The The invention relates to an adhesive melter with a slot nozzle application unit for Melting and subsequent Application of granulated or block-shaped adhesive, wherein the Smelter from a container with a sealing lid an electric heated heating grate and a movable pressure plate and an electrically temperature-controlled Underfloor heating exists and the Schmelzer a pump for molten Adhesive, a filter and a slot die are arranged downstream.
In der Holzindustrie werden bekanntlich Furniere, Folien oder sonstige Überzugsmaterialien mit einem Heißkleber auf ein Trägermaterial aufgeklebt. Dabei wird der heiße Klebstoff über eine Düse, Walzen oder Rakel kontinuierlich auf das Beschichtungsmaterial aufgetragen.In The wood industry is known veneers, films or other coating materials with a hot glue on a carrier material glued. This is the hot Glue over a nozzle, Rollers or knife continuously applied to the coating material.
Als Klebstoff werden Schmelzklebstoffe wie Polyurethan (PUR), Amorph-Poly-Alpha-Olefin (APAO) oder Ethylen-Vinyl-Acetat (EVA) genutzt, die in Blockform oder auch als Granulat geliefert werden. In Schmelzern werden diese Klebstoffe geschmolzen und damit verflüssigt.When Adhesives are hot melt adhesives such as polyurethane (PUR), amorphous poly-alpha-olefin (APAO) or Ethylene vinyl acetate (EVA) used in block or as well Granules are delivered. In smelters, these are adhesives melted and liquefied.
Es sind Tankschmelzer bekannt, oder Kolbenschmelzer wie beispielsweise der VSK40 der Fa. DelleVedove, die Klebstoffe in einem Kleberschacht aufschmelzen und einem Kleberauftragsaggregat, wie einer Walze oder einer Düse zuführen.It Tankschmelzer are known, or Kolbenschmelzer such as the VSK40 from the company DelleVedove, which melt adhesives in a glue shaft and an adhesive application unit, such as a roller or a nozzle.
Solche Vorschmelzer sind separate Aggregate, bei denen ein Kolben auf den ungeschmolzenen Kleber drückt, und von denen über eine Pumpe und über Schläuche der Kleber dem Kleberauftragsaggregat zugeführt wird. Um ein Erkalten und damit ein Verhärten des Klebstoffs zu vermeiden, müssen die Pumpe, die Schläuche und das Kleberauftragsaggregat ständig auf dem Niveau der Verarbeitungstemperatur des Klebers gehalten werden. Dies ist nur über aufwendig geregelte Heizkreise zu erreichen, damit eine Zersetzung des Klebers vermieden wird.Such Pre-melters are separate units in which a piston on the presses unmelted glue, and of those about a pump and over hoses the adhesive is supplied to the glue application unit. To a cold and with it a hardening To avoid the glue, the Pump, the hoses and the glue application unit constantly at the level of processing temperature of the adhesive. This is only about elaborately controlled heating circuits to achieve, so that a decomposition of the adhesive is avoided.
Aus der WO 00/02667 ist ein Düsenaggregat mit eingebauter elektrischer Heizung bekannt.Out WO 00/02667 is a nozzle unit with Built-in electric heater known.
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 It is an object of the invention to provide a more compact and simpler structure Melting and Nozzle application unit with integrated pump and specify where several separate heaters and airbags saved, and which easier in a production environment to integrate.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.advantageous embodiments 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.Of the Schmelzer is for melting commercially available solid adhesives in Block or granule form provided. Into the container, the adhesive is introduced and then the container closed by the lid. This will change the fresh air supply prevented, and the adhesive reacts less with the air. Of the solid adhesive lies in the container on a heating grate, which is to be melted with electrical energy is supplied, granules is introduced, the heating grate is off completely enclosed. In the container There is a rotatably mounted pressure plate, which is fixed to the Adhesive presses and thus speed up the melting process. By the fast melting of the adhesive under pressure, the heating grate is cooled, and there is none local overheating.
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.Of the melted glue collects on the bottom of the container. In This floor is integrated with a heater that collects the glue controlled at a temperature above its melting point holds. The Control unit ensures constant temperature. The molten adhesive is removed from the container via a Pump to the nozzle application unit promoted. Since the pre-melt container, the glue pump and the filter housing of the nozzle application unit directly connected to each other, the same heating also affects these components. additional regulated heaters for this Components are not needed.
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.To the rapid melting of the solid adhesive is on the axis of rotation the pressure plate from the outside, exerted a defined compressive force on the adhesive. there is the end position of the pressure plate by a sensor, for example a limit switch, detected and sent to the controller and the operator reported. The energy supply for the heating grate is retained only as long as the pressure plate still has not reached its end position on the heating grid. The final position is achieved when the solid adhesive is completely liquefied. Then the heating energy the heating grate is switched off and the pressure plate in its initial position back turned. So that the pressure plate only unmelted glue in solid Form condensed on the heating grate, it is with slit-shaped openings provided by the liquid Glue can flow.
Nach dem Einbringen weiteren Klebers durch den Bediener wird die elektrische Versorgung des Heizrostes mit der Drehbewegung der Druckplatte wieder eingeschaltet und der Kleber auf den Heizrost gedrückt.To the introduction of additional adhesive by the operator is the electrical Supply of the heating grate with the rotation of the pressure plate again switched on and pressed the glue on the heater.
Die Ausgestaltung der Erfindung ist in den Figuren beispielhaft beschrieben.The Embodiment of the invention is described by way of example in the figures.
