The operation of the medicine supply apparatus 1 of the present invention having the above configuration will be described. It is assumed that the shutters 53, 53 are closed when the power is turned on. Further, it is assumed that the shelves 2 ... With the tablet cases 3 ... Respectively containing predetermined medicines are attached in the case accommodating portion 8 of the upper structure 7A as described above. .

Next, when the medicine supply device 1 is turned on,
The microcomputer 97 of the control device 95 uses the identification sensors 33, ... To detect the case 8 of the upper structure 7A.
The identification codes of the tablet cases 3 ... of the shelves 2 ... As a result, the data relating to the type of drug stored in each tablet case 3 is stored together with the position of the tablet case 3, and this data is also transmitted to the personal computer PC.

It should be noted that the microcomputer 97 has a database relating to the type of drug in each tablet case 3 ... Stored in the case storage portion 8 and the position of the tablet case 3, and the database is a personal computer PC. It has been sent to. The identification code read by the identification sensor 33 ... Is also added to this database.

First, the dispensing operation will be described. When an operator inputs prescription data from the personal computer PC based on a doctor's prescription, the microcomputer 97 of the drug supply device 1 causes the tablet case 3 in which the drug specified based on the prescription data is stored from the database. Then, the drum motor 14 is normally rotated by the driver 94, and the discharge drum 23 is rotated (normally rotated) to rotate the vertical groove 2
The medicines in 4 are discharged to the discharge port 21 one by one.

At this time, the microcomputer 97 inputs a drug detection signal from the drug detection sensor 18 and counts the discharged drug. Then, the drum motor 14 is stopped when the predetermined amount is discharged. The discharged drug is discharged from the chute 19 to the chute 3 constituted by the passage 9.
2 enters and is temporarily received by the shutter 53.

Then, the microcomputer 97 energizes the shutter solenoid 64 to open and close the opening / closing plate 63 as described above.
A and 63B are opened (FIG. 27), the medicine is dropped into the hopper 54, the medicine is put into the wrapping paper 72 through the nozzle 74, and is packed in the packing machine 13 as described above, and then the takeout port 82. More externally. At this time, when the medicine drops from the shutter 53 to the hopper 54, the next medicine is discharged, whereby the microcomputer 97 shortens the time required for packaging. The above-mentioned printing on the medicine to be packed is performed by the printer 73 before the medicine is put in.

Here, in the case of the embodiment, 320 tablet cases 3 ... Are stored in the case storage portion 8. Therefore, although a maximum of 320 kinds of medicines can be supplied and packaged, if the kinds of medicines to be handled cannot fit in the case storage section 8, the shelves located at the left and right ends of the case storage section 8 can be carried out. The storage container 51 (side wall side of the case storage portion 8) of each tablet case 3 of 2 ... is replaced with the storage container 51 in which a necessary type of drug is stored. The identification code of the exchanged storage container 51 is also read by the identification sensor 33 and input to the microcomputer 97. Then, the read data of the new drug is also added to the database.

At this time, when the tablet case 3 for one or more kinds of medicines to be put in is not present in the case storage section 8, the microcomputer 97 transmits data to the personal computer PC and the tablet is displayed on the screen of the personal computer PC. A guide is displayed for the replacement of Case 3. At that time, the microcomputer 97 transmits data to the personal computer PC,
The position (address) of the storage container 51 of the tablet case 3 that can be removed is displayed on the screen. This allows
For example, when a plurality of types of medicines are put into one sachet, in order to attach a non-existing medicine storage container 51, the storage container 51 in which another medicine to be put in the sachet is stored is removed. Avoid the inconvenience.

Next, the microcomputer 97 controls the driver 94 to periodically perform reverse rotation of the drum motor 14 for a predetermined short time (for example, 10 ms), and then perform normal detection for the same time. Each time of reverse rotation / normal rotation in this abnormality detection operation is set to be sufficiently shorter than the time interval (medicine discharge interval) in which the vertical groove 24 is aligned with the discharge port 21 by the rotation of the discharge drum 23.

Then, the microcomputer 97 uses the current transformer 96 to take in the value of the energizing current of the drum motor 14 during this abnormality detecting operation. If no current is flowing, the winding of the drum motor 14 is broken. It is determined that the alarm is present and the alarm action is executed. The alarm data is transmitted to the personal computer PC and displayed on the screen. This abnormality detection operation applies to all tablet cases 3.
Are sequentially performed for the drum motor 14 of. In this case, as described above, each time of reverse rotation / normal rotation in the abnormality detection operation is sufficiently shorter than the medicine discharge interval, so that the medicine is not discharged.

In particular, since the drum motor 14 is first rotated in the reverse direction, the previous discharging operation (drum motor 1
(4 is normal rotation) and the medicine is about to fall from the vertical groove 24 to the outlet 21, the medicine is mistakenly discharged from the outlet 21.
There is no inconvenience of being discharged.

Further, the microcomputer 97 energizes the keep solenoids 42 corresponding to the shelves 2 in one row to all the rows specified by the input operation to the personal computer PC based on the command data from the personal computer PC, and the plungers. 42A
To be locked backwards. As a result, all the shelves 2 in the row (including all rows) corresponding to the keep solenoid 42 cannot be pulled out as described above (FIG. 2).
2). The lock is released by energizing the keep solenoid 42 in the opposite direction based on the input operation to the personal computer PC. At this time, the plunger 42A is sucked as described above (FIG. 23).

In this case, the operation access right for locking and unlocking is set in the personal computer PC by the user (password or the like). Thereby, it is possible to avoid the inconvenience that the shelf 2 is pulled out carelessly and different medicines are stored in the tablet case 3, and the safety of the dispensing work can be ensured.

Here, the microcomputer 97 determines whether the stay 34 is in the released state or the regulated state by the lock sensor 43, and any shelf 2 is pulled out, and the stay 34 is regulated. The above-mentioned lock operation is not executed for the keep solenoid 42 corresponding to the row in the state. This avoids the inconvenience that the lock member 41 of the stay 34 in the restricted state is caught by the plunger 42A of the keep solenoid 42 and cannot be rotated.

As described above, the keep solenoid 42 is
The locked state can be manually released by pulling the lock release lever 44. It should be noted that only a limited number of people need to know the lock release lever 44. For example, it can be operated only from the lower structure 7B side. Thus, even if the keep solenoid 42 fails and the locked state cannot be released, the drawer 2 of the shelf 2 is not hindered.

Further, in the above-mentioned medicine discharging / packing operation, the microcomputer 97 operates the respective drum motors 14
The operating time of ... Is added up. Further, the microcomputer 97 uses the shutter solenoids 64,
64 and keep solenoid 42 operation times, packaging machine 13
Heat seal head 76, thermal transfer head 9 of printer 73
The number of operations such as 3 is added up. Furthermore, the service life limit values of these consumable parts are input and set in the microcomputer 97.

Then, the microcomputer 97 transmits failure forecast data to the personal computer PC when the operating time or the number of times of operation of these consumable parts approaches the service life limit value or when the service life limit value is reached. Then, it is displayed on the screen of the personal computer PC that the risk of failure of the consumable part has increased. As a result, the user has approached or reached the end of its useful life in advance, the drum motor 14, the shutter solenoid 64, and the keep solenoid 4.
