That is, the pharmacist confirms the doctor's prescription and takes out the medicine bottle containing the prescribed powder from the medicine shelf. Then, the total weight of the specific powder prescribed using a balance such as a balance is measured.

Then, the weighed powder is put into the charging hopper of the powder feeder, and the trough of the powder feeder is vibrated. Further, the distribution tray is rotated at a constant rotation speed.
When the trough vibrates, the powder slowly moved to the tip side and dropped into the groove of the distribution tray.

  When the powder falls on the distribution tray, the rotation of the distribution tray is stopped. Thereafter, the disc of the scraping device is dropped into the groove of the distribution tray. Thereafter, the distribution tray is rotated by a movement amount (angle) according to the number of distribution. Then, the disk is rotated, and the powder for a predetermined angle is scraped out of the distribution tray by the scraper and put into the packaging hopper. The powdered medicine dropped from the packaging hopper is packaged by a packaging device.

  Using the conventional drug dispensing device disclosed in Patent Document 1, it is possible to automate most of the work of packaging powder for each dose, but there remains a process that must be relied on by hand. It is hard to say that this is a device that can fully automate the packaging.

Therefore, the present applicant has developed a medicine dispensing apparatus that automates the work of taking out a medicine bottle containing a desired powder from a medicine shelf and the action of weighing out a predetermined amount of powder from the medicine bottle, and disclosed in Patent Document 2.
The medicine dispensing device disclosed in Patent Document 2 includes a container storage unit that stores a plurality of medicine containers, and a robot (container moving means). There is a container mounting device around the distribution tray. The container mounting device has a function of vibrating the drug container to discharge the powder from the drug container and a function of monitoring the weight of the drug container.
In the medicine dispensing device disclosed in Patent Document 2, a medicine container filled with powder that matches a doctor's prescription is selected from the medicine containers stored in the container storage unit, and the medicine container is taken out by a robot and placed on the container placement device. Put.
The container mounting device is vibrated to discharge the powder from the drug container, monitor the weight of the drug container, and indirectly monitor the weight of the powder discharged from the drug container.
When a predetermined amount of powder is discharged from the drug container, the scraping device is driven to scrape the powder out of the distribution tray and package with the packaging device.

Next, the basic operation of the medicine dispensing apparatus 1 of this embodiment will be described.
The medicine dispensing apparatus 1 of the present embodiment is capable of performing a packaging operation in which information related to prescription is input and the powder is packaged for each dose based on the information.

  That is, the medicine dispensing apparatus 1 is configured to store the medicine container 4 in the container storage section 23, to take out the medicine container 4 from the container storage section 23, to move the taken medicine container 4 to the vicinity of the distribution tray 35, and to the medicine container. 4 is placed on the container placing device 36 to configure the medicine feeder 8, an operation to put a predetermined amount of medicine into the distribution tray 35, and a medicine is supplied from the distribution tray 35 to the medicine packaging device 53 for each dose. The operation and the operation of returning the medicine container 4 to the container storage unit 23 are automatically performed. Each of these operations is controlled by a control unit (not shown).

  As a preparation stage, the medicine container 4 is filled with powdered medicine, and some of them are attached to the container storage part 23 in the container arrangement region 12.

  In the medicine dispensing apparatus 1 of the present embodiment, information related to prescription is input, and the packaging operation is automatically executed based on the information.

That is, in the medicine dispensing apparatus 1 of the present embodiment, the medicine container 4 filled with the necessary powder is selected based on the prescription information, and the necessary medicine container 4 is loaded from the container storage unit 23 into the container by the container moving means 28. It is transported to the placement device 36.
The drug container 4 is held by the electromagnet 41 built in the vibration table 50. The medicine container 4 is integrated with the container placement device 36 by an electromagnet 41 to constitute a medicine feeder 8.
Subsequently, a current having a constant frequency is applied to the vibration means 51 to generate vibration, and the vibration table 50 is vibrated by this vibration.
Further, the distribution tray 35 is rotated before and after the start of vibration.

Before and after the start of vibration, the weight of the drug container 4 is measured by the weight measuring means 52. The weight of the medicine container 4 is obtained by subtracting a certain value from the weight detected by the weight measuring means 52.
The weight of the drug container 4 immediately after installation on the vibration table 50 is stored as the original weight G. The weight of the medicine container 4 is constantly monitored. That is, the current weight of the medicine container 4 is monitored as the current weight g.

  When the vibration table 50 starts to vibrate, the medicine container 4 vibrates. As a result, the powder stored in the medicine container 4 slowly moves toward the opening 72 and is discharged from the opening 72 and dropped.

That the powder is falling is confirmed by a decrease in the weight of the drug container 4. Further, the discharge amount of the powder is detected by the weight measuring means 52. That is, in the present embodiment, the current weight (current weight g) of the drug container 4 is continuously monitored by the weight measuring means 52 even when the powder is falling from the opening 72 of the drug container 4. Then, the original weight G of the drug container 4 immediately after installation on the shaking table 50 is compared with the current weight g, and the amount H (G minus g) of the powder is constantly calculated.
Then, when the total amount H of the powder drops reaches a desired weight, the vibration of the shaking table 50 is stopped.
That is, the current weight g of the medicine container 4 measured by the weight measuring means 52 is reduced by a desired weight with respect to the original weight G before the start of vibration measured by the weight measuring means 52, and a target amount of powder from the medicine feeder 8 is obtained. Is discharged, the vibration of the shaking table 50 is stopped.

Thereafter, the rotation of the distribution tray 35 is stopped. Then, the scraping arm 26 of the scraping device 37 is swung, the tip end side is lowered, the scraping mechanism 27 is lowered, and the disc-shaped scraping plate 57 of the scraping mechanism 27 is placed in the medicine feeding groove of the distribution tray 35. 32.
Further, the distribution tray 35 is rotated by an angle corresponding to the number of distributions, and scraped to the scraping plate 57 (drug collection step). Subsequently, the scraping plate 57 is rotated, the powder is scooped up by the scraping plate 58 and discharged from the distribution tray 35, and the drug is loaded into the drug loading port 39 (scraping process).

  In principle, a single dose of powder is poured into the drug inlet 39 by scooping up and scooping up. However, a single dose of powder is divided into a plurality of scoops and scooping up into the drug inlet 39. In some cases, drugs are used.

The drug charged into the drug charging port 39 falls down the powder charging hopper (FIG. 775), is carried to the drug packaging device 53, and is packaged by the drug packaging device 53.
This operation is sequentially repeated, all the medicines in the distribution tray 35 are discharged, and each medicine is packed by the medicine packaging device 53.
In parallel with this, the container moving means 28 is activated, and the medicine container 4 is returned to the drum member 25 of the container storage unit 23.

Next, the improvements added to the basic configuration will be described.
(1) Dispersion monitoring of powder distribution on distribution tray and detection of capping In medicine dispensing device 1 of the present embodiment, medicine container 4 (medicine feeder 8) is used so that the powder distribution on distribution tray 35 does not vary. The amount of drug discharged per unit time is monitored. As a result, it is possible to detect the removal of the lid of the medicine container 4.
As described above, in the medicine dispensing apparatus 1 of the present embodiment, the current weight (current weight g) of the medicine container 4 is continuously monitored by the weight measuring unit 52 even when the powder falls from the opening 72 of the medicine container 4. ing.

In the medicine dispensing apparatus 1 of the present embodiment, the state of the weight change of the medicine container 4 is also monitored. If there is an irregular weight change during the discharge of powder, a display informing the operation display unit 3 is made.
For example, in a situation where the weight of the drug container 4 is steadily decreasing at a rate of 2 grams per second, the powder from the drug feeder 8 is reduced as in the case where the weight is decreased by 5 grams per second. If there is a sudden change in weight during discharge, a display informing the operation display unit 3 is made.
When the amount of change is extremely large, the vibration of the shaking table 50 is stopped and the discharge of the medicine from the medicine container 4 is interrupted.

Furthermore, a display for selecting whether to continue or stop the distribution work may be displayed on the operation display unit 3.
When the continuation of the distribution work is selected, the powder already distributed on the distribution tray 35 is utilized, and the shortage is additionally supplied from the drug feeder 8 as necessary.
When the distribution stop is selected, the powder already supplied to the distribution tray 35 is collected.

In the medicine dispensing apparatus 1 according to the present embodiment, the display as described above is performed when the discharge amount per unit time of the powder has a certain variation or more.
Specifically, the variation in emission is monitored as follows.
In the medicine dispensing device 1 of the present embodiment, the weight of the medicine container 4 is monitored by the weight measuring means 52 while the shaking table 50 is vibrated to discharge the powder from the medicine container 4, and the medicine container The amount of powder discharged per unit time is detected from the weight change per unit time. A past discharge amount per unit time (a change in the weight of the medicine container 4) is stored as a reference discharge amount for a predetermined time in a memory (not shown).
Then, the current discharge amount of powdered medicine per unit time is compared with the stored reference discharge amount. As a result, when there is a difference exceeding the normal variation range between them, a predetermined display is made on the operation display unit 3.

  In this embodiment, the variation in the discharge amount of the medicine is monitored. As a means for this, a change in the weight of the medicine container 4 is monitored. Therefore, for example, it is possible to detect a case where the lid 73 of the medicine container 4 is detached from the container body 6 due to the vibration of the vibration table 50.

(2) Discharge amount error display As described above, in the medicine dispensing apparatus 1 of the present embodiment, the original weight G of the medicine container 4 immediately after installation on the vibration table 50 is compared with the current weight g, and the powder falls. The amount H (G minus g) is constantly calculated, and the vibration of the shaking table 50 is stopped when the total amount H of the powder drops reaches a desired weight.
In addition to this, in the medicine dispensing device 1 of the present embodiment, the current weight g of the medicine container 4 in a state where the vibration of the vibration table 50 is stopped is re-weighed. Then, the re-weighed current weight g is compared with the original weight G of the drug container 4 immediately after installation, and the fall amount H (G minus g) of the powder actually discharged from the drug container 4 is calculated.
Then, the actual amount of powder fall (discharge amount) H is compared with the target amount (discharge amount comparison function), and the comparison result is displayed on the operation display unit (comparison display means) 3.

The displayed contents indicate whether the actual amount of powder fall (discharge amount) H is an appropriate amount, an excessive amount, or an excessive amount with respect to the target amount.
The display is performed by character display such as “many” or “small” or a graphic symbol. A specific difference may be displayed as a numerical value or a ratio. For example, specific weights such as plus 0.03 grams and minus 0.02 grams are displayed. It may be displayed at a rate such as 2% higher than the target value.
Further, color-coded display may be performed so as to draw the operator's attention. For example, when the difference between the actual fall amount (discharge amount) H and the target amount is too large to be ignored, a warning is displayed in red, and if the difference is within the allowable range, yellow is displayed, and the error range When it can be said, blue display is performed.
It may be accompanied by a warning by sound or light.

The re-weighing of the current weight g of the medicine container 4 described above may be performed by another measuring device. For example, the medicine container 4 may be re-weighed after being transferred from the container mounting device 36 on which the drug container 4 was originally mounted to another container mounting device 36. Alternatively, a reweighing meter may be provided.
Further, a history of weight or the like may be stored in an information storage member 18 such as an RFID attached to the medicine container 4, and the original weight G before discharging the powder may be compared with the current weight g.

(3) Confirmation of the amount of scattered powder when the lid member is opened When the drug container 4 is placed on the container mounting device 36 by the container moving means 28 and the lid member 78 of the drug container 4 is opened, the periphery of the lid member 78 The powder adhering to the splatter may be scattered and fall on the distribution tray 35 in some cases.
If vibration of the vibration table 50 is started from this state and a change in weight from the start of vibration is monitored, the weight of the powder falling on the distribution tray 35 when the lid member 78 is opened is excluded from the measurement target. Therefore, there is a concern that the amount of powder distributed in the distribution dish 35 may be larger than the amount of calculation. There is also a concern that the powder distribution on the distribution tray 35 may vary.

In the present embodiment, by accurately measuring the weight of the medicine container 4, the amount of powder scattered when the lid member 78 of the medicine container 4 is opened and closed can be confirmed.
For example, the lid member 78 of the medicine container 4 is opened, the amount of the medicine in the medicine container 4 immediately before starting the vibration is calculated, and the remaining amount of the medicine stored in the information storage member 18 attached to the medicine container 4 is calculated. Compare. When the difference is large, the operation display unit 3 displays that information.
Furthermore, a display for selecting whether to continue or stop the distribution work may be displayed on the operation display unit 3.
The amount of powder in the medicine container 4 immediately before the start of vibration can be known, for example, by subtracting the weight of the empty medicine container 4 from the weight of the medicine container 4 immediately before the start of vibration.

(4) Overtake of prescription during distribution The medicine dispensing device 1 of the present embodiment includes two distribution trays 35 as described above.
As described above, in the medicine dispensing apparatus 1 of the present embodiment, when information based on the first prescription is input, the medicine container 4 filled with the necessary powder is selected, and the necessary medicine container by the container moving means 28 is selected. 4 is conveyed from the container storage part 23 to the container mounting device 36, and the powdered medicine is supplied to the distribution tray 35R.
When information about another prescription (second prescription) is newly input while powder is being supplied to one distribution tray 35R, the medicine container 4 filled with the necessary powder is selected, and the other Powder is supplied to the distribution tray 35L.

When the supply of powder to each distribution tray 35R, 35L is completed, the rotation of the distribution trays 35R, 35L is stopped, the powder is scooped up by the scraping mechanism 27, and the drug is loaded into the drug inlet 39.
Here, in the present embodiment, although two distribution trays 35 are provided, there is only one medicine inlet 39 and medicine packaging device 53. Therefore, it is necessary to determine in advance the order in which powders are charged into the drug insertion port 39.
The following plan A and plan B can be considered as a method of determining the priority order.
In the present embodiment, either the A plan or the B plan can be selected.
Proposal A: Method in accordance with the order in which prescriptions are input Proposal B: Method in which the supply of powder to the distribution tray 35 is completed in order

For example, the second prescription is input after the first prescription, but the powder supply to the dispenser 35L based on the second prescription is more than the one based on the first prescription. Is assumed to be completed first.
When the plan A is selected, when the powder supply to the distribution tray (second distribution tray) 35L based on the second prescription is finished, the operation is temporarily stopped in this state, and the distribution tray (first distribution) based on the first prescription is selected. The tray waits for the powder supply to the 35R to end, and further waits for all the powder in the distribution tray (first distribution tray) 35R to be completely charged into the drug inlet 39. Then, after all of the powder in the distribution tray (first distribution tray) 35R has been charged into the drug inlet 39, the powder in the distribution tray (second distribution tray) 35L based on the second prescription is supplied to the drug inlet 39. Fill and package.

On the other hand, if the plan B is selected, the powder in the distribution tray (second distribution tray) 35L based on the second prescription in which the powder has been previously charged is charged into the drug inlet 39 and packaged.
That is, according to the plan B, the powders on the distribution tray 35 are put into the drug packaging device 53 in the order in which the powders are supplied from the drug feeder 8 to the distribution tray 35.
According to the plan B, the waiting time for packing is small, and the number of packing processes per day can be increased.

(5) Response when the container moving means fails In the drug dispensing device 1 of the present embodiment, as described above, the drug container 4 filled with the necessary powder is selected based on the prescription information, and the container is moved. The necessary medicine container 4 is transported from the container storage unit 23 to the container mounting device 36 by the means 28.
In the medicine dispensing device 1 according to the present embodiment, if any trouble occurs in the container moving means 28, the fact is displayed on the operation display unit 3, and the container moving means 28 stops to ensure safety. Under normal operation, it will not move.

In the medicine dispensing apparatus 1 according to the present embodiment, even when the container moving means 28 has stopped functioning, the medicine container 4 can be attached to the container placement device 36 by the user's hand and distributed. .
For example, the medicine dispensing apparatus 1 has a front door 34 as shown in FIG. The user may manually open the front door 34, insert the medicine container 4 into the medicine dispensing apparatus 1 from the outside, and attach the medicine container 4 to the container placement apparatus 36.
Further, as shown in FIG. 1, the front door 34 has a small door 33, so that the medicine container 4 may be inserted from the small door 33 and attached to the container mounting device 36.

In order to improve workability and safety, it is also recommended that the front door 34 or the small door 33 be an automatic door that opens and closes by power.
When the drug container is mounted on the container mounting device 36 by the user's hand, an open type drug container 60 as shown in FIG. 6 may be used.

(6) Control for early discharge at an early stage In the present embodiment, the vibration frequency and amplitude of the vibration table 50 can be changed.
The problem is that the discharge amount is not stable at the initial discharge of powder, and the behavior in the drug container 4 varies depending on the type of powder. Therefore, the vibration pattern of the shaking table 50 of the container mounting device 36 is changed to the drug type, discharge timing, It can be changed according to the discharge amount.
In the present embodiment, the vibration is strengthened until the medicine reaches the opening 72 at the distal end of the medicine container 4, and when the medicine reaches the opening 72 at the distal end and the powder starts to fall, it shifts to normal vibration. To do.
In this embodiment, it has the discharge | emission monitoring sensor which optically confirms whether the powder started to fall.
In this embodiment, it has the monitoring camera 40 which monitors that the powder medicine is discharged | emitted from the chemical | medical agent container 4, and the said monitoring camera 40 is utilized as a discharge | emission monitoring sensor.

In the present embodiment, the vibration table 50 vibrates more strongly than in a normal case until the monitoring camera 40 captures the fall of the powder from the medicine container 4.
In the present embodiment, the initial vibration intensity from the start of vibration until the discharge monitoring sensor detects the initial discharge of the medicine is made stronger than the normal vibration intensity after detecting the initial discharge, reaches the opening 72 and starts to fall. And it shifts to normal vibration.
As a result, the moving speed of the powder in the drug container 4 is increased, and the opening (drug discharge part) 72 is reached in a short time.

(7) Slow Stop of Dispensing Dish In this embodiment, after discharging the target amount of powder from the medicine container 4, the dispensing dish 35 is decelerated, and the dispensing dish is slowly stopped over a certain period of time.
That is, after the target amount of powder is completely discharged, the distribution tray 35 is not braked suddenly, but the number of rotations of the motor that rotates the distribution tray 35 is gradually decreased to stop.

  It is recommended that the time required for stopping is 2 seconds or more, and more recommended is 3 seconds or more.

  According to this method, the inertia applied to the powder when stopping the distribution tray 35 is reduced. Therefore, when the distribution tray 35 is stopped, the powder in the distribution tray 35 does not collapse, and the powder remains in a uniformly distributed state in the distribution tray 35.

(8) Detection of remaining capacity of dust collection bag of dust collection means In this embodiment, the dust collection means as shown in FIG. 7 is provided. The dust collecting means collects the dust in the dust collection bag 43 by generating a negative pressure and sucking the dust together with the air, as is well known. The dust collecting means is connected to the hopper 75 of the medicine inlet 39 as shown in FIG. It is also connected to the cleaning device 38 described above. Furthermore, it has a manual nozzle (not shown), and each part can be manually cleaned as necessary.
The means for generating the negative pressure is a vacuum pump 76, specifically a centrifugal blower such as a blower, which is rotated by a motor. A dust collection bag 43 for collecting dust is incorporated.
In the present embodiment, the rotational speed of the motor of the blower is detected, and when the rotational speed of the motor exceeds a certain level, it is determined that the remaining capacity of the dust collection bag 43 has decreased, and the replacement of the dust collection bag 43 is urged. The display is displayed on the operation display unit 3.

  Alternatively, the current supplied to the motor is detected, and when the current falls below a certain level, it is determined that the remaining capacity of the dust bag 43 has decreased, and the dust bag 43 is replaced. A display prompting the user may be displayed on the operation display unit 3.

The reason is that if the remaining capacity of the dust bag 43 is reduced and clogged, the amount of air moved by the blower is reduced and the work of the motor is reduced. As a result, the rotational speed of the motor tends to increase. The current value tends to decrease.
Therefore, by monitoring the rotation speed and current of the motor, the remaining capacity of the dust bag 43 can be estimated, and the arrival of the replacement time can be known.

(9) Expiration date management of medicine The medicine container 4 employed in the present embodiment has an information storage member 18 such as RFID attached thereto, and information on medicines stored in the medicine container 4 is stored in the information storage member 18. Yes.
For example, a solid medicine such as a tablet may be pulverized and taken as a powder. Then, the pulverized medicine can be stored in the medicine container 4 and packaged by the medicine dispensing apparatus 1 of the present embodiment.
Here, although there is no rule about the expiration date of the medicine which pulverized the solid medicine and reprocessed into powder form, it should be consumed earlier than the medicine in the solid state.
Therefore, in this embodiment, the information storage member 18 stores information related to the date when the solid agent was crushed and the original expiration date.
Or the information relevant to the time limit which should use the chemical | medical agent accommodated in the said chemical | medical agent container 4 is memorize | stored in the separate database.
When using the medicine stored in the medicine container 4, a display for prompting attention regarding the expiration date is displayed on the operation display unit 3.

For example, regarding powdered powder obtained by pulverizing a solid agent, the expiration date is uniquely determined in the pharmacy separately from the expiration date of the solid agent. For example, the upper limit of storage days is determined. If the container storage unit 23 has a medicine container 4 containing a powder that exceeds the above storage days or a powder that has approached the storage days, calculated from the date and time when the solid agent is crushed, Regardless of this, the fact is displayed on the operation display unit 3.
Moreover, when starting the medicine dispensing apparatus 1 as in the start of work or when a corresponding prescription is issued and inputted, it is displayed on the operation display unit 3.
In addition, a message is displayed on the operation display unit 3 so that the pharmacist can confirm and determine whether or not to use the powder.

(10) Drug Container Temporary Placement Unit In the drug dispensing device 1 of this embodiment, drug container temporary placement units 80 and 81 are provided in the housing 10 as shown in FIG.
One drug container temporary placement portion 80 is provided on the door portion 16 as shown in FIG. 8, and projects out of the housing 10 by opening the door portion 16. When the door portion 16 is closed, the medicine container temporary placement portion 80 is accommodated in the housing 10.
Another drug container temporary placement portion 81 is installed on the inner wall of the housing 10.
The medicine container temporary placement portions 80 and 81 are configured by a placement table 82, an engagement lever 83, and a holding member 85.
The mounting table 82 includes a backrest portion 86 and a pedestal portion 87.
The mounting table 82 is provided with weight measuring means (not shown) for measuring the weight of the medicine container 4.

  A scraping member 90 (cleaning unit) is provided at a position directly above the temporary container portions 80 and 81. The scraping member 90 has a concave portion 91 (container contact portion) whose cross-sectional shape follows the shape of the container body 6. A suction port 92 is opened inside the recess 91 (container contact portion), and the suction port 92 is connected to a suction device (not shown).

A lid confirmation sensor 93 is provided in the medicine container temporary placement portion 80 provided in the door portion 16. The medicine container temporary placement part 80 provided in the door part 16 is used for the purpose of temporarily placing the medicine container 4 when the medicine container 4 is carried into the housing 10 from the outside.
The container body 6 is installed in the medicine container temporary placement unit 80, and the initial weight of the container body 6 is detected. Further, the lid confirmation sensor 93 can detect whether or not the lid 73 is correctly attached to the container body 6.

The medicine container temporary placement portion 81 attached to the inner wall of the housing 10 is used for checking the weight of the medicine container 4 before or after discharging the powder from the medicine container 4.
As described above, the medicine container 4 is attached to the medicine container temporary placement section 81 using a human hand or the hand portion 47 of the container moving means 28. The medicine container temporary placement using the container moving means 28 is performed. When attaching to the part 81, it is desirable to wipe the side surface of the medicine container 4 with the scraping member 90 and then attach it to the container placement device 36.

In addition, before returning the drug container 4 after discharging the powder to the container storage unit 23, the drug container 4 is installed in the drug container temporary storage unit 81 to perform weight measurement and cleaning.
As shown in FIGS. 9 and 10, the cleaning operation is performed by pressing the side surface of the drug container 4 against the recess 91 (container contact portion) of the member 90 by the container moving means 28 and sliding the drug container 4 downward or upward. . At the same time, a suction device (not shown) is activated.
At this time, as shown in the figure, it is recommended that the lid member 78 be opened. By cleaning the lid member 78 in an open state, the powdered residue remaining on the back surface (the surface facing the inside of the medicine container 4) of the lid member 78 can be removed.

(11) Drug Container Movement Route In the drug dispensing device 1 of the present embodiment, the drug container 4 is moved by the container moving means 28. For example, the necessary medicine container 4 is transported from the container storage unit 23 to the container mounting device 36 by the container moving means 28.
Here, the movement path of the medicine container 4 is arbitrary.
As one measure, for example, it is conceivable to move linearly from the initial position to the target position. This measure is recommended because it takes less time to move.

As another measure, there is a method of making a detour on the distribution tray 35 and moving it to the destination.
For example, when the medicine container 4 is linearly moved from the container storage unit 23 toward the container placement device 36, the medicine container 4 often passes over the distribution tray 35. Here, if powder is adhered to the outer surface of the drug container 4 or powder is adhered to the movable part of the lid member 78, the powder is distributed when the drug container 4 passes over the distribution plate 35. There is a concern of falling on the plate 35. As a measure for solving this problem, a method of making a detour on the distribution tray 35 and moving it to the destination can be considered.
In the present embodiment, a method of moving around the distribution tray 35 to the destination is adopted.

FIG. 11 is an explanatory view showing the movement trajectory of the container moving means 28, in which the medicine container 4 is installed in any one of the container placement devices 36a, 36b, 36c belonging to the right distribution tray 35R side, and then returned. The passing trajectory of the medicine container 4 at the time is shown.
In the present embodiment, the medicine container 4 is moved over the container placement devices 36a, 36b, and 36c, and is placed on any of the container placement devices 36a, 36b, and 36c, so that the powder is distributed in the distribution tray 35. Prevents falling down. The same applies to the case where the medicine container 4 is returned from the container placement devices 36a, 36b, and 36c to the container storage unit 23, and is transported by detouring on the distribution tray 35.

(12) Ventilation in the housing In the medicine dispensing device 1 of the present embodiment, the housing 10 is provided with a fan (not shown). In principle, the fan is always operated except when the front door 34 is open and when the powder is supplied to the distribution tray 35 or divided.
However, if the difference between the detected temperature of the temperature detecting means (not shown) in the housing 10 and the detected value of the outside air temperature detecting means (not shown) is small, the fan is stopped.
Also when the heater for adjusting the temperature in the housing 10 is operated in an energy saving manner. Stop the fan.
Stopping the fan can be expected to reduce noise and reduce power consumption.

(13) Standby position of container moving means When the door portion 16 or the small door 33 of the housing 10 is opened, the energization to the container moving means 28 is stopped and does not move by a normal operation to ensure safety. It becomes a state.
When the door 16 or the small door 33 is closed, the container moving means 28 is turned on and the container moving means 28 returns to the standby position. That is, the container moving means 28 performs an origin confirmation operation.
Here, in the medicine dispensing device 1 of the present embodiment, there are a plurality of standby positions (origins). In this embodiment, when the door part 16 etc. are closed and the container moving means 28 returns to a standby position, it moves to the standby position near from a present position.
Therefore, the medicine dispensing apparatus 1 of the present embodiment has a short time required for the initialization operation.

(14) Residual medicine detection sensor In the medicine dispensing device 1 of the present embodiment, a residual medicine detection sensor 48 is provided above the distribution tray 35 as shown in FIG. The remaining medicine detection sensor 48 is a sensor for confirming that no powder remains in the cleaned distribution tray 35.
The remaining medicine detection sensor 48 is an optical sensor, and is a unit in which a light projecting unit and a light receiving unit are integrated.
In the remaining medicine detection sensor 48, the distribution tray 35 is irradiated with light from the light projecting unit. When there is no dirt or residual medicine in the distribution tray 35, the light irradiated from the light projecting unit is regularly reflected on the surface of the distribution plate 35 and does not return to the light receiving unit.
On the other hand, if there is dirt or residual medicine on the distribution tray 35, the light irradiated from the light projecting part strikes the residual medicine or the like and diffusely reflects, and part of the light enters the light receiving part of the residual medicine detection sensor 48.
Therefore, it is possible to detect whether there is dirt or residual medicine in the irradiation unit.

  In the present embodiment, the light projecting portion and the light receiving portion of the remaining medicine detection sensor 48 are covered with the filter member 56. The filter member 56 is specifically a purple resin plate, and more specifically a purple acrylic plate.

By providing the purple filter member 56, disturbance light can be shielded and chattering of the remaining medicine detection sensor 48 and erroneous detection can be prevented.
That is, the housing 10 of the medicine dispensing device 1 is transparent and has translucency. Therefore, illumination light such as LEDs installed indoors passes through the housing 10 and enters the housing 10, and diffusely reflects inside and enters the light receiving portion of the residual drug detection sensor 48, thereby causing chattering and erroneous detection. May occur.
The purple acrylic plate can efficiently block light having a wavelength emitted from the LED illumination or the like, and can prevent light emitted from the LED illumination or the like from entering the residual drug detection sensor 48.

(15) Scattering of powder (divided scraping)
In the medicine dispensing apparatus 1 of this embodiment, the medicine for one dose can be divided into a plurality of scooping (scraping steps) and the medicine can be introduced into the medicine inlet 39.
In this embodiment, a special operation can be performed at that time.

For example, it is possible to squeeze the powdered medicine into three times and put it into the medicine inlet 39. Specifically, the drug collection step is performed, and then the scraping step is performed. This is repeated three times, and a single dose of powder is loaded into the drug inlet 39.
Here, in the present embodiment, the amount of powder to be collected at one time is not the same in the drug collecting step that is carried out in three steps, and the amount is set to be smaller as the subsequent steps are performed. In other words, the amount of movement (rotation angle) in the rotation direction of the distribution tray 35 is smaller as the subsequent steps are performed.
Further, in this embodiment, prior to the first drug collection step, the scraping plate 57 of the scraping mechanism 27 is placed in the medicine charging groove 32 of the distribution tray 35, and the scraping plate is rotated without rotating the distribution tray 35. An initial charging step of rotating 58 and scooping up the powder in the vicinity of the scraping plate 58 and charging it into the drug inlet 39 is performed.

Hereinafter, a description will be given with reference to FIGS. 13 and 14.
In this embodiment, the angle of the distribution tray 35 is pulse-controlled with an encoder.
Assuming that the amount of movement in the rotation direction corresponding to the amount of powder for one dose is 5000 pulses, for example, as shown in FIG. 13A, 3500 pulses are collected, 900 pulses are collected, and 600 pulses are collected. Collect the medicines separately and discharge each one.

Explaining the process step by step, the scraping plate 57 of the scraping mechanism 27 is distributed in a state where the target amount of powder is discharged from the drug feeder 8 and the powder is evenly distributed on the distribution tray 35 as shown in FIG. It puts in the medicine insertion groove 32 of the dish 35.
Then, as shown in FIG. 13C, without rotating the distribution tray 35, the scraping plate 58 is rotated to scoop up the powder in the vicinity of the scraping plate 58 and put it into the drug inlet 39. That is, the first scraping process is performed as the initial charging process.
Subsequently, a first drug collection step and a second scraping step are performed.
In the first drug collection step, the distribution tray 35 is rotated by 3500 pulses as shown in FIG. 13 (d), and the powdered medicine is drawn in front of the scraping plate 57, and the scraping plate 58 is moved as shown in FIG. 14 (e). It rotates to scoop up the powder, discharge it from the distribution tray 35, and put the medicine into the medicine inlet 39.
In the subsequent second drug collection step, the distribution tray 35 is rotated 900 pulses in FIG. 14 (f) and the powder is sprinkled before the scraping plate 57, and the third scraping step is as shown in FIG. 14 (g). The scraping plate 58 is rotated to scoop up the powder, discharge it from the distribution tray 35, and charge the drug into the drug inlet 39.
In the last drug collection step (third time), FIG. 14 (h) rotates the dispensing tray 35 by 600 pulses to scrape the powder in front of the scraping plate 57, and as a fourth scraping step, FIG. ) The scraping plate 58 is rotated to scoop up the powder and discharge it from the distribution tray 35, and the drug is charged into the drug inlet 39.

Through the above steps, a total of one dose of powder is sent to the medicine packaging device 53 and packaged in a single package.
Thereafter, the powder for the second package and the third package are divided into a plurality of times and sent to the drug packaging device 53 by the same procedure, and each package is packaged in one package.
In this method, a series of steps in which a single dose of powder is injected into the drug inlet 39 is divided into four scraping steps and three drug collection steps. The powder for taking is discharged from the distribution tray 35.
According to the method of the present embodiment (divided scraping), the powder is unlikely to spill out during scraping, and there is little variation in the amount of powder contained in one package.

  In particular, if the amount of movement of the dispensing tray 35 in the drug collection process (third time in the above embodiment) corresponding to the last time out of the single dose is less than the amount of other times, There is no need to scrape a lot of powder during the scraping (fourth scraping process). For this reason, it is unlikely that this time the powder will spill and remain in the area where the dose is subsequently scraped. Therefore, according to the present embodiment, it is possible to further improve the distribution accuracy.

In the present embodiment, the powder for one dose is similarly divided into a plurality of times and sent to the drug packaging device 53 in the second package and thereafter. It may be sent to the medicine packaging device 53.
For the second and subsequent packages, the initial charging step may be omitted.
In this embodiment, the powder for a single dose is divided into 3.5 to 0.9 to 0.6 and scraped, but the ratio of the scraping amount is arbitrary. However, it is recommended to reduce the amount of scraping in the final round compared to other rounds.
Alternatively, in the final scraping process, it is also recommended to rotate the scraping plate 57 more slowly than usual.

The divided scraping described above includes the first scraping process, the first drug collecting process, the second scraping process, the second drug collecting process, the third scraping process, the third drug collecting process, The powder for one dose is discharged through the second scraping process, but the number of the scraping process and the drug collection process is arbitrary. An example of the case where the number of steps is the smallest is a case where powder for one dose is discharged by the first scraping step, the first drug collecting step, and the second scraping step.
Divided scraping needs to be collected in front of the scraping plate 57 by at least one drug collection step, and is therefore applied when the distribution area of the powder corresponding to one dose on the distribution plate 36 is excessively small. Hard to do.

  Therefore, it is recommended that the divided scraping is executed when the distribution area of the powder distribution tray to be scraped as a single dose is at least twice the scraping width corresponding to the width of the scraping portion 100. That is, when the distribution area of the powder distribution tray to be scraped as a single dose is more than twice the scraping width corresponding to the width of the scraping portion 100, more accurate powder distribution can be performed by performing split scraping. be able to.

(16) Selection of powder discharge mode In the medicine dispensing device 1 of the present embodiment, the following method can be selected as a method of discharging the powder from the divided dish 35.
A: Normal discharge mode B: All divided scraping mode C: Partially divided scraping mode

The “normal discharge mode” is a discharge mode in which a single dose of powder is discharged from the distribution tray 35 by one drug collection process and one scraping process.
The normal discharge mode is a speed-oriented discharge mode in which the time required to discharge all the powder on the distribution tray 35 is short.

“All division scraping mode” is a discharge mode in which all the parcels are divided and scraped.
The all-particulate scraping mode is a discharge mode that is selected when the amount of powder for a single dose is large or when it is desired to package the powder more precisely.
The all-particulate scraping mode is a scraping mode recommended when the amount of movement (rotation amount) of the dispensing tray corresponding to a dose is large to some extent. In this case, more accurate powder dispensing is performed. can do.
It is done only.
One of the conditions for the “all divided raking mode” is that the distribution area of the powder distribution tray 35 to be scraped as a single dose is at least twice the raking width corresponding to the width of the raking portion 100. Selectable.

The “partially divided raking mode” is a discharge mode in which a part of the parcel is performed in the divided raking mode.
For example, the powder of the first package is discharged from the distribution tray 35 by divided scraping, and the powder for one dose is discharged from the distribution tray 35 by one drug collection process and one scraping process after the second package.

  The switching of the discharge mode may be performed based on the judgment of the pharmacist or may be automatically selected. For example, a control program may be provided so that the entire divided scraping mode is automatically selected when a single dose exceeds a certain amount.

  Also, as an option, for example, “emphasis on speed” or “emphasis on accuracy” is distinguished. When “emphasis on speed” is selected, the normal discharge mode is executed, and when “emphasis on accuracy” is selected. May be executed in the all-divided raking mode or the partially divided raking mode.

(17) Automatic setting of rotation speed of distribution tray In the medicine dispensing apparatus 1 of the present embodiment, the rotation speed of the distribution tray 35 can be changed. In particular, in the medicine dispensing apparatus 1 of the present embodiment, the rotation speed of the distribution tray 35 at the time of the powder drop is automatically changed according to the properties of the powder. In addition, the rotation speed of the distribution tray 35 when the distribution tray 35 is rotated by an angle corresponding to the number of distribution and scraped to the scraping plate 57 (drug collection process) may be automatically changed according to the properties of the powder. Recommended. Further, the rotational speed of the scraping plate 57 of the scraping device 37 may be automatically changed according to the properties of the powder.
The properties of the powder are stored in, for example, an external storage means, and are input to the drug dispensing device 1 as one of prescription information.
As a modification, a particle size discriminating unit for discriminating the particle size of the powder to be prescribed is provided, and the rotation speed of the distribution tray 35 is automatically set according to the determination of the particle size discriminating unit. Conceivable.

As the particle size discriminating means, an optical powder fall sensor is provided in the vicinity of the container mounting device 36, and a method of discriminating the particle size based on the powder fall state detected by the powder fall sensor can be considered.
The above-described powder drop sensor detects whether or not the powder is falling from the drug container 4 to the distribution tray 35. For example, a translucent light sensor or a reflective light sensor may be employed. it can.
A powder fall sensor irradiates light to the fall path | route of a powder, and judges whether the powder is falling by the permeation | transmission state or reflection state of light.
Here, according to the study by the present inventors, in the initial stage when the powder drops from the drug container 4, the detection state of the powder drop sensor differs depending on the particle size of the powder. That is, in many cases, the discharge amount is not stable at the initial stage of powder discharge, but the instability tends to vary depending on the particle size of the powder.
When the particle size of the powder is large, detection and non-detection of the powder are repeated in small increments. That is, when the particle size of the powder is large, the ON state where the powder is detected and the OFF state where the powder is not detected change in small increments.
On the other hand, when the particle size of the powder is small, the time for which the powder is detected is relatively long as compared with the case where the particle size is small.

  By adopting the above-mentioned “control for early initial discharge”, the vibration is strengthened until the medicine reaches the opening 72 at the tip of the medicine container 4, and the medicine reaches the opening 72 at the tip and the powder falls. Then, when it is set as the structure which transfers to a normal vibration, it is desirable to judge the particle size of a powder by monitoring the detection state of the powder drop sensor before shifting to a normal vibration.

(18) Control when using an open type medicine container The medicine dispensing apparatus 1 described above is an operation for taking out the medicine container 4 from the container storage unit 23, an action for moving the taken out medicine container 4 to the vicinity of the distribution tray 35, An operation of placing the medicine container 4 on the container placement device 36 to configure the medicine feeder 8, an operation of supplying a predetermined amount of medicine to the distribution tray 35, and a medicine from the distribution tray 35 to the medicine packaging device 53 for each dose. The operation of supplying and the operation of returning the medicine container 4 to the container storage unit 23 can be automatically performed. Hereinafter, this series of operations is referred to as a fully automatic packaging operation using the sealed drug container 4.
The medicine dispensing apparatus 1 can also use an open type medicine container 60 as shown in FIG. When the medicine container 60 is used, a predetermined amount of powder is weighed out and put into the medicine container 60, the small door 33 is opened, and the medicine container 60 is placed on the container placement device 36 in the housing 10. To do. Then, the shaking table 50 is vibrated to drop all the powder in the medicine container 60 from the medicine container 60 onto the distribution tray 35.
The medicine container 60 that has finished discharging the powder is taken out from the housing 10.
Both the operation of placing the medicine container 60 on the container placement device 36 and the operation of taking out the medicine container 60 from the housing 10 are performed manually. Hereinafter, a series of operations when using the medicine container 60 is referred to as semi-automatic packaging operation using the open medicine container 60.

  In the semi-automatic packaging operation, when the powder drops from the medicine container 60 are finished, the operation of the medicine dispensing device 1 is stopped until the medicine container 60 is manually removed from the housing 10.

Further, the packaging operation in the medicine dispensing apparatus 1 is performed in the order of the prescription information input to the medicine dispensing apparatus 1.
As described above, when the packaging operation is performed in the order of input to the medicine dispensing device 1, when the powder medicine 60 has been supplied from the medicine container 60 to the distribution tray 35 using the open medicine container 60, the casing 10 There is dissatisfaction that the processing based on the next prescription cannot be performed until the used medicine container 60 is taken out from the container.

For example, it is assumed that the following information about the first prescription, the second prescription, and the third prescription is input in order.
First prescription A drug (use semi-automatic packaging open type drug container 60)
Drug B (uses sealed drug container 4)
Second prescription B drug (uses sealed drug container 4 that can be fully automatically packaged)
Drug C (uses a fully automatic sealed medicine container 4)
Drug D (completely automatic packaging possible, using sealed drug container 4)
Third prescription B medicine (fully automatic packaging possible, using sealed medicine container 4)
Drug C (uses a fully automatic sealed medicine container 4)

In the medicine dispensing device 1 described above, three container mounting devices 36 are installed for one distribution tray 35, and the powder medicine can be dropped from the three medicine containers 4 onto the distribution tray 35.
In the above example, in the first prescription, the medicine A and the medicine B are prescribed, and two container mounting devices 36 are used. In the second prescription, B medicine, C medicine and D medicine are prescribed, and three container mounting devices 36 are used. In the third prescription, the B medicine and the C medicine are prescribed, and two container mounting devices 36 are used.

If the user forgets to take out the open medicine container 60 after supplying powder to the distribution tray 35 based on the first prescription, the process based on the second prescription cannot be started.
That is, in the medicine dispensing device 1 described above, three container placement devices 36 are installed for one distribution tray 35, and powder can be supplied from the three medicine containers 4 to the distribution tray 35. However, at the stage where the processing of the first prescription is completed, the open type medicine container 60 remains in one container mounting device 36.
On the other hand, since the second prescription is prescription of A medicine, B medicine, and C medicine, it is necessary to use three container mounting devices 36, but it opens to one container mounting device 36. Since the type of drug container 60 remains, only two container mounting devices 36 can be used, and the second prescription cannot be processed.

As a countermeasure against this, it is conceivable to adopt a control for automatically changing the prescription processing order and implementing a prescription that can be processed.
That is, in a normal case, the packaging operation is performed in the order input to the medicine dispensing apparatus 1.
If a semi-automatic packaging operation using the open type drug container 60 is performed on the way and the open type drug container 60 remains in the container mounting device 36, the processing of the second prescription is postponed. A third prescription process is performed.
That is, it is detected whether or not there are the medicine containers 4 and 60 in the container mounting device 36. In other words, the number of usable container placement devices 36 is detected, and prescription information that can supply the necessary powder to the distribution tray 35 is selected only by the usable container placement device 36 to perform the packaging process.
If this control method is adopted, the stop time of the medicine dispensing apparatus 1 can be shortened, and the number of processes per day can be increased.

(19) Placement Order of Drug Containers on Container Placement Device As described above, the drug dispensing device 1 has three container placement devices 36 installed on one distribution tray 35, and three The powder can be dropped from the drug container 4 to the distribution tray 35. For example, the medicine container 4 filled with E medicine is taken out from the container storage unit 23, the medicine container 4 is placed on one container placing device 36, and the vibrating table 50 is vibrated, and the medicine container 4 is transferred to the distribution dish 35. E Drop the drug.
During this time, the medicine container 4 filled with the F medicine is taken out from the container storage section 23, and the medicine container 4 is placed on an empty container placement device 36, and the fall of the F medicine starts.
Further, during this time, the medicine container 4 filled with the G medicine is taken out from the container storage unit 23, and the medicine container 4 is placed on an empty container placement device 36, and the dropping of the G medicine is started.

  Here, the placement order of the medicine container 4 on the container placement device 36 is the order in which the total amount of powdered powder is large. In other words, the larger the total amount of powder prescribed, the longer the time required to finish supplying the required amount to the distribution tray 35 is expected. Then, the medicine container 4 filled with the powder that takes a long time to complete the supply is first placed on the container placement device 36, and by starting the fall of the powder early, all the powders (E medicine, It is possible to shorten the time required to finish the fall of the F medicine and the G medicine).

However, the time required to drop a certain amount of powder from the drug container 4 is not the same for all types of powder, and there are powders that are easily discharged from the drug container 4 and powders that are difficult to be discharged.
Therefore, even if the total amount to be dropped is small, some powders have a long time to drop the required amount of powder. The user may arbitrarily set the order of placing the medicine container 4 on the container placement device 36 so as to flexibly cope with such powder.
Further, a configuration may be adopted in which a coefficient is assigned to each powder, and the placement order of the medicine container on the container placement device is automatically set in consideration of the coefficient and the total amount of powder prescribed. Alternatively, the priority order may be set for each powder or for each medicine container 4, and the medicine containers 4 may be installed on the container placement device 36 in descending order of priority.

(20) Missing Item Display In the medicine dispensing device 1 of the present embodiment, the remaining amount of powder in the medicine container 4 can be displayed on the operation display unit 3 by performing a predetermined operation.
For example, the operation display unit 3 is operated to call up information on a specific medicine container 4. The information of the medicine container 4 includes the remaining amount of powder inside.
Further, in the medicine dispensing apparatus 1 of the present embodiment, it is possible to search for the medicine container 4 whose remaining amount is low by operating the operation display unit 3.
For example, it is possible to set a threshold value for the remaining amount in each medicine container 4 and select only the medicine container 4 that is equal to or less than the threshold value and display it on the operation display unit 3.
Furthermore, without operating the operation display unit 3, the operation display unit 3 may display the number or the like of the drug container 4 in which the remaining amount of the powder is equal to or less than the threshold value. That is, after the processing for one prescription is completed, when the remaining amount of powder in the medicine container 4 is equal to or lower than the threshold value, the operation display unit 3 is automatically notified without any special operation, and the remaining amount is low. The drug container 4 that has become is identified.

(21) Processing in the case of a small amount prescription For example, in the case of prescription for infants, the amount of powder prescribed may be small. On the other hand, in the medicine dispensing device 1, there is a lower limit to the amount of individual powder supplied to the distribution tray 35. Therefore, in principle, when the powder described in the prescription includes powder whose total amount is less than the lower limit, it cannot be packaged.
That is, in the medicine dispensing device 1, the powder is dropped on the distribution tray 35 while rotating the distribution tray 35, and the powder is evenly dispersed in the medicine loading groove 32. However, when the amount of the medicine is excessively small, It is difficult to uniformly disperse the powder in the drug insertion groove 32.

In this embodiment, when the total amount of the powder is small, the powder exceeding the lower limit is dropped onto the distribution tray 35. Then, the powder in the distribution tray 35 is divided into a larger number than necessary, and the amount of powder contained in each package is adjusted to the amount of prescription usage.
For example, suppose that it is necessary to pack 0.1 grams of H drug in a package and make 3 packages. On the other hand, it is assumed that the lower limit of powder that can be packaged is 0.5 grams.
If this is the case, 0.5 gram of powder is dropped from the drug container 4 and dispersed in the distribution tray 35.

Then, the powder medicine dispersed in the distribution tray 35 is divided into five parts and put into the medicine inlet 39 to make five medicine packs of 0.1 gram per package.
And hand 3 packages to the patient. The remaining two packages are discarded or the package is broken and the powder is taken out and returned to the original drug container 4.
Hereinafter, an unnecessarily made medicine package is referred to as “discard”.

Here, in the medicine dispensing device 1 according to the present embodiment, the following measures are taken so as not to cause an error in the final inspection before the patient is administered.
(A) The number of discarded packages is displayed on the dispensing recording sheet. The dispensing recording sheet is printed out from the medicine dispensing device 1 or the control device connected to the medicine dispensing device 1. On this dispensing record sheet, the number of medicine packages to be handed over to the patient and the number of discarded packages are displayed.
(B) Printing to the effect of “discarded” on the medicine packaging The medicine packaging area 14 of the medicine dispensing device 1 is provided with the printing means as described above. The patient name and the like are printed on each medicine package by the printing means.
In the medicine dispensing apparatus 1 of the present embodiment, characters, symbols, and the like indicating “discarded” are printed on the discarded drug package.

Furthermore, in the present embodiment, the type of the internal powder and the characters and symbols that specify the original drug container 4 are printed on the discarded package. In addition, characters and symbols for distinguishing whether the powder in the discarded package is one type or plural types are also printed.
For example, although not shown in the drawings, a medicine dispensing device has conventionally been equipped with a device for automatically drawing a line with a pen on the medicine packaging, and a single kind of medicine or a plurality of medicines are mixed by the automatic line drawing apparatus. Different color lines may be applied to the medicine package so that it can be determined whether the medicine has been applied.
Further, for example, a readable code such as a barcode for identifying the original drug container 4 or drug bottle is printed on the drug package.
When a plurality of powders are mixed in the discarded package, it cannot be reused and is discarded. If there is only one type of powder in the discarded package, it cannot be reused, and the powder is returned to the specific drug container 4 as necessary. In this case, the code of the medicine packaging is read with a code reader. Then, the drug container 4 is specified using the read code, and the powder medicine in the package is returned to the drug container 4.

(22) Display of Usage Amount In the medicine dispensing apparatus 1 of the present embodiment, the container storage unit 23 is inside, and a large number of medicine containers 4 are held in the container storage unit 23.
In principle, in the medicine dispensing apparatus 1, the medicine container 4 accommodated in the medicine dispensing apparatus 1 is moved to the container placement device 36 by the container moving means 28, and the powder medicine is supplied from the medicine container 4 to the distribution tray 35.
On the other hand, the medicine dispensing apparatus 1 of the present embodiment moves the medicine container 4 stored outside to the container mounting device 36 manually or by the container moving means 28, and distributes the medicine from the medicine container 4 stored outside to the distribution tray 35. You can also drop the powder.

In the medicine dispensing device 1 of the present embodiment, the operation display unit 3 can be operated to display the amount of powder consumed within a certain period for each medicine type. Further, it can be rearranged based on a predetermined condition.
For example, they can be displayed side by side in descending order of consumption within a certain period. Or it can also arrange and display in order with many prescriptions. In addition, it is possible to display which medicine container 4 contains the medicine. At this time, the location of the medicine container 4 can also be displayed.
That is, in the medicine dispensing apparatus 1, in principle, the powder medicine is dropped from the medicine container 4 accommodated in the medicine dispensing apparatus 1 onto the distribution tray 35, but the medicine container 4 stored on an external shelf or the like is manually or container moving means 28. It is possible to move to the container mounting device 36 and drop the powder from the medicine container 4 stored outside to the distribution tray 35.
In the medicine dispensing apparatus 1 of the present embodiment, the medicines rearranged under a predetermined condition are stored in which medicine container 4, and the medicine container 4 is further stored in the container storage unit 23 in the medicine dispensing apparatus 1. It is possible to display whether it is held on the shelf or stored on an external shelf or the like.

  According to this embodiment, it is possible to know which drug container 4 is frequently used. Therefore, for example, if the medicine container 4 with low usage frequency is in the medicine dispensing apparatus 1 and the medicine container 4 with high usage frequency is outside the medicine dispensing apparatus 1, they are exchanged to replace the medicine container 4 with high usage frequency. It can be accommodated in the medicine dispensing device 1.

In the medicine dispensing device 1 of the present embodiment, the remaining amount of powder in each medicine container 4 is monitored. When the remaining amount of powder in the medicine container 4 decreases below a certain threshold value, a message to that effect is displayed on the operation display unit 3. That is, the medicine container 4 and the type of powder are specified, and a predetermined “missing item notice” is displayed on the operation display unit 3. A predetermined filling guide is also displayed.
Specifically, the medicine container 4 whose remaining amount is reduced, the name of the powder to be accommodated in the medicine container 4, and the like are displayed as filling guidance.

In the medicine dispensing apparatus 1 according to the present embodiment, in order to prevent the powder in the medicine container 4 from running out when the medicine is supplied from the medicine container 4 to the distribution tray 35, a shortage notice is displayed on the operation display unit 3. Is displayed, the packaging operation based on the next prescription is interrupted until the user performs a predetermined process.
Specifically, after a packaging operation is performed based on one prescription, if a shortage notice is displayed on the operation display unit 3, the content based on the next prescription is displayed until the user manually releases it. Wrapping does not start.

In the medicine dispensing apparatus 1 according to the present embodiment, the following four types of actions that can be taken when a shortage notice is displayed on the operation display unit 3 can be selected as an initial setting or a user setting.
(A) When the “Notice of shortage” is displayed, the user can manually release it to perform a packaging operation based on the next prescription.
(B) If “Notice of Missing Items” is displayed, the medicine container 4 subject to the “Notice of Missing Items” is filled with a predetermined powder, and the medicine container 4 is returned to the container storage unit 23. The packaging operation based on the following prescription becomes possible.
(C) If “Notice of Missing Items” is displayed for a certain period of time and the user does not manually cancel “Notice of Missing Items” during that time, the packaging operation based on the next prescription becomes possible. However, the prescription information that uses the drug container 4 that is the target of “out of stock notice” is moved to a specific memory area as a “out of stock prescription list” and removed from the normal processing order.
(D) Even when “Notice of missing parts” is displayed, the packaging operation based on the next prescription can be performed without displaying the filling guide. However, the prescription information that uses the drug container 4 that is the target of “out of stock notice” is moved to a specific memory area as a “out of stock prescription list” and removed from the normal processing order.

When the above setting of C or less is adopted, it is possible to prevent the interruption time of the packaging operation from becoming excessively long.
In other words, when “Notice of missing item” is displayed as in A, the packaging operation based on the following prescription is possible on condition that the user manually releases it, or “ If the setting is made so that the packaging operation based on the following prescription is possible on condition that the medicine container 4 subject to the “notice” is additionally filled with a predetermined powder, the user must be aware of the “missing notice”. In some cases, the interruption time of the packaging operation becomes long.
On the other hand, when the setting of C or less is adopted, the packaging operation based on the next prescription can be started without the user being aware of the “missing product notice”. It is possible to prevent the time from becoming excessively long.

The handling of the prescription moved as the “shortage prescription list” can be selected from the following two types as an initial setting or a user setting.
(A) The information based on the prescription is the “Missing Prescription List” when a predetermined powdered medicine is filled in the drug container 4 subject to “Notice of Missing Items” and the drug container 4 is returned to the container storage unit 23. ”Is returned to the original memory area, and the packaging operation is started in the order of the prescription reception time.
(B) The “out of stock list” is displayed by a predetermined operation, and the packaging operation is started by the user's selection.
