Hereinafter, a powder medicine packaging device according to this embodiment will be explained using the drawings.

FIG. 1 is a perspective view showing a powder medicine packaging device according to this embodiment, and FIG. 2 is a front view showing a disk distribution section and packaging device according to this embodiment. FIG. 3 is a plan view showing the disk distribution section and packaging device according to this embodiment. As shown in FIG. 1, the powder medicine packaging device 1 according to the present embodiment includes a weighing device 10, a powder distribution disk 20, a frame 40 forming the skeleton of a casing (not shown), and a powder distribution disk 20. A powder supply device 60 is provided at the top and fixed to the frame 40, and a packaging device 70 is provided below the distribution disk 20, as shown in FIG.

In this embodiment, as shown in FIG. 2, a disk distribution section is operated by a weighing device 10, a rotation drive section 30 disposed above the weighing device 10, and a distribution disk 20 disposed above the rotation drive section 30. It consists of The weighing device 10 is fixed to a housing connecting portion 16 via a vibration absorber 14, and the housing connecting portion 16 is connected to a frame 40 as shown in FIG. Therefore, the disk distribution section is supported by the frame 40 via the housing connection section 16.

In addition, the code|symbol 80 shown in FIG. 1 is a feeder by which an operator separately supplies powder medicine to the distribution disk 20 without using the powder supply device 60, and the code|symbol 50 shown in FIG. 2 is a feeder from the distribution disk 20. This is a scraping part that scrapes out one package of powder medicine at a time. The powder scraped out by the scraping unit 50 is sent to the packaging device 70 by the falling hopper 51.

In this embodiment, two sets of the disk distribution section, scraping section 50, powder supply device 60, and feeder 80 are provided symmetrically on the left and right, and a single falling hopper 51 is positioned between the two sets of disk distribution sections. A packaging device 70 is provided below the disc distribution so that the packaging device 70 can be used.

First, the disk distribution section and packaging device 70 will be explained in detail.

As shown in FIG. 2, a base 31 of a rotary drive section 30 is fixed on the object mounting section 12 of the weighing device 10. A bearing (not shown) is fixed to the base 31, and a pulley (not shown) is rotatably provided around the bearing. A distribution disk 20 is detachably fixed to the upper part of this pulley.

A timing gear is formed on the outer periphery of the pulley, and a timing belt is stretched between the pulley and the timing gear attached to the shaft of a disk motor 32 fixed to a base 31.

With such a configuration, the weighing device 10 includes a base 31 of the rotary drive section 30 fixed to the object mounting section 12 of the weighing device 10, and a pulley provided on the base 31. , the bearing, the disc motor 32, the distribution disc 20, etc., can be measured. In other words, when no powder is supplied to the distribution disk 20, the weight of the tare of the rotational drive unit 30 and the like is measured.

Powder medicines are dropped onto the distribution disk 20 little by little from a powder supply device 60 provided on the upper part of the distribution disk 20. Since this powder supply device 60 is fixed to the frame 40, it is not subject to weight measurement by the weighing device 10. Therefore, the weighing device 10 measures the total weight of the rotary drive unit 30, the distribution disk 20, etc. fixed to the object to be measured 12, and the weight of the powder supplied to the distribution disk 20. Become. Therefore, by subtracting the weight of the tare mentioned above from the weight measured by the weighing device 10, the weight of the powder actually supplied to the distribution disk 20 can be calculated.

When supplying powder from the powder container 62 to the distribution disk 20, the powder is dropped from the powder container 62 onto the distribution disk 20 while rotating the distribution disk 20 by the disk motor 32. As a result, an annular pile of powder is formed on the distribution disk 20. The annular powder formed on the distribution disk 20 is dropped one package at a time into the drop hopper 51 by the scraper 50.

The scraping unit 50 has a rotatable disk, and when the powder is supplied to the rotating distribution disk 20, the disk is separated from the distribution disk 20, and when the powder is distributed from the distribution disk 20, the disk is moved away from the distribution disk 20. It is configured to be able to come into contact with it. As the disk rotates, the powder rolled up on the distribution disk 20 can be dropped into the drop hopper 51 one package at a time. Such a scraping unit 50 is a well-known technique, and for example, the one described in Japanese Patent Application Laid-open No. 2019-202801 can be used.

As shown in FIGS. 2 and 3, the packaging device 70 is capable of diagonally conveying powdered medicines, that is, it is a horizontally conveying packaging device having a roll R around which a double-folded packaging paper 57 is wound. 70 is configured such that the bottom surface of the packaging device 70 is mounted obliquely to the packaging device. Then, the packaged paper 57 pulled out forward from the roll R located at the lower part of one of the distribution disks 20 is conveyed along the packaged paper conveyance path 71 diagonally downward at the front part, and is transferred to the lower part of the drop hopper 51. is inserted between the packaging papers 57, and the powder from the falling hopper 51 is accommodated between the packaging papers 57. The packaging paper 57 containing the powder medicine is further conveyed diagonally downward along the packaging paper transport path 71, and is heat-sealed one by one by a heat sealing section 72. Then, perforations are formed in the heat-sealed portion by the perforation forming section 73, and then the packaged powders are accumulated in the packaged powder accumulation section 75. Note that the packaged medicine containing the medicine may be wound up by a reel provided in the packaged powder medicine accumulation section 75, or it may be transported outside the machine and discharged.

Next, the powder medicine supply device 60 will be explained in detail using FIGS. 4 to 7.

FIG. 4 is a perspective view showing the powder supply device according to this embodiment, and FIG. 5 is a plan view thereof. FIG. 6 is a perspective view showing the vicinity of the driving-side rotating body and the passive-side rotating body of the powder supply device according to the present embodiment, and FIG. 7 is a perspective view showing a longitudinal section of the cover and powder storage container according to the present embodiment. It is a diagram.

As shown in FIGS. 4 and 5, the powder supply device 60 according to the present embodiment is equipped with a plurality of approximately cylindrical powder storage containers 62 that store powders in a detachable manner, and a container that can be transferred horizontally. A mounting section 61 is provided. The container mounting portion 61 according to this embodiment is formed into a substantially perfect circle, and 15 powder medicine storage containers 62 are attached along the outer peripheral edge of the container mounting portion 61 so as to be equally spaced apart in the circumferential direction. Therefore, the container mounting section 61 can transport the powder medicine storage container 62 so as to orbit in an annular orbit. The container mounting part 61 is suspended and supported so as to be able to rotate relative to a flat plate-shaped support member 41 fixed to the frame 40, and the support member 41 rotates a rotating shaft in the powder medicine storage container 62 to load the powder medicine. A supply motor 63 for supplying to the distribution disk 20 and a transfer motor 64 for rotationally driving the container mounting section 61 are provided.

In this embodiment, the following description will be made assuming that the supply motor 63 rotates counterclockwise and the transfer motor 64 rotates clockwise. Note that these motors may be rotated in opposite directions, or motors that can rotate in both directions may be used.

The container mounting section 61 is rotationally driven by the rotational drive of the transfer motor 64 being transmitted via the timing belt 66 . Specifically, a support shaft 42 connected to the support member 41 is provided with a bearing (not shown) around the support shaft 42, and the support shaft 42 is connected to the container mounting portion 61 in a relatively non-rotatable manner around this bearing. A pulley 67 is rotatably provided. A timing gear is formed on the outer periphery of the pulley 67, and by passing the timing belt 66 between the pulley 67 and the timing gear attached to the shaft of the transfer motor 64, rotational drive by the transfer motor 64 is controlled. This enables transmission to the container mounting section 61.

Therefore, as shown in FIG. 5, the clockwise rotation R1 of the transfer motor 64 causes the container mounting section 61 to rotate clockwise R2 in the same direction. Note that this configuration is not limited, and any mechanism that can rotate the container mounting section 61 may be used, such as attaching a motor to the support shaft 42 of the container mounting section 61.

As shown in FIG. 4, a powder discharge position P, which is a position for discharging powder, is set on the transfer trajectory formed by the container mounting section 61, and the container mounting section 61 is configured to transfer the powder storage container 62. Accordingly, the powder medicine storage containers 62 located at the powder discharge position P are sequentially switched. The powder discharge position P is set at a position where the medicine discharged from the powder medicine storage container 62 can be discharged to approximately the center in the radial direction of the annular groove formed in the distribution disk 20. To achieve this, for example, the central axis of the powder container 62 positioned at the powder discharge position P may be located at the radial center of the groove formed in the distribution disk 20.

A supply motor 63 is positioned above and near the powder discharge position P. The supply motor 63 is attached to the support member 41 so that the drive-side rotating body 106 provided at the tip of its rotating shaft faces downward, and when the powder container 62 is positioned at the powder discharge position P, It is close to the cover 65 located above the powder medicine container 62.

The covers 65 open and close the upper part of the powder medicine storage container 62, and are provided in the same number as the powder medicine storage containers 62 at the same pitch along the outer peripheral edge of the container mounting part 61. be transported. As shown in FIGS. 6 and 7, the cover 65 includes a box-shaped rotating body housing part 651 and a flat plate-shaped upper lid part 652 provided below the housing.

A pair of bearings 653 are formed in the upper lid part 652 and are fitted to a support shaft 611 provided on the outer periphery of the container mounting part 61 and extending in the left-right direction so as to be relatively rotatable. As a result, the cover 65 can be pivoted vertically by the support shaft 611, that is, by pivoting downward to a horizontal state, it can be brought to a closed state covering the upper part of the powder medicine container 62, and by pivoting upward to a closed state. They are each pivotably supported to be able to shift to an open state in which the state is released. By making the cover 65 openable and closable in this manner, the powder medicine container 62 can be left in an open state when it is removed, which will be described later, so that the removal work can be facilitated.

Inside the rotating body housing part 651, there is a transmission shaft 654 that can rotate together when connected to the rotating shaft 102 in the powder medicine storage container 62, and a passive rotating body 104 provided around the transmission shaft 654. It is provided. Therefore, when the powder medicine container 62 is positioned at the powder discharge position P, the passive rotating body 104 and the driving rotating body 106 of the supply motor 63 come close to each other via the rotating body housing part 651. .

In this embodiment, the passive rotating body 104 and the driving rotating body 106 form a magnetic non-contact power transmission mechanism formed of magnetic materials that magnetically interfere with each other. That is, in a state where the driving side rotating body 106 and the passive side rotating body 104 are close to each other, as shown in FIG. 5, when the driving side rotating body 106 rotates counterclockwise R3, the rotation R3 is caused by the magnetic force. As a result, the power is transmitted to the passive rotating body 104 in a non-contact manner, and the passive rotating body 104 rotates clockwise R4, which is the opposite direction to the driving rotating body 106.

In this way, when the rotational force is applied clockwise, the passive rotating body 104 rotates the rotating shaft 102 of the powder medicine container 62 via the transmission shaft 654, and the rotation of the rotating shaft 102 causes the powder medicine container 62 to rotate. can encourage the release of powder from the bottom of the A mechanism for discharging the powder from the powder container 62 by rotating the rotating shaft 102 will be described later.

By incorporating such a magnetic non-contact power transmission mechanism, a new mechanism for meshing the passive rotating body 104 and the driving rotating body 106 when the powder medicine container 62 is positioned at the powder discharge position P is created. Since it is not necessary to provide a powder, the mechanism can be simplified and the powder can be discharged in a short time after the powder medicine storage container 62 is moved to the powder discharge position P. Moreover, since deterioration such as wear of each rotating body due to contact can be avoided, cost reduction can be achieved.

Here, the passive side rotating body 104 and the driving side rotating body 106 are configured as a magnetic non-contact power transmission mechanism, but even if the power transmission mechanism is a contacting power transmission mechanism using rubber rollers or the like, the power transmission mechanism may be a power transmission mechanism based on a meshing structure of gears. Providing a new mechanism for that contact can also serve a similar purpose. In the case of a gear meshing structure, it is preferable from the viewpoint of maintainability that one gear is made of rubber and the other gear is made of metal, so that the rubber gear is managed as a consumable item.

Since the drive-side rotating body 106 is fixed near the powder discharge position P, when the powder medicine container 62 is switched and transferred by the container mounting section 61, the drive side rotating body 106 rotates every time the cover 65 and the powder medicine container 62 pass the powder discharge position P. , the passive rotating body 104 comes close to the driving rotating body 106. At this time, the magnetic force causes unnecessary rotation, that is, the powder medicine container 62 is transferred clockwise, and a counterclockwise rotational driving force is applied to the passive rotating body 104, causing the rotation shaft 102 to rotate, causing unwanted powder medicine to be delivered. may be released. In order to prevent this, in this embodiment, as shown in FIG. A one-way clutch type bearing 655 that can transmit data to the clutch 654 is interposed.

According to this bearing 655, the rotation of the passive rotating body 104 can be transmitted to the transmission shaft 654 to provide a rotational driving force for clockwise rotation. On the other hand, for counterclockwise rotation, the rotation of the passive rotating body 104 is not transmitted to the transmission shaft 654, and it is possible to avoid applying rotational driving force to the transmission shaft 654 due to idle rotation. Therefore, when the powder medicine storage containers 62 are transferred, the rotating shaft 102 of each storage container does not receive any rotational driving force, and it is possible to prevent the powder medicines from being discharged unnecessarily.

Next, the structure of the powder medicine container 62 will be explained using FIGS. 7 to 9.

FIG. 8 is a perspective view of the powder medicine storage container 62 according to this embodiment, and FIG. 9 is a schematic vertical cross-sectional view for explaining the internal configuration thereof. As shown in FIG. 8, the powder container 62 includes a cylindrical drug container main body 100 in which powders are stored, and a rotating shaft 102 rotatably provided within the drug container main body 100. The medicine container body 100 consists of an upper body 100a and a lower body 100b, and can be separated into the upper body 100a and the lower body 100b when cleaning the inside. Reference numeral 110 denotes a funnel member that is attached to the lower part of the medicine container main body 100 and collects the powder released from the medicine container main body 100 in the center below and supplies it downward.

As shown in FIGS. 7 and 9, a pair of upwardly protruding projections 103 (only one of which is shown in FIG. 7) is provided at the upper end of the rotating shaft 102 of the powder container 62. On the other hand, the lower part of the transmission shaft 654 included in the cover 65 protrudes below the upper lid part 652, and a pair of protrusions 656 protruding in the left-right direction so as to be able to engage with the pair of protrusions 103 is provided at the lower part. . These projections 103 and 656 come into contact with each other as the transmission shaft 654 rotates, resulting in a connected state, and the rotational drive of the transmission shaft 654 can be transmitted to the rotation shaft 102 to interlock with each other. Note that the reference numeral 105 shown in FIG. 7 is a lid member that covers the upper opening for supplying the powder into the drug container main body 100 of the powder container 62.

The mechanism for transmitting the rotation of the passive rotating body 104 to the rotating shaft 102 is not limited to this configuration, and for example, when the cover 65 is closed, an uneven portion formed on the transmitting shaft 654 and the rotating shaft 102 may be used. The transmission shaft 654 and the rotating shaft 102 may be integrated into one by attaching the cover 65 to the drug storage unit main body 100 instead of the container mounting part 61. Any configuration may be used as long as the rotation of the passive rotating body 104 can be transmitted to the rotating shaft 102.

As shown in FIG. 9, a plurality of first through holes H1 are concentrically formed in the lower part of the lower main body 100b, and below the first through holes H1 are fixed to the lower main body 100b and a plurality of second A bottom cover portion 114 is provided in which a through hole H2 is formed concentrically. A rotating body 116 is provided between the lower part of the lower main body 100b and the bottom cover part 114, and is connected to be rotatable integrally with the rotating shaft 102 and has a plurality of third through holes H3 concentrically formed therein. It is being The detailed structures of the lower main body 100b, the bottom cover 114, the rotating body 116, and the first to third through holes H1 to H3 will be described below with reference to FIGS. 10 and 11.

FIG. 10 is an exploded perspective view of the lower part of the powder medicine storage container according to the present embodiment, in which (a) shows the lower main body 100b, (b) shows the rotating body 116, and (c) shows the bottom lid part 114. shows. FIG. 11 is a diagram for explaining the relationship between the first through hole to the third through hole according to the present embodiment. For convenience of explanation, FIG. 11 shows a portion in which concentric through holes are developed and arranged in a straight line. As shown in FIG. 10, six first through holes H1-1 to H1-6 are formed concentrically at equal intervals on the bottom surface of the lower main body 100b, and six first through holes H1-6 are formed in the bottom cover part 114 at equal intervals. Second through holes H2-1 to H2-6 are formed concentrically at equal intervals. Thirteen third through holes H3-1 to H3-13 are formed concentrically at equal intervals in the rotating body 116.

Further, a center portion 116a of the rotating body 116 protrudes upward and extends into the lower body 100b through an opening 100c formed at the center of the lower body 100b. The lower part of the rotating shaft 102 provided inside the drug storage unit main body 100 is configured to fit into a fitting portion formed in the center portion 116a of the rotating body 116. As a result, the rotation of the supply motor 63 causes the rotating shaft 102 to rotate, and the rotating body 116 to rotate as well.

Here, the relationship between the first through holes H1-1 to H1-6, the second through holes H2-1 to H2-6, and the third through holes H3-1 to H3-13 will be explained. If the positions of the first through hole, the second through hole, and the third through hole overlap at the same time, the powder inside the medicine container main body 100 will fall all at once. In order to prevent this, the relationship between the first through hole, the second through hole, and the third through hole is as shown in FIG. 11.

(1) First, there are six first through holes H1-1 to H1-6 and second through holes H2-1 to H2-6, but the number is not limited to this. .

(2) Furthermore, the first through holes H1-1 to H1-6 and the second through holes H2-1 to H2-6 are formed at positions that do not coincide in the circumferential direction (positions where the holes do not overlap). ing. In the example of FIG. 11, the second through hole H2-1 exists between the first through holes H1-1 and H1-2.

(3) Furthermore, the width A in the rotational direction of the rotating body 116 of the third through hole H3-1 is the width A1 of the tip of the rotating body 116 in the rotational direction of the first through hole H1-1, and the width A of the second through hole H1-1. It is smaller than the distance B1 between the through hole H2-1 and the position b1 of the rear end of the rotating body 116 in the rotational direction.

(4) Similarly, the width A in the rotational direction of the rotating body 116 of the third through hole H3-2 is the same as the position a2 of the rear end in the rotational direction of the rotating body 116 of the first through hole H1-2. It is smaller than the distance B2 between the through hole H2-1 of No. 2 and the position b2 of the tip of the rotating body 116 in the rotational direction. The same relationship as (3) and (4) holds for other through holes.

Here, the distance B1 does not necessarily have to be equal to the distance B2, but it is more convenient for manufacturing if they are equal.

By setting the sizes and positions of the first through hole H1, the second through hole H2, and the third through hole H3 to the above relationship, the first through hole H1, the second through hole H2, and The third through holes H3 do not overlap at the same time.

Then, by rotating the rotating body 116 provided inside the medicine container main body 100 having the above-mentioned relationship, when the first through hole H1 and the third through hole H3 face each other, the medicine can be rotated. Powder inside the accommodating part main body 100 is accommodated in the third through hole H3 via the first through hole H1. Thereafter, as the rotating body 116 further rotates, when the third through hole H3 faces the second through hole H2, the powder stored in the third through hole H3 passes through the second through hole H2. and is emitted downward.

Note that if the number of third through holes H3 and the number of second through holes H2 are an integral multiple or a fraction of an integral number, the number of third through holes H3 and second through holes H2 may be multiple. They may face each other at the same time. With such a relationship, the amount of powder released will not always be equal.

(5) For this reason, the number of third through holes should not be equal to an integral multiple of the number of second through holes, nor be equal to an integral fraction of the number of second through holes. By this configuration, the amount of powder released can be made uniform.

By configuring the powder medicine storage container 62 as described above, the powder medicine inside can be discharged into the lower part in fixed amounts only by rotating the rotating shaft 102 in the container and rotating the rotating body 116. Furthermore, when the rotation of the rotating body 116 is stopped, the powder in the portion where the third through hole H3 and the second through hole H2 are opposed is only released downward, and from the other second through hole H2. No powder is released. Furthermore, since the first through hole H1 to the third through hole H3 do not all overlap, there is no need to separately provide an opening/closing body to prevent falling, so the configuration can be simplified.

In the present embodiment, the powder medicine storage container 62 has the above-described configuration and discharges the powder powder downward by the rotation of the rotating shaft 102. Any structure may be used as long as the powder in the powder medicine storage container 62 can be released downward by the rotation of the powder medicine storage container 62.

Next, attachment of the powder medicine container 62 to the container mounting portion 61 will be described using FIGS. 8, 12, and 13.

FIG. 12 is a perspective view showing a state before the powder medicine storage container 62 according to the present embodiment is attached to the container mounting section 61, and FIG. 13 is a perspective view showing a state after the powder medicine storage container 62 is attached to the container mounting section 61. It is a diagram. As shown in FIG. 8, a hook 100d is provided at the upper part of the outer peripheral wall of the upper main body 100a of the powder container 62, and a magnetic body 100e is provided below the hook 100d. On the other hand, as shown in FIG. 12, an insertion port 612 for the hook 100d is provided in the vicinity of the cover 65 on the outer peripheral edge of the container mounting portion 61, and a magnetic material 100e is provided below the insertion port 612. A magnetic body 613 that can be magnetically coupled with is provided. At both ends of the magnetic body 613 in the left-right direction, restraining plates 614 are provided, respectively, for restricting movement of the powder medicine container 62 in the left-right direction.

When attaching the powder medicine container 62 to the container mounting part 61, first open the cover 65 as shown in FIG. The magnetic body 100e is brought into contact with the magnetic body 613 of the container mounting portion 61 to be magnetically coupled. Thereby, as shown in FIG. 13, the powder medicine container 62 can be firmly attached to the container mounting section 61. Thereafter, by closing the cover 65, the transmission shaft 654 and the rotating shaft 102 can be linked to each other, as shown in FIGS. 7 and 9, and in this state, the powder container 62 can be opened. When the powder is transferred to the powder discharge position P, the powder can be discharged.

The control system of the powder medicine packaging device 1 will be explained in detail.

FIG. 14 is a block diagram showing a control system of the powder medicine packaging device 1 according to this embodiment. As shown in FIG. 14, the powder packaging device 1 according to the present embodiment includes a CPU (Central Processing Unit) 110a and a memory 110b including a RAM (Random Access Memory), a ROM (Read Only Member), etc. An overall control section 110 that performs main control of the powder medicine packaging device 1 is provided. The memory 110b stores container information 110c that includes information on the type of powder contained and current address of all the powder medicine storage containers 62 to be mounted, information on the address of the powder discharge position P, and the like. The overall control unit 110 is connected to the prescription system 200 of the pharmacy, and also controls the supply motor 63 and transfer motor 64 in the powder supply device 60, the weighing device 10, the disc motor 32, and the scraping unit 50 in the disc distribution unit. and the packaging device 70, respectively, so that their driving can be controlled.

Next, a series of operations from powder drug selection to powder drug packaging in the powder drug packaging device configured as described above will be described in detail with reference to FIG. 15.

FIG. 15 is a flowchart showing the operation of the powder medicine packaging device according to this embodiment. It is assumed that this flow is executed when the type information of the powder medicine to be prescribed and the weight information of the powder medicine for one prescription are input to the overall control unit 110 from the prescription system.

First, the overall control unit 110 acquires type information and weight information from the prescription system 200 (ST1), reads the container information 110c, and determines whether the type information and weight information satisfy predetermined conditions (ST2). The predetermined condition here is that the container information 110c includes the powder medicine storage container 62 (hereinafter referred to as the target container) that stores the powder medicine shown in the type information, and the target container has a weight distribution shown in the weight information. There is still some medicine left. If it is determined that the predetermined condition is satisfied (ST2, YES), the overall control unit 110 drives the transfer motor 64 to position the target container from the position indicated by the current address to the powder discharge position P (ST3). . At this time, if the target container 62 is already at the powder discharge position P, that is, if the current address is the address of the powder discharge position P, this step is omitted.

After the target container 62 is positioned at the powder discharge position P, the overall control unit 110 drives the disc motor 32 of the rotation drive unit 30 to rotate the distribution disc 20 (ST4), and supplies the powder to the distribution disc 20. The preparation is complete. Then, before the powder is supplied, the weight of the tare of the rotary drive unit 30 and the like is measured by the weighing device 10 (ST5). The weight of this tare bag may be subtracted from the weight measured after the powder is supplied to calculate the weight of the powder alone, or the weight of the powder only can be obtained using the value measured by the weight of the tare bag as a zero reference. You can. Further, the overall control unit 110 acquires the measurement results.

Thereafter, the overall control unit 110 drives the supply motor 63 of the powder supply device 60 (ST6) to drop the powder from the target container 62 into the distribution disk 20 little by little. While dropping the powder in this manner, the weight of the powder dropped onto the distribution disk 20 is measured by the weighing device 10 (ST7).

After that, while supplying the powder, it is determined whether the measured weight of the powder has reached the weight of one prescription amount (ST8), and the process continues until the weight of the supplied powder reaches the weight of one prescription amount. . When the measurement result reaches the weight of one prescription dose, the overall control unit 110 stops driving the supply motor 63 of the powder supply device 60 and also stops the disc motor 32 of the rotation drive unit 30 (ST9). When the powder for one prescription is supplied to the distribution disk 20, the overall control section 110 drives the scraping section 50 to move the disk so as to be in contact with the distribution disk 20, and then intermittently moves the disk and the distribution disk 20. As a result, the scraping unit 50 performs a scraping operation in which the powder medicine is dropped one package at a time into the drop hopper 51 (ST10). The powder medicines dropped into the drop hopper 51 are sealed one by one by the packaging device 70 and accumulated in the packaged medicine accumulation section 75.

On the other hand, in the process of ST2, if it is determined that the predetermined condition is not satisfied, that is, if it is determined that there is no target container 62 or that there is no powder remaining for one prescription amount shown in the weight information (S102, NO), The overall control unit 110 sends an error notification to the prescription system 200 (ST11), and this flow ends.

Here, the powder medicine packaging device 1 has the container information 110c and determines whether a predetermined condition is satisfied; however, the prescription system 200 has the container information 110c, and the powder medicine packaging device 1 has the container information 110c. Alternatively, the process may be performed starting from the process of ST3.

According to the present embodiment configured as described above, simply by transporting the plurality of powder medicine storage containers 62, it is possible to position them at the powder discharge position P and to discharge the powder medicines. Therefore, the selective transfer of the powder medicine container 62 and the discharge of the powder medicine can be completed with only two operations, and there is no need to perform operations such as taking out the powder medicine container 62. It is possible to shorten the time.

(Modification 1)
In addition, in this embodiment, although the powder medicine release position P was explained as one place, you may make it provide this in multiple places. FIG. 16 is a plan view showing a configuration in which two powder discharge positions are set on the distribution disk. For example, as shown in FIG. 16, the transfer trajectory T of the container mounting section 61 intersects the groove 20b formed in the distribution disk 20 for depositing powder at two points in a plan view. These two points are defined as first and second powder discharging positions P1 and P2, and by providing supply motors 63 in the vicinity of the first and second powder discharging positions P1 and P2, respectively, the first and second powder discharging can be performed. Powder can be discharged from the powder container 62 to the groove 20b at each of the positions P1 and P2.

As for the operation of this powder supply device, the operations ST6 to ST9 in the flow explained using FIG. 15 may be performed twice in succession. Specifically, after the processes of ST6 to ST9 are executed for the powder medicine container 62 located at the first powder medicine discharge position P1, and prior to the powder medicine scraping process of ST10, the powder medicine storage container 62 located at the second powder medicine discharge position P2 is processed. Processes ST6 to ST9 are executed for the powder medicine container 62. In addition, after the process of scraping out the powder in ST10, the process may be performed on the powder medicine storage container 62 located at the second powder discharge position P2. According to such a device, when it is desired to discharge powder medicine from two powder medicine storage containers 62, if there is only one powder medicine release position P, it is necessary to separately select and transfer the second powder medicine storage container 62. However, if the first and second powder discharge positions P1 and P2 are set, this transfer becomes unnecessary. Therefore, it is possible to shorten the working time until the powder is released into the distribution disk 20, and it is possible to further improve the efficiency of the work related to releasing the powder.

(Modification 2)
Furthermore, in this embodiment, a one-way clutch type bearing 655 is used as the one-way rotation mechanism to prevent unnecessary rotation of the rotating shaft 102 when the powder medicine container 62 is switched and transferred by the container mounting section 61. . However, a one-way rotation mechanism different from the one-way clutch type bearing 655 may be used to prevent unnecessary rotation of the rotating shaft 102 when switching and transferring the powder medicine container 62.

17 and 18 are diagrams for explaining different one-way rotation mechanisms, and show an enlarged perspective view of the vicinity of the lower part of the transmission shaft 654 of the cover 65 in the closed state. In this example, the transmission shaft 654 and the passive rotary body 104 are connected to be rotatable together and can be moved slightly upward, and a pair of protrusions 103 on the rotary shaft 102 are provided as shown in FIG. An inclined surface 103a is formed that ascends in a counterclockwise direction. According to such a configuration, even if a counterclockwise rotational driving force is applied to the passive rotary body 104 when the powder medicine container 62 is switched and transferred by the container mounting section 61, as shown in FIG. , each of the pair of protrusions 656 of the transmission shaft 654 slides up the inclined surface 103a of each of the pair of protrusions 103. This allows the transmission shaft 654 to rotate idly with respect to the rotating shaft 102, and it is possible to obtain the same effect as when a one-way clutch type bearing 655 is used.
