Mode for Carrying Out the Invention

[0012] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0013] <Parts and Skin Member> First, with reference to FIGS. 1 to 4, parts 2 manufactured by the manufacturing apparatus 1 according to an embodiment of the present disclosure and the skin member 4 used for manufacturing the parts 2 will be described.

[0014] The part 2 of the present embodiment is, for example, an interior member disposed in the interior of a vehicle and constituting a part of the interior. However, the part 2 is not limited thereto and may be disposed in an aircraft, a ship, a building, or other internal spaces.

[0015] FIG. 1 is a cross-sectional view showing a cross-section of the part 2. As shown in FIG. 1, the part 2 has a base material 20 and a skin material 21 attached to the base material 20.

[0016] The base material 20 is a resin part formed of a thermoplastic resin. The thermoplastic resin is, for example, an ABS resin, polypropylene (PP), polyethylene (PE), acrylic resin, polycarbonate (PC) resin, polyamide, polyethylene terephthalate (PET), or modified polyphenylene ether (modified-PPE).

[0017] The base material 20 has a first surface 20a and a second surface 20b on the side opposite to the first surface 20a.

[0018] The skin material 21 is formed of a film material or a fiber material and constitutes the design surface of the component 2. The film material is formed of a resin. The resin is, for example, polyvinyl chloride (PVC) or polyurethane resin (PU). The fiber material includes knitted fabrics, woven fabrics, non-woven fabrics, and other fabrics.

[0019] The skin material 21 has a first surface 21a that becomes the design surface of the component 2 and a second surface 21b on the side opposite to the first surface 21a. The second surface 21b of the skin material 21 is attached to the first surface 20a of the base material 20. The attachment is performed, for example, by an adhesive, a pressure-sensitive adhesive, or frame lamination.

[0020] The skin material 21 has a central portion 21c attached to the first surface 20a of the base material 20 and a peripheral portion 21d provided around the central portion 21c and attached to the second surface 20b of the base material 20.

[0021] FIG. 2 is a top view showing the skin member 4 prepared for attachment to the base material 20. FIG. 3 is a cross-sectional view showing the A-A cross-section of FIG. 2. As shown in FIG. 3, the skin member 4 includes a first layer 41 and a second layer 42 laminated on the first layer 41. The first layer 41 is the skin material 21. The second layer 42 is a sheet adhered to the first layer 41 for the purpose of protecting the first layer 41 from dust, supporting the flexible first layer 41, and other purposes. The second layer 42 is peeled off before the first layer 41 is attached to the base material 20. The second layer 42 is formed of, for example, paper or resin. The resin is, for example, polyethylene terephthalate (PET).

[0022] The stretchability of the first layer 41 is higher than that of the second layer 42. The stretchability can be evaluated by the force (unit: Newton) required to stretch a 25.4 mm wide sheet by 10%. The greater the force required to stretch by 10%, the lower the stretchability is evaluated. Depending on the material, thickness, form (film material or fiber material), and other factors of the sheet, there are also sheets that cannot be stretched by 10% or more. For example, the elongation rate of general paper is 1% or more and 3% or less. The stretchability of such a sheet is evaluated as extremely low. The first layer 41 requires, for example, a force of 3 N or more and 25 N or less to stretch a 25.4 mm wide sheet by 10%. The second layer 42 is, for example, a sheet that cannot be stretched by 10% or more.

[0023] The first layer 41 has a first surface 41a that becomes the first surface 21a of the skin material 21 (both refer to FIG. 1) and a second surface 41b that becomes the second surface 21b of the skin material 21 (both refer to FIG. 1).

[0024] As shown in FIG. 2, the skin member 4 includes a central portion 43 corresponding to the central portion 21c of the skin material 21 and a peripheral portion 44 corresponding to the peripheral portion 21d of the skin material 21.

[0025] The skin member 4 further includes one or more locking portions 45 extending from the peripheral portion 44. In the present embodiment, the skin member 4 includes a first locking portion 45a, a second locking portion 45b, a third locking portion 45c, a fourth locking portion 45d, a fifth locking portion 45e, and a sixth locking portion 45f. The number and arrangement of the locking portions 45 can be appropriately changed according to the size and shape of the skin member 4.

[0026] In the present embodiment, the first locking portion 45a, the third locking portion 45c, the fourth locking portion 45d, and the sixth locking portion 45f are generally triangular in a top view. The second locking portion 45b and the fifth locking portion 45e are generally rectangular in a top view.

[0027] The skin member 4 further includes one or more holes 46 penetrating from the first layer 41 to the second layer 42. The holes 46 are arranged in the locking portions 45. In the present embodiment, the skin member 4 includes a first hole 46a arranged in the first locking portion 45a, a second hole 46b arranged in the second locking portion 45b, a third hole 46c arranged in the third locking portion 45c, a fourth hole 46d arranged in the fourth locking portion 45d, a fifth hole 46e arranged in the fifth locking portion 45e, and a sixth hole 46f arranged in the sixth locking portion 45f.

[0028] The inner diameter φ1 of the hole 46 is, for example, 2 mm or more and 5 mm or less.

[0029] The skin member 4 further includes one or more perforations 47 provided between one or more locking portions 45 and the peripheral edge portion 44. The perforations 47 include alternately repeated cut portions and non-cut portions. The cut portions are cuts penetrating from the first layer 41 to the second layer 42. In the present embodiment, the skin member 4 includes a first perforation 47a provided between the first locking portion 45a and the peripheral edge portion 44, a second perforation 47b provided between the second locking portion 45b and the peripheral edge portion 44, a third perforation 47c provided between the third locking portion 45c and the peripheral edge portion 44, a fourth perforation 47d provided between the fourth locking portion 45d and the peripheral edge portion 44, a fifth perforation 47e provided between the fifth locking portion 45e and the peripheral edge portion 44, and a sixth perforation 47f provided between the sixth locking portion 45f and the peripheral edge portion 44. The locking portion 45 is separated from the peripheral edge portion 44 along the perforation 47 under the tensile force in the direction of being pulled away from the peripheral edge portion 44.

[0030] The second layer 42 further includes one or more slits 48 provided in one or more locking portions 45. The slits 48 extend from the hole portion 46 toward the end of the skin member 4. The slits 48 may or may not reach the end of the skin member 4. Further, the slits 48 may extend in a direction away from the central portion 43 of the skin member 4.

[0031] In the present embodiment, the skin member 4 includes a first slit 48a provided in the first locking portion 45a, a second slit 48b provided in the third locking portion 45c, a third slit 48c provided in the fourth locking portion 45d, and a fourth slit 48d provided in the sixth locking portion 45f.

[0032] As shown in FIG. 4, in a top view, the first slit 48a is disposed on the side opposite to the first perforation 47a with the first hole portion 46a interposed therebetween. The first slit 48a extends from the first hole portion 46a to the end of the first locking portion 45a. The first slit 48a extends in a direction intersecting the first perforation 47a. The same applies to the second slit 48b to the fourth slit 48d.

[0033] <Manufacturing apparatus> Next, the manufacturing apparatus 1 for the component 2 will be described with reference to FIGS. 5 and 6. The manufacturing apparatus 1 separates the second layer 42 from the first layer 41 of the skin member 4 to obtain the skin material 21, and further attaches the skin material 21 to the base material 20 to manufacture the component 2.

[0034] As shown in FIG. 5, the manufacturing apparatus 1 includes six pins (an example of a holding portion) 50 that are respectively inserted into six holes 46 (the first hole 46a to the sixth hole 46f) of the skin member 4 (only two pins 50 appear in FIG. 5). The six pins 50 hold the skin member 4 by being respectively inserted into the six holes 46 of the skin member 4.

[0035] The pin 50 has a cylindrical shape extending along the vertical direction (the arrow Z direction in FIG. 5).

[0036] As shown in FIG. 6, the pin 50 has an outer diameter φ2 and a height h. The outer diameter φ2 of the pin 50 is larger than the inner diameter φ1 of the hole 46 of the skin member 4. The outer diameter φ2 is, for example, 3 mm or more and 6 mm or less. Also, the height h of the pin 50 is larger than the thickness of the skin member 4.

[0037] As shown in FIG. 5, the manufacturing apparatus 1 may include six moving portions 51 that serve as bases for the six pins 50 (only two moving portions 51 appear in FIG. 5). The six moving portions 51 are movable along the horizontal direction (refer to the arrow X direction in FIG. 5) so as to move away from each other from the initial position P0. By moving the six moving portions 51 so as to move away from each other, the six pins 50 move away from each other. The six pins 50 apply tension to the skin member 4 (skin material 21) by moving away from each other.

[0038] The manufacturing apparatus 1 may include an adjustment unit 52 that suppresses the tension applied to the skin material 21 to a certain level or less. The adjustment unit 52 avoids damage to the skin material 21 (for example, an unintentional break at the perforation 47) due to excessive tension applied to the skin material 21. The adjustment unit 52 may be, for example, an air cylinder, an electric actuator, a hydraulic cylinder, or a spring that is integrally provided on the moving part 51. The air cylinder drives the moving part 51 by receiving air from a compressor in the factory and stops at a position where the driving force by the air balances the tension applied to the skin material 21. That is, the tension applied to the skin material 21 is suppressed to a certain level or less. The electric actuator, the hydraulic cylinder, and the spring may, like the air cylinder, suppress the tension applied to the skin material 21 to a certain level or less by the balance of the tension, or may suppress the tension applied to the skin material 21 to a certain level or less by restricting the moving distance of the moving part 51.

[0039] The manufacturing apparatus 1 may include a pressing part 53 that is provided on the moving part 51 and is movable between an initial position P1 indicated by a broken line and a pressing position P2 indicated by a solid line. When the pressing part 53 is located at the pressing position P2, it presses the periphery of the hole part 46 in the skin member 4. When the pressing part 53 is located at the initial position P1, it releases the pressing.

[0040] The pressing part 53 has a rotating shaft 53a driven by an actuator (not shown), a pressing member 53b, and a connecting part 53c that connects the rotating shaft 53a and the pressing member 53b.

[0041] The manufacturing apparatus 1 further includes an upper mold 54 that supports the base material 20 and a base 55 that is arranged to face the upper mold 54 and receives the base material 20 supported by the upper mold 54. The upper mold 54 moves the base material 20 between an initial position P3 and a pressing position P4 along the vertical direction (the arrow Z direction in FIG. 5). When the upper mold 54 is located at the pressing position P4, it presses the base material 20 and the skin material 21 toward the base 55. When the upper mold 54 is located at the initial position P3, it releases the pressing.

[0042] The base 55 has a concave surface 55a corresponding to the shape of the first surface 20a (see FIG. 1) of the base material 20.

[0043] The manufacturing apparatus 1 further includes six plate members 56 that are movable between a retracted position P5 indicated by a dashed line and an advanced position P6 indicated by a solid line along the horizontal direction (the direction of arrow X in FIG. 5). (In FIG. 5, two plate members 56 are shown.) The retracted position P5 is a position that does not overlap with the base material 20 supported by the upper mold 54 located at the pressing position P4 in a top view. Also, the advanced position P6 is a position that overlaps with the base material 20 supported by the upper mold 54 located at the pressing position P4 in a top view. The plate members 56 are driven by an actuator.

[0044] <Manufacturing method> Next, with reference to FIGS. 7 to 14, the manufacturing method of the component 2 will be described.

[0045] The manufacturing method of the component 2 includes a step S1 of preparing the skin member 4, a step S2 of inserting the pin 50 of the manufacturing apparatus 1 into the hole 46 of the skin member 4, a step S3 of separating the second layer 42 of the skin member 4 from the first layer 41, a step S4 of attaching a part of the skin material 21 to the base material 20, a step S5 of holding the skin material 21, a step S6 of pressing the skin material 21 with the plate member 56, and a step S7 of winding the skin material 21 around the base material 20.

[0046] As shown in FIG. 7, first, in step S1, an operator prepares the skin member 4 and arranges the first layer 41 of the skin member 4 facing the pin 50 of the manufacturing apparatus 1.

[0047] In step S1, the moving part 51 of the manufacturing apparatus 1 is located at the initial position P0. The pressing part 53 is located at the initial position P1. The plate member 56 is located at the advanced position P6. By being located at the advanced position P6, the plate member 56 enables the temporary placement of the skin member 4 on the plate member 56. The upper mold 54 is located at the initial position P3. The upper mold 54 supports the first surface 20a of the base material 20 facing the concave surface 55a of the base 55.

[0048] The central portion 43 of the skin member 4 is disposed between the base material 20 supported by the upper mold 54 and the base 55. The hole portion 46 of the skin member 4 is disposed in the vicinity of the pin 50.

[0049] Next, in step S2, an operator inserts the pin 50 of the manufacturing apparatus 1 into the hole portion 46 of the skin member 4. FIG. 8 is an explanatory view showing a state in which the pin 50 of the manufacturing apparatus 5 is inserted into the hole portion 46 of the skin member 4.

[0050] As shown in FIG. 8(a), in the present embodiment, the operator places the first layer 41 of the skin member 4 on the lower side (the direction opposite to the arrow Z in FIG. 8(a)), and moves the locking portion 45 of the skin member 4 so as to cover the pin 50 from above (the direction of the arrow Z in FIG. 8(a)).

[0051] Furthermore, as shown in FIG. 8(b), the hole portion 46 of the skin member 4 is pushed into the pin 50 from above (the direction of the arrow Z in FIG. 8(b)). Thereby, the pin 50 is inserted into the hole portion 46.

[0052] As described above, the outer diameter φ2 of the pin 50 is larger than the inner diameter φ1 of the hole portion 46 of the skin member 4 (see FIG. 8(a)). Therefore, the pin 50 is inserted while expanding the hole portion 46 of the skin member 4. Both the first layer 41 and the second layer 42 of the skin member 4 are pushed downward (the direction opposite to the arrow Z in FIG. 8(b)) while the periphery of the hole portion 46 is dragged along the outer peripheral surface of the pin 50.

[0053] As described above, the stretchability of the first layer 41 of the skin member 4 is higher than that of the second layer 42. Therefore, when the pin 50 is inserted into the hole portion 46, in the first layer 41, the hole portion 46 easily expands to the outer diameter φ2 of the pin 50. On the other hand, in the second layer 42, the hole portion 46 hardly expands to the outer diameter φ2 of the pin 50. Therefore, the second layer 42 cannot follow the downward movement of the first layer 41 and is mainly separated from the first layer 41 around the hole portion 46.

[0054] Pin 50 is inserted into the hole 46 in a state where a part of the second layer 42 of the skin member 4 is separated from and lifted above the first layer 41. As shown in FIG. 8(c), when the skin member 4 is pushed down to the lower end of the pin 50, the second layer 42 separates from the first layer 41 over a wider range. The second layer 42 catches on the outer peripheral surface of the pin 50 and rises above the first layer 41.

[0055] Next, as shown in FIG. 9, in step S3, the manufacturing apparatus 1 moves the pin 50 and the moving part 51 from the initial position P0 shown by the broken line along the horizontal direction (the direction of arrow X in FIG. 9).

[0056] Thereby, the skin member 4 is stretched without slackening in the horizontal direction (the direction of arrow X in FIG. 9). Further, the periphery of the hole 46 of the skin member 4 is dragged along the outer peripheral surface of the pin 50 and pulled away from the central part 43. At this time, the first layer 41 is stretched as the pin 50 moves. On the other hand, the second layer 42, which has lower stretchability than the first layer 41, cannot follow the deformation of the first layer 41 and separates further from the first layer 41.

[0057] The moving part 51 may move the pin 50 along the direction in which the slit 48 (see FIG. 2) of the second layer 42 extends. Thereby, the locking part 45 of the second layer 42 separates from and rises above the first layer 41 individually at the location sandwiching the slit 48.

[0058] Furthermore, in step S3, the operator peels the second layer 42 from the first layer 41. The periphery of the hole 46 and the slit 48 (see FIG. 2) of the second layer 42 are separated from and lifted above the first layer 41. The operator starts from such a lifted part above the first layer 41 and peels the entire second layer 42 from the first layer 41 to completely separate them. After the peeling of the second layer 42, the first layer 41 is held facing the first surface 20a of the base material 20.

[0059] Next, in step S4, as shown in FIG. 10, the manufacturing apparatus 1 moves the plate member 56 from the advanced position P6 to the retracted position P5.

[0060] Furthermore, the manufacturing apparatus 1 may move the pressing portion 53 from the initial position P1 to the pressing position P2 and press the periphery of the hole portion 46 of the skin member 4.

[0061] FIG. 11(a) is a schematic view showing the positional relationship among the pressing portion 53, the pin 50, the moving portion 51, and the first layer 41 of the skin member 4. As shown in FIG. 11(a), the pressing portion 53 moves from the initial position P1 to the pressing position P2.

[0062] When the pressing portion 53 is located at the pressing position P2, the pressing member 53b presses the first layer 41 of the skin member 4 from above (in the direction of arrow Z in FIG. 11(a)). FIG. 11(b) is a top view showing the positional relationship between the pressing member 53b and the skin member 4. As shown by the dotted drawing in FIGS. 11(a) and (b), the pressing member 53b presses the periphery of the hole portion 46 of the skin member 4. The pressing member 53b may press the portion between the perforation 47 and the hole portion 46 of the skin member 4 along the perforation 47.

[0063] Thereby, the pressing portion 53 can suppress the deformation of the first layer 41 in the portion between the hole portion 46 and the perforation 47 of the skin member 4. For this reason, the manufacturing apparatus 1 can prevent breakage, wrinkles, and creases from occurring at unintended locations of the first layer 41 of the skin member 4.

[0064] Furthermore, in step S4, the manufacturing apparatus 1 attaches the base material 20 to a part of the first layer 41 of the skin member 4. As shown in FIG. 12(a), the upper mold 54 supporting the base material 20 moves downward (in the direction opposite to the arrow Z in FIG. 12(a)) from the initial position P3 shown by the broken line. Along with the movement of the upper mold 54, the base material 20 is pressed against the first layer 41 of the skin member 4. Thereby, the central portion 43 of the first layer 41 of the skin member 4 is attached as the skin material 21 to the first surface 20a of the base material 20.

[0065] The first layer 41 of the skin member 4 is pushed downward (in the direction opposite to the arrow Z in FIG. 12(a)) as the upper mold 54 and the base material 20 move. As a result, the pin 50 inserted into the hole 46 and the moving part 51 integrated with the pin 50 are pulled horizontally toward the upper mold 54 through the skin member 4. On the other hand, the adjusting part 52 adjusts the position of the moving part 51 along the horizontal direction (the arrow X direction in FIG. 12(a)) to suppress the tension applied to the skin member 4 below a certain level. Thereby, the manufacturing apparatus 1 can prevent the skin member 4 from being excessively pulled and broken by the movement of the upper mold 54 and the base material 20.

[0066] As shown in FIG. 12(b), the upper mold 54 moves the first layer 41 of the skin member 4 and the base material 20 to the pressing position P4. At the pressing position P4, the upper mold 54 presses the first layer 41 of the skin member 4 and the base material 20, and adheres the central part 43 of the first layer 41 of the skin member 4 to the base material 20.

[0067] Next, in step S5, the manufacturing apparatus 1 holds the first layer 41 so that the perforation 47 provided in the first layer 41 of the skin member 4 is disposed at a position separated from the end of the base material 20 in a state where a part of the first layer 41 of the skin member 4 is attached to the base material 20.

[0068] The perforation 47 may be disposed at a position facing the plate member 56 in the horizontal direction (the arrow X direction in FIG. 12(b)).

[0069] In step S6, as shown in FIG. 12(c), the plate member 56 moves from the retracted position P5 to the advanced position P6.

[0070] FIG. 13 is an enlarged view showing the state of movement of the plate member 56 with the C part of FIG. 12(c) enlarged. As shown in FIG. 13(a), the plate member 56 moves along the horizontal direction (the arrow X direction in FIG. 13(a)) toward the space between the end of the base material 20 and the perforation 47 of the skin member 4.

[0071] Furthermore, as shown in Fig. 13(b), the plate member 56 presses the first layer 41 of the skin member 4 toward the upper mold 54 and the base material 20 along the horizontal direction (the direction of arrow X in Fig. 13(b)).

[0072] The first layer 41 of the skin member 4 is stretched by the tip of the plate member 56 near the perforation 47. As a result, the first layer 41 receives a shearing force across the perforation 47. As the plate member 56 moves, the first layer 41 is further stretched to the limit.

[0073] As shown in Fig. 13(c), when the plate member 56 further moves toward the advancing position P6, the first layer 41 of the skin member 4 is cut by the perforation 47. As a result, the locking portion 45 is separated from the peripheral edge portion 44.

[0074] Next, in step S7, the plate member 56 moves to the advancing position P6 (see Fig. 12(c)) while dragging the peripheral edge portion 44 of the skin member 4 cut from the locking portion 45. The peripheral edge portion 44 is folded at the end of the base material 20 as the plate member 56 moves and is wound onto the second surface 20b side. As a result, the skin material 21 is wound around the base material 20. The skin material 21 wound onto the second surface 20b side is pressed against the second surface 20b, and as shown in Fig. 14, the manufacturing apparatus 1 manufactures the component 2 with the skin material 21 attached to the base material 20.

[0075] The manufacturing apparatus 1 of the present disclosure is a manufacturing apparatus for the component 2 with the skin material 21 attached to the base material 20. The manufacturing apparatus 1 includes a pin 50 that holds the skin material 21 such that the perforation 47 provided in the skin material 21 is disposed at a position separated from the end of the base material 20 in a state where a part of the skin material 21 is attached to the base material 20, and a plate member 56 that moves toward the space between the end of the base material 20 and the perforation 47 to press the skin material 21.

[0076] Thereby, the plate member 56 can stretch the skin member 4 between the end of the base material 20 and the perforation 47 and disconnect it near the perforation 47. Therefore, the manufacturing apparatus 1 can prevent the skin member 4 from being disconnected at unintended locations other than the perforation 47.

[0077] The plate member 56 moves toward the base material 20, cuts off the perforation 47 of the skin material 21, and wraps the skin material 21 on the base material 20 side from the perforation 47 around the base material 20.

[0078] Thereby, the manufacturing apparatus 1 can manufacture the component 2 by winding the skin material 21 around the base material 20. Further, the cutting of the perforation 47 and the winding of the base material 20 can be performed simultaneously, and the manufacturing cycle time of the component 2 can be shortened.

[0079] The pin 50 is inserted into the hole portion 46 provided in the skin material 21, and pulls the skin material 21 in a direction away from the end portion of the base material 20.

[0080] Thereby, the pin 50 can stretch the skin material 21 between the end portion of the base material 20 and the hole portion 46. For this reason, the manufacturing apparatus 1 can hold the skin member 4 in a stretched state between the base material 20 and the pin 50. Thereby, the manufacturing apparatus 1 can prevent wrinkles and distortion of the skin member 4 from occurring, and can attach the skin material 21 to the base material 20 beautifully.

[0081] The manufacturing apparatus 1 includes an adjustment unit 52 that suppresses the tension applied to the skin material 21 during holding by the pin 50 to a certain level or less.

[0082] Thereby, the manufacturing apparatus 1 can suppress breakage and deformation at unintended locations of the skin material 21.

[0083] The manufacturing method of the present disclosure is a manufacturing method of the component 2 with the skin material 21 attached to the base material 20, and includes a step S4 of attaching a part of the skin material 21 to the base material 20, and a step S5 of holding the skin material 21 so that the perforation 47 provided in the skin material 21 is disposed at a position separated from the end portion of the base material 20, and a step S6 of moving the plate member 56 toward between the end portion of the base material 20 and the perforation 47 to press the skin material 21.

[0084] As a result, the manufacturing apparatus 1 can hold the skin member 4 in a state of being stretched between the base material 20 and the pin 50. For this reason, the manufacturing apparatus 1 can suppress the generation of wrinkles and creases in the skin member 4 and prevent disconnection at unintended locations other than the perforations 47.

[0085] The manufacturing apparatus 1 for the component 2 of the present disclosure is a manufacturing apparatus that separates the second layer 42 of the skin member 4, which is laminated on the first layer 41 and has lower stretchability than the first layer 41, from the first layer 41, and has a pin 50 that is inserted into the hole portion 46 and has an outer diameter φ2 larger than the inner diameter φ1 of the hole portion 46.

[0086] When the pin 50 is inserted into the hole portion 46, in the first layer 41, the hole portion 46 easily expands to the outer diameter φ2 of the pin 50. On the other hand, in the second layer 42, which has lower stretchability than the first layer 41, the hole portion 46 hardly expands to the outer diameter φ2 of the pin 50. For this reason, the second layer 42 cannot follow the downward movement of the first layer 41 and separates from the first layer 41 mainly centered on the hole portion 46. As a result, the manufacturing apparatus 1 can easily separate the second layer 42 of the skin member 4 from the first layer 41.

[0087] The second layer 42 includes a slit 48 that extends from the hole portion 46 toward the end of the skin member 4, and the manufacturing apparatus 1 includes a moving portion 51 that can move the pin 50 along the direction in which the slit 48 extends with the pin 50 inserted into the hole portion 46 of the skin member 4.

[0088] As a result, the locking portion 45 of the second layer 42 separates and floats individually from the first layer 41 at the location sandwiching the slit 48. As a result, the operator can easily separate the second layer 42 of the skin member 4 from the first layer 41 starting from this slit 48.

[0089] The slit 48 extends in a direction away from the central portion 43 of the skin member 4, and the manufacturing apparatus 1 stretches the skin member 4 along the direction in which the slit 48 extends with the pin 50 inserted into the hole portion 46 of the skin member 4.

[0090] As a result, the manufacturing apparatus 1 can separate the second layer 42 of the skin member 4 from the first layer 41 while stretching the skin member 4 between the base material 20 and the pin 50. Therefore, the manufacturing tact of the component 2 can be shortened.

[0091] Moreover, the manufacturing method of the component 2 includes a step S1 of preparing a skin member 4 having a first layer 41, a second layer 42 laminated on the first layer 41 and having lower stretchability than the first layer 41, and a hole portion 46 penetrating from the first layer 41 to the second layer 42, and a step S2 of inserting a pin 50 having an outer diameter φ2 larger than the inner diameter φ1 of the hole portion 46 into the hole portion 46 of the skin member 4.

[0092] As a result, when the pin 50 is inserted into the hole portion 46, in the first layer 41, the hole portion 46 is likely to expand to the outer diameter φ2 of the pin 50. On the other hand, in the second layer 42 having lower stretchability than the first layer 41, the hole portion 46 is less likely to expand to the outer diameter φ2 of the pin 50. Therefore, the second layer 42 cannot follow the downward movement of the first layer 41 and mainly separates from the first layer 41 centering around the hole portion 46. As a result, the manufacturing method can easily separate the second layer 42 of the skin member 4 from the first layer 41.

[0093] The skin member 4 includes a first layer 41, a second layer 42 laminated on the first layer 41 and having lower stretchability than the first layer 41, a hole portion 46 penetrating from the first layer 41 to the second layer 42, and a slit 48 provided in the second layer 42 and extending from the hole portion 46.

[0094] As a result, when the first layer 41 is stretched, the second layer 42 having lower stretchability than the first layer 41 cannot follow the deformation of the first layer 41 and separates from the first layer 41. The second layer 42 floats up from near the hole portion 46 and the slit 48. Therefore, the skin member 4 can peel off and separate the second layer 42 from the first layer 41 starting from the vicinity of the hole portion 46 and the slit 48.

[0095] As described above, according to the manufacturing apparatus, manufacturing method, and skin member of the present disclosure, it is possible to provide a manufacturing apparatus, a manufacturing method, and a skin member in which a protective layer covering the skin material can be easily separated from the skin material to be attached to the base material.

However, the present disclosure is not limited to the above embodiments, and various modifications can be made without departing from the gist of the invention. In particular, a plurality of modifications described in this specification can be arbitrarily combined as needed.
