Abstract

An apparatus for wrapping an object having vertical sides and a top with a hood-shaped foil having a closed end and an open end fits the foil over the object in such a manner that excess-foil projections are formed at the closed end that project outward from the top of the object and an empty space is formed adjacent each projection between the foil and the object. The excess-foil projections are mechanically engaged and physically tucked between the object and the foil to push the projections into the respective empty spaces.

Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Einbringen von Folienüberständen eines einen Gutstapel seitlich und wenigstens teilweise oberseitig umhüllenden und in diesen Bereichen an dem Gutstapel anliegenden Folienabschnittes.The invention relates to a device and a method for introducing film overhangs of a stack laterally and at least partially enveloping the upper side and in these areas adjacent to the stack of goods film section.

Zum Umhüllen eines Gutstapels mit einem Folienabschnitt, werden üblicherweise aus einem Flachschlauch bestehende Schrumpf- oder Stretchhauben verwendet. Es sind aber auch andere Schlauchtypen denkbar. Im Bereich der Oberseite des Gutstapels sind zumindest die beiden Randbereiche zugeschweißt, sofern ein Ende des Folienabschnittes nicht sogar vollständig zugeschweißt ist. Im umhüllten Zustand bilden sich dabei üblicherweise in dem Bereich von zwei gegenüberliegenden Seitenkanten mit der kürzeren Länge des Gutstapels im Wesentlichen dreiecksförmig ausgebildete Folienüberstände. Diese gehen in etwa von den Ecken des Gutstapels aus und stehen über die Seitenkanten des Gutstapels über.For wrapping a stack of goods with a film section, are usually made of a flat hose Shrink or stretch hoods used. But they are too other types of hose conceivable. In the area of the top of Pile of goods, at least the two edge areas are welded shut, provided one end of the film section is not even completely welded. In the wrapped state usually form in the range of two opposite side edges with the shorter length of Gutstapels essentially triangular shaped Foil projections. These go from about the corners of the Pile of goods and stand over the side edges of the Good pile over.

Diese Folienüberstände, auch Zipfel oder Kapuzen genannt, müssen entweder an den Seiten oder an der Oberseite des Gutstapels fixiert werden, damit der umhüllte Gutstapel eine optisch ansprechende Umhüllung erhält. Als Nachteil erweist sich, dass die fixierten Folienüberstände sich z. B. beim Transport des Gutstapels selbstständig oder auch infolge eines Hängenbleibens an Vorsprüngen eines Transportmittels lösen können. Sofern eine Fixierung nur bereichsweise vorgenommen worden ist, kann dabei zudem noch der Folienabschnitt beschädigt werden, wodurch eine hinreichende Sicherung des Gutstapels unter Umständen nicht immer gewährleistet ist.These film overhangs, also called Zipfel or hoods, must be either on the sides or at the top of the Gutstapels be fixed so that the wrapped stack receives a visually appealing enclosure. As a disadvantage proves that the fixed film overhangs themselves z. B. independently or when transporting the stack also due to sticking to projections of a Can solve transport. Unless a fixation only In some areas, it can also still the film section will be damaged, creating a sufficient assurance of the good pile under circumstances not always guaranteed.

Weiterhin ist aus der DE-A-1 586 456 ein Verfahren zum Einbringen von Folienüberständen gemäss den Oberbegriffen der Ansprüche 12 und 13 bekannt.Furthermore, from DE-A-1 586 456 a method for introducing foil supernatants according to the preambles of claims 12 and 13 is known.

Aufgabe der Erfindung ist es daher, eine Vorrichtung anzugeben, mittels derer die vorgenannten Nachteile bei einem mittels eines Folienabschnittes umhüllten Gutstapels vermieden werden.The object of the invention is therefore to provide a device by means of which the aforementioned disadvantages in a avoided by means of a foil section wrapped stack become.

Diese Aufgabe wird gelöst durch eine Vorrichtung zum Einbringen von Folienüberständen eines einen Gutstapel seitlich und wenigstens teilweise oberseitig umhüllenden und in diesen Bereichen an dem Gutstapel anliegenden Folienabschnittes, insbesondere einer Folienhaube, wobei die Folienüberstände insbesondere dreiecksförmig ausgebildet und im Bereich zweier gegenüberliegender Kanten der Oberseite des Gutstapels angeordnet sowie in etwa von den Ecken des Gutstapels ausgehend sind, mit wenigstens einer die Folienüberstände in den Bereich zwischen dem Gutstapel und dem Folienabschnitt einbringenden Verlagerungseinrichtung.This object is achieved by a device for introducing of film projections of a stack of goods laterally and at least partially enveloping the upper side and in these areas adjacent to the stack of goods film section, in particular a film hood, wherein the film projections in particular triangular shaped and in the region of two opposite edges of the top the pile of goods arranged as well as from about the corners of Gutstapels are starting, with at least one of the film projections in the area between the stack and the Film section introducing displacement device.

Durch das Einbringen der Folienüberstände in den Bereich zwischen dem Gutstapel und dem Folienabschnitt mittels der Verlagerungseinrichtung erhält der Gutstapel zum einen auch im Bereich der Folienüberstände eine glatte und optisch ansprechende Oberfläche. Zum anderen können die Folienüberstände sich nicht mehr lösen, da sie von dem Folienabschnitt überdeckt werden. Sofern es sich bei dem Folienabschnitt um eine Schrumpfhaube handelt, wird vorzugsweise der Gutstapel zunächst umhüllt und dann die Folienüberstände mittels der Verlagerungseinrichtung in den Bereich zwischen dem Gutstapel und dem Folienabschnitt eingebracht. Dann wird der Folienabschnitt geschrumpft. Es ist aber auch möglich, dass das Einbringen nach dem Schrumpfen durchgeführt wird. Bei Verwendung einer Stretchfolie werden eventuell noch auftretende Folienüberstände nach dem Stretchen mittels der Verlagerungseinrichtung in den Bereich zwischen dem Gutstapel und dem Folienabschnitt eingebracht.By introducing the film projections in the area between the stack and the film section by means of Displacement device receives the stack for a also in the area of the film projections a smooth and optical attractive surface. On the other hand, the film projections will not come off anymore, as they are from the foil section be covered. If it is the film section is a shrink hood, is preferably the stack initially wrapped and then the film projections by means of the displacement device in the area introduced between the stack and the film section. Then the film section is shrunk. It But it is also possible that the introduction to the Shrinking is performed. When using a Stretch film will eventually appear film overhangs after stretching by means of the displacement device in the area between the stack and the Film section introduced.

Bei einer Ausführung der Vorrichtung kann zum Einbringen der Folienüberstände in den Bereich zwischen den Seiten des Gutstapels und dem Folienabschnitt wenigstens eine Verlagerungseinrichtung im Wesentlichen vertikal ausgerichtet sein.In one embodiment of the device can be used for insertion the film projections in the area between the sides the stack of goods and the film section at least one Displacement device substantially vertically aligned be.

Bei einer anderen Ausführungsform kann zum Einbringen der Folienüberstände in den Bereich zwischen der Oberseite des Gutstapels und dem Folienabschnitt wenigstens eine Verlagerungseinrichtung im Wesentlichen horizontal ausgerichtet sein. Eine solche Ausführungsform einer erfindungsgemäßen Vorrichtung bietet sich an, wenn der umhüllte Gutstapel auch zur Außenlagerung geeignet sein soll. Da die Folienüberstände in den Bereich zwischen der Oberseite des Gutstapels und dem Folienabschnitt eingebracht werden, kann beispielsweise kein Regenwasser eintreten.In another embodiment, for introducing the Film projections in the area between the top of the Good stack and the film section at least one displacement device oriented substantially horizontally be. Such an embodiment of an inventive Device lends itself to when the wrapped stack should also be suitable for outdoor storage. Because the film overhangs in the area between the top of the pile of goods and the film section can be introduced For example, no rainwater enter.

Wenigstens eine Verlagerungseinrichtung kann eine luftstromerzeugende Einblaseinrichtung zum berührungslosen Einbringen aufweisen. Im einfachsten Fall ist dies eine Düse, mittels derer Luft auf die Folienüberstände geblasen wird, so dass diese in den Bereich zwischen dem Gutstapel und dem Folienabschnitt eingedrückt bzw. eingebracht werden.At least one displacement device can be a Air-flow generating blowing device for non-contact Have introduced. In the simplest case this is one Nozzle, by means of which air is blown onto the film overhangs so that these are in the area between the pile of goods and the foil section pressed or introduced become.

Bei einer bevorzugten Ausführungsform einer erfingungsgemäßen Vorrichtung weist wenigstens eine Verlagerungseinrichtung ein verlagerbares Einschiebelement zum mechanischen Einbringen auf. Zum Einbringen eines Folienüberstandes wird das Einschiebelement mit dem Folienüberstand in Kontakt gebracht, so dass der Folienüberstand durch das Einschiebelement entweder in den Bereich zwischen einer Seite des Gutstapels und dem Folienabschnitt oder in den Bereich zwischen der Oberseite des Gutstapels und dem Folienabschnitt eingeschoben wird.In a preferred embodiment of a erfingungsgemäßen Device has at least one displacement device a movable insertion element for mechanical Bring in. For introducing a film overhang the push-in element with the film projection in Brought the contact so that the film projection through the Sliding element either in the area between a Side of the stack and the foil section or in the Area between the top of the stack and the film section is inserted.

Vorzugsweise entspricht das Einschiebelement in etwa der Form eines überstehenden Folienüberstandes. Hierdurch wird erreicht, dass der Folienüberstand vollständig in den Bereich zwischen dem Folienabschnitt und dem Gutstapel eingebracht wird.Preferably, the insertion element corresponds approximately to the Shape of a protruding film supernatant. This will achieved that the film projection completely in the area introduced between the film section and the stack becomes.

Dabei kann wenigstens ein Einschiebelement, vorzugsweise über einen Arm, mit einer Verfahreinrichtung, vorzugsweise mit einem verfahrbaren Schlitten, verbunden sein, so dass das Einschiebelement in die gewünschte Richtung und Position verfahrbar ist.In this case, at least one insertion element, preferably over an arm, with a traversing device, preferably be connected to a movable carriage, so that the insertion element in the desired direction and position is movable.

Um das Einbringen des Folienüberstandes in den Bereich zwischen dem Gutstapel und dem Folienabschnitt zu vereinfachen, kann zur Beabstandung des Folienabschnittes von dem Gutstapel im umhüllten Zustand, vorzugsweise im Bereich des Folienabschnittes, der nach Einlegen des Folienüberstandes mit dem Folienüberstand in Kontakt steht, wenigstens eine Beabstandungseinrichtung vorgesehen sein. To the introduction of the film supernatant in the area to simplify between the stack and the film section, can for spacing the film section of the stack in the wrapped state, preferably in the area the film section, after inserting the film supernatant is in contact with the film supernatant, at least a spacing device may be provided.

Hierdurch wird ein Freiraum zwischen Folienabschnitt und Gutstapel geschaffen, so dass der Folienüberstand leichter einbringbar ist.This creates a space between film section and Good stack created so that the film supernatant easier can be introduced.

Dabei kann wenigstens eine Beabstandungseinrichtung als Saugeinrichtung ausgebildet sein. Die Saugeinrichtung wird außenseitig mit dem Folienabschnitt in Kontakt gebracht. Im Anschluss daran wird der Folienabschnitt bei Aktivierung von der Saugeinrichtung angesaugt. Durch Verfahren der Saugeinrichtung wird der Folienabschnitt von dem Gutstapel beabstandet.In this case, at least one spacing device as Be formed suction. The suction device is brought outside with the film section in contact. Following this, the film section is activated sucked by the suction device. By process the suction device is the film section of the stack spaced.

Wenigstens eine Beabstandungseinrichtung kann mit der dazugehörigen Verlagerungseinrichtung gekoppelt bewegbar sein. Hierdurch wird bei Verfahren einer der beiden Einrichtungen die andere Einrichtung entsprechend mitverfahren.At least one spacing device may be associated with it Displacement device coupled movable be. As a result, in the process of one of the two devices the other device according mitverfahren.

Die Verlagerungseinrichtung(en) und/oder die Beabstandungseinrichtung(en) kann (können) an einer vorzugsweise in vertikaler Richtung entlang des Gutstapels verfahrbaren Rahmenkonstruktion befestigt sein.The displacement device (s) and / or the spacer device (s) can (can) at a preferably movable in a vertical direction along the stack of goods Fixed frame construction.

Gegenstand der Erfindung ist ebenfalls ein Verfahren zum Einbringen von Folienüberständen. Beim Umhüllen von Gutstapeln mit Folienabschnitten, wie z.B. Stretchr- oder Schrumpfhauben, bilden sich im Bereich von zwei gegenüberliegenden Seitenkanten des Gutstapels an der Oberseite Folienüberstände. Diese gehen in etwa von den Ecken des Gutstapels aus und weisen insoweit eine im Wesentlichen dreieckförmige Form auf. Die Folienüberstände stehen dabei über die Seitenkanten über. The invention also provides a method for Introduction of film overhangs. When wrapping stacks of goods with film sections, e.g. Stretchr or Shrink hoods form in the area of two opposite ones Side edges of the stack of goods at the top Foil projections. These go from about the corners of the Good pile out and have so far essentially a triangular shape. The film overhangs are included over the side edges over.

Diese Folienüberstände, auch Zipfel oder Kapuzen genannt, müssen entweder an den Seiten oder an der Oberseite des Gutstapels fixiert werden, damit der umhüllte Gutstapel eine optisch ansprechende Umhüllung erhält. Als Nachteil erweist sich, dass die fixierten Folienüberstände sich z. B. beim Transport des Gutstapels selbstständig oder auch infolge eines Hängenbleibens an Vorsprüngen eines Transportmittels lösen können. Sofern eine Fixierung nur bereichsweise vorgenommen worden ist, kann dabei zudem noch der Folienabschnitt beschädigt werden, wodurch eine hinreichende Sicherung des Gutstapels unter Umständen nicht immer gewährleistet ist.These film overhangs, also called Zipfel or hoods, must be either on the sides or at the top of the Gutstapels be fixed so that the wrapped stack receives a visually appealing enclosure. As a disadvantage proves that the fixed film overhangs themselves z. B. independently or when transporting the stack also due to sticking to projections of a Can solve transport. Unless a fixation only In some areas, it can also still the film section will be damaged, creating a sufficient assurance of the good pile under circumstances not always guaranteed.

Aufgabe der Erfindung ist es daher, ein Verfahren anzugeben, mittels dessen die vorgenannten Nachteile bei einem mittels eines Folienabschnittes umhüllten Gutstapels vermieden werden.The object of the invention is therefore to specify a method by means of which the aforementioned disadvantages in a avoided by means of a foil section wrapped stack become.

Diese Aufgabe wird gelöst durch ein Verfahren zum Einbringen von Folienüberständen, eines einen Gutstapel seitlich und wenigstens teilweise oberseitig umhüllenden und in diesen Bereichen an dem Gutstapel anliegenden Folienabschnittes, insbesondere einer Folienhaube, wobei die Folienüberstände insbesondere dreiecksförmig ausgebildet und im Bereich zweier gegenüberliegender Kanten der Oberseite des Gutstapels angeordnet sowie in etwa von den Ecken des Gutstapels ausgehend sind, bei dem die seitlich über den Gutstapel überstehenden Folienüberstände nach dem Umhüllen des Gutstapels in den Bereich zwischen dem Gutstapel und dem Folienabschnitt eingebracht werden, dadurch gekennzeichnet, dass entweder wenigstens ein seitlich über den Gutstapel überstehender Folienüberstand in den Bereich zwischen dem Folienabschnitt und dem Gutstapel berührungslos durch einen Luftstrom eingebracht wird oder wenigstens ein seitlich über den Gutstapel überstehender Folienüberstand in den Bereich zwischen dem Folienabschnitt und dem Gutstapel mechanisch eingebracht wird. Hierdurch werden die Folienüberstände von den Folienabschnitten überdeckt, so dass diese sich auch beispielsweise bei einem Transport nicht mehr lösen. Zudem erhält der Gutstapel auch im Bereich der Folienüberstände eine glatte Oberfläche, da die Folienüberstände zwischen dem Folienabschnitt und dem Gutstapel angeordnet sind. Der Luftstrom kann beispielsweise mit einer Einblaseinrichtung auf den betreffenden Bereich des Folienüberstandes erzeugt und aufgebracht werden, so dass dieser in den Bereich zwischen dem Gutstapel und dem Folienabschnitt eingebracht wird. Das mechanische Einbringen kann beispielsweise mittels eines Einschiebelementes erfolgen, das den Folienüberstand zwischen dem Folienabschnitt und dem Gutstapel einschiebt.This object is achieved by a method for introducing of film overhangs, one of a stack of goods laterally and at least partially enveloping the upper side and in these areas on the stack of goods adjacent film section, in particular a film hood, wherein the film projections in particular triangular shaped and in the region of two opposite edges of the top the pile of goods arranged as well as from about the corners of Gutstapels are starting, in which the side over the Gutstapel protruding film overhangs after wrapping of the stack in the area between the stack and be introduced to the film section, characterized in that either at least one laterally over the stack of goods Film projection in the area between the film section and the stack of goods contactless by an air flow is introduced or at least one laterally over the stack overhanging film supernatant in the area between the film section and the stack of goods mechanically is introduced. This will cause the film overhangs covered by the film sections so that they themselves Also, for example, no longer solve a transport. In addition, the stack also receives in the area of film overhangs a smooth surface, as the film overhangs arranged between the film section and the stack are. The air flow can, for example, with a blowing device on the relevant area of the film supernatant be generated and applied so that this in the area between the stack and the film section is introduced. The mechanical introduction can, for example be done by means of a push-in, the the film supernatant between the film section and the Good pile inserts.

Dabei kann wenigstens ein seitlich über den Gutstapel überstehender Folienüberstand in den Bereich zwischen einer Seite des Gutstapels und dem Folienabschnitt eingebracht werden.In this case, at least one side over the stack projecting film supernatant in the area between a Side of the stack and the foil section introduced become.

Es kann aber auch wenigstens ein seitlich über den Gutstapel überstehender Folienüberstand in den Bereich zwischen der Oberseite des Gutstapels und dem Folienabschnitt eingebracht werden. Eine solche Maßnahme bietet sich an, wenn der Gutstapel auch für die Außenlagerung bestimmt ist, da infolge der horizontalen Ausrichtung des Folienüberstandes kein Regenwasser eindringen kann. But it can also be at least one side over the stack projecting film supernatant in the area between introduced the top of the stack and the film section become. Such a measure is useful if the stack is also intended for outdoor storage, since due to the horizontal orientation of the film supernatant no rainwater can penetrate.

Um das Einbringen zu erleichtern, kann zumindest der Bereich des Folienabschnittes, der nach Einbringen des Folienüberstandes mit dem Folienüberstand in Kontakt steht, zum Einbringen des Folienüberstandes von dem Gutstapel beabstandet werden. Aufgrund des so geschaffenen Freiraumes zwischen Folienabschnitt und Gutstapel kann der betreffende Folienüberstand problemlos eingebracht werden.To facilitate insertion, at least the area the film section, after introducing the film supernatant is in contact with the film supernatant, for introducing the film supernatant from the stack be spaced. Because of the created free space between film section and stack can the relevant Film supernatant be introduced easily.

Dabei kann zumindest der Bereich des Folienabschnittes, der nach Einbringen des Folienüberstandes mit dem Folienüberstand in Kontakt steht, zum Einbringen des Folienüberstandes durch Ansaugen von dem Gutstapel beabstandet werden.In this case, at least the region of the film section, after introducing the film supernatant with the film supernatant is in contact, for introducing the film supernatant be spaced by suction from the stack.

Wie insbesondere der Draufsicht in Fig. 1 zu entnehmen ist, bilden sich im Bereich der Schmalseiten des Gutstapels 1 im wesentlichen dreieckförmig ausgebildete Folienüberstände 5, wobei die Folienüberstände 5 in etwa von den Ecken des Gutstapels 1 ausgehen.As can be seen in particular from the top view in FIG is formed in the narrow sides of the pile of goods 1 substantially triangular shaped film projections 5, wherein the film projections 5 in about of the Go out corners of the stack 1.

Sofern es sich bei dem Folienabschnitt 3 um eine Schrumpffolie handelt, wird der Gutstapel 1 zunächst mittels einer nicht dargestellten Vorrichtung mit dem Folienabschnitt 3 umhüllt, wobei üblicherweise - wie in Fig. 8 gezeigt - der untere Rand des Folienabschnittes 3 nach unten über den Gutstapel 1 und die Palette 2 übersteht. Nicht dargestellt ist in den Figuren ebenfalls die spätere Schrumpfvorrichtung, mittels derer der Folienabschnitt 3 geschrumpft wird.If the film section 3 is a shrink film is, the stack 1 is first by means of a not shown device with the film section. 3 wrapped, wherein usually - as shown in Fig. 8 - the bottom edge of the film section 3 down over the Good stack 1 and the pallet 2 survives. Not shown is also the later shrinking device in the figures, by means of which the film section 3 shrunk becomes.

Bei Verwendung einer Stretchfolie als Folienabschnitt 3, wird dieser zunächst mittels einer nicht dargestellten Raffeinrichtung gerafft und im Anschluss daran in Umfangsrichtung vorgespannt. In diesem Zustand wird die Raffeinrichtung oder eine Überzieheinrichtung, sofern der geraffte und vorgespannte Folienabschnitt 3 von der Raffeinrichtung auf die Überzieheinrichtung übergeben worden ist, längs des Gutstapels 1 üblicherweise abwärts bewegt, wobei der geraffte Folienabschnitt 3 abgezogen wird und sich an den Außenseiten des Gutstapels 1 anlegt. Dabei wird üblicherweise der Gutstapel 1 mit der Palette 2 mittels einer nicht dargestellten Hubeinrichtung angehoben.When using a stretch film as film section 3, this is first by means of a not shown Ruffled and gathered in the circumferential direction biased. In this state, the shirring device or a pull-over device, if the shirred one and biased film section 3 of the shirring has been transferred to the overdrawing device, along the stack 1 usually moves down, where the shirred film section 3 is peeled off and on the outsides of the stack 1 applies. This is usually the stack 1 with the pallet 2 by means of a Lifting device not shown raised.

Zum Einbringen der Folienüberstände 5 zwischen dem Gutstapel 1 und dem Folienabschnitt 3 ist, wie in den Fig. 2 bis 7 dargestellt, beidseits des Gutstapels 1 je eine Verlagerungseinrichtung 6 vorgesehen. Jede Verlagerungseinrichtung 6 ist über einen Verfahrschlitten 7 mit einer oberhalb des Gutstapels 1 angeordneten Rahmenkonstruktion 8 verbunden.For introducing the film projections 5 between the stack 1 and the film section 3, as in Figs. 2 to 7, on both sides of the stack 1 each a displacement device 6 provided. Each relocation facility 6 is above a carriage 7 with an above the stack 1 arranged frame construction. 8 connected.

Die Rahmenkonstruktion 8 weist in etwa mittig einen Niederhalter 9 auf und ist in Richtung der Pfeile 10 in vertikaler Richtung verfahrbar.The frame structure 8 has a hold-down approximately in the middle 9 and is in the direction of arrows 10 in vertical Direction movable.

Die Verfahrschlitten 7 sind auf der Rahmenkonstruktion 8 verfahrbar, so dass die Verlagerungseinrichtungen 6 in Richtung der Pfeile 11 aufeinanderzubewegbar und so der Breite des jeweiligen Gutstapels 1 anpassbar sind.The carriages 7 are on the frame structure. 8 movable, so that the displacement devices 6 in Direction of the arrows 11 aufeinanderzubewegbar and so the Width of each stack 1 are customizable.

Jede Verlagerungseinrichtung 6 weist ein Einschiebelement 12 auf, das in dem dargestellten Ausführungsbeispiel vertikal ausgerichtet ist. An dem oberen Ende eines jeden Schiebelementes 12 ist ein Arm 13 angeformt, der das Schiebelement 12 mit einem Schlitten 14 verbindet. Jeder Schlitten 14 ist auf einer vertikal ausgerichteten Führungsschiene 15 in Richtung der Pfeile 16 verfahrbar gelagert. Jede Führungsschiene 15 wiederum ist mit dem betreffenden Verfahrschlitten 7 verbunden. Each displacement device 6 has an insertion element 12, which is vertical in the illustrated embodiment is aligned. At the top of each one Sliding element 12, an arm 13 is formed, which is the Sliding element 12 with a carriage 14 connects. Everyone Carriage 14 is on a vertically oriented guide rail 15 movably mounted in the direction of the arrows 16. Each guide rail 15 in turn is with the relevant Traversing slide 7 connected.

An dem unteren Ende jeder Führungsschiene 15 ist eine als Beabstandungseinrichtung ausgebildete Saugeinrichtung 17 vorgesehen. Bei der Saugeinrichtung 17 handelt es sich beispielsweise um einen Saugnapf. Die Saugeinrichtung 17 ist über einen Halter 18 mit der jeweiligen Führungsschiene 15 verbunden, so dass jede Saugeinrichtung 17 ebenfalls bei Verfahren des Verfahrschlittens 7 in Richtung der Pfeile 11 seitlich an den Gutstapel 1 herangefahren werden kann.At the lower end of each guide rail 15 is an as Spacing device formed suction device 17th intended. The suction device 17 is for example, a suction cup. The suction device 17 is via a holder 18 with the respective guide rail 15, so that each suction device 17 also when moving the carriage 7 in the direction of Arrows 11 are moved laterally to the stack 1 can.

Wie in Fig. 3 zu erkennen ist, wird zunächst die Rahmenkonstuktion 8 in Richtung des Pfeiles 10 abgesenkt, bis der Niederhalter 9 oberseitig den Gutstapel 1 berührt.As can be seen in Fig. 3, first the Rahmenkonstuktion 8 lowered in the direction of arrow 10 until the hold-9 touches the top of the stack 1.

Anschließend werden, wie in Fig. 4 dargestellt ist, die Verfahrschlitten 7 auf der Rahmenkonstruktion 8 in Richtung der Pfeile 11 seitlich an den Gutstapel 1 herangefahren, bis die Saugeinrichtungen 17 seitlich den Folienabschnitt 3 berühren.Subsequently, as shown in Fig. 4, the Traversing slide 7 on the frame structure 8 in the direction the arrows 11 moved laterally to the stack 1, until the suction devices 17 laterally the film section 3 touch.

In einem nächsten Schritt werden, wie in Fig. 5 dargestellt, die seitlichen Bereiche des Folienabschnittes 3 von den Saugeinrichtungen 17 angesaugt, wobei dann die Verfahrschlitten 7 und somit auch die Saugeinrichtungen 17 in Richtung der Pfeile 11 auseinanderbewegt werden. Hierdurch werden die Seitenbereiche des Folienabschnittes 3 von der Seite des Gutstapels 1 beabstandet. Im Anschluß daran werden die Einschiebelemente 12 in Richtung der Pfeile 16 abgesenkt, so dass die Folienüberstände 5 in den Bereich zwischen dem Folienabschnitt 3 und dem Gutstapel 1 eingeschoben werden. Es bietet sich dabei an, wenn die Form der Einschiebelemente 12 in etwa der Form des Folienüberstandes 5 entspricht. In a next step, as shown in FIG. 5, the lateral areas of the film section 3rd sucked by the suction devices 17, in which case the Traversing carriage 7 and thus also the suction devices 17th be moved apart in the direction of the arrows 11. hereby become the side portions of the film section 3rd spaced from the side of the stack 1. In connection Thereupon, the insertion elements 12 in the direction of Arrows 16 lowered, so that the film projections 5 in the Area between the film section 3 and the stack 1 be inserted. It is useful when the Shape of the insertion elements 12 in approximately the shape of the film supernatant 5 corresponds.

In Fig. 6 ist die Position der Einschiebelemente 12 in der tiefsten Stellung dargestellt, in der die Folienüberstände 5 vollständig in den Bereich zwischen dem Folienabschnitt 3 und dem Gutstapel 1 eingeschoben sind.In Fig. 6, the position of the insertion elements 12 in the shown lowest position in which the film projections 5 completely in the area between the film section 3 and the stack 1 are inserted.

Nach dem Einbringen der Folienüberstände 5 werden die Saugeinrichtungen 17 deaktiviert, so dass sich der Folienabschnitt 3 wieder seitlich an dem Gutstapel 1 anlegt. Ferner werden die Schlitten 14 auf den Führungsschienen 15 nach oben gefahren, so dass die Einschiebelemente 12 vertikal nach oben in Richtung der Pfeile 16 verschoben werden. Gleiches gilt für die Rahmenkonstruktion 8 (Pfeile 10), so dass der Niederhalter 9 nach dem Verfahren nicht mehr in Kontakt mit der Oberseite des Gutstapels 1 ist.After the introduction of the film projections 5 are the Deactivating means 17 deactivated, so that the film section 3 again applies laterally to the stack 1. Further, the carriages 14 on the guide rails 15th moved upwards, so that the insertion elements 12 vertically be moved upward in the direction of the arrows 16. The same applies to the frame structure 8 (arrows 10), so that the hold-9 is not after the process is more in contact with the top of the stack 1.

Aufgrund der Deaktivierung der Saugeinrichtung 16 liegt der Folienabschnitt 3 wieder seitlich an dem Gutstapel 1 an. Die Folienüberstände 5 sind, wie in Fig. 8 dargestellt, zwischen dem Folienabstand 3 und dem Gutstapel 1 angeordnet und werden hier sicher fixiert.Due to the deactivation of the suction device 16 is located the film section 3 again on the side of the stack 1 at. The film projections 5 are, as shown in Fig. 8, between the film gap 3 and the stack 1 arranged and are securely fixed here.

Es liegt auf der Hand, dass mittels dieser Vorrichtung auch ein Einbringen der Folienüberstände 5 in vertikaler Richtung, d.h. zwischen der Oberseite des Gutstapels 1 und dem Folienabschnitt 3 möglich ist. In diesem Fall muss lediglich die Anordnung aus Schiebelementen 12 und Saugeinrichtungen 17 derart vertauscht werden, dass die Saugeinrichtungen 17 den Folienabschnitt 3 von der Oberseite des Gutstapels 1 beabstanden und die Einschiebelemente 12 die Folienüberstände 5 in den Bereich zwischen dem Folienabschnitt 3 und der Oberseite des Gutstapels 1 einbringen können.It is obvious that by means of this device also an introduction of the film projections 5 in vertical Direction, i. between the top of the stack 1 and the film section 3 is possible. In this case, must only the arrangement of sliding elements 12 and suction devices 17 are reversed so that the suction 17 the film section 3 from the top the Gutstapels 1 space and the Einschiebelemente 12th the film projections 5 in the area between the film section Insert 3 and the top of the stack 1 can.
