Thus, by removing the rough stones inside with the polishing mechanism section 150 at the A position, there is no risk of the rough stones cracking. The rough stones can be polished as described above.

As a method of taking out the rough stones, the polishing mechanism 150 is set to the A position, the lid 162 is removed, and then the polishing mechanism 150 is rotated to the C position to remove the rough stones. It is also possible to drop and discharge. In this case, the stopper portion 130 is attached to the locking portion 156c.
Since the polishing mechanism section 150 is fixed by being inserted into the above, safety can be maintained. Further, when the roughing stones are discharged with the polishing mechanism section 150 at the C position, the protective plate portion 176 is provided, so that the apparatus can be protected even if the rough stones fall.

In the rough stone polishing apparatus S3 of this embodiment, since the rotation of the polishing mechanism section 150 is performed by the rotating mechanism section 110 having the hydraulic cylinder 112 and the link mechanism, the polishing mechanism section 150 can be easily rotated. This can be ensured, and the overall size of the device can be reduced. Further, in the above embodiment, the stopper portion 130 and the locking portion 156 are provided.

The small gemstone can be uniformly introduced, and the large gemstone, the medium gemstone, and the small gemstone can be processed as a whole. In addition, in the "taiko-shaped" type of FIGS. 16 (b) and 16 (c), as shown in FIGS. 18 (b) and 18 (c), a large gemstone is put in the center, and the bottom and the shallow part are placed. Since medium and small balls can be put in, it is possible to polish the large gemstone from both sides,
Side surface processing can be performed faster.

Next, in the "cone" type shown in FIG. 17A, the diameter of the rough stone to be charged is changed according to the diameter of the drum body. That is, as shown in FIG. 19 (a), by placing a large gemstone at the bottom of a large diameter and arranging a medium gemstone or a small gemstone at a middle position or a shallow portion,
The peripheral speed of the large diameter part of the drum body is large, and the peripheral speed becomes smaller as the diameter becomes smaller.Thus, due to the difference in the peripheral speed of the drum body, the processing time for the large stones and the medium stones is equal. can do.

The "cone type" shown in FIG. 17 (b)
Type, the "cone type" shown in FIG. 17 (a) above
Contrary to the above, by inserting a rough stone with a small diameter into the bottom, and by throwing a large ball with a larger diameter closer to the lid, similar to the principle of the “corn type” in FIG.
