Medicine feeding device and a medicine counting device using the medicine feeding device

摘要

A medicine feeding device is configured by providing a first rotor that rotates around a first shaft, a second rotor that rotates around a second shaft, a partition wall extending from the second rotor towards the first rotor, a medicine discharge port provided on the outside of the second rotor, a medicine guide section located in the downstream of a movement section in the medicine transport direction, and a height regulator disposed between the movement section and medicine guide section. In addition, the width regulator that is disposed between the medicine guide section and the height regulator is further provided. Also, a medicine counting device is further provided with a medicine detection means for detecting the medicine that is supplied from the medicine discharge port, and a counting means (central control unit) for counting the medicines based on the detection performed by the medicine detection means.

1. A medicine counting device provided with a medicine feeding device, the 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, andan 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; and 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 the medicine counting device comprising: a medicine detector for detecting a medicine that is discharged from the medicine discharging port; a counting means for counting number of medicines supplied based on a detection by the medicine detector; and a switching valve unit comprising a medicine passage that is divided into a first passage and a second passage arranged adjacent to each other, wherein the switching valve is able to switch a discharge destination of a medicine, which is discharged from the medicine guiding section, to either the first passage or the second passage, said switching valve further comprising: a first swing member for opening and closing the first passage; and a second swing member for opening and closing the second passage, wherein each swing member is provided with an elastic part that is elastically deformable.
