A screw conveyor is also used as this type of transfer device.

However, in the screw conveyor, since the object to be conveyed moves while being pushed by the screw due to the rotation of the screw, the rotation axis of the screw must be a straight line, so that the screw conveyor has a three-dimensional, for example, three-dimensional curved shape. Transport is difficult.

Further, as this type of transfer device, a pneumatic transfer type conveyor is also used.

However, the pneumatic conveying type conveyor is
Since an object to be conveyed is conveyed by air pressure, it is generally used for conveying an object having a relatively small specific gravity, and it is difficult to convey an object having a relatively large specific gravity.

The transported object moves along the inside of the substantially cylindrical transport body, so that the hermeticity is maintained and the transported object is transported without scattering. Further, by providing a flexible spiral-shaped conveying blade portion on the inner peripheral surface of the conveying body, when the driving body rotationally drives the conveying body in the circumferential direction of the conveying body, the conveyed object is It moves along this carrier blade. As a result, regardless of the specific gravity of the transported object and the positional relationship between the transported object inlet side and the transported object outlet side of the transported body, the transported object moves from the transported object inlet side to the transported object outlet side. Is transported to the side. As a result, the transferred object having a relatively large specific gravity is transferred, and the transferred object is transferred in three dimensions by connecting the plurality of transfer bodies in three-dimensional communication.

Further, the transfer blades 11a, 21a, 31a are the transfer tubes 1
It does not have to be formed integrally with 1, 21, 31 and may be formed of another member having flexibility and fitted to the inner peripheral surface of the transport pipes 11, 21, 31.

Further, the number of the transfer blades 11a, 21a, 31a may be smaller or larger as long as the transferred object 2 can be efficiently transferred.

The carrier tubes 11, 21, 31 may be made of transparent material. In this case, the transport state of the transported object 2 inside the transport pipes 11, 21, 31 can be easily visually confirmed.
