The tip of the rod 16 is inserted into the lower side of the rod 24 at a position above the rear half of the rod 24 and protrudes in a direction perpendicular to the rod 24. do.

Since the present invention has such a structure, the present invention is implemented.The case of processing bamboo nails is described with reference to the drawings.
4, 24', 24''... are inserted from the lower surface side of the barge restraining plate 29, respectively, and inserted into the lower surfaces of the barge holding plate 26 and the bar tip end restraining plate 6, and when their tips come into contact with the barge positioning plate 22, the barb 24, 24', 24''... are pressed from above by the pressing force of the pressing spring 27 and the pressing spring 8 applied from above each of the rod holding plate 26 and the rod tip end holding plate 6, and are further pressed against the tip of the rod holding rod 16. presses the legs 24, 24', 24'', etc. laterally against the inner surface 25 side by the constant attraction force of the spring 18, so the bars 2
4, 24', 24''... are securely pressed and fixed from above and from the sides. In this state, move table 1
When you move the
The tips of the bamboo nails 4" are brought into contact with the circular saw 23 installed diagonally upward one after another, and the upper half of the tips are shaved off to form the pointed surface of the bamboo nail shown in FIG. 4. Next, further When the movable table 1 is moved toward the front, the rods 24, 24', 24''... will sequentially enter the lower side of the hook plate 10, and the rods 24, 24', 2 will be removed by the cutting circular saw 21.
4"... are each cut to a predetermined size of the bamboo nail to form the rear end surface of the bamboo nail shown in FIG. 4.
4', 24''... are completely cut off, when the movable table 1 is moved in the direction opposite to the front side, the tip side of the hook plate 10 sequentially enters the upper side of the bars 24, 24', 24''... as described above. , the bars 24, 24', 24'', 24..., which are in contact with the side surface of the bar 24 located at the innermost position, try to return with the return of the movable platform 1, and are scraped off by the tip of the hook plate 10. Falling all at once to the bottom,
It becomes possible to take it out of the machine. Further, the size of the sharp tip surface A can be freely adjusted by adjusting the position of the barb positioning plate 22, and the cutting dimension can be adjusted freely by adjusting the position of the circular saw mounting table 20. Therefore, when this invention is implemented, many bamboo nails are sharpened and cut to size almost at the same time and are automatically discharged outside the machine, making it extremely efficient.Moreover, it is possible to obtain products of stable quality and a wide variety of products. This is a device that has the effect of being able to respond appropriately to orders for dimensions.
