  Next, an example of a preferred embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a tapered inner hopper, which drops and delivers a hard small spherical body, which is an object to be processed, downward. Reference numeral 2 denotes an additional hopper that is flange-connected to the upper portion of the tapered inner hopper 1 and is provided when the amount of small spherical bodies to be processed is large.

  A conical 3 is connected to the outlet of the tapered inner hopper 1 described above. The presence of the conical 3 makes it possible to limit and adjust the material level, pressure, and supply speed in the pipe member 4 when a small spherical body is delivered to the pipe member 4 described later.

  The opening of the upper surface of the pipe member 4 is fitted to the outlet of the conical 3. The small spherical bodies delivered from the conical 3 are sequentially accommodated in the pipe member 4. A gate 6 is formed in a part of the lower surface opening of the pipe member 4, and the size of the gate 6 is such that substantially upper half of the target small spherical body 5 can pass through.

  On the other hand, reference numeral 7 in the figure denotes a base, and a flat dish-like recessed portion 8 is formed on the upper surface of the base 7. In the recess 8 is provided a rotating disk 10 connected to the shaft 9 of the drive motor. Here, by using a stepping motor as the drive motor, it is possible to adjust the rotation speed and rotation angle of the rotary disk 10, and accordingly, the conveyance speed and the angle with respect to the conveyance time can be arbitrarily set and adjusted. .

  The above-described rotating disk 10 has a disk shape, and a tapered surface 11 is formed on the entire circumference from the upper surface to the side surface. The tapered surface 11 is for receiving the small spherical body 5 provided from the gate 6, and receives the lower half of the small spherical body 5 between the tapered surface 11 and the opening inner edge of the recessed portion 8. In other words, the small spherical body 5 is received in a state of protruding. In order to correspond to the position of the upper half or the lower half of the small spherical body 5, an angle of 45 degrees may be taken with a straight line connecting the center point of the small spherical body 5 and the surfaces of the rotary disk 10 and the base 7. Since it is desirable, in this embodiment, the angle of the tapered surface 11 is also 45 degrees with respect to the upper surface.

  The clearance between the tapered surface 11 of the rotating disk 10 and the inner edge of the opening of the recessed portion 8 is formed by receiving a lower half of the small spherical body 5 and forming a ring-like groove as a feed path for the received small spherical body 5. Become.
