Definitions
- the invention relates to a method for applying a film to a stack, in particular for shrinking a film onto a stack. Furthermore, the invention also relates to an apparatus for carrying out such a method.
- good stack in particular a plurality of packages, packages, sacks or the like units, which are preferably combined or stacked to form a rectangular stack of goods. It is within the scope of the invention that the stack is received on a pallet. Basically, however, good stacks can be used without a pallet. In principle, the stack of goods can also be only a few stacked units or even a single larger unit, for example from the white goods sector (washing machines, refrigerators, dishwashers and the like). It is further within the scope of the invention that the film is a plastic film and preferably a plastic shrink film which is heat-shrinkable under the influence of heat on the product stack. In this way, the stacked in the stack units are firmly held together and in particular secured against slipping or the like.
- a Foliendeckblatt is placed on the top of the stack and this Foliendeckblatt is about the upper edges of the stack by about 100 to about 300 mm.
- a foil band is placed around the sides of the stack, which are the protruding Encloses foil sections of the folio cover sheet.
- the film band is usually with overhang sections with a width of 50 to 400 mm on the upper edges of the stack over.
- the supernatant sections of the film band are then welded to the folio top sheet.
- the film band is first placed around the stack and folded with said protruding portions on the top of the stack and fixed there. Subsequently, the Foliendeckblatt is then placed and welded in a further step with the supernatant sections of the film band.
- the folded-over projecting portions of the film band are folded in three layers, in particular at the corners of the stack and therefore can heat only slowly or incompletely during the welding process. This results in leaking wrinkles and capillaries and this has the consequence that water can get from the side under the Foliendeckblatt. Above all, packaged paper products can thereby be treated with mold. Furthermore, air is also trapped between the foil cover sheet and the folded-over projecting portions of the foil band, so that a formation of bubbles occurs, which can rupture during stacking, so that even then water can penetrate.
- the invention the technical problem underlying a method of the type mentioned above, with which the disadvantages described above can be reliably and effectively avoided. Furthermore, the invention is based on the technical problem of specifying a device for carrying out such a method.

- the foil band and the foil cover are made of thermoplastic material. It is also within the scope of the invention that a shrinkage of the film band takes place on the stack under heat.
- the foil band it can be a film section, which is placed around the sides of the stack and at its two ends connected to each other, preferably welded. According to another embodiment, however, the foil band may also be a foil tube or a foil hood, which is pulled over the stack.
- the protruding portions of the film band and / or the foil sections of the folio cover sheet are present over the circumference of the stack or circulate over the circumference of the stack.
- the width b of the protrusion sections is 50 to 400 mm, and preferably the width B of the protruding film sections of the folio cover sheet is 100 to 300 mm.
- a heated or tempered press plate is used. It is recommended that the press plate is heated or tempered to a temperature which is below the melting temperature of the material or the plastic of the Foliendeckblattes. Conveniently, only a preheating of the folio cover sheet should be realized with the help of the pressed-press plate.
- the pressing plate is pressed onto the folio cover sheet with the proviso that air is pressed out or pressed out of the folded overhang sections of the foil band and / or air between the protrusion sections and the folio cover sheet. In this way, the disadvantageous air inclusions described above can be avoided at the top of the stack. Such air pockets can occur especially at the corners of the stack, at where the supernatant sections are usually folded in three layers or are folded onto the top.
- press plate which projects with press plate sections over the upper edges of the stack. Appropriately, it is horizontal or substantially horizontal projections or protruding press plate sections.
- the press plate then has a larger area than the top of the stack. It is recommended that the press plate has a larger area than the lying on the top of the stack of material Foliendeckblatt.
- the surface of the pressing plate can also correspond to the surface of the folio cover sheet.
- a particularly preferred embodiment of the invention is characterized in that the pressing plate forms the top or the ceiling of a shrinking chamber, wherein the shrinking chamber has side walls extending along the sides or along the lateral surfaces of the stack and wherein the hot air passes through the shrinking chamber Direction of the top of the stack or in the direction of pressure plate is passed.
- the press plate forms the upper end of the shrinking chamber in the pressed-on to the top of the stack of goods condition.
- shrinking chamber sections of the shrinking chamber are arranged distributed over the circumference of the stack of goods.
- the side walls of the shrinking chamber consist of vertically telescopic side wall sections. Then, the vertical extent of the side walls can be easily adapted to the height of the stack. Conveniently, upper sidewall portions of the vertically telescoping sidewall portions abut the press plate.
- upper banderole sections of the film banderole are heated with the rising hot air, so that these heated banderole sections can be welded to the heated film sections of the folio cover sheet.
- a simultaneous heating or heating takes place both the film sections of the Foliendeckblattes and the Banderolenabête in the upper region of the stack. In this way, an optimally tight or watertight welding between foil cover sheet and foil band can be achieved.
- a recommended embodiment of the method according to the invention is characterized in that the film sections initially hanging down at the upper edges of the stack are raised by means of the rising hot air and fall back to the sides of the stack as a result of the heating thereby taking place, where they are expediently welded to the heated band sections.
- the raised film sections thus lose stability due to the heating and therefore fall back to the sides of the stack, where they can be welded to the heated upper Banderolenabitesen.
- the invention is based on the finding that by the rising hot air, a negative pressure at the top of the edges of the raised Foliendeckblattes is generated. This negative pressure causes the film sections remain relatively long in the raised position and can be effectively heated there. When heating or heating of the film sections, the sections pull together in the direction of stack.
- the rising on the sides of the stack of hot air is generated with a surrounding the sides of the stack of hot air shrink frame.

- the hot air shrink frame is shut down so fast that remaining air is pushed out of the space between the film band and stack good down. It is recommended that subsequently a bottom foil of the stack is welded to the foil band by means of the hot air shrink frame. It is within the scope of the invention that this bottom foil is arranged between the pallet and the stack.
- the welding of the foil band with the bottom foil is also referred to as a "bottom shrinkage".
- An alternative embodiment of the invention provides that the position of the hot-air shrink frame for the "under-shrinking" or for welding the bottom film with the film band and the position of the shrink frame for the production of hot air for lifting the Foliendeckblattes or for welding the film sections This embodiment is particularly recommended for stacks with low height.
- a particularly well-proven embodiment of the invention is characterized in that the press plate is raised during the shrink-wrapping of the film band to the sides of the stack (side shrink) or during welding of the film band with the bottom foil (bottom shrink), so that the folio top sheet or the top of the folio top sheet is heated by the rising hot air.
- a heating space is thus generated above the stack of goods or above the folio cover sheet.
- the described heating of the foil cover sheet or the top side of the foil cover sheet preferably takes place with the proviso that there is no welding of the foil cover sheet with the folded-over projecting portions of the foil strip.
- the timing of lifting the squeeze plate during the process is selected.
- the foliar cover sheet is then cooled to the extent that it hangs tightly and without welding over the folded-over protrusion portions of the film band. Then creates a flat surface on the stack, so that here water or similar liquid can not accumulate easily.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Aufbringen einer Folie auf einen Gutstapel, insbesondere zum Aufschrumpfen einer Folie auf einen Gutstapel. Fernerhin betrifft die Erfindung auch eine Vorrichtung zur Durchführung eines solchen Verfahrens.The invention relates to a method for applying a film to a stack, in particular for shrinking a film onto a stack. Furthermore, the invention also relates to an apparatus for carrying out such a method.
Mit dem Begriff Gutstapel ist insbesondere eine Mehrzahl von Packungen, Paketen, Säcken oder dergleichen Einheiten gemeint, die vorzugsweise zu einem quaderförmigen Gutstapel kombiniert bzw. gestapelt sind. Es liegt im Rahmen der Erfindung, dass der Gutstapel auf einer Palette aufgenommen ist. Grundsätzlich können aber auch Gutstapel ohne Palette eingesetzt werden. Bei dem Gutstapel kann es sich prinzipiell auch nur um wenige gestapelte Einheiten handeln oder aber auch um eine einzelne größere Einheit, beispielsweise aus dem Weißwarenbereich (Waschmaschinen, Kühlschränke, Spülmaschinen und dergleichen). Es liegt fernerhin im Rahmen der Erfindung, dass es sich bei der Folie um eine Folie aus Kunststoff und vorzugsweise um eine Schrumpffolie aus Kunststoff handelt, die unter dem Einfluss von Wärme auf den Gutstapel aufschrumpfbar ist. Auf diese Weise werden die in den Gutstapel gestapelten Einheiten fest zusammengehalten und insbesondere gegen ein Verrutschen oder dergleichen gesichert.By the term good stack is meant in particular a plurality of packages, packages, sacks or the like units, which are preferably combined or stacked to form a rectangular stack of goods. It is within the scope of the invention that the stack is received on a pallet. Basically, however, good stacks can be used without a pallet. In principle, the stack of goods can also be only a few stacked units or even a single larger unit, for example from the white goods sector (washing machines, refrigerators, dishwashers and the like). It is further within the scope of the invention that the film is a plastic film and preferably a plastic shrink film which is heat-shrinkable under the influence of heat on the product stack. In this way, the stacked in the stack units are firmly held together and in particular secured against slipping or the like.
Aus der Praxis sind Verfahren der eingangs genannten Art in unterschiedlichen Ausführungsformen bekannt. So ist es unter anderem in der Papierindustrie bekannt aufgrund der unterschiedlichen Ladungsformate des Gutstapels die Verpackung wie folgt vorzunehmen. Zunächst wird ein Foliendeckblatt auf die Oberseite des Gutstapels gelegt und dieses Foliendeckblatt steht über die Oberkanten des Gutstapels um 100 bis ca. 300 mm über. Anschließend wird eine Folienbanderole um die Seiten des Gutstapels gelegt, die die überstehenden Folienabschnitte des Foliendeckblattes umschließt. Die Folienbanderole steht in der Regel mit Überstandsabschnitten mit einer Breite von 50 bis 400 mm über die Oberkanten des Gutstapels über. In einem weiteren Schritt werden dann die Überstandsabschnitte der Folienbanderole mit dem Foliendeckblatt verschweißt. Gemäß einer anderen bekannten Verfahrensweise wird zuerst die Folienbanderole um den Gutstapel gelegt und mit den genannten Überstandsabschnitten auf die Oberseite des Gutstapels gefaltet und dort fixiert. Anschließend wird dann das Foliendeckblatt aufgelegt und in einem weiteren Schritt mit den Überstandsabschnitten der Folienbanderole verschweißt.From practice, methods of the type mentioned in different embodiments are known. It is known, inter alia, in the paper industry due to the different charge formats of the stack of goods to make the packaging as follows. First, a Foliendeckblatt is placed on the top of the stack and this Foliendeckblatt is about the upper edges of the stack by about 100 to about 300 mm. Subsequently, a foil band is placed around the sides of the stack, which are the protruding Encloses foil sections of the folio cover sheet. The film band is usually with overhang sections with a width of 50 to 400 mm on the upper edges of the stack over. In a further step, the supernatant sections of the film band are then welded to the folio top sheet. According to another known procedure, the film band is first placed around the stack and folded with said protruding portions on the top of the stack and fixed there. Subsequently, the Foliendeckblatt is then placed and welded in a further step with the supernatant sections of the film band.
Beide vorstehend beschriebenen Verfahrensweisen zeichnen sich durch Nachteile aus. Die umgefalteten Überstandsabschnitte der Folienbanderole sind insbesondere an den Ecken des Gutstapels dreilagig gefaltet und können sich deshalb beim Schweißvorgang nur langsam bzw. unvollständig aufheizen. Dadurch entstehen undichte Falten und Kapillare und das hat zur Folge, dass Wasser von der Seite her unter das Foliendeckblatt gelangen kann. Vor allem verpackte Papierprodukte können dadurch mit Schimmel beaufschlagt werden. Fernerhin wird zwischen dem Foliendeckblatt und den umgefalteten Überstandsabschnitten der Folienbanderole auch Luft eingeschlossen, so dass eine Bildung von Blasen stattfindet, die beim Stapeln aufreißen können, so dass auch dann Wasser eindringen kann.Both methods described above are characterized by disadvantages. The folded-over projecting portions of the film band are folded in three layers, in particular at the corners of the stack and therefore can heat only slowly or incompletely during the welding process. This results in leaking wrinkles and capillaries and this has the consequence that water can get from the side under the Foliendeckblatt. Above all, packaged paper products can thereby be treated with mold. Furthermore, air is also trapped between the foil cover sheet and the folded-over projecting portions of the foil band, so that a formation of bubbles occurs, which can rupture during stacking, so that even then water can penetrate.
Demgegenüber liegt der Erfindung das technische Problem zugrunde, ein Verfahren der eingangs genannten Art anzugeben, mit dem die vorstehend beschriebenen Nachteile funktionssicher und effektiv vermieden werden können. Weiterhin liegt der Erfindung das technische Problem zugrunde, eine Vorrichtung zur Durchführung eines solchen Verfahrens anzugeben.In contrast, the invention, the technical problem underlying a method of the type mentioned above, with which the disadvantages described above can be reliably and effectively avoided. Furthermore, the invention is based on the technical problem of specifying a device for carrying out such a method.
Zur Lösung dieses technischen Problems lehrt die Erfindung ein Verfahren zum Aufbringen einer Folie auf einen Gutstapel, insbesondere zum Aufschrumpfen einer Folie bzw. einer Schrumpffolie auf einen Gutstapel, wobei zunächst eine Folienbanderole um über den Umfang des Gutstapels aneinander anschließende Seiten des Gutstapels gelegt wird, wobei an den Oberkanten des Gutstapels überstehende Überstandsabschnitte der Folienbanderole auf die Oberseite des Gutstapels umgefaltet werden und bevorzugt dort fixiert werden,
wobei anschließend ein Foliendeckblatt auf die Oberseite des Gutstapels und auf die umgefalteten Überstandsabschnitte der Folienbanderole aufgelegt wird, wobei das Foliendeckblatt mit Folienabschnitten über die Oberkanten des Gutstapels vorsteht bzw. übersteht, wobei daraufhin eine Pressplatte auf die Oberseite des Gutstapels bzw. auf das darauf aufliegende Foliendeckblatt aufgepresst wird,
wobei anschließend an den Seiten des Gutstapels Heißluft erzeugt wird, wobei die Heißluft entlang der Seiten des Gutstapels aufsteigt und die vorstehenden Folienabschnitte des Foliendeckblattes mit der Maßgabe erwärmt, dass die Folienabschnitte mit der an den Seiten des Gutstapels bzw. im Bereich der Oberseite des Gutstapels anliegenden Folienbanderole verschweißt werden. - Vorzugsweise ist der Gutstapel ein quaderförmiger Gutstapel mit vier Seiten, einer Oberseite und einem Boden. Die Folienbanderole wird dann um die vier Seiten des quaderförmigen Gutstapels gelegt.To solve this technical problem, the invention teaches a method for applying a film to a stack, in particular for shrinking a film or a shrink film on a stack, wherein first a film band is placed over the circumference of the stack of goods adjoining sides of the stack, wherein projecting at the upper edges of the stack of material supernatant portions of the film band are folded over to the top of the stack and are preferably fixed there,
wherein subsequently a Foliendeckblatt is placed on the top of the stack and on the folded overhang portions of the film band, wherein the Foliendeckblatt projecting with film sections on the upper edges of the stack or projects, whereupon a press plate on the top of the stack or on the lying thereon Foliendeckblatt is pressed on,
wherein hot air is then generated at the sides of the stack, wherein the hot air rises along the sides of the stack and heats the projecting film sections of Foliendeckblattes with the proviso that the film sections with the voltage applied to the sides of the stack or in the top of the stack Folienbanderole be welded. - Preferably, the stack is a cuboid stack with four sides, a top and a bottom. The foil band is then placed around the four sides of the block-shaped stack of goods.
Es liegt im Rahmen der Erfindung, dass die Folienbanderole und das Foliendeckblatt aus thermoplastischem Kunststoff bestehen. Es liegt weiterhin im Rahmen der Erfindung, dass ein Aufschrumpfen der Folienbanderole auf den Gutstapel unter Wärmeeinwirkung stattfindet. Bei der Folienbanderole kann es sich um einen Folienabschnitt handeln, der um die Seiten des Gutstapels gelegt wird und an seinen beiden Enden miteinander verbunden, bevorzugt verschweißt wird. Gemäß einer anderen Ausführungsform kann es sich bei der Folienbanderole aber auch um einen Folienschlauch oder um eine Folienhaube handeln, der bzw. die über den Gutstapel übergezogen wird.It is within the scope of the invention that the foil band and the foil cover are made of thermoplastic material. It is also within the scope of the invention that a shrinkage of the film band takes place on the stack under heat. With the foil band it can be a film section, which is placed around the sides of the stack and at its two ends connected to each other, preferably welded. According to another embodiment, however, the foil band may also be a foil tube or a foil hood, which is pulled over the stack.
Es liegt im Rahmen der Erfindung, dass die Überstandsabschnitte der Folienbanderole und/oder die Folienabschnitte des Foliendeckblattes über den Umfang des Gutstapels vorhanden sind bzw. über den Umfang des Gutstapels umlaufen. Zweckmäßigerweise beträgt die Breite b der Überstandsabschnitte 50 bis 400 mm und bevorzugt beträgt die Breite B der vorstehenden Folienabschnitte des Foliendeckblattes 100 bis 300 mm. Soweit bezüglich des Foliendeckblattes von vorstehenden Folienabschnitten die Rede ist, meint dies im Rahmen der Erfindung auch, dass die Folienabschnitte an den Seiten des Gutstapels herunterhängen können.It is within the scope of the invention that the protruding portions of the film band and / or the foil sections of the folio cover sheet are present over the circumference of the stack or circulate over the circumference of the stack. Advantageously, the width b of the protrusion sections is 50 to 400 mm, and preferably the width B of the protruding film sections of the folio cover sheet is 100 to 300 mm. As far as with respect to the Foliendeckblattes of the above film sections is mentioned, this means within the scope of the invention also that the film sections can hang down on the sides of the stack of goods.
Vorzugsweise wird im Rahmen der Erfindung mit einer erwärmten bzw. temperierten Pressplatte gearbeitet. Es empfiehlt sich, dass die Pressplatte auf eine Temperatur erwärmt bzw. temperiert wird, die unterhalb der Schmelztemperatur des Materials bzw. des Kunststoffes des Foliendeckblattes liegt. Zweckmäßigerweise soll mit Hilfe der aufgepressten Pressplatte lediglich eine Vorwärmung des Foliendeckblattes realisiert werden. - Gemäß bevorzugter Ausführungsform der Erfindung wird die Pressplatte mit der Maßgabe auf das Foliendeckblatt aufgepresst, dass Luft aus den umgefalteten Überstandsabschnitten der Folienbanderole und/oder Luft zwischen den Überstandsabschnitten und dem Foliendeckblatt herausgedrückt bzw. herausgepresst wird. Auf diese Weise können die eingangs beschriebenen nachteilhaften Lufteinschlüsse an der Oberseite des Gutstapels vermieden werden. Solche Lufteinschlüsse können vor allem an den Ecken des Gutstapels vorkommen, an denen die Überstandsabschnitte in der Regel dreilagig gefaltet sind bzw. auf die Oberseite gefaltet sind.Preferably, within the scope of the invention, a heated or tempered press plate is used. It is recommended that the press plate is heated or tempered to a temperature which is below the melting temperature of the material or the plastic of the Foliendeckblattes. Conveniently, only a preheating of the folio cover sheet should be realized with the help of the pressed-press plate. According to a preferred embodiment of the invention, the pressing plate is pressed onto the folio cover sheet with the proviso that air is pressed out or pressed out of the folded overhang sections of the foil band and / or air between the protrusion sections and the folio cover sheet. In this way, the disadvantageous air inclusions described above can be avoided at the top of the stack. Such air pockets can occur especially at the corners of the stack, at where the supernatant sections are usually folded in three layers or are folded onto the top.
Empfohlenermaßen wird mit einer Pressplatte gearbeitet, die mit Pressplattenabschnitten über die Oberkanten des Gutstapels vorsteht. Zweckmäßigerweise handelt es sich um horizontale bzw. im Wesentlichen horizontale Überstände bzw. vorstehende Pressplattenabschnitte. Die Pressplatte hat dann also eine größere Fläche als die Oberseite des Gutstapels. Es empfiehlt sich, dass die Pressplatte eine größere Fläche aufweist als das auf der Oberseite des Gutstapels aufliegende Foliendeckblatt. Grundsätzlich kann die Fläche der Pressplatte auch der Fläche des Foliendeckblattes entsprechen. - Eine besonders bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Pressplatte die Oberseite bzw. die Decke einer Schrumpfkammer bildet, wobei die Schrumpfkammer sich entlang der Seiten bzw. entlang der seitlichen Flächen des Gutstapels erstreckende Seitenwände aufweist und wobei die Heißluft durch die Schrumpfkammer in Richtung der Oberseite des Gutstapels bzw. in Richtung Pressplatte geleitet wird. Es liegt im Rahmen der Erfindung, dass die Pressplatte im auf die Oberseite des Gutstapels aufgepressten Zustand den oberen Abschluss der Schrumpfkammer bildet. Es liegt fernerhin im Rahmen der Erfindung, dass Schrumpfkammerabschnitte der Schrumpfkammer über den Umfang des Gutstapels verteilt angeordnet sind. Nach einer empfohlenen Ausführungsform der Erfindung bestehen die Seitenwände der Schrumpfkammer aus vertikal teleskopierbaren Seitenwandabschnitten. Dann kann die vertikale Erstreckung der Seitenwände auf einfache Weise an die Höhe des Gutstapels angepasst werden. Zweckmäßigerweise grenzen obere Seitenwandabschnitte der vertikal teleskopierbaren Seitenwandabschnitte an die Pressplatte an.It is recommended to work with a press plate which projects with press plate sections over the upper edges of the stack. Appropriately, it is horizontal or substantially horizontal projections or protruding press plate sections. The press plate then has a larger area than the top of the stack. It is recommended that the press plate has a larger area than the lying on the top of the stack of material Foliendeckblatt. In principle, the surface of the pressing plate can also correspond to the surface of the folio cover sheet. A particularly preferred embodiment of the invention is characterized in that the pressing plate forms the top or the ceiling of a shrinking chamber, wherein the shrinking chamber has side walls extending along the sides or along the lateral surfaces of the stack and wherein the hot air passes through the shrinking chamber Direction of the top of the stack or in the direction of pressure plate is passed. It is within the scope of the invention that the press plate forms the upper end of the shrinking chamber in the pressed-on to the top of the stack of goods condition. It is also within the scope of the invention that shrinking chamber sections of the shrinking chamber are arranged distributed over the circumference of the stack of goods. According to a recommended embodiment of the invention, the side walls of the shrinking chamber consist of vertically telescopic side wall sections. Then, the vertical extent of the side walls can be easily adapted to the height of the stack. Conveniently, upper sidewall portions of the vertically telescoping sidewall portions abut the press plate.
Es liegt im Rahmen der Erfindung, dass mit der aufsteigenden Heißluft obere Banderolenabschnitte der Folienbanderole erwärmt werden, so dass diese erwärmten Banderolenabschnitte mit den erwärmten Folienabschnitten des Foliendeckblattes verschweißt werden können. Zweckmäßigerweise findet also ein gleichzeitiges Erwärmen bzw. Aufheizen sowohl der Folienabschnitte des Foliendeckblattes als auch der Banderolenabschnitte im oberen Bereich des Gutstapels statt. Auf diese Weise kann eine optimal dichte bzw. wasserdichte Verschweißung zwischen Foliendeckblatt und Folienbanderole erreicht werden.It is within the scope of the invention that upper banderole sections of the film banderole are heated with the rising hot air, so that these heated banderole sections can be welded to the heated film sections of the folio cover sheet. Conveniently, therefore, a simultaneous heating or heating takes place both the film sections of the Foliendeckblattes and the Banderolenabschnitte in the upper region of the stack. In this way, an optimally tight or watertight welding between foil cover sheet and foil band can be achieved.
Eine empfohlene Ausführung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass die zunächst an den Oberkanten des Gutstapels herunterhängenden Folienabschnitte mittels der aufsteigenden Heißluft angehoben werden und als Folge der dadurch stattfindenden Aufheizung wieder an die Seiten des Gutstapels zurückfallen und dort zweckmäßigerweise mit den erwärmten Banderolenabschnitten verschweißt werden. Die angehobenen Folienabschnitte verlieren also aufgrund der Aufheizung an Stabilität und fallen deshalb an die Seiten des Gutstapels zurück, wo sie mit den erwärmten oberen Banderolenabschnitten verschweißt werden können. - Der Erfindung liegt dabei die Erkenntnis zugrunde, dass durch die aufsteigende Heißluft ein Unterdruck an der Oberseite der Ränder des angehobenen Foliendeckblattes erzeugt wird. Dieser Unterdruck bewirkt, dass die Folienabschnitte relativ lange in der angehobenen Position bleiben und dort effektiv aufgeheizt werden können. Beim Erwärmen bzw. Aufheizen der Folienabschnitte ziehen sich die Abschnitte in Richtung Gutstapel zusammen. Aufgrund dieses Schrumpfeffektes verändert sich das Flächen/GewichtsVerhältnis der Abschnitte. Nichtsdestoweniger bleiben die Folienabschnitte wegen des erzeugten Unterdruckes noch in der angehobenen Position bis sie gleichsam "teigig" werden und aufgrund mangelnde Stabilität an die Seiten des Gutstapels zurückfallen und dort mit den ebenfalls erwärmten Banderolenabschnitten verschweißen.A recommended embodiment of the method according to the invention is characterized in that the film sections initially hanging down at the upper edges of the stack are raised by means of the rising hot air and fall back to the sides of the stack as a result of the heating thereby taking place, where they are expediently welded to the heated band sections. The raised film sections thus lose stability due to the heating and therefore fall back to the sides of the stack, where they can be welded to the heated upper Banderolenabschnitten. - The invention is based on the finding that by the rising hot air, a negative pressure at the top of the edges of the raised Foliendeckblattes is generated. This negative pressure causes the film sections remain relatively long in the raised position and can be effectively heated there. When heating or heating of the film sections, the sections pull together in the direction of stack. Due to this shrinkage effect, the area / weight ratio of the sections changes. Nevertheless, due to the negative pressure generated, the film sections still remain in the raised position until they become "doughy" and due to lack of stability on the sides of the film Fall back pile of goods and there with the also heated Banderolenabschnitten weld.
Es liegt im Rahmen der Erfindung, dass die an den Seiten des Gutstapels aufsteigende Heißluft mit einem die Seiten des Gutstapels umgebenden Heißluft-Schrumpfrahmen erzeugt wird. Zweckmäßigerweise wird der Heißluft-Schrumpfrahmen bevorzugt vertikal in eine Position verfahren, in der die von dem Heißluft-Schrumpfrahmen aufsteigende Heißluft die Folienabschnitte des Foliendeckblattes bzw. die oberen Banderolenabschnitte effektiv für eine Verschweißung aufheizen kann. Es liegt weiterhin im Rahmen der Erfindung, dass der Heißluft-Schrumpfrahmen mit ausreichendem horizontalen Abstand bzw. horizontalen Sicherheitsabstand zu den Seiten des Gutstapels angeordnet ist. Es liegt fernerhin im Rahmen der Erfindung, dass die Folienbanderole mit dem Heißluft-Schrumpfrahmen auf den Gutstapel bzw. auf die Seiten des Gutstapels aufgeschrumpft wird. Bei diesem Aufschrumpfen auf die Seiten des Gutstapels spricht man auch von dem sogenannten "Seitenschrumpf".It is within the scope of the invention that the rising on the sides of the stack of hot air is generated with a surrounding the sides of the stack of hot air shrink frame. The hot air shrink frame is expediently moved vertically into a position in which the hot air rising from the hot air shrink frame can effectively heat the foil sections of the folio cover sheet or the upper band sections for welding. It is also within the scope of the invention that the hot-air shrink frame is arranged with sufficient horizontal distance or horizontal safety distance to the sides of the stack. It is also within the scope of the invention that the film band is shrunk with the hot air shrink frame on the stack or on the sides of the stack of goods. In this shrinking on the sides of the stack of goods is also called the so-called "side shrink".
Empfohlenermaßen wird der Heißluft-Schrumpfrahmen nach der Erwärmung der vorstehenden Folienabschnitte des Foliendeckblattes bzw. nach der Erwärmung der oberen Banderolenabschnitte entlang der Seiten des Gutstapels nach unten verfahren. Zweckmäßigerweise wird der Heißluft-Schrumpfrahmen dabei so schnell heruntergefahren, dass verbleibende Luft aus dem Zwischenraum zwischen Folienbanderole und Gutstapel nach unten hin herausgedrückt wird. Es empfiehlt sich, dass im Anschluss daran eine Bodenfolie des Gutstapels mit Hilfe des Heißluft-Schrumpfrahmens mit der Folienbanderole verschweißt wird. Es liegt im Rahmen der Erfindung, dass diese Bodenfolie zwischen der Palette und dem Gutstapel angeordnet ist. Das Verschweißen der Folienbanderole mit der Bodenfolie bezeichnet man auch als "Unterschrumpf'.Empfohlenermaßen the hot air-shrink frame is moved after the heating of the protruding film sections of the Foliendeckblattes or after the heating of the upper banderole sections along the sides of the stack of goods down. Conveniently, the hot air shrink frame is shut down so fast that remaining air is pushed out of the space between the film band and stack good down. It is recommended that subsequently a bottom foil of the stack is welded to the foil band by means of the hot air shrink frame. It is within the scope of the invention that this bottom foil is arranged between the pallet and the stack. The welding of the foil band with the bottom foil is also referred to as a "bottom shrinkage".
Eine alternative Ausführungsform der Erfindung sieht vor, dass die Position des Heißluft-Schrumpfrahmens für den "Unterschrumpf' bzw. für das Verschweißen der Bodenfolie mit der Folienbanderole auch der Position des Schrumpfrahmens für die Erzeugung der Heißluft zum Anheben des Foliendeckblattes bzw. zum Verschweißen der Folienabschnitte des Foliendeckblattes mit den Banderolenabschnitten entspricht. Diese Ausführungsform empfiehlt sich insbesondere für Gutstapel mit geringer Höhe.An alternative embodiment of the invention provides that the position of the hot-air shrink frame for the "under-shrinking" or for welding the bottom film with the film band and the position of the shrink frame for the production of hot air for lifting the Foliendeckblattes or for welding the film sections This embodiment is particularly recommended for stacks with low height.
Eine besonders bewährte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Pressplatte während des Aufschrumpfens der Folienbanderole an die Seiten des Gutstapels (Seitenschrumpf) bzw. während des Verschweißens der Folienbanderole mit der Bodenfolie (Unterschrumpf) angehoben wird, so dass das Foliendeckblatt bzw. die Oberseite des Foliendeckblattes von der aufsteigenden Heißluft erwärmt wird. Durch das Anheben der Pressplatte wird also gleichsam ein Aufheizungsraum über dem Gutstapel bzw. über dem Foliendeckblatt erzeugt. Vorzugsweise erfolgt die beschriebene Erwärmung des Foliendeckblattes bzw. der Oberseite des Foliendeckblattes mit der Maßgabe, dass keine Verschweißung des Foliendeckblattes mit den umgefalteten Überstandsabschnitten der Folienbanderole stattfindet. In Abhängigkeit davon wird der Zeitpunkt des Anhebens der Pressplatte während des Verfahrens ausgewählt. Vorzugsweise wird das Foliendeckblatt dann mit der Maßgabe abgekühlt, dass es sich stramm und ohne Verschweißung über die umgefalteten Überstandsabschnitte der Folienbanderole auflegt. Dann entsteht eine plane Oberfläche auf dem Gutstapel, so dass sich hier Wasser oder dergleichen Flüssigkeit nicht ohne Weiteres ansammeln kann. Insoweit zeichnet sich diese Ausführungsform im Vergleich zu den eingangs beschriebenen bekannten Verfahren durch einen beachtlichen Vorteil aus. Gegenstand der Erfindung ist auch eine Vorrichtung zum Aufbringen einer Folie auf einen Gutstapel, insbesondere zum Aufschrumpfen einer Folie bzw. Schrumpffolie auf einen Gutstapel, wobei eine Einrichtung zum Aufbringen einer Folienbanderole auf die Seiten des Gutstapels vorgesehen ist, wobei weiterhin eine Pressplatte zum Aufdrücken eines Foliendeckblattes auf die Oberseite des Gutstapels und auf umgefaltete Überstandsabschnitte der Folienbanderole vorhanden ist und wobei fernerhin eine Einrichtung zur Erzeugung von an den Seiten des Gutstapels aufsteigender Heißluft zur Verschweißung von vorstehenden Folienabschnitten des Foliendeckblattes mit oberen Banderolenabschnitten vorgesehen ist.A particularly well-proven embodiment of the invention is characterized in that the press plate is raised during the shrink-wrapping of the film band to the sides of the stack (side shrink) or during welding of the film band with the bottom foil (bottom shrink), so that the folio top sheet or the top of the folio top sheet is heated by the rising hot air. As a result of the lifting of the pressing plate, a heating space is thus generated above the stack of goods or above the folio cover sheet. The described heating of the foil cover sheet or the top side of the foil cover sheet preferably takes place with the proviso that there is no welding of the foil cover sheet with the folded-over projecting portions of the foil strip. Depending on this, the timing of lifting the squeeze plate during the process is selected. Preferably, the foliar cover sheet is then cooled to the extent that it hangs tightly and without welding over the folded-over protrusion portions of the film band. Then creates a flat surface on the stack, so that here water or similar liquid can not accumulate easily. In that regard, this embodiment is characterized by a considerable advantage compared to the known methods described above. The invention also provides a device for applying a film to a stack, in particular for shrinking a film or shrink film on a stack, wherein a device for applying a film band is provided on the sides of the stack, wherein further comprises a press plate for pressing a Foliendeckblattes on the top of the stack and on folded over protrusion portions of the film band is present and further wherein a means for generating rising on the sides of the stack of hot air for welding of protruding film sections of the Foliendeckblattes is provided with upper Banderolenabschnitten.
