Description

Die Erfindung betrifft eine Vorrichtung gemäß Oberbegriff von Anspruch 1.The invention relates to a device according to the preamble of claim 1.

Aus der DE-OS 27 31 799 ist eine Schmelz- und Auftragsvorrichtung der eingangs genannten Art in Verbindung mit einer Kantenanleimmaschine bekannt, bei der die Schmelzwand einstückig mit der Auftragsvorrichtung verbunden ist. Von Heizelementen im Düsenkörper der Auftragsvorrichtung gelangt die Wärme an die Schmelzwand, die mit konzentrischen Ringnuten versehen ist und von der der geschmolzene Schmelzkleber durch einseitig angeordnete Austrittsöffnungen der Auftragsvorrichtung zugeführt wird.From DE-OS 27 31 799 a melting and application device of the type mentioned in connection with an edge banding machine is known in which the melting wall is integrally connected to the application device. From heating elements in the nozzle body of the application device, the heat reaches the melting wall, which is provided with concentric annular grooves and from which the melted hot melt adhesive is supplied to the application device through outlet openings arranged on one side.

Diese Anordnung kann jedoch dazu führen, daß der geschmolzene Schmelzkleber nicht immer gleichmäßig und in maximal möglicher Abschmelzmenge der Auftragsvorrichtung zugeführt wird. Auch die sollte\Schmelztemperatur den verschiedenen Schmelzklebersorten angepaßt werden, während für die Auftragsvorrichtung eine gleichbleibende Temperatur erwünscht ist, die sich im allgemeinen von der Schmelztemperatur unterscheidet.However, this arrangement can lead to the fact that the molten hot melt adhesive is not always fed uniformly and in the maximum possible amount of melt to the application device. The should \ melting temperature different melt adhesive locations are adjusted, while for the application device a constant temperature is desired, the generally differs from the melting temperature.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Schmelz-und Auftragsvorrichtung für Schmelzkleber zu schaffen, deren Temperaturen auf verschiedene Schmelzklebersorten und auf verschiedene Arbeitsbedingungen optimal einstellbar ist und mit der eine gleichmäßige und möglichst hohe Förderung des geschmolzenen Schmelzklebers und damit eine möglichst hohe Arbeitsgeschwindigkeit erreichbar ist.The invention is therefore based on the object of providing a melting and application device for hot melt adhesives, the temperatures of which can be optimally adjusted to different types of hot melt adhesive and to different working conditions and with which a uniform and as high a possible conveyance of the melted hot melt adhesive and thus the highest possible working speed can be achieved .

Diese Aufgabe wird dadurch gelöst, daß zwischen Schmelzkammer und Auftragsvorrichtung ein mit der Schmelzwand versehener Schmelzeinsatz angeordnet ist.This object is achieved in that a melting insert provided with the melting wall is arranged between the melting chamber and the application device.

Damit ist es möglich, die Auftragsvorrichtung u. die Schmelzwand mit verschiedenen Temperaturen zu beheizen, so daß eine optimale Anpassung an die gegebenen Arbeitsbedingungen möglich ist. Wird für den Schmelzeinsatz erfindungsgemäß ein Werkstoff mit hoher Wärmeleitfähigkeit, wie z.B. eine Leichtmetall-Legierung verwendet, dann wird die Wärme der Heizvorrichtung besonders schnell dem Schmelzkleber mitgeteilt. Dies wirkt sich besonders bei der Inbetriebnahme der Kantenanleimmaschine günstig aus, da die Aufheizzeit für den Schmelzeinsatz bis zum Start der Kantenanleimmaschine sehr niedrig ist. Andererseits ist es möglich, die Auftragsvorrichtung aus einem metallischen Werkstoff hoher Festigkeit herzustellen und damit eine hohe Lebensdauer dieser Auftragsvorrichtung zu erzielen. Da diese metallischen Werkstoffe hoher Festigkeit jedoch schlechte Wärmeleiter sind, würde ihre Verwendung als Schmelzeinsatz die Zeiten zum Aufheizen und Abkühlen wesentlich erhöhen. Die Verwendung von verschiedenen Werkstoffen für die Auftragsvorrichtung und für den Schmelzeinsatz entspricht daher in vorteilhafter Weise sowohl den mechanischen als auch den wärmetechnischen Forderungen der gesamten Vorrichtung.This makes it possible to u. to heat the melting wall with different temperatures so that an optimal adaptation to the given working conditions is possible. If a material with high thermal conductivity, such as e.g. If a light metal alloy is used, the heat of the heating device is communicated to the hot melt adhesive particularly quickly. This has a particularly favorable effect when commissioning the edge banding machine, since the heating-up time for the melt application is very short until the edge banding machine starts. On the other hand, it is possible to manufacture the application device from a metallic material of high strength and thus to achieve a long service life for this application device. However, since these high strength metallic materials are poor heat conductors, their use as a melt insert would significantly increase the times for heating and cooling. The use of different materials for the application device and for the melt insert therefore advantageously corresponds to both the mechanical and the thermal requirements of the entire device.

Durch die erfindungsgemäße Anordnung von Schmelzzapfen an der Schmelzwand, in die sich Kanäle erstrecken, die die Schmelzkammer mit einer zwischen SchmelzeLnsatz und Auftragsvorrichtung angeordneten Vorratskammer verbinden, ergibt sich der Vorteil, daß der Schmelzkleber gleichmäßig abgeschmolzen und zentrisch der Vorratskammer zugeführt wird. Dadurch wird die Leistungsfähigkeit der Kantenanleimmaschine erheblich verbessert.The arrangement according to the invention of melting pins on the melting wall, into which channels extend which connect the melting chamber with a storage chamber arranged between the melt insert and the application device, has the advantage that the hot melt adhesive is melted off evenly and is fed centrally to the storage chamber. This significantly improves the performance of the edge banding machine.

Durch die erfindungsgemäße Anordnung eines Zuführungskanals für den Schmelzkleber von der Vorratskammer zur Auftragsvorrichtung, der in den unteren Bereich der Vorratskammer münde'. ist gewährleistet, daß sich im unteren Bereich der Vorratskammer keine ruhende Schmelzkleberschicht bildet, sondern daß ein kontinuierlicher Fluß des geschmolzenen Schmelzklebers zur Auftragsvorrichtung stattfindet. Da auch der Temperaturfühler zur Steuerung der Heizvorrichtung für den Schmelzeinsatz im unteren Bereich der Vorratskammer angeordnet ist, ist eine sichere Temperaturregelung für den Schmelzeinsatz gewährleistet. Dieser Temperaturfühler wird jedoch nicht nur von der Temperatur des geschmolzenen Schmelzklebers, sondern auch von der Temperatur des Schmelzeinsatzes bzw. der Schmelzwand beeinflußt. Es bildet sich somit aus diesen beiden Temperaturwerten selbsttätideine optimale Regelkennlinie für die Abschmelztemperatur der Schmelzwand.Due to the inventive arrangement of a supply duct for the hot-melt adhesive from the storage chamber to the application device, which opens into the lower region of the storage chamber '. it is ensured that no dormant hot melt adhesive layer forms in the lower area of the storage chamber, but that there is a continuous flow of the molten hot melt adhesive to the applicator. Since the temperature sensor for controlling the heating device for the melt insert is also arranged in the lower region of the storage chamber, safe temperature control for the melt insert is ensured. This temperature sensor is not only influenced by the temperature of the melted hot melt adhesive, but also by the temperature of the melt insert or the melt wall. An optimal control characteristic curve for the melting temperature of the melting wall is thus automatically formed from these two temperature values.

Im folgenden ist ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben.An exemplary embodiment of the invention is described in more detail below with reference to the drawings.

  • Fig. 3 Schnitt nach Linie III - III in Fig. 1.

  • Fig. 1 melting and application device, front view.
  • 2 section along line II - II in Fig. 1st
  • 3 section along line III - III in Fig. 1st
  • Fig. 4 melter, rear view.

Die Fig. 1 zeigt eine Auftragsvorrichtung 1, wie sie zum Auftragen von flüssigem Schmelzkleber bei einer nicht dargestellten Kantenanleimmaschine auf die seitliche Schmalfläche eines plattenförmigen Werkstückes verwendet wird.1 shows an application device 1 as it is used for applying liquid hot-melt adhesive in an edge banding machine, not shown, to the narrow side surface of a plate-shaped workpiece.

Dazu ist ein keilförmiger Düsenkörper 2 mit Auftragsbohrungen 3 versehen, die in einen Zuführkanal 4 münden (siehe auch Fig.2). Der Auftrag des Schmelzklebers wird in bekannter Weise durch einen Drehschieber 5 gesteuert, die Heizung des Düsenkörpers 2 erfolgt durch ein Heizelement 6, dessen Temperatur durch einen Temperaturfühler 7 gesteuert wird.For this purpose, a wedge-shaped nozzle body 2 is provided with application bores 3, which open into a feed channel 4 (see also FIG. 2). The application of the hot melt adhesive is controlled in a known manner by means of a rotary slide valve 5, the nozzle body 2 is heated by a heating element 6, the temperature of which is controlled by a temperature sensor 7.

Mit der Auftragsvorrichtung 1 ist eine Schmelzvorrichtung 8 verbunden (Fig. 2) die im wesentlichen eine Schmelzkammer 9 und einen Schmelzeinsatz 10 aufweist. Dieser schließt die Schmelzkammer 9 mit seiner Schmelzwand 11 ab, gegen die mittels eines Förderkolbens 12 die Schmelzklebereinheit 13 gedrückt wird.A melting device 8 is connected to the application device 1 (FIG. 2), which essentially has a melting chamber 9 and a melting insert 10. This closes the melting chamber 9 with its melting wall 11, against which the hot-melt adhesive unit 13 is pressed by means of a delivery piston 12.

Der zylindrische Schmelzeinsatz 10 ist mit Schrauben 14 am Düsenkörper 2 der Auftragsvorrichtung 1 befestigt (Fig.l und 3). Die zur Schmelzkammer 9 gerichtete Schmelzwand 11 wird durch Schmelzzapfen 15 gebildet, (siehe auch Fig. 4), die gleichmäßig und symmetrisch über den Querschnitt des Schmelzeinsatzes 10 verteilt sind. Auf der entgegengesetzten Seite ist der Schmelzeinsatz 10 so konkav gewölbt, daß eine Vorratskammer 16 entsteht. Diese Vorratskammer 16 ist in der Mitte durch senkrechte Stege 17 unterteilt, die am oberen Rand der Vorratskammer 16 beginnen und in einem bestimmten Abstand vom unteren Rand der Vorratskammer enden. In diesem unteren Bereich der Vorratskammer 16 ist ein Vorsprung 18 des Schmelzeinsatzes 10 angeordnet, mit dem ein Temperaturfühler 19 leitend verbunden ist. Dieser Temperaturfühler 19 beeinflußt Heizelemente 20, die zur Beheizung des Schmelzeinsatzes 10 dienen. Da dieser aus einer Leichtmetallegierung hergestellt ist, wird die Wärme der Heizelemente 20 rasch an die Schmelzwand 11 weitergeleitet.The cylindrical melting insert 10 is fastened with screws 14 to the nozzle body 2 of the application device 1 (FIGS. 1 and 3). The melting wall 11 facing the melting chamber 9 is formed by melting pins 15 (see also FIG. 4), which are distributed uniformly and symmetrically over the cross section of the melting insert 10. On the opposite side, the melting insert 10 is curved so concavely that a storage chamber 16 is formed. This storage chamber 16 is divided in the middle by vertical webs 17 which begin at the upper edge of the storage chamber 16 and end at a certain distance from the lower edge of the storage chamber. In this lower region of the storage chamber 16 there is a projection 18 of the melting insert 10, to which a temperature sensor 19 is conductively connected. This temperature sensor 19 influences heating elements 20, which are used to heat the melting insert 10. Since this is made of a light metal alloy, the heat of the heating elements 20 is quickly passed on to the melting wall 11.

Der Schmelzeinsatz 10 wird, von der Vorratskammer 16 ausgehend, von senkrechten Kanälen 21 durchdrungen, die sich teilweise in die Schmelzzapfen 15 hinein erstrecken. Sie verbinden damit die Schmelzkammer 9 mit der Vorratskammer 16.Starting from the storage chamber 16, the melting insert 10 is penetrated by vertical channels 21, which partially extend into the melting pins 15. They thus connect the melting chamber 9 to the storage chamber 16.

BeimBetrieb der Schmelz-und Auftragsvorrichtung wird der an der erhitzen Schmelzwand 11 anliegende Teil der Schweilzklebereinheit 13 geschmolzen und der geschmolzene Schmelzkleber unter Wirkung des Förderkolbens 12 durch die Kanäle 21 in die Vorratskammer 16 gedrückt. Von dort gelangt der Schmelzkleber von unten zwischen die Stege 17 in den Zuführkanal 4 und weiter über die Auftragsbohrungen 3 auf die seitliche Schmalfläche des Werkstückes.During operation of the melting and application device, the part of the hot-melt adhesive unit 13 which is in contact with the heated melting wall 11 is melted and the melted hot-melt adhesive is pressed through the channels 21 into the storage chamber 16 under the action of the delivery piston 12. From there, the hot melt adhesive gets between the bottom the webs 17 into the feed channel 4 and further via the application holes 3 onto the narrow side surface of the workpiece.

Bei dem vorliegenden Ausführungsbeispiel erfolgt die Auftragung des Schmelzklebers über einen keilförmigen Düsenkörper. Diese Auftragung kann jedoch auch durch eine Leimrolle erfolgen, der der Schmelzkleber, wie beschrieben, über den Zuführkanal 4 zugeführt wird.In the present embodiment, the hot melt adhesive is applied via a wedge-shaped nozzle body. However, this application can also be carried out by means of a glue roller, to which the hot-melt adhesive, as described, is fed via the feed channel 4.

Weiterhin besteht die Möglichkeit, die erfindungsgemäße Schmelzvorrichtung zusammen mit bekannten Auftragspistolen für Schmelzkleber zu verwenden, wie sie insbesondere bei der Möbelfertigung im Einsatz sind.Furthermore, there is the possibility of using the melting device according to the invention together with known application guns for hot melt adhesives, such as are used in particular in the manufacture of furniture.
