The operation of is controlled by the control device 95.

Next, an example of the processing of the control device 95 will be described in detail. This example shows a case where a dispensing process for two kinds of drugs using a drug container and an introduced drug container is performed.

Dispensing data related to the dispensing process is input according to the prescription information via the interface unit 91 and stored in the control device 95. Examples of the dispensing data include the type of drug used for the dispensing process, the daily dose, the number of doses per day, the number of days taken, and the like. When the dispensing data is input, the drug packaging device starts the dispensing process.

When the dispensing process is started, in order to take out the drug container containing the drug used for the dispensing process from the container storage unit 11, the control device 95 attaches a holding arm to the container arranging unit 13 in which the drug container is arranged. Bring the tip of the portion 16 closer. In the following description, the drug container may be referred to as a first drug container.

The control device 95 rotates the rotating member 12 to adjust the position of the container arranging portion 13 in which the first drug container is arranged. As a result, the first drug container can be taken out from the container arranging portion 13 at the tip end portion of the holding arm portion 16 provided in the container transport portion 15. At the timing T1 shown in FIG. 2, the control device 95 rotates the container storage unit 11 while the holding arm unit 16 is being moved. By simultaneously moving the holding arm portion 16 and adjusting the position of the container arranging portion 13 in this way, the transfer work of the drug container becomes smooth.

The control device 95 controls the container transport unit 15 to take out the first drug container from the container arrangement unit 13.

When the tip of the holding arm portion 16 holds the first drug container, the control device 95 controls the container transport section 15 to transport the first drug container to the drug discharge section 21 in which the drug container is not set and set it. do. Hereinafter, in order to specify each of the two drug discharge units 21, they may be referred to as a first drug discharge unit and a second drug discharge unit. In the present embodiment, the first drug container is set in the first drug discharge section 21.

When the first drug container is set in the first drug discharge section 21, the control device 95 transfers the data stored in the information tag of the first drug container to the first reader / writer section 71 of the first drug discharge section 21. To read. The data read at this time includes, for example, data regarding unique identification information, drug information, and weight information.

In the control device 95, the first drug container set in the first drug discharging section 21 stores the drug used for the dispensing process based on the unique identification information or the drug information acquired by the first reader / writer section 71. Determine if it matches the drug container. Further, the control device 95 determines whether or not an amount of the drug required for the current dispensing process or more is contained in the drug container based on the weight information of the drug acquired by the first reader / writer unit 71.

When it is confirmed that the drug container set in the first drug discharge unit 21 is correct and that the drug container contains more drugs than necessary for the dispensing process, the control device 95 discharges the first drug. The vibrating device 22 of the unit 21 is started to vibrate, and the distribution pan 31 is rotated (end of timing T2). As a result, the drug is shaken out from the first drug container.

The drug shaken out from the first drug container is discharged onto the rotating distribution dish 31. Therefore, the drug is placed on the distribution dish 31 so that the thickness is uniform on the distribution dish 31.

In the process of discharging the drug from the first drug container by the first drug discharging unit 21, the first measuring unit 62 continues to measure the weight of the drug in the first drug container. As the shaking of the drug from the first drug container progresses, the weight of the drug in the first drug container gradually decreases. When the decrease value of the weight of the drug in the first drug container becomes equal to the weight value of the drug used for the dispensing process, the control device 95 stops the vibrating device 22 of the first drug discharge unit 21 and causes the first drug. The discharge of the drug from the discharge unit 21 is completed. In this way, the control device 95 monitors the change in the weight of the drug in the first drug container during the discharge operation. As a result, the amount of the drug required for the present dispensing process can be accurately discharged from the first drug container.

The drug used for the dispensing process may not be contained in the drug container. In addition, the amount of the drug contained in the drug container may be insufficient for the amount required for the dispensing process. In such a case, when the dispensing process is started, the control device 95 informs the user that the drug should be contained in the introduction drug container and introduced into the drug supply device 1.

In the following description, the introduced drug container containing the drug may be referred to as a second drug container.

A second drug container is arranged in the container temporary storage portion 81. The drug is charged into the second drug container arranged in the container temporary storage portion 81. Here, the measurement work is performed by the user.

The second measuring unit 63 measures the weight of the medicine in the second medicine container arranged in the container temporary storage unit 81. When the weight value of the drug in the second drug container becomes equal to the weight value of the drug used for the dispensing process, the measurement work is completed. Upon completion of the measurement work, the second measurement unit 63 transmits the measurement result to the control device 95. The control device 95 stores the weight value of the drug in the second drug container in association with the dispensing data related to the current dispensing process.

The control device 95 guides the user to allow the drug supply device 1 to introduce the drug.

The second drug container is set in the drug discharging section (second drug discharging section 21) on the side of the two drug discharging sections 21 in which the first drug container is not set.

The setting of the second drug container to the second drug discharging unit 21 may be performed manually by the user. Further, the container transport unit 15 shown in FIG. 1 may be configured to manually transport the second drug container set in the container temporary storage section 81 to the second drug discharge section 21. In this case, when the tip of the holding arm portion 16 holds the second drug container, the control device 95 controls the container transport section 15 to transport the second drug container to the drug discharge section 21 in which the drug container is not set. And set.

When the second drug container is arranged in the container temporary storage section 81, the control device 95 causes the second reader / writer section 75 to read the unique identification information stored in the information tag of the second drug container (timing T3). ). With the completion of the measurement work by the second measurement unit 63, the second reader / writer unit 75 transmits the unique identification information to the control device 95. The control device 95 stores the unique identification information in association with the dispensing data related to the current dispensing process.

When the second drug container is set in the second drug discharge unit 21, the control device 95 performs the process as shown in FIG. 3 in the present embodiment. That is, first, the unique identification information stored in the information tag of the second drug container is read by the first reader / writer section 71 of the second drug discharge section 21 (timing T4) (step S1). Further, the control device 95 causes the first measuring unit 62 to measure the weight of the drug in the second drug container (step S2).

In the control device 95, the second drug container set in the second drug discharge section 21 based on the unique identification information acquired by the first reader / writer section 71 is an introduced drug container in which the drug used for the dispensing process is stored. It is determined whether or not it matches with (step S3). Further, the control device 95 determines whether or not the amount of the drug required for the present dispensing process is contained in the second drug container based on the weight of the drug measured by the first measuring unit 62 (step S4). ).

In the present embodiment, when the total amount of the drug shown in the dispensing data and the measurement result of the first measuring unit 62 match, the amount of the drug required for the current dispensing process is stored in the second drug container. It is determined that there is. On the other hand, if the total amount of the drug shown in the dispensing data and the measurement result of the first measuring unit 62 do not match, it is determined that the amount of the drug required for the current dispensing process is not contained in the second drug container. do. Even if the two do not match, if the measurement result of the first measuring unit 62 is larger than the total amount of the drug shown in the dispensing data, the amount of the drug required for the current dispensing process is placed in the second drug container. It may be determined that it is contained.

Based on whether or not the measurement results of the first measuring unit 62 and the second measuring unit 63 match, the control device 95 determines whether or not the amount of the drug contained in the second drug container has increased or decreased. May be. This determination can be realized, for example, as follows. When the second reader / writer unit 75 acquires the unique information of the introduced drug container and the second measuring unit 63 measures the weight of the drug, the control device 95 uniquely obtains the obtained unique information and the drug weight and dispenses the dispensing data. It is stored in a table format, for example, in association with the identification information (ID) to be shown. After that, when the first reader / writer unit 71 acquires the unique information of the introduced drug container, the control device 95 refers to the above table based on this unique information, and the second measurement is performed in the introduced drug container of the unique information. The unit 63 can call up the weight of the drug measured in the past and the ID of the dispensing data. The measurement results are compared between the first measurement unit 62 and the second measurement unit 63, and if they match, the control device 95 determines that the amount of the drug contained in the second drug container has not increased or decreased. If they do not match, the control device 95 determines that the amount of the drug contained in the second drug container has increased or decreased.

When the weight measured by the first measuring unit 62 is larger than the weight measured by the second measuring unit 63, there is a possibility that a foreign substance is mixed in the second drug container when the drug is introduced. On the other hand, if the weight measured by the first measuring unit 62 is smaller than the weight measured by the second measuring unit 63, the drug may have spilled from the second drug container when the drug is introduced. By comparing the measurement results of the first measurement unit 62 and the second measurement unit 63, it becomes easy to capture a small change in weight.

When it is confirmed that the second drug container set in the second drug discharge unit 21 is correct and that the amount of the drug required for the dispensing process is contained in the second drug container, the control device 95 is set to the second drug container. 2 The vibrating device 22 of the drug discharging unit 21 is started to vibrate (end of timing T4). As a result, the drug is shaken out from the introduced drug container. In this way, the drug is discharged (step S5). In the example of FIG. 2, the discharge timings of the drugs in the first drug discharge section 21 and the second drug discharge section 21 overlap each other.

Next, when the amount of the drug required for the dispensing process is discharged from the first drug container, the control device 95 stops the vibration device 22 of the first drug discharge unit 21, and shakes the drug from the first drug container. Finish the delivery. After that, the control device 95 causes the first reader / writer unit 71 of the first drug discharge unit 21 to perform the writing process. That is, the control device 95 stores the weight data of the drug in the first drug container at the end of the shaking of the drug in the information tag of the first drug container (timing T5).

After the weight data is written in the information tag of the first drug container, the control device 95 controls the container transport unit 15 to return the first drug container to the container storage unit 11.

As shown in FIG. 2, the drug supply device 1 is based on the drug container (first drug container) whose discharge is completed when another drug container (in this example, the second drug container) is discharging the drug. Can be transported to the position of. In this way, the discharge of the drug and the movement of the drug container can be performed in parallel, so that the entire work can be performed quickly.

As described above, the drug supply device 1 can open the drug discharge unit 21 when the drug container discharges the drug. Then, in the drug supply device 1, even while the drug container (second drug container) is discharging the drug, the drug container used for the next dispensing process is emptied by the drug discharge unit 21 (first drug discharge unit 21). Can be set in advance. In this sense as well, the drug supply device 1 can efficiently perform the dispensing process.

As in the case of taking out the drug container from the container storage unit 11, the control device 95 rotates the rotating member 12 to adjust the position of the container arrangement unit 13 to which the first drug container should be returned. As a result, the first drug container can be returned to the container arranging portion 13 at the tip end portion of the holding arm portion 16. The rotation of the container storage unit 11 is performed until the movement of the holding arm unit 16 is completed, as in the case described above (timing T1) (timing T6). This facilitates the transfer work of the drug container.

Next, when the amount of the drug required for the dispensing process is discharged from the second drug container, the control device 95 stops the vibration device 22 of the second drug discharge unit 21, and shakes the drug from the second drug container. Finish the delivery.

When the discharge treatment of the drug from the first drug container and the second drug container is completed and the drug required for dispensing is placed on the distribution dish 31, the control device 95 puts the drug take-out unit 35 on the distribution dish 31. The drug is scooped up and the drug is charged into the hopper 42 of the packaging section 41 (timing T7). Further, the control device 95 packages the drug scooped by the drug take-out section 35 in the packaging section 41 (timing T7). Although the operation timing of the packaging unit 41 is omitted in FIG. 2, the packaging unit 41 operates at substantially the same timing as the drug extraction unit 35. As shown in FIG. 2, the drug supply device 1 can carry out a drug container transport operation while the drug take-out unit 35 is performing an operation of scooping up the drug (take-out operation). In this way, the scooping of the drug and the movement of the drug container can be performed in parallel, so that the entire work can be performed quickly.

When the process of scooping out the drug from the distribution plate 31 is completed, the distribution plate 31 is stopped. Then, the first cleaning unit 52 cleans the distribution plate 31 and the drug take-out unit 35 (timing T8). As shown in FIG. 2, the drug supply device 1 can perform a drug container transport operation while the first cleaning unit 52 is performing a cleaning operation (first cleaning operation). In this way, the cleaning work and the movement of the drug container can be performed in parallel, so that the entire work can be performed quickly.

In this way, the drug supply device 1 does not return the drug container to be used repeatedly from the drug discharge unit 21 to the container storage unit 11, so that the drug supply device 1 will use the drug container when performing the next dispensing process. It does not have to be transported from the container storage unit 11. As a result, the drug packaging device can smoothly perform the next dispensing process, and the operating time can be shortened.

When a new drug container to be used in the next dispensing process is taken out from the container storage unit 11, the control device 95 rotates the rotating member 12 to adjust the position of the container arrangement unit 13. As a result, the drug container can be taken out from the container arrangement portion 13 at the tip portion of the holding arm portion 16 provided in the container transport portion 15. Since the tip of the holding arm portion 16 is already located near the container storage portion 11, the rotation of the container storage portion 11 is performed in a state where the holding arm portion 16 is stopped (timing T10 in FIG. 2). .. However, the container storage unit 11 may be rotated while the holding arm unit 16 is moved.

As described above, the drug supply device 1 of the present embodiment includes a drug discharge unit 21, a first measurement unit 62, and a control device 95. The drug discharge unit 21 can set an introduced drug container introduced from the outside of the drug supply device 1, and discharges the drug contained in the set introduced drug container. The first measuring unit 62 measures the weight of the drug contained in the introduced drug container set in the drug discharging unit 21. The control device 95 controls the drug discharge unit 21 and the first measurement unit 62. When the introduced drug container containing the drug is set in the drug discharging unit 21 for the dispensing process, the control device 95 puts the drug discharging unit in the first measuring unit 62 before discharging the drug from the introduced drug container. The weight of the drug contained in the introduced drug container set in 21 is measured. The control device 95 determines whether or not the amount of the drug required for the dispensing process is contained in the introduced drug container (here, whether or not the values of both are the same). When the amount of the drug required for the dispensing process is contained in the introduced drug container, the control device 95 causes the drug discharging unit 21 to discharge the drug from the introduced drug container.

This makes it possible to discharge the drug from the introduced drug container after confirming that the amount of the drug contained in the introduced drug container matches the amount of the drug required for the dispensing process. Therefore, even when the introduced drug container is used, an accurate amount of the drug can be discharged.

Further, in the drug supply device 1 of the present embodiment, the control device 95 stores the dispensing data related to the dispensing process. The control device 95 makes the above-mentioned determination based on the dispensing data and the measurement result of the first measurement unit 62.

Thereby, the determination of the control device 95 can be performed with reference to the dispensing data.

Further, the drug supply device 1 of the present embodiment includes a second measurement unit 63. The second measuring unit 63 measures the weight of the drug contained in the introduced drug container before it is set in the drug discharging unit 21. In another example of the drug supply device 1, the control device 95 increases or decreases the number of drugs contained in the introduced drug container based on the measurement result of the first measurement unit 62 and the measurement result of the second measurement unit 63. Is determined.

When the introduced drug container is introduced into the drug supply device 1, there is a possibility that a foreign substance may be mixed in the introduced drug container or the drug may be spilled from the introduced drug container before the drug is discharged from the introduced drug container. There is. In the above example, the change in the weight of the drug contained in the introduced drug container is accurately grasped by comparing the measurement result of the second measurement unit 63 and the measurement result of the first measurement unit 62, and abnormally appropriate. Can be dealt with. In this way, the determination by the control device 95 can be performed by using the actual measurement results by the two measurement units.
