  As shown in FIGS. 1 and 2, the molding die roll 10 includes a roll body 1, a turnbuckle 2, a roll diameter holding portion 3, and a cylindrical stamper 9. In FIG. 1, the turnbuckle 2 is not shown for easy understanding.

  The roll body 1 is a cylindrical body having an outer diameter R centered on the rotation axis X1, and is made of a metal material such as a steel material, for example. Examples of the steel material include STKM (carbon steel pipe for machine structure) defined in JIS G3445. The roll body 1 is divided into substantially straight lines along the rotation axis X1. In other words, the roll body 1 has a gap extending along the rotation axis X1, and has end portions 1a and 1b. This gap is between the end 1a and the end 1b. The roll body 1 is preferably made of a material that can be elastically deformed so as to enlarge or reduce the outer diameter R according to the applied force. Moreover, you may change suitably the shape and size of the roll main body 1, such as an outer diameter, thickness, and length. The roll body 1 may be manufactured by irradiating a cylindrical body with a laser to form a gap, or may be manufactured by bending a flat plate having a predetermined thickness into a cylindrical shape. Moreover, the roll main body 1 is provided with the mechanical strength required for the manufacturing method of a film, and may perform a surface treatment as needed. Examples of such surface treatment include hard chrome plating treatment.

  As shown in FIG. 3, the turnbuckle 2 is provided inside the roll body 1 so as to straddle the gap of the roll body 1. Specifically, the turnbuckle 2 is preferably provided on the inner peripheral surface of the roll body 1. The turnbuckle 2 includes support portions 21 and 22, male screw portions 23 and 24, and a body portion 25.

  The support portion 21 is provided at the end portion 1 a of the roll body 1, and the support portion 22 is provided at the end portion 1 b of the roll body 1. Referring to FIG. 4 together with FIG. 3, the male screw portion 23 is rotatably supported by the support portion 21, and the male screw portion 24 is rotatably supported by the support portion 22. The male screw portion 23 may rotate around a rotation axis X2 that is substantially parallel to the rotation axis X1. Further, the male screw portion 24 may rotate around a rotation axis X3 that is substantially parallel to the rotation axis X1. The male screw portions 23 and 24 have male screws 23a and 24a, respectively. The male screw 23a may be wound in a direction opposite to that of the male screw 24a, or may be threaded. The trunk | drum 25 is a cylindrical body which has the internal thread 25a, the internal thread 25b, and the holding part 25c. The female screw 25 a is provided at one end of the trunk portion 25, and the female screw 25 b is provided at the other end of the trunk portion 25. The grip portion 25c is provided between the female screw 25a and the female screw 25b. The female screws 25a and 25b are fastened to the male screws 23a and 24a, respectively. The grip portion 25 c has a shape that is easy to grip, and has, for example, a plurality of planes on the outer peripheral surface of the body portion 25. When the gripping part 25c is gripped using a gripping tool such as a wrench or spanner, the body part 25 can be easily rotated around its axis.

  When the body portion 25 is rotated, the female screws 25 a and 25 b are rotated, and the male screw portion 23 and the male screw portion 24 are separated from or close to the body portion 25. As a result, the distance between the end 1a and the end 1b of the roll body 1 is adjusted via the support portions 21 and 22, and the gap between the roll bodies 1 is enlarged or reduced. Further, the outer diameter R of the roll body 1 is increased or reduced by expanding or reducing the gap of the roll body 1. The outer diameter R of the roll body 1 may be the same as or slightly larger than the inner diameter of the cylindrical stamper 9. The outer diameter R of the roll body 1 is preferably adjusted so that it becomes easy to press the molding surface of the cylindrical stamper 9 against the film in the film manufacturing method described later. The turnbuckle 2 can increase the outer diameter R of the roll body 1 by pushing the inner peripheral surface of the roll body 1 so as to push the gap between the roll bodies 1. Specifically, the turnbuckle 2 may enlarge the outer diameter R of the roll body 1 by pressing the end 1a and the end 1b, respectively.

  In FIG. 2, three turnbuckles 2 are provided on the inner peripheral surface of the roll body 1, but one, two, or four or more turnbuckles 2 are appropriately provided on the inner peripheral surface of the roll body 1. It may be provided.

  Referring to FIG. 1, the roll diameter holding part 3 includes support parts 31 and 32, a body part 33, and a pressing screw 34.

  The roll diameter holding unit 3 is disposed inside the roll body 1. Specifically, the support portion 31 is provided at the end portion 1 a of the roll body 1, and the support portion 32 is provided at the end portion 1 b of the roll body 1. The support portions 31 and 32 have axes 31a and 32a substantially parallel to the rotation axis X1, respectively.

  One end of the body part 33 is supported by the support part 31 so as to be movable and rotatable in the longitudinal direction of the body part 33 (here, the Z-axis direction). Referring to FIG. 5 in conjunction with FIG. 1, specifically, the body portion 33 has a hole 33a at one end thereof, and the hole 33a has a size into which the shaft 31a can be inserted. Further, the length L1 of the hole 33a in the longitudinal direction of the body portion 33 is longer than the diameter of the shaft 31a. The length L1 may be determined according to the expansion and reduction of the outer diameter R of the roll body 1.

  The other end of the trunk portion 33 is supported by the support portion 32 so as to be movable and rotatable in the longitudinal direction of the trunk portion 33 (here, the Z-axis direction). Specifically, the body portion 33 has a hole 33b at the other end, and the hole 33b has a size that allows the shaft 32a to be inserted. Further, the length L2 of the hole 33b in the longitudinal direction of the body portion 33 is longer than the diameter of the shaft 32a. The length L2 may be determined according to the expansion and contraction of the outer diameter R of the roll body 1.

  The body portion 33 has a female screw 33c between the hole 33a and the hole 33b. The female screw 33c extends in a direction intersecting with the longitudinal direction of the body portion 33 (here, for example, the Y-axis direction). It is provided so that it may penetrate.

  The pressing screw 34 is fitted to the female screw 33c, and can be moved in the axial direction (here, the Y-axis direction) by rotating. The pressing screw 34 protrudes toward the inner peripheral surface of the roll body 1. A nut 35 is fastened to the pressing screw 34. The position of the pressing screw 34 may be fixed by suppressing the loosening of the pressing screw 34 using the nut 35.

  As shown in FIG. 1, the guide plate 4 is a plate-like body having a recess 4a. The guide plate 4 is disposed on the inner peripheral surface of the roll body 1 so as to close the space between the end 1a and the end 1b. Further, the guide plate 4 is disposed on the inner peripheral surface of the roll body 1 such that the recess 4 a comes into contact with the pressing screw 34 of the roll diameter holding unit 3. The guide plate 4 may be pressed from the pressing screw 34 toward the inner peripheral surface of the roll body 1 with a predetermined pressure. The pressure applied to the guide plate 4 by the pressing screw 34 is such that when the molding surface of the cylindrical stamper 9 is pressed against the film in the film manufacturing method described later, the end 1a and the end 1b maintain a circular shape. It is good to adjust so that it is possible.

  The cylindrical stamper 9 is a cylindrical body having an inner diameter that is the same as or larger than the outer diameter R of the roll body 1, and the outer peripheral surface of the cylindrical stamper 9 has a molding surface. The molding surface has, for example, a fine uneven pattern, and the depth is, for example, 0.1 to 100 μm. The fine concavo-convex pattern includes a complicated three-dimensional shape, such as a cylindrical lens, a prism lens, or a microlens. The cylindrical stamper 9 is attached to the roll body 1 so as to cover the outer peripheral surface of the roll body 1. The cylindrical stamper 9 is made of, for example, a metal material. An example of such a metal material is Ni. The cylindrical stamper 9 may be formed by rounding one rectangular plate-shaped stamper, butting the ends of each other and welding them, or welding the ends of two rectangular plate-shaped stampers. You may form by doing.

  Here, the outer diameter R of the roll main body 1 is enlarged by rotating the body portion 25. By increasing the outer diameter R of the roll body 1, the adhesion between the roll body 1 and the cylindrical stamper 9 is enhanced. Further, the guide plate 4 is pressed against the end portions 1 a and 1 b of the roll body 1 by rotating the pressing screw 34. The ends 1a and 1b of the roll body 1 are not easily deformed even when pressure is applied in a direction (here, the Y-axis direction) toward the rotation axis X1 of the roll body 1.

(Film production method)
Next, the manufacturing method of the film using the shaping | molding die roll concerning Embodiment 1 is demonstrated using FIG. This film manufacturing method may also be referred to as roll-to-roll molding. FIG. 6 is a diagram showing a film manufacturing method.

As shown in FIG. 6, first, the mold roll 10 and the pair of rolls 73 and 74 are opposed to each other. The cylindrical stamper 9 has, for example, a flat portion 9a and a concave portion or a convex portion 9b. The concave portion or the convex portion 9b may be arranged in a predetermined pattern on the flat portion 9a, and may constitute a fine concave / convex pattern, for example. An example of the cylindrical stamper 9 shown in FIG. 6 has a flat surface portion 9a and a concave portion 9b.
Subsequently, a UV (Ultraviolet) lamp 75 is disposed between the pair of rolls 73 and 74. More specifically, the UV lamp 75 irradiates ultraviolet rays in a predetermined direction. The direction of the UV lamp 75 is adjusted so that the ultraviolet rays are irradiated to the outer peripheral surface of the molding die roll 10.

  Subsequently, a base film 64 coated with an ultraviolet curable resin 63 is sandwiched between the mold roll 10 and the pair of rolls 73 and 74. The ultraviolet curable resin 63 and the base film 64 are an example of a transfer target. Here, as shown in FIG. 1, since the guide plate 4 is pressed against the ends 1 a and 1 b of the roll body 1, the ultraviolet curable resin 63 and the base film 64 are placed on the ends 1 a and 1 b of the roll body 1. Even if pressure is applied, the end portions 1a and 1b are not easily deformed. Therefore, the roll body 1 can hold the outer diameter R in the cross section, particularly at the end portions 1a and 1b. Moreover, the roll main body 1 can maintain a cylindrical shape. The mold roll 10 can be stably pressed against the ultraviolet curable resin 63 and the base film 64.

  Further, the ultraviolet curable resin 63 and the base film 64 are passed between the molding die roll 10 and the pair of rolls 73 and 74, and ultraviolet rays are irradiated from the UV lamp 75 to the ultraviolet curable resin 63 and the cylindrical stamper 9. As a result, the ultraviolet curable resin 63 is transferred to the surface shape of the cylindrical stamper 9. Then, since the base layer 63a and the fine structure portion 63b are formed in the ultraviolet curable resin 63, the resin film 60 with a fine structure is formed. The fine structure portion 63b has the same shape as the shape in which the concave portion 9b is inverted.

  As described above, according to the molding die roll according to the first embodiment, the diameter of the roll main body is adjusted to improve the adhesion between the cylindrical roll main body and the continuous cylindrical stamper that is seamless in the circumferential direction. be able to. As a result, the molding surface of the seamless cylindrical stamper can be pressed against the material to be transferred, and the surface shape of the molding surface can be continuously transferred to the material to be transferred. Therefore, productivity is high.

  Moreover, according to the shaping | molding die roll concerning Embodiment 1, a guide plate can be pressed against the clearance gap between roll bodies, and the diameter of a roll body can be hold | maintained. Therefore, it can be stably transferred to the transfer object with high productivity.

Embodiment 2. FIG.
Next, the molding die roll according to the second embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a side view of the main part of the molding die roll according to the second embodiment. FIG. 8 is a front view of the main part of the molding die roll according to the second embodiment. The molding die roll according to the second embodiment has the same configuration as the molding die roll according to the first embodiment except that a pneumatic cylinder is included instead of the turnbuckle. A description of the common configuration will be omitted, and a different configuration will be described.

  As shown in FIGS. 7 and 8, the mold roll 20 (not shown) includes a pneumatic cylinder 5. The pneumatic cylinder 5 includes rods 51 and 52 and a cylinder body 53. The pneumatic cylinder 5 is disposed inside the roll body 1. The rod 51 is provided at one end 1a of the roll body 1 and extends toward the other end 1b. The rod 52 is provided at the other end 1b of the roll body 1 and extends toward the one end 1a. The cylinder body 53 includes rod sliding holes 53a and 53b and a gripping portion 53c. The rod sliding hole 53 a is provided at one end of the cylinder body 53, and the rod sliding hole 53 b is provided at the other end of the cylinder body 53. The rod sliding hole 53a is inserted so that the rod 51 can slide, and the rod sliding hole 53b is inserted so that the rod 52 can slide. The grip 53c is disposed between the rod sliding hole 53a and the rod sliding hole 53b. The grip portion 53 c has a shape that is easy to grip, and has, for example, a plurality of planes on the outer peripheral surface of the cylinder body 53. The cylinder body 53 has an air suction port (not shown), and air is fed from the air suction port to move the rods 51 and 52 away from the cylinder body 53 (here, + Z axis direction or −Z axis direction). ) Respectively. The relative position of the rods 51 and 52 with respect to the cylinder body 53 can be maintained by closing the air inlet after reaching a predetermined pressure. The pneumatic cylinder 5 can increase the outer diameter R of the roll body 1 by pushing the inner peripheral surface of the roll body 1 so as to push the gap between the roll bodies 1. Specifically, the pneumatic cylinder 5 may enlarge the outer diameter R of the roll body 1 by pressing the end 1a and the end 1b, respectively.

  As described above, according to the molding die roll according to the second embodiment, the diameter of the roll main body is adjusted to improve the adhesion between the roll main body and the cylindrical stamper, similarly to the molding die roll according to the first embodiment. be able to. As a result, the molding surface of the seamless cylindrical stamper can be pressed against the material to be transferred, and the surface shape of the molding surface can be continuously transferred to the material to be transferred. Therefore, productivity is high.

  In the molding die rolls according to the first and second embodiments, the turnbuckle and the pneumatic cylinder are used, respectively, but technical means for expanding the roll diameter, that is, roll diameter expanding means may be used. Various technical means can be used as the roll diameter expanding means. For example, a hydraulic cylinder, a linear actuator, or the like may be used.

  Next, Example 1 will be described.

Example 1 is a molding die roll having the same configuration as the molding die roll according to the first embodiment. The cylindrical stamper used was formed by the following process. First, two nickel stampers having a thickness of 0.3 mm were prepared and cut so that the total length of them was 1072.05 mm. Furthermore, the cylindrical stamper was formed by welding the ends of the cut nickel stamper using microplasma welding. The cylindrical stamper has a microplasma welded portion welded by microplasma welding. On the molding surface of the formed cylindrical stamper, cylindrical holes having a depth of 1 μm are carved in a range of 300 mm × 500 mm with a pitch of 2.5 μm.
As the roll body, a roll having an outer diameter of 341.243 mm and an outer peripheral length of 1071.5 mm was used.

After the used roll body is covered with the cylindrical stamper, the outer diameter R of the roll body is expanded by a turnbuckle. Thus, the cylindrical stamper is held on the roll body. Here, the outer diameter R of the roll body was 341.5 mm.
Subsequently, a molding die roll was formed by pressing the guide plate against the gap between the roll bodies.

A film was manufactured using the above-described film manufacturing method.
As the ultraviolet curable resin, a UV curable resin having a viscosity of 100 mPa · sec at 25 ° C. was used. As the base film, a PET (polyethylene terephthalate) film having a thickness of 100 μm and a width of 340 mm was used. The used PET film has high transparency, and both surfaces thereof are subjected to easy adhesion treatment. The UV curable resin was applied to the PET film using a slot die. Here, the coated UV curable resin had a thickness of 15 μm and a width of 280 mm.

  Even after the production of the resin film with a fine structure was completed, the coated cylindrical stamper was held on the roll body.

As a result of evaluating the surface of the resin film with a fine structure, the pattern transfer rate of the pattern portion in the cylindrical stamper was 100%. Further, the thickness was 6 ± 2 μm on the average in the width direction, and the average was 6 ± 3 μm in the molding direction. The entire molding surface of the cylindrical stamper was able to be transferred to the resin film with a fine structure. The entire molding surface of the cylindrical stamper is a rectangle having a width of 300 mm and a length of 500 mm. Since the vicinity of the end of the roll body was pressed by the guide plate, there was no resin thickness fluctuation in the vicinity of the end of the roll body.
The unevenness of the microplasma weld in the cylindrical stamper was 15 μm. Further, even when the continuously formed film 500 m was wound with a tension of 50 N, there was no seam mark and the quality was not deteriorated by unevenness.
In the vicinity of the end of the roll main body, the unusable range as the molding surface of the molding die roll was about 20 mm due to scratches generated during microplasma welding.
The time required for microplasma welding was one day. The time required for the step of fitting the cylindrical stamper into the roll body and the step of adjusting the outer diameter R of the roll body was about 2 hours, and the test could be performed in a short time. Moreover, the resin thickness and the unevenness were measured using a contact-type film thickness meter.
Moreover, even if a 10,000-meter film was shape | molded, the mold release force of Example 1 did not change a lot. This is thought to be because the nickel plasma stamper is joined using microplasma welding, so the microplasma weld is made of the same type of material (here, Ni).

(Comparative example)
Next, for comparison with Example 1, Comparative Example 1 and Comparative Example 2 will be described.

In Comparative Example 1, first, two nickel stampers having a thickness of 0.3 mm were attached to the outer peripheral surface of the roll body via an adhesive tape. Specifically, the nickel stamper was attached to the outer peripheral surface of the roll body so that a gap of about 2 to 3 mm was formed between the nickel stampers.
After a copper tape having good adhesion with the solder was applied to the outer peripheral surface of the roll body, soldering was performed so that the solder was buried in the gap. The solder layer was formed to be thicker than the stamper thickness, and the formed solder layer was polished with sandpaper so as to have the same thickness as the stamper thickness.

There was no problem in forming the pattern portion of the film formed with this stamper.
The unevenness in the gap was 30 μm. Moreover, the unevenness | corrugation difference close to 100 micrometers occurred locally. This is presumably because nests were generated in the solder layer. Even when 100 m of continuously formed film was wound with a tension of 20 N, seam marks were generated, and the quality was deteriorated due to unevenness in the gap.
When the film was molded at about 50 m, it could be impossible to mold any more. One reason for this is that the UV curable resin that has entered the concave and convex portions is cured, and a part of the solder layer in the gap portion is moved to the film side. Another reason is that the UV curable resin remains on the solder side.
In the vicinity of the end of the roll main body, the area that cannot be used as the molding surface of the molding die roll was about 30 mm due to scratches or the like generated when the solder layer was polished.
It took 1 day to process the stamper. The time required for the step of attaching the nickel stamper to the outer peripheral surface of the roll body was one day. The time taken for soldering and polishing was 2 days.

(Comparative Example 2)
In Comparative Example 2, as in Comparative Example 1, two nickel stampers having a thickness of 0.3 mm were first attached to the outer peripheral surface of the roll body with an adhesive tape. Specifically, the nickel stamper was attached to the outer peripheral surface of the roll body so that a gap of about 3 mm was formed between the nickel stampers.
Furthermore, a rod made of the same type of material as that of the nickel stamper was filled in the gap and welded to integrate the rod with the nickel stamper. The weld was smoothed using sandpaper.

There was no problem in forming the pattern portion of the film formed with this stamper.
The unevenness in the gap was 50 μm. Further, it was visually confirmed that a large swell occurred in the gap. One reason for this is that the gap is welded on the outer peripheral surface of the cylindrical roll body, resulting in welding variations.
Even when 100 m of a continuously formed (transferred) film was wound with a tension of 20 N, the quality was deteriorated due to unevenness in the gap.
In the vicinity of the end of the roll body, the range that cannot be used as the forming surface of the forming die roll was about 40 mm due to scratches caused when welding or polishing the welded portion.
The time taken for the welding process was 5 days.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, in the molding die roll according to the first and second embodiments, the cylindrical roll main body is used, but a cylindrical roll main body having shafts extending in the longitudinal direction at both ends may be used. Further, the cylindrical roll may have a central axis and a plurality of spokes connecting the central axis and the inner peripheral surface of the roll body, and the spoke may include a roll diameter expanding means. .
