BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a lining substrate according to an embodiment of the present invention;
This is applied to manufacture a door lining for a vehicle by bonding the cloth material 3 as a center pad to a predetermined portion of the skin material 1 while adhering to the plate surface. Figure 1
2 shows a device for manufacturing a car interior member having a partial distribution, which has a different configuration. The device includes a lining substrate 2 which is provided with clamps 10a and 10b such as clamps for expanding and flattening the skin material 1 and supporting it. The main difference is that the vacuum bonding die 20 for assembling and the receiving die 30 for assembling the fabric material 3 are mounted upside down.

As the skin material 1, polyvinyl chloride resin (PVC), olefin-based thermoplastic elastomer (TP)
O) or the like can be used. The skin material 1 is formed as a laminated material by laminating a cushion pad of foamed polypropylene, foamed polyvinyl chloride, or the like on the back layer of a synthetic resin sheet as a surface layer.

As the lining substrate 2, an injection molded plate of a polypropylene resin or the like or a press molded plate of a wooden base material can be used. Of these, the press-formed board made of a wood base material has air permeability in terms of material, so that vacuum evacuation bonding of the skin material 1 can be applied as it is. In the case of the injection molded plate, it is formed so as to have a predetermined three-dimensional shape, and is formed so that a plurality of ventilation holes 2a are scattered on the plate surface as shown in FIG. On the plate surface of the lining substrate 2, a wood groove 2 b is provided so as to form a portion corresponding to the bonding surface of the fabric material 3.

The fabric material 3 can be used by cutting a moquette, tricot, double Russell, jersey or the like into a predetermined contour shape in accordance with a desired planar shape of the center pad.

As the adhesive (not shown), a thermoplastic adhesive is used. The thermoplastic adhesive includes a hot-melt type such as polyolefin, synthetic rubber, vinyl acetate resin, polyamide, and polyurethane, and a polyurethane, chloroprene rubber, and vinyl acetate resin. And styrene-butadiene solvents. In particular, a hot-melt adhesive may be used for the fabric material 3. Further, it is preferable to use a moisture-reaction curing type, since the cloth material 3 can be firmly bonded to the skin material 1.

In the apparatus for manufacturing a car interior member with partial distribution shown in FIG. 1, the vacuum bonding mold 20 for assembling the lining board 2 is attached to the lower side and the fabric material 3 is attached via the positions of the supports 10a and 10b. A receiving mold 30 is provided on the upper side. In the arrangement of the equipment, since the vacuum bonding die 20 and the receiving die 30 are operated in the same process and are mounted vertically, it is possible to reduce the installation space in the factory as well as the personnel.

Further, a relatively heavy vacuum bonding type 20 is used.
By equipping the lower side with the receiving mold 30 having a relatively low weight, the whole apparatus can be operated stably. These components include support devices 10a and 10b such as clamps for flatly expanding the skin material 1 for tensile support, and the vacuum bonding mold 20 and the receiving mold 30 can use existing facilities.

The vacuum bonding type 20 is provided with a convex portion 21 on which the lining substrate 2 is mounted and mounted on a plate surface of a lower fixing plate 22. Also, this vacuum bonding type 20 is
2 is equipped so as to be able to move up and down by a predetermined stroke. The convex portion 21 is provided with a plurality of suction holes 23 communicating from the inside of the mold to the mold surface, and an air suction mechanism through which the vacuum pressure can be applied to the skin material 1 via the lining substrate 2. (Not shown) is connected.
In addition, a concave portion 24 is provided on the mold surface of the convex portion 21 so as to fit the groove 2b on the back surface side of the lining substrate 2.

The receiving mold 30 is formed of the convex part 21 of the vacuum bonding mold 20.
The mold surface is partially similar to the above, and the mold surface is downwardly attached to the upper fixed plate 31 via a spring 32 so that the mold surface can be displaced. This receiving mold 30 is also a vacuum bonding mold 2
Like 0, it is equipped to be able to move up and down with a predetermined stroke.

The receiving die 30 is for sucking and supporting the fabric material 3 under the die surface under vacuum pressure. The receiving die 30 is provided with a plurality of intake holes 33 communicating from inside the die to the die surface. An air suction mechanism (not shown) is connected. In the suction holes 33, when a moisture-reaction curing type adhesive is used for bonding the fabric material 3, a steam delivery mechanism (not shown) for heating and melting the adhesive and promoting the reaction is provided with an air suction mechanism. Switchable and connectable.

In addition to the above-described respective mechanical parts, a wood grain bar 4
0 is the receiving mold 4 so that it can protrude downward from the mold side of the receiving mold 30.
0 is provided on the upper plate 31. The wood grain bar 4
The lower end 0 has a shape similar to the plane shape of the wood-groove groove 2b provided on the plate surface of the lining board 2, and the receiving cylinder 30 is displaced by the spring 32 to resiliently deviate, or the drive cylinder and the like are connected to the wood-groove bar 40. The lower end side can be protruded toward the wood-groove groove 2b of the lining substrate 2 by operating in preparation for.

In addition, as the vacuum bonding die 20 and the receiving die 30 move closer to each other, the guide posts 41a, 41b, 4
2a and 42b are planted on the plate surfaces of the upper and lower fixed plates 22 and 31, respectively.

In the apparatus for manufacturing a car interior member having a partial distribution as described above, the skin material 1 is sandwiched between the supporting members 10a and 10b such as clamps with the adhesive applied side facing downward. It is flattened and supported above the vacuum bonding mold 20. The lining substrate 2 is a vacuum bonding type 2
It is mounted on the 0-shaped convex portion 21. The fabric material 3 is suction-held on the mold surface of the receiving mold 30 with a vacuum pressure with the adhesive application side facing downward. In this state, the skin material 1 is subjected to a heat treatment for reactivating the adhesive, and the vacuum bonding mold 20 and the receiving mold 30 are moved toward the skin material 1 held by tension with the supports 10a and 10b.

When the mold surface reaches the skin material 1 with the upward movement of the vacuum bonding mold 20, the skin material 1 is heated and softened and is flattened and supported, so that the skin material 1 is wrinkled or twisted. Can be easily covered on the plate surface of the lining substrate 2 so as not to cause the occurrence. Further, as the mold surface of the vacuum bonding die 20 comes into pressure contact with the skin material 1, the support members 10 a and 10 b move in a direction close to each other, so that the skin material 1 is approximately matched with the three-dimensional shape of the lining substrate 2. Can be covered. Thereafter, in the vacuum bonding die 20, if a vacuum pressure is applied to the skin material 1 from the mold surface via the lining substrate 2, the skin material 1 can be vacuum-bonded to the plate surface of the lining substrate 2.

On the other hand, the receiving die 30 is moved down toward the skin material 1 covering the plate surface of the lining substrate 2 in synchronization with the vacuum bonding die 20. When the receiving mold 30 reaches the skin material 1,
The skin material 1 is evacuated to the plate surface of the lining substrate 2 and is in a state substantially corresponding to the three-dimensional surface of the lining substrate 2, and the fabric material 3 is pressed and pressed against a predetermined portion of the skin material 1 on the mold surface of the receiving mold 30. You.

With the pressing and pressing of the fabric material 3, the heating temperature at the time of reactivating the adhesive of the skin material 1 is transmitted to the thermoplastic adhesive applied to the back surface of the fabric material 3. This makes it possible to heat and melt the adhesive. For this reason, the skin material 1 applied to reactivate the adhesive of the skin material 1
By using the heating temperature of the fabric material 3, the fabric material 3
In addition, the adhesive can be securely fixed.

When a moisture-reaction curing type adhesive is used as the adhesive, the air suction mechanism of the receiving mold 30 is switched to a steam sending mechanism so that the steam acts on the fabric material 3 from the mold surface of the receiving mold 30. If this is the case, the adhesive can be more reliably heated and melted and the reaction can be promoted. For this reason, the cloth material 3 can be quickly and reliably bonded to the skin material 1.

With the adhesion of the skin material 1 and the fabric material 3, the wood grain bar 40 moves together with the edge of the fabric material 3.
While being pressed against the in-plane portion of the lining board 2, it is fitted into the groove of the wood groove 2 b. When the skin material 1 and the fabric material 3 are completely bonded, the edge of the fabric material 3 and the in-plane portion of the skin material 1 are also completely pressed into the wood-groove groove 2b by the wood-groove bar 40, and the cloth material 3 The in-plane portion of the skin material 1 together with the edge can be fitted and bonded in the groove of the wood grain groove 2b. For this reason, the edge of the fabric material 3 and the in-plane portion of the skin material 1 can be beautifully grained and bonded without individually graining.

After the bonding, the support 10 of the skin 1
a, 10b are detached from the skin material 1, and the vacuum bonding type 2
When the dies 0 and the receiving mold 30 are returned to their original positions, the lining substrate 2 to which the skin material 1 and the fabric material 3 are bonded is returned to the original position while being attached to the convex surface of the vacuum bonding die 20. I can do it. By removing the lining substrate 2 from the vacuum bonding mold 20, it can be commercialized as a door lining.

Although the above embodiment has been described with reference to the case where a door lining for a vehicle is manufactured, the present invention is similarly applied to the manufacture of a vehicle interior member such as a body side lining, a seat back cover, and a rear tray. Can be.

A receiving mold 30 is provided on the lower side. The receiving mold 30 is provided with only a steam delivery mechanism, and
A set pin 43 of the cloth material 3 is provided on the side of the receiving mold 30 for positioning.

Further, in order to regulate the falling dead center of the vacuum bonding die 20, a butting post 44 is provided standing up from the base plate of the receiving die 30. The abutment post 44 is supported by a spring or an air cylinder or the like so as to be able to be deflected so as to reduce the contact with the vacuum bonding die 20. Other than that, it is configured to have the same structure as the manufacturing apparatus of the partially distributed vehicle interior member shown in FIG.

In the apparatus for manufacturing a car interior member with partial distribution, the skin material 1 is developed in a flat shape by clamping the peripheral edge of the skin material with supporting members 10a and 10b such as clamps with the adhesive application side facing upward. Then, it is supported above the receiving mold 30. The lining substrate 2 is mounted downward on the convex portion 21 of the vacuum bonding die 20. The cloth material 3 is set on the mold surface of the receiving mold 30 with the adhesive application side facing upward.
Assemble by positioning and holding in step 3.

In this state, the adhesive of the skin material is heat-treated in the same manner as described above, and the vacuum bonding die 20 and the receiving die 30 are moved toward the skin material 1 which is pulled and held by the supports 10a and 10b. Thereby, the bonding process of the skin material 1 and the cloth material 3 can be performed together in the bonding process of the skin material 1.
