Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von aus miteinander verleimten Holzbohlen bestehenden Holzträgern, mit einem unteren Auflager zum Auflegen der miteinander zu verleimenden Holzbohlen, einem daran anschließenden, das Auflager nach oben überragenden hinteren Widerlager für die Holzbohlen und mit Preßvorrichtungen, die mit ihrem einen Ende in das hinteree Widerlager und mit ihrem anderen Ende vorne in das Auflager einhängbar sind und eine parallel zum Auflager verlaufende Preßspindel zum Zusammenpressen und Zusammengepreßthalten der Holzbohlen haben.The invention relates to a device for producing wooden beams made of glued together wooden planks, with a lower support for placing the wooden planks to be glued together, a subsequent rear abutment for the wooden planks, which supports the upper support and with pressing devices having one end can be hooked into the rear abutment and with their other end at the front into the support and have a press spindle running parallel to the support for pressing and holding the wooden planks together.

Zur Herstellung eines Holzträgers werden die miteinander zu verleimenden Holzbohlen auf das in horizontaler Richtung verlaufende Auflager gelegt, das in der Regel aus parallel und im Abstand nebeneinander angeordneten Auflagerböcken besteht. üblicherweise besteht das sich an das Auflager anschließende hintere Widerlager aus an die Auflagerböcke anschließenden, in vertikaler Richtung verlaufenden Widerlagerstützen.To produce a wooden support, the wooden planks to be glued to one another are placed on the support running in the horizontal direction, which generally consists of support supports arranged parallel and spaced apart. Usually, the rear abutment adjoining the support consists of abutment supports adjoining the support brackets and extending in the vertical direction.

In diese Widerlagerstützen können nun Lochschienen der Preßvorrichtung mit einem Ende eingehängt werden. Die Preßspindel ist in einem Querriegel drehbar angeordnet, der mit seinen Enden in den vorderen Abschnitt der Lochschienen der Preßvorrichtungen und in entsprechende Ausnehmungen der Auflagerböcke einhängbar ist.In these abutment supports, perforated rails of the pressing device can now be hung at one end. The press spindle is rotatably arranged in a cross bar, the ends of which can be suspended in the front section of the perforated rails of the pressing devices and in corresponding recesses in the support blocks.

Zum Zusammenpressen der Holzbohlen werden dann von Auflagerbock zu Auflagerbock die Preßspindeln angezogen, wobei die Holzbohlen mit Hilfe eines Hammers jeweils fest auf das Auflager aufgeschlagen werden, so daß die Holzbohlen in einer Ebene liegen.To press the wooden planks together, the press spindles are then tightened from the support bracket to the support bracket, the wooden planks being firmly hit onto the support using a hammer, so that the wooden planks lie in one plane.

Nachteilig ist bei dieser bekannten Vorrichtung, daß das Ausrichten der Holzbohlen mit Hilfe des Hammers sehr mühsam ist und auch nicht sehr genau erfolgt. Nachteilig ist weiterhin, daß zum Zusammenpressen der Holzbohlen die Preßspindeln über einen relativ langen Weg betätigt werden müssen, so daß oftmals ein Umsetzen der Querriegel der Preßspindeln notwendig ist. Nachteilig ist außerdem, daß nur mit Mühe ein annähernd gleicher Preßdruck der einzelnen Preßvorrichtungen erzielt werden kann.The disadvantage of this known device is that the alignment of the wooden planks with the help of the hammer is very tedious and is also not very precise. Another disadvantage is that to press the wooden planks together, the press spindles have to be actuated over a relatively long way, so that it is often necessary to move the crossbars of the press spindles. Another disadvantage is that it is difficult to achieve an approximately equal pressing pressure of the individual pressing devices.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung der eingangs genannten Art derart weiterzubilden, daß auf einfache und kostengünstige Weise Holzträger mit hoher Genauigkeit hergestellt werden können.The object of the invention is to develop a device of the type mentioned at the outset in such a way that wooden beams can be produced with high accuracy in a simple and inexpensive manner.

Diese Aufgabe wird dadurch gelöst, daß oberhalb des Auflagers eine Brücke mit einem oberen Arm und einem seitlichen, im Abstand zum Widerlager neben dem Auflager verlaufenden Arm längs des Auflagers bzw. längs des Widerlagers verfahrbar angeordnet ist, daß im oberen Arm ein Vertikal-Druckzylinder mit Preßkolben angeordnet sind, deren Enden gelenkig mit einem Druckbalken zum Pressen der Holzbohlen auf das Auflager verbunden sind, und daß im seitlichen Arm ein Druckzylinder mit einem Preßkolben zum Pressen der Holzbohlen an das Widerlager angeordnet ist.This object is achieved in that a bridge with an upper arm and a lateral arm, which is spaced apart from the abutment next to the support and is movable along the support or along the abutment, is arranged above the support in that a vertical pressure cylinder in the upper arm are arranged with ram, the ends of which are articulated with a pressure beam for pressing the wooden planks onto the support, and that a pressure cylinder with a ram for pressing the wooden planks against the abutment is arranged in the lateral arm.

Vorteilhaft sind im oberen Arm der Brücke zwei Vertikal-Druckzylinder im Abstand nebeneinander angeordnet.Two vertical pressure cylinders are advantageously arranged next to one another at a distance in the upper arm of the bridge.

Der Horizontal-Druckzylinder ist vorzugsweise im seitlichen Arm der Brücke höhenverstellbar angeordnet.The horizontal pressure cylinder is preferably arranged in a height-adjustable manner in the side arm of the bridge.

Vorzugsweise ist die Brücke schrittweise von Auflagerbock zu Auflagerbock des Auflagers verfahrbar.The bridge can preferably be moved step by step from the support bracket to the support bracket of the support.

Bei einer bevorzugten Ausführungsform ist das untere Ende des seitlichen Arms der Brücke mit einer Rolle auf einer längs des unteren Auflagers verlaufenden Auflagerschiene verfahrbar. Vorteilhaft ist das seitliche Ende des oberen Arms der L-förmig ausgebildeten Brücke mit einer Rolle auf einer auf dem oberen Ende des hinteren Widerlagers angeordneten Lagerschiene verfahrbar.In a preferred embodiment, the lower end of the side arm of the bridge can be moved with a roller on a support rail running along the lower support. The lateral end of the upper arm of the L-shaped bridge can advantageously be moved with a roller on a bearing rail arranged on the upper end of the rear abutment.

Der Horizontal-Druckzylinder ist bei einer vorteilhaften Ausführungsform der Vorrichtung im seitlichen Arm der Brücke in einem Schlitten angeordnet, der auf dem seitlichen Arm verschiebbar geführt ist.In an advantageous embodiment of the device, the horizontal pressure cylinder is arranged in the side arm of the bridge in a carriage which is displaceably guided on the side arm.

Vorteilhaft ist am oberen Arm der Brücke ein Druckzylinder angeordnet, dessen Kolbenstange über einen Seilzug mit dem Schlitten verbunden ist.A pressure cylinder is advantageously arranged on the upper arm of the bridge, the piston rod of which is connected to the slide via a cable.

Vorzugsweise hat die Auflagerschiene eine seitliche Widerlagerfläche zum Abstützen des seitlichen Arms der Brücke entgegen der Wirkung des Horizontal-Druckzylinders. Die Auflagerschiene hat vorzugsweise eine untere Widerlagerfläche zum Abstützen des seitlichen Arms der Brücke entgegen der Wirkung des bzw. der Vertikal-Druckzylinder.The support rail preferably has a lateral abutment surface for supporting the lateral arm of the bridge against the action of the horizontal pressure cylinder. The support rail preferably has a lower abutment surface for supporting the side arm of the bridge against the action of the vertical pressure cylinder or cylinders.

Vorzugsweise hat die Lagerschiene gleichfalls eine seitliche Widerlagerfläche zum Abstützen des oberen Arms der Brücke entgegen der Wirkung des Horizontal-Druckzylinders. Vorzugsweise hat die Lagerschiene gleichfalls eine untere Widerlagerfläche zum Abstützen des oberen Arms der Brücke entgegen der Wirkung des bzw. der Vertiakal-Druckzylinder.Preferably, the bearing rail also has a lateral abutment surface for supporting the upper arm of the bridge against the action of the horizontal pressure cylinder. The bearing rail preferably also has a lower abutment surface for supporting the upper arm of the bridge against the action of the vertical pressure cylinder or cylinders.

Die Erfindung ist in der Zeichnung beispielhaft dargestellt. Die Zeichnung zeigt die erfindungsgemäße Vorrichtung im Querschnitt.The invention is exemplified in the drawing. The drawing shows the device according to the invention in cross section.

Nach der Zeichnung hat die erfindungsgemäße Vorrichtung ein unteres, in horizontaler Richtung verlaufendes Auflager 1, das aus parallel und im Abstand nebeneinander angeordneten Auflagerböcken besteht. Seitlich schließt sich an das Auflager 1 ein das Auflager nach oben überragendes, in vertikaler Richtung verlaufendes hinteres Widerlager 2 an, das im wesentlichen aus den Auflagerböcken des Auflagers 1 zugeordneten vertikalen Widerlagerstützen besteht.According to the drawing, the device according to the invention has a lower, extending in the horizontal direction support 1, which consists of parallel and spaced apart support blocks. Laterally adjoining the support 1 is a rear abutment 2 which projects above the support and extends in the vertical direction and which essentially consists of the vertical abutment supports assigned to the support blocks of the support 1.

Auf einer längs des Auflagers 1, im Abstand und parallel zum Auflager in horizontaler Richtung verlaufenden Auflagerschiene 3 ist das untere Ende eines seitlichen, in vertikaler Richtung verlaufenden Arms 4 einer L-förmigen Brücke 5 mit einer Rolle 6 verfahrbar.The lower end of a lateral arm 4 of an L-shaped bridge 5 with a roller 6 running along the support 1, at a distance and parallel to the support in the horizontal direction, can be moved with a roller 6.

Mit dem seitlichen Arm 4 der L-förmigen Brücke 5 ist ein im wesentlichen in horizontaler Richtung verlaufender oberer Arm 7 verbunden, dessen freies Ende mit einer Rolle 8 auf einer auf dem oberen Ende des Widerlagers 2 angeordneten, in horizontaler Richtung verlaufenden Lagerschiene 9 verfahrbar ist.With the side arm 4 of the L-shaped bridge 5, an essentially horizontal upper arm 7 is connected, the free end of which can be moved with a roller 8 on a bearing rail 9 arranged on the upper end of the abutment 2 and extending in the horizontal direction .

Wie die Zeichnung weiter zeigt, sind im oberen Arm 7 der L-förmigen Brücke 5 im Abstand nebeneinander zwei Vertikal-Druckzylinder 10 angeordnet, deren Preßkolben 11 in Richtung der mit 12 bezeichneten Pfeile bewegbar sind. Die Enden der Preßkolben 11 der Vertikal-Druckzylinder 10 sind gelenkig mit einem Druckbalken 13 verbunden, mit dem die auf dem Auflager 1 liegenden Holzbohlen 14 auf das Auflager gepreßt werden können.As the drawing further shows, two vertical pressure cylinders 10 are arranged in the upper arm 7 of the L-shaped bridge 5 at a distance from one another, the plunger 11 of which can be moved in the direction of the arrows 12. The ends of the plunger 11 of the vertical pressure cylinder 10 are pivotally connected to a pressure beam 13 with which the wooden planks 14 lying on the support 1 can be pressed onto the support.

Die Zeichnung zeigt weiter, daß im seitlichen Arm 4 der L-förmigen Brücke 5 ein Schlitten 15 in vertikaler Richtung verschiebbar geführt ist, in dem ein Horizontal-Druckzylinder 16 angeordnet ist, dessen Preßkolben 17 in der mit dem Pfeil 18 bezeichneten horizontalen Richtung bewegbar ist. Der Schlitten 15 ist über einen Seilzug 19 mit der Kolbenstange 20 eines am oberen Arm 7 angeordneten Druckzylinders 21 verbunden, so daß mit Hilfe dieses Druckzylinders der Horizonzal-Druckzylinder 16 in vertikaler Richtung am seitlichen Arm 4 der L-förmigen Brücke 5 nach oben und unten verschoben werden kann.The drawing further shows that in the side arm 4 of the L-shaped bridge 5, a carriage 15 is guided in the vertical direction, in which a horizontal pressure cylinder 16 is arranged, the plunger 17 of which is movable in the horizontal direction indicated by the arrow 18 . The carriage 15 is connected via a cable 19 to the piston rod 20 of a pressure cylinder 21 arranged on the upper arm 7, so that with the aid of this pressure cylinder the horizontal pressure cylinder 16 in the vertical direction on the side arm 4 of the L-shaped bridge 5 up and down can be moved.

Nachdem die miteinander zu verleimenden Holzbohlen 14 auf das Auflager 1 aufgelegt wurden, wird die L-förmige Brücke 5 zum ersten Auflagerbock des Auflagers 1 verfahren.After the wooden planks 14 to be glued together have been placed on the support 1, the L-shaped bridge 5 is moved to the first support bracket of the support 1.

Anschließend werden die Vertikal- und Horizontal-Druckzylinder 10 und 16 betätigt, so daß die Holzbohlen 14 fest auf das Auflager 1 und gegen das Widerlager 2 gepreßt werden. Nunmehr kann in einfacher Weise eine Preßvorrichtung angebracht werden, deren Preßspindel nur wenig betätigt werden muß, da durch den Horizontal-Druckzylinder 16 die vorgegebene Pressung der Holzbohlen 14 bereits erreicht ist.Then the vertical and horizontal pressure cylinders 10 and 16 are actuated, so that the wooden planks 14 are pressed firmly onto the support 1 and against the abutment 2. Now a press device can be attached in a simple manner, the press spindle of which only needs to be actuated a little, since the predetermined pressure of the wooden planks 14 has already been achieved by the horizontal pressure cylinder 16.

Nach Entlasten der Druckzylinder 10 und 16 wird dann die L-förmige Brücke 5 schrittweise zum nächsten Auflagerbock des Auflagers 1 verfahren, wo in der beschriebenen Weise die Holzbohlen 14 zusammengepreßt werden und die nächste Preßvorrichtung angebracht wird.After relieving the pressure cylinders 10 and 16, the L-shaped bridge 5 is then gradually moved to the next support bracket of the support 1, where the wooden planks 14 are pressed together in the manner described and the next pressing device is attached.

Das schrittweise Verfahren der L-förmigen Brücke 5 erfolgt vorteilhaft selbsttätig mit einem elektronisch gesteuerten Antriebsmotor. Da die Druckzylinder 10 und 16 vorzugsweise hydraulisch betätigt werden, kann in einfacher Weise das Anziehen der Preßspindeln mit einem hydraulischen Antriebsmotor erfolgen. Da außerdem die Druckkraft der Hydraulikzylinder auf vorgegebene Werte eingestellt werden kann, kann so auf einfache Weise kostengünstig ein sehr genauer, gerader Holzträger hergestellt werden.The step-by-step movement of the L-shaped bridge 5 is advantageously carried out automatically with an electronically controlled drive motor. Since the pressure cylinders 10 and 16 are preferably operated hydraulically, the press spindles can be easily tightened with a hydraulic drive motor. In addition, since the pressure force of the hydraulic cylinders can be set to predetermined values, a very precise, straight wooden beam can be produced in a simple and inexpensive manner.

Ist der auf dem Auflager 1 aufliegende Holzträger zusammengepreßt und sind alle Preßvorrichtungen angebracht, so kann in bekannter Weise auf diesen Holzträger unter Zwischenlage von Distanzhölzern eine weitere Lage von Holzbohlen 14 aufgelegt und in der beschriebenen Weise zusammengepreßt werden, wobei jedoch der Horizontal-Druckzylinder 16 mit Hilfe des Druckzylinders 21 in die entsprechende Position gebracht werden muß.If the wooden support resting on the support 1 is pressed together and all the pressing devices are attached, a further layer of wooden planks 14 can be placed on this wooden support with interposed spacers and pressed together in the manner described, but with the horizontal pressure cylinder 16 With the help of the pressure cylinder 21 must be brought into the appropriate position.

Wie die Zeichnung weiter zeigt, hat die Auflagerschiene 3 eine seitliche Widerlagerfläche 24 zum Abstützen des seitlichen Arms 4 der L-förmigen Brücke 5 entgegen der Wirkung des Horizontal-Druckzylinders 16 und eine untere Widerlagerfläche 25 zum Abstützen des seitlichen Arms der Brücke entgegen der Wirkung des bzw. der Vertikal-Druckzylinder 10.As the drawing further shows, the support rail 3 has a lateral abutment surface 24 for supporting the lateral arm 4 of the L-shaped bridge 5 against the action of the horizontal pressure cylinder 16 and a lower abutment surface 25 for supporting the lateral arm of the bridge against the action of the or the vertical printing cylinder 10.

Die Zeichnung zeigt weiterhin, daß die Lagerschiene 9 gleichfalls eine seitliche Widerlagerfläche 23 zum Abstützen des oberen Arms 7 der L-förmigen Brücke 5 entgegen der Wirkung des Horizontal-Druckzylinders 16 und eine untere Widerlagerfläche 23 zum Abstützen des oberen Arms der Brücke entgegen der Wirkung der Vertikal-Druckzylinder 10 hat.The drawing also shows that the bearing rail 9 also has a lateral abutment surface 23 for supporting the upper arm 7 of the L-shaped bridge 5 against the action of the horizontal pressure cylinder 16 and a lower abutment surface 23 for supporting the upper arm of the bridge against the action of the Vertical printing cylinder 10 has.
