents JP 2009 107792 A and JP H05 51154 A show devices for winding film rolls, wherein two rolls are provided, which act on the edges of the film roll. Also the EP 0 421 232 A1 discloses such a device.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Wickelvorrichtung und ein Verfahren, bei der bzw. bei dem Teilbahnen eines bahnförmigen Materials aufgewickelt werden, vorzuschlagen, mit welchen ein solcher Kantenaufbau verringerbar oder sogar ganz vermeidbar ist.The object of the present invention is therefore to propose a winding device and a method in which or in which partial webs of a web-like material are wound, with which such an edge structure can be reduced or even avoided entirely.

Erfindungsgemäß wird diese Aufgabe durch sämtliche Merkmale des Anspruchs 1 gelöst. In den abhängigen Ansprüchen sind mögliche Ausgestaltungen der Erfindung angegeben.According to the invention, this object is achieved by all the features of claim 1. Possible embodiments of the invention are specified in the dependent claims.

Gemäß der vorliegenden Erfindung ist vorgesehen, dass wenigstens eine Rolle vorgesehen ist, deren Oberfläche an den Rändern der sich auf zwei benachbarten Wickeln (103) befindlichen Teilbahnen des bahnförmigen Materials mit einer Anstellkraft anstellbar ist. Unter "Rand" wird im Rahmen dieser Offenbarung verstanden, dass die Rolle sich nicht über die gesamte Breite des Wickels erstreckt, sondern höchstens bis zu einer Entfernung von 5 cm von der jeweiligen Stirnseite des Wickels. Jedoch ist es nicht notwendig, dass die gesamte Oberfläche der Rolle an dem Wickel anliegt. Vielmehr kann ein Teil der Oberfläche der Rolle nicht in Kontakt mit dem Wickel stehen.According to the present invention, it is provided that at least one roller is provided, the surface of which is on the edges of the partial webs of the web-shaped part located on two adjacent windings (103) Material can be adjusted with a positioning force. In the context of this disclosure, “edge” means that the roll does not extend over the entire width of the roll, but at most up to a distance of 5 cm from the respective end face of the roll. However, it is not necessary that the entire surface of the roll be against the reel. Rather, part of the surface of the roll cannot be in contact with the roll.

Mit der Erfindung ist es nun möglich, dass die Ränder des bahnförmigen Materials, welche bereits mittels der Kontaktwalze auf den Wickel gelegt wurden, angedrückt werden. Die Vermeidung des Kantenaufbaus kommt nun durch den folgenden Effekt zustande. Beim Wickeln wird in der Regel zwischen die Lagen des bahnförmigen Materials eine gewisse Menge an Luft mit eingewickelt. Auch die Luftmenge hat einen Einfluss auf den Durchmesser des gesamten Wickels, also nicht nur die Dicke des bahnförmigen Materials. Durch die Rolle an den Rändern des Wickels wird hier nun die Luft verdrängt, die nun entweder nach außen gelangt oder in Richtung der Wickelmitte gedrückt wird. Aufgrund der nun verringerten Luftmenge im Randbereich können die oben beschriebenen Wickeldefekte ausgeglichen werden, so dass der Kantenaufbau verringert wird. Eine erfindungsgemäß aufgewickelte Folie neigt beispielsweise nun nicht mehr zum Reißen, so dass eine Weiterverarbeitung zuverlässiger erfolgen kann.With the invention, it is now possible for the edges of the web-like material, which have already been placed on the winding by means of the contact roller, to be pressed on. The following effect now avoids the build-up of edges. When winding, a certain amount of air is usually wrapped between the layers of the web-like material. The amount of air also has an influence on the diameter of the entire roll, not just the thickness of the sheet material. The roll at the edges of the reel now displaces the air, which is now either released to the outside or pressed towards the center of the reel. Due to the now reduced amount of air in the edge area, the winding defects described above can be compensated for, so that the edge build-up is reduced. A film wound according to the invention tends, for example no longer to tear, so that further processing can take place more reliably.

Vorteilhaft ist es, wenn die wenigstens eine Rolle parallel zur Kontaktwalze verlagerbar ist. Damit kann die Position der Rolle an die Breite des Wickels angepasst werden, so dass die Erfindung auch bei Wickeln unterschiedlicher Breite einsetzbar ist. Ferner kann vorgesehen sein, dass eine variable Anzahl an Rollen einsetzbar ist. Damit ist es möglich, die Erfindung auch dann zu verwenden, wenn ein bahnförmiges Material vor dem Aufwickeln durch Längsschneiden zu mehreren Teilbahnen aufgeteilt wird, wobei diese Teilbahnen dann auf separate Hülsen zu unabhängigen Wickeln aufwickelbar sind. Oft befinden sich diese Hülsen jedoch auf derselben Wickelwelle. In diesem Fall ist es sogar möglich, dass eine Rolle an den Rändern von zwei zueinander benachbarten Wickeln anliegt. Damit kann einerseits die Menge an benötigten Rollen verringert werden und andererseits auch der Abstand der Wickel gering gehalten werden, ohne dass auf den Mindestabstand zweier Rollen Rücksicht genommen werden müsste. Eine einzelner Wickel wird in diesem Zusammenhang als "Nutzen" bezeichnet.It is advantageous if the at least one roller can be displaced parallel to the contact roller. The position of the roll can thus be adapted to the width of the roll, so that the invention can also be used for rolls of different widths. It can further be provided that a variable number of roles can be used. It is thus possible to use the invention even if a web-shaped material is divided into several sub-webs by longitudinal cutting before being wound up, these sub-webs then being able to be wound up on separate tubes to form independent coils. However, these sleeves are often on the same winding shaft. In this case, it is even possible for a roll to rest against the edges of two adjacent coils. On the one hand, this enables the amount of rolls required to be reduced and, on the other hand, the distance between the windings can be kept small without having to take into account the minimum distance between two rolls. In this context, a single wrap is referred to as a "benefit".

In einer vorteilhaften Weiterbildung ist vorgesehen, dass die wenigstens eine Rolle drehbar in einer Lagervorrichtung gelagert ist, welche an unterschiedlichen Stellen einer Traverse positionierbar ist, wobei insbesondere sich die Traverse parallel zur Kontaktwalze erstreckt. Damit kann die Lagervorrichtung an unterschiedlichen Orten der Traverse angeordnet und auch befestigt werden, um die oben angesprochene Anpassung an unterschiedliche Breiten des Wickels bzw. auch an die Anzahl der Nutzen zu ermöglichen. Beispielsweise kann die Lagervorrichtung auf die Traverse aufgesetzt und mit dieser verschraubt oder an diese geklemmt werden.In an advantageous development, it is provided that the at least one roller is rotatably mounted in a bearing device which can be positioned at different points on a crossmember, the crossmember in particular extending parallel to the contact roller. The bearing device can thus be arranged and also fastened at different locations on the crossmember in order to allow the above-mentioned adaptation to different widths of the roll or also to the number of uses. For example, the bearing device can be placed on the crossbar and screwed to it or clamped to it.

Bevorzugt ist jedoch, dass die Traverse als Schiene ausgebildet ist, auf welcher die Lagervorrichtung verschiebbar gelagert ist, was die Handhabung vereinfacht. Vorteilhaft ist es dabei, wenn die Lagervorrichtung als Schlitten ausgebildet ist. Eine Verschiebung erfolgt vorzugsweise händisch, eine motorische Verstellung ist allerdings ebenso denkbar.However, it is preferred that the traverse is designed as a rail on which the bearing device is slidably mounted, which simplifies handling. It is advantageous if the bearing device is designed as a slide. A shift is preferably done manually, but a motorized adjustment is also conceivable.

In einer weiteren Ausgestaltung der Erfindung, die ebenfalls vorteilhaft ist, ist die Rolle als eine langgestreckte Walze ausgebildet, welche zumindest eine in Umfangsrichtung umlaufende Erhöhung umfasst, deren Oberfläche an den Rändern der sich auf benachbarten Wickeln befindlichen Teilbahnen des bahnförmigen Materials anstellbar ist. Im Gegensatz zu den bereits beschriebenen, separaten Rollen ist hier somit eine Walze vorgesehen. Diese Walze trägt eine Erhöhung. Mit anderen Worten ist zumindest ein Ring auf der Walze angeordnet, welcher auf einen Rand des Wickels wirkt. Die Walze an sich tritt bevorzugt mit dem bahnförmigen Material nicht in Kontakt. Der Einsatz einer Walze kann im Vergleich zum Vorsehen einer Traverse eine höhere Biegesteifigkeit bringen, so dass insbesondere bei einer großen Anzahl an Nutzen die Anstellkraft über die Breite der Walze konstant ist.
Um generell eine Durchbiegung zu kompensieren, kann es im Rahmen der Erfindung vorgesehen sein, dass die Rollen oder die Erhöhungen einen unterschiedlichen Durchmesser haben, die, je näher sie relativ zur Mitte der Kontaktwalze positioniert sind, beispielsweise größer sind, da dort die größte Durchbiegung zu erwarten ist.In a further embodiment of the invention, which is also advantageous, the roller is designed as an elongate roller which comprises at least one circumferential elevation, the surface of which can be adjusted at the edges of the partial webs of the web-shaped material located on adjacent windings. In contrast to the separate roles already described, a roller is thus provided here. This roller carries an increase. In other words, at least one ring is arranged on the roller, which acts on an edge of the roll. The roller itself preferably does not come into contact with the sheet material. The use of a roller can bring a higher bending stiffness in comparison to the provision of a traverse, so that the contact force is constant over the width of the roller, in particular with a large number of uses.
In order to generally compensate for a deflection, it can be provided within the scope of the invention that the rollers or the elevations have a different diameter, which, for example, the larger the closer they are positioned relative to the center of the contact roller, since the greatest deflection increases there is expected.

In einer vorteilhaften Weiterbildung sind diese Erhöhungen entlang der Walze verschiebbar, so dass auf einfache Weise die Anpassung an die Nutzen- bzw. Wickelbreite möglich ist.
In einer weiteren Ausführungsform ist vorgesehen, dass die zumindest eine Rolle durch einen Antrieb antreibbar ist. Damit ist es nicht notwendig, dass die Rolle durch den Wickel in Rotation versetzt wird. Gerade letzteres kann insbesondere bei empfindlichen Materialien zu Beschädigungen derselben führen. Vorteilhaft ist diese Ausführungsform in Kombination mit einer bereits beschriebenen, mit Erhöhungen versehenen Walze, da hier nur ein einzelner Antrieb notwendig ist. Bei separaten Rollen werden mehrere Antriebe und/oder Getriebeverbindungen benötigt, um alle Rollen mit einer Kraft zum Drehantreiben beaufschlagen zu können. Mit einem Antrieb kann die zumindest eine Rolle in Voreilung oder in Nacheilung angetrieben werden. Das bedeutet, dass die Umfangsgeschwindigkeit größer bzw. kleiner ist als die Umfangsgeschwindigkeit des Wickels. Damit kann die Luftverdrängung bei bestimmten Materialien verbessert werden.In an advantageous further development, these elevations can be displaced along the roller, so that adaptation to the blank or winding width is possible in a simple manner.
In a further embodiment it is provided that the at least one roller can be driven by a drive. It is therefore not necessary for the roll to be set in rotation by the winding. The latter in particular can damage the same, particularly in the case of sensitive materials. This embodiment is advantageous in combination with an already described roller provided with elevations, since only a single drive is necessary here. In the case of separate rollers, several drives and / or gearbox connections are required in order to be able to apply a force for rotating the rollers. The at least one roller can be driven in advance or in lag with a drive. That means, that the peripheral speed is greater or smaller than the peripheral speed of the winding. This can improve air displacement for certain materials.

Vorteilhaft ist es, wenn die Rolle oder die Traverse an zwei Schwenkarmen angeordnet ist, welche um eine parallel zur Kontaktwalze verlaufenden Schwenkachse schwenkbar ist. Eine Anordung an Schwenkarmen ermöglicht eine einfach ausgeführte Anstellung der Rolle an einen Wickel mit einer Schwenklagerung, die etwas abseits der eigentlichen Wickelstelle angeordnet sein kann. In der Regel sind hier die Platzverhältnisse günstiger.It is advantageous if the roller or the crossbeam is arranged on two swivel arms which can be swiveled about a swivel axis running parallel to the contact roller. An arrangement on swivel arms enables the roll to be simply positioned on a reel with a swivel bearing, which can be arranged somewhat away from the actual winding point. As a rule, the space is more favorable here.

Besonders vorteilhaft ist es dabei, wenn die Drehachse der Kontaktwalze und die Schwenkachse koaxial verlaufen. Damit ist gewährleistet, dass die Rolle stets - unabhängig vom Durchmesser des Wickels - in Kontakt mit dem Wickel treten kann und dass der konstruktive Auswand gering ist.It is particularly advantageous if the axis of rotation of the contact roller and the pivot axis run coaxially. This ensures that the roll can always come into contact with the roll, regardless of the diameter of the roll, and that the design effort is low.

In weiterer, vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass eine Kraftbereitstellungseinrichtung vorgesehen ist, mit welcher die Anstellkraft bereitstellbar ist und welche sich insbesondere an einem Maschinengestell abstützt. Alternativ dazu kann sich die Kraftbereitstellungseinrichtung an den Maschinenelementen abstützen, die auch die Kontaktwalze tragen. Dies ist insbesondere dann vorteilhaft, wenn die Kontaktwalze über die genannten Maschinenelemente relativ zum Maschinengestell bewegbar ist. Durch das Vorsehen einer Kraftbereitstellungseinrichtung kann die Rolle mit einer einstellbaren Anstellkraft an den Wickel angestellt werden. Diese Anstellkraft kann insbesondere in Abhängigkeit von dem bahnförmigen Material gewählt werden.In a further, advantageous embodiment of the invention, it is provided that a force supply device is provided with which the positioning force can be provided and which is supported in particular on a machine frame. Alternatively, the power supply device can be supported on the machine elements which also carry the contact roller. This is particularly advantageous if the contact roller can be moved relative to the machine frame via the machine elements mentioned. By providing a force supply device, the roll can be set against the reel with an adjustable setting force. This contact force can be selected in particular as a function of the sheet material.

Im Zusammenhang mit dem Vorsehen von Schwenkarmen ist es vorteilhaft, wenn die Kraftbereitstellungseinrichtung auf diese Schwenkarme wirkt. Dies führt zu einer einfachen Konstruktion und Bauausführung einer erfindungsgemäßen Wickeleinrichtung.In connection with the provision of swivel arms, it is advantageous if the power supply device acts on these swivel arms. This leads to a simple construction and construction of a winding device according to the invention.

In einer erfindungsgemäßen Wickeleinrichtung kann ferner eine Anstellkraftregelung vorgesehen sein. In diesem Fall ist eine Anstellkraftmesseinrichtung vorgesehen, mit welcher die tatsächliche Anstellkraft messbar ist. In einer Rechen- und Steuervorrichtung ist dann dieser von der Anstellkraftmesseinrichtung bereitgestellte Messwert mit einem Sollwert vergleichbar. Bei Abweichungen, die einen festgelegten Grenzwert überschreiten, gibt die Rechen- und Steuereinrichtung Steuersignale an die Kraftbereitstellungseinrichtung ab, aufgrund welcher die Anstellkraft veränderbar ist. Dabei kann vorgesehen sein, dass der Sollwert für die Anstellkraft in Abhängigkeit vom Material und/oder vom Wickeldurchmesser veränderbar ist. Beispielsweise kann die Anstellkraft bei größer werdendem Wickeldurchmesser vergrößert oder verringert werden, bevorzugt in stetiger Weise. Die Änderungen können dabei über den Wickeldurchmesser linear erfolgen. Jedoch ist auch eine nichtlineare Abhängigkeit denkbar.An adjusting force control can also be provided in a winding device according to the invention. In this case, a positioning force measuring device is provided with which the actual positioning force can be measured. In a computing and control device, this measured value provided by the contact force measuring device can then be compared with a target value. In the event of deviations which exceed a defined limit value, the computing and control device emits control signals to the power supply device, on the basis of which the setting force can be changed. It can be provided that the setpoint for the contact force can be changed depending on the material and / or the winding diameter. For example, the setting force can be increased or decreased as the winding diameter increases, preferably in a steady manner. The changes can be made linearly over the winding diameter. However, a non-linear dependency is also conceivable.

Die oben genannte Aufgabe wird zusätzlich durch ein Verfahren mit den Merkmalen des Anspruchs 14 gelöst. Demnach zeichnet sich das erfindungsgemäße Verfahren dadurch aus, dass wenigstens eine Rolle mit seiner Oberfläche an den Rändern der sich auf zwei benachbarten Wickeln befindlichen Teilbahnen des bahnförmigen Materials mit einer Anstellkraft angestellt wird. Damit werden die gleichen Vorteile erzielt, wie sie bereits weiter oben im Zusammenhang mit der erfindungsgemäßen Wickelvorrichtung beschrieben wurden.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung gehen aus der nachfolgenden Beschreibung hervor, in der unter Bezugnahme auf die Figuren verschiedene Ausführungsbeispiele im Einzelnen erläutert sind. Die einzelnen Figuren zeigen nun:

The above-mentioned object is additionally achieved by a method having the features of claim 14. Accordingly, the method according to the invention is characterized in that at least one roller with its surface on the edges of the partial webs of the web-shaped material located on two adjacent windings is set with an adjusting force. The same advantages are achieved as have already been described above in connection with the winding device according to the invention.
Further advantages, features and details of the invention emerge from the following description, in which various exemplary embodiments are explained in detail with reference to the figures. The individual figures now show:

Die Figur 1 zeigt eine erfindungsgemäße Wickelvorrichtung 100, wie sie vorzugsweise mit einer Blasfolienanlage oder einer Flachfolienanlage zur Herstellung von Kunststofffolie kombiniert wird. Das bahnförmige Material 101, also vorzugsweise eine Kunststoffbahn, wird entlang einer Transportrichtung T auf eine Kontaktwalze 102, die in Richtung R1 rotiert, geführt. Im Kontaktpunkt 110 ist die Kontaktwalze an einen Wickel 103 angestellt (bzw. der Wickel 103 ist an die Kontaktwalze 102 angestellt). In diesem Kontaktpunkt 110 wird das bahnförmige Material 101 von der Kontaktwalze 102 auf den Wickel 103 geführt und dort angedrückt. Der Wickel 103 ist fest auf der Wickelwelle 104 gehalten, wobei die Wickelwelle 104 in Richtung R2 rotiert.The Figure 1 shows a winding device 100 according to the invention as it is preferably combined with a blown film line or a flat film line for the production of plastic film. The web-shaped material 101, that is to say preferably a plastic web, is guided along a transport direction T onto a contact roller 102 which rotates in the direction R 1 . At contact point 110, the contact roller is placed against a roll 103 (or the roll 103 is placed against contact roll 102). In this contact point 110, the web-shaped material 101 is guided by the contact roller 102 onto the winding 103 and pressed there. The winding 103 is held firmly on the winding shaft 104, the winding shaft 104 rotating in the direction R 2 .

Eine Walze 120 ist drehbar gelagert, wobei die Walze Erhöhungen 121 trägt, die vorzugsweise ringförmig sind. Die Walze 120 kann auf einer Achse drehbar gelagert sein, vorzugsweise ist sie jedoch fest auf einer Welle 122 angeordnet, welche im Schwenkarm 123 drehbar gelagert ist. Der Schwenkarm 123 ist wiederum koaxial zur Rotationsachse der Kontaktwalze schwenkbar gelagert. Die Schwenklagerung 124 des Schwenkarms 123 kann jedoch unabhängig von der Drehlagerung der Kontaktwalze 102 vorgesehen sein. Die Kontaktwalze ist relativ zum nicht gezeigten Maschinengestell drehbar bzw. rotierbar.A roller 120 is rotatably mounted, the roller carrying elevations 121, which are preferably annular. The roller 120 can be rotatably mounted on an axis, but is preferably arranged fixed on a shaft 122 which is rotatably mounted in the swivel arm 123. The swivel arm 123 is in turn pivotally mounted coaxially to the axis of rotation of the contact roller. The pivot bearing 124 of the pivot arm 123 can, however, be provided independently of the rotary bearing of the contact roller 102. The contact roller can be rotated or rotated relative to the machine frame, not shown.

Zur Bereitstellung der Andrückkraft, die durch den Pfeil F symbolisiert ist, ist eine Kraftbereitstellungseinrichtung K vorgesehen, die beispielsweise mit einem Drehlager an dem Maschinengestell und mit einem weiteren Drehlager an dem Schwenkarm 123 angreift. Die Kraftbereitstellungseinrichtung kann durch eine druckluftbetriebene Kolbenzylindereinheit realisiert sein. Gleichfalls ist ein Hydraulikzylinder denkbar. Auch eine elektromotorisch betriebene Kraftbereitstellungseinrichtung ist grundsätzlich denkbar.In order to provide the pressing force, which is symbolized by the arrow F, a force supply device K is provided, for example with a Pivot bearing on the machine frame and with a further pivot bearing on the swivel arm 123. The power supply device can be realized by a piston cylinder unit operated by compressed air. A hydraulic cylinder is also conceivable. A power supply device operated by an electric motor is also fundamentally conceivable.

Die Figur 2 zeigt nun die Ansicht II - II aus der Figur 1, wobei gleiche Bauteile mit gleichen Bezugszeichen versehen sind. In dieser Ansicht ist jedoch erkennbar, dass das bahnförmige Material aus drei Einzelbahnen 101, 101' und 101" besteht und damit auf separaten Wickeln 103, 105 und 106 aufgewickelt wird. Dennoch werden diese Einzelbahnen über die einzige Kontaktwalze 102 zugeführt. Zu erkennen ist ebenfalls, dass die Walze 120 insgesamt vier Erhöhungen 121, 131, 141 und 151 trägt, wobei die äußeren Erhöhungen 121 und 151 an jeweils einen Rand des Wickels 103 bzw. 106 angestellt sind. Die mittleren Erhöhungen 131 und 141 sind jedoch an den Rändern von jeweils zwei Wickeln angestellt. Die Erhöhung 131 ist somit an den Rändern der Wickel 103 und 105 angestellt, wogegen die Erhöhung 141 an den Rändern der Wickel 105 und 106 angestellt ist.The Figure 2 now shows the view II - II from the Figure 1 , the same components being provided with the same reference numerals. In this view, however, it can be seen that the web-shaped material consists of three individual webs 101, 101 'and 101 "and is therefore wound up on separate reels 103, 105 and 106. Nevertheless, these individual webs are fed in via the single contact roller 102. It can also be seen that the roller 120 carries a total of four bumps 121, 131, 141 and 151, the outer bumps 121 and 151 being positioned at one edge of the roll 103 and 106. The central bumps 131 and 141 are, however, on the edges of each two coils are set in. The elevation 131 is thus placed on the edges of the coils 103 and 105, whereas the elevation 141 is set on the edges of the coils 105 and 106.

Im Zusammenhang mit den Figuren 3 und 4 wird nun ein weiteres Ausführungsbeispiel der Erfindung erläutert. Hierbei ist eine Traverse 301 vorgesehen, die, um eine möglichst große Biegesteifigkeit zu gewährleisten, beispielsweise als Doppel-T-Träger ausgestaltet ist. Die Traverse 301 trägt eine Schiene 302, auf welcher Schlitten 303 verschiebbar gelagert sind. Diese Verschiebbarkeit ist durch die Doppelpfeile 304 angedeutet. Auf jeden Schlitten sind Tragstützen 305 aufgebaut, in welchen eine Rolle 306 drehbar gelagert ist.In connection with the Figures 3 and 4 Another embodiment of the invention will now be explained. In this case, a traverse 301 is provided, which is designed, for example, as a double-T beam in order to ensure the greatest possible rigidity. The cross member 301 carries a rail 302 on which slides 303 are slidably mounted. This displaceability is indicated by the double arrows 304. Support supports 305 are built onto each slide, in which a roller 306 is rotatably mounted.

Betrachtet man nun die Figuren 1 und 2, so kann der Aufbau gemäß der Figuren 3 und 4 die Walze 120 mit den Erhöhungen 121, 131, 141 und 151 sowie die Welle ersetzen. Somit kann die Traverse 301 direkt an den Schwenkarmen 123 befestigt sein. Die Rollen 306 übernehmen dann die Funktion der Erhöhungen 121, 131, 141 und 151, d. h., diese Rollen 306 sind an die Ränder der Wickel 103, 105 und 106 anstellbar, um den Kantenaufbau zu vermeiden.Now consider that Figures 1 and 2 , the structure according to the Figures 3 and 4 replace the roller 120 with the elevations 121, 131, 141 and 151 and the shaft. The cross member 301 can thus be attached directly to the swivel arms 123. The rollers 306 then take over the function of the elevations 121, 131, 141 and 151, ie these rollers 306 can be adjusted against the edges of the windings 103, 105 and 106 in order to avoid the edge build-up.

Insgesamt ist zu beachten, dass die Erhöhungen 121, 131, 141 und 151 sowie die Rollen 306 eine im Vergleich zu ihrem Durchmesser geringe Breite aufweisen. So kann das Verhältnis Durchmesser zu Breite mindestens 2 : 1 betragen, vorzugsweise jedoch 3 : 1. Das bedeutet, dass die genannten Elemente scheibenartig ausgeführt sind. Der Übergang von der Umfangsfläche zu den Stirnseiten der Erhöhungen bzw. Rollen kann abgerundet sein, um Markierungen auf dem bahnförmigen Material, die bei einer eckigen Ausgestaltung entstehen können, zu vermeiden. Solche Markierungen stellen zumindest bei Kunststofffolien eine Beschädigung dar. Bezugszeichenliste 100 Wickelvorrichtung 101, 101', 101" Bahnförmiges Material 102 Kontaktwalze 103 Wickel 104 Wickelwelle 110 Kontaktpunkt 120 Walze 121 Erhöhungen 122 Welle 123 Schwenkarm 124 Schwenklagerung 131 Erhöhung 141 Erhöhung 151 Erhöhung 301 Traverse 302 Schiene 303 Schlitten 304 Doppelpfeile 305 Tragstützen 306 Rolle F Pfeil zur Symbolisierung der Andrückkraft R1, R2 Rotationsrichtung T Transportrichtung K Kraftbereitstellungseinrichtung Overall, it should be noted that the elevations 121, 131, 141 and 151 and the rollers 306 have a narrow width compared to their diameter. The ratio of diameter to width can thus be at least 2: 1, but preferably 3: 1. This means that the elements mentioned are designed like disks. The transition from the peripheral surface to the end faces of the elevations or rollers can be rounded off in order to avoid markings on the web-like material which can arise in the case of an angular configuration. Such markings represent damage, at least in the case of plastic films.
