DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for dispensing a prescribed powdered medicine in individual doses, and then dispensing the powdered medicine, scraping it out with a scraping device, dividing the powdered medicine, and packaging the same.

[0002]

2. Description of the Related Art In the conventional powder dispensing apparatus, the scraping direction of a scraping device is scraped in an outer circumferential direction with respect to the rotation axis of the dispensing device, and the powder medicine scraped by the scraping device is defined as an angle at which the powder can be put into a packaging hopper. In order to keep the height of the R-shaped concave portion and the outer diameter edge of the distribution dish low, the rake angle was formed around 23 degrees, and the disk diameter of the scraping device was 110 mm.

[0003] For this reason, when powder is deposited on the distribution dish, the diameter of the distribution dish is set to 500 so that the powder deposited from the R-shaped recess is not blown off by the rotational centrifugal force of the distribution dish.
If the powder is not pressed and rotated around 30 rotations per minute, powders such as granules will be scattered by centrifugal force during dispensing.

[0004] In the powder dividing and packaging apparatus, the accuracy of powder dividing is required.
It is desirable to rotate the dispensing dish as fast as possible and feed it from the powder feeder to the dispensing dish.
Japanese Patent Application Laid-Open No. 57-86401 discloses the technique.

The technique disclosed in Japanese Patent Application Laid-Open No. 57-86401 discloses a method in which a powder is deposited from a powder feeder on a V-shaped annular basin, and then the powder is supplied.

There is disclosed a technology related to a dispensing / supplying device that dispenses powdered medicine by rotating the dispensing dish at a predetermined angle as a rotation center direction of the powdered medicine dispensing dish whose direction is drawn out in a donut shape.

Conventionally, along with the downsizing of the machine, the scraping mechanism and the packaging hopper are installed on the outer periphery of the R distribution tray 5, which hinders the downsizing of the machine.

[0009]

SUMMARY OF THE INVENTION Incidentally, Japanese Patent Application Laid-Open No. 8-85
In order to manufacture a powder dispensing dish such as disclosed in 502 at a low price, it is desirable to press the powder dispensing dish, and because it comes in contact with the powder, stainless steel is used to maintain durability and cleanliness. Is desirable.

The powder dispensing dish is required to have a high degree of accuracy. In particular, the axis of the R-shaped concave portion diameter of the powder dispensing dish, the accuracy of the rotation axis when the powder dispensing dish is rotated, and the accuracy of the powder dispensing dish are improved. There is a demand for run-out of the rotating shaft, noise and low vibration, and bending and twisting of the powder dispensing dish.

Further, when the R distribution dish is rotated at a high speed, a part of the powder scattered during the distribution from the feeder is blown off by a rotary centrifugal force, and the blown powder comes into contact with the rotary support ring and the rotary support ring. These problems do not occur because powders such as granules are caught in the contacting parts of the rollers that generate noise, sudden noise is generated, and the R distribution dish is rattled, and durability is reduced when used in such a state. Is required.

[0012] Another problem is the problem of making the machine compact.

According to the present invention, the powder dispensing plate is kept inexpensive, and the powder dispensing plate is maintained in a shape capable of being pressed and maintaining high accuracy. Accuracy of the rotation axis when rotating the powder dispensing dish and the axis of the R-shaped recessed part diameter, or vibration of the rotating axis of the powder dispensing dish, or noise and vibration reduction when the powder dispensing dish is rotated at high speed With respect to the required accuracy such as, it is possible to easily assemble and adjust, and some of the powder that scatters during distribution from the feeder is blown away by a rotary centrifugal force, and the rotary support ring and the rotary support ring The purpose of the present invention is to solve problems such as a problem that occurs when a roller comes into contact with a contact portion of a roller.

[0014]

According to the present invention, in order to solve the above-mentioned problems, the outer peripheral edge of the R-shaped recess is formed to be higher than the height of the inner peripheral edge of the R-shaped recess. The flange portion was formed integrally with the outside of the outer peripheral side edge of the depression portion by press molding, and the flange portion of the powdered medicine dispensing plate was rotatably supported.

[0015] This makes it possible to manufacture a dispensing dish in which the powder dispensing dish can be rotated at a high speed while maintaining high precision by press working at a low price.

Further, a flange provided outside the outer peripheral side edge of the R-shaped recessed portion and a lowermost point of the R-shaped recessed portion of the powdered medicine dispensing dish are concentric with the rotating shaft rotated by supporting the rotating support ring. So that the rotation support ring of the powdered medicine dispensing plate is rotatably supported.

Thus, when the powder dispensing plate is actually rotated, the accuracy of the rotation axis when the powder dispensing plate is rotated and the accuracy of the rotation axis when the powder dispensing plate is rotated and the powder dispensing To solve the problems such as easy assembling and adjustment of required accuracy such as vibration of the rotating shaft of the plate or reduction of noise and vibration when the powder dispensing plate is rotated at high speed. Can be.

[0018] Further, the powder support such as granules scattered by the centrifugal force of the R distribution tray during dispensing is disposed at a position where the powder such as granules scattered by the centrifugal force of the R distribution tray is not caught in the rotating support ring of the powder distribution tray and the contact portion of the roller contacting the rotation support ring. did.

Thus, during the distribution of powder from the feeder,
Even if the R distribution dish 5 is rotated at a speed of about 60 rotations per minute, powders such as granules scattered by the centrifugal force of the R distribution dish do not bite into the contact portion of the roller that comes into contact with the rotation support ring. And rattling of rotation can be prevented.

[0020]

Embodiments of the present invention will be described below.

FIG. 1 shows an example of a powder dividing and packaging apparatus according to the present invention.
Is activated, and at the same time, the powder is supplied to the R distribution dish from the tip of the trough 3 while the R distribution dish 5 is rotated at a speed of about 60 rotations per minute.

The vibrating feeder is constructed as shown in FIG. 2 and the feeder 1 is driven at a frequency of about 100 Hz by two piezoelectric elements 4 fixed below the trough 3 so that the feeder 1 is driven on the support plate 20 below the chute. The vibration sensor 21 is mounted in parallel with the vibration direction of the piezoelectric element 4, the lower part of the piezoelectric element 4 is fixed to a fixed base 22, and the fixed base absorbs the vibration of the feeder by a spring 23. Attached to.

FIG. 3 shows a hopper angle support device. A loading hopper 2 is supported above a trough 3 by a support member 24 of the hopper angle support device. The support member is configured to rotate up and down, and an arm member 2 for raising and lowering the support member
6 connects the support member 24 and a crankshaft rotated by a motor 27, and when the crankshaft is rotated by the motor 27, the opening angle of the input hopper can be changed.

The motor 27 employs a stepping motor, and can stop and hold the charging hopper at a position corresponding to a target opening angle. When the supply of the powder is completed, the powder attached to the surface of the charging hopper is removed from the motor 2.
7 is controlled at a fine angle (about 15 range) to vibrate the hopper, and the attached powder is dropped into the trough. Further, the powdered medicine adhered by hitting the charging hopper with the solenoid member may be dropped into the trough.

It is preferable that a dust collecting device 28 shown in FIGS. 4A and 4B is provided near the input port of the input hopper 2 of the feeder 1.

Since the dust collecting device 28 is formed of a cylindrical frame larger than the outer peripheral portion of the hopper inlet, and is rotatably supported by the support pipe 29, as shown in FIG. It is provided so as to be separated from the charging hopper.

A dust collecting port 30 is provided on the inner periphery of the cylindrical frame of the dust collecting apparatus 28, and the chemical dust generated when the powdered medicine is put into the hopper is sucked from the dust collecting port 30 to the dust collecting apparatus. It has become so.

The path of the dust collector is as shown in FIG.
The cleaner device 40 includes a filter 41 and a fan 42, and is connected to a switching valve 43.

The powder dust sucked from the dust collecting port 30 of the dust collecting apparatus 28 is connected to the switching valve 43 through the support pipe 29, and is sucked from the dust collecting port 30 of the dust collecting apparatus 28 by the flow rate adjusting device 44 on the way. Adjust the flow rate.

In addition, a unit connected to the switching valve 43 is provided with a cleaner 45 with a rotary brush for cleaning the surface of the R distribution dish and a vacuum cleaner 46, but their explanation is omitted.

The R distribution dish 5 shown in FIG. 1 is formed by press working, and the inner peripheral side of the R-shaped recessed portion is opened in a donut shape, and the angle of curvature of R is about 23.5 degrees. An inner peripheral side edge 5a is formed.

On the other hand, the outer peripheral edge 5c of the lowermost point 5b of the R-shaped recessed portion is set to have a curvature angle of R of about 50 degrees, and the outer peripheral edge 5c is larger than the height of the inner peripheral edge 5a. The warp height is set high, and the powder dispensed from the feeder 1 prevents the powder from being scattered by the centrifugal force of the R distribution dish even when the R distribution dish 5 is rotated at the above-described rotational speed. .

Outer edge 5c of lowermost point 5b of R-shaped recess
Further, a flange 5d for holding a support ring 6 for rotating the R distribution plate is formed integrally with the R distribution plate on the outer peripheral portion.

FIG. 6 is a diagram showing the arrangement of the feeders.

As shown in FIG. 7, the trough shown here has a tip portion lowered in two steps, and the tip portion of the trough 3 further has two guide grooves 3a3b.

Each of the two guide grooves 3a3b has an R
The powdered medicine, which is arranged at the inner and outer circumferences with the lowermost point 5b of the concave portion of the shape interposed therebetween and drops from the tip of the trough 3, is guided by the guiding groove 3a.
The powders that have fallen much from 3b and fall into the R distribution dish 5 from the guiding grooves 3a3b respectively bounce in the direction of the lowermost point 5b of the R-shaped dent, and the splashed powders hit each other, and the lowermost point 5b of the R-shaped dent. Is deposited at the position.

For this reason, the powdered medicine rarely scatters from the R distribution plate 5, and the trough has a two-step lower end, so that the fall height is suppressed and the trough is hard to jump.
The cross-sectional shape of the powder is high at the top of the line of the lowermost point 5b of the R-shaped concave portion, and it is difficult for the powder to accumulate.

In order to rotate the R distribution dish at a high speed as in the present invention, the trough drop opening of the feeder and the R distribution dish are made as close as possible, or the inclination of each of the inner and outer diameters sandwiching the lower point of the R distribution dish. It is necessary to devise a method of dropping the powder on the surface so that the powder does not jump from the rotating R distribution dish.

The powder dispensed in this manner is fed into the R distribution tray 5 at a predetermined angle by the scraping device 7, and the powder in the range sent in one time is scraped into the packaging hopper 8 by the scraping device. Dropping, the shutter of the packaging hopper 8 is released, and the powdered medicine is put into the wrapping paper 10, and the wrapping paper 10 is sequentially drawn in by the rotation of the sealing device 11, and is wrapped.

The scraping device 7 is retracted upward during dispensing, and when dispensing is completed, the scraping device 7 descends and comes into contact with the R distribution plate. The powder is scraped off in the inner diameter direction of the R distribution dish.

When these distribution and division operations are completed, the rotary brush-equipped cleaner 45 shown in FIG. 5 is operated to clean the surface of the R-shaped concave portion of the R distribution dish 5 and waits for the next prescription.

The operation of the scraping device 7 is performed as follows.

As shown in FIG. 8 (a), the scraping device 7 is configured to cut out the powder deposited on the R distribution tray 5 by the disk 12, and rotate the R distribution tray 5 to feed the powder to the disk 12. After that, the guide plate 13 removes the powdered medicine deposited on the R distribution dish 5 by the rotation of the scraping device 7,
A scraping plate 14 provided between the disk 12 and the guide plate 13 is used to scrape off the R distribution plate 5, and these are driven by a motor 15.

As shown in FIGS. 8B and 8C, the scraper 1
The tip of the scraper 4 moves on the inner surface of the R in accordance with the rotation of the scraping device 7 while contacting the inner surface of the R distribution dish 5, but the tip of the scraping plate 14 is positioned at the tip as shown in FIG. If you make a cut, when you separate from the R distribution dish 5,
The repulsion of the rubber material of the scraper is suppressed, and the granular powder is less likely to jump.

FIGS. 9A and 9B are side views of the scraping device.

The rotation of the disk of the scraping device does not rotate at a constant speed, but at a predetermined speed within a predetermined range.

As shown in FIG. 9B, the range of the operation during scraping is divided as follows, and the operation is stopped at the position of the inner peripheral side edge 5a of the R distribution plate 5 or decelerated to the minimum speed. Have been.

After passing through the position of the inner peripheral side edge 5a of the R distribution dish 5, the rotation speed is accelerated for a while, and the rotation axis x rotates at a substantially constant speed from a certain position, and after the end of acceleration, R
The range of the inner peripheral edge 5c of the distribution plate 5 is set as a speed adjustment section.

In this speed adjustment section, the rotation is not based on the fact that the scraping plate 14 has reached the inner peripheral edge 5c of the R distribution plate 5, but it is determined whether the tip of the guide plate 13 has reached. At this point, for example, when the split feed angle of the R distribution tray 5 is small, the split feed angle reaches the next stop point earlier than the tip of the guide plate 13 reaches the position of the R distribution tray 5c.

For this reason, it is not necessary to decelerate in the rotation axis x speed adjustment section. However, if the set number of packages is reduced, the divided feed angle of the R distribution plate 5 is correspondingly increased. When rotating at a constant speed in the speed adjustment section, the leading end of the guide plate 13 reaches the position of the R distribution plate 5c earlier than the divided feed angle reaches the next stop point, and the rotation axis x is rotated as it is. While the guide plate 13 is in contact with the powder that accumulates, the R distribution tray 5 is still fed, and the powder distribution area deposited on the R distribution tray 5 required for division can be taken in between the disc 12 and the guide plate 13. Error occurs.

For this reason, time data corresponding to the number of packages and the increase / decrease of the feed angle of the R distribution plate 5 is stored, and the time required for the leading end of the guide plate 13 to reach the position of the R distribution plate 5c is stored. If it is predicted that the rotation time is earlier than the predetermined time, the rotation speed of the rotation axis x is controlled to be reduced and rotated in the speed adjustment section.

As shown in FIG. 1, a tablet divider 16 for distributing tablets by hand is provided above the R distribution plate 5, and a tablet chute 18 having a shutter 17 for dropping into the packaging hopper 8. Are provided corresponding to the width of the splitter.

The tablet dividing machine 16 is a container arranged in a small mesh shape, and a bottom plate shutter (not shown) is provided on the bottom surface of each of the meshes.

Since the bottom plate shutter moves while contacting the bottom in the moving direction of the tablet dividing machine 16, when the bottom plate shutter of the tablet dividing machine 16 reaches the opening of the chute 18, the shutter of the tablet dividing machine 16 is naturally released, and the inside of the container is opened. The tablets are dropped on the chute 18. The opening of this chute 18 is provided with a step-like slit at a pitch obtained by dividing one cell in the transport direction of the tablet dividing machine 16 by the number of cells provided in the width direction with respect to the moving direction of the tablet dividing machine 16. Tablet dividing machine 16
Is transferred at a pitch obtained by dividing one cell in the transfer direction of the tablet dividing machine 16 by the number of cells provided in the width direction, so that the bottom plate shutter of the tablet dividing machine 16 is sequentially opened in the width direction from the front corner. I do.

The shutter 1 provided at the exit of the chute 18
Reference numeral 7 operates at a timing associated with these series of operations.

FIG. 14 is a view showing a conventional scraping mechanism, the driving of the R distribution tray, and the arrangement of the packaging hopper and the like. The rotating shaft of the elevating arm 17 for raising and lowering the disk 12 of the scraping device and the packaging hopper 8 are the R distribution tray. 5 outside,
The rotation drive of the R distribution dish 5 is driven by an R distribution dish drive motor 16. The feeder 1 is arranged outside the R distribution dish 5, and when the powdered medicine is put into the input hopper 2, the R of the R distribution dish 5 is passed through the trough 3. Supplied to the part.

In the case of the apparatus shown in FIG. 10 for scraping and packing powder in the direction of the center of the R distribution plate 5, the rotation of the R distribution plate 5 cannot be provided at the center as shown in FIG. A support ring 6 is provided on an outer peripheral portion of the distribution dish 5, and the support ring 6 is rotatably supported by a bearing 17.

The support of the R distribution dish 5 plays an important role in such a device, and if there is a problem with the rotating support means, the powder generated during the distribution may be disturbed by the vibration generated while the R distribution dish is rotating. The concentric circle of the lowermost point 5b of the R-shaped concave portion is deviated meandering or eccentrically and is distributed, or the powder concentrates on a part of the circumference, which directly affects the division accuracy.

As a technique for solving the technique related to the rotation support, the problem can be easily solved by supporting on the rotation center axis of the R distribution dish. However, as in the present invention, the powdered medicine is directed in the rotation center axis direction of the R distribution dish. In this case, the rotation of the R distribution dish is restricted at least outside the inner peripheral edge 5a of the R distribution dish, and the rotation of the R distribution dish outside the inner peripheral edge 5a of the R distribution dish is restricted. When the support is performed, it is difficult to adjust the concentricity of the rotating shaft of the R distribution dish at the time of assembling because of the relationship between the lowermost point 5b of the R-shaped recessed portion and the rotation support means. The farther away from the rotation axis in the outer peripheral direction, the more difficult it is to adjust the concentricity of the rotation axis of the R distribution dish during assembly.

Conventionally, when the R distribution dish is rotated at 30 revolutions per minute, it is possible to support the rotation support portion of the R distribution dish by moving the rotation support portion to a certain extent in the outer circumferential direction from the rotating shaft. In the case of the present invention in which the rotation is performed at 60 rotations per minute, the precision and shape of pressing the R distribution plate must be strictly determined. Yes, and if the arrangement of the bearing 17 is not devised, the scattered powder will bite between the support ring 6 and the bearing 17,
It includes conditions that generate noise that could not be considered conventionally. (Conventionally, the support of the R distribution plate has a problem that the rotation speed is low inside the drop position of the powder distribution plate, and the powder that scatters without being concerned about the arrangement of the bearings gets stuck between the support ring and the bearings. Does not occur.)

From these facts, the problem of getting stuck between the support ring 6 and the bearing 17 is that the powder disperses during distribution because the powder is concentrically located at the lowest point 5b of the R-shaped depression during distribution. Distributed meandering or eccentrically, or
Since the problem that the powder concentrates on a part of the circumference occurs, in the present invention, as shown in FIG. 7, the contact portion between the support ring 6 and the bearing 17 is formed by the flange 5d of the R distribution plate 5. Below the position, and in the radial direction substantially inward of the outer diameter of the flange 5d, at a position outside the inner peripheral side edge 5a, so that when the powdered medicine being distributed is scattered, the support ring 6 and the bearing 1
7 does not bite into the contact portion.

The contact portion of the support ring 6 with the bearing 17 is positioned below the position of the flange 5d of the R distribution plate 5 so that the flange 5d
In a case where the position is substantially in the radial direction of the outer diameter of the
When provided inside the parabolic range of powdered powder under conditions such as centrifugal force and the like, powdered drug may very rarely bite into the contact portion between the support ring 6 and the bearing 17, but this does not cause a serious problem. Even in such a case, the support ring 6
A continuous vibration can be generated by removing the powder sticking to the support ring 6 by sandwiching the contact portion with the bearing 17 with a brush or the like as shown in FIG.

However, when the contact portion of the support ring 6 with the bearing 17 is located at the same or higher position than the position of the flange 5d of the R distribution plate 5 and substantially in the radial direction of the outer diameter of the flange 5d, In the case where the powder is provided outside the range of the paraboloid of flying powder under conditions such as centrifugal force from the plate 5, the powder often gets stuck in the contact portion between the support ring 6 and the bearing 17. For example, if the contact portion between the support ring 6 and the bearing 17 is a brush member 3 as shown in FIG.
Even if the powder adhered to the support ring 6 is removed by being sandwiched by the support ring 6 or the like, the powder that cannot be removed in a short time is accumulated, and the continuous vibration is generated, which is not preferable.

FIGS. 11A, 11B, and 11C are views showing a supporting form of the support ring 6 and the bearing 17. FIG.

The support form of the support ring 6 and the bearing 17 shown in FIG. 11A includes a bearing 17 for pressing the inner diameter side of the support ring 6 downward in the outer peripheral direction, and the support ring 6 mounted on the bearing 17. The support ring 6 and the bearing 17 are supported on the rear surface side of the R distribution plate 5.

The supporting form of the support ring 6 and the bearing 17 shown in FIG. 11B includes a bearing 17 for pressing the outer diameter side of the support ring 6 downward in the inner circumferential direction, and a support ring 6 on the bearing 17. The support ring guide 6a extends upward from the outer side of the flange 5d provided on the outer peripheral portion of the R distribution plate 5 from the support ring.

For this reason, the powdered medicine scattered from the surface of the R distribution plate 5 is less likely to be scattered to the outer peripheral side of the R distribution plate 5 by the support ring guide 6a. Powder powder is rarely interposed between them.

Here, the shape of the support ring guide 6a is a support ring extending upward, but the shape of the support ring guide 6a may be a support ring guide 6a extending in the outer peripheral direction so as to cover above the bearing 17. ,
Instead of the support ring guide 6a, a flange 5d provided on the outer peripheral portion of the R distribution plate 5 may cover the bearing 17 above.

The supporting form of the support ring 6 and the bearing 17 shown in FIG. 11C is such that the bearing 17 presses the outer diameter side of the support ring 6 downward in the inner circumferential direction, and the support ring 6 is placed on the bearing 17. The gap is provided between the flange 5d and the support ring 6 on the back surface of the flange 5d provided on the outer peripheral portion of the R distribution plate 5, and the gap is used as a starting point. The cover 17 is provided so as to cover the bearing 17 and covers the periphery of the bearing 17 where the bearing 17 does not contact the support ring 6.

Since the bearing 17 is covered by the cover member 18, it is unlikely that the powdered medicine is accidentally caught between the support ring 6 and the bearing 17.

Further, the contact surface of the bearing may be made of a material such as resin, and a soft material capable of absorbing vibration may be fixed to the support ring. Conversely, the surface material of the bearing 17 may be made of resin or rubber. By using R
It is possible to cope with an increase in the speed of the distribution dish 5.

Further, if the bearing 17 has a diameter as large as possible, the rotational speed of the bearing decreases, and durability, noise and vibration can be suppressed.

It should be noted that FIGS. 8 (a) and 8 (b)
(C) is a means shown in the embodiment, in which powder such as granules scattered by the centrifugal force of the R distribution dish bites into the contact portion between the rotation support ring of the powder distribution plate and the roller contacting the rotation support ring. The expression “disposed in a position that does not exist” includes all means such as covering with a cover.

FIG. 12 shows a different type of mounting of the R distribution dish 5.

Here, the flange 5d of the R distribution plate 5 to be raised does not have a screw hole for fastening to the support ring 6,
The flange 5d of the R distribution plate 5 is bent annularly below the horizontal line.

By bending the flange 5d downward as described above, the bending strength of the R distribution plate 5 is improved as the bending angle becomes greater from the horizontal direction to the vertical direction. Difficulties arise.

However, as shown in FIG.
The problem is solved by bringing d into contact and tightening the tightening screw 19 with a countersunk screw or a fastener having a slope of the support ring and the flange 5d with the tightening screw 19.

FIG. 13 is a control block diagram of a packaging apparatus in which the present invention is used.

The reference numerals in each unit are the same as those described above, and the detailed description is omitted here.

The packaging device includes input means 3 such as a keyboard.
2, the number of divisions, operating conditions, and the like are input. The number of divisions is set based on the number of daily doses and the prescribed number of days after charging the powdered medicine based on the prescription information into the input hopper 2, and then setting the number. The operating conditions mainly mean that the supply amount of the feeder is adjusted each time the type of medicine changes, and that the setting of the packaging form and the like is performed.

The information input here is transmitted to the computer 3
3 and transmitted to the corresponding sequencer for each piece of information, and the computer 33 includes the concept between the microcomputer and the personal computer.

At the start of the packaging start, the powdered medicine put into the charging hopper 2 is supplied with the powdered medicine from the trough 3 to the R distribution dish 5 by the operation of the piezoelectric element 4 under the conditions set by the input means 32 and the R distribution dish 5. The motor 16 is rotated at a speed of 60 rotations per minute.

At the tip of the trough 3, a sensor 31 for monitoring the supply of the powder is provided.
Judgment is made without detection, cleaning of the powder adhering in the input hopper 2 in the next step, and full operation of the piezoelectric element 4 to supply the remaining medicine in the trough.

After the operation is completed, the rotation of the R distribution plate 5 is stopped, and the disk 12 of the scraping device 7 is lowered onto the R distribution plate 5.

The R distribution plate 5 is fed by the angle of the division range,
Subsequently, the drive of the scraping device 7 rotates the motor 15,
When the scraping plate 14 of the scraping device 7 is detached from the inner peripheral edge 5a, the R distribution plate 5 is fed by the angle of the next divided range, and the operation is repeated by the set number of packages.

In correspondence with this dividing operation, the heater roller 1
1a and 11b are operated, 11a seals the bag so as to divide the bag at regular intervals in the width direction, and 11b seals the bag in a cylindrical shape in the longitudinal direction.

The powdered medicine is packaged through a packaging hopper 8 provided at a position where the packaging paper is folded and spread, and a required patient name, a required time, etc. are printed on the surface of the packaging paper by a printing device 34. You.

It is also possible to operate by receiving necessary information from the host computer 35.

As described above, according to the present invention, when pressing the distribution dish, the outer diameter edge of the R-shaped depression is higher than the height of the inner peripheral edge of the R-shaped depression provided on the outer periphery of the distribution dish. In addition to being formed, a flange portion is provided outside the outer diameter edge of the R-shaped recessed portion so as to be rotatably supported.

Thus, it is possible to manufacture a dispensing dish in which the powder dispensing dish can be rotated at a high speed while maintaining high accuracy by press working at a low price.

Also, a flange provided outside the outer diameter edge of the R-shaped recessed portion, and a rotation support ring provided along the flange on a concentric axis with the rotation axis of the powdered medicine dispensing dish, and the rotation support ring is provided with the rotation support ring. The flange portion is fixed, and the rotation support ring of the powdered medicine dispensing plate is rotatably supported.

By this, when the powder dispensing plate is actually rotated, the accuracy of the rotation axis when the powder dispensing plate is rotated, the accuracy of the rotation axis when the powder dispensing plate is rotated, and the powder dispensing To solve the problems such as easy assembling and adjustment of required accuracy such as vibration of the rotating shaft of the plate or reduction of noise and vibration when the powder dispensing plate is rotated at high speed. Can be.
