Reference numerals 70 and 71 indicate upper and lower surface cutting blades that are provided vertically and oppositely at intervals corresponding to the wall thickness for forming the bamboo piece 1b on the base 56, and when the bamboo piece 1b passes through these, the upper and lower surfaces of the bamboo piece 1b are cut. It is cut and molded to a certain thickness.

The side cutting blades 68 and 69 and the upper and lower cutting blades 70 and 71
may be provided facing each other horizontally or vertically at the same position, but it is preferable to shift them back and forth in order to reduce the resistance during cutting.

72.73 is a suppression roller rotatably provided behind the cutting blades 68, 69 on the first side and the cutting blades 70.71 on the upper and lower surfaces, and is constantly biased against the base 56 by springs 74.75, 6
This is to prevent the bamboo piece 1b from being pressed or bent when cutting the bamboo piece 1b with 9,70.71.

The disposable chopstick forming mechanism F cuts the top and bottom surfaces of the bamboo piece 1C' formed by the bamboo piece forming mechanism E into a single row of semicylindrical holes to form the original shape of disposable chopsticks.

76 is a frustum for cutting the top surface, 77 is a frustum for cutting the bottom surface,
Both the frustum 76.
The frustum 76, 77, on which the upper blade body 78 and the lower blade body 79 are provided, has one end rotatably supported and is always biased inwardly 111i by a spring 80, 81. The upper blade body 78 and the lower blade body 79 have two semicircular blade bodies 78a and 79a arranged side by side as shown in FIG. 8, with the upper blade body 78 facing downward and the lower blade body 79 facing downward. When the bamboo piece 1C passes through this part, the upper blade 78 cuts the upper surface, and the lower blade 79 cuts the lower surface into a single row of hooks.

82.83 is a semicircular indexing cam rotatably provided on the frustum 76.77 so that it is always restored to the position shown in the figure by the spring 90.91, and when the bamboo piece 1C passes through this, The cams 82, 83 come into contact with the truncated cones 76, 77, and the frustums 80.
81, raise x=-'h, and let the bamboo piece 1C escape from hitting the upper and lower blade bodies 78 and 79, and remove the head 2 of the disposable chopsticks.
The bamboo piece 1C is rotated by the resistance of the bamboo piece 1C, and when it comes to a flat surface, it is pushed by the springs 80 and 81 and the truncated cone 76 and 71j are restored, and the bamboo piece 1C is cut and plucked.

84.85 is a support 86.8 connected to the connecting rod 67.
It is pivoted to the supports 86 and 87 with the locking pawl provided at 7, and can be rotated in a certain direction, but cannot be rotated in the other direction because it is locked with a stopper, so it always returns to the position shown in the figure. Spring 88.
89, and reciprocates by the reciprocating mechanism 58.

Next, the effect will be explained.

The bamboo tubes 1a to be divided are placed on the storage shelf 18 of the material supply device B without being separated. Since the storage shelf 18 is inclined, the bamboo tube 1a tries to shift and fall, but it is stopped by the stepped portion 18aK and does not fall (FIG. 4A).

Therefore, when the conveyance table 25 of the bamboo feeding device 22 is moved back, the retainer 23 pushes up the roller 21 pivotally supported on the actuating plate 24, moves the actuating plate 24 upward, and the bamboo tube that has been caught and pulled on the stepped portion 18a is moved upward. Since the bamboo tube 1a is pushed up to release the lock, the bamboo tube slides down along the slope of the storage shelf 18 and falls onto the receiving frame 31 (FIG. 4B).

, When the bamboo tube 1a falls onto the receiving frame 31, when the transport platform 25 is moved forward, the control plate 33 (((receiving frame 30.3)
1 moves forward while holding the bamboo tube 1a against the spring 361 (Fig. 4A). At this time, the actuating plate 24
) Since the bond with Kaneko 23 is released, it moves down and restores itself. Therefore, the bamboo tube 1a also sequentially rolls on the stepped portion 18at, completing preparations for the next fall (FIG. 4A).

When the bamboo tube 1a is moved between the dividing blade 13 of the bamboo splitting device and the pressing table 14, the pressing table 14 by the cylinder 17 moves forward and presses the bamboo tube 1a against the dividing blade 13. (3rd
figure). At this time, the control plate 33 is pushed forward by the cylinder 34, and the spring 36 releases the support frames 30, 31Fi from holding the opening bamboo tube 1a, and the conveyor table 25 is moved backward to return to its original position, and the above-mentioned operation is repeated.

The bamboo tube 1a pushed off by the split blade 13 is
The bamboo piece alignment mechanism C is inserted between the outer cylinder 36 and the inner cylinder 37 from between each of the blade bodies 13a and 13a (FIG. 5A). Since the distance between the outer cylinder 36 and the inner cylinder 37 is only slightly wider than the thickness of the bamboo piece 1b, the divided bamboo pieces 1b may overlap between the outer cylinder 36 and the inner cylinder 37, or the front and back may overlap. They are arranged in an annular shape around the outer periphery of the inner cylinder 37 with the inner surface facing inward, without being turned over (FIG. 5A).

(16) Therefore, when the inner cylinder 37 is rotated counterclockwise by the cylinder 44, the bamboo piece 1b is stopped by the stopper piece 41, and the discharge passage 3
Arrange them from 8 and discharge them. At the same time as this, cylinder 4
4, the bamboo piece extrusion rod 39 is also moved forward, and the aligned bamboo pieces 1b are pushed out and moved on the movable table 45 1 of the bamboo piece supply mechanism (FIG. 5B). At this time, the movable table 45 is moved downward, and a step is formed between it and the fixed table 48, and at that step, the bamboo piece 1
Since bσ is locked, the bamboo piece 1b pushed out by the bamboo piece extrusion rod 39 is always placed on the movable table 45. Therefore, the cylinder 54 extends the scraper 53 to a position 1 beyond the movable base 45 as shown in FIG. 5B, and the cylinder 46 moves the movable base 45 upward to a position horizontal to the fixed base 48. Then, when the scraper 53 is returned to its original position, the bamboo piece 1b on the scraper 53 movable base 45 is hooked onto the fixed base 45.
8 (Fig. 5C). At this time, the first one of the aligned bamboo pieces 1b is the base 56 of the bamboo piece forming mechanism E.
It is located in the upper passage.

Therefore, when the movable rod 57 is moved forward by the reciprocating mechanism 58, only the bamboo piece 1b at the tip of the movable rod 57 is pushed out and the base 57 is pushed out.
6. Move the upper passage (Fig. 6).

When pushed and moved on the base 56 by the movable rod 57, the bamboo piece 1b is cut into the side cutting blades 68 and 69 of the bamboo piece forming mechanism E.
and passes through the upper and lower cutting blades 70 and 71. During this passage, the bamboo piece 1b is cut on both sides and the upper and lower surfaces, and is formed into a bamboo piece 1C having a constant width and a constant thickness (FIG. 6).

Next, when the bamboo piece 1C passes through the locking claws 84 and 85 of the disposable chopstick forming mechanism F, it is pushed and retracted against the springs 88 and 89, allowing the bamboo piece 1C to pass, but after passing the springs 88 .8
It is restored at 9 and acts to prevent rotation in other directions.

Therefore, when the bamboo piece 1C formed by the bamboo piece forming mechanism E is further pushed and moved by the movable rod 57, the bamboo piece 1C passes through the locking claw 84.

It is moved by the movable rod 57 up to this point.

Then, the bamboo piece 1C is caught and pulled by the locking claw 84 (FIG. 7A), and when it is moved forward by this movement, the upper blade body 78
As a result, the upper surface of the bamboo piece 1C is cut into a row of semicylindrical holes as shown in FIG. 8A.

At this time, the bamboo piece 1c comes into contact with the cam 82 and lifts up the frustum 76 against the spring 80, so the upper blade 78 does not work, and the cam 82 rotates due to the resistance of the bamboo piece 1C and turns into a flat surface. Kuruto Hasjo 8
When pressed at 0, the frustum 76 is restored and the upper blade body 78 works, so
While the frustum 76 is lifted by the cam "B2", the cutting
The remaining head 2 of disposable chopsticks is cut as shown in the first drawing.

Next, after cutting with the upper blade 78, the bamboo piece 1d passes through the next locking claw 85 and the rear part of the bamboo piece 1d is stopped by the locking claw 85 (
7B), when it is moved further forward, its lower surface is cut into a row of semicylindrical holes by the lower blade 79, leaving only the head 2, as with the upper blade 78. Figure 01 No. 8
As shown in Figure B) and Figure 1E, the original shape 1e of disposable chopsticks has formed and rusted.

This original shape 1e was cut into a tapered tip using a special machine9.
As shown in Figure 1F, disposable chopsticks 1 are completed.

As described above, according to the present invention, the original shape of disposable chopsticks is automatically formed from a bamboo tube, which is highly productive.
It requires less manpower, is efficient, and economical (19), and disposable chopsticks can be provided at low cost.
