ABSTRACT:
When the articles dropping from above are received inside a hopper, at least a bottom portion of the hopper is allowed to move downwardly with the bottom portion of the hopper being closed. Therefore, the collision speed between the articles and the bottom portion of the hopper is reduced. In addition, by opening the bottom portion of the hopper while moving the bottom portion downwardly, the downward initial speed is added to the articles to be discharged.
