ところで、特許文献１の切断装置は、パネルの表面（片面）のみに切断線を入れる方式である。   By the way, the cutting device of patent document 1 is a system which puts a cutting line only in the surface (one side) of a panel.

かりに、片面に切断線の加工ずみパネルを前進停止後のテーブル上から特許文献２の方式の人手や吸引方式などで取り上げ、取り上げ後に１８０°反転（裏返して）して、次工程のテーブル上に供給したのち、もう片面に切断線を入れることも考えられる。   As a matter of fact, the processed panel of the cutting line on one side is picked up by the manual or suction method of the method of Patent Document 2 from the table after the forward stop, and after picking up, it is turned 180 ° (turned over) and placed on the table of the next process. It is also possible to make a cutting line on the other side after feeding.

しかしながら、加工工程の機長が大幅に長くなると共に、大幅に設備費がアップし、又加工効率が著しく低下するなどの問題があった。   However, there is a problem that the machine length of the machining process is significantly increased, the equipment cost is greatly increased, and the machining efficiency is remarkably lowered.

特に、近時液晶パネルの軽量化にともないガラスの厚みが０．１〜０．３ｍｍを２枚貼り合わせたマザーガラスでより生産性を上げるため、マザーパネルも大型化し（９００ｍｍ×７３０ｍｍ）している。   In particular, the mother panel has been enlarged (900mm x 730mm) in order to increase the productivity with the mother glass in which two glass sheets with a thickness of 0.1 to 0.3mm are bonded together with the recent weight reduction of liquid crystal panels. Yes.

この大型な薄い液晶パネルを人手や吸引方式の反転機によって反転すると、反転時パネルのねじれなどにより破損などが発生する問題があった。   When the large thin liquid crystal panel is turned over manually or by a suction type reversing machine, there is a problem that the panel is damaged due to twisting of the panel at the time of turning over.

そこで、この発明の課題は、大型で、かつ薄い液晶パネルのＡ面及びＢ面に安全でしかも高効率に切断線を入れるようにしたことである。   SUMMARY OF THE INVENTION An object of the present invention is to provide cutting lines with safety and high efficiency on the A and B surfaces of a large and thin liquid crystal panel.

上記のような課題を解決するために、この発明は、載置した液晶パネルを吸引保持すると共に、進退走行手段により前後方向に走行するように設けたテーブルと、このテーブルに出没自在に貫通させて昇降手段により昇降自在に設けた上記液晶パネルの浮上用複数のピンと、上記テーブルの走行路の直上に上記液晶パネルの上側表面に切断線を入れるように設けたカッターと、上記テーブルの前進停止位置の前方に昇降手段により昇降するように設けた昇降体と、この昇降体に左右方向に伸び、かつ駆動手段により１８０°の反転回動するように設けた水平な回動アームと、この回動アームの両端から後方に突出すると共に、進退手段により接近、離反するように設けた開閉アームと、この両開閉アームから対向方向に並列して突出する下側に上記液晶パネルの側縁部下面を吸引する昇降機能付のパット及び上側に前記液晶パネルの側縁部上面に臨む落下止め部材とで構成した反転装置とからなり、上記落下止め部材を上記液晶パネルの上面と上面から外れる退避位置との間で移動するようにした構成を採用する。   In order to solve the above-described problems, the present invention is configured to suck and hold a placed liquid crystal panel and to travel in the front-rear direction by advancing / retreating means, and to allow the table to freely pass through the table. A plurality of pins for floating the liquid crystal panel provided so as to be movable up and down by an elevating means, a cutter provided so as to make a cutting line on the upper surface of the liquid crystal panel directly above the travel path of the table, and the forward stop of the table A lifting body provided so as to be moved up and down by a lifting means in front of the position, a horizontal rotating arm provided to the lifting body in the left-right direction and rotated 180 ° by the driving means, and An open / close arm that protrudes rearward from both ends of the moving arm and moves closer to and away from the advancing and retracting means, and a lower side that protrudes in parallel in the opposite direction from both open / close arms And a reversing device comprising a pad with an elevating function for sucking the lower surface of the side edge of the liquid crystal panel and an anti-drop member facing the upper surface of the side edge of the liquid crystal panel on the upper side. A configuration is adopted in which it moves between the upper surface and the retracted position deviating from the upper surface.

すると、テーブル上の液晶パネルのＡ面に切断線を入れたのち、テーブル上から取り上げた液晶パネルを反転して裏返してテーブル上に戻し、戻したテーブル上の液晶パネルのＢ面に切断線を入れる。   Then, after putting a cutting line on the A side of the liquid crystal panel on the table, the liquid crystal panel picked up from the table is reversed and turned over and returned to the table, and a cutting line is put on the B side of the liquid crystal panel on the returned table. Put in.

また、上記のテーブルが、旋回手段により旋回するようにした構成を採用する。
すると、液晶パネルのＡ面及びＢ面に交差した切断線が入る。 Further, a configuration is adopted in which the table is turned by turning means.
Then, a cutting line crossing the A surface and the B surface of the liquid crystal panel enters.

以上のように、この発明の液晶パネルの切断装置によれば、テーブル上に載置した液晶パネルのＡ面にテーブルの前進走行時カッターにより切断を入れ、テーブルの前進停止後に昇降手段により各ピンを上昇させてテーブル上の液晶パネルを浮上させ、次いで降下停止している回動アームの両端の両開閉アームを進退手段の作用により接近方向にスライドさせて閉じることで、浮上している液晶パネルの両側縁部の上下に上下の落下止め部材と吸引パットを嵌装させ、嵌装下に上昇させた各パットの吸引によって液晶パネルの両側縁の下面を吸着したのち、昇降手段の上昇作用にともない昇降体と共に回動アーム及び開閉アームを介し液晶パネルを上昇させ、次いで駆動手段の運転により１８０°回転させて液晶パネルを裏返し、パットにより吸着した状態で昇降体の降下作用により待機テーブル上に裏返した液晶パネルを載置（載置の以前に落下止め部材を邪魔にならない位置に退避させておく）し、載置後にテーブルを後退させ、次いで前進走行させながらテーブル上の液晶パネルのＢ面にカッターにより切断線を入れる。   As described above, according to the liquid crystal panel cutting device of the present invention, the surface A of the liquid crystal panel placed on the table is cut by the cutter when the table is moving forward, and each pin is moved by the lifting means after the table stops moving forward. Is lifted to lift the liquid crystal panel on the table, and then both open / close arms at the opposite ends of the pivoting arm that has been lowered and lowered are slid in the approaching direction by the action of the advancing / retreating means to close the liquid crystal panel The upper and lower drop stoppers and suction pads are fitted on the upper and lower sides of each side of the LCD panel, and the lower surfaces of both sides of the liquid crystal panel are adsorbed by the suction of each of the pads raised under the fitted state. Along with the lifting and lowering body, the liquid crystal panel is lifted through the rotating arm and the opening / closing arm, and then rotated 180 ° by the operation of the driving means so that the liquid crystal panel is turned over. Place the liquid crystal panel that is turned upside down on the standby table by the lowering action of the lifting body in the adsorbed state (with the anti-falling member retracted to an unobstructed position before placing), and retract the table after placing Then, a cutting line is made with a cutter on the B side of the liquid crystal panel on the table while traveling forward.

このため、液晶パネルの軽量化にともなう貼り合わせガラスの厚みが薄く、かつより生産性を上げるための大型（大判）なマザーパネルであってもねじれなどによる破損もなく極めて容易に液晶パネルのＡ面及びＢ面の両面に切断線を入れることができる。   For this reason, the thickness of the laminated glass accompanying the weight reduction of the liquid crystal panel is thin, and even if it is a large (large format) mother panel for higher productivity, it is extremely easy to avoid the damage due to twist or the like. Cutting lines can be made on both sides of the surface and the B surface.

また、旋回手段によりテーブルを旋回させることができるので、液晶パネルに交差する切断線を入れることができる。   Further, since the table can be turned by the turning means, a cutting line that intersects the liquid crystal panel can be entered.

上記の進退手段Ｊは、シリンダやアクチュエーターを使用する。 The driving means H is formed by a fourth motor 35 that drives the 180 ° reversal support shaft 34 of the open / close arms 22 and 22 by 180 °.
The advance / retreat means J uses a cylinder or an actuator.

上記の受け部材２６は、プレート３６の下面にローラを軸承したが、限定されず、落下を止める（受け止める）その他の部材を用いてもよい。   The receiving member 26 has a roller supported on the lower surface of the plate 36, but is not limited, and other members that stop (receive) the fall may be used.

上記のように構成すると、テーブルＢが前進停止したのち、昇降手段Ｄによって各ピン８を上昇させながら、テーブルＢ上の吸引保持の解除された液晶パネルＡを押し上げて浮上（図３中１点鎖線に示すように）させる。   With the configuration described above, after the table B is moved forward and stopped, the liquid crystal panel A released from the suction and holding on the table B is pushed up and lifted while the pins 8 are lifted by the lifting means D (one point in FIG. 3). (As indicated by the chain line).

次に、反転装置Ｅの互いに開いて降下停止している両開閉アーム２２、２２を進退手段Ｊの作用により内方に向け（閉じる方向）スライドさせて、図４に示すように液晶パネルＡ両側縁部下面下にパット２４を、両側縁部上面に受け部材２６を位置させる。
このとき、ピン８とパット２４とは、衝突しないように配置位置が考慮されている。 Next, the two open / close arms 22 and 22 of the reversing device E which are opened and stopped from each other are slid inwardly (in the closing direction) by the action of the advancing / retreating means J, so that both sides of the liquid crystal panel A as shown in FIG. The pad 24 is positioned below the lower edge of the edge, and the receiving member 26 is positioned on the upper surface of both side edges.
At this time, the arrangement position of the pin 8 and the pad 24 is considered so as not to collide.

その後に、シリンダ２３の伸長作用により液晶パネルＡの両側縁部下面に各パット２４を押し付けて吸引する。   Thereafter, the pads 24 are pressed against the lower surfaces of both side edges of the liquid crystal panel A by the extending action of the cylinder 23 and sucked.

しかして、昇降手段Ｆを上昇運転することによりパット２４により吸引保持された液晶パネルＡを反転位置迄持ち上げる。   Thus, by raising and lowering the elevating means F, the liquid crystal panel A sucked and held by the pad 24 is raised to the reverse position.

その後に駆動手段Ｈにより、図７に示すように両開閉アーム２２、２２と共に液晶パネルＡを１８０°反転させる（裏返す）。   Thereafter, the liquid crystal panel A together with the two open / close arms 22 and 22 is inverted by 180 ° by the driving means H as shown in FIG.

反転後に昇降手段Ｆを降下運転して両開閉アーム２２、２２と共に、液晶パネルＡを降送する。   After the reversal, the elevating means F is lowered and the liquid crystal panel A is moved down together with the open / close arms 22 and 22.

上記液晶パネルＡの降送にともないテーブルＢ上に液晶パネルＡが到達前に進退移動手段２５により受け部材２６をテーブルＢ上に衝突しないように退避（図８に示すように）させておく。   As the liquid crystal panel A descends, the receiving member 26 is retracted (as shown in FIG. 8) by the advancing / retreating means 25 so as not to collide with the table B before the liquid crystal panel A reaches the table B.

このとき、図８に示すように液晶パネルＡは、パット２４により吸引保持してあるので、保持状態を維持しながら、安定よくテーブルＢ上に液晶パネルＡを載置し、載置後にパット２４の吸引を解除し、テーブルＢ上の液晶パネルＡは、テーブルＢ上に吸引保持させる。   At this time, as shown in FIG. 8, since the liquid crystal panel A is sucked and held by the pad 24, the liquid crystal panel A is stably placed on the table B while maintaining the holding state, and the pad 24 is placed after placement. The liquid crystal panel A on the table B is sucked and held on the table B.

その後にテーブルＢを後退停止させたのち、テーブルＢを前進走行させて、液晶パネルＡのＢ面にカッター１３により切断線を入れる。
図中４１はテーブルＢに設けてあるピン８の貫通孔である。 Thereafter, after the table B is moved backward and stopped, the table B is moved forward, and a cutting line is made on the B surface of the liquid crystal panel A by the cutter 13.
In the figure, reference numeral 41 denotes a through hole of the pin 8 provided in the table B.

この発明の第２の実施形態では、前述のテーブルＢが旋回手段Ｋにより旋回するようになっている。   In the second embodiment of the present invention, the table B described above is turned by the turning means K.

上記の旋回手段Ｋは、図示の場合、座板１１の中心回転軸５１に旋回モーター５２の回動出力軸を接続したが、限定されず、例えば回転軸の歯車にモーターに可逆駆動される歯車を噛み合わせて（図示省略）旋回させることもある。   In the illustrated case, the turning means K has a rotation output shaft of the turning motor 52 connected to the central rotation shaft 51 of the seat plate 11, but is not limited thereto, for example, a gear that is reversibly driven by the motor to a gear of the rotation shaft. May be swung (not shown).

すると、旋回手段ＫによりテーブルによりテーブルＢを９０°旋回させて、液晶パネルＡに交差する切断線を入れることができる。   Then, the table B can be turned 90 ° by the turning means K by the table, and a cutting line intersecting the liquid crystal panel A can be entered.

なお、上記の旋回手段Ｋは、周知のようにテーブルＢの走行路の上方カメラ（図示せず）を設けて、このカメラによって液晶パネルのアライメント印を読み取って、この読み取りにともない数値制御により旋回手段ＫによりテーブルＢを時計、反時計方向にアライメントに応じた角度回動させることもできる。   As is well known, the turning means K is provided with an upper camera (not shown) on the traveling path of the table B, reads the alignment mark of the liquid crystal panel with this camera, and turns by numerical control along with this reading.
