Description

The present invention relates to a medicine feeder for taking out a medicine by weighing a predetermined amount. The medicine feeder of the present invention is suitably used as a device for supplying powder to a powder dispensing device for dispensing powder. Moreover, the medicine feeder of the present invention is suitable as a device incorporated in a powder medicine packaging device having a function of distributing powder by the powder dispensing device and individually packaging the powder.
The present invention also relates to a medicine dispensing device incorporating a medicine feeder.

In recent years, large hospitals and large-scale pharmacies have introduced powder dispensing devices and drug dispensing devices having a powder dispensing function. Here, the powder medicine packaging device is an apparatus for individually packaging powder medicine or the like for each dose. If the powder medicine packaging device is used, it is possible to automate most of the work of packaging powder medicines one by one.
The powder medicine packaging apparatus 200 disclosed in Patent Literature 1 is an apparatus for individually packaging powder medicines for each dose. As shown in FIG. 49, the medicine supply apparatus 201, the powder distribution apparatus 202, and the medicine packaging are contained therein. Device 203.
As shown in FIGS. 49 and 50, the medicine supply device 201 disclosed in Patent Document 1 includes an input hopper 205 and a powder feeder 206.
As shown in FIG. 50, the powder feeder 206 is provided with two piezoelectric elements 207 and 208 under the trough 210, and vibrates the trough 210.

As shown in FIG. 49, the powder distribution device 202 includes a distribution tray 212 and a scraping device 215. The distribution tray 212 has an arc-shaped cross section, and has an annular groove 216 in plan view. Distribution tray 212 is rotated at a constant speed by motor 219.
The scraping device 215 has a disk 217 that moves up and down and rotates, and a scraping plate 218 is provided on the disk 217.

  As shown in FIG. 49, the medicine packaging device 203 includes a packaging hopper 220 and a packaging device 221.

Next, the procedure in the case of packaging powder using the powder packaging apparatus 200 will be described.
The operation of packaging the powder is performed by the pharmacist operating the powder packaging device 200 in accordance with a doctor's prescription. That is, the pharmacist confirms the doctor's prescription and takes out the medicine bottle containing the prescribed powder from a medicine shelf (not shown). Then, the total weight of the specific powder prescribed using a balance such as a balance is measured.
That is, if it is a powder taken three times a day and is prescribed 1.0 gram per dose, and 20 days of medication is prescribed, (1.0 × 3 × 20 = 60) grams Of powder is taken out. More specifically, a container is placed on a scale, tared, and a powdered spoon is used to take out the powder from the medicine bottle, put the powder in a container on the scale, and weigh 60 grams of powder.

Then, the weighed 60 grams of powdered medicine is put into the feeding hopper 205 of the medicine 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 further the distribution tray 212 is rotated at about 20 to 30 revolutions per minute.
The powder charged in 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. As the trough 210 vibrates, the powder slowly moves to the tip side and is rectified. Further, the rectification progresses while moving on the trough 210, and the flow of the medicine becomes a laminar flow state. That is, the distribution of the drug in a cross section perpendicular 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 toward the tip side at a constant rate per hour.
Finally, the powder that moves at the top reaches the tip of the trough 210, and the powder that moves at the top falls from the tip of the trough 210 into the groove 216 of the distribution tray 212. Further, the powder that follows will fall to the distribution tray 212 by a certain amount per hour. Finally, the last powder falls into the distribution tray 212 and all 60 grams of powder enters the groove 216.

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

  When the powder falls on the distribution tray 212, the rotation of the distribution tray 212 is once stopped. Thereafter, the disk 217 of the scraping device 215 is dropped into the groove 216 of the distribution tray 212. Thereafter, the distribution tray 212 is rotated by an angle corresponding to the number of distribution. In the above example, 60 grams of powder is divided into 60 packets, so the distribution tray 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 tray 212 by the scraper 218 and put into the packaging hopper 220. The powder falling from the packaging hopper 220 is packaged by the packaging device 221.

JP 2000-85703 A

By using the powder medicine packaging device 200 disclosed in Patent Document 1, it is possible to automate most of the work for packaging powder medicines one by one.
However, it is hard to say that the powder medicine packaging device 200 of the prior art is a device that can completely automate the powder medicine packaging because it still has to rely on human hands.
That is, in the prior art powder packaging apparatus 200, it is essential for the pharmacist to take out a medicine bottle containing a desired powder from a medicine shelf and to measure a predetermined amount of powder from the medicine bottle.

  Therefore, the present invention aims to develop a medicine feeder that can automate the work of weighing out powdered medicines by paying attention to the above-mentioned problems of the prior art.

  An aspect for solving the above-described problem is a medicine feeder including a medicine container and a main body device, wherein the medicine container is detachable from the main body device, and the medicine container is discharged. The main body device directly or indirectly determines the weight of the drug container, the vibration table, the vibration means for vibrating the vibration table, the container holding means for temporarily fixing the drug container to the vibration table, Weight measuring means to measure automatically, place the medicine container on the shaking table, fix the medicine container to the shaking table with the container holding means, vibrate the shaking table and discharge the medicine little by little from the medicine discharging part The drug feeder is capable of detecting the discharge amount of the drug by the weight measuring means.

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

  The medicine feeder is desirably provided with a plurality of contact sensors for detecting whether or not the medicine container is in contact with the vibration table.

In the medicine feeder of this mode, since a plurality of contact sensors for detecting whether or not the medicine container is in contact with the vibration table are provided, the posture of the medicine container with respect to the vibration table can be confirmed. Therefore, the medicine feeder of the present invention can keep the variation of the posture of the medicine container with respect to the vibration table within a certain range.
In other words, the drug feeder of this embodiment is configured to move the drug by vibrating the drug container by bringing the drug container into direct contact with the vibration table and vibrating the vibration table. Must be within range.
For example, in order to discharge a fixed amount of medicine per unit time from the medicine container by vibration, it is desirable that the medicine container is in a horizontal posture. Assuming that the medicine container is attached to the shaking table in a posture in which the medicine discharge section side of the medicine container is inclined upward, the medicine is difficult to move to the medicine discharge section side even if vibration is applied.
Also, if the axis of the drug container and the center line of the shaking table are misaligned or crossed, the drug will not be in a laminar flow state when the drug is moved by vibration, and turbulent flow will occur. It becomes a state. That is, the direction in which the shaking table attempts to move the drug differs from the direction of the flow path of powder or the like regulated by the peripheral wall of the drug container, and the distribution of the drug in the cross section intersecting the flow direction varies.
On the other hand, in this aspect, since the variation of the posture of the medicine container with respect to the shaking table can be kept within a certain range, the medicine distribution in the cross section intersecting with the flow direction becomes uniform. Therefore, according to the present invention, the movement of the drug is easily rectified, and a laminar flow state is likely to occur. Therefore, according to the medicine feeder of this aspect, the variation in the discharge amount per unit time is small.

As for a medicine feeder, it is desirable that a part or all of a medicine container is a magnetic substance, and a container holding means has a magnet.
The magnet is preferably an electromagnet.

Therefore, in the medicine feeder of the present invention, the adhesion between the shaking table and the medicine container is high, and the vibration of the shaking table can be accurately transmitted to the medicine container.

  Part or all of the drug container is a magnetic material, and the container holding means has a permanent magnet and an electromagnet. At least the drug container is fixed to the vibration 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 with respect to the shaking table by generating a magnetic force that cancels out the.

  In the medicine feeder of this aspect, the container holding means has a permanent magnet and an electromagnet, and the medicine container is fixed to the vibrating table by at least the magnetic force of the permanent magnet. For this reason, in a state in which the medicine container is mounted on the main body device, the amount of electricity applied to the electromagnet is small. If a configuration in which the drug container is fixed to the vibration table only by the magnetic force of the permanent magnet is employed, it is not necessary to energize the electromagnet while the drug container is fixed to the vibration table. Therefore, the electromagnet does not generate heat and the medicine in the medicine container is not heated. Further, since it is not necessary to energize the electromagnet while the medicine container is fixed to the shaking table, the power consumption is small. For this reason, even the entire medicine feeder consumes less power and generates less heat, so it is difficult to affect the medicine.

  The medicine feeder preferably includes a cooling means for cooling the main body device.

  The medicine feeder has an anti-vibration table, and there is an anti-vibration member between the vibrating means and the anti-vibration table, and the weight measuring means detects the total weight of the anti-vibration table, and the weight measuring means It is desirable to detect the discharge amount of the medicine based on the change in the detected weight.

In the medicine feeder of this aspect, the weight measuring means detects the total weight of the vibration isolator. The vibration table is vibrated by the vibration means, but since the vibration isolation member is provided between the vibration means and the vibration isolation table, the vibration of the vibration means is not easily transmitted to the vibration isolation table.
In the medicine feeder of this aspect, the total weight of the vibration isolator is detected by the weight measuring means as described above, so that the weight measuring means is hardly affected by vibration and can accurately measure the weight of the medicine container and the like. .

The rectifying member 7 is a comb-like plate (the comb shape is not shown in FIGS. 1, 2 and 3). The flow regulating member 7 is inside the container body 5, and a gap (narrowed opening 13) is formed only between the peripheral wall lower surface 12 side. The flow regulating member 7 is 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.
The flow regulating member 7 can be attached to and detached from the container body 5. The illustrated rectifying member 7 is merely an example, and can be replaced according to the properties of the medicine.

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

Next, the main unit 3 will be described.
As shown in FIGS. 1 to 3, the main unit 3 includes a vibration table 20, vibration means 21 a and 21 b, an intermediate base 22, a vibration isolation table 23, a weight measurement means 25, and a base member 26 from the top.

Hereinafter, description will be made sequentially. The vibration table 20 is a block-shaped mounting table, in which electromagnets 30a and 30b are built. That is, the vibration table 20 is provided with magnet mounting holes 28a and 28b, and electromagnets 30a and 30b are built in the magnet mounting holes 28a and 28b.
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 30 a and 30 b have a slight degree of freedom with respect to the vibration table 20.
The attracting portions (tips of iron cores) 31a and 31b of the electromagnets 30a and 30b are at a position lower than the upper surface of the vibration table 20, as shown in FIG.
Contact sensors 33a, b, c, and d are provided at the four corners of the vibration 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 vibration table 20.

The vibration means 21a and 21b are piezoelectric elements and have a plate shape.
The intermediate table 22 and the vibration isolation table 23 actually have complicated shapes as will be described later, but are mechanically only a table, and in FIGS. Yes.
The weight measuring means 25 is a known load cell, has an upper installation surface 36 and a lower installation surface 37, and is in a position where both are offset.
The base member 26 also has a complicated shape as will be described later, but is mechanically only a base, and is simply illustrated as a flat plate in FIGS. 1 to 3.

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

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

Further, a weight measuring means 25 is arranged at the lower part of the vibration isolator 23, and a base member 26 is arranged at the lower part thereof.
In the weight measuring means 25, the upper installation surface 36 is connected to the lower surface of the vibration isolation table 23, and the lower installation surface 37 of the weight measurement 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 offset, the intermediate portion of the weight measuring means 25 has a structure that is cantilevered with respect to the base member 26. The vibration isolator 23 is supported on the free end side.
In the present embodiment, there is no member other than the weight measuring means 25 described above that connects the vibration isolator 23 and the base member 26. Therefore, the vibration isolator 23 has a structure that is supported by the weight measuring means 25 so as to be hollow from the vibration isolator 23.

The base member 26 is attached to the vicinity of the distribution tray 212 of the powder distribution device 202 via the vibration isolation member 41.
Since the base member 26 is a base that supports the entire main body device 3 of the medicine feeder 1, the main body device 3 is attached in the vicinity of the distribution tray 212 of the powder distribution device 202.

  In the medicine feeder 1 of the present embodiment, as described above, the vibration table 20 is supported hollow by the vibration means 21a and 21b. Therefore, when the vibration means 21a and 21b are vibrated, The vibration is transmitted to the vibration table 20, and the vibration table 20 vibrates.

  In this embodiment, the vibration table 20, the vibration means 21 a and 21 b, the intermediate table 22, and their accessories are all supported by the vibration isolation 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, the weight of the upper member 36 on the weight measuring unit 25 is higher than that of the weight measuring unit 25 in terms of the mechanism. Accordingly, the weight measuring unit 25 measures all the weights of the members above the weight measuring unit 25. Therefore, in this embodiment, when the medicine container 2 is placed on the vibration table 20, the weight of the medicine container 2 is indirectly measured.

As described above, the vibration table 20 and the vibration means 21a and 21b generate vibrations, but all the members that generate vibration are mounted on the intermediate table 22, and the intermediate table 22 and the vibration isolation table. Since the vibration isolating member 40 is interposed between the vibration isolation table 23 and the vibration isolation table 23, the vibrations of the vibration table 20 and the excitation means 21 a and 21 b are not easily transmitted to the vibration isolation table 23.
In the present embodiment, since the weight measuring means 25 is connected to the vibration isolation table 23, the weight measurement means 25 is not easily affected by vibrations of the vibration table 20 and the vibration excitation means 21a and 21b, and is accurate in weight. Can be detected.
That is, in the present embodiment, since the vibration isolating member 40 is between the vibration exciting means 21a, 21b and the vibration isolating base 23, the weight measuring means 25 is hardly affected by vibration.
Furthermore, the present embodiment further includes an intermediate base 22 and a vibration isolation base 23 that supports the intermediate base 22 via a vibration isolation member 40, and the vibration means 21 a and 21 b and the vibration base 20 are placed on the intermediate base 22. Therefore, the weight measuring means 25 is not easily affected by vibration.

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

The medicine feeder 1 according to the present embodiment constitutes a part of the powder medicine packaging device (or the whole shape of the medicine dispensing device is not shown) as described above. As shown in FIG. It is installed in the vicinity of the distribution tray 212. As a device constituting the powder medicine packaging device, there is a robot (container moving means) 43 for transporting the medicine container 2. The robot 43 has an XY table (not shown) and a hand 45 that holds the medicine container 2.
Moreover, the powder medicine packaging device (the whole 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 that reads the drug name, prescription amount, and other contents of the prescription drug described in the prescription.

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

The electromagnets 30a and 30b built in the vibration table 20 are energized. As a result, 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 adsorption portions (tips of iron cores) 31a and 31b on the vibration table 20 side.
In this embodiment, the electromagnets 30 a and 30 b are fixed to the bottoms of the magnet mounting holes 28 a and 28 b via the elastic bodies 32 a and 32 b, and the electromagnets 30 a and 30 b have a slight degree of freedom with respect to the vibration table 20. 2, the electromagnets 30 a and 30 b slightly move toward the iron plate portion 6, and the adsorbing portions 31 a and 31 b are in close contact with the iron plate portion 6 of the medicine container 2.
Furthermore, due to the elasticity of the iron plate part 6 of the medicine container 2 and the vibration table 20 itself, these are slightly deformed and become familiar.
As a result, the iron plate part 6 of the medicine container 2 is in close contact with the surface of the vibration table 20 and the electromagnets 30a and 30b.

Subsequently, in the present embodiment, the close contact degree between the medicine container 2 and the vibration table 20 and the posture of the medicine container 2 are confirmed.
Specifically, if electricity is applied between the contact sensors 33a, b, c, d provided around the electromagnets 30a, 30b and there is conduction between the contact sensors 33a, b, c, d, the drug container 2 and It is determined that the degree of adhesion of the vibration table 20 and the posture of the medicine container 2 are normal. Conversely, if there is no conduction between the contact sensors 33a, b, c, d, the degree of contact between the medicine container 2 and the vibration table 20 is insufficient, or the posture of the medicine container 2 is abnormal.

That is, the contact sensors 33 a, b, c, d are electrodes exposed on the surface of the vibration table 20. On the other hand, since the iron plate portion 6 is provided on the outer peripheral portion of the drug container 2 and on the lower surface 12 of the peripheral wall, the drug container 2 is in close contact with the vibration 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 part 6, and the contact sensors 33a, b, c, d are conducted through the iron plate part 6.
On the contrary, if there is a problem such as insufficient adhesion between the medicine container 2 and the vibration table 20, any or all of the contact sensors 33a, b, c, d do not contact the iron plate part 6, and the contact sensor. 33a, b, c, d are insulated from each other.

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

Further, the weight of the drug container 2 is measured before and after the start of vibration. The weight of the medicine container 2 is obtained by subtracting a certain value from the weight detected by the weight measuring means 25. More specifically, the weight of the medicine 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, the weight measuring means 25 is such that the weight of the vibration table 20, the vibration means 21 a and 21 b, the intermediate table 22 and its accessories are all supported by the vibration isolation table 23. Since the weight is measured, the weight measuring means 25 measures all the weights of the members above the weight measuring means 25.
Therefore, in a state where the medicine container 2 is placed on the vibration table 20, a value obtained by adding the weight of the medicine container 2 to the weight of the vibration table 20 or the like is detected by the weight measuring unit 25.
Here, since the weight of the vibration table 20 or the like is known, the weight of the medicine container 2 can be indirectly detected by subtracting the weight of the vibration table 20 or the like from the weight detected by the weight measuring means 25.
The weight of the drug container 2 immediately after installation on the vibration table 20 is stored as the original weight G. The weight of the medicine container 2 is constantly monitored. That is, the current weight of the medicine container 2 is monitored as the current weight g.

When the vibration table 20 starts to vibrate, the medicine container 2 vibrates. Here, in the present embodiment, the drug container 2 is firmly joined to the vibration table 20 by the electromagnets 30a and 30b, and the degree of close contact with the vibration table 20 is high. Vibrates at the same frequency. As a result, the powder stored in the powder storage part 17 of the medicine container 2 moves slowly toward the medicine discharge part 8 side.
Note that, when the vibration table 20 vibrates, the drug container 2 itself also receives a force that moves in the forward direction. However, in this embodiment, a protrusion 16 is provided at the rear end of the drug container 2. Is in contact with a part of the vibration table 20 or the like, so that the medicine container 2 itself is prevented from moving forward. Therefore, the medicine container 2 does not move, and only the powder in it moves.

The powder reaches the constriction opening 13 formed by the site of the flow regulating member 7. Since the opening height of the stenosis opening 13 is limited, the height of the powder medicine passing through the stenosis opening 13 is adjusted. That is, the powder flows on the peripheral wall lower surface 12 of the drug container 2 as if it were a river, but the height from the peripheral wall lower surface 12 to the upper part of the powder is aligned in the width direction.
The powder that has passed through the narrowed opening 13 is discharged to the outlet path 18. The powder then flows through the outlet channel 18 like a river, finally reaches the medicine discharge part 8 of the medicine container 2, falls like a waterfall, and enters the groove 216 of the lower distribution tray 212.

  That the powder is falling is confirmed by a decrease in the weight of the drug container 2. That is, in the present embodiment, even when powder is falling from the drug discharge unit 8 of the drug container 2, the current weight of the drug container 2 is continuously monitored as the current weight g. And the original weight G of the chemical | medical agent container 2 immediately after installation in the shaking table 20 is compared with the present weight g, and the fall amount H (G minus g) of a powder is always calculated.

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

  After that, like the powder packaging device of the prior art, the rotation of the distribution tray 212 is stopped, the distribution tray 212 is rotated by an angle corresponding to the number of distribution, and the powder is put out of the distribution tray 212 by a scraping device (not shown). Scrap out and send to the drug packaging device (not shown) on the rear side.

  Next, an embodiment of the present invention that is closer to practical design will be described. In order to reduce the overall height of the medicine feeder 50 described below, the member shape is greatly different from the mechanism diagram shown in FIG. The function is the same as in the previous embodiment. The constituent members of the medicine feeder 50 described below basically have all the functions of the medicine feeder 1 described above. for that reason. Although the shapes are different, members having the same function are given the same numbers and names. In addition, the description of the members and the like will be described with a focus on the parts different from the previous embodiment, and the overlapping parts will be briefly described.

The drug feeder 50 having a shape close to practical design is configured by the drug container 2 and the main body device 3 as in the previous embodiment (FIG. 4).
First, the structure of the medicine container 2 will be described. In the present embodiment, five types of drug containers 2A, 2B, 2C, 2D, 2E, and 2F are prepared according to applications.
That is, the medicine container 2A of the first form is a type in which the medicine discharge part 8 does not have a lid as shown in FIG. The medicine container 2B of the second form is a two-sided open type as shown in FIG. 10, and a part corresponding to the top surface is greatly opened when the medicine discharge part 8 has no lid and is in a horizontal posture. is there. The drug container 2C of the third form is a sealed type as shown in FIG. 12, and has a lid. The drug container 2D of the fourth form is a sealed type as shown in FIG. 34, and has a lid. The medicine container 2E of the fifth form is a sealed 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.

If it demonstrates one by one, the chemical | medical agent container 2A of 1st form will be comprised by the container main body 5, the iron plate part 6, and the rectification | straightening member 7 like FIG. 5, FIG.
The container body 5 is a vertically long container made of resin, and one end in the longitudinal direction serves as a medicine discharge portion 8.
In the present embodiment, the cross-sectional shape of the container body 5 is a hexagon as shown in FIGS. That is, there are six peripheral wall surfaces 11 of the container body 5 including the peripheral wall lower surface 12.
More specifically, the cross-sectional shape of the container body 5 is symmetric with respect to the state in which the container body 5 is placed horizontally as shown in FIGS. 5 and 6, there is a peripheral wall upper surface 51 that faces the peripheral wall lower surface 12 with reference to a state in which the container body 5 is horizontally placed.
The surfaces connecting the peripheral wall upper surface 51 and the peripheral wall lower surface 12 include left and right vertical peripheral walls 52a and 52b and left and right inclined peripheral walls 53a and 53b.
Therefore, when the horizontal placement state as shown in FIG. 5 and FIG. 6 is used as a reference, the container body 5 is clockwise from the top, the peripheral wall upper surface 51 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 peripheral wall lower surface 12 in a horizontal posture, a left inclined peripheral wall 53a in an inclined posture, and a left vertical peripheral wall 52a in a vertical posture.
Therefore, in this embodiment, the peripheral wall lower surface 12 through which powder flows is smaller than other surfaces. Moreover, in this embodiment, it has a structure in which powder medicine is easy to gather on the surrounding wall lower surface 12 from another surrounding wall.
Also in the present embodiment, the protrusion 16 is provided on the outer peripheral surface side of the container body 5. The positions of the protrusions 16 are the same as in the previous embodiment, and protrude downward when the container body 5 is in a horizontal position.

The iron plate portion 6 is formed in a shape that matches the peripheral wall lower surface 12 and a part of the left and right inclined peripheral walls 53a, 53b.
That is, as shown in FIG. 6, the cross-sectional shape of the iron plate part 6 is a right and left object, and has a flat peripheral wall lower surface contact part 55, and inclined peripheral wall contact parts 56a and 56b 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, 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, b. Is equal to the angle.
The iron plate portion 6 is bonded to a portion corresponding to the peripheral wall lower surface 12 on the outer peripheral surface side of the container body 5.

As shown in FIG. 8, the rectifying member 7 is formed of 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-like portion 58 extends obliquely from the vicinity of the lower side of the closing plate portion 57, and the free end side is divided into a plurality of shapes to form a comb shape.
The second comb-shaped portion 60 extends obliquely rearward from the back surface of the closing plate portion 57, and the free end side is divided into a plurality of shapes to form a comb shape.

The flow regulating member 7 is inside the container body 5 as shown in FIGS. 5 and 7, and the free ends of the comb-shaped portions 58 and 60 are 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 back side of the container body 5.
As shown in FIG. 7, a narrowed opening 13 is formed between the free end of the first comb-shaped portion 58 and the peripheral wall lower surface 12 and between the free end of the second comb-shaped portion 60 and the peripheral wall lower surface 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 back side (bottom surface 10) 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 functions as the powder storage part 17 with the rectifying member 7 as a boundary. Further, the region of the medicine discharge portion 8 functions as the lead-out passage portion 18 with the rectifying member 7 on the peripheral wall lower surface 12 as a boundary.

Next, a modified example of the medicine container 2 will be described. In the description of each modified example described below, B, C, D, E, and F are added to the same numbers for members that are common to the drug container 2A described above and parts that perform common functions. Therefore, detailed description is omitted.
The 2nd form chemical | medical agent container 2B is demonstrated referring FIG. 9, FIG. As shown in FIG. 10, the medicine container 2B is a two-sided open type in which the portion corresponding to the top surface is greatly opened when the medicine discharging unit 8 is not covered and is in a horizontal posture. That is, it can be said that the medicine container 2B is obtained by removing the upper side of the medicine container 2A of the first form described above. More simply, in the medicine container 2B, a portion corresponding to the peripheral wall upper surface 51 (FIG. 6) is missing.
The medicine container 2B is configured by a container body 5B, an iron plate portion 6B, and a rectifying member 7B, similarly to the medicine container 2A of the first form described above.
The container body 5B is a vertically long and bowl-shaped container made of resin, and one end in the longitudinal direction is a medicine discharge part 8B.
In the present embodiment, there are five peripheral wall surfaces 11B of the container body 5B including the peripheral wall lower surface 12B.
More specifically, the cross-sectional shape of the container body 5B is symmetric with respect to the state where the container body 5B is horizontally placed as shown in FIG. 9 and FIG. 10, the side facing the peripheral wall lower surface 12B is opened with reference to the state where the container body 5B is horizontally placed.
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 is the same as that of the previous embodiment, and protrudes downward when the container body 5B is in a horizontal posture.

The iron plate portion 6B has the same shape as the iron plate portion 6 of the medicine container 2A of the first form 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 bonded to a portion corresponding to the peripheral wall lower surface 12B on the outer peripheral surface side of the container body 5B.

  The main part of the rectifying member 7B is the same as that adopted in the medicine container 2A of the first form described above, and the closing plate part 57B, the first comb-like part 58B and the second comb-like part (second comb) The shape portion is not shown in the drawing). However, the overall height of the closing plate portion 57B is lower than that employed in the first-form drug container 2A.

Next, a medicine container 2C according to a third embodiment will be described with reference to FIG. The medicine container 2C is a sealed type, and a lid member 120 is provided on the container body 5C.
That is, the medicine container 2 </ b> C includes a container body 5 </ b> C, an iron plate part 6 </ b> C, and a lid member 120. Further, in the medicine 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 functions in the same manner as the rectifying members 7A and 7B described above, but is described 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 transporting iron plate portion 157.
The container body 5C is a vertically long container made of a resin, and one end in the longitudinal direction is a medicine discharge part 8C. In the present embodiment, the cross-sectional shape of the container body 5C is a hexagon as shown in FIGS. That is, there are six circumferential wall surfaces 11C of the container body 5C including the circumferential wall lower surface 12C.
More specifically, the cross-sectional shape of the container main body 5C is symmetrical with respect to the state in which the container main body 5C is horizontally placed as shown in FIG. And there exists the surrounding wall upper surface 51C which opposes the surrounding wall lower surface 12C on the basis of the state which mounted the container main body 5C horizontally like FIG.
The surfaces connecting the peripheral wall upper surface 51C and the peripheral wall lower surface 12C include left and right vertical peripheral walls 52aC and 52bC, and left and right inclined peripheral walls 53aC and 53bC.

  Accordingly, when the horizontal placement state as shown in FIG. 11 is used as a reference, the container body 5C is rotated clockwise from the top as shown in FIG. 13 in the horizontal posture upper surface 51C, the vertical right right peripheral wall 52bC, and the inclined posture. The right inclined peripheral wall 53bC, the horizontal peripheral lower surface 12C, the inclined left inclined peripheral wall 53aC, and the vertical left peripheral peripheral wall 52aC are surrounded by a total of six surfaces.

However, in this embodiment, the peripheral wall lower surface 12C is not a flat surface, but has a stepped portion 121 on the side of the medicine discharge portion 8 as shown in FIGS. That is, the medicine discharge part 8C side is lowered to the lower side with respect to the horizontal posture to form the lower part 122. In other words, 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.
Therefore, each wall connected to the peripheral wall lower surface 12C, that is, the right inclined peripheral wall 53bC in the inclined posture and the left inclined peripheral wall 53aC in the inclined posture and connected to the lower step portion 122 has a larger area than the other portions.
In the present embodiment, since the lower step portion 122 is provided in the portion of the peripheral wall lower surface 12C on the drug discharge portion 8C side, the container discharge portion 8C side of the container body 5C swells downward.

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

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 two pressing blocks 93a and 93b, and a screw 99a is inserted between them. Excitation means 21a, 21b and connection plates 91a, 91b are fixed.
Further, connecting plates 91a and 91b are in contact with the inclined surfaces 67a and b of the vibration table 20, and are attached to the inclined surfaces 67a and b of the vibration table 20 by a holding block 93c and screws 99b.

  On the other hand, on the lower side of the vibration means 21a and 21b, the connecting piece 72b is brought into contact with the inclined surfaces 78a and b of the intermediate table 22, and is attached to the inclined surfaces 78a and b of the intermediate table 22 by the holding block 93d and screws 99c. It has been.

  In the present embodiment, vibration means 21 a and 21 b exist between the vibration table 20 and the intermediate table 22, and the vibration table 20 is not supported at portions other than the vibration means 21 a and 21 b. Therefore, the vibration table 20 has a structure that is supported hollowly from the intermediate table 22 by the vibration means 21a and 21b.

  In addition, an anti-vibration table 23 is disposed below the intermediate table 22. Explaining the positional relationship between the two, as shown in FIGS. 22, 23, and 24, the ridge 80 provided at the center of the vibration isolation table 23 enters the cavity 75 of the intermediate table 22. However, the top surface 81 of the ridge 80 is not in contact with the inner surface of the hollow portion 75 of the intermediate table 22. That is, although the intermediate table 22 and the vibration isolation table 23 are complicated, 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 support portions 83a, 83b, 83c, and 83d of the vibration isolator 23 immediately below the four projecting portions 77a, b, c, and d of the intermediate stand 22, and the two are connected by a vibration isolating member 40. ing.
The anti-vibration member 40 is a member having both an anti-vibration function and a vibration suppression function, and is a combination of a spring 38 and a vibration suppression rubber 96 as shown in the figure.
That is, the four projecting portions 77a, b, c, and d of the intermediate base 22 are provided with round holes 85 that open downward as shown in FIG. It enters the round hole 85.
In the present embodiment, there is no member other than the above-described anti-vibration member 40 for connecting the intermediate base 22 and the anti-vibration base 23. Therefore, the intermediate stand 22 has a structure that is supported hollowly from the vibration isolation table 23 by the vibration isolation member 40.
As described above, although the intermediate stand 22 and the vibration isolator 23 are complicated, they are mechanically the same as the structure shown in FIG. 1, and the intermediate stand 22 is made hollow from the anti-vibration stand 23 by the anti-vibration member 40. It has a supported structure.

Further, as shown in FIGS. 22, 23, and 24, a weight measuring means 25 is arranged at the lower part of the vibration isolator 23, and a base member 26 is arranged at the lower part thereof.
Most of the weight measuring means 25 is in a ridge 80 provided at the center of the vibration isolator 23 as shown in FIGS. 22, 24 and 25, and the upper installation surface 36 of the weight measuring means 25 is anti-vibrated. 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 base member 26.
As described above, since the upper installation surface 36 and the lower installation surface 37 are offset, the intermediate portion of the weight measuring means 25 has a structure that is cantilevered with respect to the base member 26. The vibration isolator 23 is supported on the free end side.
In the present embodiment, most of the weight measuring means 25 enters the inside of the vibration isolation table 23 and the intermediate table 22 and has a complicated positional relationship, but is 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 base member 26, and supports the vibration isolator 23 on the free end side.

In the present embodiment, there is no member other than the weight measuring means 25 described above that connects the vibration isolator 23 and the base member 26. Therefore, the vibration isolator 23 has a structure in which the weight measuring means 25 is supported hollow from the base member 26.
In the present embodiment, most of the weight measuring means 25 is located in the ridge 80 provided at the center of the vibration isolator 23 as shown in FIGS. Since the ridges 80 provided in are located in the hollow portion 75 of the intermediate table 22, it can be said that most of the weight measuring means 25 has entered the intermediate table 22 in terms of the height direction.
Therefore, in this embodiment, the influence of the height of the weight measuring unit 25 on the overall height of the main body device 3 is small, and the overall height of the main body device 3 is low.

Moreover, the base member 26 is attached to the vicinity of the distribution tray 212 of the powder distribution apparatus 202 via the vibration isolating member 41 similarly to the previous embodiment.
That is, the four corner portions of the base member 26 are cut and raised to form spring support portions 90a, b, c, d (FIG. 19). The lower surfaces of the spring support portions 90a, b, c, d and the powdered medicine A base or the like of the packaging device 202 is attached via a vibration isolation member 41. The vibration isolating member 41 includes a spring 84 (FIG. 20) and a vibration isolating rubber (not shown).

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

That is, also in this embodiment, the medicine container 2C is transported by a robot hand (not shown) or the like.
When the medicine container 2C is transported, the medicine container 2C is changed in posture from the initial vertical posture to the horizontal posture as shown in FIG. 11 and FIG.
At this time, although the posture of the hand 45 is controlled by the robot 43 in FIG. 1 so that the axis BC of the medicine container 2C and the axis MC of the main body device 3 are matched as much as possible, it is difficult to always match them completely. In some cases, as shown in FIG.

The drug container 2C is installed on the vibration 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 shifted, but in this embodiment, an iron plate provided near the bottom of the drug container 2C. The portion 6C has inclined peripheral wall abutting portions 56a and 56b, which are substantially tapered.
On the other hand, the vibration table 20 is also provided with the edge 66 on the mounting surface 61 as described above, and has a substantially tapered shape.
Therefore, when the medicine container 2C is installed on the shaking table 20, it is guided by the taper, and the inclined peripheral wall contact portions 56a and 56b on the medicine container 2C side and the inclined surface 68 of the shaking table 20 coincide with each other as shown in FIG. Tend to.

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

  Therefore, the posture of the medicine container 2C is corrected, and the axis BC of the medicine container 2C and the axis MC of the main body device 3 approach each other as shown in FIG. However, the inclined peripheral wall contact portions 56a and 56b of the medicine container 2C and the inclined surface 68 of the vibration table 20 do not completely coincide with each other, and as shown in FIG. There may be a portion D where b and the inclined surface 68 of the vibration table 20 do not coincide with each other. In this case, as shown in FIG. 27B, the axis BC of the medicine container 2C and the axis MC of the main body device 3 are slightly shifted.

  When the electromagnets 30a and 30b are energized in this state, the planar peripheral wall lower surface contact portion 55C provided on the peripheral wall lower surface 12C of the medicine container 2C is attracted to the electromagnets 30a and b, and the peripheral wall lower surface contact portion 55C vibrates. The peripheral wall lower surface contact portion 55 </ b> C is brought into close contact with the mounting surface 61 of the vibration table 20 by being drawn toward the table 20 side. Then, the taper shapes of the medicine container 2C and the vibration table 20 are matched by the force received at that time, and the axis BC of the medicine container 2C and the axis MC of the main body device 3 are matched as shown in FIG.

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

  In the present embodiment, the contact degree between the medicine container 2C and the vibration table 20 and the posture of the medicine container 2C are set on condition that the contact sensors 33a, b, c, d provided at the four corners of the placement surface 61 are electrically connected to each other. Is determined to be normal.

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

  In the present embodiment, when the medicine in the medicine container 2C advances toward the medicine discharge portion 8C, the medicine passes through the comb-shaped portion 142 of the inclined plate portion 141 shown in FIG. It passes through the gap of the wire across the rectifying coil 126. Therefore, the drug flow is smoothed. Even if a lump of medicine is present, the lump collapses when passing through the comb-shaped portion 142 and the rectifying coil 126, and returns to a powder form.

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

Furthermore, when 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 chemicals move together and reach the position of the comb-like rectifying member 130D, the upper side of the two layers is scraped up by a plate-like portion 362 of the comb-like rectifying member 130D as shown in FIG. It is done. In particular, since the comb-like rectifying member 130D is generally inclined, the upper side of the two layers is raised at the plate-like portion 362 of the comb-like rectifying member 130D, and is further returned to the bottom surface 10D side as indicated by an arrow. . Therefore, the old drug layer 360 moving on the lower layer side is preferentially discharged, and a first-in first-out flow of the drug in the drug container 2D can be realized.

Next, peripheral devices of the medicine feeder 50 will be described.
The medicine feeder 50 according to the present embodiment constitutes a part of the medicine dispensing apparatus 100 having a powder packaging function.
The overall structure of the medicine dispensing apparatus 100 is as shown in FIG. 30, for example. The medicine dispensing apparatus 100 is functionally divided into a medicine shelf area 103, a medicine division area 105, and a medicine packaging area 106 in the vertical direction.
In the uppermost drug shelf area 103, drug container storage shelves 101 are arranged in the periphery, and a drug container moving device 102 is provided therein.
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 region 103, and dust in the medicine shelf region 103 is removed. For example, a blowing fan is provided in the medicine shelf region 103, and the air in the medicine shelf region 103 is circulated by the blowing fan. A filter is provided in a fixed ventilation path such as the intake side of the blower fan to remove dust floating in the medicine shelf region 103.

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

In the medicine division area 105, a powder distribution device 202 is provided. In this embodiment, the powder distribution device 202 has two distribution trays 212. A plurality of drug feeders 50 according to the present embodiment are installed in the powder distribution device 202. In the present embodiment, a plurality of medicine feeders 50 are installed on each distribution tray 212. More specifically, three medicine feeders 50 are installed on each distribution tray 212. Each medicine feeder 50 is attached to each distribution tray 212 in a tangential direction. The angle at which the medicine feeder 50 is attached to each distribution tray 212 is not limited to the tangential direction. However, by attaching the medicine feeder 50 to each distribution tray 212 in the tangential direction, the medicine distribution accuracy is improved. There is an increasing 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 vibration table 20, or when the medicine container 2C is removed from the vibration table 20, there is little useless operation of the medicine container moving device 102. The effect of becoming can be expected.
A medicine packaging device 203 is built in the medicine packaging area 106.
The medicine dispensing apparatus 100 includes a prescription reading unit 46 that reads a prescription and a control device 47 that controls the operation of each device.

Further, on the outer wall side of the medicine packaging region 106, a medicine container inlet 151 as shown in FIG. 29 is provided. Inside the medicine container inlet 151, 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 medicine container 2 </ b> C is set in the medicine container inlet 151, the total weight of the medicine container 2 </ b> C is measured and stored in the memory of the control device 47. Further, a barcode or the like (not shown) provided on the medicine container 2C is read by a barcode reader or the like, and the medicine container 2C is transported to a predetermined position in the medicine shelf region 103 by the medicine container moving device 102 and stored.
Here, in this embodiment, the medicine container moving device 102 has the hand portion 112 of the electromagnet 170. In this embodiment, as shown in FIG. 31, the electromagnet 170 is brought close to the transporting iron plate part 157 of the drug container 2C, and then the electromagnet 170 is energized to attract the transporting iron plate part 157 and hold the drug container 2C. Move.

  It should be noted that, as a second type of medicine container 2B (FIG. 9), it is a two-sided open type container that has no lid and has a position that corresponds to the top surface when opened in a horizontal position. When the container 2B is used, a medicine container that has been weighed separately on a dispensing table or the like or that has not been weighed is introduced from the opened upper side of the medicine container 2B (upper side when the medicine container 2B is placed in a horizontal position). Set in the inlet 151. When the second type medicine container 2B is set, the total weight of the medicine container 2B is measured, stored in the memory of the control device 47, and then directly conveyed to any medicine feeder 50 by the medicine container moving device 102. Then, an amount of medicine based on the prescription information is dispensed to the powder distribution device 202.

The overall control of the medicine dispensing apparatus 100 is generally as shown in the flowchart of FIG.
Hereinafter, the overall operation of the medicine dispensing apparatus 100 will be described with reference to the flowchart of FIG.

In the present embodiment, as shown in FIG. 32, all the operations are started when the prescription reading means 46 reads the contents of the prescription.
That is, when the contents of the prescription are input in Step 1, the process proceeds to Step 2, and the work for carrying out the medicine container 2C is started immediately. More specifically, the drug container moving device 102 is driven, and the drug container 2 containing the drug that matches the prescription is selected from the many 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 knob 147 of the movable lid 134 is pressed by a pressing piece (not shown) to open the movable lid 134, and the movable lid 134 is opened by the attractive force of the magnet 156 for maintaining the open state. Maintained.

Then, the process proceeds to step 3, and the electromagnets 30 a and 30 b are energized to fix the medicine container 2 </ b> C to the vibration table 20.
Thereafter, the process proceeds to step 4 to start the timer. This timer defines a time for determining whether or not the medicine container 2C has been normally installed, and is, for example, a very short one of about 1 second.
If all of the contact sensors 33a, b, c, d are energized before the timer finishes timing (YES in step 5), it is determined that the medicine container 2C is installed in a normal posture, and step Move to 6. On the other hand, if the contact sensors 33a, b, c, d cannot confirm contact even after waiting for a certain time (step 12), there is a high possibility that there is an abnormality such as a foreign object on the vibration table 20. Then, the process proceeds to step 13 where a series of operations is 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 gripped and lifted by the hand unit 112, and the drug container 2C is again held in the main body device 3 of the drug feeder 50. The operation after step 3 is retried.

  In the first trial or another trial, the energization in step 5 is confirmed, and when the process proceeds to step 6, the measurement of the weight of the drug container 2C is started. That is, the raw weight G of the medicine container 2C is measured and stored, and the current weight g of the medicine container 2C is monitored.

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

Then, the process proceeds to step 8 to start the timer timing. In the next step 9, while monitoring the change in the weight of the drug container 2 </ b> C per certain time, in step 10, it waits for a predetermined amount of powder to be dispensed.
That is, the change in the weight of the medicine container 2C is monitored, and it is confirmed in Step 9 that the weight reduction continues at least a certain amount per certain time. If at least a certain weight reduction continues for a certain period of time, since the medicine has fallen from the medicine container 2C normally, the process proceeds to Step 10, and whether or not a predetermined amount of powder has been dispensed in Step 10 Confirm. If the amount of powder dispensed is insufficient, the process returns to step 9. In this way, while confirming the dropping of the medicine in Steps 9 and 10, it waits for a predetermined amount of powder to be dispensed.
That is, in step 10, the process waits until the difference between the original weight G of the medicine container 2C and the current weight g becomes a desired payout amount. When the desired payout amount is reached, the process proceeds to step 11 to stop the vibration of the shaking table 20.

  The subsequent steps are the same as those of the known medicine dispensing apparatus 100, and the medicine is divided and scraped out and packaged individually.

  Moreover, if the weight reduction of the medicine container 2C has stopped before reaching the desired payout amount, the continuation of the powder falling cannot be confirmed, and it is expected that the medicine in the medicine container 2C is insufficient. Then, the process proceeds to step 14, an error display indicating that the powder is insufficient is displayed, and the series of processes is completed.

When a series of discharge processes and packaging processes 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 unique configuration of the medicine dispensing device 100 of the present embodiment, when the medicine container moving device 102 is operated to return the medicine container 2C to the original position, the total weight of the medicine container 2C is reweighed. More specifically, when the medicine container 2C is returned to the original position, the medicine container 2C is once transported to the medicine container inlet 151, and the medicine container 2C is placed on the weight measuring means 152 provided in the medicine container inlet 151. Then 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) and the total weight of the drug container 2C after the drug discharge are compared. Then, it is confirmed that the difference between the two matches the amount of the medicine discharged in the above-described process. That is, a discharge amount confirmation process is performed.
Alternatively, the weight of the medicine container 2C by the weight measuring means 152 provided in the medicine container inlet 151 is compared with the weight of the medicine container 2C after the medicine discharge measured by the medicine feeder 50, and the two are matched. Check. That is, a test step is performed to determine whether the weight measuring means 25 of the medicine feeder 50 is accurate.
If the total weight of the medicine container 2C is normal as a result of re-weighing the medicine container 2C, the medicine container moving device 102 is operated to return the medicine container 2C to the original position. If there is an abnormality in the total weight of the medicine container 2C, an alarm is immediately issued to notify the pharmacist.

Next, a method of using the second type drug container 2B and the fourth type drug container 2E, which are two-sided open types, will be described.
The drug containers 2B and 2E of the second and fourth forms are used when manually packing powder or the like. That is, there are drugs that are not frequently used, drugs that are highly toxic, drugs that are not appropriate to be stored in the drug container storage shelf 101 of the drug dispensing device 100 for reasons such as high hygroscopicity or weakness to high temperatures. Or it may be necessary to crush and prescribe tablets and capsules.
In such a case, the second and fourth type drug containers 2B and 2E are fixed to the shaking table 20 of the drug feeder 50, and a rough amount of drug is put into the drug containers 2B and 2E from the opened upper side. To do. When using the medicine container 2E of the fourth form, the large lid 301 is removed, the opening 300 is opened, and the medicine is charged through the opening 300. Thereafter, 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.
Thereafter, the vibration of the shaking table 20 is started and the distribution tray 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 a desired dispensing amount. wait. When the desired payout amount is reached, the vibration of the shaking table 20 is stopped.

In the embodiment described above, the powder feeder is supplied to the distribution tray 212 of the powder distribution device 202 using the drug feeder 1, 50, but even if the powder powder is supplied directly from the drug feeder 1, 50 to the drug packaging device 203. Good.
It is also conceivable to supply tablets and capsules using the drug feeder 1,50 of the present invention.

  In the embodiment described above, in the medicine feeders 1 and 50, the contact sensors 33a, b, c, and d are provided at the four corners of the vibration table 20, but the number of contact sensors is arbitrary. However, in order to determine whether the vibration table 20 is in close contact with the bottoms of the drug containers 2A, 2B, 2C, 2D, 2E, at least two contact sensors are provided in the longitudinal direction of the vibration table 20. It is desirable that In order to confirm that the axes of the medicine containers 2A, 2B, 2C, 2D, and 2E coincide with the axis of the vibration table 20, at least two contact sensors in the width direction of the vibration table 20 are used. It is desirable to be 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 powder discharge amount. However, the discharge amount of the powder 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 weight detected by the weight measuring means 25 immediately after the drug containers 2A, 2B, 2C, 2D, 2E are installed on the shaking table 20 is defined as the original weight G, 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 powder discharge amount.

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

In the above-described embodiment, the electromagnets 30a and 30b are energized and the drug container 2 is fixed to the vibration table 20. However, a permanent magnet is used or the drug container 2 is combined with a vibration table using a permanent magnet and an electromagnet. You may fix to 20.
More specifically, instead of the electromagnets 30a and 30b, a non-excited electromagnet or a magnet having a structure called a self-holding solenoid is used as the container holding means.
The above-described self-holding solenoid or the like is a combination of a permanent magnet and an electromagnet, and always exerts an attractive force mainly by the permanent magnet. When the magnetized magnet is removed 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 magnet is energized to generate a magnetic force in the same direction as that of the permanent magnet at the time of adsorption, and a current in the reverse direction is supplied to generate a magnetic force in the direction opposite to that of the permanent magnet at the time of separation.

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 shown in FIGS. 19 to 25 even when the self-holding solenoid is employed. The container holding means will be described as self-holding solenoids 30a and 30b with reference to FIGS.
In the case where 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 unloading operation of the medicine container 2 is started in Step 2 described above.
And the carrying-out operation | work of the chemical | medical agent container 2 is started similarly to previous embodiment. A drug container 2 </ b> C containing a drug that matches 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.

The energization of the self-holding solenoids 30a and 30b is stopped, and the magnetic force of the permanent magnet is exhibited to fix the drug container 2 to the vibration table 20.
The following steps are the same as those in the above-described embodiment, but when the medicine container 2 is detached from the vibration 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 attracting force when not energized, the power consumption is less than the configuration using the electromagnets 30a and 30b. In that respect, the configuration employing the self-holding solenoids 30a, 30b is superior to the configuration employing the electromagnets 30a, 30b.
The self-holding solenoids 30a and 30b have low power consumption and a small amount of heat generation. Therefore, it is also recommended in that the influence on the medicine in the medicine container 2 is small.

  In the embodiment described above, the protrusion 16 is provided on the medicine container 2C side and engaged with the main body device 3 side to prevent the medicine container 2C from moving forward. However, the protrusion is provided on the main body device 3 side to provide the medicine container 2A. , 2B, 2C, 2D, 2E, or a configuration in which a recess is provided in the medicine container 2 is also effective.

  In the embodiment described above, the vibration isolation members 40 and 41 are exemplified by a combination of a spring and a vibration damping rubber. However, a vibration isolation member using a single spring may be employed, and the vibration isolation member 40, 41 may be made of only resin or the like. A vibration isolating member may be employed.

  In the embodiment described above, the anti-vibration member 40 is provided between the intermediate base 22 and the anti-vibration base 23 so as to prevent vibration from being transmitted to the anti-vibration base 23. Instead, it is also recommended to remove the effects of vibration by software. For example, a method of removing the influence of vibration by Fourier transforming the detection value of the weight measuring means 25 is conceivable.

In the embodiment described above, the total weight of the drug container 2C is re-weighed using the weight measuring means 152 provided in the drug container inlet 151. However, the weight measuring means is provided in another part of the drug container 2C. The total weight may be reweighed. In addition, the medicine container 2C may be replaced with another medicine feeder 1 and 50 from the medicine feeder 1 and 50 used for discharging the medicine, and the total weight may be measured again. That is, by re-weighing, if it is discovered that there is some abnormality in the measured value, it will also lead to detecting a failure of any of the weight measuring means 25, 152 compared.
Moreover, 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 a desired payout amount. 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.

  In the embodiment described above, the weight of the medicine container 2C is monitored to decrease and it is confirmed that the medicine continues to fall. However, a powder fall sensor is provided separately, and the powder fall sensor is used. It may be confirmed that the medicine continues to fall.

In the embodiment described above, the container moving means employs a type having the hand 45 (FIG. 1) of the type that grips the drug container 2 or a type having the hand part 112 (FIG. 30) using an electromagnet. In the former hand 45, the hand 45 itself operates independently from the arm. The latter hand unit 112 itself is integral with the arm and does not move relatively, and holds the drug container 2 by physical adsorption.
In addition, a hand for holding the medicine container 2 by physical fitting or engagement is conceivable.
For example, like the combination of the medicine container 2F and the hand 172 shown in FIG.
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 surfaces.
One hand 172 is provided with a groove 175 having a “C” cross-sectional shape. The groove 175 is open at the front end side in the longitudinal direction as shown in the figure. The rear end in the longitudinal direction of the groove 175 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. I can't do it.
The hand 172 is integrally attached to the robot arm.

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

In addition, the main body device 3 includes members to be energized such as electromagnets 30a and 30b, self-holding solenoids 30a and 30b, vibration means (piezoelectric elements), and is likely to generate heat. When there is a concern that the heat generation affects the medicine in the medicine container 2, it is desirable to provide a cooling means for cooling the main body device 3.
As an example of the cooling means, a configuration in which a cooling fin 305 is provided in the main body device 3 as shown in FIG. 46 or a blower 306 is provided in the vicinity.

Further, as a further developed configuration, a configuration that can change the vibration pattern of the shaking table 20 in accordance with the drug type, the discharge timing, and the total discharge amount is recommended.
Drugs vary in particle size and hygroscopicity depending on the type. Therefore, when the vibration table 20 is vibrated, the behavior of the medicine in the medicine container 2 varies depending on the medicine.
Some drugs are easy to flow when rectified and others are difficult to rectify. Further, the amount of movement with one vibration varies depending on the type of medicine.
In addition, there is a problem that the amount of medicine discharged is not stable at the initial stage of medicine discharge.

Therefore, the vibration frequency (frequency) per unit time and the amplitude can be changed, and the frequency and amplitude are changed according to the drug type, the discharge timing, and the total discharge amount.
For example, the drug discharge easiness is tested in advance, and all the drugs scheduled to be discharged by the drug feeders 1 and 50 are divided into a plurality of stages. This is referred to as “flow coefficient”, for example, and the medicine is divided from flow coefficient 1 to flow coefficient 3.
The discharge level is divided into a plurality of stages according to the total discharge amount of the medicine. For example, the discharge amount is divided into 20 gram units and called as “discharge amount 20, discharge amount 40, discharge amount 60”.
The vibration level is divided into a plurality of stages according to the vibration frequency and amplitude. This is referred to as “vibration level 1, vibration level 2”, for example, and 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 “flow coefficient” and “discharge amount”. Moreover, the vibration level distinguishes the vibration level in the initial stage of discharge from the vibration level in the stable period.
For example, when the drug is easy to be discharged such as “flow coefficient 1” and the total discharge amount is small such as “discharge amount 20”, the vibration starts with a slow vibration such as vibration level 3, When a certain time elapses, the vibration level is switched to a stronger vibration level 10. Alternatively, the vibration intensity of the vibration table 20 is switched to a method in which the vibration intensity of the vibration table 20 is feedback-controlled so that the amount of discharge h per unit time is constant around a strong vibration such as the vibration level 10.

  If the drug is difficult to be discharged such as “flow coefficient 3” and the total discharge amount is large such as 80, the vibration starts with a strong vibration such as the vibration level 11 and a certain time When the time elapses, the vibration level is switched to a stronger vibration level 15. Alternatively, feedback control is performed so that the discharge amount h per unit time is constant with a strong vibration as the vibration level 15 as the center.

In addition, it is desirable to provide a test function for testing whether the weight measuring means 25 of the medicine feeders 1 and 50 is accurate.
For example, an existing weight member having a weight is prepared, and the weight is set in the medicine shelf region 103 or the like. Then, the weight member is moved to the vibration table 20 by the robot 43 and the weight measuring means 25 measures the weight of the weight member. If the measured value matches the weight of the weight, the weight measuring means 25 is accurate, and if it is different, the weight measuring means 25 is out of order.
Moreover, the chemical | medical agent container 2 itself can also be utilized as a weight member. For example, harmless powder or granular material is put in the medicine container 2 and its weight is measured in advance. The drug container 2 used as a weight member is installed in the drug shelf region 103 and the like together with the other drug containers 2. Then, if necessary, the weight medicine container 2 is moved by the robot 43 or the like and placed on the vibration table 20, and the weight measuring means 25 is verified.

A method for installing the drug container 2 in the drug shelf region 103 is arbitrary. For example, as shown in FIG. 47, a drug shelf 328 provided with a plurality of vertical walls 320 and mounting tables 323 is conceivable. 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 engagement portion 325 and the lower engagement portion 326 are maintained in a state of protruding by an urging member (not shown).
In this embodiment, the drug container 2 to be employed is provided with an engagement protrusion 370 on the lid member 120D in addition to the configuration of the drug container 2D of the fourth form. There is a recess 371 at the rear end of the medicine container 2D.
The upper engaging portion 325 rotates upward as indicated by an arrow as shown in the figure by pressing the lid member 120D of the medicine container 2D. The lower engaging part 326 is immersed in the mounting table 323 by pressing the iron plate part 6 of the medicine container 2.
When the medicine container 2 is pressed against the medicine shelf 328, the upper engaging portion 325 and the lower engaging portion 326 escape against the force of the urging member. When the medicine container 2D reaches a predetermined position, the upper engaging portion 325 is returned by an urging member (not shown) and engaged with the engaging protrusion 370 of the lid member 120D. Further, the lower engaging portion 326 is returned by an urging member (not shown), and engages with the recess 371 at the rear end portion of the medicine container 2D.
When taking out the medicine container 2D, the medicine container 2D is held by the robot 43 or the like and pulled away 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 can be disengaged.

For example, as shown in FIG. 48, a medicine shelf 345 provided with a plurality of vertical walls 340 and mounting tables 343 is conceivable. The vertical wall 340 has an opening 346, and a protrusion (storage portion side upper engagement portion) 347 protrudes upward in the opening 346.
The mounting table 343 is provided with a storage unit-side lower engagement portion 348. The storage unit side lower engagement portion 348 is a protrusion.
In the present embodiment, the drug container 2 to be employed has a recess 350 at the rear end portion like the drug container 2D of the fourth form. A container-side engagement portion 352 is provided on the peripheral wall lower surface 12D of the container main body 5D. The position of the container side engaging part 352 is the position of the peripheral wall lower surface 12D and slightly closer to the lid member 120D than the center. The container side engaging part 352 is ring-shaped, and is provided with a square hole 351 penetrating in the longitudinal direction of the medicine container 2D.

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

  Among the drug containers 2 described above, in principle, the drug container 2 having a lid is to remove the lid member 120 and put the drug in, but the drug container 2E of the fifth embodiment has a movable lid part 134E. Since it is easy to remove the medicine, the medicine can be put in without removing the lid main body 125E. At that time, as shown in FIG. 45, if the funnel-shaped member 355 is attached to the movable lid portion 134E and the operation is performed, it is difficult for the medicine to spill.
