The panel (20) is provided with a table (2) in order from the supply position (L / D) on the starting end side of the forward stroke of the horizontal conveyor (23).
1) It is supplied to the upper part and fed into the arrangement range (L1) of the hollow cylindrical polishing body (24). In connection with this feeding operation, the pinion (28) at the lower end of the shaft (27) of the table (21)
Is engaged with the rack (36), the table (21) is rotated on the carriage (22), and the panel (20) positioned and mounted on the table (21) is rotated. The surface is polished by the polishing body (24). Then, it passes through the U-turn portion to enter the returning stroke, and the surface of the panel (20) is further polished by the hollow cylindrical polishing body (24) arranged in this returning stroke. In this way, the surface polishing of the panel (20)
Since it can be performed in both the forward stroke and the backward stroke of the horizontal conveyor (23), efficient surface polishing can be performed. Panel (20) after surface polishing is the horizontal conveyor (23)
Are sequentially taken out from the take-out position (T / O) at the end of the return stroke.
