Description
Nachschnitteinrichtungen an Furnierbeschneidemaschinen sind bekannt. Es hat sich in der Praxis jedoch gezeigt, daß die Güte der Schnittfläche beim Nachschnitt bei den verschiedenen Furnierstärken ganz verschieden ist. Um eine gleichmäßig saubere Schnittfläche bei den verschiedensten Furnierstärken zu erhalten, ist es nötig, daß die Nachschnittbreite eingestellt werden kann. Um hierbei eine genaue Verschiebung des Messerträgers auch auf die Dauer zu erhalten, muß die Führung desselben nachstellbar sein.Recut devices on veneer trimmers are known. In practice, however, it has been shown that the quality of the cut surface during recut is very different for the different veneer thicknesses. To get an evenly clean To obtain a cut surface with the most varied of veneer thicknesses, it is necessary to that the re-cut width can be adjusted. To do this an exact shift To get the knife carrier in the long run, the guidance of the same must be adjustable be.
Die erfindungsgemäße Reguliervorrichtung .ist in der Zeichnung in einer beispielsweisen Ausführungsform veranschaulicht, und zwar ist Abb. i eine Seitenansicht nach I-I der Abb. 2 und Abb. 2 eine Schnittansicht nach II-11 der Abb. i. Die Reguliervorrichtung gemäß der Erfindung besteht im wesentlichen aus dem Messerträger i und dessen Führung, die aus zwei gegeneinander versetzten Keilflächen 2 besteht, die ihrerseits mit zwei auf der Innenseite des Führungsgehäuses 8 angeordneten und zueinander versetzten Keilflächen 9 zusammenarbeiten. In dem genannten Führungsgehäuse ist eine Welle io gelagert, auf der eine Exzenterscheibe 3 befestigt ist; die über einen Gleitkopf i i mit einem Winkelhebel 4 zusammenarbeitet, dessen freies Ende am Boden der Querverbindung 12 der beiden Keilführungen 2 angelenkt ist.The regulating device according to the invention .is in the drawing in of an exemplary embodiment, namely Fig. i is a Side view according to I-I of Fig. 2 and Fig. 2 is a sectional view according to II-11 of Fig.i. The regulating device according to the invention consists essentially of the knife carrier i and its guide, which consists of two mutually offset wedge surfaces 2, which in turn are arranged with two on the inside of the guide housing 8 and mutually offset wedge surfaces 9 work together. In the mentioned guide housing a shaft io is mounted on which an eccentric disk 3 is attached; the above a sliding head i i cooperates with an angle lever 4, the free end of which is hinged to the bottom of the cross connection 12 of the two wedge guides 2.
Soll der Messerträger i zwecks Einstellung oder Änderung der Breite des Furnierbeschnittes seitlich verschoben werden, dann werden durch Drehen der Exzenterscheibe 3 mittels des Handhebels 7 und das hierdurch bewirkte Verschwenken des Winkelhebels 4 die Keilflächen 2 auf den zugehörigen Keilflächen 9 in Richtung des Pfeiles a gehoben oder gesenkt, womit, bedingt durch das Zusammenwirken der genannten Keilflächen, eine Seitenverschiebung des Messerträgers einhergeht. Die erfindungsgemäße Vorrichtung ermöglicht somit durch größeres oder kleineres Verschwenken des Handhebels 7 eine größere oder kleinere seitliche Verschiebung des Messerträgers und somit eine leichte und genaue Einregulierung der Nachschnittbreite für die jeweils zu bearbeitenden Furniere.Should the knife carrier i for the purpose of setting or changing the width of the veneer trim are shifted laterally, then by turning the Eccentric disk 3 by means of the hand lever 7 and the pivoting effected thereby of the angle lever 4, the wedge surfaces 2 on the associated wedge surfaces 9 in the direction of the arrow a raised or lowered, with which, due to the interaction of the called wedge surfaces, a lateral displacement of the knife carrier is associated. the The device according to the invention is thus made possible by greater or lesser pivoting of the hand lever 7 a larger or smaller lateral displacement of the knife carrier and thus easy and precise adjustment of the re-cut width for each veneers to be processed.
Um die Keilflächen 2 gegeneinander einstellen und nachstellen zu können, ist an der die beiden Keilflächen verbindenden Querverbindung 12 ein Schraubbolzen 5 mit Stellschraube 13 vorgesehen, durch deren Betätigung die Keilflächen 2 der Höhe nach zueinander einreguliert werden können.In order to be able to set and readjust the wedge surfaces 2 against each other, is a screw bolt on the cross connection 12 connecting the two wedge surfaces 5 provided with adjusting screw 13, by actuating the wedge surfaces 2 of the Height can be adjusted according to each other.
