Description

  The present invention relates to a skin material bonding apparatus for vehicle interior parts for bonding a skin material to a surface formed by a convex curved surface of a core material.

  First, a vehicle interior product to be bonded by the skin material bonding apparatus according to the present invention will be described. As such a vehicle interior product, there is a pillar trim T shown in FIGS. 6 and 7. The pillar trim T has a plate shape with a substantially arc-shaped cross section, and includes a core material T1 having a predetermined strength and a skin material T2 bonded and fixed to a surface T1a having a convex curved surface shape of the core material T1. Has been. The skin material T2 may be composed of only a single skin as in this example, or may be composed of a skin and a foam layer that are bonded and fixed to each other. In the latter case, the foam layer is the core material T1. The surface T1a is adhesively fixed.

  Conventionally, when the skin material T2 is bonded to the core material T1, the bonding is performed manually.

  Manual bonding is inefficient. Therefore, mechanization of the bonding work has been demanded. However, when the surface T1a of the core material T1 to which the skin material T2 is to be bonded has a convex curved surface shape like the pillar trim T, the skin material T2 is evenly distributed over the entire surface T1a of the core material T1 by a machine. It is difficult to press with force, and there is a possibility that an adhesion failure portion may occur in a part of the skin material T2. For this reason, the apparatus which adhere | attaches the skin material T2 on the surface T1a of the core material T1 which makes a convex curved surface like the pillar trim T has not been realized so far.

The present invention has been made in view of the above circumstances, and is intended to bond and fix the skin material to the core material of the vehicle interior product in which the skin material is bonded and fixed to the convex curved surface of the core material. a skin material bonding device for a vehicle interior trim, and the upper support portion for supporting the core material in a state of being positioned below the end portions a central portion of the surface forming the convex curved surface, the upper support A first lower support portion disposed so as to face the central portion of the surface of the core member below the first portion, and second and third lower support portions disposed on both sides of the first lower support portion. And a mounting member provided on the upper surface of the first, second, and third lower support portions and on which the skin material is mounted, the upper support portion, and the first lower support portion. Any one of the above is moved so as to approach the other, and the central portion of the mounting member is moved to the central portion of the core surface A first moving means for pressing contact through the skin material, the second, the third lower support part is moved upward, the skin material on both sides of both side portions of the upper placing member surface of said core member And a second moving means for pressing contact with the center member, wherein the first moving means presses and contacts the center portion of the mounting member to the center portion of the surface of the core member via the skin material. 2 When the moving means presses both sides of the mounting member on both sides of the surface of the core material through the skin material, each part of the skin material is applied to the surface of the core material with a uniform pressing force. as imposed, it is characterized in that the mounting member has a predetermined thickness in the vertical direction, and has a predetermined flexibility.
In this case, the above-described second and each side facing the side portions of the third lower support part the core material, are tilted respectively opposite sides with same angle of the core material each side faces Is desirable.
Moreover, it is desirable that both end portions of the second and third lower support portions are connected to each other.

  In the case where the skin material is bonded to the core material by the bonding apparatus of the present invention having the above-described characteristic configuration, the core material is attached to the upper support portion, and is placed in a state where the skin is spread on the placement member. Thereafter, the upper support portion and the first lower support portion are moved closer together by the first moving means, and the second and third lower support portions are moved upward by the second moving means. The upper support portion and the first lower support portion are further stopped by moving closer to a predetermined distance after the center portion of the skin material contacts the center portion of the surface of the core material. In this state, since the central portion of the mounting member is compressed and deformed in the thickness direction, the central portion of the skin material is brought into press contact with the central portion of the surface of the core member by the central portion of the mounting member. The second and third lower support portions are moved further upward after the upper support portion and the first lower support portion are stopped. Then, since the center part of the mounting member is in contact with the center part of the surface of the core member via the skin material, both side parts of the mounting member are elastically deformed along both side parts of the surface of the core material. Accordingly, both side portions of the skin material are brought into press contact with both side portions of the core material. Thereafter, the second and third lower support portions are moved upward and stopped until both side portions of the mounting member are in press contact with both side portions of the core member via the skin material. In this state, the first to third lower support portions press and contact the skin material to the surface of the core material via the mounting member. At this time, the mounting member is not only elastically deformed along the surface of the core material but also elastically deformed in the thickness direction. Accordingly, the display material is pressed against the entire surface of the core material with a substantially uniform pressing force. Therefore, the skin material can be bonded in a substantially uniform state over the entire surface of the core material.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 and 2 show a schematic configuration of an embodiment of a skin material bonding apparatus for vehicle interior parts according to the present invention. The bonding apparatus of this embodiment is for bonding and fixing the skin material T2 to the surface T1a forming the convex curved surface of the core material T1 of the pillar trim (vehicle interior product) T shown in FIGS. Of course, the present invention can also be applied to an apparatus for bonding a core material and a skin material of an interior product other than the pillar trim T.

  The bonding apparatus has a frame (not shown) that is a main body of the apparatus. The frame includes a first upper support portion (upper support portion) 1, a second upper support portion (upper support portion) 2, a third upper support portion (upper support portion) 3, and a fourth upper support portion (upper support portion). ) 4 is provided.

  The first and second upper support portions 1 and 2 are for supporting the core material T1, and the lower surfaces of the support portions 1 and 2 correspond to the back surface T1b forming the concave curved surface shape of the core material T1. It is formed in a convex curved surface. Then, the back surface T1b of the core material T1 is fitted to the lower surfaces forming the convex curved surfaces of the first and second support portions 1 and 2, so that the core material T1 faces the surface T1a forming the convex curved surface downward. In this state, the first and second support portions 1 and 2 are detachably supported in a state where the center portion in the width direction of the surface T1a is located below the both side portions. The 1st, 2nd support parts 1 and 2 are spaced apart and arranged in the longitudinal direction of core material T1. This corresponds to the fact that the back surface T1b of the core material T1 does not have a uniform cross-sectional shape, for example, a convex portion is formed in a part of the longitudinal direction of the core material T1. In order to avoid this, the first and second support portions 1 and 2 are arranged apart from each other in the longitudinal direction of the core material T1. When the convex portion is not formed on the back surface T1b of the core material T1, or when the first and second support portions 1 and 2 are formed in a shape that can avoid the convex portion, 1 and the 2nd support parts 1 and 2 may be formed in one.

  The third and fourth upper support portions 3 and 4 are detachably fitted to the back surfaces of both end portions in the longitudinal direction of the core material T1 supported by the first and second upper support portions 1 and 2. Therefore, the lower surfaces of the third and fourth upper support portions 3 and 4 have shapes corresponding to both end portions of the back surface T1b of the core material T1. However, the third and fourth upper support portions 3 and 4 are not only separated from the first and second upper support portions 1 and 2 in the longitudinal direction of the core material T1, but are also disposed apart upward. Yes. Therefore, when the core material T1 is fitted to the first and second upper support portions 1 and 2, both end portions of the core material T1 are not fitted to the third and fourth upper support portions 3 and 4. . The third and fourth upper support portions 3, 4 are fixed to the tip portions of the rods 5 a, 6 a of the cylinder mechanisms 5, 6 and can be moved in the vertical direction by the cylinder mechanisms 5, 6. Then, when the skin material T2 is bonded to the core material T1, the third and fourth upper support portions 3 and 4 are moved downward and are fitted to both ends of the core material T1, respectively. This is because it is relatively difficult to manually fit the core material T1 to the first and second upper support parts 1 and 2 and at the same time to fit the third and fourth upper support parts 3 and 4. This is due to the fact that If there is no such difficulty, the third and fourth upper support portions 3 and 4 may be formed integrally with the first and second upper support portions 1 and 2, respectively. Therefore, when the 1st, 2nd upper side support parts 1 and 2 are integrally formed, the 1st-4th upper side support parts 1-4 whole will be formed integrally. The third and fourth upper support portions 3 and 4 are not necessarily required.

  Below the first to fourth upper support portions 1 to 4 are a plate-like lower support portion (first lower support portion) 7 and a frame-like lower support portion (second and third lower support portions) 8. Is arranged. The plate-like lower support portion 7 has a rectangular flat plate shape and is disposed in parallel with the first and second upper support portions 1 and 2. The length of the plate-like lower support portion 7 is set slightly longer than the length of the core material T1. Both end portions of the plate-like lower support portion 7 are arranged so as to protrude from both end portions of the core material T1 attached to the first and second upper support portions 1 and 2 in the longitudinal direction of the core material T1. . The width of the plate-like lower support portion 7 is set to 1/3 to 1/2 of the width of the core material T1. The center part in the width direction of the plate-like lower support part 7 is positioned directly below the center part in the width direction of the core member T1.

  The frame-like lower support portion 8 is formed in a rectangular frame shape, and is arranged so as to surround the plate-like lower support portion 7 with a gap around the entire circumference. The upper surface of the frame-like lower support portion 8 is positioned on the same plane as the upper surface of the plate-like lower support portion 7 when the bonding apparatus is in the initial state (when it is in the state shown in FIG. 1). . The upper surface of the frame-like lower support portion 8 may be disposed slightly above the upper surface of the plate-like lower support portion 7. One side portion (second lower support portion) 81 in the width direction of the frame-like lower support portion 8 is arranged to be located slightly outside the one side portion in the width direction of the core member T1. Therefore, when the frame-like lower support portion 8 is moved from the initial position shown in FIG. 3 to the pressing position shown in FIG. 5, the inner side surface of the one side portion 81 faces the side portion of the core material T1. An inclined surface 81 a extending from the upper end to the vicinity of the lower end is formed on the inner side surface of the one side portion 81. The inclination angle of the inclined surface 81a is set to be substantially the same as the inclination angle of the side surface of the core member T1 facing the central portion in the vertical direction of the inclined surface 81a. The other side portion (third lower support portion) 82 in the width direction of the frame-like lower support member 8 is formed symmetrically with respect to a line segment that bisects the frame-like lower support portion 8 in the width direction. Therefore, an inclined surface 82 a is also formed on the inner surface of the other side portion 82. The other side part 82 is formed symmetrically with the one side part 81 because the one side part and the other side part of the core material T1 are formed symmetrically. Accordingly, when the one side portion and the other side portion of the core material T1 are asymmetric, the one side portion 81 and the other side portion 82 are formed corresponding to the one side portion and the other side portion of the core material T1. As a result, the two become asymmetric.

  The frame of the bonding apparatus is provided with cylinder mechanisms 9 and 10 whose axis is directed in the vertical direction. A plate-like lower support portion 7 and a frame-like lower support portion 8 are attached to the upper ends of the rods 9a, 10a of the cylinder mechanisms 9, 10, respectively. Therefore, when the rod 9a moves back and forth in the vertical direction, the plate-like lower support portion 7 is moved in the vertical direction between the initial position shown in FIG. 3 and the pressing position shown in FIGS. As the frame 10a moves forward and backward in the vertical direction, the frame-like lower support portion 8 is moved in the vertical direction between the initial position shown in FIG. 3 and the pressing position shown in FIG.

  A placement member 11 is provided on the upper surfaces of the plate-like lower support portion 7 and the frame-like lower support portion 8. The mounting member 11 is made of a resin foam and is formed in a flat plate shape. The mounting member 11 has an appropriate thickness, flexibility, and strength. This point will be described later. The length of the mounting member 11 is set to be shorter than the distance between the opposing surfaces at both ends in the longitudinal direction of the frame-like lower support portion 8. Both end portions of the mounting member 11 are disposed slightly inward from both end portions of the frame-like lower support portion 8. However, the length of the mounting member 11 is longer than the length of the core material T1. The width of the mounting member 11 is wider than the width of the frame-like lower support portion 8. Therefore, it is wider than the width of the skin material T2. Both side portions of the mounting member 11 in the width direction slightly protrude outward from the frame-like lower support portion 8. The central portion of the mounting member 11 is fixed to the upper surface of the plate-like lower support portion 7. Both side portions of the mounting member 11 are mounted on the upper surface of the frame-like lower support portion 8 so as to be relatively movable. Both side portions of the mounting member 11 may be fixed to the upper surface of the frame-like lower support portion 8.

  Next, a case where the skin material T2 is bonded to the surface T1a of the core material T1 of the door trim T shown in FIGS. 6 and 7 using the bonding apparatus having the above configuration will be described. When bonding the skin material T2 to the core material T1, first, the bonding apparatus is set to the initial state shown in FIG. In the initial state, the third and fourth upper support portions 3 and 4 are positioned at an initial position spaced apart from the first and second upper support portions 1 and 2 by a predetermined distance, and the plate-like lower support The part 7 and the frame-like lower support part 8 are located at an initial position separated downward by a predetermined distance from the first and second upper support parts 1 and 2.

  As shown in FIG. 3, the core material T <b> 1 is attached to the first and second upper support portions 1 and 2 located at the initial position. An adhesive is applied in advance to the surface TIa facing downward of the core material T1. The adhesive may be applied to the surface T1a after the core material T1 is attached to the support portions 1 and 2. On the other hand, on the upper surface of the mounting member 11, the skin material T2 is mounted at a predetermined position.

  When the preparation is completed in this way, the third and fourth upper support portions 3 and 4 are moved downward by the cylinder mechanisms 5 and 6. The plate-like lower support portion 7 and the frame-like lower support portion 8 are moved upward at the same speed by the cylinder mechanisms 9 and 10. Therefore, the mounting member 11 is translated upward in a horizontal state. When the third and fourth upper support portions 3 and 4 are fitted to the back surface T1a of the core material T1, the plate-like lower support portion 7 is substantially simultaneously with the surface of the core material T1 via the mounting member 11 and the skin material T2. Contact the center of T1a. If the 3rd, 4th upper side support parts 3 and 4 move until it fits in back surface T1a of core material T1, it will be stopped.

  On the other hand, the lower support members 7 and 8 are moved further upward by a predetermined distance even after the skin material T2 contacts the core material T1. The lower support member 7 is stopped when it moves further upward to a predetermined position (pressing position) shown in FIG. At this time, the central portion of the mounting member 11 is compressed and deformed by a predetermined amount. That is, the skin material T2 is compressed and deformed by an amount corresponding to the distance moved to the pressing position after contacting the core material T1. As a result, the center portion of the skin material T2 is pressed against the center portion of the core material T2 by the mounting member 11 with a predetermined pressing force.

  The frame-like lower support portion 8 is moved further upward after the plate-like lower support member 7 is stopped. When the lower support portion 8 moves upward, both side portions 81 and 82 lift both side portions of the mounting member 11. As a result, the mounting member 11 is deformed so as to bend along the surface T1a of the core material T1, and accordingly, the skin material T2 is sequentially formed on the surface T1a of the core material T1 from the center side to the both side sides. Contact. Since the skin material T2 sequentially contacts the core material T1 from the center side toward the both side portions, it is possible to prevent wrinkles on the skin material T2. In particular, when both side portions of the mounting member 11 are fixed to both side portions 81 and 82 of the frame-like lower support portion 8, both side portions of the placement portion 11 are moved along with the upward movement of the lower support portion 8. Is pulled upward and deformed, and accordingly, the skin material T2 is pulled upward. Therefore, it is possible to more reliably prevent wrinkles from approaching the skin material T2.

  The frame-like lower support portion 8 is stopped when it moves to a predetermined position (pressing position) shown in FIG. In this state, the skin material T2 is pressed against the entire surface T1a of the core material T1 by the lower support members 7 and 8 via the mounting member 11. At this time, since the mounting member 11 is elastically deformable in the thickness direction (the pressing direction of each part of the skin material T2 against the core material T1), each part of the skin material T2 is pressed against the surface T1a with a substantially uniform pressing force. It is done. In particular, in this embodiment, the inclined surfaces 81a, 82a of the both side portions 81, 82 of the frame-like lower support portion 8 are set to be substantially the same as the inclination angle of the surface T1a at the location facing the surface T1a of the core material T1. Therefore, the skin material T2 can be pressed against the surface T1a with a more uniform pressing force. Since each part of the skin material T2 is pressed against the surface T1a of the core material T1 with a substantially uniform pressing force, the skin material T2 is bonded substantially uniformly to the entire surface T1a.

  When the bonding is completed, the lower support portion 8 is moved downward. When the lower support part 8 reaches the same plane as the lower support part 7, the lower support part 7 is moved downward together with the lower support part 8. Simultaneously with the start of downward movement of the lower support portion 8, the third and fourth upper support portions 3 and 4 are moved upward. Then, the lower support parts 7 and 8 and the third and fourth upper support parts 3 and 4 are stopped when they reach the initial positions. Thereafter, the core material T1 to which the skin material T2 is bonded is removed from the first and second upper support portions 1 and 2, and the bonding operation is completed.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above embodiment, the one side portion 81 and the other side portion 82 of the frame-like lower support portion 8 are used as the second and third lower support portions, respectively. That is, the second and third lower support portions are integrally formed. However, the second and third lower support portions may be formed separately from each other. In that case, it is desirable to move the second and third support portions up and down by separate cylinder mechanisms.
In the above embodiment, the first and second upper support portions 1 and 2 are fixed in position, and the plate-like lower support portion 7 that is the first lower support portion is moved in the vertical direction. The plate-like lower support part 7 may be fixed in position, and the first and second upper support parts 1 and 2 may be moved in the vertical direction.
