ARTICLE ACCUMULATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an article accumulation device which reduces vibration and noise generated by the collision of articles at the time of fall when the articles are dropped and accumulated.SOLUTION: An article accumulation device 1 accumulates articles W falling into an accumulation container 30 which has an opening 31 at the top. The article accumulation device 1 has a fall cushioning part 10. The fall cushioning part 10 comprises: a plate-like collision part 11 provided in the middle of a trajectory t on which the articles fall into the accumulation container 30; a fall part spring member made of a spring which expands and contracts in a gravity direction; and a support part 12 provided below the collision part 11 for supporting the collision part 11 through the fall part spring member. The fall cushioning part 11 comprises a fall part power generator having a coil and a magnetic body for generating electric power by electromagnetic induction by moving relatively in the gravity direction. One of the coil and the magnetic body of the fall part power generator is connected to the fall part spring member and preferable to move relatively with respect to the other following the telescopic motion of the fall part spring member.
