Description

Technical Field

[0001] This invention relates to an epidermal material processing apparatus and a method for manufacturing an interior member for a vehicle.

Background Art

[0002] In the passenger compartment of a vehicle such as an automobile, various interior members for vehicles such as an instrument panel, a floor console, a door trim, and a pillar garnish are arranged. Since interior members for vehicles greatly contribute to the texture and atmosphere in the passenger compartment, there is a type in which an epidermal material is attached to the outside of a synthetic resin base material formed into a required shape to improve the texture. When attaching the epidermal material to the base material, an epidermal material formed larger than the entire area of the surface of the base material is adhered to the surface of the base material, and the terminal of the epidermal material left so as to extend from the edge of the base material is wound around the back side of the base material and fixed to the back surface of the base material using an adhesive or a tacker or the like. It has been proposed to mechanically perform such terminal processing by a processing apparatus (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] When a surface material is folded over at the opening edge of an opening formed in the base material and joined to the back surface of the base material, it is necessary to pre-form notches, for example, to match the corner of the opening, in order to suppress tension in the folded surface material.

[0022] Next, preferred embodiments of the surface material processing apparatus and the method for manufacturing interior components for vehicles according to the present invention will be described below with reference to the attached drawings. The embodiments and drawings described below are illustrative of some embodiments of the present invention and are not intended to limit the scope to these configurations. They can be modified as appropriate without departing from the spirit of the present invention.

[0023] The surface material processing apparatus 20 according to the embodiment shown in Figures 1 to 4 obtains a vehicle interior member 10 (see Figure 16) by folding back a surface material 16 placed on the surface of a base material 12 at the opening edge of an opening 14 provided in the base material 12 and attaching it to the back surface of the base material 12. The surface material processing apparatus 20 first forms a cut N (see Figure 16) in the extended portion 17 of the surface material 16 that extends inward from the opening 14, and then folds the extended portion 17 back to the back surface at the opening edge of the opening 14. The surface side of the vehicle interior member 10 is the side that faces the passenger compartment or cargo area and is visible to the passenger when the vehicle interior member 10 is installed, while the back side of the vehicle interior member 10 is the side that faces the vehicle body and is not visible to the passenger when the vehicle interior member 10 is installed.

[0024] As shown in Figure 16, the interior member 10 for the vehicle is a curved plate-like body with a convex surface, and has an opening 14 in the center that penetrates in the front-to-back direction. In this embodiment, the opening 14 is substantially rectangular in plan view (see Figure 5). Components such as a meter, switch, register, airbag door, and seat belt anchor position adjustment slider are placed in the opening 14. As shown in Figure 5, in the following description, the short side of the opening 14 is referred to as the first direction, and the long side of the opening 14 is referred to as the second direction. The direction in which the cut N extends when forming the cut N is referred to as the third direction. In this embodiment, the third direction is the direction that passes through the corner portion of the opening 14 and extends intersecting the first and second directions (the direction in which the bisector of the corner portion extends). The direction in which the cut N extends (the third direction) is set for each corner portion of the opening 14. Furthermore, the side of the opening 14 that moves from the center towards the edge of the opening is called the outside, and the side of the opening 14 that moves away from the edge of the opening 14 towards the center of the opening is called the inside.

[0025] The base material 12 is a rigid, plate-like member that forms the shape of the interior component 10 for the vehicle. As the base material 12, for example, a resin molded product formed into the required shape from a synthetic resin such as polypropylene (PP) by injection molding is used. The base material 12 has an opening 14 that penetrates in the front-back direction. On the back surface of the base material 12, the corner portion of the opening edge of the opening 14 is an inclined surface that slopes towards the front side as it extends outward in a third direction from the opening edge (see Figures 6 to 9). In addition, on the base material 12, the opening edge of the opening 14 extending in the first direction is curved towards the back side (see Figure 14).

[0026] The surface material 16 is a component that forms the surface of the interior component 10 for a vehicle. The surface material 16 is flexible. The surface material 16 is made of, for example, polyurethane, olefin-based (TPO), vinyl chloride-based or styrene-based elastomer, or polyurethane or vinyl chloride-based synthetic leather. The surface material 16 is not limited to a single-layer structure of the aforementioned material, but may also have a multi-layer structure with a foam or the like on the back side. As the back layer, for example, polyurethane foam, foam made of olefin-based materials such as polyethylene or polypropylene, styrene foam, or nonwoven fabric or woven fabric can be used. The surface material 16 is formed with an outer shape that is slightly larger than the base material 12, and a surface material opening 16a that is slightly smaller than the opening 14 is formed. Therefore, when the surface material 16 is placed on the base material 12, the extended portion 17 of the surface material 16 extends inside the opening 14 of the base material 12 (see Figure 15).

[0027] In the vehicle interior component 10, the surface material 16 is attached to the base material 12. The surface material 16 and the base material 12 are attached by one or more means, such as by an adhesive layer or tack layer pre-formed on the surface material 16 and / or the base material 12, by an adhesive applied to the surface material 16 and / or the base material 12, or by welding using high frequency, ultrasound, or heat. In this embodiment, the surface material 16 has a tack layer on its back surface, and is attached to the base material 12 by this tack layer.

[0028] As shown in Figure 1, the surface material processing apparatus 20 according to the embodiment includes a member installation section 22 for installing the base material 12 and the surface material 16, a member holding section 26 for holding the base material 12 and the surface material 16 installed in the member installation section 22, a cut forming section 30 for forming a cut N in the extended portion 17 of the surface material 16, and winding sections 50, 60, 70 for folding the extended portion 17 of the surface material 16 back at the opening edge of the opening 14 of the base material 12 and wrapping it around the back surface of the base material 12. The winding sections 50, 60, 70 include a corner winding section 50 for winding the extended portion 17 of the surface material 16 around the corner portion of the opening edge of the opening 14, a first winding section 60 for winding the extended portion 17 of the surface material 16 around the opening edge of the opening 14 in a first direction, and a second winding section 70 for winding the extended portion 17 of the surface material 16 around the opening edge of the opening 14 in a second direction.

[0029] As shown in Figures 3 and 4, the component mounting section 22 is supported on the upper side of the device base 21. The component mounting section 22 has a mounting surface 22a formed to match the shape of the surface of the interior component 10 for the vehicle, and a mounting opening 24 formed vertically through the mounting surface 22a (see Figure 2). The base material 12 is mounted on the mounting surface 22a, overlapping the surface material 16, and the opening 14 of the base material 12 is positioned to match the mounting opening 24. On the mounting surface 22a, the surface material 16 and the base material 12 are mounted with the surface side facing downwards and the back side facing upwards, and the extension portion 17 of the surface material 16 is positioned inside the mounting opening 24 (see Figure 6).

[0030] As shown in Figure 1, the member holding portion 26 is provided on the member installation portion 22. The member holding portion 26 can be changed between a first position (see Figures 3 and 4) in which it is retracted from the installation surface 22a of the member installation portion 22, and a second position (see Figures 1 and 2) in which it presses the back surface of the base material 12 installed on the installation surface 22a toward the installation surface 22a. When forming the cut N and wrapping the extension portion 17 from the front side of the base material 12, the member holding portion 26, in the second position, presses the base material 12 from the back side to suppress the base material 12 from lifting up.

[0031] As shown in Figures 6-8, the notch forming section 30 includes a cutting blade 32 that forms a notch N in the extended portion 17 of the surface material 16 that extends inward into the opening 14, and a cutting blade moving section 40 that moves the cutting blade 32 to form the notch N from a position close to the opening edge of the extended portion 17 toward the end of the extended portion 17 (from the outside in the third direction toward the inside). The cutting blades 32 are provided corresponding to each corner portion of the opening 14. In this embodiment, there are two cutting blades 32 that form an extended portion 17 of a predetermined width that folds back into the corner portion of the opening 14, and these two cutting blades 32 are arranged for each corner portion. The two cutting blades 32 are arranged parallel to each other with a gap between them in a direction perpendicular to the third direction (see Figure 5).

[0032] As shown in Figure 9, the cutting blade 32 is attached to a cutting blade holder 34 which is moved by the cutting blade moving unit 40. The cutting blade 32 is an inclined blade that is inclined in one direction in the width direction. The inclined blade of the cutting blade 32 according to this embodiment is not a mountain shape that is inclined in both directions in the width direction from the tip, but is inclined only in one direction in the width direction. The cutting blade 32 is arranged so that the inclined blade facing upward extends in the third direction, and the width direction is aligned with the third direction (the direction in which the cut N extends). In addition, the inclined blade of the cutting blade 32 is inclined downward as it moves away from the side close to the opening edge of the opening 14 (as it moves from the outside in the third direction to the inside), and the tip is positioned on the side close to the opening edge of the opening 14. The cutting blade moving unit 40 moves the above cutting blade 32 upward from the front side to the back side of the base material 12 to form the cut N. The cutting blade moving unit 40 according to this embodiment moves the cutting blade 32 back and forth in the vertical direction as well as in the third direction.

[0033] As shown in Figure 5, two cutting blade holders 34 are arranged spaced apart in a direction perpendicular to the third direction. One cutting blade 32 is attached to each cutting blade holder 34 so as to protrude from the upper edge of the cutting blade holder 34 (see Figure 9). Each cutting blade holder 34 is attached to a cutting blade arm 46 of the cutting blade moving section 40, which will be described later.

[0034] As shown in Figure 9, the notch forming section 30 includes a position adjustment section 36 that adjusts the position of the cutting edge of the cutting blade 32 between a direction approaching the opening edge of the base material 12 (outward in the third direction) and a direction away from the opening edge (inward in the third direction). A position adjustment section 36 is provided for each cutting blade 32. The position adjustment section 36 according to this embodiment is formed in the cutting blade holder 34 and has a cutting blade adjustment hole 36a which is an elongated hole shape with its long side extending in the third direction, and a cutting blade adjustment bolt 36b which is screwed into the cutting blade arm 46 through the cutting blade adjustment hole 36a. The position adjustment section 36 allows the cutting edge of the cutting blade 32 to be moved in the third direction by loosening the cutting blade adjustment bolt 36b and moving the cutting blade holder 34 along the cutting blade adjustment hole 36a, and the cutting blade holder 34 can be fixed by tightening the cutting blade adjustment bolt 36b.

[0035] As shown in Figure 9, the notch forming section 30 is equipped with a support section 38 that rises together with the cutting blade 32, which is moved by the cutting blade moving section 40, and moves the extension section 17 that folds back to the corner portion of the opening 14 to the back side of the base material 12. The support section 38 is attached between the two cutting blade arms 46 of the cutting blade moving section 40, which will be described later, and is positioned between the two cutting blades 32 (see Figure 5). The upper end of the support section 38 is positioned lower than the tip of the cutting blade 32. In addition, the outer edge of the support section 38 in the third direction is positioned at the same position as the tip of the cutting blade 32 or further out in the third direction than the tip. When the support section 38 rises together with the cutting blade 32, it contacts the extension section 17 at the timing after the tip of the cutting blade 32 has come into contact with the extension section 17 of the surface material 16, pushing the extension section 17 upward toward the back side of the base material 12. The position of the support section 38 is adjustable in the third direction.

[0036] As shown in Figures 6 to 8, the cutting blade moving unit 40 according to this embodiment includes a first cutting blade operating unit 42 installed on the device base 21, a cutting blade base 43 that moves up and down by the first cutting blade operating unit 42, a second cutting blade operating unit 44 installed on the cutting blade base 43, and a cutting blade arm 46 that moves up and down in a third direction by the second cutting blade operating unit 44 and to which a cutting blade holder 34 is attached. The first cutting blade operating unit 42 and the second cutting blade operating unit 44 use pneumatic cylinders. The cutting blade base 43 is equipped with four second cutting blade operating units 44, corresponding to four sets of cutting blades 32 that form notches N at the four corner portions of the extension 17. The cutting blade moving unit 40 moves the four sets of cutting blades 32 up and down by operating the first cutting blade operating unit 42, and moves each set of cutting blades 32 in a third direction by operating each of the second cutting blade operating units 44. Specifically, the cutting blade 32 moves between a front position (see Figures 6 and 7(a)) where the tip is positioned below (on the front side of) the opening 14, and a back position (see Figure 7(b)) where the tip passes through the opening 14 and is positioned above (on the back side of) the opening 14, due to the operation of the first cutting blade operating unit 42. When the cutting blade 32 is in the front position, it moves between a retracted position (see Figure 6) where the tip is positioned outside the opening edge of the opening 14, and a processing position (see Figure 7(a)) where the tip is positioned inside the opening 14, due to the operation of the second cutting blade operating unit 44. Since the cutting blade 32 is removed from the opening 14 in the retracted position, the cutting blade 32 can be hidden when installing the base material 12 and the surface material 16 in the member installation section 22 and when removing the vehicle interior member 10 from the member installation section 22.

[0037] As shown in Figures 6 to 8, the corner winding section 50 comprises a base operating section 52 installed on a first winding base 51 supported on a device base 21, a second winding base 53 that moves up and down by the base operating section 52, a corner operating section 54 installed on the second winding base 53, a corner arm 56 that moves up and down in a third direction by the corner operating section 54, and a pressing section 58 provided on the corner arm 56. The base operating section 52 and the corner operating section 54 use pneumatic cylinders. The second winding base 53 has four corner operating sections 54, corresponding to the extensions 17 that are wrapped around each of the four corner sections. The corner winding section 50 moves the four pressing sections 58 up and down by operating the base operating section 52, and moves the pressing sections 58 connected via the corner arm 56 in a third direction by operating each of the corner operating sections 54. Specifically, the pressing portion 58 moves between a front position (see Figures 6 and 7) located below the opening 14 (front side) and a back position (see Figure 8) located above the opening 14 (back side) through the opening 14, by the operation of the base operating portion 52. When the pressing portion 58 is in the back position, it moves between an inner position (see Figure 8(a)) located inside the opening 14 and an outer position (see Figure 8(b)) located outside the opening edge of the opening 14, by the operation of the corner operating portion 54.

[0038] As shown in Figure 6, the corner actuation part 54 is installed so as to be inclined downward from the inside to the outside in the third direction. When the piston rod of the corner actuation part 54 retracts outward in the third direction, it moves diagonally downward, causing the pressing part 58 to move diagonally downward along the back surface of the base material 12, which is inclined downward as it moves outward in the third direction from the opening edge of the opening 14. When the piston rod of the corner actuation part 54 extends inward in the third direction, it moves diagonally upward, causing the pressing part 58 to move diagonally upward along the back surface of the base material 12.

[0039] As shown in Figures 3 and 4, the corner arm 56 is movably positioned between two cutting blades 32 arranged parallel to the corner portion, between two cutting blade holders 34 supporting these cutting blades 32, and between two cutting blade arms 46 supporting these cutting blade holders 34. The pressing portion 58 is also movably positioned between the two cutting blades 32 (see Figure 1). The pressing surface, which is the lower surface of the pressing portion 58, is formed to match the corner portion at the opening edge of the opening 14. The pressing surface of the pressing portion 58 is inclined downward from the inside to the outside in the third direction, matching the back surface of the base material 12, which is inclined downward from the inside to the outside in the third direction.

[0040] The corner winding section 50 allows for adjustment of the vertical position of the pressing section 58 by placing an adjustment material such as a shim plate between the second winding base 53 and the corner operating section 54. Furthermore, the corner winding section 50 allows for adjustment of the position of the pressing section 58 in the third direction by placing an adjustment material such as a shim plate between the corner operating section 54 and the corner arm 56.

[0041] As shown in Figures 10 and 11, the first winding section 60 comprises a first winding actuation unit 62 installed on the second winding base 53, a first winding arm 64 that moves back and forth in a first direction by the first winding actuation unit 62, and a first pressing unit 66 provided on the first winding arm 64. The first winding actuation unit 62 uses a pneumatic cylinder. The first winding section 60 shares the base actuation unit 52 with the corner winding section 50 as a mechanism for moving the first pressing unit 66 back and forth in the vertical direction. Two first winding actuation units 62 are installed on the second winding base 53, corresponding to extensions 17 that wrap around each of the two opening edges facing each other in the first direction at the opening 14. The first winding section 60 moves the two first pressing sections 66 in the vertical direction by operating the base operating section 52, and moves the first pressing sections 66 connected via the first winding arm 64 in the first direction by operating each of the first winding operating sections 62. Specifically, the first pressing section 66 moves between a front position (see Figure 10) located below the opening 14 (front side) and a back position (see Figure 11) located above the opening 14 (back side) through the opening 14. When the first pressing section 66 is in the back position, it moves between an inner position (see Figure 11(a)) located inside the opening 14 and an outer position (see Figure 11(b)) located outside the opening edge of the opening 14 by operating the first winding operating section 62.

[0042] As shown in Figure 10, the first winding actuation part 62 is installed so as to be inclined downward from the inside to the outside in the first direction. When the piston rod of the first winding actuation part 62 retracts outward in the first direction, it moves diagonally downward, causing the first pressing part 66 to move diagonally downward. When the piston rod of the first winding actuation part 62 extends inward in the first direction, it moves diagonally upward, causing the first pressing part 66 to move diagonally upward.

[0043] The first winding section 60 allows for adjustment of the vertical position of the first pressing section 66 by placing an adjustment material such as a shim plate between the second winding base 53 and the first winding operating section 62. Furthermore, the first winding section 60 allows for adjustment of the position of the first pressing section 66 in the first direction by placing an adjustment material such as a shim plate between the first winding operating section 62 and the first winding arm 64.

[0044] As shown in Figures 12 and 13, the second winding section 70 includes a second winding actuation unit 72 installed on the second winding base 53, a second winding arm 74 that moves back and forth in the second direction by the second winding actuation unit 72, a pressing actuation unit 76 provided on the second winding arm 74, and a second pressing unit 78 that moves back and forth vertically by the pressing actuation unit 76. The second winding actuation unit 72 and the pressing actuation unit 76 use pneumatic cylinders. The second winding section 70 shares the base actuation unit 52 with the corner winding section 50 as a mechanism for moving the pressing actuation unit 76 back and forth vertically. Two second winding actuation units 72 are installed on the second winding base 53, corresponding to the extensions 17 that wrap around each of the two opening edges of the opening 14 that face each other in the second direction. The second winding section 70 moves the two second pressing sections 78 back and forth in the vertical direction by operating the base operating section 52, and moves the second pressing section 78, which is connected to the second winding arm 74 and pressing operating section 76, back and forth in the second direction by operating each of the second winding operating sections 72. In addition, the second winding section 70 moves the second pressing section 78 back and forth in the vertical direction by operating the pressing operating section 76.

[0045] Specifically, the second pressing portion 78 moves between a front position (see Figure 12(a)) located below the opening 14 (front side) and a back position (see Figure 12(b)) located above the opening 14 (back side) through the opening 14, by the operation of the base operating portion 52. When the second pressing portion 78 is in the back position, it moves between an inner position (see Figure 12(b)) located inside the opening 14 and an outer position (see Figure 13) located outside the opening edge of the opening 14, by the operation of the second winding operating portion 72. When the second pressing portion 78 is in the outer position, it moves between an isolated position away from the back surface of the base material 12 (see Figure 13(a)) and a pressing position that presses the back surface of the base material 12 (see Figure 13(b)), by the operation of the pressing operating portion 76.

[0046] The second winding section 70 allows for adjustment of the vertical position of the second pressing section 78 by placing an adjustment material such as a shim plate between the second winding base 53 and the second winding operating section 72. Furthermore, the second winding section 70 allows for adjustment of the second position of the second pressing section 78 in the second direction by placing an adjustment material such as a shim plate between the second winding operating section 72 and the second winding arm 74.

[0047] A method for manufacturing the interior components 10 for vehicles using the aforementioned surface material processing device 20 will now be described. The release paper protecting the adhesive layer on the back surface of the surface material 16 is peeled off from the surface material 16, and the surface material 16 is placed on the surface of the base material 12 so that the surface material opening 16a is positioned inside the opening 14. Note that no cuts N are formed in the surface material 16 when the release paper is peeled off. By setting the base material 12 with the surface material 16 on its surface onto the installation surface 22a of the component installation part 22, the opening 14 is positioned to match the installation opening 24. By changing the component holding part 26 from the first position to the second position, the component holding part 26 presses down on the base material 12 and holds the base material 12 and the surface material 16.

[0048] By operating the second cutting blade actuation unit 44, the cutting blade 32 is moved from the retracted position to the processing position, and the cutting blade 32 is positioned facing the surface side of the extended portion 17 of the surface material 16 that extends inside the opening 14 of the base material 12 (see Figures 7(a) and 9(a)). By operating the first cutting blade actuation unit 42, the cutting blade 32 rises from the front position to the back position through the opening 14, forming a cut N in the extended portion 17 (see Figure 7(b)). At this time, the tip of the cutting blade 32 is inserted into a position close to the opening edge of the opening 14 in the extended portion 17, and the cut N is formed from the position close to the opening edge of the opening 14 in the extended portion 17 toward the end of the extended portion 17 (see Figures 9(b) and (c)). Furthermore, during the formation of the cut N by the cutting blades 32, the support portion 38 positioned between the two cutting blades 32 contacts the extension portion 17 from the surface side, and the extension portion 17 between the cut N formed by the two cutting blades 32 is supported from the surface side by the support portion 38 as the formation of the cut N progresses (see Figure 9(d)). By the time the cutting blades 32 rise to the back side position, the cut N has been formed by the cutting blades 32 up to the end of the extension portion 17, and the extension portion 17 between the two cutting blades 32 is bent and set towards the back side of the base material 12 by the support portion 38 which extends in the front-back direction along the opening edge of the opening 14 (see Figure 9(e)). After the cut N has been formed in this way, the cutting blades 32 are returned from the back side position to the front side position, and then returned from the processing position to the retracted position at the front side position.

[0049] By operating the base actuation part 52, the pressing part 58, the first pressing part 66, and the second pressing part 78 are moved from the front side position to the back side position through the opening 14 (see Figures 8(a), 11(a), and 12(b)). By moving the first pressing part 66 along the opening edge of the opening 14 in the first direction from the front side position to the back side position, the extension part 17 is bent to the back side of the base material 12 at the opening edge of the opening 14 in the first direction (see Figure 11(a)). By moving the second pressing part 78 along the opening edge of the opening 14 in the second direction from the front side position to the back side position, the extension part 17 is bent to the back side of the base material 12 at the opening edge of the opening 14 in the second direction (see Figure 14(a)).

[0050] By operating the corner actuation part 54 and moving the pressing part 58 from the inner position to the outer position, the pressing part 58 folds the extension part 17 back at the corner portion of the opening edge of the opening 14 and presses the extension part 17 against the back surface of the base material 12. As a result, the extension part 17 of a predetermined width formed between the two cuts N is wrapped around the back surface of the base material 12 from the corner portion of the opening edge of the opening 14 and attached to the back surface of the base material 12 by the adhesive layer (see Figure 8(b)). Here, the pressing part 58 moves diagonally so as it moves from the inner position away from the back surface of the base material 12 to the outer position, it approaches the back surface of the base material 12. Therefore, the extension part 17 can be properly folded back at the opening edge of the opening 14 and pressed against the back surface of the base material 12, and the extension part 17 can be neatly attached to the back surface of the base material 12.

[0051] By operating the first winding actuation part 62 and moving the first pressing part 66 from the inner position to the outer position, the first pressing part 66 folds the extension part 17 back at the opening edge of the opening 14 in the first direction and presses the extension part 17 against the back surface of the base material 12. As a result, the extension part 17 is wrapped around the back surface of the base material 12 from the opening edge of the opening 14 and attached to the back surface of the base material 12 by the adhesive layer (see Figure 11(b)). Here, the first pressing part 66 moves diagonally so as it moves from the inner position away from the back surface of the base material 12 to the outer position, it approaches the back surface of the base material 12. Therefore, the extension part 17 can be properly folded back at the opening edge of the opening 14 and pressed against the back surface of the base material 12, and the extension part 17 can be neatly attached to the back surface of the base material 12.

[0052] By operating the second winding actuation unit 72 to move the second winding arm 74 and the second pressing unit 78 from the inner position to the outer position, the second winding arm 74 folds the extension 17 back to the back surface of the base material 12 at the opening edge of the opening 14 in the second direction (see Figure 14(b)). By operating the pressing actuation unit 76 to move the second pressing unit 78 from the isolated position to the pressing position, the extension 17 is pressed against the back surface of the base material 12 (see Figure 14(c)). As a result, the extension 17 is wrapped around the back surface of the base material 12 from the opening edge of the opening 14 and attached to the back surface of the base material 12 by the adhesive layer. In the second winding actuation unit 70, since the second pressing unit 78 moves back and forth relative to the back surface of the base material 12 by the pressing actuation unit 76, the extension 17 can be neatly attached to the back surface of the base material 12 even if the opening edge of the opening 14 is curved on the back side.

[0053] The folding and joining process of the extension portion 17 by the corner wrapping portion 50, the first wrapping portion 60, and the second wrapping portion 70 is performed at the same time. After the folding and joining process of the extension portion 17 by the corner wrapping portion 50, the first wrapping portion 60, and the second wrapping portion 70 is performed, the pressing portion 58, the first pressing portion 66, and the second pressing portion 78 are returned to their front-side positions in the reverse order of the folding and joining process. In this way, the interior member 10 for vehicles is obtained by joining the extension portion 17 to the back surface of the base material 12 using the surface material processing device 20.

[0054] The surface material processing apparatus 20 moves the cutting blade 32 by the cutting blade moving unit 40 so that when forming a cut N with the cutting blade 32, the cut N is formed from a position close to the opening edge of the opening 14 in the extension portion 17 toward the end of the extension portion 17. By forming the cut N with the cutting blade 32 from a position close to the opening edge of the opening 14, tension is applied to the extension portion 17 toward the end when the cut N is being formed, allowing the cut N to be formed stably. Furthermore, by forming a cut N in the extension portion 17, when the extension portion 17 is folded back at the opening edge of the opening 14, it is possible to prevent appearance defects such as wrinkles caused by tension in the surface material 16. According to the surface material processing apparatus 20, the cut N formed in the extension portion 17 of the surface material 16 allows the surface material 16 to be wrapped neatly around the opening edge of the opening 14 in the base material 12. Furthermore, by using the surface material processing device 20, it is possible to obtain a vehicle interior member 10 in which the surface material 16 is neatly wrapped around the opening edge of the opening 14 in the base material 12.

[0055] In particular, by forming notches N in the extension portion 17 corresponding to the corner portion of the opening edge of the opening 14, when the extension portion 17 is folded back at the corner portion of the opening edge of the opening 14, it is possible to prevent wrinkles, sagging, and other appearance defects from occurring in the surface material 16. The notch forming portion 30 has two cutting blades 32 that form extension portions 17 of a predetermined width that are folded back at the corner portion of the opening 14, so that the extension portion 17 that is folded back at the corner portion of the opening edge and the extension portion 17 that is folded back at the opening edge in the first direction and the second direction can be separated. As a result, the extension portion 17 can be folded back separately for each opening edge extending in different directions. This makes it possible to wrap the surface material 16 around the opening edge of the opening 14 in the base material 12 with a good finish.

[0056] The surface material 16 according to this embodiment has an adhesive layer, but since no cuts N are formed when peeling off the release paper protecting the adhesive layer, the release paper will not tear starting from the cuts N, and the workability when layering the surface material 16 onto the base material 12 can be improved.

[0057] As mentioned above, the cutting blade 32 is an inclined blade that is inclined in one direction in the width direction (third direction). The cutting blade moving unit 40 is configured to move the cutting blade 32, which is positioned so that the tip of the inclined blade is close to the opening edge of the opening 14 when forming the cut N, from the front side to the back side of the base material 12. When the cutting blade 32 is moved from the front side to the back side of the base material 12, the inclination of the inclined blade allows for easy and stable formation of the cut N towards the end of the extension 17 from the tip of the inclined blade, which is inserted into a position close to the opening edge of the opening 14 in the extension 17.

[0058] The surface material processing device 20 is equipped with a position adjustment unit 36 ​​that adjusts the position of the tip of the cutting blade 32 between a direction approaching the opening edge of the opening 14 and a direction away from the opening edge. By adjusting the position of the tip of the cutting blade 32, it is possible to form a cut N of an appropriate length according to the length of the extension 17, the material of the surface material 16, the thickness of the base material 12, etc. This makes it possible to wrap the surface material 16 around the opening edge of the opening 14 in the base material 12 with a good finish.

[0059] The surface material processing device 20 is equipped with a support part 38 that rises together with the cutting blade 32 which is moved by the cutting blade moving part 40, and moves the extension part 17 to the back side of the base material 12. This prevents the extension part 17 from sagging and allows for the stable formation of the cut N in the extension part 17.

[0060] The surface material processing device 20 includes a pressing unit 58 that, after the cut N is formed, presses the extended portion 17 toward the back surface of the base material 12 from an oblique direction. By pressing the extended portion 17 toward the back surface of the base material 12 from an oblique direction with the pressing unit 58, the extended portion 17 can be folded back from the opening edge toward the back surface of the base material 12 while applying tension. This allows the surface material 16 to be neatly wrapped around the opening edge of the opening 14 in the base material 12. In addition, since the pressing unit 58 moves between the two cutting blades 32, the extended portion 17 of a predetermined width formed by the two cutting blades 32 can be appropriately folded back to the corner portion of the opening 14. The space between the two cutting blades 32 can be effectively utilized as the positioning space for the pressing unit 58.

[0061] (Example 1 of modifications to the notched section and corner wrapping section) Modify Example 1 of the notch forming section 30 and corner wrapping section 50 will be described with reference to Figures 17 to 20. In the description of Modify Example 1, components similar to those in the previously described embodiment are denoted by the same reference numerals and their descriptions are omitted. Furthermore, the components of the previously described embodiment can be applied to matters not described in Modify Example 1 below.

[0062] As shown in Figure 17, the notch forming section 30 includes a support section 138 that rises together with the cutting blade 32, which is moved by the cutting blade moving section 40. The support section 138 is mounted between the two cutting blade arms 46 of the cutting blade moving section 40 and is positioned between the two cutting blades 32. The support section 138 has a raised section 138b in the center of the direction perpendicular to the third direction between the two cutting blades 32, and lower sections 138a, which are lower than the raised section 138b, are provided on both sides of the raised section 138b. The raised section 138b of the support section 138 is positioned at a distance from each of the two cutting blades 32 (see Figures 18 and 19). The upper end of the raised section 138b is positioned lower than the tip of the cutting blade 32. Furthermore, the outer edge of the support portion 138 in the third direction is positioned at the same location as the tip of the cutting edge 32, or at a position further outward in the third direction than the tip.

[0063] As the support portion 138 rises together with the cutting blade 32, it contacts the extension portion 17 of the surface material 16 at the timing after the tip of the cutting blade 32 has come into contact with the extension portion 17, pushing the extension portion 17 upward toward the back side of the base material 12. When the support portion 138 rises together with the cutting blade 32, the raised portion 138b protrudes above the back surface of the base material 12 through the opening 14, holding the extension portion 17 of the surface material 16, which has been moved to the back side of the base material 12, in an upright position. In this way, the extension portion 17 is mainly supported by the raised portion 138b of the support portion 138 between the two cutting blades 32. Furthermore, when the support portion 138 rises together with the cutting blade 32, the lower portion 138a rises to the opening surface of the opening 14 and is set so as not to protrude above the back surface of the base material 12, holding the base of the extension portion 17 between the opening edge of the opening 14 and the lower portion 138a.

[0064] In the embodiment described above, the support portion 38 was lowered and retracted to prevent interference between the support portion 38 and the pressing portion 58 before the extension portion 17 was pressed toward the back surface of the base material 12 by the corner wrapping portion 50. However, in Modified Example 1, by modifying the shape of the support portion 138 and the pressing portion 158 (described later), the support portion 138 remains raised when the extension portion 17 is pressed toward the back surface of the base material 12 by the corner wrapping portion 50 (see Figure 20). Thus, in Modified Example 1, the support portion 138 supports the extension portion 17 toward the back surface of the base material 12 after the extension portion 17 has been moved toward the back surface of the base material 12 and until the extension portion 17 is supported by the pressing portion 158. The support portion 138 is adjustable in position in a third direction.

[0065] As shown in Figure 17, the corner wrapping portion 50 includes a pressing portion 158 that presses the extended portion 17 of the surface material 16 toward the back surface of the base material 12 after the cut N is formed by the cutting blade 32. The pressing portion 158 is movably positioned between the two cutting blades 32. The pressing portion 158 has a first pressing portion 158a that moves between the support portion 138 and one of the cutting blades 32 when pressing the extended portion 17 toward the back surface of the base material 12, and a second pressing portion 158b that moves between the support portion 138 and the other cutting blade 32 (see Figures 18 and 19). The first pressing portion 158a and the second pressing portion 158b are connected to each other. Specifically, the pressing portion 158 is divided into a first pressing portion 158a and a second pressing portion 158b, with a pressing recess 159 formed in the center in a direction perpendicular to the third direction, and its tip is also divided into a first pressing portion 158a and a second pressing portion 158b.

[0066] The pressing recess 159 has a width greater than the width of the raised portion 138b of the support portion 138 in a direction perpendicular to the third direction, and is formed so that the raised portion 138b can be inserted through it. When the extension portion 17 is pressed toward the back surface of the base material 12, the raised portion 138b is accommodated in the pressing recess 159 (see Figure 20). In addition, the first pressing portion 158a and the second pressing portion 158b are set to dimensions that allow them to pass between the support portion 138 and the cutting blade 32, and when the extension portion 17 is pressed toward the back surface of the base material 12, they move from the inside to the outside in the third direction, passing above the lower portion 138a of the support portion 138.

[0067] The pressing surfaces, which are the lower surfaces of the first pressing portion 158a and the second pressing portion 158b, are formed to match the shape of the back surface of the corner portion at the opening edge of the opening 14. The pressing surfaces of the first pressing portion 158a and the second pressing portion 158b have a portion that slopes downward from the inside to the outside in the third direction, and a portion that is recessed to match the protrusion of the opening edge of the opening 14 of the base material 12, so as the back surface of the base material 12 slopes downward from the inside to the outside in the third direction.

[0068] The wrapping process of the surface material 16 in modification example 1 will now be explained. The cutting blade 32 rises from the front side position to the back side position through the opening 14, forming a cut N in the extension portion 17 (see Figures 20(a) and (b)). During the formation of the cut N by the cutting blade 32, a support portion 138 positioned between the two cutting blades 32 contacts the extension portion 17 from the front side, and the extension portion 17 between the cuts N formed by the two cutting blades 32 is supported from the front side by the support portion 138 while the formation of the cut N progresses. By the time the cutting blade 32 rises to the back side position, the cut N has been formed by the cutting blade 32 to the end of the extension portion 17, and the extension portion 17 between the two cutting blades 32 is held in a folded state on the back side of the base material 12 by the support portion 138 which extends in the front-back direction along the opening edge of the opening 14 (see Figure 20(c)). At this time, the support portion 138 remains raised without descending, supporting the extension portion 17. The two cutting blades 32 also remain raised without descending.

[0069] By further moving the raised pressing portion 158 from the inner position to the outer position, the pressing portion 158 folds the extension portion 17 supported by the support portion 138 back at the corner portion of the opening edge of the opening 14 and presses the extension portion 17 against the back surface of the base material 12 (see Figure 20(d)). At this time, the first pressing portion 158a moves between the support portion 138 and one of the cutting blades 32, the second pressing portion 158b moves between the support portion 138 and the other cutting blade 32, and the raised portion 138b of the support portion 138 is housed in the pressing recess 159, so that the support portion 138 and the pressing portion 158 do not interfere with each other, and each of the edges of the extension portion 17 in the direction perpendicular to the third direction is pressed against the back surface of the base material 12 by the first pressing portion 158a and the second pressing portion 158b. As a result, the extension portion 17 of a predetermined width formed between the two cuts N is wrapped around the back surface of the base material 12 from the corner portion of the opening edge of the opening 14 and attached to the back surface of the base material 12 by the adhesive layer. Here, the pressing portion 158 moves diagonally from an inner position away from the back surface of the base material 12 to an outer position, approaching the back surface of the base material 12. Therefore, the extension portion 17 can be properly folded back at the opening edge of the opening 14 and pressed against the back surface of the base material 12, and the extension portion 17 can be neatly attached to the back surface of the base material 12.

[0070] As described above, the support portion 138 moves the extension portion 17 to the back side of the base material 12, then supports the extension portion 17 on the back side of the base material 12, and the pressing portion 158 presses the extension portion 17, which is supported by the support portion 138, toward the back side of the base material 12. In this way, the extension portion 17 is maintained in a state supported by the support portion 138 and the pressing portion 158, so that the upright extension portion 17 does not fall over in an unintended position, and the extension portion 17 can be neatly attached to the back side of the base material 12. Furthermore, since the pressing portion 158 has a first pressing portion 158a that moves between the support portion 138 and one of the cutting blades 32, and a second pressing portion 158b that moves between the support portion 138 and the other cutting blade 32, the edges of the extension portion 17 in the direction perpendicular to the third direction can be pressed against the back surface of the base material 12 by the first pressing portion 158a and the second pressing portion 158b. This suppresses the occurrence of lifting and wrinkling of the edges of the extension portion 17, and allows the extension portion 17 to be neatly attached to the back surface of the base material 12.

[0071] (Example 2 of modifications to the cut-out section and corner wrapping section) Referring to Figures 21 to 24, a modified example 2 of the notch forming section 30 and corner wrapping section 50 will be described. Modified example 2 differs from modified example 1 in that the support section 238 has a recessed lower step section 238a in the center in the direction perpendicular to the third direction, and the higher step section 238b is divided into two. In addition, the support section 238 of modified example 2 is configured to support both edges of the extension section 17 of the surface material 16. The pressing section 258 of modified example 2 is formed to be smaller than the width of the lower step section 238a in the direction perpendicular to the third direction, and can be inserted between the two higher step sections 238b of the support section 238. In modified example 2, as in modified example 1, by further moving the pressing section 258 from the inner position to the outer position, the pressing section 258 folds the extension section 17 supported by the support section 238 back at the corner portion of the opening edge of the opening 14 and presses the extension section 17 against the back surface of the base material 12. Even in Modification Example 2, the extension portion 17 is supported by the support portion 238, which prevents the upright extension portion 17 from falling over and allows the extension portion 17 to be neatly attached to the back surface of the base material 12. In the description of Modification Example 2, the same reference numerals are used for components similar to those in the previously described embodiment and Modification Example 1, and their descriptions are omitted. Furthermore, for matters not described in the following description of Modification Example 2, the previously described embodiment or Modification Example 1 can be applied.

[0072] (Variations of the appendix in Volume 2) A modified example of the second winding portion 70 will be described with reference to Figures 25 to 27. In the embodiment described above, the extension portion 17 was folded back to the back surface of the base material 12 at the opening edge of the opening 14 in the second direction by the second winding arm 74, but in the modified example, the extension portion 17 is folded back to the back surface of the base material 12 at the opening edge of the opening 14 in the second direction by the second pressing portion 178. In the description of the modified example, components that are the same as those in the embodiment described above are denoted by the same reference numerals and their description is omitted. Furthermore, the configuration of the embodiment described above can be applied to matters not described in the following modified example.

[0073] The wrapping process of the surface material 16 by the modified second wrapping section 70 is as follows: By operating the base operating section 52, the second pressing section 178 is moved from the front position to the back position through the opening 14 (see Figure 25(a)). At this time, the lower tip of the second pressing section 178 is positioned to match the back surface of the base material 12 (see Figures 25(b) and 27(a)). By operating the second wrapping operating section 72 and moving the second wrapping arm 74 and the second pressing section 178 from the inner position to the outer position, the extension section 178 folds the extension section 17 back to the back surface of the base material 12 at the opening edge of the opening 14 in the second direction (see Figures 26(a) and 27(b)). The pressing actuation unit 76 is activated to move the second pressing unit 178 from the isolation position to the pressing position, thereby pressing the extension unit 17 against the back surface of the base material 12 (see Figures 26(b) and 27(c)).

[0074] The pressing surface of the second pressing portion 178 is formed to match the shape from the opening edge of the opening 14 of the base material 12 to the area where the extension portion 17 is attached. As a result, the extension portion 17 is wrapped around the back surface of the base material 12 from the opening edge of the opening 14 and attached to the back surface of the base material 12 by the adhesive layer. In the second wrapping portion 70, the second pressing portion 178 moves back and forth relative to the back surface of the base material 12 by the pressing actuation portion 76, so even if the opening edge of the opening 14 is curved on the back side, the extension portion 17 can be attached to the back surface of the base material 12 with a good finish. In addition, when the second pressing portion 178 is moved from the inner position to the outer position, the second pressing portion 178 moves along the opening edge of the opening 14 of the base material 12, so that the lifting of the extension portion 17 that has been folded back on the back surface of the base material 12 can be suppressed, and the extension portion 17 can be attached to the back surface of the base material 12 with a good finish.

[0075] (Another example of the pressing surface of the pressing part) As shown in Figure 28, in another example, the pressing surface of the extension 17 in the pressing portion 358 has a bumpy portion 359 in which bumps and ridges are arranged in a third direction (pressing direction) of the pressing portion 358. The bumpy portion 359 is set such that the resistance when moving away from the opening edge (edge) of the opening 14 of the base material 12 in the third direction (pressing direction) is greater than the resistance when moving towards the opening edge (edge) of the opening 14 of the base material 12. The bumpy portion 359 has alternating grooves and ridges that extend in a direction perpendicular to the third direction on the pressing surface of the pressing portion 358. The surface of the ridge of the bumpy portion 359 in the direction of travel during pressing extends at an angle α that is perpendicular or obtuse to the third direction. Therefore, when the pressing portion 358 comes into contact with the extension portion 17 and resistance is generated between it and the extension portion 17, the protrusions of the uneven portion 359 are more likely to catch on the extension portion 17 when moving in the third direction away from the opening edge of the opening 14 of the base material 12. As a result, when the pressing portion 358 attaches the extension portion 17 to the back surface of the base material 12, the uneven portion 359 can pull the extension portion 17 and stretch it out, allowing the extension portion 17 to be attached to the back surface of the base material 12 with a good finish.

[0076] Furthermore, the surface of the ridges of the uneven portion 359 in the direction of travel when retracted extends at an angle β that is acute with respect to the third direction. Therefore, when the pressing portion 358 is in contact with the extension portion 17 and resistance is generated between it and the extension portion 17, the ridges of the uneven portion 359 are less likely to catch on the extension portion 17 when moving in the direction approaching the opening edge of the opening 14 of the base material 12 in the third direction. This prevents the uneven portion 359 from catching on the extension portion 17 when the pressing portion 358 retracts after attaching the extension portion 17 to the back surface of the base material 12. In the description of the alternative example, the same reference numerals are used for components similar to those in the embodiment described above, and their description is omitted. Also, the embodiment described above can be applied to matters not mentioned in the description of the alternative example below.

[0077] (Example of change) The present invention is not limited to the aforementioned matters, but may also be applied as follows, for example. Furthermore, the present invention is not limited to the embodiments and the following specific examples of modifications. (1) In this embodiment, the cutting blade was moved in the front-to-back direction to form a cut from a position close to the opening edge of the extension towards the end of the extension. However, the invention is not limited to this, and the cutting blade may also be moved horizontally from the outside to the inside in the third direction to form a cut from a position close to the opening edge of the extension towards the end of the extension. (2) In the embodiment, pneumatic cylinders were used as the first cutting blade operating part, second cutting blade operating part, base operating part, corner operating part, first winding operating part, second winding operating part, and pressing operating part. However, the invention is not limited to these, and fluid pressure cylinders that operate with a fluid such as oil, motors, or other driving means can be used. (3) In this embodiment, two cutting blades are arranged in parallel, but the invention is not limited to this, and there may be one cutting blade, or three or more cutting blades may be arranged in parallel. (4) In the embodiment, the surface material was folded back at the opening edge of an opening provided in the base material and attached to the back surface of the base material. However, the edge of the base material from which the surface material is folded back is not limited to the opening edge, but may be the outer peripheral edge of the base material. When forming a cut in the extended portion of the surface material that extends from the outer peripheral portion of the base material, by moving the cutting blade to form the cut from a position close to the outer peripheral portion of the extended portion toward the end of the extended portion, it is possible to make it less likely for appearance defects such as wrinkles and looseness due to excess surface material to occur when the extended portion is folded back at the outer peripheral portion of the base material. (5) The uneven surface of the pressing portion described in the other example may be applied to the pressing surface of the first pressing portion of the first wrapping portion. In this case, the pressing surface of the extension portion of the first pressing portion is provided with an uneven surface in which the unevenness is continuous in the pressing direction of the first pressing portion, and it is preferable to set the resistance when moving the uneven surface away from the edge of the base material in the pressing direction to be greater than the resistance when moving towards the edge. (6) The uneven surface of the pressing portion described in the other example may be applied to the pressing surface of the second pressing portion of the second wrapping portion. In this case, the pressing surface of the extension portion of the second pressing portion is provided with an uneven surface in which the unevenness is continuous in the pressing direction of the second pressing portion, and it is preferable to set the resistance when the uneven surface moves away from the edge of the base material in the pressing direction to be greater than the resistance when it moves towards the edge.
