Description

Es ist bekannt, die Tischwalzen vom Bedienungsstand aus durch eine Steuerung entspre-, chend der jeweils zu hobelnden Holzart gemeinsam zu heben und zu senken, jedoch haben diese bekannten Einrichtungen den Nachteil, daß sie in der Bauart nicht einfach genug sind, so daß Betriebsstörungen eintreten können.It is known that the table rollers from the operator's station by a control corresponding, Depending on the type of wood to be planed, they can be raised and lowered together, however these known devices have the disadvantage that they are not simple in construction are enough so that malfunctions can occur.

Dieser Nachteil soll gemäß der Erfindung ίο dadurch behoben werden, daß die Tischwalzen auf Wellen gelagert sind, die beiderseits einen exzentrischen, im Maschinenständer gelagerten Lagerzapfen aufweisen, und daß an jeder der Wellen ein Hebel befestigt ist, die sämtlieh durch eine angelenkte Stellstange miteinander verbunden sind.This disadvantage is to be eliminated according to the invention ίο in that the table rollers are mounted on shafts, which are eccentric on both sides, mounted in the machine frame Have bearing journals, and that a lever is attached to each of the shafts, all of which are connected to one another by a hinged control rod.

In der Zeichnung ist eine beispielsweise Ausfuhrungsform des »Erfindangsgegenstandes, bei welcher die Tischwalzen in der Höhe ao verstellbar angeordnet sind und eine Vorrichtung vorgesehen ist, mittels welcher sie gemeinsam verstellt werden können, dargestellt. Es zeigen:The drawing shows an example of an embodiment of the »subject matter of the invention, in which the table rollers are arranged adjustable in height ao and a device is provided, by means of which they can be adjusted together, shown. Show it:

Abb. ι einen Längsschnitt durch eine Tisch- »5 walze undFig. Ι a longitudinal section through a table roller and

Abb. 2 einen Schnitt gemäß Linie I-I in. Abb. i.Fig. 2 shows a section along line I-I in. Fig.i.

Jede Tischwalze α ist mittels Kugellagern 6 auf einer Welle c gelagert. Diese Welle c weist an beiden Enden exzentrisch angedrehte Lagerzapfen d auf, welche im Maschinenständer e gelagert sind. Auf der Welle c sitzt ein Hebel f. Diese Hebel / sind an einer Zugstange g angelenkt, welche einen Griff h aufweist Um diese Zugstange g feststellen zu können, weist sie eine Anzahl Kerben/ auf, 1 und am Maschinenständer ist ein Bolzen k als Anschlag hierfür angeordnet.Each table roller α is mounted on a shaft c by means of ball bearings 6. This shaft c has eccentrically turned bearing journals d at both ends, which are mounted in the machine frame e. C on the shaft sits a lever f. These levers / are articulated g of a tie rod which has a handle h To g notice these tie rod it comprises a plurality of notches / on, 1 and the machine frame is a pin k as a stop arranged for this.

Diese Vorrichtung- ermöglicht, in einfacher Weise die Tischwalzen entsprechend den zu verarbeitenden Hölzern gleichzeitig um genau gleich viel in der Höhe zu verstellen. Dies geschieht durch Verschieben der Zugstange^, wodurch alle Wellen c um gleich viel verdreht werden. Da die Wellen c an den exzentrischen Lagerzapfen d gelagert sind, werden durch ihre Verdrehung ihre Achsen und damit die auf ihnen sitzenden Tischwalzen gehoben oder gesenkt.This device makes it possible, in a simple manner, to adjust the table rollers simultaneously by exactly the same amount in height, depending on the wood to be processed. This is done by moving the tie rod ^, whereby all shafts c are twisted by the same amount. Since the shafts c are mounted on the eccentric bearing journals d , their axes and thus the table rollers sitting on them are raised or lowered by their rotation.

Die Einrichtung gemäß der Erfindung könnte auch so ausgebildet werden, daß die gesamte Tischfiache oder wenigstens die zwischen den Tischwalzen liegenden Teile derselben parallel zu sich senkrecht verschiebbar gemacht wurden, wobei die Tischwalzen fest bleiben würden.The device according to the invention could also be designed so that the entire table area or at least the parts thereof lying between the table rollers parallel to itself were made vertically displaceable, with the table rollers fixed would stay.
