To polish the glass plate 16 one after another. But,
Thereafter, the glass plate 16 attached to the upper surface plate 18 suspended through the next carriage 10 is simultaneously polished and transported to perform polishing, and the plurality of rear upper surface plates 18 are also subsequently polished. Finish.

The carriage 10 that has passed through the plurality of polishing machines 3 and has been polished and stopped before the movable support 33 is moved forward or manually to the traveling rails 7 ′ and 7 ′ of the movable support 33 manually or automatically. When the tilting cylinder 39 of the tilting means 32 is operated while the movable support 33 is stopped, the arm 37 is rotated about the shaft shaft 35 as the rod 38 is lowered, but the movable support fixed to the tip of the arm 37 is fixed. The body 33 also rotates following, and the upper surface plate 18 mounted on the traveling rails 7 ′ and 7 ′ via the carriage 10 also follows, and the glass plate 1 adsorbed to the pressure plate 17 of the upper surface plate 18.
6 also becomes an oblique state and shows the figure within the visual observation of the operator. In this way, when the tilting means for rotating the upper surface plate suspended from the movable support is provided, the glass plate can be attached to and detached from the upper surface plate safely and reliably in the tilted state. The purpose can be achieved.

While the state is maintained, the glass plate 16 that has finished the polishing finish is removed and a new glass plate is attached, and then the end of the movable support 33 is moved to the end of the track support 9 by the backward movement of the tilt cylinder 39. The upper surface plate 18 that is in series in the vicinity of the vehicle 10 and is suspended from the carriage 10 is manually moved forward to the predetermined position of the traveling rails 7 and 7 and connected to the transport carrier 21 at the predetermined position. The above operation is repeated after connection.
