In FIGS. 7 to 12, for example, two plate members 2 are placed on the table 16 of the first transfer device 12, and the first cylinder device 15 is extended. Then, the pressing plate 19 pushes the plate 2 laterally.

At this time, the microswitch 40 of the first intermittent mechanism 13 moves from the concave portion 42a to the next concave portion 42a,
The microswitch 41 is moved from the projection 42b to the next projection 42b.
, The actuators 40a and 41a each operate once to stop the extension of the first cylinder device 15.

When the first cutting section 14 is operated in this state, a part of the plate 2 is cut into one bar 4. When the compressed air is supplied from the compressed air supply source 68 when the solenoid valve 66 is switched to the raised position 66a shown in FIG.

Raise in the direction. When the dog 50a of the cutter mounting portion 50 operates the actuator 53a of the microswitch 53, the solenoid valve 66 is switched to the neutral position (not shown), and the ascent of the cutter 52 stops.

When the solenoid valve 66 is switched to the lowered position 66b, the compressed air enters the cylinder device 48 through the pipes 63 and 64, and pushes down the piston 58 to lower the cutter 52 in the direction of arrow B. And the bar 4 are cut.

After one cut, the dog 50 a of the cutter mounting portion 50 is moved to the actuator 5 of the microswitch 54.
When the valve 4a is operated, the solenoid valve 66 is switched to the raised position 66a, and the cutter 52 is immediately raised.

When the cutter 52 descends, the compressed air is supplied into the cylinder device 48 from two places of the pipes 63 and 64, so that a shear force twice as large as that in the case of one piston 58 is applied to the plate member 2. And the bar 4 can be easily cut.

When one bar 4 is cut from the plate 2,
Again, the first cylinder device 15 sends out the plate materials 2 at equal pitches p, and the first cutting unit 14 cuts the plate materials 2 one after another to process them into the equal-width bar 4. This is repeated until the bar 4 is obtained.

After being cut, the bar 4 is pushed out by the first transfer device 12 and moves on the table 26 of the second transfer device 22 as it is.

When all the cutting of the plate material 2 placed on the table 16 is completed, the push plate 19 is
The first cylinder device 15 contracts until it comes into contact with the third actuator 43a, so that the plate member 2 can be placed again.

, The actuators 40a and 41a each operate once to stop the extension of the first cylinder device 15. That is, in FIG. 11, the bar 4 is sent out by the pitch p.

When the second cutting section 24 is operated in this state, a part of the bar 4 is cut into the wood chip 3. The operation of the portions related to the second cutting portion 24, such as the solenoid valve 66, the cylinder device 48, and the cutter 52, is the same as that of the first cutting portion 14, and thus the same portions are denoted by the same reference numerals in the drawings. , The description of which is omitted.

When the wood chips 3 are cut from the bar 4,
Again, the second cylinder device 25 sends out the bars 4 at equal pitches p, and the second cutting unit 24 cuts the bars 4 one after another to process the wood chips 3 having the same width. This is repeated until the wood chips 3 are obtained.

After being cut, the wood chips 3 are pushed out by the second transfer device 22 and are collected by the collection box 71 down the slope 70.

When all the cutting of the bar 4 placed on the table 26 is completed, the second cylinder device 25 contracts, and the push plate 29 retreats to a position where the next bar 4 can be received. Is stopped until the next bar member 4 is supplied from the transfer device 12 of the second embodiment.

In this way, as shown in FIGS. 1 to 3, the board 2 is cut lengthwise and crosswise to produce a wood chip 3.
Alternatively, it is also possible to manufacture a polyhedral wood chip 3 such as a hexagonal prism as shown in FIG.

In the above processing, the cutter 52 is used for cutting,
Since the cutting is performed by the shearing force, the amount of chips is reduced, the yield of wood is improved, and a large amount of wood chips 3 can be manufactured.

In the above configuration, the second transfer device 22 must be stopped when the first transfer device 12 is operating, and when the second transfer device 22 is operating. The first transport device 12 must be stopped, but is not limited to such a configuration.
The first transfer device 12 and the second transfer device 22 are installed in series in the same direction.
A mechanism for rotating the direction of the bar 4 by 90 ° is provided between

4 also rotates in the direction of arrow D, and the surface 8 on the polishing side of the polishing means 80.
0a travels in the direction of arrow E. Along with this, the wood chip 3 is polished while rolling in the direction of arrow F, and is chamfered as shown in FIG. The rotation speed of the driving pulley 83 is, for example, 1500 rpm, and the polishing side surface 80a
Is restrained by the gantry 85. .

Since the surface 80a on the polishing side of the polishing means 80 is inclined, the wood chip 3 climbs the inclination while rolling, and eventually hits the corner 81a. Then wood chips 3
Is smoothly guided along the arc shape of the corner 81a, rises, returns in the direction of the arrow G, is polished by the polishing means 80 while rolling again, and climbs up the slope.
1 is efficiently circulated, and all the wood chips 3 are evenly polished and chamfered.

The wood chips 3 circulate while being polished as described above, so that each chip is uniformly polished and chamfered. Further, by reducing the amount of the wood chips 3 to be put into the frame portion 81 from the hopper 82, the wood chips 3 can be easily circulated in the frame portion 81.
It is possible to perform chamfering of uniform quality in a short time of about 3 to 3 minutes.

When the chamfering is sufficiently performed, as shown in FIG. 18, when the linear drive device 89 is operated to move the frame portion 81 in the direction of arrow H, for example, the wood chips 3 having been chamfered are collected. It falls into the box 91 and is collected. At this time, the other frame portion 91 is located directly above the polishing means 80, so that the wood chips 3 can be supplied from the hopper 82 and the above-described chamfering polishing can be performed.

When the chamfer is sufficiently performed, the frame 9
When 1 is moved in the direction of arrow I, the wood chips 3 that have been chamfered fall into another collection box 91 and are collected. By repeating these operations, the wood chips 3 can be chamfered efficiently.

By inserting a chamfered wood chip 3 of, for example, cypress into a pillow 9 as shown in FIG. 6, the head is not stuffy due to the effect of the cypress having excellent heat absorption and hygroscopicity. In addition, it can sleep in a cool state, and the effect of the aromatic substance released from the cypress (phytoncide effect) can provide hygiene effects such as antibacterial, anti-mite, deodorant and mental stability effects.
