Description

Die Erfindung betrifft eine Bereitstellungsvorrichtung für Folienrollenkerne sowie ein Verfahren zum Bereitstellen von Folienrollenkernen.The invention relates to a supply device for film roll cores and to a method for providing film roll cores.

Folienrollen werden üblicherweise mit Hilfe von Wickelmaschinen hergestellt, indem eine Folienbahn von einer ersten Folienrolle abgewickelt und auf einen Folienrollenkern aufgewickelt wird. Hierbei ist die auf der ersten Rolle aufgewickelte Folienbahn üblicherweise um ein Vielfaches länger als die auf den Kern aufgewickelte Folienbahn. Die hergestellte Folienrolle mit geringerem Durchmesser kann sodann beispielsweise von Hand in geeigneten Handhabungsgeräten zum Umwickeln von Paletten o.dgl. verwendet werden. Ferner ist es möglich, dass mit Hilfe der Wickelmaschine eine gereckte, d.h. vorgedehnte, Folienbahn hergestellt wird. Neben einem Verwenden der hergestellten Folienrollen in von Hand betätigten Abrolleinrichtungen o.dgl. werden derartige Folienrollen auch in automatischen Palettenumwickelvorrichtungen u.dgl. verwendet. Eine Vorrichtung zum Herstellen von Folienrollen mit einer vorgereckten Folienbahn ist beispielsweise in WO 95/13965 beschrieben.Film rolls are usually produced by means of winding machines by unwinding a film web from a first film roll and winding it onto a film roll core. Here, the wound up on the first roll of film is usually many times longer than the wound on the core film web. The produced film roll with a smaller diameter can then, for example, by hand in suitable handling equipment for wrapping pallets or the like. be used. Furthermore, it is possible that by means of the winding machine a stretched, i. pre-stretched, film web is produced. In addition to using the film rolls produced in manually operated unwinding devices or the like. Such film rolls are also in automatic Pallettenumwickelvorrichtungen and the like. used. An apparatus for producing film rolls with a pre-stretched film web is described for example in WO 95/13965.

Weitere Vorrichtungen und Verfahren, die als nächster Stand der Technik anzusehen sind, sind in DE 197 52 112 C und EP 0 896 940 A offenbart.Other devices and methods to be considered as the closest prior art are disclosed in DE 197 52 112 C and EP 0 896 940 A.

Bei den Folienrollenkernen handelt es sich beispielsweise um hohle rohrförmige Pappkerne. In bestehende Folienrollen-Wickelmaschinen müssen die Folienrollenkerne von Hand eingesetzt und die fertig gewickelten Folienrollen wieder von Hand aus der Wickelmaschine entnommen werden.The film roll cores are, for example, hollow tubular cardboard cores. In existing film roll winding machines, the film roll cores must be inserted by hand and the finished wound film rolls must again be removed manually from the winding machine.

Aufgabe der Erfindung ist es, den Herstellungsprozess von Folienrollen weiter zu automatisieren.The object of the invention is to further automate the manufacturing process of film rolls.

Die Lösung der Aufgabe erfolgt erfindungsgemäß durch eine Bereitstellungsvorrichtung gemäß Anspruch 1 sowie ein Verfahren gemäß Anspruch 10.The object is achieved by a provisioning device according to claim 1 and a method according to claim 10.

Die erfindungsgemäße Bereitstellungsvorrichtung für Folienrollenkerne für eine Folienrollen-Wickelmaschine weist eine Zuführvorrichtung auf, mit der die Folienrollenkerne in horizontaler Lage zugeführt werden. An die Zuführvorrichtung ist eine Aufrichtvorrichtung angeschlossen, durch die die horizontal ausgerichteten Folienrollenkerne aus ihrer horizontalen Lage in eine vertikale Lage übergeführt werden. In der vertikalen Lage werden die Folienrollenkerne sodann mit Hilfe einer Übergabevorrichtung aufgenommen und an die Folienrollen-Wickelmaschine übergeben. Der Folienrollenkern ist sodann in der Wickelmaschine vertikal angeordnet, so dass das Wickeln der Folienrolle in vertikaler Ausrichtung der Folienrollen erfolgt. Bei derartigen Vertikal-Wickelmaschinen müssen die Folienrollenkerne in vertikaler Lage zugeführt werden. Da eine unmittelbare vertikale Zuführung der Folienrollenkerne technisch aufwändig und schwierig ist, erfolgt erfindungsgemäß das Zuführen der Folienrollenkerne über eine Zuführvorrichtung in horizontaler Lage, wobei die Folienrollenkerne anschließend mit Hilfe der Aufrichtvorrichtung in die vertikale Lage übergeführt werden.The inventive supply device for film roll cores for a film roll winding machine has a feed device with which the film roll cores are fed in a horizontal position. To the feeder a Aufrichtvorrichtung is connected, are converted by the horizontally oriented film roll cores from its horizontal position into a vertical position. In the vertical position, the film roll cores are then picked up by means of a transfer device and transferred to the film roll winding machine. The film roll core is then arranged vertically in the winding machine, so that the winding of the film roll takes place in a vertical orientation of the film rolls. In such vertical winding machines, the film roll cores must be supplied in a vertical position. Since an immediate vertical feed of the film roll cores is technically complicated and difficult, according to the invention the feeding of the film roll cores takes place via a feed device in a horizontal position, wherein the film roll cores are then transferred into the vertical position with the aid of the erecting device.

Mit Hilfe der erfindungsgemäßen Bereitstellungsvorrichtung ist es somit möglich, Folienrollenkerne automatisch einer Folienrollen-Wickelmaschine zuzuführen. Hierdurch sind die Produktionskosten für Folienrollen erheblich reduziert.With the aid of the provisioning device according to the invention, it is thus possible to automatically supply film roll cores to a film roll winding machine. As a result, the production costs for film rolls are significantly reduced.

Bei der Übergabevorrichtung kann es sich beispielsweise um einen Greifarm o.dgl. handeln, von dem der Folienkern durch eine Greifzange o.dgl. aufgenommen wird und sodann aus einer Aufnahmeposition in eine Übergabeposition verfahren wird, an der der Folienrollenkern sodann beispielsweise in einer Halterung der Wickelmaschine übergeben wird. Die Aufrichtvorrichtung kann in die beispielsweise als Greifarm ausgebildete Übergabevorrichtung integriert sein. Hierzu ist der Greifarm beispielsweise derart ausgebildet, dass die Greifzange mit nach unten weisender Öffnung über den horizontal liegenden Folienrollenkern geführt wird und diesen greifen kann. Anschließend wird die Zange bzw. der Greifarm um 90° geschwenkt, so dass der Folienrollenkern im Wesentlichen vertikal ausgerichtet ist, wobei der Folienrollenkern vor, nach oder während dem Schwenken um 90° in die Übergabeposition verfahren wird.The transfer device may, for example, a gripping arm or the like. act, of which the film core by gripping tongs or the like. is taken and then moved from a receiving position into a transfer position, where the film roll core is then transferred, for example, in a holder of the winding machine. The erecting device can be integrated into the transfer device designed, for example, as a gripping arm. For this purpose, the gripping arm is for example designed such that the gripping pliers is guided with downwardly facing opening on the horizontally lying film roll core and can grab this. Subsequently, the forceps or the gripping arm is pivoted by 90 °, so that the film roll core is oriented substantially vertically, wherein the film roll core is moved before, after or during pivoting by 90 ° in the transfer position.

Bei einer bevorzugten Ausführungsform weist die Aufrichtvorrichtung eine Aufnahmeeinrichtung auf, die zur Aufnahme eines einzelnen Folienrollenkerns dient. Bei der Aufnahmeeinrichtung handelt es sich um eine Senke oder Wanne, deren Querschnitt vorzugsweise im Wesentlichen den Außenabmessungen des Folienkerns entspricht. Da in der Aufnahmeeinrichtung somit nur ein einzelner Folienrollenkern aufgenommen werden kann, kann aus der Aufnahmeeinrichtung auf einfache Weise, beispielsweise mit dem Greifarm, der Folienrollenkern entnommen werden. Vorzugsweise ist die Aufnahmeeinrichtung mit einer Schwenkeinrichtung zum Aufrichten der Folienkerne verbunden. Der einzelne in der Aufnahmeeinrichtung liegende Folienrollenkern wird somit durch Schwenken der Aufnahmeeinrichtung um 90° in die vertikale Lage gebracht. In der vertikalen Lage kann der Folienrollenkern sodann von der Übergabevorrichtung, wie beispielsweise einem Greifarm, aufgenommen und in die Übergabeposition verfahren werden.In a preferred embodiment, the erecting device has a receiving device which serves to receive a single film roll core. The receiving device is a depression or trough whose cross section preferably corresponds substantially to the outer dimensions of the foil core. Since only a single film roll core can thus be received in the receiving device, the film roll core can be removed from the receiving device in a simple manner, for example with the gripping arm. Preferably, the receiving device is connected to a pivoting device for erecting the foil cores. The individual lying in the receiving device film roll core is thus brought by pivoting the receiving device by 90 ° in the vertical position. In the vertical position of the film roll core can then be picked up by the transfer device, such as a gripper arm, and moved into the transfer position.

Die Zuführvorrichtung ist vorzugsweise mit einer Vereinzelungseinrichtung zur Vereinzelung der Folienrollenkerne verbunden. Bei der Vereinzelungseinrichtung kann es sich beispielsweise um einen Schieber handeln, der zwischen zwei hintereinander angeordnete Folienrollenkerne geschoben wird, so dass stets nur einer der beiden Folienrollenkerne entnommen werden kann. Ebenso kann ein Schieber vorgesehen sein, der seitlich in die rohrförmig ausgebildeten Folienrollenkerne eingreift und somit immer nur einen Folienrollenkern freigibt, der sodann vorzugsweise in die Aufnahmeeinrichtung, beispielsweise durch Rollen über eine schiefe Ebene, transportiert wird, so dass in der Aufnahmeeinrichtung stets nur ein einziger Folienrollenkern angeordnet ist.The feeding device is preferably connected to a separating device for separating the film roll cores. The separating device can be, for example, a slide which is pushed between two film roll cores arranged one behind the other so that only ever one of the two film roll cores can be removed. Likewise, a slider may be provided which engages laterally in the tubular film roll cores and thus always releases only a film roll core, which is then preferably transported into the receiving device, for example by rolling over an inclined plane, so that in the receiving device always only a single Foil roller core is arranged.

Die Erfindung betrifft ferner ein Verfahren zum Bereitstellen von Folienrollenkernen für eine Wickelmaschine, insbesondere Vertikal-Wickelmaschine. Erfindungsgemäß werden die Folienrollenkerne in horizontaler Lage bereitgestellt. Im nächsten Schritt wird ein Folienrollenkern aus der horizontalen Lage aufgerichtet und somit in eine vertikale Lage überführt. In dieser vertikalen Lage erfolgt ein Übergeben des Folienrollenkerns an die Wickelmaschine. Da sowohl das Aufrichten des Folienrollenkerns sowie das Übergeben des Folienrollenkerns automatisch erfolgt, ist mit Hilfe dieses Verfahrens der Automatisierungsgrad zur Herstellung von Folienrollen erhöht.The invention further relates to a method for providing film roll cores for a winding machine, in particular vertical winding machine. According to the invention, the film roll cores are provided in a horizontal position. In the next step, a film roll core is erected from the horizontal position and thus transferred to a vertical position. In this vertical position, the film roll core is transferred to the winding machine. Since both the erection of the film roll core and the transfer of the film roll core takes place automatically, the degree of automation for the production of film rolls is increased with the aid of this process.

Das Bereitstellen der Folienrollenkerne erfolgt vorzugsweise über eine Zuführvorrichtung, in der eine Vielzahl von Folienrollenkernen enthalten sind. Vorzugsweise werden die Folienrollenkerne über eine Vereinzelungseinrichtung automatisch vereinzelt, so dass die einzelnen Folienrollenkerne auf einfache Weise aufgerichtet werden können.The provision of the film roll cores preferably takes place via a feed device in which a multiplicity of film roll cores are contained. Preferably, the film roll cores are automatically separated by a separating device, so that the individual film roll cores can be erected in a simple manner.

Besonders bevorzugt ist die Verwendung der erfindungsgemäßen Bereitstellungsvorrichtung zur Durchführung des erfindungsgemäßen Verfahrens.Particularly preferred is the use of the delivery device according to the invention for carrying out the method according to the invention.

In einer Zuführvorrichtung 10 sind in einem in Form einer Schütte o.dgl. ausgebildeten Bereich eine Vielzahl von Folienrollenkernen 12 angeordnet, wobei die Kerne 12 zueinander parallel in der Zuführvorrichtung 10 liegen. Hierbei sind die Folienrollenkerne 12 horizontal angeordnet. Der als Schütte 14 ausgebildete Bereich der Zuführvorrichtung 10 ist mit einem Zuführkanal 16 verbunden. Die Abmessungen des Zuführkanals 16 sind hierbei derart gewählt, dass die Breite des Zuführkanals geringfügig breiter als der Durchmesser eines Folienrollenkerns 12 ist. Die Folienrollenkerne 12 sind somit im Zuführkanal in Transportrichtung, d.h. in Fig. 2 nach unten, hintereinander angeordnet. Um ein Nachrutschen der Folienrollenkerne zu gewährleisten, weist die Schütte bzw. der trichterförmige Bereich 14 eine geneigte Unterseite auf, die in dem dargestellten Ausführungsbeispiel in den vertikal ausgerichteten Zuführkanal 16 mündet.In a feeder 10 or the like in a form of a chute. formed region a plurality of film roll cores 12, wherein the cores 12 are parallel to each other in the feeder 10. Here, the film roll cores 12 are arranged horizontally. The trained as a chute 14 area of the feeder 10 is connected to a feed channel 16. The dimensions of the feed channel 16 are in this case selected such that the width of the feed channel is slightly wider than the diameter of a film roll core 12. The film roll cores 12 are thus in the feed channel in the transport direction, i. in Fig. 2 down, arranged one behind the other. In order to ensure slipping of the film roll cores, the chute or the funnel-shaped region 14 has an inclined underside, which opens into the vertically oriented feed channel 16 in the illustrated embodiment.

Die Zuführvorrichtung 10 weist am Ende des Zuführkanals 16 eine Vereinzelungseinrichtung 18 auf. Die Vereinzelungseinrichtung 18 weist einen mit einem Stellglied 20 verbundenen Schieber 22 auf. Der Schieber 22 dient einerseits dazu, eine als Klappe 24 ausgebildete Rückhalteeinrichtung durch Schwenken um eine Achse 26 zu öffnen, so dass der in dem Zuführkanal 16 unterste Folienrollenkern 12 über eine schiefe Ebene 28 in Richtung einer Aufrichtvorrichtung 32 rollt. Zusätzlich dient der Schieber 22 dazu, den nachfolgenden Folienrollenkern 12 in dem Zuführkanal 16 zurück zu halten.The feeding device 10 has a separating device 18 at the end of the feed channel 16. The singulator 18 has a slider 22 connected to an actuator 20. On the one hand, the slide 22 serves to open a retainer designed as a flap 24 by pivoting about an axis 26, so that the film roll core 12 which is the lowest in the feed channel 16 rolls over an inclined plane 28 in the direction of a erecting device 32. In addition, the slider 22 serves to retain the subsequent film roll core 12 in the feed channel 16.

Durch Zurückziehen des Schiebers 22 in Richtung eines Pfeils 32, d.h. in Fig. 2 nach links, wird die Klappe 24 wieder geschlossen und der durch den Schieber 22 zurückgehaltene Folienrollenkern 12 rutscht nach unten an die Stelle des von der Klappe 24 zurückgehaltenen Folienrollenkerns 12.
