Description

[Detailed description of the invention] The present invention uses straight cylindrical or polygonal columnar wood materials with almost equal cross sections to control the centering of veneer lace in plywood production, so that the length in the fiber direction and the orientation of the fibers are uniform. The purpose of this invention is to obtain particles suitable for manufacturing particle plates with uniform fiber orientation.

To explain the device of the present invention with reference to the drawings of the embodiment, two rotating shafts 1 and 2 are arranged so that their axes are parallel to each other and almost coincide with the horizontal plane. 1 and 2 each have a plurality of plane bodies 3.3 A, 3 B...
...and plane barrels 4, 4 A, 4 B...
is installed with an appropriate small gap d.

One plane cylinder for each of the rotary shafts 1 and 2 is disposed opposite to each other, for example, plane bodies 3 and 4 or 3A and 4A, and the opposing plane bodies have substantially the same width.

In this embodiment, all the plane cylinders have the same width W, but the widths may be different for each opposing plane cylinder.

Each plane barrel has an outer periphery consisting of an outer edge E and an inner edge E', and the outer edge E of the outer periphery has a cutting edge width that is approximately equal to the width of the plane barrel, and has a cutting edge line. The swords are mounted so that the blades are parallel to the axis of the rotating shaft, and the same number of swords, in this embodiment, two swords 5 and 5A are mounted on each of these plane bodies.

When attaching these swords to the plane body, set the radius of the cutting edge circle of each sword to be the same, and set the cutting edge circle P of each sword attached to the rotating shaft 1 and the rotating shaft 2. The radius of the cutting edge circle or the distance between the two rotating axes is set so that the cutting edge circle P' drawn by the signature sword of each plane body intersects at the intersection points Q and Q'.

In addition, the relative position, or phase, of attaching the signature sword to each plane barrel is as follows: between opposing plane bodies and between adjacent plane bodies,
For example, between the opposing plane bodies 3 and 4, the two planes are set to be out of phase with each other.
As shown in figure A, the signature swords 5 and 5A attached to the plane body 3
If the positions of the blade tips are up and down, set the positions of the blade edges of the swords 5 and 5A attached to the opposing plane barrels 4 to the left and right, and between the adjacent plane bodies 3 and 3A. ,
As shown in Figures A and B in Figures 1 and 2, the plane body 3
The position of the signature sword on the plane body 3A and the position of the signature knife on the plane body 3A are set to be out of phase (60° phase shift in the embodiment).

The mounting position of the fishing force of the planer barrel 4A opposite to the planer barrel 3A is also set in correspondence with each other, as shown in FIGS. 1 and 2B.

As described above, each plane body and outer peripheral edge are composed of an outer edge E and an inner edge E', except for the rake surface 6' of the back blade 6, and the outer edge E is located at a position close to each fishing force 5, 5A. It is shaped like a part of a cylindrical surface with a radius slightly smaller than the radius of the cutting edge circles P and P', and the inner edge E' has a distance from the axis of both rotating shafts 1 and 2 to its periphery than that of the outer edge E. It is formed small.

In the opposing planer barrels attached to both rotating shafts 1 and 2, the fishing force and outer edge of one are relative to the inner edge of the other so that the fishing force and the outer edge do not come into contact with each other when the rotating shafts rotate. Also, the peripheral edge shape of the inner edge portion is formed.

In addition, the outer edge portions E of the plurality of planer barrels attached to the same rotating shaft are arranged so that the outer edge portion of any one of the planer barrels is always in contact with a part of the surface of the material to be processed. As shown in FIG. 1, the peripheral edge of the outer edge portion E has a shape that forms a perfect cylindrical surface when viewed from the axial direction of the rotating shaft on the same plane, and The outer edges E of the plural plane barrels form a V-shaped support surface that supports the material to be processed.

In this embodiment, the V-shaped support surface formed by the outer peripheral edge of the plane cylinder is formed by three plane cylinders, and these three plane cylinders are shown in FIG. If there is one group G, there is at least one group similar to this group (in the embodiment, it is composed of two groups G and G1).

) is attached to each rotating shaft 1 and 2, and has an axial dimension corresponding to the length of the material to be processed, and forms a stable support surface for the material to be processed.

In addition, as in this embodiment, the V
Instead of forming a letter-shaped support surface, it is also possible to selectively form an appropriate number of support surfaces, such as two or four.
In short, a V-shaped support surface is formed by an appropriate number of plane barrels, and the cutting edge circles of the opposing plane barrels intersect with each other.
Any configuration is sufficient as long as the opposing fishing force and outer edge of one side do not come into contact with the inner edge of the other plane barrel.

Although the drive devices for the rotating shafts 1 and 2 are not shown, the rotating shafts rotate inwardly at the same speed.

That is, as shown in FIGS. 1 and 2, the rotating shaft 1 is rotated clockwise and the rotating shaft 2 is rotated counterclockwise at the same speed.

Then, the material to be treated, such as a control center, is placed on the V-shaped supporting cylindrical surface formed by the outer peripheral edge of each plane barrel attached to each of the two rotating shafts, so that its axis is parallel to the axis of the rotating shaft. The material is placed so that it will look like this, and cutting is performed using its fishing force.

Since the device of the present invention is configured in this way, the material to be processed is supported by the V-shaped support surface formed by the outer peripheral edge of the planer barrel, and the rotation of the planer barrel causes the material to be placed on the surface. Since the cutting direction is inward at each part, the material to be processed is always cut in a stable state (the axis of the material to be processed is parallel to the axis of the rotating shaft), and the fishing force is Coupled with the configuration in which the cutting edge line is parallel to the axis of rotation, the cutting is always in the same direction as the fibers, and by setting the width of the fishing force, it is possible to obtain particles with a desired length in the fiber direction. This makes it possible to obtain particles suitable for producing particle boards with uniform fiber orientation.

In addition, the cross-cutting configuration of the cutting edge circles allows the entire amount of material to be processed to be processed, and furthermore, the cut pieces fall downward from the gap between the two plane barrels facing each other without scattering, and the cut pieces are removed. The device of the present invention has the advantage of being easy to collect, and the device of the present invention can effectively utilize waste materials such as restraints, and its effects are significant.
