PURPOSE: To improve the probability of alignment, by making parts drop to a transfer conveyor from the up-grade storage conveyor installed in a storage hopper as well as feeding an aligning conveyor consisting of plural conveyors with these parts.

CONSTITUTION: Parts at a lower part in a hopper 11 are conveyed by the up- grade storage conveyor 12 installed in the bottom of the storage hopper 11, and these parts are dropped in a transfer conveyor 25 at the tailing end part 13. These parts are conveyoed upward by the transfer conveyor 25, and dropped in a starting end 19 of an aligning conveyor 18 consisting of plural belts 181 and 182. With these belts 18a and 182, these parts are going toward a tailing end 20 after being arranged by an aligning wall 21. Overflown parts are dropped on a chuting wall 22 and recovered inside the storage hopper 11. With this constitution, the probability of alignment is improved, and a drop in stopping rate is realized, thus automatic feed is made ever so easy.
