The workpiece W is reliably rolled by the rolling member 5 rotating in the clockwise direction of 3, and the abrasive is projected from above by the two projectors 4 in this state.

FIG. 5 shows the rolling member 5, FIG. 5 (A) is a vertical end view, and FIG. 5 (B) is a front view. The rolling member 5 includes a central axis that is rotatably supported by a bearing, left and right disks 7 through which the central axis passes through the center, and a workpiece W that is positioned on the tray member 6 in the polishing area 3. Two net members 8 that are positioned in parallel so as to be sandwiched between two directions, and a partition 9 that divides the polishing area 3 into three in the horizontal direction in accordance with the shape and size of the workpiece W. The workpieces W are stored one by one in the three divided areas as shown in FIG.
The rolling member 5 has a structure in which the central axis is driven independently by the drive motor 11 shown in FIG. 1 and rotates independently. The workpiece W is polished on the entire surface by the projector 4 while rolling in the polishing area 3. Sweeper is projected. Since the net member 8 is net-like and has a lot of gaps, the net member 8 suitably passes through the polishing material projected from the projector 4. It is desirable that these are composed entirely of metal like the tray member 6.

Then, the three workpieces W introduced from the insertion port 2 are placed on the tray member 6 in the scouring area 3 and scoured from above by the projector 4 while being rolled by the rolling member 5.

FIG. 9 shows the workpiece W rolled by the tray member 22 and the rolling member 23 in the polishing area 3. In order of (1), (2), (3), (4), and (5), the workpiece W continues to rotate reliably by being inclined on the net member 8 of the rolling member 5 on the tray member 22. .
The workpiece W is projected on the entire surface by the projector 4 while rolling in the polishing area 3. Since the net member 8 has many air gaps, the net member 8 is suitably transmitted through the polishing material projected from the projector 4.
When the polishing of the workpiece W is completed, as shown in FIG. 9 (6), the driving member 22 a rotates the tray member 22 about several tens of degrees in the clockwise direction around the pivot shaft at the upper right end. The workpiece W rolls down from the opening portion of the rolling member 5 in the lower right direction of (6) in FIG. 9 and moves to the next step.
In this way, when the polishing process for one workpiece W is completed, the next workpiece W is loaded from the loading port 2 and the same operation as described above is repeated.

FIG. 10 shows another embodiment of the rolling member 5 of the second embodiment described above, and this rolling member 30 is for processing a plate-like workpiece W.
This rolling member 30 has three sides closed and one side opened, and the cross section has a U-shape. The rolling member 30 is not rolled, but the rolling member 30 is rotated. As a result, the polishing material is uniformly projected on both sides of the plate-like workpiece W.

FIGS. 11 to 14 show a third embodiment of the shot blasting apparatus of the present invention. The shot blasting apparatus 31 includes a loading port 2 for loading a workpiece W and a workpiece W loaded for a certain period of time. A polishing area 3 on which the abrasive material is projected, two projectors 4 for projecting the abrasive material from above onto the abrasive area 3, and one workpiece W in the abrasive area 3 one by one A rolling member 32 that is partitioned and rolled, and a conveyor belt 33 that moves to place and rotate the rolling member 5 and the workpiece W.
