When the liquid crystal display element is continuously produced by incomplete elimination of defective sheet X _beta, production yield is naturally deteriorated. The only way to avoid sacrificing the production volume per hour is to dispose of the defective product. Further, in order to improve the yield, the defective sheet _Xβ is peeled off by reworking the manufactured defective product, and if the rectangular panel W is to be reused by this, the reworking work following the continuous manufacturing process of the liquid crystal display element is performed. The process is an essential process. Therefore, in the continuous production of the liquid crystal display element, the normal sheet _Xα and the rectangular panel W are provided, for example, by providing a dummy sheet conveyance path shown in Patent Documents 1 and 2, that is, a defective sheet removal apparatus 190 including a defective sheet discharge path 193. before reaching the final step of bonding the bets, the elimination station C, step for keeping reliably eliminate defective sheet X _beta of the polarizing film sheets X will be asked.

An incomplete separation of normal sheet X _alpha, normal sheet X _alpha is inverted on the carrier film Z integrally toward the carrier film collecting path 170, the wound is a situation that must be free.

The carrier film Z protects the adhesive layer of the polarizing film Y during the process of continuously producing liquid crystal display elements, and the polarizing film sheet X (that is, normal) including the adhesive layer before or when being bonded to the rectangular panel W. The release film is wound up and collected when the sheet X _α and the defective sheet X _β ) are peeled from the strip-shaped film laminate 2. The tip of the normal sheet X _alpha polarizing film sheet X containing an adhesive layer formed on the belt-shaped film laminate 2 of the carrier film on the Z is at bonding positions of the rectangular panel W, synchronized with the feed of normal sheets X _alpha The normal sheet _Xα is reliably peeled off from the carrier film Z by bending and winding only the carrier film Z through the peeling plate 150 having a wedge-shaped cross section at a position reaching the front end of the rectangular panel W fed in be able to. Therefore, the normal sheet _Xα and the rectangular panel W are aligned, and their bonding operation is started. On the other hand, when the defective sheet X _beta has reached the end point (i.e., elimination starting point) of the transport path of the film web laminate 2, to separate the pair of lamination rollers 121 and 122 constituting the lamination drive 12, bonded The combined drive device 12 is deactivated, and the moving roller 192 constituting the defective sheet discharge path 193 is moved to the gap between the separated bonding rollers while the moving roller 192 is replaced with one bonding roller 122. By doing so, the moving roller 192 and the other bonding roller 121 are interlocked. By them, the defective sheet X _beta which is reliably separated from the normal sheet X _alpha as well as the carrier film Z, is through the defective sheet discharge path 193 can be reliably removed from the film strip stack 2.

In the field of manufacturing liquid crystal display elements, productivity per hour is constantly increased, and downsizing and labor saving of the entire apparatus are required.

The determination device 3 that operates in conjunction with the feeding of the belt-shaped film laminate 2 determines whether the polarizing film sheet X including the adhesive layer formed on the carrier film Z is a normal sheet _Xα or a defective sheet _Xβ. judge. When the polarizing film sheet X on the carrier film Z that is sent is a defective sheet _Xβ , it is in contact with the surface of the belt-shaped film laminate 2 on the conveyance path 110 between a pair of guide rollers 151 and 152 that are rotatably supported. The carrier film Z collected by the carrier film take-up driving device 17 is bent at an acute angle by cooperation with both guide rollers 151 and 152 via the peeling means 15 comprising the peeling plate 150 having a wedge-shaped cross section disposed. Has been.

3 (a) it is also representative of the state in a position in which the top portion of the release plate 150 in contact with the back surface of the carrier film Z corresponds to the tip portion of the defective sheet X _beta on the carrier film Z. At this time, as apparent from FIG. 4, the film supply devices 4, 9, 11, 13 and the carrier film take-up drive device 17 are in a stopped state, and the laminating drive device 12 is in an inoperative state once stopped. And it is just before a gap | interval is formed between a pair of bonding rollers 121 and 122 which comprise the bonding drive device 12. The defective sheet path configuration driving device 16 that operates when the bonding driving device 12 is inactive includes a moving roller 161 for supporting the recovered carrier film Z without loosening in conjunction with the tension adjusting device 14. At this time, the moving roller 161 is just before being lifted along the guide rail 162.

FIG. 3 (b) represents the timing at which the discharge preparation of defective sheet X _beta is complete. It also represents just before the rewinding of the carrier film Z is resumed. Based on the command of the control device 300, the defective sheet path configuration driving device 16 is operated, and at the same time, the upper bonding roll 121 and / or the lower bonding roll 122 of the bonding driving device 12 is moved to the upper guide rail 124 and / or. It raises and / or descends along the lower guide rail 123 to form a gap between the pair of bonding rollers 121 and 122. Due to the operation of the defective sheet path configuration driving device 16, the moving roller 161 is moved along the guide rail 162 and replaced with the lower laminating roller 122 lowered along the lower guide rail 123 of the laminating driving device 12. Then, the upper bonding roller 121 can be interlocked. At this time, the film supply devices 4, 9, 11, 13 and the carrier film take-up driving device 17 are stopped, the moving roller driving device 163 is interlocked with the tension adjusting device 14, and the moving roller 161 is along the guide rail 162. Move to. As it is apparent from the flow diagram of FIG. 2, at a timing when the leading end portion of the defective sheet X _beta reaches the top of the peeling plate 150, in accordance with an instruction of the control unit 300, a film feeder 4,9,11,13 and The carrier film winding drive device 17 is stopped. By making the movable roller 161 and the upper laminating roller 121 interlockable before the film supply devices 4, 9, 11, 13 and the carrier film winding drive device 17 are restarted, preparation for discharging the defective sheet X _β is performed. Is made.

Figure 3 (c) represents the operation of the defective sheet X _beta discharged after re sticking to the recovery path 170 of the carrier film Z. Rewinding of the film supply devices 4, 9, 11, 13 and the carrier film winding drive device 17 starts the winding of the carrier film Z. Defective sheet X _beta, as described later, it is peeled off through the peeling plate 150 by the winding of the carrier film Z, it is through the defective sheet discharge path 160 formed by the moving roller 161 and the upper bonding roller 121 Thus, the sheet is fed so as to penetrate between the conveying rollers constituting the rectangular panel conveying device 204. It is also affixed again to a part of the collection path 170 of the carrier film Z that is sent so as to bypass the back surface of the rectangular panel transport device 204, and is wound up integrally with the carrier film Z and discharged. The collection path 170 for the carrier film Z can be configured using, for example, the following detour structure that does not pass between the conveyance rollers that constitute the rectangular panel conveyance device 204.

      Please refer to FIG. The carrier film Z from which the polarizing film sheet X has been peeled is fed so as to travel parallel to the upper surface of the rectangular panel transport device 204 via a guide roller, for example. For example, the carrier film bending unit 18 is disposed so as to cross the back surface composed of the conveyance rollers of the rectangular panel conveyance device 204 having a certain width. The carrier film bending unit 18 includes an air turn bar 181 and a guide roller 182. They are positioned so as to protrude on both sides of the rectangular panel transport device 204 so as to reverse the carrier film Z to be fed and bypass the rectangular panel transport device 204. The carrier film bending unit 18 is a device that bypasses the carrier film Z so as to avoid the space between the conveyance rollers of the rectangular panel conveyance device 204. By using this, the carrier film Z can be sent so as to run in parallel with the back surface of the rectangular panel transport device 204. As a result, a recovery path 170 for the carrier film Z supported by the moving roller via the tension adjusting device 14 is formed. It is also configured to be continuous with the defective sheet discharge path 160. This is a case where the rectangular panel transport device 204 is composed of transport rollers arranged in a straight line. When the rectangular panel transport device 204 is configured in a plane L shape or Z shape, the recovery path 170 of the carrier film Z is sent to the back surface of the rectangular panel transport device 204 without using the detour structure as described above. Needless to say, the vehicle can run in parallel with the vehicle.

In FIG. 3 (c), the film supply devices 4, 9, 11, 13 and the carrier film take-up drive device 17 are restarted, as is apparent from the arrows. By the peeling operation of the defective sheet X _beta is started via the peeling plate 150. Peeled defective sheet X _beta is sent to the formed gap between the pair of lamination rollers freed defective sheet discharge path 160, a portion of the recovery path 170 of the supported carrier film Z to move roller 161 The transfer roller 161 and the upper bonding roller 121 which are pasted again and replaced with the lower bonding roller 122 are pressure-bonded and conveyed. At that time, the tension adjusting device 14 functions as a guide roller without operating. Further, the moving roller 161 is operated to rotate by the moving roller driving device 163. Thus by the length of the defective sheet X _beta is crimped conveyed.

Next, only the film supply devices 4, 9, 11, and 13 are stopped. The moving roller driving device 163 and the carrier film take-up driving device 17 are further operated and interlocked with the tension adjusting device 14 that absorbs the collected carrier film Z without loosening, and continues the discharging operation of the defective sheet _Xβ . That is, the discharge amount is set to be equal to or longer than the predetermined length of the defective sheet _Xβ . If the polarizing film sheets X followed defective sheet X _beta is defective sheet X _beta the same operation is repeated. In the case the polarizing film sheet X followed defective sheet X _beta is normal sheet X _alpha is film supply apparatus 4,9,11,13 and the carrier film take up drive mechanism 17 is stopped again. The moving roller driving device 163 is also stopped. Next, a preparation operation for returning the bonding drive device 12 shown in FIG.

3 (d) is a schematic diagram polarizing film sheets X on the carrier film Z is assume that the switches normally sheets X _alpha from defective sheet X _beta. It represents a preparation operation for returning the bonding drive device 12. Band determining unit 3 which operates in conjunction with feeding of the film laminate 2 has already determined that the polarizing film sheet X with the following adhesive layer formed on transmitted carrier film Z is normal sheet X _alpha is doing. The top of the peeling plate 150 in contact with the back surface of the carrier film Z is in the position corresponding to the tip portion of the normal sheet X _alpha on the carrier film Z.

Moreover, the bonding drive device 12 is only the film supply devices 4, 9, 11, and 13 in an inoperative state in which a gap is formed between the pair of bonding rollers 121 and 122 constituting the bonding drive device 12. First, the carrier film winding drive unit 17 is also stopped. Therefore, the strip | belt-shaped film laminated body 2 is not sent. By the way, as the carrier film take-up driving device 17 is stopped, the moving roller 161 for supporting the carrier film Z recovered in conjunction with the tension adjusting device 14 without loosening in conjunction with the tension adjusting device 14 is defective. The sheet path configuration driving device 16 is operated so as to move from the defective sheet discharge path 160 configured by the upper bonding roller 121 along the guide rail 162 and return to the original position. At that time, the carrier film Z is slackened as the moving roller 161 returns to the original position. This loosening is absorbed by the tension adjusting device 14. By the defective sheet X _beta that is re-attached to a carrier film Z is somewhat returned. However, before because you to be carried out to more defective sheet X _beta length in step, there is no possibility that malfunction unnecessary peeling occurs. In addition, loosening of the carrier film Z accompanying the return | restoration to the original position of the moving roller 161 can also be absorbed by reversely rotating the carrier film winding drive device 17 without using the tension adjusting device 14. Next, the bonding drive device 12 is restarted. As a result, the lower bonding roller 122 that has been lowered rises along the lower guide rail 123, and the normal sheet bonding path 120 is configured with the upper bonding roller 121. That is, the bonding drive device 12 is operated, and the pair of bonding rollers 121 and 122 can be interlocked again.

FIG. 3 (e) is a schematic diagram assuming that the film supply devices 4, 9, 11, 13 and the carrier film take-up drive device 17 are restarted, as is apparent from the arrows. Re-operation of the film feeding device 4,9,11,13 and the carrier film take up drive mechanism 17, the peeling operation of the normal sheet X _alpha is resumed via the peeling plate 150. Normal Sheet X _alpha peeled, by the operation of the lamination drive 12, by way of the normal sheet bonding path 120, the rectangular panel W to be sequentially transmitted to the bonding position in synchronization with the feed of normal sheet X _alpha, Bonding is carried out so as to convey by pressure. At that time, defective sheet X _beta stuck again on a part of the recovery path of the carrier film Z 170 is the carrier film take up drive mechanism 17, is wound on the carrier film Z integrally. In the case where a polarizing film sheet X subsequent thereto is determined to be normal sheets X _alpha, bonding operation of a rectangular panel W is continuously repeated. When the polarizing film sheet X is determined to be the defective sheet _Xβ , the process returns to the step shown in FIG.

(Timing of each manufacturing process based on the flow diagram)
Please refer to FIG. Steps 1 to 3 are based on the defect positions inherent in the polarizing film Y of the strip-shaped film laminate 2 calculated by the calculation of the information processing device 301 of the control device 300, as is apparent from the operation steps shown in the flowchart. Using the determination device 3 of the determination station A, the polarizing film sheet X to be formed on the carrier film Z between the cut line in the width direction on the downstream side and the upstream side in the feeding direction is the normal sheet X which of _α or defective sheet X _beta, it determines. In step 2, a cutting line is formed on the carrier film Z at the cutting station B, and the cutting line position of the formed polarizing film sheet X is stored in the storage device 301 of the control device 300.

When step 3 is determined to be a normal sheet X _α , the film supply devices 4, 9, 11, 13 and the carrier film take-up driving device 17 are operated by steps 10 to 12, and the normal sheet X _α from the carrier film Z is The peeling operation is started. At the same time or prior to that, the bonding drive device 12 is operated from step 14 to step 15, and the rectangular panel unloading device 204 is operated so as to send out the rectangular panel W from the rectangular panel magazine 201 in conjunction with it. Rectangular panel W is pre-aligned is performed, is a position correction so as to be aligned in the normal sheet X _alpha. Further, in step 13 and step 16, the normal sheet _Xα and the rectangular panel W are pressure-bonded and conveyed by the pair of driven bonding rollers 121 and 122. That is, the bonding operation of the normal sheet X _alpha and the rectangular panel W is started. Thus, the liquid crystal display element manufactured continuously is conveyed by step 17 to the final inspection process.

Step 3 is determined to be defective sheet X _beta, in step 4, based on the command of the control unit 300 temporarily stops the pair of bonding rollers 121 and 122 to be driven lamination drive device 12, lamination drive 12 Becomes inoperable. Next, a pair of bonding rollers 121 and 122, in the vertical direction with respect to the rectangular panel W or feed normal sheet X _alpha, for example, while increasing along the upper lamination roll 121 to the upper guide rail 124, the lower It is released by lowering the side bonding roll 122 along the lower guide rail 123. Thereafter, the bonding drive device 12 is completely stopped. At the same time or prior thereto, the operation of the defective sheet path forming drive device 16 including the tension adjusting device 14 is started, and the moving roll 161 that supports the carrier film Z in the gap between the released pair of bonding rolls 121 and 122. The defective sheet discharge path 160 is configured to be continuous with the collection path 170 of the carrier film Z in conjunction with the upper bonding roll 121 by moving the lower bonding roll 122. In step 5, the defective sheet X _β once peeled from the carrier film Z is conveyed under pressure by the upper laminating roll 121 and the moving roll 161. As a result, the defective sheet _Xβ is attached to the carrier film Z again. In step 6, the film supply devices 4, 9, 11, and 13 are deactivated. In step 7, further actuated carrier film take up drive mechanism 17, re-affixed evacuation operation of the defective sheet X _beta is further continued to the carrier film Z.

FIG. 4 is a timing chart of each manufacturing process. It shows the operation means and device in the vertical column, and the respective operating states in the horizontal column. Longitudinal column, first, showing a positional relationship between the tip / rear end and the release plate 150 of the defective sheet X _beta. Next, the bonding drive device 12, the film supply devices 4, 9, 11, 13, the upper bonding roller 121 (up / down signal), the lower bonding roller 122 (up / down signal), the moving roller 161 (forward) / Retraction signal), defective sheet path forming drive device 16, tension adjusting device 14, carrier film winding drive device 17 and the like. Yokoran is, ON lamination drive 12 (bonding) / OFF (released), ON / OFF of the film feeding device 4,9,11,13, discharge preparation of defective sheet X _beta, the length of the defective sheet X _beta is equivalent discharge operation, the discharge operation of the above lengths of the defective sheet X _beta, up / down signal of the upper lamination rollers 121, down / up signal of the lower laminating roller 122, forward / reverse signal of the mobile roller 161, It represents ON / OFF of the defective sheet path forming drive device 16, ON / OFF of the tension adjusting device 14, and ON / OFF of the carrier film winding drive device 17. Thereby, the mutual relationship of each manufacturing process shown in the flowchart of FIG. 2 and the schematic diagram of FIG. 3 will become clearer.

      FIG. 6 relates to a second embodiment of the present invention. As apparent from FIGS. 8A to 8E, the difference in configuration from the first embodiment is that the carrier film Z can be used without using the carrier film bending unit 18 including the air turn bar 181 and the guide roller 182. The recovery path 170 is made to coincide with the defective sheet discharge path 160, and further, the recovery path 170 of the carrier film Z is parallel to the upper surface of the rectangular panel transport device 204 without detouring to the back surface of the rectangular panel transport device 204. It is configured that the carrier film Z is sent so as to travel.

In summary the operation represented in FIG. 8 (a) ~ (e) , 8 (a) is the tip of the defective sheet X _beta on the top carrier film Z of the release plate 150 in contact with the back surface of the carrier film Z It represents the state at the corresponding position. At this time, based on the instruction | command of the control apparatus 300, the film supply apparatuses 4, 9, 11, 13 and the carrier film winding drive apparatus 17 will be in a stop state, and a pair of bonding roller by which the bonding drive apparatus 12 is driven 121 and 122 are temporarily stopped. That is, it is just before a gap is formed between the pair of bonding rollers 121 and 122 constituting the bonding driving device 12.

FIG. 8 (b) represents the timing at which the discharge preparation of defective sheet X _beta is complete. It also represents just before the rewinding of the carrier film Z is resumed. Based on the command of the control unit 300, and at the same time actuating the defective sheet path forming drive unit 16, a pair of bonding rollers 121 and 122, in the vertical direction with respect to the rectangular panel W or feed normal sheet X _alpha, for example, The upper laminating roller 121 moves upward along the upper guide rail 124, and the lower laminating roll 122 descends along the lower guide rail 123, thereby being released, and a pair of laminating A gap is formed between the rollers 121 and 122. Next, when the defective sheet path configuration driving device 16 is operated, the moving roller 161 moves along the guide rail 162, replaces the lower laminating roller 122, and moves down along the upper guide rail 124. It becomes possible to interlock with the laminating roller 121. At this time, the moving roller 161 stops the film supply devices 4, 9, 11, 13 and the carrier film take-up driving device 17, and moves the moving roller driving device 163 along with the tension adjusting device 14 so as to follow the guide rail 162. Move to. As it is apparent from the flow diagram of FIG. 7, at the timing when the leading end portion of the defective sheet X _beta reaches the top of the peeling plate 150, in accordance with an instruction of the control unit 300, a film feeder 4,9,11,13 and The carrier film winding drive device 17 is stopped. By making the movable roller 161 and the upper laminating roller 121 interlockable before the film supply devices 4, 9, 11, 13 and the carrier film winding drive device 17 are restarted, preparation for discharging the defective sheet X _β is performed. Is made. FIG. 8B also shows a state in which the bonding drive device 12 is completely stopped and the bonding drive device 12 is inoperative at that stage.

Please refer to FIG. In step 5, the defective sheet X _β once peeled from the carrier film Z is pasted again on a part of the recovery path 170 of the carrier film Z via the defective sheet discharge path 160 formed in step 4. Further, the moving roller 161 is operated to rotate by the moving roller driving device 163. Thus, the carrier film Z re stuck defective sheet X _beta is crimped conveyed by the length of the defective sheet X _beta. FIG. 8C illustrates this. Therefore, unlike the first embodiment, the present embodiment does not use the carrier film bending unit 18, and further bypasses the collection path 170 of the carrier film Z to the back surface of the rectangular panel transport device 204 without using the rectangular panel. The carrier film Z can be fed so as to run parallel to the upper surface of the transport device 204. Therefore, the recovery path 170 of the carrier film Z re stuck defective sheet X _beta, it means that is bent at an acute angle immediately after re-application of the defective sheet X _beta, so as not to trouble such as removability occurs, The moving roller 161 and the laminating roller 121 are interlocked and conveyed by pressure. As a result, the defective sheet _Xβ becomes part of the collection path 170 of the carrier film Z configured to be continuous with the defective sheet discharge path 160, as in the case of FIG. 3C of the first embodiment. It is affixed again and discharged together with the carrier film Z.

FIG. 7 to FIG. 9 are flowcharts showing respective manufacturing steps therefor, schematic diagrams showing processing steps (a) to (e) of the normal sheet X _α and the defective sheet X _{β in} the discharge station C and the bonding station D, It is a timing chart showing the operation of each component. They correspond to FIGS. 2 to 4 of the first embodiment.

The feature of the present invention is that the defective sheet _Xβ and the carrier film Z, which have been processed by two different paths so far, are processed integrally. As a method of processing integrally with the recovered carrier film Z, a method of processing the defective sheet _Xβ integrally with the carrier film Z without peeling the defective sheet _Xβ from the carrier film Z is assumed. However, that case, some Kamada normal sheet X _alpha or defective sheet X _beta, releasing the release means 15 is brought into contact with the back surface of the carrier film Z, or to start the peeling operation, the back surface of the carrier film Z A non-peeling action to release means 15 must be started. For this reason, the peeling means 15 must adopt a switchable structure including the application timing of the peeling / non-peeling operation. Not only that, the peel force can be reliably peeled off only normal sheet X _alpha from the carrier film Z is, such as adjusting to exceed the adhesive force between the adhesive layer of the carrier film Z and the polarizing film sheet X, to overcome technical There are many challenges.

As seen above, the present inventors have found that by controlling the whole to work each of the means or device, based on the same etching conditions, peeling the defective sheet X _beta not normal sheet X _alpha only , Thereafter, the peeled normal sheet X _alpha, while bonding so as to crimp conveyed rectangular panels W by way of the normal sheet bonding path 120, the peeled defective sheet X _beta, defective sheet discharge path 160 The method and the apparatus that can be pasted again to a part of the collection path 170 of the carrier film Z and processed integrally with the carrier film Z are realized. This has greatly simplified and streamlined previous methods and apparatus.
