Description

Die vorliegende Erfindung betrifft eine Kanten-Anleimvorrichtung für den mobilen Einsatz zum Anbringen eines bandförmigen Kantenmaterials an die Kantenfläche eines plattenförmigen Werkstücks, mit einem Kleberbehälter zur Aufnahme eines Schmelzklebers, wobei der Kleberbehälter eine Schmelzkammer und eine Förderkammer aufweist, einer im Kleberbehälter vorgesehenen Heizeinrichtung mit zumindest einem Heizelement zum Schmelzen des Schmelzklebers, und einer angetriebenen Auftragswalze mit einem ersten Längsabschnitt, der zum Auftragen des Schmelzklebers auf das Kantenmaterial und/oder die Kantenfläche des Werkstücks ausgelegt ist, und einem zweiten Längsabschnitt, der in die Förderkammer des Kleberbehälter ragt, um Schmelzkleber zum ersten Längsabschnitt zu transportieren.The present invention relates to an edge-gluing device for mobile use for attaching a band-shaped edge material to the edge surface of a plate-shaped workpiece, with an adhesive container for receiving a hot melt adhesive, wherein the adhesive container has a melting chamber and a delivery chamber, a heating device provided in the adhesive container with at least one A heating element for melting the hot melt adhesive, and a driven applicator roll having a first longitudinal portion, which is designed for applying the hot melt adhesive to the edge material and / or the edge surface of the workpiece, and a second longitudinal portion which projects into the delivery chamber of the adhesive container to the hot melt adhesive to the first Longitudinal section to transport.

Kanten-Anleimvorrichtungen der vorgenannten Art sind allgemein bekannt. Beispielsweise offenbart die DE 20 2006 000 747 U1 eine tragbare Anleimeinrichtung, die eine Auftragseinheit umfasst, die eine Schmelzkammer und eine Lagerbuchse aufweist, wobei die Auftragseinheit über wenigstens ein Getriebe an eine Antriebseinheit angeschlossen ist, und wobei die Schmelzkammer einen Austragshohlraum aufweist, in dem sich eine drehbare Auftragswalze befindet. Der in der Schmelzkammer aufgeschmolzene Kleber gelangt bei dieser Anleimeinrichtung in den Austragshohlraum, wo er durch die Drehung der Auftragswalze und entsprechende Elemente an der Wand des Hohlraums nach oben in jenen Bereich gefördert wird, in dem das Kantenmaterial an der Auftragswalze vorbeiläuft und mit Kleber versehen wird (Auftragsbereich). Der Kleber ist vor der Benutzung in die Schmelzkammer zu geben, wo er vollständig aufgeschmolzen werden muss. Das kann einige Zeit in Anspruch nehmen, was unerwünscht ist. Darüber hinaus lässt sich das Volumen der Schmelzkammer auch nicht weiter vergrößern, da dann diese Wartezeit noch weiter ansteigen würde. Zudem kann auch während des Betriebs kein Kleber nachgefüllt werden, da ansonsten die Gefahr bestünde, dass nicht aufgeschmolzenes Klebermaterial in den Auftragsbereich kommt.Edge gluing devices of the aforementioned kind are generally known. For example, the DE 20 2006 000 747 U1 a portable gluing device comprising an applicator unit having a melting chamber and a bearing bush, the applicator unit being connected to a drive unit via at least one gear, and wherein the melting chamber has a dispensing cavity in which a rotatable applicator roller is located. The adhesive melted in the melting chamber passes into the dispensing cavity at this applicator, where it is conveyed upwards by the rotation of the applicator roll and corresponding elements on the wall of the cavity to that area where the edge material passes the applicator roll and is provided with adhesive (application area). The adhesive must be placed in the melting chamber before use, where it must be completely melted. This can take some time, which is undesirable. In addition, the volume of the melting chamber can not be increased further, because then this waiting time would increase even further. In addition, no adhesive can be refilled during operation, since otherwise there is a risk that not melted adhesive material comes in the order area.

Eine der Aufgaben der vorliegenden Erfindung besteht deshalb darin, die vorgenannte Kanten-Anleimvorrichtung so weiterzubilden, dass ihr die genannten Nachteile nicht mehr anhaften. Insbesondere soll die Wartezeit bis zur Nutzung verkürzt und darüber hinaus auch die Möglichkeit geschaffen werden, während des Betriebs Kleber nachzufüllen.Therefore, one of the objects of the present invention is to further develop the aforesaid edge banding device so that it no longer adheres to said disadvantages. In particular, the waiting time is to be shortened to use and also created the opportunity to refill adhesive during operation.

Dies Aufgabe wird bei der genannten Kanten-Anleimvorrichtung dadurch gelöst, dass die Schmelzkammer durch eine Zwischenwand in einen ersten und einen zweiten Kammerbereich aufgeteilt ist, wobei die beiden Kammerbereiche über zumindest eine Öffnung, vorzugsweise eine spaltförmige Öffnung, miteinander verbunden sind.This object is achieved in the aforementioned edgebanding device in that the melting chamber is divided by an intermediate wall into a first and a second chamber region, wherein the two chamber regions are connected to one another via at least one opening, preferably a gap-shaped opening.

Diese Maßnahmen haben den Vorteil, dass die Aufschmelzung des Schmelzklebers weiter verbessert wird. Zudem kann mehr Schmelzkleber-Grundmaterial in den Kleberbehälter eingegeben werden, der jedoch nicht vollständig aufgeschmolzen werden muss, um mit der Kanten-Anleimvorrichtung arbeiten zu können. Der der Förderkammer abgewandte Kammerbereich dient bei dieser Ausgestaltung sozusagen als Vorkammer, in die das Grundmaterial eingebracht wird, und von wo es dann allmählich in den anderen Kammerbereich gelangt.These measures have the advantage that the melting of the hot melt adhesive is further improved. In addition, more hot melt base material in the Admitted adhesive container, but does not have to be completely melted in order to work with the edgebander can. In this embodiment, the chamber region facing away from the delivery chamber serves, so to speak, as an antechamber, into which the base material is introduced, and from where it then gradually enters the other chamber region.

In einer bevorzugten Weiterbildung haben die beiden Kammerbereiche unterschiedliche Boden-Niveaus, wobei der der Förderkammer benachbarte Kammerbereich ein tieferes Boden-Niveau aufweist als der andere Kammerbereich.In a preferred development, the two chamber areas have different floor levels, wherein the chamber area adjacent to the conveyor chamber has a lower floor level than the other chamber area.

Diese Maßnahme hat den Vorteil, dass der Transport aus dem einen in den anderen Kammerbereich erleichtert wird, da Material auch durch den Einfluss der Schwerkraft gefördert wird.This measure has the advantage that the transport from one to the other chamber area is facilitated, since material is also promoted by the influence of gravity.

In einer bevorzugten Weiterbildung ist eine zweite Walze vorgesehen, die parallel zur Auftragswalze angeordnet ist und gegenläufig zu dieser angetrieben ist.In a preferred embodiment, a second roller is provided, which is arranged parallel to the applicator roll and is driven in opposite directions to this.

Das heißt mit anderen Worten, dass die beiden Walzen einen Spalt zwischen sich ausbilden, in den der Schmelzkleber durch die gegenläufige Bewegung der beiden Walzen "hineingesaugt" wird und in einem sich dahinter befindlichen Hohlraum nach oben in den gewünschten Bereich (Auftragsbereich) gedrückt wird.In other words, that the two rollers form a gap between them, in which the hot melt adhesive is "sucked in" by the opposite movement of the two rolls and in a cavity located behind it is pushed upwards into the desired area (application area).

Durch diese Maßnahme kann auf Wendeln im Bereich der Auftragswalze verzichtet werden. Zudem wird der Schmelzkleber deutlich besser nach oben gefördert, so dass eine Abkühlung kaum stattfindet.By this measure can be dispensed with coils in the field of applicator roll. In addition, the hotmelt adhesive is conveyed much better upwards, so that cooling hardly takes place.

Der Abstand der beiden Walzen zueinander ist vorzugsweise fest und wird so bemessen, dass die gegenläufige Bewegung zu einer Förderung des Klebers führt. Der Abstand liegt vorzugsweise zwischen 4 und 10 mm, vorzugsweise beträgt er 8 mm.The distance between the two rollers is preferably fixed and is dimensioned so that the opposite movement leads to a promotion of the adhesive. The distance is preferably between 4 and 10 mm, preferably 8 mm.

Die Umfangsgeschwindigkeit der beiden Walzen ist vorzugsweise gleich, was eine besonders gleichmäßige und homogene Förderung bewirkt. Besonders bevorzugt ist es, die Geschwindigkeit der beiden Walzen einstellbar auszuführen.The peripheral speed of the two rollers is preferably the same, which causes a particularly uniform and homogeneous promotion. It is particularly preferable to make the speed of the two rollers adjustable.

Die Einstellung der Geschwindigkeit hat den Vorteil, dass das Anbringen des Kantenmaterials auch in gebogenen Kantenbereichen sehr gut möglich ist, da durch die Reduzierung der Geschwindigkeit des Motors auch die Geschwindigkeit einer ebenfalls mit dem Motor gekoppelten Anpresswalze der Vorrichtung und damit die Relativgeschwindigkeit zwischen Werkstück und Vorrichtung verringert wird, so dass der Benutzer diesen Kantenbereich langsamer abfahren kann.The setting of the speed has the advantage that the attachment of the edge material is very well possible even in bent edge regions, as by reducing the speed of the motor and the speed of a likewise coupled to the motor pressure roller of the device and thus the relative speed between the workpiece and device is reduced, so that the user can lower this edge area slower.

Die beiden Walzen sind vorzugsweise an ihren beiden Enden, beispielsweise mittels Kugellagern, gelagert, was gegenüber der im Stand der Technik benutzten einseitigen Lagerung Vorteile hinsichtlich der Stabilität und der Größe der einzusetzenden Lager liefert.The two rollers are preferably mounted at their two ends, for example by means of ball bearings, which provides advantages over the one-sided bearing used in the prior art in terms of stability and the size of the bearing to be used.

In einer vorteilhaften Weiterbildung weisen die beiden Walzen an ihren oben liegenden Enden jeweils ein Zahnrad auf, wobei die beiden Zahnräder ineinander greifen und die Walzen gegenläufig antreiben.In an advantageous development, the two rollers each have a toothed wheel at their upper ends, the two toothed wheels meshing with one another and driving the rollers in opposite directions.

Diese Maßnahme hat den Vorteil, dass der gleichmäßige Antrieb der beiden Walzen auf einfache Art und Weise möglich ist. Durch Einstellen des Zahnverhältnisses der beiden Zahnräder kann die Umfangsgeschwindigkeit gewählt werden. Die beiden Walzen werden über einen gemeinsamen Motor angetrieben, wobei der Antrieb entweder über Riemen oder ebenfalls über Zahnräder erfolgt.This measure has the advantage that the uniform drive of the two rolls is possible in a simple manner. By adjusting the tooth ratio of the two gears, the peripheral speed can be selected. The two rollers are driven by a common motor, the drive is either via belt or also via gears.

Der Kleberbehälter ist in eine Förderkammer und eine Schmelzkammer aufgeteilt, wobei die beiden Kammern über eine Öffnung, vorzugsweise eine spaltförmige Öffnung, miteinander verbunden sind, und wobei die beiden Walzen in der Förderkammer angeordnet sind.The adhesive container is divided into a delivery chamber and a melting chamber, wherein the two chambers are connected to each other via an opening, preferably a gap-shaped opening, and wherein the two rollers are arranged in the delivery chamber.

Weiter bevorzugt weist die Förderkammer einen Hohlraum auf, der durch die beiden Walzen und eine Wand des Kleberbehälters begrenzt wird und der vorzugsweise spaltförmigen Öffnung gegenüberliegt, und wobei die Drehrichtung der beiden Walzen so gewählt ist, dass Schmelzkleber von der vorzugsweise spaltförmigen Öffnung in den Hohlraum gefördert wird.More preferably, the delivery chamber has a cavity, which is delimited by the two rollers and a wall of the adhesive container and the opposite preferably gap-shaped opening, and wherein the direction of rotation of the two rollers is selected so that hot melt promoted from the preferably gap-shaped opening into the cavity becomes.

Durch diese Maßnahme wird eine besonders gute Förderung des Schmelzklebers nach oben in den Auftragsbereich erreicht.By this measure, a particularly good promotion of hot melt adhesive is achieved up in the application area.

Die Heizelemente der Heizeinrichtung liegen vorzugsweise in der Zwischenwand, im Bereich der Förderkammer und bevorzugt unter der Schmelzkammer.The heating elements of the heating device are preferably in the intermediate wall, in the region of the delivery chamber and preferably under the melting chamber.

Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und der beiliegenden Zeichnung.Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

The edge banding device 10 is used to provide a band-shaped edge material 12 with an adhesive and to press it against an edge surface 13 of a plate-shaped workpiece 14. Since the present edge-gluing device 10 is intended for mobile use, it has two handles 16 at which the user can hold, guide and press the device against the edge surface 13.

Die Kanten-Anleimvorrichtung 10 besitzt eine Trägerplatte 18, an der die noch zu erläuternden Komponenten befestigt sind, und die zudem einen Bereich aufweist, der als Auflagefläche dient und im Betrieb auf dem Werkstück 14 aufliegt. Damit wird zumindest ein Teil des Gewichts der Anleimvorrichtung 10 aufgefangen, so dass der Nutzer sich auf die Führung und das Andrücken an die Kantenfläche 13 konzentrieren kann und nicht zusätzlich das Gewicht der Vorrichtung halten muss.The edge-gluing device 10 has a support plate 18, to which the components to be explained are still attached, and which also has a region which serves as a support surface and rests on the workpiece 14 during operation. Thus, at least a part of the weight of the glueing device 10 is collected, so that the user can concentrate on the guidance and the pressing against the edge surface 13 and does not have to additionally hold the weight of the device.

Die noch zu erläuternden Komponenten der Kanten-Anleimvorrichtung 10 sind aus Sicherheitsgründen mittels Abdeckungen 20 abgedeckt und daher in Fig. 6 nicht zu erkennen.The still to be explained components of the edge-gluing device 10 are covered by covers 20 for safety reasons and therefore in Fig. 6 not recognizable.

In Fig. 3, 4 und 5 ist die Trägerplatte 18 mit einigen angebrachten Komponenten dargestellt, wobei an dieser Stelle anzumerken ist, dass aus Übersichtlichkeitsgründen nicht alle Einzelteile dargestellt sind. Die Figuren beschränken sich auf jene Komponenten, die zum Verständnis der Erfindung erforderlich sind. Zu den nicht dargestellten Komponenten gehören beispielsweise Motor, Anpress- und Führungsrollen für das Kantenmaterial 12 sowie weitere elektrische bzw. elektronische Bauteile zur Versorgung von Heizelementen und Motor mit elektrischer Energie.In Fig. 3, 4 and 5 the support plate 18 is shown with some attached components, it being noted at this point that not all individual parts are shown for clarity. The figures are limited to those components which are necessary for understanding the invention. The components not shown include, for example, motor, pressure and guide rollers for the edge material 12 and other electrical or electronic components for supplying heating elements and motor with electrical energy.

Wie sich aus Fig. 3 bis 5 ergibt, ist an der Unterseite der Trägerplatte 18 ein Kleberbehälter 30 angebracht, dessen Aufbau mit Bezug auf die Fig. 1 und 2 später näher erläutert werden wird.As it turned out Fig. 3 to 5 shows, on the underside of the support plate 18, an adhesive container 30 is mounted, whose structure with respect to the Fig. 1 and 2 will be explained in more detail later.

In den Kleberbehälter 30 ragen zwei Walzen 40, 50 hinein, die an ihrem oberen Ende mit Zahnrädern 42 bzw. 52 versehen sind. Deutlich zu erkennen ist in Fig. 3 und 5, dass die beiden Zahnräder 42, 52 ineinander greifen, so dass die Drehbewegung einer Walze auf die andere Walze übertragen wird. Vorzugsweise besitzen beide Zahnräder 42, 52 die gleiche Anzahl von Zähnen, so dass ein Übersetzungsverhältnis von 1:1 erreicht wird. Der obere Teil der beiden Walzen 40, 50 ist mit Abdeckungen 22, 24 abgedeckt, wobei innerhalb dieser Abdeckungen ein Lager 44, wie in Fig. 4 zu sehen ist, vorgesehen ist. Ein weiteres Lager 44 befindet sich am unteren Ende der Walzen 40, 50 und ist im Boden des Kleberbehälters 30 vorgesehen.In the adhesive container 30 protrude two rollers 40, 50, which are provided at their upper end with gears 42 and 52, respectively. Clearly visible in FIGS. 3 and 5 in that the two toothed wheels 42, 52 intermesh so that the rotational movement of one roller is transferred to the other roller. Preferably, both gears 42, 52 have the same number of teeth, so that a gear ratio of 1: 1 is achieved. The upper part of the two rollers 40, 50 is covered with covers 22, 24, wherein within these covers a bearing 44, as in Fig. 4 is to be seen, is provided. Another bearing 44 is located at the lower end of the rollers 40, 50 and is provided in the bottom of the adhesive container 30.

Wie bereits zuvor angedeutet, umfasst die Kanten-Anleimvorrichtung 10 einen Motor, der eine der beiden Walzen 40, 50 antreibt, wobei als Antrieb üblicherweise ein Riemen zum Einsatz kommt. Bevorzugt ist dem Motor eine Steuerungseinrichtung zugeordnet, die es dem Anwender erlaubt, die Geschwindigkeit des Motors einzustellen, so dass er für die Bearbeitung kurviger Kantenabschnitte mit einer geringeren Relativgeschwindigkeit zwischen Werkstück und Anleimvorrichtung arbeiten kann. Dies liegt daran, dass der Motor nicht nur die beiden Walzen 40, 50 antreibt, sondern auch eine Anpresswalze, die an das Werkstück angedrückt wird und damit für eine Bewegung der Anleimvorrichtung gegenüber dem Werkstück sorgt. Durch die feste Kopplung der beiden Walzen 40, 50 und der Anpresswalze mit dem Motor (bspw. über ein Getriebe) wird gewährleistet, dass immer eine der Vorschubgeschwindigkeit angepasste Menge an Kleber zum Kantenmaterial transportiert wird.As already indicated above, the edge-gluing device 10 comprises a motor which drives one of the two rollers 40, 50, wherein a belt is usually used as the drive. Preferably, the motor is associated with a control device that allows the user to adjust the speed of the motor so that it can work for the processing of curvy edge portions with a lower relative speed between the workpiece and the glueing device. This is because the motor not only drives the two rollers 40, 50, but also a pressure roller, which is pressed against the workpiece and thus ensures a movement of the glueing device relative to the workpiece. By the fixed coupling of the two rollers 40, 50 and the pressure roller with the motor (for example. Via a gearbox) ensures that always one of the feed rate adapted amount of adhesive is transported to the edge material.

Wie ebenfalls bereits zuvor erläutert, besitzt die Trägerplatte 18 einen Bereich, der als Auflage- oder Abstützfläche verwendet wird, um die Vorrichtung 10 auf dem Werkstück 14 abzustützen. Diese Auflagefläche ist in Fig. 4 mit dem Bezugszeichen 26 gekennzeichnet.As also previously explained, the support plate 18 has a portion which is used as a support or support surface to support the device 10 on the workpiece 14. This bearing surface is in Fig. 4 designated by the reference numeral 26.

Schließlich ist in Fig. 3 noch eine Führung 22 zu erkennen, die senkrecht von der Trägerplatte 18 nach oben verläuft und dazu dient, das Kantenmaterial 12 gezielt an einer der beiden Walzen 40, 50 vorbeizuführen, im vorliegenden Ausführungsbeispiel an der Walze 40, die als Auftragswalze für den Schmelzkleber dient.Finally, in Fig. 3 to recognize a guide 22 which extends perpendicularly from the support plate 18 upwards and serves to pass the edge material 12 targeted to one of the two rollers 40, 50, in the present embodiment of the roller 40, which serves as an applicator roll for the hot melt adhesive.

Der Aufbau des Kleberbehälters 30 wird nun mit Bezug auf die Fig. 1 und 2 näher erläutert.The structure of the adhesive container 30 will now be described with reference to FIGS Fig. 1 and 2 explained in more detail.

Der Kleberbehälter 30 besitzt eine Quaderform, die durch eine Außenwand bzw. Behälterwand 32 definiert wird. Die Behälterwand 32 umgibt zusammen mit einer Bodenfläche einen Innenraum 34.The adhesive container 30 has a cuboid shape, which is defined by an outer wall or container wall 32. The container wall 32 surrounds an interior space 34 together with a bottom surface.

Der Innenraum 34 ist in unterschiedliche Bereiche unterteilt, nämlich eine Förderkammer 60, eine Schmelzkammer 62 und eine Vorkammer 64. Die Förderkammer 60 besitzt eine Form, die zur Aufnahme der beiden Walzen 40, 50 ausgelegt ist, wobei zwischen den beiden Walzen 40, 50 ein Spalt verbleibt.The interior space 34 is subdivided into different areas, namely a delivery chamber 60, a melting chamber 62 and an antechamber 64. The delivery chamber 60 has a shape designed to receive the two rolls 40, 50, wherein between the two rolls 40, 50 a Gap remains.

Die Förderkammer 60 steht über einen Spalt 70 in Verbindung mit der Schmelzkammer 62. Die Breite des Spalts 70 entspricht dabei etwa der Spaltbreite zwischen den beiden Walzen 40, 50. In Fig. 2c ist noch deutlich zu erkennen, dass die Förderkammer 60 einen Hohlraum 80 aufweist, der dem Spalt 70 gegenüberliegt und durch die beiden Walzen 40, 50 begrenzt wird. In diesem Hohlraum 80 wird flüssiger Schmelzkleber nach oben in den Auftragsbereich transportiert, was später noch erläutert werden wird.The delivery chamber 60 communicates with the melting chamber 62 via a gap 70. The width of the gap 70 corresponds approximately to the gap width between the two rollers 40, 50 Fig. 2c is still clearly seen that the delivery chamber 60 has a cavity 80 which is opposite to the gap 70 and is limited by the two rollers 40, 50. In this cavity 80 liquid hot melt adhesive is transported up into the application area, which will be explained later.

Die Schmelzkammer 62 ist von der Vorkammer 64 durch eine Zwischenwand 76 getrennt, die sich jedoch nicht über die gesamte Breite des Innenraums 34 erstreckt, so dass seitlich spaltförmige Öffnungen 77 verbleiben, die eine Verbindung zwischen der Schmelzkammer 62 und der Vorkammer 64 schaffen. Es versteht sich jedoch, dass die Öffnungen auch andere Formen aufweisen können und nicht notwendigerweise spaltförmig sein müssen.The melting chamber 62 is separated from the pre-chamber 64 by an intermediate wall 76, which does not extend over the entire width of the inner space 34, so that laterally gap-shaped openings 77 remain, which provide a connection between the melting chamber 62 and the prechamber 64. However, it will be understood that the apertures may be of other shapes and need not necessarily be slit-shaped.

Aus der Fig. 2a ist ersichtlich, dass der Boden der Vorkammer 64 höher liegt als der Boden der Schmelzkammer 62 sowie der Förderkammer 60, die auf gleichem Niveau liegen. Darüber hinaus ist aus Fig. 2a zu erkennen, dass die Zwischenwand 76 eine Buchse 78 enthält, die zur Unterseite des Kleberbehälters 30 offen ist und zur Aufnahme eines Heizelements in Form einer Heizpatrone dient. Weitere Bohrungen bzw. Buchsen zur Aufnahme von Heizelementen sind im Bereich der Förderkammer 60 sowie im unteren Bereich des Kleberbehälters 30 vorgesehen und mit dem Bezugszeichen 86 gekennzeichnet. Durch das Anbringen mehrerer Heizelemente ist eine besonders gute und gleichmäßige Erwärmung des zunächst festen Schmelzklebergrundmaterials möglich.From the Fig. 2a It can be seen that the bottom of the pre-chamber 64 is higher than the bottom of the melting chamber 62 and the delivery chamber 60, which are at the same level. In addition, is off Fig. 2a it can be seen that the intermediate wall 76 includes a bushing 78, which is open to the underside of the adhesive container 30 and serves to receive a heating element in the form of a heating cartridge. Further holes or sockets for receiving heating elements are provided in the region of the delivery chamber 60 and in the lower region of the adhesive container 30 and designated by the reference numeral 86. By attaching several heating elements, a particularly good and uniform heating of the initially solid hotmelt adhesive base material is possible.

Die Funktionsweise der Kanten-Anleimvorrichtung 10, insbesondere im Hinblick auf das Aufschmelzen und Fördern des Schmelzklebers, ist nun wie folgt:The operation of the edge-gluing device 10, in particular with regard to the melting and conveying of the hot-melt adhesive, is now as follows:

Vor dem Betrieb wird in die Vorkammer 64 granulatartiges Schmelzklebermaterial hineingegeben. Durch Aktivieren der Heizelemente wird das Schmelzklebergranulat erwärmt und wird bei Erreichen einer vorgegebenen Temperatur von etwas über 100° flüssig. Der flüssige Schmelzkleber sammelt sich in der Schmelzkammer 62, die tiefer liegt als die Vorkammer 64. Soll nun Schmelzkleber in den Auftragsbereich transportiert werden, werden die beiden Walzen 40, 50 angetrieben und führen durch ihre gegenläufige Drehung flüssigen Schmelzkleber aus der Schmelzkammer 62 in die Förderkammer 60 durch den Spalt 70. Durch die Drehung der beiden Walzen 40, 50 gelangt der flüssige Schmelzkleber in den Hohlraum 80, wo er durch den weiter nachgeförderten Schmelzkleber nach oben in den Auftragsbereich gefördert wird.Prior to operation, 64 granular hot melt adhesive material is added to the prechamber 64. By activating the heating elements, the hot melt granulate is heated and becomes liquid when a predetermined temperature of just over 100 ° C is reached. The liquid hot melt adhesive collects in the melting chamber 62, which is lower than the prechamber 64. If now hot melt adhesive are transported in the order area, the two rollers 40, 50 are driven and lead by their opposite rotation liquid melt adhesive from the melting chamber 62 into the delivery chamber 60 through the gap 70. By the rotation of the two rollers 40, 50 passes the liquid hot melt adhesive into the cavity 80, where it is conveyed by the further nachgeförderten hot melt adhesive in the application area.

Gleichzeitig gelangt Schmelzklebermaterial aus der Vorkammer 64 in die Schmelzkammer 62, wo es vollständig aufgeschmolzen wird.At the same time hot melt adhesive material passes from the antechamber 64 into the melting chamber 62, where it is completely melted.

Durch das Bereitstellen einer Vorkammer 64 ist es möglich, auch im Betrieb Granulat nachzufüllen, ohne dass dadurch festes Material in den Auftragsbereich käme. Der Betrieb muss folglich nicht unterbrochen werden - wie dies im Stand der Technik der Fall ist -, wenn der Kleberbehälter 30 leer wird, um das nachgefüllte Material erst wieder vollständig aufschmelzen zu können.By providing an antechamber 64, it is possible to refill granules even during operation, without this resulting in solid material in the application area. The operation must therefore not be interrupted - as is the case in the prior art - when the adhesive container 30 is empty in order to melt the refilled material only completely again.

Die Funktionsweise der Auftragswalze 40 im Auftragsbereich sowie die Führung und das Anpressen des Kantenmaterials 12 erfolgt dann wie bei den bekannten Vorrichtungen, so dass darauf nicht weiter eingegangen werden muss.The operation of the applicator roll 40 in the order area as well as the guidance and the pressing of the edge material 12 then takes place as in the known devices, so that it need not be discussed further.

Insgesamt zeigt sich, dass die erfindungsgemäße Kanten-Anleimvorrichtung 10 durch die beiden Walzen 40, 50 eine äußerst gute und schnelle Förderung des flüssigen Schmelzklebers aus der Schmelzkammer 62 in den Austragsbereich ermöglicht. Durch die schnelle und effektive Förderung des Schmelzklebers kann in der Schmelzkammer 62 mit niedrigeren Temperaturen gearbeitet werden, da die Abkühlung des Schmelzklebers bei der Förderung in den Auftragsbereich nicht so stark ist wie bei den bekannten Vorrichtungen. Ferner kann - wie bereits erwähnt - durch die Zweiteilung des Innenraums 34 in eine Vorkammer und eine Schmelzkammer auch im Betrieb Schmelzklebermaterial nachgefüllt werden, ohne danach die vollständige Aufschmelzung dieses Materials abwarten zu müssen. Zudem ermöglicht diese Zweiteilung volumengrößere Kleberbehälter 30, ohne den Nachteil einer langen Wartezeit bis zur vollständigen Aufschmelzung des Inhalts des Kleberbehälters 30, wie dies bei den bekannten Vorrichtungen notwendig ist. Vielmehr genügt es, dass ausreichend flüssiger Schmelzkleber in der Schmelzkammer 62 vorhanden ist, um mit dem Betrieb zu starten.Overall, it is shown that the edge-gluing device 10 according to the invention by the two rollers 40, 50 allows a very good and fast promotion of the liquid hot melt adhesive from the melting chamber 62 in the discharge. Due to the rapid and effective promotion of the hot melt adhesive can be used in the melting chamber 62 at lower temperatures, since the cooling of the hot melt adhesive in the promotion in the order area is not as strong as in the known devices. Furthermore, as already mentioned, hot melt adhesive material can be replenished even during operation by dividing the interior space 34 into an antechamber and a melting chamber, without having to wait until this material completely melts. In addition, this division allows volume larger adhesive container 30, without the disadvantage of a long wait until the complete melting of the contents of the adhesive container 30, as is necessary in the known devices. Rather, it is sufficient that sufficient liquid hot melt adhesive is present in the melting chamber 62 to start with the operation.
