Description

This disclosure relates to a surface shape adjustment device and a method for manufacturing interior components using this surface shape adjustment device. Conventional examples of using far-infrared devices as drying equipment are known (see, for example, Patent Document 1). Special Publication No. 2008-502872 Front view of a skin shape adjusting device according to an embodiment of the present disclosure.A top view of a skin shape adjustment device according to an embodiment of the present disclosure.A figure showing a method for manufacturing an interior component using a surface shape adjustment device according to an embodiment of the present disclosure. An embodiment of this disclosure will be described below with reference to the figures. In the specification and drawings, the right side of the skin shape adjustment device 1, as viewed from the front, will be referred to as "right," the left side as "left," the upper side as "up," and the lower side as "down." Furthermore, the front side (lower side in Figure 2), as viewed from the front, will be referred to as "front," and the rear side (upper side in Figure 2) as "rear." As shown in Figures 1 and 2, the surface shape adjustment device 1 comprises a support base 2, an irradiation device 4, an injection device 6, an adjustment mechanism 8, and a control device 10. In this embodiment, the surface shape adjustment device 1 for adjusting the surface resin sheet 12 used for an automobile instrument panel (an example of an interior component) to match the design surface shape of the instrument panel base material 14 will be described as an example. The support base 2 supports the base material 14 of the interior component, and the resin sheet 12, which forms the surface of the interior component, is placed on top of the design surface 14a of the base material 14. In this embodiment, the support base 2 is a plate-shaped member on which the base material 14 of the instrument panel is positioned so that the design surface 14a is the upper surface. The base material 14 is supported by a support bracket 2a attached to the support base 2. The resin sheet 12 is placed on top of the design surface 14a facing upwards of the base material 14. The support base 2 is equipped with wheels 2c at the lower ends of each of its four legs 2b and is positioned to be movable at least in the front-to-back direction. After the resin sheet 12 is placed on it, the support base 2 moves toward the rear of the irradiation device 4 and is positioned beneath the irradiation device 4. The irradiation device 4 is a device that irradiates far-infrared rays toward the resin sheet 12 from the side where the resin sheet 12 is placed. When the resin sheet 12 is irradiated with far-infrared rays, the resin sheet 12 is instantly heated, drying and removing the moisture from the resin sheet 12. This induces shrinkage due to the decrease in the moisture content of the resin sheet 12. Multiple irradiation devices 4 are arranged along the design surface 14a. In this embodiment, five are arranged side by side in the left-right direction, with one additional device placed at the front right. Each irradiation device 4 is supported by a gate-shaped frame 4a. In the surface shape adjustment device 1 of this embodiment, the devices are arranged along the shape of the resin sheet 12 so that far-infrared rays can be irradiated onto the entire resin sheet 12. This allows for even irradiation of the resin sheet 12 with far-infrared rays. Furthermore, each irradiation device 4 is detachable from the frame 4a. Therefore, for example, if there are parts of the resin sheet 12 that do not require far-infrared irradiation, the irradiation device 4 at the corresponding position can be removed. More specifically, as shown in Figure 2, the meter hood resin sheet 12a at the position corresponding to the meter hood portion 14b of the instrument panel base material 14 does not require far-infrared irradiation. In this case, among the multiple irradiation devices 4, the irradiation device 4b corresponding to the meter hood portion 14b is removed. This prevents the meter hood resin sheet 12a from being irradiated with far-infrared rays and thus prevents drying. Alternatively, the operation of each of the multiple irradiation devices 4 may be controlled separately by the control device 10. This allows, for example, that only the irradiation device 4b corresponding to the meter hood portion 14b is not activated, or its far-infrared output is weakened. As a result, only the meter hood resin sheet 12a portion can be left undried, or the degree of drying can be reduced. In any case, by arranging multiple irradiation devices 4 along the design surface 14a, each irradiation device 4 can be removed, or its operation can be adjusted. This allows for drying (or not drying) only specific areas of the resin sheet 12, or adjusting the degree of drying for each part of the resin sheet 12. Note that in the above embodiment, the meter h
