Description
Die Erfindung bezieht sich auf eine Schleifmaschine für Platten, insbesondere Holzplatten, mit wenigstens einer Bandschleifeinheit, die aus einem über Walzen geführten Endlos-Schleifband und aus einer Gegendruckwalze besteht, deren Drehachse quer zur Bewegungsrichtung der zu schleifenden Platten verlaufen, von denen eine der beiden einander gegenüberliegenden Walzen in Richtung auf die andere bewegbar ist und die Arbeitsflächen der Walzen aus Stahl bestehen. Schleifmaschinen dieser Art sind bekannt (DT-AS 1 211 966, Fig. 3; DT-PS 1 677 135, Fig. 1). Hierbei ist es gleichgültig, ob die Gegendruckwalze oder die der Gegendruckwalze gegenüberliegende, mit weiteren Walzen das Schleifband führende Walzen durch einen Kraftspeicher beeinflusst wird.The invention relates to a grinding machine for plates, in particular wooden plates, with at least one belt grinding unit, which consists of an endless grinding belt guided over rollers and a counter-pressure roller, the axis of rotation of which runs transversely to the direction of movement of the plates to be ground, one of which is mutually exclusive opposite rollers is movable in the direction of the other and the working surfaces of the rollers are made of steel. Grinding machines of this type are known (DT-AS 1 211 966, Fig. 3; DT-PS 1 677 135, Fig. 1). It does not matter whether the counter-pressure roller or the rollers which are opposite the counter-pressure roller and which lead the grinding belt with additional rollers is influenced by an energy store.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, dass die Gegendruckwalze eine mit ringartigen Vorsprüngen ausgebildete Arbeitsfläche aufweist. Erreicht wird dadurch, dass diese Arbeitsfläche im wesentlichen nur noch auf die erhöhten Stellen in der zu schleifenden Platte drückt sobald de durch einen Kraftspeicher erzeugte Druckkraft ausgeübt wird. Gleichzeitig wird die Druckverteilung der Gegendruckwalze und damit auch der Platte vergleichmäßigt. Zweckmäßiger ist es, anstelle von ringartigen Vorsprüngen ein Flachgewinde einzusetzen, wobei sich ein 3-gängiges Flachgewinde am besten bewährt hat. Das Flachgewinde bewirkt beimThis object is achieved according to the invention in that the counter-pressure roller has a working surface formed with ring-like projections. What is achieved is that this work surface essentially only presses on the raised points in the plate to be ground as soon as the pressure force generated by an energy storage device is exerted. At the same time, the pressure distribution of the counter-pressure roller and thus also of the plate is evened out. It is more expedient to use a flat thread instead of ring-like projections, a 3-start flat thread having proven to be the best. The flat thread causes the

Im Falle des Ausführungsbeispieles ist angenommen, dass die Gegendruckwalze 1 mit Achsstummeln 2 an Bügeln, Hebelarmen od. dgl. 3 und 4 durch zwei Kraftspeicher, wie Pneumatikzylinder 5 und 6 beeinflußbar ist, wobei Justierschrauben 7 und 8 auf Lagern 9 bzw. 10 der Walze 11 vorgesehen sind, um den Maximalausschlag gegenüber den Lagern der der Gegendruckwalze 1 gegenüberliegenden Walze 11 festlegen zu können, die mit zwei weiteren Walzen 12 und 13 dem Führen eines Schleifbandes 14 dienen. Die zu schleifende Platte 15 wird zwischen der Gegendruckwalze 1 und dem Schleifband 14 meist in horizontaler Richtung bewegt.In the case of the exemplary embodiment, it is assumed that the counterpressure roller 1 with stub axles 2 on brackets, lever arms or the like 3 and 4 can be influenced by two energy stores, such as pneumatic cylinders 5 and 6, with adjusting screws 7 and 8 on bearings 9 and 10 of the roller 11 are provided in order to be able to determine the maximum deflection with respect to the bearings of the roller 11 opposite the counterpressure roller 1, which are used to guide a grinding belt 14 with two further rollers 12 and 13. The plate 15 to be ground is usually moved in the horizontal direction between the counter-pressure roller 1 and the grinding belt 14.
