Vertical guide rods 23, 23 are mounted between the two 22, a support body 24 is engaged with the guide rods 23, 23, and a nut member 25 of the support body 24 is connected to a motor 26.
The support body 24 is moved up and down by being screwed into a screw shaft 27 which is rotated by the motor 26.

By the way, a pair of the above-mentioned supports 24 are provided in a direction orthogonal to the conveying direction of the glass plate, that is, in the left-right direction of FIG. 3, and a frame frame 29 is attached between the pair of supports 24 via a horizontal shaft 28. Further, a motor 30 for rotating the horizontal shaft 28 to swing the frame 29 is attached to one of the supports 24, and a loading / delivery mechanism 32 provided in the frame 29 is operated for the other support 24. A motor 31 is attached.

As shown in FIGS. 3 and 5, the take-in / delivery mechanism 32 has a roller 34 fitted on a shaft 33 rotated by a motor 31, and a cylinder 35 is actuated on a frame frame 29 at a position facing the roller 34. Is provided with a shaft 36 that moves up and down, and a roller 37 that is in contact with the roller 34 is attached to the lower end of the shaft 36. The bent glass plate is sandwiched between the rollers 34 and 37, and the bent glass plate is taken into the cleaning station S2. Further, the cleaned bent glass plate is sent to the receiving station S3.

Further, in the frame 29, a take-in / delivery mechanism 32 is provided.
A receiving roll 39 that supports the lower surface of the bent glass that has passed through the intake / delivery mechanism 32 is provided on the downstream side, and a plurality of rotary cleaning jigs 40 are arranged above the receiving roll 39.

As shown in FIG. 6, the rotary cleaning jig 40 has a shaft 4 which is rotated by a motor 41 on a frame 29.
2 is inserted, and a sponge 43 or a brush that comes into contact with the upper surface of the glass plate is attached to the lower end of the shaft 42 via a plate 44. Then, as shown in FIG. 7, the shaft 42 of each rotary cleaning jig 40 is arranged substantially along the direction L2 orthogonal to the conveying direction L1 of the bent glass.

Further, each shaft 42 is urged downward by a spring 45 so as to be able to cope with a glass plate having a large curved shape, the lower limit of movement is restricted by a stopper 46, and a belt 47 adjoins the upstream side. Rotary cleaning jig 40
Power is transmitted to the rotary cleaning jig 40 on the downstream side.

Here, the adjacent rotary cleaning jigs 40 alternately hang the surface tooth belts on the belts 47 so that the rotation directions thereof are opposite to each other, and the sponge 43 and the plate 44 are shown in FIG.
As shown in FIG. 5, the shape is non-circular in plan view, specifically, the shape of a triangular top is circular, and a part of the rotational orbit thereof overlaps the rotational orbit of the adjacent rotary cleaning jig. By doing so, even if the rotary cleaning jigs 40 are arranged in a row and the width is narrowed, the glass plate can be cleaned without any gap.

Further, the shaft 42 of each rotary cleaning jig 40 is hollow, and the cleaning liquid is supplied to the surface of the glass plate through the shaft 42 so that the cleaning liquid can be evenly distributed even on a curved glass plate.

A method of cleaning a bent glass plate by the cleaning apparatus having the above-described structure will be described with reference to FIGS.

As shown in FIG. 8, the bent glass sheet G is horizontally conveyed by the conveyor belt 2 for conveyance at the transfer station S1. At this time, the presser roll 5 stands by upward, and the frame 29 is in the vertical state.

Thereafter, as the bent glass sheet G is horizontally conveyed by the conveyor belt 2 for conveyance, as shown in FIG. 9, the frame 29 is moved up by the drive of the motor 26, and the upper portion is driven by the motor 30 to deliver the upper part to the transfer station. The lower part is swung toward the receiving station S3 side on the S1 side, and in this state, the leading end of the bent glass plate G is caught between the rollers 34 and 37 of the feeding mechanism 32, and the bent glass plate G is washed by driving the motor 31. Take in the station S2.

The rollers 34 of the take-in / delivery mechanism 32,
As shown in FIG. 10 by the rotation of 37, the bent glass sheet G is received between the roll 39 and the rotary cleaning jig 43, and the rotation of the rotary cleaning jig 43 causes the glass sheet G to pass through the shaft 42.
The surface is cleaned while supplying the cleaning liquid. Since this cleaning is performed while feeding the glass plate G, it is performed while swinging the frame 29 so that an excessive force does not act on a part of the glass plate G. That is, when cleaning the middle point of the glass plate G in the transport direction, the frame 29 swings back to the vertical position so that the glass plate G becomes horizontal as shown in FIG.

Thereafter, as shown in FIG. 12, as the glass plate G is washed, the frame 29 swings the upper part to the receiving station S3 side and the lower part to the delivering station S1 side,
Receiving station S with glass plate G kept in a substantially horizontal state
3 is sent onto the conveyor belt 12.

[0021]

As described above, according to the present invention,
Since a cleaning jig is provided on the frame frame that can be moved up and down while swinging around a horizontal axis that is orthogonal to the direction in which the bent glass plate is conveyed, cleaning can be performed following the shape of the glass plate. It doesn't crack or break during washing,
Can be cleaned efficiently.

Further, since each rotary cleaning jig can be vertically moved independently, it is possible to sufficiently cope with a bent glass plate having a complicated shape.

Further, the width of the cleaning jig is narrowed by making the shape of the rotating cleaning jig non-circular in plan view, and by making a part of the rotation track thereof overlap with the rotation track of the adjacent rotating cleaning jig. Therefore, the area occupied by the entire device can be reduced.

Further, since the cleaning liquid is supplied through the rotary shaft of the rotary cleaning jig, a sufficient amount of cleaning liquid can be supplied between the cleaning jig and the glass plate regardless of the shape of the bent glass plate. You can
