A stopper is provided to prevent the above a from the machine frame.
An electric motor for rotating the screw is provided, which is fixed and screwed in the rotating direction to the feed screw in the direction, and is stopped by a proximity switch between the machine base and the stopper, and the tip edge of the plate glass is fixed and screwed in the rotation direction. An automatic feeding device is provided with an air nozzle for detecting the starting edge of the side surface of a plate glass before polishing, and a signal from the nozzle starts the electric motor, and the automatic feeding device detects the contact of the polishing machine at the starting edge and the terminal edge of the side surface of the plate glass. The purpose is to prevent over-polishing due to overpressure at the beginning and end of contact.

よびその反対方向に摺動させることができる。To explain an embodiment of the present invention shown in the drawings, a machine base 2 that is slidable in the direction of arrow a is pressed against the machine frame 1 by a pressing device 3 using an air cylinder in the same direction a, and the rear part of the machine base 2 is pressed in the same direction a.
Press the tips of the poles 1 to 4 screwed into the legs 2' and 2' against the stopper 5, screw the stopper 5 into the feed screw 6 provided on the machine frame 1 in the direction of arrow a, and then press the stopper 5. The stopper 5 can be slid in the direction of the arrow a and the opposite direction by fixing it in the rotating direction and rotating the screw punch 6 in the forward and reverse directions by the forward and reverse deceleration motor 7.

び固定ナツト４′を操作して調節することができる。As shown in FIG. 3, the stopper 5 has a horizontal metal plate 8 protruding from it, and the metal plate 8 is provided on the outer surface of the fork 2', 2'.
A proximity switch 9 is installed facing the bolt 4, and when the tip of the bolt 4 is pressed against the stopper 5 by the force of the pressing device 3, there is a certain gap t, and the same gap t is used to operate the bolt 4 and the fixing nut 4'. and can be adjusted.

機台２には板ガラス側面回転研磨機１０を設け、同機１
０の先端に設けた回転研磨盤１１を矢印ａと直角方向（

る。A plate glass side rotary polishing machine 10 is installed on the machine base 2, and the machine 1
Rotate the rotary polishing disk 11 installed at the tip of 0 in the direction perpendicular to arrow a (
The glass plate 12 is brought into contact with the side surface of the glass plate 12 moving in the direction indicated by the arrow.

矢印す方向に移動する板ガラス１２の先端縁は空気ノズ
ル１３によって検出されその電気信号によって上記電動
機７を始動し、螺杵６を正転して機台２を矢印ａ方向に
摺動させる。The leading edge of the glass plate 12 moving in the direction indicated by the arrow is detected by the air nozzle 13, and the electrical signal is used to start the electric motor 7, which rotates the screw punch 6 in the normal direction to slide the machine base 2 in the direction indicated by the arrow a.

このノズル１３の位置は上記研磨盤１１による上記板ガ
ラス１２の側面始端部の研磨前に同板ガラス１２の先端
縁を検出する位置であってその位置は第５図に示される
。The nozzle 13 is located at a position where the leading edge of the glass plate 12 is detected before the starting end of the side surface of the glass plate 12 is polished by the polishing disk 11, and this position is shown in FIG.

尚図中１４で示すものは研磨機１０の原動機、１５はス
トッパー５に設けた回動防止２股、１６は同２股１５．
１５が摺動自在に挟持するストッパー回動防止ガイドで
ある。In the figure, 14 indicates the prime mover of the polishing machine 10, 15 indicates two rotation prevention prongs provided on the stopper 5, and 16 indicates the two prongs 15.
15 is a stopper rotation prevention guide which is slidably held.

従って機枠１に設けたコンベヤによって矢印す方向に移
動する板ガラス１２の先端縁を空気ノズル１３で検出し
これを電気信号に変えて減速電動機７を始動させると螺
杵６が正転しストッパー５を矢印ａ方向に摺動させ研磨
盤１１を第５図実線位置から仮想線位置に移動させる。Therefore, when the air nozzle 13 detects the leading edge of the glass plate 12 moving in the direction of the arrow by the conveyor provided in the machine frame 1 and converts this into an electric signal to start the deceleration motor 7, the screw punch 6 rotates in the normal direction and the stopper 5 is slid in the direction of arrow a to move the polishing disk 11 from the solid line position in FIG. 5 to the imaginary line position.

その際同研磨盤１１が板ガラス１２の側面始端部に当接
すると同研磨盤１１の矢印ａ方向への移動は停止するが
ストッパー５は依然螺杵６の回動によって矢印ａ方向に
移動するから間隙ｔが拡大しその拡大によって近接スイ
ッチ９が動作し減速電動機７および螺杵６の回動を停止
しストッパー５を停止するからその停止位置においてボ
ルト４が同ストッパー５に圧接し研磨盤１１の矢印ａ方
向への研磨移動を停止することができる。At this time, when the polishing disk 11 comes into contact with the starting end of the side surface of the plate glass 12, the movement of the polishing disk 11 in the direction of the arrow a is stopped, but the stopper 5 is still moved in the direction of the arrow a by the rotation of the screw punch 6. As the gap t expands, the proximity switch 9 operates to stop the rotation of the deceleration motor 7 and screw punch 6, and stop the stopper 5. At that stop position, the bolt 4 comes into pressure contact with the stopper 5, and the polishing plate 11 is stopped. Polishing movement in the direction of arrow a can be stopped.

そしてその状態のまま板ガラス１２の側面は終端部まで
均一に研磨される。Then, in this state, the side surface of the glass plate 12 is uniformly polished up to the end portion.

従来エヤシリンダー等によって研磨盤を板ガラスの側面
に圧接させたのみであったから第６図、第７図に示すよ
うに同板ガラス１２′の側面始端部１７および終端部１
８は面圧が上昇し過圧状態となり過研磨状態となり品質
を著しく低下させる欠陥があった。Conventionally, the polishing disk was only brought into pressure contact with the side surface of the glass plate using an air cylinder or the like, so as shown in FIGS.
No. 8 had a defect in which the surface pressure increased, resulting in an overpressure state, resulting in an overpolishing state, which significantly deteriorated the quality.

本案は上述のように研磨盤１１が板ガラス１２の側面始
端部に当接すると近接スイッチうのみ上記研磨移動に移
行してその移動はきわめて遅く、空気ノズル１３の信号
によって摺動しているストッパー５の摺動速度は比較的
速いから上記間隙ｔが拡大する。In this case, as described above, when the polishing disk 11 comes into contact with the starting end of the side surface of the glass plate 12, the proximity switch moves to the above-mentioned polishing movement, and the movement is extremely slow, and the stopper 5, which is sliding due to the signal from the air nozzle 13, Since the sliding speed is relatively high, the gap t increases.

そしてその拡大のため電動機７が停止しそれに伴ってス
トッパー５が停止しそのストッパー５に阻止されて上記
研磨盤１１が矢印ａ方向に研磨移動することが無くなる

圧がなく過研磨による板ガラス１２の側面始端部および
終端部の変形を防止し泣等かつ直線状態の板ガラス研磨
側面が得られる効果がある。Then, due to the expansion, the electric motor 7 stops, and the stopper 5 stops accordingly, and the polishing disk 11 is prevented from moving in the direction of the arrow a because it is blocked by the stopper 5. There is no overpressure in the polishing process, and deformation of the side surface starting and ending parts of the glass plate 12 due to overpolishing is prevented, and the polished side surface of the glass plate 12 can be obtained in a straight and straight state.

研磨側面が自動的かつ精度良く得られるものである。Polished side surfaces can be obtained automatically and with high precision.
