る。Next, the operation of the equipment configured as described above will be described. The abrasive grains are projected by driving the abrasive grain projection mechanism (1), and the vibrating conveyor (3) and the bucket conveyor (4) are driven to remove the foreign matter-containing abrasive grains discharged from the polishing machine (2). When the collected abrasive grains are sent to the separator (5), the collected abrasive grains are again supplied to the abrasive grain projection mechanism (1) while foreign substances such as sand are removed by the separator (5). In addition,
When a product is first cleaned, a relatively large amount of sand is mixed in the collected abrasive grains. Therefore, as described above, when a part of the collected abrasive grains sent to the separator (5) is guided to the belt conveyor (9) by the take-out pipe (7) and then carried out from the belt pulley (10) side (the 2), the abrasive grains in the collected abrasive grains are held by the magnetism of the belt pulley (10), and only the sand therein falls, and thereafter, the collected abrasive grains separate from the belt pulley (10) and become abrasive grains. Also fall, and the collected abrasive particles are separated into sand and abrasive particles. The separated abrasive grains are supplied to the abrasive grain projection mechanism (1) via the conduit (14) and are projected again, while the separated sand is charged into the hopper (12) and the weighing means (13) )), The input amount is measured successively. When the input amount gradually decreases and the input amount per unit time decreases to the set value set in the control device (17), sand is almost removed from the product. Become. When a predetermined time elapses after the amount of sand charged into the hopper (12) has decreased to the set value, the drive of the abrasive grain projection mechanism (1) is stopped by a command from the control device (17), and the polishing is completed. I do. After the completion of the cleaning, the opening / closing mechanism (15) is opened / closed to discharge the sand in the hopper (12), thereby completing one cycle.

However, the present invention is not limited to this. For example, as shown in FIG. A structure in which a cylindrical non-magnetic body (32) is rotatably provided outside of a semi-cylindrical magnetic body (31) having the same, and the collected abrasive grains are directly above the rotating non-magnetic body (32). From the position, sand on the right side of the bifurcated shoot (33),
The abrasive grains may be guided to the left side.

A weighing means, and a control device for comparing the measurement result of the weighing means with a preset set value and issuing a command to stop driving of the abrasive grain projecting mechanism after a lapse of a predetermined time from the time when they substantially match each other is provided. Therefore, the removal state of sand from the product is detected based on the weight of the sand in the collected abrasive grains, and the driving time of the abrasive grain projection mechanism can be automatically determined for each product. It has excellent effects such as eliminating the projection time and greatly shortening the abrasive grain projection time to increase productivity.
