By a News Reporter-Staff News Editor at Journal of Engineering -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Takahama, Makio (Hirakata, JP); Yoshinori, Kenzo (Hirakata, JP), filed on September 17, 2014, was published online on July 3, 2018.
The patent's assignee for patent number 10010485 is Takazono Technology Incorporated (Osaka, JP).
News editors obtained the following quote from the background information supplied by the inventors: "As a medicine feeding unit, a 'medicine feeder' disclosed in Patent Literature 1, for example, can be mentioned. This medicine feeding unit is basically provided with a medicine container that contains solid medicines (which is described as a 'container' in Patent Literature 1, and the terms in the parentheses in the 'Background' are the names of the members according to Patent Literature 1), and a substantially cylindrical rotor that is rotatably located in the medicine container. The medicine container is detachably attached to a support (drive unit). The rotor rotates about the vertical axis. As the rotor rotates, medicines can be sequentially ejected from a medicine outlet provided in the medicine container. The ejected medicines are fed, for example, to a packaging device.
"In the configuration disclosed in Patent Literature 1, when the medicine container is mounted on the support, the fitting member of the medicine container is fitted to the fitting member of the support. This fitting allows a driving force to be transmitted from the support to the medicine container. In the state where the two fitting members cannot be fitted to each other, the end faces of the two fitting members abut each other (in an abutting state). In such an abutting state, the fitting member on the medicine container side rotates due to vibration or the like even if no driving force is transmitted from the support. Then, the rotor rotates and the medicines are ejected from the medicine container when the medicines should not be ejected. This is a problem because the medicines cannot be fed as prescribed."
As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "Technical Problem
"Therefore, it is an object of the present invention to provide a medicine feeding unit capable of suppressing ejection of the medicines from the container when the medicines should not be ejected.
"Solution to Problem
"The present invention is a medicine feeding unit configured to feed solid medicines, the unit including: a medicine feeder having a medicine container configured to contain the medicines and a driven shaft provided rotatably to the medicine container, the medicine feeder being configured to feed the medicines from the medicine container by the driven shaft being rotationally driven; and a support having a rotary drive source and a driving shaft that is connected coaxially with the driven shaft and that is rotationally driven by the rotary drive source, the support being configured to detachably support the medicine feeder, wherein the driven shaft has a driven shaft body and a driven engagement member that is movable in the axial direction relative to the driven shaft body, the driving shaft has a driving shaft body and a driving engagement member that is fixed to the driving shaft body and that is engaged with the driven engagement member, the driven engagement member is biased in an approaching direction approaching the driving engagement member, and the medicine feeding unit further includes a rotation preventing part configured to allow the driven engagement member to rotate in an engaged state in which the driven engagement member is engaged with the driving engagement member, and to prevent the driven engagement member from rotating in an abutting state in which the driven engagement member abuts the driving engagement member without being engaged therewith, in a mounted state in which the medicine feeder is mounted on the support.
"Further, the rotation preventing part can have a movable locking part provided in the driven engagement member, and a fixed locking part that is provided in the medicine container and is arranged to be spaced apart from the movable locking part in the engaged state and to lock the movable locking part in the abutting state.
"Further, the configuration can be such that the medicine container is provided with a recess in which the driven engagement member is located, the movable locking part is provided in an outer circumferential portion of the driven engagement member, and the fixed locking part is provided in an inner circumferential portion of the recess of the medicine container."
