The configuration of the first roller conveyor 28 is the same as that of the first roller conveyor 28 in that the

In the case of the free roller 62 shown in FIG.
The cross-sectional shape is provided to be inclined upward from one side to the other side so as to substantially follow the shape of the back surface near the collar portion E of the rough land N.

Therefore, as shown in FIG. 5, the first conveyor 24 supports the central portion of the back surface of the waste land N for cross tiles, and the first roller conveyor 28 supports the mountain S of the waste land N.
Can be supported by raising the second roller conveyor 30 slightly, so that the shape of the back surface of the waste land N can be maintained even when the waste land N contains moisture. Can be conveyed without impairing.

Although the two types of the free rollers 54 and 62 have been described above, the inventor also plans to make the cross-sectional shape circular or planar. It is needless to say that the versatility of the transfer device can be further expanded by increasing the number of rollers and adding a third roller conveyor.

In the embodiment of the present invention, in addition to the above example, the following contrivances have been made to further improve the transport function, and this point will be described with reference to the drawings.

The extruded product M extruded and extruded from the extruder 10 and the waste land N after cutting correspond to the type and form of the extruded product, and the extruded product transfer device 12
As described above, the first conveyor 24, the second conveyor 26, the first roller conveyor 28, and the second roller conveyor 30 of the transfer device 20 for wasteland and wasteland are used by appropriately combining them. is there.

When the first conveyors 24 are used in combination, the extruded product is conveyed in a state of being deviated to one side or the other side in the direction perpendicular to the conveying direction due to the difference in the combination. Although the center of the product is necessarily biased to one side or the other side, the extruder 10 is usually fixed to the installation surface, and the extruded product is to be biased to one side or the other side. It is difficult.

In order to cope with the state where the center of the extruded product is deviated, the conveying device 1 for the extruded product is used.
It is required to be able to move the center of the transfer device 20 for wasteland or wasteland to one side or the other side in a direction perpendicular to the transfer direction of the extruded product.

A rail 70 is laid under the machine base 22 of the transfer device 20 for wasteland in a direction perpendicular to the conveying direction of the extruded product, and the machine 70 is mounted via wheels 72 provided at a lower portion of the machine base 22. A transfer device 20 for wasteland supported on a table 22 is provided so as to be able to reciprocate in a direction perpendicular to the transfer direction of the extruded product.

Thus, when the first conveyor 24 is used in combination in accordance with the type and form of the extruded product, the center position of the waste land N moves to one side or the other side. The transfer device 20 for wasteland can be moved to one side or the other side in accordance with the movement of the center position of the wasteland N.

Next, a description will be given of a method of using the transfer device 20 for wasteland when the extruded product is wasteland N for eaves tiles or sleeve tiles.

The above-described wasteland N for tile roof is in a state where it is turned upside down (see FIG. 6). In this case, the transfer device 20 for the rough land N is set so that the center of the rough land N and the center of the free rollers 54 of the second roller conveyor 30 substantially coincide with each other.
Has been moved to one side (the left side in the drawing) in the direction perpendicular to the transport direction of.

The collar section E of the wasteland N is on the second belt conveyor 26, the mountain section S is on the first conveyor 24, and the height of the second roller conveyor is adjusted by operating the elevation control mechanism 60. The center of the rough land N rising in a curved shape is supported by 30 free rollers 54.

Thus, the transfer of the waste land N for the roof tile such as the eaves tile is carried out in a stable posture without tilting, so that the deformation which occurs during the transfer does not occur.

The example shown in FIG. 7 is an example in which the waste land N has a half-cut cylindrical portion D and a curved portion R, and is used for an S-type clay tile or a main roof tile.

In this case, the transfer device 20 for wasteland is so arranged that the center of the wasteland N and the center of the first conveyor 24 substantially coincide with each other.
Has been moved to the other side (the right side in the drawing) in a direction perpendicular to the transport direction of the wasteland N.

Then, the outer end of the half-cut cylindrical portion D of the wasteland N is on the second conveyor 26, the raised back surface of the half-cut cylindrical portion D is on the free roller 54 of the second roller conveyor 30, and The curved portion R near the half-cylindrical portion D is the first conveyor 24.
And the vicinity of the end of the curved portion R is the first roller conveyor 2.
8 are supported by free rollers 62.

In this case, since the half cylindrical portion D of the waste land N is relatively high curved, the free roller 54 of the second roller conveyor 30 is raised and lowered to support the back surface of the half cylindrical portion D. By operating the control mechanism 60, it is raised slightly higher.

Furthermore, since the vicinity of the end of the curved portion R has a relatively small inclination, when it is necessary to follow the inclined surface, it is replaced with a free roller 62 having a small inclined surface.

As described above, the transfer of the waste land N for the S-type clay tile or the roof tile is performed in a stable posture without tilting, so that the deformation or bending which is likely to occur during the transfer does not occur.

The terrain N has a symmetrical shape in which a gentle curve is drawn in a circular arc, and is an example for a roof tile or a ridge roof tile (see FIG. 8).

In this case, the transfer device 20 for the wasteland is so arranged that the center of the wasteland N and the center of the first conveyor 24 substantially coincide with each other.
Has been moved to the other side (the right side in the drawing) in a direction perpendicular to the transport direction of the wasteland N.

The center of the waste land N is located on the first conveyor 24, and the vicinity of both ends of the waste land N is located on the first roller conveyor 28.
The back surface is supported by the free roller 62 of the second roller conveyor 30 and the free roller 62 of the second roller conveyor 30, respectively.

In this case, the free rollers 62 of the first roller conveyor 28 and the second roller conveyor 30 are located on a wasteland N
Free roller 6 with a small inclined surface corresponding to the shape of the rear surface of
2, 62 have been replaced.
