Es ist Aufgabe der Erfindung, ein kompakteres und einfacher aufgebautes Aufschmelz- und Düsenauftragsaggregat mit integrierter Pumpe und anzugeben, bei dem mehrere separate Heizungen und Heizschläuche eingespart sind, und welches einfacher in eine Produktionsumgebung zu integrieren ist.It is an object of the invention to provide a more compact and simpler Aufschmelz- and Düsenauftragsaggregat with integrated pump and, in which several separate heaters and airbags are saved, and which is easier to integrate into a production environment.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Der Schmelzer ist zum Aufschmelzen handelsüblicher fester Klebstoffe in Block- oder Granulatform vorgesehen. In den Behälter wird der Klebstoff eingebracht und dann der Behälter durch den Deckel verschlossen. Dadurch wird die Frischluftzufuhr unterbunden, und der Klebstoff reagiert weniger mit der Luft. Der feste Klebstoff liegt in dem Behälter auf einem Heizrost auf, der zum Aufschmelzen mit elektrischer Energie versorgt wird, ist Granulat eingebracht, wird der Heizrost davon komplett umschlossen. In dem Behälter befindet sich eine drehbar gelagerte Druckplatte, die auf den festen Klebstoff drückt und damit den Schmelzvorgang beschleunigt. Durch das schnelle Schmelzen des Klebstoffs unter Druck wird der Heizrost gekühlt, und es kommt zu keinen lokalen Überhitzungen. Der geschmolzene Kleber sammelt sich auf dem Boden des Behälters. In diesen Boden ist eine Heizung integriert, die den gesammelten Kleber geregelt auf einer Temperatur oberhalb seines Schmelzpunktes hält. Die Regeleinheit sorgt für konstante Temperatur. Der geschmolzene Kleber wird aus dem Behälter über eine Pumpe zu dem Düsenauftragsaggregat gefördert. Da der Vorschmelzbehälter, die Kleberpumpe und das Filtergehäuse des Düsenauftragsaggregates direkt miteinander verbunden sind, wirkt die gleiche Heizung auch auf diese Komponenten. Zusätzliche geregelte Heizungen für diese Komponenten werden nicht benötigt. Zum schnellen Schmelzen des festen Klebstoffs wird auf die Drehachse der Druckplatte von außen, eine definierte Druckkraft auf den Klebstoff ausgeübt. Dabei wird die Endlage der Druckplatte durch einen Sensor, beispielsweise einen Endschalter, erfasst und an die Steuerung und den Bediener gemeldet. Die Energiezufuhr für den Heizrost bleibt nur solange erhalten, wie die Druckplatte noch nicht ihre Endstellung auf dem Heizrost erreicht hat. Die Endstellung wird erreicht, wenn der feste Klebstoff vollständig verflüssigt ist. Dann wird die Heizenergie des Heizrostes abgeschaltet und die Druckplatte in ihre Ausgangslage zurück gedreht. Damit die Druckplatte nur ungeschmolzenen Kleber in fester Form auf dem Heizrost verdichtet, ist sie mit schlitzförmigen Öffnungen versehen, durch die flüssiger Kleber fließen kann.The melter is intended for melting commercially available solid adhesives in block or granular form. The adhesive is introduced into the container and then the container is closed by the lid. This stops the supply of fresh air and the adhesive reacts less with the air. The solid adhesive is in the container on a heating grate, which is supplied for melting with electrical energy, granules is introduced, the heating grate is completely enclosed. In the container there is a rotatably mounted pressure plate which presses on the solid adhesive and thus accelerates the melting process. Due to the rapid melting of the adhesive under pressure, the heating grate is cooled, and there is no local overheating. The molten adhesive collects on the bottom of the container. In this floor, a heater is integrated, which holds the collected adhesive regulated at a temperature above its melting point. The control unit ensures a constant temperature. The molten adhesive is delivered from the container via a pump to the nozzle application unit. Since the pre-melt container, the glue pump and the filter housing of the nozzle application unit are directly connected, the same heater also acts on these components. Additional regulated heaters for these components are not needed. For rapid melting of the solid adhesive is applied to the axis of rotation of the pressure plate from the outside, a defined compressive force on the adhesive. The end position of the printing plate is detected by a sensor, such as a limit switch, and reported to the controller and the operator. The energy supply for the heating grate is retained only as long as the pressure plate has not yet reached its end position on the heating grate. The end position is reached when the solid adhesive is completely liquefied. Then the heating energy of the heating grate is switched off and the pressure plate is rotated back to its original position. So that the pressure plate compacts only unmelted adhesive in solid form on the heating grate, it is provided with slit-shaped openings through which liquid adhesive can flow.
Nach dem Einbringen weiteren Klebers durch den Bediener wird die elektrischeAfter the introduction of further adhesive by the operator, the electrical
Versorgung des Heizrostes mit der Drehbewegung der Druckplatte wieder eingeschaltet und der Kleber auf den Heizrost gedrückt.Supply of the heating grate with the rotary movement of the pressure plate switched on again and pressed the adhesive on the heater.

Fig. 4 zeigt einen Querschnitt durch einen Schmelzer mit angehobener Druckplatte.Fig. 4 shows a cross section through a melter with raised pressure plate.
In Fig. 1 ist der Querschnitt eines Schmelzers dargestellt. Der Behälter 1 ist mit dem Deckel 3 verschlossen. In dem Behälter befindet sich der elektrisch betriebene Heizrost 4 auf dem der frische Block von festem Klebstoff 7 liegt. Auf den Block 7 drückt die Druckplatte 2, die auf der Welle 8 drehbar gelagert ist. Die untere Endstellung der Druckplatte wird mittels des Sensors 9 an die Steuerung 6 übermittelt. In dem Boden des Behälters 1 ist die elektrische geregelte Heizung 5 integriert. Über den Auslass 11 gelangt flüssiger Kleber zu der Pumpe 10, die den Kleber zu dem Kleberauftragsaggregat 12 befördert, das hier als Düse dargestellt ist. Zwischen der Düse 12 und der Pumpe 10 befindet sich die Filtereinheit 15. Durch die Düse wird der - A - flüssige Kleber auf das Verarbeitungsmaterial 13, hier etwa eine Folie oder Papier, aufgetragen.In Fig. 1, the cross section of a melter is shown. The container 1 is closed with the lid 3. In the container is the electrically operated heating grate 4 on which the fresh block of solid adhesive 7 is located. On the block 7 presses the pressure plate 2, which is rotatably mounted on the shaft 8. The lower end position of the pressure plate is transmitted by means of the sensor 9 to the controller 6. In the bottom of the container 1, the electric regulated heater 5 is integrated. Via the outlet 11, liquid adhesive passes to the pump 10, which conveys the adhesive to the glue application unit 12, here shown as a nozzle. Between the nozzle 12 and the pump 10 is the filter unit 15. Through the nozzle is the - A - liquid adhesive on the processing material 13, here about a foil or paper, applied.
Die Pumpe 10, der Filter 15 und die Düse 12 sind in bzw. an einem massiven Block 17 angeordnet, der sich auf ganzer Länge unter dem Heizboden 5 erstreckt und dort einen engen Wärmeleitkontakt hat.The pump 10, the filter 15 and the nozzle 12 are arranged in or on a solid block 17, which extends over the entire length under the heating bottom 5 and there has a tight Wärmeleitkontakt.
Die Welle 8 ist durch die Behälterwandung geführt, und von außen mittels Hebel und Pneumatikzylinder betätigt, so dass Druck auf den Klebstoff im Behälter aufbaut werden kann. Da der Behälterboden und der Wärmeleitblock 17 eng wärmeleitend verbunden sind, kann die elektrische Heizung 5 entweder im Behälterboden oder in den benachbarten Bereich des Wärmeleitblocks 17 oder zwischen diesen angeordnet sein. Ebenso kann der Temperatursensor 18 im Boden oder in Block 17 angeordnet sein . Das Temperatursensorsignal ist in die schematisch dargestellte Steuervorrichtung geführt, von der der Heizstrom der Bodenheizung 5 geregelt abgegeben wird. Die Schlitzdüse hat eine separate Temperaturregelung, um die optimale Auftragstemperatur des Klebers direkt vor dem Applizieren auf das Material (13) einstellen zu können.The shaft 8 is guided through the container wall, and actuated from the outside by means of lever and pneumatic cylinder, so that pressure can be built up on the adhesive in the container. Since the container bottom and the heat-conducting block 17 are connected in a heat-conducting manner, the electric heater 5 can be arranged either in the container bottom or in the adjacent region of the heat-conducting block 17 or between them. Likewise, the temperature sensor 18 may be disposed in the ground or in block 17. The temperature sensor signal is fed into the control device shown schematically, from which the heating current of the bottom heater 5 is discharged regulated. The slit nozzle has a separate temperature control to set the optimum application temperature of the adhesive just before applying to the material (13).
In Fig. 2 ist der gleiche Schmelzer im Querschnitt dargestellt, wobei der Block festen Klebstoffes 7 schon weitestgehend abgeschmolzen ist. Auf dem Boden des Behälters 1 hat sich flüssiger Klebstoff 14 gesammelt, der durch den Auslass 11 über die tieferliegende Pumpe 10 unmittelbar zur Düse 12 gefördert und auf das vorbeilaufende Verarbeitungsmaterial 13 aufgetragen wird. Die Heizung 5 hält die Temperatur des flüssigen Klebers 14, des Vorschmelzbeckens, der Pumpe 10 und des Filtersystems der Düse die alle thermisch miteinander eng gekoppelt sind, auf einer konstanten Temperatur. Die Druckplatte hat sich weiter gedreht. Der Heizrost 4 wird weiter mit Energie zum Abschmelzen versorgt.In Fig. 2 the same melter is shown in cross section, wherein the block of solid adhesive 7 has already been largely melted. Liquid adhesive 14 has accumulated on the bottom of the container 1, which is conveyed through the outlet 11 via the lower-lying pump 10 directly to the nozzle 12 and applied to the passing processing material 13. The heater 5 keeps the temperature of the liquid adhesive 14, the pre-melt pool, the pump 10 and the filter system of the nozzle, all of which are thermally coupled to each other, at a constant temperature. The pressure plate has turned further. The heating grate 4 is further supplied with energy for melting.
In Fig. 3 ist der gleiche Schmelzer im Querschnitt dargestellt, wobei der Kleber 14 vollständig verflüssigt ist. Hat die Druckplatte 2 die Stellung unten erreicht, wird die Heizenergiezuiuhr für den Heizrost 4 abgeschaltet. Die Druckplatte 2 kann aufgrund ihrer schlitzförmigen Öffnungen (16) leicht durch den flüssigen Kleber 14 zurückgedreht werden, damit weiterer Klebstoff eingebracht und aufgeschmolzen werden kann. In Fig. 4 ist der Schmelzer so dargestellt, dass der Kleber 14 vollständig verflüssigt ist und die Druckplatte 2 wieder in ihre Anfangsstellung zurückgedreht ist. Die elektrische Versorgung Heizrostes 4 bleibt abgeschaltet. Der Behälter 1 kann nun mit neuem festem Klebstoff beladen werden. In Fig. 3, the same melter is shown in cross-section, wherein the adhesive 14 is completely liquefied. If the pressure plate 2 has reached the position below, the Heizenergiezuiuhr for the heater 4 is turned off. The pressure plate 2 can be easily rotated back through the liquid adhesive 14 due to their slot-shaped openings (16), so that further adhesive can be introduced and melted. In Fig. 4, the melter is shown so that the adhesive 14 is completely liquefied and the pressure plate 2 is rotated back to its initial position. The electrical supply heating grate 4 remains switched off. The container 1 can now be loaded with new solid adhesive.
