る。(Prior Art) As a device for shaping bent glass such as automobile windshield, a press molding machine composed of upper and lower molds is arranged adjacent to a heating furnace, and a plate glass which is carried out from the heating furnace and is in a high temperature state is rolled. It has been known from the past that a conveyor conveys the material directly above the lower mold (ring mold) of the press molding machine, bends and molds the plate glass with a stopper and pusher at this position, and rapidly cools it if necessary. Has been.
(考案が解決しようとする課題) 上述した従来装置にあっては板ガラスを位置決めさせる
ため、ストッパ或いはプッシャが直接高温の板ガラスに
接触することとなる。(Problems to be Solved by the Invention) In the above-mentioned conventional apparatus, since the plate glass is positioned, the stopper or pusher comes into direct contact with the high temperature plate glass.
そして、ストッパ或いはプッシャは板ガラスに比べて低
温であるので、接触した部分にクラックが発生し、これ
が後に破損のきっかけや強度低下の原因にもなってい
る。Since the stopper or pusher has a lower temperature than that of the plate glass, a crack is generated at the contacted portion, which also causes damage later and lowers the strength.

As shown in FIG. 4 and FIG. 4 which is a view in the direction of arrow B in FIG. 3, a pair of brackets 10, 10 are fixed to a machine body of the molding machine 2, and a shaft 11 is interposed between the brackets 10, 10. A double rod type cylinder unit 12 is rotatably pivotally mounted, and a roller 16 is attached to a lower end of a piston rod 15 protruding from an upper surface of the cylinder unit 12, and the roller 16 is engaged with a cam hole 17 formed in the bracket 10. I am fit. Thus, when the position of the front end of the plate glass G is determined and the state shown in FIG. 3 is completed, air is supplied to the upper chamber of the cylinder unit 12 and the piston rods 12 and 15 are lowered. The roller 16 moves, and the cylinder unit 12 slightly rotates about the shaft 11 in the clockwise direction in FIG. As a result, as shown by the imaginary line in FIG. 3, the contact portion 14 moves down from the glass sheet G toward the front (to the right in the drawing) and moves downward, so that the front end portion of the glass sheet G is rubbed by the contact portion 14. Never.
