Description

ガラス板の研削加工装置Glass plate grinding equipment
 本発明は、自動車の窓ガラス板のように形状、寸法が多種あるガラス板の外周縁を研削加工するガラス板の研削加工装置に関する。 The present invention relates to a glass plate grinding apparatus for grinding an outer peripheral edge of a glass plate having various shapes and dimensions such as a window glass plate of an automobile.
 従来のガラス板の研削加工装置は、研削ホイールを備えた研削ヘッドと、ガラス板を水平吸着して直動又はθ回転を行う研削ワークテーブルと、ガラス板を吸着して研削ワークテーブル上へ直動移動し、この研削ワークテーブルにガラス板の搬入載置を行うガラス板の搬送装置とを備え、これら研削ヘッド、研削ワークテーブル及び搬送装置は、数値制御されて移動又はθ回転を行って、ガラス板の外周縁の研削加工を行うようになっており、研削ワークテーブルは、数値制御されて直動又はθ回転を行うテーブル本体とこのテーブル本体の上面に吸着してこのテーブル本体に保持される複数個の吸盤とを具備しており、複数個の吸盤の上面において加工ガラス板を吸着保持するようになっている。この従来のガラス板の研削装置は、研削すべきガラス板の形状及び寸法のうちの少なくとも一方の変更に際しては、先ず、ガラス板の搬送装置により、次の研削すべきガラス板を吸着して、研削ワークテーブル上までガラス板を直動移動させ、研削ワークテーブルの上方でガラス板を吸着保持状態で停止させ、側方からガラス板とテーブル本体の上面との間に、複数の吸盤を次々に差し入れ、目測により複数の支持必要位置の各々に吸盤を配置し、吸盤をテーブル本体の上面に吸着させることにより、複数吸盤の研削ワークテーブルへの配置作業を終えるようになっている。 A conventional glass plate grinding apparatus includes a grinding head equipped with a grinding wheel, a grinding work table that moves the glass plate horizontally and linearly moves or rotates θ, and sucks the glass plate directly onto the grinding work table. And a glass plate conveying device for carrying and placing the glass plate on the grinding work table.The grinding head, the grinding work table and the conveying device are numerically controlled to move or rotate θ, The outer periphery of the glass plate is ground, and the grinding work table is held numerically controlled by the table body that performs linear motion or θ rotation and the upper surface of the table body. A plurality of suction cups are provided, and the processed glass plate is adsorbed and held on the upper surfaces of the plurality of suction cups. In this conventional glass plate grinding apparatus, when changing at least one of the shape and dimensions of the glass plate to be ground, first, the glass plate to be ground is adsorbed by the glass plate transport device, Move the glass plate linearly to the grinding work table, stop the glass plate in the suction holding state above the grinding work table, and place multiple suction cups one after the other between the glass plate and the upper surface of the table body. By inserting and sucking the suction cups at each of the plurality of necessary support positions, and by sucking the suction cups onto the upper surface of the table body, the arrangement work of the plurality of suction cups on the grinding work table is completed.
 そして、ガラス板は、上記のように、研削ワークテーブル上面に吸着保持されるが、形状、寸法が多種に及ぶガラス板の吸着保持は、1個の吸盤では困難であり、このため従来のガラス板の研削加工装置は、複数(6~13個)の吸盤を備え、ガラス板の形状、寸法に対応し、ガラス板を支持するに適正な複数箇所(6~13箇所)の位置に分けて配置して、ガラス板の吸着保持を行っている。 As described above, the glass plate is sucked and held on the upper surface of the grinding work table. However, it is difficult to suck and hold a glass plate having various shapes and dimensions with a single sucker. The plate grinding device is equipped with multiple (6 to 13) suction cups, which correspond to the shape and dimensions of the glass plate and are divided into multiple locations (6 to 13) that are appropriate for supporting the glass plate. Arranged to hold the glass plate by suction.

 しかし、従来のガラス板研削加工装置における研削ワークテーブルへの複数の吸盤の配置作業は、目測による位置への配置であるため、ガラス板形状に適正に合わせた配置作業に時間を要する上に、ガラス板の外周縁の限界を越えた誤り配置となることがあると、実際の研削加工において、研削ホイール又は研削ホイールカバーと吸盤とが衝突し、ガラス板の支持が狂い、研削加工が不良となり、また、ガラス板の破損を起こす虞がある。 However, since the arrangement work of the plurality of suction cups on the grinding work table in the conventional glass plate grinding apparatus is an arrangement to the position by visual inspection, it takes time to arrange the glass sheet shape appropriately. If the misplacement exceeds the limit of the outer peripheral edge of the glass plate, the grinding wheel or grinding wheel cover and the suction cup may collide with each other in the actual grinding process, and the support of the glass plate will be out of order, resulting in poor grinding. Moreover, there is a risk of causing breakage of the glass plate.
 そこで、本発明は、従来のガラス板の研削加工装置の上記のような欠陥に鑑みてなされたもので、その目的とするところは、研削加工すべきガラス板の形状及び寸法の変更に際して、複数の吸盤の配置変えの作業を迅速に行い得、且つ複数個の吸盤を、ガラス板の形状、寸法に対応して適正な配置にし得るガラス板の研削装置を提供することにある。 Therefore, the present invention has been made in view of the above-mentioned defects of the conventional glass plate grinding apparatus, and the object thereof is to change the shape and dimensions of the glass plate to be ground.

The drawing device draws at least one of the arrangement positions and the arrangement ranges of the plurality of suction cups corresponding to the pattern change on the upper surface of the table body.
 また、本発明のガラス板の研削加工装置は、ガラス板を研削する研削ホイールを備えていると共に、Y軸移動を行う研削ヘッドと、テーブル本体及びこのテーブル本体の上面に吸着してこのテーブル本体に保持されると共に、上面でガラス板を吸着保持する複数の吸盤を備えてθ回転を行う回転テーブルと、この回転テーブルの複数の吸盤の上面にガラス板の搬入載置を行う搬送装置とを備えているガラス板の研削加工装置であって、研削ヘッド及び回転テーブルを相対的にY-θ平面極座標系移動させて複数の吸盤の上面に吸着保持されたガラス板の外周の研削加工を行うようになっており、搬送装置は、回転テーブルに対してX軸直動すると共に、描画装置が設けられている移動体と、この移動体に装着されていると共に、ガラス板を吸着してガラス板の昇降を行う吸着パット昇降装置とを備えてなるガラス板の研削加工装置であって、研削加工すべきガラス板の形状及び寸法のうちの少なくとも一方に関するパターン変更に伴う複数の吸盤の再配置に際し、テーブル本体の上面に吸着配置された吸盤を当該テーブル本体の上面から取り除いた状態での回転テーブルのθ回転と移動体のX軸移動とにより、テーブル本体及び描画装置をX-θ平面極座標系移動させ、描画装置によりテーブル本体の上面にパターン変更に対応した複数の吸盤の配置位置及び配置範囲のうちの少なくとも一方を描画するようになっている。 The glass plate grinding apparatus of the present invention is equipped with a grinding wheel for grinding a glass plate, and is attached to a grinding head for moving the Y axis, a table body, and the upper surface of the table body.

A glass plate grinding device comprising a suction pad lifting device that lifts and lowers the glass plate by wearing a plurality of patterns associated with a pattern change relating to at least one of the shape and dimensions of the glass plate to be ground When the suction cups are rearranged, the rotation of the rotary table with the suction cups attached to the upper surface of the table main body removed from the upper surface of the table main body and the X-axis movement of the moving body causes the table main body and the drawing apparatus to move to X. By moving the -θ plane polar coordinate system, the drawing device draws at least one of the arrangement positions and the arrangement ranges of the plurality of suction cups corresponding to the pattern change on the upper surface of the table body.
 本発明において、描画装置は、マーカ筆記具、ディスペンサー(液体の定量吐出装置)又は液滴吐出装置等であるが、描画用の液剤を定量吐出するディスペンサーが描画装置としては好適である。さらに、テーブル本体の上面から高く離れた位置から描画液を飛ばし、テーブル本体の上面に吹き付けし、描画を形成する非接触方式のジェットディスペンサーも好適であり、また、液剤の色調は、テーブル本体の上面の描画が視認できる程度でもよく、更には、ガラス板の形状及び寸法のうちの少なくとも一方の変更に際して直前の描画表示を消去するようにする場合には、消去性に優れた液剤が好ましいが、斯かる消去を行わないようにする場合には、描画装置は、以前の描画表示と新たな描画表示とを識別できるような、例えば色の異なる液剤を吐出できるようになっているとよい。 In the present invention, the drawing device is a marker writing instrument, a dispenser (liquid quantitative discharge device), a droplet discharge device or the like, but a dispenser for quantitatively discharging a drawing liquid is suitable as the drawing device.

In the case where such erasure is not performed, the drawing apparatus may be configured to be able to discharge liquid agents having different colors, for example, so that the previous drawing display and the new drawing display can be distinguished.
 本発明によれば、研削ワークテーブルに対してガラス板を搬送する搬送装置の移動体に描画装置が併設され、加工すべきガラス板の形状及び寸法の変更に伴う吸盤の配置変更に際し、テーブル本体上から吸盤を取り除いた状態において、移動体のX軸移動と研削ワークテーブルのY軸移動とにより、描画装置と研削ワークテーブルとのXY平面座標系移動を行なわせ、描画装置により、研削ワークテーブル上にガラス板の形状及び寸法に応じた吸盤の配置位置及び吸盤配置の範囲を描画し、また、回転テーブルに対してガラス板を搬送する搬送装置の移動体に描画装置が併設され、加工すべきガラス板の変更に伴う吸盤の再配置において、回転テーブルのテーブル本体上から吸盤を取り除いた状態において、移動体のX軸移動と回転テーブルのテーブル本体のθ回転とにより描画装置と回転テーブルのテーブル本体との平面極座標系移動を行なわせ、描画装置により、回転テーブルのテーブル本体の上面に、ガラス板の形状及び寸法に応じた吸盤の配置及び吸盤配置範囲を描画することにより、テーブル本体の上面に描画された配置支持位置及び配置範囲に従って吸盤を配置でき、その結果、加工すべきガラス板の変更に伴う吸盤の再配置作業が安全にして迅速に行い得、ガラス板の研削加工を行う周縁縁を確りと水平支持するに効果的にして安全な位置に吸盤を配置し得、ガラス板の周縁縁に近過ぎることなく、周縁縁の近くに吸盤を配置し得る。 According to the present invention, a drawing device is provided together with a moving body of a conveying device that conveys a glass plate with respect to a grinding work table, and the table main body is changed upon changing the arrangement of the suction cups accompanying the change in the shape and dimensions of the glass plate to be processed. In a state where the suction cup is removed from the top, the X-axis movement of the moving body and the Y-axis movement of the grinding work table cause the drawing apparatus and the grinding work table to move in the XY plane coordinate system. The drawing position of the suction cup and the range of the suction cup placement according to the shape and dimensions of the glass plate are drawn on top, and the drawing device is attached to the moving body of the transfer device that transfers the glass plate to the rotary table.
