Description

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

In recent years, large hospitals and large-scale pharmacies have introduced powder dispensing devices and drug dispensing devices having a powder packaging function. Here, the powder packaging device is a device that individually packages powders and the like for each dose. If a powder packaging device is used, most of the work of packaging powders and the like in doses can be automated.
The powder packaging device 200 disclosed in Patent Document 1 is a device for individually packaging powders for each dose, and as shown in FIG. 39, the drug supply device 201, the powder distribution device 202, and the drug packaging are inside. It has a device 203.
The drug supply device 201 disclosed in Patent Document 1 is composed of a charging hopper 205 and a powder feeder 206, as shown in FIGS. 39 and 40.
As shown in FIG. 40, the powder feeder 206 is provided with two piezoelectric elements 207 and 208 under the trough 210 to vibrate the trough 210.

As shown in FIG. 39, the powder distribution device 202 is composed of a distribution plate 212 and a scraping device 215. The distribution plate 212 has an arcuate cross section and has an annular groove 216 in plan view. The distribution plate 212 is rotated at a constant speed by the motor 219.
The scraping device 215 has a disc 217 that moves up and down and rotates, and the scraping plate 218 is provided on the disc 217.

As shown in FIG. 39, the drug packaging device 203 is composed of a packaging hopper 220 and a packaging device 221.

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

Then, 60 grams of the weighed powder is charged into the charging hopper 205 of the drug supply device 201.
At the same time, the piezoelectric elements 207 and 208 (FIG. 40) of the powder feeder 206 are energized to vibrate the trough 210, and the distribution pan 212 is further rotated at about 20 to 30 revolutions per minute.
The powder charged into the charging hopper 205 falls from the opening at the lower end of the charging hopper 205 to the trough 210 of the powder feeder 206. Then, as the trough 210 vibrates, the powder slowly moves to the tip side and is rectified. Further, while moving on the trough 210, rectification proceeds, and the flow of the drug becomes a laminar flow state. That is, the distribution of the drug in the cross section in the direction orthogonal to the flow is constant, and the distance that the drug travels per unit time is also constant. As a result, 60 grams of powder is evenly dispersed and slowly moves towards the tip at a constant rate per hour.
Finally, the powder that moves at the head reaches the tip of the trough 210, and the powder that moves at the head falls from the tip of the trough 210 into the groove 216 of the distribution plate 212. Further, the powder powder that follows will fall into the distribution plate 212 by a certain amount per hour. Finally, the last powder drops into the distribution dish 212, and all 60 grams of powder enters the groove 216.

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

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

By using the powder packaging device 200 disclosed in Patent Document 1, most of the work of packaging the powder in doses can be automated.
However, it cannot be said that the powdered powder packaging device 200 of the prior art is a device that can completely automate the packaging of powdered medicine because there are still steps that must be manually performed.
That is, in the prior art powder packaging device 200, it is essential that the pharmacist takes out a medicine bottle containing a desired powder from the medicine rack and weighs a predetermined amount of powder from the medicine bottle.
Therefore, the applicant has developed a drug feeder equipped with a weight measuring means and filed a patent application in order to automate the work of weighing powder (Patent Document 2).

The drug feeder disclosed in Patent Document 2 is composed of a container placing device and a drug container. The container mounting device is provided with a shaking table, a vibrating means, and an electromagnet, and the drug container can be fixed to the shaking table by the electromagnet.
The drug feeder disclosed in Patent Document 2 vibrates a shaking table to charge a drug from a drug container into a distribution dish. Then, the weight of the drug container at that time is monitored by a weight measuring means, and when a certain amount of drug is discharged, the vibration of the shaking table is stopped.

Japanese Unexamined Patent Publication No. 2000-85703 International Publication No. 2014-46148

According to the drug feeder disclosed in Patent Document 2, the work of weighing out a predetermined amount of powder can be omitted.
However, when the drug feeder disclosed in Patent Document 2 was prototyped and repeated experiments were conducted to examine the difference between the target discharge amount of the drug and the actual discharge amount, there was an error of about 0.5 g between the two. I noticed that there are many cases.
Therefore, it is an object to solve this problem and develop a drug feeder capable of discharging a more accurate amount of drug.

The present inventors have pursued the cause of the error in the emission amount. As a result, it was found that the elasticity of the electric wire connecting the drug feeder and the outside is the cause of the error.
That is, the drug feeder disclosed in Patent Document 2 has an electromagnet for fixing the drug container and a vibrating means for vibrating the drug container, and has an electric wire for supplying power to these. There is also an electric wire for outputting the signal of the weight measuring means to the outside.
Although these electric wires are thin, they are physically connected to the main body, and their weight and elastic force slightly affect the detection value of the weight measuring means.
Further, the drug feeder disclosed in Patent Document 2 has a shaking table, and the main body vibrates during use. Therefore, the vibration of the shaking table is transmitted to each electric wire, and each electric wire vibrates. As a result, the position and the degree of bending of the electric wire change while the chemical is being discharged, causing an error of about 0.5 g in the measured value.

A mode developed based on the above findings is a drug container and a drug feeder having a container mounting device, and the drug container is removable from the container mounting device, and the drug container has a form. There is a drug discharge unit that discharges the drug, and the container mounting device includes a shaking table, a vibrating means for vibrating the shaking table, a container holding means for temporarily fixing the drug container to the shaking table, and the weight of the drug container. The drug container is placed on a shaking table, the drug container is fixed to the shaking table by the container holding means, and the shaking table is vibrated from the drug discharging unit. A wire holding member capable of discharging a drug little by little and detecting the amount of the drug discharged by a weight measuring means, having one or more electric wires connected to the outside, and holding all or any of the electric wires. The electric wire holding member has an electric wire fixing portion and holds the electric wire by the electric wire fixing portion, and the electric wire holding member has elasticity and the position of the electric wire fixing portion moves according to an external force. It is a drug feeder characterized in that the electric wire fixing portion returns to the original position when the is disappeared.

In the drug feeder of this embodiment, the drug container is fixed to the shaking table, and the drug container is brought into direct contact with the shaking table. By vibrating the shaking table in this state, the whole or part of the drug container can be vibrated. Therefore, the drug in the drug container slowly moves to the drug discharge section side, the drug is rectified, the flow is laminarized, and the drug is discharged from the drug discharge section.
Further, since the drug feeder of this embodiment is equipped with a weight measuring means, it is possible to detect the discharge amount of the drug and automate the work of weighing out the powder or the like.
Further, the chemical feeder of this embodiment has an electric wire holding member, and the electric wire is held by an electric wire fixing portion of the electric wire holding member. The wire holding member has elasticity, and the position of the wire fixing portion moves according to an external force, and when the external force disappears, the wire fixing portion returns to the original position. Therefore, it is possible to prevent the position and the degree of bending of the electric wire from changing while the chemical is being discharged, and the problem that an error occurs in the measured value is solved.

In one embodiment, the drug container is partially or wholly made of a magnetic material, the container holding means has a magnet member and fixes the drug container by magnetic force, and a magnet energizing wire connected to the magnet member is added. A configuration having a vibrating means energizing wire connected to the shaking means and a measuring means energizing wire connected to the weight measuring means can be considered.

It is recommended that the wire holding member be partially or wholly a coil spring.

It may have a plurality of electric wire holding members.

The container holding means has a permanent magnet and an electromagnet, and at least the drug container is fixed to the shaking table by the magnetic force of the permanent magnet, and the electromagnet is energized to generate a magnetic force that cancels the magnetic force of the permanent magnet to generate a shaking table of the drug container. It is desirable to release the fixation to.

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

There are one or more coiled members in the drug container, and at least one of the coiled members is in a horizontal position where the axis intersects the flow direction of the drug generated by vibrating the shaking table. Moreover, it is desirable that the coil has a degree of freedom in the vertical direction and moves up and down by the vibration of the shaking table.

In the drug container, the powdery drug may be agglomerated. According to this aspect, since the movable coil moves up and down by the vibration, the mass is crushed and the medicine is smoothly discharged.

An eaves member that covers the upper part of the movable coil is provided, and the eaves member is provided with an opening. The opening is located directly above the movable coil, and the drug that rides on the eaves member falls from the opening to the movable coil. Is desirable.

In the drug feeder of this embodiment, since the drug falls directly into the movable coil, the action of crushing the mass is strong.

There are two or more coiled members in the drug container, and at least one of the coiled members is placed horizontally, in a posture in which the axis intersects the flow direction of the drug, and has no degree of freedom in the vertical direction. It is desirable that it is a fixed coil.

In the drug feeder of this embodiment, the coiled member functions as a rectifying member. In addition, the powdered drug mass can be disintegrated and returned to the original powder form.

There are two or more coiled members in the drug container, and at least one of the coiled members is placed horizontally and is in a posture in which the axis intersects the flow direction of the drug generated by vibrating the shaking table. It is a movable coil that has a degree of freedom in the vertical direction and moves up and down by the vibration of the shaking table. At least one of the coiled members is placed horizontally and the axis line intersects the flow direction of the drug. Moreover, it is a fixed coil having no degree of freedom in the vertical direction, and it is desirable that the fixed coil is located on the downstream side of the movable coil in the flow direction of the drug.

As described above, the movable coil has a function of crushing a mass of a drug. Further, as described above, the fixed coil has a function as a rectifying member.
If there is a lump in the drug, it will be crushed by the moving coil. However, in this state, the thickness of the drug layer is uneven.
In this embodiment, since the fixed coil is located on the downstream side of the movable coil, the crushed and powdered drug is smoothed and changed into a thin layer having a certain thickness.

The original weight, which is the weight of the drug container before the drug is discharged, is measured by the weight measuring means, and when the shaking table is vibrated to discharge the drug little by little from the drug discharging section, the weight of the drug container is measured by the weight measuring means. It is desirable to have a measuring function to monitor and stop the vibration of the shaking table when the current weight, which is the current weight of the drug container, matches or substantially matches the value obtained by subtracting the target emission amount from the original weight.

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

It is desirable to monitor the weight of the drug container and change the vibration pattern of the shaking table when the change in the weight of the drug container per unit time is less than a certain level.

The reason why the change in the weight of the drug container per unit time is less than a certain value is considered to be that the drug has solidified in the drug container.
Therefore, when the change in the weight of the drug container per unit time becomes less than a certain value, the vibration pattern of the shaking table is changed to loosen the lumps. For example, the vibration pattern is changed so that the amplitude of the shaking table becomes large.

If the change in the weight of the drug container per unit time is less than a certain value even if the vibration pattern of the shaking table is changed, it is desirable to stop the vibration of the shaking table and execute a predetermined shortage processing step.

It is considered that the remaining amount of the drug in the drug container has decreased as the cause when the change in the weight of the drug container per unit time is less than a certain value even if the vibration pattern of the shaking table is changed.
Therefore, the vibration of the shaking table is stopped, and a predetermined shortage processing process is executed.

In the shortage processing process, the weight of the medicine that has already been discharged is memorized, and when the medicine container is remounted and then restarted automatically or manually, when the total discharge amount matches or substantially matches the target discharge amount. It is desirable to stop the vibration of the shaking table.

According to this aspect, even if a shortage occurs before the specified amount of discharge is reached, if the missing chemical is replenished and the discharge is restarted, the completed discharge amount before the replenishment is stored. , The amount that must be discharged after replenishment can be calculated. Therefore, it is not necessary to collect the already discharged drug and discharge it from the beginning again, and the work efficiency is high.

It is desirable to change the vibration pattern of the shaking table when the amount of chemicals discharged approaches the target amount.

For example, when the amount of the drug discharged becomes the target amount minus a constant amount (sufficiently smaller than the target amount), the amplitude of the shaking table is reduced or the vibration frequency is lowered.

The drug container has a container body that opens on one side and a lid member that constitutes a drug discharge portion and is detachably attached to the opening of the container body. The lid member has an engaging piece and is an outer periphery of the drug container. The portion has a recess, and there is a swing member that covers the recess and swings with respect to the container body, an engaging piece of the lid member is arranged in the recess, and a part of the swing member is engaged. The lid member may be fixed to the container body by engaging with the piece.

In addition, the drug container has a main body that is almost entirely covered and has a space inside, and a raised bottom member is provided at a position deeper than the drug discharge portion based on the posture of the drug container mounted on the container mounting device. When the drug container is in the vertical position, the drug inside may not reach deeper than the raised bottom member.

The drug feeder of this embodiment is suitable for packaging a small amount of a drug at a time.
As a result, a drug with a small prescription amount is consumed (sales amount) within a certain period of time. Therefore, the amount of stock is small, and when the above-mentioned drug is stored in a normal-sized drug container, the empty space in the drug container becomes wide, and the drug may be absorbed by water vapor in the space.
According to the drug feeder of this embodiment, the space for accommodating the drug in the drug container is narrowed, and the drug is less likely to get wet.
The drug feeder of this embodiment is also suitable for packaging a drug that is rarely prescribed.
Further, the drug feeder of this embodiment is suitable for storing the drug container in a vertical position and placing the drug container in a horizontal position with respect to the container placing device.
When a drug container containing a small amount of drug is stored in a vertical position, the drug concentrates on the portion corresponding to the bottom. When this container is placed in the container mounting device in a horizontal position, the drug is biased to a portion (back side) farther than the drug discharge portion.
Here, the drug feeder of the present embodiment vibrates the whole or part of the drug container by vibrating the shaking table, and slowly moves the drug in the drug container to the drug discharge portion side. When the amount of the drug contained in the container is small, it takes time for the drug accumulated in the back to reach the drug discharge portion.
In this aspect, it was developed as a drug container for storing a small amount of drug, and since the drug inside does not reach deeper than the raised bottom member, the drug is used after the shaking table vibrates. The time required to reach the discharge part is short.

The drug container may have an opening on the upper surface side thereof based on the posture of being mounted on the container mounting device, and the drug may be charged into the drug container through the opening.

The drug feeder of this embodiment is suitable for packaging a drug that is rarely prescribed. The drug feeder of this embodiment is also suitable for packaging a drug obtained by crushing a tablet into powder or a drug prepared by mixing a plurality of drugs in a mortar. The drug feeder of this embodiment is also suitable for packaging drugs that are not suitable for storage in a drug container.

Further, the drug container has a storage space forming member and a bottom forming member, the storage space forming member has at least a side wall covering the side surface and has an opening at the bottom, and the bottom forming member is a part or all of the magnetic material. The storage space forming member may be detachable from the bottom forming member, and the container holding means may have a magnet member and fix the drug container by magnetic force.

The drug feeder of this embodiment is also suitable for packaging a drug that is rarely prescribed. The drug feeder of this embodiment is also suitable for packaging a drug obtained by crushing a tablet into powder or a drug prepared by mixing a plurality of drugs in a mortar. The drug feeder of this embodiment is also suitable for packaging drugs that are not suitable for storage in a drug container.

There is an elastic body between the storage space forming member and the bottom forming member, and the total length of the bottom forming member in the horizontal direction with respect to the posture mounted on the shaking table of the container mounting device is the horizontal of the storage space forming member. It is longer than the total length in the direction, and the tip of the bottom forming member becomes the drug discharge part, the drug container is placed on the shaking table, the drug container is fixed to the shaking table by the container holding means, and the shaking table is vibrated. It is desirable that the drug that has fallen from the opening of the forming member to the bottom forming member travels on the bottom forming member, and the drug is discharged little by little from the drug discharging portion.

According to this aspect, the vibration of the shaking table is not easily transmitted to the storage space forming member, and the movement of the drug is smooth.
In the drug feeder of this embodiment, there is an elastic body between the storage space forming member and the bottom forming member, and the structure is such that the two are cut off. Therefore, the bottom forming member directly receives the vibration from the shaking table and vibrates greatly, but the storage space forming member placed on the upper side vibrates less. Thus, in this embodiment, the vibration of the storage space forming member and the vibration of the bottom forming member are not synchronized.
Therefore, the drug in the storage space forming member falls on the bottom forming member, smoothly moves through the bottom forming member, and is discharged from the drug discharging portion at the tip.

When the shaking table 50 starts to vibrate, the drug container 2 vibrates. Here, in the present embodiment, the drug container 2 is firmly joined to the shaking table 50 by the permanent magnets of the magnet members 62a and 62b, and the degree of adhesion to the shaking table 50 is high. It vibrates at the same frequency as the shaking table 50. As a result, the powder stored in the powder storage unit 17 of the drug container 2 slowly moves toward the drug discharge unit 13.

Then, the powdered medicine passes through the rectifying unit 20. The powdered drug that has passed through the rectifying section 20 flows like a river, and finally reaches the drug discharging section 13 of the drug container 2, falls like a waterfall, and enters the groove of the distribution plate 116 below.

The fact that the powder is falling is confirmed by the weight reduction of the drug container 2. That is, in the present embodiment, the current weight (current weight g) of the drug container 2 is continuously monitored by the weight measuring means 55 even while the powder is falling from the drug discharge unit 13 of the drug container 2. Then, the original weight G of the drug container 2 immediately after being installed on the shaking table 50 is compared with the current weight g, and the amount of powder dropped H (G minus g) is constantly calculated.
Then, when the total drop amount H of the powder reaches a desired weight, the vibration of the shaking table 50 is stopped.
That is, when the current weight g of the drug container 2 measured by the weight measuring means 55 is less than the original weight G before the start of vibration measured by the weight measuring means 55 by a desired weight, the vibration of the shaking table 50 is stopped. ..
Further, before stopping the vibration of the shaking table 50, it is desirable to operate the shaking table 50 in a state where the amplitude of the shaking table 50 is reduced and the vibration frequency is lowered.
For example, when the current powder discharge amount is the amount obtained by subtracting several grams from the final discharge amount of powder (target discharge amount), the amplitude of the shaking table 50 is reduced and the vibration frequency is lowered. Drive in a state of being. Then, the remaining several grams are discharged in a state where the amplitude of the shaking table 50 is reduced and the vibration frequency is lowered.
Then, as described above, the vibration of the shaking table 50 is stopped when the total drop amount H of the powder reaches a desired weight.
After that, the container moving means 700 automatically operates, and the medicine container 2 is returned to the drum member 107 of the medicine shelf region 102.

Further, when the powder does not fall even though the shaking table 50 continues to vibrate, or when the shaking table 50 continues to vibrate, the amount of powder falling per unit time is excessive. When the number has decreased, the vibration pattern of the shaking table 50 is automatically changed.
Specifically, when the weight of the drug container 2 is continuously monitored while vibrating the shaking table 50, the unit of weight of the drug container 2 is a unit of the weight of the drug container 2 even though the amount of powder H dropped does not reach the desired weight. When the change per hour becomes less than a certain value, the amplitude of the shaking table 50 is increased. Alternatively, the amplitude frequency is increased or decreased. Also, if possible, add lateral and longitudinal amplitudes.

Despite vibrating the shaking table 50, the change in the weight of the drug container 2 per unit time is less than a certain value in the following two points.
(1) Sticking of powder The powder sticks in the drug container 2 or becomes a lump and cannot pass through the rectifying unit 20.
(2) Insufficient powder There is no powder in the drug container 2.

Therefore, in the present embodiment, when the change in the weight of the drug container 2 per unit time is less than a certain value even though the shaking table 50 is vibrated, it is first suspected that the powder is stuck and the shaking table 50 is used. Increase the amplitude of. If the cause is sticking of powder, the cause may be eliminated by increasing the amplitude of the shaking table 50.

If the change in the weight of the drug container per unit time is less than a certain value even if the amplitude of the shaking table 50 is increased, the vibration of the shaking table is stopped and a predetermined notification is given to the user. .. For example, an abnormality display is made on a display device (not shown). Alternatively, the user is notified that an abnormality has occurred in the drug dispensing device 100 by voice, alarm sound, or light.
Then, a predetermined shortage processing process is executed.
In the shortage processing step, the weight of the drug already discharged from the drug container 2 is stored.
The user who knows that an abnormality has occurred will take out the drug container 2 manually or by using the container moving means 110 and inspect it.

In the present embodiment, in the shortage processing step, the drug container 2 is taken out by using the container moving means 110. That is, even if the amplitude is increased, if the change in the weight of the drug container 2 per unit time is less than a certain value, the vibration of the shaking table is stopped and the container moving means 110 automatically operates, and the drug container 2 is operated. Is moved to a drug container temporary storage portion (not shown) provided with a door portion 130.
When the drug container 2 is installed in the drug container temporary storage portion (not shown) provided in the door portion 130, the door portion 130 automatically opens. The user takes out the drug container 2 from the temporary storage portion of the drug container and inspects the inside of the drug container 2. If there is no powder in the drug container 2, the drug container 2 is replenished with the drug. If the powder is lumped in the drug container 2, the lump is crushed.

After that, the medicine container 2 is placed on the container mounting device 3 again manually or by using the container moving means 110, and the shaking table 50 and the distribution pan 116 are restarted automatically or manually. In the present embodiment, the drug container 2 is installed in the drug container temporary storage portion (not shown) provided with the door portion 130, and by performing a predetermined operation, the container moving means 110 operates and the drug container 2 is operated. It is carried to the container mounting device 3.
As described above, since the weight of the drug discharged from the drug container 2 before the work is interrupted is stored, the powdered drug is discharged from the drug container 2 by the remaining amount of discharge.

Next, one of the peculiar actions of the drug feeder 1 of the present embodiment will be described. As described above, the drug feeder 1 of the present embodiment can detect the falling amount (discharge amount) H of the powder and discharge a predetermined amount of the powder from the drug container 2. The drug feeder 1 of the present embodiment has a small error in the amount of powdered medicine discharged.
That is, in the drug feeder 1 of the present embodiment, the difference between the target discharge amount and the amount of the drug actually discharged from the drug container 2 is small.
The reason for this will be described below.
In the drug feeder 1, electric wires (magnet energizing wire 65, vibrating means energizing wire 68, measuring means energizing wire 70) are drawn out from the container mounting device 3. Therefore, the container mounting device 3 receives some force from the electric wire, although it has a weak force.
In the prior art, the force received from the electric wire changes, causing an error in the measured value of the weight measuring means 55.

The drug feeder 1 of the prior art will be described. In the drug feeder 1 of the prior art, the electric wires (magnet energizing wire 65, vibrating means energizing wire 68, measuring means energizing wire 70) drawn from the container mounting device 3 are connected to a control device or the like (not shown). There were no rules regarding the withdrawal route or method, and it was a matter of course. That is, the electric wires were laid in the gaps between the devices, and the electric wires drawn from the container mounting device 3 were connected to the control device and the like.
Further, as a known method, a method of bundling electric wires or fixing or supporting the electric wires to a wall or the like may be adopted.

However, in either case, one end of the wire is on the container mounting device 3, and the next support of the wire is an immovable point.
That is, in the prior art, one end of the electric wire is fixed to the container mounting device 3, and the next support point after leaving the container mounting device 3 is a fixed point and does not move.
The drug feeder 1 has a shaking table 50 and has a structure in which the shaking table 50 is vibrated to discharge powder from the drug container 2. Therefore, the electric wire sways during vibration. Then, the posture of the electric wire may change slightly before and after the vibration.
That is, by vibrating the shaking table 50, the electric wire is shaken, and the bending condition of the electric wire is slightly changed. Briefly, the electric wire has some bending habit, but the bending habit changes when it receives vibration. As a result, the force received from the electric wire of the drug feeder 1 changes, and an error of about 0.5 g occurs in the measured value of the weight measuring means 55.

On the other hand, in the drug feeder 1 of the present embodiment, the relay point of the electric wire is movable. That is, in the drug feeder 1 of the present embodiment, the electric wire holding member 73 is provided on the installation plate 66. The electric wire holding member 73 is a spiral spring, and the upper end thereof moves arbitrarily according to an external force. In the drug feeder 1 of the present embodiment, the electric wire drawn from the container mounting device 3 is first relay-supported by the electric wire fixing portion 76 on the free end side of the electric wire holding member 73.
Therefore, the electric wire sways by vibrating the shaking table 50, and the sway is absorbed by the elasticity of the electric wire holding member 73. When the shaking table 50 stops vibrating, the electric wire holding member 73 returns to its original posture. Therefore, the bending condition and bending habit of the electric wire do not change before and after the vibration, the force received from the electric wire of the chemical feeder 1 does not change before and after the vibration, and the measured value of the weight measuring means 55 does not have an error.

FIG. 14 shows the behavior of the electric wire and the electric wire holding member 73 before and after the vibration. Before vibrating the shaking table 50, the electric wires between the stopper 71 and the electric wire fixing portion 76 of the electric wire holding member 73 are connected in a bent state as shown in FIG. 14A.
Then, when the shaking table 50 is vibrated, the electric wire sways, and the electric wire holding member 73 sways accordingly (FIG. 14b). Therefore, no excessive force is applied to the electric wire, and the bending habit of the electric wire does not change.
When the shaking table 50 stops vibrating, the wire holding member 73 returns to its original posture as shown in FIG. 14 (c). At this time, since the bending habit of the electric wire has not changed, the force received from the electric wire of the chemical feeder 1 before and after the vibration does not change, and the measured value of the weight measuring means 55 does not have an error.

Further, in the drug feeder 1 of the present embodiment, powdered medicine is smoothly discharged from the drug container 2 as a peculiar effect.
That is, the drug feeder 1 of the present embodiment has a rectifying unit 20 in the drug container 2 as a unique configuration. As a peculiar configuration, the rectifying unit 20 has two coils, one of which is a movable rectifying coil 26, which has a degree of freedom in the vertical direction. Therefore, when the shaking table 50 vibrates, the movable rectifying coil 26 also vibrates in the vertical direction.

Therefore, when the powder has a lump, the lump is destroyed by the vertical movement of the movable rectifying coil 26.
This point will be described below.
When the drug container 2 is installed in the container mounting device 3 and the shaking table 50 vibrates, the powder 80 in the drug container 2 slowly moves toward the drug discharge unit 13 side as shown by the arrow in FIG. It reaches the rectifying unit 20. There is a rectifying coil holding portion 27 on the rear end side of the rectifying portion 20, and the plan view is triangular. Therefore, the powdered drug that has reached the site is appropriately filtered and diffused.

Here, in the rectifying unit 20, the lower ends of the movable coil holding wall 32 and the tip closing wall 33 constituting the coil accommodating space 28 do not reach the bottom 46 of the container body 5, and as shown in FIG. 8, the bottom of the container body 5 There is a gap 48 between the 46 and the bottom opening of the coil accommodating space 28.
A notch 36 is provided at the boundary between the movable coil holding wall 32 and the tip closing wall 33.

Therefore, the powdered powder that has moved to the drug discharging section 13 enters the rectifying section 20 through the gap 48 and the notch 36 as shown in FIGS. 4 and 9. Most powders enter the rectifying section 20 through the gap 48 between the bottom 46 of the container body 5 and the bottom opening of the coil accommodating space 28 and pass under the rectifying section 20, but provide a notch 36. This makes it easier to introduce the powder into the movable rectifying coil 26 side from the outside.
Then, as described above, since the movable rectifying coil 26 moves up and down, the powder is hit by the wire rod of the movable rectifying coil 26, and if there is a lump, it is destroyed.
The powder then reaches the site of the fixed rectifying coil 25 downstream. The fixed rectifying coil 25 does not move up and down, and the powder passes through the gap between the wires to form a laminar flow.

That is, the movable rectifying coil 26 hits a lump of powder, and the lump collapses. However, in this state, there is a lump of powder that is crushed into a mountain shape, and the flow of powder does not become a laminar flow state.
Therefore, in the present embodiment, the fixed rectifying coil 25 is provided on the downstream side of the movable rectifying coil 26 to smooth the pile of powder.
As a result, the powder is in a laminar flow state, finally reaches the drug discharge section 13, and is discharged from the drug discharge section 13.

Further, a relatively large mass of the drug in the drug container 2 rides on the eaves lid (eaves member) 35 and falls from the opening 43 provided in the eaves lid 35 to the movable rectifying coil 26.
That is, when substances having different particle diameters are mixed, when this is vibrated in the vertical direction, the large particles move upward and the fine particles sink downward.
Therefore, when the drug container 2 is vibrated, the large lumps of particles float upward and proceed toward the drug discharge unit 13 in that state. Then, the mass rides on the eaves lid (eaves member) 35 and falls from the opening 43 provided in the eaves lid 35 to the movable rectifying coil 26.
The dropped mass is beaten by the wire of the movable rectifying coil 26 and crushed into small pieces.

In particular, when the powder contained in the drug container 2 is sticky such as lactose and the amount of the powder stored is large, the presence of the opening 43 is effective.
That is, when the filling amount of the powder is large, the powder moves to the drug discharging unit 13 due to vibration, but the powder stays in the vicinity of the rectifying unit 20. If the powder is sticky, the powder is compressed in the vicinity of the rectifying unit 20 to form a lump.
Here, in the present embodiment, the opening 43 is provided on the top surface of the coil accommodating space 28. The size of the opening 43 is such that the lump of powder is not clogged. Therefore, the mass enters the coil accommodating space 28 through the opening 43, falls into the movable rectifying coil 26, and is hit. As a result, the mass is eliminated and the powdered drug discharge is maintained.

In the embodiment described above, the drug feeder 1 adopting the closed type drug container 2 has been illustrated, but the drug container 81 having an open drug inlet as shown in FIG. 17 may be adopted. The drug container 81 has an opening 82 on the upper surface side thereof with reference to the posture mounted on the container mounting device 3, and the drug can be charged into the drug container through the opening 82.

Further, another modification of the drug container will be described with reference to FIGS. 21 to 24. The drug container 170 is a closed type container.
The drug container 170 is an improvement of the drug container 2 shown in FIGS. 1 to 9 described above, and although the design is different, the functions of the components are common in many respects. Therefore, the description of the drug container 170 will focus on the differences from the drug container 2 described above. Further, the same members as those in the previous embodiment are designated by the same numbers, and some description thereof will be omitted.

The inclined portion 181b on the back side is a gentle inclined surface, and the inclined portion 181a following it has a steep inclination. There is a gap 350 in the outer peripheral portion corresponding to the inclined portions 181a and 181a and b of the container body 5.

As shown in FIGS. 22 and 23, there is a step portion 160 on the outside of the peripheral wall upper surface 126 thereof, which is near the opening of the container body 5, and a low ceiling portion (recess) 161 made slightly lower in height. is there. An engaging member 162 (shown only in FIG. 22) is provided on the step portion 160.

A swing lid (swing member) 237 is attached to the low ceiling portion (recess) 161. As shown in FIG. 22, the swing lid 237 has a main body portion 163 having a size that completely covers the low ceiling portion 161 and a knob portion 164 protruding laterally from the main body portion 163. There is a hinge portion 167 at one end of the main body portion 163.
Further, engaging members 166a and 166b are formed on the lower surface side of the main body portion 163. The engaging members 166a and 166b have a hook shape.
In the swing lid 237, the hinge portion 167 is engaged with the container body 5 side, and the swing lid 237 swings around the hinge portion 167.

Next, the lid member 118 will be described. The lid member 118 has a lid main body portion 125 and a movable lid portion 134.
The movable lid portion 134 has a knob portion 147, and by pressing the knob portion 147, the movable lid portion 134 opens as shown in FIG. 23 (a). When the movable lid portion 134 is opened, the drug discharge section 13 that communicates with the inside and outside of the container body 5 is opened, and the movable lid portion 134 keeps the drug discharge section 13 open.
Further, on the rear end side of the lid main body 125, a desiccant insertion portion 15 and a rectifying portion 20 are provided as in the previous embodiment.
The lid main body 125 is made by joining two lid main pieces. Hereinafter, the state in which the two are combined will be described as a reference.
The lid main body portion 125 has a frame portion 127 on the front surface side, and a desiccant insertion portion 15 and a rectifying portion 20 are provided on the rear surface side.

Further, the frame portion 127 on the front side has a portion that functions as a fixing frame 131 and a portion that functions as a contact frame 132.
The area of the frame portion 127 surrounded by the fixing frame 131 is bottomed and has a shielding wall 138.
The area surrounded by the fixing frame 131 is a recess 373 as shown in FIGS. 22 and 23. A leaf spring 185 is provided on the surface of the shielding wall 138 in the recess 373 as shown in FIG. 23. The leaf spring 185 has mounting portions 186a and 186b at both ends as shown in FIG. 23. The region sandwiched between the two mounting portions 186a and 186b is the functional region 187, which is formed in a bent shape and has corners.

Further, an engaging plate (engaging piece) 192 extending in the horizontal direction is provided on the rear side of the lid main body 125 and in the vicinity of the upper portion thereof. The engaging plate 192 is provided with two engaging holes 193. Since the rear side (desiccant insertion portion 15 and rectifying portion 20) of the lid main body portion 125 is the same as that of the previous embodiment, detailed description thereof will be omitted.

Next, the movable lid portion 134 will be described. The movable lid portion 134 is composed of a pressing plate portion 145, an elasticity imparting portion 194, and a knob portion 147. The knob portion 147 is on an extension of the holding plate portion 145, and the knob portion 147 draws a curved surface slightly curved rearward from the plane of the holding plate portion 145.
A pad 236 is provided on the back surface side of the pressing plate portion 145.

Elasticity imparting portions 194 are provided on the left and right side portions of the pressing plate portion 145. The elasticity-imparting portion 194 has a hairpin-shaped elastic portion 235 whose shape is observed from above as shown in FIG. 22. The elastic portion 235 has a forward side portion 195 extending rearward as shown in FIG. 22 with the side of the holding plate portion 145 as a base end, and a return side portion 196 that is folded back in a "U" shape and reaches the front side. It has elasticity as a whole. A shaft piece 197 is provided on the outside of the return side portion 196. The free end side of the elastic imparting portion 194 is opened outward to form a knob portion 146.

Further, an engaging piece 149 protrudes from the back surface side of the holding plate portion 145. The engaging piece 149 has a rod shape or a plate shape, and is provided on the holding plate portion 145 in a cantilever shape. The engaging piece 149 is provided with a small protrusion 199.

The movable lid portion 134 is attached to the lid main body portion 125 by engaging the shaft piece 197 of the elastic imparting portion 194 with the bearing portion 140 of the lid main body portion 125.
At the time of installation, the knobs 146 on both sides are pressed in the direction of shortening the distance, the elastic part 235 is bent to shorten the distance between the left and right shaft pieces 197, and the movable lid is contained in the recess 373 of the lid body 125. The back surface side of the portion 134 is inserted, and in that state, the elastic portion 235 is returned to engage the left and right shaft pieces 197 with the bearing portion 140. When the movable lid portion 134 is removed, the elastic portion 235 is bent to reduce the distance between the left and right shaft pieces 197, and the left and right shaft pieces 197 are separated from the bearing portions 140a and 140b.

The lid member 118 is attached to the container body 5 as shown in FIGS. 23 and 24. In the state where the lid member 118 is attached to the container body 5, the engaging plate (engagement piece) 192 of the lid member 118 is connected from the front opening 239 of the swing lid (swing member) 237 as shown in FIG. 24 (a). Entering the internal space, the engaging members 166a and 166b of the swing lid 237 are engaged with the engaging hole 193 of the engaging plate 192.

That is, the engagement plate (engagement piece) 192 of the lid member (swing member) 118 is located in the low ceiling portion (recess) 161 formed on the outer periphery of the container body 5, and the lid member 118 is closed to form the low ceiling portion 161. The engagement plate (engagement piece) 192 of the lid member (swing member) 118 engages with the engagement plate (engagement piece) 192 of the lid member (swing member) 118, and the lid member 118 is the container body 5 Is fixed to.

When the swing lid 237 is opened as shown in FIG. 24 (b), the engagement members 166a and 166b of the swing lid 237 and the engagement hole 193 of the engagement plate 192 are disengaged. Therefore, the lid member 118 can be easily removed from the container body 5 as shown in FIG. 24 (c).

In the present embodiment, when the movable lid portion 134 is closed, the small protrusion 199 of the engaging piece 149 engages with the portion of the leaf spring 185 above the corner portion 188 as shown in FIG. 23A. However, the movable lid 134 is stable in the closed posture.
When opening the movable lid portion 134, the knob portion 147 of the movable lid portion 134 is pressed. As a result, the movable lid portion 134 swings around the shaft piece 197. At this time, the small protrusion 199 of the engaging piece 149 that was engaged with the corner portion 188 of the leaf spring 185 is caused by the swing of the movable lid portion 134, and the small protrusion 199 resists the elastic force of the leaf spring 185. Moving. Then, as shown in FIG. 23B, the small protrusion 199 of the engaging piece 149 gets over the corner portion 188 of the leaf spring 185, and the movable lid portion 134 stabilizes in the open posture.

In the embodiment described above, the closed-type drug container 2,170 is mainly used, the drug container 2,170 is inserted from the door 130 provided in the housing 101, and the drug container 2,170 is moved. Although the example of moving by the means 110 has been described, the drug containers 2, 170 may be manually carried into the housing 101.
In particular, when the drug container 81 with an open drug inlet as shown in FIG. 17 is adopted, the drug container 81 is manually carried into the housing 101 and installed in a desired container mounting device 3. Further, in the present embodiment, a plurality of container mounting devices 3 are provided in the housing 101, and each container mounting device 3 is provided with a notification member 19 (FIGS. 10 and 20). The notification member 19 notifies that the container mounting device 3 on which the drug container 2 should be mounted is.
When using the drug container 81 with an open drug inlet, either the manual carry-in door 180a or 180b is opened to insert the drug container 81 into the housing 101. At that time, either container is used. The notification member 19 of the mounting device 3 lights up to notify the container mounting device 3 on which the drug container 81 should be installed.

This will be described below.
The drug container 81 with an open drug inlet is used when packaging a drug that is relatively infrequently used. More specifically, it is used when there is no container storage device 106 of the drug dispensing device 100 or the closed type drug containers 2, 170 stored outside, which are filled with the prescribed drug.
In such a situation, "Please put a hand-sprayed cassette (meaning a drug container 81 with an open drug inlet)" or "A missing cassette has occurred. A hand-sprayed cassette has occurred. In this case, install it in the feeder (meaning container mounting device 3). ”A message prompting the user to work is displayed.
Then, on the touch pal or the like of the operation display unit (not shown), the display of "opening", "closing", and "starting distribution" of the hand-spraying door A (meaning the door portion 180a for manual loading) appears.

At the same time, the notification member 19 of any of the container mounting devices 3 lights up. When the operator presses "open" on the touch panel or the like, the manual loading door 180a is automatically opened by the power of the motor.
That is, the manual loading door 180a located closest to the lit container mounting device 3 opens. The operator manually inserts the drug container 81 having an open drug inlet from the manual carry-in door 180a, and places the drug container 81 on the lit container mounting device 3.
At this time, an information reading operation for reading the information stored in the information recording member 90 such as RFID of the drug container 81 is performed, and it is confirmed whether or not the drug container 81 to be used is correctly mounted on the container mounting device 3. Confirmation operation is performed.
Then, when the operator presses "Distribution start" on the touch panel, the manual carry-in door portion 180a is closed by power.
When it is confirmed that the drug container 81 is correctly placed on the container placing device 3, the message display on the operation display unit ends. Further, the notification member 19 is turned off.

In the present embodiment, since the notification member 19 uses lamps of a plurality of colors, various messages are sent to the user depending on the change in color and the change in the way of shining (whether it is continuously lit or blinking). I can tell.
In principle, when the drug container 81 (weight when calibration or verification is performed) is requested to be placed, the notification member 19 displays a blinking display of a specific color. For example, the green lamp flashes.

When some work is being performed, it will be continuously lit in a specific color. For example, a green lamp lights up continuously. For example, when the drug is discharged from the drug container 81, the green lamp lights continuously. In addition, the green lamp is continuously lit even when the product is discharged from the normal drug container 2, is calibrated or verified by the weight, or the vibration frequency of the shaking table 50 is tuned.

When the work is completed, it will be continuously lit in a specific color. For example, a blue lamp lights up continuously. For example, when the discharge of the drug from the drug containers 2 and 81 is completed, the calibration with the weight is completed, or the tuning of the vibration frequency is completed, the blue lamp is continuously lit. When the drug is distributed using the drug container 81 with an open drug inlet, the green lamp lights continuously, and when the distribution work is completed, the color of the lamp changes to blue. The operator sees the display and knows that the work has been completed, and removes the drug container 81 from the container mounting device 3.

If any error occurs, it will be continuously lit in a specific color. For example, the red lamp lights up continuously. For example, if a weight is placed on the container mounting device 3 and calibration is performed, but the calibration fails, the red lamp lights continuously.

Next, the recommended control method will be described.
A configuration is recommended in which the vibration pattern of the shaking table 50 can be changed according to the drug type, discharge timing, and total discharge amount.
The particle size and hygroscopicity of the chemicals vary depending on the type. Therefore, when the shaking table 50 is vibrated, the behavior of the drug in the drug container 2 differs depending on the drug.
There are chemicals that are easily rectified and flow when subjected to vibration, and chemicals that are difficult to rectify. The amount of movement in one vibration differs depending on the type of drug.
In addition, there is a problem that the amount of drug discharged is not stable at the initial stage of drug discharge.

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

Then, an appropriate vibration level is selected according to the "flow coefficient" and "emission amount". The vibration level distinguishes between the vibration level at the initial stage of discharge and the vibration level at the stable period.
For example, if the drug is easily discharged such as "flow coefficient 1" and the total discharge amount is small such as "discharge amount 20", vibration is started with a slow vibration such as vibration level 3. After a certain period of time, the vibration is switched to a stronger vibration such as vibration level 10. Alternatively, the system is switched to a method in which the vibration intensity of the shaking table 50 is feedback-controlled so that the discharge amount h per unit time becomes constant, centering on a strong vibration such as a vibration level 10.

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

Further, when the amount of the drug stored in the drug container 2 is small, it is desirable to increase the vibration level until the drug reaches the drug discharging portion 13 at the tip.
That is, in the present embodiment, the drug container 2 is stored in the container storage device 106 in a vertical position. Therefore, at the time of storage, the medicines are gathered at a position far from the medicine discharge unit 13.
Further, in the present embodiment, immediately before the drug container 2 is installed in the container mounting device 3, the drug container 2 is tilted once so that the drug discharge portion 13 side of the drug container 2 faces upward as shown in FIG. 26. By this operation, the medicine in the medicine container 2 is brought to a position far from the medicine discharge part 13.

Here, if the amount of the drug stored in the drug container 2 is small, the drug inside is located at a position far from the drug discharge unit 13 immediately after the drug container 2 is placed on the container mounting device 3. It will be unevenly distributed in.
Then, the shaking table 50 is vibrated to move the drug to the drug discharge unit 13 side in the drug container 2, but when the amount of the drug stored in the drug container 2 is small, the drug unevenly distributed in the back discharges the drug. It takes time to reach the part 13.

In the present embodiment, as a countermeasure against this, a configuration is adopted in which the vibration level is strengthened until the drug reaches the drug discharging portion 13 at the tip. Further, by monitoring the weight of the drug container 2, it is determined whether or not the drug has reached the drug discharging unit 13.
More specifically, in the initial stage of starting vibration, the shaking table 50 is vibrated with a vibration stronger than the initial value determined by the flow coefficient or the like described above. Then, the weight of the drug container 2 is monitored, and if it is detected that the weight of the drug container 2 is reduced even slightly, it is determined that the drug has reached the drug discharge unit 13.
After that, the vibration is weakened, and the shaking table 50 is vibrated at the initial value determined by the flow coefficient and the like described above.
Further, when it is detected that the weight of the drug container 2 has decreased by a certain amount, the vibration of the shaking table 50 is switched to a stronger vibration.

For example, immediately after the start of vibration, the shaking table 50 is vibrated with a strong vibration such as a vibration level 12. Then, for example, when a very small amount of the drug such as 0.3 g is discharged, the vibration level is lowered to the vibration level 3 described above. Then, when a certain amount of the drug is discharged, the vibration is switched to a stronger vibration such as a vibration level 10. Alternatively, the system is switched to a method in which the vibration intensity of the shaking table 50 is feedback-controlled so that the discharge amount h per unit time becomes constant, centering on a strong vibration such as a vibration level 10.

In this way, it is desirable that the timing of switching from the initial value such as the vibration level 3 to the normal value such as the vibration level 10 is based on the amount of the drug discharged.
For example, when the shaking table 50 is vibrated by a strong vibration such as a vibration level 12 and a very small amount of a drug such as 0.3 g is discharged, the vibration level is lowered to the above-mentioned vibration level 3 and the drug is reduced to, for example, 0. When 0.8 grams are discharged, the vibration is switched to a stronger vibration such as vibration level 10. Alternatively, the system is switched to a method in which the vibration intensity of the shaking table 50 is feedback-controlled so that the discharge amount h per unit time becomes constant, centering on a strong vibration such as a vibration level 10.
The timing for switching from the initial value such as the vibration level 3 to the normal value such as the vibration level 10 may be based on time.

The above-mentioned control method is recommended when the amount of the drug stored in the drug container 2 is small, but it may be carried out regardless of the remaining amount of the drug stored in the drug container 2.

Further, when the amount of the drug stored in the drug container 2 is always small, such as a drug having a small prescription amount at one time, it is also effective to raise the drug container 2 to the bottom.
For example, as shown in FIG. 25, a partition plate (raised bottom member) 150 is provided in the drug container 2 to intentionally narrow the space of the drug container 2.
As a result, the distance between the substantially innermost portion (bottom raised bottom member 150) of the drug container 2 and the drug discharging section 13 is shortened, and the drug reaches the drug discharging section 13 at an early stage.

The drug container 151 shown in FIG. 25 has a container body 5 which is substantially entirely covered and has an internal space 155, and is deeper than the drug discharge unit 13 based on the posture of being placed on the container mounting device 3. A partition plate (raised bottom member) 150 is provided at a position on the side.
Therefore, even in the vertical posture of the drug container 151, the drug inside does not reach deeper than the partition plate (raised bottom member) 150.
In the drug container 151 shown in FIG. 25, an opening 152 is provided on the wall surface corresponding to the bottom in the vertical posture, and a rod or the like is inserted through the opening 152 to push the partition plate (raised bottom member) 150 to partition. The position of the plate (raised bottom member) 150 can be changed. Further, by providing the partition plate (raised bottom member) 150, a substantial space can be narrowed, and the effect of reducing the risk of the chemicals becoming damp is expected even when a small amount of the chemicals is stored in the chemical container 151. it can.

Next, another modification of the drug container will be described with reference to FIGS. 27 to 33. The drug container described below is a drug container 300 having an open drug inlet.
As shown in FIG. 30, the drug container 300 is composed of a storage space forming member 301 and a bottom forming member 302.
The storage space forming member 301 has a main body portion 303 whose four side surfaces are completely covered by the side wall 304 and whose upper and lower surfaces are open.
That is, the main body 303 has a rectangular plan view. The main body 303 has an opening 305 at the upper part, and the drug can be injected through the opening 305.
Further, the bottom of the main body 303 also has an opening 306 as shown in FIG. 29.
The lower opening 306 is smaller than the upper opening 305. And both are connected by an inclined side wall 304.
An information recording member 90 such as RFID is attached to the side wall 304 of the main body 303. In the present embodiment, the information recording member 90 stores a symbol or the like that identifies the drug container 300.

Guide pieces 309 are provided on the pair of side surfaces of the main body 303. The guide piece 309 is located on the side wall 304 on the long side side of the main body 303, and projects horizontally (based on the posture mounted on the container mounting device 3) from the side wall 304. Further, the guide piece 309 extends along the long side of the side wall 304. A stopper 307 is formed at one end. The stopper 307 is located at the end of the guide piece 309 and has a large cross section.
A lid 308 is attached to the opening 305 at the top of the main body 303.

The bottom forming member 302 is a steel plate having the same cross-sectional shape as the fixing iron plate portion 6 described above and containing a magnetic material component such as ferrite.
As shown in FIGS. 29 and 30, both sides of the bottom forming member 302 are bent upward around the bottom 310 to form an inclined wall 311.
Further, one end of the bottom forming member 302 in the longitudinal direction is open to form the drug discharging portion 315. A vertical wall 316 is provided on the other end side of the bottom forming member 302 in the longitudinal direction and is closed.
A plurality of protrusions 325 are provided in the region of the bottom portion 310 of the bottom portion forming member 302 near the drug discharging portion 315.
The total length of the bottom forming member 302 is longer than the total length of the storage space forming member 301 as shown in FIG. 27.

A guide receiving member 313 is provided on the outer peripheral portion of the inclined wall 311 of the bottom forming member 302.
As shown in FIG. 31, the guide receiving member 313 is composed of a receiving portion forming member 317 and an elastic member (elastic body) 320.
The guide receiving member 313 has a substantially rectangular parallelepiped box shape. The top surface portion of the guide receiving member 313 has a cover portion 318, and a slit portion 319 with which the guide piece 309 is engaged is formed between the top surface portion of the box-shaped portion and the cover portion 318.
The drug discharge portion 315 side of the slit portion 319 is opened, and the vertical wall 316 side is closed.

Inside the guide receiving member 313, two pins 324 hanging from the ceiling are provided.

The elastic member 320 is provided on the inclined wall 311 of the bottom forming member 302, and is attached to a support base 321 projecting outward in a shelf shape.
That is, it is provided on the inclined wall 311 of the bottom forming member 302, and there is a support base 321 on the outer peripheral portion thereof, and two elastic members 320 are erected from the support base 321.
Specifically, the elastic member 320 is a spring. A receiving member 322 is provided on the upper portion of the elastic member 320. A recess 323 is formed in the receiving member 322.

The receiving portion forming member 317 covers the elastic member 320, and the internal pin 324 is engaged with the recess 323 of the elastic member 320.

Further, the storage space forming member 301 described above is attached to the bottom forming member 302 via the guide receiving member 313.
That is, the guide piece 309 of the storage space forming member 301 is engaged with the slit portion 319 of the guide receiving member 313, and both are integrated.
Since the guide receiving member 313 has the elastic member 320, the storage space forming member 301 and the bottom forming member 302 are connected with the elastic member 320 interposed therebetween.
As described above, since the drug discharge section 315 side of the slit portion 319 is open and the vertical wall 316 side is closed, the storage space forming member 301 is placed along the longitudinal direction of the bottom forming member 302. By moving it to the side, the storage space forming member 301 can be removed from the bottom forming member 302.

The lower opening 306 of the storage space forming member 301 is not in contact with the bottom 310 of the bottom forming member 302, and there is a gap between the two.

The drug container 300 of the present embodiment can be used in the same manner as the drug container 81 of the drug inlet open type described above. That is, the drug is charged into the storage space forming member 301, the drug container 300 is manually carried into the housing 101, and the drug container 300 is installed in the desired container mounting device 3.
Then, the shaking table 50 of the container mounting device 3 is vibrated to discharge the drug from the drug discharging unit 315. Here, since the drug container 300 of the present embodiment has the elastic member 320 between the storage space forming member 301 and the bottom forming member 302, the bottom forming member 302 of the drug container 300 vibrates to move the drug. The vibration amount of the storage space forming member 301 is smaller than that of the bottom forming member 302.
Therefore, the detection accuracy of the storage space forming member 301 and the weight measuring means 55 is high. In addition, the movement of the drug is smooth.
That is, according to the embodiment, there is an elastic member 320 between the storage space forming member 301 and the bottom forming member 302, and the structure is such that the two are cut off. Therefore, the bottom forming member 302 directly receives the vibration from the shaking table 50 and vibrates greatly, but the storage space forming member 301 placed on the upper side vibrates less. As described above, in the present embodiment, the vibration of the storage space forming member 301 and the vibration of the bottom forming member 302 are not synchronized.
Therefore, the drug in the storage space forming member 301 falls from the opening 306 on the lower side to the bottom forming member 302, smoothly moves through the bottom forming member 302, and is discharged from the drug discharging section 315 at the tip.

In the drug feeder 1 and the drug dispensing device 100 of the present embodiment, the drug to be discharged to the distribution dish 116 or the like on the downstream side is weighed by the weight measuring means 55 built in the drug feeder 1, but an external measuring device is exceptional. In some cases, the drug is weighed in, filled in a drug container after weighing, and distributed by a powder distribution device.
In such a case, the drug container 300 is placed on a desk, and the weighed drug is charged into the storage space forming member 301.

Here, the drug container 300 described above has a bottom forming member 302 at the bottom, but the cross-sectional shape of the bottom forming member 302 is groove-shaped, and the area of the portion in contact with the desktop surface is small. Therefore, if the drug container 300 is placed directly on the desk, it is unstable and there is a concern that the drug container 300 may be turned over.

As a means for solving this problem, the drug dispensing device 100 of the present embodiment is provided with a temporary storage table 340 for temporarily placing the drug container.
The temporary storage table 340 is a table having an installation groove 341 in which the bottom surfaces of the bottom forming member 302 of the drug container 300 match.
The installation groove 341 is provided with an open portion 345 on one side and a vertical wall portion 342 on the other side.
Further, the installation groove 341 is slightly inclined so that the open portion 345 side faces upward. The inclination angle is about 3 to 10 degrees, and in this embodiment, it is 5 degrees.
In the present embodiment, the information reading device 346 is provided on the vertical wall portion 342.

In the present embodiment, the drug container 300 can be placed on the temporary storage table 340 to stabilize it, and the drug can be charged through the opening 305 of the main body 303. More specifically, the inclined wall 311 of the bottom forming member 302 of the drug container 300 is made to match the inclined surface of the installation groove 341 of the temporary standing 340, and the vertical wall 316 of the bottom forming member 302 is the vertical wall of the temporary placing 340. The drug container 300 is placed on the temporary storage table 340 in a posture of being in contact with the portion 342.
As a result, in the drug container 300, the bottom forming member 302 is in an inclined posture, and the drug discharging section 315 faces upward. Therefore, the drug does not spill from the drug discharging unit 315.
Further, the information identifying the drug container 300 is read by the information reading device 346.

In the embodiment described above, the rectifying unit 20 is provided in the drug container 2, and the rectifying unit 20 has a fixed rectifying coil 25 and a movable rectifying coil 26 as main constituent members.
However, when filling a chemical having poor fluidity such as rhubarb powder, the fixed rectifying coil 25 and the movable rectifying coil 26 are rather obstructive. Therefore, when filling a drug with poor fluidity such as rhubarb powder, it is desirable to use a drug container with the coil removed.

34, 35, and 36 show a lid member 156 attached to the drug container of the modified example.
The lid member 156 is different from the lid member 8 shown in FIGS. 5, 6 and 9 described above in that it does not have the fixed rectifying coil 25 and the movable rectifying coil 26.
Further, in the lid member 8 shown in FIGS. 6, 9, and 19, an opening 43 was provided in the central portion of the eaves lid 35, but the lid member 156 shown in FIGS. 34, 35, and 36 has this opening. There is no.
Further, the lid member 8 shown in FIGS. 5, 6 and 9 was provided with the tip closing wall 33, but the lid member 156 shown in FIGS. 34, 35 and 36 did not have the tip closing wall 33. The part is open.

In the lid member 156 shown in FIGS. 34, 35, and 36, a height limiting member 157 is provided in place of the movable rectifying coil 26.
The height limiting member 157 is a partition that limits the amount of the drug introduced into the lid member 156, and is mounted on the movable coil holding wall 32.

As shown in FIG. 35, the height limiting member 157 is a member having a groove shape in a plan view, has a partition wall 158 in the center, and has mounting pieces 159 on both sides thereof.
The mounting piece 159 of the height limiting member 157 is in contact with the movable coil holding wall 32. The upper side of the partition wall 158 is in contact with the eaves lid 35. There is a gap between the lower side of the partition wall 158 and the bottom 46 of the container body 5.
When the drug passes through this gap, the waves of the height of the drug are acclimated so that the heights are uniformly aligned and the amount of the drug discharged is optimized. Then, the drug is appropriately guided by receiving the vibration and proceeds to the drug discharging unit 13 side.

As another measure when a drug having poor fluidity is used, a method of improving the bottom 46 of the container body 5 of the drug container 2 to improve the slip of the drug can be considered.
For example, as shown in FIGS. 37 and 38, the sliding plate 250 is attached to the bottom 46 of the container body 5. The sliding plate 250 is made by bending a metal plate such as stainless steel or aluminum.
The sliding plate 250 has a shape that follows the shape of the bottom 46 of the container body 5.
Specifically, the sliding plate 250 has a groove-like cross-sectional shape, and has a bottom matching portion 251 that matches the shape of the bottom 46 of the container body 5 and a side surface 252 of the container body 5 that matches the vicinity of the bottom 46. It has a side surface matching portion 253. The side mating portion 253 is longer than the bottom mating portion 251.
Further, the sliding plate 250 is shorter than the total length of the container body 5, and is mounted near the opening of the container body 5.

In the present embodiment, the sliding plate 250 is made of a metal plate surface-treated so as to improve non-adhesiveness. For example, a material subjected to surface treatment in which nickel and fluororesin are co-deposited with iron, stainless steel, or an aluminum alloy is suitable as a material for the sliding plate 250.
It is desirable that a non-adhesive resin (for example, fluororesin) having a volume ratio of about 30% is uniformly distributed on the surface film.

The material of the sliding plate 250 is not limited, and a resin itself having excellent non-adhesiveness such as fluororesin may be used as the material. The shape of the sliding plate 250 is not limited, but it is desirable that the bottom portion 46 of the container body 5 covers the vicinity of the opening of the container body 5.
The reason for this is that the vicinity of the opening of the container body 5 is a portion that protrudes from the shaking table 50 of the container mounting device 3, for example, as shown in FIG. This is because there is a concern that it will be somewhat worse than the site.
It is desirable that the sliding plate 250 covers a wider area of the bottom 46 of the container body 5. Specifically, the sliding plate 250 may completely cover the bottom 46 of the container body 5. For example, it is made by bending a metal plate surface-treated with fluororesin into a groove shape, and has an outer shape that follows the shape of the bottom 46 of the container body 5, and the total length thereof is the bottom of the container body 5. A sliding plate equivalent to the total length of 46 may be adopted.
Further, instead of the sliding plate 250, the inner surface of the container body 5 may be coated with a resin having excellent non-adhesiveness.

In the drug feeder 1 of the embodiment described above, the container mounting device 3 includes a shaking table 50, a vibrating means 51 for vibrating the shaking table 50, and a container holding means (magnet member) for fixing the drug container 2 to the shaking table 50. 62) and a weight measuring means 55 for directly or indirectly measuring the weight of the drug container 2, the drug container 2 is placed on the shaking table 50, and the drug container 2 is placed on the shaking table 50 by the container holding means. It is possible to discharge the drug little by little from the drug container 2 by vibrating the shaking table 50 and detect the discharge amount of the drug by the weight measuring means 55, and the total amount of the drug discharged from the drug container 2. The drug feeder 1 is characterized in that the vibration of the shaking table 50 becomes smaller as the amount approaches the target amount.

In the drug feeder 1 of the embodiment described above, the container mounting device 3 includes a shaking table 50, a vibrating means 51 for vibrating the shaking table 50, a container holding means for fixing the drug container 2 to the shaking table 50, and a drug. It has a weight measuring means 55 for directly or indirectly measuring the weight of the container 2, the drug container 2 is placed on the shaking table 50, the drug container 2 is fixed to the shaking table 50 by the container holding means, and vibration is performed. It is possible to vibrate the table 50 to discharge the drug from the drug container 2 little by little, and to detect the discharge amount of the drug by the weight measuring means 55, and the total amount of the drug discharged from the drug container 2 is less than the target amount. The drug feeder 1 is characterized in that the vibration of the shaking table 50 becomes large when the amount of the drug discharged per unit time is less than a certain amount.

The drug feeder 1 of the embodiment described above stores the total discharge amount up to the present and vibrates when the discharge amount of the drug per unit time is a certain amount or less even if the vibration of the shaking table 50 becomes large. It has a configuration in which the vibration of the table 50 is stopped and the drug container 2 is removed from the shaking table.

When the drug container 2 is fixed to the shaking table 50 again, the drug feeder 1 of the embodiment described above restarts the vibration of the shaking table 50, discharges the drug from the drug container 2 little by little, and discharges the drug from the drug container 2 little by little. It has a configuration in which the vibration of the shaking table 50 is stopped when the total amount of the discharged chemicals reaches the target amount.

In the embodiment described above, only one electric wire holding member 73 is provided, but a plurality of electric wire holding members 73 may be provided. FIG. 18 shows an example in which two electric wire holding members 73 are provided.

Further, in the above-described embodiment, the top surface of the desiccant insertion portion 15 and the upper portion of the fixed rectifying coil 25 of the coil accommodating space 28 are closed by the inner lid 22, and the upper portion of the movable rectifying coil 26 of the coil accommodating space 28 is covered. Although it is closed by the lid (eaves member) 35, as shown in FIG. 19, the rear end side of the lid main body 10 may be closed by the entire lid 23 in which both are integrated.

In the above-described embodiment, the one using magnetism as the container holding means is disclosed, but another actuator such as a motor may be used as the container holding means.

In the above-described embodiment, the control using a coefficient called "flow coefficient" has been introduced, but the "flow coefficient" will be additionally described below.
In the drug feeder 1 of the above-described embodiment, the frequency (frequency) per unit time of the shaking table 50 and the magnitude of the amplitude can be changed, and the frequency and the frequency can be changed according to the drug type, the discharge time, and the total discharge amount. It is possible to change the magnitude of the amplitude.

More specifically, the shaking table 50 of the present embodiment has a structure in which the magnitude of vibration can be changed according to a preset value (a structure in which the frequency and amplitude of vibration can be changed). ). Then, a "flow coefficient" is assigned according to a target set value (hereinafter, also referred to as a vibration value) when operating the shaking table 50 when discharging each chemical.
In the above embodiment, it is divided into three stages from "flow coefficient 1" to "flow coefficient 3", but more preferably, it is divided into nine stages from "flow coefficient 1" to "flow coefficient 9".

Specifically explaining this "flow coefficient", this "flow coefficient" is a value set for each drug feeder 1 to be shipped, and the drug feeder 1 is actually used to determine the ease of discharging the drug in advance. It is a value assigned after experimentation. Specifically, first, a reference chemical (for example, magnesium oxide) is used, a vibration value for paying out a predetermined amount in a predetermined time is acquired, and the vibration value is classified into “flow coefficient 1”. Then, for each chemical, a vibration value for delivering the same amount as the reference chemical in the same time is acquired, and a "flow coefficient" is assigned according to the vibration value. It should be noted that the larger the value of the flow coefficient, the larger the vibration of the shaking table portion.
In other words, the "flow coefficient" is a set value of vibration that is the target for discharging each chemical in the same way as the reference chemical, and the larger the value of the "flow coefficient", the more difficult the chemical to flow. Therefore, it is also a value indicating the ease of discharging chemicals.

Then, an appropriate vibration level is selected according to the "flow coefficient" and "emission amount". Further, the vibration level distinguishes the vibration level at the initial stage of discharge from the vibration level at the stable period. For example, it is a chemical that is easily discharged such as "flow coefficient 1" and is total like "discharge amount 20". When the amount of discharge is small, vibration is started with a slow vibration such as vibration level 3, and when a certain amount of decrease in chemicals is detected (when a certain weighing value is reached), the vibration level is increased to 10. Switch to vibration. Alternatively, the system is switched to a method in which the vibration intensity of the shaking table portion is feedback-controlled so that the discharge amount h per unit time becomes constant, centering on a strong vibration such as a vibration level 10.

In the embodiment described above, the drug feeder 1 is used to supply the powder to the distribution dish 116 of the drug division region (powder distribution device) 103, but the drug feeder 1 directly supplies the powder to the drug packaging device 122. May be good.
It is also conceivable to supply tablets and capsules using the drug feeders 1, 50 of the present invention.

One aspect of the present invention developed to solve the above problems is a drug container and a drug feeder having a container mounting device, and the drug container is removable from the container mounting device. The drug container has a drug discharge section for discharging the drug, and the container mounting device includes a shaking table, a vibrating means for vibrating the shaking table, and a container holding for temporarily fixing the drug container to the shaking table. It has means and a weight measuring means for directly or indirectly measuring the weight of the drug container, the drug container is placed on a shaking table, the drug container is fixed to the shaking table by the container holding means, and the shaking table is set.
