Eine solche Vorrichtung zum Herstellen und Umhüllen von Schmelzkleberportionen ist aus der DE 196 32 787 A1 bekannt. Die bekannte Vorrichtung ist als Doppelbandanlage gestaltet, wobei auf einem unteren Förderband eine Gittermatrix mitlaufend angeordnet ist. Das obere Band der Doppelbandanlage dient zur Kalibrierung der in die Aussparungen der Gittermatrix eingebrachten Schmelzenportionen. Die Schmelzenportionen werden über einen Gießkopf im pasteusen Zustand den Aussparungen der Matrix zugeführt. Sowohl der Gittermatrix und damit dem unteren Förderband, als auch dem oberen Kalibrierband ist jeweils eine Folienbahn zugeordnet, die mit dem jeweiligen Ober- bzw. Untertrum der beiden Bänder der Doppelbandanlage mitgeführt wird und in einem an die Doppelbandanlage anschließenden Prozeßbereich durch Längs- und Querschneideinrichtungen zu Folienzuschnitten für die jeweiligen Schmelzenportionen verändert wird. Die obere und die untere Folie liegen um die Schmelzenportionen herum aneinander an, so daß sie einen dichten Abschluß für die Schmelzenportionen bilden.Such a device for producing and wrapping Hot melt adhesive portions are known from DE 196 32 787 A1. The known device is designed as a double belt system, a grid matrix running along on a lower conveyor belt is arranged. The upper belt of the double belt system is used to calibrate the recesses in the grid matrix introduced melt portions. The melt portions the recesses are pasted over a pouring head fed to the matrix. Both the grid matrix and thus the lower conveyor belt as well as the upper calibration belt a film web is assigned to each one, with the respective Upper or lower run of the two belts of the double belt system is carried and in a subsequent to the double belt system Process area through longitudinal and cross cutting devices to film cuts for the respective melt portions is changed. The upper and the lower foil lie around the melt portions so that they form a tight seal for the melt portions.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, die mit einfachen Mitteln die Bereitstellung von verpackten Schmelzenportionen ermöglicht.The object of the invention is a device of the beginning to create the kind that is provided with simple means of packaged melt portions.

Diese Aufgabe wird dadurch gelöst, daß in Förderrichtung hinter der Querschneidvorrichtung Mittel zum Umschlagen der Folienränder der Folienzuschnitte auf die jeweilige Schmelzenportion angeordnet sind, und daß Mittel zum Zusammenklappen jeder Schmelzenportion etwa auf die Hälfte ihrer Längs- oder Quererstreckung und etwa auf das Doppelte ihrer Dicke vorgesehen sind. Durch die erfindungsgemäße Lösung ist es möglich, mit einer einzelnen Folienbahn und damit mit einer einzelner. Folienzuführeinrichtung auszukommen, da durch die Doublierung jeder Schmelzenportion aufgrund des Zusammenklappens und des zuvor erfolgten Umschlagens der Folienränder auf die jeweilige Schmelzenportion eine vollständige Umhüllung der jeweiligen Schmelzenportion mittels der einzelnen Folienbahn bzw. des jeweils einzelnen Folienzuschnittes erzielt wird. Als Mittel zum Umschlagen können insbesondere Blasvorrichtungen vorgesehen sein, die derart auf die Folienränder gerichtet werden, daß das Umschlagen auf die Schmelzenportion erfolgt. This object is achieved in that behind in the conveying direction the cross-cutting device means for turning over the film edges the film cuts to the respective melt portion are arranged, and that means for collapsing each melt portion about half of its length or Transverse extent and provided approximately twice their thickness are. The solution according to the invention makes it possible to with a single film web and thus with a single. Foil feeder to get by because of the duplication each melt portion due to the collapse and the the foil edges were previously folded over onto the respective one Melt portion a complete coating of the respective Melt portion by means of the individual film web or of each individual film cut is achieved. As Means for turning over can in particular blow devices be provided, which are directed towards the edges of the film be that the changeover to the melt portion takes place.

Voraussetzung für die erfindungsgemäße Lösung ist es, daß die Schmelze in so weit fließfähigem Zustand in die jeweilige Aussparung der Gittermatrix eingefüllt wird, daß aufgrund der Fließeigenschaften der Schmelze diese den gesamten Raum der Aussparung einnimmt. Die Abkühlung der Schmelzenportionen erfolgt nur so weit, daß die Schmelze sich noch in einem weichen Zustand befindet, um ein Zusammenklappen ohne Schwierigkeiten zu ermöglichen. Beim Vorsehen eines Schmelzklebers erfolgt die Abkühlung etwa auf Raumtemperatur, da der Schmelzkleber bei Raumtemperatur noch ausreichend weich ist. Selbstverständlich muß die Schmelze jedoch eine Temperatur aufweisen, die unter der Schmelztemperatur der Folie liegt.A prerequisite for the solution according to the invention is that the Melt in the respective flowable state as far as possible Recess of the grid matrix is filled in that due to the Flow properties of the melt this the entire space of the Takes recess. The melt portions are cooled only so far that the melt is still soft Condition located to collapse without difficulty to enable. If a hot melt adhesive is provided cooling down to room temperature because of the hot melt adhesive is still sufficiently soft at room temperature. Of course however, the melt must have a temperature which is below the melting temperature of the film.

In Ausgestaltung der Erfindung ist jede Aussparung der Gittermatrix mit einer die Fläche der Aussparung halbierenden Leiste versehen. Die Leiste weist vorzugsweise eine geringere Höhe als der Rand der zugehörigen Aussparung auf. In dem Bereich der Aussparung, in dem die Leiste vorgesehen ist, ist die jeweilige Schmelzenportion entsprechend nutartig ausgespart, so daß dieser Gratbereich eine Klappachse nach Art eines Filmscharnieres bilden kann, wenn die entsprechend gebildeten Schmelzenportionhälften, die über den Gratbereich noch miteinander verbunden sind, zusammengeklappt werden.In one embodiment of the invention, each recess is the grid matrix with a halving the area of the recess Provide bar. The bar preferably has a lower one Height as the edge of the corresponding recess. In that area the recess in which the bar is provided the respective melt portion is cut out in a groove-like manner, so that this ridge area is a folding axis like a Film hinge can form if the appropriately formed Melt portion halves that still over the ridge area are connected together, can be folded.

Vorteilhaft ist die Leiste einstückiger Bestandteil der Gittermatrix. Dadurch kann die Gittermatrix unter Bildung der Leiste in einem einstufigen Arbeitsgang hergestellt werden. Vorzugsweise ist die Gittermatrix aus einer harten Elastomermischung hergestellt. Die Gittermatrix ist vorzugsweise als endlos umlaufendes Band gestaltet.The bar is advantageously an integral part of the grid matrix. This allows the lattice matrix to form the Moldings can be produced in a single step. The grid matrix is preferably made of a hard elastomer mixture manufactured. The grid matrix is preferably as endless belt.

In weiterer Ausgestaltung der Erfindung sind eingangsseitige Mittel zum flächigen Einbetten der Folie in die Aussparungen der Gittermatrix vorgesehen. Dies kann durch entsprechende chemische Behandlung oder durch elektrostatische Aufladung erfolgen. In a further embodiment of the invention, the input side Means for embedding the film in the recesses the grid matrix provided. This can be done by appropriate chemical treatment or by electrostatic charge respectively.

Besonders vorteilhaft weisen die Mittel zum Einbetten eine Ansaugeinrichtung auf, die die Folie von unten her auf die Gittermatrix und in die Aussparungen zieht. Dadurch wird vorzugsweise zwischen dem Förderband und der Gittermatrix, wobei das Förderband vorzugsweise als Stahlband gestaltet ist, ein Vakuum geschaffen, das die entsprechende Folienbahn flächig in die Aussparungen einsaugt.The means for embedding are particularly advantageous Intake device that the film from below on the Grid matrix and pulls into the recesses. This is preferred between the conveyor belt and the grid matrix, where the conveyor belt is preferably designed as a steel belt Vacuum created that the corresponding film sheet flat sucked into the recesses.

Eine Vorrichtung 1 zum Herstellen und Umhüllen von Schmelzkleberportionen weist ein einzelnes Förderband 2 in Form eines umlaufenden Stahlbandes auf, auf dessen Oberfläche umlaufend eine aus einem elastischen Material hergestellte Gittermatrix 3 angeordnet ist, die gemeinsam mit dem Förderband 2 in Förderrichtung F mitläuft. Der Gittermatrix 3 und damit auch dem Stahlband 2 wird von oben her eine in einem beheizten Vorratsbehälter 7 in fließfähigem Zustand gelagerte Schmelze über eine Pumpvorrichtung 6 und eine Portioniervorrichtung 4 in abgestimmten Schmelzenportionen (nachfolgend näher beschrieben) zugeführt. Vor dem Zuführen der Schmelzenportionen wird auf die Gittermatrix 3 eine Folienbahn 9 mittels einer Folienzuführeinrichtung 8 aufgebracht, so daß die Schmelzenportionen beim Einfüllen in entsprechende Aussparungen der Gittermatrix auf der Folienbahn 9 aufgefangen werden. Die Folienbahn 9 wird mittels der Folienzuführeinrichtung 8 ohne Zugspannung der Gittermatrix 3 zugeführt, damit die Folienbahn sich in die Aussparungen der Gittermatrix 3 einbetten kann. Damit die Folienbahn 9 die Aussparungen der Gittermatrix bündig anliegend auskleiden kann, ist vor der Portioniervorrichtung 4 als Mittel zum Einbetten eine Ansaugvorrichtung 10 vorgesehen, deren Positionierung in Fig. 1 lediglich schematisiert dargestellt ist. Diese Ansaugvorrichtung 10 weist Ansaugdüsen auf, die unterhalb der Folienbahn 9, vorzugsweise im Zwickel des Eingangsbereiches zwischen der Zuführung der Folienbahn 9 und der Trommelumlenkung des Stahlbandes 2 und der Gittermatrix 3 positioniert sind, so daß in den entsprechenden Aussparungen der Gittermatrix, die dicht auf dem Stahlband aufliegt, ein Unterdruck erzielt wird, der die Folienbahn in die Aussparungen einzieht.A device 1 for producing and wrapping portions of hot melt adhesive has a single conveyor belt 2 in the form of a encircling steel band, on its surface encircling a lattice matrix made of an elastic material 3 is arranged, which together with the conveyor belt 2 runs in the direction of conveyance F. The grid matrix 3 and thus The steel strip 2 is also heated from above Storage container 7 stored in a flowable state Melt via a pump device 6 and a portioning device 4 in coordinated melt portions (below described in more detail) supplied. Before feeding the melt portions is a film web 9 by means of the grid matrix 3 a film feeder 8 applied so that the Portions of melt when pouring into corresponding recesses the grid matrix can be caught on the film web 9. The film web 9 is made by means of the film feed device 8 supplied without tension to the grid matrix 3, so that the film web embed in the recesses of the lattice matrix 3 can. So that the film web 9 the recesses of the grid matrix can line up flush before the portioning device 4 as a means of embedding a suction device 10 provided, their positioning in Fig. 1 only is shown schematically. This suction device 10 has suction nozzles located below the film web 9, preferably in the gusset of the entrance area between the Feeding the film web 9 and the drum deflection of the Steel strip 2 and the grid matrix 3 are positioned so that in the corresponding recesses of the lattice matrix, the rests tightly on the steel belt, creates a vacuum that pulls the film web into the recesses.

Um zu verhindern, daß die mittels der Portioniervorrichtung 4 zugeführte Schmelze die Folienbahn 9 zum Schmelzen bringt, wird die Schmelze vor der Portioniervorrichtung 4 mittels eines Wärmetauschers 5 auf eine Temperatur konditioniert, die unterhalb des Schmelzpunktes der Folienbahn 9 liegt. In order to prevent the portioning device 4 supplied melt causes the film web 9 to melt, the melt is in front of the portioning device 4 by means of a Heat exchanger 5 conditioned to a temperature that is below the melting point of the film web 9.

Die Vorrichtung 1 weist - in Förderrichtung F an die Portioniervorrichtung 4 anschließend - verschiedene Kühlmittel 11, 12 auf, die über eine definierte Kühllänge des Förderbandes 2 sowohl von unten her als auch von oben her eine Abkühlung der Schmelzenportionen bewirken. Ausgangsseitig des Förderbandes 2 wird die Folienbahn 9 einschließlich der darauf befindlichen Schmelzenportionen auf ein kleineres Förderband 17 geführt, dem eine Querschneideinrichtung 13 und eine Längsschneideinrichtung 14 zugeordnet sind. Zudem ist als Mittel zum Umschlagen eines Blasvorrichtung 15 angeschlossen, die mittels mehrerer, geeignet positionierter Ausblasdüsen ein Umschlagen der durch die Quer- und Längsschneidvorrichtungen 13, 14 geschaffenen freien Folienränder entsprechender Folienzuschnitte auf die jeweilige Schmelzenportion bewirkt. In einem anschließenden Förderbandabschnitt 18 wird jede Schmelzenportion 19 mittels einer Zusammenlegvorrichtung 16 oder manuell doubliert, indem sie ähnlich einem zunächst aufgeschlagenen Buch zusammengeklappt wird. Dabei kommen allseitig die umgeschlagenen Folienränder aufeinanderzuliegen. Aufgrund der Klebeeigenschaften des Schmelzklebers verbleiben die Schmelzkleberportionen in ihrem zusammengeklappten Zustand und sind für entsprechende Lagerung oder entsprechenden Transport sicher umhüllt. Bei einer späteren Benutzung zur Bildung eines Schmelzenbades schmilzt die Folie rückstandslos auf.The device 1 points in the conveying direction F to the portioning device 4 then - various coolants 11, 12, which over a defined cooling length of the conveyor belt 2 cooling both from below and from above Effect melt portions.

In In this case, the crossbars of the lattice matrix 3 are the separate individual recesses 20 from one another on their underside each with a corresponding groove, through which the respective inguinal band is flush with the bottom the grid matrix 3 can be integrated. Each bar 21 has one smaller height than the thickness of the grid matrix 3. Thereby shows the melt 22 according to FIGS. 3 and 4 in the area each bar 21 has a smaller thickness after being filled on.

Es ist auch möglich, daß die Leiste 21 die gleiche Höhe wie die Ränder der Aussparung 20 und damit der Gittermatrix 3 aufweisen oder sogar etwas höher gestaltet sind. In diesem Fall sammelt sich auf Höhe der Leiste 21 gar keine Schmelze an. Dennoch kann ein anschließendes Zusammenklappen in Pfeilrichtung D erfolgen, da die Folie im Bereich der jeweiligen Leiste 21 nach Art eines Filmscharnieres wirkt. Bei der Darstellung nach den Fig. 3 und 4 wirkt ergänzend auch noch der entsprechende Schmelzenfilm 24 (Fig. 5 und 6), der sich im Bereich der Leiste 21 befindet, als zusätzliches Filmscharnier.It is also possible that the bar 21 is the same height as the edges of the recess 20 and thus the grid matrix 3 have or are designed somewhat higher. In this Fall does not collect any melt at level 21 on. Nevertheless, a subsequent folding in the direction of the arrow D done because the film in the area of each Strip 21 acts like a film hinge. In the presentation 3 and 4 also acts in addition corresponding melt film 24 (FIGS. 5 and 6), which is in the Area of the bar 21 is located as an additional film hinge.

In Fig. 4 ist die Funktion der nicht dargestellten Ausblasdüsen der Blasvorrichtung 15 dargestellt, die die auf der Gittermatrix 3 aufliegenden Folienränder 23 zunächst anheben und durch entsprechende Ausrichtung der Ausblasdüsen in Pfeilrichtung U auf die jeweilige Schmelzenportion 22 blasen, wo sie aufgrund der Klebeeigenschaften der Schmelzenportion haften bleiben. Das anschließende Zusammenklappen in Pfeilrichtung D mittels der Zusammenlegvorrichtung 16 erfolgt durch eine schaufelartige Hebevorrichtung, die wenigstens eine Seite der jeweiligen Schmelzenportion 22, 23 anhebt und auf die andere Hälfte umklappt. Es ist auch möglich, gemäß Fig. 1 zwei entsprechende Hebeplatten vorzusehen, die gleichzeitig beide Hälften der Schmelzenportion anheben und vertikal zusammenklappen. Anschließend wird die zusammengeklappte Schmelzenportion abgelegt.In Fig. 4 is the function of the blow nozzles, not shown the blowing device 15 shown that on the grid matrix First lift 3 overlying film edges 23 and by aligning the blow nozzles in the direction of the arrow U blow onto the respective melt portion 22 where they stick due to the adhesive properties of the melt portion stay. The subsequent folding in the direction of the arrow D by means of the folding device 16 a scoop-like lifting device, the at least one side the respective melt portion 22, 23 raises and on the other half folded down. It is also possible, according to FIG. 1 provide two corresponding lifting plates, the same Lift both halves of the melt portion and fold them up vertically. Then the folded portion of melt filed.

Anhand der Fig. 6 ist erkennbar, daß die Quer- und Längsschneidvorrichtungen 13, 14 jeden Folienzuschnitt für die zugeordnete Schmelzenportion 22 derart dimensionieren, daß um die Schmelzenportion 22 herum umlaufend Folienränder 23 verbleiben. Diese werden mittels der Blasvorrichtung 15 oder anderer, geeigneter Umschlagmittel auf die Schmelze 22 umgeschlagen. Anschließend wird die Schmelzenportion 19 in Pfeilrichtung D zusammengelegt, d.h. doubliert, wodurch umlaufend die entsprechend umgeschlagenen Folienränder 23 aufeinander zu liegen kommen. Die Schmelze, vorliegend der Schmelzkleber 22, ist somit vollständig von dem Folienzuschnitt eingeschlagen und somit ohne Schwierigkeiten für die weitere Verwendung handhabbar.6 that the transverse and longitudinal cutting devices 13, 14 each foil cut for the assigned one Dimension melt portion 22 such that around the melt portion 22 all around the film edges 23 remain. These are by means of the blowing device 15 or other, suitable transshipment means handled on the melt 22. Then the melt portion 19 in the direction of the arrow D merged, i.e. relocated, which means all-round the correspondingly folded film edges 23 on top of each other come to rest. The melt, here the hot melt adhesive 22, is thus completely wrapped in the film blank and therefore without difficulty for further use manageable.
