As described above, the medicine packaging device 400 includes the control device unit 460.

Hereinafter, the operation of the first drug supply device 10 according to an embodiment of the present invention will be described. First, the operation of the medicine supply module 100, which is a medicine supply section, will be explained.

The medicine supplied from the medicine supply hole 127 to the inside of the lid member 120 is received at a medicine receiving position on the slope 110s, and is supported by the first peripheral wall part 121. The first motor 270 drives each of the first rotating section 111 and the second rotating section 112.

By driving the first rotating section 111, the drug supported by the first peripheral wall section 121 is conveyed along the first peripheral wall section 121. The medicine supported by the first peripheral wall 121 is aligned along the first peripheral wall 121 while being conveyed along the first peripheral wall 121 .

The medicine supported by the first peripheral wall part 121 sequentially moves outward in the radial direction about the axis 1 while descending along the first inclined wall part 124, starting from the medicine located on the leading side in the rotation direction 2. By doing so, it is supported by the second peripheral wall portion 122.

The medicine descending along the first inclined wall part 124 is accelerated by gravity, and therefore moves at a higher speed than the medicine being conveyed along the first peripheral wall part 121. Thereby, the distance between the drug that has descended along the first inclined wall portion 124 and the drug that has not descended along the first inclined wall portion 124 becomes wider.

By driving the first rotating part 111, the drug supported by the second peripheral wall part 122 is conveyed along the second peripheral wall part 122. The medicine supported by the second peripheral wall part 122 is moved outward in the radial direction while descending along the second inclined wall part 125, starting from the medicine located on the leading side in the rotational direction 2. It is supported by the peripheral wall portion 123.

The medicine descending along the second inclined wall part 125 is accelerated by gravity, and therefore moves at a higher speed than the medicine being conveyed along the second peripheral wall part 122. Thereby, the distance between the drug that has descended along the second inclined wall portion 125 and the drug that has not descended along the second inclined wall portion 125 becomes wider.

By driving the second rotating section 112, the drug supported by the third peripheral wall section 123 is conveyed along the third peripheral wall section 123. Since the rotational speed of the second rotating section 112 is higher than the rotational speed of the first rotating section 111, the distance between the medicine supported by the third peripheral wall part 123 and the medicine supported by the second peripheral wall part 122 is small. It becomes wider.

The medicines supported by the third peripheral wall part 123 are supported by the standing wall part 132 in order from the medicine located on the leading side in the rotation direction 2. By driving the second rotating section 112, the medicine supported by the standing wall section 132 is conveyed along the standing wall section 132.

In a state where the medicine stopping part 142 is close to the slope 110s, the medicine conveyed along the vertical wall part 132 is prevented from moving to the discharge part 131. Therefore, the second motor 271 rotates the rotation shaft 140s.

By rotating the rotating shaft 140s in one direction, the opening/closing member 140 rotates around the rotating shaft 140s, the discharge section 131 that was blocked by the opening/closing section 141 is opened, and the drug retaining section 142 is opened. Separate from the slope 110s. As a result, among the medicines supported by the standing wall part 132, the medicines located on the leading side in the rotational direction 2 are discharged one by one from the discharge part 131.

At this time, the first sensor 231 detects that the medicine on the slope 110s is discharged from the discharge section 131. The second sensor 232 detects the medicine discharged from the discharge section 131.

After the medicine is discharged from the discharge part 131, the rotation shaft 140s is rotated in the other direction, so that the opening/closing member 140 is rotated around the rotation shaft 140s, and the discharge part 131 is closed by the opening/closing part 141. , the drug stopper 142 approaches the slope 110s.

As a result, the medicine supported by the standing wall part 132 is prevented from moving to the discharge part 131 by the medicine stopping part 142, and is prevented from being discharged from the discharge part 131 by the opening/closing part 141. As described above, the opening/closing section 141 is in the open state when the drug is supplied from the drug supply section, and is in the closed state when the drug is not supplied from the drug supply section.

When the medicine supply section moves relative to the housing 410, the medicine supply section stops and the opening/closing section 141 enters the closed state, and then the medicine supply section starts moving. In this case, it is possible to prevent undesired medicine from being discharged from the discharge part 131 while the medicine supply part is moving.

When restarting the supply of medicine from the medicine supply section, the opening/closing section 141 is brought into an open state and the medicine supply section is restarted. In this case, the medicine can be discharged from the discharge section 131 immediately after the medicine supply section is restarted.

Next, the operation of the drug replenishment section 12 will be explained.
The third motor 272 rotates the pair of rollers 282, thereby rotationally driving the drug storage container 300 around the axis 3.

By rotationally driving the drug storage container 300 around the axis 3, the drug in the drug storage container 300 is conveyed from the bottom 330 side of the drug storage container 300 to the first opening 313 side by the spiral groove 312, and the drug is transferred to the first opening 313 side of the drug storage container 300. It is discharged from the section 313.

The medicine discharged from the first opening 313 passes through the connecting conduit 290 of the base part 200 and is supplied into the medicine supply hole 127 of the lid member 120. The medicines supplied into the medicine supply holes 127 of the lid member 120 are discharged one by one from the discharge part 131 of the medicine supply module 100.

Note that one drug storage container 300 sequentially selected from among the plurality of drug storage containers 300 is attached to the base portion 200 . Each of the plurality of drug storage containers 300 is driven under mutually different driving conditions set based on the identifier 331. The drug supply unit is driven in correspondence with each of the plurality of drug storage containers 300.

Specifically, the types of drugs include general drugs that are small tablets, and special drugs such as capsules, elongated tablets, spherical tablets, or triangular prism-shaped tablets. Each of the plurality of drug storage containers 300 contains a general drug or a special drug. When the drug storage container 300 is attached to the base section 200, the control section 11 to which the detection signal of the identifier 331 from the identification sensor 234 is input is housed inside the drug storage container 300 attached to the base section 200. Determine the type of drug being used. That is, a drug information signal having drug information regarding the shape of the drug, which is included in the detection signal of the identifier 331 from the identification sensor 234, is input to the control unit 11.

Hereinafter, a control flow when the drug packaging device 400 according to an embodiment of the present invention packages drugs according to prescription information will be described.

FIG. 35 is a time chart when the drug packaging device according to one embodiment of the present invention operates according to prescription information. FIG. 36 is a diagram for explaining prescription information and packaging information.

As shown in FIG. 35, prescription information is input to the prescription information receiving device 90. The prescription information includes information such as the type of drug, the time of administration, the number of days of administration, the daily dose, and the dose at each time of administration.

In the example of prescription information shown in FIG. 36, three days' worth of drugs are prescribed in one prescription, the required number of A drugs in one prescription is 9, and the required number of B drugs in one prescription is 6. It is. The required number of drugs A is one each after breakfast, lunch, and dinner. The required number of B drugs is 0 each after breakfast and dinner, and 2 after lunch.

In this embodiment, it is assumed that one piece of packaging information is created based on one piece of prescription information. In this case, one prescription corresponds to one piece of packaging information based on one piece of prescription information.

As another example, multiple pieces of packaging information may be created based on one prescription information. For example, if one prescription information includes three types of drugs, the first package information is created for two of the three drugs, and the second package information is created for the remaining one. may be created. In this case, each of the plurality of pieces of created packaging information corresponds to one prescription here.

As another example, one piece of packaging information may be created based on a part of one piece of prescription information. For example, if one prescription information includes three types of drugs, one package information is created for two of the three drugs, and no package information is created for the remaining one. be. In this case, one piece of created packaging information corresponds to one prescription here.

As shown in FIG. 35, the prescription information receiving device 90 inputs packaging information corresponding to the input prescription information to the operation panel 50. The packaging information includes information for packaging the medicine according to the prescription information.

As shown in FIG. 35, after the packaging information is input from the prescription information reception device 90 to the operation panel 50, selection information for selecting which drug supply device to supply the drug from among the plurality of drug supply devices; Then, a packaging instruction for causing the medicine packaging device 400 to start packaging operation is input from an input unit provided on the operation panel 50.

As shown in FIG. 35, when a packaging instruction is input to the input section of the operation panel 50, packaging information including selection information is input from the operation panel 50 to the main control section 41. The main control unit 41, which has received the packaging information including the selection information, inputs the required number of drugs in one prescription to the control unit 11 of the first drug supply device 10 selected by the selection information. As described above, the packaging information signal having the packaging information of the medicine is input to the control device unit 460 constituted by the control unit 11 and the main control unit 41 of each of the plurality of first medicine supply devices 10. Ru.

Thereafter, the required number of drugs in one package and a supply instruction for starting a supply operation are sequentially input from the main control section 41 to the control section 11 at appropriate timings. When the supply instruction is input, the control unit 11 executes a supply operation for one package. When the feeding operation for one package is completed, a completion notification to that effect is input from the control section 11 to the main control section 41.

When the dispensing and packaging operation for one prescription is completed, a completion notification to that effect is input from the main control unit 41 to the operation panel 50.

FIG. 37 is a flowchart illustrating the operation in the control section of the drug supply device in which the required number of drugs in one prescription is input from the main control section. As shown in FIG. 37, the control unit 11 of the first drug supply device 10 receives the required number of drugs for one prescription from the main control unit 41 and identifies the drug storage container 300 based on the input signal from the identification sensor 234. (Step S11). The control section 11 that has identified the drug storage container 300 causes the drug replenishment section 12 to start replenishing the drug (step S12).

FIG. 38 is a flowchart illustrating the operation of the control unit when replenishing medicine by the medicine replenishment unit. As shown in FIG. 38, the control unit 11 causes the drug replenishment unit 12 to start replenishing the drug (step S12), and then determines whether the number of supplies is less than the required number of drugs for one prescription (step S12). S21).

Specifically, in the example of the packaging information shown in FIG. 36, the control unit 11 of the first drug supply device 10 in which the drug storage container 300 containing drug A is mounted determines the number of drugs to be supplied. It is determined whether the number is less than the required number of 9. The control unit 11 of the first medicine supply device 10 in which the medicine storage container 300 containing the B medicine is mounted determines whether the number of supplies of the B medicine is less than the required number of six.

If the number of supplies is less than the required number of drugs for one prescription, the control unit 11 determines from the drug detection signal whether the drug detection sensor 235, which is a drug detection unit, detects that there is a drug at the drug receiving position. (Step S22).

The control unit 11 stops the third motor 272, which is a replenishment motor, when the drug detection sensor 235 is in the first detection state in which it detects that there is a drug at the drug receiving position (step S23). That is, the control section 11 stops the drug replenishment section 12 from replenishing the drug when the drug detection section is in the first detection state. After this, the control unit 11 returns to step S21.

When the drug detection sensor 235 is in the second detection state in which it detects that there is no drug at the drug receiving position, the control unit 11 rotates the third motor 272 in the normal rotation direction (step S24). That is, the control section 11 causes the drug replenishment section 12 to replenish the drug when the drug detection section is in the second detection state. After this, the control unit 11 returns to step S21.

As described above, the control section 11 receives the drug detection signal from the drug detection section and controls the drug replenishment section 12 in accordance with the drug detection signal.

The control section 11 may be configured to cause the drug replenishment section 12 to replenish the drug after a standby time has elapsed from the time when the drug detection section changed from the first detection state to the second detection state. As described above, the control unit 11 receives a drug information signal containing drug information regarding the shape of the drug, which is included in the detection signal of the identifier 331 from the identification sensor 234. The control unit 11 sets the waiting time according to the drug information.

When the number of supplies is equal to or greater than the required number of drugs for one prescription, the control unit 11 rotates the third motor 272 in the reverse direction (step S25). Thereby, the medicine contained in the medicine storage container 300 can be returned to the inside of the medicine storage container 300 from the first opening 313 side. The control unit 11 stops the third motor 272 after a certain period of time has passed since the third motor 272 is rotated in the reverse direction (step S26).

Note that in a state where the number of supplies is less than the required number of drugs for one prescription, the control section 11 causes the drug replenishment section 12 to replenish the drug when the drug detection section changes from the second detection state to the first detection state. The later of the time when the operation amount of the drug supply unit exceeds the set value from the time when the drug supply unit is stopped and enters the first detection state, and the time when the drug detection unit changes from the first detection state to the second detection state. It may be configured such that the drug replenishment unit 12 restarts replenishment of the drug at this point. In this case, the control unit 11 sets the setting value according to the drug information.

The above operation amount of the drug supply section is the cumulative rotation angle in the rotation direction 2 of the first rotation section 111 in the drug supply section from the time when the first detection state is reached, or the rotation of the first rotation section 111. This is the cumulative drive time in direction 2. Specifically, the set value of the cumulative rotation angle is, for example, 60°. Alternatively, the set value of the cumulative driving time is a driving time required for the cumulative rotation angle to be, for example, 60°.

The above replenishment operation is performed at any time in each of the plurality of first drug supply devices 10 that supply drugs necessary for one prescription. In the present embodiment, the control device unit 460 controls the drug supply unit in the first drug supply device 10 that supplies the drug next to the first drug supply device 10 that is supplying the drug, according to the above-mentioned packaging information. The drug replenishment unit 12 starts replenishing the drug before the first operation starts. Specifically, when the control unit 11 of the first medicine supply device 10 receives the required number of medicines for one prescription from the main control unit 41, it causes the medicine replenishment unit 12 to start replenishing medicines. The control unit 11 of the first medicine supply device 10 causes the medicine replenishment unit 12 to start replenishing the medicine even if no supply instruction is input from the main control unit 41.

Specifically, in the example of the packaging information shown in FIG. 36, the control device unit 460 controls, for example, when the first drug supply device 10 that supplies drug A While supplying a package of drug A, next, in the first drug supply device 10 which supplies three packages of drug B from the first day to the third day after lunch, the first drug supply module 100 Before the first motor 270 starts driving, the drug replenishing section 12 starts replenishing the drug.

More preferably, at the time when the first drug supply device 10 that supplies the next drug starts supplying the drug, the drug replenishing unit 12 has completed the first replenishment and the drug is in the drug receiving position. It has become.

The control device unit 460 sequentially stops the drug replenishment unit 12 from replenishing drugs, starting from the first drug supply device 10 that has finished supplying the required number of drugs for one prescription, according to the packaging information.

Specifically, in the example of the package information shown in FIG. 36, the control device unit 460 finishes supplying the B drug necessary for three packages from the first day to the third day after lunch, and After supplying the required number of B drugs in the prescription, the drug replenishing unit 12 of the first drug supply device 10 stops replenishing the B drugs. Thereafter, the control device unit 460 finishes supplying the A drug required for three packages from the first day to the third day after dinner, and then supplies the first drug after having finished supplying the required number of A drug for one prescription. The replenishment of the A drug by the drug replenishment unit 12 of the supply device 10 is stopped.

FIG. 39 is a flowchart illustrating the operation in the control section of the drug supply device, which receives the required number of drugs in one package and supply instructions from the main control section. As shown in FIG. 39, in the control unit 11 of the first medicine supply device 10, which receives the required number of medicines in one package and the supply instruction from the main control unit 41, the discharge part that was blocked by the opening/closing part 141 131 is opened (step S31).

After opening the discharge section 131, the control section 11 causes the drug supply module 100, which is a drug supply section, to start supplying the drug in one package (S32). After the control unit 11 starts supplying the medicine by the medicine supply module 100 (step S32), the control unit 11 counts the number of medicines supplied from the medicine supply module 100 (step S33). When the number of medicines supplied exceeds the required number of medicines in one package, the supply of medicines by the medicine supply module 100 is terminated (step S34).

Thereafter, the control unit 11 determines whether the number of drugs supplied is equal to or greater than the required number of drugs for one prescription (step S35). When the number of supplies is greater than or equal to the required number of drugs for one prescription, the opening/closing section 141 closes the discharge section 131 (step S36). If the number of supplies is less than the required number of medicines for one prescription, the control unit 11 ends the operation of supplying one package of medicine while maintaining the discharge unit 131 in an open state.

FIG. 40 is a flowchart illustrating the operation of the control unit when a medicine is supplied by the medicine supply unit. As shown in FIG. 40, after the control unit 11 starts supplying the medicine by the medicine supply module 100 (step S32), the control unit 11 determines whether the number of medicines supplied is less than the required number of medicines in one package (step S32). S41).

Specifically, in the example of packaging information shown in FIG. 36, when packaging on the first day after lunch, the first medicine supply device 10 in which the medicine storage container 300 containing medicine A is mounted is used. The control unit 11 determines whether the number of drugs A to be supplied is less than the required number of one. The control unit 11 of the first medicine supply device 10 in which the medicine storage container 300 containing the B medicine is mounted determines whether the number of supplies of the B medicine is less than the required number of two.

When the number of supplies is less than the required number of medicines in one package, the control unit 11 drives the first motor 270, which is a supply motor, in the normal rotation direction, and drives the eccentric motor 273, which is a vibration motor. Step S42). As a result, each of the first rotating section 111 and the second rotating section 112 rotates in the normal rotation direction, and the vibrating section 260 vibrates.

Thereafter, the control unit 11 determines whether or not the first sensor 231, which is the first detection unit, has detected the drug, based on the presence or absence of the first detection signal input from the first sensor 231 (step S43).

When the first sensor 231 detects a drug, the control unit 11 stops the first motor 270 and also stops the eccentric motor 273 (step S44). In this manner, when the first detection signal is input, the control unit 11 temporarily stops the transport of the medicine by the medicine supply unit.

After that, the control unit 11 drives the first motor 270 in the reverse direction by a set amount (step S45). In this manner, when the first detection signal is input, the control unit 11 temporarily reverses the direction in which the medicine is transported by the medicine supply unit.

After driving the first motor 270 in the reverse direction by a set amount, the control unit 11 stops the first motor 270 and returns to step S41.

If the number of supplies is equal to or greater than the required number of drugs in one package, the control unit 11 ends the operation of supplying one package of drugs (step S34).

FIG. 41 is a flowchart illustrating the operation of the control section when counting the drugs supplied by the drug supply section. As shown in FIG. 41, when counting of drugs supplied by the drug supply section (step S33) is started, the control section 11 determines whether or not the first sensor 231, which is the first detection section, has detected the drug. The determination is made based on whether or not the first detection signal is input from the first sensor 231 (step S51).

When the first sensor 231 detects the drug, the control unit 11 turns on the arrival flag (step S52). If the first sensor 231 does not detect the drug, the control unit 11 leaves the arrival flag as is.

Thereafter, the control unit 11 determines whether or not the second sensor 232, which is the second detection unit, has detected the drug, based on the presence or absence of the input of the second detection signal from the second sensor 232 (step S53). In step S53, while the second sensor 232 is detecting the drug, the drug is blocking the optical axis between the light projecting section and the light receiving section that constitute the second sensor 232.

When the second sensor 232 detects the drug in step S53, the control unit 11 determines whether the second sensor 232, which is the second detection unit, does not detect the drug by checking the second detection signal from the second sensor 232. The determination is made based on the presence or absence of input (step S54). In step S54, when the second sensor 232 is not detecting the drug, the drug passes through the optical axis between the light projecting section and the light receiving section that constitute the second sensor 232, and has returned to its original open state. If the second sensor 232 does not detect the drug in step S53, the control unit 11 returns to step S51.

If the second sensor 232 does not detect the drug in step S54, the control unit 11 checks whether the arrival flag is on (step S55). If the second sensor 232 does not detect the drug in step S54, the control unit 11 returns to step S54.

If the second sensor 232 does not detect the drug in step S54 and the arrival flag is on, the control unit 11 adds 1 to the number of supplies (step S56) and turns off the arrival flag ( Step S57).

If the second sensor 232 detects the medicine but the arrival flag is off, the control unit 11 determines that there is an abnormality (step S59) and ends the counting of the medicine. In this way, the control unit 11 determines that there is an abnormality if the second detection signal is input a plurality of times during the input interval during which the first detection signal is input.

After turning off the arrival flag in step S57, the control unit 11 determines whether the number of supplies is equal to or greater than the required number of drugs in one package (step S58). When the number of supplies is equal to or greater than the required number of medicines in one package, the control unit 11 ends the counting of medicines. If the number of supplies is less than the required number of medicines in one package, the control unit 11 returns to step S51.

As described above, the control unit 11 receives the first detection signal from the first sensor 231, controls the drug supply unit according to the first detection signal, and receives the second detection signal from the second sensor 232. and counts the number of drugs supplied from the drug supply section in accordance with the second detection signal.

In this embodiment, when the first detection signal is input, the control section 11 controls the drug supply section according to the drug information. Specifically, if it is determined from the drug information that the drug contained in the drug storage container 300 is a general drug, the general drug is supplied at each rotation amount of the drug storage container 300. Immediately after the drug detection sensor 235 detects that the drug is present at the drug receiving position, the control unit 11 stops the rotation of the drug storage container 300. Thereafter, when the drug is no longer detected by the drug detection sensor 235, the rotation of the drug storage container 300 is restarted. This can prevent oversupply of medicine to the medicine supply section.

If the drug stored in the drug storage container 300 is determined to be a special drug from the drug information, the amount of the special drug discharged to the drug supply unit per rotation of the drug storage container 300 is small. Therefore, the control unit 11 sets the time from when the drug detection sensor 235 detects the presence of the drug at the drug receiving position to when the rotation of the drug storage container 300 is stopped for a typical drug. be longer compared to . Alternatively, the control unit 11 increases the rotational speed of the drug storage container 300 compared to the case of a general drug. Furthermore, the control unit 11 also increases the rotational speed of the rotating body 110 compared to the case of general medicines. By doing so, even in the case of a special drug that is difficult to discharge by rotational driving, the time required for replenishing the drug can be brought closer to that of a general drug, and the drugs can be supplied one by one from the discharge section 131.

In the present embodiment, in the first drug supply device 10, when the drug is discharged from the discharge section 131, each of the rotating body 110 and the vibrating section 260 is temporarily stopped, and the rotating body 110 is temporarily reversed. Then, the medicine discharged from the discharge part 131 is held on the slope 110s.

In the first drug supply device 10, when the drug is discharged from the discharge section 131, the vibrating section 260 is temporarily stopped, the rotating body 110 is temporarily stopped, and then the medicine is discharged from the discharge section 131.
