The description will be made assuming that the pasting operation is performed. In FIG. 1, the table 20 has shown the case where it came to the state which moved to the position which performs the operation | movement which affixes the polarizing film 30 on the glass substrate 10. FIG.

  The film member supply mechanism unit 100 includes a peeling roll 110 that peels the release film 40 from the polarizing film 30 by folding the release film 40 in a direction substantially opposite to the direction in which the polarizing film 30 travels, and a release that is folded back by the peeling roll 110. A release film advancing mechanism 120 for advancing the film 40, a guide member 130 having a guide surface 131 for guiding the progression of the polarizing film 30 from which the release film 40 has been peeled off by the peeling roll 110, and a leading end portion in the advancing direction of the polarizing film 30 When 30a (hereinafter abbreviated as the front end portion 30a) reaches the application start end 10a of the glass substrate 10, a pressing roll that presses the front end portion 30a of the polarizing film 30 against the application start end 10a at the application start end 10a. 140 , And a predetermined portion (which will be described later.) Imaging capable camera installed 150 the polarizing film 30, the.

  The peeling roll 110 is a roll having a bearing. Thereby, when peeling the release film 40 from the polarizing film 30, the release film 40 can be smoothly peeled with a small force.

  In addition to the above-described components, the film member supply mechanism unit 100 is provided with rolls 161 and 162 that cause the polarizing film 30 (the polarizing film 30 with the release film 40 attached) to bend and advance. Yes. In addition, there are a delivery mechanism unit that sends out the polarizing film 30 (the polarizing film 30 with the release film 40 attached) and a dancer roll that is provided in the middle of the traveling path. .

  In FIG. 1, the polarizing film 30 (the polarizing film 30 with the release film 40 attached) is bent downward at a large angle by the roll 161, and then is made to the xy plane by the roll 162. Then, it is bent to reach a predetermined angle (30 degrees in the film member attaching apparatus 1 according to the first embodiment) and reaches the peeling roll 110. As described above, the polarizing film 30 (the polarizing film 30 with the release film 40 attached) is bent or slanted in the traveling direction downward by the rolls 161 and 162 on the traveling path of the polarizing film 30. However, it is assumed that the traveling direction of the polarizing film 30 is generally a direction from the right to the left in the drawing along the x axis (arrow x ′ direction). Therefore, in this specification, when the traveling direction of the polarizing film 30 is described, it is expressed as “arrow x ′ direction along the x axis” or “right to left direction in the drawing”.

  FIG. 2 is a view for explaining the polarizing film 30. FIG. 2A is a plan view of the polarizing film 30, and FIG. 2B is a cross-sectional view of the polarizing film 30. As shown in FIG. 2, the polarizing film 30 has a long shape, and a long release film 40 is attached to the polarizing film body 32 through the adhesive layer 34 so as to be peeled off. The polarizing film 30 is provided with a cut for each predetermined length, leaving the release film 40 so that the polarizing film 30 can be separated into pieces corresponding to the individual glass substrates 10 (see FIG. 1) to be attached. ing. For example, in the case where the long side (1500 mm) of the glass substrate 10 is placed on the table 20 along the x axis, the release film is provided for each long side (1490 mm) of the polarizing film 30. The cuts C1, C2,...

  In addition, in the elongate polarizing film 30 shown in FIG. 2, when each polarizing film corresponding to each glass substrate is demonstrated separately, each polarizing film is first polarizing film in order from the left side in FIG. 30, the second polarizing film 30, and so on. In addition, in each polarizing film 30, cut | interruption C1, C2, ... may become a rear-end part (following abbreviated as a rear-end part) in the advancing direction, and may become a front-end | tip part. . For example, when paying attention to the first polarizing film 30, the break C1 becomes the rear end portion 30b of the first polarizing film 30, and when paying attention to the second polarizing film 30, the break C1 It becomes the front end portion 30 a of the second polarizing film 30.

  Returning to FIG. 1, individual components of the film member pasting apparatus 1 according to the first embodiment will be described in more detail.

  The table 20 can reciprocate in the direction of the arrow x-x ′ along the x-axis on the guide rail 60 laid on the stage 50. The table 20 can be adjusted not only for reciprocation along the x-axis but also for position adjustment along the y-axis and angle adjustment on the xy plane. The control for reciprocating the table 20 along the x-axis, adjusting the position along the y-axis, and adjusting the angle on the xy plane can be performed as one of the control functions of the control device 200. . Moreover, in the film member sticking apparatus 1 which concerns on Embodiment 1, the table 20, the stage 50, and the guide rail 60 shall consist of metals, such as iron, for example.

  The release film advancing mechanism unit 120 has a function of advancing the release film 40 folded by the peeling roll 110 in the arrow x direction. In addition, let the advancing direction (arrow x direction) of the release film 40 folded by the peeling roll 110 be a “release film advancing direction”.

  The release film advancing mechanism unit 120 includes a dancer roll 125 installed on the downstream side in the advancing direction of the release film 40 folded by the peeling roll 110, a plurality of rolls (for example, rolls 121 to 124), a peeling roll 110, A feeder mechanism 126 provided between the dancer rolls 125 (specifically, between the rolls 122 and 123) and a further downstream side of the dancer rolls 125 to wind the release film 40 For example, a take-up roll (not shown) is provided.

  The feeder mechanism part 126 has a plurality of clampers 127 for clamping the release film 40, and can reciprocate in the direction of the arrow x-x 'along the x-axis. The feeder mechanism portion 126 has a function for causing the leading end portion 30a of the polarizing film 30 from which the release film 40 has been peeled to reach the attaching start end 10a of the glass substrate 10.

  Such an operation of the feeder mechanism 126 is performed as one of the control functions of the control device 200. In this case, the control device 200 monitors the position (position along the x axis) of a predetermined portion (for example, the rear end portion 30b) of the polarizing film 30 based on the photographing data from the camera 150, and the leading end of the polarizing film 30 The feeder mechanism 126 is controlled so that the part 30a reaches the sticking start end 10a of the glass substrate 10.

  As an example of control with respect to the feeder mechanism part 126 by the control apparatus 200, for example, the control apparatus 200 is based on the photographing data from the camera 150, and the polarizing film (first polarizing film 30 and the first polarizing film 30) to be pasted at the present time. The position of the rear end 30b (the cut C1 between the first polarizing film 30 and the second polarizing film 30) is monitored, and the position of the rear end 30b (cut C1) reaches the target position. Until then, the feeder mechanism 126 is operated.

  Specifically, the position of the rear end portion 30b of the polarizing film 30 when the front end portion 30a of the polarizing film 30 has correctly reached the pasting start end 10a of the glass substrate 10 is obtained in advance as a “target position”. The control device 200 advances the release film 40 in the release film advancing direction until the position of the rear end portion 30b (cut C1) of the first polarizing film 30 to be attached at the current time reaches the target position. Thereby, the front-end | tip part 30a of the said 1st polarizing film 30 can be made to arrive at the sticking start end 10a of the glass substrate 10 accurately.

  And when the position of the rear-end part 30b (cut C1) of the polarizing film 30 reaches | attains a target position, the clamp operation | movement of the release film 40 is cancelled | released and it controls to return the feeder mechanism part 126 to the original position.

  Note that the camera 150 monitors the position of the rear end portion 30b (cut C1) of the first polarizing film 30 to be pasted at the present time in the film member pasting apparatus 1 according to the first embodiment. However, if the camera 150 tries to monitor the position of the front-end | tip part 30a of the 1st polarizing film 30 which is a sticking object at the present time, presence of the pressing roll 140 (refer FIG. 1). This is because there is no room for installing the camera 150. However, if there is enough space for installing the camera 150, the position of the front end portion 30a of the first polarizing film 30 to be pasted at the present time may be monitored.

Next, the guide member 130 and the pressing roll 140 will be described with reference to FIG.
FIG. 3 is a view for explaining the guide member 130 and the pressing roll 140. FIG. 3A is an enlarged view of the press roll 140 of FIG. 1 and the range surrounded by the broken line frame A in FIG. 1, and FIG. 3B is a diagram along FIG. 3A along the z axis. It is the figure (plan view) seen from the top. In addition, in FIG.3 (b), illustration of the pressing roll 140 shown by Fig.3 (a) is abbreviate | omitted.

  First, the guide member 130 will be described. The guide member 130 serves to guide the progress of the polarizing film 30 from which the release film 40 has been peeled off. 3 is also a schematic diagram similar to FIG. 1, and the mounting structure of the guide member 130 is not shown. However, the guide member 130 is a support member (see FIG. (Not shown). The support member is also made of a metal such as iron. Further, the guide member 130 is made of, for example, a metal such as stainless steel, and the guide surface 131 (surface on the side in contact with the polarizing film 30) of the guide member 130 is non-tacky to prevent adhesion of an adhesive. Surface treatment is given. This is because one surface of the polarizing film 30 is an adhesive surface having adhesiveness.

  That is, the release film 40 is detachably attached to the adhesive surface of the polarizing film 30, and one surface of the polarizing film 30 in a state where the release film 40 is peeled (the surface on the side where the release film 40 is attached). ) Has adhesiveness, so that the adhesive surface of the polarizing film 30 does not adhere to the guide member 130 unless the non-sticky surface treatment for preventing the adhesion of the adhesive is applied to the guide surface 131 of the guide member 130. This is because it adheres to the guide surface 131 and the polarizing film 30 cannot proceed smoothly along the guide surface 131 of the guide member 130.

  The non-tacky surface processing for preventing the adhesion of the adhesive is a known technology, and for example, a surface processing technology called “Tocical S (registered trademark) coating processing” can be adopted. By applying such surface processing (coating film formation processing of TOSICAL (registered trademark) S / Toshiko Co., Ltd.) to the guide surface 131 of the guide member 130, the adhesive surface of the polarizing film 30 from which the release film 40 has been peeled is guided. Without adhering to the guide surface 131 of the member 130, the polarizing film 30 can be smoothly advanced to advance to the attachment start end 10a of the glass substrate 10. For example, UNA-300 series (UNA-310-X10), UNA-800 series, TS-1000 series, TS-1080 series, TS-1310 series are preferably used as the TOSICAL (registered trademark) S. it can.

  The film thickness of the coating film of TOSICAL (registered trademark) S is, for example, 1 μm to 200 μm, preferably 3 μm to 150 μm. Before forming the coating film of TOSICAL (registered trademark) S, an uneven structure may be formed on the guide surface 131 of the guide member 130. In this case, the average surface roughness Ra of the concavo-convex structure can preferably be 2 μm to 15 μm.

  In addition, the guide member 130 has a leading end 132 of the guide member 130 as an edge, and the guide surface 131 has an acute inclination with respect to the glass substrate 10. Specifically, in the film member bonding apparatus 1 according to the first embodiment, the guide member 130 has a triangular block shape, and the distal end portion 132 forms an acute angle.

  As shown in FIG. 3A, the guide member 130 configured in this way has a position on the vertical line L (the pasting operation) where the pasting start end 10 a of the glass substrate 10 passes through the pressing point P of the presser roll 140. When reaching the starting position), the glass substrate 10 is installed so that the sticking start end 10a is positioned on the extension of the guide surface 131. In addition, the guide member 130 has a height (position along the z axis) that does not contact the glass substrate 10 placed on the table 20, and a small step between the tip portion 132 and the glass substrate 10. It is installed at such a height. The “pressing point P” of the pressing roll 140 refers to a point that applies a pressing force to the polarizing film 30 when the pressing roll 140 performs an operation of pressing the polarizing film 30.

  Here, the inclination angle of the guide surface 131, that is, the angle θ formed between the guide surface 31 and the xy plane (the angle θ formed between the guide surface 131 and the glass substrate 10 placed on the table 20) is described in the first embodiment. In the film member bonding apparatus 1 according to the above, it is assumed that the angle is set to 30 degrees. Note that the angle θ formed between the guide surface 131 and the glass substrate 10 does not need to be strictly 30 degrees, and it is only necessary that the tip portion 30a of the polarizing film 30 can smoothly reach the attaching start end 10a of the glass substrate 10.

  Further, the distance d (the distance along the x axis) d between the tip end portion 132 of the guide member 130 and the attachment start end 10a of the glass substrate 10 when the attachment start end 10a of the glass substrate 10 reaches the attachment operation start position. The guide member 130 is preferably installed so as to be as narrow as possible. In addition, although the space | interval d changes with inclination angles etc. of the guide surface 131, in the film member sticking apparatus 1 which concerns on Embodiment 1, the space | interval d is 15 mm.

  The guide member 130 is electrically grounded. Specifically, as described above, the guide member 130 is attached to a support member (not shown) standing on the stage 50 (see FIG. 1). Since both are made of metal, the guide member 130 is electrically grounded (grounded) via the support member and the stage 50. Incidentally, the guide surface 131 of the guide member 130 is subjected to the non-adhesive surface processing as described above (for example, surface processing called “Tocical S (registered trademark) coating processing)”. Even if surface processing is performed, the conductivity of the guide surface 131 is not impaired.

  FIG. 1 is a diagram schematically showing the film member pasting apparatus 1 according to the first embodiment, and a specific installation state of the stage 50 is not shown, but the stage 50 is a floor of a factory or the like. It shall be installed in a state where it is electrically grounded. Thereby, the guide member 130 including the guide surface 131 is electrically grounded (grounded) via the support member and the stage 50.

  As described above, since the guide member 130 has the leading end 132 of the guide member 130 as an edge, the gap between the leading end 132 of the guide member 130 and the pasting start end 10a of the glass substrate 10 is possible. While being able to narrow as much as possible, the level | step difference between the front-end | tip part 132 of the guide member 130 and the sticking start end 10a of the glass substrate 10 can be made as small as possible. Thereby, compared with the case where a folding | turning part is made into the folding | turning part which has roundness, for example (refer the broken-line circle B in FIG. 7), until the front-end | tip part 30a of the polarizing film 30 reaches | attains the sticking start end 10a of the glass substrate 10. , And the polarizing film 30 can be prevented from being bent by its own weight until the polarizing film 30 reaches the sticking start end 10a. Thereby, the front-end | tip part 30a of the polarizing film 30 which advances the guide surface 131 can be made to arrive at the sticking start end 10a of the glass substrate 10 accurately. Further, since the guide member 130 is installed so that the sticking start end 10a of the glass substrate 10 is positioned on the extension of the guide surface 131, the leading end portion of the polarizing film 30 that travels on the guide surface 131 is also provided. 30a can be made to reach the attaching start end 10a of the glass substrate 10 with high accuracy.

  Further, since the guide member 130 is electrically grounded (grounded), the static electricity charged on the polarizing film 30 can be removed even when the polarizing film 30 as the film member is charged with static electricity. Since the static electricity charged on the polarizing film 30 can be removed, dust and dust are less likely to adhere to the polarizing film 30, and when the operation of attaching the polarizing film 30 to the glass substrate 10 as a member to be attached is performed, The film member can be attached to the glass substrate 10 with high accuracy. Moreover, when sending the glass substrate 10 with the polarizing film 30 attached thereto to the next step, it is possible to prevent the static electricity from being sent to the next step while being charged.

  Next, the pressing roll 140 will be described. As shown in FIG. 3A, the presser roll 140 has a two-layered structure in which two rolls 141 and 142 having different diameters along the vertical line L, and the respective rotation shafts 141a and 142a are The polarizing film 30 is installed so as to be in the direction along the tip 30a (direction along the y-axis). As for the 1st press roll 141,142, each rotating shaft 141a, 142a is rotatably attached to the press roll attachment member 143. As shown in FIG. Note that the pressing roll attachment member 143 is attached to the film member supply mechanism unit 100.

  Here, of the two pressing rolls 141 and 142, when the pressing roll 141 located on the side in contact with the polarizing film 30 is the first pressing roll 141 and the other pressing roll 142 is the second pressing roll 142, The diameter Φ1 (see FIG. 3A) of the first pressing roll 141 is set smaller than the diameter Φ2 of the second pressing roll 142. In the film member bonding apparatus 1 according to the first embodiment, the diameter Φ1 of the first pressing roll 141 is about 10 mm. As described above, the reason why the first pressing roll 141 and the second pressing roll 142 are configured to be stacked in two steps and the reason why the diameter Φ1 of the first pressing roll 141 is set smaller than the diameter Φ2 of the second pressing roll 142 are described. Will be described later.

  The presser roll 140 (the first presser roll 141 and the second presser roll 142) configured in this way can move up and down in the direction along the z axis (arrow zz ′ direction) together with the presser roll mounting member 143. The plane including the glass substrate 10 placed on the table 20 when the film member bonding apparatus 1 according to the first embodiment is not performing a bonding operation (referred to as a non-bonding operation). When the film member attaching apparatus 1 according to the first embodiment performs the attaching operation (referred to as the attaching operation), it is separated from (the xy plane), and is lowered. The operation of pressing the polarizing film 30 is performed. The raising and lowering operations of the pressing roll 140 are performed as one of the control functions of the control device 200.

  By the way, the diameter Φ1 of the first pressing roll 141 is made smaller than the diameter Φ2 of the second pressing roll 142, and the second pressing roll 142 having a large diameter is stacked on the first pressing roll 141 having a small diameter. The reason is as follows.

  That is, when the glass substrate 10 reaches the attaching operation start position, the distance d between the leading end portion 132 of the guide member 130 and the attaching start end 10a of the glass substrate 10 is 15 mm as described above. In order to prevent the first pressing roll 141 from coming into contact with the guide member 130 when the pressing roll 141 is pressed against the polarizing film 30, it is necessary to make the diameter Φ1 of the first pressing roll 141 as small as possible. There is. On the other hand, when the diameter of the first pressing roll 141 is reduced, the pressing force for pressing the polarizing film 30 is only the first pressing roll 141 in the width direction of the polarizing film 30 (in this case, the width along the y-axis). There is a problem that it may not be applied uniformly over the entire area.

  Specifically, the length of the polarizing film 30 in the width direction (the direction along the y axis in FIG. 3) is about 890 mm in this case. When the length of the polarizing film 30 in the width direction (the direction along the y axis in FIG. 3) is as long as about 890 mm, the length along the rotation axis 141a of the first pressing roll 141 (along the y axis). (Length) also becomes longer. Here, if the diameter Φ1 is small with respect to the length along the rotation axis 141a of the first pressing roll 141, warping may occur. If warping occurs, the pressing force is spread over the entire width direction. Therefore, it will not be uniformly applied. Accordingly, the first pressing roll 141 having a small diameter is provided so that the pressing force by the pressing point P is uniformly applied over the entire width direction of the polarizing film 30 while the diameter Φ1 of the first pressing roll 141 is as small as possible. The second roll 142 having a large diameter is stacked on the top.

  By adopting such a configuration for the presser roll 140, the first presser roll 141 is attached to the guide member 130 even if the distance d between the tip end portion 132 of the guide member 130 and the application start end 10 a of the glass substrate 10 is as narrow as 15 mm. The polarizing film 30 can be surely pressed without contact. Moreover, the 2nd press roll 142 can prevent the curvature of the 1st press roll 141, and can hold down the polarizing film 30 with a uniform pressing force over the whole width direction (y-axis direction). As described above, the second pressing roll 142 functions as a backup roll for backing up the pressing force of the first pressing roll 141.

2. Operation of Film Member Attaching Device 1 According to Embodiment 1 Next, the operation of the film member attaching device according to Embodiment 1 (particularly, the operation of attaching the polarizing film 30) will be described.

  FIG. 4 is a view for explaining the operation of attaching the polarizing film 30 in the film member attaching apparatus 1 according to the first embodiment. FIG. 4A shows a state before starting the pasting operation, and this state is assumed to be this initial state. In this initial state, the table 20 is at a position (start position) on the left side of the figure with respect to the pressing roll 140 (the first pressing roll 141 and the second pressing roll 142). In the initial state, it is assumed that the glass substrate 10 (referred to as the first glass substrate 10) to be attached at this time is placed on the table 20 at a predetermined position on the table 20. . In addition, it is assumed that the amount of movement along the x-axis from the start position of the table 20, the position along the y-axis, the angle around the z-axis (angle on the plane), etc. are adjusted appropriately.

  Further, the release film 40 has a winding-side tip (not shown) connected to a take-up roll (not shown) for winding the release film, and the polarized light to be attached at the present time. It is assumed that the leading end 30a of the film (referred to as the first polarizing film 30) reaches the peeling roll 110. In this initial state, the pressing rolls 140 (the first pressing roll 141 and the second pressing roll 142) are separated from the plane (xy plane) including the glass substrate 10 placed on the table 20 (upward). Is located).

  In the initial state shown in FIG. 4A, first, a step of moving the table 20 is performed. That is, the control device 200 controls the table 20 to advance by a predetermined amount of movement in the right direction (arrow x direction) along the x axis. Thereby, the table 20 moves to the position (pasting operation start position) shown in FIG. Specifically, the control device 200 moves the table 20 in the right direction along the x axis (arrow x) so that the sticking start end 10a of the glass substrate 10 reaches a position facing the pressing point P of the pressing roll 140. Control to proceed in the direction).

  When the table 20 moves to the attaching operation start position shown in FIG. 4B, the leading end portion 30a of the polarizing film 30 from which the release film 40 has been peeled off by the peeling roll 110 reaches the attaching start end 10a of the glass substrate 10. The step of advancing the film member is performed. That is, the control device 200 performs control (film member supply control) for causing the polarizing film 30 to reach the attaching start end 10a of the first glass substrate 10 with respect to the feeder mechanism 126. Thereby, the feeder mechanism part 126 clamps the release film 40 with the clamper 127, and advances the release film 40 by a predetermined amount in the release film advancing direction (illustrated arrow x direction).

  When the release film 40 is advanced by a predetermined amount by the feeder mechanism 126 in the direction of travel of the release film, the release film 40 is peeled off from the first polarizing film 30 by the peeling roll 110 and the release film 40 is peeled off first. The polarizing film 30 travels on the guide surface 131 of the guide member 130, and the leading end 30a of the first polarizing film 30 reaches the sticking start end 10a of the first glass substrate 10 (see FIG. 4B). ).

  At this time, the control of the feeder mechanism unit 126 by the control device 200 is performed based on the captured image data from the camera 150. As an example of the control of the feeder mechanism unit 126 by the control device 200, as described above, the control device 200 is based on the photographing data from the camera 150, and the polarizing film (first polarized light) that is the object to be attached at the present time. The position of the rear end 30b (cut C1) of the film 30) is monitored, and the feeder mechanism 126 is operated until the position of the rear end 30b (cut C1) reaches the target position. Thereby, the front-end | tip part 30a of the 1st polarizing film 30 reaches | attains the sticking start end 10a of the 1st glass substrate 10. FIG. In this way, when the leading end 30a of the first polarizing film 30 reaches the sticking start end 10a of the first glass substrate 10, the control device 200 causes the feeder mechanism 126 to release the clamp of the release film 40. Control. As a result, the feeder mechanism 126 returns to the initial position.

  By the way, when the feeder mechanism part 126 advances the release film 40 in the release film traveling direction, the dancer roll 125 is, for example, as shown in FIG. 4B, the dancer roll at the position indicated by the broken line (FIG. 4A). An operation of lowering the amount corresponding to the movement of the feeder mechanism from the position 125) is performed. By providing such a dancer roll 125, it is not necessary to synchronize the operation of supplying the polarizing film 30 by the feeder mechanism 126 and the operation of winding the release film 40 by a winding roll (not shown). Each operation can be performed independently. Note that the winding operation of the release film 40 by a winding roll (not shown) may be performed when the descending amount of the dancer roll 125 reaches a predetermined amount. When the winding operation of the release film 40 by the winding roll (not shown) is performed, the dancer roll 125 returns to the original position (for example, the position shown in FIG. 4A).

  Here, when the release film 40 advances in the release film traveling direction by the operation of the feeder mechanism portion 126, the release film 40 is folded back by the peeling roll 110 and thus the surface of the release film 40 may be rubbed. Thus, the release film 40 can be prevented from being damaged, and the folded portion (peeling roll 110) can be prevented from being worn away.

  That is, in the film member pasting apparatus 1 according to the first embodiment, the folding portion for peeling the release film 40 from the polarizing film 30 is a roll (peeling roll 110), and the release film 40 is folded by the peeling roll 110 and proceeds. By doing so, the release film 40 is peeled off from the polarizing film 30. For this reason, when performing the operation | movement which peels the release film 40 from the polarizing film 30, while preventing the surface of the release film 40 from rubbing, it can prevent that the release film 40 is damaged, and a return part (peeling roll 110) rubs. It can be prevented from decreasing.

  Further, since the guide surface 131 of the guide member 130 is subjected to non-adhesive surface processing, when the polarizing film 30 from which the release film 40 has been peeled travels along the guide surface 131 of the guide member 130, The polarizing film 30 can be smoothly advanced without the adhesion surface of the polarizing film 30 from which the release film 40 has been peeled off adhering to the guide surface 131 of the guide member 130.

  And when the front-end | tip part 30a of the 1st polarizing film 30 arrives at the sticking start end 10a of the glass substrate 10, so that the front-end | tip part 30a of the polarizing film 30 may be pressed on the sticking start end 10a of the glass substrate 10 with the press roll 140. A step of moving (lowering) the presser roll 140 is performed. Thereby, the press roll 140 (the 1st press roll 141 and the 2nd press roll 142) descend | falls, and the pressing point P of the 1st press roll 141 makes the front-end | tip part 30a of the polarizing film 30 the sticking start edge of the glass substrate 10. It will be in the state pressed down to 10a (refer to Drawing 4 (c)). As a result, the first polarizing film 30 is positioned at the sticking start end 10 a of the first glass substrate 10. At this time, the second pressing roll 142 presses the first pressing roll 141.

  From the state shown in FIG. 4C (the state in which the leading end 30a of the polarizing film 30 is pressed against the sticking start end 10a of the glass substrate 10), the polarizing film 30 is made of glass starting from the sticking start end 10a of the glass substrate 10. A step of moving the table 20 so as to be attached to the substrate 10 is performed. That is, the first polarizing film 30 is attached to the first glass substrate 10 by moving the table 20 in the arrow x ′ direction (the left direction in the figure) along the x axis from the state of FIG. It is pasted starting from the starting edge 10a. At this time, since the pressing roll 140 holds the state in which the first polarizing film 30 is pressed, when the table 20 moves in the direction of the arrow x ′ (the left direction in the drawing), the first pressing roll 141 is turned clockwise. And the second pressing roll 142 presses the first polarizing film 30 against the glass substrate 10 while rotating counterclockwise.

  During the pasting operation as shown in FIG. 4D, a constant tension is always applied to the release film 40 by the dancer roll 125. For this reason, during the operation of attaching the first polarizing film 30, the dancer roll 125 further descends from the position along the broken line in FIG. The film 30 is peeled off. Also in this case, the winding operation of the release film 40 by the winding roll (not shown) may be performed when the descending amount of the dancer roll 125 reaches a predetermined amount.

  By providing such a dancer roll 125, it is not necessary to synchronize the movement operation of the table 20 and the winding operation of the release film 40 by a winding roll (not shown) during the pasting operation. Each operation can be performed independently.

  In addition, when performing such a pasting operation, the release film 40 is folded back by the peeling roll 110 and proceeds, so that the surface of the release film 40 is not rubbed and the release film 40 is damaged. Can be prevented, and the peeling portion (peeling roll 110) can be prevented from being worn away, and the folded portion (peeling roll 110) can be prevented from being worn away.

  Then, when the table 20 further moves in the arrow x ′ direction from the state shown in FIG. 4D, the table 20 returns to the position of FIG. 4A (the same position as the initial state). Thereby, the sticking process of the 1st polarizing film 30 with respect to the 1st glass substrate 10 is complete | finished, Then, the polarizing film (2nd polarizing film 30) with respect to the following glass substrate (it is set as the 2nd glass substrate 10). The pasting process is performed. In order to perform the process of attaching the second polarizing film 30 to the second glass substrate 10, the first glass substrate 10 after the attaching process of the first polarizing film 30 is removed from the table 20, and (2) The glass substrate 10 is placed, and the steps from FIG. 4A to FIG. 4D are performed. By repeating such steps, the polarizing film can be sequentially attached to each glass substrate.

  As shown in FIGS. 1 to 4, the film member pasting apparatus 1 according to the first embodiment has one surface as an adhesive surface, and a release film is pasted to the adhesive surface so as to be peelable. After the release film is peeled from the film member, the film member is moved forward, and after the release film is peeled off, the film material in the direction of travel reaches the starting start point of the attached member, and then the starting start point A film member affixing device for affixing the film member to the affixed member, a peeling device 170 for peeling the release film from the film member, and a forward end portion of the film member from which the release film has been peeled off After reaching the starting start point of the pasting member, the film member is pasted on the pasting member starting from the pasting start end. Affixing device 180, a peeling device 170, and affixing device 180 are disposed between the affixing device 180 and the affixing device 180. The affixing device 180 has a contact surface that is a contact surface with respect to the film member and has conductivity and non-adhesive properties. And a static electricity removing member 190 that is grounded, and the static electricity removing member 190 removes static electricity that may be charged on the adhesive surface of the film member when the release film is peeled off from the film member. It is.

  The film member affixing apparatus 1 according to the first embodiment is configured as “static guide member 131 having a guide surface 131 that guides the progress of the polarizing film 30 and has conductivity and non-adhesiveness” as the static electricity removing member 190. Is provided.

  In the film member bonding apparatus 1 according to the first embodiment, the film member is the polarizing film 30 used for the liquid crystal panel, and the member to be bonded is the glass substrate 10 used for the liquid crystal panel.

  Moreover, the film member affixing method according to the first embodiment is such that one surface is an adhesive surface, and the release film is peeled off from the film member that is releasably attached to the adhesive surface. The film member from which the release film has been peeled off is made to reach the starting start point of the member to be attached, and then the film member is attached to the member as the starting point. A film member pasting method for pasting, a peeling process for peeling a release film from a film member, and a leading end portion in a traveling direction of the film member from which the release film has been peeled is made to reach the sticking start end of a member to be stuck. After that, the pasting process for pasting the film member to the pasting member starting from the pasting start end in this order. In addition, between the peeling step and the attaching step, “static contact member that has a contact surface that is a contact surface to the film member and has conductivity and non-adhesiveness, and is electrically grounded made of metal. , And a static electricity removing step of removing static electricity that may be charged on the adhesive surface of the film member when the release film is peeled from the film member.

  In the method of attaching a film member according to the first embodiment, in the static electricity removing step, the static electricity removing member 190 has “a guide surface that guides the progress of the film member and has conductivity and non-adhesiveness. The guide member 130 "is used to remove static electricity that may be charged on the adhesive surface of the film member.

3. Effects of Film Member Attaching Device, Film Member Adhering Method, and Static Electricity Removing Member According to Embodiment 1 As described above, according to the film member attaching device 1 according to the embodiment 1, the polarizing film 30 to the release film 40 The folding portion for peeling off the film is a roll (peeling roll 110), and the release film 40 is folded and advanced by the peeling roll 110, so that the release film 40 is peeled off from the polarizing film 30. For this reason, “rubbing” does not occur on the surface of the release film 40, and the release film 40 is prevented from being damaged, and the folded portion (peeling roll 110) is prevented from being worn away. The operation and the peeling operation of the release film 40 can be reliably performed. Moreover, since the peeling roll 110 is a roll having a bearing, since the rotation is smooth, the release film 40 can be smoothly peeled off with a small force when the release film 40 is peeled off from the polarizing film 30, The progress after the release film 40 is folded back becomes smoother.

  A guide member 130 that guides the progress of the polarizing film 30 is provided on the front side of the peeling roll 110. Since the guide surface 131 of the guide member 130 is subjected to non-adhesive surface processing, the adhesion surface of the polarizing film 30 can be prevented from adhering to the guide surface 131 of the guide member 130, and the polarizing film 30 can be smoothly advanced on the guide surface 131 of the guide member 130.

  In addition, since the guide member 130 has the leading end 132 of the guide member 130 as an edge, the distance between the leading end 132 of the guide member 130 and the attachment start end 10a of the glass substrate 10 is made as narrow as possible. In addition, the step between the front end portion 132 of the guide member 130 and the attachment start end 10a of the glass substrate 10 can be made as small as possible. Thereby, compared with the case where a folding | turning part is made into the folding | turning part which has roundness, for example (refer the broken-line circle B in FIG. 7), until the front-end | tip part 30a of the polarizing film 30 reaches | attains the sticking start end 10a of the glass substrate 10. , And the polarizing film 30 can be prevented from being bent by its own weight until the polarizing film 30 reaches the sticking start end 10a. Thereby, the front-end | tip part 30a of the polarizing film 30 which advances the guide surface 131 can be made to arrive at the sticking start end 10a of the glass substrate 10 accurately. Further, since the guide member 130 is installed so that the sticking start end 10a of the glass substrate 10 is positioned on the extension of the guide surface 131, the leading end portion of the polarizing film 30 that travels on the guide surface 131 is also provided. 30a can be made to reach the attaching start end 10a of the glass substrate 10 with high accuracy.

  The pressing roll 140 includes a first pressing roll 141 having a small diameter located on the side in contact with the polarizing film 30 and a second pressing roll 142 having a large diameter for backing up the pressing force of the first pressing roll 141. ing. Since the pressing roll 140 has such a configuration, the first pressing roll 141 has a small diameter even if the distance between the tip end portion 132 of the guide member 130 and the attachment start end 10a of the glass substrate 10 is narrow. The polarizing film 30 can be pressed without contacting the guide member 130. Moreover, since the 2nd press roll 142 also plays the role which prevents the curvature of the 1st press roll 141, the polarizing film 30 is uniformly pressed over the whole width direction (direction along the rotating shaft of the press roll 140). Can be pressed down reliably.

  Further, the dancer roll 125 is provided in the release film advancing mechanism unit 120, so that the table 20 can be used when performing the attaching operation (see, for example, FIG. 4D) for attaching the polarizing film 30 to the glass substrate 10. The operation of moving in the direction of the arrow x ′ and the winding operation of the release film 40 by a winding roll (not shown) need not be synchronized, and each operation can be performed independently. Further, during the supply operation of the polarizing film 30 by the feeder mechanism 126 (see, for example, FIG. 4B), the supply operation of the polarizing film 30 and the winding of the release film 40 by the take-up roll (not shown). It is not necessary to synchronize with the taking operation, and each operation can be performed independently.
