- the cutting unit 20 returns to the original height position even when the cutting holding unit 24 is raised, and returns to the above-described cutting unit standby position (see FIG. 2). This is the end of the post-cut conveyance work.
- the cutting unit 20 conveys the glass sheet 90 with the operation of returning to the cutting unit standby position after the cutting operation, the useless movement of the cutting unit 20 is reduced and the cutting operation is performed after the cutting operation.
- the work up to the transfer work can be performed efficiently.
- the lifting height of the plate glass 90 is small, the time for lifting the plate glass 90 can be shortened, and the carrying work can be performed more efficiently.
- the pre-splitting operation is mainly performed by the splitting unit 50.
- the plate glass 90 is conveyed to the first dividing table 71 by the conveying operation after the cutting, and at this time, the dividing unit 50 stands by at the dividing unit standby position downstream of the first dividing table 71. This state is illustrated in FIG. 4 described above.
- the dividing unit 50 moves to a predetermined vertical position in the upstream direction.
- the predetermined vertical position here is a vertical position in which the front dividing bar 52 is positioned vertically above the first dividing groove 79, that is, vertically above the front ear portion 97 of the plate glass 90.
- the dividing unit 50 lowers the front dividing bar 52 and presses the front ear portion 97 from above to apply force. Thereby, the front ear part 97 of the plate glass 90 is parted.
- the front dividing bar 52 is returned to the original height position even if it is raised again. Note that the divided front ear portion 97 falls into the first dividing groove 79 and is dropped and collected in a collection box or chute (not shown) provided therebelow. This completes the pre-splitting operation.
- the conveyance work during the division is mainly performed by the division unit 50.
- the cutting unit 50 moves to a predetermined vertical position in the upstream direction.
- FIG. 5 shows the position of the dividing unit 50 at this time.
- the predetermined position here means that the rear dividing bar 53 is positioned vertically above a portion 98 (hereinafter, this portion is referred to as a “rear ear portion”) outside the rear cut line 94 of the plate glass 90.
- the vertical position The reason why the dividing unit 50 moves to such a vertical position is to smoothly perform the rear left and right dividing operation described later.
- the cutting unit 50 holds the plate glass 90 by lowering the cutting holding unit 56 and sucking the suction pad 65 of the cutting holding unit 56 onto the upper surface of the plate glass 90.
- the dividing unit 50 raises the dividing holding part 56 and lifts the plate glass 90.
- the first lower surface suction pad device 77 stops the suction of the lower surface suction pad 76, and the first dividing base 71 blows out air from the blowing hole 75 on the upper surface.
- the lifting height of the plate glass 90 is about 1 mm as in the case of the post-cut conveyance work.
- the plate glass 90 is divided into the first dividing portion. There is no case where the table 71 is touched and damaged.
- the dividing unit 50 moves in the downstream direction from the first dividing table 71 via the intermediate dividing table 72 to the second dividing table 73 while holding the plate glass 90.
- the 2nd parting stand 73 blows off air from the blowing hole 82 formed in the upper surface.

Abstract
Description
架台10は、切込ユニット20、切込定盤40、分断ユニット50、及び分断台70の各構成要素を支持する台である。ここで、板ガラス90は、図1の紙面左手前側から搬入され、紙面右奥側へと搬出される。つまり、切込ユニット20と分断ユニット50に着目すれば、切込ユニット20が上流側であり分断ユニット50が下流側となる。架台10の右側端部及び左側端部の上面には、それぞれ縦方向に延びる搬送レール11、12が設けられている。また、右側の搬送レール11の下方には、歯形が形成された直線状のラック13が設けられている。このラック13は、架台10の全長にわたって搬送レール11に並行に設けられている。
切込ユニット20は、板ガラス90の所定位置に切込線を形成するユニットであり、切込分断装置100のうち上流側に位置している。図1に示すように、切込ユニット20は、切込移動枠21と、縦断カッター22と、横断カッター23と、切込保持部24と、を有している。
切込定盤40は、板ガラス90に各切込線91~94を形成する際に板ガラス90を載せるための部材である。切込定盤40は切込分断装置100のうち上流側に位置しており、切込分断装置100よりも上流側に位置する他の装置から搬入された板ガラス90はこの切込定盤40上に載せられる。切込定盤40は、平面視において四角形の形状を有しており、板ガラス90よりも縦方向寸法及び横方向寸法がやや大きく、その上面は平らに形成されている。また、本実施形態の切込定盤40は、板ガラス90に対向する面(上面)に複数の空気孔41が形成されており、切込定盤40はこれらの空気孔41によって板ガラス90を吸引して上面に板ガラス90を固定できるように構成されている。さらに、切込定盤40の上面と板ガラス90が離れるように、空気孔41から空気を吹き出すこともできる。
分断ユニット50は、切込ユニット20によって形成される切込線に沿って板ガラス90を分断するユニットであり、切込分断装置100において切込みユニット20の下流側に位置している。図1に示すように、分断ユニット50は、分断移動枠51と、複数の分断バー52~55(図2以降も参照)と、分断保持部56と、を有している。
分断台70は、板ガラス90を分断する際に板ガラス90を載せるための台である。本実施形態の分断台70は、第1分断台71と、中間分断台72と、第2分断台73とから主に構成されている。
切込作業は、主に切込ユニット20によって行われる。まず、切込ユニット20は切込定盤40よりも下流側の切込ユニット待機位置で待機する。このときの切込ユニット20の位置を図示したのが図2である。切込ユニット20が待機している間に、切込分断装置100よりも上流側に位置する他の装置によって切込定盤40上に板ガラス90が搬入される。切込定盤40上に搬入された板ガラス90は、切込定盤40の空気孔41によって吸着され、切込定盤40の上面に固定される。
切込後搬送作業は、主に切込ユニット20によって行われる。切込作業後、切込ユニット20は、切込保持部24を下降して吸着パッド33を板ガラス90の上面に吸着させ、板ガラス90を保持する。なお、この動作は、上述の後切込線94を形成する動作と同時に行えば、全体の作業として作業時間を短縮することができる。
前分断作業は、主に分断ユニット50によって行われる。上述のように、切込後搬送作業により板ガラス90が第1分断台71に搬送されるが、その際、分断ユニット50は第1分断台71よりも下流側の分断ユニット待機位置で待機する。この状態を図示しているのが、上述した図4である。
分断中搬送作業は、主に分断ユニット50によって行われる。前分断作業後、分断ユニット50は上流方向に向かって所定の縦方向位置まで移動する。このときの分断ユニット50の位置を図示したのが図5である。ここでいう所定位置とは、板ガラス90の後切込線94よりも外側の部分98(以下、この部分を「後耳部」と呼ぶ。)の鉛直上方に後分断バー53が位置するような縦方向位置である。分断ユニット50がこのような縦方向位置に移動するのは、後述する後左右分断作業を円滑に行うためである。そして、分断ユニット50は、分断保持部56を下降させて分断保持部56の吸着パッド65を板ガラス90の上面に吸着させて板ガラス90を保持する。
後左右分断作業は、主に分断ユニット50によって行われる。分断中搬送作業後、分断ユニット50は、後分断バー53を下降させて板ガラス90の後耳部98に上方から力を加える。なお、上述したように、分断中搬送作業において、事前に後分断バー53を後耳部98の鉛直上方に位置させているため、特別な位置合わせをすることなく単に後分断バー53を下降させれば後耳部98に力を加えることができる。これにより、板ガラス90の後耳部98は分断される。
