Flexible Auftragseinheit für partielle Beschichtung Flexible application unit for partial coating
Die vorliegende Erfindung betrifft eine Vorrichtung zum Beschichten der seitlichen Kantenflächen von langgestreckten Werkstücken mit einem flüssigen Beschichtungsmedium bestehend aus einem Beschichtungskopf mit einem in Transportrichtung des Werkstückes verlaufenden Beschichtungsschlitz, in dem mindestens eine an einer Zuführleitung für das Beschichtungsmedium angeschlossene Beschichtungsdüse, angeordnet ist. Des weiteren betrifft die vorliegende Erfindung ein Verfahren zum Beschichten von seitlichen Kantenflächen von langgestreckten Werkstücken.The present invention relates to a device for coating the lateral edge surfaces of elongate workpieces with a liquid coating medium consisting of a coating head with a coating slot running in the transport direction of the workpiece, in which at least one coating nozzle connected to a supply line for the coating medium is arranged. Furthermore, the present invention relates to a method for coating lateral edge surfaces of elongated workpieces.
Die Kanten von langgestreckten Werkstücken, beispielsweise Profile aus Holz oder Kunststoff, müssen immer öfter beispielsweise mit einem Lack und/oder einem Klebstoff beschichtet werden. Diese Beschichtung erfolgt oftmals mit Beschichtungsköpfen, die ein Eintrittsende und ein Austrittsende aufweisen, das dem Kantenquerschnitt des zu beschichtenden Werkstückes angepasst ist. Da es eine Vielzahl von unterschiedlichen zu beschichtenden Kantenformen gibt, und die Herstellung eines jeweils dafür maßgeschneiderten Beschichtungskopfes vergleichsweise aufwendig ist, besteht insbesondere bei Betrieben, bei denen viele unterschiedliche Kanten von langgestreckten Werkstücken beschichtet werden müssen, der Bedarf einer universell einsetzbaren Vorrichtung zum Beschichten der seitlichen Kantenflächen von langgestreckten Werkstücken.The edges of elongated workpieces, for example profiles made of wood or plastic, have to be coated more and more often, for example with a varnish and / or an adhesive. This coating is often carried out with coating heads which have an inlet end and an outlet end which is adapted to the edge cross section of the workpiece to be coated. Since there are a large number of different edge shapes to be coated, and the production of a coating head that is tailor-made for each of them is comparatively complex, there is a need, particularly in companies where many different edges of elongated workpieces have to be coated, for a universally applicable device for coating the side Edge surfaces of elongated workpieces.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zum Beschichten der seitlichen Kantenflächen von langgestreckten Werkzeugen zur Verfügung zu stellen, die an unterschiedliche Kantenformen angepasst werden kann.The present invention is therefore based on the object of providing a device for coating the lateral edge surfaces of elongated tools, which can be adapted to different edge shapes.
Gelöst wird die Aufgabe erfindungsgemäß, durch eine Vorrichtung zum Beschichten der seitlichen Kantenflächen von langgestreckten Werkstücken mit einem flüssigen Beschichtungsmedium, bestehend aus einem Beschichtungskopf mit einem in Transportrichtung des Werkstückes verlaufenden Beschichtungsschlitzes in dem mindestens eine an eine Zuführleitung für das Beschichtungsmedium angeschlossene Beschichtungsdüse angeordnet ist, wobei die Beschichtungsdüse verschieblich angeordnet ist. Es war für den Fachmann durchaus erstaunlich und nicht zu erwarten, dass es mit der erfindungsgemäßen Vorrichtung gelingt, eine Vielzahl von unterschiedlichen seitlichen Kantenflächen von langgestreckten Werkstücken einwandfrei zu beschichten. Die erfindungsgemäße Vorrichtung ist einfach und kostengünstig herzustellen und in kürzester Zeit auf die Kantenflächen des jeweiligen Werkstückes anpassbar.The object is achieved according to the invention by a device for coating the lateral edge surfaces of elongated workpieces with a liquid coating medium, consisting of a coating head with a coating slot running in the transport direction of the workpiece, in which at least one coating nozzle connected to a supply line for the coating medium is arranged, wherein the coating nozzle is arranged displaceably. It was quite astonishing for the person skilled in the art and it was not to be expected that it would be possible with the device according to the invention to coat a large number of different lateral edge surfaces of elongated workpieces properly. The device according to the invention is simple and inexpensive to manufacture and can be adapted to the edge surfaces of the respective workpiece in the shortest possible time.

Vorzugsweise weist der Beschichtungskopf eine Absaugung auf, mit der überschüssiges Material, das mit den Beschichtungsdüsen auf das Werkstück aufgetragen wurde, wieder abgesaugt werden kann. Das abgesaugte Material wird vorzugsweise aufgefangen und in den Herstellungsprozess rezykliert, so dass kein Beschichtungsmaterial verloren geht.The coating head preferably has a suction device with which excess material which has been applied to the workpiece with the coating nozzles can be suctioned off again. The extracted material is preferably collected and recycled into the manufacturing process so that no coating material is lost.
Vorzugsweise weist der Beschichtungskopf am Eintrittsende und am Austrittsende vorzugsweise jeweils eine Abdeckung auf, in die eine Ausnehmung eingearbeitet ist, die im wesentlichen an den Kantenquerschnitt des zu beschichtenden Werkstückes angepasst ist. Diese Ausführungsform der vorliegenden Erfindung garantiert zum einen, dass kein Material den Beschichtungskopf verlässt. Des weiteren vereinfacht diese Ausführungsform der vorliegenden Erfindung den Aufbau eines Unterdrucks zum Absaugen von überschüssigem Beschichtungsmedium.The coating head preferably has a cover at the inlet end and at the outlet end, into which a recess is machined, which is essentially adapted to the edge cross section of the workpiece to be coated. On the one hand, this embodiment of the present invention guarantees that no material leaves the coating head.

Figur 1 zeigt die erfindungsgemäße Vorrichtung zum Beschichten der seitlichen Kantenflächen von langgestreckten Werkstücken mit einem flüssigen Beschichtungsmedium in zwei Ansichten. Die Vorrichtung weist einen Beschichtungskopf 1 mit einem in Transportrichtung des Werkstückes verlaufenden Beschichtungsschlitz 2 auf. Im Bereich des Schlitzes 2 sind zwei Beschichtungsdüsen 4, 5 angeordnet, wobei die Beschichtungsdüse 4 in vertikaler Richtung, wie durch den Doppelpfeil 7 dargestellt, verschieblich gelagert ist und die Beschichtungsdüse 5 in horizontaler Richtung, wie durch den Doppelpfeil 6 dargestellt, verschoben werden kann. Die Verschiebung erfolgt jeweils relativ zu dem Beschichtungskopf 1. Die Beschichtungsdüse 4 ist an die Zuführungsleitung 3 und die Düse 5 an die Zuführungsleitung 8 angeschlossen, die sie jeweils mit dem Beschichtungsmedium versorgen. Des weiteren weist der Beschichtungskopf eine weitere Beschichtungsdüse 9 auf, die jedoch nicht relativ zu dem Beschichtungskopf verschiebbar ist. Der Fachmann versteht, dass mit jeder der oben genannten Beschichtungsdüsen das Beschichtungsmedium direkt aufgetragen und/oder aufgesprüht werden kann. Des weiteren verfügt der Beschichtungskopf über eine Absaugung 10, mit der überschüssiges, das heisst für die eigentliche Beschichtung nicht benötigtes Material, von dem Werkstück abgesaugt, rezykliert und wieder verwendet wird. Durch die Doppelpfeile 15 und 16 wird angedeutet, dass der erfindungsgemäße Beschichtungskopf sowohl vertikal als auch horizontal insgesamt verschieblich an der erfindungsgemäßen Vorrichtung gelagert ist.FIG. 1 shows the device according to the invention for coating the lateral edge surfaces of elongated workpieces with a liquid coating medium in two views. The device has a coating head 1 with a coating slot 2 running in the transport direction of the workpiece. In the area of the slot 2, two coating nozzles 4, 5 are arranged, the coating nozzle 4 being displaceably mounted in the vertical direction, as represented by the double arrow 7, and the coating nozzle 5 being displaceable in the horizontal direction, as represented by the double arrow 6. The shift takes place in each case relative to the coating head 1. The coating nozzle 4 is connected to the feed line 3 and the nozzle 5 to the feed line 8, which in each case supply them with the coating medium. Furthermore, the coating head has a further coating nozzle 9, which, however, cannot be displaced relative to the coating head. The person skilled in the art understands that the coating medium is applied and / or applied directly to each of the coating nozzles mentioned above can be sprayed on. Furthermore, the coating head has an extraction device 10, with which excess material, that is to say material not required for the actual coating, is extracted from the workpiece, recycled and reused. The double arrows 15 and 16 indicate that the coating head according to the invention is mounted on the device according to the invention in a displaceable manner both vertically and horizontally.
Figur 2 zeigt den Beschichtungskopf gemäß Figur 1 , wobei in dieser Figur das zu beschichtende Werkstück 20 mit eingezeichnet ist. Das Werkstück 20 wird durch eine Transportvorrichtung (nicht dargestellt) in die Papierebene hinein durch den Beschichtungsschlitz 2 hindurch transportiert. Mit dem Doppelpfeil 21 ist angedeutet, dass die Transportvorrichtung des Werkstückes so ausgelegt ist, dass dieses in vertikaler Richtung verschiebbar ist, so dass die gesamte Vorrichtung nicht nur an unterschiedliche Kantenformen, sondern auch an unterschiedliche Werkstückgrößen und -formen anpassbar ist.FIG. 2 shows the coating head according to FIG. 1, the workpiece 20 to be coated being shown in this figure.

Die Abdeckungen 12, 13 weisen jeweils eine Ausnehmung 14 auf, die im wesentlichen an den Kantenquerschnitt des zu beschichtenden Werkstückes angepasst ist. Der Fachmann versteht, dass bei einer Änderung der Kantenform auch die Abdeckung 12, 13 geändert werden muss. Durch die Abdeckung 12, 13 wird vermieden, dass Beschichtungsmedium den Beschichtungskopf unkontrolliert verlässt und sicher gestellt, dass mit der Absaugung 10 ein hinreichend großer Unterdruck aufgebaut werden kann. Die Abdeckungen 12, 13 sind entsprechend dem Doppelpfeil relativ zu dem Beschichtungskopf vertikal und/oder horizontal verschiebbar. FIG. 3 shows both the inlet end and the outlet end of the coating head (an illustration), each of which is provided with a cover 12, 13, which covers parts of the coating slot 2. The covers 12, 13 each have a recess 14 which is essentially adapted to the edge cross section of the workpiece to be coated. The person skilled in the art understands that if the edge shape is changed, the cover 12, 13 must also be changed.
