Description

【０００１】
【発明の属する技術分野】
この発明は、液晶パネルの分断システムに関する。
【０００２】
【従来の技術】
液晶パネルは、二枚の板ガラスを貼り合わせて形成してある。
【０００３】
このような液晶パネルを製品サイズに分断（分割）する従来技術としては、図１５に示すように、まず前後方向に走行する第１ステージ１に入手や入れ込み機などによって液晶パネルＡを供給したのち、第１切断機１１のカッタにより上記第１ステージ１上の液晶パネルＡのＡ面（上面に位置する片面）に切断線Ｂをスライブ（入れる）する。
【０００４】
上記の切断線Ｂは、大割と小割とに分断するために一方向のスライブ終了後第１ステージ１を９０°旋回させて交差する他方向のスライブをする。
【０００５】
次に、第１ステージ１上のスライブずみ液晶パネルＡを適宜の移載手段により第１反転装置２に供給し、供給後に第１反転装置２により液晶パネルＡを１８０°反転（スライブした切断線Ｂが下面に位置するように）する。
【０００６】
そして、反転ずみ液晶パネルＡを前後方向に走行する第２ステージ３上に適宜の移載手段により供給したのち、前方に第２ステージ３を間歇走行させ、かつ第２ステージ３の停止時に昇降するバー材やロールの折割部材４を有する第１折割装置５によりスライブの部分を順次折割する。
【０００７】
なお、一方向のスライブの折割後に第２ステージ３を９０°旋回させ、上述のように他方向のスライブを折割する。
【０００８】
その後に、第２ステージ３上の折割ずみ液晶パネルＡを適宜の移載手段６により前後方向に走行する第３ステージ７上に供給したのち、第２切断機８のカッタにより第３ステージ７上の液晶パネルＡのＢ面（上面に位置するもう片面）に切断線Ｃをスライブする。
【０００９】
上記の切断線Ｃは、Ａ面の切断線Ｂに一致し、かつ切断線Ｂと同様に大割と小割とに分断するために一方向のスライブ終了後に第３ステージ７を９０°旋回させて交差する他方向のスライブをする。
【００１０】
次に、第３ステージ７上のスライブずみ液晶パネルＡを適宜の移載手段により第２反転装置９に供給して、供給後に第２反転装置９により液晶パネルＡを１８０°反転（スライブした切断線Ｃが下面に位置するように）する。
【００１１】
そして、反転ずみ液晶パネルＡを前後方向に走行する第４ステージ１０に適宜の移送手段により供給したのち、前方に第４ステージ１０を間歇走行させ、かつ第４ステージ１０の停止時に第１折割装置５と同様の第２折割装置１１にスライブの部分を順次折割する。
【００１２】
なお、一方向のスライブの折割後に第４ステージ１０を９０°旋回させ、上述のように他方向のスライブを折割する。
【００１３】
しかして、大割の液晶パネルを折割して小割の液晶パネルを得る。
【００１４】
【発明が解決しようとする課題】
上記のような液晶パネルを製品サイズに分断するシステムによると、Ａ面にスライブした液晶パネルを前方の第１折割装置に、またＢ面にスライブした液晶パネルを前方の第２折割装置にそれぞれ移送する際、反転装置によって液晶パネルを反転するので、総機長が著しく長くなって大幅な設置場所を必要とする問題があった。
【００１５】
また、製品パネルの枚数を一度に多く得るために大判（大形）な液晶パネルを分断しようとすると、液晶パネルの重量が著しく増加するので、増加した重量に見合う大型な反転装置が必要になるので、設備費の大幅なアップになると共に、大型化により総機長も増加する問題が起生した。
【００１６】
そこで、この発明は、液晶パネルの反転をなくして上述の各問題を解決することにある。
【００１７】
【課題を解決するための手段】
上記の課題を解決するために、この発明は、水平な姿勢で供給された液晶パネルを上面に適宜の保持手段により保持して前後方向に走行すると共に、上記保持液晶パネルを旋回させる旋回機能付の第１ステージと、この第１ステージの走行路の途中に上記保持液晶パネルの上側Ａ面に切断線をスライブするように設けた第１切断装置と、上記第１ステージの走行路上側の延長線上で前後方向に走行すると共に、下面に前進停止した上記第１ステージの液晶パネルを荷受けして適宜の保持手段により保持し、かつ上記保持液晶パネルを旋回させる旋回機能付の第２ステージと、この第２ステージの走行路途中の下側に上記液晶パネルの下側Ｂ面に作用させてＡ面の切断線を折割するように設けた第１折割装置及び上記Ｂ面に切断線をスライブするように設けた第２切断装置と、上記前進停止した第２ステージの液晶パネルを上面に荷受けして保持すると共に、前後方向に走行し、かつ上記保持液晶パネルを旋回させる旋回機能付の第３ステージと、この第３ステージの走行路途中の上側に上記液晶パネルの上側Ａ面に作用させてＢ面の切断線を折割するように設けた第２折割装置とからなる構成を採用する。
【００１８】
また、立てかけた姿勢で供給された液晶パネルを起立面に適宜の保持手段により保持して前後方向に走行すると共に、上記保持パネルを旋回させる旋回機能付の第１ステージと、この第１ステージの走行路の途中に上記保持パネルの表側Ａ面に切断線をスライブするように設けた第１切断装置と、上記第１ステージの走行路延長線上で前後方向に走行すると共に、起立面に前進停止した上記第１ステージの液晶パネルを荷受けして適宜の保持手段により保持し、かつ上記保持液晶パネルを旋回させる旋回機能付の第２ステージと、この第２ステージの走行路途中に上記液晶パネルの表側Ｂ面に作用させてＡ面の切断線を折割するように設けた第１折割装置及び上記Ｂ面に切断線をスライブするように設けた第２切断装置と、上記前進停止時の第２ステージからの液晶パネルを起立状態に荷受けして保持すると共に、前後方向に走行し、かつ保持液晶パネルを旋回させる旋回機能付の第３ステージと、この第３ステージの走行路の途中に、上記液晶パネルの表側Ａ面に作用させてＢ面の切断線を折割するように設けた第２折割装置とからなる構成を採用することもある。
【００１９】
【発明の実施の形態】
この発明の実施の形態を添付図面に基づいて説明する。
【００２０】
この発明の第１の実施形態では、図１から図８に示す２１は、水平な姿勢で供給（人手や入れ込み機などにより）された液晶パネルＡを上面に保持して前後方向に走行すると共に、上記保持液晶パネルＡを旋回させる旋回機能２２付の第１ステージである。
【００２１】
２３は、第１ステージ２１の走行路上側の前方に向く延長線上で前後方向に走行すると共に、下面に第１ステージ２１の液晶パネルＡを荷受けして保持し、かつ保持液晶パネルＡを旋回させる旋回機能２２付の第２ステージである。
【００２２】
３１は第２ステージ２３の走行路下側の前方に向く延長線上で前後方向に走行すると共に、上面に第２ステージ２３の液晶パネルＡを荷受けして保持し、かつ保持液晶パネルＡを旋回させる旋回機能２２付の第３ステージである。
【００２３】
上記第１ステージ２１、第２ステージ２３及び第３ステージ３１の前後方向の走行は、図示の場合、第１ステージ２１の下側に二条の下側ガイドレール２４を、第２ステージ２３の上側に二条の上側レール２６、第３ステージ３１の下側に二条の下側レール２４をそれぞれ敷設して、下側レール２４に第１ステージ２１の下面両側に設けてあるスライダ２５をスライド自在に、上側レール２６に第２ステージ２３の上面両側に設けてあるスライダ２５をスライド自在に、第３ステージ３１の下面両側に設けてあるスライダ２５をスライド自在に（上側レール２６に対し第２ステージ２３のスライダ２５は、滑走自在な掛吊状態に）係合し、上側レール２６及び前後の下側レール２４に沿わせて軸承すると共に、それぞれモーター２７により可逆駆動する雄ネジ２８を第１ステージ２１、第２ステージ２３及び第３ステージ３１にそれぞれ設けてある雌ネジ２９にねじ込んで、モーター２７の運転により雄ネジ２９を可逆駆動して第１ステージ２１、第２ステージ２３及び第３ステージ３１を前後方向に走行させている。
【００２４】
また、第１ステージ２１、第２ステージ２３及び第３ステージ３１による液晶パネルＡの保持は、図示の場合ステージを構成する吸引ボックス３０の第１ステージ２１及び第３ステージ３１にあっては、頂壁に、第２ステージ２３にあっては、底壁にそれぞれ無数の小孔を設けて吸引により行ない、保持パネルＡの旋回機能２２は、図示の場合、吸引ボックス３０の旋回軸３２をモーターなどの駆動手段３３により駆動して吸引ボックス３０を旋回させる。
【００２５】
さらに、第１ステージ２１から第２ステージ２３に、第２ステージ２３から第３ステージ３１に液晶パネルＡを荷受けする手段としては、人的或いは機械的に行なうもので、図示の場合は、図５に示すように第１ステージ２１及び第３ステージ３１を吸引ボックス３０の旋回機能２２付座材３４とスライダ２５を有する走行台車３５とを別々に形成し、走行台車３５上に据え付けたシリンダ３６のピストンロッドを座材３４に連結すると共に、走行台車３５の上面と座材３４とにそれぞれ末端を固定した軸材と筒体との先端部分をスライド自在に嵌装したガイド部材３７によりガイドし、シリンダ３６の伸長、収縮作用により吸引ボックス３０を昇降させて、第１ステージ２１、第３ステージ３１を上昇し、第１ステージ２１の液晶パネルＡを第２ステージ２３の吸引ボックス３０に吸引保持させ、また第２ステージ２３の液晶パネルＡを第３ステージ３１の吸引ボックス３０に吸引保持させるようにしてある。
【００２６】
また、第１ステージ２１の走行路の途中に第１ステージ２１に保持させてある液晶パネルＡの上側Ａ面に、第２ステージ２３の走行路の途中に第２ステージ２３に保持させてある液晶パネルＡの下側Ｂ面にそれぞれ切断線Ｂ、Ｃを入れる第１切断装置Ｅ、第２切断装置Ｆが設けてある。
【００２７】
上記の第１切断装置Ｅ及び第２切断装置Ｆとしては、周知のように（図２、３、４、６に示す）、第１ステージ２１及び第２ステージ２３の走行路に門形のフレーム４０を立設して、このフレーム４０の水平部材４１に設けてある水平なレール４２にベース４３のスライダ４４をスライド自在に係合すると共に、ベース４３の全長に設けてあるレール４５に各自横方向にスライド自在な切断線Ｂ、Ｃの数に見合う支持部材４６を並設し、この各支持部材４６にシリンダ４７の作用によって昇降するカッタ４８を設けてある。
【００２８】
なお、各支持部材４６には、自走手段４９（ベース４３の全長に設けたラックに各支持部材４６に据え付けたモーターにより駆動するピニオンを噛み合わせて構成したもの）が設けてあって、カッタ４８の並列間隔を調整することができ、ベース４３は、自走手段５０（ベース４３の雌ネジにねじ込んだ雄ネジをモーターにより駆動して）により横移動できて、並列カッタ４８の全体を横移動調整できる。
【００２９】
さらに、第２ステージ２３の走行路の下側で、第２切断装置Ｆの手前には、液晶パネルＡのＢ面に作用させて切断線Ｂを折割（切断線Ｂを浸透させる）する第１折割装置Ｇが、第３ステージ３１の走行路の途中には、液晶パネルＡのＡ面に作用させて切断線Ｃを折割（切断線Ｃを浸透させる）する第２折割装置Ｈが設けてある。
【００３０】
上記の第１折割装置Ｇ及び第２折割装置Ｈとして、図６、７、８に示すように、フレーム５１に筒体とこの筒体に貫通させた軸材とからなるガイド部材５２に案内されてシリンダ５３により上下方向に昇降するようガイドする支持部材５４と、この支持部材５３に横架した折割部材５５（図示の折割部材５５は、ロールを用いたが、切断線Ｂや切断線Ｃに加圧力や弱い衝撃力を作用させるバー材などであってもよい）とで構成されている。
【００３１】
図中５６は液晶パネルＡの辺縁検知カメラで、カメラ５６により検知された辺縁が正常に位置（線上）から変位していると、駆動手段３３により第１ステージ２１、第２ステージ２３を微量旋回させて位置（辺縁の）修正を行なう。
【００３２】
次に、上記構成による液晶パネルＡの分断方法を図９の工程図により説明する。
【００３３】
まず、後退停止している第１ステージ２１の吸引ボックス３０上に、人手や入れ込み機により液晶パネルＡを供給し、吸引ボックス３０内の吸引よって吸引ボックス３０上に液晶パネルＡを保持する。
【００３４】
液晶パネルＡは、周知のように、二板の板ガラスを貼り合わせて形成されている。
【００３５】
次に、第１ステージ２１を前方に走行させる。
このとき、第１切断装置Ｅのカッタ４８により液晶パネルＡの上側Ａ面に並列する切断線Ｂをスライブ（入れる）する。
【００３６】
上記のスライブ後にカッタ４８を上昇させ、次いで第１ステージ２１を後退させると共に、後退途中或いは後退後に駆動手段３３の運転により第１ステージ２１を９０°旋回させる。
【００３７】
然るのち、第１ステージ２１を再度前方に走行させると共に、走行途中に第１切断装置Ｅのカッタ４８により液晶パネルＡのＡ面に前の切断線Ｂに交差する切断線Ｂをスライブする。
【００３８】
交差する切断線Ｂのスライブ後にシリンダ３６の作用により前方で停止している第１ステージ２１の吸引ボックス３０をシリンダ３６により上昇させる。
【００３９】
すると、後方で停止している第２ステージ２３の吸引ボックス３０の下面に第１ステージ２１の液晶パネルＡが荷受けされ、荷受けされた液晶パネルＡを第２ステージ２３の吸引ボックス３０に吸引保持させる。
【００４０】
しかして、第２ステージ２３を前方に走行させ、第１折割装置Ｇの折割部材５５の直上に切断線Ｂが合致すると、第２ステージ２３の走行を停止し、次いで液晶パネルＡの下側Ｂ面に折割部材５５による加圧力や衝撃力を作用させて、切断線Ｂの浸透により折割する。
【００４１】
上記の折割が一方向の各切断線Ｂの終了後、第２ステージ２３を後退させ、また駆動手段３３により第２ステージ２３の９０°旋回後に第２ステージ２３を前進させ、かつ第１折割装置Ｇの前述の作用により他方向の各切断線Ｂを折割する。
【００４２】
上述のように、液晶パネルＡのＡ面の全ての切断線Ｂを折割したのち、第２ステージ２３を後方に走行させ、その走行途中に上昇させたカッタ４８により液晶パネルＡのＢ面に切断線Ｃをスライブする。
【００４３】
切断線Ｃをスライブしたカッタ４８は、降下し、その後に駆動手段３３により第２ステージ２３の吸引ボックス３０を９０°旋回させる。
【００４４】
その後に第２ステージ２３を前方に走行させ、走行途中にカッタ４８を上昇させて液晶パネルＡのＢ面に先の切断線Ｃに交差する切断線Ｃをスライブする。
【００４５】
上述のように、交差した切断線のスライブ後に、前進停止した第２ステージ２３の直下に後退停止している第３ステージ３１の吸引ボックス３０をシリンダ３６により上昇させる。
【００４６】
すると、第２ステージ２３の液晶パネルＡを第３ステージ３１に荷受けすると共に、第３ステージ３１の吸引ボックス３０に液晶パネルＡを保持する。
【００４７】
しかして、第３ステージ３１を間歇走行させ、第３ステージ３１の停止時に第１折割装置Ｇと同様に第２折割装置Ｈにより液晶パネルＡのＡ面に加圧力や衝撃力を作用させて一方向の切断線Ｃを折割し、次いで第３ステージ３１を９０°旋回させたのち、第２折割装置により他方向の切断線Ｃを折割する。
【００４８】
すると、図９に示すように、供給した液晶パネルＡのＡ面に交差する切断線Ｂを入れたのち、この交差する各切断線Ｂを順次折割し、次いで液晶パネルＡのＢ面に交差する切断線Ｃを入れたのち、この交差する各切断線Ｂを順次折割するので、反転による液晶パネルＡの裏返し工程が不要になる。
【００４９】
なお、第３ステージ３１で折割（液晶パネルＡから）された大割パネルから小割パネル（製品サイズ）の折割は、第３ステージ３１から荷受けして次工程で行なう。
【００５０】
この発明の第２の実施形態では、図１０から図１４に示すように、６１は、立て掛けた姿勢で供給された第１の実施形態と同様の液晶パネルＡを起立面に保持手段により保持して前後方向に走行すると共に、保持パネルＡを旋回させる旋回機能２２付の第１ステージである。
【００５１】
６２は、第１ステージ６１の前方で前後方向に走行すると共に、起立面に前進停止した第１ステージ６１の液晶パネルＡを起立状態に荷受けして保持手段により保持し、かつ保持液晶パネルＡを旋回させる旋回機能２２付の第２ステージである。
【００５２】
６３は、第２ステージ６２の前方で前後方向に走行すると共に、起立面に第２ステージ６２の液晶パネルＡを起立状態に荷受けして保持手段により保持し、かつ保持液晶パネルＡを旋回させる旋回機能２２付の第３ステージである。
【００５３】
上記第１ステージ６１、第２ステージ６２及び第３ステージ６３の前後方向のレール６４によりガイドされる自走手段、液晶パネルＡの保持手段、旋回機能、前進停止した第１ステージ６１から後退停止している第２ステージ６２に、又前進停止した第２ステージ６２から後退停止している第３ステージ６３に液晶パネルＡを荷受けさせるための供給（受け渡し）は、第１の実施形態と同様の手段や、機械的な入れ込み手段、人手などで行なう。
【００５４】
上記第１の実施形態と第２の実施形態との相違点は、第１の実施形態にあっては、液晶パネルＡを板面が水平な姿勢で、第２の実施形態にあっては、液晶パネルＡを板面が略垂直な（若干傾けて立て掛けた状態）姿勢で加することにある。
【００５５】
また、第１ステージ６１の走行路の途中には、第１ステージ６１に保持させてある液晶パネルＡの表側Ａ面に、第２ステージ６２の走行路の途中には、第２ステージ６２に保持させてある液晶パネルＡの表側Ｂ面に切断線Ｂ、Ｃを入れる第１切断装置Ｅ、第２切断装置Ｆが（図１１に示す）設けてある。
【００５６】
上記の第１切断装置Ｅ及び第２切断装置Ｆは、第１の実施形態と同様につき説明を省略する。
【００５７】
さらに、第２ステージ６２の走行路には、図１３に示すように第２ステージ６２に保持させてある液晶パネルＢの表側Ｂ面に作用（加圧力や衝撃を）させて切断線Ｂを折割（切断線Ｂを浸透させる）する第１折割装置Ｇが、第３ステージ６３の走行路の途中には、第３ステージ６３に保持させてある液晶パネルＡの表側Ａ面に作用（加圧力や衝撃を）させて、切断線Ｃを折割（切断線Ｃを浸透させる）する第２折割装置Ｈが設けてある。
【００５８】
上記の第１折割装置Ｇ及び第２折割装置Ｈは、第１の実施形態と同様につき説明を省略する。
【００５９】
次に、上記構成による液晶パネルＡの分断方法を図１４の工程図により説明する。
【００６０】
まず、後退停止している第１ステージ６１の吸引ボックス３０に人手や入れ込み機により液晶パネルＡを供給し、吸引ボックス３０内の吸引によって吸引ボックス３０に液晶パネルＡを保持する。
【００６１】
液晶パネルＡは、周知のように、二板の板ガラスを貼り合わせて形成されている。
【００６２】
次に、第１ステージ６１を前方に走行させる。
このとき、第１切断装置Ｅのカッタ４８により液晶パネルＡの表側Ａ面に並列する切断線Ｂをスライブ（入れる）する。
【００６３】
上記のスライブ後にカッタ４８を後退させ、次いで第１ステージ６１を後退させると共に、後退途中或いは後退後に駆動手段３３の運転により第１ステージ６１を９０°旋回させる。
【００６４】
然るのち、第１ステージ６１を再度前方に走行させると共に、走行途中に第１切断装置Ｅのカッタ４８により液晶パネルＡのＡ面に前の切断線Ｂに交差する切断線Ｂをスライブする。
【００６５】
交差する切断線Ｂのスライブ後に第１ステージ６１から第２ステージ６２に液晶パネルＡを荷渡し（人員的や機械的、例えばシリンダの伸長作用によって第１ステージ６１の吸引ボックス３０を突き出すなどにより）すると共に、第２ステージ６２の吸引ボックス３０に液晶パネルＡを吸引保持させる。
【００６６】
しかして、第２ステージ６２を前方に走行させ、第１折割装置Ｇの折割部材５５の直上に切断線Ｂが合致すると、第２ステージ６２の走行を停止し、次いで液晶パネルＡの表側Ｂ面に折割部材５５による加圧力や衝撃力を作用させて、切断線Ｂの浸透により折割する。
【００６７】
上記の折割が一方向の各切断線Ｂの終了後、第２ステージ６２を後退させ、また駆動手段３３により第２ステージ２３の９０°旋回後に第２ステージ６２を前進させ、かつ第１折割装置Ｇの前述の作用により他方向の各切断線Ｂを折割する。
【００６８】
上述のように、液晶パネルＡのＡ面の全ての切断線Ｂを折割したのち、第２ステージ６２を後方に走行させ、その走行途中に降下させたカッタ４８により液晶パネルＡのＢ面に切断線Ｃをスライブする。
【００６９】
切断線Ｃをスライブしたカッタ４８は、後退させ、その後に駆動手段３３により第２ステージ２３の吸引ボックス３０を９０°旋回させる。
【００７０】
その後に第２ステージ６２を前方に走行させ、走行途中に前進させたカッタ４８により液晶パネルＡのＢ面に先の切断線Ｃに交差する切断線Ｃをスライブする。
【００７１】
しかして、前進停止した第２ステージ６２から後退停止している第３ステージ６３に液晶パネルＢを荷渡し（第１ステージ６１から第２ステージ６２への荷渡しのように）、吸引ボックス３０に吸引保持させる。
【００７２】
然るのち、第３ステージ６３を間歇走行せさ、第３ステージ６３の停止時に第１折割装置Ｇと同様に第２折割装置Ｈに液晶パネルＡのＡ面に加圧力や衝撃力を作用させて順次一方向の切断線Ｃを、次いで他方向の切断線Ｃを（吸引ボックス３０の９０°旋回後）折割する。
【００７３】
すると、図１４に示すように、供給した液晶パネルＡのＡ面に交差する切断線Ｂを入れたのち、この交差する各切断線Ｂを順次折割し、次いで液晶パネルＡのＢ面に交差する切断線Ｃを入れたのち、この交差する各切断線Ｂを順次折割するので、反転による液晶パネルＡの裏返し工程が不要になる。
【００７４】
なお、第３ステージ６３で折割（液晶パネルＡから）された大割パネルから小割パネル（製品サイズ）の折割は、第３ステージ６３から荷受けして次工程で行なう。
【００７５】
【発明の効果】
以上のように、この発明の液晶パネルの分断システムによれば、供給した大判の液晶パネルのＡ面に交差する切断線をスライブし、このスライブした切断線を折割し、次いで液晶パネルのＢ面に交差する切断線をスライブし、このスライブした切断線を折割すると共に、上記の各作業を自動的に、かつ連続して行なうことができる。
【００７６】
特に、液晶パネルの次工程への受け渡しにパネルを反転しないために、総機長を著しく短かくすることができると共に、反転不要のため大判な液晶パネルの分断が可能になって一度に大量の製品サイズ（小割）の液晶パネルを得ることもできる。

BACKGROUND OF THE INVENTION
The present invention relates to a liquid crystal panel dividing system.
[0002]
[Prior art]
The liquid crystal panel is formed by bonding two plate glasses.
[0003]
As a conventional technique for dividing (dividing) such a liquid crystal panel into product sizes, as shown in FIG. 15, first, the liquid crystal panel A is supplied to the first stage 1 that travels in the front-rear direction or supplied by an insertion machine or the like. Then, the cutting line B is slived (inserted) into the A surface (one surface located on the upper surface) of the liquid crystal panel A on the first stage 1 by the cutter of the first cutting machine 11.
[0004]
In order to divide the cutting line B into a large part and a small part, the first stage 1 is turned 90 ° after the end of the sliver in one direction and slives in the other direction intersecting.
[0005]
Next, the slived liquid crystal panel A on the first stage 1 is supplied to the first inverting device 2 by an appropriate transfer means, and after the supply, the liquid crystal panel A is inverted 180 ° (sliced cutting line) by the first inverting device 2. (B is located on the lower surface).
[0006]
Then, after the inverted liquid crystal panel A is supplied onto the second stage 3 that travels in the front-rear direction by appropriate transfer means, the second stage 3 is intermittently traveled forward, and is moved up and down when the second stage 3 is stopped. A slived portion is sequentially broken by a first folding device 5 having a bar material or a roll folding member 4.
[0007]
The second stage 3 is turned 90 ° after splitting the sliver in one direction, and the sliver in the other direction is split as described above.
[0008]
After that, after the split liquid crystal panel A on the second stage 3 is supplied onto the third stage 7 traveling in the front-rear direction by an appropriate transfer means 6, the third stage 7 is cut by the cutter of the second cutting machine 8. A cutting line C is scribed on the B surface (the other surface located on the upper surface) of the upper liquid crystal panel A.
[0009]
The above-mentioned cutting line C coincides with the cutting line B on the A surface and, like the cutting line B, the third stage 7 is turned 90 ° after the end of the sliver in one direction in order to divide into a large part and a small part. And slive in the other direction that intersects.
[0010]
Next, the slived liquid crystal panel A on the third stage 7 is supplied to the second inverting device 9 by an appropriate transfer means, and after the supply, the liquid crystal panel A is inverted 180 ° (sliced cut) by the second inverting device 9. So that the line C is located on the lower surface).
[0011]

[Problems to be solved by the invention]
According to the system that divides the liquid crystal panel into product sizes as described above, the liquid crystal panel slived on the A side is the front first folding device, and the liquid crystal panel slived on the B side is the front second folding device.

A first cutting device E and a second cutting device F are provided on the lower side B surface of the panel A to put cutting lines B and C, respectively.
[0027]
As is well known (shown in FIGS. 2, 3, 4, and 6), the first cutting device E and the second cutting device F described above have a portal frame on the travel path of the first stage 21 and the second stage 23. 40, the slider 44 of the base 43 is slidably engaged with the horizontal rail 42 provided on the horizontal member 41 of the frame 40, and the rail 45 provided on the entire length of the base 43 is laid sideways.

You can adjust the movement.
[0029]
Further, below the travel path of the second stage 23, in front of the second cutting device F, the cutting line B is broken (permeated through the cutting line B) by acting on the B surface of the liquid crystal panel A. The second folding device H that splits the cutting line C (permeates the cutting line C) by causing the first folding device G to act on the A surface of the liquid crystal panel A in the middle of the travel path of the third stage 31. Is provided.
[0030]
As the first folding device G and the second folding device H, as shown in FIGS. 6, 7, and 8, a guide member 52 including a cylinder in a frame 51 and a shaft member penetrated through the cylinder. A support member 54 that is guided and guided up and down by a cylinder 53, and a folding member 55 that is horizontally mounted on the support member 53 (the illustrated folding member 55 uses a roll, but the cutting line B or It may be a bar material that applies a pressing force or a weak impact force to the cutting line C).
[0031]
In the figure, reference numeral 56 denotes an edge detection camera of the liquid crystal panel A. When the edge detected by the camera 56 is normally displaced from the position (on the line), the driving means 33 moves the first stage 21 and the second stage 23 together. Make a slight turn to correct the position (edge).
[0032]
Next, a method of dividing the liquid crystal panel A with the above configuration will be described with reference to the process diagram of FIG.
[0033]
First, the liquid crystal panel A is supplied onto the suction box 30 of the first stage 21 that has been retracted and stopped by hand or a inserting machine, and the liquid crystal panel A is held on the suction box 30 by suction in the suction box 30.
[0034]
As is well known, the liquid crystal panel A is formed by laminating two plate glasses.
[0035]
Next, the first stage 21 is moved forward.
At this time, the cutting line B parallel to the upper surface A of the liquid crystal panel A is slived (inserted) by the cutter 48 of the first cutting device E.
[0036]
After the sliver, the cutter 48 is raised and then the first stage 21 is moved backward, and the first stage 21 is turned 90 ° by the operation of the driving means 33 during or after the backward movement.
[0037]
After that, the first stage 21 is caused to travel forward again, and the cutting line B intersecting the previous cutting line B is slid on the A surface of the liquid crystal panel A by the cutter 48 of the first cutting device E during the traveling.
[0038]
After the slicing of the intersecting cutting lines B, the suction box 30 of the first stage 21 stopped in front by the action of the cylinder 36 is raised by the cylinder 36.
[0039]
Then, the liquid crystal panel A of the first stage 21 is received on the lower surface of the suction box 30 of the second stage 23 stopped at the rear, and the received liquid crystal panel A is sucked and held by the suction box 30 of the second stage 23. .
[0040]
Thus, when the second stage 23 is moved forward and the cutting line B is aligned directly above the folding member 55 of the first folding device G, the traveling of the second stage 23 is stopped, and then the lower side of the liquid crystal panel A The side B surface is subjected to a pressing force or an impact force by the folding member 55 and is broken by penetration of the cutting line B.
[0041]
After the end of each cutting line B in one direction, the second stage 23 is moved backward, and the second stage 23 is advanced after the second stage 23 is turned 90 ° by the driving means 33. Each cutting line B in the other direction is broken by the above-described action of the splitting device G.
[0042]
As described above, after all the cutting lines B on the A surface of the liquid crystal panel A are broken, the second stage 23 is moved backward, and the cutter 48 raised during the traveling is moved to the B surface of the liquid crystal panel A. Slive the cutting line C.
[0043]
The cutter 48 that has sliced the cutting line C descends, and thereafter, the driving means 33 rotates the suction box 30 of the second stage 23 by 90 °.
[0044]
Thereafter, the second stage 23 is caused to travel forward, the cutter 48 is raised during the travel, and the cutting line C that intersects the previous cutting line C is scribed on the B surface of the liquid crystal panel A.
[0045]
As described above, the suction box 30 of the third stage 31 that is retracted and stopped immediately below the second stage 23 that has been moved forward is raised by the cylinder 36 after the intersecting cutting lines are scribed.
[0046]
Then, the liquid crystal panel A of the second stage 23 is received by the third stage 31 and the liquid crystal panel A is held in the suction box 30 of the third stage 31.
[0047]
Accordingly, the third stage 31 is allowed to travel intermittently, and when the third stage 31 is stopped, the second folding device H applies pressure or impact force to the A surface of the liquid crystal panel A in the same manner as the first folding device G. After cutting the cutting line C in one direction and then turning the third stage 31 by 90 °, the cutting line C in the other direction is broken by the second folding device.
[0048]
Then, as shown in FIG. 9, cutting lines B intersecting with the A plane of the supplied liquid crystal panel A are inserted, and then the intersecting cutting lines B are sequentially broken, and then intersect with the B plane of the liquid crystal panel A. After the cutting line C to be inserted is inserted, the intersecting cutting lines B are sequentially broken, so that the process of turning the liquid crystal panel A over by reversal is unnecessary.
[0049]
It should be noted that the splitting of the large panel to the small panel (product size) which is split at the third stage 31 (from the liquid crystal panel A) is received from the third stage 31 and performed in the next process.
[0050]
In the second embodiment of the present invention, as shown in FIG. 10 to FIG. 14, 61 holds the liquid crystal panel A similar to that of the first embodiment supplied in a standing posture on the standing surface by the holding means. It is the 1st stage with the turning function 22 which makes the holding | maintenance panel A turn while running back and forth.
[0051]
62 runs in the front-rear direction in front of the first stage 61, receives the liquid crystal panel A of the first stage 61 that has advanced and stopped on the standing surface in a standing state, holds the liquid crystal panel A by the holding means, and holds the liquid crystal panel A It is the 2nd stage with the turning function 22 made to turn.
[0052]
63 is a swivel that travels in the front-rear direction in front of the second stage 62, holds the liquid crystal panel A of the second stage 62 on the standing surface in a standing state, holds it by the holding means, and turns the holding liquid crystal panel A. This is the third stage with function 22.
[0053]
The first stage 61, the second stage 62, and the third stage 63 are guided by the front-rear rails 64, the holding means for the liquid crystal panel A, the turning function, and the first stage 61 that has stopped moving forward is stopped. The supply (delivery) for receiving the liquid crystal panel A to the second stage 62 that has been moved forward and to the third stage 63 that has been moved backward and stopped from the second stage 62 that has been forwardly stopped is the same means as in the first embodiment. Or by mechanical means or manual operation.
[0054]
The difference between the first embodiment and the second embodiment is that in the first embodiment, the liquid crystal panel A is in a posture where the plate surface is horizontal, and in the second embodiment, The liquid crystal panel A is to be added in a posture in which the plate surface is substantially vertical (a state in which the liquid crystal panel A is slightly inclined and stood up).
[0055]
In the middle of the travel path of the first stage 61, it is held on the front side A surface of the liquid crystal panel A held on the first stage 61, and on the second stage 62 in the middle of the travel path of the second stage 62. A first cutting device E and a second cutting device F (shown in FIG. 11) are provided on the front side B surface of the liquid crystal panel A, which are provided with cutting lines B and C.
[0056]
The first cutting device E and the second cutting device F are the same as in the first embodiment, and a description thereof will be omitted.
[0057]
Further, on the traveling path of the second stage 62, as shown in FIG. 13, the cutting line B is folded by acting (pressing force or impact) on the front B surface of the liquid crystal panel B held by the second stage 62. The first folding device G that splits (permeates the cutting line B) acts on the front side A surface of the liquid crystal panel A held by the third stage 63 in the course of the travel path of the third stage 63 (additional). A second folding device H is provided to break the cutting line C (permeate the cutting line C) by applying pressure or impact).
[0058]
Since the first folding device G and the second folding device H are the same as those in the first embodiment, description thereof is omitted.
[0059]
Next, a method of dividing the liquid crystal panel A with the above configuration will be described with reference to the process diagram of FIG.
[0060]
First, the liquid crystal panel A is supplied to the suction box 30 of the first stage 61 that has been retracted and stopped manually or by a inserting machine, and the liquid crystal panel A is held in the suction box 30 by suction in the suction box 30.
[0061]
As is well known, the liquid crystal panel A is formed by laminating two plate glasses.
[0062]
Next, the first stage 61 is caused to travel forward.
At this time, the cutting line B parallel to the front side A surface of the liquid crystal panel A is slived (inserted) by the cutter 48 of the first cutting device E.
[0063]
After the sliver, the cutter 48 is moved backward, the first stage 61 is moved backward, and the first stage 61 is turned 90 ° by the operation of the driving means 33 during or after the backward movement.
[0064]
After that, the first stage 61 is caused to travel forward again, and the cutting line B intersecting the previous cutting line B is slid on the A surface of the liquid crystal panel A by the cutter 48 of the first cutting device E during the traveling.
[0065]
The liquid crystal panel A is delivered from the first stage 61 to the second stage 62 after the sliver of the intersecting cutting line B (personally or mechanically, for example, by pushing out the suction box 30 of the first stage 61 by the extension action of the cylinder). At the same time, the liquid crystal panel A is sucked and held in the suction box 30 of the second stage 62.
[0066]
Thus, when the second stage 62 is caused to travel forward and the cutting line B is aligned directly above the folding member 55 of the first folding device G, the traveling of the second stage 62 is stopped, and then the front side of the liquid crystal panel A The surface B is split by penetration of the cutting line B by applying a pressing force or impact force by the folding member 55.
[0067]
After the end of each cutting line B in one direction, the second stage 62 is moved backward, the second stage 62 is advanced by the drive means 33 after the second stage 23 is turned 90 °, and the first folding is performed. Each cutting line B in the other direction is broken by the above-described action of the splitting device G.
[0068]
As described above, after all the cutting lines B on the A surface of the liquid crystal panel A are broken, the second stage 62 is caused to travel backward, and the cutter 48 lowered during the travel is moved to the B surface of the liquid crystal panel A. Slive the cutting line C.
[0069]
The cutter 48 that has sliced the cutting line C is moved backward, and thereafter the suction means 30 of the second stage 23 is turned 90 ° by the driving means 33.
[0070]
After that, the second stage 62 is caused to travel forward, and the cutting line C that intersects the previous cutting line C is slived on the B surface of the liquid crystal panel A by the cutter 48 that is moved forward during the traveling.
[0071]
Accordingly, the liquid crystal panel B is delivered from the second stage 62 that has stopped moving forward to the third stage 63 that has stopped moving backward (as in the case of delivery from the first stage 61 to the second stage 62). Hold by suction.
[0072]
After that, the third stage 63 is made to run intermittently, and when the third stage 63 is stopped, the second folding device H is applied with pressure and impact force on the A surface of the liquid crystal panel A in the same manner as the first folding device G. Then, the cutting line C in one direction is sequentially broken, and then the cutting line C in the other direction is split (after the suction box 30 turns 90 °).
[0073]
Then, as shown in FIG. 14, after inserting the cutting lines B intersecting the A plane of the supplied liquid crystal panel A, the intersecting cutting lines B are sequentially broken and then intersecting the B plane of the liquid crystal panel A. After the cutting line C to be inserted is inserted, the intersecting cutting lines B are sequentially broken, so that the process of turning the liquid crystal panel A over by reversal is unnecessary.
[0074]
It should be noted that the splitting of the large panel to the small panel (product size) which is split at the third stage 63 (from the liquid crystal panel A) is received from the third stage 63 and performed in the next process.
[0075]
【The invention's effect】
As described above, according to the cutting system for a liquid crystal panel of the present invention, the cutting line that intersects the A plane of the supplied large-sized liquid crystal panel is sliced, the slicing cutting line is broken, and then the liquid crystal panel B It is possible to slive a cutting line that intersects the surface, break the slicing cutting line, and perform the above operations automatically and continuously.
[0076]
In particular, since the panel is not inverted for delivery to the next process of the liquid crystal panel, the total length of the machine can be shortened remarkably, and the large-sized liquid crystal panel can be divided because no reversal is required. A liquid crystal panel of size (small) can be obtained.
