Further, in the case storage portion 8 of the upper structure 7A, the shelves 2 to which the tablet cases 3 to store predetermined medicines are respectively attached are attached as described above. .
[0053]
Next, when the medicine supply device 1 is turned on, the microcomputer 97 of the control device 95 causes the respective shelves 2... Located at the left and right ends of the case housing portion 8 of the upper structure 7A by the identification sensors 33.・ Read the identification code of each tablet case 3. Thereby, the data regarding the kind of medicine accommodated 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.
[0054]
The microcomputer 97 has a database concerning the types of medicines in each tablet case 3... Stored in the case storage unit 8 and the position of the tablet case 3, and the database is also transmitted to the personal computer PC. It is assumed that The identification codes read by the identification sensors 33... Are also added to this database.
[0055]
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 medicine supply device 1 stores the tablet case 3 containing the medicine designated based on the prescription data from the database. The drum motor 14 is rotated forward by the driver 94 and the discharge drum 23 is rotated (forward rotation) to discharge the medicine in the vertical groove 24 one by one to the discharge port 21.
[0056]
At this time, the microcomputer 97 inputs a drug detection signal from the drug detection sensor 18 and counts the discharged drug. Then, when the predetermined amount is discharged, the drum motor 14 is stopped. The discharged medicine enters the chute 32 constituted by the passage 9 from the discharge chute 19 and is temporarily received by the shutter 53.
[0057]
The microcomputer 97 energizes the shutter solenoid 64 to open the open / close plates 63A and 63B as described above (FIG. 27), drops the medicine into the hopper 54, and places the medicine into the wrapping paper 72 through the nozzle 74. After being charged and packaged by the packaging machine 13 as described above, it is sent out from the outlet 82. At this time, by discharging the next medicine when the medicine falls from the shutter 53 to the hopper 54, the microcomputer 97 shortens the time required for packaging. In addition, the above-described printing regarding the medicine to be packaged is performed by the printer 73 before the medicine is introduced.
[0058]
Here, 320 tablet cases 3... Are stored in the case storage unit 8 in the case of the embodiment. Accordingly, the supply and packaging of up to 320 kinds of medicines can be performed, but when the kinds of medicines to be handled cannot fit into the case storage portion 8, the shelves positioned at the left and right ends of the case storage portion 8 are used. The storage container 51 of each tablet case 3 (side wall side of the case storage unit 8) is replaced with a storage container 51 in which a necessary type of medicine 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 new drug data is also added to the database.
[0059]
At this time, if the tablet case 3 of one kind or a plurality of kinds of medicines to be loaded does not exist in the case storage unit 8, the microcomputer 97 transmits data to the personal computer PC and displays the tablet case 3 on the screen of the personal computer PC. Display the replacement guide. At that time, the microcomputer 97 transmits data to the personal computer PC, and guides and displays the position (address) of the storage container 51 of the tablet case 3 that may be removed on the screen. Thereby, for example, when a plurality of types of medicines are put into one package, in order to attach a container 51 for a medicine that does not exist, the storage container 51 in which other medicines to be put into the package are stored. To avoid the inconvenience of being removed.
[0060]
Next, the microcomputer 97 controls the driver 94 to execute an abnormality detection operation that periodically reverses the drum motor 14 for a predetermined short time (for example, 10 ms), and then performs normal rotation for the same time. Each time of reverse rotation / forward rotation in this abnormality detection operation is set to be sufficiently shorter than the time interval (drug discharge interval) at which the vertical groove 24 matches the discharge port 21 by the rotation of the discharge drum 23.
[0061]
The microcomputer 97 takes in the energization current value of the drum motor 14 during the abnormality detection operation by the current transformer 96, and when the current is not flowing, the winding of the drum motor 14 is disconnected. Judgment is made and alarm action is executed. The alarm data is transmitted to the personal computer PC and displayed on the screen. This abnormality detection operation is sequentially performed on the drum motors 14 of all the tablet cases 3. In this case, as described above, each time of reverse rotation and normal rotation in the abnormality detection operation is sufficiently shorter than the discharge interval of the drug, so that the drug is not discharged.
[0062]
In particular, since the drum motor 14 is first rotated in the reverse direction, even when the medicine is falling from the longitudinal groove 24 to the discharge port 21 in the previous discharging operation (the drum motor 14 is rotating in the forward direction), this medicine is used. Is not accidentally discharged to the discharge port 21.
[0063]
Further, the microcomputer 97 energizes the keep solenoids 42 corresponding to the shelf 2 in the first row to the whole row specified by the input operation to the personal computer PC based on the command data from the personal computer PC, and moves the plunger 42A rearward. Project to the locked state. 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. 22). The unlocking is also performed by energizing the keep solenoid 42 in the reverse direction based on an input operation to the personal computer PC. At this time, the plunger 42A is sucked as described above (FIG. 23).
[0064]
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). As a result, it is possible to avoid inconveniences such as the shelf 2 being pulled out carelessly and different medicines being stored in the tablet case 3.
[0065]
Here, the microcomputer 97 determines whether the stay 34 is in the release state or the restriction state by the lock sensor 43, and any of the shelves 2 is pulled out, and the stay 34 is in the restriction state. The above-described locking operation is not executed for the keep solenoids 42 corresponding to the current row. 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.
[0066]
As described above, the locked state of the keep solenoid 42 can be released manually by pulling the lock release lever 44. Thus, even if the keep solenoid 42 breaks down and the locked state cannot be released, measures are taken so as not to hinder the drawer 2 from being pulled out.
[0067]
Further, the microcomputer 97 accumulates the operation time of each drum motor 14... In the above-described medicine discharge / packaging operation. Further, the microcomputer 97 accumulates the number of operations of the shutter solenoids 64 and 64 and the keep solenoid 42 and the number of operations of the heat seal head 76 of the packaging machine 13 and the heat transfer head 93 of the printer 73, respectively. Further, the service life limit values of these consumable parts are input and set in the microcomputer 97.
[0068]
Then, the microcomputer 97 transmits failure prediction data to the personal computer PC when the operating time or the number of times of operation of these consumable parts approaches or reaches the durable limit value. It is displayed on the PC screen that the risk of the consumable part being broken has increased. As a result, the user can replace the drum motor 14, the shutter solenoid 64, the keep solenoid 42, the heat seal head 76, and the thermal transfer head 93 that have already approached or reached the service life limit. Thus, it becomes possible to avoid a delay in providing medicine due to failure of these consumable parts.
[0069]
Here, FIG. 35 shows an extension unit 98 that can be attached to the medicine supply apparatus 1. For example, in the case of a large-scale hospital or the like, there are cases where 320 tablet cases 3... In the state of FIG. Therefore, in such a case, the top plate 1A of the upper structure 7A is removed, and the extension unit 98 is connected and fixed on the upper structure 7A opened on the upper surface (the top plate 1A is attached to the upper surface of the extension unit 98). The extension unit 98 is provided with four shelves 2... As a result, the number of tablet cases 3 increases by 64.
[0070]
And the passage 9 of each shelf 2... Corresponds to the upper end of the shelf 2... Of the upper shelf 2. Configure. The drum motor 14 and the agent detection sensor 18 of each tablet case 3 of the extension unit 98 are also connected to the microcomputer 97, and the discharging operation similar to that described above is executed.
[0071]
Here, a shelf 2A having a height twice as large as the above-described shelf 2 as shown in FIG. In this case, a tablet case 3A having a large-capacity storage container 51A as shown in each drawing is attached to the shelf 2A. FIG. 36 shows an example in which a normal tablet case 3 and a large-capacity tablet case 3A are attached together, and FIG. 37 shows an example in which only a large-capacity tablet case 3A is attached. The harness 28 is connected to the connector.
[0072]
Further, a shelf 2B on which a tablet case 3B for half tablets (tablets lacking in half) as shown in FIG. The harness 28 is also connected to the shelf 2B by a connector. Furthermore, a shelf 2C to which a tablet case as shown in FIG. 39 is not attached can be installed in the case storage portion 8 so that it can be pulled out. On the shelf 2C, for example, a medicine before unpacking packed in cardboard is placed, but naturally the harness is not connected.
[0073]
As described above, since various shelves such as the shelves 2A and 2B to which different tablet cases are attached or the shelves 2C to which the power source is not connected can be drawn out in the case storage unit 8, the medicine supply device 1 Convenience is significantly improved.
[0074]
In the embodiment, the data input to the medicine supply device 1 is performed by a separate personal computer PC. However, the present invention is not limited to this, and in addition, the control panel 111 is attached to the door panel 6 of any shelf 2. From there, data such as a prescription may be input, or an alarm display may be displayed there.
[0075]
In the embodiment, the door panel 6 is attached to each of the plurality of shelves 2... Stored in the case storage portion 8 so as to be freely drawn out, thereby closing the front opening of the upper structure 7A (case storage portion 8). However, the present invention is not limited to this, and as shown in FIG. 40, no door panel is attached to each shelf 2... May be. In this case, the lock operation for prohibiting the drawer of all the shelves 2... Is achieved by locking the upper panels 112 and 112.
[0076]
