Description

Die Erfindung betrifft eine Abrollvorrichtung für Wickelrollen, mit einem Lagerelement, zwei am Lagerelement angeordneten Tragelementen zur beidseitigen drehbaren Halterung einer Wickelrolle, wobei die beiden Tragelemente entlang des Lagerelementes derart bewegbar gelagert sind, dass sich bei relativer Bewegung der beiden Tragelemente zueinander der Abstand zwischen diesen ändert, und einer Antriebseinrichtung zur Bewegung der beiden Tragelemente entlang des Lagerelementes.The invention relates to a rolling device for winding rolls, with a bearing element, two arranged on the bearing element supporting elements for two-sided rotatable mounting a winding roll, wherein the two support elements are mounted so movable along the bearing element, that changes relative to each other the movement between the two support elements between them , and a drive device for moving the two support elements along the bearing element.

Materialbahnen, insbesondere Papierbahnen in der papierverarbeitenden Industrie, werden im allgemeinen in Form großer, schwerer Wickelrollen angeliefert und bevorratet. Bei der Verarbeitung solcher Materialbahnen auf entsprechenden Maschinen werden diese Bahnen von den Wickelrollen abgezogen. Diese Verarbeitungsmaschinen sind deshalb mit entsprechenden Abrollvorrichtungen versehen, in denen die Wickelrollen an zwei an einem Lagerelement angeordneten Tragelementen beiderseitig drehbar gehaltert werden. Dabei wird gewöhnlich die Wickelrolle während des Abwickelns achslos zwischen den beiden Tragelementen eingespannt und von diesen gehalten. Zum Beladen mit einer neuen Wickelrolle, zum Abnehmen des Kerns der Wickelrolle nach vollständiger Abwicklung und zur Einstellung auf verschiedene Rollenbreiten und Justierung der Position in Bezug auf den Materialbahnweg sind die Tragelemente am Lagerelement aufeinander zu und voneinander weg bewegbar gelagert.Material webs, in particular paper webs in the paper processing industry, are generally delivered in the form of large, heavy winding rolls and stored. When processing such material webs on appropriate machines, these webs are removed from the winding rolls. These processing machines are therefore provided with corresponding unwinding devices, in which the winding rollers are rotatably supported on both sides on two bearing elements arranged on a bearing element. In this case, usually the winding roll during unwinding axleless between the two support elements clamped and held by these. For loading with a new winding roll, for removing the core of the winding roll after complete unwinding and adjustment to different roll widths and adjustment of the position with respect to the web path, the support elements are mounted on the bearing element towards and away from each other movably.

Aus der EP 0 909 253 B1 und der entsprechenden US 6,042,047 A , die den nächstkommenden Stand der Technik bilden, von der die vorliegende Erfindung ausgeht, ist eine Abrollvorrichtung für große Papierrollen bekannt, welche ein Gestell mit vier Ständern und zwei Längsträgern sowie mindestens einen Abrollbalken und zwei Tragarme mit jeweils einem Spannkopf aufweist. Die Tragarme sind horizontal quer bewegbar am Abrollbalken gelagert und über eine gemeinsame Gewindespindel derart miteinander gekoppelt, dass ein erster Antrieb für eine gemeinsame gegenläufige Querverstellung der Tragarme und eine daraus resultierende Änderung ihres Abstandes voneinander zur Aufnahme von Wickelrollen mit unterschiedlicher Breite und ein zweiter Antrieb für eine gemeinsame gleichgerichtete Querverstellung der Tragarme ohne Veränderung des Abstandes voneinander zur relativen Positionierung der Wickelrolle in der Verarbeitungsmaschine sorgt. Weiterhin sind für eine Vertikalverstellung des Abrollbalkens beidseitig am Gestell Zugmittel, bevorzugt in Form von Seilen, Riemen oder Ketten, vorgesehen, welche an zwei Spindelmuttern einer zweiten horizontal angeordneten Gewindespindel befestigt sind, so dass der Abrollbalken über die Zugmittel am Gestell aufgehängt ist. Die Rotation dieser zweiten Gewindespindel findet durch einen dritten Antrieb statt.From the EP 0 909 253 B1 and the corresponding US 6,042,047 A , Which form the closest prior art, from which the present invention proceeds, a rolling device for large paper rolls is known, which has a frame with four stands and two side rails and at least one rolling bar and two support arms, each with a clamping head. The support arms are horizontally movable transversely mounted on the rolling bar and coupled together via a common threaded spindle such that a first drive for a common opposite transverse displacement of the support arms and a resulting change in their distance from each other for receiving bobbins with different width and a second drive for a common rectified transverse adjustment of the support arms without changing the distance from each other for relative positioning of the winding roll in the processing machine provides. Furthermore, for a vertical adjustment of the rolling bar on both sides of the frame traction means, preferably in the form of ropes, belts or chains, provided which are attached to two spindle nuts of a second horizontally arranged threaded spindle, so that the rolling bar is suspended on the frame via the traction means.

Zur drehbaren Halterung einer Wickelrolle weist auch diese bekannte Vorrichtung zwei Tragarme auf, die gemeinsam an einer Schwenkwelle gelagert sind. Um Rollen mit unterschiedlicher Breite aufnehmen zu können, ist auch diese bekannte Vorrichtung mit einer Antriebseinrichtung versehen, welche eine Gewindespindel aufweist, mittels derer die Tragarme in Querrichtung bewegbar sind. Ferner sind ein Schwenkantrieb zum Verschwenken der Tragarme um die Schwenkwelle sowie ein weiterer Antrieb vorgesehen, um die Schwenkwelle zusammen mit den Tragarmen horizontal in Bahnlaufrichtung zu verfahren. In der DE 38 25 673 A1 ist eine ähnliche Abrollvorrichtung für große Papierrollen beschrieben, welche zwei Tragarme umfasst, die gemeinsam an einer Schwenkwelle gelagert sind. Die Tragarme sind mit Spannköpfen versehen, welche einfahrbar ausgeführt sind, um neue Wickelrollen aufnehmen zu können.The EP 0 289 749 B1 and the corresponding one US 4,895,314 A disclose a device for unwinding a web of material from a roll, in particular a large paper roll for the paper processing industry. For rotatable mounting of a winding roll, this known device has two support arms, which are mounted together on a pivot shaft. In order to accommodate roles with different widths, this known device is also provided with a drive device which has a threaded spindle, by means of which the support arms are movable in the transverse direction. Furthermore, a Swivel drive for pivoting the support arms about the pivot shaft and a further drive provided to move the pivot shaft together with the support arms horizontally in the web running direction. In the DE 38 25 673 A1 a similar rolling device for large paper rolls is described, which comprises two support arms which are mounted together on a pivot shaft.

Die DE 42 19 518 A1 offenbart eine Vorrichtung zum Zuführen von rollenförmigem Material zu einer Klebevorbereitungsstation. Diese bekannte Vorrichtung, die insbesondere zur Aufnahme abzurollender großer Papierrollen vorgesehen ist, weist ein Gestell mit mindestens vier Ständern auf, die durch zwei Längsträger miteinander verbunden sind. Zwischen den Längsträgern ist mindestens eine in Querrichtung verfahrbare Traverse vorgesehen, an der zwei Tragarme mittels zweier Laufkatzen horizontal quer bewegbar angeordnet sind.The DE 42 19 518 A1 discloses a device for feeding roll-shaped material to an adhesive preparation station. This known device, which is provided in particular for receiving unrolling large paper rolls, has a frame with at least four stands, which are interconnected by two longitudinal members. Between the longitudinal members at least one traverse movable in the transverse direction is provided on the two support arms are arranged horizontally transversely movable by means of two trolleys.

Eine weitere Abrollvorrichtung mit mehreren Zahnrädern und Ketten für die Antriebseinrichtung wird auch in US 4 951 894 offenbart.Another rolling device with multiple gears and chains for the drive device is also in U.S. 4,951,894 disclosed.

Die bekannten Abrollvorrichtungen erfordern insbesondere eine recht aufwendige Antriebseinrichtung, um sämtliche gewünschte Verstellfunktionen realisieren zu können.In particular, the known unwinding devices require a rather complicated drive device in order to be able to realize all desired adjustment functions.

Der Erfindung liegt die Aufgabe zugrunde, in einer Vorrichtung der eingangs genannten Art die Antriebseinrichtung mit einer einfachen Konstruktion zu realisieren, welche gleichwohl sämtliche Verstellmöglichkeiten bietet.The invention has for its object to realize in a device of the type mentioned, the drive device with a simple construction, which nevertheless offers all adjustment options.

Diese Aufgabe wird durch eine Abrollvorrichtung gemäß Anspruch 1 gelöst.This object is achieved by a rolling device according to claim 1.

Die erfindungsgemäße Lösung bietet eine mechanisch einfache und kostengünstige Ausführung der Antriebseinrichtung mit voller Funktionalität einer sog. Pick-Up-Abrollung, welche somit sämtliche Verstellmöglichkeiten bietet. Dies wird erfindungsgemäß dadurch erreicht, dass mindestens ein Zugmittel am Lagerelement angeordnet und entlang des Lagerelementes beweglich gelagert ist und mindestens ein Tragelement wahlweise entlang des Zugmittels bewegt oder gegenüber diesem ortsfest angeordnet werden kann. Hierzu ist an jenem Tragelement mindestens ein Eingriffsmittel vorgesehen, welches das Tragelement am Zugmittel lösbar verriegelt. Dadurch ergibt sich eine mechanische Verankerung des Tragelementes am Zugmittel, welche eine ortsfeste Anordnung des Tragelementes am Zugmittel bewirkt. Zusätzliche Sicherheitsvorkehrungen sind nicht erforderlich, da sich die Tragelemente dann nur noch gemeinsam aufgrund einer Bewegung des Zugmittels entlang des Lagerelementes verfahren lassen und sich somit nicht ungewollt öffnen können. Ist dagegen das Eingriffsmittel gelöst, lässt sich das zugehörige Tragelement gegenüber dem Zugmittel und entlang des Lagerelementes bewegen und somit verstellen, wobei die Verstellung unabhängig von dem anderen Tragelement möglich ist. Dadurch, dass sich durch die Verriegelung am Zugmittel die Tragelemente bei Bewegung des Zugmittels entlang des Lagerelementes nur noch gemeinsam verfahren lassen, ergibt sich als weiterer Vorteil, dass während einer solchen Bewegung der Abstand zwischen den Tragelementen konstant bleibt und sich deshalb eine solche Verstellung auch vorteilhaft für eine Justierung der Position der aufgenommenen Wickelrolle in Bezug auf den gewünschten Materialbahnweg in einer Maschine nutzen lässt. Demnach erlaubt die Erfindung auf konstruktiv besonders einfache, jedoch gleichzeitig wirkungsvolle Weise sowohl die Möglichkeit einer Einstellung auf verschiedene Rollenbreiten als auch der Justierung der Position der aufgenommenen Wickelrolle.The solution according to the invention provides a mechanically simple and cost-effective design of the drive device with full functionality of a so-called pick-up unwinding, which thus offers all possible adjustments. This is inventively achieved in that at least one traction means is arranged on the bearing element and mounted movably along the bearing element and at least one support element optionally moves along the traction means or can be arranged in relation to this stationary. For this purpose, at least one engagement means is provided on that support element, which releasably locks the support element on the traction means. This results in a mechanical anchoring of the support element on the traction means, which causes a stationary arrangement of the support element on the traction means. Additional safety precautions are not required because the support elements can then only be moved together due to a movement of the traction device along the bearing element and thus can not open unintentionally. If, on the other hand, the engagement means are released, the associated support element can be moved relative to the traction means and along the bearing element and thus adjusted, wherein the adjustment is possible independently of the other support element. Due to the fact that the supporting elements can only be moved together by the locking mechanism on the traction element when the traction element moves along the bearing element, it is a further advantage that the distance between the carrier elements remains constant during such a movement and therefore such an adjustment is also advantageous for an adjustment of the position of the recorded winding roll with respect to the desired web path in a machine can be used. Accordingly, the invention allows for structurally particularly simple, but at the same time effective way both the possibility of adjustment to different roll widths as well as the adjustment of the position of the recorded winding roll.

Die Erfindung benötigt im wesentlichen nur einfache und kostengünstige mechanische Elemente. Mit Hilfe der Erfindung kann gegenüber herkömmlichen Konstruktionen eine wesentliche Kostenreduzierung desweiteren insbesondere in einer Grundausführung erzielt werden, in der eine manuelle Bedienung auf einfache Weise möglich ist und auf jegliche Automatisierung und die damit verbundene kostenintensive Montage und Wartung von elektronischen Bauteilen verzichtet wird. Gleichwohl bietet die erfindungsgemäße Konstruktion den Vorteil einer Aufrüstung bis zur vollständigen Automatisierung. Die zur Zeit am häufigsten geforderte Automatisierungsstufe bildet die automatische Seitenkantensteuerung, wodurch die Position der bereits aufgenommenen Wickelrolle in Bezug auf den Materialbahnweg justiert wird; während die Aufnahme der Wickelrolle und die hierfür erforderliche Einstellung des Abstandes der Tragelemente voneinander manuell stattfindet. Eine solche automatische Seitenkantenregelung lässt sich mit der Erfindung unter geringem Aufwand adaptieren, da nur ein einziger Antrieb benötigt wird.The invention essentially requires only simple and inexpensive mechanical elements. With the help of the invention can over conventional constructions Furthermore, a substantial cost reduction can be achieved, in particular in a basic version in which a manual operation is possible in a simple manner and is dispensed with any automation and the associated costly installation and maintenance of electronic components. Nevertheless, the construction according to the invention offers the advantage of upgrading to complete automation. The currently most commonly required automation level is automatic side edge control, which adjusts the position of the already taken up take-up roll with respect to the web path; while the recording of the winding roll and the necessary adjustment of the distance of the support elements from each other takes place manually. Such an automatic side edge control can be adapted with the invention with little effort, since only a single drive is needed.

Zwar offenbart die EP 0 909 253 B1 die Verwendung von Zugmitteln, jedoch sind diese anders als bei der Erfindung für eine hängende Lagerung des Abrollbalkens am Gestell vorgesehen. Demgegenüber ist bei diesem Stand der Technik für die Querverstellung der beiden Tragarme eine Gewindespindel vorgesehen, die von einem Motor angetrieben wird und im Bereich der ersten Tragarmlagerung und der zweiten Tragarmlagerung gegenläufige Steigungen aufweist. Eine individuelle Verstellung der Tragarme, wie mit der erfindungsgemäßen Konstruktion möglich, ist in diesem Stand der Technik nicht vorgesehen und auch wegen der gegenläufigen Steigung auf der Gewindespindel gar nicht möglich. Demnach kann dieser Stand der Technik die Erfindung auch nicht nahe legen.Although reveals the EP 0 909 253 B1 the use of traction means, but these are provided differently than in the invention for a hanging storage of the rolling bar on the frame. In contrast, a threaded spindle is provided in this prior art for the transverse adjustment of the two support arms, which is driven by a motor and in the region of the first Tragarmlagerung and the second Tragarmlagerung has opposite slopes. An individual adjustment of the support arms, as possible with the construction according to the invention is not provided in this prior art and not possible because of the opposite pitch on the threaded spindle. Accordingly, this prior art also does not suggest the invention.

Bevorzugte Ausführungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and further developments of the invention are specified in the dependent claims.

So lässt sich die Erfindung bevorzugt in zwei Varianten ausführen, und zwar in einer ersten Variante, bei welcher das eine der beiden Tragelemente mit dem rotierbar gelagerten Eingriffsmittel versehen und das andere Tragelement mit dem Zugmittel fest gekoppelt ist, und in einer alternativen zweiten Variante, bei welcher an jedem der Tragelemente mindestens ein rotierbar gelagertes Eingriffsmittel vorgesehen ist. Die letztgenannte zweite Variante erlaubt mehr Flexibilität bei der Einstellung auf verschiedene Rollenbreiten. Grundsätzlich lassen sich aber sämtliche Verstellmöglichkeiten auch mit der erstgenannten Variante realisieren.Thus, the invention can be carried out preferably in two variants, in a first variant in which one of the two support elements provided with the rotatably mounted engagement means and the other support member is fixedly coupled to the traction means, and in an alternative second variant, at which on each of the support elements at least one rotatably mounted engagement means is provided. The latter second variant allows more flexibility in setting to different roll widths. In principle, however, all adjustment options can also be realized with the first-mentioned variant.

Eine besonders bevorzugte Ausführung der Erfindung zeichnet sich dadurch aus, dass das Eingriffsmittel um eine winklig, vorzugsweise etwa rechtwinklig, zur Bewegungsrichtung des Zugmittels verlaufende Drehachse rotierbar gelagert ist und sich mit dem Zugmittel derart in Eingriff befindet, dass das Eingriffsmittel bei Rotation sich am Zugmittel entlang bewegt und dadurch eine Relativbewegung des Tragelementes gegeben ist und bei Stillstand das Tragelement am Zugmittel verriegelt. Die drehbare Lagerung des Eingriffsmittels lässt demnach eine Bewegung des Tragelementes gegenüber dem Zugmittel zu, wobei das Eingriffsmittel an dem Zugmittel entlang läuft. Wird das Eingriffsmittel durch äußere Einwirkung, sei es manuell oder durch einen Antrieb, in Rotation versetzt, führt dies dazu, dass sich das Eingriffsmittel am Zugmittel abstößt und somit das Tragelement gegenüber dem Zugmittel in Bewegung versetzt. Durch Rotation des Eingriffsmittels und der dadurch bedingten Bewegung des Tragelementes gegenüber dem Zugmittel lässt sich der Abstand dieses Tragelementes gegenüber dem anderen Tragelement verändern und auf die Breite der aufzunehmenden Wickelrolle auf einfache Weise einstellen. Demgegenüber wird durch Verbringen des Eingriffsmittels in den Stillstand dieses und somit das Tragelement am Zugmittel verriegelt, was insbesondere nach Aufnahme einer Wickelrolle stattfindet. Demnach wird bei dieser Ausführung die lösbare Verriegelung dadurch realisiert, dass das rotierbar gelagerte Eingriffsmittel wahlweise zum einen frei dreht oder rotierend angetrieben wird und zum anderen für die Verriegelung im Stillstand gehalten wird.A particularly preferred embodiment of the invention is characterized in that the engagement means is rotatably mounted about an axis of rotation, preferably approximately at right angles, to the direction of movement of the traction means and is engaged with the traction means such that the engagement means moves along the traction means during rotation moves and thereby a relative movement of the support element is given and locked at standstill, the support member on the traction means. The rotatable mounting of the engagement means thus allows movement of the support member relative to the traction means, with the engagement means running along the traction means. If the engagement means by external action, be it manually or by a drive, set in rotation, this causes the engagement means repels the traction means and thus set the support member against the traction means in motion. By rotation of the engagement means and the consequent movement of the support member relative to the traction means, the distance of this support member relative to the other support member can be changed and adjusted to the width of the male winding roll in a simple manner. In contrast, by bringing the engagement means in the standstill this and thus the support member is locked to the traction means, which takes place in particular after receiving a winding roll. Accordingly, in this embodiment, the releasable locking is realized in that the rotatably mounted engagement means either on the one hand rotates freely or is driven in rotation and is held to the other for the lock at a standstill.

Bevorzugt ist das Zugmittel als flexibles Zugmittel ausgebildet, welches bei einer Weiterbildung dieser Ausführung endlos umläuft. Auf diese Weise lässt sich das Zugmittel nicht nur konstruktiv besonders einfach ausbilden, sondern auch besonders platzsparend anordnen.Preferably, the traction means is designed as a flexible traction means, which circulates endlessly in a development of this embodiment. In this way, the traction means not only structurally particularly simple form, but also arrange very compact.

Vorzugsweise kann das Eingriffsmittel eine Rolle sein und sich stets ein Abschnitt des Zugmittels mit mindestens einem Abschnitt des Umfanges der Rolle in Eingriff befinden. Für einen besonders wirkungsvollen Eingriff kann die Rolle vom Zugmittel abschnittsweise umschlungen werden.Preferably, the engagement means may be a roller and always a portion of the traction means are engaged with at least a portion of the circumference of the roller. For a particularly effective engagement, the role of the traction means can be wrapped in sections.

Beispielsweise kann das Zugmittel ein Seil oder Riemen sein.For example, the traction means may be a rope or belt.

Alternativ ist es aber auch denkbar, dass das Zugmittel ein Zahnriemen und das Eingriffsmittel ein Zahnrad oder Ritzel ist, dessen Zähne in die Zwischenräume zwischen den Zähnen des Zahnriemens eingreifen.Alternatively, it is also conceivable that the traction means is a toothed belt and the engagement means is a gear or pinion whose teeth engage in the spaces between the teeth of the toothed belt.

Als weitere Alternative ist es denkbar, dass das Zugmittel eine Kette und das Eingriffsmittel ein Zahnrad oder Ritzel ist, dessen Zähne in die Kettenglieder der Kette eingreifen.As a further alternative, it is conceivable that the traction means is a chain and the engagement means is a gear or pinion whose teeth engage in the chain links of the chain.

Zweckmäßigerweise sollte das Zugmittel zumindest abschnittsweise entlang einer im wesentlichen geraden Linie bewegbar gelagert sein. Da gewöhnlich die beiden Tragelemente zur beidseitigen drehbaren Halterung einer Wickelrolle um ihre Drehachse vorgesehen sind, sollte jene im wesentlichen gerade Linie, entlang derer das Zugmittel zumindest abschnittsweise bewegbar ist, zweckmäßigerweise etwa parallel zu jener Drehachse gerichtet sein.Conveniently, the traction means should be at least partially movable along a substantially straight line. Since usually the two support members are provided for two-sided rotatable mounting a winding roll about its axis of rotation, should be directed approximately parallel to the axis of rotation about that substantially straight line along which the traction means is at least partially movable.

Insbesondere für einen fernbedienten oder automatisierten Betrieb ist es von Vorteil, wenn die Antriebseinrichtung mindestens einen am Lagerelement angeordneten Antrieb für eine angetriebene Bewegung des Zugmittels entlang des Lagerelementes aufweist. Alternativ oder zusätzlich kann die Antriebseinrichtung für eine angetriebene Rotation mindestens eines Eingriffsmittels mindestens einen am zugehörigen Tragelement angeordneten Antrieb aufweisen, welcher bei einer Weiterbildung dieser Ausführung eine Bremse aufweist, um das Eingriffsmittel bei Bedarf im Stillstand halten zu können. Zweckmäßigerweise werden als derartige Antriebe Elektromotoren verwendet.In particular, for a remote-controlled or automated operation, it is advantageous if the drive device has at least one arranged on the bearing element drive for a driven movement of the traction means along the bearing element. Alternatively or additionally, the drive device for a driven rotation of at least one engagement means comprise at least one arranged on the associated support member drive, which has a brake in a development of this embodiment to hold the engagement means when needed at a standstill. Expediently, electric motors are used as such drives.

Bevorzugt weisen die Tragelemente jeweils einen Lagerzapfen zur drehbaren Lagerung einer Wickelrolle auf, wobei die Lagerzapfen mit ihren freien Enden aufeinander zu gerichtet und koaxial zueinander angeordnet sind. Bei einer Weiterbildung dieser Ausführung sind die Lagerzapfen zum Einstecken oder Einfahren in einen Kern oder eine Hülse einer Wickelrolle ausgebildet. Bei den Lagerzapfen handelt es sich somit um Führungsköpfe oder können Teil von am freien Ende der Tragelemente ausgebildeten Führungsköpfen sein.Preferably, the support members each have a bearing pin for rotatably supporting a winding roll, wherein the bearing pins are directed with their free ends facing each other and coaxial with each other. In a further development of this embodiment, the journals are designed for insertion or retraction into a core or a sleeve of a winding roll. The bearing pins are thus guide heads or can be part of guide heads formed at the free end of the support elements.

Zweckmäßigerweise sind die Tragelemente als Tragarme ausgebildet, welche gewöhnlich am Lagerelement hängend angeordnet sind. An ihrem freien Ende können die Tragarme jeweils mit einem Lagermittel zur drehbaren Lagerung einer Seite einer Wickelrolle versehen sein, wobei es sich bei diesem Lagermittel gewöhnlich um den zuvor erwähnten Lagerzapfen handelt. An dieser Stelle sei noch der Vollständigkeit halber angemerkt, dass die Halterung der Wickelrolle an den Tragelementen ggf. nicht nur aufgrund der abstandsveränderlichen Verstellung der Tragelemente, sondern durch zusätzliche konstruktive Maßnahme lösbar ist, um die Wickelrollen auf einfache Weise auswechseln zu können.Conveniently, the support elements are designed as support arms, which are usually arranged hanging on the bearing element. At its free end, the support arms can each be provided with a bearing means for rotatably supporting one side of a winding roll, wherein this bearing means is usually the bearing journal mentioned above. At this point, it should be noted for the sake of completeness that the holder of the winding roll on the support elements, if necessary, not only due to the distance variable adjustment of the support elements, but by additional structural means is solvable to replace the bobbins in a simple manner.

Bevorzugt ist das Lagerelement als Traverse ausgebildet, welche im wesentlichen horizontal angeordnet ist.Preferably, the bearing element is designed as a traverse, which is arranged substantially horizontally.

Ferner ist vorzugsweise ein Gestell vorgesehen, an dem das Lagerelement angeordnet ist. Bei einer zweckmäßigen Weiterbildung dieser Ausführung ist das Lagerelement höhenverstellbar am Gestell gelagert, wozu bevorzugt eine Hubantriebseinrichtung vorgesehen werden kann. Als Hubantriebseinrichtung kann beispielsweise eine hydraulische oder pneumatische Kolben-Zylinder-Anordnung verwendet werden. Somit lässt sich bei dieser Ausführung die von den Tragelementen gehaltene Wickelrolle nicht nur in gewöhnlich mit der Horizontalen etwa übereinstimmender axialer Richtung, sondern zusätzlich auch in vertikaler Richtung verstellen.Furthermore, a frame is preferably provided, on which the bearing element is arranged. In an expedient development of this embodiment, the bearing element is height-adjustable mounted on the frame, for which purpose preferably a Hubantriebseinrichtung can be provided. As a lifting drive means, for example, a hydraulic or pneumatic piston-cylinder arrangement can be used. Thus, in this embodiment, the winding roll held by the support elements can not only be adjusted in the usual horizontal direction with the horizontal, but also in the vertical direction.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der beiliegenden Figur näher erläutert, in welcher eine bevorzugte Ausführung der erfindungsgemäßen Abrollvorrichtung schematisch gezeigt ist.Hereinafter, a preferred embodiment of the invention will be explained in more detail with reference to the accompanying figure, in which a preferred embodiment of the unwinding device according to the invention is shown schematically.

Die in der beiliegenden Figur schematisch dargestellte bevorzugte Ausführung einer Abrollvorrichtung für Wickelrollen, welche bevorzugt in der papierverarbeitenden Industrie zum Einsatz kommt, um Papierbahnen zur weiteren Verarbeitung von einer Wickelrolle abzuziehen, weist ein Gestell auf, von dem in der beiliegenden Figur nur zwei voneinander beabstandete, vertikale Ständer 2 abschnittsweise schematisch gezeigt sind. Gewöhnlich sind zur Bildung des Gestells vier solcher vertikalen Ständer vorgesehen, welche über in den Figuren ebenfalls nicht dargestellte Längs- und Querträger miteinander verbunden sind.The preferred embodiment shown schematically in the accompanying figure of an unrolling device for winding rolls, which is preferably used in the paper processing industry to withdraw paper webs for further processing of a winding roll, has a frame, of which only two spaced apart in the accompanying figure, vertical stand 2 sections are shown schematically schematically. Usually, four such vertical uprights are provided for the formation of the frame, which are connected to each other in the figures also not shown longitudinal and transverse members.

Wie die Figur erkennen lässt, ist zwischen zwei voneinander beabstandeten, vertikalen Ständern 2 eine Quertraverse 4 angeordnet, die sich etwa horizontal erstreckt. Mit ihren beiden seitlichen Enden 4a ist die Quertraverse 4 im dargestellten Ausführungsbeispiel in vertikaler Richtung bewegbar an den jeweiligen Ständern 2 gelagert, wobei die Lagerung im dargestellten Ausführungsbeispiel durch ein in vertikaler Richtung wirkendes Schienenführungssystem gebildet wird, das in der Figur schematisch dargestellt und mit dem Bezugszeichen "6" gekennzeichnet ist. Für die vertikale Höheverstellung sind als Antriebe im dargestellten Ausführungsbeispiel pneumatische oder hydraulische Kolben-ZylinderAnordnungen 8 vorgesehen, die sich mit ihrem einen Ende, vorzugsweise dem Zylinder, am zugehörigen Ständer 2 abstützen und mit ihrem anderen Ende, vorzugsweise dem Ende der Kolbenstange, das entsprechende Ende 4a der Quertraverse 4 beaufschlagen.As can be seen from the figure, between two spaced-apart, vertical uprights 2 a cross-beam 4 is arranged, which extends approximately horizontally. With its two lateral ends 4a, the cross-beam 4 is mounted in the illustrated embodiment in the vertical direction movable on the respective uprights 2, wherein the bearing is formed in the illustrated embodiment by a vertically acting rail guide system, shown schematically in the figure and with the reference numeral "6" is marked. For the vertical height adjustment are provided as drives in the illustrated embodiment, pneumatic or hydraulic piston-cylinder assemblies 8, which are supported with its one end, preferably the cylinder on the associated stand 2 and with its other end, preferably the end of the piston rod, the corresponding end 4a act on the cross-beam 4.

Wie die Figur ferner erkennen lässt, sind an der Quertraverse 4 im dargestellten Ausführungsbeispiel zwei Tragarme 10 hängend angeordnet. Die Tragarme 10 dienen zur lösbaren Halterung einer in der Figur nicht dargestellten Wickelrolle. Hierzu ist jeder Tragarm 10 an seinem unteren freien Ende 10a mit einem Führungskopf 12 versehen, der einen Lagerzapfen 14 aufweist. Die Führungsköpfe 12 dienen zum lösbaren Eingriff mit einer Hülse oder einem Kern einer zu halternden Wickelrolle, indem der Lagerzapfen 14 in die offene Seite der Hülse oder des Kerns der zu halternden Wickelrolle eingeführt oder gesteckt wird. Zur Halterung der Wickelrolle nehmen somit die beiden Tragarme 10 die Wickelrolle zwischen sich auf und haltern die Wickelrolle an ihren beiden Seiten. Dabei gewährleisten die Lagerzapfen 14 eine drehbare Lagerung der Wickelrolle um eine Achse 16, wozu ferner auch der Lagerzapfen 14 oder sogar der gesamte Führungskopf 12 an jeweiligen Tragarm 10 entsprechend drehbar gelagert sein kann. Da die Wickelrolle zwischen den Tragarmen 10 aufgenommen wird, sind die Führungsköpfe 12 mit ihren Lagerzapfen 14 aufeinander zu gerichtet und koaxial zueinander angeordnet, indem ihre Rotationsachsen gemeinsam auf der gemeinsamen Achse 16 liegen, welche bei Halterung einer Wickelrolle mit deren Rotationsachse im wesentlichen zusammenfällt.As the figure further reveals, two support arms 10 are arranged hanging on the cross-beam 4 in the illustrated embodiment. The support arms 10 are used for releasably supporting a winding roller, not shown in the figure. For this purpose, each support arm 10 is provided at its lower free end 10 a with a guide head 12 having a bearing pin 14. The guide heads 12 serve for releasable engagement with a sleeve or a core of a holder to be held Winding roll by the bearing pin 14 is inserted or inserted into the open side of the sleeve or the core of the wound roll to be held. For holding the winding roll thus take the two support arms 10, the winding roll between them and support the winding roll on both sides. In this case, the bearing pins 14 ensure a rotatable mounting of the winding roll about an axis 16, to which also also the bearing pin 14 or even the entire guide head 12 may be rotatably supported on respective support arm 10. Since the winding roll is received between the support arms 10, the guide heads 12 are directed with their bearing pin 14 toward each other and arranged coaxially to each other by their axes of rotation together on the common axis 16, which coincides with a rotation of the winding roll substantially.

Zum Abnehmen des Kerns der Wickelrolle nach vollständiger Abwicklung, zum anschließenden Beladen der Vorrichtung mit einer neuen Wickelrolle und zur Einstellung auf die Breite der verwendeten Wickelrolle muss der Abstand zwischen den beiden Tragarmen 10 veränderlich sein, um die Lagerzapfen 14 vom Kern der verbrauchten Wickelrolle zu lösen und ungehindert eine neue Wickelrolle zwischen den Tragarmen 10 zu platzieren. Deshalb sind die Tragarme 10 an der Quertraverse 4 quer verschiebbar gelagert. Hierzu ist die Quertraverse 4 mit einem Führungsschienensystem versehen, das in der Figur schematisch dargestellt und mit dem Bezugszeichen "18" gekennzeichnet ist. Die Tragarme 10 sind mit ihrem zur Quertraverse 4 benachbarten oberen Ende 10b an diesem Führungsschienensystem 18 hängend gelagert, welches eine Bewegung der Tragarme 10 in Richtung der in der Figur dargestellten Pfeile A und somit etwa horizontal und quer zu deren Längserstreckung entlang der Quertraverse 4 erlaubt.To remove the core of the winding roll after complete settlement, for subsequent loading of the device with a new winding roll and to adjust to the width of the winding roll used, the distance between the two support arms 10 must be variable in order to release the bearing pin 14 from the core of the used winding roll and unhindered to place a new winding roll between the support arms 10. Therefore, the support arms 10 are mounted transversely displaceable on the cross-beam 4. For this purpose, the cross-beam 4 is provided with a guide rail system, which is shown schematically in the figure and designated by the reference numeral "18". The support arms 10 are mounted with its adjacent to the cross-beam 4 upper end 10b on this guide rail system 18 hanging, which allows movement of the support arms 10 in the direction of the arrows A shown in the figure and thus approximately horizontally and transversely to the longitudinal extent along the cross-beam 4.

Die Länge der Quertraverse 4 und der daraus resultierende Abstand der beiden Ständer 2 wird durch die gewünschte maximale Breite der zu verwendenden Wickelrolle, auch als Arbeitsbreite bezeichnet, bestimmt.The length of the cross-beam 4 and the resulting distance between the two stands 2 is determined by the desired maximum width of the winding roll to be used, also referred to as the working width.

Während für das Beladen mit einer neuen Wickelrolle und das Abnehmen des Kerns einer verbrauchten Wickelrolle der Abstand zwischen den Tragarmen 10 entsprechend verändert werden muss, ist eine Änderung des Abstandes zwischen den Tragarmen 10 gerade dann nicht gewünscht, wenn die Wickelrolle an den Tragarmen 10 gehaltert ist. Bereits aus Gründen der Sicherzeit dürfen sich dann die Tragarme 10 nicht ungewollt öffnen lassen. Außerdem muss zur Justierung der Position in Bezug auf einen gewünschten Materialbahnweg für die Weiterverarbeitung des von der Wickelrolle abzuziehenden Materials eine Verstellung der Wickelrolle in axialer Richtung möglich sein, wenn diese bereits an den Tragarmen 10 gehaltert ist. Um diese verschiedenen Verstellmöglichkeiten realisieren zu können, ist eine besondere Antriebseinrichtung vorgesehen, die nachfolgend im einzelnen erläutert wird.While for loading with a new winding roll and the removal of the core of a used winding roll, the distance between the support arms 10th must be changed accordingly, a change in the distance between the support arms 10 just then not desired when the winding roll is supported on the support arms 10. Already for reasons of safety then the brackets 10 may not be opened unintentionally. In addition, to adjust the position with respect to a desired web path for further processing of the material to be deducted from the winding roll an adjustment of the winding roll in the axial direction must be possible if it is already supported on the support arms 10. In order to realize these different adjustment, a special drive means is provided, which will be explained in detail below.

Einen Bestandteil dieser Antriebsvorrichtung bildet im dargestellten Ausführungsbeispiel eine Kette 20, die an der Quertraverse 4 endlos umlaufend gelagert ist. Wie die Figur erkennen lässt, in der die Kette 20 schematisch als eine punktierte Linie dargestellt ist, erstreckt sich die Kette 20 mit ihren beiden Trums in Längsrichtung der Quertraverse 4. Zur Umlenkung der endlos umlaufenden Kette 20 ist an jedem Ende 4a der Quertraverse 4 eine entsprechende Umlenkrolle 22 drehbar gelagert. Der den Tragarmen 10 benachbarte, untere Trum 20a der Kette 20 wird im dargestellten Ausführungsbeispiel im Bereich des benachbarten Endes 10b beider Tragarme 10 um eine an jenem Ende 10b der Tragarme 10 drehbar gelagerte erste Rolle 24 aus einer im wesentlichen horizontalen Richtung um etwa 90° nach unten in eine im wesentlichen vertikale Richtung auf ein Zahnrad oder Ritzel 26 umgelenkt, das ebenfalls an jenem Ende 10b der Tragarme 10 drehbar gelagert ist. Die in der Figur nicht erkennbaren Zähne des Ritzels 26 greifen in die ebenfalls im einzelnen nicht erkennbaren Kettenglieder der Kette 10 ein, wodurch sich das Ritzel 26 in Eingriff jeweils mit einem Abschnitt des unteren Trums 20a der Kette 20 befindet. Der untere Trum 20a der Kette 20 umschlingt das Ritzel 26 im dargestellten Ausführungsbeispiel um etwa 180° und läuft dann etwa in vertikaler Richtung zu einer ebenfalls an jenem Ende 10b der Tragarme 10 drehbar gelagerten zweiten Rolle 28, wo der Trum 20a wieder in eine etwa horizontale Richtung umgelenkt wird und die Tragarme 10 verlässt. Wie die Figur ferner erkennen lässt, liegen die ersten und zweiten Rollen 24, 28 etwa auf gleicher Höhe in Bezug auf die Quertraverse 4 und gemäß der Darstellung der Figur etwa auf gleicher vertikaler Höhe, während das Ritzel 26 im dargestellten Ausführungsbeispiel unterhalb dieser beiden Rollen 24, 28 liegt, wodurch sich die bereits erwähnte Umschlingung des unteren Trum 20a der Kette 20 um etwa 180° erzielen lässt. Die Drehachsen der Rollen 24, 28 und des Ritzels 26 verlaufen parallel zueinander und sind im dargestellten Ausführungsbeispiel rechtwinklig zur Achse 16 bzw. der Bewegungsrichtung A der Tragarme 10 gerichtet.A part of this drive device forms in the illustrated embodiment, a chain 20 which is mounted on the cross-beam 4 endlessly circulating. As the figure reveals, in which the chain 20 is shown schematically as a dotted line, the chain 20 extends with its two strands in the longitudinal direction of the cross-beam 4. For deflecting the endless circulating chain 20 is at each end 4a of the cross-beam 4 a corresponding guide roller 22 rotatably mounted. The support arms 10 adjacent lower strand 20a of the chain 20 is in the illustrated embodiment in the region of the adjacent end 10b of both arms 10 about a at that end 10b of the support arms 10 rotatably mounted first roller 24 from a substantially horizontal direction by about 90 ° deflected down in a substantially vertical direction to a gear or pinion 26 which is also rotatably mounted at that end 10 b of the support arms 10. The teeth of the pinion 26, which can not be seen in the figure, engage in the chain links of the chain 10 which are likewise not recognizable in detail, as a result of which the pinion 26 is in engagement with a section of the lower run 20a of the chain 20. The lower run 20a of the chain 20 wraps around the pinion 26 in the illustrated embodiment by about 180 ° and then runs approximately in the vertical direction to a also at that end 10b of the support arms 10 rotatably mounted second roller 28, where the strand 20a again in an approximately horizontal Direction is deflected and the support arms 10 leaves. As the figure also shows, the first and second rollers 24, 28 lie approximately at the same height with respect to the cross-beam 4 and according to the representation of the figure approximately at the same vertical height, while the pinion 26 in the illustrated embodiment below these two rollers 24, 28, whereby the already mentioned wrap of the lower run 20a of the chain 20 can be achieved by about 180 °. The axes of rotation of the rollers 24, 28 and the pinion 26 are parallel to each other and are directed in the illustrated embodiment, at right angles to the axis 16 and the direction of movement A of the support arms 10.

Ferner ist eine in der Figur nicht dargestellte Feststelleinrichtung im Bereich des oberen Endes 10b der Tragarme 10 vorgesehen, um das Ritzel 26 im Stillstand arretieren zu können. Bevorzugt ist diese Feststelleinrichtung als Bremse ausgeführt. Durch die Arretierung des Ritzels 26 im Stillstand wird eine Verriegelung des jeweiligen Tragarmes 10 an der Kette 20 bewirkt. Dies hat zur Folge, dass eine Querverstellung des jeweiligen Tragarmes 10 nur noch durch Bewegung der Kette 20 in deren Längsrichtung möglich ist, während der jeweilige Tragarm 10 gegenüber der Kette 20 ortsfest bleibt.Further, a locking device, not shown in the figure in the region of the upper end 10b of the support arms 10 is provided to lock the pinion 26 at a standstill can. Preferably, this locking device is designed as a brake. By locking the pinion 26 at a standstill locking of the respective support arm 10 is effected on the chain 20. This has the consequence that a transverse displacement of the respective support arm 10 is only possible by movement of the chain 20 in the longitudinal direction, while the respective support arm 10 relative to the chain 20 remains stationary.

Die zuvor beschriebene Verriegelung mit Hilfe von in der Figur nicht dargestellten Feststelleinrichtungen bzw. Bremsen ist dann besonders interessant, wenn beide Tragarme 10 an der Kette 20 verriegelt werden. Dies hat nämlich zur Folge, dass der Abstand zwischen den beiden Tragarmen 10 auch dann konstant bleibt, wenn die Kette 20 verstellt wird, was zu einer gemeinsamen Querverstellung der gesamten Anordnung der beiden Tragarme 10 führt. Zusätzliche Sicherheitsvorkehrungen sind nicht erforderlich.The locking described above with the aid of locking devices or brakes, not shown in the figure is then particularly interesting when both support arms 10 are locked to the chain 20. This has the consequence that the distance between the two support arms 10 remains constant even when the chain 20 is adjusted, resulting in a common transverse adjustment of the entire arrangement of the two support arms 10. Additional security is not required.

Die gleichzeitige Verriegelung beider Tragarme 10 ist insbesondere für eine automatische Seitenkantensteuerung von Bedeutung, wodurch die Position der bereits an den Tragarmen 10 gehalterten Wickelrolle in Bezug auf einen definierten Materialbahnweg für die weitere Verarbeitung des von der Wickelrolle abgezogenen Materials justiert wird, wobei die Mittelachse eines solchen Materialbahnweges in der Figur schematisch als strichpunktierte Linie M gekennzeichnet ist. Für eine solche automatische Seitenkantensteuerung muss ein Antrieb für die Kette 20 vorgesehen werden. Bevorzugt wird hierzu ein Elektromotor verwendet, der eine der beiden Umlenkrollen 22 antreibt und an der Quertraverse 4 montiert ist. In der Figur ist ein solcher Antrieb nicht dargestellt.The simultaneous locking of both support arms 10 is particularly important for an automatic side edge control of importance, whereby the position of the content already supported on the support arms 10 wound roll is adjusted with respect to a defined web path for the further processing of the withdrawn from the winding roll material, the center axis of such Material web path in the figure is schematically indicated by a dash-dotted line M. For such an automatic side edge control, a drive for the chain 20 must be provided. Preferably, an electric motor is used for this purpose, which drives one of the two pulleys 22 and is mounted on the cross-beam 4. In the figure, such a drive is not shown.

Insbesondere für die automatische Seitenkantensteuerung ist es ausreichend, die Feststelleinrichtungen bzw. Bremsen so auszuführen, dass sie lediglich manuell bedient werden können. Für das Be- und Entladen muss bei mindestens einem Tragarm 10 die Feststelleinrichtung bzw. Bremse gelöst werden, um für die Abnahme der verbrauchten Wickelrolle und die Aufnahme einer neuen Wickelrolle den Abstand zwischen den beiden Tragarmen 10 zu vergrößern, bevor dann unter Verringerung des Abstandes zwischen den beiden Tragarmen 10 die Lagerzapfen 14 der Führungsköpfe 12 in die beiden offenen Seiten der neuen Wickelrolle eingefahren werden. Für diesen Vorgang sollten bevorzugt die Feststelleinrichtungen bzw. Bremsen an beiden Tragarmen 10 gelöst werden. Nach Aufnahme der neuen Wickelrolle werden die Feststelleinrichtungen bzw. Bremsen wieder aktiviert, um ein unbeabsichtigtes Öffnen der Tragarme 10 zu verhindern.In particular, for the automatic side edge control, it is sufficient to perform the locking devices or brakes so that they can only be operated manually. For loading and unloading at least one support arm 10, the locking device or brake must be solved to increase the distance between the two support arms 10 for the decrease of the used winding roll and the inclusion of a new winding roll, before then reducing the distance between the two support arms 10, the bearing pin 14 of the guide heads 12 are retracted into the two open sides of the new winding roll. For this process, the locking devices or brakes on both support arms 10 should preferably be solved. After receiving the new winding roll the locking devices or brakes are reactivated to prevent inadvertent opening of the support arms 10.

Während des Be- und Entladens kann die Quertraverse 10 mit Hilfe der zuvor beschriebenen Hubantriebseinrichtung 8 in ihrer Höhe verstellt werden. Allerdings kann die Hubantriebseinrichtung 8 auch während des laufenden Betriebes zum Einsatz kommen, um eine Justierung der Position der gehalterten Wickelrolle in vertikaler Richtung in Bezug auf den Materialbahnweg vornehmen zu können.During loading and unloading, the crossbeam 10 can be adjusted in height by means of the previously described lifting drive device 8. However, the Hubantriebseinrichtung 8 can also be used during ongoing operation to make an adjustment of the position of the salaried winding roll in the vertical direction with respect to the web path.

Aus Vorstehendem wird deutlich, dass bei gelösten bzw. deaktivierten Feststelleinrichtungen bzw. Bremsen sich die beiden Tragarme 10 unabhängig voneinander in Querrichtung gemäß Pfeil A verstellen lassen.From the above it is clear that when the locking devices or brakes are released or deactivated, the two support arms 10 can be adjusted independently of one another in the transverse direction according to arrow A.

Für eine vollautomatische Ausführung ist es denkbar, die beiden Ritzel 26 jeweils mit einem eigenen Antrieb zu versehen, der am jeweiligen Tragarm 10 montiert ist. Auch diesbezüglich sollte vorzugsweise ein Elektromotor verwendet werden, der die Achse des jeweiligen Ritzels 26 antreibt. Für eine unabhängige Verstellung sind die Antriebe der Ritzel 26 an den beiden Tragarmen 10 unabhängig voneinander anzusteuern.For a fully automatic embodiment, it is conceivable to provide the two pinions 26 each with its own drive, which is mounted on the respective support arm 10. Also in this regard, an electric motor should preferably be used which drives the axis of the respective pinion 26. For an independent adjustment are the drives of the pinion 26 to the two support arms 10 independently to control.

Abschließend sei noch darauf hingewiesen, dass anstelle einer Kette 20 beispielsweise auch ein Zahnriemen verwendet werden kann, wobei die Zähne der Ritzel 26 in die Lücken zwischen den Zähnen des Zahnriemens eingreifen.Finally, it should be noted that instead of a chain 20, for example, a toothed belt can be used, wherein the teeth of the pinion 26 engage in the gaps between the teeth of the toothed belt.

Alternativ ist es aber auch ebenfalls denkbar, anstelle der Kette 20 einen zahnlosen Riemen und anstelle der Ritzel 26 entsprechende Rollen vorzusehen, wobei allerdings sichergestellt sein muss, dass die Friktion zwischen dem Riemen und den anstelle der Ritzel 26 zu verwendenden Rollen so groß ist, dass kein Schlupf auftritt.Alternatively, however, it is also conceivable to provide instead of the chain 20 a toothless belt and instead of the pinion 26 corresponding rollers, although it must be ensured that the friction between the belt and to be used instead of the pinion 26 rollers is so large that no slippage occurs.

In diesem Zusammenhang sei ferner angemerkt, dass anstelle eines endlos umlaufenden Zugmittels, das in dem zuvor beschriebenen Ausführungsbeispiel als Kette 20 ausgebildet ist, alternativ auch das vorzugsweise als Kette oder Riemen ausgebildete Zugmittel eine endliche Länge besitzen, also endlich sein und mit seinen Enden jeweils an einer der beiden Umlenkrollen 22 angeschlagen sein kann, so dass eine solche Anordnung nach dem Seilwindenprinzip arbeitet.In this context, it should also be noted that instead of an endlessly circulating traction means, which is formed in the above-described embodiment as a chain 20, alternatively, preferably designed as a chain or belt traction means have a finite length, so be finally and with its ends in each case one of the two pulleys 22 may be posted, so that such an arrangement works on the winch principle.

Alternativ zu der zuvor beschriebenen hängenden Anordnung der Tragarme 10 lassen sich noch weitere vorteilhafte Anordnungen realisieren. Beispielsweise ist alternativ eine stehende Anordnung der Tragarme 10 denkbar, wobei die Quertraverse 4 vorzugsweise unterflur angeordnet werden könnte, um eine gestellfreie Anordnung zu realisieren. Bei einer stehenden Anordnung der Tragelemente 10 ist es außerdem denkbar, die Quertraverse 4 am Boden schwenkbar zu lagern, um die gesamte Vorrichtung beispielsweise zwischen einer Rollenaufnahmeposition und einer Arbeits- bzw. Abrollposition verschwenken zu können. Schließlich ist alternativ aber auch eine horizontale Ausrichtung der Tragarme 10 möglich, wobei in diesem Fall die Quertraverse 4 entweder vertikal und/oder horizontal bewegbar oder auch fest gelagert sein kann.As an alternative to the above-described suspended arrangement of the support arms 10, further advantageous arrangements can be realized. For example, a standing arrangement of the support arms 10 is alternatively conceivable, wherein the cross-beam 4 could preferably be arranged below ground to realize a rack-free arrangement. In a vertical arrangement of the support elements 10, it is also conceivable to pivotally support the cross-beam 4 at the bottom in order to pivot the entire device, for example, between a roller receiving position and a working or unwinding position. Finally, alternatively, a horizontal alignment of the support arms 10 is possible, in which case the cross-beam 4 can be either vertically and / or horizontally movable or fixedly mounted.
