201208843 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種積層體膜之切斷裝置刀 ^檟層體膜之切 斷方法。 【先前技術】 先前，作為功能性膜，將光學膜'導雷腹 干电犋、保護膜、配 電板用膜、轉印膜等各種膜用於各種用途。該等膜為積層 體膜者較多，將保護膜自藉由保護膜所保護之膜除去後， 黏貼於其他之膜或基板等而製造積層膜。 作為具體例，於製造液晶顯示面板之情形時，通常將於 偏光膜上藉由黏著劑黏貼有保護膜之長條之積層體膜經由 生產線搬送，並於除去保護膜後進行與基板之黏貼。、於黏 貼前，將偏光膜及黏著層於流動方向切斷成短條，作並不 切斷保護膜’形成所謂的半切穿。藉此，切斷成短條之偏 光膜黏貼至基板，被除去之長條之保護膜 形成半切穿時，對膜之切斷刀之切入深度之成調卷整:為重 要。此係因為’若過深，則會切斷保護膜，若過 法切斷偏光膜。 關於此方面’專利文獻1中揭示有可高品質地對積層體 膜進行半切穿之半切穿裝置。專利文獻1之半切穿袭置包 括壓輥。該壓輥係用於推壓並保持作為切斷對象之感光性 满狀物者藉此’可於將旋轉圓刀之切斷深度保持在特定 之值之狀態下進行半切穿。 又’專利文獻2中揭示有包括與壓輥相同之推壓報之切 156494.doc 201208843 斷裝置。 [先前技術文獻] [專利文獻] [專利文獻1

係專利文獻1、2中揭示之裝置藉由壓輥推壓感光性網狀 物。此處，本發明者等人著眼於感光性網狀物有厚度之起 伏自不必說，亦著眼於切割台（切斷台）本身微觀上並不平 滑。 專利文獻1、2中之壓輥配置於感光性網狀物上，難以隨 著切割台之微妙的歪曲而調整旋轉圓刀之位置。於此方 面，專利文獻卜2中存在問題，故無法正確地對積層體膜 進行平行之半切穿。 進而’為平行地進行半切穿，對切割台亦要求將使切斷 裝置i滑動之LM(Linear M〇ti〇n，直線滾動）導軌設置於切 斷方向上之設置精度。然、而，切割台具有偏光膜之寬度以 上之長度’通常為長條⑷侧_以上等因此，進行 正確的設置非常因難。 156494.doc 201208843 因此，為較先前對積層體膜進行更加平行之半切穿，本 發明者等人進行銳意研究，結果發現：並非以切斷對象之 表面為基準進行切斷刀之刀尖之位置調整，而是以切斷台 為基準進行切斷刀之刀尖之位置調整。 本發明係繁於上述先前之問題而開發者，其目的在於提 供一種可使切斷刀之刀尖與切斷台保持更加平行之狀態下 進行半切穿之積層體膜之切斷裝置。 [解決問題之技術手段] 為解決上述課題，本發明之積層體膜之切斷裝置係藉由 包括將積層體膜中的一部分之膜切斷之切斷力，使切斷刀 石著支撐積層體膜之切斷台移動，從而將積層有複數個膜 之積層體膜中的-部分之媒切斷者，其特徵在於：包括相

移感測器而測量針盤量規或位移感測器與切斷台之距離， 從而可根據該距離資訊控制切斷刀調整部，以使切斷刀之 切斷方向與切斷台平行。該切斷裝置並非根據關於積層體 、貝机’而是根據與切斷台之距離資訊進行切斷刀調整 ^之控制’故可使切斷刀之刀尖與切斷台保持更加平行之 156494.doc 201208843 狀態。 [發明之效果] 如上所述，本發明之積層體膜之切斷裝置係包括相對於

又，刀具單元7與切斷台20相對向而設置。切斷台2〇係 置作為切斷對象之積層體膜者。作為積層體膜並未特別 限疋可以光學膜、導電膜、保護膜、配電板用膜、轉印 膜等各種積層體膜為對象。 本發明之切斷裝置1即便於上述膜令亦可較佳地用於將 相對於偏光膜介隔黏著層而積層有保護膜之積層體膜切斷 之用途。通常偏光膜係與基板黏貼之前階段，於長條之狀 態下且於表面由保護膜所保護之狀態下被搬送，將偏光膜 及黏著層切斷。於以長條被搬送之過程中，必須依序切斷 偏光膜及黏著膜，故可稱偏光膜為較佳之切斷對象。 作為上述偏光膜使用公知之偏光膜即可。本發明中之偏 光膜係使用通f之長條偏光膜。具體而言，構成為於偏光 子膜之兩面黏貼TAC(TriacetylceIluI〇se，三醋酸纖維素）膜 I56494.doc 201208843 等作為保護膜，進而於一方或雙方之TAC膜上介隔黏著劑

飼服馬達5為可控制線性單元3似導軌之結構，如於圖4 中如下所述，可調整刀具單元7之刀尖之深度。 位於刀具單元7之下部之刀具單元用lm導軌9係使刀具 单兀7於刀具調整方向移動，刀具單元7介隔銷6自轴承單 704朝方向c被推壓’藉此朝方向C移動。或者，刀具單元 7由退刀用彈*8朝方向’藉此朝方向d移動:刀且 單元用LM導執9與控制部連結，藉由控制部之控制而沿: 具調整方向移動。

I56494.doc 201208843 傾斜（約6。）。又，兩個傾斜亦可隨著朝向方向A而形成。 第1較大之傾斜係用於使刀具單元7較大地移動時。另一 方面，第2較緩之傾斜與軸承單元4接觸時之刀具單元7之 位置較理想的是為所需之刀具深度。藉此，於第2較緩之 傾斜之範圍内調整銷6，有易調整微妙之刀具深度之優 點。再者，銷6之上述兩個傾斜角並不限定於上述角度。 又，銷6亦可不具有複數個傾斜，即便僅為固定之傾斜， 亦當然可進行積層體膜之切斷。 使用圖4就刀具單元7之位置調整進行說明。_係表示 切斷裝置1之平面圖。如圖4所示，刀具單元7係藉由退刀 用彈簧8朝方向〇施加負荷，於被軸承單元*推壓之狀態下 保持其位置。此處，若軸承單元4朝方向A移動，則刀具單 ^7以不與銷6產生間隙之方式朝方μ移動ϋ面， 右軸承單兀4朝方向Β移動，則銷6被軸承單元4朝方向C推

Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for cutting a film of a laminated body film. [Prior Art] Conventionally, as a functional film, various films such as an optical film 'lead dry electricity dry wire, a protective film, a film for a power distribution plate, and a transfer film have been used for various purposes. These films are often laminated film films, and the protective film is removed from the film protected by the protective film, and then adhered to another film or substrate to produce a laminated film. As a specific example, in the case of manufacturing a liquid crystal display panel, a laminate film in which a long film of a protective film is adhered to a polarizing film is usually conveyed through a production line, and after adhesion to a substrate, adhesion to a substrate is performed. Before the adhesion, the polarizing film and the adhesive layer are cut into short strips in the flow direction to form a so-called half cut without cutting the protective film. Thereby, when the polarizing film cut into a short strip is adhered to the substrate, and the long protective film is formed to be half-cut, it is important to adjust the depth of the cutting blade of the film. This is because if it is too deep, the protective film is cut and the polarizing film is cut off. In this regard, Patent Document 1 discloses a half-cut device capable of performing half-cutting of a laminated body film with high quality. The half cut wear of Patent Document 1 includes a press roll. The pressure roller is used to press and hold the photosensitive full object to be cut, whereby the half cut can be performed while maintaining the cutting depth of the rotary cutter at a specific value. Further, Patent Document 2 discloses a 156494.doc 201208843 breaking device including the same pressing report as the pressure roller. [PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2007-260865 (published on October 11, 2007) [Patent Document 2]曰 专利 专利 专利 专利 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) There is a problem that the device cannot correctly perform parallel half-cutting of the laminated body film. Specifically, the apparatus disclosed in Patent Documents 1 and 2 pushes the photosensitive web by a press roll. Here, the inventors of the present invention have focused on the thickness of the photosensitive web, and it is also necessary to pay attention to the fact that the cutting table (cutting table) itself is not microscopically smooth. In the patent documents 1 and 2, the pressure roller is disposed on the photosensitive web, and it is difficult to adjust the position of the rotary cutter with the subtle distortion of the cutting table. In this regard, there is a problem in Patent Document 2, and it is impossible to correctly perform parallel half-cutting of the laminated body film. Further, the half-cutting is performed in parallel, and the setting accuracy of the LM (Linear M〇ti〇n) guide rail for sliding the cutting device i in the cutting direction is also required for the cutting table. However, the cutting table has a length above the width of the polarizing film, which is usually a length (4) side or more, and therefore it is very difficult to perform correct setting. 156494.doc 201208843 Therefore, the inventors of the present invention conducted intensive studies to obtain a more parallel half-cutting of the laminated body film, and found that the position of the cutting edge of the cutting blade is not based on the surface of the cutting object. The adjustment is made, and the position of the cutting edge of the cutting blade is adjusted based on the cutting table. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a cutting device for a laminated body film which can be half-cut through a state in which the cutting edge of the cutting blade and the cutting table are kept in parallel. [Means for Solving the Problem] In order to solve the above problems, the apparatus for cutting a laminated body film of the present invention supports the laminated stone by a cutting force including cutting a part of the film of the laminated body film. When the cutting unit of the body film is moved to cut the medium portion of the laminated body film of the plurality of films, the cutting of the cutting blade is adjusted with respect to the cutting table. a knife adjustment unit, a dial gauge or a displacement sensor for measuring a distance, and a control unit for controlling the cutter adjustment unit, wherein the control unit is cut according to the measurement by the dial gauge or the displacement sensor The distance gauge of the dial gauge or the displacement sensor/cutting table in the longitudinal direction of the table controls the cutting blade adjusting portion so as to cut the cutting blade and the cutting table with respect to the laminated body film parallel. According to the above invention, the distance between the dial gauge or the displacement sensor and the cutting table is measured by the dial gauge or the displacement sensor disposed on the cutting device, so that the cutting knife can be controlled according to the distance information. The adjustment portion is such that the cutting direction of the cutting blade is parallel to the cutting table. The cutting device does not control the cutting blade adjustment based on the distance information from the cutting table according to the laminated body or the bay machine. Therefore, the cutting edge of the cutting blade and the cutting table can be kept more parallel. .doc 201208843 Status. [Effects of the Invention] As described above, the cutting apparatus for a laminated film of the present invention includes a cutting blade adjusting portion for adjusting the position of the cutting blade with respect to the cutting table, and a dial gauge or displacement for measuring the distance. a sensor and a control unit for controlling the cutting blade adjusting unit, wherein the control unit is based on a dial gauge or displacement sensing of a length of the cutting table measured by the dial gauge or the displacement sensor The distance information between the device and the cutting table is controlled to control the cutting blade adjusting portion so that the cutting direction of the cutting blade with respect to the laminated body film is parallel to the cutting table.

Moreover, the following description of the drawings can be understood. [Embodiment] And the aspects of the present invention are as follows according to the advantages of the present invention. The present invention is as follows according to Figs. 1 to 6 . Furthermore, the product of the present invention is described in the form of a fourth embodiment, and the cutting device of the present invention can be used in the method of cutting the laminated body film and using the cutting device of the present invention: 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 In addition, for convenience of explanation, the drawings of the control unit, the dial gauge, and the like are omitted. The configuration of the dial gauge and the like will be described below using Fig. 6 . Further, a magnetic base (not shown) in the figure is disposed in the area χ on the linear unit 3. As shown in Fig. 1, the cutting device 丨 includes a main base 2 as a base, a linear unit (cutting blade adjusting portion) 3, a bearing unit 4, a servo motor 5, a stalker 6, and a cutter unit (cutting knives) ) 7 and retracting spring 8 etc. Although not round, the cutting device 1 is provided on the linear motor sliding portion. The linear motor slide portion is a member that slides by a linear motor and moves the cutting device 1 along the cutting table 20 when the laminated body film is cut. Further, the cutter unit 7 is provided to face the cutting table 20. The cutting table 2 is attached to the laminated body film to be cut. The laminated body film is not particularly limited to various laminated film films such as an optical film, a conductive film, a protective film, a film for a power distribution board, and a transfer film. The cutting device 1 of the present invention can be preferably used for cutting a laminated body film in which a protective film is laminated with respect to a polarizing film with an adhesive layer interposed therebetween. Usually, before the polarizing film is adhered to the substrate, it is conveyed in a state of a strip and protected by a protective film, and the polarizing film and the adhesive layer are cut. In the process of being transported in a long strip, the polarizing film and the adhesive film must be cut in order, so that the polarizing film is preferably a target for cutting. A known polarizing film may be used as the polarizing film. In the polarizing film of the present invention, a long polarizing film of F is used. Specifically, a TAC (Triacetylce IluIsse, cellulose triacetate) film I56494.doc 201208843 or the like is adhered to both sides of the polarizing film as a protective film, and the adhesive is deposited on one or both of the TAC films. Protective film. In the polarizing film, a polarizing film located at the center may be a film obtained by dyeing and stretching a polyvinyl alcohol film with iodine or the like. Further, a partially formalized polyvinyl alcohol-based film, a vinyl acetate-based copolymer partial saponified film, a hydrophilic polymer film such as a cellulose film, or the like, a dehydrated material of polyvinyl alcohol or a polyethylene-gas can be used. A polyene alignment film or the like such as a dehydrogenated hydrogen treatment product is used instead of the above polyethylene glycol film. The total thickness including the polarizing film and the protective film is not particularly limited, and may be, for example, i 〇〇 pm or more and 500 μmη or less. Further, in the polarizing film, the thickness of the sub-film is substantially (7) μπι or more and 50 μηι or less. Further, the above laminated film is practically used as a polarizing film, and may further contain other layers in addition to the above three layers in a problem-free range. The protective film is not particularly limited. For example, various films such as a polyethylene film, a polypropylene film, and a polycarbonate film can be used. In Fig. 1, the surface of the cutting table 20 facing the cutter unit 7 is disposed in the up-down direction. In other words, it is assumed that the laminated body film is cut in half in the shape I is conveyed in the vertical direction. However, the conveying direction of the laminated body film is not limited to the direction and can be changed in various directions. Therefore, the description will be further described using FIG. Fig. 2 is an exploded perspective view showing the cutting device 1, showing the state of the lock and the state of the tool "7. In Fig. 2, the direction of the direction and the direction of the direction (four) is the laminated body film of the object to be cut. In the other way, the two directions indicated by the wide direction C and the direction D are the tool adjustment directions for adjusting the depth of the tool. 156494.doc 201208843 The linear unit 3 shown in Fig. 2 includes the LM guide in the main base side. The LM guide causes the moving object to be placed along the surface of the linear unit 3 along the surface of the linear unit 3 along the LM rail of the unit 3 of the screw so that the bearing unit 4 is half-cut through: The bearing unit supports the components of the pin 6. Further, the feeding motor 5 is disposed in the linear unit 3 toward the end portion. The feeding motor 5 is used to measure the distance from the object to be cut, and adjusts the depth of cut of the cutting edge of the tool unit 7 based on the position of the tool unit 7 that has been memorized. A known person can be used as the feeding motor 5 . The feeding motor 5 is a structure that can control the linear unit 3 like a guide rail, and as described below in Fig. 4, the depth of the cutting edge of the cutter unit 7 can be adjusted. The cutter unit located at the lower portion of the cutter unit 7 moves the cutter unit 7 in the tool adjustment direction by the lm rail 9, and the cutter unit 7 is pushed by the pin 6 from the bearing unit 704 toward the direction c, thereby moving in the direction C. Alternatively, the cutter unit 7 is moved in the direction d by the retracting bullet *8 toward the direction d: the unit is connected to the control unit by the LM guide 9, and is moved in the adjustment direction by the control of the control unit. 3 is a perspective view showing the pin 6 and the cutter unit 7. As shown in Fig. 3, a rotary cutter is used as the cutter of the cutter unit 7 in the cutting device 1. However, the cutting device of the present invention is not limited to the rotary cutter, and a known cutter which is represented by a non-rotating flat knife or the like may be used. As an example, a fixed round knife can be mentioned. The pin 6 is coupled to the table portion holding the cutter unit 7, and moves with the cutter unit 7^. The pin 6 is provided with a tilt in the half-cut direction, and is provided with a larger third inclination (about 17) and a second slower I56494.doc 201208843 tilt (about 6.). Also, the two inclinations may be formed along the direction A. The first larger tilt is used to move the cutter unit 7 relatively large. On the other hand, the position of the cutter unit 7 when the second gentle inclination is in contact with the bearing unit 4 is desirably the required tool depth. Thereby, the pin 6 is adjusted within the range of the second gentle inclination, and the advantage of the subtle tool depth can be easily adjusted. Furthermore, the above two inclination angles of the pin 6 are not limited to the above angles. Further, the pin 6 may not have a plurality of inclinations, and it is of course possible to cut the laminated body film even if it is only a fixed inclination. The position adjustment of the cutter unit 7 will be described with reference to Fig. 4 . _ indicates the plan view of the cutting device 1. As shown in Fig. 4, the cutter unit 7 applies a load to the direction 〇 by the retracting spring 8, and maintains its position while being pressed by the bearing unit*. Here, if the bearing unit 4 moves in the direction A, the tool unit 7 moves the kneading surface toward the square μ so as not to form a gap with the pin 6, and the right bearing unit 4 moves toward the direction ,, and the pin 6 is moved toward the bearing unit 4 The direction C pushes 'there is moving in the direction C. Thus, in the cutting device i, the cutter unit 7 can be moved relative to the cutting table 20 by moving along the cutting table 20 of the bearing ::4. Move in the vertical direction. The movement of the bearing unit 4 is accomplished by controlling the linear saponin 3 and moving its LM guide. This control is completed by the control unit 1G disposed in the area X, and the control unit H) will be explained below using Fig. 6 and the front view of the apparatus 1 will be cut. In Fig. 5, nine are provided in the area X, and the base 11 is further disposed. The front end of the magnetic base 11 is provided with a thin gauge disk. The base 11 supports the dial gauge 12. The magnetic base 11 can be changed to other members that can support the dial gauge 12. I56494.doc 201208843 The dial gauge 12 is in contact with the cutting table 2〇, and measures the distance between the dial gauge 12 and the cutting table 20 at a plurality of locations. That is, it is obtained that the distance information between the dial gauge 12 and the cutting table 2 in the length direction of the cut (4) is obtained. Specifically, the cutting device i is moved along the cutting table by a linear horse sliding unit which is not shown, and the distance information is obtained by the dial gauge 12 during the movement thereof. As described above, the cutting device (1) of the present invention does not control the line 1 and the sheet 7G 3 based on the distance from the cutting table 2 based on the distance from the laminated body film. In this way, it is considered that the prior art has not been cut. After the smoothness of 20, the adjustment of the cutter unit 7 can be performed. (7) The distance information is measured by the dial gauge 12. In the prior method, although a press roll (pushing roll) is used for the surface of the photosensitive web, in such a method, it is difficult to perform the use of the roll and reflect the cut by the presence of the photosensitive web. The measurement of the smoothness of the broken table 20. In this way, in the method of the present invention, since the cutting table 20 is used as a direct measurement object, a dial gauge (or a displacement sensor) that can measure the diameter of the micro/field is used differently from the pressing roller. The fine measurement of the cutting table 20 can be performed. Therefore, the cutting edge of the cutting blade can be kept in a more parallel state with the cutting table. The distance information obtained by the dial gauge 12 is sent to the control unit η and the memory unit 14. The dial gauge 12 is not particularly limited, and it is preferable that the lower limit of the measurable is at least 丨μηι. As long as it has such performance, it is of course possible to use a well-known stylus gauge. Although the dial gauge 12 is used in the cutting device 1, it is also possible to use a displacement feeling instead of it. As the displacement sensor, it is possible to use a laser that illuminates the cutting table 20, preferably with! The resolution of μηι or more. A well-known displacement sensor can be used as long as it is such a position 156494.d〇c 201208843. In the present specification, 'the cutting device 1 including the dial gauge 12 or the displacement sensor has been described' but can also be cut off by not including the magnetic base u and the dial gauge 12 or the displacement sensor. The device cuts a part of the film of the laminated body film. In this case, first, the distance information measured by the dial gauge 12 or the displacement sensor of the cutting device 1 is obtained in advance. The distance information can be saved in a memory medium such as a memory. When the distance information is transmitted to the control unit 13 and the memory unit 14 in the cutting device that does not include the dial gauge 12 or the displacement sensor, a part of the film in the laminated body film can be cut. According to this configuration, the distance information using the dial gauge 12 or the displacement sensor can be obtained once, and the tact time necessary for obtaining the distance information can be reduced. Further, the position information of the blade edge of the cutter unit 7 with respect to the cutting table 2 is additionally obtained by the tool edge position information obtaining means. The position information of the cutting edge is transmitted to the control unit 13 and the storage unit 14, and the linear unit 3 is controlled by the control unit 13 so that the cutting direction of the cutter unit 7 with respect to the laminated body film is parallel to the cutting table 20. A known camera can be used as the obtaining means for the above-described tool tip position information. The control unit 13 controls the linear unit based on the distance information between the dial gauge 12 and the cutting table 20 measured by the dial gauge 12 (which is a displacement sensor when the displacement sensor is replaced by the dial gauge). 3. The cutting direction of the cutting blade of the cutter unit 7 with respect to the laminated body film is parallel to the cutting table 2A. The control unit 13 includes a CPU (central processing unit) that executes a command for implementing a control program for each function, and a 156494.doc 12-201208843 R〇M (read only memory) that stores the program. And expand the RAM (randomaCCessmem〇ry, random access memory) of the above program. The memory unit 14 stores the distance between the dial amount _ measured by the dial gauge 12 and the cut-off port 20. Wherever: In the case where the displacement sensor is used instead of the dial gauge, the memory unit 14 stores the distance information of the displacement sensor and the cutting table 2〇. Fig. 6 is a block diagram showing the control unit 13 and the like. As shown in Fig. 6, the control is interlocked with the dial gauge 12. Therefore, the control unit 13# can control the linear unit 3 and the tool unit guide rail $ based on the distance information of the dial gauge 12. However, by including the memory unit 14, the distance information can be memorized. Thereby, the cutting of the laminated body film can be performed based on the obtained distance information, and the frequency of obtaining the distance information can be reduced. The cutting of the laminated body film is such that after the distance information is stored in the memory unit 14 by the dial gauge 12, the cutting device 1 is placed again at the initial position of the distance information, and the control unit 13 is used based on the distance information stored in advance. One side of the linear unit 3 is controlled. Thereafter, the distance information is obtained when the position of the cutting table 20 is changed. In other words, it is sufficient to perform the initial setting of the cutting table 2 and the position change. Further, although not shown, the control unit 13 also slides the linear motor that moves the main base 2, and controls the linear unit 70 3 in consideration of the moving speed of the linear motor sliding portion. Further, the control unit 13 is also coupled to the cutter unit guide rail 9 or the cutter unit LM guide 9. As the storage unit 14, for example, a magnetic tape such as a magnetic tape or a cassette tape, a disk such as a flexible (registered trademark) disk/hard disk, or a CD_156494.doc •13·201208843 ROM (compact disc read only memory) can be used.

As described above, according to the present invention, during the period in which the cutting device i is moved by the linear motor sliding portion, the linear unit 3 can be controlled by the control unit 13 so that the cutter unit 7 cuts the cutting direction of the circular blade and the cutting table. 2 〇 parallel. Further, the position of the cutting blade is adjusted by the linear unit 3. In the cutting device 1, the linear motor sliding portion is moved along the cutting table 2, and the cutting device is moved in a state in which the laminated body film is disposed. Therefore, a part of the film in the laminated body film can be cut. Therefore, the half cut can be performed in a state where the cutting edge of the cutting blade and the cutting table are kept in parallel. The specific embodiments and examples of the present invention are intended to be illustrative of the technical scope of the present invention, but are not limited to such specific examples and are interpreted in a narrow sense, which may be in the spirit of the present invention and the following It is implemented in various changes within the scope of the patent application described. Further, the cutting device of the present invention includes the following aspects. Preferably, the cutting device of the present invention further includes a memory unit for storing the distance information control of the distance 156494.doc 14 201208843, wherein the control unit cuts the blade adjusting unit based on the memory unit. Therefore, the laminated body film can be formed in the laminated body film, and once the distance information is obtained, the cutting is performed, and the frequency of obtaining the distance information can be reduced. Preferably, a part of the cutting device of the present invention is used. The film is a polarizing film. Usually, the polarizing film is conveyed by a long strip. In the process of transporting, the polarizing film must be sequentially cut, so that the polarizing film is a preferable object to be cut. In order to solve the problem, the method for cutting a laminated film of the present invention is to cut off a part of the laminated film having a plurality of laminated films by using the laminated film of the laminated film of the present invention. The cutting method adjusts the position of the cutting blade according to the distance information of the dial gauge or the displacement sensor and the cutting table measured by the dial gauge or the displacement sensor, so as to be relative to the laminated layer. The cutting direction of the cutting blade of the body film is parallel to the cutting table, and the cutting blade is moved along the cutting table that supports the laminated body film, thereby cutting a part of the film in the laminated body film. According to the above invention, by using the dial gauge or the displacement sensor, the cutter can be adjusted according to the dial gauge measured by the dial gauge or the displacement sensor or the distance information of the displacement sensor and the cutting table. The position is such that the cutting direction of the cutting blade is parallel to the cutting table. This cutting device does not control the position of the cutting blade based on the information on the laminated body film based on the information on the laminated body film, so that the cutting edge of the cutting blade and the cutting table can be kept more parallel.
