Patent ID: 8827112

Claim:
A medicine feeding device, comprising: a first rotor that is configured to rotate around a first axis; a second rotor in annular shape that is configured to rotate around a second axis extending in a direction different from that of the first axis; a partition wall extending from an inner circumference of the second rotor toward an outer circumference of the first rotor, wherein a medicine fed to the first rotor is transferred by rotation of the first rotor to a transfer part of the second rotor, and transferred medicine is transported to a downstream side in a rotating direction by rotation of the second rotor; a medicine discharging port provided outside in a radial direction of the second rotor; a medicine guiding section that is configured to guide a medicine on the second rotor to the medicine discharging port, the medicine guiding section comprising: an inner guide provided in downstream in a medicine transport direction of the transfer part of the second rotor and extending from an inner circumference of the second rotor towards the medicine discharging port, and an outer guide positioned outer side in a radial direction of the second rotor with respect to an inner guide and having a gap that is roughly same as a width of a medicine; a height regulator provided between the transfer part of the second rotor and the medicine discharging port and positioned so as to have a gap that is roughly same as a height of a medicine from an upper surface of the second rotor, and a width regulator provided between the medicine guiding section of the second rotor and the height regulator, and disposed outside in a radial direction of the second rotor from an inner circumference of the second rotor with a predetermined gap, and is configured to regulate a transport width of a medicine in a space between an inner circumference of this second rotor and the width regulator, wherein a transport width of the second rotor is adjustable by the width regulator, wherein the width regulator and an outer guide of the medicine guiding section are integrally provided for allowing a transport width of the second rotor and a space between each of guides of the medicine guiding section to be simultaneously adjustable, and wherein: a regulated height between the height regulator and the second rotor is adjustable, a first medicine detector to detect a medicine passing through the height regulator and a second medicine detector to detect a medicine passing through the medicine guiding section are provided, and the medicine feeding device has a configuration that the height regulator is gradually raised; the height regulator is stopped when a passage of a medicine is detected by the first medicine detector; an outer guide of the medicine guiding section and the width regulator are gradually moved in a radially outward direction of the second rotor; and an outer guide of the medicine guiding section and the width regulator are stopped when a passage of a medicine is detected by the second medicine detector.
