DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on preferred embodiments shown in the drawings. FIG. 1 shows a storage box and an air mat used in the method for holding a sheet material for molding a fiber-reinforced resin of the present invention.

In FIG. 1, a storage box 1 is for storing SMC as a sheet material for forming a fiber-reinforced resin to be folded in a stacked state, and the side walls 1a to 1d and the bottom plate 1e are formed of a wire mesh. ing. Therefore, the entire storage box 1 forms a basket structure. In the following description, 1
a is called a front wall, 1b is called a left wall, 1c is called a right wall, and 1d is called a back wall.

Air mats 10 and 11 shown in FIG. 2 are arranged along the opposing inner side walls in the storage box 1. The air mats 10 and 11 can be made of any air-tight bags that do not dissolve in the monomer, have strength to withstand pressure, and are air-tight. A bag formed by laminating a film is shown. Air mat 10
Is formed in a rectangular plate shape and has a thickness t of 50 mm. It is provided in four places in the direction.

At the top of the air mats 10 and 11, quick couplers 12a and 12b are provided, which are connected with an air supply path for supplying air supplied from the compressor 13 and having a flow rate adjusted by a manual valve 14 with one touch. Or you can disconnect.

A method for holding the sheet materials stacked and stored in the above configuration will be described. First, a pair of air mats 10 and 11 before filling with air, that is, in a flat state, are attached to the inner side walls 1 b and 1 facing at least one direction of the storage box 1.
c, and one of the air mats 10 is fixed by hooking a hook 15 provided on the upper part of the air mat 10 to the upper edge of the left side wall 1b, and the hook 16 is fixed to the right side wall 1c. The other air mat 11 is fixed by being hooked on the upper edge.

In this state, the SMCs sent in the direction of arrow C as shown in FIG. 1 are sequentially stacked in the storage box 1 by folding. When the SMC is laminated to a predetermined amount,
The SMC is cut by a cutter (not shown), and the end is stored.

Next, as shown in FIG. 2, an air supply path from the compressor 12 and the air mat 10 are connected via a coupler 12a, and pressurized air is introduced into the air mat 10 to bring the air mat 10 into a predetermined position. Inflate to the shape of When the air filling into the air mat 10 is completed, the coupler 12
a is cut off, and then the air mat 11 is filled with air via the coupler 12b and expanded into a predetermined shape. As a result, both side surfaces of the stacked and stored SMCs come into contact with the inner side wall of the storage box 1 via the air mats 10 and 11, and the SMC is held in the storage box 1. Note that the compressor 13 and the air supply path can be regarded as air supply means.

FIG. 3 shows a method of filling a gap by using a mechanical mechanism instead of the air mat described above. The widening mechanism 20 shown in FIG.
1 and 22 are parallel links 23 and 24 and parallel link 2
5 and 26 are connected to a rod-shaped intermediate member 27. By moving the intermediate member 27 up and down,
The interval between 1 and 22 can be enlarged or reduced. However, the plate member 21 is assumed to be fixed to the left side wall 1b. A cushion member 28 is adhered to a wall surface of the plate member 22 on the SMC side. Also in the configuration shown in the figure, the side surface of the SMC can be brought into contact with the inner side wall of the storage box 1 via the widening mechanism.

In the embodiment shown in FIG.
At the time of taking out, close contact with the SMC is released by removing air from the air mats 10 and 11. If the hooks 15 and 16 are removed, the air mat 1
0, 11 can be removed. In the embodiment shown in FIG. 3, the width of the widening mechanism 20 can be removed by reducing the distance between the plate members 21 and 22.

The above-mentioned widening mechanism is not limited to the widening mechanism using the above-mentioned link mechanism, but may be any one that can expand and contract within the gap between the sheet material side surface and the inner wall of the storage box and can hold the SMC. For example, an arbitrary mechanical mechanism such as a mechanism configured to interlock a plurality of blades arranged in multiple stages and swing from a vertical direction to a horizontal direction can be used.

The air mat or the widening mechanism may be arranged along at least one pair of opposed inner side walls of the storage box, but may be arranged on all opposed inner side walls of the storage box.

In the present invention, the sheet material for molding a fiber-reinforced resin is described using SMC in the above embodiment. However, the present invention is not limited to this, and can be applied to BMC (Bulk Molding Compound) and the like.
