Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Auftragen von Klebstoff auf ein mit einer Folie zu beschichtendes Werkstück, insbesondere ein Möbelteil aus Holz oder Holzwerkstoff.The invention relates to a method and a device for application of adhesive to a workpiece to be coated with a film, in particular a piece of furniture made of wood or wood-based material.
Werkstücke, die in einer Warmpresse, beispielsweise nach dem aus der Patentschrift DE 43 07 816 C2 der Anmelderin bekannten Verfahren, mit einer Folie beschichtet werden sollen, müssen unmittelbar vor Einbringen in die Warmpresse mit Klebstoff versehen werden. Dieser Klebstoff muß auf die gesamte Oberfläche des Werkstücks aufgetragen werden, die mit einer Folie bedeckt werden soll. Dies ist vor allem dann nicht unproblematisch, wenn das zu beschichtende Werkstück keine ebene Oberfläche aufweist, wie dies beispielsweise bei Formteilen, bei Möbelfronten mit Ausfräsungen und bei Holzwerkstoffplatten mit profilierten Außenkanten der Fall ist.Workpieces that are in a hot press, for example after that from the Patent DE 43 07 816 C2 known to the applicant, with a film to be coated must be immediately before insertion into the hot press with adhesive. This glue must to be applied to the entire surface of the workpiece using should be covered with a film. Above all, this is not without problems, if the workpiece to be coated does not have a flat surface, like this for example with molded parts, with furniture fronts with cutouts and the case for wood-based panels with profiled outer edges is.
Der Auftrag von Klebstoff auf die Oberfläche eines solchen Werkstücks wird daher üblicherweise in Spritztechnik vorgenommen: Ein zweikomponentiger Klebstoff wird auf die mit Folie zu beschichtende Oberfläche des Werkstücks aufgesprüht, so daß auch Fräsungen und Kanten des Werkstücks beleimt werden. Problematisch ist hierbei zum einen, daß in der Spritztechnik immer ein Overspray anfällt, der hinsichtlich möglicher gesundheitlicher Gefahren sowie möglicher Umweltbelastungen bedenklich sein kann und unerwünschte Verluste an Klebstoff mit sich bringt, und zum anderen, daß mit dem Spritzauftrag an der zu beschichtenden Oberfläche des Werkstücks Feinstaub eingeschlossen werden kann, der zu einer unerwünschten Rauhigkeit der Oberfläche führt. Um einen Spritzauftrag des Klebstoffs zu ermöglichen, darf dieser nur eine niedrige Viskosität aufweisen, was bei den meistens verwendeten wasserlöslichen Klebstoffen einen relativ hohen Wasseranteil bedingt. Insbesondere bei Werkstücken aus Holz oder Holzwerkstoff ist ein Klebstoff mit hohem Wasseranteil jedoch von Nachteil, da dieser zur Spannquellung an der Oberfläche des Werkstücks führen kann. Vor allem die offenporigen und daher hygoskopischen Kanten von Möbelteilen aus Holzwerkstoff, wie Span- und Faserplatten, sind hier besonders empfindlich.The application of glue to the surface of such a workpiece is therefore usually carried out in spray technology: a two-component Adhesive is applied to the surface of the film to be coated Workpiece sprayed on, so that milling and edges of the workpiece be glued. One problem here is that in the Spray technology always produces an overspray that is potentially harmful to health Dangers and possible environmental pollution are questionable can be and causes undesirable loss of adhesive, and other that with the spray application on the surface to be coated of the workpiece can be trapped in fine dust, which leads to an undesirable Roughness of the surface leads. To a spray order of the To enable adhesive, it must only have a low viscosity, which is one of the most common water-soluble adhesives relatively high water content. Especially with workpieces However, wood or wood-based material is an adhesive with a high water content disadvantageous because it swells on the surface of the workpiece can lead. Especially the open-pore and therefore hygoscopic Edges of furniture parts made of wood-based materials, such as chipboard and fiberboard, are particularly sensitive here.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Auftragen von Klebstoff auf ein mit einer Folie zu beschichtendes Werkstück vorzuschlagen, mit dem bzw. mit der das Auftragen des Klebstoffs unaufwendiger und kostengünstiger wird und Spannquellungen sowie unerwünschte Rauhigkeiten der zu beschichtenden Oberfläche weitgehend vermieden bzw. reduziert werden können.Starting from this prior art, the object of the invention based on a method and a device for applying adhesive to propose on a workpiece to be coated with a film, with the or with which the application of the adhesive is less complex and less expensive and swellings and unwanted roughness of the surface to be coated are largely avoided or reduced can.

Nach der Erfindung wird der Klebstoff auf das zu beschichtende Werkstück nicht mehr aufgespritzt, sondern zunächst einer elastisch verformbaren Auftragswalze aufgegeben und dann mit dieser, durch Abrollen auf der zu beschichtenden Oberfläche des Werkstücks, auf das Werkstück aufgebracht. Der weiche, verformbare Belag der Auftragswalze stellt dabei sicher, daß der Klebstoff auch an Teilbereiche der Kanten, an die Flanken von Erhebungen und in Ausnehmungen der zu beschichtenden Oberfläche gelangt. Gegenüber der herkömmlichen Spritzmethode wird der Klebstoffauftrag wesentlich gleichmäßiger und genauer dosierbar; der Klebstoffverlust durch Overspray entfällt ganz. Das Auftragen des Klebstoffs mittels einer Auftragswalze ermöglicht außerdem einen Klebstoffauftrag im Durchlaufverfahren. Auch die Verwendung eines einkomponentigen Klebstoffs ist problemlos möglich. Da die Viskosität des Klebstoffs sowie sein Festkörpergehalt wesentlich höher sein können, als beim herkömmlichen Spritzauftrag, reduzieren sich auch die Probleme hinsichtlich Spannquellung und Oberflächenrauhigkeit. Die erfindungsgemäß mögliche, sehr gleichmäßige Verteilung des Klebstoffs auf der zu beschichtenden Oberfläche des Werkstücks bietet schließlich auch eine qualitative Verbesserung des fertigen Werkstücks. Insofern ein wasserlöslicher Klebstoff verwendet wird, gibt es keinerlei Bedenken hinsichtlich der Arbeitssicherheit und der Umweltbelastungen.According to the invention, the adhesive is applied to the workpiece to be coated no longer sprayed on, but first an elastically deformable Application roller and then with this, by rolling on the coating surface of the workpiece, applied to the workpiece. The soft, deformable coating of the application roller ensures that the adhesive also on parts of the edges, on the flanks of elevations and in recesses of the surface to be coated reached. Compared to the conventional spraying method, the adhesive is applied can be dosed much more evenly and precisely; the loss of glue Overspray is completely eliminated. Applying the adhesive using a Applicator roller also enables continuous adhesive application. The use of a one-component adhesive is also possible without any problems. Because the viscosity of the adhesive as well as its solids content can be significantly higher than with conventional spray application, also reduce the problems with tension swelling and Surface roughness. The very uniform possible according to the invention Distribution of the adhesive on the surface of the workpiece to be coated finally also offers a qualitative improvement of the finished Workpiece. If a water-soluble adhesive is used, there is no concerns about occupational safety and environmental pollution.
Die erfindungsgemäße Vorrichtung umfaßt eine elastisch verformbare Auftragswalze zum Auftragen von Klebstoff auf die zu beschichtende Oberfläche des Werkstücks sowie eine Dosiereinrichtung zum Aufgeben des Klebstoffs auf die Auftragswalze. Eine solche Vorrichtung bietet die eben geschilderten Vorteile des Verfahrens und ist ohne weiteres für eine Durchlaufbeleimung der Werkstücke geeignet.The device according to the invention comprises an elastically deformable application roller for applying adhesive to the surface to be coated of the workpiece and a metering device for applying the adhesive on the applicator roller. Such a device offers the just described Advantages of the method and is readily available for continuous gluing of the workpieces.
Wenn die Auftragswalze zum Auftragen des Klebstoffs auf das Werkstück mehr als eine Umdrehung ausführt, kann ein nachfolgender ungleichmäßiger Klebstoffauftrag durch etwa ungleichmäßig auf der Auftragswalze verbliebenen, überschüssigen Klebstoff dadurch verhindert werden, daß die Auftragswalze mit einem ersten Rakel ausgerüstet wird, der den überschüssigen Klebstoff von der Auftragswalze entfernt, bevor diese mit neuem Klebstoff versehen wird. Hierbei bietet es Vorteile, wenn der mit dem Rakel entfernte, überschüssige Klebstoff gereinigt und wieder zur Auftragswalze zurückgeführt wird. Hierzu kann die erfindungsgemäße Vorrichtung mit einer Umwälzpumpe ausgerüstet werden, die für einen Klebstoffumlauf sorgt.When the applicator roller to apply the adhesive to the workpiece executes more than one revolution, a subsequent one may be uneven Adhesive application due to unevenly remaining on the application roller Excess adhesive can be prevented by the Applicator roller is equipped with a first squeegee, the excess Adhesive removed from the applicator roller before starting with a new one Adhesive is provided. Here it offers advantages if the with the Squeegee removed, excess adhesive cleaned and back to the application roller is returned. For this purpose, the device according to the invention be equipped with a circulating pump, which is used for an adhesive circulation worries.
Das Aufbringen des Klebstoffs auf die Auftragswalze erfolgt vorzugsweise mit einer Dosierwalze, die bis auf einen Spalt an die Auftragswalze herangeführt ist und vorzugsweise gegensinnig zur Auftragswalze gedreht wird. Der frische Klebstoff kann dann in diesen Spalt gegeben werden, wobei die Auftragswalze den Klebstoff aus dem Spalt entnimmt, mit sich führt und auf der Werkstückoberfläche abträgt. Die Menge des mitgeführten Klebstoffs hängt dabei von der Breite des Spalts bzw. von der Andruckkraft zwischen Auftragswalze und Dosierwalze sowie von der Drehgeschwindigkeit der Dosierwalze ab, kann also auf einfache Weise geregelt werden.The adhesive is preferably applied to the application roller with a metering roller that comes up to a gap on the applicator roller is and is preferably rotated in the opposite direction to the applicator roller. The fresh glue can then be placed in this gap, the Application roller removes the adhesive from the nip, carries it with it and opens it of the workpiece surface. The amount of glue carried depends on the width of the gap or the pressure force between Applicator roller and metering roller as well as the speed of rotation of the Dosing roller, can be regulated in a simple manner.
Die Auftragswalze trägt vorzugsweise einen elastisch verformbaren, weichen Belag mit 15 bis 35 Shore A.The application roller preferably carries an elastically deformable, soft Covering with 15 to 35 Shore A.
Zur Vereinfachung des Arbeitsablaufs, zur Eliminierung unnötiger Fehlerquellen und zur Reduzierung des Reinigungsaufwands für die Arbeitsgeräte ist es vorteilhaft, wenn ein einkomponentiger Klebstoff verwendet wird. Dieser weist vorzugsweise eine Viskosität zwischen 1000 mPas und 3000 mPas auf.To simplify the workflow, to eliminate unnecessary sources of error and to reduce the cleaning effort for the tools it is advantageous if a one-component adhesive is used. This preferably has a viscosity between 1000 mPas and 3000 mPas on.
