  • Patent number: 6041963
    Abstract: An ampule collector which can collect selected ampules from corresponding feeders without breakage and jamming of ampules. The ampule collector has a plurality of cylindrically stacked ampule feeders in which are stored different kinds of ampules. In order that ampules, discharged from selected feeders drop only a short distance, a vertically movable ampule collecting container is provided in the center of the cylindrical structure defined by the feeders. Jamming of ampules is prevented by rotating a bottom cover provided at the center of the ampule collecting container, stirring ampules with protrusions formed on the conical inner surface, and changing the directions of the ampules with vanes provided on the conical inner surface. With the container inserted in an ampule stocker provided under the bottom cover, it is possible to supply ampules into the stocker without breaking them.
