Grinding device of glass plate

Abstract

A grinding device (1) of a glass plate comprises a linear conveyance unit (3) which linearly conveys the glass plate (2) along the X direction; a first grinding device is provided with grinding heads (5) and (6) for respectively grinding the two side edges (4a) and (4b) of the glass plate (2) linearly conveyed by the linear conveyance unit (3) extending along the X direction; and a second grinding device is adjacent to the first grinding device in the X direction and provided with movable grinding heads (9) and (10) for respectively grinding a front edge (7) and a rear edge (8) extending along the Y direction orthogonal with the X direction for the linear conveyance by the linear conveyance unit (3).

Description

technical field [0001] The present invention relates to a glass plate grinding machine for grinding the edges of glass plates such as glass plates for plasma displays (PDP), glass plates for liquid crystal displays (LCD), glass plates for solar cells, glass plates for furniture, glass plates for buildings, etc. cutting device. In addition, the present invention relates to a glass plate grinding device for grinding the edges of a glass plate and cutting the corners. In particular, the present invention relates to horizontally conveying a rectangular glass plate, and first simultaneously Grinding device for glass plate that grinds one side and then grinds the remaining opposite sides at the same time, and then cuts the corners of the front and rear corners. Background technique [0002] Patent Document 1: Japanese Patent Laid-Open No. 2000-233351 [0003] For example, in Patent Document 1, a glass plate grinding device is proposed, which grinds opposite two edges of the glas...

AI Technical Summary

Problems solved by technology

[0004] However, in the grinding apparatus of Patent Document 1, since the peripheral edge of the glass plate is ground while reciprocating the glass plate one by one, the glass plate cannot be supplied in a continuous flow operation, and continuous grinding cannot be performed. difficult to increase production

And in this grinding device, there will be a rotating device that will rotate the glass plate 90° between the first device and the second device, and a positioning device and a positioning space will be arranged so that the glass plate coming out of the rotating device is aligned with the second device. Corresponding to the second device, as a whole, the equipment space becomes larger, and the glass plate requires high positioning accuracy of the second device, which requires complicated operations and adjustments during operation
