  • the conventional manufacturing system has a problem that the production efficiency of the optical display panel is insufficient.
  • an unwinding portion for fixing the original roll of the polarizing film is provided at one location. Therefore, when replacing the used raw roll, the operator first stops the production system line. Next, the unwinding part is moved horizontally in the core direction of the original roll. Then, an operator will perform exchange work by bonding a used original fabric roll and a new original fabric roll in a film edge part in the unwinding part moved horizontally.

  • the polarizing films can be immediately connected to each other, and the replaced polarizing film can be unwound quickly. Therefore, since the time required for the replacement work of the raw roll of the unwinding part can be reduced, the manufacturing time of the optical display device can be shortened.
  • the unwinding part can move horizontally with respect to the core direction of the polarizing film. For this reason, when exchanging a polarizing film, the roll of a new polarizing film can be installed in the unwinding part moved to the said horizontal direction. Therefore, unlike a laminating machine having a turret, the unwinding portion does not move upward. For this reason, the range which an unwinding part moves can be made small, and the manufacturing system reduced in size can be provided.

Description

光学表示装置の製造システムおよび当該光学表示装置の製造方法Optical display device manufacturing system and optical display device manufacturing method
　本発明は、光学表示装置の製造システムおよび当該光学表示装置の製造方法に関するものである。 The present invention relates to an optical display device manufacturing system and an optical display device manufacturing method.
　従来、液晶パネルに偏光フィルムが貼合された光学表示パネルが広く製造されている。液晶パネルと偏光フィルムとを貼合する際には、長尺のロール偏光フィルムを巻き出し、枚葉状の液晶パネルとの貼合を行う製造システムが提案されている。 Conventionally, an optical display panel in which a polarizing film is bonded to a liquid crystal panel has been widely manufactured. When bonding a liquid crystal panel and a polarizing film, the manufacturing system which unwinds a long roll polarizing film and bonds with a sheet-like liquid crystal panel is proposed.
　例えば、特許文献１および特許文献２には、光学フィルムを貼合する装置が開示されている。これらの装置によれば、作業効率良く光学フィルムの貼合が可能である。 For example, Patent Literature 1 and Patent Literature 2 disclose an apparatus for laminating an optical film. According to these apparatuses, the optical film can be bonded with high work efficiency.
　また、特許文献３には、複数の原反ロールをターレットによって紙継ぎするラミネート加工機が開示されている。 Further, Patent Document 3 discloses a laminating machine that joins a plurality of raw rolls with a turret.

　しかしながら、上記従来の製造システムでは、光学表示パネルの生産効率が不十分であるという問題点を有している。 However, the conventional manufacturing system has a problem that the production efficiency of the optical display panel is insufficient.
　具体的に説明すると、特許文献１および特許文献２に開示された製造システムでは、偏光フィルムの原反ロールを固定する巻出部が１箇所に備えられている。従って、使用済みの原反ロールを交換する際、まず、オペレーターは製造システムのラインを停止させる。次に、巻出部を原反ロールの巻芯方向に水平に移動させる。その後、オペレーターは、水平移動した巻出部において使用済み原反ロールと新しい原反ロールとをフィルム端部にて貼合することによって交換作業を行うこととなる。 More specifically, in the manufacturing system disclosed in Patent Document 1 and Patent Document 2, an unwinding portion for fixing the original roll of the polarizing film is provided at one location. Therefore, when replacing the used raw roll, the operator first stops the production system line. Next, the unwinding part is moved horizontally in the core direction of the original roll. Then, an operator will perform exchange work by bonding a used original fabric roll and a new original fabric roll in a film edge part in the unwinding part moved horizontally.
　すなわち、巻出部を原反ロールの巻芯方向に水平移動させた後に原反ロールの交換作業を行う必要があるため、交換作業に多大な時間を要する。その結果、光学表示パネル１枚当りの製造時間が長時間必要となり、生産効率の低下を招いていた。 That is, since it is necessary to perform the work of replacing the original roll after the unwinding portion has been moved horizontally in the direction of the core of the original roll, the replacement work takes a lot of time. As a result, the manufacturing time per optical display panel is required for a long time, resulting in a decrease in production efficiency.
　また、特許文献３に記載のラミネート加工機では、原反ロールをターレットによって紙継ぎする。このような方式を光学表示パネルの製造システムに採用した場合、ターレットを設置するために広い設置場所が必要となる。このため、紙継ぎ時には、ターレットが回転するための空間を確保する必要が生じ、製造システムが大型化することとなる。 In the laminating machine described in Patent Document 3, the original roll is spliced with a turret. When such a method is adopted in an optical display panel manufacturing system, a large installation place is required to install the turret. For this reason, at the time of paper joining, it is necessary to secure a space for the turret to rotate, and the manufacturing system is increased in size.
　本発明は、上記従来の問題点に鑑みなされたものであって、その目的は、光学表示装置の製造時間を短縮することができ、小型化された光学表示装置の製造システムを提供することにある。 The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a manufacturing system for a miniaturized optical display device that can shorten the manufacturing time of the optical display device. is there.
　本発明の光学表示装置の製造システムは、上記課題を解決するために、液晶パネルに偏光フィルムを貼合して光学表示装置を製造する製造システムであって、保護フィルムによって表面が保護された偏光フィルムを巻出す巻出部と、上記偏光フィルムから保護フィルムを剥離する剥離部と、液晶パネルを貼合部へ搬送する搬送機構と、上記液晶パネル、および、保護フィルムが剥離された偏光フィルムを貼合する貼合部と、上記偏光フィルムから剥離された保護フィルムを巻取る巻取部とを備えており、上記巻出部は、偏光フィルムの巻芯方向に対して水平に移動可能であり、上記巻出部である第１巻出部および第２巻出部が並設されている。 In order to solve the above-mentioned problems, the optical display device manufacturing system of the present invention is a manufacturing system for manufacturing an optical display device by laminating a polarizing film on a liquid crystal panel, and the surface of which is protected by a protective film. An unwinding part for unwinding the film, a peeling part for peeling the protective film from the polarizing film, a transport mechanism for transporting the liquid crystal panel to the bonding part, the polarizing panel from which the liquid crystal panel and the protective film are peeled off It has a laminating part for pasting and a winding part for winding up the protective film peeled off from the polarizing film, and the unwinding part can move horizontally with respect to the core direction of the polarizing film. The first unwinding portion and the second unwinding portion, which are the unwinding portions, are arranged in parallel.
　上記製造システムでは、第１巻出部および第２巻出部の２つの巻出部が備えられており、偏光フィルムのロールを新たなロールに交換せずとも、第１巻出部および第２巻出部の偏光フィルムを用いて即座に偏光フィルム同士を連結させることができ、速やかに交換した偏光フィルムを巻き出すことができる。したがって、巻出部の原反ロールの交換作業に必要な時間を削減することができる為、光学表示装置の製造時間を短縮することが可能である。 In the manufacturing system, the two unwinding portions, the first unwinding portion and the second unwinding portion, are provided, and the first unwinding portion and the second unwinding portion are replaced without replacing the roll of the polarizing film with a new roll. Using the polarizing film at the unwinding portion, the polarizing films can be immediately connected to each other, and the replaced polarizing film can be unwound quickly. Therefore, since the time required for the replacement work of the raw roll of the unwinding part can be reduced, the manufacturing time of the optical display device can be shortened.
　また、上記巻出部は、偏光フィルムの巻芯方向に対して水平に移動可能である。このため、偏光フィルムを交換する場合、上記水平方向に移動された巻出部に新たな偏光フィルムのロールを設置することができる。したがって、ターレットを有するラミネート加工機とは異なり、巻出部は上方に向かって移動しない。このため、巻出部の移動する範囲を小さくすることができ、小型化された製造システムを提供することができる。 Further, the unwinding part can move horizontally with respect to the core direction of the polarizing film. For this reason, when exchanging a polarizing film, the roll of a new polarizing film can be installed in the unwinding part moved to the said horizontal direction. Therefore, unlike a laminating machine having a turret, the unwinding portion does not move upward. For this reason, the range which an unwinding part moves can be made small, and the manufacturing system reduced in size can be provided.
　本発明の光学表示装置の製造システムは、以上のように液晶パネルに偏光フィルムを貼合して光学表示装置を製造する製造システムであって、保護フィルムによって表面が保護された偏光フィルムを巻出す巻出部と、上記偏光フィルムから保護フィルムを剥離する剥離部と、液晶パネルを貼合部へ搬送する搬送機構と、上記液晶パネル、および、保護フィルムが剥離された偏光フィルムを貼合する貼合部と、上記偏光フィルムから剥離された保護フィルムを巻取る巻取部とを備えており、上記巻出部は、偏光フィルムの巻芯方向に対して水平に移動可能であり、上記巻出部である第１巻出部および第２巻出部が並設されているものである。 The optical display device manufacturing system of the present invention is a manufacturing system for manufacturing an optical display device by bonding a polarizing film to a liquid crystal panel as described above, and unwinds a polarizing film whose surface is protected by a protective film. An unwinding unit, a peeling unit for peeling the protective film from the polarizing film, a transport mechanism for transporting the liquid crystal panel to the bonding unit, a bonding unit for bonding the polarizing film from which the liquid crystal panel and the protective film have been peeled off A winding portion for winding the protective film peeled off from the polarizing film, and the unwinding portion is movable horizontally with respect to the core direction of the polarizing film, The 1st unwinding part and 2nd unwinding part which are parts are arranged in parallel.
　それゆえ、偏光フィルムのロールを新たなロールに交換せずとも、第１巻出部および第２巻出部の偏光フィルムを用いて即座に偏光フィルム同士を連結させることができ、速やかに交換した偏光フィルムを巻き出すことができる。したがって、巻出部の原反ロールの交換作業に必要な時間を削減することができる為、光学表示装置の製造時間を短縮することができる。また、上記巻出部は、偏光フィルムの巻芯方向に対して水平に移動可能である。このため、偏光フィルムを交換する場合、上記水平方向に移動された巻出部に新たな偏光フィルムのロールを設置することができる。したがって、ターレットを有するラミネート加工機とは異なり、巻出部は上方に向かって移動しない。このため、巻出部の移動する範囲を小さくすることができ、小型化された製造システムを提供することができるという効果を奏する。 Therefore, without changing the roll of the polarizing film to a new roll, the polarizing films can be immediately connected to each other using the polarizing films of the first unwinding portion and the second unwinding portion, and the polarizing film is quickly replaced. A polarizing film can be unwound. Therefore, since the time required for the replacement work of the raw roll of the unwinding part can be reduced, the manufacturing time of the optical display device can be shortened. Moreover, the said unwinding part can move horizontally with respect to the core direction of a polarizing film. For this reason, when exchanging a polarizing film, the roll of a new polarizing film can be installed in the unwinding part moved to the said horizontal direction. Therefore, unlike a laminating machine having a turret, the unwinding portion does not move upward. For this reason, it is possible to reduce the range in which the unwinding part moves and to provide an effect that a miniaturized manufacturing system can be provided.

　本発明の一実施形態について図１ないし図５に基づいて説明すれば、以下の通りである。 An embodiment of the present invention will be described with reference to FIGS. 1 to 5 as follows.
　〔光学表示装置の製造システムの構成〕
　図１は、本発明に係る光学表示装置の製造システム３０を示す断面図である。製造システム３０は、偏光フィルム１０または２０と、液晶パネル２とを貼合するものである。液晶パネル２としては、公知の液晶パネルを用いればよく、ガラス基板などの基板と液晶層との間に配向膜を配した公知の液晶パネルが挙げられる。 [Configuration of optical display device manufacturing system]
FIG. 1 is a cross-sectional view showing an optical display device manufacturing system 30 according to the present invention. The manufacturing system 30 bonds the polarizing film 10 or 20 and the liquid crystal panel 2 together. As the liquid crystal panel 2, a known liquid crystal panel may be used, and a known liquid crystal panel in which an alignment film is disposed between a substrate such as a glass substrate and a liquid crystal layer may be used.
　図１に示すように、製造システム３０の各構成として、巻出部（第１巻出部）１、巻出部（第２巻出部）１１、フィルム連結部（第１フィルム連結部）３、フィルム連結部（第２フィルム連結部）１３および搬送機構１２が備えられている。また、図２に示すように、ナイフエッジ（剥離部）２３およびニップロール２２・２２ａ（本明細書において「・」は「および」を意味する）が備えられている。 As shown in FIG. 1, each component of the manufacturing system 30 includes an unwinding part (first unwinding part) 1, an unwinding part (second unwinding part) 11, and a film connecting part (first film connecting part) 3. , A film connecting part (second film connecting part) 13 and a transport mechanism 12 are provided. Further, as shown in FIG. 2, a knife edge (peeling portion) 23 and nip rolls 22 and 22a (in the present specification, “·” means “and”) are provided.
　巻出部１および巻出部１１は、偏光フィルム１０・２０のロールをそれぞれ保持する装置であり、偏光フィルム１０・２０へ加えられる張力を調整可能な構成となっている。巻出部１から巻き出された偏光フィルム１０は、各ガイドロールを介してライン側に送られる。巻出部１１から巻き出される偏光フィルム２０についても同様である。 The unwinding part 1 and the unwinding part 11 are apparatuses that respectively hold the rolls of the polarizing films 10 and 20, and are configured to be able to adjust the tension applied to the polarizing films 10 and 20. The polarizing film 10 unwound from the unwinding part 1 is sent to the line side through each guide roll. The same applies to the polarizing film 20 unwound from the unwinding section 11.
　巻出部１および巻出部１１は並設されている。また、巻出部１および巻出部１１は、偏光フィルム１０・２０の巻芯１ａ・１１ａの方向にそれぞれ水平な方向に移動可能な構造となっている。換言すると、巻出部１は、偏光フィルム１０の幅方向に移動可能であり、巻出部１１は、偏光フィルム２０の幅方向に移動可能な構造となっている。より具体的には、図１の左側に示すように、巻芯１ａ・１１ａに沿った両方向の少なくとも一方に移動可能な構造となっている（図面奥側方向（○中に×のマーク）および図面手前側方向（○中に・のマーク）の少なくとも一方に移動可能）。このため、偏光フィルム１０または２０の残量が少なくなると、巻出部１または巻出部１１はオペレーターによって上記巻芯方向に水平に移動され、偏光フィルムのロールは新たなロールに交換される。 Unwinding part 1 and unwinding part 11 are arranged side by side. Moreover, the unwinding part 1 and the unwinding part 11 have a structure which can move to a horizontal direction, respectively in the direction of the core 1a * 11a of the polarizing films 10 * 20. In other words, the unwinding part 1 can move in the width direction of the polarizing film 10, and the unwinding part 11 has a structure that can move in the width direction of the polarizing film 20. More specifically, as shown on the left side of FIG. 1, it is structured to be movable in at least one of both directions along the cores 1a and 11a (the rear side direction in the drawing (marked with x in the circle)) and It can be moved to the front side of the drawing (movable to at least one of the marks in the circle). For this reason, when the remaining amount of the polarizing film 10 or 20 decreases, the unwinding unit 1 or the unwinding unit 11 is moved horizontally in the winding core direction by the operator, and the roll of the polarizing film is replaced with a new roll.
　上記構成のため、偏光フィルムを交換する場合、上記水平方向に移動された巻出部に新たな偏光フィルムのロールを設置することができる。したがって、ターレットを有するラミネート加工機とは異なり、巻出部１・１１は上方に向かって移動しない。このため、巻出部の移動する範囲を小さくすることができ、小型化された製造システムを提供することができる。 For the above configuration, when the polarizing film is exchanged, a new polarizing film roll can be installed on the unwinding portion moved in the horizontal direction. Therefore, unlike the laminating machine having a turret, the unwinding portions 1 and 11 do not move upward. For this reason, the range which an unwinding part moves can be made small, and the manufacturing system reduced in size can be provided.
　特に、巻出部１・１１が水平方向に移動するため、巻出部１・１１と搬送機構１２との間に巻出部１・１１が移動するための空間を必要としない。その結果、巻出部１・１１と搬送機構１２との間の空間を小さくすることができ、製造システム３０の小型化を図ることができる。本願発明は、このような小型化が達成できる点でターレットを有する従来の製造システムと大きく異なっている。 Particularly, since the unwinding units 1 and 11 move in the horizontal direction, a space for moving the unwinding units 1 and 11 between the unwinding units 1 and 11 and the transport mechanism 12 is not required. As a result, the space between the unwinding units 1 and 11 and the transport mechanism 12 can be reduced, and the manufacturing system 30 can be reduced in size. The present invention is greatly different from a conventional manufacturing system having a turret in that such downsizing can be achieved.
　上記偏光フィルム１０・２０としては公知の偏光フィルムを用いればよい。本発明における偏光フィルムは通常長尺の偏光フィルムが使用される。具体的には、偏光子フィルムの両面に保護フィルムとしてＴＡＣ（トリアセチルセルロース）フィルム等が貼合されており、さらに一方または両方のＴＡＣフィルムに粘着剤を介して、保護フィルムが積層された構成となっている。偏光フィルム１０のうち、中心に位置する偏光子フィルムとしては、ポリビニルアルコールフィルムにヨウ素等によって染色がなされており、延伸されたフィルム等にＴＡＣなどの保護フィルムが貼合されたフィルムを挙げることができる。また、上記ポリビニルアルコールフィルムに代えて、部分ホルマール化ポリビニルアルコール系フィルム、エチレン・酢酸ビニル共重合体系部分ケン化フィルム、セルロース系フィルム等の親水性高分子フィルム等、ポリビニルアルコールの脱水処理物やポリ塩化ビニルの脱塩酸処理物等のポリエン配向フィルム等を使用することもできる。 As the polarizing films 10 and 20, a known polarizing film may be used. As the polarizing film in the present invention, a long polarizing film is usually used. Specifically, a TAC (triacetylcellulose) film or the like is bonded as a protective film on both sides of the polarizer film, and a protective film is laminated on one or both TAC films via an adhesive. It has become. Among the polarizing films 10, examples of the polarizer film located in the center include a film in which a polyvinyl alcohol film is dyed with iodine or the like, and a protective film such as TAC is bonded to the stretched film or the like. it can. Also, instead of the polyvinyl alcohol film, a partially formalized polyvinyl alcohol film, an ethylene / vinyl acetate copolymer partially saponified film, a hydrophilic polymer film such as a cellulose film, etc. Polyene-oriented films such as vinyl chloride dehydrochlorinated products can also be used.
　偏光フィルム１０および保護フィルムを含めた総厚さは、特に限定されないが、１００μｍ以上、５００μｍ以下とすることができる。なお、偏光フィルム１０のうち偏光子フィルムの厚さは、概して１０μｍ以上、５０μｍ以下である。さらに、偏光フィルム１０の実用上、問題ない範囲にて上記３層以外にさらに他の層を含んでいてもよい。 The total thickness including the polarizing film 10 and the protective film is not particularly limited, but can be 100 μm or more and 500 μm or less. In addition, the thickness of the polarizer film in the polarizing film 10 is generally 10 μm or more and 50 μm or less. Furthermore, in addition to the above three layers, other layers may be included within the practical range of the polarizing film 10.
　図１では図示しないが、上記偏光フィルムはその表面が保護フィルムによって保護されている。偏光フィルム１０と保護フィルムとの間には、粘着剤層が存在しており、保護フィルムが剥離された後に粘着剤層を介して偏光フィルム１０と液晶パネル２とが貼合される。上記保護フィルムは、偏光フィルム１０の片面に備えられた構成としているが、両面に備えられていてもよい。 Although not shown in FIG. 1, the surface of the polarizing film is protected by a protective film. An adhesive layer is present between the polarizing film 10 and the protective film, and the polarizing film 10 and the liquid crystal panel 2 are bonded through the adhesive layer after the protective film is peeled off. Although the said protective film is set as the structure provided in the single side | surface of the polarizing film 10, you may be provided in both surfaces.
　上記保護フィルムとしては、ポリエステルフィルム、ポリエチレンテレフタラートフィルムなどを用いることができる。また、上記保護フィルムの厚さおよび幅としては、特に限定されるものではないが、偏光フィルムの保護フィルムとして用いられる観点から、例えば、５μｍ以上、５０μｍ以下の厚さ、２００ｍｍ以上、１５００ｍｍ以下の幅の保護フィルムを好ましく用いることができる。 As the protective film, a polyester film, a polyethylene terephthalate film, or the like can be used. In addition, the thickness and width of the protective film are not particularly limited, but from the viewpoint of being used as a protective film for a polarizing film, for example, a thickness of 5 μm or more and 50 μm or less, 200 mm or more and 1500 mm or less. A protective film having a width can be preferably used.
　搬送機構１２は、偏光フィルム１０（または２０）との貼合がなされるニップロール（貼合部）２２・２２ａまで液晶パネル２を運搬するものである。搬送機構１２は、偏光フィルム１０の流れ方向に向かって配置されていると共に、偏光フィルム１０の上方に配置されている。このように、下段の巻出部１・１１、フィルム連結部３・１３、ナイフエッジ２３の上段に搬送機構１２およびニップロール２２・２２ａが配置されている。このように、各部材が上下段に沿って配置されているため、製造システム３０は省スペースな構造となっている。 The transport mechanism 12 transports the liquid crystal panel 2 to nip rolls (bonding portions) 22 and 22a that are bonded to the polarizing film 10 (or 20). The transport mechanism 12 is disposed in the flow direction of the polarizing film 10 and is disposed above the polarizing film 10. As described above, the transport mechanism 12 and the nip rolls 22 and 22a are arranged on the upper stages of the lower unwinding sections 1 and 11, the film connecting sections 3 and 13, and the knife edge 23. Thus, since each member is arrange | positioned along the up-and-down stage, the manufacturing system 30 has a space-saving structure.
　製造システム３０での搬送機構１２は、ローラー形状の構造となっているが、搬送機構１２としては、液晶パネルを運搬することができればよく、ローラー形状に限定されるものではない。搬送機構１２によって液晶パネル２が図中、左側から右側（ニップロール２２・２２ａ側）へと搬送される。なお、フィルム連結部３・１３、および、図１では図示しない切断機については後述する。 The transport mechanism 12 in the manufacturing system 30 has a roller-shaped structure, but the transport mechanism 12 is not limited to the roller shape as long as the liquid crystal panel can be transported. The liquid crystal panel 2 is transported from the left side to the right side (nip rolls 22 and 22a side) in the figure by the transport mechanism 12. The film connecting portions 3 and 13 and a cutting machine not shown in FIG. 1 will be described later.
　次に、図２を用いて偏光フィルム１０と液晶パネル２との貼合について説明する。図２は、ニップロール２２・２２ａ付近の製造システム３０の構造を示す断面図である。図２に示すように、偏光フィルム１０は切断されており、粘着剤層を介して保護フィルムに付着している。すなわち、偏光フィルム１０はニップロール２２・２２ａに到達する前段階において、図示しないハーフカッターによって、液晶パネル２と貼合するに好ましいサイズにカットされる。一方、保護フィルム１０ａはカットされない。 Next, the bonding of the polarizing film 10 and the liquid crystal panel 2 will be described with reference to FIG. FIG. 2 is a sectional view showing the structure of the manufacturing system 30 near the nip rolls 22 and 22a. As shown in FIG. 2, the polarizing film 10 is cut and attached to the protective film via the pressure-sensitive adhesive layer. That is, the polarizing film 10 is cut to a size preferable for bonding to the liquid crystal panel 2 by a half cutter (not shown) in the stage before reaching the nip rolls 22 and 22a. On the other hand, the protective film 10a is not cut.
　また、保護フィルム１０ａに沿ってナイフエッジ２３が配置されている。ナイフエッジ２３はその側面の形状として三角形形状を有しており、ナイフエッジ２３の底面は保護フィルム１０ａの巻き出し方向に沿って配置されている。ナイフエッジ２３は、ナイフエッジ２３および保護フィルム１０ａ間の摩擦力が小さく、保護フィルム１０ａが粘着剤層から容易に剥離することができる部材、例えばダイヤモンドライクカーボン等で表面加工された部材で構成されている。これにより、保護フィルム１０ａはナイフエッジ２３に追随して移動することによって偏光フィルム１０から剥離し、除去され、その後、図示しない巻取部に巻き取られる。このようなナイフエッジ２３の材料としては、例えば、ＳＵＳ３０４、ＳＵＳ４２０などが挙げられる。 Further, a knife edge 23 is arranged along the protective film 10a. The knife edge 23 has a triangular shape as its side surface, and the bottom surface of the knife edge 23 is arranged along the unwinding direction of the protective film 10a. The knife edge 23 is composed of a member having a small frictional force between the knife edge 23 and the protective film 10a and capable of easily peeling the protective film 10a from the pressure-sensitive adhesive layer, for example, a member whose surface is processed with diamond-like carbon or the like. ing. Thereby, the protective film 10a is peeled off and removed from the polarizing film 10 by moving following the knife edge 23, and then wound around a winding portion (not shown). Examples of the material for the knife edge 23 include SUS304 and SUS420.
　上記巻取部は、保護フィルム１０ａを巻取る装置であり、基本的な構造は巻出部１または１１と同様である。なお、２つの巻取部が備えられており、後述するように、２つのフィルム連結部によって偏光フィルムの連結を行うように、保護フィルム１０ａの連結を２つのフィルム連結部によって行う構成とすることもできる。 The winding unit is a device that winds the protective film 10a, and the basic structure is the same as that of the unwinding unit 1 or 11. In addition, it is set as the structure which is provided with two winding parts, and connects the protective film 10a with two film connection parts so that a polarizing film may be connected with two film connection parts so that it may mention later. You can also.
　ニップロール２２・２２ａは、搬送機構１２によって搬送された液晶パネル２と、偏光フィルム１０とを圧着して貼合するものである。ニップロール２２・２２ａにおける貼合時の圧力は適宜調整すればよい。 The nip rolls 22 and 22a are for bonding the liquid crystal panel 2 transported by the transport mechanism 12 and the polarizing film 10 by pressure bonding. What is necessary is just to adjust the pressure at the time of bonding in the nip rolls 22 and 22a suitably.
　図３は、フィルム連結部３および切断機７を示す斜視図である。図３に示すように、フィルム連結部３は、吸着部４・４ａおよび切断貼合部５を備えている。 FIG. 3 is a perspective view showing the film connecting portion 3 and the cutting machine 7. As shown in FIG. 3, the film connecting portion 3 includes adsorption portions 4 and 4 a and a cutting and bonding portion 5.
　吸着部４・４ａは、偏光フィルムを吸着して固定するための部材である。吸着部４・４ａは、平板形状を有しており、その表面に複数の吸着機構９を備えている。吸着機構９は偏光フィルムを吸着することができれば特に限定されるものではなく、ポンプによって空気を吸引して偏光フィルムを吸着する構成を採用することができる。 The adsorption parts 4 and 4a are members for adsorbing and fixing the polarizing film. The adsorbing parts 4 and 4a have a flat plate shape and are provided with a plurality of adsorbing mechanisms 9 on the surface thereof. The adsorption mechanism 9 is not particularly limited as long as the polarizing film can be adsorbed, and a configuration in which the polarizing film is adsorbed by sucking air with a pump can be adopted.
　切断貼合部５は回転可能であり、複数面を有する。具体的には、切断貼合部５は多角形形状を有している。また、回転可能に配置されている。さらに、好ましい形態として、偏光フィルム１０に対して垂直方向に移動可能となっている。偏光フィルム１０に対して垂直方向に移動可能であることによって、切断貼合部５が回転する際、切断貼合部５は偏光フィルム１０に対して垂直方向であって、偏光フィルム１０から遠ざかる方向に移動でき、その後、回転することができる。その後、切断貼合部５は偏光フィルム１０に対して垂直方向であって、偏光フィルム１０に近接する方向に移動して元の位置に戻ることができる。これにより、切断貼合部５の角部が偏光フィルム１０に接触することを確実に回避することが可能であり、非常に好ましい。 The cutting and bonding unit 5 is rotatable and has a plurality of surfaces. Specifically, the cutting bonding part 5 has a polygonal shape. Moreover, it arrange | positions so that rotation is possible. Furthermore, as a preferable form, it is movable in the vertical direction with respect to the polarizing film 10. By being movable in the vertical direction with respect to the polarizing film 10, when the cutting and bonding unit 5 rotates, the cutting and bonding unit 5 is in a direction perpendicular to the polarizing film 10 and away from the polarizing film 10. Can then be moved and then rotated. Thereafter, the cutting and bonding part 5 is in a direction perpendicular to the polarizing film 10 and can be moved in a direction close to the polarizing film 10 to return to the original position. Thereby, it is possible to avoid reliably that the corner | angular part of the cutting bonding part 5 contacts the polarizing film 10, and it is very preferable.
　なお、切断貼合部５は多角形形状であり、図４にも示すように、その３面に切断支持面５ａ、貼合面５ｂ・５ｃを備えているが、切断支持面および／または貼合面をさらに備えていてもよい。例えば、切断支持面を１面に、貼合面を３面または４面に備えている構成および切断支持面を２面に、貼合面を３面または４面に備えている構成を挙げることができる。なお、図３の切断貼合部５のように、角部は面取りされていれば、偏光フィルムとの接触を回避できる観点から好ましい。切断貼合部５の大きさは、偏光フィルム１０の幅によって適宜決定すればよく、特に限定されるものではないが、例えば、２００ｍｍ以上、２０００ｍｍ以下の長さ、１０ｍｍ以上、３００ｍｍ以下の幅とすることができる。 In addition, although the cutting | disconnection bonding part 5 is polygonal shape and also has the cutting | disconnection support surface 5a and the bonding surfaces 5b * 5c as shown also in FIG. 4, it has a cutting | disconnection support surface and / or bonding. A mating surface may be further provided. For example, a configuration in which the cutting support surface is provided on one surface, a bonding surface is provided on three or four surfaces, and a cutting support surface is provided on two surfaces, and a configuration in which a bonding surface is provided on three or four surfaces are given. Can do. In addition, if the corner | angular part is chamfered like the cutting | lamination bonding part 5 of FIG. 3, it is preferable from a viewpoint which can avoid a contact with a polarizing film. What is necessary is just to determine suitably the magnitude | size of the cutting bonding part 5 with the width | variety of the polarizing film 10, Although it does not specifically limit, For example, the length of 200 mm or more and 2000 mm or less, and the width of 10 mm or more and 300 mm or less can do.
　図４は切断貼合部５を示す斜視図である。図４は、図３の切断貼合部５を時計回りに１／３周回転させた状態を示している。図４に示すように、切断貼合部５は、偏光フィルム１０の幅方向に沿って偏光フィルム１０を支持する切断支持面５ａ、切断された偏光フィルム１０の切断線を覆うように偏光フィルム１０・２０を連結する連結材を吸着する吸着機構９を備える２以上の切断支持面５ａ・貼合面５ｂとを有している。 FIG. 4 is a perspective view showing the cutting and bonding part 5. FIG. 4 shows a state where the cutting and bonding part 5 of FIG. As shown in FIG. 4, the cutting and bonding unit 5 includes the polarizing film 10 so as to cover the cutting support surface 5 a that supports the polarizing film 10 along the width direction of the polarizing film 10 and the cutting line of the cut polarizing film 10. -It has 2 or more cutting support surfaces 5a and the bonding surface 5b provided with the adsorption | suction mechanism 9 which adsorb | sucks the connection material which connects 20. FIG.
　切断支持面５ａには溝状の開口６が形成されており、図３に示す切断貼合部５が備える切断機７の刃の部分が通過できる構造となっている。開口６が形成されていることによって、切断機７の通過を、偏光フィルム１０の幅方向に沿って確実に行うことができ、偏光フィルム１０・２０の連結をより正確に行うことができる。 A groove-shaped opening 6 is formed in the cutting support surface 5a, and the blade portion of the cutting machine 7 provided in the cutting bonding portion 5 shown in FIG. By forming the opening 6, the cutting machine 7 can be reliably passed along the width direction of the polarizing film 10, and the polarizing films 10 and 20 can be more accurately connected.
　切断機７は公知のカッターを採用することができ、偏光フィルム１０を容易に切断できることから、丸刃状であることが好ましい。また、切断機７は偏光フィルム１０の幅方向に駆動可能な台部８によって支持されている。 The cutting machine 7 can employ a known cutter, and can easily cut the polarizing film 10, so that it is preferably a round blade. Further, the cutting machine 7 is supported by a base 8 that can be driven in the width direction of the polarizing film 10.
　貼合面５ｂ・５ｃは互いに同様の構成であり、吸着部４・４ａと同様に複数の吸着機構９を備えている。また、貼合面５ｂ・５ｃには片面粘着テープ（連結材）５ｄが配置されており、片面粘着テープ５ｄの非粘着面が吸着機構９によって保持され、粘着面が貼合面５ｂ・５ｃと反対面となるように配置されている。 The bonding surfaces 5b and 5c have the same configuration, and are provided with a plurality of suction mechanisms 9 in the same manner as the suction portions 4 and 4a. Moreover, the single-sided adhesive tape (connecting material) 5d is arrange | positioned at the bonding surfaces 5b and 5c, the non-adhesive surface of the single-sided adhesive tape 5d is hold | maintained by the adsorption | suction mechanism 9, and an adhesive surface is bonding surfaces 5b and 5c. It is arranged to be on the opposite side.
　上記片面粘着テープ５ｄは偏光フィルム同士を貼合できればよく、公知の片面粘着テープを用いることができる。例えば、テープのフィルム材料としては、ポリエチレンテレフタラートフィルム（ＰＥＴフィルム）、セルロース、和紙、アルミ、不織布、ポリテトラフルオロエチレン、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、ポリウレタン、ＡＢＳ樹脂、ポリエステル、ポリスチレン、ポリエチレン、ポリプロピレン、ポリアセタール樹脂、ポリ乳酸、ポリイミド、ポリアミドなどを挙げることができ、粘着剤層に用いられる粘着剤としては、アクリル系、エポキシ系、ポリウレタン系、合成ゴム系、ＥＶＡ系、シリコーン系、塩化ビニル系、クロロプレンゴム系、シアノアクリレート系、イソシアネート系、ポリビニルアルコール系、メラミン樹脂系などの粘着剤を挙げることができる。 The above single-sided adhesive tape 5d only needs to be able to bond polarizing films together, and a known single-sided adhesive tape can be used. For example, film materials for tape include polyethylene terephthalate film (PET film), cellulose, Japanese paper, aluminum, non-woven fabric, polytetrafluoroethylene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyurethane, ABS resin, polyester, polystyrene, Polyethylene, polypropylene, polyacetal resin, polylactic acid, polyimide, polyamide and the like can be mentioned. As the adhesive used in the adhesive layer, acrylic, epoxy, polyurethane, synthetic rubber, EVA, silicone, Examples of the adhesive include vinyl chloride, chloroprene rubber, cyanoacrylate, isocyanate, polyvinyl alcohol, and melamine resin.
　フィルム連結部３は、偏光フィルム１０に対して対向するように配置される。このため、図１では、偏光フィルム１０が垂直に配置されていることから、フィルム連結部３も偏光フィルム１０に対して垂直に配置されている。一方、偏光フィルム１０が例えば斜め方向（または水平方向など）に配置されている場合、フィルム連結部３も斜め方向（または水平方向など）に配置される構造とすればよい。 The film connecting part 3 is disposed so as to face the polarizing film 10. For this reason, in FIG. 1, since the polarizing film 10 is arrange | positioned perpendicularly | vertically, the film connection part 3 is also arrange | positioned perpendicularly | vertically with respect to the polarizing film 10. FIG. On the other hand, when the polarizing film 10 is arrange | positioned, for example in the diagonal direction (or horizontal direction), what is necessary is just to set it as the structure where the film connection part 3 is also arrange | positioned in the diagonal direction (or horizontal direction).
　フィルム連結部１３はフィルム連結部３と同様の構造である。図１に示すように、フィルム連結部３・１３は、フィルム連結部３・１３に備えられた吸着部４（吸着部４ａ）の吸着機構９同士が対向するように配置されている。また、フィルム連結部３・１３は、偏光フィルム１０および偏光フィルム２０の通過位置を介在させて配置されている。なお、フィルム連結部３・１３を備える製造システム３０は、本実施の形態における好ましい形態であり、フィルム連結部３・１３を備えない形態とすることも可能である。 The film connecting part 13 has the same structure as the film connecting part 3. As shown in FIG. 1, the film connecting portions 3 and 13 are arranged so that the suction mechanisms 9 of the suction portions 4 (the suction portions 4 a) provided in the film connecting portions 3 and 13 face each other. Moreover, the film connection parts 3 and 13 are arranged with the passage positions of the polarizing film 10 and the polarizing film 20 interposed therebetween. In addition, the manufacturing system 30 provided with the film connection part 3 * 13 is a preferable form in this Embodiment, and can also be set as the form which does not include the film connection part 3 * 13.
　〔光学表示装置の製造システムの動作〕
　以下に、本実施の形態に係る製造システム３０の動作について説明する。なお、当該動作に係る説明は、光学表示装置の製造方法の説明を兼ねている。 [Operation of optical display device manufacturing system]
Below, operation | movement of the manufacturing system 30 which concerns on this Embodiment is demonstrated. Note that the description related to the operation also serves as a description of a method of manufacturing the optical display device.
　まず、図１に示すように、巻出部１から偏光フィルム１０を巻き出す（巻出工程）。その後、図２に示すように、図示しないハーフカッターによって偏光フィルム１０のみをハーフカットし、保護フィルム１０ａをナイフエッジ２３によって剥離する（剥離工程）。さらに、液晶パネル２、および、保護フィルム１０ａが剥離された偏光フィルム１０をニップロール２２・２２ａによって圧着することによって貼合する（貼合工程）。なお、剥離された保護フィルム１０ａは図示しない巻取部によって巻き取られ、回収される。上記一連の工程によって、液晶パネル２および偏光フィルム１０とが貼合されて光学表示装置を得ることができる。 First, as shown in FIG. 1, the polarizing film 10 is unwound from the unwinding part 1 (unwinding process). Then, as shown in FIG. 2, only the polarizing film 10 is half-cut by a half cutter (not shown), and the protective film 10a is peeled off by the knife edge 23 (peeling step). Furthermore, the liquid crystal panel 2 and the polarizing film 10 from which the protective film 10a has been peeled off are bonded by pressing with the nip rolls 22 and 22a (bonding step). The peeled protective film 10a is wound and collected by a winding unit (not shown). Through the series of steps, the liquid crystal panel 2 and the polarizing film 10 are bonded to obtain an optical display device.
　上記一連の工程において偏光フィルム１０を巻き出すにつれ、巻出部１に保持された偏光フィルム１０のロールの残量は減少していくこととなる。以下に偏光フィルム同士を連結させる連結工程について説明する。 As the polarizing film 10 is unwound in the series of steps described above, the remaining amount of the roll of the polarizing film 10 held by the unwinding unit 1 decreases. Below, the connection process which connects polarizing films is demonstrated.
　連結工程は、上記第１巻出部の偏光フィルムおよび第２巻出部の偏光フィルムを切断し、巻出部１の偏光フィルム１０および巻出部１１の偏光フィルム２０のうち、巻出部１または巻出部１１のライン側の偏光フィルム１０または２０と、巻出部１１または巻出部１の巻出部側の偏光フィルム２０または１０とを連結する工程である。上記「ライン側」とは、換言すると、偏光フィルムが巻き出される方向を示す。上記連結工程としては、（１）オペレーターによる手法と、（２）フィルム連結部３・１３を用いる手法とを挙げることができる。 A connection process cut | disconnects the polarizing film of the said 1st unwinding part, and the polarizing film of the 2nd unwinding part, The unwinding part 1 among the polarizing film 10 of the unwinding part 1, and the polarizing film 20 of the unwinding part 11 Alternatively, it is a step of connecting the polarizing film 10 or 20 on the line side of the unwinding part 11 and the polarizing film 20 or 10 on the unwinding part side of the unwinding part 11 or unwinding part 1. In other words, the “line side” indicates a direction in which the polarizing film is unwound. Examples of the connecting step include (1) a technique by an operator and (2) a technique using the film connecting portions 3 and 13.
　まず、（１）のオペレーターによる手法について具体的に説明する。オペレーターにより偏光フィルム同士を連結させる場合、偏光フィルム１０の搬送速度を０ｍ／ｍｉｎ．とした後（偏光フィルム１０を停止させた後）に、オペレーターが偏光フィルム１０を切断する。次に、巻出部１１から偏光フィルム２０を巻き出し、端部を切断した後に、例えば、上述した片面粘着テープ５ｄを用いて連結する手法が挙げられる。 First, the method by the operator of (1) will be explained specifically. When the polarizing films are connected by an operator, the conveyance speed of the polarizing film 10 is set to 0 m / min. After the above (after stopping the polarizing film 10), the operator cuts the polarizing film 10. Next, after unwinding the polarizing film 20 from the unwinding part 11 and cutting the end part, for example, a method of connecting using the single-sided adhesive tape 5d described above can be used.
　このように、本発明に係る製造システム３０では、巻出部１・１１の２つの巻出部が備えられており、偏光フィルムのロールを新たなロールに交換せずとも、偏光フィルム１０・２０を用いて即座にフィルムを連結させることができ、速やかに偏光フィルム２０を巻き出すことができる。したがって、従来の巻出部が１箇所にのみ設置された製造システムとは異なり、運転中に空いている方の巻出部において、原反ロールの交換作業が行える為、交換作業に必要な時間を削減することができる。その結果、光学表示装置の製造時間を短縮することが可能である。製造システム３０では、偏光フィルム１０・２０の連結を終えた後、偏光フィルム２０を巻き出す間に、巻出部１の偏光フィルム１０のロールを新たなロールに交換する。偏光フィルム２０の残量が減少した場合、同様に偏光フィルム２０および偏光フィルム１０を連結することももちろん可能である。 Thus, in the manufacturing system 30 according to the present invention, the two unwinding portions of the unwinding portions 1 and 11 are provided, and the polarizing films 10 and 20 can be obtained without replacing the polarizing film roll with a new roll. Can be used to immediately connect the films, and the polarizing film 20 can be unwound quickly. Therefore, unlike the conventional manufacturing system in which the unwinding unit is installed only at one place, the original roll roll can be replaced at the unwinding unit that is vacant during operation. Can be reduced. As a result, it is possible to shorten the manufacturing time of the optical display device. In the manufacturing system 30, after the polarizing films 10 and 20 are connected, the roll of the polarizing film 10 in the unwinding unit 1 is replaced with a new roll while the polarizing film 20 is unwound. When the remaining amount of the polarizing film 20 decreases, it is of course possible to connect the polarizing film 20 and the polarizing film 10 in the same manner.
　次に、フィルム連結部３・１３を用いる場合について図５を用いて具体的に説明する。図５は、製造システム３０による連結工程を示す工程図である。偏光フィルム１０の残量が減少すると、偏光フィルム１０の図５（ａ）に示すように、偏光フィルム１０の搬送速度を０ｍ／ｍｉｎ．とした後に、吸着部４・４ａおよび切断貼合部５（フィルム連結部３）を偏光フィルム１０に対して垂直方向に移動させる。次に、吸着部４・４ａの吸着機構９によって、偏光フィルム１０を吸着して固定する（吸着工程）。 Next, the case where the film connecting portions 3 and 13 are used will be specifically described with reference to FIG. FIG. 5 is a process diagram showing a connecting process by the manufacturing system 30. When the remaining amount of the polarizing film 10 decreases, as shown in FIG. 5A of the polarizing film 10, the conveying speed of the polarizing film 10 is set to 0 m / min. Then, the adsorbing parts 4 and 4a and the cutting and bonding part 5 (film connecting part 3) are moved in the vertical direction with respect to the polarizing film 10. Next, the polarizing film 10 is sucked and fixed by the suction mechanism 9 of the suction parts 4 and 4a (suction process).
　この際、切断貼合部５では、切断支持面５ａが偏光フィルム１０に接触している。その後、図５（ｂ）に示すように、図示しない切断機を開口６に沿って移動させて偏光フィルム１０を切断する（切断工程）。切断後、切断貼合部５を偏光フィルム１０に対して垂直方向であって、偏光フィルム１０から遠ざかる方向（図中左側）に移動し、時計回りに１／３周回転させ、偏光フィルム１０に対して垂直方向であって、偏光フィルム１０から接近する方向（図中右側）に移動させる。これにより、図５（ｃ）に示すように、片面粘着テープ５ｄ（図示せず）と対向する偏光フィルム１０の切断線を覆うように、貼合面５ｂの片面粘着テープ５ｄを貼り合わせる（貼合工程）。上記切断線とは、切断工程によって、偏光フィルム１０に生じた切断面のうち、貼合面５ｂと対向する辺を示す。貼合工程では、片面粘着テープ５ｄは上記切断線を覆うように配置される、すなわち、偏光フィルム１０が上記切断線を越えて、偏光フィルム１０が存在しない部分についても配置される。 At this time, the cutting support surface 5 a is in contact with the polarizing film 10 in the cutting and bonding unit 5. Then, as shown in FIG.5 (b), the cutting machine which is not shown in figure is moved along the opening 6, and the polarizing film 10 is cut | disconnected (cutting process). After cutting, the cutting and bonding part 5 is moved in the direction perpendicular to the polarizing film 10 and away from the polarizing film 10 (left side in the figure), and rotated clockwise by 1/3 turn to the polarizing film 10. On the other hand, it is moved in a direction perpendicular to the polarizing film 10 (right side in the figure). Thereby, as shown in FIG.5 (c), the single-sided adhesive tape 5d of the bonding surface 5b is bonded together so that the cutting line of the polarizing film 10 facing the single-sided adhesive tape 5d (not shown) may be covered (pasting). Joint process). The said cutting line shows the edge | side which opposes the bonding surface 5b among the cut surfaces produced in the polarizing film 10 by the cutting process. In the bonding step, the single-sided adhesive tape 5d is disposed so as to cover the cutting line, that is, the polarizing film 10 is also disposed on a portion where the polarizing film 10 does not exist beyond the cutting line.
　さらに、偏光フィルム２０に対しても、図５（ｄ）～（ｅ）と同様にして、偏光フィルム２０の切断支持面１５ａに片面粘着テープ１５ｄを粘着する。上述した部材と同様の部材には同一の名称を付し、その説明を省略する。 Furthermore, the single-sided adhesive tape 15d is adhered to the cut support surface 15a of the polarizing film 20 in the same manner as in FIGS. The same members as those described above are given the same names, and the description thereof is omitted.
　まず、偏光フィルム２０を巻出部１１から巻き出して、図５（ａ）と同様に、偏光フィルム２０の端部を切断した後、図示しない切断機を、切断支持面１５ａに形成された開口に沿って移動させて偏光フィルム２０を切断する。切断後、切断貼合部１５を偏光フィルム２０に対して垂直方向であって、偏光フィルム２０から遠ざかる方向（図中右側）に移動し、反時計回りに１／３周回転させ、偏光フィルム２０に対して垂直方向であって、偏光フィルム２０から近接する方向（図中左側）に移動させる。これにより、図５（ｅ）に示すように、貼合面１５ｂの片面粘着テープ１５ｄと対向する偏光フィルム２０の切断線を覆うように、片面粘着テープ１５ｄを貼り付けることができる。 First, after the polarizing film 20 is unwound from the unwinding portion 11 and the end portion of the polarizing film 20 is cut in the same manner as in FIG. 5A, a cutting machine (not shown) is formed in the opening formed on the cutting support surface 15a. And the polarizing film 20 is cut. After cutting, the cutting and bonding unit 15 is moved in the direction perpendicular to the polarizing film 20 and away from the polarizing film 20 (right side in the figure), and rotated counterclockwise by 1/3 turn, the polarizing film 20 In the direction perpendicular to the polarizing film 20 (left side in the figure). Thereby, as shown in FIG.5 (e), the single-sided adhesive tape 15d can be affixed so that the cutting line of the polarizing film 20 facing the single-sided adhesive tape 15d of the bonding surface 15b may be covered.
　次に、図５（ｆ）に示すように、吸着部４・４ａおよび切断貼合部５（フィルム連結装置３）を吸着部１４・１４ａおよび切断貼合部１５（フィルム連結部１３）に近接させ、偏光フィルム１０および偏光フィルム２０の切断面同士を合わせる（近接工程）。これにより、偏光フィルム１０・２０の切断線を覆う片面粘着テープ５ｄ・１５ｄのうち、切断線を越えた部分（偏光フィルム１０・２０に貼合していない部分）が、他方の偏光フィルム２０・１０に貼合することによって、偏光フィルム１０・２０が連結される。図５（ｆ）では、フィルム連結部３をフィルム連結部１３へ近接させたが、フィルム連結部１３をフィルム連結部３へ近接させてもよく、また、フィルム連結部３・１３を互いに近接させてもよい。 Next, as shown in FIG.5 (f), adsorption | suction part 4 * 4a and the cutting | disconnection bonding part 5 (film connection apparatus 3) adjoin to adsorption | suction part 14 * 14a and the cutting | disconnection bonding part 15 (film connection part 13). The cut surfaces of the polarizing film 10 and the polarizing film 20 are matched with each other (proximity step). Thereby, among the single-sided adhesive tapes 5d and 15d covering the cutting lines of the polarizing films 10 and 20, the part beyond the cutting line (the part not bonded to the polarizing films 10 and 20) is the other polarizing film 20 The polarizing films 10 and 20 are connected to each other. In FIG. 5 (f), the film connecting part 3 is brought close to the film connecting part 13, but the film connecting part 13 may be made close to the film connecting part 3, and the film connecting parts 3 and 13 are made close to each other. May be.
　偏光フィルム１０・２０を連結させた後には、準備工程として、図５（ｇ）に示すように、切断貼合部５・１５をそれぞれ偏光フィルム１０・２０に対して垂直方向であって、遠ざかる方向へ移動させ、切断貼合部５を反時計回りに１／３周回転させ、切断貼合部１５を時計回りに１／３周回転させる。そして、切断貼合部５・１５をそれぞれ偏光フィルム１０・２０に対して垂直方向であって、近接する方向へ移動させる。 After connecting the polarizing films 10 and 20, as a preparation step, as shown in FIG. 5 (g), the cutting and bonding parts 5 and 15 are perpendicular to the polarizing films 10 and 20, respectively, and are moved away. It moves to a direction, the cutting bonding part 5 is rotated 1/3 times counterclockwise, and the cutting bonding part 15 is rotated 1/3 times clockwise. And the cutting bonding parts 5 and 15 are perpendicular | vertical with respect to the polarizing films 10 and 20, respectively, and are moved to the direction which adjoins.
　最後に、吸着部４・４ａおよび切断貼合部５（フィルム連結部３）を図５（ａ）の位置に戻し、一連の工程が終了する。なお、貼合面５ｃ・１５ｃには、片面粘着テープ５ｄ・１５ｄが予め吸着された状態にて備えられているため、巻出部１に新たな偏光フィルム１０のロールが設置された後に、偏光フィルム２０に対して図５（ａ）～（ｃ）の工程、偏光フィルム１０に対して図５（ｄ）～（ｅ）の工程を行い、上述したように図５（ｆ）～（ｈ）の工程を経て、偏光フィルム２０・１０を連結させることができる。また、使用した片面粘着テープ５ｄ・１５ｄを補充することによって、連続して偏光フィルムを連結することももちろん可能である。 Finally, the adsorbing parts 4 and 4a and the cutting and bonding part 5 (film connecting part 3) are returned to the positions shown in FIG. 5 (a), and the series of steps is completed. In addition, since the single-sided adhesive tapes 5d and 15d are preliminarily adsorbed on the bonding surfaces 5c and 15c, after the roll of the new polarizing film 10 is installed on the unwinding unit 1, the polarized light is applied. 5 (a)-(c) is performed on the film 20, and the steps of FIGS. 5 (d)-(e) are performed on the polarizing film 10. As described above, the steps of FIGS. 5 (f)-(h) are performed. Through the process, the polarizing films 20 and 10 can be connected. In addition, it is of course possible to continuously connect the polarizing films by replenishing the used single-sided adhesive tapes 5d and 15d.
　上述のように、フィルム連結部３・１３を用いた連結工程の場合、オペレーターによる連結工程と比較して、偏光フィルムの吸着、切断、貼合をより短時間に、また、より正確に行うことが可能となるため好ましい。 As described above, in the case of the connecting step using the film connecting portions 3 and 13, the polarizing film is adsorbed, cut, and bonded in a shorter time and more accurately than the connecting step by the operator. Is preferable.
　具体的には、製造システム３０において、オペレーターによる連結工程の場合、１０分程度必要であったが、フィルム連結部３・１３を用いた場合、１分以下とすることができた。 Specifically, in the manufacturing system 30, in the case of the connecting step by the operator, about 10 minutes were required, but when the film connecting portions 3 and 13 were used, the time could be reduced to 1 minute or less.
　なお、製造システム３０において、巻出部１のみを使用し、巻出部１１を使用せず、さらにフィルム連結部３・１３も使用しない場合、オペレーターは巻出部１に新たな偏光フィルムを交換した後に偏光フィルム１０を交換する必要があることから、連結工程には３０分程度必要である。このため、本実施の形態に係る製造システム３０が有益であることは明らかである。 In the manufacturing system 30, when only the unwinding unit 1 is used, the unwinding unit 11 is not used, and the film connecting units 3 and 13 are not used, the operator replaces a new polarizing film with the unwinding unit 1. After that, the polarizing film 10 needs to be replaced, so that the connecting step requires about 30 minutes. For this reason, it is clear that the manufacturing system 30 according to the present embodiment is useful.
　なお、本発明は、上述した各実施形態に限定されるものではなく、請求項に示した範囲で種々の変更が可能であり、異なる実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本発明の技術的範囲に含まれる。例えば、製造システムにおけるガイドロールの本数や、巻出部、巻取部、フィルム連結部および搬送機構の配置などは図示された配置に限定されるものではない。 The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention. For example, the number of guide rolls in the manufacturing system and the arrangement of the unwinding unit, the winding unit, the film connecting unit, and the transport mechanism are not limited to the illustrated arrangement.
　また、本発明には以下の態様も含まれる。 The present invention also includes the following aspects.
　本発明の光学表示装置の製造システムでは、第１巻出部から巻出された偏光フィルムおよび第２巻出部から巻出された偏光フィルムを連結させる、第１フィルム連結部および第２フィルム連結部が、上記の両偏光フィルムの通過位置を介在し、かつ、第１フィルム連結部は第１巻出部から巻出された偏光フィルムに対向して配置され、第２フィルム連結部は第２巻出部から巻出された偏光フィルムに対向して配置されており、上記第１フィルム連結部および第２フィルム連結部は、偏光フィルムを吸着可能な吸着機構を備える２つの吸着部と、上記２つの吸着部の間であり、かつ、偏光フィルムの幅方向に沿って回転可能に配置された、切断貼合部とを備えており、上記切断貼合部は、偏光フィルムを切断する切断機を備えていると共に、切断貼合部が有する複数面は、偏光フィルムの幅方向に沿って偏光フィルムを支持する切断支持面と、上記偏光フィルム同士を連結する連結材を吸着して保持する吸着機構を備えた、２以上の貼合面とを少なくとも有しており、上記第１フィルム連結部および第２フィルム連結部は、互いに近接可能であることが好ましい。 In the optical display device manufacturing system of the present invention, the first film connecting portion and the second film connecting portion that connect the polarizing film unwound from the first unwinding portion and the polarizing film unrolled from the second unwinding portion. The first film connecting portion is disposed opposite to the polarizing film unwound from the first unwinding portion, and the second film connecting portion is the second. It arrange | positions facing the polarizing film unwound from the unwinding part, The said 1st film connection part and the 2nd film connection part are two adsorption parts provided with the adsorption | suction mechanism which can adsorb | suck a polarizing film, and the said A cutting and bonding unit disposed between the two adsorbing units and rotatably disposed along the width direction of the polarizing film, and the cutting and bonding unit cuts the polarizing film. With The plurality of surfaces of the cut-and-paste part includes a cutting support surface that supports the polarizing film along the width direction of the polarizing film, and an adsorption mechanism that adsorbs and holds the connecting material that connects the polarizing films to each other. It has at least the above bonding surface, and it is preferable that the first film connecting portion and the second film connecting portion can be close to each other.
　これにより、上記吸着部によって偏光フィルムを吸着し、吸着した偏光フィルムを切断支持面にて支持した状態にて切断機によって切断することができる。その後、切断貼合部を回転させて、切断した偏光フィルムに対して、貼合面の連結材を貼合することができる。さらに、第１フィルム連結部および第２フィルム連結部を互いに近接させ、連結材が貼合された２枚の偏光フィルムを接触させて容易に連結することができる。 Thereby, the polarizing film can be adsorbed by the adsorbing portion, and the adsorbing polarizing film can be cut by the cutting machine while being supported by the cutting support surface. Then, the cutting bonding part can be rotated and the connection material of a bonding surface can be bonded with respect to the cut | disconnected polarizing film. Furthermore, the 1st film connection part and the 2nd film connection part can mutually be brought close, and the two polarizing films with which the connection material was bonded can be contacted and can be connected easily.
　また、本発明の光学表示装置の製造システムでは、上記切断支持面には、上記偏光フィルムの幅方向に沿って上記切断機が通過可能な開口が形成されていることが好ましい。 In the optical display device manufacturing system of the present invention, it is preferable that an opening through which the cutting machine can pass is formed in the cutting support surface along the width direction of the polarizing film.
　これにより、切断機の通過を、偏光フィルムの幅方向に沿って確実に行うことができ、後に偏光フィルム同士の連結をより正確に行うことができる。 Thereby, the cutting machine can be reliably passed along the width direction of the polarizing film, and the polarizing films can be more accurately connected later.

　これにより、切断貼合部が回転する際、切断貼合部は偏光フィルムに対して垂直方向であって、偏光フィルムから遠ざかる方向に移動でき、その後、回転することができる。これにより、切断貼合部が回転する際、偏光フィルムに接触することを確実に回避することができる。 Thereby, when the cutting and bonding part rotates, the cutting and bonding part can be moved in a direction perpendicular to the polarizing film and away from the polarizing film, and then rotated. Thereby, when a cutting bonding part rotates, it can avoid reliably contacting a polarizing film.

A polarizing film can be unwound. Therefore, since the time required for the replacement work of the roll of the unwinding part can be reduced, it is possible to provide a manufacturing method for shortening the manufacturing time of the optical display device.
