JPH115622A - Aligning device for waste vessel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To again align unaligned waste vessels into a line when the unaligned vessels are supposedly conveyed, by sending them into a circulating return passage so as to be returned to the upstream side of the conveyor. SOLUTION: When the input quantity of waste vessels P exceeds the dealing quantity of an aligning device, unaligned waste vessels P1 are further superposed on the waste vessel P correctly housed in the groove 4. Since the height of an inclined guide place 3 is lowered as it goes to the downstream, when the unaligned waste vessel P1 is conveyed downstream, it moves in the direction of the arrow Z1 and rolls down into a circulating return passage 7a. Even when the unaligned waste vessel P1 is stopped in the conveying passage 2a, an aligning plate 6 is abutted on the unaligned waste vessel P1 and forcedly falls it down into the circulating return passage 7a. Since the inclination of the circulating return passage 7a arranged along the conveyor 2 is high on the downstream side and low on the upstream side, the unaligned waste vessel P1 fallen into the circulating return passage 7a slides down onto the upstream side by its own weight.
