The drug container introduction response is a response to introduce the drug container 15 containing the required amount of drug into the drug packaging device 1.

There are various ways for the guide unit 65 to provide guidance to the operator, but for example, it may be possible to display an appropriate message on the display unit 21. The guidance may be provided by, for example, audio or a notification lamp.

The hopper 35a is removable from the housing of the medicine packaging device 1. The locking mechanism 52 locks the hopper 35a and prevents it from being removed from the medicine packaging device 1. By unlocking the locking mechanism 52, the hopper 35a can be removed from the medicine packaging device 1, and can be moved to the outside of the housing of the medicine packaging device 1. Locking and unlocking of the hopper 35a by the locking mechanism 52 are controlled by the control unit 50.

The imaging device 54 is arranged above the hopper 35a. The imaging device 54 is capable of imaging the inside of the hopper 35a. The imaging device 54 may be able to reciprocate between a position directly above the hopper 35a and a position away from directly above the hopper 35a. The imaging device 56 is attached to the top of the cleaning section 56. The imaging device 56 can take an image of the container accommodated in the cleaning section 38. The imaging devices 54 and 56 are controlled by a control section 50. Images captured by the imaging devices 54 and 56 are displayed on the display unit 21. The control unit 50 receives images captured by the imaging devices 54 and 56, and outputs a control command to display the images to the display unit 21.

Next, various positions set in the medicine packaging device 1 will be explained with reference to FIG. 2. Any of these positions can be a source and a destination for the container to be transported by the transport unit 14.

The first standby position P1 is a position in the first storage section 11 where the intermediate container 91 that does not contain medicine can stand by. The first standby position P1 can also be called a storage position where a plurality of intermediate containers 91 are stored in the first storage section 11.

The second standby position P2 is a position in the second storage section 12 where the external medicine container 92 that does not contain medicine can stand by. The second standby position P2 can also be called a storage position where a plurality of external medicine containers 92 are stored in the second storage section 12.

The third standby position P3 is a position in the third storage section 13 where the delivery container 93 that does not contain medicine can stand by. The third standby position P3 can also be called a storage position where a plurality of carry-out containers 93 are stored in the third storage section 13.

The measuring position P4 is a position where the measuring section 18 measures the medicine contained in the intermediate container 91 or the carry-out container 93.

The first take-out position P5 is a position for taking out the intermediate container 91 or the carry-out container 93 to the outside of the medicine packaging device 1. For example, when measuring a drug from the drug container 15 to the intermediate container 91 or the delivery container 93 in the weighing unit 30, the amount to be taken out may be due to an insufficient amount of drug stored in the drug container 15, etc. To take out the intermediate container 91 or delivery container 93 containing the drug that does not meet the target amount to the outside of the drug dispensing device 1 when the measured amount is insufficient for the target amount for all doses. In this case, the first extraction position P5 is used. This extraction is performed via the first extraction section 25 provided in the medicine packaging device 1.

In this embodiment, the first take-out position P5 is set to a different position from the measuring position P4. The present invention is not limited to this, and, for example, the measurement position P4 may also be set to serve as the first take-out position P5.

The second take-out position P6 is for taking out the external drug container 92 before storing the drug to the outside of the drug packaging device 1 when measuring the drug using the measuring device 80 instead of the drug packaging device 1. It's the location. This extraction is performed via the second extraction section 26 provided in the medicine packaging device 1. The second take-out position P6 may also serve as a setting position (introduction position) for introducing the external medicine container 92 or intermediate container 91 containing the medicine measured by the measuring device 80 into the medicine packaging device 1.

The third take-out position P7 is a position for taking out the carry-out container 93 to the outside of the medicine packaging device 1. For example, when the drug is measured but not packaged in the drug dispensing device 1, the delivery container 93 containing the drug measured by the weighing section 30 is taken out of the drug dispensing device 1. In this case, the third extraction position P7 is used. This extraction is performed via the third extraction section 27 provided in the drug packaging device 1.

The supply standby position P8 is a position where the intermediate container 91 is kept on standby after the measuring unit 30 completes measuring the medicine and before the dispensing unit 33 discharges the medicine from the container and supplies it to the distribution tray 34a. It is. The supply standby position P8 is also a position (introduction position) where the external medicine container 92 or the intermediate container 91 containing the medicine measured by the measuring device 80 is set to be introduced into the medicine packaging device 1. The supply standby position P8 is set at the supply standby section 23 described above. The supply standby position P8 may also serve as the first take-out position P5, the second take-out position P6, or the third take-out position P7.

The supply position P9 is the position of the intermediate container 91 or the external medicine container 92 when the medicine is supplied to the distribution tray 34a in the medicine discharge section 32. The second transport unit 14b transports the intermediate container 91 from the supply standby position P8 to the supply position P9. When introducing an external drug container 92 or an intermediate container 91 containing a drug into the drug packaging device 1 from outside the drug packaging device 1, the introduction position of the container is set to the supply position P9, and the operator It is also possible to set the container directly to the medicine discharge section 32. As described above, the medicine packaging device 1 includes a plurality of (specifically, four) medicine discharge parts 32, and the four medicine discharge parts 32 are assigned the supply position P9.

The cleaning standby position P10 is a position where the intermediate container 91 or the external drug container 92 waits for cleaning in the cleaning section 38. The cleaning standby position P10 is set at the cleaning standby section 37 described above.

The cleaning position P11 is a position where the intermediate container 91 or the external drug container 92 is cleaned by the cleaning section 38.

In this embodiment, the supply standby position P8 and the cleaning standby position P10 function as relay points for transporting containers by the transport unit 14.

Specifically, the first conveying section 14a has the above-mentioned first standby position P1, second standby position P2, third standby position P3, weighing position P4, first take-out position P5, second take-out position P6, and The container is configured to be transportable between three take-out positions P7, a supply standby position P8, and a cleaning standby position P10. On the other hand, the second transport section 14b is configured to be able to transport containers between a supply standby position P8, a supply position P9, and a cleaning standby position P10.

Therefore, after the control unit 50 transports the intermediate container 91 etc. to the supply standby position P8 by the first transport unit 14a, the transported intermediate container 91 etc. is transported from the supply standby position P8 by the second transport unit 14b at an appropriate timing. can do. Further, after the intermediate container 91 and the like are transported to the cleaning standby position P10 by the second transport section 14b, the transported intermediate container 91 and the like can be transported from the cleaning standby position P10 by the first transport section 14a at an appropriate timing. .

In this embodiment, the configuration is such that the external drug container 92 stored in the second storage section 12 can be transported to the second take-out position P6 by the first transport section 14a and taken out to the outside of the drug packaging device 1. However, the external drug container 92 stored in the second storage section 12 may be taken out by the operator. In this case, the second storage section 12 may be provided outside the drug packaging device 1.

Next, the weighing device 80 will be explained. FIG. 6 is a schematic configuration diagram of the weighing device 80. As shown in FIG. 7, the weighing device 80 includes a control section 81, a weighing section 82, an information processing section 83, and a display section 84. The measuring section 82, the information processing section 83, and the display section 84 are each electrically connected to the control section 81. The metering device 80 is capable of metering the medication contained in the external medication container 92 . When the intermediate container 91 is used for external metering, the metering device 80 measures the drug contained in the intermediate container 91.

The control unit 81 can communicate with the control unit 50 of the medicine packaging device 1 and can receive the dispensing data stored in the storage unit 61 of the medicine packaging device 1. The weighing device 80 transmits the weighing result to the drug packaging device 1 when measurement (such as measuring a drug that is insufficient to a target amount) is completed.

The measuring section 82 has substantially the same configuration as the measuring section 18 of the medicine packaging device 1, so a description thereof will be omitted. The weighing device 80 weighs the medicine that the operator takes out from an appropriate medicine bottle or the like into a weighing pan or the like. Note that the measuring device 80 may measure the medicine for each external medicine container 92 while storing the medicine in the external medicine container 92.

The information processing section 83 is arranged near the measuring section 82. The information processing unit 83 includes a barcode reader and an RFID reader/writer. The barcode reader can read barcodes provided on the medicine bottles and the like. The RFID reader/writer can read the contents of the information recording section 92e of the external medicine container 92.

The information processing section 83 performs a process of reading information stored in the barcode of the medicine bottle or the like and the information recording section 92e of the external medicine container 92, respectively. Specifically, the information processing unit 83 reads medicine identification information of the medicine bottle or the like from a barcode provided on the medicine bottle or the like, and causes the control unit 81 to specify the medicine contained in the medicine bottle or the like. Further, the information processing section 83 reads container specific information stored in the information recording section 92e of the external medicine container 92. The weighing device 80 acquires the dispensing data corresponding to the read container specific information from the control unit 50 of the medicine packaging device 1 . At this time, the measuring device 80 also acquires information on the drug to be measured (including the target amount of the drug).

Then, the control unit 81 determines which of the drugs indicated by the drug information included in the dispensing data acquired from the control unit 50 of the drug packaging device 1 the drug identified based on the drug identification information corresponds to. Identify. When the control unit 81 determines that the medicine specified based on the medicine identification information matches any of the medicines indicated by the medicine information included in the dispensing data, the control unit 81 selects the medicine indicated by the matched medicine information as a measurement target. When the measurement of the drug selected as a measurement target is completed, the weighing device 80 sends the measurement results including the measured amount of the drug together with the dispensing data acquired from the control section 50 of the drug packaging device 1 via the control section 81. , is transmitted to the control unit 50 of the drug packaging device 1. The control unit 50 of the drug packaging device 1 receives the measurement results and updates the dispensing data stored in the storage unit 61.

The information processing section 83 can change the display content of the information display section 92d of the external medicine container 92. When the measuring device 80 finishes measuring the medicine, the information processing section 83 displays the measured amount (measurement result) on the information display section 92d of the external medicine container 92. Further, as information regarding the dispensing, the information display section 92d may display that the amount of medicine corresponding to the target amount is contained and that preparations are made for introduction into the medicine packaging device 1.

The display unit 84 is a device having a display screen capable of displaying characters and the like. The display section 84 is placed at an appropriate position on the weighing device 80. The display unit 84 can be configured as a display with a touch panel, for example. The display unit 84 can display, for example, the name of the drug, the target amount of the drug, the measured amount, and the like. Further, the display unit 84 can display the result of the determination made by the control unit 81 regarding whether or not the medicine in the medicine bottle or the like matches the medicine to be weighed out. This makes it possible to confirm that the medicine in the medicine bottle or the like is the required medicine based on the dispensing data.

Next, the processing of supplying and packaging drugs using the drug packaging device 1 will be described. FIG. 7 is a flow diagram showing the flow of drug supply and packaging processing.

First, as preparation, drug information is registered in the drug packaging device 1 (step S101). Specifically, information regarding the medicines packaged by the medicine packaging device 1 is stored in the storage unit 61 for each type of medicine. The display unit 50 may display a drug information registration screen on the display unit 21, and the operator may input drug information to this registration screen using the operation unit 22. Alternatively, drug information may be input to the drug packaging device 1 through communication from an external device. The storage unit 61 stores a determination flag indicating whether or not the medicine tends to remain in the contact area in association with the medicine information.

Next, dispensing data is input to the drug packaging device 1 (step S102). The control unit 50 displays a prescription data input screen on the display unit 21. The prescription data includes, for example, the name of one or more drugs to be taken, dosage form (powder/tablet/capsule/liquid/external medicine), administration method, dosage, and the like. Dosage method refers to the number of doses per day, timing of administration, and number of days of administration.Dose refers to the amount of the entire dose (e.g., weight), the amount of the daily dose (weight), and the amount of one dose ( weight) etc. The dispensing data also includes the person taking the drug, the target amount, the measurement result (the measured amount or the amount of deficiency or surplus with respect to the target amount), and identification information for identifying each dispensing data (such as a dispensing data number).

The operator inputs the dispensing data into this input screen using the operation unit 22. The dispensing data input by the operator is stored in the storage section 61 of the control section 50. In addition to the configuration in which the operator manually inputs the dispensing data, the dispensing data may also be input into the drug packaging device 1 through communication from an external information processing device such as a dispensing device control device.

When the input of the dispensing data is completed, a command to start packaging is issued (step S103). The operator uses the operation unit 22 to input a packaging start command to the control unit 50 .

Next, the medicine is measured out from the medicine container 15 (step S104). In the process of step S104, if the necessary drug container 15 has not been introduced into the drug packaging device 1, weighing can be continued by taking the above-mentioned drug container introduction response. Alternatively, instead of supporting the introduction of drug containers, it is also possible to support external metering.

Next, it is determined whether cleaning of the drug path (hopper 35a) after the previous drug packaging is completed (step S105). The determination in step S105 is repeated until the cleaning of the hopper 35a after the previous drug packaging is completed, and in the meantime, the supply of the drug measured in the previous step S104 to the distribution tray 34a and the start of packaging are on standby. . Details of cleaning the hopper 35a will be described later.

When it is determined that the cleaning of the hopper 35a after the previous drug packaging is completed (YES in step S105), the drug is supplied from the container containing the measured drug in step S104 to the distribution tray 34a. (Step S106), and packaging of the medicine in the packaging section 35 is executed (Step S107). After the packaging is completed, the container and the medicine path (hopper 35a) after the medicine has been discharged are cleaned (step S108). Then, the process ends (END).

The details of the cleaning will be explained below. 8 and 9 are flowcharts showing the flow of processing for cleaning the intermediate container 91.

To clean the intermediate container 91, first, it is determined whether the operation of supplying the medicine contained in the intermediate container 91 to the distribution tray 34a has been completed (step S201 in FIG. 8). The determination in step S201 is repeated until the operation of supplying the medicine to the distribution tray 34a is completed.

When it is determined that the supply operation is completed (YES in step S201), the control unit 50 moves the intermediate container 91 from the supply position P9 to the cleaning standby position P10 (step S202). The control unit 50 holds the intermediate container 91 after discharging the medicine at the supply position P9, and sends a control signal to the second transport unit 14b to operate the held intermediate container 91 to move to the cleaning standby position P10. Output to. The second transport unit 14b that has received the control signal transports the intermediate container 91 from the supply position P9 to the cleaning standby position P10.

Subsequently, the intermediate container 91 is moved from the cleaning standby position P10 to the cleaning position P11 (step S203), and the intermediate container 91 is cleaned at the cleaning position P11 (step S204). As described above, cleaning of the intermediate container 91 can be performed by blowing compressed air onto the inner surface of the intermediate container 91, suctioning, wiping with a brush or the like, or a combination thereof.

After cleaning the intermediate container 91, the determination flag is checked for the medicine contained in the intermediate container 91 (step S205). This determination flag indicates whether or not the drug is likely to remain in the contact area, and indicates whether or not the intermediate container 91 needs to be cleaned after the drug is discharged by the drug discharging section 32. Based on the confirmation result of the determination flag, it is determined whether or not the intermediate container 91 requires cleaning (step S206).

If it is determined that the medicine contained in the intermediate container 91 is a medicine that does not require cleaning of the intermediate container 91 (NO in step S206), the inner surface of the intermediate container 91 has been sufficiently cleaned by the cleaning process in the previous step S204. considered to be cleaned. In that case, the control unit 50 moves the intermediate container 91 cleaned by the cleaning unit 38 to the first standby position P1 (step S207). The control unit 50 controls the transport unit 14 to move the intermediate container 91 from the cleaning position P11 to the cleaning standby position P10, and further to move the intermediate container 91 from the cleaning standby position P10 to the first standby position P1. When the movement of the intermediate container 91 to the first standby position P1 is completed, the process ends (END).

If it is determined that the medicine contained in the intermediate container 91 is a medicine that requires cleaning of the intermediate container 91 (YES in step S206), then the intermediate container 91 is imaged (step S208). The resulting image is displayed on the display unit 21 (step S209). The control unit 50 outputs a control signal to the imaging device 56 attached to the cleaning unit 38 to image the inner surface of the intermediate container 91 at the cleaning position P11. The imaging device 56 that has received the control signal executes imaging. Specifically, the imaging device 56 images the inner surface of the storage section 91a and the inner surface of the discharge path section 91b shown in FIG. 4. The imaging device 56 transmits the captured image to the control unit 50. The control unit 50 that has received the image causes the display unit 21 to display the received image.

FIG. 10 is a diagram showing the display unit 21 that displays a captured image of the inner surface of the intermediate container 91. The display section 21 shown in FIG. 10 displays a leading edge image 201 that is an image taken by the imaging device 56 of the ejection path section 91b of the intermediate container 91, and a center image 202 that is an image taken of the storage section 91a. . The operator using the medicine packaging device 1 looks at the captured image shown in FIG. 10 and determines whether additional cleaning of the intermediate container 91 is necessary (step S210).

Even when it is determined that the medicine contained in the intermediate container 91 is not a medicine that tends to remain in the contact area and does not require cleaning of the intermediate container 91 after being discharged from the intermediate container 91, the intermediate container 91 Alternatively, the image may be taken. In this case, the captured image is not displayed on the display unit 21. The imaging device 56 transmits the captured image to the control unit 50. The control unit 50 that has received the image stores the received image so that it can be recalled as needed.

FIG. 11 is a diagram showing the display section 21 that displays a selection screen for additional cleaning of the intermediate container 91. When the operator operates the operation unit 22 while the display unit 21 is displaying the screen shown in FIG. 10, the selection screen 210 shown in FIG. 11 is displayed. When the operator determines that additional cleaning of the intermediate container 91 is necessary, the operator operates the selection unit 211. When the operator determines that additional cleaning of the intermediate container 91 is not necessary, the operator operates the selection unit 212.

The selection units 211 and 212 correspond to input units in the embodiment that receive input regarding whether cleaning of the intermediate container 91 is necessary. The operator who visually checks the screen shown in FIG. 10 and determines whether additional cleaning of the intermediate container 91 is necessary can decide whether additional cleaning of the intermediate container 91 is necessary or not by operating one of the selection sections 211 and 212. The results can be input to the control unit 50.

If it is determined that additional cleaning of the intermediate container 91 is not necessary (NO in step S210), the intermediate container 91 is moved to the first standby position P1 in step S207, and the process ends (END).

If it is determined that additional cleaning of the intermediate container 91 is necessary (YES in step S210), the intermediate container 91 is moved to the first removal position P5 (step S211). The control unit 50 controls the transport unit 14 to move the intermediate container 91 from the cleaning position P11 to the cleaning standby position P10, and further to move the intermediate container 91 from the cleaning standby position P10 to the first take-out position P5.

The operator takes out the intermediate container 91 transported to the first take-out position P5 to the outside of the medicine packaging device 1 and manually performs additional cleaning. This additional cleaning may be any type of cleaning such as suction, blowing with compressed air, wiping with a brush or the like, washing with water, or a combination thereof.

The control unit 50 determines whether additional cleaning has been completed (step S212). If it is determined that the additional cleaning has not been completed (NO in step S212), the determination in step S212 is repeated. When the control unit 50 receives the input from the operator, it is determined that the additional cleaning has been completed.

If it is determined that the additional cleaning has been completed (YES in step S212), the intermediate container 91 is moved to the first standby position (step S213). The control unit 50 controls the transport unit 14 to move the intermediate container 91 after additional cleaning from the first take-out position P5 to the first standby position P1. When the movement of the intermediate container 91 to the first standby position P1 is completed, the process ends (END).

FIG. 12 is a flowchart showing the flow of processing for cleaning the hopper 35a. To clean the hopper 35a, first, it is determined whether the packaging operation is completed (step S301). The determination in step S301 is repeated until the packaging operation is completed.

When it is determined that the packaging operation is completed (YES in step S301), cleaning of the inner surface of the hopper 35a is performed (step S302). Cleaning may be performed by any means such as, for example, blowing compressed air on the inner surface of the hopper 35a, suctioning, wiping with a brush or the like, or a combination thereof. By cleaning, the chemicals remaining on the inner surface of the hopper 35a are removed.

After cleaning the hopper 35a, the determination flag is checked for the medicine packaged in the previous process (step S303). This determination flag indicates whether or not the drug tends to remain in the contact area, and indicates whether or not it is necessary to clean the drug path (hopper 35a) through which the drug passed after packaging the drug. It is. Based on the confirmation result of the determination flag, it is determined whether the medicine requires cleaning of the medicine path (hopper 35a) (step S304).

If it is determined that the packaged medicine is a medicine that does not require cleaning of the medicine path (NO in step S304), it is determined that the inner surface of the hopper 35a has been sufficiently cleaned by the cleaning process in step S302. The process is then terminated (END).

If it is determined that the packaged medicine requires cleaning of the medicine path (YES in step S304), then the inside of the hopper 35a is imaged (step S305), and the taken image is displayed. section 21 (step S306). The control unit 50 outputs a control signal for imaging the inner surface of the hopper 35a to an imaging device 54 arranged above the hopper 35a. The imaging device 54 that has received the control signal executes imaging. The imaging device 54 transmits the captured image to the control unit 50. The control unit 50 that has received the image causes the display unit 21 to display the received image.

Even when it is determined that the packaged medicine is not a medicine that tends to remain in the contact area and does not require cleaning of the medicine route after packaging, the medicine route may be imaged. In this case, the captured image is not displayed on the display unit 21. The imaging device 54 transmits the captured image to the control unit 50. The control unit 50 that has received the image stores the received image so that it can be recalled as needed.

FIG. 13 is a diagram showing the display section 21 that displays a captured image of the inner surface of the hopper 35a. The display unit 21 shown in FIG. 13 displays a hopper inner surface image 220, which is an image captured by the imaging device 54 of the inner surface of the hopper 35a. The operator using the drug packaging device 1 looks at the captured image shown in FIG. 13 and determines whether additional cleaning of the hopper 35a is necessary.

FIG. 14 is a diagram showing the display section 21 that displays a selection screen for additional cleaning of the hopper 35a. When the operator operates the operating section 22 while the display section 21 is displaying the screen shown in FIG. 13, a selection screen 230 shown in FIG. 14 is displayed. When the operator determines that additional cleaning of the hopper 35a is necessary, the operator operates the selection unit 231. When the operator determines that additional cleaning of the hopper 35a is not necessary, the operator operates the selection unit 232.

The selection units 231 and 232 correspond to input units in the embodiment that receive input regarding whether cleaning of the hopper 35a is necessary. The operator who has determined whether additional cleaning of the hopper 35a is necessary by visually checking the screen shown in FIG. It can be input to the control unit 50.

If it is determined that additional cleaning of the hopper 35a is not necessary (NO in step S307), the process is ended (END).

If it is determined that additional cleaning of the hopper 35a is necessary (YES in step S307), additional cleaning of the hopper 35a is performed (step S308). Details of the additional cleaning of the hopper 35a will be described later.

The control unit 50 determines whether additional cleaning has been completed (step S309). If it is determined that the additional cleaning has not been completed (NO in step S309), the determination in step S309 is repeated. It is determined that the additional cleaning has been completed when the control unit 50 receives an input from the operator or when the control unit 50 finishes a series of additional cleaning processes. When the additional cleaning of the hopper 35a is completed, the process ends (END).

FIG. 15 is a flowchart showing a first example of the process of additionally cleaning the hopper 35a. In the additional cleaning of the hopper 35a shown in FIG. 15, the hopper 35a is first unlocked (step S311).

The operator who has determined that additional cleaning of the hopper 35a is necessary in step S307 of FIG. 12 controls the determination result that additional cleaning of the hopper 35a is necessary by operating the selection section 231 displayed on the display section 21. The information is input to the section 50. Upon receiving this input, the control unit 50 outputs a control signal instructing the locking mechanism 52 (FIGS. 2 and 3) to unlock the hopper 35a. Upon receiving the control signal, the locking mechanism 52 unlocks the hopper 35a, making it possible to remove the hopper 35a from the medicine packaging device 1.

Subsequently, the hopper 35a is removed from the drug packaging device 1 (step S312). The removed hopper 35a is cleaned (step S313). The cleaned hopper 35a is reattached to the drug packaging device 1 (step S314). The removal, additional cleaning, and reinstallation of these hoppers 35a are performed manually by an operator using the drug packaging device 1. The additional cleaning in step S313 may be any type of cleaning such as suction, blowing compressed air, wiping with a brush, washing with water, or a combination thereof.

After the reinstallation in step S314, the control unit 50 receives the operator's input, and thereby the control unit 50 determines that the hopper 35a that has undergone additional cleaning has been installed. After that, the control unit 50 relocks the hopper 35a (step S315). The control unit 50 outputs a control signal instructing the locking mechanism 52 to lock the hopper 35a. Upon receiving the control signal, the locking mechanism 52 locks the hopper 35a so that the hopper 35a cannot be removed from the medicine packaging device 1. In this way, the additional cleaning of the hopper 35a is completed (END).

In the first example of the process of additionally cleaning the hopper 35a, the next supply of the medicine to the distribution tray 34a is waited until the cleaning of the hopper 35a after the previous medicine packaging is completed.

FIG. 16 is a flowchart showing a second example of the process for additionally cleaning the hopper 35a. In the additional cleaning of the hopper 35a shown in FIG. 16, data on the cleaning material is first input to the medicine packaging device 1 (step S321). The control unit 50 displays an input screen for cleaning material data on the display unit 21. The cleaning material data includes, for example, the type of cleaning material, the amount of cleaning material to be packaged, the number of packages, the number of empty packages, the packaging speed, the length (paper width) of the packaging material 40 per package, and the supply of cleaning material. This includes the distribution parts (left side, right side, both left and right sides), various conditions for supplying the cleaning material to the distribution pan 34a, etc. The operator inputs cleaning material data into this input screen using the operation unit 22. Instead of the configuration in which the operator manually inputs the cleaning material data, the cleaning material data may be inputted into the drug packaging device 1 from the outside via communication.

When the input of the cleaning material data is completed, a cleaning start command is issued (step S322). The operator uses the operating section 22 to input a cleaning start command to the control section 50 .

Next, the cleaning material is measured from the medicine container 15 (step S323). The control unit 50 controls the weighing unit 30 to take out a required amount of cleaning material from the medicine container 15 containing the cleaning material into the intermediate container 91. Instead of measuring the cleaning material from the drug container 15, the necessary amount of cleaning material is stored in the external drug container 92 outside the drug packaging device 1, and the external drug container 92 is introduced into the drug packaging device 1. You can.

The cleaning agent may be lactose. The cleaning agent may be the type of lactose used as an excipient, or it may be other types of lactose. Alternatively, the cleaning material may be other types of powdered compounds such as starch, sodium bicarbonate, etc.

Subsequently, the cleaning material is supplied from the containers accommodating the cleaning material (intermediate container 91, external drug container 92) to the distribution plate 34a (step S324), and the cleaning material is packaged in the packaging section 35 (step S324). Step S325). When the cleaning material passes through the same route as the route through which the medicine is packaged, the cleaning material collides with the residual medicine adhering to the inner surface of the route (distribution tray 34a, hopper 35a) and is peeled off from the inner surface. As a result, the path is cleaned with the cleaning material. When the packaging of the cleaning material is completed, the additional cleaning of the hopper 35a ends (END).

In the second example of the process of additionally cleaning the hopper 35a, when the cleaning material is supplied from the medicine container 15 containing the cleaning material to the distribution tray 34a, the hopper 35a is cleaned after the previous medicine distribution. Measurement of the medicine from the medicine container 15 is on standby until the completion of the measurement.
