Description

Die Erfindung betrifft eine Vorrichtung zum Auftragen von Leim auf zu verleimende Holzteile, mit einer Vorschubeinrichtung für die Holzteile, einem oberhalb der Vorschubbahn angeordneten und quer dazu sich erstreckenden Hohlkörper, der an seiner der Vorschubbahn zugewandten Seite eine oder mehrere Reihen von Austrittsöffnungen aufweist und mit einem Vorratsbehälter für den Leim verbunden ist, und mit einem zwischen der bzw. den Reihen der Austrittsöffnungen und der Vorschubbahn angeordneten, flächigen Leitorgan für die aus den Öffnungen austretende viskose Leimflüssigkeit.The invention relates to a device for applying glue to wooden parts to be glued, with a feed device for the wooden parts, a hollow body arranged above the feed path and extending transversely thereto, which has one or more rows of outlet openings on its side facing the feed path and with one Storage container for the glue is connected, and with a flat guide member arranged between the row or rows of the outlet openings and the feed path for the viscous glue liquid emerging from the openings.

Beim Auftragen von Leim auf zu verbindende Holzteile ist es für eine gute Leimverbindung wichtig, daß auf den Verleimungsflächen ein gleichmäßiger und in der Stärke dosierter Leimfilm gebildet wird.When applying glue to wooden parts to be joined, it is important for a good glue connection that a uniform and thickly metered glue film is formed on the gluing surfaces.

In der deutschen Patentanmeldung P 36 12 973 ist eine Vorrichtung zum Auftragen von Leim auf zu verleimende Holzteile beschrieben, bestehend aus einer Vorschubeinrichtung für die Holzteile, einem oberhalb der Vorschubbahn angeordneten und quer dazu sich erstreckenden Hohlkörper, der an seiner der Vorschubbahn zugewandten Seite eine oder mehrere in der Querrichtung verlaufende Reihen von Austrittsöffnungen aufweist und mit einem Vorratsbehälter für den Leim verbunden ist. Zur Bildung eines gleichmäßigen Leimfilms ist zwischen der bzw. den Reihen der am Hohlkörper vorgesehenen Austrittsöffnungen und der Vorschubbahn der zu verleimenden Holzteile ein Leitblech für die aus den Öffnungen austretende Leimflüssigkeit angeordnet.German patent application P 36 12 973 describes a device for applying glue to wooden parts to be glued, consisting of a feed device for the wooden parts, a hollow body which is arranged above the feed path and extends transversely thereto and which has one or. On its side facing the feed path has a plurality of rows of outlet openings running in the transverse direction and is connected to a storage container for the glue. To form a uniform glue film, a guide plate for the glue liquid emerging from the openings is arranged between the row or rows of the outlet openings provided on the hollow body and the feed path of the wooden parts to be glued.

Durch turbulente Luftbewegung, im wesentlichen hervorgerufen durch den Luftstrom vor dem Leitblech, wenn die Holzteile mit hoher Vorschubgeschwindigkeit an die Auftragsvorrichtung herangeführt werden, kann es zu Störungen, beispielsweise Unterbrechungen oder kurzzeitigem Abreißen des Leimfilms kommen.Turbulent air movement, essentially caused by the air flow in front of the guide plate, when the wooden parts are brought up to the application device at a high feed rate, can lead to malfunctions, for example interruptions or short-term tearing off of the adhesive film.

Dementsprechend bestand die Aufgabe, bei einer Vorrichtung zum Auftragen von Leim auf zu verleimende Holzteile der eingangs geschilderten Art Maßnahmen zu treffen, durch die die von der Luftbewegung herrühenden Störungen des Leimfilms vermieden werden können.Accordingly, the object was to take measures in a device for applying glue to wooden parts to be glued, of the type described at the outset, by means of which the glue film disruptions caused by air movement can be avoided.

Die Lösung der Aufgabe besteht darin, daß am Leitorgan und/oder im Bereich des Leitorgans Luftstau verhindernde Einrichtungen vorgesehen sind.The solution to the problem is that devices preventing air congestion are provided on the guide member and / or in the area of the guide member.

Die entsprechend der Erfindung gestaltete Vorrichtung ist anhand mehrerer in der Zeichnung schematisch dargestellter Ausführungsformen nachfolgend näher beschrieben.The device designed according to the invention is described in more detail below with reference to several embodiments shown schematically in the drawing.

Wie in Figur 1 gezeigt, besteht die Vorrichtung zum Auftragen von Leim im wesentlichen aus dem eigentlichen Auftragsorgan 1, einem über eine Pumpe 2 und Versorgungsleitungen 3 damit in Verbindung stehenden Vorratsbehälter 4 sowie aus einer unterhalb des Auftragsorgans befindlichen Vorschub­einrichtung 5 für die mit Leim zu beschichtenden Holzteile 6.As shown in FIG. 1, the device for applying glue consists essentially of the actual application element 1, a storage container 4 connected to it via a pump 2 and supply lines 3, and a feed device 5 located below the application element for the glue to be coated Wooden parts 6.

Das Auftragsorgan ist in der bevorzugten Ausführungsform der Vorrichtung ein quer über die Vorschubbahn des Holzteiles 6 sich erstreckender zylindrischer Hohlkörper 7 runden oder rechteckigen Querschnitts, der an seiner der Vorschubbahn zugewandten Seite eine oder mehrere, in der Längsausdehnung des Hohlkörpers verlaufende Reihen von Austritts­öffnungen 8 in Form von Bohrungen oder Schlitzen aufweist und über die Pumpe 2 mit dem Vorratsbehälter 4 verbunden ist. Die Größe der Öffnungen 8 richtet sich nach der Viskosität der daraus austretenden Flüssigkeit und der Vorschubgeschwindigkeit des Holzteiles; sie liegt gewöhnlich zwischen 0,5 und 5,0 mm. Die Halterung des Hohlkörpers 7 kann in einer dem Fachmann geläufigen und geeigneten Weise vorgenommen werden; sie ist daher nicht weiters gezeigt und beschrieben.In the preferred embodiment of the device, the application member is a cylindrical or hollow cross-section 7 which extends across the feed path of the wooden part 6 and has a round or rectangular cross-section, the side of which faces the feed path has one or more rows of outlet openings 8 in the longitudinal extension of the hollow body of bores or slots and is connected to the reservoir 4 via the pump 2. The size of the openings 8 depends on the viscosity of the liquid emerging therefrom and the feed rate of the wooden part; it is usually between 0.5 and 5.0 mm. The holding of the hollow body 7 can be carried out in a manner familiar and suitable to the person skilled in the art; it is therefore not shown or described any further.

Unterhalb der Öffnungen 8 ist ein Leitorgan in Form eines Leitblechs 9 aus Metall oder Kunststoff angeordnet, welches sich entlang der Öffnungsreihe bzw. -reihen erstreckt. Der aus den Öffnungen auf das Leitblech auftreffende Leim zerfließt auf der Blechoberfläche, so daß ein zusammenhängender und gleichmäßiger Leimfilm entsteht, der vom Leitblech auf die zu beschichtende Werkstückfläche fließt. Sind mehrere Öffnungs­reihen vorhanden, werden die daraus austretenden Leimströme vom Leitblech dadurch erfaßt, daß dieses abgewinkelt oder gebogen verläuft.A guide element in the form of a guide plate 9 made of metal or plastic is arranged below the openings 8 and extends along the row or rows of openings. The glue impinging on the guide plate from the openings flows on the surface of the plate, so that a coherent and uniform film of glue is formed which flows from the guide plate onto the workpiece surface to be coated. If there are several rows of openings, the glue flows escaping from it are detected by the baffle plate in that it is angled or curved.

Da der entstehende Leimfilm die Neigung hat sich zusammenzuziehen, kann er an seinen Rändern geführt und stabilisiert werden. Dieses kann mit Hilfe von starren oder beweglichen Ablaufkanten geschehen, in die das Leitblech seitlich ausläuft.Since the resulting glue film has a tendency to contract, it can be guided and stabilized at its edges. This can be done with the help of rigid or movable drain edges into which the baffle runs out to the side.

Es ist zweckmäßig, unterhalb der Vorschubbahn in Höhe des Leitblechs einen Auffangbehälter 10 für den überschüssigen Leim vorzusehen, der über eine Rückführungsleitung 11 und eine Pumpe 12 mit dem Vorratsbehälter 4 in Verbindung steht.It is expedient to provide a collecting container 10 for the excess glue below the feed path at the level of the guide plate, which is connected to the storage container 4 via a return line 11 and a pump 12.

Ein Unterbrechen oder Abreißen des Leimfilms wird nach der Erfindung dadurch vermieden, daß ein Luftstau vor dem Leitorgan durch konstruktive Maßnahmen am Leitorgan selbst oder in dessen Bereich verhindert wird. Beim Leitblech 9 wird dies durch beliebig geformte Öffnungen 13, beispielsweise runde Öffnungen (Figur 2) oder Schlitze (Figur 3) oder kammartig angeordnete Aussparungen (Figur 4) erreicht, durch die der Luftstrom hindurchtreten kann. Durch die Öffnungen wird der Leimfilm auf dem Leitblech zwar mehrfach geteilt, doch findet danach wieder ein Zusammenfließen statt.An interruption or tearing off of the glue film is avoided according to the invention in that an air build-up in front of the guide element is prevented by constructive measures on the guide element itself or in its area. In the guide plate 9, this is achieved by openings 13 of any shape, for example round openings (FIG. 2) or slots (FIG. 3) or comb-like recesses (FIG. 4) through which the air flow can pass. The glue film on the baffle is divided several times through the openings, but then it flows together again.

Anstelle des perforierten Leitblechs 9 kann auch ein flächiges, netz­artiges Gebilde 14, beispielsweise ein Drahtnetz (Figur 5), oder eine aus dicht nebeneinander hängenden Ketten oder Geflechten 15 gebildete Leit­fläche (Figur 6) vorgesehen werden. Ein Drahtnetz oder nebeneinader hängende Ketten als Leitorgan sind günstig, weil sie sehr nahe an das zu verleimende Holzteil herangeführt werden können und es bei Berührung mit dem Holzteil nicht zu Beschädigung des Leitorgans kommt. Es ist nämlich vorteilhaft, das den Leimfilm bildende Leitorgan möglichst dicht an die zu beaufschlagende Oberfläche heranzuführen, da die Tendenz zum Abreißen des Leimfilms umso geringer ist, je kürzer der freie Fall desselben ist.Instead of the perforated guide plate 9, a flat, net-like structure 14, for example a wire net (FIG. 5), or a guide surface formed from closely hanging chains or braids 15 (FIG. 6) can be provided. A wire mesh or hanging chains next to each other as a guide are cheap because they can be brought very close to the wooden part to be glued and there is no damage to the guide when touching the wooden part. It is namely advantageous to bring the guide element forming the glue film as close as possible to the surface to be acted on, since the tendency for the glue film to tear off is less, the shorter the free fall of the same.

Die Öffnungen 13 des in Figur 2 und 3 dargestellten perforierten Leitblechs 9 oder die des in Figur 5 gezeigten Drahtnetzes können je nach Viskosität des Leims, Grad der Thixotropierung, Durchsatzmenge von Leim pro Zeiteinheit sowie Intensität des Luftstaus eine Weite von 0,5 bis 25 mm aufweisen, die Weite der in Figur 4 dargestellten Aussparungen bzw. die Abstände der in Figur 6 gezeigten, einzelnen, in einer Reihe hängenden Ketten 0,5 bis 25 mm betragen.The openings 13 of the perforated guide plate 9 shown in FIGS. 2 and 3 or those of the wire mesh shown in FIG. 5 can have a width of 0.5 to, depending on the viscosity of the glue, degree of thixotropy, throughput of glue per unit of time and intensity of the air congestion 25 mm, the width of the recesses shown in FIG. 4 or the distances between the individual chains shown in FIG. 6, which are hanging in a row, are 0.5 to 25 mm.

Eine weitere Möglichkeit, einen Luftstau vor dem Leitorgan zu vermeiden, besteht darin, daß die in Vorschubrichtung des Holzteils strömende Luft, wie in Figur 7 gezeigt, mittels vor dem Leitorgan 9 über der Vorschubbahn oder sowohl über als auch unter dieser angeordneter Düsen 16 abgesaugt oder durch daraus gegen die Vorschubrichtung strömende Luft weggeblasen wird.A further possibility of avoiding an air congestion in front of the guide element is that the air flowing in the direction of advance of the wooden part, as shown in FIG is blown away by air flowing against the feed direction.

Eine weitere Maßnahme zur Vermeidung des Luftstaus besteht darin, daß unmittelbar vor dem Leitorgan 9 in der ganzen Breite der Vorschubbahn sowohl über als auch unter dieser Bürsten 17 (Figur 8) angebracht sind, die rechtwinklig schräg oder keilförmig zur Vorschubrichtung gerichtet sind. Die Bürsten bringen den Luftstrom zum Stillstand, da sie unmittelbar über der Oberfläche des Holzteils angeordnet werden können, ohne den Vorschub zu behindern.A further measure to avoid the air congestion is that immediately in front of the guide element 9 in the entire width of the feed path both above and below this brush 17 (Figure 8) are attached, which are directed obliquely at an angle or wedge-shaped to the feed direction. The brushes stop the air flow because they can be placed directly above the surface of the wooden part without hindering the feed.

Schließlich kann die Entstehung des Luftstroms von vornherein verhindert werden, wenn die Stirnseite der zu verleimenden Holzteile 6 mit deren Oberfläche einen spitzen Winkel 18 (Figur 9) bildet.Finally, the formation of the air flow can be prevented from the outset if the end face of the wooden parts 6 to be glued forms an acute angle 18 (FIG. 9) with its surface.

Die vorstehend beschriebenen konstruktiven Maßnahmen können auch miteinander kombiniert werden, insbesondere die nach den Figuren 2 bis 6 mit denen nach den Figuren 7 bis 9, wenn eine besonders gute Wirkung erzielt werden soll.The constructive measures described above can also be combined with one another, in particular those according to FIGS. 2 to 6 with those according to FIGS. 7 to 9 if a particularly good effect is to be achieved.

Zum Auftragen eines Härters für den Leim ist dem mit Austrittsöffnungen 8 versehenen Hohlkörper 7 für den Leim ein weiterer, eben solcher, mit einem Leitblech versehener und mit einem Vorratsbehälter verbundener Hohlkörper zugeordnet (in der Zeichnung nicht dargestellt). Auch für den Härterauftrag können die vorstehend beschriebenen Maßnahmen zur Vermeidung eines Luftstaus vor dem Leitorgan sowohl einzeln als auch kombiniert angewendet werden.To apply a hardener for the glue, the hollow body 7 provided with outlet openings 8 for the glue is assigned a further hollow body which is provided with a guide plate and is connected to a storage container (not shown in the drawing). The measures described above for avoiding air congestion in front of the guide element can also be used both individually and in combination for the hardener application.
