Definitions

  • the invention relates to a device for producing wooden beams made of glued together wooden planks, with a lower support for laying 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.
  • the wooden planks to be glued together are placed on the support which runs in the horizontal direction and which generally consists of support blocks which are arranged parallel and at a distance from one another.
  • the rear abutment adjoining the support consists of abutment supports adjoining the support brackets and extending in the vertical direction.
  • 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.
  • the press spindles are then tightened from the support bracket to the support bracket, the wooden planks being hit firmly onto the support using a hammer, so that the wooden planks lie in one plane.
  • 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.
  • 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.
  • Two vertical pressure cylinders are advantageously arranged next to one another at a distance in the upper arm of the bridge.
  • the horizontal pressure cylinder is preferably arranged in a height-adjustable manner in the side arm of the bridge.
  • the bridge can preferably be moved step by step from the support bracket to the support bracket of the support.
  • 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.
  • the horizontal pressure cylinder is arranged in the side arm of the bridge in a carriage which is displaceably guided on the side arm.
  • 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.
  • 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.
  • 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.
  • the invention is exemplified in the drawing.
  • the drawing shows the device according to the invention in cross section.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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 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.
  • the L-shaped bridge 5 is moved to the first support bracket of the support 1.
  • the L-shaped bridge 5 is then gradually moved to the next support block of the support 1, where the wooden planks 14 are pressed together in the manner described and the next pressing device is attached.
  • 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.
  • 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.
  • 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.
