In the second characteristic configuration, the sand falling along the sliding surface of the guide plate hits the roof tile surface in a direction different from the falling direction, so that the same result as the first characteristic configuration is obtained. In the third characteristic configuration, the scattered sand does not fall only in the vertical direction, but is thrown from the side in a parabola, so that it can be applied to the tile surface with a wide angle range, and therefore it can be leveled. The sand can be attached to the surface of the roof tile along various directions from the vertical direction to the vertical direction, and can also be attached to the uneven surface of a complicated shape. In the fourth characteristic configuration, since the sand riding on the wind from the sand falling direction changing unit can be applied to the tile surface in various directions depending on the strength of the wind, it is the same as the first characteristic configuration. The result of is obtained. By appropriately increasing the strength of the wind, the speed and direction of hitting the sand tile can be adjusted, which is effective in the case where the sand must be strongly collided with the tile in order to adhere. In the fifth characteristic configuration, since the sand can be attached to the surfaces in various directions by changing the direction of the tile surface without changing the falling direction of the sand, the conventional sand spreader is used. The sand can be attached to the vertical surface of the roof tile, and can also be attached to the uneven surface of a complicated shape. In the sixth characteristic configuration, since the sand can be simultaneously attached to the surface in any direction, it is effective when the sand is to be attached to the roof tile having a complicated shape.

[Other Embodiments] <1> The sand sprinkling device used in the above embodiments is provided with a rotating sand sprinkling body, but the construction of the sand sprinkling device is not limited to these, and sand is not limited to this. Any material can be dropped and supplied, and sand can be sprinkled directly from the hopper. Also,
A sensor is installed in the transport device to control and start the sand spraying device.
The configuration for stopping may be omitted. <2> In the first embodiment, the sand reflectors may be slidably mounted in the direction of the rotation axis of the sand sprinkler, and the sand reflectors are moved by the moving mechanism according to the shape of the roof tile. It may be one. Further, the position and the attitude of the reflector may be drive-controlled to control the position and the attitude according to the shape of the roof tile to be conveyed. <3> In the second embodiment, the sand guide device may have a drive unit and a sand supply unit slidably attached to each other in the direction of the rotation axis of the sand spraying body. It may be moved according to the shape. The position and orientation of the guide plate may be drive-controlled to control the position and orientation according to the shape of the roof tile being conveyed. <4> In the third embodiment, as shown in FIG. 4, the rear wall of the sand scraping device 6 has a curved surface drawn from a position lower than the rear wall of FIG. 3, and the cover 6e is inflated rearward.
And a part of the guide surface 6f is covered with a sand scraping piece 6a.
Is formed in a shape substantially conforming to the rotating outer peripheral cylindrical surface, and the radius of the cylindrical surface is slightly smaller than the radius of the rotating outer peripheral cylindrical surface to form a resistance sliding surface 6g, and the rear wall of the sand pool 12a and the guide surface. It may be formed into a smooth shape continuous to 6f. Here, the sand hanging means is closer to the rear wall than the position shown in FIG. 3, and when the sand hanging means is driven to rotate in the direction of arrow R by a driving device (not shown), the sand scraping piece 6a is moved. Is provided at a position slightly closer than the position in contact with the rear wall. With this configuration,
Since the support plate 6b is formed of a flat plate-like elastic body having a width in the axial direction of the attached rotary shaft 6c, the sand scraping piece 6a enters the sand of the sand pool 12a. When it is touched and when it is in the sand of the sand puddle 12a, it is elastically bent by the resistance of the sand, and when it contacts the rear wall, it is elastically bent by the sliding resistance between it and the resistance sliding surface 6g. , Causes rotation delay. Thus, when the sand scraping piece 6a holds the sand 12b scooped from the sand pool 12a while the supporting plate 6b is bent, and the sand scraping piece 6a is separated from the resistance sliding surface 6g. , The sand 1 is accelerated in the rotational direction R by the reaction force of the bending of the support plate 6b.
2b is strongly thrown away (then, the supporting plate 6b vibrates and then returns to its original state). In this way, since the sand grains 12 are accelerated and sprinkled, the sand grains 12 reach the roof tile 11 sufficiently even if the rotation speed of the sand hanging means is slowed.
It is possible to reduce the fluctuating load on the driving device (not shown) when the rotation speed is increased. Furthermore, since the initial velocity at the time of spreading the sand grains 12 can be increased, the tracks of the sand grains 12 can be brought close to horizontal, and the sand grains 12 can be more easily attached to the standing surface 11c of the roof tile 11. Further, instead of the structure in which the sand scraping piece rotating around the horizontal axis scatters the sand, another method may be used to scrape the sand and scatter the sand. Further, the sand scraping piece may be held on a circular support. Further, the shape thereof may be a long U-shaped section or a U-shaped section, and the shape thereof may be a bowl shape, and further, a plurality of these are arranged side by side. It may be. The sand scraping device may be rotated in the opposite direction (of course, the direction in which the sand scraping piece is attached in this case is also reversed), and the sand may be thrown up.
Further, the cover may be extended further forward to reflect the thrown sand toward the roof tile. <5> In the fourth embodiment, the nozzle 7a shown in FIG.

The track A of the sand grains 12 can be freely changed by adjusting the direction and strength of each of the _two . Further, the sand falling direction changing means may be slidably mounted in the direction of the rotation axis of the sand sprinkling body, and further, this is moved by the moving mechanism according to the shape of the roof tile. Good.
Further, the position and posture of the nozzle and the air pressure blown out from the nozzle may be controlled according to the shape of the roof tile to be conveyed. <6> In the fifth embodiment, the means for evenly distributing the sand in the axial direction, which is provided inside the sand sprinkling body, can be omitted. Further, the sand sprinkling device automatically supplies the sand. The supply unit does not have to supply automatically, and may have a configuration in which sand is preliminarily charged in the sand spray body. Furthermore, the swing control unit may be omitted, and instead of the swing control unit, a posture control unit that controls only the posture of the nozzle without fixing the nozzle may be provided. It may be realized as a drive control unit. In addition, the air pressure may be variable and may be controlled according to the shape of the roof tile to be conveyed, or may be controlled in conjunction with this and the drive control unit, the swing control unit, the attitude control unit, and the like. <7> In the sixth embodiment, the first sand spraying device may be omitted and the sand may be attached only at the other two places. The tile support may be maintained in a flat position by gravity, and instead of swinging the tile support, two vertically movable supports are used and vertically driven by an attitude changing mechanism. However, the roof tile may be tilted to change the posture of the roof tile, or, in addition, a roof tile pedestal having a mechanism different from that capable of tilting to change the posture of the roof tile may be provided. Also,
It is also possible to attach an attitude changing mechanism to the tile support and operate the attitude changing mechanism at a predetermined position. <8> In the seventh embodiment, regardless of the method for floating the sand, a floating device is provided which can float the sand in the sand floating space and allow the roof tile to enter and leave the sand floating space. The roof tile may be allowed to enter the sand floating space, and the roof tile may be withdrawn after the sand is attached. <9> In addition, the configuration of the present invention is not limited to the configuration of the above embodiment, and may be any configuration based on the characteristic configuration of the present invention.
