Is rotated by the motor 14.

On the outer circumference of the inner drum 4b, a plurality of drug feeders 20 which are provided adjacent to each other in the circumferential direction are provided in multiple stages in the vertical direction.

Since the medicine feeder 20 has the same structure as the medicine feeder 20 provided on the outer periphery of the outer drum 4a, the same parts are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 3, the medicine feeder 20 is used.
The medicine discharged from the medicine outlet 27 into the passage 28 falls into the discharge passage 6 through the window 29 formed in the outer wall of the rectangular tube 5.
As shown in FIG. 2, the lower end of the discharge path 6 communicates with a drop hole 9 formed in the lower disk 8.

Below the two drums 4a and 4b, a hopper 30 'for collecting a medicine is provided. Hopper 3
The outlet 31 'provided at the bottom of 0'is the drum 4a, 4b
Are arranged on the central axis of The medicine falling from the outlet 31 'of the hopper 30' is packaged by the packaging device 40 provided below it.

Here, the packaging device 40 is provided with a triangular plate body 41 in the transfer path of the heat-fusible packaging paper S, and the packaging paper S is bent into a V-shape in the width direction by the plate body 41. The plate 41
And a pair of heating rolls 42 provided on the front side thereof, a bag portion is formed. When a medicine is supplied to the bag portion from the hopper outlet 31 ', the packaging paper S is fed, and the pair of heating rollers 42 is fed during the feeding. Is rotated at the same speed as the packaging paper S so that the width direction of the folded packaging paper S and both side edges are simultaneously heat-bonded in a strip shape.

The medicine storing / extracting device shown in the embodiment has the above-mentioned structure, and this device operates the medicine feeder 20 through the control device, and the medicine feeder 20 of the outer drum 4a.
The medicine sent from the medicine is dropped from the discharge path 51 onto the hopper 30 ', and the medicine feeder 2 of the inner drum 4b is also dropped.
The medicine sent from 0 is dropped onto the hopper 30 ′ from the discharge path 6 of the inner drum 4b.

At this time, the drop position on the hopper 30 'of the drug delivered from the drug feeder 20 of the outer drum 4a and the drop position on the hopper 30' of the drug delivered from the drug feeder 20 of the inner drum 4b. Although different, the distance between both drop positions is a short length that is substantially equal to the width dimension of the medicine feeder 20, so that the hopper exit 31 ′ from the drop position is different.
It is possible to substantially uniformize the discharge time of the medicine leading to.

When replenishing the medicine to the medicine feeder 20 of the outer drum 4a, the outer drum 4a is rotated to move the medicine feeder 20 requiring replenishment to a predetermined position where the medicine can be replenished, and then the medicine storage case 22 is moved. Remove,
Supply medicine inside.

Further, the drug feeder 20 of the inner drum 4b
At the time of replenishment of the medicine to the inner drum 4b, the inner drum 4b is rotated so that the medicine feeder 20 requiring replenishment is moved to the outer drum 4
After being stopped at a position facing the separating portion 50 of a, the medicine storing case 22 of the medicine feeder 20 is separated from the separating portion 50.
Remove and replenish the drug.

At this time, the outer drum 4a is stopped and the separating portion 50 is held at a predetermined position. In order to regulate the stop position of the detaching portion 50, as shown in FIG. 1, a position detection piece 61 is provided on the outer drum 4a, and when the position detection sensor 62 detects the position detection piece 61, the outer drum 4 is detected.
The drive device 55 of a is stopped.

In the medicine storing / extracting device shown in the embodiment, the drums 4a and 4b are formed by a plurality of rectangular cylinders 5 and 5a. However, the drums 4a and 4b are not limited to this, and for example, a single wall structure. The medicine may be dropped along the inside of the wall.

[0039]

Since the present invention is constructed as described above, it has the following effects.

The inner drum is rotated by the operation of the drive device, and the inner drum is stopped when the medicine feeder requiring replenishment of the medicine is rotated to the position of the detaching portion of the outer drum, and at the position of the detaching portion, the medicine feeder is stopped. Since the medicine is replenished to the inside, the medicine can be efficiently supplied to the medicine feeder on the inner drum. Further, since the outer drum is rotated so that the outer drum is stopped to supply the medicine when the medicine feeder requiring the medicine supply is rotated to a predetermined position, the medicine feeder of the outer drum is also supplied. The drug can be efficiently replenished.

Since it is sufficient to secure a space for supplying the medicine at one place on the outer periphery of the outer drum, it is possible to reduce the installation space of the medicine storing and extracting device.

By regulating the stop position of the detaching portion of the outer drum by the position detecting means, it is possible to more efficiently replenish the medicine to the medicine feeder of the inner drum.
