Abstract

The glueing device is attached so that it contacts the edge of an article being processed, in partic. articles of wood. At least one of the surfaces to which adhesive is to be applied is precoated with a heat sensitive adhesive before the process is completed. Then the heat sensitive adhesive layer (8) is heated by an ultrasonic system after the glueing device (6) has been brought into contact with the workpiece (3). The glueing device (6) can then be rigidly connected to the workpiece (3) after the heat- sensitive adhesive has solidified.

Description

Verfahren und Vorrichtung zum Ankleben eines Umleimers an die Kante eines Werkstücks aus Holz oder dergl..Method and device for gluing an edge band to the edge a workpiece made of wood or the like.

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Ankleben eines Umleimers an die Kante eines Werkstücks aus Holz oder der,, wobei mindestens eine der zu verklebenden Flächen mit Schmelzkleber vorbe -schichtet ist0 Zum Schutz der Kanten von Plattenförmigen Werkstücken aus Holz oder ähnlichen Werkstoffen, wie zOBo Spanplatten, werden an diese Kanten sogenannte Umleimer aus Holzfurnier, dünne Folienbänder aus thermoplastischen oder duroplastischen Werkstoffen, Aluminium uswO angeklebt, Es ist bei Kantenanleimmaschinen bekannt, eine Fläche des Umleimers mit einer Schicht aus Schmelzkleber vorzubeschichten, wobei dann diese Schmelzkleberschicht vor dem Zusammenführen des Umleimers mit dem plattenförmigen werkstück durch Heißluft so erwärmt wird, daß sie schmilzt und daß sich nach dem Anpressen des Umleimers an die Werkstückkante der Umleimer nach dem Erstarren des Schmelzklebers mit dem Werkstück fest verbindet.The present invention relates to a method and an apparatus for gluing an edge band to the edge of a workpiece made of wood or the ,, being at least one of the surfaces to be bonded is pre-coated with hot-melt adhesive0 To protect the edges of panel-shaped workpieces made of wood or similar materials, like zOBo chipboard, so-called edge strips made of wood veneer are attached to these edges, thin film strips made of thermoplastic or thermosetting materials, aluminum etc. Glued on, it is known with edge banding machines, a surface of the edge band precoat with a layer of hot melt adhesive, then this hot melt adhesive layer before the edge band is brought together with the plate-shaped workpiece by hot air is heated so that it melts and that after pressing the edge band to the workpiece edge of the edge band after the hot melt adhesive has solidified with the Workpiece firmly connects.

0 Die Heißluft weist dabei eine Temperatur von ca 4ob 0 auf und erhitzt beim Austreten aus der Düse nicht nur den Schmelzkleber, sondern auch die umgebenden Teile der HantenanleimmaschineO Es sind daher besondere Sicherheitsmaßnahmen notwendig, um zu vermeiden, daß der Bedienungsmann mit der Heißluft oder den erhitzten Teilen in Berührung kommt, Dünne Umleimer, insbesondere aus thermoplastischen Werkstoffen, wie zOBo PVC, werden durch die Heißluft ebenfalls so stark erwärmt, daß sie sich verwerfen, so daß keine einwandfreie Verleimung mit dem Werkstück möglich ist. Zum einwandfreien Anpressen des Umleimers sind außerdem mehrere Druckrollen nötig, die den Umleimer gegen das Werkstück drücken, solange der Schmelzkleber noch nicht ganz erstarrt ist. Diese Einrichtung bedingt eine Ver -größerung der Baulänge der KantenanleimmaschineO Bedingt durch die schlechte Wärmeleitfähigkeit des Schmelzklebers ist zum Aufheizen der Schmelzkleberschicht eine längere Anwärmzeit notwendig, die sich auf den Arbeitsablauf störend auswirkt und während des Betriebs die Fördergeschwindigkeit des Werkstücks begrenzt, Weiterhin kann es vorkommen, daß der bereits flüssige Schmelzkleber des bereitgestellten Umleimers die Führungsrollen und andere Teile der Kantenanleimmaschine verschmutzt, Aufgabe der vorliegenden Erfindung ist daher ein Verfahren und eine Vorrichtung, bei der die Erwärmung des Schmelzklebers unmittelbar in der Kleberfuge zwischen dem bereits mit dem Werkstück zusammengeführten Umleimer erfolgt0 Diese Aufgabe wird gemäß der vorliegenden Erf- ,rJ dadurch gelöst, daß die Schmelzkleberschicht nach dem Zusammenführen des Umleimers mit dem Werkstück mittels Ultraschall so erwärmt wird, daß sich der Umleimer mit dem Werkstück nach dem anschließenden Erstarren der Schmelzkleberschicht fest verbindete Dadurch werden die oben genannten Nachteile sicher vermieden, es ist keine Aufwärmzeit notwendig und der Schmelzkleber des noch nicht mit dem Werkstück zusammengeführten Umleimers wird nicht erwärmt und kann somit auch nicht die Teile der Kantenanleimmaschine verschmutzen0 Da das Ultraschallwerkzeug im Betrieb unmittelbar gegen den bereits mit der Werkstückkante zusammengeführten Umleimer gepreßt wird, wird der Umleimer durch die mechanischen Schwingungen des Ultraschallwerkzeuges auf die Werkstückkante aufgehämmert, so daß sich Druckwalzen zum anschließenden Andrücken des Umleimers erübrigen. Der Schmelzkleber wird nur im Bereich des Ultraschallwerkzeuges erwärmt und erstarrt anschließend sofort, wobei der Umleimer so fest mit der Werkstückkante verbunden wird, daß im Anschluß an das Ultraschallwerkzeug sofort weitere Bearbeitungseinheiten, wie z,B, Fräser, angeordnet werden können, Dies führt zu einer erheblichen Verkürz;ung der gesamten Baulänge der Kantenanle immaschine.0 The hot air has a temperature of about 40 0 and is heated when exiting the nozzle, not only the hot-melt adhesive, but also the surrounding ones Parts of the hand-gluing machine O Special safety measures are therefore necessary to avoid the operator with the hot air or the comes into contact with heated parts, thin edge band, especially made of thermoplastic Materials such as zOBo PVC are also heated so much by the hot air that that they warp, so that no perfect gluing with the workpiece is possible is. There are also several pressure rollers to ensure that the edge is pressed properly necessary to press the edge band against the workpiece while the hotmelt adhesive is still working is not completely frozen. This facility requires an increase in the overall length of the edge banding machine O Due to the poor thermal conductivity of the hot melt adhesive a longer warm-up time is necessary to heat up the hotmelt adhesive layer has a disruptive effect on the workflow and the conveyor speed during operation of the workpiece, it can also happen that the already liquid hot melt adhesive of the edge band provided, the guide rollers and other parts of the edge banding machine dirty, the object of the present invention is therefore a method and a Device in which the hot melt adhesive is heated directly in the adhesive joint between the edge band that has already been brought together with the workpiece, this takes place The object is achieved according to the present invention in that the hotmelt adhesive layer after the edge band has been brought together with the workpiece, it is heated in this way by means of ultrasound becomes that the edge band with the workpiece after the subsequent solidification the hotmelt adhesive layer firmly connected. This eliminates the disadvantages mentioned above safely avoided, no warm-up time is necessary and the hot-melt adhesive of The edge band that has not yet been joined to the workpiece is not heated and can therefore not contaminate the parts of the edge banding machine0 Because the ultrasonic tool in operation directly against the one already merged with the workpiece edge Edge band is pressed, the edge band is pressed by the mechanical vibrations of the Ultrasonic tool hammered on the edge of the workpiece, so that pressure rollers for the subsequent pressing on of the edge band. The hot melt glue will only heated in the area of the ultrasonic tool and then solidified immediately, wherein the edge band is so firmly connected to the workpiece edge that after the Ultrasonic tool immediately arranged further processing units, such as, for example, milling cutters This leads to a considerable reduction in the overall length the edgebanding machine.

Bei einer weiteren vorteilhaften Ausführungsform der Brfindung kann die Ultraschalleinrichtung mit einer Heißluftdüse kombiniert werden, deren Heißluftstrom den Schmelzkleber erhitzt, bevor der Umleimer mit dem Werkstück zusammengeführt wird, Damit ist eine weitere Steigerung der Fördergeschwindigkeit des Werkstücks möglich, so daß gegenüber den bekannten Verfahren eine wesentliche Verbesserung der Wirtschaftlichkeit eintritt, Im folgenden sind Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben.In a further advantageous embodiment of the invention can the ultrasonic device can be combined with a hot air nozzle, whose hot air flow the hot melt adhesive is heated before the edge band is merged with the workpiece This is a further increase in the conveying speed of the workpiece possible, so that a substantial improvement over the known processes The following are exemplary embodiments of the invention described in more detail with reference to the drawings.
