As shown in (II), the coating process of the adhesive 16 is performed, and the base material 12 is placed in a state where the uneven pattern transfer surface 14 faces upward.
Is placed horizontally on a conveyor 106 (see FIG. 6).

When the base material 12 conveyed along the horizontally extending conveyance path of the conveyor 106 passes below the spraying device 28, the base material 12 is transferred onto the uneven pattern transfer surface 14 as shown in (III). The coloring decorative material 18 is sprayed to form a layer of the coloring decorative material 18.

Here, the spraying treatment of the colored decorative material 18 is performed as follows.
The operation of the spraying device 28 will be described in more detail with reference to FIGS. When spraying the colored cosmetic material 18, the spraying device 28 is driven by a motor 82 so that
6 and the diffusion plate 40 are rotated. And screw 30
a, the colored cosmetic material 1 inside the hopper 20
8 is sent downward and is continuously supplied from the one end opening 34 to the center of the upper surface of the discharge plate 36.

After passing through the substrate 44, it is dispersed in a divergent conical shape with respect to the uneven pattern transfer surface 14 of the substrate 12 supported substantially horizontally.

At this time, in the colored decorative material 18 which has been vigorously released from the release board 36, the decorative material having a heavy specific gravity and the light decorative material are evenly dispersed. This is because the decorative material having a high specific gravity has a diffusion plate 40
Is passed through the through-hole 46 without hitting, and is emitted far away with the released momentum. However, since the remaining decorative material hits the diffusion plate 40 and flows below the diffusion plate 40, it is scattered. This is because, together with the decorating material having a light specific gravity and not flying far away, the material is evenly spread in a divergent conical shape with respect to the base material 12.

Further, the spraying of the colored decorative material 18 is performed by disposing the spraying device 28 including the rotating discharge plate 36 and the diffusion plate 40, which is directly or indirectly supported by the columns 56, along the running rail 58. 12 while moving in the direction perpendicular to the transport direction. Thereby, the colored decorative material 1 can be more effectively applied to the side surface of the uneven portion on the uneven pattern transfer surface 14.

In the spraying process, the amount of the colored cosmetic material 18 to be sprayed is regulated by moving the brush 50 up and down to a predetermined position of the cylindrical portion 26.

That is, in the present embodiment, the brush 50 and the discharge disk 36 are actuated by the action of the screw portion 30a due to the pushing force of the colored cosmetic material 18 and the operation of the ridge 38 (see FIG. 3) of the rotating discharge disk 36. The coloring decorative material 18 is released from a gap formed between the coloring material 18 and the surface. Therefore, by moving the brush 50 up and down to adjust the contact force between the brush 50 and the discharge board 36, the amount of the colored cosmetic material 18 to be sprayed can be adjusted.

Further, in this manufacturing apparatus, the weight of the hopper 20 and the members integral with the hopper 20 are constantly measured during the spraying of the coloring cosmetic material 18. When the measurement result of the weight becomes a predetermined lower limit, it is determined that the amount of the coloring cosmetic material 18 in the hopper 20 has decreased, and the coloring cosmetic material 18 is supplied to the hopper 20 from the tank 96 through the feeder 98 and the feeder 98. It is supplied through the guide tube 104.

As described above, the colored decorative material 18 is moved up and down by the moving means in the vertical direction with respect to the base material 12 conveyed by the conveyor 106 according to the program of the moving means, The release plate 36 and the diffusion plate 4 are moved by the moving means in a direction perpendicular to the direction
0 is dispersing vigorously while moving 0, and the uneven pattern transfer surface 1
After forming the layer of the coloring decorative material 18 on 4, the side plate 116 is set, the concrete material 114 is poured, and after the concrete material 114 is solidified, it is released from the mold. As a result, a concrete molded body having the uneven pattern transferred to the surface and colored and decorated with the colored decorative material 18 is obtained.

According to the manufacturing method of this embodiment, the colored decorative material 18 continuously supplied to the upper surface of the discharge plate 36 is vigorously discharged obliquely downward by the centrifugal force generated by the rotation of the discharge plate 36, and this is diffused by the diffusion plate 40. Are dispersed by passing through the through-holes 46 of the base material 12 and sprinkled on the uneven pattern transfer surface 14 of the base material 12 to form a layer of the colored decorative material 18. The colored decorative material 18 can be satisfactorily sprinkled on the side surface of the uneven portion, and therefore, a uniform layer of the colored decorative material 18 can be formed on the uneven pattern transfer surface 14.

Also, due to the action of the diffusion plate 40, even the colored decorative material 18 in which a decorative material having a high specific gravity and a light decorative material are mixed is evenly distributed on the uneven pattern transfer surface 14 of the base material 12. Can be sprinkled.

According to the present embodiment, the work of spraying the colored cosmetic material 18 can be performed mechanically and automatically, and the conventional manual work can be omitted. Therefore, it is possible to solve the problem that dust scattered in the air harms workers, and also solve the problem that a difference in product quality occurs between an expert and a beginner.

In this embodiment, the hopper 20 is supported in a vertically movable manner by a vertical moving means, and the weight of the hopper 20 and the spraying device 28 integrated therewith are measured by the weight sensor 78. According to the present example, it is possible to spray the colored cosmetic 18 while constantly monitoring the remaining amount of the colored cosmetic 18 inside the hopper 20 based on the measurement result by the weight sensor 78. Therefore, it is possible to prevent the spraying process from being performed mechanically in a state where the colored cosmetic material 18 inside the hopper 20 is empty.
