Description

  The present invention relates to a medicine dispensing device, and more particularly to a medicine dispensing device provided with a distribution tray for dispensing powder.

In large hospitals and large-scale pharmacies, drug dispensing devices having a powder dispensing function have been introduced. The conventional medicine dispensing device has a structure as disclosed in Patent Document 1, and is a combination of a distribution tray and a powder feeder.
The pharmacist operates the device in accordance with a doctor's prescription to divide the powder using the conventional medicine dispensing device. 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.
That is, if it is a powder taken three times a day and is prescribed 1.0 gram per dose, and 20 days of medication is prescribed, (1.0 × 3 × 20 = 60) grams Of powder is taken out. More specifically, a container is placed on a scale, tared, and a powdered spoon is used to take out the powder from the medicine bottle, put the powder in a container on the scale, and weigh 60 grams of powder.

Then, the weighed 60 grams of powder is put into the feeding 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.
The powder charged in the charging hopper falls on the trough of the powder feeder, and when the trough vibrates, the powder slowly moves to the tip side and falls into the groove of the distribution tray.

On the other hand, since the distribution tray rotates at a predetermined speed, the powder falling from the trough is evenly distributed in the grooves of the distribution tray.
When the powder falls on the distribution tray, the rotation of the distribution tray is once stopped. Thereafter, the disc of the scraping device is dropped into the groove of the distribution tray. Thereafter, the distribution tray is rotated by an angle corresponding to the distribution number. In the previous example, 60 grams of powder is packaged into 60 packets, so the dispensing pan is rotated by (6/360) degrees and the powder is collected on the front side of the disk by (6/360) degrees. Then, the disk is rotated, and the powder for (6/360) degrees 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. That is, in the conventional powder medicine packaging device, it is indispensable for a pharmacist to take out a medicine bottle containing a desired medicine from a medicine shelf and to measure a predetermined amount of powder from the medicine bottle.

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.

  In the medicine dispensing device disclosed in Patent Document 2, a plurality of medicine containers are stored in a container storage unit, but each medicine container is filled with a different type of powder. That is, there is a one-to-one correspondence between the drug container and the powder type, and there is only one drug container filled with one type of powder, and the same type of powder is not filled in a plurality of drug containers.

Further, the position where each medicine container 4 is accommodated is also stored.
As described above, several drug containers 4 are attached to the container storage unit 23 in the container arrangement region 12.

In actual work, the medicine container 4 is installed in the container temporary placement section 18 provided in the door section 16, and then the door section 16 is closed and the medicine container 4 is placed in the housing 10.
By closing the door portion 16, a safety device (not shown) is released, the container moving means 28 and the like can be operated, the container moving means 28 automatically operates, and the drug container 4 is stored in the container storage area 12 in the container arrangement area 12. 23, and stored in the container storage unit 23. That is, the container introduction operation is performed by the container moving means 28.
The container temporary placement unit 18 has information reading means, and the introduced medicine container 4 is specified. That is, information such as the container group to which the introduced drug container 4 belongs, the type of powdered powder filled, and the filling amount is read and stored in the control unit 11.
Further, when the medicine container 4 is placed on the container temporary placement part 18, the weight of the medicine container 4 is measured by the weight measuring means, and the filling amount of the powder is confirmed.

Next, a series of packaging operations performed using the medicine dispensing apparatus 1 of the present embodiment will be described.
In the medicine dispensing apparatus 1 of the present embodiment, information related to the prescription is input, and the packaging work 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 information on the prescription, and the necessary medicine container 4 is loaded from the container storage section 23 into the container mounting 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 vibration means 51 is energized with a constant frequency 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. More specifically, the weight of the medicine container 4 is obtained by subtracting the weight of the member above the weight measuring means 52 of the container mounting device 36 from the detected weight of 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. Here, in the present embodiment, since the medicine container 4 is firmly joined to the vibration table 50 by the magnet 41 and the degree of close contact with the vibration table 50 is high, the medicine container 4 has the same frequency as the vibration table 50. Vibrate. As a result, the powder stored in the medicine container 4 slowly moves toward the opening 188 side, is discharged from the opening 188 and falls.

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 falls from the opening 188 of the drug container 4. Then, the original weight G of the drug container 4 immediately after installation on the vibration 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, when 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 vibration start measured by the weight measuring means 52, the vibration of the shaking table 50 is stopped. .

Further, before stopping the vibration of the vibration table 50, it is desirable to operate in a state where the amplitude of the vibration table 50 is reduced and the vibration frequency is lowered.
For example, if the current powder discharge amount is the amount that finally discharges the powder (target discharge amount) minus several grams, the amplitude of the shaking table 50 is reduced and the vibration frequency is lowered. Drive in a wet state. The remaining several grams are discharged in a state where the amplitude of the vibration table 50 is reduced and the vibration frequency is lowered.
As described above, when the total amount H of the powder drops reaches a desired weight, the vibration of the shaking table 50 is stopped.
Thereafter, the container moving means 28 automatically operates, and the drug container 4 is returned to the container storage unit 23 in the container arrangement region 12.

When all the powder in the medicine container 4 is discharged and the medicine container 4 becomes empty, the medicine container 4 is replaced. When the medicine container 4 is replaced, the vibration of the container placement device 36 is stopped, and the weight of the medicine already discharged from the medicine container 4 is stored.
The procedure for replacing the medicine container 4 differs depending on whether or not the medicine container 4 belonging to the same container group exists in the container storage unit 23 in the container arrangement region 12.
As described above, in this embodiment, the drug containers 4 are grouped, and a plurality of drug containers 4 may belong to the same container group. And the medicine container 4 which belongs to the same container group is filled with the same kind of powder.

Moreover, even if it is the chemical | medical agent container 4 which belongs to the same container group, not all are equipped with the container storage part 23 of the container arrangement | positioning area | region 12.
Therefore, when the powder in the medicine container 4 is exhausted while the powder is being discharged from the medicine container 4 and the medicine container 4 is empty, the medicine containers 4 belonging to the same container group are placed in the container arrangement region. It is searched whether or not there are 12 container storage units 23.
If the medicine containers 4 belonging to the same container group are present in the container storage section 23 in the container arrangement region 12, the container moving means 28 automatically starts to operate, and the medicine actually mounted on the container placement device 36 The container 4 is removed and returned to the container storage unit 23, and the medicine container 4 belonging to the same container group is newly detached from the container storage unit 23 and mounted on the previous container mounting device 36.

Alternatively, the drug container 4 that is actually mounted on the container mounting device 36 is left as it is without being removed, and a new drug container 4 belonging to the same container group is removed from the container storage unit 23 to another container mounting device 36. Installing.
In any case, the medicine containers 4 belonging to the same container group are mounted on the container mounting device 36 corresponding to the same distribution tray 35.

When it is confirmed by a sensor or the like (not shown) that the medicine containers 4 belonging to the same container group are mounted on the container placement device 36, the vibration of the container placement device 36 is restarted, and the new medicine container 4 starts the distribution tray. Drop powder to 35.
When the medicine container 4 is left as it is without being removed, the container mounting device 36 to which the new medicine container 4 is attached is vibrated to drop the powder from the new medicine container 4 onto the distribution tray 35.
As described above, since the weight of the medicine discharged from the medicine container 4 by the time when the work is interrupted is stored, the powder medicine is discharged from the new medicine container 4 by the remaining discharge amount, and then the container placement device 36 Stop vibration.

On the other hand, when there are no medicine containers 4 belonging to the same container group in the container storage unit 23 in the container arrangement region 12, “Missing product display” is displayed on the operation display unit 3.
“Missing product display” is automatically displayed on the operation display unit 3 when the medicine container 4 filled with powder to be prescribed is not in the medicine dispensing apparatus 1. The missing item display is a conspicuous display so that the user is interested. In addition, information for identifying a powder that has become insufficiency such as a number or a symbol for identifying the drug container 4 or a type of the powder is also displayed.

Then, a predetermined shortage processing step is executed.
Also in the stockout process, the weight of the medicine discharged from the medicine container 4 is already stored.

In the present embodiment, the container discharging operation is executed in the shortage processing step. That is, the drug container 4 is taken out using the container moving means 28. Specifically, the vibration of the container mounting device 36 is stopped. Then, the container moving means 28 automatically operates, and the medicine container 4 is removed from the container mounting device 36. Then, the drug container 4 is moved to the container temporary placement part 18 provided in the door part 16 by the container moving means 28.
When the medicine container 4 is installed in the container temporary placement part 18 provided in the door part 16, the door part 16 is automatically opened. The user takes out the medicine container 4 from the container temporary placement section 18 and checks the inside of the medicine container 4.
If there is no powder in the medicine container 4, the medicine container 4 is replenished with the powder and placed in the container temporary placement unit 18 again.

  In the case where there are no medicine containers 4 belonging to the same container group in the container storage section 23 of the container arrangement area 12, but there are medicine containers 4 belonging to the same container group outside the medicine dispensing apparatus 1, the container group A new medicine container 4 belonging to the above may be installed in the container temporary placement unit 18.

  In this embodiment, the following container introduction operation | movement is performed by installing the chemical | medical agent container 4 in the container temporary placement part 18 in which the door part 16 was provided, and performing predetermined operation.

  That is, the group of the medicine containers 4 attached by the information reading means of the container temporary placement unit 18 is confirmed. When it is confirmed that the medicine container 4 attached to the container temporary placement unit 18 is the medicine container 4 previously removed or the medicine container 4 belonging to the same container group, the container moving means 28 automatically The medicine container 4 is mounted on the previous container mounting device 36. In addition, as long as the mounting destination of the medicine container 4 corresponds to the same distribution tray 35, any container mounting device 36 may be used. In the container temporary placement unit 18, the weight of the drug container 4 is measured, and the filling amount of the powder is confirmed.

  When it is confirmed by a sensor or the like (not shown) that the medicine containers 4 belonging to the same container group are mounted on the container placement device 36, the vibration of the container placement device 36 is restarted, and the new medicine container 4 starts the distribution tray. Drop powder to 35. Even in this case, since the weight of the medicine discharged from the medicine container 4 is stored until the operation is interrupted, the powder medicine is discharged from the new medicine container 4 by the remaining amount of discharge, and the container placement device 36 is then vibrated. Stop.

As described above, since the number n of drug containers 4 that can belong to one container group is arbitrary, three or more drug containers 4 belong to the same container group, and three or more drug containers 4 are arranged in a container. In some cases, the container storage unit 23 in the region 12 is equipped.
In that case, one of the medicine containers 4 belonging to the container group is selected, moved to the container placing device 36 by the container moving means 28, placed on the container placing device 36, and the powdered medicine is put into the distribution tray 35. Will be.
Hereinafter, a rule for selecting the medicine container 4 including a part overlapping with the above description will be described. According to the rules described below, there is a medicine container 4 that is actually placed on the container placement device 36 and discharges the powder, and all the powder in the medicine container 4 is discharged, and the medicine container 4 is empty. In this case, it is a rule for selecting a new medicine container 4 in order to restart the packaging operation.

(1) When only one medicine container 4 belonging to the same container group is installed in the container storage unit 23 of the container arrangement region 12, that is, when the number n is 1 and the number n is 2 or more, Only one medicine container 4 is attached to the container storage unit 23 in the container arrangement area 12 and the other is outside the medicine dispensing apparatus 1.
In this case, since the medicine container 4 to be replaced does not exist in the container storage unit 23, the container discharging operation is executed as described above, and the medicine container 4 that is currently used is discharged from the casing 10 and the powder is re-used. A separate or additional drug container 4 belonging to the same group is required. That is, the shortage processing step is executed.

(2) When two medicine containers 4 belonging to the same container group are installed in the container storage unit 23 in the container arrangement region 12, that is, when the number n is 2 and the number n is 3 or more, 2 This is the case where only one medicine container 4 is mounted on the container storage unit 23 in the container arrangement region 12 and the other is outside the medicine dispensing apparatus 1.
In this case, only one medicine container 4 to be replaced exists in the container storage unit 23.
In this case, as described above, the medicine container 4 remaining as a spare in the container storage unit 23 is placed on any container placement device 36 by the container moving means 28, and the powder medicine is discharged from the new medicine container 4. It is put into the distribution tray 35.
In addition, when the medicine container 4 left as a spare in the container storage unit 23 in the container arrangement area 12 is empty, a shortage processing step is executed. In this case, the medicine container 4 that is actually placed on the container placing device 36 is discharged from the housing 10.

(3) When three or more drug containers 4 belonging to the same container group are installed in the container storage unit 23 of the container arrangement region 12, that is, when the number n is 3, the number n is 4 or more, This is a case where three or more medicine containers 4 are mounted on the container storage unit 23 in the container arrangement region 12 and the others are outside the medicine dispensing apparatus 1.
In this case, two or more drug containers 4 remain in the container storage unit 23 as a spare.
In this case, from the drug containers 4 left in the container storage unit 23 as a reserve, the one with the powder remaining is selected, and the drug container 4 selected from among the drugs is mounted on the container mounting device 36. The powder medicine is put into the distribution tray 35 from the new medicine container 4.

When there are a plurality of drug containers 4 with powders remaining, the drug container 4 to be used is selected according to the rule selected by setting.
In this embodiment, the following rules are prepared as selectable rules.

(Selection A)
Selection A is a measure in which the remaining amount of powder in the drug container 4 is examined, and a powder with a large remaining amount is preferentially selected.
According to this measure, it is possible to delay the time for executing the shortage process.

(Selection B)
Selection B is a measure for examining the remaining amount of powder in the drug container 4 and preferentially selecting a powder with a small remaining amount.
According to this measure, the interval of the shortage process becomes a constant interval.

(Selection C)
The selection C is a measure for examining the time when the medicine container 4 is filled with the medicine and preferentially selecting the one with the new filling time.
According to this measure, it is possible to delay the time for executing the shortage process.

(Selection D)
The selection D is a measure for checking the time when the medicine container 4 is filled with the medicine and preferentially selecting the one with the old filling time.
According to this measure, it is possible to prevent the powder from expiring.
Further, it is desirable to check the remaining amount of powder in the medicine container 4 and compare the amount of the powder necessary for the distribution operation to be performed and the remaining amount, and select the remaining amount sufficient for the necessary amount.
In the present embodiment, the medicine container 4 whose remaining amount is sufficient for the required amount is searched first. In the present embodiment, (Selection D) is adopted, and among the drug containers 4 whose remaining amount is sufficient, the drug container 4 with the old filling time is preferentially used.

The flowcharts shown in FIGS. 9 and 10 explain the above-described series of operations.
That is, in step 1, waiting for the prescription to be input, and if the prescription is accepted, the process proceeds to step 2 and the packaging operation is started.
In step 2, the contents of the prescription are confirmed, and it is confirmed whether or not the medicine container 4 filled with the powder to be prescribed is in the medicine dispensing apparatus 1. If there is a medicine container 4 corresponding to the container storage unit 23 of the medicine dispensing device 1 or if any medicine container 4 corresponding to any container placement device 36 is placed, step 2 becomes YES, and the next step Proceed to step 3.

In step 3, it is determined whether there is an unused medicine container 4 in the medicine dispensing apparatus 1. In the present embodiment, the “unused state” means a state that is not actually mounted on the container mounting device 36 and that no powder is discharged. It does not matter whether there is a track record used in the past. The “used state” refers to what is actually mounted on the container mounting device 36.
Specifically, it is determined whether or not there is a medicine container 4 corresponding to the container storage unit 23 of the medicine dispensing apparatus 1.

In the subsequent step 4, it is determined whether or not there is a medicine in a necessary amount remaining in the unused medicine container 4.
If any of the unused drug containers 4 still have a necessary amount of powder, the process proceeds to step 5 to determine the time when the drug container 4 is filled with the above-mentioned “selection D”. Check and select the one with the old filling time. If there is one medicine container 4 in which a necessary amount of powder remains, the medicine container 4 is inevitably selected.

  If there is no unused drug container 4 in which a necessary amount of powder remains, the process proceeds to step 6. If there are a plurality of unused drug containers 4, the drug containers 4 are selected according to a predetermined order. In the present embodiment, the drug container 4 having a young branch number is selected.

When the drug container 4 is selected in step 5 and step 6, the process proceeds to step 7 where the drug container 4 selected by the container moving means 28 is transported from the container storage unit 23 to the container mounting device 36.
In step 8, the vibration of the vibration table 50 is started. Prior to the start of vibration, the weight of the medicine container 4 is measured by the weight measuring means 52 of the container mounting device 36. Although omitted in the flowchart, the distribution tray 35 is rotated around the start of vibration.

In step 9 and step 30, it is monitored whether or not the powder is continuously discharged from the drug container 4 and whether or not a desired amount of powder is discharged.
That is, in step 9, it is monitored whether or not the powder in the medicine container 4 is in a shortage state (a state in which the powder in the medicine container 4 is completely exhausted). If it is not in the shortage state, the routine proceeds to step 30, where it is confirmed whether or not the desired amount has been discharged.
If the discharge of the desired amount is completed, the discharge of the powder is finished and the drug container 4 is returned to the container storage unit 23.
If the desired amount has not been discharged, the process returns to step 9.

  If the required amount of powder in the drug container 4 is insufficient and the powder in the drug container 4 is exhausted and a shortage occurs, the process proceeds to step 10 and the vibration of the shaking table 50 is interrupted. Further, the weight of the medicine already discharged from the medicine container 4 in step 11 is stored.

Subsequently, the process proceeds to step 12, where it is determined whether or not there are unused drug containers 4 belonging to the same container group in the container storage unit 23 in the container arrangement region 12.
If there are unused drug containers 4 belonging to the same container group in the container storage unit 23, the same operations as in Steps 4, 5, and 6 are performed. That is, it is determined in step 13 whether or not there is a necessary amount of powder remaining. In step 14, the one with the old filling time is selected, and in step 15, the younger drug container 4 is selected. .

Thereafter, the process proceeds to step 16 where the container moving means 28 automatically operates, and the empty medicine container 4 is returned to the container storage unit 23 in the container arrangement region 12.
At this time, “internal shortage display” is displayed on the operation display unit 3.
“Internal shortage display” is a display notifying that there is an empty medicine container 4 in the container storage unit 23. Even when there are a plurality of drug containers 4 belonging to the same container group in the container storage unit 23, some of them are empty and some of the drug containers 4 remain powdered, “Out of stock” appears. The “internal shortage display” omits the information displayed compared to the “out of stock display” described above. Further, it is more conservative than the “out of stock display” described above, and is less conspicuous than the “out of stock display”.
In the “internal shortage display”, a fact that there is an empty medicine container 4 in the container storage unit 23, a number for identifying the medicine container 4, and the like are displayed.
When the user manually operates the operation display unit 3 at a convenient time, detailed contents are displayed.
Further, when the user operates a specific switch (for example, a shortage button), the empty drug container 4 is transported from the container storage unit 23 to the container temporary storage unit 18 by the container moving means 28.

  Then, the process returns from step 16 to step 7, and the medicine container 4 selected by the container moving means 28 is transported from the container storage unit 23 to the container mounting device 36.

Hereinafter, the above-described process is executed again, and the vibration of the shaking table 50 is started in step 8, whether the powder is continuously discharged from the drug container 4 in step 9 and step 30, and whether a desired amount of powder is discharged. Whether or not is monitored. When the discharge of the desired amount is completed, the discharge of the powder is terminated, and the drug container 4 is returned to the container storage unit 23.
When the powder in the drug container 4 is exhausted and the product is in a shortage state, the process proceeds to step 10 where the vibration of the vibration table 50 is interrupted, the weight of the drug discharged in step 11 is stored, and the same in the container storage unit 23 in step 12 It is determined whether or not there is a medicine container 4 belonging to the container group, and it is determined in step 13 whether or not there is a necessary amount of powder remaining. In step 14, the one with an old filling time is selected. In step 15, the youngest drug container 4 is selected. Thereafter, the process proceeds to step 16, where the container moving means 28 automatically operates, and the empty medicine container 4 is returned to the container storage part 23 in the container arrangement region 12, and the process returns to step 7.

  As a result of confirming the content of the prescription in the step 2 described above, if the medicine container 4 filled with powder to be prescribed is not in the medicine dispensing device 1, the process proceeds to step 17 and the operation display unit 3 displays a predetermined value. The shortage display is performed, the use of the external medicine container 4 is prompted, and the shortage processing step is executed.

That is, the process proceeds to step 18 where the door 16 is opened.
The user carries the external medicine container 4 from the external shelf 5, installs the medicine container 4 in the container temporary placement portion 18, and then operates the switch for closing the door portion 16 to close the door portion 16.
If it is confirmed in step 19 that the medicine container 4 has been installed in the container temporary placement unit 18 and further in step 20 that the switch has been operated, the process proceeds to step 21 where the container moving means 28 is automatically operated. The medicine container 4 is moved to the container mounting device 36.
Thereafter, the process proceeds to step 8 where the vibration of the shaking table 50 is started, and the series of operations described above are executed.

In addition, the powder in the medicine container 4 is exhausted and the product becomes a shortage state. In step 10 described above, the vibration of the shaking table 50 is interrupted, and in step 11 the weight of the medicine already discharged from the medicine container 4 is stored. If there is no medicine container 4 belonging to the same container group in the container storage unit 23 after the transition, but the step 12 is NO, the process proceeds to the step 22.
Then, it is determined whether there is a medicine container 4 in use in the same container group.
When there is a drug container 4 in use in the same container group, the process waits for the drug container 4 to return to the container storage unit 23. That is, step 22 and step 12 are repeated, and a series of operations are resumed after step 12 is changed to YES.

  If there is no medicine container 4 in use in the same container group, the process proceeds to step 23, a predetermined shortage display is performed on the operation display unit 3, and the use of the external medicine container 4 is prompted, A stockout process is performed.

That is, the process moves to step 24, where the container moving means 28 automatically operates to place the medicine container 4 placed on the container placing device 36 in the container temporary placement unit 18.
And it transfers to step 25 and the door part 16 is opened.
The user removes the medicine container 4 from the container temporary placement section 18, carries the external medicine container 4 from the external shelf 5, etc., installs the medicine container 4 in the container temporary placement section 18, and then closes the door section 16. To close the door 16.

In step 26, it is confirmed that the original medicine container 4 has been removed from the container temporary placement unit 18,
If it is confirmed in step 27 that the medicine container 4 has been installed in the container temporary placement unit 18 and further in step 28 it is confirmed that the switch has been operated, the process proceeds to step 29 where the container moving means 28 is automatically operated. The medicine container 4 is moved to the container mounting device 36.
When the medicine container 4 is installed in the temporary container placement unit 18, the medicine container 4 is specified by the information reading means, and the container group to which the medicine container 4 belongs is confirmed. Then, it is confirmed whether or not the medicine container 4 installed in the container temporary placement section 18 belongs to the same container group as the medicine container 4 previously removed. If they are not the same, an error is displayed on the operation display section 3. The
Thereafter, the process proceeds to step 8 where the vibration of the shaking table 50 is started, and the series of operations described above are executed.

Further, the medicine dispensing device 1 of the present embodiment has two distribution trays 35 as shown in FIGS. Therefore, when two or more medicine containers 4 belonging to the same container group are installed in the container storage unit 23 in the container arrangement region 12, the same type of powder can be simultaneously supplied to the two distribution dishes 35.
Furthermore, it is desirable to limit the use of the drug container 4 so that it can be supplied to two distribution trays 35 simultaneously.

The reason for this is to shorten the waiting time of the distribution tray 35.
As shown conceptually in FIG. 8, the medicine dispensing apparatus 1 according to the present embodiment includes a right distribution tray 35R and a left distribution tray 35L.
Here, powder B in FIG. 7 is distributed by one distribution tray 35 (for example, right distribution tray 35R), and two drug containers 4 (2-1, 2-2) for storing powder B are stored in the container. It is assumed that the unit 23 is attached.
If the powder B in FIG. 7 is to be distributed by the right distribution tray 35R, the NO. The drug containers 4 belonging to the two groups are placed on one of the container placement devices 36R corresponding to the right distribution tray 35R.
Here, it is assumed that the two container mounting devices 36R1 and 36R2 corresponding to the right distribution tray 35R have NO. When two drug containers 4 (2-1, 2-2) belonging to two groups are placed and used, a spare NO. The medicine containers 4 belonging to the two groups are lost.

In the medicine dispensing device 1 of the present embodiment, since there are two distribution trays 35, the powder is distributed also on the other left side distribution tray 35L at the same time. That is, when the first prescription is input to the medicine dispensing device 1 from the outside, the first prescription is received, and the second prescription is input from the outside while the right distribution plate 35R is being distributed, The second prescription is accepted and the distribution work is performed on the left distribution tray 35L.
Here, if the powder to be distributed in the left distribution tray 35L includes the powder B of FIG. 7, there is no spare drug container 4 in the container storage unit 23, and the left distribution tray 35R is left until the distribution work is completed. It is necessary to wait for work in the distribution tray 35L. Therefore, useless waiting time occurs.
More specifically, to process another patient's prescription (eg, the first prescription described above), for example, NO. If the two drug containers 4 (2-1, 2-2) belonging to the two groups are in use on the right distribution tray 35R side, they can be used even though the other left distribution tray 35L is empty. This is because there is no medicine container 4 and the left distribution tray 35L must be kept on standby.

Therefore, it is desirable to limit so that the spare medicine container 4 remains in the container storage unit 23.
For example, it is assumed that only one medicine container 4 belonging to the same group can be placed on a plurality of container placement devices 36 corresponding to one distribution tray 35.
In other words, even when there are a plurality of container placement devices 36 corresponding to one distribution tray 35, the same container is placed in the container placement device 36 corresponding to the same distribution tray 35 during normal use. Do not install a plurality of drug containers 4 belonging to a group.
Alternatively, it is allowed to install a plurality of medicine containers 4 belonging to the same container group on a plurality of container placement devices 36 corresponding to the same distribution tray 35, but at least one medicine container 4 to which the same container group belongs is provided. The container storage unit 23 in the container placement region 12 is left.

  In the medicine dispensing apparatus 1 according to the present embodiment, when the medicine container 4 is introduced into the medicine dispensing apparatus 1 as described above, the filling amount of the powder is confirmed. Further, the prescription amount of powder and the amount of powder actually discharged from the drug container 4 are grasped by the control unit 11. Therefore, the control unit 11 knows how much powder remains in the medicine container 4.

In the medicine dispensing apparatus 1 of the present embodiment, the powder should remain in the medicine container 4, and the powder no longer falls despite the vibration table 50 continuing to vibrate, If the amount of powder drop per unit time is excessively reduced even though the vibration table 50 continues to vibrate, the vibration pattern of the vibration table 50 is automatically changed.
More specifically, when the weight of the drug container 4 is continuously monitored while vibrating the vibration table 50, the unit of the weight of the drug container 4 even though the amount H of the powder drop does not reach the desired weight. When the change per time becomes less than a certain value, the amplitude of the shaking table 50 is increased. Alternatively, the amplitude frequency is increased or decreased. If possible, add lateral amplitude or longitudinal amplitude.

There are the following two reasons why the change per unit time in the weight of the medicine container 4 is less than a constant despite the vibration table 50 being vibrated.
(1) Adherence of powder The powder adheres in the medicine container 4 or becomes a lump and cannot pass through the opening 188.
(2) Lack of powder There is no powder in the drug container 4.

Therefore, in the present embodiment, when the change per unit time in the weight of the medicine container 4 is less than a certain value despite the vibration table 50 being vibrated, the powder table 50 is first suspected and the vibration table 50 is suspected. Increase the amplitude of. If the cause is adhesion of powdered medicine, the cause may be solved by increasing the amplitude of the shaking table 50.

Even if the amplitude of the shaking table 50 is increased, if the change per unit time in the weight of the drug container 4 is less than a certain time, the shaking of the shaking table is stopped after a certain grace period, A predetermined notification is made. For example, an abnormal display is made on the operation display unit 3. Alternatively, the user is informed that an abnormality has occurred in the medicine dispensing device 1 by voice, warning sound, or light.
Then, the above-described shortage processing step is executed.

The grace time until the above-described shortage processing step is executed may be constant, but may be automatically changed according to conditions.
For example, after the shaking table 50 is vibrated, the above-mentioned grace time is lengthened until a certain amount (a small amount of about 0.5 g) of powder is discharged, and after a certain amount is discharged, the grace time. Is recommended.
If the grace time immediately after vibrating the shaking table 50 is Ta and the grace time after a certain amount is discharged is Tb, Ta is 3 times or more, more preferably 6 times or more, more preferably 10 times Tb. That's it.

Moreover, when the residual amount of powder in the medicine container 4 is below a certain level, it is recommended to shorten the grace time. When this grace time is Tc, Tc is 80% or less of Tb, more desirably 80% or less, and further desirably 50% or less.
In addition, the above-described times Ta, Tb, and Tc may be changed according to the user's preference.

In the medicine dispensing device 1 of the present embodiment, the control unit 11 knows how much powder remains in the medicine container 4.
Therefore, a shortage of powder in the drug container 4 may be expected depending on the prescription amount. That is, according to the prescription, 10 g of powder is required, but only 5 g of powder remains in the drug container 4, which may be less than the required amount.
In such a case, a message to that effect is displayed on the display device, and preparation for powdered medicine is prompted. That is, prior shortage notification is performed.
In the present embodiment, when two or more drug containers 4 belonging to the same container group are installed in the container storage unit 23 in the container arrangement region 12, the total amount in the drug containers 4 belonging to the same container group is required. Advance shortage notification is made when the quantity is not reached.
In the present embodiment, the remaining amount of powder is managed for each drug container 4 and the empty drug container 4 can be searched by a predetermined operation.

  In the embodiment described above, for the purpose of shortening the waiting time of the distribution tray 35, the container storage unit 23 is limited so that the spare medicine container 4 remains, and as an example, the medicine containers belonging to the same group. 4, only one can be placed on a plurality of container placement devices 36 corresponding to one distribution tray 35.

However, the present invention is not limited to this configuration, and medicine containers 4 belonging to the same container group are placed on a plurality of container placement devices 36 corresponding to one distribution tray 35, and the same container group is placed. It is possible that the same type of powder can be simultaneously or sequentially charged from the medicine container 4 belonging to the same into the same distribution tray 35.
For example, among the container placement devices 36R1, 36R2, and 36R3 corresponding to the right distribution tray 35R, two container placement devices 36R1 and 36R2 are connected to the NO. The drug container 4 (1-1) and the drug container 4 (1-2) belonging to one group are placed, and powder is simultaneously injected from both. The start of powder injection may be simultaneous or individual.

In addition, the medicine container 4 (1-1) is first placed on the container placement device 36R1, the discharge of the powder from the medicine container 4 (1-1) is started, and the powder is discharged from the medicine container 4 (1-1). During this time, the container moving means 28 is operated to place the medicine container 4 (1-2) on the empty container placement device 36R2, and the medicine container 4 (1-2) also discharges the powder. You may start.

  In the case where powder is loaded from a plurality of drug containers 4 belonging to the same container group to a plurality of container mounting devices 36 corresponding to one distribution tray 35, the total amount of the powder loaded from the plurality of drug containers 4 When the desired amount is reached, the vibration of the container mounting device 36 is stopped.

  Alternatively, the amount of powder discharged from each drug container 4 may be determined in advance, and the vibration of each container mounting device 36 may be stopped when a predetermined amount of powder is discharged from each drug container 4.

For example, when the required amount of powder is 40 g, the desired amount of powder 40 g is divided, and the divided value is assigned as the amount of powder to be discharged from the drug containers 4 (1-1) and 4 (1-2). For example, the desired amount 40 g of powder is divided into 10 g and 30 g, 10 g is assigned to the drug container 4 (1-1), and 30 g is assigned to the drug container 4 (1-2).
When 10 g of powder is discharged from the drug container 4 (1-1), the vibration of the container mounting device 36 R 1 is stopped, and when 30 g of powder is discharged from the drug container 4 (1-2), the container mounting device 36 R 2 is stopped. Stop vibration.

It is used only for the purpose of obtaining information.
In the present embodiment, when the medicine container 4 is carried into the medicine dispensing apparatus 100 from the outside, the weight of the medicine container 4 is measured by the weight measuring means of the container temporary placement portion 18 provided in the door portion 16. . Further, predetermined information is obtained from the medicine container 4 by the information reading means.

The container temporary placement unit 101 provided inside the housing 10 is used for measuring the amount of the medicine accommodated in the medicine container 4 when the packaging is finished and the medicine container 4 is returned to the container storage part 23. Limited.
When the packaging is completed and the drug container 4 is returned to the container storage unit 23, the drug container 4 is held by the container moving means 28, and the drug container 4 is moved and installed in the container temporary placement unit 101 in the housing 10. To do. Then, the weight of the medicine container 4 is measured. In addition, information of the RFID tag 91 attached to the medicine container 4 is rewritten.

Next, the container temporary placement parts 18 and 101 provided in the door part 16 and the housing | casing 10 are demonstrated. Since the two container temporary placement portions 18 and 101 have the same structure, the container temporary placement portion 18 provided on the door portion 16 will be described as a representative.
The container temporary placement portion 18 is attached to the door portion 16 and moves together with the door portion 16.
The container temporary placement unit 18 includes a placement table 251, an engagement lever 252, and a holding member 253. The holding member 253 has a fence shape and holds the drug container 4.
The mounting table 251 includes a backrest portion 255 and a pedestal portion 256 arranged in a substantially horizontal posture.
The backrest portion 255 has a rectangular and large installation portion 257 at the center, and rectangular side portions 258a and 258b on both sides thereof.
The side portions 258a and 258b are inclined toward the front side with respect to the installation portion 257.
There is a large notch 260 in the center of the pedestal 256.

  The engagement lever 252 is disposed in the notch portion 260 of the pedestal portion 256. The engaging lever 252 and the holding member 253 are engaged, and when the engaging lever 252 is lowered, the holding member 253 is raised.

When the drug container 4 is attached to the container temporary placement unit 18, the drug container 4 is placed on the mounting table 251 using a human hand or the container moving means 28.
When the medicine container 4 is placed on the mounting table 251, the engagement lever 252 swings and sinks, and the holding member 253 is raised instead. The holding member 253 holds the side surface of the medicine container 4. Further, the fixing iron plate part 6 side of the medicine container 4 is held by the backrest part 255 of the mounting table 251.
Therefore, the medicine container 4 is held by the pedestal portion 256 and the backrest portion 255 of the mounting table 251 and the holding member 253 and does not fall off.

In the medicine dispensing device 100, a scraping member 280 (cleaning unit) is provided at a position directly above the container temporary placement unit 18 of the door unit 16. The scraping member 280 is provided not on the door 16 but on the main body side of the medicine dispensing device 1.
A suction port 282 is opened in the scraping member 280, and the suction port 282 is connected to a suction device (not shown).

The scraping member 280 is a member provided for cleaning the side surface of the medicine container 4. In the above-described embodiment, the medicine is supplied directly from the medicine container 4 to the distribution tray 35. For this reason, after the medicine is supplied, the medicine may adhere to the side surface of the medicine container 4 due to the influence of static electricity or the like. In particular, the drug may stick to the vicinity of the opening 188 of the drug container 4.
Therefore, the side surface of the medicine container 4 is pressed against the recess 281 (container contact part) of the scraping member 280, and the medicine container 4 is slid downward or upward.
At the same time, a suction device (not shown) is activated. Therefore, even if a drug residue remains on the side surface of the drug container 4, it is cleaned by the scraping member 280.

Also in the medicine dispensing apparatus 100 of the present embodiment, there is a powder injection hopper 413 between the medicine division region 13 and the medicine packaging region 14, and the powder divided in the medicine division region 13 is supplied to the powder injection hopper 413. The medicine packaging device 53 is used for packaging.
In the medicine dispensing device 100 of the present embodiment, a hopper cleaning operation for cleaning the powder injection hopper 413 can be performed.
In the hopper cleaning operation, the cleaning agent 103 is charged into the powder charge hopper 413. The cleaning agent 103 is a release agent, and is a powder other than the prescribed medicine, and is a powder for cleaning the inside of the hopper. The cleaning agent 103 is selected so as to be harmless even if it enters a person's mouth regardless of the presence or absence of medicinal effects.
The cleaning agent 103 is, for example, powder or particles that are harmless to the human body, such as baking soda powder, lactose, and starch.
FIG. 15 is a conceptual diagram of an embodiment having a function of feeding the cleaning agent 103 into the powder feeding hopper 413 during the cleaning operation.
In the embodiment shown in FIG. 15, an opening / closing plate 416 is provided at the discharge side opening (drug discharge port) at the end of the powder injection hopper 413, and an air nozzle 422 is provided in the vicinity of the outside of the opening / closing plate 416.

The powder injection hopper 413 has a shape as shown in FIG. 21, for example, and has a discharge side opening (drug discharge port) 1000 at the lower part and an introduction side opening 1001 at the upper part. An opening / closing plate 416 is provided in the discharge side opening 1000.
A suction opening 1002 is opened on the side surface of the powder injection hopper 413. The suction opening 1002 is at least above the discharge side opening 1000 and at a height closer to the introduction side opening 1001 than the discharge side opening 1000. An extension line of the central axis XX in the planar direction of the suction opening 1002 passes through the vicinity of the central axis ZZ of the powder injection hopper 413. That is, the suction opening 1002 is provided at the center of the side surface of the powder injection hopper 413 in plan view.
The shape of the suction opening 1002 is flat, and the width is wider than the length. A pipe member 1010 such as a pipe or a hose is connected to the suction opening 1002, and the end of the pipe member 1010 is connected to the suction device 415. That is, the tube member 1010 constitutes a part of the suction path from the suction opening 1002 to the suction device 415.

In this embodiment, the pipe member 1010 has a curved portion 1012. That is, in the present embodiment, the position near the suction opening 1002 in the suction path is greatly curved. That is, when the tube member 1010 is viewed from above, a curved portion 1012 is recognized.
The suction opening 1002 is flat. Therefore, the air flow velocity in the vicinity of the suction opening 1002 is different between the side near the outside of the curve and the side near the inside.

The hopper cleaning operation performed by introducing the cleaning agent 103 is performed according to the following procedure.
As the first step, the cleaning agent 103 is introduced into the powder injection hopper 413. At this time, the opening / closing plate 416 at the end of the powder injection hopper 413 is closed.
Then, the introduction side opening 1001 of the powder injection hopper 413 is closed by the hopper closing member 400 (FIG. 18). In this state, the suction device 415 is operated. As a result, a violent air flow is generated in the powder charge hopper 413, and the cleaning agent 103 swirls vigorously and collides with the inner wall of the powder charge hopper 413.
Here, since the open / close plate 416 at the end of the powder charging hopper 413 is closed, the amount of air supplied into the powder charging hopper 413 is limited. Therefore, although the cleaning agent 103 swirls in the powder injection hopper 413, the amount of air sucked by the suction device 415 is small. Therefore, the cleaning agent 103 is merely stirred in the powder charging hopper 413 and the amount sucked out by the suction device 415 is small.
Therefore, the cleaning agent 103 stops in the powder charging hopper 413 and collides with the inner wall of the powder charging hopper 413 for a long time. Moreover, the impact of the collision is large because the centrifugal force of the cleaning agent 103 acts and hits the inner surface of the powder injection hopper 413 as if it were a cyclone type vacuum cleaner. Therefore, the medicine adhering to the inner wall of the powder charging hopper 413 is peeled off.

Thereafter, the opening / closing plate 416 at the end of the powder injection hopper 413 is opened (FIG. 19). More preferably, the opening and closing of the opening / closing plate 416 is repeated.
As a result, outside air is introduced from the end of the powder charging hopper 413 into the powder charging hopper 413, which tends to be negative pressure, and a more intense air flow is generated in the powder charging hopper 413, and the cleaning agent 103 is swirled vigorously. The drug that collides with the inner wall of the charging hopper 413 and adheres to the inner wall of the powder charging hopper 413 is peeled off.

In particular, in this embodiment, since the suction opening 1002 is flat and is a suction path, and the position immediately adjacent to the suction opening 1002 is greatly curved, the air flow rate in the vicinity of the suction opening 1002 is outside the curve. It is different between the side close to and the side close to the inside.
In the present embodiment, the air flow rate increases near the inner wall 1003, and the air flow rate decreases near the opposing inner wall 1006.
Therefore, a strong swirl flow is generated in the powder injection hopper 413. In addition, air is introduced from a discharge-side opening 1000 provided in the lower part of the powder injection hopper 413. Therefore, the air flow advances from the lower side to the upper side with the swirling along the inner wall of the powder injection hopper 413. Therefore, the charged cleaning agent 103 scrapes the inner wall of the powder injection hopper 413 to remove the drug, rolls it together with the cleaning agent 103, and discharges it by the suction device 415.
In this embodiment, since the suction opening 1002 is provided in the vicinity of the upper end of the powder charging hopper 413, almost all the inner walls of the powder charging hopper 413 are cleaned.

The peeled medicine is sucked out together with the cleaning agent 103 by the suction device 415 and discharged out of the powder injection hopper 413.
When the opening and closing of the opening / closing plate 416 is repeated, the cleaning agent 103 is stirred while the cleaning agent 103 is stopped by the powder injection hopper 413 and the cleaning agent 103 is discharged while introducing a part of the cleaning agent 103 by introducing air. Stirring is repeated.

Further, the drug attached to the outer surface of the opening / closing plate 416 itself is removed by blowing air from an air nozzle 422 provided in the vicinity of the opening / closing plate 416 (FIG. 20).
That is, according to the experience of the present inventors, the medicine may adhere to the opening / closing plate 416 provided in the discharge side opening 1000 of the powder injection hopper 413. Here, the inner side of the opening / closing plate 416 (the inner surface side of the powder injection hopper 413) can be cleaned by using the above-described impact of the cleaning agent 103, but the outer surface of the opening / closing plate 416 itself is the cleaning agent 103. Can not collide.
Therefore, in this embodiment, air is blown directly from the air nozzle 422 provided in the vicinity of the opening / closing plate 416 toward the outside of the opening / closing plate 416 (FIG. 20), and the drug attached to the outside of the opening / closing plate 416 is removed. .

In addition, since the opening / closing plate 416 is provided at a deep position in the normal apparatus, it is difficult to apply the injected air when the opening / closing plate 416 closes the discharge-side opening 1000. Therefore, in the present embodiment, the air nozzle 422 is provided at a position where the jetted air hits when the opening / closing plate 416 is in the open position.
Further, since there is a wrapping paper in the vicinity of the opening / closing plate 416, the medicine separated by air is collected in the wrapping paper.
A series of operations will be described together. The cleaning agent 103 is charged into the powder injection hopper 413 to start suction, and the opening / closing plate 416 starts to be opened and closed in the latter half of the suction. At that time, the opening / closing plate 416 is opened from the air nozzle 422. Blow the air directly toward the outside. Stop suction and air after 5-10 seconds.

When carrying out the hopper cleaning operation, the cleaning agent 103 is introduced into the powder injection hopper 413, but the method of introducing the cleaning agent 103 is arbitrary.
For example, the cleaning agent 103 may be put into the powder injection hopper 413 directly by an operator. Further, a dedicated cleaning agent charging device may be provided in the vicinity of the introduction side opening 1000, and the cleaning agent 103 may be charged into the powder injection hopper 413 from the cleaning agent charging device.
Alternatively, the cleaning agent 103 may be charged into the powder charging hopper 413 using the drug container 4.
For example, a specific drug container 4 is filled with a cleaning agent 103 such as baking soda and stored in the container storage unit 23 in the same manner as other drug containers 4.
Then, the cleaning agent 103 in the medicine container 4 is put into the powder charging hopper 413 by an operation according to the operation of taking out the powder from the normal medicine container 4 and putting it in the powder charging hopper 35.

More specifically, the cleaning agent 103 is filled automatically or manually when a medicine requiring cleaning is packaged, or when the powder injection hopper 413 is found to be contaminated by a residual medicine sensor or the like. The drug container 4 is selected.
Then, the medicine container 4 is held by the container moving means 28, the medicine container 4 is moved, and the medicine container 4 filled with the cleaning agent 103 is placed on the container placing device 36.
Thereafter, the container mounting device 36 is vibrated to put the cleaning agent 103 into the distribution tray 35 from the medicine container 4. Then, the cleaning agent 103 is discharged from the distribution tray 35 by the scraping device 37 and is put into the powder injection hopper 413.

Here, in the hopper cleaning operation, unlike the case of a normal powder packaging operation, the dispensing dish 35 is not rotated when the cleaning agent 103 is put into the dispensing dish 35 from the medicine container 4.
Referring to FIG. 16, as shown in FIG. 16A, the distribution tray 35 is stopped, the container mounting device 36 is vibrated, and the cleaning agent 103 is put into the distribution tray 35 from the medicine container 4. As a result, as shown in FIG. 16A, the cleaning agent 103 rises in one place of the distribution dish 35.
Note that the input amount of the cleaning agent 103 (the discharge amount from the medicine container 4) is not as strict as in the case of prescription, but rather priority is given to a short time required for input. For example, the amount of cleaning agent 103 (for example, about 8 grams) required for cleaning is discharged from the medicine container 4 in as short a time as possible.
Thereafter, as shown in FIG. 16 (b), the distribution tray 35 is rotated to bring the crest of the cleaning agent 103 closer to the vicinity of the scraping device 37.
Then, as shown in FIG. 16C, the scraping device 37 is driven, and the cleaning agent 103 is discharged from the distribution tray 35 and put into the powder injection hopper 413.

  According to this aspect, the time required for the hopper cleaning operation can be shortened. However, the present invention is not limited to this configuration, and the distribution dish 35 is rotated at a constant rotational speed so that the cleaning agent 103 is evenly distributed on the distribution dish 35 as in the case of normal powder packaging operation. May be.

  As another aspect, as shown in FIG. 22, a container mounting device 36 limited to the purpose of discharging the cleaning agent 103 is provided in the vicinity of the powder injection hopper 413, and the powder injection hopper 413 is cleaned without the distribution tray 35. The agent 103 may be added.

In the configuration shown in FIG. 22, the container mounting device 36 and the cleaning / cleaning agent temporary storage container 440 are provided in the vicinity of the powder injection hopper 413. The cleaning agent temporary storage container 440 can be turned over by a reversing mechanism (not shown). Moreover, the cleaning agent temporary storage container 440 may open and close at the bottom.
In the present embodiment, the drug container 4 is always installed in the container mounting device 36, and the drug container 4 is filled with a sufficient amount of the cleaning agent 103. Then, a predetermined amount of the cleaning agent 103 is discharged from the medicine container 4 in advance, and the cleaning agent 103 for one cleaning is stored in the temporary cleaning agent storage container 440. As shown in FIG. Wait on top.
When it is time to clean the powder charging hopper 413, the cleaning agent temporary storage container 440 is turned over by an inversion mechanism (not shown) as shown in FIG. 22B, and the stored cleaning agent 103 is charged into the powder charging hopper 413. Thereafter, the process is the same as that described above, and the inlet side opening 1001 of the powder injection hopper 413 is closed by the hopper closing member 400 and the inner wall of the powder injection hopper 413 is operated by operating the suction device 415 as shown in FIG. Clean.

Next, other functions that should be specially described will be described.
The medicine dispensing devices 1 and 100, like the known one, disperse the powder 445 evenly in the medicine loading grooves 32 of the distribution tray 35 as shown in FIG. 23A, and the scraping device 37 as shown in FIG. The scraping disk 446 is dropped into the chemical introduction groove 32 of the distribution tray 35. After that, the distribution tray 35 is rotated in the direction of the arrow by an angle corresponding to the number of distributions, and the powder 445 distributed in the drug insertion groove 32 in the rotation range as shown in FIG. 23C is placed in front of the scraping disk 446. Gather together.
Then, the scraping disk 446 is rotated, and the powder 445 in the area collected as shown in FIG.
Thereafter, this division / scraping process is repeated, and all of the powder 445 dispersed in the distribution tray 35 is discharged.

Here, in the medicine dispensing devices 1 and 100 of the present embodiment, the distribution tray 35 is rotated over a wider angle than in the case of the previous division / scraping stroke only during the final division / scraping stroke.
Hereinafter, the reason will be described.
As described above, as shown in FIG. 23A, the powder 445 is evenly distributed in the medicine charging groove 32 of the distribution tray 35, and as shown in FIG. 23B, the scraping disk 446 of the scraping device 37 is disposed in the distribution tray. When dropped into the 35 chemical charging grooves 32, the continuously distributed powder 445 is partitioned by the wall of the scraping disk 446.

When the distribution tray 35 is rotated, as shown in FIG. 23C, the powder 445 distributed in the drug introduction groove 32 in the rotation range is collected by the scraping disk 446, but the remaining powder 445 was supported as if. The situation is as if the wall has disappeared, and some of the powder 447 collapses, and the scraped disc 446 spills into the advanced region.
Therefore, in this embodiment, during the final division / scraping process, the distribution tray 35 is rotated beyond the position 448 where the scraping disk 446 is first inserted as shown in FIG. The powder 447 that spreads out is collected.
That is, in this embodiment, after the distribution tray 35 is rotated once (360 degrees), the distribution tray 35 is further rotated from the one-round position 448 by an additional angle + θ (plus theta).

Furthermore, in the medicine dispensing devices 1 and 100 of this embodiment, the additional angle + θ (plus theta) is automatically changed according to the properties of the powder 445.
Here, the properties of powder 445, which are factors that determine the additional angle + θ (plus theta), are the ease of spreading of powder, fluidity, viscosity, and the like, and vary depending on the particle size and stickiness.
For example, the fluidity of powder and the ease of discharge from the drug container 4 are tested in advance, and all powders are divided into a plurality of stages. This is called, for example, “flow coefficient”, and powder is divided into a flow coefficient 1 to a flow coefficient 8.

For example, the smaller the flow coefficient, the higher the fluidity and the easier it is to spread. For example, if the flow coefficient is 5, it is a powder that tends to harden, the amount of collapse is small, and it is difficult to spread. Therefore, the additional angle + θ is limited to a narrow range of about 1/9 round (40 degrees). On the other hand, if the flow coefficient is 2, the powder tends to collapse and tends to spread widely, so the additional angle + θ is set to a wide angle of about 1/6 round (60 degrees).
Therefore, according to the medicine dispensing devices 1 and 100 of the present embodiment, the spread powder 447 can be reliably collected, and the distribution tray 35 does not rotate to a useless range, so that the efficiency is high. Therefore, the time required for the entire series of strokes can be shortened.

Further, as described above, the medicine dispensing devices 1 and 100 are provided with the medicine packaging device 53 and the printing means in the medicine packaging area 14, and the powder supplied from the medicine division area 13 is taken by the sealing device one by one. Seal and package. Then, as shown in FIG. 25, a single dose of powder is packaged in a bag shape, and the individual package 451 is discharged as a drug packaging band 452 connected in a band shape.
In addition, as described above, the medicine dispensing apparatus 1, 100 according to the present embodiment includes printing means and can print predetermined information on the packaging bag.
For example, as shown in FIG. 25, the name of the user and the usage are printed on each individual package 451. In addition, a dispensing record 453 is described at the end of the medicine packaging band 452.
For example, when the powder is normally distributed, “normal” is printed as shown in FIG.
On the other hand, if any abnormality occurs when distributing powder, for example, as shown in FIG. 25 (a), “allocation abnormality” is printed, and a warning display notifying that some trouble has occurred. Printed.

Furthermore, the medicine dispensing devices 1 and 100 of the present embodiment can print not only black but also multi-colors such as red and blue as well as lines and marks. The method of performing multi-color printing is not limited. For example, a multi-color display provided with a large number of ink nozzles and ink application bodies (such as a pen tip), a transfer paper of different colors, and a transfer paper It may be of a structure that automatically changes and changes color.
In the medicine dispensing devices 1 and 100 of the present embodiment, if any abnormality occurs when distributing powder, for example, a dispensing record is printed in a conspicuous color such as red, or under a letter or part of a bag. Conspicuous color marks and lines are added.
In the present embodiment, a red line 455 is added under the characters “distribution abnormality”.

The cause of the occurrence of the “distribution abnormality” is, for example, that vibration is applied to the medicine dispensing devices 1 and 100, and a lot of powder is temporarily discharged from the medicine container 4 or the container placement device 36 is not vibrated. It may seem that it was stable.
Further, in the medicine dispensing apparatuses 1 and 100 of the present embodiment, when distribution abnormality occurs, the fact is displayed on the operation display unit 3.
Here, since the display of the operation display unit 3 is generally changed by a predetermined operation, the pharmacist or the like may not notice. However, according to the present embodiment, an abnormality is displayed on the discharged medicine wrapping band 452, and since the device is further conspicuous, an abnormality is noticed by inspection before handing over the individual wrapping 451 to the patient. It will be.

In the medicine dispensing devices 1 and 100 of the present embodiment, for example, if any abnormality occurs, for example, the prescription ID is stored in the storage unit of the control device, and the dispensing record corresponding to the prescription ID is packaged. A particular color is attached to the to make it stand out. In this way, the occurrence of abnormality and the medicine packaging can be associated.
The portion printed in red or the like is not limited to the end of the medicine packaging band 452, but may be the medicine packaging band 452, may be an intermediate portion, or may be an individual individual packaging 451. .

As described above, in the medicine dispensing device 1, 100 of this embodiment, the medicine container 4 is installed in the container placement device 36 and a predetermined amount of medicine is put into the distribution tray 35, and then the container placement device 36 has the medicine placement device 36. The weight of the drug container 4 is confirmed by the weight measuring means 52. In addition, the weight of the medicine container 4 is reconfirmed by the container temporary placement units 18 and 101. Thus, although the weight measurement of the medicine container 4 after medicine discharge is performed at a plurality of locations, it is desirable to perform the measurement at a plurality of times at each measurement location.
The allowable amount of the drug container 4 has an upper limit and a lower limit. If it is within the upper limit or the lower limit and is close to the upper limit or the lower limit, the weight measurement of the drug container 4 is performed again just in case. It is desirable to do.
Similarly, when the upper limit or lower limit is exceeded, a warning operation is performed on the system, and a warning is displayed on the operation display unit 3 or the like. In consideration of the influence of minute vibrations at the time, it is desirable not to execute the warning operation immediately but to measure the weight of the medicine container 4 again.
