Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Ziehen einer Wickelwelle aus einer Materialrolle, umfassend zumindest einen Grundrahmen mit mindestens einer auf der Unterseite des Grundrahmens angeordneten Bodenstütze, und mindestens einer auf der Oberseite des Grundrahmens angeordneten Klemmvorrichtung zum klemmenden Halten der Wickelwelle.The present invention relates to a device for pulling a winding shaft from a roll of material, comprising at least one base frame with at least one floor support arranged on the underside of the base frame, and at least one clamping device arranged on the top of the base frame for holding the winding shaft by clamping.

Wickelwellen werden zum Aufwickeln von endlosem bahnförmigen Material aus Papier, Folie oder Fasern verwendet. Die Wickelwelle bildet dabei den Kern für das Aufspulen oder Aufwickeln von Bahnmaterial zu großen transportfähigen Rollen nach der Herstellung. Auf die Wickelwelle wird oft eine Papp- oder Kunststoffhülse aufgeschoben, auf welche das Bahnmaterial unmittelbar aufgewickelt wird. Zum Spannen weist die Wickelwelle mechanisch, hydraulisch oder pneumatisch betätigbare Spannmittel auf, die nach dem Aufschieben der Hülse den Durchmesser der Wickelwelle vergrößern und die Hülse so fest aufspannen. Nach dem Aufwickeln wird die Wickelwelle aus der Papp- oder Kunststoffhülse herausgezogen. Hierzu weist die Wickelwelle an wenigstens einem Ende mindestens eine Umfangsnut auf, die die Handhabung, die Lagerung und den Transport erleichtern soll.Winding shafts are used to wind up endless web-shaped material made of paper, foil or fibers. The winding shaft forms the core for the winding or winding of web material into large transportable rolls after production. A cardboard or plastic sleeve, onto which the web material is wound directly, is often pushed onto the winding shaft. For tensioning, the winding shaft has mechanically, hydraulically or pneumatically actuated clamping means which, after the sleeve has been pushed on, enlarge the diameter of the winding shaft and thus firmly clamp the sleeve. After winding, the winding shaft is pulled out of the cardboard or plastic sleeve. For this purpose, the winding shaft has at least one circumferential groove at at least one end, which is intended to facilitate handling, storage and transport.

Die Wickelwelle kann je nach Breite der Warenbahn ein Gewicht von mehr als 200 kg und eine Länge von über 5 m aufweisen. Insbesondere durch den Wickelvorgang lastet ein hoher Anpressdruck auf der Wickelwelle, die auch bei entspannten Spannmitteln nur mit erhöhtem Kraftaufwand aus der Papp- oder Kunststoffhülse herausgezogen werden kann. Nach dem Stand der Technik weist jede Wickelmaschine eine eigene Vorrichtung zum Entfernen der Wickelwellen auf, die oft schienengebunden ist und daher nicht bei den anderen Wickelmaschinen einsetzbar ist. Das verteuert die Wickelmaschine unnötig.The winding shaft can have a weight of more than 200 kg and a length of over 5 m, depending on the width of the material web. Particularly due to the winding process, a high contact pressure is placed on the winding shaft, which can only be pulled out of the cardboard or plastic sleeve with increased effort, even when the clamping means are relaxed. According to the prior art, each winding machine has one own device for removing the winding shafts, which is often rail-bound and therefore cannot be used with the other winding machines. This makes the winding machine more expensive.

Die DE 102015208122 A1 offenbart einen ortsfest angeordneten Roboterarm, der ausgebildet ist, komplette Wickel und einzelne Wickelwellen in mehreren Achsen zu greifen und in einem begrenzten Radius abzulegen.The DE 102015208122 A1 discloses a stationary robot arm which is designed to grip complete laps and individual winding shafts in several axes and to deposit them in a limited radius.

In der US 3,583,575 A wird ein Wickel mit seiner Stirnseite in eine Aufnahmevorrichtung gelegt und durch Verschwenken der Aufnahmevorrichtung um 90° in eine Position zum weiteren Transport entlang der Längsachse in die Abwickelvorrichtung gebracht.In the U.S. 3,583,575 A a roll is placed with its front side in a receiving device and, by pivoting the receiving device by 90 °, is brought into a position for further transport along the longitudinal axis into the unwinding device.

Die US 7,674,086 B2 zeigt eine Vorrichtung, bei der eine Wickelwelle an einem Ende befestigt wird und der Wickel von der feststehenden Wickelwelle auf einen Dorn gezogen wird.The US 7,674,086 B2 shows a device in which a winding shaft is attached to one end and the winding is drawn from the stationary winding shaft onto a mandrel.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Ziehen von Wickelwellen zu schaffen, die preiswert herstellbar und flexibel für eine Vielzahl von Wickelmaschinen verwendbar ist.The invention is therefore based on the object of creating a device for pulling winding shafts which can be manufactured inexpensively and which can be used flexibly for a large number of winding machines.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale von Anspruch 1. Weitere vorteilhafte Ausführungsformern werden durch die Unteransprüche beansprucht.This object is achieved by the features of claim 1. Further advantageous embodiments are claimed by the subclaims.

Die erfindungsgemäße Vorrichtung zum Ziehen einer Wickelwelle aus einer Materialrolle umfasst zumindest einen Grundrahmen, auf dessen Unterseite mindestens eine Bodenstütze angeordnet ist, und mindestens eine auf der Oberseite des Grundrahmens angeordnete Klemmvorrichtung zum klemmenden Halten der Wickelwelle. Die Erfindung ist dadurch gekennzeichnet, dass der Grundrahmen mindestens eine Aufnahmeöffnung aufweist, die ausgebildet ist, mindestens eine Transportgabel eines Flurförderfahrzeuges aufzunehmen.The device according to the invention for pulling a winding shaft from a roll of material comprises at least one base frame, on the underside of which at least one floor support is arranged, and at least one clamping device arranged on the top of the base frame for holding the winding shaft by clamping. The invention is characterized in that the base frame at least one Has receiving opening which is designed to receive at least one transport fork of an industrial truck.

Die erfindungsgemäße Vorrichtung hat den Vorteil, dass sie unabhängig von einer einzelnen Wickelmaschine verwendet werden kann. Sie ist nicht schienengeführt und kann mit jedem beliebigen Transportfahrzeug, dessen Transportgabeln mit den Aufnahmeöffnungen korrespondieren, verwendet werden. Ein weiterer Vorteil ist die kostengünstige Herstellung, da die Vorrichtung kein eigenes Antriebs- oder Fahrsystem aufweist. Die Kombination mit einem schon vorhandenen Flurförderfahrzeug macht die Vorrichtung sehr flexibel, preiswert und kompakt.The device according to the invention has the advantage that it can be used independently of a single winding machine. It is not rail-guided and can be used with any transport vehicle whose transport forks correspond to the receiving openings. Another advantage is the cost-effective production, since the device does not have its own drive or driving system. The combination with an already existing industrial truck makes the device very flexible, inexpensive and compact.

Mit weiterem Vorteil weist der Grundrahmen zwei Aufnahmeöffnungen auf, die beabstandet zueinander angeordnet sind. Damit ist eine sichere formschlüssige Führung der Vorrichtung auf den Transportgabeln eines Flurförderfahrzeuges gewährleistet.With a further advantage, the base frame has two receiving openings which are arranged at a distance from one another. This ensures a secure, form-fitting guidance of the device on the transport forks of an industrial truck.

Vorzugsweise weist die mindestens eine Klemmvorrichtung einen Grundkörper und einen Deckel auf, die mittels Scharnier beweglich verbunden sind. Durch das drehgelenkige Aufklappen des Deckels wird die Klemmvorrichtung geöffnet und kann zumindest einen Schaft oder einen Teil der Wickelwelle aufnehmen.The at least one clamping device preferably has a base body and a cover which are movably connected by means of a hinge. The pivoting opening of the cover opens the clamping device and can accommodate at least one shaft or part of the winding shaft.

Dabei weisen der Grundkörper und der Deckel jeweils eine halbe Zylinderbohrung auf, die bei verschlossener Klemmvorrichtung einen zylindrischen Hohlraum bilden. Mittels Flansch und lösbarer Spannvorrichtung ist die Klemmvorrichtung verschließbar und nimmt somit klemmend zumindest ein Ende der Wickelwelle auf.The base body and the cover each have a half cylinder bore which, when the clamping device is closed, form a cylindrical cavity. The clamping device can be closed by means of a flange and a releasable clamping device and thus holds at least one end of the winding shaft in a clamping manner.

Dadurch, dass auf der Oberseite des Grundrahmens zwei Klemmvorrichtungen beabstandet zueinander angeordnet sind, deren Längsachsen der zylindrischen Hohlräume miteinander fluchten, kann die Wickelwelle an zwei Punkten klemmend gehalten werden, so dass die Verbiegung der Wickelwelle aufgrund ihres Eigengewichtes reduziert wird. Die zwei mit Abstand zueinander angeordneten Klemmvorrichtungen haben gegenüber einer einteiligen langen Klemmvorrichtung den Vorteil der kostengünstigen Herstellung und der Gewichtseinsparung, da die Klemmvorrichtung - um Beschädigungen an der Wickelwelle zu vermeiden - aus einem weichen Werkstoff wie Kupfer oder Bronze hergestellt werden, was relativ teuer ist.Because two clamping devices are arranged at a distance from one another on the upper side of the base frame, their Longitudinal axes of the cylindrical cavities are aligned with one another, the winding shaft can be held clamped at two points, so that the bending of the winding shaft due to its own weight is reduced. The two spaced apart clamping devices have the advantage over a one-piece long clamping device that they are inexpensive to manufacture and save weight, since the clamping devices - to avoid damage to the winding shaft - are made of a soft material such as copper or bronze, which is relatively expensive.

Eine bevorzugte Ausführungsform sieht vor, dass zumindest eine Klemmvorrichtung an dem Deckel eine Öffnung mit einem Vorsprung aufweist. Die Öffnung ist ausgebildet, einen Teil eines Endes der Wickelwelle während der ersten Phase des Herausziehens aufzunehmen.A preferred embodiment provides that at least one clamping device on the cover has an opening with a projection. The opening is configured to receive part of one end of the winding shaft during the first phase of extraction.

Der Vorsprung dagegen ist ausgebildet, in eine Nut der Wickelwelle einzugreifen. Über den Formschluss des Vorsprunges in der Nut der Wickelwelle erfolgt das erste Herausziehen der Wickelwelle aus der Materialrolle. Dabei ist die Wickelwelle aber noch nicht geklemmt und könnte durch ihr Eigengewicht auf den Boden fallen.The projection, on the other hand, is designed to engage in a groove in the winding shaft. The first pulling out of the winding shaft from the roll of material takes place via the positive fit of the projection in the groove of the winding shaft. The winding shaft is not yet clamped and its own weight could cause it to fall to the floor.

Erst in der zweiten Phase des Herausziehens, wenn die Wickelwelle durch die Klemmvorrichtungen klemmend gehalten wird, kann sie vollständig aus der Materialrolle herausgezogen werden. Das Anfahren des Flurförderfahrzeuges wird durch einen Anschlag erleichtert, der im Bereich einer Außenkante des Grundrahmens angeordnet ist, die der Klemmvorrichtung mit der Öffnung und dem Vorsprung gegenüberliegt. Der Anschlag wirkt dabei mit einer Stirnfläche der Wickelwelle zusammen.Only in the second phase of pulling out, when the winding shaft is held clamped by the clamping devices, can it be pulled completely out of the roll of material. The starting of the industrial truck is facilitated by a stop which is arranged in the area of an outer edge of the base frame which is opposite the clamping device with the opening and the projection. The stop interacts with an end face of the winding shaft.

Die Aufnahmeöffnungen 3 weisen jeweils mindestens ein Spannelement 4 auf, mit dem eine lösbare klemmende Befestigung zwischen der Transportgabel 34 und dem Grundrahmen 1 herstellbar ist.The inventive device 100 according to Figure 1 has a base frame 1, which has at least one floor support 2 on its underside for placing and storing the device 100 on the floor, a pallet or a shelf storage location. In this exemplary embodiment, the base frame 1 has two floor supports 2 which are designed as angled sheet metal. Furthermore, the base frame 1 has at least one receiving opening 3, into which the gripping tools or transport forks 34 of an industrial truck 33 can engage. In this exemplary embodiment, two receiving openings 3 are arranged below the base frame 1, into each of which a transport fork 34 of an industrial truck 33 can engage. The receiving openings 3 each have at least one tensioning element 4, with which a releasable clamping fastening between the transport fork 34 and the base frame 1 can be produced.

Die Aufnahmeöffnungen 3 sind in ihrer Längserstreckung parallel zu einer ersten und zweiten Klemmvorrichtung 10, 20 ausgerichtet, die ausgebildet sind, eine Wickelwelle 31 aufzunehmen. Auf dem Grundrahmen 1 ist auf der Oberseite mindestens eine Klemmvorrichtung 10 angeordnet, mit der die Wickelwelle 31 aus der Materialrolle 30 herausgezogen und auf der Vorrichtung 100 befestigbar ist. Aufgrund der Länge der Wickelwelle 31, die bis zu 5 m betragen kann, ist eine entsprechende Längserstreckung der Klemmvorrichtung 10 notwendig, um das bei der Befestigung der Wickelwelle 31 auftretende Biegemoment durch das Eigengewicht der Wickelwelle 31 zu kompensieren. In diesem Ausführungsbeispiel sind zwei Klemmvorrichtungen 10, 20 mit Abstand zueinander auf dem Grundrahmen 1 angeordnet, die jeweils aus einem Grundkörper 11, 21 und einem Deckel 12, 22 bestehen, wobei Grundkörper 11, 21 und Deckel 12, 22 mittels Gelenk oder Scharnier 13, 23 aufklappbar verbunden sind. Die Deckel 12, 22 und der Grundkörper 11, 21 weisen jeweils eine halbe Zylinderbohrung 11a, 12a, 21a, 22a auf, die im verschlossenen Zustand, wenn die Wickelwelle 31 geklemmt wird, eine zylindrische Bohrung zur Aufnahme eines Schaftes der Wickelwelle 31 bilden. An der zu öffnenden Seite, gegenüberliegend vom Scharnier 13, 23 weist jede Klemmvorrichtung 10, 20 einen Flansch 15, 25 auf, der mit einer lösbaren Spannvorrichtung 14, 24 zusammenwirkt. Zumindest eine Klemmvorrichtung 10 weist im Bereich des Deckels 12 eine Öffnung 16 mit einem offenen Vorsprung 17 oder Nase auf. Die Öffnung 16 korrespondiert mit dem Ende der Wickelwelle 31, bzw. dem Schaftende der Wickelwelle 31. Der Vorsprung 17 ist ausgebildet, in eine umlaufende Nut 31a der Wickelwelle 31 formschlüssig einzugreifen, um diese das erste Stück aus der Materialrolle 30 heraus zu ziehen. Die Öffnung 16 und der Vorsprung 17 sind in Längserstreckung des Grundrahmens 1 an einer Außenkante angeordnet, um mit einem sehr kurzen Transportweg in die umlaufende Nut 31a der Wickelwelle 31 einzugreifen. In Längsachse auf der gegenüberliegenden Außenkante des Grundrahmens 1 ist ein Anschlag 5 angeordnet, der mit einer Stirnseite der Wickelwelle 31 zusammenwirken kann. In Figur 1 ist die Klemmvorrichtung 20 in geöffneter bzw. aufgeklappter Position dargestellt, und die Klemmvorrichtung 10 in geschlossener Position dargestellt.The longitudinal extension of the receiving openings 3 is aligned parallel to a first and second clamping device 10, 20, which are designed to receive a winding shaft 31. At least one clamping device 10 is arranged on the upper side of the base frame 1, with which the winding shaft 31 can be pulled out of the material roll 30 and fastened to the device 100. Due to the length of the winding shaft 31, which can be up to 5 m, a corresponding longitudinal extension of the clamping device 10 is necessary in order to compensate for the bending moment occurring when the winding shaft 31 is attached by the dead weight of the winding shaft 31. In this exemplary embodiment, two clamping devices 10, 20 are arranged at a distance from one another on the base frame 1, each of which consists of a base body 11, 21 and a cover 12, 22, the base body 11, 21 and cover 12, 22 by means of a joint or hinge 13, 23 are hingedly connected. The covers 12, 22 and the base body 11, 21 each have a half cylinder bore 11a, 12a, 21a, 22a which, in the closed state, when the winding shaft 31 is clamped, form a cylindrical bore for receiving a shaft of the winding shaft 31. On the side to be opened, opposite the hinge 13, 23, each clamping device 10, 20 has a flange 15, 25 which cooperates with a releasable clamping device 14, 24. At least one clamping device 10 has an opening 16 with an open projection 17 or nose in the area of the cover 12. The opening 16 corresponds to the end of the winding shaft 31 or the shaft end of the winding shaft 31. The projection 17 is designed to engage positively in a circumferential groove 31a of the winding shaft 31 in order to pull the first piece out of the roll 30 of material. The opening 16 and the projection 17 are arranged in the longitudinal extension of the base frame 1 on an outer edge in order to engage in the circumferential groove 31a of the winding shaft 31 with a very short transport path. In the longitudinal axis on the opposite outer edge of the base frame 1 is a Arranged stop 5, which can interact with an end face of the winding shaft 31. In Figure 1 the clamping device 20 is shown in the open or unfolded position, and the clamping device 10 is shown in the closed position.

Die Figuren 2 bis 4 zeigen die erste Klemmvorrichtung 10 in geschlossenem Zustand. Auf der gegenüberliegenden Seite der Vorrichtung 100 greift ein Flurförderfahrzeug 33 mit seinen Transportgabeln 34 in die Aufnahmeöffnungen 3 ein. Die Transportgabeln 34 sind klemmend durch die Spannelemente 4 mit dem Grundrahmen 1 bzw. mit den Aufnahmeöffnungen 3 verbunden. Das Flurförderfahrzeug 33 hebt die Vorrichtung 100 so an die Wickelwelle 31 an, dass der Vorsprung 17 der ersten Klemmvorrichtung 10 formschlüssig in eine umlaufende Nut 31a der Wickelwelle 31 eingreift. Aufgrund des Eigengewichtes der Materialrolle 30 und/oder eines nicht dargestellten Anschlages am Ablagetisch 32 bleibt diese auf dem Ablagetisch 32 liegen, wenn das Flurförderfahrzeug 33 anfängt, die Wickelwelle 31 aus der Materialrolle 30 herauszuziehen. Das Flurförderfahrzeug 33 zieht die Wickelwelle 31 jetzt um eine definierte Länge soweit aus der Materialrolle 30 heraus, der im Wesentlichen der Länge des Grundrahmens 1 entspricht. Die definierte Länge kann auf dem Boden vor dem Ablagetisch 32 markiert sein. Hilfreich kann auch eine Schienenanordnung vor dem Ablagetisch sein, so dass die Wickelwelle 31 beim Herausziehen nicht verkantet oder verbogen wird.The Figures 2 to 4 show the first clamping device 10 in the closed state. On the opposite side of the device 100, an industrial truck 33 engages with its transport forks 34 in the receiving openings 3. The transport forks 34 are connected in a clamping manner to the base frame 1 or to the receiving openings 3 by the clamping elements 4. The industrial truck 33 lifts the device 100 onto the winding shaft 31 in such a way that the projection 17 of the first clamping device 10 engages with a positive fit in a circumferential groove 31a of the winding shaft 31. Due to the dead weight of the roll of material 30 and / or a stop (not shown) on the support table 32, it remains on the support table 32 when the industrial truck 33 begins to pull the winding shaft 31 out of the roll of material 30. The industrial truck 33 now pulls the winding shaft 31 out of the roll of material 30 by a defined length which essentially corresponds to the length of the base frame 1. The defined length can be marked on the floor in front of the storage table 32. It can also be helpful to have a rail arrangement in front of the storage table so that the winding shaft 31 is not tilted or bent when it is pulled out.

Nach Figur 5 wird die Vorrichtung 100 von der Wickelwelle 31 gelöst und neu an der Wickelwelle 31 mit geöffneten Klemmvorrichtungen 10, 20 angesetzt. Die Deckel 12, 22 der Klemmvorrichtungen 10, 20 sind aufgeklappt und die Vorrichtung 100 soweit angehoben, dass die Wickelwelle 31 mit ihrer Unterseite jeweils in die halbe Zylinderbohrung 11a, 21a, des Grundkörpers 11, 21 eingreift. Nach Verschließen der Klemmvorrichtungen 10, 20 mittels der Deckel 12, 22 und Verspannen durch die Spannvorrichtungen 14, 24 ist die Wickelwelle 31 an der Vorrichtung 100 klemmend befestigt. Die Stirnseite der Wickelwelle 31 kann dabei an dem Anschlag 5 des Grundrahmens 1 anschlagen. Das Flurförderfahrzeug 33 kann die Wickelwelle 31 jetzt vollständig aus der Materialrolle 30 herausziehen. Aufgrund der Auflagefläche auf der Vorrichtung 100, durch die mit Abstand zueinander angeordneten Klemmvorrichtungen 10, 20 kann die Wickelwelle 31 zu einem Lager oder in den Speicher der Wickelmaschine transportiert werden, wodurch sich die Biegung der Wickelwelle 31 aufgrund des Eigengewichtes reduziert.To Figure 5 the device 100 is detached from the winding shaft 31 and reattached to the winding shaft 31 with the clamping devices 10, 20 open. The covers 12, 22 of the clamping devices 10, 20 are opened and the device 100 is raised to such an extent that the underside of the winding shaft 31 engages in half of the cylinder bore 11a, 21a of the base body 11, 21. After the clamping devices 10, 20 have been closed by means of the covers 12, 22 and braced The winding shaft 31 is clamped to the device 100 by means of the tensioning devices 14, 24. The end face of the winding shaft 31 can strike the stop 5 of the base frame 1. The industrial truck 33 can now pull the winding shaft 31 completely out of the roll 30 of material. Due to the contact surface on the device 100, through the spaced apart clamping devices 10, 20, the winding shaft 31 can be transported to a store or in the storage of the winding machine, whereby the bending of the winding shaft 31 due to its own weight is reduced.

Der Ablauf des Herausziehens der Wickelwelle 31 erfolgt in zwei Phasen:

  • Erste Phase:
    • Aufnahme der Vorrichtung 100 mit dem Flurförderfahrzeug 33, indem die Transportgabeln 33 in die Aufnahmeöffnungen 3 eingreifen
    • Klemmung der Transportgabeln 33 mit dem Grundrahmen 1 bzw. den Aufnahmeöffnungen 3 mittels Spannelement 4
    • Positionierung des Flurförderfahrzeuges 33 mit der Vorrichtung 100 vor der Wickelwelle 31, ggfs. geführt durch Leitschienen vor dem Ablagetisch 32
    • Höhenjustage der Vorrichtung 100 mittels Flurförderfahrzeug 33 zur Achse der Wickelwelle 31 und Positionierung des Wellenendes bzw. der Nut 31a in die Öffnung 16 bzw. mit dem Vorsprung 17
    • Ziehen der Wickelwelle 31 um eine vorgegebene Länge aus der Materialrolle 30, wobei die vorgegebene Länge am Boden oder durch Leitschienen markiert oder vorgegeben sein kann.
  • Zweite Phase:
    • Absenken der Vorrichtung 100 und Öffnen der Klemmvorrichtungen 10, 20
    • Positionieren der Wickelwelle 31 in die geöffnete Klemmvorrichtung 10, 20, verschließen der Klemmvorrichtung 10, 20 durch Verschwenken der Deckel 12, 22 und Sicherung durch die Spannvorrichtung 14, 24
    • Vollständiges Herausziehen der Wickelwelle 31 und Ablegen der Wickelwelle 31 in einem Speicher oder Lagerort.
The process of pulling out the winding shaft 31 takes place in two phases:
  • First phase:
    • The device 100 is picked up by the industrial truck 33 in that the transport forks 33 engage in the receiving openings 3
    • Clamping of the transport forks 33 to the base frame 1 or the receiving openings 3 by means of a clamping element 4
    • Positioning of the industrial truck 33 with the device 100 in front of the winding shaft 31, possibly guided by guide rails in front of the storage table 32
    • Height adjustment of the device 100 by means of an industrial truck 33 to the axis of the winding shaft 31 and positioning of the shaft end or the groove 31a in the opening 16 or with the projection 17
    • Pulling the winding shaft 31 by a predetermined length out of the roll of material 30, it being possible for the predetermined length to be marked or predetermined on the floor or by guide rails.
  • Second phase:
    • Lowering the device 100 and opening the clamping devices 10, 20
    • Positioning the winding shaft 31 in the opened clamping device 10, 20, closing the clamping device 10, 20 by pivoting the cover 12, 22 and securing it with the clamping device 14, 24
    • Complete pulling out of the winding shaft 31 and storage of the winding shaft 31 in a memory or storage location.

Die erfindungsgemäße Vorrichtung 100 hat den Vorteil, dass sie unabhängig von einer einzelnen Wickelmaschine verwendet werden kann. Sie ist nicht schienengeführt und kann mit jedem beliebigen Transportfahrzeug, dessen Transportgabeln 34 mit den Aufnahmeöffnungen 3 korrespondieren, verwendet werden. Ein weiterer Vorteil ist die kostengünstige Herstellung, da die Vorrichtung 100 kein eigenes Antriebs- oder Fahrsystem aufweist. Die Kombination mit einem schon vorhandenen Flurförderfahrzeug macht die Vorrichtung 100 sehr flexibel, preiswert und kompakt.The device 100 according to the invention has the advantage that it can be used independently of a single winding machine. It is not rail-guided and can be used with any transport vehicle whose transport forks 34 correspond to the receiving openings 3. Another advantage is the cost-effective production, since the device 100 does not have its own drive or driving system. The combination with an already existing industrial truck makes the device 100 very flexible, inexpensive and compact.
