The present invention relates to a method of manufacturing an interior part and a manufacturing apparatus thereof, and more specifically, a method of manufacturing an interior part formed by press-bonding a base material having an undercut portion and a skin material shaped into a shape corresponding to the base material. And its manufacturing apparatus.

For example, an automobile interior component (for example, an instrument panel or the like) is formed by adhering a skin material having a soft foam layer to the surface of a base material made of a hard synthetic resin. By forming a stitch pattern or the like on the surface material, the decorating property of the interior parts is enhanced. A method of manufacturing such an interior component is disclosed in Patent Document 1, for example.

That is, according to the method of manufacturing an interior part disclosed in Patent Document 1, as shown in FIG. 11(A), a stitch with a thread is formed on a skin material 101 formed in a predetermined design shape by sewing means such as a sewing machine. A pattern 102 is formed. Then, the skin material 101 in which the filling material 103 is attached in the vicinity of the thin portion 101a thinned at the time of molding, and the base material 104 molded separately from the skin material 101 are set in a press die not shown. Adhesive means such as an adhesive is applied to one or both of the skin material 101 and the base material 104. Then, as shown in FIGS. 11B and 11C, the base material 104 and the skin material 101 are pressure-bonded by closing the press die, and the base material 104 and the skin material 101 are bonded together by an adhesive means.

In the case of including 101b and 104a, the undercut portion 101b of the skin material 101 might interfere with the base material 104 when the base material 104 and the skin material 101 are pressure-bonded by closing the press die. Therefore, after the undercut portion 101b of the skin material 101 is gripped and passed through the base material 104 in a state where it is forcibly opened in a direction that does not interfere with the base material 104 (direction of arrow Q), the undercut of the skin material 101 is performed. A method of pressing the undercut portion 101b of the skin material 101 to the undercut portion 104a of the base material 104 using a slide core or the like (not shown) that opens the portion 101b and moves in a direction different from the mold closing direction has been studied. ing.

Next, as shown in FIGS. 3B and 4, the gripping portion 51 is moved in the direction of the arrow L1 while gripping the gripping flange portion 32 to move the undercut portion 31 of the skin material 3 to the base material 2. After retreating to a retreat position that does not interfere with, the upper jig 11 on which the base material 2 is set is lowered to press the base material 2 onto the skin material 3 (step S3). Since the other jig (lower jig) 12 has a textured shape (not shown) formed on the contact surface of the skin material 3 and is vacuum-sucked, when the base material 2 is pressure-bonded to the skin material 3, The grain pattern is transferred to the surface of the skin material 3. When the undercut portion 31 of the skin material 3 is retracted to the retracted position, the slide core 4 is waiting at the retracted position, so that the undercut portion 31 of the skin material 3 does not interfere with the slide core 4. Absent.

Next, as shown in FIG. 3C and FIG. 4, the undercut portion 31 of the skin material 3 is moved to the undercut portion 31 by moving the grip portion 51 in the direction of arrow L2 while gripping the grip flange portion 32. After returning to the normal position where it is crimped to the undercut portion 21, the vacuum suction of the lower jig 12 and the grip portion 51 is turned off, and the clamp device 8 is opened (step S4). As described above, after the undercut portion 31 of the skin material 3 is returned to the normal position, the grip flange portion 32 gripped by the grip portion 51 is opened, so that the undercut portion 21 of the base material 2 is undercut by the skin material 3. The positional deviation of the cut portion 31 can be greatly reduced. If vacuum suction of the upper jig 11 is possible, vacuum suction of the lower jig 12 is turned off, and then vacuum suction of the upper jig 11 is turned on.

Next, the slide core 4 is moved to the forward position, and the undercut portion 31 of the skin material 3 is pressure-bonded to the undercut portion 21 of the base material 2 (step S5). Since the slide core 4 has a textured shape (not shown) formed on the contact surface of the skin material 3 and is vacuum-sucked, the texture pattern is transferred to the undercut portion 31 of the skin material 3. Next, after the vacuum suction of the slide core 4 is turned off and the slide core 4 is moved to the retracted position, the upper jig 11 is raised to bring the jig into an opened state, and then the interior component W is taken out (step S6). When the upper jig 11 is vacuum-sucked, the vacuum jig is turned off and then the upper jig 11 is lifted. The interior part W can be manufactured according to the above steps.

<Method of reducing creases when retracting the undercut part of the skin material>
Next, a method for reducing breakage wrinkles when the undercut portion of the skin material is retracted will be described with reference to FIGS. FIG. 5 shows an operation explanatory diagram when the second undercut portion of the skin material is retracted to the retracted position in the vacuum crimping jig shown in FIG. FIG. 6 shows an explanatory diagram of the change in the circumferential length at the bent portion of the skin material shown in FIG. FIG. 7 shows a cross-sectional view of a comparative example in which the second undercut portion of the skin material shown in FIG. 5 is retracted to the retracted position. FIG. 8 shows an explanatory diagram of changes in the circumferential length at the bent portion of the skin material in the comparative example shown in FIG. 7.

As shown in FIGS. 5 and 6, the gripping mechanism 5 grips the gripping flange portion 32 and moves the gripping flange portion 32 in the direction of the arrow L1 to move the second undercut portion 31B of the skin material 3 from the regular position M to the retracted position N. The bent portion 33B of the skin material 3 that bends when retracted starts to curve from the general portion 34 that does not form a negative angle with respect to the jig opening/closing direction (K) of the crimping jig 10 to the undercut portion 31B of the skin material 3. It is preferable to form the bending start portion W1. As a result, as shown in FIGS. 7 and 8, the bending angle α (α1<α2) in the bending portion 33B of the skin material 3 is set by forming the bending portion 33C at the curved vertex W2 that curves to the undercut portion 31C. It can be made relatively small. Further, the bending apex W2 has a smaller curvature than the bending start portion W1, and when it is bent, a local deep wrinkle is generated, but the bending start portion W1 has a large curvature and is gently bent when bent. The creases are less likely to remain. The position of the bent portion 33B of the skin material 3 is set by the position of the boundary portion 123 of the lower jig 12 with the slide core 4B. Further, the gripping mechanism 5 grips the gripping flange portion 32 and moves the gripping flange portion 32 in the direction of the arrow L2, and the undercut portion 31B of the skin material 3 returned to the regular position M is in a direction different from the jig opening/closing direction (K) ( The slide core 4B moving forward to L3) is pressure-bonded to the undercut portion 21 of the base material 2.

Further, as shown in FIGS. 5 and 6, the plate thickness t1 of the bending start portion W1 that becomes the bent portion 33B of the skin material 3 may be formed thinner than the plate thickness t2 of the undercut portion 31B (t1<t2). preferable. Thus, when the undercut portion 31B is retracted from the regular position M to the retracted position N, the sum of the amount of contraction on the front surface side of the skin material and the amount of extension on the back surface side of the skin material in the bent portion 33B (amount of change in circumferential length). ) D1, as shown in FIGS. 7 and 8, the amount of shrinkage on the front surface side of the skin material and the elongation on the back surface side of the skin material when the bent portion 33C is formed at the curved vertex W2 that curves to the undercut portion 31C. The sum can be significantly reduced from the sum (amount of change in circumference) d2. The effect of reducing the bending angle in the bent portion 33B of the skin material 3 and the effect of reducing the amount of change in the circumferential length of the front and back surfaces of the skin material in the bent portion 33B act synergistically, and the bent wrinkles remaining in the bent portion 33B of the skin material 3 Can be significantly reduced.

<How to reduce the adhesion failure of the side wall flange adjacent to the undercut of the skin>
Next, a method of reducing the adhesion failure of the side wall flange portion formed adjacent to the undercut portion of the skin material will be described with reference to FIGS. 9 and 10. FIG. 9 shows a partial perspective view of the skin material of the interior part shown in FIG. 1, including the side wall flange portion formed adjacent to the undercut portion. FIG. 10 shows a schematic sectional view of a crimping jig for crimping the side wall flange portion of the skin material shown in FIG. 9 to the base material. FIG. 10(A) shows a cross-sectional view in which the base material is lowered and the baffle plate is advanced after the undercut portion of the skin material is retracted to the retracted position, and in FIG. 10(B), the baffle plate is the base. FIG. 10D shows a cross-sectional view in which the undercut portion of the skin material is returned to the normal position with the adhesive surface of the material shielded, and FIG. 10C shows a cross-sectional view in which the baffle plate is retracted. ) Shows a cross-sectional view in which the side wall flange slide core advances and the side wall flange portion of the skin material is pressed against the adhesive surface of the base material.

For example, as shown in FIG. 9 and FIG. 10, when the side wall flange portion 35 which is adjacent to the undercut portion 31 of the skin material 3 and intersects at about 90 degrees is formed, the undercut portion 31 is moved to the retracted position. After returning to the normal position after being retracted to, the side wall flange portion 35 comes into contact with the adhesive surface 22 of the base material 2, causing a wrinkle in the side wall flange portion, and the side wall of the base material 2 with respect to the adhesive surface 22. There is a risk that the adhesion position of the flange portion 35 may vary, resulting in poor adhesion.

Then, as a result of diligent study, a side wall flange portion 35 formed adjacent to the undercut portion 31 of the skin material 3 is formed on one jig (upper jig) 11 of the crimping jig 10 for setting the base material 2. The baffle plate 71 is formed so as to shield the adhesive surface 22 of the base material 2 to be pressure-bonded with, and the gripping mechanism 5 (see FIG. 1) grips the gripping flange part 32 to remove the undercut part 31 of the skin material 3. Since the baffle plate 71 shields the adhesive surface 22 of the base material 2 until it returns to the normal position, it is possible to reduce the adhesive failure of the side wall flange portion 35. The specific method will be described below.

As shown in FIG. 10A, the shield device 7 including the baffle plate 71 that shields the adhesive surface 22 of the base material 2 and the drive cylinder 72 that advances and retracts the baffle plate 71 is provided on the side wall portion 111 of the upper jig 11. Attach to. Then, the gripping mechanism 5 shown in FIGS. 1 and 3 grips the gripping flange portion 32 on which the positioning projection 321 is formed and pulls in the direction of arrow P1 to retract the undercut portion 31 of the skin material 3. After retracting to the position, the drive cylinder 72 is extended to advance the baffle plate 71 in the direction of arrow P2, and the baffle plate 71 shields the adhesive surface 22 of the base material 2. Then, the upper jig 11 is lowered so that the jig is closed.

Next, as shown in FIG. 10B, the grip flange portion 32 is moved in the direction of arrow P3, and the undercut portion 31 of the skin material 3 is returned to the regular position. At this time, the baffle plate 71 that shields the adhesive surface 22 of the base material 2 is inserted between the side wall flange portion 35 and the adhesive surface 22 of the base material 2 while slightly expanding the side wall flange portion 35. Therefore, it is possible to avoid contact between the side wall flange portion 35 and the adhesive surface 22 of the base material 2.

Next, as shown in FIG. 10C, the driving cylinder 72 is shortened, and the baffle plate 71 inserted between the side wall flange portion 35 and the bonding surface 22 of the base material 2 is retracted to the upper jig side. After that, as shown in FIG. 10D, the side wall flange slide core 4C is advanced to press the side wall flange portion 53 onto the adhesive surface 22 of the base material 2. According to the above method, it is possible to prevent the side wall flange portion 35 from coming into contact with the adhesive surface 22 of the base material 2 during the process of returning the undercut portion 31 of the skin material 3 to the retracted position and then returning to the regular position. Therefore, it is possible to reduce the adhesion failure that causes the side wall flange portion 35 to be broken or wrinkled.

<Effect>
As described above in detail, according to the method for manufacturing the interior component according to the present embodiment, the grip flange portion 32 extends in the undercut portion 31 of the skin material 3 in the direction away from the base material 2. Further, in the other jig (lower jig) 12 of the crimping jig 10 for setting the skin material 3, a direction (direction of arrow L) different from the jig opening/closing direction (direction of arrow K) of the crimping jig 10. ) To move the undercut portion 31 of the skin material 3 into pressure contact with the undercut portion 21 of the base material 2, and a gripping mechanism 5 that grips the gripping flange portion 32 and moves back and forth in substantially the same direction as the slide core 4. When the slide core 4 is in the retracted position with the crimping jig 10 in the jig open state, the grasping mechanism 5 grasps the grasping flange portion 32 and the undercut portion 31 of the skin material 3 to the base material 2. Since it is retracted to the retracted position where it does not interfere, when the base material 2 and the skin material 3 are pressure bonded by closing the pressure bonding jig 10, it is possible to avoid the undercut portion 31 of the skin material 3 from interfering with the base material 2.

In addition, the gripping mechanism 5 grips the gripping flange portion 32 to remove the undercut portion 31 of the skin material 3 from the base material 2 before the slide core 4 moves to the forward position in the jig closed state of the crimping jig 10. Since the slide core 4 is returned to the regular position where it is crimped to the undercut portion 21, the undercut portion 31 of the skin material 3 that has returned to the regular position can be crimped to the undercut portion 21 of the base material 2 by advancing the slide core 4. Therefore, the positional deviation between the undercut portion 21 of the base material 2 and the undercut portion 31 of the skin material 3 can be reduced.

Therefore, according to the present embodiment, it is possible to provide a method of manufacturing an interior component that can reduce the positional deviation of the undercut portion 31 of the skin material 3 that is pressure-bonded to the undercut portion 21 of the base material 2.

Further, according to the present embodiment, the gripping flange portion 32 is provided with the positioning convex portion 321 that projects toward the front surface side of the skin material 3 and has the side wall 321S formed in a taper shape. A positioning recess 511 having a tapered side wall 511S which can be engaged with the positioning projection 321 when gripping the portion 32 and can be separated from the positioning projection 321 when opening the grip flange portion 32. Since the gripping unit 5 has the gripping unit 51, when the gripping mechanism 5 grips the gripping flange unit 32 and retracts the undercut portion 31 of the skin material 3 to a retracted position that does not interfere with the base material 2, positioning with the positioning projection 321 is performed. The undercut portion 31 of the skin material 3 can be more accurately retracted to the retracted position by easily engaging with the recess portion 511.

Further, when the gripping mechanism 5 grips the gripping flange portion 32 and returns the undercut portion 31 of the skin material 3 to the normal position and then opens the gripping flange portion 32, the positioning convex portion 321 and the positioning concave portion 511. Can be easily separated from each other, and deformation and displacement of the undercut portion 31 of the skin material 3 when opening the undercut portion 31 of the skin material 3 returned to the regular position can be avoided. Therefore, it is possible to further reduce the positional deviation of the undercut portion 31 of the skin material 3 that is pressure-bonded to the undercut portion 21 of the base material 2.

Further, according to the present embodiment, the suction hole 511H connected to the vacuum pump 6 is formed in the positioning recess 511, and when the vacuum suction is performed via the suction hole 511H, the positioning projection 321 and the positioning recess are formed. Since it engages with 511, engagement or separation of the positioning projection 321 and the positioning recess 511 can be easily switched based on ON/OFF operation of vacuum suction. Therefore, the grip portion 51 of the grip mechanism 5 can be downsized and simplified, and the grip portion 51 can be advanced and retracted by a simpler driving device to move the undercut portion 31 of the skin material 3 between the retracted position and the regular position. it can.

Further, since the grip portion 51 can be downsized, the grip flange portion 32 extending from the undercut portion 31 of the skin material 3 can be reduced, and the usage amount of the skin material 3 can be reduced. As a result, it is possible to further reduce the positional deviation of the undercut portion 31 of the skin material 3 that is pressure-bonded to the undercut portion 21 of the base material 2, while reducing the cost associated with the reduction in the amount of use of the skin material 3.

In addition, according to the present embodiment, the bent portion 33B of the skin material 3 that is bent when the grip mechanism 5 grips the grip flange portion 32 and retracts the undercut portion 31B of the skin material 3 to the retracted position, the crimp cure is performed. Since the bending start portion W1 that starts to bend from the general portion 34 that does not form a negative angle with respect to the jig opening/closing direction (direction of arrow K) of the tool 10 to the undercut portion 31B of the skin material 3, the bending portion 33B is undercut. The bending angle α1 at the bending portion 33B of the skin material 3 can be made relatively smaller than that at the apex W2 that bends to the cut portion 31B, and local creases can be avoided.

Further, since the plate thickness t1 of the bending start portion W1 that becomes the bent portion 33B of the skin material 3 is formed thinner than the plate thickness t2 of the undercut portion 31B, the amount of shrinkage of the bent portion 33B on the surface side of the skin material and the back surface of the skin material are reduced. The sum (amount of change in circumferential length) d1 with the amount of elongation on the side can be reduced. The effect of reducing the bending angle α1 at the bent portion 33B of the skin material 3 and the effect of reducing the circumferential length change amount d1 between the front and back surfaces of the skin material at the bent portion 33B synergistically act on the bent portion 33B of the skin material 3. The remaining creases can be greatly reduced. As a result, the skin that is crimped to the undercut portion 21 of the base material 2 while significantly reducing the creases of the bent portion 33B of the skin material 3 that bends when the undercut portion 31B of the skin material 3 is retracted to the retracted position. The positional deviation of the undercut portion 31B of the material 3 can be reduced.

Further, according to the present embodiment, the side wall flange formed adjacent to the undercut portion 31 of the skin material 3 on one jig (upper jig) 11 of the crimping jig 10 for setting the base material 2. The baffle 71 is formed so as to shield the adhesive surface 22 of the base material 2 to which the portion 35 is crimped, and the gripping mechanism 5 grips the gripping flange portion 32 to return the undercut portion 31 of the skin material 3 to the normal position. Until then, since the baffle plate 71 shields the adhesive surface 22 of the base material 2, the side wall flange portion 35 of the skin material 3 is returned while the undercut portion 31 of the skin material 3 retracted to the retracted position is returned to the regular position. The baffle plate 71 can prevent the sticking to the adhesive surface 22 of the base material 2 and the formation of wrinkles or the like in the side wall flange portion 35. As a result, the undercut of the base material 2 is avoided while avoiding the wrinkles and the like of the side wall flange portion 35 caused by the side wall flange portion 35 adjacent to the undercut portion 31 of the skin material 3 sticking to the adhesive surface 22 of the base material 2. It is possible to reduce the positional deviation of the undercut portion 31 of the skin material 3 that is pressure bonded to the portion 21.

According to the manufacturing apparatus 50 for the present interior part, which is another embodiment, the undercut portion 31 of the skin material 3 has a grip flange portion 32 extending in a direction away from the base material 2, and the skin material 3 In the other jig (lower jig) 12 of the crimping jig 10 for setting, the surface material is moved forward and backward in a direction (arrow L) different from the jig opening/closing direction (arrow K direction) of the crimping jig 10. The slide core 4 for crimping the undercut portion 31 of No. 3 to the undercut portion 21 of the base material 2 and the grip flange portion 32 are gripped and moved back and forth in substantially the same direction as the slide core 4 to open the jig of the crimp jig 10. When the slide core 4 is in the retracted position in this state, the grip flange portion 32 is gripped to retract the undercut portion 31 of the skin material 3 to a retracted position that does not interfere with the base material 2, and the jig of the crimping jig 10 is closed. Before the slide core 4 moves to the forward position in this state, the gripping mechanism 5 which grips the gripping flange portion 32 and returns the undercut portion 31 of the skin material 3 to the undercut portion 21 of the base material 2 to the normal position. And equipped. Therefore, when the base material 2 and the skin material 3 are pressure bonded by closing the pressure bonding jig 10, it is possible to avoid the undercut portion 31 of the skin material 3 from interfering with the base material 2. Further, by moving the slide core 4 forward, the undercut portion 31 of the skin material 3 that has returned to the normal position can be pressed against the undercut portion 21 of the base material 2, and the undercut portion 21 of the base material 2 and the skin The positional deviation of the material 3 from the undercut portion 31 can be reduced.

Therefore, according to the other embodiment, it is possible to provide the interior component manufacturing apparatus 50 capable of reducing the positional deviation of the undercut portion 31 of the skin material 3 which is pressure-bonded to the undercut portion 21 of the base material 2.
