It is an object of the present invention to provide a transfer device capable of performing the above-described steps.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, a transport apparatus according to the present invention is basically provided with a conveyor for transporting articles such as cereals in a substantially horizontal direction, and a transport apparatus for transporting the articles by the conveyor. The transported object is directly connected to an elevator that transports the transported object to a predetermined height position, and the transported object is directly discharged from the transport end of the conveyor into the elevator. In the transport device of the present invention, preferably, a belt conveyor having an endless annular belt is used as the conveyor, and a bucket elevator in which buckets are attached to the endless annular belt or the endless annular belt at predetermined intervals is used as the elevator.

[0011] More preferably, the conveyed object is discharged directly from a conveying end of the belt conveyor toward a bucket or a bottom storage place of the bucket elevator. In this case, the positional relationship between the conveyor and the elevator is
The conveyed object discharged from the conveyor is set so as to directly fall into a bottom storage place or a bucket of the elevator. In other words, the conveyed object released from the conveyor falls in a parabolic shape with a flight distance corresponding to the conveyor conveyance speed (the belt circulating movement speed). And the bucket should be located.

Therefore, in the transfer apparatus of the present invention, by setting the transfer speed of the conveyor or the elevator to, for example, an optimum speed obtained by an experiment, the object to be transferred is moved from the transfer end of the conveyor to the bucket or the bottom depot of the elevator. It is then dropped down in a desired parabola, and can be conveyed upwards with little or no stacking, either directly into the bucket or scooped up at the bottom depot. By doing so, there is no need to provide a hopper on the elevator side as in the conventional case, so that a pedestal for placing a pit or a conveyor for placing the lower part of the elevator is unnecessary, and as a result, the construction cost of the device is reduced. And the construction period can be shortened, and maintenance, inspection, cleaning, and the like can be performed easily.
