  • Patent number: 8944281
    Abstract: The medicine packing machine is equipped with a loading unit that is capable of receiving and delivering vials retrieved from a stocker, and a supplying unit that is capable of delivering the vials from the loading unit in an upright position. A control unit is also disposed between the loading unit and the supplying unit. As a result of the presence of the control unit, the transfer of vials received by the loading unit is controlled by the control unit in such a manner that the vials are not ejected towards the supplying unit. The vials are also controlled so as to be in an upright position once loaded into the loading unit. As a result of these actions, the vials received by the loading unit are reliably delivered to the supplying unit without being ejected or jamming at unanticipated locations.
