Abstract

This scribing device 1 forms a closed curve scribe line 4 on the surface 3 of a glass plate 2 by NC control. The scribing device 1 forms the closed curve scribe line 4 on the glass plate 2 surface 3 by moving a cutter wheel 5 and the glass plate 2 in an X-Y planar coordinate system to produce a contour line while performing an angular control of the cutter wheel 5 around an axial line 37 that is orthogonal to the planar coordinate system so as to orient the blade surface 9 of the cutter wheel 5 to be always in a normal direction 8 to the contour line 10. At the same time, during the movement for forming the scribe line 4, the scribing device 1 switches the cutter wheel 5 in the normal direction 8 between an upright orientation 11, which is orthogonal to the glass plate 2 surface 3, and an orientation 12 that is slanted relative to the glass plate 2 surface 3.

　従来、カッタホイールを用いた自動車窓ガラスのスクライブ折割生産において、そのスクライブ線の形成は、特許文献１に開示されているように、外周全周に渡ってカッタホイールをガラス板面に対して垂直に立てた姿勢で行っている。 Conventionally, in scribe split production of automobile window glass using a cutter wheel, the formation of the scribe line is as follows. It is done in a vertical position.
特開平４－２６５２４４JP-A-4-265244
　しかし、例えば、特許文献１が示すように、カッタホイールをガラス板面に対して垂直に立てた姿勢で自動車窓ガラスの形状に対応してガラス板面をスクライブしたとき、鋭い凸コーナカーブ部又は湾曲カーブ部においては、スクライブ線下の垂直クラックの進行が十分に発生されず、ここに曲げ折割を作用させると、製品側の折割面にソゲ、カケ等が発生したり、スクライブ線に沿った折割が行われない場合もある。 However, as shown in Patent Document 1, for example, when the glass plate surface is scribed corresponding to the shape of the automobile window glass in a posture in which the cutter wheel is set up perpendicular to the glass plate surface, a sharp convex corner curve portion or In the curved curve part, the progress of vertical cracks under the scribe line is not sufficiently generated, and if bending bending is applied here, sores, cracks, etc. occur on the product-side split surface, or the scribe line In some cases, the splitting is not performed.
　また、湾曲カーブ部の曲げ折割においては、スクライブ線外側の折割除去カレットに外方向への離れ力が働かず、折割除去カレットと製品側のガラス板の外周部とが軋り合い、製品側のガラス板の外周部にハマカケ、ソゲが発生したり、折割後に折割り面に研削加工を施しても、カケ、ソゲが残り、正常な最終製品を得られないこともある。 In addition, in the bending splitting of the curved curve portion, the outward detachment force does not work on the split removal cullet outside the scribe line, and the split removal cullet and the outer peripheral portion of the glass plate on the product side meet, There are cases where cracks and sores are generated on the outer peripheral portion of the glass plate on the product side, and even if grinding is applied to the split surface after splitting, the scraps and sores remain and a normal final product cannot be obtained.

On the other hand, the angle is changed, that is, the posture is switched from the standing posture 11 perpendicular to the surface 3 of the glass plate 2 to the inclined posture 12.
　以上のスクライブ装置１は、例えば、スクライブ線４の形成において、直線部又は緩やかなカーブ部５２（Ｂ－Ｂ）では、カッタホイール５をガラス板２の面３に対して垂直した立ち姿勢１１として高速でスクライブ移動させ、鋭い凸コーナカーブ部５０及び湾曲カーブ部５１（Ａ－Ａ）では、カッタホイール５をスクライブ線４の外側域Ｃに向って下り傾斜した姿勢１２に切り換えてスクライブを行うようになっており、これにより、スクライブ装置１では、鋭い凸コーナカーブ部５０及び湾曲カーブ部５１（Ａ－Ａ）において、スクライブ線４の溝及びスクライブ線４の溝直下のクラックを下方に向って下り傾斜して進行発生させることができ、図４に示すように、ガラス板２の外側域Ｃを下方に折割する場合において、製品側の折割面Ｄの下部を上部に対して出っ張り、即ち、下部に向って抜き勾配θを形成できると同時に、ガラス板２の製品側とカレットとなる外側域Ｃとの間の上側を大きく開くようにできるため、スクライブ線４の外側域Ｃの折割除去カレットを外方向に離し易くなり、製品側の折割面Ｄ及びその近傍にカケ、ソゲの発生をなくし得、また、仮令、折割面Ｄの下方の張り出部にソゲ、カケが発生しても、後工程のエッヂ研削仕上げによってソゲ、カケを除去でき、従って、図１に示すような鋭い凸コーナカーブ部５０、湾曲カーブ部５１を有する形状の自動車ガラスにおいても良好に加工仕上げを得ることができる。 In the scribe device 1 described above, for example, in the formation of the scribe line 4, the cutter wheel 5 is set in a standing posture 11 perpendicular to the surface 3 of the glass plate 2 in a straight portion or a gentle curve portion 52 (BB). Scribing is performed at high speed, and the sharp convex corner curve portion 50 and the curved curve portion 51 (AA) are switched to the posture 12 inclined downward toward the outer area C of the scribe line 4 to perform the scribe. Thus, in the scribing apparatus 1, in the sharp convex corner curve portion 50 and the curved curve portion 51 (AA), the groove of the scribe line 4 and the crack immediately below the groove of the scribe line 4 are directed downward. In the case where the outer side area C of the glass plate 2 is folded downward as shown in FIG. The lower part of D protrudes from the upper part, that is, the draft angle θ can be formed toward the lower part, and at the same time, the upper side between the product side of the glass plate 2 and the outer region C serving as the cullet can be opened widely. , It becomes easy to separate the crease removal cullet in the outer area C of the scribe line 4 outward, and it is possible to eliminate the occurrence of cracks and sedges on the product side crease surface D and its vicinity. Even if stagnation or chipping occurs in the lower protruding portion, the sedge or chipping can be removed by edge grinding finishing in the subsequent process, and therefore, it has a sharp convex corner curve portion 50 and a curved curve portion 51 as shown in FIG. Good finishing can be obtained even in the shape of automobile glass.
　上記の例では、カッタホイール５をスクライブ線４の外側域Ｃに向って下り傾斜させたが、本発明は、上記の例とは反対に、カッタホイール５をスクライブ線４の内側域、即ち、製品側に向って下り傾斜させてもよい。 In the above example, the cutter wheel 5 is inclined downward toward the outer region C of the scribe line 4. However, in the present invention, contrary to the above example, the cutter wheel 5 is moved to the inner region of the scribe line 4, that is, the inner region. It may be inclined downward toward the product side.
