DISCLOSURE OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method for transporting an adhesive layer, a long strip-shaped heavy release film, and a peeling force smaller than the heavy release film to be peeled off from the adhesive layer And a long strip-shaped thin film laminated body formed by laminating the heavy release film, the adhesive layer, and the light release film in this order, and the light release film is continuously continuous from the film laminate Stripping method and peeling device. [Prior Art] Nowadays, a liquid crystal display device in which a polarizing plate is bonded to both sides of a liquid crystal panel is generally manufactured. After the module is manufactured, the liquid crystal display device undergoes various assembly steps, and then becomes a mobile device such as a notebook personal computer or a mobile phone, or even a large-sized television or the like (final product). The polarizing plate is wound up by a long-length polarizing plate which is wound into a reel shape, and cut into a predetermined length, and then used for bonding to a single-piece liquid crystal panel. The polarizing plate original plate is formed by, for example, laminating an adhesive layer, a polarizing film, an adhesive layer, and a protective film in this order on the release film. One of the pressure-sensitive adhesive layers is formed by bonding a release film to a polarizing film and bonding a polarizing film to a liquid crystal panel. In the above adhesive layer, the other adhesive layer is formed by bonding a protective film to a polarizing film. In general, the above-mentioned adhesive layer in the polarizing plate is formed by bonding an adhesive layer laminated on the release film (and the protective film) to the polarizing film in the shape of 4,322,923, 201200944. Specifically, it is composed of an adhesive layer, a long strip-shaped heavy release film, and a long strip-shaped peeling film which can be peeled off from the above-mentioned adhesive layer by a peeling force smaller than the heavy release film, and The peeling film (that is, the film forming the release film or the protective film), the adhesive layer, and the light release film are laminated in this order, and the long film-like laminate is peeled off from the light release film, and then the adhesive layer is attached to the polarizing film. The above-mentioned adhesive layer in the polarizing plate is formed. Further, the above-mentioned thin film laminate is sometimes referred to as a non-carrier film (so-called double-sided tape). Further, various peeling apparatuses for peeling the light release film from the film laminate have been proposed. For example, Patent Document 1 describes a separator peeling device for preventing a change in the tensile force (tension) of the substrate when the separator (light release film) is peeled off from the substrate (film laminate). Further, Patent Document 2 describes a second sheet (heavy release film and adhesion) in which the first sheet (light release film) can be smoothly peeled off from the sheet (film laminate) and dust or the like is prevented from adhering to the peeled film. Transfer layer peeling device. (Prior Art Document) (Patent Document 1) Japanese Laid-Open Patent Publication No. 2002-201439 (published Jul. 19, 2002) (Patent Document 2) 曰 National Patent Publication No. 11-208985 [Explanation] (Problem to be solved by the invention) 5 322923 201200944 The separator peeling device described in Patent Document 1 is as described in the drawings, and only the separator is applied. The tension is peeled off, that is, the tension is controlled, and on the other hand, the substrate after the release film is peeled off is subjected to speed control (winding control). Further, the transfer peeling device described in the above Patent Document 2 is as paragraph [ In the case of the sheet, the first sheet, and the second sheet, the peeling is applied to the sheet, the first sheet, and the second sheet, but the tension applied to the three sheets is not specifically described. The transfer-and-peel device described in Patent Document 2 simply peels the sheet, the second sheet, and the second sheet by applying tension. "The stripping film is peeled off from the film laminate, and the adhesive layer must be avoided. Residual in light peeling thin However, the above-mentioned conventional peeling apparatus does not particularly consider what kind of tension is applied to the film (sheet) corresponding to the heavy release film and the light release film, and therefore, conventional peeling is performed. In the case of the film, the peeling method of the film (sheet) is unstable, and there is a problem that the adhesive layer (transfer layer) of the adhesive layer may remain on the film (sheet) side. - The peeling method of the lightly peeling film becomes unstable, which causes the phenomenon that the adhesive layer is opened on the side of the heavy release film and the side of the light release film (the layer is sticky (four) j layer cannot be completely removed from the light lining film Off, so that tearing 4 or drawing) ° especially when the width direction of the film laminate to be peeled off 2 the blade section 'has a slight unevenness (so-called burr) on the end face, so 4 is easy to cause the above I even The adhesive layer that causes the above phenomenon is bonded to the polarizing film, and it is impossible to produce a polarizing plate of good quality. The main purpose of the present invention is to provide a light peeling effect in view of the above-mentioned problems. The film is continuously and stably peeled off from the film laminate to prevent the adhesive layer from remaining on the side of the light release film and the peeling device. i (Means for Solving the Problem) In order to solve the above problems, the peeling method of the present invention is carried by An adhesive layer, a long strip-shaped heavy release film, and a long strip-shaped peeling film which can be peeled off from the adhesive layer by a peeling force smaller than the heavy release film, and is a heavy release film, an adhesive layer, and A strip-shaped film laminate which is laminated in this order, and a peeling method for continuously peeling the light-peelable film from the film-layered body by a peeling roller, wherein the tension and weight of the light-peeling film to be conveyed are controlled The tension of the release film is fixed to each other, and the conveyance direction of the heavy release film is changed along the peeling roller with respect to the conveyance direction of the light release film. According to the above configuration, the tension of the light release film conveyed by the control (tension control) and the tension of the heavy release film are fixed to each other, that is, the tension of the light release film to be conveyed and the tension of the heavy release film are fixed, respectively. It does not change, so that the light release film and the heavy release film are less likely to wrinkle, and there is no fear that the peeling position will move from the peeling roller (the peeling position can be stabilized). Therefore, the light release film can be stably peeled off so that the adhesive layer does not remain on the side of the light release film. Thereby, it is possible to provide a peeling method in which the light release film is continuously and stably peeled off from the film laminate to prevent the adhesive layer from remaining on the side of the light release film. Moreover, it is preferable that the peeling method of the present invention changes the direction in which the light release film is transported along the peeling roller. Preferably, the stripping method of the present invention controls the tension of the light release film and the tension of the heavy release film which are carried by the 7322923 201200944 to 50 N or more. Preferably, the stripping method of the present invention is such that the tension of the transported heavy release film is greater or equal to the tension of the light release film. Preferably, the stripping method of the present invention is such that the direction of conveyance of the heavy release film is 35 with respect to the direction of transport of the light release sheet. Above, 18〇. the following. According to these methods, the light release film can be continuously and more stably peeled off from the film laminate to prevent the adhesive layer from remaining on the light release thin side. Further, in the peeling method of the present invention, the width direction of the film laminate may be a cut surface. According to the above configuration, since the light-removable thin enamel can be continuously and stably peeled off, even if the end surface in the width direction of the thin-film layered body to be peeled off is a cut surface, that is, even if there is minute unevenness (so-called burr) on the end surface, The adhesive layer also does not remain on the side of the light release film. Further, in the peeling method of the present invention, it is preferable that the film laminate has a width of 200 mm or more. In order to solve the above problems, the peeling device of the present invention transports an adhesive layer, a long strip-shaped heavy release film, and a strip-shaped light which can be peeled off from the adhesive layer by a small peeling force smaller than the heavy peeling film. A strip-shaped film laminate which is formed by laminating a thin film, an adhesive layer, and a light release film in this order, and a peeling device for continuously peeling the light release film from the film laminate a peeling roller that changes a conveyance direction of the heavy release film with respect to a conveyance direction of the light release film; a control unit that controls the tension of the light release film to be conveyed and the tension of the heavy release film to be fixed; and A measuring unit that gently peels the tension of the film and the tension of the heavy peeling film.
S 322923 201200944 根據上述構造，由於是藉由控制部來控制（張力控制） 所搬運的輕剝離薄膜之張力及重剝離薄膜之張力使其各自 固定，亦即，所搬運的輕剝離薄膜之張力及重剝離薄膜之 張力是各自固定，並不會改變，因此在輕剝離薄膜及重剝 離薄膜不容易產生皺折，而且不用擔心剝離位置會從剝離 滚輪移動（可使剝離位置穩定）。因此，可使輕剝離薄膜穩 定地剝離，以免黏著劑層殘留在輕剝離薄膜侧。藉此，可

述構造，即使重剝離薄膜之搬運方向相對於輕剝離薄膜之 搬運方向的角度改變，也可藉由固定引導滾輪使搬運滾輪 9 322923 201200944 的輕剝離薄膜及重剝離薄膜的繞角固定。亦即，可使利用 測定部的輕剝離薄膜之張力及重剝離薄膜之張力的測定條 件恆常保持一定，因此可更穩定地利用控制部來進行張力 控制。藉此，可提供一種可使輕剝離薄膜從薄膜積層體連 續且更穩定地剝離的剝離裝置。 (發明之效果） 根據本發明之剝離方法及剝離裝置，由於所搬運的輕 剝離薄膜之張力及重剝離薄膜之張力是各自固定，並不會 改變，因此可使輕剝離薄膜穩定地剝離，以免黏著劑層殘 留在餐剝離薄膜側。藉此，會達成可提供一種可使輕剝離 薄膜從薄膜積層體連續且穩定地剝離，以免黏著劑層殘留 在輕剝離薄膜側的剝離方法及剝離裝置的效果。 本發明之其他目的、特徵及優點應可由以下的記載充 分明白。又，本發明之優點應該由參照所附圖式的以下說

針對本發明之一實施形態’若根據第1圖來加以說明， 則如以下所述。 首先’針對藉由本發明之剝離裝置進行剝離的薄膜積 層體之一例加以說明。上述薄膜積層體是由黏著劑層、長 條狀重剝離薄膜、以及可利用比該重剝離薄膜小的剝離力 從上述黏著劑層剝離的長條狀輕剝離薄膜所構成，並且為 將上述重剝離薄膜、黏著劑層及輕制離薄膜以此順序積層 而成的長條狀薄膜積層體。此外，上述薄膜積層體有時也 被稱為無載體薄膜（所謂的雙面膠帶）。 11 322923 201200944 紅構成上述黏㈣層的黏著劑例如可為丙烯酸樹脂或聚-氛酉曰祕月曰等以聚合物為主要成分的眾所周知的黏著劑。尤. 八在要求透明性的情況，以丙缚酸樹脂為主要成分的眾所. 周知^黏著劑更佳。上述眾所周知的黏著劑是也被稱為感 壓接著劑的黏彈性體’具備只要按壓就會接著在黏附物的 表面（黏附面），另一方面要從黏附物撕開時，可避免黏著 劑殘留β在表面（黏附面）側（實際上不會留下痕跡）地撕開 (然而是在黏附物有耐得起撕開之強度的情況）的性質。上 述黏著劑層可藉由將例如使上述黏著劑溶解於溶劑令所形 成的浴液，塗布在上述重剝離薄膜或輕剝離薄膜並使其乾 燥而形成。上述黏著劑層的厚度並沒有特別的限定，但是 大概在5 " m以上。 上述重剝離薄膜在例如將黏著劑層貼合在偏光薄膜的 情況，也就是將黏著劑層貼合在偏光薄臈所製造出的偏光 板中，是會形成剝離薄膜（或保護薄膜）的薄膜。重剝離薄 膜是由透明的樹脂薄膜，例如聚對苯二甲酸乙二酯、聚萘 二甲酸乙二酯、聚對苯二甲酸丁二酯等聚酯樹脂薄膜等所 構成。 上述輕剝離薄膜是由在其表面進行過眾所周知之脫模 處理的透明樹脂薄膜所構成。因此，輕剝離薄膜可利用比 重剥離薄膜小的剝離力從黏著劑層剝離，而且是將進行過 脫模處理的面貼合在黏著劑層。輕剝離薄膜是由透明的樹 脂薄膜，例如聚對苯二甲酸乙二酯、聚萘二甲酸乙二酯、 聚對苯二甲酸丁二酯等聚酯樹脂薄膜等所構成。 322923 12 201200944 上述薄膜積層體通常是做成寬幅的薄膜積層體原板之 後，將該薄膜積層體原板切斷成預定之寬度而作成。因此， 薄膜積層體的寬度方向端面通常是形成切斷面。又，上述 薄膜積層體的寬度並沒有特別的限定，但是大概為200mm 以上。此外，長條狀薄膜積層體由於重剝離薄膜與輕剝離 薄膜的剝離力不同，因此大致是以重剝離薄膜形成内側的 方式捲繞。 針對本發明之剝離裝置的構造之一例加以說明。如第 1圖所示，本實施形態之剝離裝置20是用來搬運長條狀薄 膜積層體30,同時使輕剝離薄膜31從該薄膜積層體30連 續剝離的剝離裝置。剝離裝置20主要是由以下構件構成： 分別由一對夾持滾輪形成的第一夾持部1、第二夾持部2 及第三夾持部3、剝離滾輪4、引導滾輪5、6、7及搬運滾

薄膜31之張力及重剝離薄膜32之張力分別是固定的，不 會改變，因此在輕剝離薄膜31及重剝離薄膜32不容易產 生皺折，而且不用擔心剝離位置會從剝離滾輪4移動（可使 剝離位置穩定）。因此，可使輕剝離薄膜31穩定地剝離， 以免黏著劑層殘留在輕剝離薄膜31側。藉此，可提供一種 可使輕剝離薄膜31從薄膜積層體30連續且穩定地剝離， 以免黏著劑層殘留在輕剝離薄膜31侧的剝離裝置。

by the control unit (tension control) and the tension of the heavy release film are fixed to each other, that is, the tension of the light release film to be conveyed and The tension of the heavy release film is fixed and does not change, so that the light release film and the heavy release film are less likely to wrinkle, and there is no fear that the peeling position will move from the peeling roller (the peeling position can be stabilized). Therefore, the light release film can be stably peeled off so that the adhesive layer remains on the side of the light release film. Thereby, it is possible to provide a peeling device which can continuously and stably peel the light release film from the film laminate to prevent the adhesive layer from remaining on the side of the light release film. Further, it is preferable that the peeling device of the present invention is provided with a variable guide roller which arbitrarily changes the conveyance direction of the heavy release film with respect to the conveyance direction of the light release film. According to the above configuration, depending on the type of the film laminate, that is, the material of the light release film, the adhesive layer, and the heavy release film, the material, the nature, the thickness, and the like, the film can be peeled off from the direction of the light release film. The angle of the conveying direction changes. Thereby, it is possible to provide a peeling device which can continuously and more stably peel the light release film from the film laminate. Further, the peeling device of the present invention preferably further includes a transport roller for transporting the peeled light release film and the heavy release film, and the measuring portion is provided on the transport roller, and the variable guide roller and the transport roller are A fixed guide roller for adjusting the conveyance direction of the light release film and the heavy release film is provided to fix the corner of the conveyance roller. According to the above configuration, even if the angle of conveyance of the heavy release film with respect to the conveyance direction of the light release film is changed, the angles of the light release film and the heavy release film of the conveyance roller 9 322923 201200944 can be fixed by fixing the guide roller. In other words, the measurement conditions of the tension of the light release film and the tension of the heavy release film by the measurement unit can be kept constant, so that the control unit can be used more stably for tension control. Thereby, it is possible to provide a peeling device which allows the light release film to be continuously and more stably peeled off from the film laminate. (Effect of the Invention) According to the peeling method and the peeling device of the present invention, since the tension of the lightly peeling film to be conveyed and the tension of the heavy peeling film are fixed and are not changed, the lightly peeling film can be stably peeled off, thereby avoiding The adhesive layer remains on the side of the meal peeling film. As a result, it is possible to provide a peeling method and a peeling device which can continuously and stably peel the light release film from the film laminate to prevent the adhesive layer from remaining on the side of the light release film. Other objects, features and advantages of the present invention will be apparent from the description. Further, the advantages of the present invention should be understood from the following description with reference to the accompanying drawings. [Embodiment] The peeling device of the present invention is for transporting a long strip-shaped peeling film which is peeled off from the above-mentioned adhesive layer by an adhesive layer, a long strip-shaped heavy release film, and a peeling force smaller than the heavy peeling film. And a strip-shaped thin layered body in which the above-mentioned heavy release film, adhesive layer, and light release film are laminated in this order, and a peeling device in which the light release film is continuously peeled off from the film laminate; a peeling roller that changes a conveyance direction of the heavy release film with respect to a conveyance direction of the light release film; and a control unit that controls the tension of the peeled film and the tension of the heavy release film to be fixed to each other; 322923 10 201200944 '; A measuring unit for measuring the tension of the light release film and the tension of the heavy release film. Further, the peeling method of the present invention is for transporting a long strip-shaped peeling film which is peeled off from the above-mentioned adhesive layer by an adhesive layer, a long strip-shaped heavy peeling film, and a peeling force smaller than the heavy peeling film. A strip-shaped film laminate in which the heavy release film, the adhesive layer, and the light release film are laminated in this order, and a peeling method in which the light release film is continuously peeled off from the film laminate by a peeling roller It is configured to control the conveyance direction of the heavy release film with respect to the conveyance direction of the light release film along the peeling roller while controlling the tension of the light release film to be conveyed and the tension of the heavy release film to be fixed. Further, the term "tension" as used in the present invention means a stress applied per unit time per unit area of a film laminate, a light release film or a heavy release film. [Embodiment 1] An embodiment of the present invention will be described below with reference to Fig. 1 . First, an example of a film laminate which is peeled off by the peeling device of the present invention will be described. The film laminate is composed of an adhesive layer, a long heavy release film, and a long strip-shaped peeling film which can be peeled off from the adhesive layer by a peeling force smaller than the heavy release film, and the weight is A strip-shaped film laminate in which a release film, an adhesive layer, and a light release film are laminated in this order. Further, the above-mentioned film laminate is sometimes referred to as an unsupported film (so-called double-sided tape). 11 322923 201200944 Red The adhesive constituting the above-mentioned adhesive layer may be, for example, a well-known adhesive containing a polymer as a main component such as an acrylic resin or a polystyrene. In particular, in the case of requiring transparency, the company is mainly composed of acrylic acid resin. It is better to know that the adhesive is better. The above-mentioned well-known adhesive is a viscoelastic body which is also called a pressure-sensitive adhesive. It has a surface which is adhered to the surface of the adhesive (adhesion surface) as long as it is pressed, and on the other hand, when the tear is torn off from the adhesive, the adhesive can be avoided. The residual β is torn on the side of the surface (adhesion side) (actually leaving no trace) (however, in the case where the adhesive has the strength to withstand tearing). The above-mentioned adhesive layer can be formed by applying, for example, a bath formed by dissolving the above-mentioned adhesive in a solvent to the above-mentioned heavy release film or light release film and drying it. The thickness of the above adhesive layer is not particularly limited, but is approximately 5 " m or more. The above-mentioned heavy release film is, for example, a film in which a pressure-sensitive adhesive layer is bonded to a polarizing film, that is, a pressure-sensitive adhesive layer is bonded to a polarizing plate manufactured by a polarizing film, and a film which forms a release film (or a protective film) is formed. . The heavy release film is composed of a transparent resin film such as a polyester resin film such as polyethylene terephthalate, polyethylene naphthalate or polybutylene terephthalate. The above light release film is composed of a transparent resin film which has been subjected to a well-known release treatment on its surface. Therefore, the light release film can be peeled off from the adhesive layer by a small peeling force of the specific weight release film, and the surface subjected to the release treatment can be bonded to the adhesive layer. The light release film is composed of a transparent resin film such as a polyester resin film such as polyethylene terephthalate, polyethylene naphthalate or polybutylene terephthalate. 322923 12 201200944 The above-mentioned film laminate is usually formed by forming a wide film laminate original sheet, and then cutting the original film laminate body into a predetermined width. Therefore, the end surface in the width direction of the film laminate usually forms a cut surface. Further, the width of the film laminate is not particularly limited, but is approximately 200 mm or more. Further, since the long film-shaped laminate has a different peeling force from the light release film and the light release film, it is roughly wound so that the heavy release film is formed inside. An example of the structure of the peeling device of the present invention will be described. As shown in Fig. 1, the peeling device 20 of the present embodiment is a peeling device for transporting the long film-form laminate 30 and continuously peeling the light release film 31 from the film laminate 30. The peeling device 20 is mainly composed of the following members: a first holding portion 1, a second holding portion 2 and a third holding portion 3, a peeling roller 4, and guiding rollers 5, 6, respectively formed by a pair of holding rollers. 7 and carrying rollers 8, 9 Further, each of these rollers is a frame (not shown) fixed to the peeling device 20. The first holding portion 1 has a function of continuously ejecting the long film laminated body 30 wound from the unwinding portion (not shown) toward the peeling roller 4 side. The pair of holding rollers forming the first holding portion 1 are provided such that their axial cores (central axes) are parallel to each other, and are formed of a soft material such as rubber. The pinch roller can be specifically a well-known pinch roller. Further, the holding roller of at least one of the pair of holding rollers is a driving roller, and the rotation speed thereof can be arbitrarily adjusted, and is arranged to be movable up and down, so that the pressure of the first clamping portion 1 can be appropriately adjusted as needed (nip pressure) ). The second holding portion 2 has a long strip light 13 322923 201200944 film 31 which is peeled off from the film laminate 30, and is wound around a winding portion (not shown)*. The pair of holding rollers of the one-to-one holding portion 2 are disposed such that their axial cores (central axes) are disposed in a manner "and are made of a soft material such as rubber. The I-wheel is specifically a well-known (four) roller. Moreover, the clamping roller of the pair, the middle of the wheel to the y side is a driving roller, and the second speed can be arbitrarily adjusted and the 疋a is set to be movable up and down, so that the pressure of the second clamping portion 2 can be appropriately adjusted as needed ( Clamping pressure). The third holding portion 3 has a long-shaped release film 32 (a laminate of a heavy release film and an adhesive layer) from which the light release film 31 has been peeled off, and is oriented toward a predetermined step (for example, bonding with a polarizing film) The function of the step (not shown: for example, a bonding device) is continuously carried. The pair of holding rollers forming the third holding portion 3 are provided in such a manner that their axial cores (central axes) are parallel to each other and are made of a soft material such as rubber, and the adhesive layer is not easily attached (actually, The material f to be attached is formed of a material which has been subjected to a well-known release treatment on its surface. Further, at least one of the pair of holding rollers is a driving roller, and the rotation speed thereof can be arbitrarily adjusted, and is set to be movable up and down, so that the pressure of the third holding portion 3 can be appropriately adjusted as needed (nip pressure) ). Further, the heavy release film 32 (the laminate of the heavy release film and the adhesive layer) in the film laminated body 30 is carried out from the first holding portion 1 and then passed through the peeling roller 4, the guide roller 7, and the carrying roller 9. Carry to the third roller 3. On the other hand, the light-peeling film in the film laminate 3 is transported to the second lost portion 2 via the _roller 4, the guide rollers 5 and 6 and the conveyance roller 8 after the first nip 1 is carried out. . In addition, between the two temples 1 and the second holding portion 3 of the upper 322923 14 201200944:32, the heavy peeling thin one, the Jie surname, the system (tension control) are often fixed, and the above tension is constant. ! Between the second holding portion 2 and the tension 疋 of the light peeling film 31 to be conveyed is controlled (tension control) and is often constant. The ship=roller 4 is disposed on the downstream side of the first nip 1 (the downstream side in the direction of the film laminate = 2) in a moving and egg manner with the heavy peeling film 32 30 in the film laminate 3G, and has a light peeling effect. The film Μ builds up from the film and the work of pain. The peeling roller 4 is a non-driven conveying roller, and is formed of a soft material such as rubber or a hard material such as metal. The peeling roller 4 may specifically be a well-known ("general" roller). Further, the separation roller 4 changes the conveyance direction of the above-mentioned heavy release film 32 with respect to the conveyance direction of the above-mentioned (4) from the film 31. That is, the heavy release film 32 in the film laminate 30 that is in contact with the peeling roller 4 can be carried by being wound around the peeling roller 4 (along the peeling roller 4) to change its conveyance direction (direction of travel). In addition, the light release film 31 is conveyed without being wound around the peeling roller 4 (the conveyance direction does not change). Thereby, the peeling roller 4 causes the film laminate 30 to be continuously separated into a heavy release film (a laminate of a heavy release film and an adhesive layer) and a light release film 31. The guide rollers 5, 6, and 7 are non-driven rollers, and are formed of a soft material such as rubber or a hard material such as metal. The guide rollers 5, 6, 7 may in particular be well known (general) rollers. Further, the guide rollers 5, 6 改变 change the conveyance direction of the light release film 31, and the guide roller 7 changes the conveyance direction of the heavy release film 32. The guide roller 5 is disposed on the downstream side of the peeling roller 4 (the downstream side in the conveyance direction of the light release film 31) so as to be in contact with the surface of the light release film 31 which is not bonded to the side of the adhesive layer 15 322923 201200944. The guide roller 6 is disposed on the downstream side of the guide roller 5 in contact with the surface of the light release film 31 that is not bonded to the side of the adhesive layer. The guide roller 7 is disposed on the downstream side of the peeling roller 4 so as to be in contact with the surface of the heavy peeling film 32 that is not bonded to the side of the adhesive layer (the downstream side of the transporting direction of the heavy peeling thin film 32). The rollers 5 and 7 are arranged such that the angle 0 of the conveyance direction of the heavy release film 32 with respect to the conveyance direction of the separation 31 is, for example, preferably 35. Above, 180. Hereinafter, it is more preferably 60. Above, 120. the following. Thereby, the light release film 31 can be continuously and more stably peeled off from the film laminate 3 to prevent the adhesive layer from remaining on the side of the light release film 31. The "transport rollers 8, 9 are non-retro wheels" are formed of a soft material such as rubber or a hard material such as metal. The transport rollers 8 and 9 can be specifically known as a general-purpose roller. It is disposed on the downstream side of the guide = wheel 6 so as to be in contact with the surface of the light release film which is not bonded to the side of the adhesive layer. The conveyance roller 9 is affixed to the surface of the heavy release film. The method of money (4) is on the side of the material. The '8' is provided with a measuring portion (10) for measuring the tension of the heavy phase 32 when the upper (four) wheel 9 is provided. Therefore, the carrying rollers 8 and 9 are the tension sensing rollers (tensi〇n pick up). The upper four jaws lGa and lGb may be well-known (“general” tension gauges 322923 16 201200944. The measurement data measured by the measurement units 10a and 10b is output to a control unit to be described later. Further, the second holding unit 2 is disposed on the downstream side of the conveyance roller 8 (on the downstream side in the conveyance direction of the light release film 31). On the downstream side of the conveying roller 9 (downstream of the conveying direction of the heavy peeling film 32) The third holding portion 3 is disposed on the side. The peeling device 20 includes measurement data input from the measurement units 10a and 10b, and is controlled (adjusted) to form the first holding portion 1 according to the analysis result. The control unit (not shown) of various conditions such as the number of rotations of the second gripping unit 2 and the third gripping unit 3 and the pressure (nip pressure) of the gripping roller 3. Further, the control unit specifically reports on the result of the analysis. The control device can be input (instructed) in advance by the user of the operator, etc. The peeling device 20 having the above-described structure is controlled by the control unit (tension control) to control the tension and heavy peeling of the light release film 31. The tension of the film 32 is fixed to each other, and therefore, the tension of the light peeling film 31 to be conveyed and the tension of the heavy release film 32 are fixed and are not changed, so that the light release film 31 and the heavy release film 32 are removed. It is not easy to cause wrinkles, and there is no fear that the peeling position will move from the peeling roller 4 (the peeling position can be stabilized). Therefore, the light peeling film 31 can be stably peeled off to prevent the adhesive layer from remaining. On the side of the light release film 31, it is possible to provide a peeling device which can continuously and stably peel the light release film 31 from the film laminate 30 so that the adhesive layer does not remain on the side of the light release film 31. According to the peeling device 20 having the above-described structure, the peeling method for peeling the light release film 31 from the long film laminated body 30 is said to be 17 322923 201200944, and the film is laminated. The preparation of the light release film and the d-phase mounting (holding) in each of the clamping portions and the like has been completed. First, the first clamping portion!, the second clamping portion 2, and the second clamping portion 3 are respectively driven by driving. The roller is clamped to carry the film laminate 3, the light release film 31, and the heavy release film 32 by the respective fixed tensions (and speeds). Specifically, the first clamping portion is formed by adjusting! And the rotation speed of the nip roller of the second nip portion 2, that is, the tension of the light release film 31 conveyed by adjusting the rotation speed of the nip roller forming the second nip portion 2 (tension control) Often fixed. And controlling (tension control) by adjusting the rotation speed of the clamping roller forming the first missing portion 1 and the third clamping portion 3, that is, by adjusting the rotation speed of the clamping roller forming the third clamping portion 3 The tension of the transported heavy release film 32 is kept constant. The tension of the light peeling film 31 to be conveyed and the tension of the heavy peeling film 32 are preferably controlled (tension control) at 50 Ν α, respectively, to be more preferably controlled to 100 Å or more. Further, it is preferable that the tension of the heavy release film 32 to be conveyed is larger or equal to the tension of the light release film 31. Thereby, the light peeling film 31 can be continuously and more stably peeled off from the film laminated body 30 so that the adhesive layer does not remain on the side of the light release film 31. In addition, the conveyance speed of the light peeling film 31 conveyed and the conveyance speed of the heavy peeling film 32 can be set suitably according to the material, the nature, thickness, and the above-mentioned tension of these films, and it is not specifically limited, but it is about lm/miri. Above, 3〇m/min or less is more preferable. By continuously carrying out the film laminated body 30 from the first holding portion 1 and continuously conveying the light release film 31 and the heavy release film 32 by the above tension, the light release film 31 is made from the film laminate body on the peeling roller 4 at 18 322923 201200944. Continuous and stable peeling. Next, the long strip-shaped peeling film 31 passes through the second holding portion 2 via the guide rollers 5, 6 and the conveying roller 8, and is wound around the winding portion (not shown). On the other hand, the long heavy peeling film 32 passes through the third holding portion 3 via the guide roller 7 and the conveyance roller 9, and is directed to a device for performing the next step (for example, a bonding step with a polarizing film) (not shown). : For example, a bonding device) is continuously carried. According to the above-described peeling method, the tension of the light release film 31 conveyed by the control (tension control) and the tension of the heavy release film 32 are fixed to each other, that is, the tension and the heavy peeling of the light peeling film 31 to be carried. Since the tension of the film 32 is fixed and does not change, the light release film 31 and the heavy release film 32 are less likely to wrinkle, and there is no fear that the peeling position will move from the peeling roller 4 (the peeling position can be stabilized, therefore, The light release film 31 can be stably peeled off so that the adhesive layer does not remain on the side of the light release film 31. Thereby, it is possible to provide a light release film continuously and stably peeled off from the film laminate 30 to prevent the adhesive layer from remaining. The peeling method on the side of the light release film 31. The heavy peeling film 32', that is, the long heavy peeling film 32 which peels the light release film „.3.1 from the adhesive layer is used, for example, in an optical film, such as a polarizing plate, or various The production of the optical member may be performed by the pair of rollers in the peeling device 2 of the present embodiment. One of the rollers is in contact with the side of the heavy release film 32 in the film laminate 30, and the other roller is in contact with the side of the light release film 31 in the thin layered body 30, except for the direction of the heavy release film 322923 19 201200944 5 The conveyance direction of the light release film 31 is also changed to be peeled off, that is, by changing the conveyance direction of the heavy release film 32, while the red release film 31 is wound around the roller (making it follow the roller) : changing the conveyance direction of the film laminate 3 is continuously separated into a heavy release film 32 (a laminate of a heavy release film and an adhesive layer) and a light release film is formed in the above structure. The light release film 31 is continuously and stably adhered from the film laminate 30 so that the adhesive does not remain on the side of the light release film 31. The device 2G of the present embodiment is suitable for the wire as a continuous bonding of the polarizing plate, for example. A sheet-like liquid crystal panel is a part of a manufacturing apparatus using a so-called roller-to-panel method for manufacturing a liquid crystal display device. Here, a long strip-shaped peeling film (a layer of a heavy peeling film and an adhesive layer) is laminated. The following is a description of a method for producing a polarizing plate (a polarizing film original plate) using a heavy release film, a method for producing a liquid crystal panel using a polarizing plate, and a manufacturing apparatus thereof. The polarizing plate is a polarizing film. The protective film (that is, the heavy release film) and the adhesive layer are formed. The polarizing film may be a well-known polarizing film. More specifically, the polarizing film may be a film on both sides of the polarizing film, and the protective film is formed on the protective film. A polarizing film known in the art of an adhesive layer. One of the adhesive layers is for adhering a release film (that is, a heavy release film having a different property from a heavy release film forming the protective film). The polarizing film is incorporated, and a polarizing film is bonded to the liquid crystal panel. In the above adhesive layer, the other adhesive layer is formed by bonding a protective film to a polarizing film at 322923 20 201200944. The thickness of the above protective film is not particularly limited, but is approximately 10 // m or more and 10 0 /z m or less. The thickness of the adhesive layer can be appropriately set. The thickness of the release film is not particularly limited, but is preferably about 10/m or more and 100 #m or less. The polarizer film may be, for example, a film composed of polyvinyl alcohol, a partial methylal polyvinyl alcohol, a partial saponified product of an ethylene-vinyl acetate copolymer, or a hydrophilic polymer such as cellulose, and uniaxially stretched. A dyeing treatment of a dye such as iodine, and a film subjected to various treatments such as hue adjustment. The protective film may be, for example, a TAC (triethylenesulfonyl cellulose) film, a cycloolefin resin film, a cellulose acetate resin film such as diethyl phthalocyanine, a polyethylene terephthalate or a polyethylene naphthalate. A well-known film such as a polyester resin film such as a diester or a polybutylene terephthalate, a polycarbonate resin film, an acrylic resin film, or a polypropylene resin film. The thickness of the polarizing film is not particularly limited, but is approximately 10 μm or more and 300 #111 or less. The polarizing film can be practically used in a range that does not cause any hindrance, and has other layers in addition to the above three layers (protective layer, polarizing film, and protective layer). Specifically, for example, the polarizing film may further have an adhesive layer (which may be an adhesive layer) for bonding the polarizing film and the protective film. The polarizing plate manufacturing apparatus is a long-length peeling film which is bonded to the peeling film or the protective film through the adhesive layer on both sides or one side of the long-length polarizing film. Specifically, the polarizing plate manufacturing apparatus includes: a conveying roller that conveys a polarizing film at a fixed speed; and a heavy peeling film or a group or two sets of conveying rollers that have different films from each other at a fixed speed of 21 322923 201200944; And the bonding means of the nip portion having the two kinds of heavy peeling and heavy peeling film bonding is to carry out the heavy peeling film phase while performing the polarizing film forming apparatus. Polarized light 5 = Light plate is calibrated, and the two are transported to the position where the pressure of the bonding device is 1 = the pressure (nip pressure) and the heavy release film is attached to the polarized light plus the predetermined action. 'Insulin, the above-mentioned polarizing plate manufacturing device can also be used for thinning two kinds of heavy peeling films for polarizers>> or for holding a heavy peeling film with one heavy peeling off for the polarizer = device clamping portion. (Clamping) (4) The structure for manufacturing the polarizing plate, or the bonding device: The part 'make the side of the central holding part (clamping) - the side of the heavy peeling thin film and fit it after the other side The holding part is held (clamped) =: The structure of the polarizing plate is produced by the film and the double peeling film which is bonded to each other and bonded together. In this way, a long polarizing plate (a long polarizing plate bonded to a long release film) can be produced. When the gastric polarizing plate is attached to the liquid crystal panel, it is bonded to the two heavy release films of the polarizing film. The heavy release film forms a protective film, and the other heavy release film forms a peeling film. film. Since the strip-shaped polarizing plate has different peeling forces of the two kinds of heavy-duty thin films, the heavy-duty film side on which the protective film is formed is wound around 322923 22 201200944 so as to be an elongated polarizing film original plate. Therefore, the polarizing film original plate is a long-length polarizing film laminate composed of a polarizing film, an adhesive layer, a protective film, and a release film, and penetrates the adhesive layer on the surface of the polarizing film which is bonded to the side of the liquid crystal panel. A peelable release film may be bonded to the adhesive layer, and a protective film may be bonded to the back surface of the surface through an adhesive layer (or an adhesive layer). That is, the adhesive layer, the polarizing film, the adhesive layer and the protective film are laminated in this order by peeling the film, and a polarizing plate is formed. The polarizing film original plate is composed of a polarizing plate and a release film. The release film (also referred to as a protective film or a separator) protects the surface of the polarizing plate (the surface that is bonded to the side of the liquid crystal panel) before the polarizing plate is attached to the liquid crystal panel to prevent damage, and the polarizing plate is used. When it is bonded to the liquid crystal panel, it is peeled off from the polarizing plate. Next, the polarizing plate cut from the original polarizing film to a predetermined length is attached to the entire display area of the liquid crystal panel (the entire portion where the surface of the display is formed) by two bonding steps. Both sides of the LCD panel. The liquid crystal panel can be a well-known liquid crystal panel. More specifically, the liquid crystal panel may be a well-known liquid crystal panel in which a substrate such as a pair of glass substrates and a liquid crystal layer are formed, and an alignment film is disposed between the substrate and the liquid crystal layer. The polarizing film original plate is wound up by a polarizing film transport mechanism (not shown), and the polarizing plate peeled off from the release film can be supplied to the nip portion of the bonding apparatus. Hereinafter, the above-described polarizing film transport mechanism will be described. The polarizing film transport mechanism includes a winding portion, a winding portion, a half cutter, a 23 322923 201200944 blade edge, and a roller group. For her, she used a long strip of polarizing film to roll out the 13⁄4 polarizing film as the 々η I" 。 plate. The polarizing film was taken in the direction of the general direction of the polarizing film. The winding method is wound up in the unwinding portion. Roll =: a long strip-shaped separation film. The roller group is provided for the polarizing thin film, and the original film of the polarizing film is transported. The transport mechanism can take up the long polarized thin phosphine crucible wound in a roll shape and transport it to the release film. The device 'and the unwound long strip half cutter are set on the original film of the polarizer film. And (4) the upstream side of the f (the side of the unwinding portion), which can be half-cut, that is, half-shear. The β-polarized polarizing film, the protective film, and the adhesive layer are broken into predetermined parts = the cutter is not cut off from the film. The long strip-shaped polarizing plate cuts the net 4: α length. The half-cutter is suitable for using a cutter, a laser cutter, etc., and the well-known cutter is used. An adhesive needle that is cut into a predetermined long layer between the peeling and the polarizing plate (four) from the film Using the paste 'eight remains in the polarizing plate side. ^ ^ ^, Κ ^ 5 apparatus (and the polarizing film conveyance mechanism), so that the biasing

Further, by performing the two-feeding step, a liquid crystal display device in which a polarizing plate is bonded to both surfaces of the liquid crystal panel can be manufactured. This is obvious after the modularization, but also the various assembly steps, but silly into a mobile computer such as a notebook PC or mobile phone, or even a large TV set and other products (final products). [Embodiment 2] Another embodiment of the present invention will be described with reference to Fig. 2, as will be described below. In addition, in the present embodiment, the structure similar to the structure of the above-mentioned embodiment 322923 25 201200944 is omitted, and the description thereof is omitted as shown in Fig. 2. The peeling device 21 of the present embodiment is a replacement device. The peeling roller 4 of 20 is provided with a variable peeling 2 14, and the variable guide roller 15 is provided instead of the guide roller 5. The other member of the two-way member 21 is the same as the member constituting the peeling device 20, and the i-variable peeling roller 14 is disposed in the first holding portion so as to be in contact with the side of the heavy peeling film 5 in the film laminated body 3A. The downstream side of the crucible has a function of continuously peeling the light release film 31 from the film laminate 30. The peeling roller 14 is a non-driven conveying roller and is formed of a soft material such as rubber or a hard material such as metal. The variable peeling roller 14 can be specifically a roller that is well known. Further, the variable peeling roller 14 can change the conveyance direction of the upper peeling film 32 with respect to the conveyance direction of the light release film 31. That is, the heavy-peeling roller 3 2 of the film laminate 3 in contact with the variable peeling roller 14 is changed in its conveying direction by being wound around the variable peeling roller 4 (along the variable peeling roller 14) ( In the traveling direction, the light release film 31 is conveyed without being wound around the variable peeling roller 丨 4 (the conveyance direction is not changed). Thereby, the variable peeling roller 14 continuously separates the film laminated body 30 into the heavy release film 32 (the laminated body of the heavy release film and the adhesive layer) and the light release film 31. The variable guide roller 15 is a non-driven roller and is formed of a hard material such as rubber or a hard material such as metal. The variable guide roller 15 may specifically be a well-known (general) roller. The variable guide roller 15 is disposed on the downstream side of the variable peeling roller 14 so as to be in contact with the surface of the light release film 31 that is not bonded to the side of the adhesive layer (the conveyance direction of the light release film 31 is 26 322923 201200944) 'Travel side'. Further, the variable guide roller 15 changes the conveyance direction of the above-described light release film 31. Further, the variable peeling roller 14 and the variable guide roller 15 are housings (not shown) movably provided in the peeling device 21. Specifically, the variable peeling roller 14 and the variable guide roller 15 can be made of the type of the film laminate 3, that is, for the material, properties, thickness, etc. of the light release film 31, the adhesive layer, and the heavy release film 32. The most appropriate peeling action of various conditions is such that the arrangement (moving position) can be changed, and the angle 0 of the conveying direction of the heavy peeling film 32 with respect to the conveying direction of the light release film 31 can be, for example, preferably 35. Above, 180. In the following range, it is more preferably 6 inches. The above is arbitrarily changed within the range of 120 or less. Therefore, the variable peeling roller 14 also has a function as a variable guide roller. On the other hand, the guide rollers 6, 7 are fixed to the frame (not shown) of the peeling device 21, and have a function as a fixed guide roller. That is, even if the arrangement of the variable peeling roller 14 and the variable guide roller 15 is changed (moving position), the conveyance direction of the light release film 31 from the variable guide roller 15 toward the guide roller 6 is changed, also because of the guide roller Since the arrangement (position) of 6 is fixed and the positional relationship with the conveyance roller 8 does not change, the conveyance direction of the light release film 31 from the guide roller 6 toward the conveyance roller 8 can be kept constant. Similarly, even if the arrangement of the variable peeling roller 14 and the variable guide roller 15 is changed by changing (moving position), the conveying direction of the heavy peeling film 32 from the variable peeling roller 14 toward the guiding roller 7 is changed, and also because of the guiding roller The arrangement (position) of 7 is fixed, and the positional relationship with the conveyance roller 9 does not change. Therefore, the conveyance direction of the heavy peeling film 32 from the guide roller 7 toward the conveyance roller 27 322923 201200944 9 can be kept constant. In the peeling device 21 of the present embodiment, since the guide roller 6 belonging to the fixed guide roller is provided between the variable guide roller 15 and the conveyance roller 8, the conveyance direction of the light release film 31 toward the conveyance roller 8 is maintained. for sure. That is, the angle of the light-peelable film 31 of the transport roller 8 (described later) can be kept constant. Therefore, the measurement of the tension of the light release film 31 by the measuring unit i〇a provided in the transport roller 8 can be stably performed. Similarly, in the peeling device 21 of the present embodiment, since the guide roller 7 belonging to the fixed guide roller is provided between the variable peeling roller 14 and the conveyance roller 9, the conveyance direction of the heavy release film 32 toward the conveyance roller 9 is maintained. for sure. That is, the wrap angle of the heavy peeling film 32 of the conveyance roller 9 can be kept constant. Therefore, the measurement of the tension of the heavy peeling film 3 2 by the measuring unit 10 b provided on the conveying roller can be stably performed. Further, a variable guide roller having the same configuration as that of the variable guide roller 15 is provided between the variable roller 14 and the material roller 7. In the second case: the peeling roller 14 does not have (not both) as the variable guide roller. The "angle" in the heavy moon indicates that the film (light peeling film 3 heavy peeling film 32) is wound around The scale at which the film is transported to the edge of the film and the degree of the conveyance of the roller is the angle (in the case of the 士, #士人, while the conveyance is being conveyed and the direction of conveyance is changed). ).罝 180 When the W-ring is wound, the film is transporting the rollers 8, 9 coffee. 'Wrap 1/4_ case T will change f 6G. Therefore, the angle of the turn is ', and the direction of conveyance will change by 90. Therefore, the angle of 322923 28 201200944 is 90°, and when it is wound by 1/3 turn, the conveying direction will change by 120. Therefore, the corner angle is 60. When the winding is 1/2 turn, the conveying direction will change by 180. Therefore, the corner is 〇. . In the peeling device 21 of the present embodiment, since the positional relationship between the guide roller 6, the conveyance roller 8, and the second holding portion 2 is constant, the winding angle of the light release film μ in the conveyance roller 8 is constant. . Similarly, in the peeling device 21 of the present embodiment, the positional relationship between the guide roller 7, the conveyance roller 9, and the third holding portion 3 is constant, and therefore the angle of the heavy peeling film 32 in the conveyance roller 9 is constant. It is certain. Therefore, even if the angle of the conveyance direction of the heavy release film 32 with respect to the conveyance direction of the light release film 31 is changed according to various conditions such as the material, the property, and the thickness of the film laminate 30, the light release film 31 and the weight can be stably measured. Since the tension of the film 32 is peeled off, the tension of the light peeling film 31 and the heavy peeling film 32 to be conveyed can be controlled to be constant. That is, according to the peeling device 21 of the above configuration, even if the conveyance direction of the heavy release film 32 is changed by the angle 0 with respect to the conveyance direction of the light release film 31, the conveyance rollers 8, 9 can be made light by the guide rollers 6, 7. The corners of the release film 31 and the heavy release film 32 are fixed. In other words, the measurement conditions of the tension of the light release film 31 and the tension of the heavy release film 32 by the measurement head portions 10a and 10b can be kept constant, so that the tension control can be performed more stably by the control unit. Therefore, the peeling device 21 according to the above configuration can change the angle of the conveyance direction of the heavy release film with respect to the conveyance direction of the light release film 31 depending on the kind of the film laminate 3〇, and thus the light release film 31 can be provided. A peeling device that is continuously and more stably peeled off from the film laminate 322923 29 201200944 30. Further, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Therefore, various modifications can be made in the scope of the claims. INDUSTRIAL APPLICABILITY According to the peeling method and the peeling device of the present invention, since the tension of the lightly peeling film to be conveyed and the tension of the heavy peeling film are constant and do not fluctuate, the light release film can be stabilized.
