Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing thread-like wood chips from wood.

[0002]

2. Description of the Related Art Up to now, wood chips have been generated in the wood manufacturing process, but they have only been finely crushed to be used as livestock feed or, at best, waste.

On the other hand, the applicant of the present invention has invented a mat for growing lawns and has already applied for it to the government office. However, in this mat, a large amount of thin thread-like wood chips is often used. .

Further, since thread-like wood chips have a cushioning property, they can be used for pillows and the like.

In order to produce such thread-like wood chips,
For example, in JP-A-60-101002, there is a surrounding
Install a rotating disk with a cutting blade in an oblique direction to the rotation axis.
Wearing and cutting the surface of the wood while rotating the rotating shaft
A method for manufacturing thread-like wood chips by the method is disclosed.
JP-A-54-149997 and JP-A-62-2027.
No. 02 publications each have a cutting blade around the outside.
The rotating blade is formed in a spiral shape and fixed to the rotating shaft,
Yarn produced by cutting the surface of wood while rotating the rolling axis.
A method of manufacturing shaped wood chips is disclosed. But Naga
In these filamentous wood scrap manufacturing methods,
It is fixed in the direction, or the rotary blade is formed in a spiral shape.
Therefore, it is necessary to make a special device . Ie example
Rotation with existing cutting blades, such as a rotary saw
For the method of manufacturing filamentous wood waste using a disc, see
Not presented so far .

[0006]

DISCLOSURE OF THE INVENTION The present invention has a conventional cutting blade, such as a rotary saw, for cutting thread-like wood chips.
It is an object of the present invention to provide a method capable of being automatically manufactured by using a rotating disk .

[0007]

In order to solve the above-mentioned problems, the structure of the method of the present invention has a cutting blade on the periphery.
Rotate by fixing the rotating disc in a state orthogonal to the rotation axis.
While rotating the shaft, reciprocate it or twist it.
Filiform by cutting the surface of wood while moving
It consists of a wood chip manufacturing method .

[0008]

When an electric saw such as a tip saw cutter is pressed against wood as in the original use and then cut, only saw dust is generated and no filamentous wood chips are generated.

However, as shown in FIG. 1 (a), when the electric saw 1 moves along the surface of the wooden piece 3 while cutting the surface of the wooden piece 3 by rotation, the surface of the wooden piece 3 is cut by rotation and Since the portion to be cut is also moved by the movement, the object to be cut is in a continuous state with the movement, as shown in FIG.

This is nothing but thread-like wood chips.

The present invention uses the above method based on such a basic principle.

Namely, the method, FIG. 2 (a), (b)
As shown in Fig. 2 , the disk saw should be fixed and rotated at right angles to the rotation axis, and reciprocate as shown in Fig. 2 (a) or twist as shown in Fig. 2 (b). Thus, rotation and movement of the disk saw itself are formed (the reciprocating motion in FIG. 2 (a) is an oblique direction with respect to the axis, but the same direction as the axis is also possible). .

[0013]

EXAMPLE FIG. 3 (a) shows the above-mentioned embodiment, in which four tip saw cutters similar to those of the first embodiment are fixed to the rotary shaft 2 via the pressing spacer 21 in a direction orthogonal to the rotary shaft 2. .

Then, the rotary shaft 2 is rotated by an electric motor for driving a normal tip saw cutter, and
When the device itself including the drive motor has a width of 10 cm along the reciprocating table and the rotary shaft 2 is axially reciprocated along the surface of the wood 3, a filamentous wood waste having a length of 10 cm is obtained. I was able to.

The embodiment is characterized in that the length of the generated thread-like wood chips can be adjusted by freely selecting the length of the reciprocating movement.

[0016]

As described above, according to the present invention, the existing
It is possible to automatically and easily manufacture filamentous wood chips by using a tool such as a rotary saw .

This makes it possible to manufacture mats and other pillows using thread-like wood chips, so the significance of the present invention is extremely important.
