Abstract
Description
Die Erfindung betrifft eine Wickelvorrichtung zum Umwickeln von Gegenständen, insbesondere Paletten, mit Folie.The invention relates to a winding device for wrapping objects, especially pallets, with foil.
Zum Transport von beispielsweise auf Paletten gestapelten Gegenständen, wie Kartons oder dgl., ist es bekannt, die Palette zusammen mit den Gegenständen mit einer Folie, insbesondere einer vorgestreckten Folie, zu umwickeln. Hierdurch sind die Gegenstände auf der Palette sicher gehalten. Das Umwickeln von Paletten erfolgt häufig von Hand. Da dies jedoch äußerst personal- und damit kostenintensiv ist, sind ferner Wickelvorrichtungen, d.h. automatisch arbeitende Wickelmaschinen, bekannt. Diese weisen einen Drehtisch auf, auf den die zu umwickelnde Palette gestellt wird. Zum Umwickeln der Palette wird der Drehtisch um eine vertikale Achse gedreht. Ferner ist die Folienrolle auf einem vertikal verschiebbaren Rollenhalter gehalten. Von der Folienrolle wird durch das Drehen der Palette die Folie abgezogen bzw. abgewickelt. Während dieses Abwickelvorgangs erfolgt ein vertikales Verschieben der Folienrolle, so dass die Palette, bzw. die auf der Palette gestapelten Gegenstände, über ihre gesamt Höhe mit Folie umwickelt werden.For transporting items stacked on pallets, such as Cardboard boxes or the like, it is known to put the pallet together with the items to wrap with a film, especially a pre-stretched film. As a result, the objects on the pallet are held securely. The wrapping of pallets is often done by hand. However, since this is extremely personnel and is therefore costly, winding devices are also automatically working winding machines, known. These have a turntable the pallet to be wrapped is placed. To wrap the pallet the turntable is rotated about a vertical axis. Furthermore, the film roll is on held a vertically movable roll holder. From the film roll the film is pulled or unwound by rotating the pallet. While this unwinding process is a vertical displacement of the film roll, so that the pallet, or the objects stacked on the pallet, over their total height to be wrapped with foil.
Üblicherweise werden die Gegenstände, wie beispielsweise Kartons, auf die Palette gestapelt und die Palette wird anschließend, beispielsweise mit Hilfe eines Hubwagens, zu der Wickelvorrichtung transportiert. Hier wird die Palette sodann auf den Drehtisch gestellt und der Hubwagen muss zum Umwickeln der Palette wieder entfernt werden. Nach dem automatischen Umwickeln der Palette durch die Wickelvorrichtung kann die umwickelte Palette mit Hilfe des Hubwagens wieder abtransportiert werden. Das automatische Umwickeln von Paletten mit Hilfe einer Wickelvorrichtung oder Wickelmaschine weist somit den Nachteil auf, dass die Palette mehrfach vom Hubwagen oder einer anderen geeigneten Transporteinrichtung aufgenommen werden muss.Usually, the items, such as cardboard boxes, are placed on the Pallet stacked and the pallet is then, for example with the help a pallet truck, transported to the winding device. Here is the palette then placed on the turntable and the pallet truck must be wrapped around the Pallet can be removed again. After the automatic wrapping of the pallet through the winding device, the wrapped pallet with the help of Pallet truck can be removed again. The automatic wrapping of Pallets with the help of a winding device or winding machine thus has the Disadvantage that the pallet multiple times from the pallet truck or another suitable transport equipment must be included.
Ferner ist aus JP 03111214 eine Wickelvorrichtung zum Umwickeln von auf einer Palette befindlichen Gegenständen bekannt. Diese Wickelvorrichtung weist einen L-förmigen Haltearm auf, der einen horizontal und einen vertikal angeordneten Arm aufweist. Mit dem horizontalen Arm ist ein Wickelarm drehbar verbunden. Mit dem Wickelarm ist wiederum ein Rollenhalter zur Aufnahme einer Folienrolle verbunden, wobei der Wickelarm zum Umwickeln der Gegenstände gedreht wird, so dass die Folienrolle um die Gegenstände herum geführt wird. Bei der in JP 03111214 beschriebenen Wickelvorrichtung ist der Haltearm mit einem Hubwagen verbunden. Hierdurch ist es möglich, mit Hilfe von kabelförmigen Auflageelementen des Hubwagens Paletten zu transportieren und diese, ohne sie beispielsweise auf eine Wickelvorrichtung mit Drehtisch absetzen zu müssen, zu umwickeln. Ein derartiger Hubwagen mit Wickelvorrichtung hat allerdings den Nachteil, dass insbesondere der Haltearm und der Wickelarm beim herkömmlichen Verwenden des Hubwagens, d.h. beim Transport von Paletten, die nicht umwickelt werden sollen, störend sind. Insbesondere ist es stets erforderlich, ein relativ großes Gewicht mitzuführen, wodurch das Handling des Hubwagens beeinträchtigt wird. Des Weiteren ist insbesondere der horizontale Teil des Haltearms störend, da hierdurch die Stapelhöhe von Gegenständen auf der Palette begrenzt ist. Der horizontale Teil des Haltearms ist beispielsweise auch beim Abstellen einer Palette in einem Regal oder einem anderen schwer zugänglichen Bereich störend. Furthermore, from JP 03111214 is a winding device for wrapping on a Pallet objects known. This winding device has one L-shaped arm, one horizontally and one vertically Arm. A wrapping arm is rotatably connected to the horizontal arm. With the winding arm is again a roll holder for receiving a film roll connected, the wrapping arm being rotated to wrap around the objects, so that the film roll is guided around the objects. In the JP 03111214 described winding device is the holding arm with a Pallet truck connected. This makes it possible to use cable-shaped Support elements of the pallet truck to transport pallets and these without them For example, to have to settle on a winding device with a turntable wrap. Such a pallet truck with a winding device has the Disadvantage that the holding arm and the wrap arm in particular conventional use of the truck, i.e. when transporting pallets, that are not supposed to be wrapped are annoying. In particular, it is always required to carry a relatively large weight, which makes the handling of the Pallet truck is affected. Furthermore, the horizontal one in particular Part of the holding arm is disruptive, as this increases the stacking height of objects the range is limited. The horizontal part of the holding arm is, for example also difficult when placing a pallet on a shelf or other accessible area annoying.

Hierbei ist es besonders bevorzugt, dass die Befestigungselemente derart ausgebildet sind, dass sie die Auflageelemente des Hubwagens zumindest teilweise umgreifen. Es ist somit möglich, die Auflageelemente, wie die Kabel des Hubwagens, in die Ausnehmungen einzuführen und auf diese einfache Weise die erfindungsgemäße Wickelvorrichtung mit dem Hubwagen zu verbinden. Durch ein einfaches Herausziehen der Auflageelemente aus den Ausnehmungen kann die Wickelvorrichtung von dem Hubwagen wieder getrennt werden. Eine aufwändige Montage ist somit nicht erforderlich. Vielmehr handelt es sich vorzugsweise bei den Befestigungselementen um eine durch Einstecken bzw. Herausziehen lösbare Verbindung.The fastening elements are preferably designed such that a quick and easy connection and disconnection of the winding device with or from the pallet truck is possible. It is particularly preferred here that the Fasteners have recesses into which the support elements of the Lift truck are insertable. It is particularly preferred here that the Fastening elements are designed such that they the support elements of the Reach around the truck at least partially. It is therefore possible to Support elements, such as the lift truck cables, into the recesses introduce and in this simple way the invention To connect the winding device to the pallet truck.

Bei derart ausgestalteten Befestigungselementen handelt es sich somit beispielsweise um eine hohl ausgebildete Gabel, in die die Auflageelemente bzw. die Gabel des Hubwagens eingesteckt werden können. Die Auflageelemente des Hubwagens sind hierbei von den Befestigungselementen vorzugsweise vollständig umschlossen. Die Befestigungselemente sind somit als hohle Hubwagengabel ausgeführt, wobei die einzelnen Befestigungselemente vorzugsweise über einen stabilisierenden Quersteg miteinander verbunden sind. Durch die als hohle Hubwagengabel ausgeführten Befestigungselemente ergibt sich für die Wickelvorrichtung eine Standfläche, die ausreicht, ohne zusätzliche Hilfsmittel einen stabilen Stand der Wickelvorrichtung beim Betrieb zu erreichen ohne das die Gefahr eines unbeabsichtigten Umkippens besteht. Diese Ausführungsform der Befestigungselemente hat ferner den Vorteil, dass die Lage der Wickelvorrichtung bezogen auf den Hubwagen auf einfache Weise, nämlich durch einfaches Einstecken der Auflageelemente in die Befestigungselemente definiert ist. Ferner handelt es sich bei dieser Ausführungsform um eine stabile Verbindung zwischen Wickelvorrichtung und Hubwagen, so dass auf die Wickelvorrichtung auch relativ große seitliche Kräfte wirken können.In a particularly preferred embodiment, the Fastening elements of the winding device essentially the shape of Support elements of the pallet truck. With such a design Fastening elements are thus, for example, hollow trained fork into which the support elements or the fork of the pallet truck can be inserted. The support elements of the lift truck are here preferably completely enclosed by the fasteners. The Fastening elements are thus designed as a hollow pallet truck fork the individual fasteners preferably via a stabilizing Crossbar are connected to each other. Through the hollow fork truck fork executed fasteners results for the winding device Stand area that is sufficient to provide a stable stand without additional aids Reaching device during operation without the risk of unintentional overturning exists. This embodiment of the Fasteners also have the advantage that the location of the Winding device based on the pallet truck in a simple manner, namely by simple insertion of the support elements defined in the fasteners is. Furthermore, this embodiment is a stable one Connection between winding device and pallet truck, so that on the Winding device can also act relatively large lateral forces.
Die erfindungsgemäße Wickelvorrichtung kann eine eigene Stromversorgung, beispielsweise in Form von aufladbaren Batterien, aufweisen. Um das Gewicht der Wickelvorrichtung zu reduzieren, weist die Wickelvorrichtung vorzugsweise einen Stromversorgungsanschluss auf, um die Wickelvorrichtung mit einer externen Stromquelle verbinden zu können. Besonders bevorzugt ist es hierbei, die Wickelvorrichtung mit der Stromversorgung eines Elektro-Hubwagens zu verbinden, da hierdurch eine große Mobilität gewährleistet ist und ein Umwickeln von Paletten unabhängig von stationären Stromanschlüssen erfolgen kann.The winding device according to the invention can have its own power supply, for example in the form of rechargeable batteries. About the weight to reduce the winding device, the winding device preferably has a power supply connection to the winding device with a to be able to connect an external power source. It is particularly preferred here the winding device with the power supply of an electric lift truck connect, as this ensures great mobility and a Pallets are wrapped independently of stationary power connections can.
Bei einer weiteren bevorzugten Ausführungsform der Erfindung sind Anschlagelemente vorgesehen, durch die die Lage der zu umwickelnden Gegenstände, insbesondere der Palette, definiert wird. Hierdurch ist gewährleistet, dass der Rollenhalter beim Umwickeln der Palette frei um die Palette herumgeführt werden kann. Derartige Anschlagelemente sind vorzugsweise an den Befestigungselementen vorgesehen. Dies ist insbesondere vorteilhaft, wenn die Befestigungselemente zumindest teilweise die Form der Auflageelemente des Hubwagens aufweisen, insbesondere als Einstecktaschen ausgebildet sind. Vorzugsweise handelt es sich bei dem Anschlagelement um ein keilförmiges Anschlagelement, das auf der Oberseite, d.h. der Auflagefläche der Befestigungselemente vorgesehen ist.In a further preferred embodiment of the invention Stop elements are provided through which the position of the to be wrapped Objects, especially the pallet, is defined.

Bei dem Vorsehen eines Anschlagelements handelt es sich um eine eigenständige Erfindung, wobei das Anschlagelement beispielsweise nicht nur an der vorstehend beschriebenen Wickelvorrichtung, sondern auch an einer fest mit einem Hubwagen verbundenen Wickelvorrichtung, insbesondere an den Auflageelementen, vorgesehen sein kann. Die Erfindung betrifft also auch ein Palettenanschlagelement zur Aufnahme einer Palette, wobei das Palettenanschlagelement insbesondere für die wie vorstehend beschriebene Wickelvorrichtung oder einen Hubwagen geeignet ist. Erfindungsgemäß weist das Auflageelement an seiner Oberseite das Palettenanschlagelement zur Lagedefinition der Palette auf. Das Anschlagelement, d. h. das Palettenanschlagelement, weist eine gegen die horizontale geneigte und zur aufzunehmenden Palette hin abfallende Reibfläche zum reibschlüssigen Halten der Palette auf. Das Anschlagelement ist beispielsweise zumindest teilweise keilförmig ausgestaltet, so dass die Reibfläche durch die Seitenfläche des keilförmigen Teils des Anschlagelements gebildet wird. Bei der Aufnahme der Palette durch das erfindungsgemäße Palettenanschlagelement erfolgt durch den keilförmigen Bereich des Anschlagelements ein leichtes Anheben der Palette, wodurch allmählich ein Großteil des Gewichts der Palette und der auf der Palette gelagerten Waren von der Reibfläche aufgenommen wird. Dadurch entsteht eine hohe Reibkraft, welche die Palette in Ihrer Lage definiert. Im Gegensatz zu einem beispielsweise rechtwinklig ausgeführten Anschlagelement wird ein plötzliches Anstoßen der Palette mit dem Anschlagelement vermieden, so dass die Gefahr, die Palette und/ oder die Ware zu beschädigen reduziert ist. Ferner ist ein Zurückprallen der Palette von dem Anschlagelement und eine damit verbundene Lageveränderung vermieden, so dass auch bei unvorsichtigem Gebrauch der Wickelvorrichtung bzw. des Hubwagens, mit dem das erfindungsgemäße Palettenanschlagelement verbunden ist, eine definierte Lage der Palette relativ zu dem Auflageelement gewährleistet ist.The provision of a stop element is a independent invention, the stop element, for example, not only on the winding device described above, but also with a fixed a winding device connected to a lifting device, in particular to the Support elements can be provided.

H. the Pallet stop element, has one inclined towards the horizontal and towards Pallet to be picked up sloping friction surface for frictional holding the pallet. The stop element is, for example, at least partially wedge-shaped, so that the friction surface through the side surface of the wedge-shaped part of the stop element is formed. When recording the Pallet through the pallet stop element according to the invention takes place through the wedge-shaped area of the stop element a slight lifting of the pallet, gradually reducing much of the weight of the pallet and that on the pallet stored goods is absorbed by the friction surface. This creates one high friction, which defines the pallet in your position. In contrast to a stop element, for example at right angles, is a Avoid sudden impact of the pallet with the stop element, so that the risk of damaging the pallet and / or the goods is reduced. Further is a rebound of the pallet from the stop element and one with it associated change in position avoided, so that even with careless Use of the winding device or the lift truck with which the Pallet stop element according to the invention is connected, a defined position the pallet is guaranteed relative to the support element.

Die erfindungsgemäße Wickelvorrichtung weist einen Basiskörper 10 auf, der mit
zwei Auflageelementen 12 verbunden ist, wobei die Auflageelemente 12 wie bei
einem Gabelstapler parallel und gabelförmig ausgebildet sind. Mit dem
Basiskörper 10 ist ein L-förmiger Haltearm 14 verbunden. Der Haltearm 14 weist
einen vertikal angeordneten säulenartigen Teil 16 und einen vertikal
angeordneten Arm 18 auf. Mit dem Arm 18 ist ein Wickelarm 20 verbunden, der
in Richtung eines Pfeils 22 drehbar mit dem Arm 18 verbunden ist. Mit dem
Wickelarm 20 ist sodann ein vertikal verlaufender Rollenhalter 24 starr
verbunden. Der Rollenhalter 24 trägt eine Folienrolle 26.The winding device according to the invention has a
Zum Umwickeln von auf einer Palette 28 angeordneten Gegenständen 30 wird
der Wickelarm 20 zusammen mit dem Rollenhalter 24 in Richtung des Pfeils 22
um die aufeinander gestapelten Gegenstände herum geschwenkt. Hierbei wird
die Folienbahn 32 um die Gegenstände 30 herum gewickelt, um diese zu
fixieren. Hierzu ist die Folienrolle 26 am Rollenhalter 24 in Richtung des Pfeils 34
bewegbar. Die erforderlichen Steuerelemente zur Steuerung des
Umwickelvorgangs sind beispielsweise in dem Basiskörper 10 angeordnet.For wrapping objects 30 arranged on a
Erfindungsgemäß sind die Auflageelemente 12 als Befestigungselemente
ausgestattet. Hierzu weisen die Auflageelemente 12 jeweils eine Ausnehmung 36
auf, so dass im dargestellten Ausführungsbeispiel die Auflageelemente 12 hohl
ausgebildet sind. Die Auflageelemente 12, deren Form im Wesentlichen der Form
von Auflageelementen 38 eines Hubwagens entsprechen, sind vorzugsweise hohl
ausgebildet, so dass die Auflageelemente bzw. Gabeln 38 eines Hubwagens 40
in die als Befestigungselemente dienenden Auflageelemente 12 der
erfindungsgemäßen Wickelvorrichtung eingeschoben werden können. Hierdurch
ist ein sicheres Verbinden zwischen der Wickelvorrichtung und dem Hubwagen
40 möglich. Die Wickelvorrichtung kann hierdurch mobil eingesetzt werden. Es
ist somit möglich, mit Hilfe des Hubwagens 40 in Kombination mit der
erfindungsgemäßen Wickelvorrichtung eine mit Gegenständen 30 versehene
Palette 28 sowohl zu transportieren als auch zu umwickeln.According to the invention, the
Vorzugsweise handelt es sich bei dem Hubwagen 40 um einen Elektro-Hubwagen.
Dies hat den Vorteil, dass die erfindungsgemäße Wickelvorrichtung
keine eigene Stromversorgung aufweisen muss, sondern über einen
Stromversorgungsanschluss 42 mit den Batterien des Elektro-Hubwagens
verbunden werden kann.The lifting
Um zu vermeiden, dass die Auflageelemente 12 zu weit unter die Palette 28
geschoben werden und sodann ein freies Drehen des Wickelarms 20 zusammen
mit dem Rollenhalter 28 nicht mehr möglich wäre, sind Anschlagelemente 44
(Fig. 5) vorgesehen. Die Anschlagelemente 44 sind keilförmig ausgebildet und
jeweils mit einem der beiden Auflageelemente 12 verbunden. Die
Anschlagelemente 44 sind an einer Oberseite 46 der Auflageelemente 12
angeordnet. In dem keilförmigen Bereich der Anschlagelemente 44 ist eine
Reibfläche 48 ausgebildet, die gegen die Horizontale geneigt ist und zur Palette
28 hin abfällt. Mit Hilfe der Reibflächen 48 erfolgt eine reibschlüssige Verbindung
der Anschlagelemente 44 und somit der Wickelvorrichtung mit der Palette 28 in
definierter Lage.In order to avoid that the
