[Prior art]
2. Description of the Related Art Conventionally, the following are generally present as drug storage containers such as tablets incorporated in a drug selection and supply device.
[0003]
That is, as shown in FIG. 5, a taper that inclines with a downward slope from the center toward the outer periphery on the upper surface of a circular roller 43 that rotates in one direction on the bottom plate 42 of the medicine container 41 of the medicine 40 such as a tablet. The surface 44 is provided, and the upper part of the circular roller 43 is formed in a conical shape. By rotating the circular roller 43 having the tapered surface 44, the stored medicine 40 such as a tablet is agitated and slides on the tapered surface 44, and the discharge guide path 45 provided on the outer periphery of the circular roller 43 is provided. In this configuration, a predetermined amount is discharged (indicated by an arrow) in the direction of the arrow in the figure (see, for example, Patent Document 1).
There is also a medicine container in which the tapered surface is inclined from one end side to the other end side of the outer periphery (see, for example, Patent Document 2).
[0004]
However, in the conventional drug container 41, when the drug 40 is charged, that is, when a large amount of drug 40 is stored in the drug container 41, the drug 40 is circular along the tapered surface 44. It accumulates on the upper outer peripheral side 46 of the roller 43, and bridging (a naturally occurring mass of the drug) occurs due to the weight and shape of the drug 40.
On the other hand, since the circular roller 43 is integrally formed as a single member even when the circular roller 43 rotates, it is not easy to break the bridging that has occurred once, and the medicine 40 enters the discharge guide path 45. There was a problem that it could not be introduced.

A drug stirring roller body 3 is provided at a substantially central portion in the drug container main body 1, and the medicine stirring container body 1 faces downward from one wall surface 4 of the drug container main body 1 and the other wall surface 5 facing it. The bottom portion 6 is integrally extended with an inclination to form a medicine storage portion 7.
[0011]
The drug agitating roller body 3 is loosely fitted to a shaft 11 that is erected on a support body 10 in a gear storage portion 9 provided via a partition plate 8 below the drug container main body 1. A cylindrical body 12 and a substantially circular core body 15 in a plan view formed by being screwed and fixed to a male screw portion 14 formed on the upper end 13 side of the shaft core 11 are formed. With this configuration, the drug stirring roller body 3 is provided substantially vertically with respect to the drug container support 2 on which the drug container body 1 is mounted, and rotates with its vertical axis, that is, the axis 11 as a rotation axis. It is.
[0012]
More specifically regarding the drug stirring roller body 3, a cutout portion 16 having a substantially circular shape in a plan view and a substantially concave shape in a sectional view is formed on the circular upper surface side of the cylindrical body 12 so that the core body 15 can be fitted therein. A substantially cylindrical cutout portion 18 is formed on the lower surface side so as to be fitted into a cylindrical support portion 17 protruding upward from the partition plate 8 of the medicine container main body 1. The hole 19 is penetrated. Further, the cylindrical body 12 is centered on the axial core 11 by the outer fitting of the hole 19 of the cylindrical body 12 to the insertion tube 20 that is loosely fitted to the axial core 11 and is loosely fitted to the support portion 17. It is rotatably supported with respect to the medicine container support 2. Note that the lower portion of the insertion tube 20 protrudes into the gear housing portion 9, and a large gear 21 is fixed to the distal end side thereof.
[0013]
Further, as shown in FIG. 3, on the outer peripheral side of the cylindrical body 12, ellipsoidal capsule medicines 22 are inserted and ten discharge guide paths 23 are formed at equal intervals so as to be vertically arranged. The upper side surfaces 23a of the discharge guide path 23 are tapered so that the medicine 22 can easily enter the discharge guide path 23 as shown in FIG.
[0014]
On the other hand, the upper surface portion of the core body 15 is formed as an inclined portion 24 having a high portion 15a having a high peripheral end and a low portion 15b having a low other peripheral end by cutting a substantially cylindrical shape obliquely. The upper end 13 of the shaft core 11 is fixed to the notch 16 of the cylindrical body 12 so as to be positioned on the medicine container 7 side. A small gear 26 is fixed to the lower end 25 side of the shaft core 11 protruding from the gear housing 9.
[0015]
A drive transmission shaft 27 is pivotally supported on the support body 10 in the gear housing portion 9 in the same direction as the shaft core 11, and a large gear 21 fixed to the insertion tube 20 of the cylindrical body 12 on the upper side thereof. And a small gear 26 fixed to the shaft core 11 are fixedly attached to a small gear 26, and a rotary drive device for a drug container support 2 in a drug selection and supply device mounted on the lower side thereof. A connection 31 is provided to connect to 30.
[0016]
Reference numeral 32 denotes a medicine supply port opened in the partition plate 8 of the medicine container main body 1, and the medicine supply port 32 has a medicine flow passage to communicate with a medicine discharge port 33 provided in the medicine container support 2. 34 is provided.
[0017]
Reference numeral 35 denotes a locking body having a locking portion 35a having a substantially L-shaped cross-sectional view, which is detachably fixed to one wall surface 4 of the medicine container main body 1. The distance between the locking portion 35a and the partition plate 8 is as follows. A locking portion 35a is fitted into an opening 36 formed in the one wall surface 4 so as to be substantially the same length as the drug 22, and is fixed to the outside of the one wall surface 4 by a bolt 37. Since the locking body 35 is configured to move up and down by tightening the bolt 37, for example, when the medicine 22 to be stored is changed and the length of the medicine is shortened, the bolt 37 is loosened and engaged. The stop body 35 can be corrected downward, and can deal with various drugs.
[0018]
In the medicine container such as a tablet having the above-described structure, a high part 15a having a high one end and a low part 15b having a low other peripheral part are formed on the core 15 of the medicine stirring roller body 3 that rotates in the medicine container 7. Since the inclined portion 24 is formed, the stored medicine 22 is introduced into the sliding guide path 23 for sliding down to the lower portion 15b side of the inclined portion 24 by its own weight. Then, when the core body 15 rotates according to the rotation of the shaft core 11, the drug 22 accumulated on the low part 15b side is stirred on the high part 15a side from the locus of the inclined part 24, so that the drug 22 is on the low part 15b side. Without bridging, the discharge guide path 23 is reliably and quickly introduced and cascaded.
[0019]
Further, by appropriately changing the large gear 21 and the small gear 26 or the double large and small gears 28, the core body 15 fixed to the shaft core 11 and the cylindrical body 12 provided with the discharge guide path 23 are provided. If they are rotated at different rotational speeds, the medicine 22 can be quickly and evenly introduced into the discharge guide path 23. That is, when the core body 15 and the cylinder body 12 rotate at the same speed, the lower portion 15b side of the core body 15 is out of 10 discharge guide paths 23 formed on the outer peripheral side of the cylinder body 12. It rotates in a state of being always associated with one discharge guide path 23, but when rotating at different speeds as described above, the lower portion 15b side of the core body 15 is associated with all the discharge guide paths 23. It will be different. Therefore, the medicine 22 introduced into the discharge guide passage 23 while sliding down the inclined portion 24 of the core body 15 toward the low portion 15b is quickly and evenly introduced into all the discharge guide passages 23. It is.
[0020]
In the above embodiment, the drug inlet 1a is provided at the upper part of the drug container main body 1. However, the drug inlet 1a is not necessarily provided at the upper part of the drug container main body 1. As shown in FIG. 4, it may be provided on the other wall surface 5 of the medicine container main body 1. The other wall surface 5 refers to a surface exposed to the outer side 2a of the drug selection / supply device when the drug storage container is mounted in multiple stages on the drug storage container support 2 in the drug selection / supply device. When the drug inlet 1a is provided on the other wall surface 5 in this way, the drug container main body 1 can be removed without removing the drug container from the drug container support 2 when adding or changing drugs such as tablets. There is an advantage that the medicine can be introduced simply by opening and closing the lid 1b.
[0021]
Furthermore, in the above embodiment, the core body 15 and the cylinder body 12 of the medicine stirring roller body 3 only rotate around the axis 11 provided substantially vertically on the medicine container support 2. However, in addition, the core body 15 or the cylinder body 12 or both of them (the drug stirring roller body 3) may move up and down. As described above, if at least one of the core body 15 and the cylindrical body 12 is configured to move up and down, the medicine 22 is also stirred in the vertical direction, so that the discharge guide path 23 can be more reliably and quickly discharged. There is an effect that the drug 22 is introduced.
[0022]
Further, in the above embodiment, the rotation driving device 30 is provided on the medicine container supporting body 2, but this is not necessarily the case. For example, the rotation driving device 30 is a medicine container main body. 1 may be provided, or may be provided on both the drug container support 2 and the drug container main body 1.
[0023]
In the above embodiment, the drug 22 is illustrated as an elliptical capsule. However, the drug 22 is not necessarily limited to an elliptical capsule, and may be a thin cylindrical, spherical, elliptical tablet or the like. Also good. Any drug having a fixed shape in a normal state called a so-called tablet may be used. Therefore, if the shape of the tablet is different, it goes without saying that the shape of the discharge guide path 23 and the like in the above embodiment must be changed as appropriate, and the drug container according to the present invention is in its use mode. The design is appropriately changed and used.
[0024]
【The invention's effect】
