Description

  The present invention relates to a transfer apparatus and a transfer method, and more particularly to a transfer device for transferring a transfer pattern of a mold onto a fibrous (string-like) substrate.

  In recent years, a mold (mold) is formed by forming an ultrafine transfer pattern on a quartz substrate or the like by an electron beam drawing method or the like, and the mold is pressed to a molded product with a predetermined pressure, and the mold is formed. A nanoimprint technique for transferring a transfer pattern has been researched and developed (for example, see Non-Patent Document 1).

  As a method for forming a nano-order fine pattern (transfer pattern) at a low cost, an imprint method using a lithography technique has been devised. This molding method is roughly classified into a thermal imprint method and a UV imprint method.

  In the thermal imprint method, a mold is pressed against a substrate, heated to a temperature at which a resin made of a thermoplastic polymer (thermoplastic resin) can flow sufficiently, and the resin flows into a fine pattern. The resin is cooled to below the glass transition temperature, and after the fine pattern transferred to the substrate is solidified, the mold is pulled apart.

  In the UV imprint method, a transparent mold capable of transmitting light is used, and the UV radiation is applied by pressing the mold against the UV curable liquid. After radiating light for an appropriate time to cure the liquid and transfer the fine pattern, the mold is pulled apart.

  The above-described imprint (transfer) may be performed on a fibrous base material instead of the substrate. In this case, the size of the transfer pattern is the same as or larger than the conventional one.

  By transferring the transfer pattern onto the fibrous base material, for example, a pattern such as an electrical wiring or a liquid channel is formed on the fibrous base material (see, for example, Patent Document 1).

  A transfer apparatus 1 shown in FIGS. 1 and 2 is an apparatus for transferring a transfer pattern M1 formed on a mold M onto a small-diameter fibrous (thread-like) substrate W, and a raw reel setting unit 3 And a take-up reel installation unit 5, a substrate transfer unit (substrate transfer means) 7, and a transfer unit 9.

  Hereinafter, for convenience of explanation, in this specification, one horizontal direction is defined as the X-axis direction, another horizontal direction that is orthogonal to the X-axis direction is defined as the Y-axis direction, and the vertical direction is defined as Z. Axial direction.

  A fibrous base material W before transfer is wound around the original fabric reel 11 installed in the original fabric reel installation section 3.

  The original fabric roll 13 includes a columnar or cylindrical original fabric reel (winding frame) 11 and a fibrous substrate W wound around the outer periphery of the original fabric reel 11. The original fabric reel 11 (original fabric roll 13) installed in the original fabric reel installation section 3 rotates about the central axis C1, so that the fibrous base material W is fed out from the original fabric reel 11. It has become.

  The take-up reel 15 installed in the take-up reel installation unit 5 is configured to take up the fibrous base material W fed from the original fabric reel 11 installed in the original fabric reel installation unit 3.

  The take-up roll 17 is assumed to be composed of a columnar or cylindrical take-up reel (winding frame) 15 and a fibrous substrate W taken up on the outer periphery of the take-up reel 15. When the take-up reel 15 installed in the take-up reel installation unit 5 rotates about the central axis C4, the fibrous base material W is taken up by the take-up reel 15 and the take-up roll 17 is rotated. It is to be generated.

  The fibrous base material W is made of a material such as resin or glass and is formed in an elongated linear shape with a small diameter. A predetermined shape in which the cross section of the fibrous base material W (the cross section of the plane perpendicular to the longitudinal direction of the fibrous base material W) has the same or slightly different vertical and horizontal dimensions. It has become.

  For example, the cross section of the fibrous base material W has a circular shape with a diameter of about 3 mm. Although not shown, the fibrous base material W may be formed in a cylindrical shape such as a cylindrical shape. In this case, the shape of the cross section of the fibrous base material W is a ring shape (the first circle on one plane and the second circle whose diameter is smaller than that of the first circle and the center coincides with the first circle). A shape obtained by drawing a circle and removing the second circle from the first circle). Furthermore, although the internal space of the cylindrical fibrous base material W is hollow, it may contain a material such as a conductive material. In this case, the conductive material may be filled in the entire interior space, may be provided at a predetermined interval, or may be provided in another manner. .

  Further, the fibrous base material W has flexibility with respect to bending, and is wound around the raw fabric reel 11 and the take-up reel 15.

  For example, a predetermined tension is applied between the substrate reel 11 installed in the substrate reel installation unit 3 and the take-up reel 15 installed in the take-up reel installation unit 5. The fibrous base material W extending linearly is transferred from the original fabric reel 11 installed in the original fabric reel installation section 3 to the take-up reel 15 installed in the take-up reel installation section 5. .

  This transfer is performed by appropriately winding the fibrous base material W fed from the original fabric reel 11 installed in the original fabric reel installation unit 3 with the take-up reel 15 installed in the take-up reel installation unit 5. It has become so.

  If it demonstrates in detail, the base material transfer part 7 will be able to move the extending | stretching fibrous base material W at a fixed speed | rate in this extending | stretching direction, for example. Further, for example, after the fibrous base material W that has been stretched is moved by a certain distance in the stretching direction, the position after the movement (position in the stretching direction) can be maintained by the base material transfer unit 7. It is like that. Further, after the fibrous base material W is moved by a certain distance by the base material transfer unit 7, the center axis CW (see FIG. 8 etc.) extending in the longitudinal direction of the fibrous base material W is the center of rotation. Thus, the extending fibrous base material W can be rotated. The above-described transfer mode performed by the base material transfer unit 7 will be described in detail later, but can be determined as appropriate depending on the transfer mode to the fibrous base material W.

  In addition, as described above, the stretched fibrous base material W is transferred by rotating the take-up reel 15 installed in the take-up reel installation unit 5. Application of tension to the stretched fibrous base material W is performed by applying rotational resistance to the original fabric reel 11 installed in the original fabric reel installation section 3. To maintain the position of the stretched fibrous base material W after moving (after transfer), the rotation of the take-up reel 15 installed in the take-up reel installation unit 5 is stopped and installed in the original fabric reel installation unit 3. A predetermined rotational torque (torque in the direction of winding up the fed fibrous base material W) is applied to the raw fabric reel 11 that has been provided. In this case, the take-up reel 15 installed in the take-up reel installation unit 5 is not rotated by a brake (for example, a servo brake).

  The fibrous base material W extending between the original fabric reel 11 installed in the original fabric reel installation section 3 and the take-up reel 15 installed in the take-up reel installation section 5 has a longitudinal direction (extension direction). ; X-axis direction) and does not move in the direction orthogonal to the stretching direction. That is, the stretched fibrous base material W does not move in the Y-axis direction and does not move in the Z-axis direction.

  In the transfer unit 9, a transfer pattern (for example, a fine transfer pattern) M1 formed on the mold M is transferred to the extending fibrous base material W. The pattern W1 (see FIG. 29) formed on the fibrous base material W by the transfer is reversed with respect to the transfer pattern M1 of the mold M.

  The transfer unit 9 is provided between the raw reel installation unit 3 and the take-up reel installation unit 5. The transfer section 9 includes a first mold installation section (for example, an upper mold installation section) 19 in which a first mold (for example, an upper mold) M is installed, and a second mold (for example, a lower mold) M5 in which a first mold (for example, an upper mold) is installed. 2 mold installation parts (lower mold installation parts) 21 (see FIG. 10 and the like). Then, the stretched fibrous base material W is sandwiched between the upper mold M3 installed in the upper mold installation section 19 and the lower mold M5 installed in the lower mold installation section 21 so that the transfer is performed. It has become.

  Although the transfer in the transfer unit 9 will be described in detail later, when the fibrous substrate W that has been stretched is transferred at a constant speed by the substrate transfer unit 7, or by the substrate transfer unit 7. This is done when the stretched fibrous base material W is moved by a certain distance in this stretching direction and the position after this movement is maintained.

  The transfer device 1 is provided with a plurality of transfer portions 9A, 9B, 9C (see FIG. 3). The transfer device 1 is configured to perform one type of transfer selected from a plurality of types of transfer modes by selecting one of the transfer units 9A, 9B, and 9C.

  In FIG. 3, each of the transfer portions 9A, 9B, and 9C includes frame bodies 53A, 53B, and 53C. However, as shown in FIG. 4, each transfer portion 9A, 9B, and 9C has one frame. The frame 53 may be provided. And you may enable it to select one transfer part of each transfer part 9A, 9B, 9C, with the fibrous base material W extended | stretched to the X-axis direction.

  That is, in the embodiment shown in FIG. 4, since there is no obstacle (a part of the frame 53) between the transfer portion 9A and the transfer portion 9B, and between the transfer portion 9B and the transfer portion 9C, One of the transfer portions 9A, 9B, 9C can be selected while the base material W is stretched in the X-axis direction.

  Further, in the transfer device 1, as described above, using any one of the transfer portions 9A, 9B, 9C, etc., the transfer shown in FIG. 5, the transfer shown in FIG. 8, the transfer shown in FIG. One of the modes of transfer shown in FIG. 12 and the like can be transferred.

  As shown in FIGS. 5 and 6, the transfer unit 9 </ b> A heats and softens the fibrous base material W by the heating unit, and sandwiches the fibrous base material W stretched by the rollers M <b> 7 and M <b> 9. The fibrous base material W stretched by the base material transport unit 7 is transported at a predetermined speed, and is transferred while rotating the rollers M7 and M9. The rotation center axes C8 and C9 of the rollers M7 and M9 are orthogonal to the extending direction of the extending fibrous base material W (the rotation center axes C8 and C9 extending in the Y-axis direction are X Since it is away from the fibrous base material W extending in the axial direction, it does not actually intersect, but is orthogonal when viewed in plan).

  Further, as shown in FIGS. 8, 9 and the like, the transfer unit 9A heats and softens the fibrous substrate W by the heating unit, and the fibrous substrate W stretched by the rollers M7 and M9. The position of the fibrous base material W sandwiched and stretched by the base material transport unit 7 (position in the direction perpendicular to the stretching direction of the fibrous base material W) is maintained (stretching by the base material transport unit 7). The transfer is performed while rotating the rollers M7 and M9 while the transfer of the fibrous base material W being stopped is stopped). The rotation center axes C8 and C9 of the rollers M7 and M9 are parallel to the extending direction of the extending fibrous base material W.

  Next, the transfer portion 9A will be described in more detail.

  As shown in FIGS. 5 and 6, the transfer unit 9 </ b> A includes, for example, a frame 53 </ b> A, a lower table 55, a lower roller support 57, an upper table 59, and a moving body 61 provided inside the frame 53 </ b> A. And an upper roller support 63.

  The lower table 55 is supported by the frame 53A below the frame 53A via a linear guide bearing (not shown), and is movable with respect to the frame 53A in the Y-axis direction. The lower table 55 can be moved and positioned by an actuator such as a servo motor 65 under the control of the control device 39.

  The lower roller support 57 is supported by the lower table 55 on the upper side of the lower table 55 via a bearing (not shown), and is rotatable about the axis C7. The axis C7 is an axis that passes through the center of the lower roller support 57 (lower roller M9) and extends in the Z-axis direction. Further, the lower roller support 57 is freely rotatable and positionable by an actuator such as a servo motor 67 under the control of the control device 39.

  The lower roller support 57 is provided with a lower roller M9. The lower roller M9 is supported by the lower roller support 57 above the lower roller support 57 via a bearing (not shown), and is rotatable about the axis C9. The axis C9 is an axis that passes through the center of the lower roller M9 and extends in the horizontal direction. Further, the shaft C9 extends in the Y-axis direction (see FIGS. 5 and 6) or the X-axis direction (see FIGS. 8 and 9) in accordance with the rotation of the lower roller support 57. Further, the lower roller M9 is rotatable and positionable by an actuator such as a servo motor 69 under the control of the control device 39.

  The upper table 59 is supported by the frame 53A on the upper side of the frame 53A via a linear guide bearing (not shown), and is movable with respect to the frame 53A in the Y-axis direction. The upper table 59 can be moved and positioned by an actuator such as a servo motor 71 under the control of the control device 39.

  The moving body 61 is supported by the upper table 59 below the upper table 59 via a bearing (not shown), and is movable in the Z-axis direction. The moving body 61 is movable and positionable by an actuator such as a servo motor 73 under the control of the control device 39.

  The upper roller support 63 is supported by the moving body 61 below the moving body 61 via a bearing (not shown), and is rotatable about the axis C7. Further, the upper roller support 63 can be rotated and positioned by an actuator such as a servo motor 75 under the control of the control device 39.

  The upper roller support 63 is provided with an upper roller M7. The upper roller M9 is located above the lower roller M9, and is supported by the upper roller support 63 below the upper roller support 63 via a bearing (not shown), with the axis C8 as the center. It can turn freely. The axis C8 is an axis that passes through the center of the upper roller M7 and extends in the horizontal direction. The shaft C8 extends in the Y-axis direction (see FIGS. 5 and 6) or the X-axis direction (see FIGS. 8 and 9) in accordance with the rotation of the lower roller support 57, for example, in synchronization with the shaft C9. It is like that. The upper roller M7 can be rotated and positioned by an actuator such as a servo motor 77 under the control of the control device 39, for example, in synchronization with the lower roller M9.

  Then, by appropriately driving the servo motor 73 from the state shown in FIG. 7, for example, as shown in FIGS. 5 and 6, the fibrous base material W is sandwiched between the upper roller M7 and the lower roller M9. Yes.

  When the servo motors 51, 69, 77 and the like are appropriately driven in a state where the fibrous base material W is sandwiched between the upper roller M7 and the lower roller M9 as described above, the upper roller M7 and the lower roller M9 are rotated to form a fibrous shape. The substrate W moves (transfers) from the left to the right in FIG. 6 at a predetermined speed, and the transfer pattern formed on the outer periphery of the upper roller M7 and the lower roller M9 is heated by the heating unit. The material W is transferred to the material W.

  In the case of such transfer, the moving speed of the fibrous base material W is equal to the outer peripheral speeds (peripheral speeds) of the upper roller M7 and the lower roller M9. Further, for example, the servo motor 69 that rotationally drives the lower roller M9 may be omitted, and the lower roller M9 may be rotated according to the rotation of the upper roller M7.

  The transfer shown in FIGS. 5, 6, and 7 will be described in more detail.

  First, as shown in FIG. 7, when the upper roller M7 is lifted away from the lower roller M9, as shown in FIG. 17 (a), the fiber stretched in the X-axis direction with the lower roller M9. There is a slight distance L1 between the upper substrate M and the fibrous base material W, and there is a distance L2 between the upper roller M7 and the fibrous base material W. “D1” is the diameter of the fibrous base material W.

  When the upper roller M7 is lowered from the state shown in FIG. 7 and the fibrous base material W is sandwiched between the lower roller M9 and the upper roller M7 as shown in FIGS. 5 and 6, as shown in FIG. In addition, the fibrous base material W is sandwiched between the rollers M7 and M9 with a predetermined pressing force.

  In the state shown in FIG. 17B, the fibrous base material W is slightly inclined with respect to the X axis, but the distance between each of the rollers M7 and M9 and the original reel auxiliary roller 33 is the distance L1. The distance between the rollers M7 and M9 and the take-up reel auxiliary roller 47 is sufficiently larger than the distance L1, so that the transfer to the fibrous base material W is not adversely affected.

  When the lower roller M9 is movable and positioned in the Z-axis direction and the fibrous base material W is sandwiched between the rollers M7 and M9, the lower roller M9 is moved by a slight distance L1, and the fibers are moved by the rollers M7 and M9. The substrate W may be sandwiched.

  Here, specific examples of the upper roller M7 and the lower roller M9 will be described.

  The upper roller M7 and the lower roller M9 shown in FIGS. 5, 6, 7, and 17 are formed in a substantially cylindrical shape, and the roller M7 is provided on at least one of the side surface of the upper roller M7 and the side surface of the lower roller M9. , M9 is provided with a number of projections that are considerably smaller than the diameter of M9.

  The fibrous base material W after the transfer using the upper roller M7 and the lower roller M9 shown in FIGS. 5, 6, 7, and 17 maintains a columnar or cylindrical form.

  The lower roller M9 shown in FIG. 29 is formed in a columnar shape, and no transfer pattern is formed on the lower roller M9. In this case, the lower roller M9 functions as a backup roll. A transfer pattern M1 is formed on the upper roller M7 shown in FIG.

  The transfer pattern M1 of the upper roller M7 shown in FIG. 29 is composed of a large transfer pattern M11 and a small transfer pattern M13. The large transfer pattern M1 is formed of a plurality of convex portions having a predetermined width and a predetermined height. In the large transfer pattern M1, the width direction coincides with the circumferential direction of the upper roller M7, the height direction coincides with the radial direction of the upper roller M7, and the longitudinal direction coincides with the extending direction of the axis C8 of the upper roller M7. And provided on the side surface of the upper roller M7. Each of the large transfer patterns M1 is provided at a predetermined interval in the circumferential direction of the upper roller M7.

  The small transfer pattern M13 includes a plurality of convex portions that are sufficiently small with respect to the outer diameter of the upper roller M7, and is provided on the top of the convex portion of the large transfer pattern M1.

  A large concave portion W3 and a small concave portion W5 are formed as a transfer pattern W1 on the fibrous base material W after being transferred using the rollers M7 and M9 shown in FIG. Note that the lower roller M9 shown in FIG. 29 may have the same form as the upper roller M7.

  In each of the rollers M7 and M9 shown in FIG. 30, a concave portion (for example, a “V” -shaped groove) M15 is formed as the transfer pattern M1. The cross section of the fibrous base material W after being transferred using the rollers M7 and M9 shown in FIG. 30 is rectangular, for example.

  5, 6, 7 and 17, as already described, the rotation center axes C8 and C9 of the rollers M7 and M9 extend in the Y-axis direction, and the fibrous base material W is stretched. Although orthogonal to the direction (X-axis direction), as shown in FIGS. 8 and 9, the transfer center 9A extends the rotation center axes C8 and C9 of the rollers M7 and M9 in the X direction (fibrous shape). It is also possible to perform transfer to the fibrous base material W by each of the rollers M7 and M9 (extending in parallel with the base material W). In this case, as already described, the movement of the fibrous base material W in the X-axis direction (longitudinal direction) is not performed.

  The transfer shown in FIGS. 8 and 9 will be described in more detail.

  First, as shown in FIG. 18A, in the Y-axis direction, the upper roller M7 is separated from the fibrous base material W and is positioned on the right side of the fibrous base material W, and the lower roller M9 is located on the fibrous base material. It is located on the left side of the fibrous base material W away from W. Further, in the Z-axis direction, the upper roller M7 is separated from the fibrous base material W and positioned on the upper side of the fibrous base material W, and the lower roller M9 is separated from the fibrous base material W and Located on the lower side. The distance L4 between the upper roller M7 and the fibrous base material W is substantially equal to or slightly smaller than the diameter d1 of the fibrous base material W. The lower roller M9 and the fibrous base material W are separated by a very small distance L3.

  From the state shown in FIG. 18A, the upper roller M7 is moved leftward at a predetermined speed while rotating the upper roller M7 around the axis C8 at a predetermined angular velocity. At the same time (synchronized), the lower roller M9 is moved rightward at a predetermined speed while rotating the lower roller M9 about the axis C9 at a predetermined angular speed.

  By rotating and moving the rollers M7 and M9 as described above, the fibrous base material W is sandwiched between the rollers M7 and M9 as shown in FIG. Transfer is made to W. After this transfer, the rollers M7 and M9 are rotated and moved as described above, so that the state shown in FIG.

  When transfer is performed in the manner shown in FIGS. 8, 9, and 18, when the fibrous base material W may be twisted, the fibrous base material W (raw material reel) is centered on the axis CW. The rotating body 29 and the take-up reel rotating body 43) may be rotated.

  Incidentally, the transfer device 1 is provided with a transfer unit 9B and a transfer unit 9C in addition to the transfer unit 9A. Details of the transfer unit 9B and the transfer unit 9C will be described later.

  Each of the transfer portions 9A, 9B, and 9C is placed on the transfer portion mounting body 79 and arranged side by side in the Y-axis direction. The frame body 53A of the transfer section 9A, the frame body 53B of the transfer section 9B, and the frame body 53C of the transfer section 9C are provided integrally with the transfer section mounting body 79.

  The transfer unit mounting body 79 (each transfer unit 9A, 9B, 9C) is provided between the web reel installation unit 3 and the take-up reel installation unit 5 in the X-axis direction. The transfer unit mounting body 79 is supported by the base body 25 on the upper side of the base body 25 via the linear guide bearing 81 and is movable with respect to the base body 25 in the Y-axis direction. The transfer unit mounting body 79 can be moved and positioned by an actuator such as a servo motor 83 under the control of the control device 39.

  Thereby, in the transfer apparatus 1, it can transfer to the fibrous base material W using one transfer part of each transfer part 9A, 9B, 9C.

  By the way, an intermittent feeding unit 85 may be provided in the transfer device 1 to constitute the base material transport unit 7. The intermittent feed unit 85 is for performing more accurate control of the moving speed and feed amount of the fibrous base material W in the X-axis direction instead of the servo motor 51 of the take-up reel installation body 45. .

  For example, the intermittent feeding unit 85 is provided between the transfer unit 9 and the take-up reel installation unit 5 and includes a gripping body support body 87, a lower gripping body 89, and an upper gripping body 91. .

  The holding body support 87 is provided integrally with the base body 25. The lower grip body 89 is supported by the grip body support body 87 via a linear guide bearing (not shown) above the grip body support body 87, and is movable with respect to the grip body support body 87 in the X-axis direction. Yes. Further, the lower gripping body 89 can be moved and positioned with respect to the gripping body support 87 by an actuator such as a linear motor under the control of the control device 39.

  The upper grip body 91 is supported by the lower grip body 89 via a linear guide bearing (not shown) above the lower grip body 89 and is movable with respect to the lower grip body 89 in the Z-axis direction. The upper grip body 91 is movable with respect to the lower grip body 89 by an actuator such as an air cylinder under the control of the control device 39.

  The intermittent feeding unit 85 transfers the fibrous base material W in the X-axis direction as follows. First, as shown in FIG. 27A, the upper gripping body 91 is lowered while the gripping bodies 87 and 89 are positioned on the upstream side of the fibrous base material W and the upper gripping body 91 is raised. Then, the fibrous base material W is held by the holding bodies 89 and 91 (see FIG. 27B).

  Subsequently, the grip bodies 89 and 91 are moved by a predetermined distance to the downstream side of the fibrous base material W (FIG. 27C). The fibrous substrate W is transferred by this movement. After the transfer is completed, the upper gripping body 91 is raised, and the gripping of the fibrous base material W by the gripping bodies 89 and 91 is released.

  In addition, in the intermittent feed unit 85 shown in FIG. 27, the transfer of the fibrous base material W becomes intermittent (each gripping body 89, 91 is shown in FIG. 27 (a) from the state shown in FIG. 27 (d)). When returning to the state, the transfer of the fibrous base material W must be stopped). Therefore, as shown in FIG. 28, a plurality of sets such as two sets, such as two sets, are arranged side by side in the X-axis direction, and each of the grip bodies 89, 91 is moved as appropriate, so that the fibrous base material W 85A may be configured so that the transfer device 1 can be continuously transferred and provided in the transfer apparatus 1 instead of the intermittent feed unit 85.

  Further, the intermittent feeding unit 85 or the feeding unit 85 </ b> A may be provided on the upstream side of the transfer unit 9. That is, the intermittent feeding unit 85 or the feeding unit 85A may be provided between the transfer unit 9 and the original fabric reel auxiliary roller 33. In this case, it is necessary to apply a predetermined tension to the fibrous base material W extending between the intermittent feeding unit 85 or the feeding unit 85A and the original reel 11 installed in the original reel installation unit 3. Therefore, it is assumed that the rotation output shaft of the motor 51 and the take-up reel installation body 45 are connected via the powder clutch.

  Next, the transfer portion 9B will be described in detail.

  The transfer portion 9B shown in FIGS. 10, 11 and the like also performs transfer by the thermal imprint method in the same manner as the transfer portion 9A. The transfer portion 9B shown in FIG. A heating unit (not shown) for heating the material W is provided. The heating unit is configured by a heater or the like provided in the flat upper mold M3 and the flat lower mold M5 in the same manner as the transfer unit 9A. The upper mold M3 and the lower mold M5 are also made of a metal such as nickel.

  The transfer pattern (not shown) includes a planar lower surface (one surface in the thickness direction) of the upper mold M3 shown in FIGS. 10 and 11, and a planar upper surface (one in the thickness direction) of the lower mold M5. The projections (for example, many fine projections) are formed on at least one of the surfaces.

  In the transfer unit 9B, the fibrous substrate W is heated by the heating unit, the lower surface of the upper mold M3 and the upper surface of the lower mold M3 are opposed to each other, and the fiber stretched by the substrate transfer unit 7 While maintaining the position (position in the X-axis direction) of the fibrous base material W, the fibrous base material W stretched by the molds M3 and M5 is sandwiched and pressed to perform transfer.

  When performing the transfer, the upper mold M3 is moved in one direction (Y-axis direction) orthogonal to the extending direction of the fibrous base material W, and the lower mold M5 is reversed in the Y-axis direction. It is designed to move in the direction.

  By the way, when the transfer shown in FIGS. 10 and 11 is performed, the stretched fibrous base material W may be rotated around the central axis CW in the same manner as the case shown in FIGS. . Further, the transfer unit 9B is provided with a cooling unit for cooling the fibrous base material W heated and softened by the heating unit in the same manner as the transfer unit 9A.

  The transfer unit 9B will be described in more detail.

  As shown in FIGS. 10, 11 and the like, the transfer unit 9B includes, for example, a frame 53B, a lower table 93, an upper table 95, and a moving body 97 provided inside the frame 53B. ing.

  The lower table 93 is supported by the frame 53B below the frame 53B via a linear guide bearing (not shown), and is movable with respect to the frame 53B in the Y-axis direction. Further, the lower table 93 is movable and positionable by an actuator such as a servo motor 99 under the control of the control device 39.

  The upper table 95 is supported by the frame 53B on the upper side of the frame 53B via a linear guide bearing (not shown), and is movable with respect to the frame 53B in the Y-axis direction. The upper table 95 can be moved and positioned by an actuator such as a servo motor 101 under the control of the control device 39.

  The moving body 97 is supported by the upper table 95 below the upper table 95 via a linear guide bearing (not shown), and is movable with respect to the upper table 95 in the Z-axis direction. The movable body 97 can be moved and positioned by an actuator such as a servo motor 103 under the control of the control device 39.

  An upper mold M3 is integrally installed at the lower end of the movable body 97, and a lower mold M5 is integrally installed at the upper end of the lower table 93.

  Then, by appropriately driving the servo motor 103, for example, as shown in FIGS. 10 and 11, the fibrous base material W is sandwiched between the upper mold M3 and the lower mold M5.

  With the fibrous substrate W sandwiched between the upper mold M3 and the lower mold M5 in this way, the servo motors 99 and 101 are appropriately driven to stop the movement of the fibrous substrate W in the X-axis direction. In this state, the above-described transfer is performed by the upper mold M3 and the lower mold M5.

  The transfer shown in FIGS. 10 and 11 will be described in more detail.

  First, when the upper mold M3 is lifted away from the lower mold M5, as shown in FIG. 19A, in the Y-axis direction, the upper mold M3 is separated from the fibrous base material W and has a fibrous base. The lower mold M5 is located on the left side of the fibrous base material W away from the fibrous base material W. Further, in the Z-axis direction, the upper mold M3 is separated from the fibrous base material W and positioned on the upper side of the fibrous base material W, and the lower mold M5 is separated from the fibrous base material W by a slight distance L5. It is located below the substrate W. “D1” is the diameter of the fibrous base material W.

  When the upper mold M3 is moved to the left by a predetermined distance and the lower mold M5 is moved to the right by a predetermined distance from the state shown in FIG. 19A, the state shown in FIG. 19B is obtained. In the state shown in FIG. 19B, in the Y-axis direction, the left part of the upper mold M3 is located directly above the fibrous base material W, and the right part of the lower mold M5 is the fibrous base material W. It is located directly below.

  From the state shown in FIG. 19B, the upper mold M3 is lowered, and the fibrous base material W is sandwiched between the molds M3 and M5 with a predetermined pressing force. At this time, the dimension L6 between the molds M3 and M5 is substantially equal to or slightly smaller than the diameter d1 of the fibrous base material W.

  While the fibrous base material W is sandwiched between the molds M3 and M5, the upper mold M3 is moved to the left at a predetermined speed, and the lower mold M5 is synchronized with the upper mold M3 on the right at a predetermined speed. It moves until it will be in the state shown by 19 (d). As a result, the transfer pattern formed on the molds M3 and M5 is transferred to the fibrous substrate W.

  When transfer is performed in the mode shown in FIGS. 10, 11, and 19, when the fibrous base material W may be twisted, the fibrous base material W (raw material reel) is centered on the axis CW. The rotating body 29 and the take-up reel rotating body 43) may be rotated.

  By the way, in place of or in addition to the transfer portions 9A and 9B, other modes of transfer (for example, transfer by a thermal imprint method) may be performed.

  For example, as shown in FIGS. 13 to 16, the fibrous base material W is sandwiched between the upper roller M7 and the lower mold M5 (or the lower roller M9 and the upper mold M3), and the transfer to the fibrous base material W is performed.

  In the transfer mode shown in FIGS. 15 and 16, as shown in FIG. 20B, the upper roller M7 may be rotated and moved, and the lower mold M5 may be moved for transfer. At this time, in order to prevent the fibrous substrate W from being twisted, the fibrous substrate W may be rotated about the axis CW.

  Further, in the transfer mode shown in FIGS. 15, 16, and 20A, as shown in FIG. 20C, a V groove M17 is provided in the lower mold M5, and the fibrous base material W is provided in the V groove W17. It is also possible to transfer by inserting the

  In addition, as shown in FIG. 21, the fibrous base material W may be sandwiched between the upper mold M3 and the lower mold M5, and the small-diameter portion W7 may be formed in the fibrous base material W.

  Furthermore, as shown in FIG. 22, the upper mold M3 and the lower mold M5 are provided with convex portions M19, the upper mold M3 and the lower mold M5 are moved, and the small diameter of the fibrous base material W is moved by each convex portion M19. The part W7 may be formed.
