Description

明細書 ガラス板の加工機械 技術分野  Description Glass plate processing machine Technical field
本発明はガラス板の加工機械に関する 。 背景技術  The present invention relates to a glass sheet processing machine. Background art
従来のガラス板の加工機械においては、 加工工具を一の 平面内の互いに直交する二方向に夫々直線移動させて 、 加 ェされるべき ガラス板の加工点に加工工具の加工部を位置 決めするか、 又は加工工具を一の平面内の一の直線方向に 移動させる一方、 加工されるべきガラス板を 、 一の平面内 であって加工工具の移動方向に直交する他の直線方向に移 動させて 、 加工されるべき ガラス板の加工点に対して加工 工具の加工部を相対的に位置決めし、 これによ り例えばガ ラス板の全周縁にエ ッ ジング、 面取 り又は研磨等を施すよ う に して いる 。  In a conventional glass sheet processing machine, a processing tool is linearly moved in two directions orthogonal to each other in one plane, and a processing portion of the processing tool is positioned at a processing point of a glass sheet to be added. Or while moving the working tool in one linear direction in one plane, while moving the glass sheet to be worked in another linear direction in one plane and orthogonal to the moving direction of the working tool. Then, the processing portion of the processing tool is positioned relatively to the processing point of the glass plate to be processed, whereby, for example, the entire periphery of the glass plate is subjected to etching, chamfering or polishing. I am trying to give it.
と こ ろで上述のよ う な従来のガラス板の加工機械では、 加工工具を、 ガラス板の一つの周縁位置から この周縁位置 に対向する反対側の周縁位置まで移動させる こ とができ る よ う に形成されて いないと 、 ガラス板の全周囲についての 例えば面取 り を行う こ とができず、 そのため加工工具が矜 動する領域上には、 例えば固定配置されたガラス板固定装 置等を設ける こ とが困難であって 、 従来のこの種ガラス板 の加工機械では、 ガラス板が載置されるテーブル側に吸盤 装置を設け、 この吸盤装置でも ってガラス板を吸引 してガ ラス板をテーブル側から固定し、 このよ う にして片面側の みで固定されたガラス板に対して例えば面取 りなどが施さ れて いる 。 しかしながら 、 片面固定である と しっかり と確 実にガラス板を固定する こ とが困難であって 、 例えば面取 りのためにガラス板の周縁を切削すべく 加工工具をガラス 板の周縁へ押圧しよ う とする と ガラス板が正規の位置から ずれて しま う虞がある 。 また従来のガラス板の加工機械で は、 複数個の加工工具を設けて各加工工具に加工領域を分 担させて加工を施し、 これによ り加工時間を短縮する こ と も困難であって 、 短い時間で大量の加工されたガラス板を 得る こ とができない。 Meanwhile, in the conventional glass sheet processing machine as described above, the processing tool can be moved from one peripheral position of the glass plate to a peripheral position opposite to the peripheral position. If it is not formed, the entire periphery of the glass plate cannot be chamfered, for example. For example, it is difficult to provide a glass plate fixing device or the like fixedly arranged on the moving area. In a conventional glass sheet processing machine, a suction cup is provided on a table side on which the glass plate is placed. An apparatus is provided, and the glass plate is suctioned by this suction device to fix the glass plate from the table side. In this way, for example, the glass plate fixed on only one side can be chamfered. It has been subjected . However, it is difficult to fix the glass plate firmly with one-sided fixing. For example, press a processing tool against the periphery of the glass plate to cut the periphery of the glass plate for chamfering. If this is attempted, the glass plate may be displaced from the proper position. Also, with a conventional glass sheet processing machine, it is difficult to provide a plurality of processing tools and perform processing by sharing the processing area for each processing tool, thereby reducing the processing time. However, a large number of processed glass sheets cannot be obtained in a short time.
加えて加工工具の一つである面取 り用の研削ホイ ールを 旋回させて加工点でのガラス板の加工されるべき輪郭に対 して法線方向に研削ホイ ールの回転中心を配置する旋回装 置を更に具備して いるガラス板の加工機械では、 ガラス板 の全周囲の面取りで旋回装置によ り研削ホイ ールがー旋回 される場合、 研削ホイ ールを回転させる例えば電動モータ への配線又は研磨剤溶液を供給する可撓性パイ プが不必要 に捩じられた り 、 電動モータ又はこれを支持する ブラケ ッ 卜等に卷き付いた り して しま い、 次の作業に移る場合にこ の捩じれ卷き付き を除いて元に戻さなければならない等の 不都合がある 。 In addition, the grinding wheel for chamfering, which is one of the processing tools, is turned to set the center of rotation of the grinding wheel in the normal direction to the contour of the glass sheet to be processed at the processing point. In a glass sheet processing machine further provided with a turning device to be disposed, when the grinding wheel is turned by a turning device in a chamfer around the entire periphery of the glass sheet, for example, the grinding wheel is rotated. The wiring to the electric motor or the flexible pipe supplying the abrasive solution is unnecessarily twisted, or the electric motor or the bracket supporting it is unnecessarily twisted. There are inconveniences, such as being wrapped around a bird, etc., and when moving on to the next work, it is necessary to return to the original position, excluding the twisted wrap.

このよ う に構成されたガラス板の加工機械 1 のモータ ら 3 2 、 6 5及び 7 0は、 図示しない数値制御装置の予めァ ログラムされた数値制御命令で作動される よ う になってい る 。 The motor of the glass sheet processing machine 1 constructed in this way Numerals 32, 65 and 70 are operated by a pre-programmed numerical control command of a numerical controller (not shown).
ガラス板の加工機械 1 は次のよ う にガラス扳 2 に対して 面取 り作業を行う 。 まず、 ノブ 8 4 、 8 6及び 8 8を回転 させて研削ホイール 4 を P 、 Q及び Z方向に移動させて研 削ホイ ール 4の周縁をガラス板 2の周緣 1 3 に接触させる 尚、 研削ホイ ール 4 と ガラス板 2 との接触位置、 即ち加工 部 Cでも ある加工点 Aが軸 1 1 上に位置し、 加工点 Aでの ガラス板 2の研削すべき周縁 1 3の接線に直交する方向、 換言すれば加工点 Aでの法線方向 （ E方向） に研削ホイ 一 ル 4 の回転中心 1 4が位置する よ う に、 軸 1 1 を中心と し てブラケ ッ ト 8 5 を回転させて 、 初期設定を行う 。 このよ う な初期設定状態では、 P方向と E方向とが同方向と なる 結果、 ノブ 8 4 を回転する こ とは、 ガラス板 2 に対する研 削切込量を調節する こ と となる 。  The glass plate processing machine 1 chamfers the glass 2 as follows. First, the knobs 84, 86, and 88 are rotated to move the grinding wheel 4 in the P, Q, and Z directions so that the periphery of the grinding wheel 4 contacts the periphery 13 of the glass plate 2. The contact point between the grinding wheel 4 and the glass plate 2, that is, the processing point A, which is also the processing part C, is located on the axis 11 and the tangent to the peripheral edge 13 of the glass plate 2 to be ground Bracket 85 around axis 11 so that the rotation center 14 of grinding wheel 4 is located in the direction perpendicular to the machining point A, that is, in the normal direction (E direction) at machining point A. Rotate to make the initial settings. In such an initial setting state, the P direction and the E direction are in the same direction. As a result, when the knob 84 is rotated, the amount of grinding cut into the glass plate 2 is adjusted.
次に数値制御装置を作動させる こ と によ り 、 これに制御 されてモータ 6 、 3 2 、 6 5及び 7 0は作動され、 移動台 3 5の X方向の移動と ガラス板 2の R方向の回転とで研削 ホイ ール 4の加工部 Cは、 ガラス板 2の研削すべき周緣 1 3 に沿って位置決めされる と共に、 研削ホイ ール 4 自体の 回転によ り加工点 Aでガラス板 2 に面取 りが施される 。 面 取 り 中、 研削ホイ ール 4の回転中心 1 4が加工点 Aでの力' ラス板 2 の面取りすべき周縁 1 3 に対する法線方向、 即ち E方向に位置する よ う に、 モータ 7 0 の作動でブラケ ッ ト 8 5が軸 1 1 を中心と して F方向に旋回される 。 Next, by operating the numerical controller, the motors 6, 32, 65, and 70 are operated under the control of the numerical controller, and the moving table 35 moves in the X direction and the glass plate 2 moves in the R direction. The processing part C of the grinding wheel 4 is positioned along the circumference 13 of the glass plate 2 to be ground, and the rotation of the grinding wheel 4 itself causes the glass plate 4 to rotate at the processing point A. 2 is chamfered. During chamfering, the center of rotation 14 of grinding wheel 4 is the force at machining point A '. By operating the motor 70, the bracket 85 is rotated in the F direction about the shaft 11 so that the lath plate 2 is positioned in the normal direction to the peripheral edge 13 to be chamfered, that is, in the E direction. .
と ころで本例のガラス板の加工機械 1 では、 ガラス板 2 を R方向に回転させて面取 り されるべき加工点 Aを研削ホ ィ 一ル 4 に対して位置決め して いるため、 研削ホイ ール 4 延いてはモータ 6の軸 1 1 を中心とする F方向の旋回は 3 6 0度を越えてなされる こ とはなく 、 多 く の場合 1 8 0度 以内 とな り 、 従ってモータ 6への配線、 研磨剤供給パイ プ 等がブラケッ ト 8 5等に絡み付いた り卷き付いた りするこ とがなく 、 その結果一つのガラス板に対する面取 り完了後 次のガラス板に対して面取 り を行う場合、 ブラケ ッ ト 8 5 等に絡み付き卷き付いたモータ €>への配線、 研磨剤供給パ ィ ァ等を元に戻すべく 、 ブラケ ッ ト 8 5 を逆転するなどの 作業を必要と しないで、 直ぐに作業にと りかかる こ とがで き る 。  However, in the glass sheet processing machine 1 of this example, since the glass sheet 2 is rotated in the R direction to position the processing point A to be chamfered with respect to the grinding wheel 4, grinding is performed. The rotation in the F direction about the axis 11 of the wheel 4 and thus the motor 6 will not be made more than 360 degrees, and in many cases will be within 180 degrees. The wiring to the motor 6, the abrasive supply pipe, etc., do not become entangled or wrapped around the bracket 85, and as a result, after the chamfering of one glass sheet is completed, the next glass sheet If chamfering is to be performed on the bracket 85, the bracket 85 should be reversed to restore the wiring to the motor wrapped around the bracket 85, etc., the abrasive supply pier, etc. You can get to work immediately without the need for additional work.
