処理に移ることができる。 In the normal stopped state, this barrel has one polishing tank 2 located directly above the discharge part 11, and the next polishing tank 2 located at its input port 2', as shown in FIG.
is located at the installation position of the hopper 15. Then, when a predetermined amount of a mixture of unprocessed material and abrasive material is charged from the hopper 15 and the fixed position stop device 12 is activated, the polishing tank 2 that has finished containing the material is moved by the aforementioned action of the position detection plate 23. It stops at the discharge position, and at the same time, the next polishing tank 2 reaches the loading position of the hopper 15 and automatically stops, so material can be supplied to the polishing tank 2. After intermittently driving the barrel in this way and supplying material to all polishing tanks 2, the air cylinder C5 is operated to release the clutch 24 connected to the geared motor M2 , and then the main motor When the motor M 1 is started, the motor M 1 continues its rotation for the time set by the timer, that is, the time required for grinding, and then automatically stops. Note that each polishing tank 2 revolves around the main shaft due to the rotation of the main shaft 1, and at the same time, the rotating shaft 4 is also driven via the rotational transmission mechanism 5, so that it rotates on its own axis. The stop position of the polishing tank 2 by the main motor M1 is not constant, but is stopped at an arbitrary position. When the fixed position stop device 12 is operated again as described above after the polishing tank 2 is stopped, the polishing tank 2 which has started rotating
When the first one of them reaches directly above the discharge section 11, the position detection plate 23 and the proximity switch S1 are engaged and automatically stopped at a predetermined position as described above. Next, when the push button switch PB 1 in the operation circuit E 1 of the bottom cover 8 is pressed, the solenoid valve SOLo and the cylinder Co are activated, and the inverted U-shaped rod 21 is lowered, and the contact piece at the lower end of the rod 21 is lowered. 21' pushes down the switching lever LS'n of the limit switch LSn at the tip of the arm 22, which has reached a predetermined position together with the polishing tank 2 by stopping at the fixed position, and the switching operation of the switch LSn switches the path of the solenoid valve SOLn. Then, from the original rotary joint Ro to the supply pipe Pb and the supply/discharge pipe
Pa, cylinder Cn through rotary joint Rn
Pressure fluid flows into the lower part of the cylinder Cn and is discharged from the upper part of the cylinder Cn, so the elevating rod 9 fitted into the cylinder Cn rises and the bottom cover 8 opens the discharge port 6. Therefore, the mixture in the polishing tank 2 is discharged from the discharge section 11 to the outside of the system through the outlet pipe 7 at the center of the rotating shaft 4. When push button switch PB 2 in operating circuit E 1 is pressed after discharging the material in the tank, the solenoid
SOLo is deenergized, the valve is switched, the rod 21 rises together with the piston Co' in the cylinder Co, and the switching lever pressed by the contact piece 21'
Since LS' is opened, limit switch LSn and solenoid valve SOLn are returned to their positions, and the inflow path of pressure fluid from supply/discharge pipe P is switched, and the cylinder
The elevator rod 9 is lowered in Cn, and the bottom cover 8 closes the outlet 6. After completing the material discharge operation in the first tank in this way, when the fixed position stop device 12 is operated again, the next polishing tank 2 reaches the discharge position.
Since the empty polishing tank 2 that has finished discharging comes to the loading position, it is possible to discharge it on one side and supply material with the other.Finally, the polishing tank 2 that has finished discharging is moved to the loading position and material can be supplied. By doing so, it is possible to move on to the next grinding process.

The fluid pressure switching device 10, which connects the upper end of the rod 9 and urges it downward, is provided with a rotary joint Rn, so that it reliably maintains the sealed state of the bottom cover 8. At the same time, the convex portion 8' on the back surface of the bottom cover 8 that fits into the discharge port 6 is caused by the flowing workpiece and abrasive material colliding with the lifting rod 9 and the bottom cover 8 during the polishing process. This prevents the displacement of the pressure contact position of the bottom cover 8 that may occur, and when closing the discharge port 6, it is first inserted into the discharge port 6 to guide the lowering of the lifting rod 9 and the bottom cover 8, so that it is always in a predetermined position. Crimp the bottom cover 8.

る。 As described above, a discharge port is provided at the bottom of each polishing tank that rotates and revolves around the main axis, and the discharge port is fitted into the back surface of the bottom cover that is crimped to the bottom of the polishing tank to open and close the discharge port. According to the present invention, the bottom cover is opened and closed by the operation of a lifting rod connected to a fluid pressure switching device equipped with a rotary joint and raised and lowered in a timely manner. The discharge operation is performed quickly, and the bottom cover is prevented from shifting during the polishing process, and the close contact with the bottom of the polishing tank is reliably maintained, so that the polishing liquid etc. can be prevented from leaking from the discharge port. In addition, the bottom cover above is
By fitting the convex portion on the back surface with the discharge port, the barrel is always pressed against the bottom of the polishing tank at a predetermined position, so this type of barrel has the advantage of being safe and easy to operate.
