Therefore, the electromagnet does not generate heat, and the medicine in the medicine container is not heated. Further, since it is not necessary to energize the electromagnet while the drug container is fixed to the vibration table, power consumption is small. As a result, the power consumption of the entire drug delivery device is small, and the heat generation is small, so that the drug is less likely to be affected.

The weight measuring means measures the original weight of the drug container before the drug is discharged, and the weight measuring means monitors the weight of the drug container when the powdered drug is discharged little by little from the drug container. It is preferable to have a weighing function for stopping discharge of the powder medicine from the drug container when the current weight, which is the weight of the drug container, matches or substantially matches the value obtained by subtracting the target discharge amount from the original weight. As to the means for measuring the weight of the medicine container, it does not matter whether the weight of the medicine container is measured directly or indirectly. That is, only the weight of the drug container may be measured directly, or the weight including a device such as a shaking table may be measured. According to this configuration, the original weight, which is the weight of the drug container before discharging the drug, and the current weight, which is the current weight of the drug container, are used, and the current weight matches the value obtained by subtracting the target discharge amount from the original weight. Stop the vibration of the shaking table immediately. Alternatively, taking into account the weight of the medicine in the middle of falling, the vibration of the shaking table is stopped when the current weight is slightly less than the value obtained by subtracting the target discharge amount from the original weight, and substantially coincides with it. Therefore, after the target amount of medicine is discharged, the vibration of the shaking table is stopped and the discharge of the medicine is stopped.

The means temporarily adjusts the posture of the drug container so that the drug discharge portion is higher than the posture immediately before taking out the prescribed drug container from the container storage device and placing it on the container placing device. It is preferable to perform a changing attitude change operation. In this configuration, it is assumed that when the drug container is moved, the drug container is transported in a lateral posture (a posture in which the drug ejection portion is oriented sideways). For example, even if the storage posture of the drug container in the container storage device is vertical and the drug discharge part is originally on the top, the drug container is placed in a horizontal position (the drug discharge part faces sideways) due to the layout restrictions of the device. posture) to transport the drug container. Therefore, in this configuration, an attitude changing operation is performed to once change the attitude of the medicine container so that the medicine discharge part faces upward before the medicine container is taken out and placed on the container placing device. More specifically, compared to before the start of the attitude change operation, the medicine ejection part is tilted to face obliquely upward, and the medicine near the ejection part is biased toward the rear of the medicine container (in the direction opposite to the ejection part). Let By doing so, the medicine in the medicine container is moved to the side away from the medicine discharge part.

It is preferable to develop the magnetic force to hold the drug container after closing the lid. It is desirable that the container moving means has a function of opening and closing the opening/closing lid, and the opening/closing lid is closed by the container moving means, but the container placing device may have the function of opening/closing the opening/closing lid. Moreover, you may have the opening-and-closing lid apparatus independent of these. With this arrangement, the medicine in the medicine container will not spill out when the medicine container is removed from the container placing device. That is, after a predetermined amount of medicine has been dispensed and before the open/close lid is closed, if the magnetic force of the container moving means is exerted, the medicine remaining near the discharge portion will spill out due to the vibration of adsorption. On the other hand, if the magnetic force of the container moving means is exerted after closing the opening/closing cover as in the present invention and the medicine container is attracted to the container moving means side, the medicine inside will not spill out.

The whole or part of the drug container is covered with a housing, the housing has a door so that the drug container can be put in and taken out from the inside, the door has a drug container temporary placement part, and the drug container is provided in the vicinity of the door.

In this embodiment, the safety device is released by closing the door portion 9, so that the container moving means 700 and the like can operate.
When the weighing by the weight measuring means 19 and the reading of information by the information reading means 16 are finished, the container moving means 700 is operated, and the hand portion 707 of the container moving means 700 approaches the drug container temporary placement portion 11 to The part 707 is pressed against the medicine container 2 . Then, the carrying iron plate portion 157 provided on the medicine container 2 is attracted by the magnet provided on the hand portion 707 .

Thereafter, the hand portion 707 is retracted to pull the drug container 2 away from the drug container temporary placement portion 11 of the door portion 9 , and the arm members 705 and 706 are moved to move the hand portion 707 to any container setting portion of the drum member 102 . 103.
Then, while rotating the wrist portion 708 of the hand portion 707 horizontally, the drum member 102 is rotated to cause the drug container 2 to face the specific container setting portion 103 . That is, the hand portion 707 and the drum member 102 are rotated in opposite directions as if two gears are meshing with each other (FIGS. 15 and 16), and the medicine container 2 is made to face the specific container setting portion 103. FIG. Thereafter, the arm members 705 and 706 are operated to push the drug container 2 into the container mounting portion 103 of the drum member 102 to engage the drug container 2 with the container mounting portion 103 . When the medicine container 2 is attached in the correct posture, the protruding member (attachment detection member 322 ) is retracted into the drum member 102 . A protruding member detection sensor 333 provided in the drum member 102 detects whether or not the drug container 2 is attached in a proper posture.
Furthermore, after that, the magnetic force of the hand portion 707 is eliminated, and the hand portion 707 is separated from the medicine container 2 . The position where the drug container 2 is attached is stored in the control device.
By repeating this operation, a considerable number of drug containers 2 are installed on the drum member 102 .

In the drug delivery device 1 of the present embodiment, the drum member 102 is rotated at a predetermined timing, and the location of the drug container 2 and the type of drug contained therein are confirmed.
That is, in the medicine dispensing device 1 of this embodiment, as shown in FIG. 11, one information reading device 335 (information reading means) is provided corresponding to each stage, and the number of information reading devices 335 varies depending on the number of containers installed. less than the number of units 103;
The drug dispensing device 1 of the present embodiment employs a configuration in which the information reading device 335 provided near the drum member 102 reads drug information from the information recording member 15 of each drug container 2 while rotating the drum member 102 . As a result, the number of information reading devices 335 to be attached is reduced.

Further, in the drug dispensing device 1 of the present embodiment, the drum member 102 is rotated at a predetermined timing, and the posture of the drug container 2 is confirmed. That is, in the medicine dispensing device 1 of this embodiment, one protruding member detection sensor 333 (FIG. 15) is provided in the drum member 102 corresponding to each stage, and the number of the protruding member detection sensors 333 is equal to that of the container. The number is smaller than the number of installation units 103 .
In the drug dispensing device 1 of the present embodiment, while rotating the drum member 102, the protruding member detection sensor 333 confirms the protruding state of the mounting detection member 322 (FIGS. 12 and 15). 333 mounting number is reduced.
At the same time, it is confirmed whether or not there is a drug container 2 protruding from the normal position by the protruding detection sensor 330 (FIG. 11) provided on the outside.

Possible timings for rotating the drum member 102 include, for example, immediately after the power is turned on, before the start of work for the day, before each sorting work, at regular intervals, and immediately after the door 9 of the housing 7 is closed.

Further, the drug delivery device 1 of this embodiment automatically selects the drug container 2 according to the prescription. Specifically, the drum member 102 of the container storage device 101 is rotated to bring the desired drug container 2 closer to the container moving means 700 . Then, the drug container 2 is held by the hand portion 707 of the container moving means 700 . That is, the hand portion 707 of the container moving means 700 approaches the container setting portion 103 of the drum member 102 and presses the hand portion 707 against the drug container 2 . Then, the carrying iron plate portion 157 provided on the drug container 2 is attracted by the magnet provided on the hand portion 707 .
Then, the arm members 705 and 706 are retracted to extract the medicine container 2 , and the arm members 705 and 706 are operated to set the medicine container 2 on the vibration table 20 of the container placing device 3 .
When a plurality of drugs are mixed and enclosed in one package, a plurality of drug containers 2 are installed on the container placing device 3 .
Further, in this embodiment, since the information reading means 27 (FIG. 17) is provided near the container placing device 3, the type of medicine contained in the medicine container 2 is confirmed by the information reading means 27. . That is, the type of drug in the drug container 2 recorded on the information recording member 15 is read by the information reading means 27 .
Then, the vibration table 20 (FIG. 3) is vibrated. As a result, the powdered medicine in the medicine container 2 moves slowly, is ejected from the medicine container 2 and falls on the distribution tray 201 .

That is, when the vibration table 20 starts vibrating, the drug container 2 vibrates. Here, in this embodiment, the drug container 2 is firmly joined to the vibration table 20 by the permanent magnets of the self-holding solenoids 30a and 30b (FIG. 7), and the degree of close contact with the vibration table 20 is high. The medicine container 2 vibrates at the same frequency as the vibrating table 20 . As a result, as shown in FIG. 6, the powdered medicine stored in the powdered medicine storing portion 17 of the medicine container 2 slowly moves toward the medicine discharge portion 8 side. The self-holding solenoids 30a, 30b function as container holding means.
In addition, before and after the start of vibration, the distribution plate 201 of the powder medicine distribution device 202 is rotated. Before and after the start of vibration, the weight of the drug container 2 is measured. The weight of the drug container 2 is monitored while the drug container 2 is being vibrated, and the vibration of the shaking table 20 is stopped when the total drop amount of the powder drug reaches the desired weight.

The weight of the drug container 2 is obtained by subtracting a certain value from the weight detected by the weight measuring means 25 (FIG. 8). More specifically, the weight of the medicine container 2 is obtained by subtracting the weight of the members above the weight measuring means 25 of the container placing device 3 from the weight detected by the weight measuring means 25 .
The weight of the drug container 2 immediately after being placed on the shaking table 20 is stored as the original weight G. Also, the weight of the drug container 2 is constantly monitored. That is, the current weight of the medicine container 2 is monitored as the current weight g.

More specifically, whether the powdered medicine is falling is confirmed by the weight of the medicine container 2 decreasing. That is, in this embodiment, the current weight (current weight g) of the drug container 2 is continuously monitored by the weight measuring means 25 even while the powdered drug is falling from the drug discharge portion 8 of the drug container 2 . The original weight G of the medicine container 2 immediately after being placed on the shaking table 20 is compared with the current weight g, and the drop amount H (G minus g) of the powdered medicine is constantly calculated.
The vibration of the shaking table 20 is stopped when the total drop amount H of the powder medicine reaches a desired weight.
That is, when the current weight g of the medicine container 2 measured by the weight measuring means 25 becomes smaller than the original weight G measured by the weight measuring means 25 before the start of the vibration by a desired weight, the vibration of the shaking table 20 is stopped. .
Moreover, it is desirable to reduce the amplitude of the vibration table 20 and lower the vibration frequency before stopping the vibration of the vibration table 20 .
For example, when the current amount of powdered medicine discharged is the amount obtained by subtracting several grams from the final amount of powdered medicine discharged (target discharge amount), the amplitude of the shaking table 20 is reduced and the vibration frequency is lowered. drive in a tight state. Then, the remaining several grams are discharged while reducing the amplitude of the vibration table 20 and lowering the vibration frequency.
Then, as described above, the vibration of the shaking table 20 is stopped when the total dropping amount H of the powder medicine reaches the desired weight.
After that, the container moving means 700 automatically operates to return the drug container 2 to the drum member 102 in the drug shelf area 100 .

As described above, when the total drop amount of the powder medicine reaches the desired weight, the vibration of the vibration table 20 is stopped, and then the rotation of the distribution plate 201 is stopped. Then, the motor 950 (FIG. 21) is rotated forward to swing the scraping arm 931, lowering the tip side to lower the scraping mechanism 606, and moving the scraping mechanism 606 into the medicine feeding groove 208 of the distribution plate 201. put in
Further, the distribution plate 201 is rotated by an angle corresponding to the number of distributions, and is scraped onto the scraping plate 609 . Thereafter, the motor is reversely rotated to rotate the scraping plate 609 , and the drug is scooped up by the scraping plate 607 to be discharged from the distribution plate 201 and introduced into the drug introduction opening 241 .
The drug introduced into the drug introduction opening 241 drops down the powdered drug introduction hopper 413 and is transported to the drug packaging device 410 and packaged by the drug packaging device 410 .
This operation is sequentially repeated to discharge all the medicines in the distribution tray 201 and pack them in the medicine packaging device 410 respectively.
In parallel with this, the container moving means 700 is activated, and the drug container 2 is returned to the container setting portion 103 of the drum member 102 .

That is, when a series of ejection steps is completed, the electromagnet is deenergized and the container moving means 700 is operated to return the drug container 2 to its original position.
Here, as a unique configuration of the drug dispensing device 1 of this embodiment, when the container moving means 700 is operated to return the drug container 2 to its original position, the total weight of the drug container 2 is weighed again. More specifically, when the drug container 2 is returned to its original position, the drug container 2 is once carried to the drug container temporary placement section 11 , and the drug container 2 is weighed by the weight measuring means 19 provided in the drug container temporary placement section 11 . , and the total weight of the drug container 2 is weighed again.

Then, the total weight of the medicine container 2 at the beginning (immediately before the medicine is discharged this time) is compared with the total weight of the medicine container 2 after the medicine is discharged. Confirm that the difference between the two agrees with the dispensed amount of the drug discharged during the above steps. That is, a step of confirming the amount of discharge is carried out.
Alternatively, the weight of the drug container 2 measured by the weight measuring means 19 provided in the drug container temporary placement unit 11 is compared with the weight of the drug container 2 after discharging the drug measured by the drug feeder 50 (powder drug loading device), Make sure they match. That is, an inspection step is performed to determine whether or not the weight measuring means 25 of the drug feeder 50 is accurate.
Then, if the total weight of the drug container 2 is normal as a result of reweighing the total weight of the drug container 2, the container moving means 700 is operated to return the drug container 2 to its original position. If there is an abnormality in the total weight of the drug container 2, an alarm is immediately issued to notify the pharmacist.
The medicine dispensing device 1 of this embodiment has a plurality of weight measuring means, discharges the powdered medicine from the medicine container 2, and then measures the weight of the medicine feeder 50 (container placing device 3) other than the weight measuring means 25. A double weighing step of measuring the weight of the drug container 2 again is performed by the means 19 .

In the drug delivery device 1 of this embodiment, the above operations are repeated to carry out weighing, division, packaging, and cleaning of the drug.
Further, the medicine dispenser 1 of this embodiment has a function of automatically replacing the medicine container 2 as a unique operation.
That is, the drug container 2 is installed in the container installation portion 103 of the drum member 102 at a predetermined position, and the installation position of the drug container 2 is automatically changed according to the frequency of use of the drug container 2 .

For example, during periods when influenza is prevalent or when cedar pollen is scattered, the amount of consumption of specific medicines increases significantly.
In such a situation, the location of the drug container 2 is automatically changed. That is, in this embodiment, a drum-shaped storage device is adopted. In the drug dispensing device 1 of this embodiment, the drum member 102 is above the distribution plate 201, and the container moving means 700 transports the drug container 2 by vertically moving it.
On the other hand, the drum member 102 is provided with container installation portions 103 in three stages, and there is a difference in the height of the installation locations, and the moving distance of the container moving means 700 varies depending on the installation locations. That is, since the lower side is close to the distribution tray 201, the movement distance is short, and the upper side is far from the distribution tray 201, so the movement distance is long.

Therefore, the drug dispensing device 1 of the present embodiment checks the frequency of use of the drug container 2 within a certain period of time, and moves the drug container 2 with the highest use frequency to the lower side.
If there is a vacancy in the container installation section 103 provided on the lower side, the frequently used medicine container 2 in the container installation section 103 on the upper side is moved directly to the lower side.
If there is no vacancy in the container installation section 103 provided on the lower side, the drug container 2 attached to the container installation section 103 on the lower side is once installed in another place, and an empty space is made on the lower side. make. For example, the drug container 2 on the lower side is temporarily placed in the drug container temporary placement portion 11 provided on the door portion 9 to create a space on the lower side.

Further, the drug dispensing device 1 of this embodiment has a testing function for testing whether or not the weight measuring means 25 is accurate.
For example, a weight member having a known weight is prepared, and the weight is set on the container mounting portion 103 of the drum member 102 . Then, the weight member is moved to the vibration table 20 by the robot 702 or the like, and the weight of the weight member is measured by the weight measuring means 25 . If the measured value matches the weight of the weight, the weight measuring means 25 is correct, and if not, the weight measuring means 25 is defective.
The drug container 2 itself can also be used as the weight member. For example, the drug container 2 is filled with harmless powder or granules, and its weight is measured in advance. The drug container 2 used as a weight member is installed in the drug shelf area 100 or the like together with the other drug containers 2 . Then, if necessary, the robot 702 or the like moves the drug container 2 for the weight and installs it on the vibration table 20, and the weight measuring means 25 is calibrated.
In addition, in the drug dispensing device 1 of the present embodiment, the drug container 2 is measured by one weight measuring means 25, then the drug container 2 is transferred to another weight measuring means 19 by the container moving means 700, and the drug container 2 is weighed again. A calibration operation can be performed to measure the weight of the

As described above, in this embodiment, the vibrating table 20 is vibrated to discharge the powdered medicine from the drug container 2 and drop it onto the distribution tray 201. However, the powdered medicine is not discharged even though the vibrating table 20 continues to vibrate. When the powder does not drop anymore, or when the amount of powder falling per unit time becomes excessively small even though the shaking table 20 continues to vibrate, the vibration pattern of the shaking table 20 is changed. is automatically changed.
Specifically, when the weight of the drug container 2 is continuously monitored while vibrating the vibration table 20, the unit of the weight of the drug container 2 is determined even though the falling amount H of the powdered drug does not reach the desired weight. When the change per time becomes less than a constant, the amplitude of the shaking table 20 is increased. Or increase or decrease the frequency of the amplitude. Also, if possible, add transverse and longitudinal amplitudes.

There are two reasons why the change in the weight of the drug container 2 per unit time is less than constant even though the vibration table 20 is being vibrated.
(1) Adhesion of Powdered Medicine The powdered medicine adheres in the medicine container 2 or clumps together. I can't pass through certain areas.
(2) Lack of powdered medicine There is no powdered medicine in the medicine container 2 .

Therefore, in the present embodiment, when the change in the weight of the drug container 2 per unit time is less than a certain amount even though the vibration table 20 is being vibrated, sticking of the powdered medicine is first suspected, and the vibration table 20 is increase the amplitude of If the cause is sticking of the powdered medicine, the cause may be eliminated by increasing the amplitude of the vibration table 20 .

Even if the amplitude of the vibration table 20 is increased, if the change in the weight of the medicine container 2 per unit time is less than a certain amount, the vibration of the vibration table 20 is stopped and a predetermined notification is given to the user. done. For example, an abnormal display is made on a display device (not shown). Alternatively, the user is notified that an abnormality has occurred in the medicine dispensing device 1 by means of voice, alarm sound, or light.
Then, a predetermined out-of-stock processing step is executed.
In the out-of-stock processing step, the weight of the drug that has already been discharged from the drug container 2 is stored. The user, knowing that an abnormality has occurred, takes out the drug container 2 manually or by using the container moving means 700, and inspects it.

In this embodiment, the drug container 2 is taken out using the container moving means 700 in the out-of-stock processing step. That is, even if the amplitude is increased, the vibration of the vibration table 20 is stopped if the change in the weight of the drug container 2 per unit time is less than a certain amount. Then, the container moving means 700 automatically operates to move the drug container 2 to the drug container temporary placement portion 11 provided on the door portion 9 .
The user opens the door portion 9 , takes out the drug container 2 , and inspects the inside of the drug container 2 . If there is no powder medicine in the medicine container 2, the medicine container 2 is replenished with medicine. In addition, if the powdered medicine is clumped in the medicine container 2, the clump is crushed.

Thereafter, the drug container 2 is placed on the drug container temporary placement portion 11 of the opened door portion 9, and an input device, placement confirmation device, or the like (not shown) is used to notify the device that the drug container 2 has been placed. A drug container 2 is introduced into the drug dispensing device 1 . Then, manually or by using the container moving means 700, the drug container 2 is again placed on the container placing device 3, and the vibrating table 20 and the distribution plate 201 are restarted automatically or manually. In this embodiment, the drug container 2 is placed in the drug container temporary placement section 11 provided with the door portion 9, and by performing a predetermined operation, the container moving means 700 operates, and the drug container 2 is moved to the container placing device. Carry to 3.
As described above, since the weight of the medicine discharged from the medicine container 2 is stored until the operation is interrupted, powdered medicine is discharged from the medicine container 2 by the remaining discharge amount.

The medicine dispensing device 1 of this embodiment receives prescription information from an input device or communication means (not shown), and dispenses a prescribed medicine according to the prescription information. Prescription information is stored in a memory (not shown), and drug dispensing work is performed sequentially.

For example, prescription information for 20 people is input and stored in a memory (not shown). Here, summarizing the stocked prescription information, there is a case where the quantity of the drug stored in the container storage device 101 is insufficient.
For example, assume that 200 g of antipyretic agent A is stored in a specific drug container 2 attached to container storage device 101 .
However, for example, there are many prescriptions containing antipyretics due to the epidemic of influenza, etc., and the total amount of prescriptions for each patient may exceed the amount of antipyretic A stored in the medicine container 2 . In such a case, an informing means (not shown) informs that the medicine is likely to run short, and prompts the user to replenish the medicine. By replenishing the medicine, interruption of the operation of discharging the powdered medicine from the medicine container 2 can be prevented.

Further, when analyzing the stocked prescription information, there are cases where drugs that are not stored in the container storage device 101 (hereinafter referred to as unaccommodated drugs) are prescribed.
That is, a large number of drug containers 2 can be stored in the container storage device 101, and many types of drugs are held in the drug delivery device 1. However, there are cases where drugs that are not contained (non-contained drugs) are prescribed.
Even in such a case, a notifying means (not shown) is used to indicate that the unaccompanied medicine is being prescribed.

One end (upper end) of the coil spring 942 is engaged with the convex portion 944b of the spring mounting portion 944, and the coil spring 942 is mounted on the spring mounting portion 944. As shown in FIG. The other end (lower end) of the coil spring 942 is attached to the mounting member 945 in engagement with a protrusion 946 of the mounting member 945 which will be described later.

As shown in FIG. 23 , the scraping side power transmission system 932 has a gear 628 attached to a drive shaft 950 a of a motor 950 . In this embodiment, power is transmitted from the motor 950 to the gear train composed of the gears 628 , 641 , 633 , and further power is transmitted from the gear 633 to the driving side pulley 623 via the shaft member 614 . Power is transmitted from the driving side pulley 623 to the driven side pulley 682 via the toothed belt 634 .
That is, in this embodiment, the scraping-side power transmission system 932 includes a gear train composed of gears 628, 641, 633, a shaft member 614, a drive-side pulley 623, a toothed belt 634, a driven-side pulley 682, a shaft member 615. A one-way clutch may be provided on gear 641 to prevent reverse rotation of scraping mechanism 606 .

The arm-side power transmission system 933 has a motor 960, a positioning mechanism 961, and a swing mechanism 962, as shown in FIG.

Motor 960 is a motor different from motor 950 . That is, the motor 960 is a motor that drives only the arm-side power transmission system 933, and can be rotationally driven in the forward direction and the reverse direction. A drive shaft 960a of the motor 960 is mounted with a gear 951 (pinion).

The positioning mechanism 961 has a positioning pin 952 , guide members 953 a and 953 b , a connecting member 954 and a fixed side engaging member 670 .

The positioning pin 952 is a rod-shaped member, and has a rack portion 955 formed on the side surface of the cylinder. The tip side of the positioning pin 952 is tapered like a pencil. A tapered tip portion of the positioning pin 952 can engage with a groove 672 of a fixed-side engaging member 670 installed on the outside of the turntable 604 .
A positioning pin 952 is arranged on the turntable 604 . The positioning pin 952 is perpendicular to the axis of the drive shaft 960a of the motor 960. As shown in FIG. A gear 951 (pinion) mounted on the drive shaft 960 a engages with the rack portion 955 of the positioning pin 952 . That is, when the motor 960 is driven in forward and reverse directions, power is transmitted from the gear 951 to the rack portion 955 and the positioning pin 952 linearly reciprocates.

Guide members 953a and 953b are installed on the turntable 604 and guide the positioning pin 952 that reciprocates.

The connecting member 954 is a member that connects the rear end portion of the positioning pin 952 and the later-described swing mechanism 962 . The connecting member 954 is connected to the rear end portion of the positioning pin 952 with a pin 949 . That is, the connecting member 954 and the positioning pin 952 are connected via the pin 949 so as to be relatively rotatable.
Also, the connecting member 954 can reciprocate along a linear guide (not shown) provided in the scraping device 930 . This linear guide extends in the longitudinal direction of the positioning pin 952 . That is, the connecting member 954 can reciprocate along with the positioning pin 952 in the longitudinal direction of the positioning pin 952 .
Further, the connecting member 954 is prevented from rotating around the longitudinal axis by the linear guide (not shown). Therefore, the positioning pin 952 integral with the connecting member 954 is also non-rotatable. Therefore, the rack portion 955 of the positioning pin 952 is always engaged with the gear 951 .

The fixed-side engaging member 670 has a groove 672 that can be engaged with the positioning pin 952 . In addition, the fixed-side engaging member 670 is arranged on a fixed member 699 adjacent to the outer peripheral side of the turntable 604 .

The positioning mechanism 961 reciprocates the positioning pin 952 in conjunction with the elevation of the scraping arm 931 . When the positioning pin 952 protrudes from the turntable 604, the positioning pin 952 engages with the groove 672 of the fixed-side engaging member 670, and the turntable 604 is non-rotatably fixed. Also, when the positioning pin 952 retreats into the turntable 604, the engagement between the positioning pin 952 and the groove 672 is released, and the turntable 604 becomes rotatable.

The rocking mechanism 962 has a mounting member 945 and a rocking member 947 . The mounting member 945 and the swinging member 947 are integrally fixed with screws 948a and 948b. That is, the mounting member 945 and the swinging member 947 cannot move relative to each other.

The rocking member 947 is a substantially L-shaped plate-like member, as shown in FIG. The rocking member 947 is provided with two holes (not shown) through which the screws 948a and 948b are inserted. One end of the swinging member 947 is connected to the connecting member 954 by a pin 956 so as to be relatively rotatable. The other end of the swing member 947 is passed through the shaft member 614 . That is, the swinging member 947 can swing around the shaft member 614 . Both ends of the shaft member 614 are supported by support members 963 and 964 (FIGS. 21 and 23) fixed on the turntable 604. As shown in FIG.

The mounting member 945 has a main body 957 and mounting portions 958 and 959 as shown in FIG.
The body 957 is a plate arranged in a vertical position. The main body 957 is provided with holes 965a and 965b through which the screws 948a and 948b are inserted. Placement portions 958 and 959 are formed by vertically bending two portions of the upper side portion of the main body 957 . Both the mounting portion 958 and the mounting portion 959 are orthogonal to the main body 957, and are not in the same plane but are inclined to each other.
A projection 946 is provided on the mounting portion 958 . The projection 946 has the function of engaging with the coil spring 942 and fixing the coil spring 942 to the mounting portion 958 .
As shown in FIG. 24, the swinging member 947 and the mounting member 945 are integrally fixed with two screws 948a and 948b.

As shown in FIG. 26, the lower end of the coil spring 942 is fixed to the mounting portion 958 of the mounting member 945 . An upper end portion of the coil spring 942 is fixed to a spring fixing member 943 of the fixing portion 939 . A flange portion 944 a of the spring mounting portion 944 is in contact with the projecting plate 939 b of the fixed portion 939 . That is, the projecting plate 939b is sandwiched between the flange portion 944a and the nut portion 943b. The coil spring 942 is arranged between the flange portion 944 a on the fixed portion 939 side and the mounting portion 958 of the mounting member 945 of the swing mechanism 962 . Coil spring 942 is compressed.

As shown in FIG. 26 , the pressing surface 936 a of the raking arm 931 is placed on the placing portion 959 of the placing member 945 .

A proximal end of the scraping arm 931 is penetrated by a shaft member 614 . The shaft member 614 passes through the side plates 934a and 934b of the scraping arm 931, and inside the scraping arm 931, a driving pulley 623 is mounted as shown in FIG.
Since the shaft member 614 is supported by the support members 963 and 964 , the base end side of the scraping arm 931 is supported by the shaft member 614 .
The pressing surface 936 a of the raking arm 931 is placed on the placing portion 959 of the placing member 945 . The pressing surface 936a is formed on the distal end side of the portion of the raking arm 931 through which the shaft member 614 is inserted. Therefore, the mounting portion 959 presses the pressing surface 936 a formed on the bottom plate 934 c from below, or the pressing surface 936 a is placed on the mounting portion 959 , so that the scraping arm 931 is moved to the mounting member 945 . can be supported by
That is, the placing member 945 prevents the scraping arm 931 from rotating around the shaft member 614 due to its own weight.

Next, the operation of scraping device 930 will be described.

With the positioning pin 952 retracted into the turntable 604, the turntable 604 can be rotated. At this time, as shown in FIG. 27(a), the scraping arm 931 is raised. That is, the swing member 947 of the swing mechanism 962 shown in FIGS. 23 and 76 rotates counterclockwise about the shaft member 614 and stops, and the mounting portion 959 of the mounting member 945 rises. Therefore, the scraping arm 931 whose pressing surface 936a is pressed by the mounting portion 959 is in the raised posture shown in FIG. 27(a).

When the motor 960 is driven from this state, the positioning pin 952 is protruded from the turntable 604 and engaged with the groove 672 of the fixed-side engaging member 670, the turntable 604 is non-rotatably fixed. A connecting member 954 integrated with the positioning pin 952 pulls the swing member 947 of the swing mechanism 962 via the pin 956 . Therefore, the swing member 947 rotates clockwise about the shaft member 614 . The mounting member 945 integrated with the swinging member 947 also rotates clockwise together with the swinging member 947 . As a result, the position of the mounting portion 959 is lowered and the position of the mounting portion 958 is raised, so that the tip end side of the raking arm 931 is lowered, resulting in the state shown in FIG. 27(b).

27(a) to the state shown in FIG. 27(b), when the swinging member 947 rotates about the shaft member 614, the pin 956 fixed to the swinging member 947 moves to the lowest point ( directly below the shaft member 614 ) and rises slightly from the turntable 604 . That is, although the distance between the pin 956 and the shaft member 614 is always constant, the pin 956 is positioned higher in the state shown in FIG. 27(b) than in the state shown in FIG. 27(a).

As described above, the height position of the pin 956 changes with the rotation of the swing member 947, but since the connecting member 954 and the positioning pin 952 are connected by the pin 949, the connecting member 954 is centered on the pin 952. , and the connecting member 954 swings around the pin 949 while following the protruding movement of the positioning pin 952, and the end of the connecting member 954 to which the pin 956 is connected can be raised. .

When the raking arm 931 assumes the lowered posture shown in FIG. 27(b), the motor 950 shown in FIG. 23 is driven. The driving force of motor 950 is transmitted to scraping plate 609 via drive shaft 950 a , gears 628 , 641 , 633 , shaft member 614 , driving side pulley 623 , toothed belt 634 , driven side pulley 682 and shaft member 615 . be.

Further, when the drug scraping operation is completed, the motor 950 is stopped and the distal end side of the scraping arm 931 is raised. That is, the motor 960 is rotated in the opposite direction, the positioning pin 952 is retracted onto the turntable 604, and the mounting member 945 of the swing mechanism 962 is rotated counterclockwise around the shaft member 614. FIG. As a result, the mounting portion 959 of the mounting member 945 rises, and the tip side of the raking arm 931 rises.

The scraping plate 609 of the scraping mechanism 606 may collide with the distribution tray 201 when the scraping arm 931 changes from the raised posture to the lowered posture. However, the impact generated at that time is mitigated by the coil spring 942 of the fixed portion 939 .

Although not shown in FIG. 23, gear 641 is preferably provided with a one-way clutch. This one-way clutch prevents the scraping plate 609 from rotating in reverse due to its own weight.

(11) Cleaning Device The cleaning device 500 has a cleaning arm 501 whose tip side moves up and down by power, and a cleaning brush 502 is provided at the tip. Also, the cleaning brush 502 is rotatably mounted within the brush cover 503 . A suction device is connected to the brush cover 503 .

As shown in FIG. 33, when the cleaning brush 502 is viewed macroscopically, there is a hub member 505 provided with two grooves C and D, and the peripheral surface of the hub member 505 is flocked. .
As shown in FIG. 34, when the cleaning brush 502 is disassembled, it has a structure in which four disk-shaped brushes 506a, 506b, 506c, and 506d are connected by the same rotating shaft 508. As shown in FIG. That is, the cleaning brush 502 has two central disk-shaped brushes 506 a and 506 b and two side disk-shaped brushes 506 c and 506 d , the centers of which are connected by a rotating shaft 508 . However, the two central disc-shaped brushes 506a and 506b are in close contact with each other and form one central brush 507 apparently.

The side disk-shaped brushes 506c and 506d have thin disk portions. The disk portion is a disk having a shaft insertion hole in the center, and has an outer peripheral surface and side surfaces. Small holes are provided at equal intervals on the circumferential surface of the disk portion. Here the eyelets are inclined in the axial direction of the cleaning brush 502 . That is, the extension line of the small hole is directed toward the central axis of the cleaning brush 502, but does not pass through the center of the disk portion.

The disc-shaped brushes 506c and 506d on the side face are planted using these small holes. The hair is implanted by using stiff and self-supporting bristle materials, several tens of bristle materials are bundled to form a tuft, and one end of the tuft is inserted into the small hole and adhered.
Therefore, the free end side of the hair tuft protrudes from the peripheral surface of the disk portion. However, since the small holes in which the hair bundles are embedded are formed in an inclined direction as described above, the hair bundles as a whole are inclined toward the side surface.

The two central disk-shaped brushes 506a and 506b also have thin disk portions. The structure of the two central disc-shaped brushes 506a and 506b is similar to that of the side disc-shaped brushes 506c and 506d described above, and bristles are implanted using small holes formed in an inclined direction. As for the two central disk-shaped brushes 506a and 506b, the tufts of bristles as a whole are inclined toward the side surfaces.

The two central disk-shaped brushes 506a, 506b are closely joined together. If the two central disc-shaped brushes 506a and 506b that are matched are used as one central brush 507, it has a shape like a thick rotating brush. That is, the disc portion of the mating structure is a disc having a shaft insertion hole in the center. The disc portion of the mating structure is also provided with small holes at regular intervals on the circumferential surface of the disc portion.
However, in this embodiment, the small holes are provided in two rows.
Also, the small holes are inclined in the axial direction of the cleaning brush 502 . That is, the extension line of the small hole is directed toward the central axis of the cleaning brush 502, but does not pass through the center of the disk portion.
Here, if one side of the disk portion of the central brush 507 is the A side and the other side is the B side, the bristle bundles embedded in one row of holes have their ends inclined toward the A side, The bristle bundles embedded in the other row of holes have bristle tips that are inclined toward the B side surface.
That is, the center brush 507 has a mixture of tufts of bristles that are inclined in one direction and tufts of bristles that are inclined in the other direction.
Also, although small holes are provided at regular intervals in both one row of holes and the other row of holes, the distribution angles of the small holes are deviated. Therefore, the center brush 507 has a structure in which tufts of bristles inclined toward one side and tufts of bristles inclined toward the other side are alternately arranged.

The cleaning brush 502 has a central brush 507 in the center, side disk-shaped brushes 506c and 506d arranged on both sides of the central brush 507, and a rotating shaft 508 inserted through the three brushes to integrate them. Each disk-shaped brush is integrally fixed to the rotating shaft 508 and does not allow relative rotation.
A gear is provided at the end of the rotating shaft 508 .

Further, as shown in FIG. 38, there is a gap between the central brush 507 and the side disk-shaped brushes 506c and 506d on both sides, and the gap forms an annular groove. That is, there is an annular groove C between the disk-shaped brush 506c on one side and the central brush 507, and an annular groove D between the disk-shaped brush 506d on the other side and the central brush 507.

The two side disk-shaped brushes 506c and 506d arranged on both sides of the central brush 507 are attached in such a manner that their bristles are inclined toward the central brush 507 side.
As a result, the cleaning brush 502 has a hub member 505 and a row of flocked bristles is provided on the outer periphery of the hub member 505 .
The tufted rows are provided over four rows, and the tufted rows on both ends are groups of bristles that are inclined toward the center of the hub member 505 in a direction in which the tips of the bristles are slanted toward the center of the hub member 505 . The center-side flocked row of bristles includes a group of bristles that are slanted toward one end of the hub member 505 on the tip side and a group of bristles that are slanted toward the other end of the hub member 505 on the tip side. and another end direction inclined bristle group implanted in an inclined direction.

The brush cover 503 is a housing that can cover most of the cleaning brush 502 . In this embodiment, the brush cover 503 has a cochlea-shaped main body. That is, the side surface of the main body has an arcuate surface portion extending slightly less than 180 degrees, and both ends of the arcuate surface portion are extended. The two extensions extend in directions diverging from each other and form a cochlea-like shape as a whole. The ends of the two extensions are open.
A connecting portion is provided in a part of the body portion. The connecting portion is hollow and communicates with the space within the body portion.

More specifically, the brush cover 503 has two side walls 510 and a peripheral wall 509 connecting the ends of the two side walls except for the opening 513 .
Each of the two side walls 510 is formed by integrating an arcuate surface portion 511 extending slightly less than 180 degrees and extension wall portions 512 extending from both ends of the arcuate surface portion 511 . The extension wall portion 512 has straight left and right sides and an arc-shaped tip side. Therefore, one side of the side wall 510 is an arcuate side.
An opening 513 is formed between the arcuate sides of the two side walls 510 .

Here, in this embodiment, the two side walls 510 face each other in parallel, but the shapes of the two side walls 510 are different.
That is, as described above, the two side walls 510 are formed by integrating the arcuate surface portion 511 and the extension wall portion 512 . Here, the arcuate surface portions 511 of the two side walls 510 have the same shape and the same area, but the extension wall portions 512 have different sizes.
That is, the extension wall portion 512 is large on one side and small on the other side.
The extension wall portion 512a on the larger side has longer linear portions on the left and right sides than the other extension wall portion 512b.
The curvature of the arc-shaped side portion of the extended wall portion 512a on the larger side is equal to the curvature of the drug introduction groove 208 of the distribution plate 201 described above.
In addition, the total length of the arc-shaped side portion is longer than the medicine injection groove 208 of the distribution plate 201 . Therefore, when the arc-shaped portion is aligned with the medicine-inserting groove 208 of the distribution plate 201 , the two are matched without a gap, and both ends of the arc-shaped side extend slightly outside the medicine-inserting groove 208 .

The extension wall portion 512b on the smaller side has shorter linear portions on the left and right sides than the extension wall portion 512a on the other side. The curvature of the arc-shaped side of the small side extension wall 512b is equal to the curvature of the drug feeding groove 208 of the distribution plate 201, but the total length is equal to the curvature of the arc-shaped side of the large side extension wall 512a. short in comparison.
Therefore, when the opening 513 of the brush cover 503 is aligned with the drug charging groove 208 of the distribution plate 201, a gap is formed between the opening end of the small side wall 510 and the drug charging groove 208.

The cleaning brush 502 described above is rotatably arranged in the brush cover 503 . The cleaning brush 502 is mostly contained within the space inside the brush cover 503 and only partially exposed through the opening 513 .
A gear 504 provided on the cleaning brush 502 is exposed outside the brush cover 503 .
The brush cover 503 is attached to the tip of the cleaning arm 501 while enclosing the cleaning brush 502 .

The engaging lever 252 is made by bending a metal plate. The engagement lever 252 is a kind of lever, and has a fulcrum area 261 in the center as shown in FIG.
A fulcrum region 261 is a region in which a plate material is bent into an "L" shape, and a swing shaft 265 is provided at the corner portion.

One end of the fulcrum region 261 is bent to provide a container contact portion 262 . A working portion 263 is provided by bending the other end of the fulcrum region 261 . A hole 264 is provided in the acting portion 263 .

The holding member 253 is made by bending a wire symmetrically.
The holding member 253 has a rotating shaft portion 269 in the center, and both ends thereof are bent to form connecting portions 266a and 266b. Further, side holding portions 267a and 267b are provided by bending the distal end sides of the connecting portions 266a and 266b in a direction away from the rotating shaft portion 269. As shown in FIG. Front side holding portions 268a and 268b are provided by bending the distal end sides of the side holding portions 267a and 267b in a direction to approach each other.

The engagement lever 252 swings around the swing shaft 265 when the swing shaft 265 engages with a frame (not shown).
The holding member 253 is located near the engaging lever 252 , and the rotating shaft portion 269 is arranged parallel to the swing shaft 265 of the engaging lever 252 .
The holding member 253 swings about the rotary shaft portion 269 with the rotary shaft portion 269 held by the bearing 273 .

The engagement lever 252 and the holding member 253 are engaged via a spring 270 and a connection fitting 271 .
The connection fitting 271 is integrally attached to the rotating shaft portion 269 of the holding member 253 . A hole 275 is provided in the connection fitting 271 .
The spring 270 is a torsion coil spring having a coil portion 274 in the center and engaging portions at both ends.
A coil portion 274 of the spring 270 is attached to the holding member 253 with the rotary shaft portion 269 as the center. One engaging portion of the spring 270 is engaged with the hole 264 of the action portion 263 of the engaging lever 252 . The other engaging portion of the spring 270 is engaged with the hole 275 of the connecting fitting 271 attached to the holding member 253 .
Therefore, when the container abutting portion 262 of the engaging lever 252 is pushed down, the engaging lever 252 rotates clockwise with reference to FIG. 56, causing the spring 270 to rotate counterclockwise. Then, the holding member 253 engaged with the spring 270 rotates counterclockwise to raise the side holding portions 267a and 267b and the front side holding portions 268a and 268b.
Note that the container contacting portion 262 of the engaging lever 252 normally protrudes upward from the notch portion 260 of the pedestal portion 256 of the mounting table 251 .

When the drug container 2 is attached to the drug container temporary placement unit 250 , the drug container 2 is placed on the mounting table 251 using a human hand or the hand part 707 of the robot 702 .
As described above, the container contacting portion 262 of the engaging lever 252 protrudes upward from the notch portion 260 of the mounting table 251. Therefore, when the drug container 2 is placed on the mounting table 251, the container contacting portion 262 is shaken. The side holding portions 267a and 267b and the front side holding portions 268a and 268b rise instead. The side holding portions 267a and 267b hold the side surfaces of the medicine container 2, and the front side holding portions 268a and 268b hold the conveying iron plate portion 157 side of the medicine container 2. As shown in FIG. The fixing iron plate portion 6 side of the drug container 2 is held by the backrest portion 255 of the mounting table 251 .
Therefore, the drug container 2 is held on five sides by the pedestal portion 256 and the backrest portion 255 of the mounting table 251 and the side holding portions 267a and 267b and the front side holding portions 268a and 268b of the holding member 253, and does not fall off.

(21) Cleaning the drug container (scraping member)
In the embodiment shown in FIG. 51, the door portion 9 is closed, and the scraping member 280 (cleaning portion) is provided directly above the drug container temporary placement portion 250 . The scraping member 280 is provided not on the door portion 9 but on the main body side of the medicine dispensing device 1 .
The scraping member 280 has a concave portion 281 (container contact portion) whose cross-sectional shape conforms to the shape of the container body 5 . A suction port 282 is opened inside the concave portion 281 (container contact portion), and the suction port 282 is connected to a suction device (not shown).

52 is an exploded perspective view of the scraping member 280, and FIG. 53 is a cross-sectional perspective view of the scraping member 280. FIG.
The scraping member 280 is composed of a body portion 283 and a wiping member 234 as shown in FIG.
The body portion 283 is made of hard resin, and is provided with the concave portion 281a as described above.

The wiping member 234 is made of soft resin such as silicon rubber or rubber, and is provided with a concave portion 281b like the body portion 283. As shown in FIG.
The wiping member 234 is attached to the lower portion of the body portion 283 with a slight gap therebetween. 53, the tip of the recessed portion 281b of the wiping member 234 is at a position protruding slightly forward from the tip of the recessed portion 281a of the main body portion 283. As shown in FIG.
Further, as described above, there is a small gap between the wiping member 234 and the body portion 283 , and the gap serves as the suction port 282 .

The scraping member 280 is a member provided for cleaning the side surface of the drug container 2 . In the above-described embodiment, the drug is directly supplied from the drug container 2 to the distribution tray 201 . Therefore, after the medicine is supplied, the medicine may adhere to the side surface of the medicine container 2 due to static electricity or the like. In particular, the medicine may stick to the vicinity of the medicine discharge portion 8 of the medicine container 2 .
Then, the side surface of the drug container 2 is pressed against the concave portion 281 (container contact portion) of the scraping member 280, and the drug container 2 is slid downward or upward.
At the same time, a suction device (not shown) is activated.
Here, in this embodiment, there is a hard and highly rigid main body portion 283, and a slightly soft wiping member 234 is therebelow. Also, the wiping member 234 protrudes from the body portion 283 . Therefore, when the medicine container 2 is slid downward or upward, the wiping member 234 wipes the side surface of the medicine container 2 and the vicinity of the medicine discharge part 8 to remove the stuck medicine. In this way, the medicine adhering to the side surface of the medicine container 2 is wiped off and sucked from the suction port 282 by the suction device. Therefore, even if the drug residue remains on the side surface of the drug container 2 , it is cleaned by the scraping member 280 .

As described above, the drug container 2 is attached to the drug container temporary placement unit 250 using a human hand or the hand unit 707 of the robot 702. When attaching to the portion 250 , it is preferable to wipe the side surface of the drug container 2 with the scraping member 280 before attaching to the temporary placement portion 250 . That is, the drug container 2 gripped by the hand portion 707 is pressed against the container contact portion 281 to scrape off the drug adhering to the side surface of the drug container 2 .
Also, when the robot 702 returns the used drug container 2 to the container installation portion 103 of the drum member 102 , it is desirable to wipe the side surface of the drug container 2 with the scraping member 280 before attaching it to the drug container temporary placement portion 250 .

(22) Hopper Cleaning In the hopper cleaning operation described above, it is recommended to charge the cleaning agent into the powdered medicine charging hopper 413 . The cleaning agent is a release agent, powder other than the prescribed drug, and powder for cleaning the inside of the hopper. Also, the cleaning agent is selected to be harmless even if it enters the human mouth, regardless of whether it has a medicinal effect or not.
The cleaning agents are powders or particles that are harmless to the human body, such as baking soda powder, lactose and starch.
FIG. 60 is a conceptual diagram of an embodiment having a function of charging a cleaning agent into powdered drug charging hopper 413 during a cleaning operation.
In the embodiment shown in FIG. 60 , a cleaning agent charging device 423 is provided near the introduction side opening of the powdered drug charging hopper 413 . An opening/closing plate 416 is provided at the discharge side opening (drug discharge port) at the end of the powdered medicine charging hopper 413 , and an air nozzle 422 is provided near the outside of the opening/closing plate 416 .

The powder medicine charging hopper 413 has a shape as shown in FIG. 65, for example, and has a discharge side opening (medicine discharge port) 1000 at the bottom and an introduction side opening 1001 at the top. An opening/closing plate 416 is provided at the discharge side opening 1000 .
A suction opening 1002 is opened on the side surface of the powdered medicine charging 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 is. 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 powdered medicine charging hopper 413 . That is, the suction opening 1002 is provided at the center of the side surface of the powdered medicine charging 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 hose is connected to the suction opening 1002 , and the end of the pipe member 1010 is connected to a suction device 415 . That is, the pipe member 1010 constitutes part of a suction path from the suction opening 1002 to the suction device 415 .

Further, in this embodiment, the pipe member 1010 has a curved portion 1012 . That is, in the present embodiment, the suction path is curved greatly in the vicinity of the suction opening 1002 . That is, when the tubular member 1010 is viewed from above, a curved portion 1012 can be seen.
Also, the suction opening 1002 is flat. Therefore, the flow velocity of air in the vicinity of the suction opening 1002 differs between the side near the outside of the curve and the side near the inside.

The hopper cleaning operation performed by charging the cleaning agent is performed in the following procedure.
As a first step, a cleaning agent is charged into the powder drug charging hopper 413 . At this time, the opening/closing plate 416 at the end of the powdered medicine charging hopper 413 is closed.
Then, the charging opening of the powder drug charging hopper 413 is closed by the hopper closing member 400 . In this state, the suction member is operated. As a result, a violent air flow is generated inside the powdered drug introduction hopper 413 , and the cleaning agent violently swirls and collides with the inner wall of the powdered drug introduction hopper 413 .
Since the opening/closing plate 416 at the end of the powdered medicine charging hopper 413 is closed here, the amount of air supplied into the powdered medicine charging hopper 413 is limited. Therefore, although the cleaning agent swirls within the powdered medicine charging hopper 413, the amount of air sucked by the suction member is small. Therefore, the cleaning agent is simply agitated in the powdered medicine charging hopper 413, and the amount sucked out by the suction member is small.
Therefore, the cleaning agent stays in the powdered medicine charging hopper 413 and collides with the inner wall of the powdered medicine charging hopper 413 for a long time. Also, like a cyclone vacuum cleaner, the centrifugal force of the cleaning agent acts and hits the inner surface of the powdered medicine charging hopper 413, so the impact of the collision is large. Therefore, the medicine adhering to the inner wall of the powder medicine charging hopper 413 is peeled off.

After that, the opening/closing plate 416 at the end of the powdered medicine charging hopper 413 is opened. More preferably, the opening and closing of the opening and closing plate 416 are repeated.
As a result, outside air is introduced from the end of the powdered medicine feeding hopper 413 into the powdered medicine feeding hopper 413, which tends to have a negative pressure, and an even more intense air flow is generated in the powdered medicine feeding hopper 413, causing the cleaning agent to swirl violently to feed the powdered medicine. The medicine that collides with the inner wall of the hopper 413 and adheres to the inner wall of the powdered medicine charging hopper 413 is peeled off.

Especially in the present embodiment, the suction opening 1002 is flat and is a suction path, and the position in the immediate vicinity of the suction opening 1002 is greatly curved. It is different on the side closer to the inside and the side closer to the inside.
In this embodiment, the flow velocity of air increases near the inner wall 1003 and decreases near the opposing inner wall 1006 .
Therefore, a strong swirling flow is generated in the powdered medicine charging hopper 413 . Also, air is introduced from a discharge side opening 1000 provided in the lower portion of the powdered medicine charging hopper 413 . Therefore, the airflow is swirled along the inner wall of the powdered medicine charging hopper 413 and advances from the lower side to the upper side. Therefore, the introduced cleaning agent acts as if scraping the inner wall of the powdered drug charging hopper 41 to scrape off the agent, which is rolled up together with the cleaning agent and discharged by the suction member.
In this embodiment, since the suction opening 1002 is provided near the upper end of the powdered medicine charging hopper 413, substantially the entire inner wall of the powdered medicine charging hopper 41 is cleaned.

The peeled medicine is sucked out by the suction member together with the cleaning agent, and discharged out of the powdered medicine introduction hopper 413 .
When the opening and closing of the opening/closing plate 416 are repeated, the cleaning agent is stirred while the cleaning agent is stopped in the powder injection hopper 413, and the cleaning agent is stirred while air is introduced and part of the cleaning agent is discharged. will be

Also, the chemical adhering 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 .
That is, according to the experience of the present inventors, the drug may adhere to the opening/closing plate 416 provided at the discharge side opening 1000 of the powdered drug charging hopper 413 . Here, the inner side of the opening/closing plate 416 (the inner surface side of the powdered medicine feeding hopper 413) can be cleaned by utilizing the impact caused by stirring the cleaning agent, but the outer surface of the opening/closing plate 416 itself collides with the cleaning agent. I can't let you.
Therefore, in the present embodiment, air is blown directly toward the outside of the opening/closing plate 416 from an air nozzle 422 provided near the opening/closing plate 416 to remove the medicine adhering to the outside of the opening/closing plate 416 .

Since the opening/closing plate 416 is normally provided at a recessed position in the device, it is difficult to apply the air jet when the opening/closing plate 416 closes the discharge side opening 1000 . Therefore, in this embodiment, the air nozzle 422 is provided at a position where the air jetted when the opening/closing plate 416 is in the open posture hits.
Moreover, since there is a packaging paper in the vicinity of the opening/closing plate 416, the medicine peeled off by the air is collected in the packaging paper.
A series of operations will be described collectively. A cleaning agent is put into the powdered drug introduction hopper 413 and suction is started. Blow air directly to the outside. Stop suction and air after 5 to 10 seconds.

In the embodiment shown in FIG. 60, the cleaning agent charging device 423 is provided near the introduction side opening of the powdered medicine charging hopper 413, but the cleaning agent may be charged into the powdered drug charging hopper 413 using the drug container 2. . That is, in the previous embodiment, the cleaning agent injection device 423 was provided as the cleaning agent injection means for injecting the cleaning agent, but the chemical container 2 may be utilized as the cleaning agent injection means.
For example, a specific medicine container 2 is filled with a cleaning agent such as baking soda and stored in the container storage device 101 like other medicine containers 2 .
Then, the cleaning agent in the drug container 2 is charged into the powdered drug charging hopper 413 by an operation similar to the operation of taking out the powdered drug from the drug container 2 and charging it into the powdered drug charging hopper 413 .

Specifically, when a drug that requires cleaning work is packaged, or when it is found that the powdered drug input hopper 413 is dirty by a residual drug sensor or the like, the cleaning agent is automatically or manually filled. A drug container 2 is selected.
Then, the hand portion 707 of the robot 702 holds the drug container 2 , moves the drug container 2 , and places the drug container 2 filled with the cleaning agent on the container placing device 3 .
After that, the anti-vibration table 23 of the container placing device 3 is operated to put the powdered medicine from the drug container 2 into the distribution tray 201 of the powdered medicine distribution device 202 . Then, the cleaning agent is discharged from the distribution tray 201 by the scraping device 930 and charged into the powdered drug charging hopper 413 .
It should be noted that this series of operations is executed at a speed faster than the operation speed during normal drug packaging.

In addition, in the case of ordinary medicine packaging, the opening/closing plate 416 is closed when the medicine is put from the medicine container 2 into the powder medicine introduction hopper 413, but when the cleaning agent is put into the powder medicine introduction hopper 413, the opening/closing plate 416 is closed. Keep 416 closed.

(23) Remaining Medicine Detection Sensor Next, the remaining medicine detection sensor 372 for the distribution tray 201 will be additionally described. A remaining medicine detection sensor 372 (hereinafter simply referred to as a remaining medicine detection sensor 372) for the distribution tray 201 is an optical sensor in which a light projecting section and a light receiving section are integrated.
The light projecting portion of the remaining medicine detection sensor 372 emits a beam having a width corresponding to the width of the medicine introduction groove 208 of the distribution plate 201, as shown in FIG. The light projecting portion of the remaining medicine detection sensor 372 is fixed, and the area irradiated with the beam is limited to a certain area.
If there is no dirt or residual medicine at the irradiation position of the beam, the light emitted from the light projecting section is specularly reflected on the surface of the medicine charging groove 208 and does not return to the light receiving section.
On the other hand, if there is dirt or residual medicine at the irradiation position of the beam, the light emitted from the light projecting part hits the residual medicine and is diffusely reflected, and part of it enters the light receiving part of the residual medicine detection sensor 372 .
Therefore, it is possible to detect whether or not there is dirt or residual medicine in the irradiation section.

The remaining medicine detection work is performed by irradiating light from the light projecting part of the remaining medicine detection sensor 372 (hereinafter simply referred to as the remaining medicine detection sensor 372) while rotating the distribution tray 201. FIG.
Specifically, after cleaning the surface of the distribution plate 201 by the cleaning device 500, the operation of detecting the remaining medicine is performed.
As described above, the distribution tray 201 is cleaned by rotating the cleaning brush 502 and rotating the distribution tray 201 one or more turns. After that, the rotation of the cleaning brush 502 is stopped, and the distribution plate 201 is rotated by one or more rotations. At that time, light is emitted from the light projecting portion of the remaining medicine detection sensor 372 to inspect whether there is dirt or remaining medicine.
When the light receiving unit detects the light and it is found that there is residual medicine or the like in the distribution tray 201, the cleaning brush 502 is rotated again to clean the distribution tray 201 again. If there is no remaining medicine or the like on the distribution tray 201 , the cleaning arm 501 is rotated to raise the cleaning brush 502 provided at the tip, and the cleaning brush 502 is pulled out of the medicine feeding groove 208 of the distribution tray 201 .

If the remaining medicine detection sensor 372 detects dirt or remaining medicine even though the surface of the distribution tray 201 has been cleaned, a configuration may be adopted in which the user is notified by sound or image. Triggered by the notification, the user can visually confirm the state of the distribution tray 201 and confirm whether the cause of the notification is dirt, foreign matter, or drug residue.

If there is a residue of the medicine, the cleaning brush 502 cleans again, and then the remaining medicine detection sensor 372 detects the remaining medicine. Even if this operation is performed a plurality of times (for example, three times), if residue is found on the distribution tray 201, an alarm by sound or image is issued. The alarm has a cancel mode and a skip mode. The cancellation mode is a mode in which the issued alarm is stopped and the cleaning by the cleaning brush 502 is performed again. The skip mode is a mode in which an alarm is issued, but cleaning by the cleaning brush 502 is not performed, and the user checks the presence or absence of remaining medicine and manually cleans as necessary.

(24) Cleaning of scraping portion In the scraping portion cleaning operation described above, it is desirable to change the relative positions of the cleaning brush 502 and the scraping mechanism 606 during the operation.
A cleaning brush 521, which is a modification of the cleaning brush 502, will be described below.
A cleaning brush 521 employed in this embodiment is used in place of the cleaning brush 502 in the cleaning device 500 shown in FIGS. The cleaning brush 521 has a hub member 522 provided with two grooves 525 and 526 (FIG. 72) like the cleaning brush 502 described above, and the peripheral surface of the hub member 522 is flocked. .
The cleaning brush 521 of this embodiment has a structure in which three disk-shaped brushes 526a, 526b, and 526c are connected.

The disc-shaped brushes 526a and 526c on the side face are flocked. Hair bundles 523a and 523b (central direction inclined bristle groups) implanted in disk-shaped brushes 526a and 526c are both inclined toward the center. As shown in FIG. 71, hair tufts 523 (flocked rows) implanted in the disk-shaped brushes 526a and 526c include long bristle tufts 523a and short bristle tufts 523b.

Hairs are planted in two rows on the disk-shaped brush 526b in the center. The hair bundles 524 implanted in each row include hair bundles 524a (one end direction inclined hair group) with long hairs inclined toward the side and hair bundles 524b (other end direction inclined hair group) with short hairs inclined toward the side. direction-inclined hair group), and hair bundles 524c having long and straight hairs.

As shown in FIG. 22 , the scraping mechanism 606 is a member having a scraping plate 609 , a scraping plate 607 and a partition plate 603 . The scraping plate 609, the scraping plate 607, and the partition plate 603 are constructed integrally. A peripheral seal member 683 made of rubber or resin is provided around the raking plate 609 so as to be in close contact with the drug introduction groove 208 of the distribution plate 201 . A rubber or resin scraping sealing material 685 is also provided on the edge of the scraping plate 607 so as to be in close contact with the medicine feeding groove 208 .

The scraping portion cleaning operation is performed by pressing the cleaning brush 521 against the side surfaces of the scraping plate 609 , the scraping plate 607 and the partition plate 603 , the peripheral sealing material 683 and the scraping sealing material 685 . Therefore, in principle, the scraping plate 609 of the scraping mechanism 606 and the partition plate 603 are deeply inserted into the grooves 525 and 526 of the cleaning brush 521 as shown in FIGS.
However, when the scraping plate 607 rotates and the cleaning brush 521 cleans the scraping plate 607 and the partition plate 603, the cleaning brush 521 may contact the scraping plate 607 and the scraping sealing material 685 too strongly. There is a concern that the scraping sealing material 685 and the like may be damaged. Therefore, when the scraping plate 607 rotates and the cleaning brush 521 cleans the scraping plate 607 and the partition plate 603, the cleaning arm 501 is swung to perform cleaning as shown in FIG. 72(c). It is desirable to move brush 521 (hub member 522 ) away from scraping mechanism 606 .

As an ideal operation, the scraping plate 609 of the scraping mechanism 606 and the partition plate 603 are first deeply inserted into the grooves 525 and 526 of the cleaning brush 521, and the cleaning brush 521 is rotated while the scraping plate 609 is moved. When it rotates and the scraping plate 607 approaches the cleaning brush 521 (hub member 522), the cleaning brush 521 is released a little. After the cleaning brush 521 has passed the scraping plate 607 , the cleaning brush 521 is brought closer to the scraping mechanism 606 side again and the cleaning brush 521 is deeply inserted into the scraping mechanism 606 .
After the scraping plate 609 rotates once or several times, the cleaning brush 521 is slightly released. In this state, while the cleaning brush 521 is rotating, the scraping plate 609 is rotated to intensively clean the peripheral sealing material 683 and the scraping sealing material 685 .

(25) Surveillance Camera Next, the surveillance camera 540 that monitors the discharge of the powdered medicine from the medicine container 2 will be described. The monitoring cameras 540 are installed one by one next to the remaining medicine detection sensor 372 described above. The surveillance camera 540 has a rotating device (not shown), and can change the shooting location.
The monitoring camera 540 is set so as to photograph the vicinity of each container placing device 3 in particular. More specifically, in a state where the drug container 2 is installed on each container placing device 3, the vicinity of the drug discharge portion 8 of the drug container 2 and the distribution tray 201 are photographed.
The video captured by the monitoring camera 540 can be viewed in real time on a personal computer or the like provided outside. Also, the video captured by the monitoring camera 540 is recorded in a recording medium (not shown) and can be checked later.
The medicine dispensing device 1 of this embodiment is entirely covered with the housing 7 as described above, and the medicine is distributed in a sealed space. is provided. Therefore, the user can check the falling state of the powdered medicine and the distribution state to the distribution tray 201 by looking at the personal computer or the like provided outside.
In addition, the user can adjust the vibration strength of the anti-vibration table 23 and the rotational speed of the distribution plate 201 by observing how the powdered medicine falls.
As described above, the image captured by the surveillance camera 540 is recorded in a recording medium (not shown), so that if there is a problem, it can be used to find the cause of the problem.

(26) Information Recording Member As described above, an RFID chip is attached to the drug container 2 as the information recording member 15 .
In the information recording member 15, the remaining amount of the medicine in the medicine container 2 is recorded in addition to the name of the medicine.
In this embodiment, when the drug dispensing device 1 is started, the container storage device 101 reads from the information recording member 15 the types and remaining amounts of drugs contained in all the drug containers 2 mounted on the drum member 102. issued and recorded in the controller. That is, the information on the information recording member 15 is read by the information reading device 335 by rotating the drum member 102 . In addition, which position of the drum member 102 contains which drug container 2 is confirmed and recorded.

Further, in this embodiment, an information reading/writing device 27 is provided near the container placing device 3 . Then, when the drug container 2 is taken out from the container storage device 101 and placed on the container placing device 3 to package the drug, it is confirmed whether it is the target drug.

Further, when the dispensing work is completed, the remaining amount of medicine in the medicine container 2 recorded in the information recording member 15 is rewritten by the information reading/writing device 27 in the vicinity of the container placing device 3 .

Before the drug container 2 is returned to the container storage device 101 after the packaging is completed, the drug container 2 is placed in the drug container temporary placement section 11 and the weight of the drug container 2 is measured again. In this manner, the drug dispensing device 1 of this embodiment double-checks the weight of the drug.

After the drug container 2 is returned from the drug container temporary placement unit 11 to the container storage device 101, the returned drug container 2 is brought closer to the information reading device 335 by rotating the drum member 102, and the drug returned to the container storage device 101 is It is verified that the container 2 is the original drug container 2 .

When the drug container 2 is stored in the drug delivery device 1 from the outside, information on the drug stored in the drug container 2 is input to an input device (not shown). Then, the drug container 2 is placed in the drug container temporary placement section 11 , and the weight of the drug container 2 is measured by operating a predetermined switch, and the weight is written in the information recording member 15 . Further, information on the drug is read out from the information recording member 15, and it is confirmed that the drug is the drug input by the user to the input device.

The same is true when the medicine in the medicine container 2 is insufficient and the medicine container 2 is replenished with medicine and the medicine container 2 is accommodated in the medicine dispensing device 1 .
When the medicine in the medicine container 2 is insufficient, the medicine container 2 is moved from the container placing device 3 or the container storage device 101 to the medicine container temporary placement portion 11 of the door portion 9 .
