Description
Die Erfindung betrifft eine Furnierzusammensetzmaschine mit mindestens einer Gleitschiene, an der zu verklebende Furnierstücke geführt sind, wobei der Gleitschiene ein Heizelement zugeordnet ist.The invention relates to a Veneierzusammensetzmaschine with at least one slide, are guided on the glued veneer pieces, wherein the slide rail is associated with a heating element.
In Furnierzusammensetzmaschinen werden Furnierstücke an ihren Schmalseiten miteinander verklebt. Die beiden zu verklebenden Furnierstücke werden dazu in parallele Streifen geschnitten, anschließend an ihren Kanten mit Leim versehen und dann in den Furnierzusammensetzmaschinen miteinander verklebt. Hierzu werden die Furnierstücke von Transportsystemen durch eine Klebezone geführt. In der Klebezone wird einerseits Druck auf die zwischen den zu verleimenden Furnierstücken gebildete Fuge ausgeübt und andererseits der Leim mit Wärme ausgehärtet. Die Wärme wird üblicherweise durch Heizelemente in Form von elektrischen Widerstandsdrähten erzeugt, die in wärmeleitfähigen Heizkörpern so angeordnet sind, dass sie ihre Wärme an diese abgeben. Es hat sich als zweckmäßig erwiesen, mehrere Heizkörper hintereinander anzuordnen, um die Wärme über einen größeren Bereich auf die Gleitschiene abzugeben. Die Gleitschiene erstreckt sich somit über mehrere Heizkörper und verhindert dadurch, dass in dem zusammengeleimten Furnier Stoßkanten entstehen. Damit die Gleitschiene nicht an dem Klebstoff in den Fugen haftet, ist die Gleitschiene mit einer Antihaft-Beschichtung versehen. Die Aufgabe der Gleitschiene besteht darin, einerseits die Wärme in den Leim und den benachbarten Fugenbereich zu transportieren und andererseits die einzelnen Furnierstücke plan zu halten.In veneer splicing veneer pieces are glued together on their narrow sides. The two veneer pieces to be bonded are cut into parallel strips, then provided with glue at their edges and then glued together in the veneer assembly machines. For this purpose, the veneer pieces are guided by transport systems through an adhesive zone. In the gluing zone, on the one hand, pressure is exerted on the joint formed between the veneer pieces to be glued, and on the other hand the glue is cured with heat. The heat is usually generated by heating elements in the form of electrical resistance wires, which are arranged in thermally conductive radiators so that they deliver their heat to them. It has proven to be useful to arrange a plurality of radiators in a row to deliver the heat over a larger area on the slide rail. The slide rail thus extends over a plurality of radiators and thereby prevents impact edges are formed in the glued together veneer. So that the slide is not on the Adhesive sticks in the joints, the slide rail is provided with a non-stick coating. The task of the slide rail is to transport the heat in the glue and the adjacent joint area on the one hand, and on the other hand to keep the individual veneer pieces flat.
Dadurch, dass die Widerstandsdrähte ihre Wärme zunächst an die Heizkörper und dann an die Gleitschiene abgeben, ist nur eine indirekte Erwärmung der Gleitschiene möglich. Weiterhin ergibt sich aufgrund der Vielzahl von erforderlichen Heizkörpern eine aufwendige Konstruktion, die auch verhindert, dass die Gleitschiene ausreichend unterstützt wird, um den erforderlichen Druck auf die Furnierstücke auszuüben. Darüber hinaus stellen die bekannten Heizkörper relativ steife Elemente dar, welche eine flexible Anpassung der Gleitschiene an unterschiedliche Furnierdicken nur sehr schlecht ermöglichen.Due to the fact that the resistance wires first deliver their heat to the radiators and then to the slide rail, only indirect heating of the slide rail is possible. Furthermore, due to the large number of required radiators a complex construction, which also prevents the slide is sufficiently supported to exert the required pressure on the veneer pieces. In addition, the known radiators are relatively rigid elements, which allow flexible adaptation of the slide rail to different veneer thicknesses only very bad.

Eine weitere Furnierzusammensetzmaschine ist in der
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, die bekannte Furnierzusammensetzmaschine zu verbessern.Based on this, the object of the invention is to improve the known veneer splicing machine.
Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.
Durch die erfindungsgemäße Ausgestaltung wird die Wärme direkt in die Gleitschiene eingebracht, da das Heizelement in die Gleitschiene integriert ist. Hierdurch kann ein Wärmeübergang eingespart werden, so dass eine bessere Effizienz gewährleistet ist. Weiterhin können die Heizkörper vollständig entfallen, wodurch die Wärmeverluste erzeugenden Oberflächen verringert werden. Ein weiterer Vorteil besteht darin, dass die Gleitschiene unabhängig von den Heizkörperlängen an sehr vielen Stellen unterstützt werden kann. Die erfindungsgemäße Ausgestaltung führt auch dazu, dass die Gleitschiene flexibel ist und sich somit dem Furnier anpasst, während die bisher verwendeten Heizkörper steife Elemente bildeten und somit nur schlecht an unterschiedliche Furnierdicken und an den Anfang und das Ende der Furnierstücke angepasst werden konnten, was zu einem Versatz der Fuge führen konnte. Dadurch, dass die Gleitschiene mit einer in Längsrichtung verlaufenden Nut versehen ist, wird eine lagesichere Anordnung des Heizelementes gewährleistet. Außerdem gewährleistet der in der Nut der Gleitschiene angeordnete Einsatz aus Kupfer, Bronze oder einem anderen flexiblen und gut wärmeleitfähigen Werkstoff einen guten Wärmeübergang von dem Heizelement auf den Einsatz und von dort auf die Furnierstücke.The inventive design, the heat is introduced directly into the slide rail, since the heating element is integrated into the slide rail. This allows a heat transfer can be saved, so that a better efficiency is guaranteed. Furthermore, the radiators can be completely eliminated, whereby the heat loss generating surfaces are reduced. Another advantage is that the slide rail can be supported at many points regardless of the radiator lengths. The inventive design also means that the slide is flexible and thus adapts to the veneer, while the radiator previously used stiff elements formed and thus poorly adapted to different veneer thicknesses and at the beginning and end of the veneer pieces, resulting in a Could cause misalignment of the joint. Characterized in that the slide rail is provided with a groove extending in the longitudinal direction, a position-safe arrangement of the heating element is ensured. In addition, the arranged in the groove of the slide insert made of copper, bronze or other flexible and highly thermally conductive material ensures good heat transfer from the heating element to the insert and from there to the veneer pieces.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous developments emerge from the subclaims.
Gemäß einer vorteilhaften Weiterbildung ist das Heizelement als längliche dünne Heizpatrone ausgebildet. Solche Heizpatronen werden z. B. von der Fa. Hotest vertrieben.According to an advantageous embodiment, the heating element is designed as an elongated thin heating cartridge. Such cartridges are z. B. marketed by the company. Hotest.
Damit das Heizelement seine Heizleistung möglichst verlustfrei an die Gleitschiene abgibt, ist das Heizelement vorzugsweise kraftschlüssig in der Aufnahmenut gehalten, insbes. mittels eines wärmeleitfähigen Klebstoffs. Alternativ kann das Heizelement auch formschlüssig in der Aufnahmenut gehalten werden.Thus, the heating element dissipates its heating power lossless possible to the slide, the heating element is preferably held non-positively in the receiving groove, esp. By means of a thermally conductive adhesive. Alternatively, the heating element can also be held in a form-fitting manner in the receiving groove.
Nach einer vorteilhaften Ausführungsform ist die Gleitschiene in ihrer Längsrichtung flexibel ausgebildet. Somit wird eine Gleitschiene mit einem optimierten Querschnitt und einer optimalen Flexibilität geschaffen, deren geringes Widerstandsmoment durch viele Krafteinleitungspunkte eine sehr gute Anlage an die Furnieroberfläche ermöglicht. Damit ist es viel besser möglich, die Kanten der zu verleimenden Furnierstücke exakt bündig zueinander zu führen.According to an advantageous embodiment, the slide rail is flexible in its longitudinal direction. Thus, a slide rail is created with an optimized cross-section and optimum flexibility, the low moment of resistance by many force application points allows a very good investment in the veneer surface. This makes it much better possible to guide the edges of the veneer pieces to be glued exactly flush to one another.
Nach einer bevorzugten Ausgestaltung weist die Gleitschiene eine thermisch isolierende Abdeckung auf, welche den Einsatz zumindest an seinen Längskanten umgibt. Dies gewährleistet einen nur geringen Wärmeverlust an die Umgebung sowie die benachbarten Transportelemente für die Furnierstücke.According to a preferred embodiment, the slide rail on a thermally insulating cover, which surrounds the insert at least at its longitudinal edges. This ensures only a small heat loss to the environment and the adjacent transport elements for the veneer pieces.
Die Abdeckung kann die Gleitschiene jedoch auch auf drei Seiten umgeben. Dies ermöglicht es, Heiztemperaturen von über 200°C zu verwenden, ohne dass Transportelemente aus Kunststoff oder ähnlich empfindlichen Materialien, wie Kunststoffgliederketten oder Zahnriemen, negativ beeinflusst werden.However, the cover may also surround the slide on three sides. This makes it possible to use heating temperatures in excess of 200 ° C without adversely affecting transport elements made of plastic or similar sensitive materials, such as plastic link chains or toothed belts.
Die Verbindung der Gleitschiene mit der Abdeckung kann auf zwei Arten erfolgen. Gemäß der einen vorteilhaften Weiterbildung ist vorgesehen, dass der Einsatz über eine formschlüssige Verbindung mit der Abdeckung verbunden ist, insbes. über eine Schwalbenschwanzverbindung. Dies ermöglicht ein einfaches Anbringen der Gleitschiene an der Abdeckung.The connection of the slide with the cover can be done in two ways. According to an advantageous embodiment, it is provided that the insert is connected via a positive connection with the cover, esp. Via a dovetail connection. This allows easy attachment of the slide rail to the cover.
Gemäß einer alternativen Ausführungsform kann der Einsatz auch über eine kraftschlüssige Verbindung mit der Abdeckung verbunden sein, insbes. verschraubt oder verklebt sein.According to an alternative embodiment, the insert can also be connected to the cover via a frictional connection, in particular screwed or glued.
Um eine ausreichende Flexibilität der Gleitschiene sicherzustellen, kann vorteilhafterweise die Gleitschiene einen flachen Querschnitt aufweisen.In order to ensure sufficient flexibility of the slide, advantageously, the slide can have a flat cross-section.
In manchen Anwendungsfällen kann es vorteilhaft sein, wenn der Einsatz mit einem Ansatz versehen ist und die Aufnahmenut für das Heizelement zumindest teilweise in dem Ansatz ausgebildet ist.In some applications, it may be advantageous if the insert is provided with a lug and the receiving groove for the heating element is at least partially formed in the approach.
Das Heizelement kann nach einer vorteilhaften Ausgestaltzung auch über ein zusätzliches Halteelement in der Nut gehalten sein.The heating element may also be held in the groove via an additional holding element according to an advantageous embodiment.
Statt eine Heizpatrone zu verwenden, kann nach einer alternativen Ausführungsform das Heizelement auch als dünner Film mit Leiterbahnen als Widerstandsheizung ausgebildet und direkt auf die Gleitschiene aufgebracht sein.Instead of using a heating cartridge, according to an alternative embodiment, the heating element can also be designed as a thin film with conductor tracks as resistance heating and be applied directly to the slide rail.
