Description

Detailed description of the invention (a) Industrial application field The present invention is prepared by cutting both edges in advance into a symmetrical scarf shape and applying an adhesive to one side of the board surface. A long product is obtained by overlapping the cross-cut parts of one piece of short plywood veneer, then shifting the overlapping parts in a step-like manner and pasting them in a predetermined number of layers. L
VL (laminated veneer lumber) or I
This invention relates to a veneer veneer cutting device, ie, a scarfing device, which is used in the manufacturing process of a veneer laminated material commonly known as VB (laminated veneer board).

Prior art A device for scarfing wood boards such as veneer veneer according to the prior art is disclosed in, for example, Japanese Patent No. 285888 (Japanese Patent Publication No. 36
-9948) As disclosed in the cutting device for wood fitting, etc., there is a roller conveyor that can brake and stop both ends of the workpiece separately at a fixed position, and a roller conveyor that is located between the roller conveyor and A saw machine that cuts and forms an inclined slope at an appropriate angle, a pressure plate that can press the workpiece together with the saw machine in between, a movable side of the pressure plate, and a movable side of the pressure plate and the saw machine. Two sets of pressure mechanisms that can be raised and lowered separately, and two sets of braking mechanisms that can brake and fix the operating positions of the two rough pressure mechanisms separately, are provided to intermittently convey, press, and cut workpieces. This scarf processing device was designed to repeatedly cut both edges of a wood board, such as a veneer board, twice in the front and back using a so-called saw machine.

(b) Problems to be Solved by the Invention As mentioned above, this type of scarf processing device according to the prior art only "processes the edges of a wood board such as a veneer veneer into two repeated cuts twice in the front and back." The process efficiency was low in the continuous production process because the scarf processing equipment was specialized for Since the cutting process could not be performed in the same process, it was necessary to prepare a rectangular wood board whose fiber direction had been changed and deposited according to the order of construction in advance, which hindered process efficiency and caused unnecessary waste. Therefore, in order to eliminate these difficulties, the present invention aims to ``arbitrarily change the fiber direction of the veneer veneer during the transfer process, and -
In addition, both edges were cut into contrasting slopes.

(G) Means for Solving the Problems The present invention provides a means for eliminating the difficulties in process efficiency and process operation of this type of scarf processing apparatus according to the above-mentioned prior art, by: a) fixing the veneer veneer with a pinch roller; b) The sides of the veneer veneer fed out by the pinch rollers are conveyed by a diagonal conveyor while making contact with a ruler; C) The diagonal conveyor A rectangular conversion conveyor is connected to the conveyor and a belt that can be raised and lowered is suspended between multiple rows of rollers, and d) a plywood veneer in the process of being transferred is The veneer veneer sheet is based on the following: The fiber direction of the veneer veneer can be arbitrarily changed to a perpendicular direction for the scarf machine that cuts the slope, and two turntable conveyors are installed in the front and back to make it possible to restore this direction. It is made using a board scarf processing device.

(Embodiment) The scarf processing device of the present invention will be described in the first to third embodiments.
As shown in Fig. 3, a veneer veneer 1 having a relatively short rectangular shape, for example, 1 m square, is fed out in the fiber direction by a pinch roller 2, and its side is conveyed to the ruler 4 side by a diagonal conveyor 3. Multiple rows of rollers 5 and their rollers 5 are arranged in parallel orthogonally to the transfer direction and continue to be transferred while being in contact with each other.
A conveying process is arranged so that the belt 6 is suspended between the rows of the fibers and is conveyed from the direction of the fibers to a rectangular conversion conveyor 7 in which a belt 6 is suspended between rows of the fibers. When the veneer veneer 1 passed on the right angle conversion conveyor 7 is a veneer veneer 1a with a structure that forms diagonal cuts with symmetrical slopes A and B on the front and back in the fiber direction, , this is transferred as it is from the first turntable conveyor 10a to the pressure conveyor 9 side where the scarf machine 8 is disposed, and is transferred by the belt conveyor 11. When the veneer veneer 1b is to be cut, the first turntable conveyor 10a is turned at a right angle and the belt conveyor 11 or Either one of the roller conveyors 12 is configured to be able to move up and down. Next, the first turntable conveyor 10
When the plywood A7 veneer 1a is transported by the belt conveyor 11 in the direction perpendicular to the fiber direction to form symmetrical slopes A and B on the front and back in the fiber direction, the scarf machine 8 and A second conveyor connected to the pressure conveyor 9
The turntable conveyor 10b also has bell 1 to conveyor 1.
The veneer veneer 1a is then transferred to the third side in a direction orthogonal to the fiber direction, and the fiber direction is once changed at right angles by the first turntable conveyor 10a, and the fiber direction is symmetrically transferred to the left and right of the fiber direction. When the veneer veneer 1b is formed with diagonal slopes C and D, the veneer veneer 1b is placed on the roller conveyor 14 side which has been once converted to a right angle to the second turntable conveyor 10b. After being handed over, it is turned at right angles to restore its original shape, and then transferred to a rectangular conversion conveyor 17 or a diagonal conveyor 19 equipped with a ruler 18, which is made up of multiple rows of rollers 15 and a belt 16 suspended between the rows so as to be able to move up and down. The veneer veneer 1b is transferred to a receiver, and although not shown in the drawings, the veneer veneer 1b is successively transferred to the next step of gluing, etc.

In the figure, 20a and 20b are cutting tools such as a circular saw or a cutter of the scarf machine 8, and 21 is a stopper.

Effects of the Invention As mentioned above, the present invention is capable of ``arbitrarily changing the fiber direction of the veneer veneer during the transportation process, and then cutting both edges of the veneer into contrasting slopes. This is a drawback of conventional scarf processing equipment, which is specialized only for cutting the edges of wood boards such as veneer veneers into two repeated cuts in the front and back twice. , it was possible to eliminate all serious drawbacks such as low process efficiency and the inability to arbitrarily apply contrasting bevel cutting to the front, back, left, and right edges of a square wooden board. The completion of the present invention has made significant progress in streamlining and streamlining the manufacturing process for laminated veneer materials, and has made it possible to insert cross punts with the fiber direction perpendicular to any lamination position, resulting in improved product quality. It has also become possible to use it more frequently.
