MEDICINE STIRRING APPARATUS AND MEDICINE STIRRING METHOD
A stirring apparatus includes a container support section supporting a medicine container, a rotational driving section rotating the medicine container supported by the container support section around a central axis of the medicine container, a vibration driving section reciprocal vibrating the medicine container supported by the container support section along the central axis of the medicine container, pressing rollers arranged opposed to the container support section, the pressing rollers pressing the medicine container across the medicine container between the pressing rollers and the container support section, and a control part controlling the rotational driving section and the vibration driving section. The pressing rollers are diagonally arranged.
1 . A medicine stirring apparatus comprising:
a container support section supporting a medicine container;
a rotational driving section rotating the medicine container supported by the container support section around a central axis of the medicine container via the container support section;
a vibration driving section reciprocal vibrating the medicine container supported by the container support section along the central axis of the medicine container via the container support section;
a pressing roller arranged opposed to the container support section, the pressing roller pressing the medicine container across the medicine container between the pressing roller and the container support section; and
a control part independently controlling driving of the rotational driving section and the vibration driving section, wherein
the pressing roller is diagonally arranged with respect to the central axis of the medicine container supported by the container support section.
2 . The medicine stirring apparatus according to claim 1 , wherein
a rotary axis of the pressing roller is diagonal with respect to the central axis of the medicine container supported by the container support section, and the pressing roller is diagonally arranged closer to a bottom of the medicine container in a rotational direction of the medicine container.
3 . The medicine stirring apparatus according to claim 1 , wherein
at least two pressing rollers are arranged for the medicine container supported by the container support section.
4 . The medicine stirring apparatus according to claim 1 , wherein
the pressing roller is biased by a biasing member toward the container support section.
5 . The medicine stirring apparatus according to claim 1 , wherein
the container support section includes a columnar driving roller and a cylindrical driven roller, and
a central axis of the driving roller is arranged parallel to a central axis of the driven roller.
6 . The medicine stirring apparatus according to claim 1 , wherein
the container support section includes a cylindrical driving roller and a conical driven roller, and
the driven roller is shaped like a conical shape having an outer diameter that becomes smaller toward a bottom of the medicine container supported by the container support section.
7 . The medicine stirring apparatus according to claim 1 , wherein
the rotating mechanism is coupled to the vibrating mechanism with a pair of coupling plates, and
the coupling plate arranged on a lid side of the medicine container supported by the container support section has a concave part for providing a gap between the coupling plate and a lid of the medicine container.
8 . The medicine stirring apparatus according to claim 1 , wherein
the rotating mechanism is coupled to the vibrating mechanism with a pair of coupling plates, and
the coupling plate arranged on a bottom side of the medicine container supported by the container support section has a rotational roller.
9 . The medicine stirring apparatus according to claim 8 , wherein
a rotary axis of the rotational roller is orthogonal to a rotary axis of the driven roller constituting the container support section.
10 . The medicine stirring apparatus according to claim 1 , wherein
the container support section is comprised such that the central axis of the medicine container supported by the container support section horizontally extends.
11 . The medicine stirring apparatus according to claim 1 , further comprising an illumination unit irradiating the medicine container supported by the container support section with light.
12 . A medicine stirring method comprising:
rotating a medicine container around a central axis of the medicine container with a rotational driving section via a container support section under control of a control part with the medicine container sandwiched between the container support section and a diagonally-arranged pressing roller; and
reciprocatingly vibrating the medicine container along the central axis with a vibration driving section via the container support section.
