DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timber processing apparatus for plane-cutting long wood for architectural use, particularly, long wood of a curved shape used for a purlin or a beam.

[0002]

2. Description of the Related Art In general, a purlin or beams of a wooden house are shown in FIG.
A long timber W as shown in FIG. On the curved surface of the long timber W, a bundle seat a for setting up a bundle column (not shown)
Is partially cut in a plane, and a mortise b for fitting a tenon of a bundle column is formed in the bundle seat a. Conventionally, these partial processes have been performed manually.

Conventionally, a technique of mechanically cutting the bundle seat a with a horizontal planar has also been tried. The horizontal planar used here has a plurality of rollers 7 as shown in FIG.
1, the long wood W is pressed against the platen 72 and sent out.
The long rotary wood 73 is used to partially cut the long lumber W on a plane.

[0004]

However, the manual cutting and drilling not only have poor machining efficiency, but also make the bundle seat a parallel to the core wire c of the long wood W and make the mortise b a right angle. However, there is a problem that it is difficult to process each of them, and the processing accuracy is reduced. Further, in the case of the horizontal planar, since the roller 71 presses the long wood W and sends it in an elastically deformed state, springback occurs in the long wood W or the bundle seat a is inclined with respect to the core wire c. There is a problem that it is processed in a state where it is not.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wood processing apparatus capable of efficiently and precisely cutting a long piece of bent wood with a flat surface.

[0006]

In order to solve the above-mentioned problems, a planar processing method according to a first aspect of the present invention does not apply an extra external force to a long piece of bent wood by using a small-sized gripping claw.
