[0010] [First embodiment] Hereinafter, the shaping device 100 according to the first embodiment of the present disclosure and the shaping method using the same will be described with reference to the drawings. FIG. 1 is a perspective view showing the shaping device 100 according to the first embodiment of the present disclosure, showing a state after the shaping operation is performed. FIG. 2 is a front view showing the shaping device 100 according to the first embodiment of the present disclosure, showing a state before the shaping operation is performed. FIG. 3 is a front view showing the shaping device according to the first embodiment of the present disclosure, showing a state after the shaping operation is performed. FIG. 4 is an exploded view of the shaping device shown in FIG. 2.

[0011] The shaping device 100 of this embodiment is a device that shapes a laminate 200 formed by stacking a plurality of sheet materials including reinforcing fibers along the surface shape of a shaping mold 10. The laminate 200 is formed by stacking a plurality of sheet-like layers of composite material. The composite material constituting the laminate 200 is a sheet-like intermediate molding material that is semi-integrated by attaching a matrix resin to reinforcing fibers.

[0012] The reinforcing fibers contained in the composite material are, for example, carbon fibers, glass fibers, aramid fibers, etc. The matrix resin contained in the composite material can be a thermosetting resin or a thermoplastic resin. Examples of the thermosetting matrix resin include epoxy resin, unsaturated polyester, vinyl ester, phenol, cyanate ester, polyimide, etc.

[0013] Examples of thermoplastic matrix resins include polyether ether ketone (PEEK), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), nylon 6 (PA6), nylon 66 (PA66), polyphenylene sulfide (PPS), polyetherimide (PEI), polyether ketone ketone (PEKK), and the like.

[0014] The shaping mold 10 is provided with a heating mechanism (not shown) capable of heating the matrix resin to a temperature equal to or higher than the softening temperature. By heating the matrix resin to a temperature equal to or higher than the softening temperature by the heating mechanism, the laminate 200 containing the matrix resin can be shaped to conform to the surface shape of the shaping mold 10.

[0015] A flat laminate of a plurality of sheet-like reinforcing fibers (dry fabric) not including a matrix resin may be used as the laminate 200. When using a dry fabric, the laminate 200 shaped according to the surface shape of the shaping mold 10 is placed in a molding die (not shown), and a resin material is injected into the molding die to impregnate the reinforcing fibers and form the laminate 200, which is called an RTM (Resin Transfer Molding) method.

[0016] In the laminate 200 formed by the dry fabric, it is preferable to sprinkle a powdered resin (powder binder) on the surface of each of the multiple dry fabric layers to temporarily bond adjacent dry fabrics together. As the powder binder, a thermosetting resin or a thermoplastic resin can be used.

[0017] As shown in FIG. 1, the shaping apparatus 100 of this embodiment includes a shaping mold 10, a rotating mechanism 20, a first shaping sheet 30, a second shaping sheet 40, a shape-retaining sheet 50, fixing bars 61, 62, 63, a load cell (first detection unit) 70, a load cell 80, and a control device 90.

[0018] The shaping mold 10 is a mold having a surface shape for shaping the laminate 200, and is formed of, for example, a metal material. As shown in Fig. 2, the shaping mold 10 has a first shaping member 11 that contacts a first surface 201 of the laminate 200, a second shaping member 12 that contacts a second surface 202 of the laminate 200, a holding member 13, and a holding member 14. The holding member 13 and the holding member 14 are members that hold the state in which the first region R1 of the laminate 200 is sandwiched between the first shaping member 11 and the second shaping member 12 and arranged along the width direction (predetermined direction).

[0019] As shown in Fig. 4, the laminate 200 has a first region R1 in the center in the width direction WD, a second region R2 on the end side of the width direction WD adjacent to the first region R1, and a third region R3 on the end side of the width direction WD adjacent to the first region R1. The laminate 200 is formed by laminating six reinforcing fiber sheets 200a, 200b, 200c, 200d, 200e, and 200f along a thickness direction TD perpendicular to the width direction WD. The number of reinforcing fiber sheets constituting the laminate 200 may be any number other than six.

[0020] 4, the first shaping member 11 has a first contact surface 11a extending along the width direction WD in contact with the first region R1 of the laminate 200, and a first shaping surface 11b inclined at a first predetermined angle θ1 with respect to the width direction WD. The first predetermined angle θ1 is set in the range of, for example, 45 degrees or more and 120 degrees or less.

[0021] 4, the second shaping member 12 has a second contact surface 12a that contacts the first region R1 of the laminate 200 and extends along the width direction WD, and a second shaping surface 12b that is inclined at a second predetermined angle θ2 with respect to the width direction WD. The second predetermined angle θ2 is set in the range of, for example, 45 degrees or more and 120 degrees or less.

[0022] The rotation mechanism 20 is a mechanism for rotating the shaping mold 10 around a rotation axis X perpendicular to the width direction WD. As shown in FIG. 1, the rotation mechanism 20 includes a drive motor 21, a reducer 22, a support shaft 23, a support table 24, and a support table 25. The support table 24 and the support table 25 are disposed near both ends of the longitudinal direction LD in which the laminate 200 extends, and are members that support the holding members 13 and 14 of the shaping mold 10 rotatably around the rotation axis X via the support shaft 23. The drive motor 21 rotates the shaping mold 10 around the rotation axis X via the reducer 22 and the support shaft 23 connected to the reducer.

[0023] The rotation mechanism 20 rotates the shaping mold 10 clockwise around the rotation axis X, thereby performing a shaping operation in which the first shaping sheet 30 in contact with the second surface 202 of the laminate 200 is pressed against the first shaping surface 11b to fold the laminate 200. The rotation mechanism 20 also rotates the shaping mold 10 clockwise around the rotation axis X, thereby performing a shaping operation in which the second shaping sheet 40 in contact with the first surface 201 of the laminate 200 is pressed against the second shaping surface 12b to fold the laminate 200.

[0024] As shown in FIG. 2, before the rotating mechanism 20 performs the shaping operation, the first region R1 of the laminate 200 is sandwiched between the first shaping member 11 and the second shaping member 12 and is held by the holding member 13 in a state arranged along the width direction WD. The first surface 201 of the second region R2 of the laminate 200 is held by the shape-retaining sheet 50 so as not to contact the first shaping surface 11b. The first surface 201 of the third region R3 of the laminate 200 is supported by the first shaping member 11 via the second shaping sheet 40. The rotating mechanism 20 rotates the shaping mold 10 about 90 degrees clockwise around the rotation axis X from the state shown in FIG. 2 to the state shown in FIG. 3.

[0025] 3, in a state after the rotating mechanism 20 executes the shaping operation, tension is applied to the second region R2 of the laminate 200 from the first shaping sheet 30 in contact with the second surface 202, and the first surface 201 is pressed against the first shaping surface 11b via the shape-retaining sheet 50. Similarly, tension is applied to the third region R3 of the laminate 200 from the second shaping sheet 40 in contact with the first surface 201, and the second surface 202 is pressed against the second shaping surface 12b.

[0026] The first shaping sheet 30 is a sheet for shaping the second region R2 of the laminate 200. The first shaping sheet 30 is formed of, for example, a rubber material having elasticity that is stretchable along the width direction WD. One end 30a of the first shaping sheet 30 is fixed to the second shaping member 12 at a position facing the second region R2 of the laminate 200. The other end 30b of the first shaping sheet 30 is fixed to the first predetermined position P1 of the first wall portion WA1 via a fixing bar 61, a load cell 70, and a connecting cable 71.

[0027] The second shaping sheet 40 is a sheet for shaping the third region R3 of the laminate 200. The second shaping sheet 40 is formed of, for example, a rubber material having elasticity that is stretchable along the width direction WD. One end 40a of the second shaping sheet 40 is fixed to the first shaping member 11 at a position facing the third region R3 of the laminate 200. The other end 40b of the second shaping sheet 40 is fixed to the second predetermined position P2 of the second wall portion WA2 via the fixing bar 62, the load cell 80, and the connecting cable 81.

[0028] The shape-retaining sheet 50 is a sheet for retaining the shape of the second region R2 of the laminate 200. The shape-retaining sheet 50 is formed of, for example, a rubber material having elasticity that allows it to stretch along the width direction WD. One end 50a of the shape-retaining sheet 50 is fixed to the first shaping member 11 at a position facing the second region R2 of the laminate 200. The other end 50b of the shape-retaining sheet 50 is fixed to the third predetermined position P3 of the first wall portion WA1 via a fixing bar 63 and a connecting cable 64.

[0029] 2, before the rotating mechanism 20 performs the shaping operation, the shaping mold 10 holds the first region of the laminate 200 between the first shaping member 11 and the second shaping member 12 with the width direction WD aligned horizontally. In addition, the shape-retaining sheet 50 holds the first surface 201 of the laminate 200 so that the second region R2 of the laminate 200 does not come into contact with the first shaping surface 11b.

[0030] The fixed bar 61 is an axial member attached to the other end 30b of the first shaped sheet 30 and extending along the longitudinal direction LD. The fixed bar 61 is fixed to a first predetermined position P1 of the first wall portion WA1 via a load cell 70 and a connecting cable 71. The fixed bar 62 is an axial member attached to the other end 40b of the second shaped sheet 40 and extending along the longitudinal direction LD. The fixed bar 62 is fixed to a second predetermined position P2 of the second wall portion WA2 via a load cell 80 and a connecting cable 81. The fixed bar 63 is an axial member attached to the other end 50b of the shape-retaining sheet 50 and extending along the longitudinal direction LD. The fixed bar 63 is fixed to a third predetermined position P3 of the first wall portion WA1 via a connecting cable 64.

[0031] The load cell (first detection unit) 70 is a device that detects a first tension applied to the first shaping sheet 30 when the rotating mechanism 20 executes the shaping operation. The first tension detected by the load cell 70 is transmitted to the control device 90. The load cell (second detection unit) 80 is a device that detects the second tension applied to the second shaping sheet 40 when the rotating mechanism 20 executes the shaping operation. The second tension detected by the load cell 80 is transmitted to the control device 90.

[0032] The control device 90 is a device that controls each part of the shaping device 100 including the rotation mechanism 20. The control device 90 executes an operation of controlling each part according to a program stored in a storage unit (not shown).

[0033] Next, a description will be given of a shaping method executed by the shaping apparatus 100 of this embodiment. Fig. 5 is a flowchart showing the shaping method executed by the shaping apparatus 100 according to the first embodiment of the present disclosure.

[0034] In step S101, the worker places the laminate 200 in the shaping mold 10. The worker aligns the width direction WD of the laminate 200 with the horizontal direction to hold the first region R1 of the laminate 200 between the first shaping member 11 and the second shaping member 12. The worker attaches holding members 13 to both ends of the longitudinal direction LD of the shaping mold 10 so as to maintain the state in which the laminate 200 is held between the first shaping member 11 and the second shaping member 12.

[0035] In step S102, the worker fixes the first shaping sheet 30 and the second shaping sheet 40 to the first predetermined position P1 and the second predetermined position P2, respectively. The worker fixes the other end 30b of the first shaping sheet 30 to the first predetermined position P1 via the fixing bar 61, the load cell 70, and the connecting cable 71. The worker also fixes the other end 40b of the second shaping sheet 40 to the second predetermined position P2 via the fixing bar 62, the load cell 80, and the connecting cable 81.

[0036] In step S103, the worker fixes the shape-retaining sheet 50 to the third predetermined position P3. The worker fixes the other end 50b of the shape-retaining sheet 50 to the third predetermined position P3 via the fixing bar 63 and the connecting cable 64. When steps S101 to S103 described above are performed, the shaping device 100 is in the state shown in FIG.

[0037] In step S104, the control device 90 controls the rotation mechanism 20 to start rotation of the shaping mold 10. The control device 90 starts the operation of the drive motor 21 of the rotation mechanism 20, and starts the operation of rotating the shaping mold 10 clockwise around the rotation axis X.

[0038] In step S105, the control device 90 judges whether the first tension output from the load cell 70 is equal to or greater than the first predetermined tension, and if YES, the process proceeds to step S106, and if NO, step S105 is executed again. The first predetermined tension is a tension that is preset so that the first shaping sheet 30 can apply a load necessary for pressing the second region R2 of the laminate 200 against the first shaping surface 11b of the first shaping member 11.

[0039] In step S106, the control device 90 judges whether the second tension output from the load cell 80 is equal to or greater than the second predetermined tension, and if YES, the process proceeds to step S107, and if NO, step S106 is executed again. The second predetermined tension is a tension that is preset so that the second shaping sheet 40 can apply a load necessary for pressing the third region R3 of the laminate 200 against the second shaping surface 12b of the second shaping member 12.

[0040] In step S107, since the first tension output from the load cell 70 is equal to or greater than the first predetermined tension and the second tension output from the load cell 80 is equal to or greater than the second predetermined tension, the control device 90 controls the rotation mechanism 20 to stop the rotation of the shaping mold 10. The rotation mechanism 20 stops the rotation of the shaping mold 10 in response to the first tension detected by the load cell 70 reaching the first predetermined tension and the second tension detected by the load cell 80 reaching the second predetermined tension.

[0041] In step S108, a shaping completion step is executed. The worker releases the other end 30b of the first shaping sheet 30 from the first predetermined position P1, releases the other end 40b of the second shaping sheet 40 from the second predetermined position P2, and releases the other end 50b of the shape-retaining sheet 50 from the third predetermined position P3. The worker also removes the laminate 200, in which the shaping operation (operations from step S104 to step S107) has been executed and the first region R1 and the third region R3 have been folded, from the shaping mold 10. With the above processing, the shaping method executed by the shaping device 100 is completed.

[0042] In the above flow chart, the control device 90 controls the rotation mechanism 20 to stop the rotation of the shaping mold 10 because the first tension output from the load cell 70 is equal to or greater than the first predetermined tension and the second tension output from the load cell 80 is equal to or greater than the second predetermined tension, but other embodiments may be used. For example, the control device 90 may control the rotation mechanism 20 to stop the rotation of the shaping mold 10 when the first tension output from the load cell 70 is equal to or greater than the first predetermined tension. That is, the control device 90 may control the rotation mechanism 20 to stop the rotation of the shaping mold 10 by referring only to the first tension detected by the load cell 70. Furthermore, the control device 90 may control the rotation mechanism 20 to stop the rotation of the shaping mold 10 by referring only to the second tension detected by the load cell 80.

[0043] The actions and effects of the shaping apparatus 100 of the present embodiment described above will be described. According to the shaping device 100 of this embodiment, the first region R1 of the laminate 200 is held by the holding member 13 in a state in which it is sandwiched between the first shaping member 11 and the second shaping member 12 and arranged along the width direction WD. The rotating mechanism 20 rotates the shaping mold 10 around the rotation axis X, thereby performing a shaping operation in which the first surface 201 of the laminate 200 is pressed against the first shaping surface 11b by the first shaping sheet 30 in contact with the second surface 202 of the laminate 200, thereby folding the laminate 200.

[0044] The first shaping sheet 30 has one end 30a fixed to the second shaping member 12 at a position facing the second region R2 adjacent to the first region R1, and the other end 30b fixed to the first predetermined position P1. Therefore, when the shaping mold 10 is rotated around the rotation axis X by the rotation mechanism 20, the first shaping sheet 30 is pressed against the second surface 202 of the laminate 200, and the first surface 201 of the laminate 200 is pressed against the first shaping surface 11b of the first shaping member 11. Since the first shaping surface 11b is inclined at a first predetermined angle θ1 with respect to the width direction WD, the second region R2 of the laminate 200 is folded at the first predetermined angle θ1 by the shaping operation. This allows the laminate 200 to be folded faithfully along the shape of the shaping mold 10.

[0045] According to the shaping device 100 of this embodiment, the rotation mechanism 20 rotates the shaping mold 10 around the rotation axis X, thereby performing a shaping operation in which the second shaping sheet 40, which is in contact with the first surface 201 of the laminate 200, presses the second surface 202 of the laminate 200 against the second shaping surface 12b, thereby folding the laminate 200.

[0046] The second shaping sheet 40 has one end 40a fixed to the first shaping member 11 at a position facing the third region R3 adjacent to the first region R1, and the other end 40b fixed to the second predetermined position P2. Therefore, when the shaping mold 10 is rotated around the rotation axis X by the rotation mechanism 20, the second shaping sheet 40 is pressed against the first surface 201 of the laminate 200, and the second surface 202 of the laminate 200 is pressed against the second shaping surface 12b of the second shaping member 12. Since the second shaping surface 12b is inclined at the second predetermined angle θ2 with respect to the width direction WD, the third region R3 of the laminate 200 is folded at the second predetermined angle θ2 by the shaping operation.

[0047] According to the shaping device 100 of this embodiment, before the rotating mechanism 20 performs the shaping operation, the shaping mold 10 holds the first region R1 of the laminate 200 between the first shaping member 11 and the second shaping member 12 with the width direction WD aligned horizontally. Since the first region R1 of the laminate 200 is held horizontally, the second region R2 adjacent to the first region R1 is subjected to downward gravity. Therefore, the shape-retaining sheet 50 holds the first surface 201 of the laminate 200 so as not to come into contact with the first shaping surface 11b, thereby appropriately preventing the second region R2 of the laminate 200 from being deformed by the weight.

[0048] According to the shaping device 100 of this embodiment, when the first tension applied to the first shaping sheet 30 reaches a first predetermined tension, the rotation of the shaping mold 10 is stopped, thereby making it possible to appropriately maintain the state in which the first shaping sheet 30 applies the first predetermined tension to the laminate 200.

[0049] Second Embodiment Next, a shaping apparatus 100A according to a second embodiment of the present disclosure will be described with reference to the drawings. This embodiment is a modified example of the first embodiment, and is the same as the first embodiment except as described below, and the description thereof will be omitted below.

[0050] The shaping device 100 of the first embodiment fixes the other end 30b of the first shaping sheet 30 and the other end 40b of the second shaping sheet 40, and rotates the shaping mold 10 holding the laminate 200 around the rotation axis X, thereby performing a shaping operation to fold the second region R2 and the third region R3 of the laminate 200 relative to the first region R1.

[0051] In contrast, the shaping device 100A of this embodiment fixes the shaping mold 10 holding the laminate 200 without rotating it, and moves the other end 30b of the first shaping sheet 30 and the other end 40b of the second shaping sheet 40 around the rotation axis X by the moving mechanism 20A, thereby performing a shaping operation to fold the second region R2 and the third region R3 of the laminate 200 relative to the first region R1.

[0052] Fig. 6 is a front view of the shaping device 100A according to the second embodiment of the present disclosure, showing a state before the shaping operation is performed. Fig. 7 is a front view of the shaping device 100A according to the second embodiment of the present disclosure, showing a state after the shaping operation is performed.

[0053] The moving mechanism 20A is a mechanism having a first moving section 20A1 that moves the other end 30b of the first shaping sheet 30 and a second moving section 20A2 that moves the other end 40b of the second shaping sheet 40.

[0054] The first moving section 20A1 performs a shaping operation in which the first shaping sheet 30 contacting the second surface 202 of the laminate 200 presses the first surface 201 of the laminate 200 against the first shaping surface 11b by moving the other end 30b of the first shaping sheet 30 counterclockwise around the rotation axis X, thereby folding the laminate 200. In addition, the second moving section 20A2 performs a shaping operation in which the second shaping sheet 40 contacting the first surface 201 of the laminate 200 presses the second surface 202 of the laminate 200 against the second shaping surface 12b by moving the other end 30b of the second shaping sheet 40 counterclockwise around the rotation axis X, thereby folding the laminate 200.

[0055] As shown in FIG. 6, before the moving mechanism 20A performs the shaping operation, the first region R1 of the laminate 200 is sandwiched between the first shaping member 11 and the second shaping member 12 and is held by the holding member 13 in a state arranged along the width direction WD. The first surface 201 of the second region R2 of the laminate 200 is held by the shape-retaining sheet 50 so as not to contact the first shaping surface 11b. The first surface 201 of the third region R3 of the laminate 200 is supported by the first shaping member 11 via the second shaping sheet 40. The moving mechanism 20A moves the other end 30b of the first shaping sheet 30 and the other end 40b of the second shaping sheet 40 about 90 degrees counterclockwise around the rotation axis X from the state shown in FIG. 6 to the state shown in FIG. 7.

[0056] 7, in a state after the moving mechanism 20A executes the shaping operation, tension is applied to the second region R2 of the laminate 200 from the first shaping sheet 30 in contact with the second surface 202, and the first surface 201 is pressed against the first shaping surface 11b via the shape-retaining sheet 50. Similarly, tension is applied to the third region R3 of the laminate 200 from the second shaping sheet 40 in contact with the first surface 201, and the second surface 202 is pressed against the second shaping surface 12b.

[0057] According to the shaping device 100A of this embodiment, the first region R1 of the laminate 200 is held by the holding member 13 in a state in which it is sandwiched between the first shaping member 11 and the second shaping member 12 and arranged along the width direction WD. The moving mechanism 20A moves the other end 30b of the first shaping sheet 30 in contact with the second surface 202 of the laminate 200, thereby performing a shaping operation in which the first shaping sheet 30 in contact with the second surface 202 of the laminate 200 presses the first surface 201 of the laminate 200 against the first shaping surface 11b to fold the laminate 200.

[0058] The first shaping sheet 30 has one end 30a fixed to the second shaping member 12 at a position facing the second region R2 adjacent to the first region R1 of the laminate 200. Therefore, when the other end 30b of the first shaping sheet 30 is moved by the moving mechanism 20A, the first shaping sheet 30 is pressed against the second surface 202 of the laminate 200, and the first surface 201 of the laminate 200 is pressed against the first shaping surface 11b of the first shaping member 11. Since the first shaping surface 11b is inclined at a first predetermined angle θ1 with respect to the width direction WD, the second region R2 of the laminate 200 is folded at the first predetermined angle θ1 by the shaping operation. This allows the laminate 200 to be folded faithfully along the shape of the shaping mold 10.

[0059] The moving mechanism 20A moves the other end 40b of the second shaping sheet 40 that is in contact with the first surface 201 of the laminate 200, thereby performing a shaping operation in which the second shaping sheet 40 that is in contact with the first surface 201 of the laminate 200 presses the second surface 202 of the laminate 200 against the second shaping surface 12b to fold the laminate 200.

[0060] The second shaping sheet 40 has one end 40a fixed to the first shaping member 11 at a position facing the third region R3 adjacent to the first region R1 of the laminate 200. Therefore, when the other end 40b of the second shaping sheet 40 is moved by the moving mechanism 20A, the second shaping sheet 40 is pressed against the first surface 201 of the laminate 200, and the second surface 202 of the laminate 200 is pressed against the second shaping surface 12b of the second shaping member 12. Since the second shaping surface 12b is inclined at a second predetermined angle θ2 with respect to the width direction WD, the third region R3 of the laminate 200 is folded at the second predetermined angle θ2 by the shaping operation. This allows the laminate 200 to be folded faithfully along the shape of the shaping mold 10.

[0061] Third Embodiment Next, a shaping apparatus 100B according to a third embodiment of the present disclosure will be described with reference to the drawings. This embodiment is a modified example of the first embodiment, and is the same as the first embodiment except as described below, and the description thereof will be omitted below.

[0062] The shaping device 100 of the first embodiment includes a load cell 70 that detects a first tension applied to the first shaping sheet 30, and a load cell 80 that detects a second tension applied to the second shaping sheet 40. The shaping device 100 of the first embodiment controls the rotation mechanism 20 to stop the rotation of the shaping mold 10 when the first tension output from the load cell 70 is equal to or greater than a first predetermined tension and the second tension output from the load cell 80 is equal to or greater than a second predetermined tension.

[0063] In contrast, the shaping device 100B of this embodiment does not include the load cell 70 and the load cell 80. The shaping device 100B of this embodiment controls the rotation mechanism 20 to stop the rotation of the shaping mold 10 when the rotation angle θ3 of the shaping mold 10 about the rotation axis X from the state in which the laminate 200 is placed on the shaping mold 10 is equal to or greater than a predetermined stop angle.

[0064] Fig. 8 is a front view showing the shaping device 100B according to the third embodiment of the present disclosure, showing a state before the shaping operation is performed. Fig. 9 is a front view showing the shaping device 100B according to the third embodiment of the present disclosure, showing a state after the shaping operation is performed.

[0065] The shaping apparatus 100B of this embodiment is similar to the shaping apparatus 100 of the first embodiment, except that it does not include the load cell 70 and the load cell 80. In Fig. 8 and Fig. 9, the axis Y is an axis parallel to the width direction WD. The axis Z is an axis along the direction in which the flat first region R1 of the laminate 200 extends. As shown in Fig. 8, the axis Z coincides with the axis Y around the rotation axis X before the shaping operation is performed.

[0066] 9, the axis Z is disposed at a rotation angle θ3 from the axis Y in the rotation direction around the rotation axis X after the shaping operation is performed. The shaping device 100B of this embodiment adjusts the rotation angle θ3 after the shaping operation is performed so that the first tension applied to the first shaping sheet 30 and the second tension applied to the second shaping sheet 40 have desired values.

[0067] Next, a shaping method executed by the shaping device 100B of this embodiment will be described. Fig. 10 is a flowchart showing a shaping method executed by the shaping device 100B according to the third embodiment of the present disclosure. Steps S201-S204 and steps S206-207 in the flowchart shown in Fig. 10 are similar to steps S101-S104 and steps S107-108 in the flowchart shown in Fig. 5 of the first embodiment, and therefore will not be described below.

[0068] In step S205, the control device 90 judges whether the rotation angle θ3 of the axis Z around the rotation axis X relative to the axis Y is equal to or greater than a predetermined stop angle θs, and if YES, the process proceeds to step S206, and if NO, the judgment of step S205 is repeated. The predetermined stop angle θs is set to an angle at which the first shaping sheet 30 is given a first predetermined tension or more, and the second shaping sheet 40 is given a second predetermined tension or more. The predetermined stop angle θs is set, for example, in the range of 45 degrees or more and 120 degrees or less.

[0069] The predetermined stop angle θs may be set to a constant value that does not change, but may be set in other ways. For example, the predetermined stop angle θs may be set to increase according to the number of times the shaping operation using the first shaping sheet 30 and the second shaping sheet 40 is performed. Since the first shaping sheet 30 and the second shaping sheet 40 are made of a rubber material, the elastic force decreases due to repeated load caused by the increase in the number of times the shaping operation is performed. By increasing the predetermined stop angle θs according to the number of times the shaping operation is performed, even if the elastic force of the first shaping sheet 30 and the second shaping sheet 40 decreases, it is possible to maintain a state in which the first predetermined tension or more is applied to the first shaping sheet 30 and the second predetermined tension or more is applied to the second shaping sheet 40 after the shaping operation is performed.

[0070] Here, the first predetermined tension is a tension that is preset so that the first shaping sheet 30 can apply a load required to press the second region R2 of the laminate 200 against the first shaping surface 11b of the first shaping member 11. The second predetermined tension is a tension that is preset so that the second shaping sheet 40 can apply a load required to press the third region R3 of the laminate 200 against the second shaping surface 12b of the second shaping member 12.

[0071] In step S205, the control device 90 detects the rotation angle θ3, for example, from a signal output from an angle detection mechanism (not shown) provided in the rotation mechanism 20. The control device 90 may also detect the rotation angle θ3 from the elapsed time since the start of rotation of the shaping mold 10 in step S204, the number of pulses of the drive signal transmitted to the rotation mechanism 20, or the like.

[0072] In step S206, since the rotation angle θ3 of the shaping mold 10 about the rotation axis X is equal to or greater than the predetermined stop angle θs, the control device 90 controls the rotation mechanism 20 to stop the rotation of the shaping mold 10. The rotation mechanism 20 stops the rotation of the shaping mold 10 in response to the rotation angle θ3 of the shaping mold 10 about the rotation axis X reaching the predetermined stop angle θs.

[0073] According to the shaping device 100B of this embodiment, when the rotation angle θ3 of the shaping mold 10 around the rotation axis X reaches a predetermined stop angle θs, the rotation of the shaping mold 10 is stopped, thereby appropriately maintaining a state in which the first shaping sheet 30 applies a desired load to the second region R2 of the laminate 200 and the second shaping sheet 40 applies a desired load to the third region R3 of the laminate 200.

[0074] The shaping device and the shaping method according to the above-described embodiments can be understood, for example, as follows. The shaping device according to the first aspect of the present disclosure is a shaping device (100) for shaping a laminate (200) obtained by stacking a plurality of sheet materials including reinforcing fibers, the shaping device including a shaping mold (10) having a first shaping member (11) contacting a first surface (201) of the laminate, a second shaping member (12) contacting a second surface (202) of the laminate, and a holding member (13) for holding the laminate between the first shaping member and the second shaping member such that a first region (R1) of the laminate is arranged along a predetermined direction (WD), a rotation mechanism (20) for rotating the shaping mold around a rotation axis (X) perpendicular to the predetermined direction, and a holding member (13) for holding the first region (R1) of the laminate in a state in which the first region (R1) is arranged along a predetermined direction (WD). and a first shaping sheet (30) having one end fixed to the second shaping member at a position facing a second region (R2) of the laminate and the other end fixed to a first predetermined position, the first shaping member having a first contact surface (11a) contacting the first region of the laminate and extending along the predetermined direction, and a first shaping surface (11b) inclined at a first predetermined angle (θ1) with respect to the predetermined direction, and the rotation mechanism rotates the shaping mold around the rotation axis, thereby performing a shaping operation in which the first shaping sheet contacting the first surface of the laminate presses the second surface of the laminate against the first shaping surface to fold the laminate.

[0075] According to the shaping device of the first aspect of the present disclosure, a first region of a laminate formed by stacking a plurality of sheet materials including reinforcing fibers is sandwiched between a first shaping member and a second shaping member and held in a state arranged along a predetermined direction by a holding member. The rotating mechanism rotates the shaping mold around the rotation axis, thereby performing a shaping operation in which the first surface of the laminate is pressed against the first shaping surface by the first shaping sheet contacting the second surface of the laminate, thereby folding the laminate.

[0076] The first shaping sheet has one end fixed to the second shaping member at a position facing the second region adjacent to the first region, and the other end fixed to a first predetermined position. Therefore, when the shaping mold is rotated around the rotation axis by the rotation mechanism, the first shaping sheet is pressed against the second surface of the laminate, and the first surface of the laminate is pressed against the first shaping surface of the first shaping member. Since the first shaping surface is inclined at a first predetermined angle with respect to the predetermined direction, the second region of the laminate is folded at the first predetermined angle by the shaping operation. This makes it possible to provide a shaping device that can faithfully fold the laminate along the shape of the shaping mold.

[0077] The shaping device according to the second aspect of the present disclosure further includes the following configuration in the first aspect: Namely, the shaping device includes a second shaping sheet (40) having one end fixed to a first shaping member at a position facing a third region adjacent to the first region and the other end fixed to a second predetermined position, the second shaping member has a second contact surface (12a) contacting the first region of the laminate and extending along the predetermined direction, and a second shaping surface (12b) inclined at a second predetermined angle (θ2) with respect to the predetermined direction, and the rotating mechanism rotates the shaping mold around the rotation axis, thereby pressing the second surface of the laminate against the second shaping surface with the second shaping sheet contacting the first surface of the laminate, thereby performing the shaping operation of folding the laminate.

[0078] According to the shaping device of the second aspect of the present disclosure, the rotation mechanism rotates the shaping mold around the rotation axis, thereby performing a shaping operation in which the second surface of the laminate is pressed against the second shaping surface by the second shaping sheet in contact with the first surface of the laminate, thereby folding the laminate.

[0079] The second shaping sheet has one end fixed to the first shaping member at a position facing the third region adjacent to the first region, and the other end fixed to a second predetermined position. Therefore, when the shaping mold is rotated around the rotation axis by the rotation mechanism, the second shaping sheet is pressed against the first surface of the laminate, and the second surface of the laminate is pressed against the second shaping surface of the second shaping member. Since the second shaping surface is inclined at a second predetermined angle with respect to the predetermined direction, the third region of the laminate is folded at the second predetermined angle by the shaping operation.

[0080] The shaping device according to the third aspect of the present disclosure is the shape-retaining sheet (50) having one end fixed to the first shaping member at a position facing the second region and the other end fixed to a third predetermined position in the first or second aspect. )of Before the rotating mechanism performs the shaping operation, the shaping mold holds the first region of the laminate between the first shaping member and the second shaping member by aligning the predetermined direction with a horizontal direction, and the shape-retaining sheet holds the first surface of the laminate so that the second region of the laminate does not contact the first shaping surface.

[0081] According to the shaping device according to the third aspect of the present disclosure, before the rotating mechanism executes the shaping operation, the shaping mold holds the first region of the laminate between the first shaping member and the second shaping member with the predetermined direction aligned with the horizontal direction. Since the first region of the laminate is held in the horizontal direction, the second region adjacent to the first region is subjected to a downward gravity force. Therefore, the shape-retaining sheet holds the first surface of the laminate so as not to come into contact with the first shaping surface, thereby appropriately preventing the second region of the laminate from being deformed by the weight.

[0082] The shaping device according to the fourth aspect of the present disclosure, in the first or second aspect, is provided with a first detection unit (70) that detects a first tension applied to the first shaping sheet when the rotation mechanism performs the shaping operation, and the rotation mechanism stops the rotation of the shaping mold in response to the first tension detected by the first detection unit reaching a first predetermined tension.

[0083] According to the shaping device of the fourth aspect of the present disclosure, when the first tension applied to the first shaping sheet reaches a first predetermined tension, the rotation of the shaping mold is stopped, thereby appropriately maintaining the state in which the first shaping sheet applies the first predetermined tension to the laminate.

[0084] In the second aspect, the shaping device according to the fifth aspect of the present disclosure includes a first detection unit that detects a first tension applied to the first shaping sheet when the rotation mechanism performs the shaping operation, and a second detection unit that detects a second tension applied to the second shaping sheet when the rotation mechanism performs the shaping operation, and the rotation mechanism stops rotation of the shaping mold in response to the first tension detected by the first detection unit reaching a first predetermined tension and the second tension detected by the second detection unit reaching a second predetermined tension.

[0085] According to the shaping device of the fifth aspect of the present disclosure, when the first tension applied to the first shaping sheet reaches a first predetermined tension and the second tension applied to the second shaping sheet reaches a second predetermined tension, the rotation of the shaping mold is stopped, thereby making it possible to appropriately maintain a state in which the first shaping sheet applies the first predetermined tension to the laminate and the second shaping sheet applies the second predetermined tension to the laminate.

[0086] In the shaping device according to the sixth aspect of the present disclosure, in the first or second aspect, the rotation mechanism stops the rotation of the shaping mold when the rotation angle of the shaping mold around the rotation axis reaches a predetermined stop angle.

[0087] According to the shaping device of the sixth aspect of the present disclosure, the rotation of the shaping mold is stopped when the rotation angle of the shaping mold about the rotation axis thereof reaches a predetermined stop angle, thereby making it possible to appropriately maintain the state in which the first shaping sheet applies the desired load to the laminate.

[0088] A shaping device according to a seventh aspect of the present disclosure is a shaping device for shaping a laminate obtained by stacking a plurality of sheet materials including reinforcing fibers, and includes a shaping mold having a first shaping member in contact with a first surface of the laminate, a second shaping member in contact with a second surface of the laminate, and a holding member for holding a state in which a first region of the laminate is sandwiched between the first shaping member and the second shaping member and arranged along a predetermined direction, and a first shaping sheet having one end fixed to the second shaping member at a position facing a second region adjacent to the first region. The first shaping member has a first contact surface that contacts the first region of the laminate and extends along the predetermined direction, and a first shaping surface that is inclined at a first predetermined angle (θ1) with respect to the predetermined direction, and the moving mechanism performs a shaping operation of pressing the first surface of the laminate against the first shaping surface by moving the other end of the first shaping sheet that contacts the second surface of the laminate, thereby folding the laminate.

The moving mechanism performs a shaping operation in which the first shaping sheet contacting the second surface of the laminate presses the first surface of the laminate against the first shaping surface by moving the other end of the first shaping sheet contacting the second surface of the laminate, thereby folding the laminate.

[0090] The first shaping sheet has one end fixed to the second shaping member at a position facing the second region adjacent to the first region of the laminate. Therefore, when the other end of the first shaping sheet is moved by the moving mechanism, the first shaping sheet is pressed against the second surface of the laminate, and the first surface of the laminate is pressed against the first shaping surface of the first shaping member. Since the first shaping surface is inclined at a first predetermined angle with respect to the predetermined direction, the second region of the laminate is folded at the first predetermined angle by the shaping operation. This makes it possible to provide a shaping device that can faithfully fold the laminate along the shape of the shaping mold.

[0092] According to the shaping method of the eighth aspect of the present disclosure, a first region of a laminate formed by stacking a plurality of sheet materials including reinforcing fibers is sandwiched between a first shaping member and a second shaping member and is held by a holding member in a state arranged along a predetermined direction. The shaping step rotates the shaping mold around the rotation axis to perform a shaping operation in which the first surface of the laminate is pressed against the first shaping surface by the first shaping sheet contacting the second surface of the laminate, thereby folding the laminate.

[0093] The first shaping sheet has one end fixed to the second shaping member at a position facing the second region adjacent to the first region of the laminate, and the other end fixed to a first predetermined position. Therefore, when the shaping mold is rotated around the rotation axis by the rotation mechanism, the first shaping sheet is pressed against the second surface of the laminate, and the first surface of the laminate is pressed against the first shaping surface of the first shaping member. Since the first shaping surface is inclined at a first predetermined angle with respect to the predetermined direction, the second region of the laminate is folded at the first predetermined angle by the shaping operation.

[0096] The second shaping sheet has one end fixed to the first shaping member of the laminate at a position facing the third region adjacent to the first region of the laminate, and the other end fixed to a second predetermined position. Therefore, when the shaping mold is rotated around the rotation axis by the rotation mechanism, the second shaping sheet is pressed against the first surface of the laminate, and the second surface of the laminate is pressed against the second shaping surface of the second shaping member. Since the second shaping surface is inclined at a second predetermined angle with respect to the predetermined direction, the third region of the laminate is folded at the second predetermined angle by the shaping operation.

[0098] According to the shaping method according to the tenth aspect of the present disclosure, before the shaping step performs the shaping operation, the holding step holds the first region of the laminate between the first shaping member and the second shaping member by aligning the predetermined direction with the horizontal direction using the shaping mold. Since the first region of the laminate is held in the horizontal direction, the second region adjacent to the first region is subjected to downward gravity. Therefore, the shape-retaining sheet holds the first surface of the laminate so as not to come into contact with the first shaping surface, thereby appropriately preventing the second region of the laminate from being deformed by the weight.
