本発明は、ガラス板の面取装置に関し、詳しくはガラス
板の角部を円弧状に研削する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for chamfering a glass plate, and more particularly to a device for grinding corners of a glass plate into an arc shape.
従来より鏡板あるいはステレオパネル等の矩形状ガラス
板の角部を円弧状に研削する装置としては、（１）ガラ
ス板を台座に固定し研削具を首振り運動させて角部を研
削する装置、（２）所望曲率を有した倣い型を用い、こ
の倣い型に沿って研削具を動かし角部を研削する装置、
（３）作業者がガラス板を手に持ってシーミング用ベル
トにガラス板の角部を接触させながらガラス板を摺動さ
せ角部を研削する装置等が知られている。Conventionally, devices for grinding the corners of a rectangular glass plate such as a mirror plate or a stereo panel into an arc shape include (1) a device that fixes the glass plate to a pedestal and grinds the corners by swinging a grinding tool; (2) A device that uses a copying die with a desired curvature and grinds a corner by moving a grinding tool along the copying die;
(3) A device is known in which an operator holds a glass plate in his hand and slides the glass plate while bringing the corner of the glass plate into contact with a seaming belt to grind the corner.
しかしこれらの装置には、次の様な欠点が生じるもので
あった。However, these devices have the following drawbacks.
即ち（１）首振り運動させる装置においては、ガラス板
角部への研削具接触開始時と、接触解除時に凹凸状の段
付き部を生じ、均一な曲率を形成することが難しく、（
２）の倣い型を用いる装置にあっては、ガラス板のサイ

、研削具の運動が複雑となり機構上難しい、（３）人的
作業においては、個人差により角部の曲率形状が異なり
、しかも作業者が各ガラス板を手に持って作業する為に
危険を伴うものであった。That is, (1) in a device that makes swinging motion, an uneven stepped portion is created when the grinding tool starts contacting the corner of the glass plate and when the contact is released, making it difficult to form a uniform curvature;
In the case of equipment that uses a copying die (2), a copying die is required for each size of the glass plate, and the copying die must be replaced each time.Also, depending on the ratio of the long and short sides of the glass plate, grinding may be required. (3) In manual work, the curvature shape of the corner varies depending on individual differences, and the work is dangerous because the worker holds each glass plate in his hand. Met.
