Description

Vorrichtung zum Anpressen von Werkstücken aus Holz an eine Führung mittels Saugluft Beim Bearbeiten von Werkstücken aus Holz, insbesondere auf bekannten Dicktenhobelmaschinen, entstehen häufig Beschädigungen besonders am Anfang und Ende des Werkstückes durch die Messerwelle, da das Werkstück nicht einwandfrei auf dem Werktisch der Maschine aufliegt, wodurch ein genaues Hobeln erschwert ist.Device for pressing workpieces made of wood against a guide by means of suction air When machining workpieces made of wood, especially on known ones Thickness planers, damage often occur, especially at the beginning and end of the workpiece through the knife shaft, as the workpiece is not properly on the The workbench of the machine rests on, which makes precise planing difficult.

Dieser Mangel soll gemäß der Erfindung dadurch behoben werden; daß zum Anpressen von Werkstücken an eine Führung mittels Saugluft, was bei Maschinen zur Bearbeitung von Glas, Metall o. dgl, bekannt ist, der Unterdruck zum Ansaugen des Werkstückes derart bemessen ist, daß das Werkstück während seiner Bearbeitung seiner Führung oder dem Werktisch der Maschine plan anliegt, der Vorschub dagegen nicht behindert ist.This deficiency should be remedied according to the invention; that for pressing workpieces against a guide by means of suction air, which is the case with machines for processing glass, metal or the like is known, the negative pressure for suction of the workpiece is dimensioned such that the workpiece during its machining its guide or the workbench of the machine lies flat, the feed against it is not disabled.

In der Zeichnung ist der Gegenstand der Erfindung in einem schematischen Schnitt beispielsweise dargestellt.In the drawing, the subject of the invention is in a schematic Section shown for example.

Die in bekannter Weise mit einem Werktisch i, einem Druckbalken 2 und einem Spanauswerfer 3 versehene Hobelmaschine ¢ weist die bekannten Gleitwalzen 5 und Vorschubwalzen 6 auf, durch die einerseits das Gleiten des Werkstückes 7 ermöglicht und anderseits dem Werkstück der notwendige Vorschub vermittelt wird.The in a known manner with a work table i, a pressure beam 2 and a planing machine provided with a chip ejector 3 has the known slide rollers 5 and feed rollers 6, through which on the one hand the sliding of the workpiece 7 is made possible and on the other hand the necessary feed is conveyed to the workpiece.

Oberhalb des Werktisches ist zwischen dem Druckbalken 2 und dem Spanauswerfer 3 die umlaufende Messerwelle 8 vorgesehen. Der Tisch i weist Bohrungen 9 auf, die in ein nach außen geschlossenes Gehäuse io münden, an dem eine Rohrleitung i i angeschlossen ist, die z'weckm'äßig mit der Spanabsaugeanlage für die Maschine in Verbindung steht.Above the work table is between the pressure beam 2 and the chip ejector 3 the rotating cutter shaft 8 is provided. The table i has holes 9 which open into an outwardly closed housing io, to which a pipeline i i is connected that is in connection with the chip extraction system for the machine.

Durch diese Spanabsaugeanlage wird in der Saugleitung i i und im Gehäuse i o ein Unterdruck erzeugt, der sich durch die Bohrungen 9 auf die Unterseite des Werkstückes 7 überträgt und dadurch das Werkstück derart ansaugt, daß unter allen Umständen ein gutes Anliegen des Werkstückes auf dein Werktisch erreicht wird und somit keine Vertiefungen oder sonstigen Beschädigungen, die durch ungenaues Aufliegen des Werkstückes auf dem Werktisch bedingt werden, eintreten können.This chip extraction system is i i in the suction line and in the housing i o creates a negative pressure, which is through the holes 9 on the underside of the Transferring workpiece 7 and thereby sucking the workpiece in such a way that among all Under certain circumstances, a good concern of the workpiece is achieved on your workbench and thus no depressions or other damage caused by inaccurate seating of the workpiece on the workbench can occur.

Selbstverständlich kann die Bauart der Maschine beliebig gewählt werden und ist der Erfindungsgedanke auch nicht nur an Hobelmaschinen gebunden, sondern könnte auch bei sonstigen Holz oder ähnliche Stoffe bearbeitenden Maschinen mit Werkstückvorschub verwendet werden.Of course, the design of the machine can be chosen as desired and the idea of the invention is not only tied to planing machines, but could also be used with other machines that process wood or similar materials Workpiece feed can be used.

Zweckmäßig wird man, was in der Zeichnung nicht dargestellt ist, unterhalb der Bohrungen einen oder mehrere Schieber anordnen, um je nach der Breite des zu bearbeitenden Werkstückes die Bohrungen abdecken zu können, die von dem Werkstück nicht bedeckt werden. Man könnte aber die Bohrungen auch konisch halten, um die frei liegenden Bohrungen durch ,einen leicht herausnehmbaren konischen Pfropfen aus Metall o. dgl. verschließen zu können.What is not shown in the drawing is expedient below of the holes to arrange one or more slides, depending on the width of the machining workpiece to be able to cover the bores made by the workpiece not be covered. But you could also keep the bores conical to the exposed holes through an easily removable conical plug made of metal o. The like. To be able to close.
