PURPOSE: To reduce an installation area to efficiently use a storage floor area in a conveyor device for bulk material such as coal by providing a conveying belt-guide part having a curved conveying part and an inclined conveying part, a follower-belt operating in cooperation with the conveying belt, and a load carrying-out conveyor on a carriage travelling on rails.

CONSTITUTION: A conveying belt 2 is laid over a drive roller 2a, a tail roller 2b, the top roller 2a of a travelling carriage A, a return roller 2b, the curved part supporting roller 11 of a conveyance guide part 10, etc., to be driven in the direction of the arrow c. Objects to be conveyed by the conveying belt 2 are held between a follower-belt 9 and the conveying belt 2 in the travelling carriage A to be conveyed and discharged to a carrying-out conveyor 14. At this time, the travelling carriage A is moved in the directions of the arrows a, b in a storage yard, and the conveyor 14 is turned in the e-direction to convey the objects to a specified position and store them at the position. By this constitution, saving of space, efficient use of space can be achieved.
