Description

[Technical Field]

[0001] The present disclosure relates to a method for manufacturing a luggage board. [Background technology]

[0002] 2. Description of the Related Art Luggage boards as described below have been well known as components that form the floor of a luggage room of an automobile. That is, the luggage room is located, for example, behind the rear seats inside the interior of a car, and the luggage board is provided, for example, as a lid that closes the luggage compartment under the floor from above, and the luggage compartment can be opened by pulling up the luggage board.

[0003] Furthermore, from the viewpoints of rigidity, light weight, and appearance, the luggage board has the following layer structure: A core material for raising the luggage board is placed between two resin plates, and a skin material is placed on the outer surface of at least one of the resin plates. The luggage board is then assembled so that the skin material is exposed inside the luggage compartment.

[0004] Furthermore, from the viewpoint of productivity, recent manufacturing methods for luggage boards have increasingly included a press process for press-molding the material. Therefore, in the press process, due to the need to form the layer structure described above, the material is arranged as follows between two dies and then pressurized. That is, a core material is sandwiched between two resin plates that have been softened in advance by heating, and a skin material is placed on the outer surface of at least one of the resin plates. The materials thus arranged are then sandwiched between two molds and pressurized to form the material.

[0005] For example, in Patent Document 1, of two resin plates, one resin plate is vacuum-sucked into a lower mold to shape the lower surface of the first resin plate, a core material is placed on this resin plate, and then a second resin plate is placed on the core material.Then, vacuum-sucking is also applied to the upper mold to shape the upper surface of the second resin plate, and the molds are closed to apply pressure to the material present between the upper and lower molds.

[0006] Incidentally, in Patent Document 1, pressure is applied to the skin material while it is interposed between the upper mold and the second resin plate, but it is not clear how the skin material is interposed between the upper mold and the second resin plate. However, unlike other materials, skin materials are extremely flexible and have little tension. For this reason, for example, if you simply place the skin material on a second resin plate and clamp it under vacuum, the finished product will likely have many wrinkles.

[0007] [Patent Document 1] Patent No. 5603534 Summary of the Invention [Problem to be solved by the invention]

[0008] Therefore, an object of the present disclosure is to suppress the occurrence of wrinkles in a skin material in a manufacturing method for a luggage board that utilizes press molding of a material. [Means for solving the problem]

[0009] The luggage board manufactured by the manufacturing method of the present disclosure is to be assembled in the luggage room of an automobile, and has a core material for raising the height placed between two resin plates, and a skin material placed on the outer surface of at least one of the resin plates. The manufacturing method of the luggage board of the present disclosure also includes the following preheating and pressing steps. First, in the preheating step, two resin plates are heated and softened. Next, in the pressing step, a main material part with a core material disposed between the two softened resin plates is press-molded.

[0010] In the pressing process, the main material portion is sandwiched and pressed between one mold for shaping the outer surface of one of the two resin plates and the other mold for shaping the outer surface of the other resin plate. In the pressing process, the skin material is placed under tension between the outer surface of one resin plate and the shaping surface of the one mold, and between the outer surface of the other resin plate and the shaping surface of the other mold. In the pressing process, the skin material is pressed together with the main material portion while being kept under tension. As a result, the manufacturing method for a luggage board according to the present disclosure can potentially suppress the occurrence of wrinkles in the skin material even when press molding of the material is used.

[0012] The embodiments of the present disclosure will be described in more detail in the following examples. [Example]

[0013] [Configuration of Example 1] The configuration of the luggage board 1 of the first embodiment will be described. First, the luggage board 1 is a component that forms the floor of the luggage room 3 of the automobile 2, and is provided, for example, as a lid that closes the luggage compartment 4 under the floor from above, and is configured so that the luggage compartment 4 can be opened by pulling up the luggage board 1 (see FIG. 1). The luggage room 3 is, for example, located behind the rear seats 5 inside the automobile 2.

[0014] Furthermore, the luggage board 1 has the following layer structure: In other words, in the luggage board 1, a core material 10 and a reinforcing material 11 are disposed between two resin plates 9, and a skin material 12 is disposed on one of the two surfaces of one of the resin plates 9, on the surface opposite to the side on which the core material 10 and the reinforcing material 11 are located (see FIG. 2; hereinafter, the surface of the resin plate 9 opposite to the side on which the core material 10 and the reinforcing material 11 are located may be referred to as the outer surface).

[0015] The core material 10 is used to raise the height of the luggage board 1, and the reinforcing material 11 is used to increase the rigidity of the luggage board 1. The skin material 12 is used to improve the appearance, and the luggage board 1 is assembled so that the skin material 12 is exposed inside the luggage room 3.

[0016] Here, the two resin plates 9 are, for example, filler-reinforced resin molded products made by blending filler with polypropylene, and have the same composition and thickness. Various fillers can be used, such as silica, calcium carbonate, carbon fiber, and glass fiber.

[0017] The core material 10 is a resin foam made of, for example, expanded polypropylene, and the reinforcing material 11 is a metal body having an H-shaped cross section made of, for example, aluminum. The skin material 12 can be, for example, a nonwoven fabric made of fiber or a thin film made of resin. A method for manufacturing the luggage board 1 will now be described.

[0018] [Manufacturing method of Example 1] A manufacturing method of the luggage board 1 of the first embodiment will be described with reference to the drawings. The manufacturing method of the luggage board 1 of the first embodiment includes the following preheating step P1, preparation step P2, pressing step P3, and cooling step P4 (see FIG. 3). First, in the preheating step P1, the two resin plates 9 are heated and softened in a heating furnace that utilizes far infrared rays.

[0019] Next, in the preparation process P2, tension is applied to the skin material 12 by setting the skin material 12 in a predetermined jig 14 (see Figs. 4 and 5, etc.). The jig 14 has a shape that can surround from the outside the two dies 15A and 15B used in the pressing process P3, and applies tension to the skin material 12 while holding it on its inner periphery.

[0020] More specifically, the jig 14 has, for example, the following frame 14A and a plurality of needles 16. That is, the frame 14A is rectangular and annular, and the shape of the inner periphery is designed so that it can surround the dies 15A and 15B from the outside. Furthermore, the needles 16 are assembled, for example, three on each side of the inner periphery of the frame 14A.

[0021] More specifically, three protrusions 14B are provided on the inner periphery of frame body 14A, protruding inward, and one needle 16 is fixed to each of protrusions 14B. The direction in which needles 16 protrude is perpendicular to the plane formed by the ring of frame body 14A. All of protrusions 14B are provided so that dies 15A and 15B can fit inside their own inner periphery ends. Then, the needles 16 are inserted into the vicinity of the periphery of the skin material 12, thereby applying tension to the skin material 12 while the jig 14 holds the skin material 12.

[0022] Next, in the pressing step P3, various materials are sandwiched between dies 15A and 15B and press-molded (see FIGS. 6 and 7). Here, the pressing step P3 is carried out by the following pressing device 18 (see FIG. 8). The pressing device 18 is made up of the above-mentioned dies 15A and 15B, a driving unit 18a, a control unit 18b, and the like.

[0023] First, molds 15A and 15B are the lower and upper molds in press device 18, and mold 15B is assembled so as to face mold 15A in the vertical direction and so as to be able to approach mold 15A from above or move away from it from above. The drive unit 18a drives the mold 15B. Various drive methods can be used, such as air drive and motor drive. The control unit 18b is, for example, a well-known control panel, and outputs various control signals to the drive unit 18a and the like to control the operation of the mold 15B.

[0024] Then, the press device 18 press-moldes the material, for example, as follows: First, the mold 15B is pulled up relative to the mold 15A, and various materials are stacked on the mold 15A, thereby arranging the materials between the molds 15A and 15B. Then, the mold 15B is lowered toward the mold 15A and clamped, thereby pressurizing and press-molding the materials.

[0025] The various materials press-molded in press step P3 are a main material portion 19 in which core material 10 and reinforcing material 11 are disposed between two resin plates 9, and skin material 12. These materials are disposed between molds 15A and 15B, with skin material 12 disposed below main material portion 19. More specifically, the materials are disposed between molds 15A and 15B in the order of skin material 12, one resin plate 9, core material 10 and reinforcing material 11, and the other resin plate 9, from bottom to top.

[0026] Then, in the press process P3, the outer surfaces of the resin plates 9 located on the lower and upper sides are shaped by the shaping surfaces 15As and 15Bs of the molds 15A and 15B, respectively (hereinafter, the resin plates 9 located on the lower and upper sides of the main material part 19 arranged between the molds 15A and 15B may be referred to as resin plates 9A and 9B, respectively).

[0027] Furthermore, in the pressing step P3, the skin material 12 is press-molded together with the main material portion 19 while being kept in a tensioned state. Therefore, in the pressing step P3, the skin material 12 in a tensioned state is placed between the outer surface of the resin plate 9A and the shaping surface 15As. In other words, by placing the jig 14 on the outer periphery of the dies 15A and 15B with the skin material 12 set in place, the skin material 12 faces the shaping surface 15As on the inner periphery side of the jig 14. Hereinafter, the pressing step P3 will be further divided into a plurality of steps and will be described in order.

[0028] The pressing step P3 includes the following first to fourth pretreatment steps P3a to P3d and a pressing step P3e (see FIG. 3). The first to fourth pretreatment steps P3a to P3d are steps in which two resin plates 9, a core material 10, and a reinforcing material 11 are arranged between molds 15A and 15B to form a main material part 19, and a skin material 12 is arranged between main material part 19 and mold 15A.

[0029] First, in the first pre-treatment step P3a, the skin material 12 that has undergone the preparation step P2 is placed on the mold 15A. That is, the skin material 12 is placed on the mold 15A while being held by the jig 14 and kept in a state in which tension is applied (see FIGS. 4, 5, etc.). Here, the protrusion 14B of the jig 14 is provided so that the molds 15A and 15B fit inside the inner circumferential end of the protrusion 14B of the jig 14. Therefore, the skin material 12 is placed, for example, on the upper periphery of the mold 15A, and the entire jig 14 including the protrusion 14B is suspended near the periphery of the skin material 12 outside the mold 15A.

[0030] Next, in the second pretreatment step P3b, one of the resin plates 9 that has been subjected to the preheating step P1 is placed on the skin material 12 placed on the mold 15A. At this time, the one of the resin plates 9 has been softened in the preheating step P1, and the softened resin plate 9 is placed on the skin material 12. Next, in the third pre-treatment step P3c, the core material 10 and the reinforcing material 11 are placed on the resin plate 9 placed on the skin material 12. Then, in the fourth pre-treatment step P3d, the other resin plate 9 that has undergone the pre-heating step P1 is placed on top of the core material 10 and reinforcing material 11 that are placed on one of the resin plates 9. At this time, the other resin plate 9 has also been softened in the pre-heating step P1, and the softened resin plate 9 is placed on the core material 10 and reinforcing material 11.

[0031] As a result of the above, a main material portion 19 is formed between the molds 15A and 15B (see FIG. 6), and the skin material 12 is placed below the main material portion 19 and above the mold 15A. Subsequently, in the pressurizing step P3e, the mold 15B is lowered toward the mold 15A and clamped, thereby pressurizing and press-molding the main material portion 19 and the skin material 12 (see FIG. 7).

[0032] As a result, the outer surface of resin plate 9A is shaped together with skin material 12 by shaping surface 15As, and the outer surface of resin plate 9B is shaped by shaping surface 15Bs. Furthermore, resin plates 9A and 9B are integrated by welding their peripheral edges, and core material 10 and reinforcing material 11 are fixed between resin plates 9A and 9B. Furthermore, skin material 12 is welded to the welding portions of resin plates 9A and 9B and is attached to the outer surface of resin plate 9A.

[0033] At the same time, in the pressurizing step P3e, the welded portions and skin material 12 at the peripheries of the resin plates 9A and 9B are sheared by clamping the mold. Thereafter, mold 15B is lifted from mold 15A, and the material in which skin material 12 and main material portion 19 are integrated is taken out (hereinafter, the material in which skin material 12 and main material portion 19 are integrated may be referred to as intermediate body 20).

[0034] In the pressing step P3, regarding the heat dissipation from the resin plate 9A to the mold 15A and the heat dissipation from the resin plate 9B to the mold 15B, the amount of heat dissipation from the resin plate 9B to the mold 15B is greater than the amount of heat dissipation from the resin plate 9A to the mold 15A. In other words, the amount of heat transferred per unit time from the resin plate 9B to the mold 15B is greater than the amount of heat transferred per unit time from the resin plate 9A to the mold 15A.

[0035] That is, although skin material 12 exists between resin plate 9A and mold 15A, skin material 12 has a large heat transfer resistance. Therefore, the amount of heat dissipated from resin plate 9B to mold 15B is greater than the amount of heat dissipated from resin plate 9A to mold 15A, and therefore, in intermediate body 20 removed from molds 15A and 15B, resin plate 9B has cooled more than resin plate 9A.

[0036] Next, in a cooling step P4, the intermediate body 20 is held in a predetermined jig 22 and cooled (see FIG. 9). The jig 22 holds the intermediate body 20 so that the periphery of the intermediate body 20 is pressed toward one side from the center, and has, for example, a concave body 22A having a recess 22a that is recessed toward the center, and a convex body 22B having a convex portion 22b that protrudes toward the center.

[0037] Here, in the cooling step P4, with respect to the heat dissipation from the resin sheets 9A, 9B to the dies 15A, 15B, respectively, in the pressing step P3, the intermediate 20 is held while the periphery of the intermediate 20 is pressed toward the resin sheet 9B, which dissipates the greater amount of heat. That is, in the cooling step P4, the intermediate 20 is held by the jig 22 so that the skin material 12 and the resin sheet 9A are positioned on the side of the concave portion 22A, and the resin sheet 9B is positioned on the side of the convex portion 22B. In this way, the intermediate 20 is held so that the periphery is pressed toward the resin sheet 9B. That is, the intermediate 20 is held so that the periphery is pressed toward the resin sheet 9B, which was cooled more quickly in the pressing step P3.

[0038] [Effects of Example 1] The luggage board 1 of Example 1 is to be assembled in the luggage room 3 of an automobile 2, and has a core material 10 for raising the height placed between two resin plates 9, and a skin material 12 placed on the outer surface of one of the resin plates 9. The manufacturing method of the luggage board 1 of the first embodiment also includes the following preheating step P1 and pressing step P3.

[0039] That is, in the preheating step P1, the two resin plates 9 are heated and softened. Then, in the pressing step P3, the main material portion 19 is press-molded, with the core material 10 disposed between the two softened resin plates 9. Then, in the pressing step P3, the main material portion 19 is sandwiched and pressed between a mold 15A that shapes the outer surface of one of the resin plates 9 and a mold 15B that shapes the outer surface of the other resin plate 9. Then, in the pressing step P3, the skin material 12 is placed in a tensioned state between the outer surface of one of the resin plates 9 and the shaping surface 15As of the mold 15A, and further, the skin material 12 is pressed together with the main material portion 19 while being kept in a tensioned state.

[0040] This potentially makes it possible to prevent wrinkles from occurring in the skin material 12 even when press molding of the material is used. That is, since the skin material 12 is pressurized together with the main material portion 19 while being kept in a tensioned state, it is possible to prevent wrinkles from occurring in the skin material 12 even when press molding of the material is used.

[0041] The manufacturing method of the luggage board 1 of Example 1 also includes the following preparation step P2. That is, in the preparation step P2, tension is applied to the skin material 12 by setting the skin material 12 in a jig 14. The jig 14 has a shape that can surround the dies 15A and 15B from the outside, and applies tension to the skin material 12 while holding the skin material 12 on its inner periphery.

[0042] In the pressing step P3, the jig 14 is placed on the outer periphery of the dies 15A and 15B with the skin material 12 set therein, so that the skin material 12 faces the shaping surface 15As on the inner periphery side of the jig 14. This makes it possible to easily continue to apply tension to the skin material 12 even during the pressing step P3, thereby further suppressing the occurrence of wrinkles in the skin material 12.

[0043] Furthermore, according to the manufacturing method of the luggage board 1 of Example 1, in the pressing process P3, the mold 15A is positioned below the mold 15B, and the mold 15B is lowered toward the mold 15A to apply pressure to the main material portion 19 and the skin material 12. This allows press molding to be performed with the skin material 12 sandwiched between the mold 15A located on the lower side and the resin plate 9 located on the lower side. This stabilizes the position of the skin material 12, further reducing the occurrence of wrinkles in the skin material 12.

[0044] The manufacturing method of the luggage board 1 of Example 1 also includes the following cooling step P4. That is, in the cooling step P4, the intermediate body 20 including the main material portion 19 and the skin material 12 after press molding is cooled. Also, in the cooling step P4, the intermediate body 20 is held while pressing the periphery of the intermediate body 20 toward the resin plate 9B that dissipates the greater amount of heat in relation to the heat dissipation from the resin plates 9A, 9B to the molds 15A, 15B, respectively, in the pressing step P3. That is, the intermediate body 20 is held so that the periphery is pressed toward the resin plate 9B that cooled faster in the pressing step P3. This can prevent the intermediate body 20 from warping.

[0045] That is, there is a high possibility that the intermediate body 20 removed from the molds 15A and 15B will warp toward the resin plate 9A, which was cooled slowly in the pressing step P3. Therefore, in the cooling step P4, the intermediate body 20 is held so that the peripheral edge of the intermediate body 20 is pressed toward the resin plate 9B. This makes it possible to prevent the intermediate body 20 from warping.

[0046] [Configuration of Example 2] According to the luggage board 1 of the second embodiment, the reinforcing member 11 is a metal body having a rectangular cross section, and is made of aluminum (see FIG. 10).

[0047] [Modification] The present invention can be modified in various ways without departing from the spirit of the invention. For example, according to the manufacturing method of the luggage board 1 of Example 1, in the press step P3, the skin material 12, one resin plate 9, the core material 10 and the reinforcing material 11, and the other resin plate 9 are sequentially placed on the mold 15A, and then the mold 15B is lowered to perform press molding, but the form of press molding is not limited to this form.

[0048] For example, mold 15A may be provided with holes for vacuum suction, and after skin material 12 and one of the resin plates 9 are attached to mold 15A by vacuum suction, core material 10, reinforcing material 11, and the other resin plate 9 may be placed on top of mold 15A in that order. In this case, vacuum suction is applied to the gap between shaping surface 15As and skin material 12, so that the outer surfaces of skin material 12 and resin plate 9A can be shaped more reliably.

[0049] Alternatively, mold 15B may also be provided with a hole for vacuum suction, and the other resin plate 9 may be brought into close contact with mold 15B by vacuum suction, and then mold 15B may be lowered toward mold 15A for press molding. In this case, vacuum suction is applied to the gap between shaping surface 15Bs and the outer surface of resin plate 9B, thereby enabling the outer surface of resin plate 9B to be shaped more reliably.

[0050] Furthermore, one of the molds 15A, 15B may be provided with a hole for injecting pressurized air into the mold, and the pressurized air may be injected into the internal space of the intermediate body 20. In this case, the outer surfaces of the skin material 12 and the resin plate 9A can be more firmly attached to the shaping surface 15As, and the outer surface of the resin plate 9B can be more firmly attached to the shaping surface 15Bs. This allows the outer surfaces of the skin material 12 and the resin plate 9A, as well as the outer surface of the resin plate 9B, to be shaped more reliably.

[0051] Furthermore, according to the manufacturing method of the luggage board 1 of Example 1, the jig 14 holds the covering material 12 with the needles 16 to apply tension, but the form of the jig 14 is not limited to this. For example, clips may be attached to the inner periphery of the frame body 14A instead of the needles 16, and the covering material 12 may be held and tensioned by the clips. Furthermore, means for holding the covering material 12 and applying tension, such as the needles 16 or clips, may be provided integrally with either one of the dies 15A or 15B.

[0052] Furthermore, in the luggage board 1 of Example 1, the skin material 12 is attached only to the outer surface of the resin plate 9A. However, the skin material 12 may be attached to the outer surfaces of both the resin plates 9A and 9B. When the skin material 12 is attached to the outer surfaces of both the resin plates 9A and 9B, the types and bulk densities of the skin materials 12 may be different. In this case, the amount of heat dissipated from the resin plate 9A to the mold 15A differs from the amount of heat dissipated from the resin plate 9B to the mold 15B, and it is highly likely that one of the resin plates 9A and 9B will cool faster. For this reason, in the cooling step P4, it is preferable to hold the intermediate body 20 while pressing the periphery toward the resin plate 9 that dissipated heat faster.

[0053] Furthermore, according to the luggage board 1 of Example 1, both of the two resin plates 9 were resin molded products made of polypropylene mixed with filler, but a thermoplastic resin other than polypropylene may be used as the matrix resin, for example, polyamide, polyester, etc. may be used, or a polyolefin other than polypropylene may be used.

[0054] Furthermore, in the luggage board 1 of Example 1, the core material 10 is a resin foam made of foamed polypropylene, but foamed polystyrene or a composite resin foam of polystyrene and polyolefin may also be used as the material for the core material 10. Also, foams such as polyvinyl chloride, polyurethane, resol-type phenol, melamine-based resin, and epoxy-based resin may also be used.

[0055] Furthermore, according to the luggage board 1 of Example 1, the reinforcing material 11 is a metal body having an H-shaped cross section, and according to the luggage board 1 of Example 2, the reinforcing material 11 is a metal body having a square-shaped cross section, but the reinforcing material 11 may be formed to have a honeycomb structure or may be embossed.
