Description

The present invention relates to a drug feeder that weighs and takes out a drug in a predetermined amount. The drug feeder of the present invention is suitably used as a device for supplying powder to a powder distribution device that distributes powder. Further, the drug feeder of the present invention is suitable as a device built in a powder dispensing device having a function of distributing powder by the powder distributing device and further packaging the powder individually.
The present invention also relates to a drug dispensing device having a built-in drug feeder.

In recent years, large hospitals and large-scale pharmacies have introduced powder packaging devices and drug dispensing devices having a powder packaging function. Here, the powder packaging device is a device for individually packaging powders and the like for each dose. If a powder packaging device is used, most of the work of packaging powders and the like in doses can be automated.
The powder packaging device 200 disclosed in Patent Document 1 is a device for individually packaging powders for each dose, and as shown in FIG. 49, the drug supply device 201, the powder distribution device 202, and the drug packaging are inside. It has a device 203.
The drug supply device 201 disclosed in Patent Document 1 is composed of a charging hopper 205 and a powder feeder 206 as shown in FIGS. 49 and 50.
As shown in FIG. 50, the powder feeder 206 is provided with two piezoelectric elements 207 and 208 under the trough 210 to vibrate the trough 210.

As shown in FIG. 49, the powder distribution device 202 is composed of a distribution plate 212 and a scraping device 215. The distribution dish 212 has an arcuate cross section and has an annular groove 216 in plan view. The distribution plate 212 is rotated at a constant speed by the motor 219.
The scraping device 215 has a disk 217 that moves up and down and rotates, and the disk 217 is provided with a scraping plate 218.

The drug packaging device 203 is composed of a packaging hopper 220 and a packaging device 221 as shown in FIG. 49.

Next, a procedure for packaging the powder using the powder packaging device 200 will be described.
The work of packaging the powder is performed by the pharmacist operating the powder packaging device 200 according to the doctor's prescription. That is, the pharmacist confirms the doctor's prescription and takes out the medicine bottle containing the prescribed powder from the medicine rack (not shown). Then, a scale such as a balance is used to weigh the total weight of the prescribed specific powder.
That is, it is a powdered drug to be taken 3 times a day, and when 1.0 gram is prescribed and the drug for 20 days is prescribed, (1.0 × 3 × 20 = 60) gram. Powder is taken out. More specifically, the container is placed on the scale and tare is performed, the powder is removed from the medicine bottle using a spatula, the powder is placed in the container on the scale, and 60 grams of powder is weighed out.

Then, 60 grams of the weighed powder is charged into the charging hopper 205 of the drug supply device 201.
At the same time, the piezoelectric elements 207 and 208 (FIG. 50) of the powder feeder 206 are energized to vibrate the trough 210, and the distribution pan 212 is further rotated at about 20 to 30 rotations per minute.
The powder charged into the charging hopper 205 falls from the opening at the lower end of the charging hopper 205 to the trough 210 of the powder feeder 206. Then, as the trough 210 vibrates, the powder slowly moves to the tip side and is rectified. Further, while moving on the trough 210, rectification progresses, and the flow of the drug becomes a laminar flow state. That is, the distribution of the drug in the cross section in the direction orthogonal to the flow is constant, and the distance that the drug travels per unit time is also constant. As a result, 60 grams of powder is evenly dispersed and slowly moves towards the tip at a constant rate per hour.
Finally, the powder that moves at the head reaches the tip of the trough 210, and the powder that moves at the head falls from the tip of the trough 210 into the groove 216 of the distribution dish 212. Further, the powdered medicine that follows will fall into the distribution dish 212 by a certain amount per hour. Finally, the last powder drops into the distribution dish 212, and all 60 grams of powder enters the groove 216.

On the other hand, since the distribution plate 212 is rotating at a predetermined speed, the powder falling from the trough 210 is evenly distributed in the groove 216 of the distribution plate 212.
That is, the powder feeder 206 gradually drops the powder into the distribution plate 212, and the distribution plate 212 rotates at a constant speed, so that the powder is evenly distributed in the groove 216 of the distribution plate 212.

When the dropping of the powder onto the distribution plate 212 is completed, the rotation of the distribution plate 212 is temporarily stopped. After that, the disc 217 of the scraping device 215 is dropped into the groove 216 of the distribution plate 212. After that, the distribution plate 212 is rotated by an angle corresponding to the number of distributions. In the previous example, since 60 grams of powder is divided into 60 packets, the distribution dish 212 is rotated by (60/360) degrees, and the powder is applied to the front side of the disk 217 by (60/360) degrees. Gather. Then, the disk 217 is rotated, and the powder for (60/360) degrees is scraped out of the distribution plate 212 by the scraping plate 218 and put into the packaging hopper 220. The powder that has fallen from the packaging hopper 220 is packaged in the packaging device 221.

Japanese Unexamined Patent Publication No. 2000-85703

By using the powder packaging device 200 disclosed in Patent Document 1, most of the work of packaging the powder in doses can be automated.
However, it cannot be said that the powdered powder packaging device 200 of the prior art is a device that can completely automate the packaging of powdered medicine because there is still a process that requires manual labor.
That is, in the powder packaging device 200 of the prior art, it is indispensable for the pharmacist to take out a medicine bottle containing a desired powder from the medicine rack and weigh a predetermined amount of powder from the medicine bottle.

Therefore, it is an object of the present invention to pay attention to the above-mentioned problems of the prior art and to develop a drug feeder capable of more highly automated the work of weighing powder.

An embodiment for solving the above-mentioned problems is a drug feeder composed of a drug container and a main body device, the drug container is removable from the main body device, and the drug container has the drug container. There is a drug discharge section that discharges the drug to the outside, and the drug discharge section can be opened and closed. It has a container holding means for fixing and a weight measuring means for directly or indirectly measuring the weight of the drug container, the drug container is placed on a shaking table, and the drug container is fixed to the shaking table by the container holding means. The drug feeder is characterized in that it is possible to vibrate the shaking table to discharge the drug little by little from the drug discharging unit and detect the discharged amount of the drug by a weight measuring means.
It is desirable that the drug container has a movable lid portion, and the movable lid portion can maintain the drug discharging portion in a closed state and an open state.

In the drug feeder of this embodiment, the drug container is fixed to the shaking table, and the drug container is brought into direct contact with the shaking table. By vibrating the shaking table in this state, the whole or part of the drug container can be vibrated. Therefore, the drug in the drug container slowly moves to the drug discharge section side, the drug is rectified, the flow is laminarized, and the drug is discharged from the drug discharge section.
Further, since the drug feeder of the present invention is equipped with a weight measuring means, it is possible to detect the amount of the drug discharged and to automate the work of weighing out the powder or the like.

It is desirable that the drug feeder is provided with a plurality of contact sensors for detecting whether or not the drug container is in contact with the shaking table.

Since the drug feeder of this embodiment is provided with a plurality of contact sensors for detecting whether or not the drug container is in contact with the shaking table, the posture of the drug container with respect to the shaking table can be confirmed. Therefore, the drug feeder of the present invention can keep the variation in the posture of the drug container with respect to the shaking table within a certain range.
That is, in the drug feeder of this embodiment, the drug container is brought into direct contact with the shaking table, and the shaking table is vibrated to vibrate the drug container to move the drug. Therefore, the posture of the drug container has a certain tolerance. Must be within range.
For example, in order to discharge a certain amount of drug per unit time from the drug container by vibration, it is desirable that the drug container is in a horizontal posture. Assuming that the drug container is attached to the shaking table with the drug discharge portion side of the drug container tilted upward, it is difficult for the drug to move to the drug discharge portion side even if vibration is applied.
If the axis of the drug container and the center line of the shaking table are out of alignment or intersect with each other, the drug will not be in a laminar flow state when the drug is moved by vibration, resulting in turbulent flow. It will be in a state. That is, the direction in which the shaking table tries to move the drug and the direction of the flow path of the powder or the like regulated by the peripheral wall of the drug container are different, and the distribution of the drug in the cross section intersecting the flow direction varies.
On the other hand, in this embodiment, since the variation in the posture of the drug container with respect to the shaking table can be kept within a certain range, the distribution of the drug in the cross section intersecting the flow direction becomes uniform. Therefore, according to the present invention, the movement of the drug is likely to be rectified, and a laminar flow state is likely to occur. Therefore, according to the drug feeder of this embodiment, the variation in the amount of emissions per unit time is small.

In the drug feeder, it is desirable that the drug container is partially or wholly made of a magnetic material, and the container holding means has a magnet.
The magnet is preferably an electromagnet.

In this embodiment, an electromagnet is used as the container holding means. Therefore, the drug container can be adsorbed and held on the shaking table simply by energizing the electromagnet. Further, when the energization of the electromagnet is stopped, the medicine container can be separated from the shaking table.

The magnet is provided on the shaking table, and there is an elastic member between the shaking table and the magnet. When the drug container is attracted to the magnet, the magnet moves relative to the shaking table due to the attractive force of the magnet. It is desirable that the magnet and the drug container and the shaking table and the drug container come into contact with each other.
The magnet is preferably an electromagnet.

In the drug feeder of the present invention, when the drug container is attracted to the electromagnet or the like, the electromagnet or the like moves relative to the shaking table due to the attractive force of the electromagnet or the like, and the electromagnet or the like and the drug container or the shaking table and the drug container come into contact with each other. be able to. Therefore, in the drug feeder of the present invention, the adhesion between the shaking table and the drug container is high, and the vibration of the shaking table can be accurately transmitted to the drug container.

The drug container is partially or wholly a magnetic material, and the container holding means has a permanent magnet and an electromagnet. At least, the drug container is fixed to the shaking table by the magnetic force of the permanent magnet, and the electromagnet is energized to energize the permanent magnet. It is recommended that the drug feeder be configured to release the fixation of the drug container to the shaking table by generating a magnetic force that cancels out.

In the drug feeder of this embodiment, the container holding means has a permanent magnet and an electromagnet, and the drug container is fixed to the shaking table by at least the magnetic force of the permanent magnet. Therefore, when the drug container is attached to the main body device, the amount of electricity applied to the electromagnet is small. If a configuration is adopted in which the drug container is fixed to the shaking table only by the magnetic force of the permanent magnet, it is not necessary to energize the electromagnet while the drug container is fixed to the shaking table. Therefore, the electromagnet does not generate heat and the drug in the drug container is not heated. Further, since it is not necessary to energize the electromagnet while the drug container is fixed to the shaking table, the power consumption is small. Therefore, the power consumption of the entire drug feeder is small and the heat generation is small, so that the drug is not easily affected.

It is desirable that the drug feeder be provided with a cooling means for cooling the main body device.

The chemical feeder has a vibration isolator, has a vibration isolator between the vibration isolator and the vibration isolator, and the weight measuring means detects the total weight of the vibration isolator, and the weight measuring means. It is desirable that the amount of drug discharged is detected by the change in the detected weight.

In the drug feeder of this embodiment, the weight measuring means detects the total weight of the vibration isolator. Further, the vibrating table is vibrated by the vibration isolating means, but since there is a vibration isolating member between the vibrating means and the vibration isolating table, the vibration of the vibrating means is not easily transmitted to the vibration isolating table.
In the drug feeder of this embodiment, as described above, the total weight of the vibration isolator is detected by the weight measuring means, so that the weight measuring means is not easily affected by vibration and the weight of the drug container or the like can be accurately measured. ..

An intermediate table and a vibration-proof table that supports the intermediate table via a vibration-proof member are provided. It is desirable that the drug feeder detects the total weight of the vibration isolator and detects the amount of the drug discharged by the change in the detection weight of the weight measuring means.

Also in the drug feeder of this embodiment, the weight measuring means detects the total weight of the vibration isolator. That is, the weight measuring means measures all the weights of the shaking table, the drug container on the shaking table, the intermediate table, the vibration isolator, the vibrating means, and the container holding means.
Further, the vibrating table is vibrated by the vibrating means, but all the vibrating members are placed on the intermediate table, and the vibration isolator supports the intermediate table via the vibration isolating member. Vibration of the intermediate table etc. is not easily transmitted to the vibration isolation table.
In the drug feeder of this embodiment, as described above, the total weight of the vibration isolator is detected by the weight measuring means, so that the weight measuring means is not easily affected by vibration and the weight of the drug container or the like can be accurately measured. ..

The drug container has a drug storage section for storing the drug, has a stenosis opening and a lead-out path section between the drug storage section and the drug discharge section, and the drug container is placed on a shaking table. A drug feeder that vibrates the drug container, discharges the drug from the drug reservoir from the narrowed opening into the lead-out path, moves the drug through the lead-out path toward the drug discharge section, and drops the drug from the drug discharge section. Is desirable.

It can be said that the drug feeder of this embodiment serves the role of the hopper 205 and the role of the trough 210 in the conventional drug feeder in the drug container.
That is, the drug container adopted in this embodiment has a drug storage section for storing the drug, and has a stenotic opening between the drug storage section and the drug discharge section. Therefore, the flow rate of the drug that moves to the drug discharge portion side due to vibration is regulated at the narrowed opening, which creates a trigger for laminar flow.
That is, it can be said that the powdered medicine or the like in the drug container is randomly incorporated in the drug storage section and is in an irregular state in the drug storage section. Then, the drug container receives vibration, and the drug inside tries to move to the drug discharging portion side, but the drug is randomly contained as described above, and the movement of the drug is turbulent.
The drug moves to the stenotic opening, during which time the drug undergoes vibration and changes from a random state to a unidirectionally oriented state. Further, when the drug passes through the stenotic opening, the amount of passage per unit time is regulated, so that the pulsation of the drug flow is suppressed and the drug flow is rectified.
Then, the powdered medicine or the like discharged from the narrowed opening proceeds through the lead-out path. The powdered medicine or the like is rectified as it goes through the lead-out path, laminar flow progresses, and it falls from the drug discharge part in a highly laminarized state.

It is a drug feeder with a weighing function that stops the vibration of the shaking table when the current weight, which is the current weight of the drug container, matches or substantially matches the value obtained by subtracting the target emission amount from the original weight. Is desirable.

As for the means for measuring the weight of the drug container, the measurement of the weight of the drug container may be direct or indirect. That is, only the weight of the drug container may be directly measured, or the weight including the device such as a shaking table may be measured.
In the drug feeder of the present invention, the original weight of the drug container before discharging the drug and the current weight of the drug container are utilized, and the current weight is set to the value obtained by subtracting the target emission amount from the original weight. When they match, the vibration of the shaking table is stopped. Alternatively, in consideration of the weight of the drug in the middle of falling, the vibration of the shaking table is stopped when the current weight is slightly smaller than the value obtained by subtracting the target emission amount from the original weight and substantially matches. Therefore, after the target amount of the drug is discharged, the vibration of the shaking table is stopped and the discharge of the drug is stopped.

It is desirable that the drug feeder can change the vibration pattern of the shaking table.

The drug feeder of this embodiment can vibrate the shaking table with an appropriate vibration pattern according to the properties of the drug and the total discharge amount.

When the drug feeder vibrates the shaking table to discharge a predetermined amount of drug little by little from the drug discharge section, it is desirable that the vibration pattern at the initial stage of discharge and the vibration pattern after that can be different. ..

According to this aspect, in the process of discharging the drug, the vibration pattern can be changed between the initial stage of discharge and the time when the discharge state is stable. Therefore, the drug can be stably discharged.

The drug feeder of this embodiment has a plurality of types of vibration patterns at the initial stage of discharge when a predetermined amount of drug is discharged little by little from the drug discharge section by vibrating the shaking table, depending on the type of drug and / or the total discharge amount. It is desirable that the vibration pattern at the initial stage of discharge is changed.

The drug feeder may have an opening on the upper surface side of the drug container with reference to the posture attached to the main body device, and the drug may be capable of charging the drug into the drug container through the opening.

The drug feeder of this embodiment is suitable for packaging a drug that is infrequently prescribed. The drug feeder of this embodiment is also suitable for packaging a drug that is not suitable for storage in a drug container.

Further, the desirable drug dispensing device includes a container storage unit for storing a plurality of drug containers, the above-mentioned drug feeder, and a container moving means for taking out a predetermined drug container from the container storage unit and placing it on the shaking table of the drug feeder. It is characterized by that.

Hereinafter, embodiments of the present invention will be described, but in embodiments having a shape close to the actual design, the members are intricate and the structure is complicated. Therefore, in order to facilitate the understanding of the invention, the mechanical features and operating principles of the embodiments will be described first. Then, after that, a detailed explanation of specific examples will be given.
The drug feeder 1 of the present embodiment constitutes a part of a powder dispensing device or a drug dispensing device having a powder dispensing function, and as shown in FIG. 1, the vicinity of the distribution dish 212 of the powder distribution device 202. Will be installed in.
The configuration of the drug feeder 1 of the present embodiment is represented by a mechanical diagram as shown in FIGS. 1 to 3. That is, the drug feeder 1 is composed of a drug container 2 and a main body device 3.

Further, the above-mentioned drug container 2 is composed of a container body 5, an iron plate portion 6, and a rectifying member 7.
The container body 5 is a vertically long container made of resin, and one end in the longitudinal direction is open to form a drug discharge section 8.
When the drug container 2 is stored, it is placed in a vertical posture or an inclined posture as shown in FIG. 1, and when it is used, it is placed in a horizontal posture as shown in FIGS. 2 and 3, so that the container body 5 is a drug having an opening surface. The surface facing the discharge unit 8 as a reference is referred to as a bottom surface 10, and the wall surface connecting the drug discharge unit 8 and the bottom surface 10 is referred to as a peripheral wall surface 11. Further, among the peripheral wall surfaces 11, the surface located on the bottom side, particularly when the peripheral wall surface is in a horizontal posture during use, is referred to as the peripheral wall surface lower surface 12.
The container body 5 has a storage space 15 (FIG. 2) surrounded by a bottom surface 10 and a peripheral wall surface 11, and only one surface thereof is an opening surface to form a drug discharge portion 8. Further, a protrusion 16 is provided on the outer peripheral surface side of the container body 5.

The rectifying member 7 is inside the container body 5, and a gap (narrowing opening 13) is formed only between the rectifying member 7 and the lower surface 12 side of the peripheral wall. The rectifying member 7 is inclined so that the end portion on the narrowed opening 13 side faces the inside of the container body 5 (bottom surface 10 side).
The rectifying member 7 is removable from the container body 5. Further, the illustrated rectifying member 7 is only an example, and can be replaced according to the properties of the drug.

In the present embodiment, the inside of the container body 5 is partitioned by the rectifying member 7, and the bottom surface 10 side of the rectifying member 7 functions as the powder storage unit 17. Further, the region on the side of the drug discharge portion 8 with the rectifying member 7 on the lower surface 12 of the peripheral wall as a boundary functions as the lead-out path portion 18.

Next, the main body device 3 will be described.
As shown in FIGS. 1 to 3, the main body device 3 is composed of a vibrating table 20, vibration means 21a and 21b, an intermediate table 22, a vibration isolating table 23, a weight measuring means 25, and a foundation member 26 from above.

Hereinafter, they will be described in sequence. The shaking table 20 is a block-shaped mounting table, and electromagnets 30a and 30b are built in the shaking table 20. That is, the shaking table 20 is provided with magnet mounting holes 28a and 28b, and the electromagnets 30a and 30b are built in the magnet mounting holes 28a and 28b.
Further, the electromagnets 30a and 30b are fixed to the bottoms of the magnet mounting holes 28a and 28b via the elastic bodies 32a and 32b. Therefore, the electromagnets 30a and 30b have a slight degree of freedom with respect to the shaking table 20.
As shown in FIG. 1, the suction portions (tips of the iron cores) 31a and 31b of the electromagnets 30a and 30b are located lower than the upper surface of the shaking table 20.
Further, contact sensors 33a, b, c, d are provided at the four corners of the shaking table 20 on both outer sides of the electromagnets 30a and 30b. Specifically, the contact sensors 33a, b, c, and d are electrodes.
Further, a vibration detection sensor 35 is attached to one side surface of the shaking table 20.

The vibrating means 21a and 21b are piezoelectric elements and have a plate shape.
Although the intermediate table 22 and the anti-vibration table 23 actually have complicated shapes as described later, they are mechanically merely tables, and in FIGS. 1 to 3, they are simply shown in a flat plate shape. There is.
The weight measuring means 25 is a known load cell and has an upper installation surface 36 and a lower installation surface 37, both of which are offset from each other.
Although the foundation member 26 actually has a complicated shape as described later, it is mechanically merely a platform, and is simply shown as a flat plate in FIGS. 1 to 3.

Next, the positional relationship of each component of the main body device 3 will be described. In the main body device 3, as shown in FIGS. 1 to 3, vibration means 21a and 21b are provided between the shaking table 20 and the intermediate table 22. That is, as shown in FIG. 1, the shaking table 20 and the intermediate table 22 face each other, and one end of the shaking table 20 and one end of the intermediate table 22 are connected by the vibrating means 21a. Further, the other end of the shaking table 20 and the other end of the intermediate table 22 are connected by the vibrating means 21b.
In the present embodiment, there is no member other than the above-mentioned vibrating means 21a and 21b that connects between the shaking table 20 and the intermediate table 22. Therefore, the vibrating table 20 has a structure in which the vibrating table 20 is hollowly supported from the intermediate table 22 by the vibrating means 21a and 21b.

A vibration isolation table 23 is arranged below the intermediate table 22, and a vibration isolation member 40 is interposed between the intermediate table 22 and the vibration isolation table 23. The vibration-damping member 40 is a member having both a vibration-damping function and a vibration-damping function, and is a combination of a spring 38 and a vibration-damping rubber (not shown).
In the present embodiment, there is no member other than the vibration-proof member 40 described above that connects between the intermediate table 22 and the vibration-proof table 23. Therefore, the intermediate table 22 has a structure that is hollowly supported from the vibration isolator 23 by the anti-vibration member 40.

Further, a weight measuring means 25 is arranged below the vibration isolator 23, and a foundation member 26 is further arranged below the weight measuring means 25.
In the weight measuring means 25, the upper installation surface 36 is connected to the lower surface of the vibration isolator 23, and the lower installation surface 37 of the weight measuring means 25 is attached to the foundation member 26.
As described above, since the upper installation surface 36 and the lower installation surface 37 are at offset positions, the intermediate portion of the weight measuring means 25 has a structure that is cantilevered with respect to the foundation member 26. The vibration isolator 23 is supported on the free end side.
In the present embodiment, there is no member other than the above-mentioned weight measuring means 25 that connects between the vibration isolator 23 and the foundation member 26. Therefore, the vibration isolator 23 has a structure that is hollowly supported from the foundation member 26 by the weight measuring means 25.

Further, the foundation member 26 is attached in the vicinity of the distribution plate 212 of the powder distribution device 202 via the vibration isolator member 41.
Since the foundation member 26 is a base that supports the entire main body device 3 of the drug feeder 1, the main body device 3 is attached in the vicinity of the distribution dish 212 of the powder distribution device 202.

As described above, the drug feeder 1 of the present embodiment has a structure in which the shaking table 20 is hollowly supported by the vibrating means 21a and 21b. Therefore, when the vibrating means 21a and 21b are vibrated, the vibrating means 21a and 21b are supported. The vibration is conducted to the shaking table 20, and the shaking table 20 vibrates.

Further, in the present embodiment, the weights of the shaking table 20, the vibrating means 21a and 21b, the intermediate table 22 and their accessories are all supported by the vibration isolating table 23. Further, the total weight of the vibration isolator 23 is supported by the upper installation surface 36 of the weight measuring means 25. Therefore, all the weights of the members on the weight measuring means 25 are mechanically applied to the upper installation surface 36 of the weight measuring means 25 as compared with the weight measuring means 25. Therefore, the weight measuring means 25 measures all the weights of the members above the weight measuring means 25. Therefore, in the present embodiment, when the drug container 2 is placed on the shaking table 20, the weight of the drug container 2 is indirectly measured.

Further, as described above, the vibrating table 20 and the vibrating means 21a and 21b generate vibration, but all the members that generate the vibration are mounted on the intermediate table 22, and the intermediate table 22 and the vibration isolating table are mounted. Since the vibration isolator 40 is interposed between the vibration isolator 23, the vibrations of the vibrating table 20 and the vibrating means 21a and 21b are difficult to be transmitted to the vibration isolating table 23.
In the present embodiment, since the weight measuring means 25 is connected to the vibration isolator 23, the weight measuring means 25 is less susceptible to the vibration of the shaking table 20 and the vibrating means 21a and 21b, and has an accurate weight. Can be detected.
That is, in the present embodiment, since the vibration isolating member 40 is provided between the vibration isolating means 21a and 21b and the vibration isolating table 23, the weight measuring means 25 is not easily affected by vibration.
Further, the present embodiment includes an intermediate table 22 and a vibration-proof table 23 that supports the intermediate table 22 via a vibration-proof member 40, and vibration means 21a and 21b and a vibration table 20 are placed on the intermediate table 22. Therefore, the weight measuring means 25 is not easily affected by vibration.

The drug feeder 1 of the present embodiment is composed of the drug container 2 and the main body device 3 as described above, but usually both are separate, and both are combined when the powdered drug is packaged. It constitutes the drug feeder 1.
That is, as described above, the main body device 3 of the drug feeder 1 is fixed in the vicinity of the distribution dish 212 of the powder distribution device 202.
On the other hand, the drug container 2 is placed and stored on a container shelf (not shown) as shown in FIG. That is, the drug container 2 is filled with a predetermined powder, and is placed on a container shelf (not shown) in a vertical posture or an inclined posture (not shown) as shown in FIG. 1, for example.

The drug feeder 1 of the present embodiment constitutes a part of the powder dispensing device (or the overall shape of the drug dispensing device is not shown) as described above, and as shown in FIG. 1, the powder dispensing device 202 It is installed near the distribution plate 212. Another device that constitutes the powder packaging device is a robot (container moving means) 43 that conveys the drug container 2. The robot 43 has an XY table (not shown) and a hand 45 for grasping the drug container 2.
Further, the powder packaging device (the overall shape is not shown) includes a prescription reading means 46 for reading a prescription and a control device 47 for controlling the operation of each device.
The prescription reading means 46 is a device for reading the drug name, prescription amount, and other contents of the prescription drug described on the prescription.

Next, the function of the drug feeder 1 of the present embodiment will be described. Since the drug feeder 1 constitutes a part of the powder packaging device (the overall shape is not shown), the operation of the drug feeder 1 will be described including the operation of the entire powder dispensing device.
In the present embodiment, as described above, the drug container 2 and the main body device 3 are separate, and when the powdered drug is packaged, both are combined to form the drug feeder 1.
That is, in the present embodiment, the drug container 2 is stored in a vertical posture or an inclined posture, and the powder is stored in the powder storage unit 17. In the present embodiment, as shown in FIG. 1, the drug container 2 is grasped by the hand 45 of the robot 43, the drug container 2 is moved, and the drug container 2 is placed on the main body device 3 as shown in FIG.
More specifically, as shown in FIG. 2, the drug container 2 is moved and its posture is changed. That is, the drug container 2 is moved to the vicinity of the main body device 3, and the drug container 2 is laid down in a horizontal posture and placed on the shaking table 20. At this time, as shown in FIG. 2, the posture is such that the lower surface 12 of the peripheral wall is on the bottom. That is, the iron plate portion 6 of the drug container 2 places the drug container 2 on the shaking table 20 in a posture facing the shaking table 20.

Then, the electromagnets 30a and 30b built in the shaking table 20 are energized. As a result, a magnetic force is generated in the electromagnets 30a and 30b, and the iron plate portion 6 of the drug container 2 is attracted to the suction portions (tips of the iron core) 31a and 31b on the shaking table 20 side.
In the present embodiment, the electromagnets 30a and 30b are fixed to the bottoms of the magnet mounting holes 28a and 28b via the elastic bodies 32a and 32b, and the electromagnets 30a and 30b have a slight degree of freedom with respect to the shaking table 20. Therefore, as shown in FIG. 2, the electromagnets 30a and 30b slightly move to the iron plate portion 6 side, and the suction portions 31a and 31b are in close contact with the iron plate portion 6 of the drug container 2.
Further, due to the elasticity of the iron plate portion 6 of the drug container 2 and the shaking table 20 itself, these are slightly deformed and become familiar.
As a result, the iron plate portion 6 of the drug container 2 is in close contact with the surface of the shaking table 20 and the electromagnets 30a and 30b.

Subsequently, in the present embodiment, the degree of adhesion between the drug container 2 and the shaking table 20 and the posture of the drug container 2 are confirmed.
Specifically, if the contact sensors 33a, b, c, d provided around the electromagnets 30a, 30b are energized and there is continuity between the contact sensors 33a, b, c, d, the drug container 2 is used. It is determined that the degree of adhesion of the shaking table 20 and the posture of the drug container 2 are normal. On the contrary, if there is no continuity between the contact sensors 33a, b, c, and d, the degree of adhesion between the drug container 2 and the shaking table 20 is insufficient, or the posture of the drug container 2 is abnormal.

That is, the contact sensors 33a, b, c, d are electrodes exposed on the surface of the shaking table 20. On the other hand, since the iron plate portion 6 is provided on the lower surface surface 12 of the peripheral wall, which is the outer peripheral portion of the drug container 2, if the drug container 2 is in close contact with the shaking table 20 and the posture of the drug container 2 is normal. , The contact sensors 33a, b, c, d are in contact with the iron plate portion 6, and the contact sensors 33a, b, c, d are conducted via the iron plate portion 6.
On the contrary, if there is a problem that the degree of adhesion between the drug container 2 and the shaking table 20 is insufficient, any or all of the contact sensors 33a, b, c, and d do not come into contact with the iron plate portion 6, and the contact sensor Insulation is established between 33a, b, c, and d.

When it is confirmed that there is continuity between the contact sensors 33a, b, c, and d, the shaking table 20 is vibrated. More specifically, the vibrating means 21a and 21b are energized with a current of a constant frequency to generate vibration, and the vibration table 20 is vibrated by this vibration. The amplitude of the shaking table 20 is monitored by the vibration detection sensor 35, and the current frequencies input to the vibrating means 21a and 21b are changed so that the amplitude becomes large.
Further, before and after the start of vibration, the distribution plate 212 of the powder distribution device 202 is rotated.

Further, before and after the start of vibration, the weight of the drug container 2 is measured. The weight of the drug container 2 is obtained by subtracting a constant value from the detected weight of the weight measuring means 25. More specifically, the weight of the drug container 2 is obtained by subtracting the weight of the member above the weight measuring means 25 of the main body device 3 from the detected weight of the weight measuring means 25.
That is, in the weight measuring means 25, the weights of the shaking table 20, the vibrating means 21a and 21b, the intermediate table 22 and their accessories are all supported by the vibration isolating table 23, and the weight measuring means 25 causes the vibration isolating table 23 to be supported. Since the weight is measured, the weight measuring means 25 measures all the weights of the members above the weight measuring means 25.
Therefore, when the drug container 2 is placed on the shaking table 20, the value obtained by adding the weight of the drug container 2 to the weight of the shaking table 20 or the like is detected by the weight measuring means 25.
Since the weight of the shaking table 20 or the like is known here, the weight of the drug container 2 can be indirectly detected by subtracting the weight of the shaking table 20 or the like from the weight detected by the weight measuring means 25.
The weight of the drug container 2 immediately after being installed on the shaking table 20 is stored as the original weight G. Further, the weight of the drug container 2 is constantly monitored. That is, the current weight of the drug container 2 is monitored as the current weight g.

When the shaking table 20 starts to vibrate, the medicine container 2 vibrates. Here, in the present embodiment, the drug container 2 is firmly joined to the shaking table 20 by the electromagnets 30a and 30b, and the degree of adhesion to the shaking table 20 is high. Therefore, the drug container 2 is referred to as the shaking table 20. It vibrates at the same frequency. As a result, the powder stored in the powder storage unit 17 of the drug container 2 slowly moves toward the drug discharge unit 8.
When the shaking table 20 vibrates, the drug container 2 itself receives a force to move in the forward direction. However, in the present embodiment, a protrusion 16 is provided at the rear end portion of the drug container 2, and the protrusion 16 is provided. Is in contact with a part of the shaking table 20 or the like, so that the drug container 2 itself is prevented from advancing. Therefore, the drug container 2 does not move, and only the powder inside moves.

The powder then reaches the constriction opening 13 formed by the site of the rectifying member 7. Since the height of the opening of the stenosis opening 13 is limited, the height of the powder that passes through the stenosis opening 13 is adjusted. That is, the powder flows through the lower surface 12 of the peripheral wall of the drug container 2 as if it were a river, but the height from the lower surface 12 of the peripheral wall to the upper part of the powder is aligned in the width direction.
The powdered drug that has passed through the stenosis opening 13 is discharged to the lead-out path portion 18. Then, the powdered drug flows through the lead-out path portion 18 like the flow of a river, finally reaches the drug discharge section 8 of the drug container 2, falls like a waterfall, and enters the groove 216 of the lower distribution dish 212.

The fact that the powder is falling is confirmed by the decrease in the weight of the drug container 2. That is, in the present embodiment, the current weight of the drug container 2 continues to be monitored as the current weight g even while the powder is falling from the drug discharge section 8 of the drug container 2. Then, the original weight G of the drug container 2 immediately after installation on the shaking table 20 is compared with the current weight g, and the drop amount H (G minus g) of the powder is constantly calculated.

Further, the vibration intensity of the shaking table 20 is fed back so that the falling amount h of the powder per unit time becomes constant. That is, if the amount of fall h per unit time is too small, the frequency of vibration is increased. On the contrary, if the amount of drop is too large, the frequency is lowered. Similarly, the magnitude of the amplitude is also fed back so that the amount of fall h per unit time is constant.
Then, when the total drop amount H of the powder reaches a desired weight, the vibration of the shaking table 20 is stopped.

After that, the rotation of the distribution plate 212 is stopped, the distribution plate 212 is rotated by an angle according to the number of distributions, and the powder is discharged to the outside of the distribution plate 212 by a scraping device (not shown), as in the conventional powder packaging device. It is scraped out and sent to the drug packaging device (not shown) on the subsequent stage.

Next, an embodiment of the present invention having a form closer to the practical design will be described. The chemical feeder 50 described below has a member shape that is significantly different from the mechanical diagram shown in FIG. 1 in order to reduce the overall height, and although the assembly relationship of the parts is complicated, the basic structure of each member and the basic structure of each member and the assembly relationship are complicated. The function is the same as that of the previous embodiment. The components of the drug feeder 50 described below basically have all the functions of the drug feeder 1 described above. for that reason. Members that have different shapes but perform the same function shall be given the same number and name. Further, the description of the members and the like will be mainly described in the parts different from the above-described embodiment, and the overlapping parts will be limited to the schematic description.

The drug feeder 50 having a shape close to the practical design is composed of the drug container 2 and the main body device 3 as in the previous embodiment (FIG. 4).
First, the structure of the drug container 2 will be described. In this embodiment, six types of drug containers 2A, 2B, 2C, 2D, 2E, and 2F are prepared according to the intended use.
That is, the drug container 2A (related invention) of the first form is a type in which the drug discharge section 8 has no lid as shown in FIG. The second form of the drug container 2B (related invention) is a two-sided open type as shown in FIG. 10, and when the drug discharge portion 8 has no lid and is in a horizontal posture, the portion corresponding to the top surface is greatly opened. It is a type that has been used. The third form of the drug container 2C is a closed type as shown in FIG. 12 and has a lid. The fourth form of the drug container 2D is a closed type as shown in FIG. 34 and has a lid. The drug container 2E of the fifth form is a closed type as shown in FIG. 43, has a lid, and has a large lid at a portion corresponding to the top surface and can be opened and closed.

Sequentially described, the drug container 2A of the first form is composed of a container main body 5, an iron plate portion 6, and a rectifying member 7, as shown in FIGS. 5 and 6.
The container body 5 is a vertically long container made of resin, and one end in the longitudinal direction is a drug discharging portion 8.
In the present embodiment, the cross-sectional shape of the container body 5 is a hexagon as shown in FIGS. 5 and 6. That is, the peripheral wall surface 11 of the container body 5 exists on six surfaces including the peripheral wall lower surface 12.
More specifically, the cross-sectional shape of the container body 5 is symmetrical with respect to the state in which the container body 5 is placed horizontally as shown in FIGS. 5 and 6. Then, as shown in FIGS. 5 and 6, there is a peripheral wall upper surface 51 facing the peripheral wall lower surface 12 with the container body 5 placed horizontally as a reference.
Further, as a surface connecting the peripheral wall upper surface 51 and the peripheral wall lower surface 12, there are left and right vertical peripheral walls 52a and b, and left and right inclined peripheral walls 53a and b.
Therefore, based on the state of being placed horizontally as shown in FIGS. 5 and 6, the container body 5 is clockwise from the top, the upper surface 51 of the peripheral wall in the horizontal posture, the right vertical peripheral wall 52b in the vertical posture, and the right in the inclined posture. It has a shape surrounded by a total of six surfaces: an inclined peripheral wall 53b, a lower surface of the peripheral wall in a horizontal posture 12, a left inclined peripheral wall in an inclined posture 53a, and a left vertical peripheral wall in a vertical posture 52a.
Therefore, in the present embodiment, the lower surface 12 of the peripheral wall through which the powder flows is smaller than the other surfaces. Further, in the present embodiment, the powder is easily collected from the other peripheral wall to the lower surface 12 of the peripheral wall.
Also in this embodiment, the protrusion 16 is provided on the outer peripheral surface side of the container body 5. The positions of the protrusions 16 and the like are the same as those in the previous embodiment, and when the container body 5 is in the horizontal posture, the protrusions 16 project downward.

The iron plate portion 6 is formed into a shape that matches a part of the peripheral wall lower surface 12 and the left and right inclined peripheral walls 53a and b.
That is, as shown in FIG. 6, the cross-sectional shape of the iron plate portion 6 is symmetrical, has a flat peripheral wall lower surface contact portion 55, and has inclined peripheral wall contact portions 56a and b on both sides thereof.
There is a certain angle between the peripheral wall lower surface contact portion 55 and the inclined peripheral wall contact portions 56a and b, and this angle is between the peripheral wall lower surface 12 of the container body 5 and the left and right inclined peripheral walls 53a and b. Is equal to the angle of.
The iron plate portion 6 is adhered to a portion on the outer peripheral surface side of the container body 5 and corresponding to the peripheral wall lower surface 12.

As shown in FIG. 8, the rectifying member 7 is formed of a resin and is provided with a substantially square closing plate portion 57, a first comb-shaped portion 58, and a second comb-shaped portion 60. ..
The first comb-shaped portion 58 extends in an oblique direction from the vicinity of the lower side of the closing plate portion 57, and the free end side is divided into a plurality of parts to form a comb shape.
The second comb-shaped portion 60 extends diagonally rearward from the back surface of the closing plate portion 57, and the free end side is divided into a plurality of parts to form a comb shape.

The rectifying member 7 is inside the container body 5 as shown in FIGS. 5 and 7, and the free end side of the comb-shaped portions 58 and 60 is inclined toward the bottom surface 10. That is, the comb-shaped portions 58 and 60 of the rectifying member 7 are inclined so that the free end side is the inner side of the container body 5.
As shown in FIG. 7, a narrowing opening 13 is formed between the free end of the first comb-shaped portion 58 and the lower surface surface of the peripheral wall 12 and between the free end of the second comb-shaped portion 60 and the lower surface of the peripheral wall 12. The first and second comb-shaped portions 58 and 60 are inclined so that the end portion on the narrowed opening 13 side faces the inner side (bottom surface 10 side) of the container body 5.
Also in this embodiment, the inside of the container body 5 is partitioned by the rectifying member 7, and the bottom surface 10 side of the rectifying member 7 functions as the powder storage unit 17. Further, the region on the side of the drug discharge portion 8 with the rectifying member 7 on the lower surface 12 of the peripheral wall as a boundary functions as the lead-out path portion 18.

Next, a modified example of the drug container 2 will be described. In the explanation of each modification described below, B, C, D, E, and F shall be added to the same number for the members common to the drug container 2A described above and the parts exhibiting the common functions. Therefore, a detailed description will be omitted.
The second form of the drug container 2B will be described with reference to FIGS. 9 and 10. As shown in FIG. 10, the drug container 2B is a two-sided open type, and is a type in which a portion corresponding to the top surface is greatly opened when the drug discharge portion 8 is in a horizontal posture without a lid. That is, it can be said that the drug container 2B has the upper side of the drug container 2A of the first form removed. More simply, the drug container 2B lacks a portion corresponding to the upper surface 51 (FIG. 6) of the peripheral wall.
The drug container 2B is composed of a container body 5B, an iron plate portion 6B, and a rectifying member 7B, as in the case of the drug container 2A of the first aspect described above.
The container body 5B is a vertically long and gutter-shaped container made of resin, and one end in the longitudinal direction is a drug discharge portion 8B.
In the present embodiment, the peripheral wall surface 11B of the container body 5B exists on five surfaces including the peripheral wall lower surface 12B.
More specifically, the cross-sectional shape of the container body 5B is symmetrical with respect to the state in which the container body 5B is placed horizontally as shown in FIG. Then, the side facing the lower surface 12B of the peripheral wall is open based on the state in which the container body 5B is placed horizontally as shown in FIGS. 9 and 10.
Also in this embodiment, the protrusion 16B is provided on the outer peripheral surface side of the container body 5B. The position of the protrusion 16B and the like are the same as those of the previous embodiment, and when the container body 5B is in the horizontal posture, the protrusion 16B protrudes downward.

The iron plate portion 6B has the same shape as the iron plate portion 6 of the drug container 2A of the first embodiment described above, and is formed into a shape that matches the peripheral wall lower surface 12B and the like.
The iron plate portion 6B is adhered to a portion on the outer peripheral surface side of the container body 5B and corresponding to the peripheral wall lower surface 12B.

The main part of the rectifying member 7B is the same as that adopted in the drug container 2A of the first form described above, and the closing plate portion 57B, the first comb-shaped portion 58B, and the second comb-shaped portion (second comb) are used. The shape part does not appear in the drawing). However, the total height of the closing plate portion 57B is lower than that adopted in the above-mentioned first-form drug container 2A.

Next, the third form of the drug container 2C will be described with reference to FIG. The drug container 2C is a closed type, and a lid member 120 is provided on the container body 5C.
That is, the drug container 2C is composed of a container body 5C, an iron plate portion 6C, and a lid member 120. Further, in the drug container 2C, a rectifying unit 7C (FIG. 13) is integrally provided on the rear end side of the lid member 120. The rectifying unit 7C has the same function as the rectifying members 7A and 7B described above, but is referred to as a rectifying unit 7C because it is a part of the lid member 120 as described later.
Further, the drug container 2C includes a transport iron plate portion 157.
The container body 5C is a vertically long container made of resin, and one end in the longitudinal direction is a drug discharging portion 8C. In the present embodiment, the cross-sectional shape of the container body 5C is a hexagon as shown in FIGS. 11, 12, and 13. That is, the peripheral wall surface 11C of the container body 5C exists on six surfaces including the peripheral wall lower surface 12C.
More specifically, the cross-sectional shape of the container body 5C is symmetrical with respect to the state in which the container body 5C is placed horizontally as shown in FIG. Then, as shown in FIG. 13, there is a peripheral wall upper surface 51C facing the peripheral wall lower surface 12C with reference to a state in which the container body 5C is placed horizontally.

That is, the ridge 80 has a top surface 81 and vertical walls 82a and b hanging from both sides of the top surface 81 when viewed from the inside.
Further, flange portions 88a and b are provided at the open end of the ridge 80 along both sides thereof. That is, the lower ends of the vertical walls 82a and b are bent outward from each other to form the flange portions 88a and b. Both the flange portions 88a and b have a long plate shape, and the length thereof is longer than that of the ridge 80. That is, both ends of the flange portions 88a and b are further outside from both ends in the longitudinal direction of the ridge 80.
The protruding portions at both ends of the flange portions 88a and b function as intermediate base support portions 83a, b, c and d.

The positional relationship of each part of the anti-vibration table 23 corresponds to that of the intermediate table 22 described above. That is, the ridge 80 provided in the center of the anti-vibration table 23 has a size and a positional relationship that fits in the hollow portion 75 of the intermediate table 22.
Further, the positions of the four intermediate table support portions 83a, b, c, d of the vibration isolation table 23 correspond to the four protrusions 77a, b, c, d of the intermediate table 22.

The foundation member 26 has a quadrangular flat plate portion 97, and the four corner portions thereof are cut up to form spring support portions 90a, b, c, d.

Next, the positional relationship of each component of the main body device 3 of the present embodiment will be described. In the main body device 3, vibration means 21a and 21b are provided between the shaking table 20 and the intermediate table 22 as shown in FIGS. 19, 20, 24 and 25.
In the present embodiment, the connecting plates 91a and 91b are interposed between the vibrating table 20 and the vibrating means 21a and 21b, and the connecting pieces 72a and the vibrating table of the vibrating means 21a and 21b are interposed via the connecting plates 91a and 91b. 20 is attached.
On the other hand, the intermediate table 22 and the vibrating means 21a and 21b are directly connected.
In the present embodiment, both the shaking table 20 and the intermediate table 22 have inclined surfaces 67a, b and inclined surfaces 78a, b, and the vibrating means 21a, 21b have the inclined surfaces 67a, b, inclined surfaces 78a, b of both. It is attached to.

More specifically, the connection piece 72a on the upper side of the vibration means 21a and 21b and the connection plates 91a and 91b are sandwiched between the two pressing blocks 93a and b, and the screw 99a is inserted between them. The vibrating means 21a and 21b and the connecting plates 91a and 91b are fixed.
Further, the connection plates 91a and 91b are in contact with the inclined surfaces 67a and b of the shaking table 20, and are attached to the inclined surfaces 67a and b of the shaking table 20 by the holding block 93c and the screw 99b.

On the other hand, on the lower side of the vibrating means 21a, 21b, the connection piece 72b is in contact with the inclined surface 78a, b of the intermediate table 22, and is attached to the inclined surface 78a, b of the intermediate table 22 by the pressing block 93d and the screw 99c. Has been done.

In the present embodiment, the vibrating means 21a and 21b exist between the shaking table 20 and the intermediate table 22, and the shaking table 20 is not supported at a portion other than the vibrating means 21a and 21b. Therefore, the vibrating table 20 has a structure in which the vibrating table 20 is hollowly supported from the intermediate table 22 by the vibrating means 21a and 21b.

A vibration isolation table 23 is arranged below the intermediate table 22. Explaining the positional relationship between the two, as shown in FIGS. 22, 23, 24, the ridge 80 provided in the center of the vibration isolator 23 has entered the cavity 75 of the intermediate table 22. However, the top surface 81 of the ridge 80 and the inner surface of the cavity 75 of the intermediate table 22 are not in contact with each other. That is, although the intermediate table 22 and the anti-vibration table 23 are intricate, they are mechanically the same as the structure shown in FIG. 1, and the top surface 81 of the ridge 80 and the inner surface of the hollow portion 75 of the intermediate table 22 are in contact with each other. Not.

Further, there are intermediate base support portions 83a, b, c, d of the vibration isolator 23 directly under the four protrusions 77a, b, c, d of the intermediate base 22, and both are connected by a vibration isolator 40. ing.
The vibration-damping member 40 is a member having both a vibration-damping function and a vibration-damping function, and is a combination of a spring 38 and a vibration-damping rubber 96 as shown in the figure.
That is, the four protrusions 77a, b, c, and d of the intermediate table 22 are provided with a round hole 85 that opens downward as shown in FIG. 23, and most of the spring 38 is the intermediate table 22. It has entered the round hole 85.
In the present embodiment, there is no member other than the vibration-proof member 40 described above that connects between the intermediate table 22 and the vibration-proof table 23. Therefore, the intermediate table 22 has a structure that is hollowly supported from the vibration isolator 23 by the anti-vibration member 40.
As described above, although the intermediate table 22 and the anti-vibration table 23 are intricate, the structure is mechanically the same as that shown in FIG. 1, and the intermediate table 22 is hollowed out from the anti-vibration table 23 by the anti-vibration member 40. It has a supported structure.

Further, a weight measuring means 25 is arranged at the lower part of the vibration isolator 23 as shown in FIGS. 22, 23, 24, and a foundation member 26 is further arranged under the weight measuring means 25.
Most of the weight measuring means 25 is located in the ridge 80 provided in the center of the vibration isolator 23 as shown in FIGS. 22, 24, 25, and the upper installation surface 36 of the weight measuring means 25 is vibration-proof. It is connected to the inner surface of the top surface 81 of the ridge 80 of the table 23.
On the other hand, the lower installation surface 37 of the weight measuring means 25 is attached to the foundation member 26.
As described above, since the upper installation surface 36 and the lower installation surface 37 are at offset positions, the intermediate portion of the weight measuring means 25 has a structure that is cantilevered with respect to the foundation member 26. The vibration isolator 23 is supported on the free end side.
In the present embodiment, most of the weight measuring means 25 is contained inside the vibration isolator 23 and the intermediate table 22, and although they have a complicated positional relationship, they are mechanically the same as the structure shown in FIG. The intermediate portion of the weight measuring means 25 has a structure that is cantilevered with respect to the foundation member 26, and the vibration isolator 23 is supported on the free end side thereof.

In the present embodiment, there is no member other than the above-mentioned weight measuring means 25 that connects between the vibration isolator 23 and the foundation member 26. Therefore, the vibration isolator 23 has a structure that is hollowly supported from the foundation member 26 by the weight measuring means 25.
Further, in the present embodiment, most of the weight measuring means 25 is located in the ridge 80 provided in the center of the vibration isolator 23 as shown in FIGS. 24 and 25, and is in the center of the vibration isolator 23. Since the ridge 80 provided in the intermediate table 22 is located in the hollow portion 75 of the intermediate table 22, it can be said that most of the weight measuring means 25 is contained in the intermediate table 22 in relation to the height direction.
Therefore, in the present embodiment, the height of the weight measuring means 25 has a small influence on the total height of the main body device 3, and the total height of the main body device 3 is low.

Further, the foundation member 26 is attached in the vicinity of the distribution dish 212 of the powder distribution device 202 via the vibration isolator 41 as in the previous embodiment.
That is, the four corners of the foundation member 26 are cut up to form the spring support portions 90a, b, c, d (FIG. 19), and the lower surfaces of the spring support portions 90a, b, c, d and the powder are powdered. The base of the packaging device 202 and the like are attached via the vibration isolator 41. The anti-vibration member 41 is composed of a spring 84 (FIG. 20) and an anti-vibration rubber (not shown).

Next, the function of the drug feeder 50 of the present embodiment will be described.
The function of the drug feeder 50 is almost the same as that of the drug feeder 1 described above, and the electromagnets 30a and 30b built in the shaking table 20 are energized to fix the drug containers 2A, 2B, 2C, 2D and 2E to the shaking table 20. Then, the drug containers 2A, 2B, 2C, 2D, and 2E are vibrated to discharge the powder. Hereinafter, a case where the drug container 2C (FIG. 12) is used will be described as an example. That is, a case where a drug container 2C having a third form lid is used will be described as an example.
Also in this embodiment, the drug container 2C is fixed to the shaking table 20 by the magnetic force of the electromagnets 30a and 30b. Here, the drug container 2C has a step portion 121 on the drug discharge portion 8 side as shown in FIG. 11, and the peripheral wall lower surface 12C is divided into an upper step portion 123 and a lower step portion 122 with the step portion 121 as a boundary. The iron plate portion 6C is adhered to a portion on the outer peripheral surface side of the container body 5C and corresponding to the upper portion 123 of the peripheral wall lower surface 12C.
Therefore, in the present embodiment, as shown in FIG. 11, the upper portion 123 of the peripheral wall lower surface 12C of the container body 5C in the drug container 2C is fixed to the shaking table 20 by the magnetic force of the electromagnets 30a and 30b (FIG. 2).
Further, since the shape of the drug container 2C and the shape of the shaking table 20 are different from those of the previous embodiment, the drug container 2C behaves peculiarly.

That is, also in this embodiment, the drug container 2C is transported by the hand of the robot (not shown) or the like.
When being transported, the drug container 2C is changed from the initial vertical posture to the horizontal posture as shown in FIGS. 11 and 26 (a), and is close to the main body device 3.
At this time, the robot 43 of FIG. 1 controls the posture of the hand 45 so that the axis BC of the drug container 2C and the axis MC of the main body device 3 match as much as possible, but it is difficult to always completely match them. Therefore, as shown in FIG. 26 (b), the two may be misaligned.

The drug container 2C is installed on the shaking table 20 in a state where the axis BC of the drug container 2C and the axis MC of the main body device 3 are displaced. In the present embodiment, the iron plate provided near the bottom of the drug container 2C is provided. The portion 6C has inclined peripheral wall contact portions 56aC and 56bC, which are substantially tapered.
On the other hand, the shaking table 20 is also provided with an edge portion 66 on the mounting surface 61 as described above, and has a substantially tapered shape.
Therefore, when the drug container 2C is installed on the shaking table 20, it is guided by the taper, and the inclined peripheral wall contact portions 56aC and 56bC on the drug container 2C side coincide with the inclined surface 68 of the shaking table 20 as shown in FIG. It tends to be.

In addition, in the present embodiment, the protrusion 16C is provided near the rear end of the drug container 2C. On the other hand, in the drug feeder 50 of the present embodiment, there is a fitting recess 108 between the sensor holding portion 69 of the sensor bracket 70 and the short side side surface 63b of the shaking table 20. Therefore, in the present embodiment, when the drug container 2C is installed on the shaking table 20, the protrusion 16C of the drug container 2C fits with the fitting recess 108 on the main body device 3 side.

Therefore, the posture of the drug container 2C is corrected, and the axis BC of the drug container 2C and the axis MC of the main body device 3 come close to each other as shown in FIG. 27 (b). However, the inclined peripheral wall contact portions 56aC and 56bC of the drug container 2C and the inclined surface 68 of the shaking table 20 do not completely match, and as shown in FIG. 27 (a), the inclined peripheral wall contact portions 56aC of the drug container 2C, In some cases, a portion D where 56bC and the inclined surface 68 of the shaking table 20 do not match may be formed. In this case, as shown in FIG. 27 (b), the axis BC of the drug container 2C and the axis MC of the main body device 3 are slightly deviated from each other.

When the electromagnets 30a and b are energized in this state, the flat peripheral wall lower surface contact portion 55C provided on the peripheral wall lower surface 12C of the drug container 2C is attracted to the electromagnets 30a and b, and the peripheral wall lower surface contact portion 55C vibrates. It is attracted to the table 20 side, and the peripheral wall lower surface contact portion 55C is brought into close contact with the mounting surface 61 of the shaking table 20. Then, the tapered shapes of the drug container 2C and the shaking table 20 match due to the force received at that time, and the axis BC of the drug container 2C and the axis MC of the main body device 3 match as shown in FIG. 28 (b).

Further, since the peripheral wall lower surface contact portion 55C of the drug container 2C is in close contact with the mounting surface 61 of the shaking table 20, the horizontal posture of the drug container 2C is also ensured.

In this embodiment, the degree of adhesion between the drug container 2C and the shaking table 20 and the posture of the drug container 2C are provided on the condition that the contact sensors 33a, b, c, d provided at the four corners of the mounting surface 61 are electrically connected to each other. Is judged to be normal.

Also in the drug feeder 50 of the present embodiment, after the drug container 2C is fixed to the shaking table 20, the drug container 2C is vibrated to discharge the powder, and at this time, the drug container 2C also receives a force in the forward direction due to the vibration. However, in the drug feeder 50 of the present embodiment, since the protrusion 16C of the drug container 2C provided at the rear end of the drug container 2C is fitted with the fitting recess 108 on the main body device 3 side, the drug container 2C itself. Does not move in the axial direction.

Further, in the present embodiment, when the drug in the drug container 2C advances toward the drug discharge portion 8C, the drug passes through the comb-shaped 142 portion of the inclined plate portion 141 shown in FIG. 16 and the rectifying coil 126. It crosses the rectifying coil 126 and passes through the gap between the lines. Therefore, the flow of the drug is smoothed. Further, even if a lump of the drug is present, the lump collapses when passing through the comb-shaped portion 142 and the rectifying coil 126, and returns to the powder shape.

The operation of the drug feeder 50 has been described above by taking the case of using the drug container 2C of the third form as an example, but the same operation is performed even if the drug container 2D of the fourth form is used.
However, when the fourth form of the drug container 2D (FIG. 34) is used instead of the third form of the drug container 2C, there is an effect that the drug previously filled in the drug container 2D is preferentially discharged.
In the drug container 2D of the fourth form, since the lid member 120D is removed and the drug is filled inside, the drug is charged in a vertical posture. Therefore, the charged drug is deposited from the bottom surface 10D side of the container body 5D.
On the other hand, when discharging the drug, the drug container 2D is laid down in a horizontal position as shown in FIG. 42. Here, in the drug container 2D of the fourth form, the inclined portions 181a and 181b are provided on the inner surface side of the lower surface surface 12D of the peripheral wall and on the inner surface side portion. Therefore, as shown in FIG. 42, the old drug layer 360 previously charged into the drug container 2D and deposited on the bottom surface 10D side of the container body 5D wraps around under the new drug layer 361. Therefore, the drug of the old drug layer 360 is mixed with the drug of the new drug layer 361 and discharged.

Further, as the drug moves by vibration, the drug in the old drug layer 360 flows under the new drug layer 361.
Here, when the two layers of the chemicals move together and reach the position of the comb-shaped rectifying member 130D, the upper side of the two layers is scooped up by the plate-shaped portion 362 of the comb-shaped rectifying member 130D as shown in FIG. 42. Will be. In particular, since the comb-shaped rectifying member 130D is in an inclined posture as a whole, the upper side of the two layers is plowed up at the plate-shaped portion 362 of the comb-shaped rectifying member 130D, and further returned to the bottom surface 10D side as shown by an arrow. .. Therefore, the old drug layer 360 that moves on the lower layer side is preferentially discharged, and the flow of the drug in the drug container 2D in the first-in first-out manner can be realized.

Next, the peripheral device of the drug feeder 50 will be described.
The drug feeder 50 of the present embodiment constitutes a part of the drug dispensing device 100 having a powdered powder packaging function.
The overall structure of the drug dispensing device 100 is as shown in FIG. 30, for example. The drug dispensing device 100 is functionally divided into a drug shelf area 103, a drug dividing area 105, and a drug packaging area 106 in the vertical direction.
A drug container storage shelf 101 is arranged around the uppermost drug shelf region 103, and a drug container moving device 102 is provided inside the drug container storage shelf 101.
The medicine shelf region 103 is dehumidified by a dehumidifying device (not shown). Further, a dust collector (not shown) is provided inside the medicine shelf area 103, and dust in the medicine shelf area 103 is removed. For example, a blower fan is provided in the medicine shelf area 103, and the air in the medicine shelf area 103 is circulated by the blower fan. Then, a filter is provided in a certain ventilation path such as the intake side of the blower fan to remove dust and the like floating in the medicine shelf region 103.

The drug container moving device 102 has a vertical elevating shaft 110, a horizontal moving arm 180, and a hand portion 112 for holding the drug container 2C. The horizontal movement arm 180 has joints 168 and 169 at two locations as shown in FIG. The hand portion 112 can change the posture of the drug container 2C. The drug container moving device 102 employs the hand portion 112 of the electromagnet 170. That is, as shown in FIGS. 30 and 31, an electromagnet 170 is provided at the tip of the horizontal moving arm 180.

A powder distribution device 202 is provided in the drug division region 105. In the present embodiment, the powder distribution device 202 has two distribution plates 212. A plurality of drug feeders 50 of the present embodiment are installed in the powder distribution device 202. In the present embodiment, a plurality of drug feeders 50 are installed in each distribution dish 212. More specifically, three drug feeders 50 are installed in each distribution dish 212. Each drug feeder 50 is attached tangentially to each distribution dish 212. The attachment angle of the drug feeder 50 to each distribution dish 212 is not limited to the tangential direction, but by attaching the drug feeder 50 to each distribution dish 212 in the tangential direction, the distribution accuracy of the drug can be improved. It has a higher effect. Further, when the medicine container 2C is held by the medicine container moving device 102 and the medicine container 2C is fixed to the shaking table 20, or when the medicine container 2C is removed from the shaking table 20, there is little unnecessary operation of the medicine container moving device 102. The effect of becoming can be expected.
The drug packaging device 203 is built in the drug packaging area 106.
Further, the drug dispensing device 100 includes a prescription reading means 46 for reading a prescription and a control device 47 for controlling the operation of each device.

Further, on the outer wall side of the drug packaging area 106, a drug container inlet 151 as shown in FIG. 29 is provided. Inside the drug container inlet 151, a weight measuring means 152 such as a load cell and a reading device (not shown) are provided. As the reading device, a barcode reader, an RFID (Radio Frequency Identification) reader, or the like can be adopted.
When the drug container 2C is set in the drug container inlet 151, the total weight of the drug container 2C is measured internally and stored in the memory of the control device 47. Further, a bar code or the like (not shown) provided on the drug container 2C is read by a bar code reader or the like, and the drug container 2C is transported and stored at a predetermined position in the drug shelf region 103 by the drug container moving device 102.
Here, in the present embodiment, the drug container moving device 102 has a hand portion 112 of the electromagnet 170. In the present embodiment, as shown in FIG. 31, the electromagnet 170 is brought close to the transport iron plate portion 157 of the drug container 2C, and then the electromagnet 170 is energized to attract the transport iron plate portion 157 to hold the drug container 2C. Move it.

It should be noted that a two-sided open type container such as the second form of the drug container 2B (FIG. 9), which has no lid and has a large open portion corresponding to the top surface when in a horizontal posture. When using the container 2B, a drug container that has been separately weighed or unweighed on a dispensing table or the like is charged from the open upper side (upper side when the drug container 2B is in a horizontal position) of the drug container 2B, and then the drug container is used. Set in the slot 151. When the drug container 2B of the second form is set, the total weight of the drug container 2B is measured, stored in the memory of the control device 47, and then directly transported to one of the drug feeders 50 by the drug container moving device 102. Then, an amount of the drug based on the prescription information is dispensed to the powder distribution device 202.

The control of the entire drug dispensing device 100 is generally as shown in the flowchart of FIG. 32.
Hereinafter, the operation of the entire drug dispensing device 100 will be described with reference to the flowchart of FIG. 32.

In the present embodiment, as shown in FIG. 32, all the operations are started by reading the contents of the prescription by the prescription reading means 46.
That is, when the content of the prescription is input in step 1, the process proceeds to step 2, and the work of carrying out the drug container 2C is immediately started. More specifically, the drug container moving device 102 is driven, and the drug container 2 containing the drug matching the prescription is selected from a large number of drug containers 2 arranged in the drug shelf region 103, and the drug is selected. It is installed in the main body device 3 of the feeder 50. At this time, the grip portion 147 of the movable lid portion 134 is pressed by the pressing piece (not shown) to open the movable lid portion 134, and the movable lid portion 134 is opened by the attractive force of the magnet 156 for maintaining the open state. The state is maintained.

Then, in step 3, the electromagnets 30a and 30b are energized, and the drug container 2C is fixed to the shaking table 20.
After that, the process proceeds to step 4, and the timer is started to be timed. This timer defines the time for determining whether or not the drug container 2C is normally installed, and is as short as, for example, about 1 second.
If it is confirmed that all of the contact sensors 33a, b, c, and d are energized by the time the timer finishes timing (YES in step 5), it is determined that the drug container 2C has been installed in the normal posture, and the step is taken. Move to 6. On the other hand, if the contact sensors 33a, b, c, d cannot confirm the contact even after waiting for a certain period of time (step 12), there is a high possibility that there is a foreign substance on the shaking table 20 or the like. , Step 13, and a series of operations are retried. More specifically, the energization of the electromagnets 30a and 30b is stopped, the drug container moving device 102 is driven, the drug container 2C is re-grasped and lifted by the hand portion 112, and the drug container 2C is lifted again by the main body device 3 of the drug feeder 50. And retry the operation after step 3.

When the energization in step 5 is confirmed by the first trial or the second trial and the process proceeds to step 6, the weight measurement of the drug container 2C is started. That is, the original weight G of the drug container 2C is measured and stored, and the current weight g of the drug container 2C is monitored.

Then, the process proceeds to step 7, the vibration of the shaking table 20 is started, and the distribution plate 212 of the powder distribution device 202 is rotated.

Then, the process proceeds to step 8 and the timer is started to be timed. In the following step 9, the weight change of the drug container 2C per fixed time is monitored, and in step 10, a predetermined amount of powder is waited to be dispensed.
That is, the change in the weight of the drug container 2C is monitored, and in step 9, it is confirmed that the weight has continued to decrease by at least a certain amount or more per fixed time. If the weight has been reduced by at least a certain amount for a certain period of time, the medicine has fallen normally from the medicine container 2C. To confirm. If the amount of powdered medicine to be paid out is insufficient, the process returns to step 9. In this way, while confirming the drop of the drug in steps 9 and 10, wait for the predetermined amount of powder to be discharged.
That is, in step 10, it waits for the difference between the original weight G of the drug container 2C and the current weight g to become the desired payout amount. Then, when the desired payout amount is reached, the process proceeds to step 11 to stop the vibration of the shaking table 20.

Subsequent steps are the same as the known drug dispensing device 100, in which the drugs are divided, scraped out, and individually packaged.

Further, if the weight reduction of the drug container 2C is stopped before the desired payout amount is reached, it is expected that the powder drug in the drug container 2C is insufficient because the continuous drop of the powder cannot be confirmed. Then, the process proceeds to step 14, an error display indicating that the powder is insufficient is displayed, and a series of steps is completed.

When the series of discharging steps and packaging steps are completed, the energization of the electromagnet is stopped, and the medicine container moving device 102 is operated to return the medicine container 2C to the original position.
Here, as a peculiar configuration of the drug dispensing device 100 of the present embodiment, the total weight of the drug container 2C is reweighed when the drug container moving device 102 is operated to return the drug container 2C to the original position. More specifically, when the drug container 2C is returned to its original position, the drug container 2C is once carried to the drug container inlet 151, and the drug container 2C is placed on the weight measuring means 152 provided in the drug container inlet 151. And reweigh the total weight of the drug container 2C.

Then, the total weight of the drug container 2C at the beginning (immediately before the current drug discharge) is compared with the total weight of the drug container 2C after the drug is discharged. Then, it is confirmed that the difference between the two matches the amount of the drug discharged during the above-mentioned process. That is, the process of confirming the amount of emissions is carried out.
Alternatively, the weight of the drug container 2C by the weight measuring means 152 provided in the drug container inlet 151 and the weight of the drug container 2C after discharging the drug measured by the drug feeder 50 are compared, and both are matched. Confirm. That is, a verification step is performed to determine whether the weight measuring means 25 of the drug feeder 50 is accurate.
Then, as a result of reweighing the total weight of the drug container 2C, if the total weight of the drug container 2C is normal, the drug container moving device 102 is operated to return the drug container 2C to the original position. If there is an abnormality in the total weight of the drug container 2C, an alarm is immediately issued to notify the pharmacist.

Next, a method of using the drug container 2B of the second form and the drug container 2E of the fifth form, which are two-sided open type, will be described.
The second and fifth forms of the drug containers 2B and 2E are used when manually packaging powders and the like. That is, there are drugs that are rarely used, drugs that are highly toxic, and drugs that are not suitable for storage in the drug container storage shelf 101 of the drug dispensing device 100 because of their high hygroscopicity and weakness to high temperatures. Alternatively, it may be necessary to crush the tablets or capsules before prescribing.
In such a case, the second and fifth forms of the drug containers 2B and 2E are fixed to the shaking table 20 of the drug feeder 50, and a rough amount of the drug is charged into the drug containers 2B and 2E from the opened upper side. do. When the drug container 2E of the fifth form is used, the large lid 301 is removed, the opening 300 is opened, and the drug is charged through the opening 300. After that, the weight of the drug container 2B is measured. That is, the original weight G of the drug containers 2B and 2E is measured and stored, and the current weight g of the drug containers 2B and 2E is monitored.
After that, the vibration table 20 is started to vibrate, and the distribution plate 212 of the powder distribution device 202 is rotated so that the difference between the original weight G of the drug containers 2B and 2E and the current weight g becomes the desired payout amount. wait. Then, when the desired payout amount is reached, the vibration of the shaking table 20 is stopped.

In the embodiment described above, the powder is supplied to the distribution dish 212 of the powder distribution device 202 by using the drug feeders 1, 50, but the powder may be supplied directly from the drug feeders 1, 50 to the drug packaging device 203. good.
It is also conceivable to supply tablets and capsules using the drug feeders 1, 50 of the present invention.

In the embodiment described above, in the drug feeders 1 and 50, the contact sensors 33a, b, c and d are provided at the four corners of the shaking table 20, but the number of contact sensors is arbitrary. However, in order to determine whether or not the shaking table 20 is in close contact with the bottoms of the drug containers 2A, 2B, 2C, 2D, 2E, at least two or more contact sensors are provided in the longitudinal direction of the shaking table 20. It is desirable that it is. Further, in order to confirm that the axes of the drug containers 2A, 2B, 2C, 2D, and 2E coincide with the axes of the shaking table 20, at least two or more contact sensors in the width direction of the shaking table 20 are used. It is desirable that is provided.

In the embodiment described above, the weight of the drug container 2C immediately after installation on the shaking table 20 is stored as the original weight G, the current weight of the drug container 2C is the current weight g, and the difference between the two is the amount of powder discharged. However, the amount of powder discharged may be obtained from the total detected weight of the weight measuring means 25. That is, the weight including the weight of the device such as the shaking table 20, and the detected weight of the weight measuring means 25 immediately after the drug containers 2A, 2B, 2C, 2D, and 2E are installed on the shaking table 20, is the original weight G, and the powder is powdered. The detected weight of the weight measuring means 25 during discharge may be the current weight g, and the difference between the two may be the discharge amount of the powder.

In the embodiment described above, the electromagnets 30a and 30b are adopted as the container holding means, and the configuration in which the drug container 2 is directly adsorbed by the electromagnets 30a and 30b is adopted. That is, in the embodiment described above, the container holding means using the magnetic force is adopted.
However, the present invention is not limited to this configuration, and the drug container 2 may be held by other mechanical means. For example, a configuration in which some engaging member or fitting member is operated by a solenoid, a small motor, an air cylinder, or the like to mechanically hold the drug container 2 can be adopted.

Further, in the above-described embodiment, the electromagnets 30a and 30b are energized to fix the drug container 2 to the shaking table 20, but the drug container 2 is mounted on the shaking table by using a permanent magnet or by using a permanent magnet and an electromagnet in combination. It may be fixed to 20.
Specifically, instead of the electromagnets 30a and 30b, a non-excited electromagnet or a magnet having a structure called a self-holding solenoid is adopted as the container holding means.
The self-holding solenoid and the like described above are a combination of a permanent magnet and an electromagnet, and always exert an attractive force mainly by the permanent magnet. Then, when the magnetized object is separated from the self-holding solenoid or the like, the electromagnet is energized to generate a magnetic force in the direction opposite to that of the permanent magnet.
Alternatively, the electromagnet is energized during adsorption to generate a magnetic force in the same direction as the permanent magnet, and at the time of detachment, a current in the opposite direction is passed to generate a magnetic force in the direction opposite to that of the permanent magnet.

Since the shapes of the electromagnets 30a and 30b and the self-holding solenoid are similar, the shape of the main body device 3 is the same as that of FIGS. 19 to 25 described above even when the self-holding solenoid is adopted. The container holding means will be described as the self-holding solenoids 30a and 30b with reference to FIGS. 19 to 25 and 32.
When the self-holding solenoids 30a and 30b are used, the self-holding solenoids 30a and 30b are energized to suppress the generation of magnetic force when the carrying-out work of the drug container 2 is started in step 2 described above.
Then, as in the previous embodiment, the work of carrying out the drug container 2 is started. A drug container 2C containing a drug matching the prescription is selected from a large number of drug containers 2 and installed in the main body device 3 of the drug feeder 50.

Then, the energization of the self-holding solenoids 30a and 30b is stopped, and the magnetic force of the permanent magnet is exerted to fix the drug container 2 to the shaking table 20.
The following steps are the same as those in the above-described embodiment, but when the drug container 2 is separated from the shaking table 20, the self-holding solenoids 30a and 30b are energized again to cancel the magnetic force of the permanent magnet.
Since the self-holding solenoids 30a and 30b maintain the attractive force in a non-energized state, the power consumption is smaller than that of the configuration using the electromagnets 30a and 30b. In that respect, the configuration using the self-holding solenoids 30a and 30b is superior to the configuration using the electromagnets 30a and 30b.
Further, the self-holding solenoids 30a and 30b consume less power and generate less heat. Therefore, it is also recommended because it has a small effect on the drug in the drug container 2.

In the embodiment described above, the protrusion 16C is provided on the drug container 2C side to engage with the main body device 3 side to prevent the drug container 2C from advancing, but the protrusion is provided on the main body device 3 side to prevent the drug container 2C from advancing. , 2B, 2C, 2D, 2E It is also effective to engage with a part of the side or to provide a recess in the drug container 2.

In the embodiment described above, as the vibration-proofing members 40 and 41, a combination of a spring and a vibration-damping rubber is exemplified, but a vibration-damping member made of a single spring may be adopted and is made of only resin or the like. A vibration-proof member may be adopted.

In the embodiment described above, the vibration isolator 40 is provided between the intermediate table 22 and the vibration isolation table 23 to prevent vibration from being transmitted to the vibration isolation table 23, but in addition to this configuration or this configuration. Instead, it is also recommended to remove the effects of vibration by software. For example, a method of Fourier transforming the detected value of the weight measuring means 25 to remove the influence of vibration can be considered.

In the embodiment described above, the total weight of the drug container 2C is reweighed by using the weight measuring means 152 provided in the drug container inlet 151, but the weight measuring means is provided in another portion of the drug container 2C. The total weight may be reweighed. Further, the drug container 2C may be remounted from the drug feeder 1,50 used for discharging the drug to another drug feeder 1,50, and the total weight may be reweighed. That is, if it is found that there is some abnormality in the measured value by reweighing, it also leads to detecting the failure of any of the compared weight measuring means 25 and 152.
Further, the step of reweighing is not essential and may be omitted.

In the embodiment described above, a configuration is adopted in which the vibration of the shaking table 20 is stopped after the difference between the original weight G of the drug container 2C and the current weight g reaches the desired payout amount, but in consideration of the time lag. It is also recommended to stop the vibration of the shaking table 20 in a state where the difference between the original weight G and the current weight g is slightly smaller than the desired payout amount.

Further, in the embodiment described above, the weight of the drug container 2C is monitored to decrease and it is confirmed that the drug continues to fall. However, a powder drop sensor is separately provided and the powder drop sensor is used. You may want to make sure that the drug continues to fall.

In the embodiment described above, as the container moving means, one having a hand 45 (FIG. 1) of a type that grips the drug container 2 and one having a hand portion 112 (FIG. 30) using an electromagnet are adopted. In the former hand 45, the hand 45 itself operates independently of the arm. In the latter hand portion 112, the hand portion 112 itself is integrated with the arm and does not operate relative to each other, and holds the drug container 2 by physical adsorption.
Alternatively, a hand holding the drug container 2 by physical fitting or engagement can be considered.
For example, as in the combination of the drug container 2F shown in FIG. 33 and the hand 172, they are engaged by moving each other relative to each other.
That is, as shown in FIG. 33, the drug container 2F is provided with a guide rail 173 on the peripheral wall upper surface 51D. The guide rail 173 has engagement grooves 174 on both sides.
One hand 172 is provided with a groove 175 having a "C" cross-sectional shape. The tip side of the groove 175 in the longitudinal direction is open as shown in the figure. Further, the rear end of the groove 175 in the longitudinal direction is closed (not shown).
The cross-sectional shape of the groove 175 of the hand 172 is similar to the cross-sectional shape of the guide rail 173, and both can be engaged. In the engaged state, both can move only linearly and are separated from each other. You can't.
The hand 172 is integrally attached to the robot arm.

When the drug container 2F is held by the hand 172 shown in FIG. 33, the robot arm is operated to bring the hand 172 closer to the drug container 2F, and the end of the guide rail 173 is aligned with the open end of the groove 175. Then, the robot arm is linearly moved to insert the guide rail 173 into the groove 175. As a result, the drug container 2F has a degree of freedom only in the direction along the guide rail 173, and is substantially held by the hand 172.

Further, the main body device 3 has members for energizing such as electromagnets 30a and 30b, self-holding solenoids 30a and 30b, and vibration means (piezoelectric element), and easily generates heat. When there is a concern that the heat generated may affect the drug in the drug container 2, it is desirable to provide a cooling means for cooling the main body device 3.
As an example of the cooling means, as shown in FIG. 46, a configuration in which a cooling fin 305 is provided in the main body device 3 or a blower 306 is provided in the vicinity thereof can be considered.

Further, as a more developed configuration, a configuration in which the vibration pattern of the shaking table 20 can be changed according to the drug type, the discharge timing, and the total discharge amount is recommended.
The particle size and hygroscopicity of the drug vary depending on the type. Therefore, when the shaking table 20 is vibrated, the behavior of the drug in the drug container 2 differs depending on the drug.
There are chemicals that are easily rectified and flow when subjected to vibration, and chemicals that are difficult to rectify. The amount of movement in one vibration differs depending on the type of drug.
In addition, there is a problem that the amount of drug discharged is not stable at the initial stage of drug discharge.

Therefore, the frequency (frequency) per unit time and the magnitude of the amplitude can be changed, and the magnitude of the frequency and the amplitude can be changed according to the drug type, the discharge time, and the total discharge amount.
For example, the ease of discharging a drug is tested in advance, and all the drugs scheduled to be discharged are classified into a plurality of stages by the drug feeders 1, 50. This is referred to as, for example, a “flow coefficient”, and the drug is classified from the flow coefficient 1 to the flow coefficient 3.
In addition, the emission level is divided into multiple stages according to the total emission of the drug. For example, the emission amount is divided into 20 grams, and is referred to as "emission amount 20, emission amount 40, emission amount 60".
In addition, the vibration level is divided into multiple stages according to the frequency and amplitude of the vibration. This is referred to as, for example, "vibration level 1, vibration level 2", and it is assumed that the vibration level can be changed from vibration level 1 (minimum vibration) to vibration level 20 (maximum vibration), for example.

Then, an appropriate vibration level is selected according to the "flow coefficient" and "emission amount". The vibration level distinguishes between the vibration level in the initial stage of discharge and the vibration level in the stable period.
For example, if the drug is easily discharged such as "flow coefficient 1" and the total discharge amount is small such as "discharge amount 20", vibration is started with slow vibration such as vibration level 3. After a certain period of time, the vibration is switched to a stronger vibration such as a vibration level 10. Alternatively, the system is switched to a method in which the vibration intensity of the shaking table 20 is feedback-controlled so that the emission amount h per unit time becomes constant, centering on a strong vibration such as a vibration level 10.

In addition, when the drug is difficult to be discharged such as "flow coefficient 3" and the total discharge amount is large such as discharge amount 80, vibration is started with strong vibration such as vibration level 11 for a certain period of time. After that, it switches to a stronger vibration such as vibration level 15. Alternatively, feedback control is performed so that the emission amount h per unit time becomes constant, centering on a strong vibration such as a vibration level 15.

Further, it is desirable to provide a verification function for verifying whether or not the weight measuring means 25 of the drug feeders 1 and 50 is accurate.
For example, a weight member having a known weight is prepared, and the weight is installed in the medicine shelf area 103 or the like. Then, the weight member is moved to the shaking table 20 by the robot 43 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 accurate, and if not, the weight measuring means 25 is out of order.
Further, the drug container 2 itself can be utilized as the weight member. For example, harmless powder or granules are placed in the drug container 2 and the weight thereof is measured in advance. The drug container 2 used as a weight member is installed in the drug shelf area 103 or the like together with other drug containers 2. Then, if necessary, the drug container 2 for the weight is moved by the robot 43 or the like, installed on the shaking table 20, and the weight measuring means 25 is verified.

The measure for installing the drug container 2 in the drug shelf region 103 is arbitrary, but for example, as shown in FIG. 47, a drug shelf 328 provided with a plurality of vertical walls 320 and a mounting table 323 can be considered. The vertical wall 320 is provided with an upper engaging portion 325, and the mounting table 323 is provided with a lower engaging portion 326. The upper engaging portion 325 and the lower engaging portion 326 are maintained in a protruding state by an urging member (not shown).
In the drug container 2 to be adopted in the present embodiment, in addition to the configuration of the drug container 2D of the fourth embodiment, the lid member 120D is provided with an engaging protrusion 370. Further, there is a dent 371 at the rear end of the drug container 2D.
The upper engaging portion 325 rotates upward as shown by an arrow by pressing the lid member 120D of the drug container 2D. The lower engaging portion 326 is submerged in the mounting table 323 by pressing the iron plate portion 6 of the drug container 2.
When the drug container 2D is pressed against the drug shelf 328, the upper engaging portion 325 and the lower engaging portion 326 escape against the force of the urging member. Then, when the drug container 2D reaches a predetermined position, the upper engaging portion 325 is restored by an urging member (not shown) and engages with the engaging projection 370 of the lid member 120D. Further, the lower engaging portion 326 is restored by an urging member (not shown) and engages with the recess 371 at the rear end portion of the drug container 2D.
When taking out the medicine container 2D, the medicine container 2D is held by a robot 43 or the like and separated from the medicine shelf 328. At that time, the upper engaging portion 325 and the lower engaging portion 326 escape against the force of the urging member, and the engagement is released.

Further, for example, as shown in FIG. 48, a drug shelf 345 provided with a plurality of vertical walls 340 and a mounting table 343 can be considered. The vertical wall 340 has an opening 346, and a protrusion (upper engaging portion on the storage portion side) 347 projects upward in the opening 346.
Further, the mounting table 343 is provided with a lower engaging portion 348 on the storage portion side. The lower engaging portion 348 on the storage portion side is a protrusion.
In the present embodiment, the drug container 2 to be adopted has a recess 350 at the rear end like the drug container 2D of the fourth embodiment. A container-side engaging portion 352 is provided on the lower surface 12D of the peripheral wall of the container body 5D. The position of the container-side engaging portion 352 is the lower surface 12D of the peripheral wall, which is slightly closer to the lid member 120D than the center, and does not hit the shaking table 20 when the drug container 2D is installed on the shaking table 20. The container-side engaging portion 352 has a ring shape and is provided with a square hole 351 penetrating in the longitudinal direction of the drug container 2D.

In the present embodiment, the container-side engaging portion 352 of the drug container 2D is inserted through the opening 346, the drug container 2D is pushed down, and the protrusion of the drug shelf 345 (the upper part of the storage section side) is inserted into the hole 351 of the container-side engaging portion 352. The drug container 2D is suspended from the drug shelf 345 by inserting the joint portion 347.
At this time, the protrusion (lower engagement portion on the storage portion side) 348 provided on the mounting table 343 engages with the recess 350 of the drug container 2.

Among the drug containers 2 described above, in the drug container 2 having a lid, in principle, the drug is charged by removing the lid member 120, but the fifth form of the drug container 2E has a movable lid portion 134E. Since it is easy to remove the drug, it is possible to add the drug without removing the lid main body 125E. In that case, as shown in FIG. 45, if the funnel-shaped member 355 is attached to the portion of the movable lid portion 134E and the work is performed, the drug does not easily spill.
