The first suction port forming piece 80a is a bottomed box-shaped part that is open at the top, and is laterally surrounded by an inner circumferential surface that continues in a substantially rectangular ring shape on the upper side of the bottom plate portion located on the lower end side. A hollow internal space 83 is formed.
The upper end surface of the first suction port forming piece 80a is an inclined surface that slopes downward toward the outside in the left-right direction. Therefore, the opening surface (suction opening) of the internal space 83 formed on the top surface is also a surface that slopes downward toward the outside in the left-right direction.

Among the inner wall surfaces of the internal space 83, brush engaging portions 84 that protrude inward are formed on respective surfaces that are spaced apart from each other in the left-right direction. A connecting hole 85 is formed in the upright wall portion located on the rear side of the internal space 83, passing through the upright wall portion in the thickness direction.
The brush engaging portion 84 is a raised portion having a substantially “concave” shape when viewed from the side, and a downwardly recessed fitting portion is formed in a part of the upper surface of the raised portion. Therefore, by fitting a portion of the lower end side of the brush body 81 into this fitting portion, it is possible to support the brush body 81.

When the extended route forming part 65 and the suction port forming part 66 are connected through the connecting hole 85 (see FIG. 4), the internal space of the extended route forming part 65 and the first suction port forming part of the suction port forming part 66 are connected. The inner spaces 83 of the piece 80a and the second suction port forming piece 80c communicate with each other.

The distal end hollow body 108 is a portion formed to protrude from the front surface of the external gear forming portion 107 toward the distal end side. The tip side hollow body 108 has a hollow body internal space 114 (see FIG. 8) formed therein, and communicates with the outside at the lower side (lower side during cleaning operation).

As shown in FIG. 7(b), the damming plate portion 109 has a wall shape that is formed to protrude further downward (outside) from the lower side of the tip nozzle portion 98 (lower side during cleaning operation). It is a part.
The damming plate part 109 includes a spatula-shaped part 109a formed of an elastic member such as rubber, and a splicing plate part 109b attached to the upper part (the proximal part in the protrusion direction) of the spatula-shaped part 109a. It has a structure. This spatula-shaped portion 109a has a smaller elastic modulus than the suction port forming plate portion 110.

As shown in FIG. 7B, the spatula-shaped portion 109a is divided into a distal side portion 115, a connecting portion 116, and a proximal side portion 117 in order from the distal end side of the distal nozzle portion 98.
The tip side portion 115 has a curved surface formed on its protruding end surface (lower end surface in FIG. 7(b)) so as to be convex toward the outside in the protruding direction (lower side in FIG. 7(b)). It is a part. The curvature of the curved surface is approximately the same as the curvature of the upper surface of the cross-sectional shape (cross-sectional shape cut along a plane perpendicular to the circumferential direction) of the powder injection groove 20a.
A recessed portion is formed on the lower end side of the connecting portion 116.

The splint part 109b has a protrusion length of the part located on the distal end side (right side in FIG. 7(b)) of the tip nozzle part 98, and the protrusion length of the part located on the proximal end side (left side in FIG. 7(b)). longer than length.
When the dam plate part 109 is viewed from the lower side (the lower side in the cleaning posture), as shown in FIG. 7(c), the spatula-shaped part 109a and the splint part 109b both have a curved and extending shape. It becomes.
That is, when the spatula-shaped portion 109a and the splicing plate portion 109b are viewed from above, both are curved so as to be convex toward the downstream side in the rotation direction of the distribution plate 20.

Specifically, the center portion of the spatula-shaped portion 109a and the splicing plate portion 109b in the direction of extension (longitudinal direction of the distal end hollow body 108) is larger in the rotational direction of the distribution plate 20 than both end portions in the same direction. It is curved so that it is located on the downstream side.
A part of the surface of the spatula-shaped portion 109a located on the downstream side in the rotational direction of the distribution plate 20 is in close contact with a surface of the splicing plate portion 109b located on the upstream side in the same direction.

As shown in FIG. 7(c), the suction port forming plate portion 110 has a distal end side portion 120 located on the distal end side (left side in FIG. 7(c)) of the distal nozzle portion 98, and a distal end side portion 120 located on the proximal end side of the distal nozzle portion 98. It is divided into a proximal side portion 121. This suction port forming plate part 110 is a part that is made of a material such as synthetic resin and is integrally molded with the tip-side hollow body 108. As shown in FIG. 7(b), it extends further downward (outward) on the lower side of the tip nozzle portion 98 (lower side during cleaning operation). Each part of the suction port forming plate part 110 has a shorter protruding length than each part of the dam plate part 109 adjacent in the rotational direction of the distribution plate 20.
Further, the lower end portion of the tip side portion 120 is closer to the dam plate portion 109 than the upper end portion.

The suction port forming plate part 110 and the dam plate part 109 are continuous with each other at their ends located on the distal end side of the distal nozzle part 98 (left side in FIG. 7(c)), and form an open end wall part 125. ing.
The portion on the proximal end side of the tip nozzle portion 98 (the right side in FIG. 7(c)) than the opening end wall portion 125 and between the dam plate portion 109 and the suction port forming plate portion 110 is operated for cleaning. It serves as a suction port portion 126 that sometimes functions as a suction port.

As shown in FIG. 8, the suction port 126 has a shape that has relatively wide intervals (widths) and relatively narrow intervals at each part in the longitudinal direction of the distal end hollow body 108.
In addition, the portion from the suction port portion 126 to the hollow body internal space 114 also has a portion with a relatively large cross-sectional area (cross-sectional area cut along a plane perpendicular to the longitudinal direction of the tip nozzle portion 98) and a portion with a relatively small cross-sectional area. It has a shape that has
That is, the shape of the portion extending from the suction port 126 to the hollow body internal space 114 differs depending on the longitudinal direction of the tip side hollow body 108 (the tip nozzle portion 98). On the other hand, in all parts, the upper part has a larger cross-sectional area than the lower part.

Inside the tip nozzle part 98, a series of spaces is formed from the suction port part 126 through the hollow body internal space 114, and spaces located inside the connecting cylinder part 105 and the proximal cylinder part 106, respectively. There is.
This series of spaces forms part of a series of spaces (upper suction path) that is connected to the internal space of the dish upper hose part 102 (see FIG. 6) and extends to the suction device (not shown).

As shown in FIG. 3, the scraping cleaning device 43 includes a disk insertion hole 130 (plate insertion hole) formed in the box of the tablet supply unit 11 and communicating between the inside and outside, and a cleaning mechanism located inside the box. It is composed of a main body 131.
The disk insertion hole 130 is a hole having an opening in a portion of the box of the tablet supply unit 11 spanning the front wall portion 11a and the bottom wall portion 11b.

Here, an inner partition wall 133 is formed on the back side of the opening of the disk insertion hole 130 formed in the front wall 11a. The inner partition wall 133 is continuous with the inner end in the left-right direction of the opening of the disk insertion hole 130 formed in the front wall 11a, and has a standing wall shape that extends outward in the left-right direction toward the back. It is a part.

The scraping plate 31 (see FIG. 13) of the scraping device 22 is inserted at a position on the back side of the opening formed in the front wall portion 11a of the disk insertion hole 130 and adjacent to the inner partition wall portion 133. This is a board storage area 134.
The cleaning mechanism main body 131 is located at the back side of the board storage area 134.

The cleaning mechanism body 131 includes a motor 137, a motor connection gear 138 integrally attached to the motor 137, and a rotating brush portion 139, as shown in FIG. 9(a). When the motor 137 serving as the drive source rotates, the motor connection gear 138 rotates, and the rotating brush portion 139 rotates accordingly.
The rotating brush section 139 includes a gear section 140 and a rotating brush main body 141 (rotating body), and the gear section 140 is in mesh with the motor connection gear 138.

The rotating brush main body 141 is a part formed by integrally attaching brush bristles (bristle bundles of brush bristles) to a part of the side surface of a substantially cylindrical main body part. The rotating brush main body 141 protrudes from one main surface of the gear portion 140 in a direction substantially perpendicular to the main surface and toward the outside.
The bristles attached to the rotating brush main body 141 are also made up of a plurality of elastic bristles densely packed together to form a bristle bundle (brush), and the plurality of bristle bundles are attached at different positions. The plurality of hair bundles form a scraping contact body that comes into contact with the scraping plate 31 during the cleaning operation. Furthermore, for convenience of drawing, each hair bundle is represented in a cylindrical shape.

As shown in FIG. 9(b), when the side surface of the rotating brush body 141 is unfolded, it is one continuous area (the area within the thick line in the figure), and its area is about 30% of the total area. Brush bristles (bristle bundles) are attached only within the area.
When the rotating brush main body 141 is unfolded from its side, it is divided into two regions, one region and another region, one of which is a region for attaching brush bristles, and the other is a region for attaching brush bristles. This area is where no brush bristles are attached.
Note that it is preferable that the area of the area to which the brush bristles are attached be larger than 0% and 50% or less based on the total area, from the viewpoint of preventing the brush bristles from scattering during operation.
As a modification, there is also a configuration in which the brush bristles are densely provided in some areas and very few brush bristles are provided in other areas.

The drug packaging device 1 of this embodiment operates each device (manual cleaning device 6, under-dish cleaning device 23, above-dish cleaning device 24, and scraping cleaning device 43) constituting the cleaning device group described above. Thus, the first to fourth cleaning operations can be performed.
Hereinafter, the first cleaning operation to the fourth cleaning operation will be explained in detail.

The first cleaning operation is a cleaning operation performed by operating the manual cleaning device 6.
In the first cleaning operation, the user operates the operation display section 3 and the like to perform the above-mentioned switching operation of the three-way valve, etc., as necessary. In the first cleaning operation, the user grasps the nozzle part 55 (see FIG. 1, etc.) of the manual cleaning device 6, and performs cleaning by bringing the suction port 55a close to or in contact with the part to be cleaned.

The second cleaning operation is a cleaning operation performed by operating the under-dish cleaning device 23, and the third cleaning operation is a cleaning operation performed by operating the above-dish cleaning device 24.
These cleaning operations can be automatically executed based on preset conditions. For example, among the packaging operations, it is possible to automatically perform the packaging operation before (or after) the packaging operation only when packaging a specific powder medicine. Further, regardless of the type of powder medicine, it is also possible to automatically perform the packaging operation before or after each packaging operation.
Furthermore, it is also possible to start cleaning on the condition that the operation display section 3 is operated by the user.

When the second cleaning operation is started, a suction path is formed between the suction device (not shown) and the under-dish cleaning device 23.
Then, an action is performed to rotate at least one of the plurality of (two) distribution dishes 20, and a suction operation is performed by the under-dish cleaning device 23.
Here, the brush bristles (bristle bundle) attached to the brush body 81 of the under-dish cleaning device 23 are attached so as to protrude upward from below, as shown in FIG.
For this reason, by disposing the suction port forming pieces (first suction port forming piece 80a, second suction port forming piece 80c) of the under-dish cleaning device 23 below the distribution plate 20, the brush can be brushed on the underside of the distribution plate 20. The contact is made with at least a portion of the hair being deformed.

The brush bristles come into contact with a position near the radially outer end of the lower surface of the distribution plate 20, and a portion thereof comes into contact with the distribution plate 20 from below. Specifically, it is a curved surface portion of the lower surface of the distribution plate 20 that is formed near the outer end in the radial direction, and is in contact with a curved surface portion that increases in height toward the outer side in the radial direction.
Further, the other part comes into contact with the radially outer edge portion from the side. In this state, while rotating the distribution plate 20, the under-dish cleaning device 23 performs a suction operation.

When the third cleaning operation is started, a suction path is formed between the suction device (not shown) and the dish cleaning device 24.
On the other hand, the dish cleaning device 24 changes from the standby position in which the opening of the suction port 126 faces upward (the position in which the suction port faces other than downward, see FIG. 6(a)) to the suction position facing downward. The position changes to the normal position (see FIG. 6(b)). That is, the tip nozzle portion 98 rotates, and the dam plate portion 109 rotates together with the suction port forming plate portion 110.

When changing the posture, the dam plate part 109 rotates together with the suction port forming plate part 110. The rotation of the tip nozzle section 98 uses the protruding direction of the tip nozzle section 98 as a rotation axis, and one direction around the rotation axis as a rotation direction. In this rotation direction, of the dam plate part 109 and the suction port forming plate part 110 which are arranged in parallel in the circumferential direction of the rotation shaft, the suction port forming plate part 110 side is the leading side, and the dam plate part 109 is the succeeding side. It is oriented towards the side.

When shifting to the cleaning position, as shown in FIG. 11, the lower end portion (projecting end portion) of the dam plate portion 109 comes into contact with the upper surface of the powder injection groove 20a.
Here, in this embodiment, as described above, by rotating the tip nozzle portion 98, the structure is made to shift to the suction posture. According to such a structure, there is an advantage that the powder is difficult to enter between the lower surface of the dam plate part 109 and the upper surface of the powder injection groove 20a.

Here, a case will be considered in which the damming plate part 109 is lowered vertically downward from above and brought into contact with the upper surface of the powder injection groove 20a. In this case, the lower surface of the dam plate part 109 descends from above the minute amount of powder, dust, etc. (hereinafter also simply referred to as dust) remaining on the upper surface of the powder drug input groove 20a, and as it continues, the upper surface of the powder drug input groove 20a come into contact with. As a result, dust and the like become trapped between the damming plate portion 109 and the upper surface of the powder injection groove 20a.
On the other hand, in the present embodiment, the dam plate part 109 rotates together with the tip nozzle part 98, so it moves from the downstream side in the rotational direction of the distribution plate 20 toward the position where it is in the cleaning posture. go. At this time, a part of the damming plate part 109 moves to a position where it is in the cleaning position while maintaining a state in which it is in contact with the upper surface of the powder injection groove 20a.
In this way, by moving the damming plate part 109 in a direction that includes not only the vertical component but also the circumferential direction component of the powder injection groove 20a, it is difficult for dust etc. to enter between the damming plate part 109 and the lower surface of the damming plate part 109. are doing.

In the suction position, the distal end side portion 115 of the dam plate portion 109 is fitted into the powder injection groove 20a. Therefore, the curved surface formed on the lower end side of the tip side portion 115 is in close contact with the powder injection groove 20a.
On the other hand, a part of the edge portion located on the radially inner side of the powder injection groove 20a and its vicinity enters into a recessed portion formed on the lower end side of the connecting portion 116.

In addition, the powder medicine input groove 20a is a recessed part that extends in an annular shape when viewed from above, and the cross-sectional shape taken by a cross section perpendicular to the circumferential direction is a recessed part that is rounded and convex downward. It is shaped like this. That is, the edge end portion located on the radially outer side and the edge end portion located on the radially inner side are arranged at a high position, and a depression is formed between them. The edge portions of the powder medicine input groove 20a located inside and outside in the radial direction are continuous in an annular shape when viewed from above.
Therefore, a portion that is located at a relatively high position on the inside of the powder injection groove 20a in the radial direction and that is continuous in an annular shape is inserted into the recessed portion formed on the lower end side of the connecting portion 116. It becomes a state.

After the plate cleaning device 24 shifts to the suction position, the distribution plate 20 is rotated. At this time, the rotation direction of the distribution plate 20 is such that the scraping device 22 is on the upstream side and the plate cleaning device 24 is on the downstream side (the direction shown by the arrow in FIG. 11(a)). Therefore, the damming plate part 109 in the cleaning position is located downstream of the suction port forming plate part 110 in the rotational direction of the distribution plate 20 (see FIG. 11(b)).

As shown in FIG. 12, in the cleaning posture, the lower end of the suction port forming plate part 110 is located at a higher position than the lower end of the dam plate part 109, and does not come into contact with the upper surface of the powder injection groove 20a. ing. Therefore, dust and the like accumulated on the upper surface of the powder injection groove 20a are collected on the upstream side of the dam plate portion 109 (upstream side in the rotational direction of the distribution plate 20) as the distribution plate 20 rotates. At the same time, the liquid is sucked into the tip-side hollow body 108 from the suction port 126.

In the third cleaning operation of the present embodiment, the tray cleaning device 24 is moved from the standby posture to the suction posture (first operation), and the suction operation is executed while rotating the distribution tray 20 one or more revolutions ( 2nd action). Subsequently, the plate cleaning device 24 is temporarily shifted to the standby position (third operation), and the distribution plate 20 is rotated by a predetermined angle (fourth operation). Furthermore, the dish cleaning device 24 is shifted to the suction posture again, and the distribution pan 20 is rotated at a predetermined angle to execute the suction operation (fifth operation), and then the dish cleaning device 24 is shifted to the standby posture. let In this way, the third cleaning operation is an operation in which a series of these operations is executed in sequence.

In the third cleaning operation of this embodiment, when rotating the distribution plate 20 in each of the series of operations, the distribution plate 20 is rotated in the same direction. That is, in a series of operations, the distribution plate 20 does not rotate in reverse. This configuration is preferable from the viewpoint of preventing collected dust and the like from being scattered as much as possible during cleaning.

The fourth cleaning operation is a cleaning operation performed using the scraping cleaning device 43 (see FIG. 3). The fourth cleaning operation can also be automatically executed based on set conditions. The fourth cleaning operation may be performed in parallel with other cleaning operations, or may be performed independently.

In this embodiment, the scraping device 22 assumes a standby posture in which the scraping plate 31 is positioned upward when the powder dispensing operation is not performed. By taking the standby position, a part of the scraping plate 31 is inserted into the disk insertion hole 130 on the side of the tablet supply unit 11 (see FIG. 13).
The fourth cleaning operation is an operation performed in this state, and is an operation in which both the scraping plate 31 and the rotating brush body 141 (see FIGS. 9 and 13) of the cleaning mechanism body 131 are rotated.

Specifically, during the cleaning operation, the rotating brush main body 141 is arranged such that its extending direction is the same as the thickness direction of the scraping plate 31. The rotating brush main body 141 is arranged at a position outwardly away from the side surface (the side surface continuous in the circumferential direction) located between the two main surfaces of the scraping plate 31.
Here, as described above, brush bristles (bristle bundles) are attached to a part of the side surface of the rotating brush main body 141 so as to protrude outward. Therefore, when the rotating brush body 141 is rotated, the brush bristles contact the scraping plate 31 when approaching the scraping plate 31, and contact the scraping plate 31 when moving away from the scraping plate 31. I will not do it. In other words, the brush bristles are brought into contact with the scraping plate 31 intermittently.

Here, the rotating directions of the scraping plate 31 and the cleaning mechanism main body 131 during cleaning may be the same direction or may be opposite directions. That is, both may rotate clockwise or both may rotate counterclockwise in a plan view (plan view with the line of sight direction as the extending direction of the rotating brush main body 141). Alternatively, one of the scraping plate 31 and the cleaning mechanism main body 131 may rotate clockwise, and the other may rotate counterclockwise.

Further, in this fourth cleaning operation, the cleaning operation may be performed in which the rotating brush main body 141 is rotated without rotating the scraping plate 31. In this case, the rotary brush body 141 is rotated and then stopped, the scraping plate 31 is rotated in the circumferential direction in this state, and the rotary brush body 141 is rotated again without rotating the scraping plate 31. May be implemented. That is, the cleaning operation may be performed while changing the cleaning target position of the scraping board 31.

In the embodiment described above, an example was shown in which the distribution plate 20 is rotated in the same direction in the second operation and the fourth operation, but the second operation and the fourth operation are not limited to such an operation. A mechanism for rotating the distribution plate 20 in the opposite direction may be provided, and in the fourth operation, the distribution plate 20 may be rotated in the opposite direction to the second operation.
To be more specific, when the second operation is performed, there is a possibility that fine powder remains in a linear manner between the dam plate part 109 and the distribution plate 20 along the radial direction of the distribution plate 20. Conceivable.
Therefore, after the third operation, a fourth operation may be performed in which the distribution plate 20 is rotated in the opposite direction to the second operation, and the distribution plate 20 may be shifted to the suction position again. Then, when shifting to the suction position again and bringing the dam plate 109 into contact with the upper surface of the distribution plate 20, the fifth operation is performed by bringing the dam plate 109 into contact at a different position than at the end of the second operation. It's okay.

In the above-described embodiment, an example has been described in which, when performing a cleaning operation with the dish top cleaning device 24, the posture is shifted from the standby posture to the suction posture and the suction operation is executed. However, the cleaning operation performed by the plate cleaning device 24 is not limited to this.
For example, the dish cleaning device 24 may perform a cleaning operation by performing a suction operation while in the standby position. Here, when the upper lid part 5 is in a closed state, a space surrounded by the upper lid part 5 and the powder medicine division area 10 is formed above the powder medicine division area 10 . Then, for some reason (as a result of some operation), there is a possibility that the powder to be supplied to the distribution tray 20 during the packaging operation will fly up into this space. That is, this cleaning operation is a cleaning operation that sucks the powder floating in the space above the powder divided area 10.

In addition, the third cleaning operation described above includes a first operation of shifting the dish top cleaning device 24 from the standby attitude to the suction attitude, and a second operation of executing the suction operation while rotating the distribution plate 20 one revolution or more. carried out. However, each operation executed in the first operation and the second operation, that is, the operation of shifting the dish top cleaning device 24 from the standby posture to the suction posture, the operation of rotating the distribution plate 20, and the suction operation are executed. The operations do not necessarily have to be performed in this order.
For example, the dish cleaning device 24 may perform a suction operation first, and then the dish cleaning device 24 may be moved to the suction position. At this time, the distribution plate 20 may be rotated before performing the suction operation, or may be rotated after the suction operation is performed and before the operation to shift to the suction position, or the distribution plate 20 may be rotated to the suction position. You can rotate it later. That is, the order in which these three operations are performed may be changed as appropriate, and any of the operations may be performed first, or any of the remaining two operations may be performed second.
Note that the rotation speed of the distribution plate 20 in the second operation may be changed as appropriate; for example, the distribution plate 20 may be rotated only one turn, rotated multiple times such as two or three turns, or rotated only half a turn. It may also be rotated by one-third of one revolution. That is, the rotation may be one revolution or less, and it is sufficient to rotate by a predetermined amount. Similarly, when making the amount of rotation larger than one rotation, for example, rotating one and a half rotations, or rotating two rotations and two-thirds of one rotation, when performing an operation of rotating n rotations, n is not limited to integers.

Further, the above-mentioned third cleaning operation (cleaning operation of the distribution tray 20 by the tray cleaning device 24) may also be an operation of performing the fourth operation and the fifth operation from the tray cleaning device 24 in the standby position. good. In other words, after performing an operation (fourth operation) of rotating the distribution plate 20 by a predetermined angle with the plate cleaning device 24 in the standby position, the plate cleaning device 24 is moved to the suction position, and the dispensing plate 20 is rotated by a predetermined angle (fourth operation). The suction operation may be performed while rotating the plate 20 at a predetermined angle.
Note that, at this time, the direction in which the distribution plate 20 is rotated is the same in each of the fourth operation and the fifth operation. That is, when the distribution plate 20 is rotated clockwise in plan view in the fourth operation, the distribution plate 20 is also rotated clockwise in plan view in the fifth operation. On the other hand, if the distribution plate 20 is rotated counterclockwise in plan view in the fourth operation, the distribution plate 20 is also rotated counterclockwise in plan view in the fifth operation.

Although the above-mentioned under-dish cleaning device 23 is disposed between the two distribution pans 20 and performs a suction operation during the cleaning operation (second cleaning operation), the under-dish cleaning device of the present invention is limited to this. It's not a thing. For example, an under-dish cleaning device 145 (lower side cleaning device) as shown in FIG. 14 may be used.
As shown in FIG. 14(a), the under-dish cleaning device 145 is a member formed by integrally fixing a scattering prevention plate 146 and a powder medicine tray member 147.

The anti-scattering plate 146 is a vertical plate-like member that extends in a curved manner. Specifically, when attached (FIG. 14(b)), the anti-scattering plate 146 is curved so as to be convex toward the outside in the radial direction of the distribution plate 20. It is extending. Note that at this time, it is preferable that the scattering prevention plate 146 be formed along the outer peripheral portion of the distribution plate 20. That is, it is preferable that the curvature of the curved portion and the curvature of the outer peripheral portion of the distribution plate 20 be approximately the same.
The powder medicine receiving tray member 147 has a bottom plate portion and a side wall portion, and forms a receiving space 148 that is a space surrounded by these portions. That is, the powder medicine receiving tray member 147 is a box-like member with a bottom, and the receiving space 148 is a space that is open at the top and depressed toward the bottom. The bottom plate portion of the powder medicine tray member 147 is curved so as to be convex downward, and its upper surface is concave.

This powder medicine tray member 147 is formed at a position adjacent to the lower end portion of the scattering prevention plate 146, and is arranged at a position adjacent to the distribution tray 20 side as shown in FIG. 14(b).
Further, a brush body 81 is attached to the receiving space 148, and the brush bristles (bristle bundle) are in a state of protruding upward. That is, the brush body 81 is attached above the bottom plate portion of the powder medicine tray member 147.

This under-dish cleaning device 145 is attached to a position close to the radially outer end of the distribution pan 20, as shown in FIG. 14(b).
At this time, most of the powder medicine receiving tray member 147 is located below the lower surface of the distribution tray 20. As a result, the brush bristles (bristle bundle) of the brush body 81 come into contact with the lower surface of the distribution plate 20 from below.
Further, the scattering prevention plate 146 extends along the circumferential direction of the distribution plate 20, and the inner surface of the scattering prevention plate 146 (the surface on the distribution plate 20 side) and the edge portion of the distribution plate 20 are slightly are placed close to each other with an interval between them.
Further, a part of the powder medicine tray member 147 is also located on the lower side of the space formed between the scattering prevention plate 146 and the edge portion of the distribution tray 20.

Further, it is preferable that the under-dish cleaning device 145 be installed at a position close to the supply port 282 (described in detail later) of the powder supply device 21. That is, it is preferable to install the supply port 282 so that it is located inside a portion of the scattering prevention plate 146.
Here, the under-dish cleaning device 145 includes a magnet member (not shown) formed of a permanent magnet, and can be attached to the mounting plate portion 10a (see FIG. 2) via this magnet member. . Therefore, the under-dish cleaning device 145 can be easily attached to and detached from the mounting plate portion 10a, and its attachment position can be easily adjusted.

The second cleaning operation by the under-dish cleaning device 145 is a cleaning operation performed by rotating the distribution plate 20 with the brush bristles in contact with the lower surface of the distribution plate 20.
Therefore, it is possible to carry out the cleaning operation in parallel with the various operations of rotating the distribution plate 20, that is, the operation of dividing the powder medicine into individual doses and the operation of supplying the powder medicine to the drug introduction port 25. There is. Further, this second cleaning operation can be performed in parallel with the cleaning operation (third cleaning operation) by the above-described dish cleaning device 24.

In the embodiment described above, an example was shown in which a plurality of bristle bundles (brush bristles) were employed as the contact body, but the present invention is not limited to this. For example, a foam such as a reinforced sponge may be used as the contact member. Also, felt, nonwoven fabric, etc. may be used.
However, from the viewpoints of durability during long-term use, cost, and efficient removal of powdered medicines, it is preferable to form the contact body with brush bristles.

The medicine package transport device 13 forms a transport path for transporting the medicine pack 14 (see FIG. 18, etc.) to the removal container 15, as shown in FIGS. 1 and 15. The medicine package transport device 13 is roughly divided into a primary transport section 160 located on the upstream side and a secondary transport section 161 located on the downstream side. Moreover, the take-out container 15 is provided so as to be rotatable in the front direction of the apparatus.

The primary conveyance section 160 is formed by arranging various members inside the outer shell member 160a. As shown in FIG. 16, the primary conveyance section 160 includes a first conveyor 165 (conveyor section), a second conveyor 166 (conveyor section), a press roller section 167, and a conveyance guide section 168 as main members. The structure is equipped with

The first conveyor 165 is a belt conveyor formed by winding a belt member (conveying surface forming member) around two conveyor rollers consisting of a first roller 165a and a second roller 165b, as shown in FIG. A conveyance path is formed diagonally downward.
That is, a transport path is formed from the portion of the medicine pack transport device 13 that serves as the introduction port for the medicine pack 14 (the right end side in FIGS. 15 and 16) toward the secondary transport section 161.

The second conveyor 166 is a belt conveyor located downstream of the first conveyor 165. This second conveyor 166 is a belt conveyor formed by winding a belt member (conveying surface forming member) around two conveyor rollers consisting of a first roller 166a and a second roller 166b, as shown in FIG. , forming a conveyance path that gently moves diagonally upward. The second conveyor 166 forms a conveyance path from the first conveyor 165 side to the secondary conveyance section 161. Reference number 169 is a tension roller.

As shown in FIG. 16, the presser roller section 167 has a structure including a mounting arm section 173, a power supply pulley 174, and a connecting roller section 175 formed by connecting a plurality of rollers. There is.

The mounting arm part 173 is a long plate-shaped member, and one end side in the extending direction is rotatably attached to the outer shell member 160a (see FIG. 15), and the other end side is attached to a part of the connecting roller part 175. It is installed against.
More specifically, one end side of the mounting arm portion 173 in the extending direction is rotated about an axis extending in the thickness direction of the mounting arm portion 173 as a rotation axis. It has a structure in which the end side can be moved in the vertical direction.
As a result, the connecting roller portion 175 connected to the other end in the extending direction of the mounting arm portion 173 can also rotate upward from the natural state (state where no external force is applied); It is possible to rotate downward from this position.

However, a rotation restriction portion 177 is formed on one end side of the attachment arm portion 173, and rotation of the attachment arm portion 173 beyond a certain level is restricted.
In other words, when the other end of the mounting arm 173 is rotated upward from the natural position, a part of the one end of the mounting arm 173 comes into contact with the rotation restricting part 177 and cannot be moved any further. rotation is prevented.

The connecting roller portion 175 is a portion formed by connecting a plurality of (three in this embodiment) rollers. The connected roller section 175 has a structure including a first press roller 180 (press roller), a second press roller 181 (press roller), and a third press roller 182 (press roller). It also includes a first connecting arm 185 and a second connecting arm 186 for connecting the plurality of rollers.

The first pressing roller 180 has two roller main bodies arranged in series, and one of the two roller main bodies has a larger diameter than the other.
The two roller main bodies belonging to the first pressing roller 180 are both members formed of an elastically deformable member such as foamed resin. The same applies to the roller main bodies belonging to the second press roller 181 and the third press roller 182 described below.
The first press roller 180 is integrally attached to the power supply pulley 174, and as the power supply pulley 174 rotates, the roller main body of the first press roller 180 rotates.

The second press roller 181 and the third press roller 182 also have two roller main bodies arranged in series. The diameters of the two roller bodies are the same.

Here, the first press roller 180 and the second press roller 181 are connected via a first connecting arm 185, and one of the first press roller 180 and the second press roller 181 is moved upwardly relative to the other. It is possible to move to. Therefore, the first press roller 180 and the second press roller 181 are in a state where they can freely rotate in the vertical direction with respect to each other while maintaining the state in which the roller main body portions thereof are rotated.
Similarly, the second press roller 181 and the third press roller 182 are connected via a second connecting arm 186, and each rotates in the vertical direction while maintaining the state in which the roller main body is rotated. It is in a state of freedom.

Further, each of the first press roller 180, the second press roller 181, and the third press roller 182 is provided with a belt winding section (detailed illustration is omitted) on which a belt member can be wound. One belt member is wound around each of the belt winding racks of the first pressing roller 180 and the second pressing roller 181, and another belt member is wound around each of the belt winding racks of the second pressing roller 181 and the third pressing roller 182. A belt member is wound around the belt.
That is, the first press roller 180 and the second press roller 181 are connected to each other so that power can be transmitted, and the second press roller 181 and the third press roller 182 are also connected to each other so that power can be transmitted. .
From this, when the roller main body belonging to the first press roller 180 rotates with the rotation of the power supply pulley 174, the roller main bodies belonging to the second press roller 181 and the third press roller 182 also rotate. It has a structure.

As shown in FIGS. 16 and 17, the conveyance guide section 168 is disposed near the downstream end of the second conveyor 166, and is a member having an inclined surface that increases in height toward the downstream side in the conveyance direction. It becomes. This inclined surface forms a part of the conveyance surface.
Further, a cutout 171 is formed in this inclined surface by cutting out a part near the upper end, and a part of the vertical conveyance belt member 218 (details will be described later) is placed in this cutout 171. It is in a state.

The secondary conveyance section 161 is a member that forms a conveyance path extending in the vertical direction, and as shown in FIG. It has a structure including a lid member 211 (lid portion).
In the secondary conveyance section 161, the lid member 211 is rotatably connected to the main body member 210 at one end in the width direction of the conveyance path, and the other end of the lid member 211 is moved toward and away from the main body member 210. It is possible to switch between the open state and the closed state.

The main body member 210 has a conveying surface forming part 162 arranged in a substantially vertical position and a main body side holding part 215 (holding part). The conveyance surface forming part 162 is a metal band, and serves to reduce friction with the medicine package 14.
The main body side clamping part 215 (clamping part) is located near the end of the conveying surface forming part 162 in the width direction.
The main body side holding part 215 has an upper pulley 216 and a lower pulley 217. The two pulleys 216 and 217 are both double pulleys, and are provided with two grooves for suspending the belt, and a vertical conveyance belt member 218 is suspended in each.
The vertical conveyance belt member 218 is a round belt with a circular cross-sectional shape. The shape of the vertical conveyance belt member 218 is arbitrary, and may be any one of a rectangular shape, a triangular shape, a V-belt, and the like. In any case, the vertical conveyance belt member 218 is a narrow belt.

A lid-side clamping part 220 (clamping part) is formed in the lid member 211 at a position near the end in the width direction of the conveyance path. This lid side clamping part 220 is a part that becomes a pair with the above-described main body side clamping part 215, and is a part that forms the clamping part together with the main body side clamping part 215.
This lid side clamping part 220 is a part formed by attaching a plurality of roller members 220a (gripping rollers) to a predetermined area extending in the vertical direction.
The plurality of roller members 220a are all idle rollers, and are arranged in parallel at intervals in the vertical direction. The extending direction of the shaft portion of the roller member 220a is the same as the extending direction in the width direction of the conveyance path. The roller body is made of a suitable elastic member such as rubber. That is, it is formed of a member that is elastically deformable but less deformable than each roller main body part belonging to the above-mentioned connecting roller part 175.

Then, by closing the lid member 211, each roller member 220a of the lid-side clamping portion 220 comes into contact with the vertical conveyance belt member 218.
Here, as shown in FIG. 16, the medicine package transport device 13 includes a motor 225 (power generating means) as a power source, and all driving parts are driven by one motor 225.
That is, the power supplied from the motor 225 causes each roller belonging to the first conveyor 165, second conveyor 166, and presser roller section 167 of the primary conveyance section 160 and the vertical conveyance belt member 218 of the secondary conveyance section 161 to move. It is rotationally driven.

Specifically, when the motor 225 rotates, the motor connection gear 228 rotates, and the interlocking gear 229 that meshes with the motor connection gear 228 rotates.
This interlocking gear 229 is integrally attached to the lower pulley 217 of the secondary conveyance section 161 and the second roller 166b of the second conveyor 166. Therefore, as the interlocking gear 229 rotates, the second roller 166b rotates, and the second conveyor 166 operates. Further, the lower pulley 217 rotates, and the vertical conveyance belt member 218 runs between the lower pulley 217 and the upper pulley 216 (see FIG. 17).

Then, when the second conveyor 166 operates, the first roller 166a of the second conveyor 166 rotates. Therefore, the first interlocking pulley 230 (FIG. 17), which is attached integrally with the first roller 166a and is rotatable about the same rotation axis, also rotates. Then, power is transmitted to the second interlocking pulley 231 connected to the first interlocking pulley 230 via the belt member, and the second interlocking pulley 231 rotates.
At this time, the second interlocking pulley 231 is integrally attached to the second roller 165b of the first conveyor 165 described above so as to be rotatable about the same rotation axis. From this, the second roller 165b rotates as the second interlocking pulley 231 rotates, and the first conveyor 165 operates.

A belt support pulley 232 is formed at a position separated from the second interlocking pulley 231 by a predetermined distance. The belt support pulley 232 is connected to the second interlocking pulley 231 via the belt member 163. Then, a part of the upper portion of the belt member running between the second interlocking pulley 231 and the belt support pulley 232 fits into a groove formed on the side surface of the power supply pulley 174. state, and is engaged with the power supply pulley 174.
The power supply pulley 174 is rotated by this belt member. As the power supply pulley 174 rotates, each roller main body part belonging to the connecting roller part 175 rotates.

The medicine package transport device 13 of this embodiment can make it difficult to damage the tablets inside when transporting the medicine package 14. Furthermore, it is possible to suppress the occurrence of wrinkles on the surface of the medicine package 14 and the occurrence of clogging of the medicine package 14 during transportation.
First, the medicine package 14, which is the object to be transported, will be explained.
In the drug packaging device 1 of this embodiment, drugs (tablets and/or powders) introduced into the drug inlet 25 (see FIG. 2) are packaged for each dose, and these are connected in a band shape into a drug package 14 (see FIG. 2). 18), and has a structure that can be supplied to the medicine package transport device 13.
As shown in FIG. 18, the formed medicine package 14 has a bag-like storage area 52 in which an internal space is formed to store each dose of medicine, and a non-bag-like storage area 52 where no medicine is stored. It is divided into a storage area 53.

The non-storage area 53 is a portion formed by sealing the periphery of the storage area 52 by means such as heat fusion, and includes a horizontal seal portion 53a extending in the lateral direction of the drug package 14 and a lateral seal portion 53a extending in the longitudinal direction of the medicine package 14. The structure has a vertical seal portion 53b extending vertically. Specifically, it has a structure including a row of vertical seal portions 53b and a plurality of horizontal seal portions 53a.
As shown in FIG. 18, the drug package 14 introduced into the drug package conveyor 13 is at least partially placed on the belt member (conveying surface) of the first conveyor 165, and continues as it is. It is transported downstream.
Then, the portions introduced into the medicine package transport device 13 in advance are sequentially moved onto the belt member (transport surface) of the second transport conveyor 166.

At this time, as shown in FIG. 19, in the downstream portion of the first transport conveyor 165, the lower portion of the first press roller 180 contacts the medicine package 14 from above. Furthermore, in the portion located on the downstream side of the second conveyor 166, the second press roller 181 and the third press roller 182 are in contact with the medicine package 14 from above at respective positions separated in the conveyance direction. It is in a state.

Here, as described above, the first press roller 180, the second press roller 181, and the third press roller 182 are the same (or substantially the same) as each conveyor (the first conveyor 165, the second conveyor 166). It has a structure that rotates at a speed of . That is, the pressing roller not only presses down the medicine package 14 but also applies a force to the medicine package 14 toward the downstream side in the transport direction.
For this reason, compared to a structure in which the presser rollers belonging to the connecting roller section 175 are idly rotated, the medicine package 14 being transported is less likely to wrinkle.

To be more specific, the drug packaging device 1 of this embodiment is capable of packaging not only powdered medicines but also tablets, as described above.
As described above, the medicine package 14 is divided into a storage area 52 in which medicine is stored and a non-storage area 53 in which medicine is not stored. When a plurality of tablets are stored in one storage area 52, a bulge may be formed in the storage area 52 depending on how they overlap (see FIG. 19(b)).

If the holding rollers are configured to idle, the rollers may not rotate normally due to getting caught in the bulging portion of the medicine package 14 or the like.
In this case, since the rollers act as resistance, the lower part of the medicine package 14 that comes into contact with the belt member of the second transport conveyor 166 precedes the upper part of the medicine package 14 that comes into contact with the roller. , wrinkles may occur on the surface of the medicine package 14.
In addition, if only the lower portion moves forward, the medicine package 14 may not be able to maintain its normal posture during normal transportation, and may become twisted. Such kinks may cause clogging during transportation.

In contrast, in the drug packaging device 1 of this embodiment, each roller belonging to the connecting roller section 175 is configured to rotate by the supplied power, and one side of the drug package 14 in the vertical direction is opposed to the other side. The structure makes it difficult to get ahead of the competition.
Furthermore, as described above, since each roller belonging to the connecting roller section 175 is attached to the other rollers so as to be able to rotate in the vertical direction, as shown in FIG. 19(b), the medicine packaging Each roller moves up and down depending on the bulge of the body 14.
That is, each roller moves upward (in a direction away from the upper surface of the medicine package 14) according to the size of the bulge when the bulge of the medicine package 14 passes under the roller. For this reason, each roller is less likely to cause resistance during conveyance, and wrinkles are less likely to occur in the medicine package 14.

In other words, this embodiment uses not only the conveyor consisting of the first conveyor 165 and the second conveyor 166, but also the conveyor and a plurality of rollers (the first press roller 180, the second press roller 181, and the third press roller 182). It has a structure in which the medicine package 14 is transported by.
According to such a structure, it is possible to efficiently apply a force toward the downstream side in the transport direction to the medicine package 14, and efficient transport is possible.

When a part of the medicine package 14 reaches the downstream end of the second transport conveyor 166, the reached part rides on the inclined surface (curved surface) of the transport guide section 168, as shown in FIG. state.
Then, at least the vertical seal portion 53b of the medicine package 14 rides on the conveyance guide portion 168, and the vertical seal portion 53b comes into contact with the vertical conveyance belt member 218 disposed in the missing portion 171.

Here, when the two vertical conveyance belt members 218 are running, a part of their lower ends and extending in the vertical direction is arranged in the missing part 171, and always moves from the lower side to the upper side. There is.
Therefore, the vertical seal portion 53b that has come into contact with a portion of the two vertical conveyance belt members 218 moves upward together with a portion of the two vertical conveyance belt members 218. Then, it enters between the roller member 220a and the two vertical conveyance belt members 218.

Here, as described above, when the lid side clamping part 220 (see FIG. 17) is in the closed state, the roller member 220a formed on the lid side clamping part 220 and the two vertical conveyance belt members 218 come into contact with each other. The state will be as follows.
At this time, since the two vertical conveyance belt members 218 (in this embodiment, the roller member 220a is also formed of an elastic member), the medicine package 14 is pushed between them. enters between these (see Figure 21).

That is, the vertical seal portion 53b moves upward until it reaches a position where the roller member 220a and the two vertical conveyance belt members 218 are in contact with each other. Then, the vertical seal portion 53b enters between the roller member 220a and the two vertical conveyance belt members 218 while maintaining the state in which it is in contact with the two vertical conveyance belt members 218. Thereafter, the medicine package 14 passes through these spaces and continues to move upward.
That is, the secondary conveyance section 161 is a device that conveys the medicine package 14 upward while holding the non-storage area 53 of the medicine package 14 using the roller member 220a and the two vertical conveyance belt members 218. More specifically, it is a device that conveys the product upward while holding a plurality of locations separated in the vertical direction in the non-storage area 53.

In this way, according to the structure in which the non-storage area 53 of the medicine package 14 is held and conveyed, the tablets packaged inside the medicine package 14 are sandwiched between the roller member 220a and the vertical conveyance belt member 218. It is preferable because it will not be damaged. Further, it is preferable that the bulge formed in the medicine package 14 is not pinched between the roller member 220a and the vertical conveyance belt member 218.
Then, the medicine package 14 that has been transported to the upper end side of the secondary transport section 161 is supplied from the secondary transport section 161 to the take-out container 15 (see FIG. 15, FIG. 21, etc.).

In addition, although the above-mentioned embodiment showed the example which adopted the belt conveyor as a conveyor part, this invention is not limited to this, For example, it is a roller conveyor formed by combining a drive roller and a driven roller. Good too. The conveyor section may be any conveyor that operates by the power supplied to the member forming the conveyance surface.

In this embodiment, the formed drug package is divided into a storage area for storing the supplied medicine and a non-storage area adjacent to the edge of the storage area, and at least a secondary conveyance section forming a part of the drug package, the secondary conveyance section having a clamping section that clamps the non-accommodating area of the medicine package, and holding the non-accommodating area with the clamping section; The medicine package is conveyed upward.

Furthermore, the secondary conveyance section includes a main body and a lid, a part of the clamping part is formed on one of the main body and the lid, and the other part of the clamping part is formed in the The holding portion is formed on the other of the main body portion and the lid portion, and a portion of the holding portion is one or more belt members, and the belt member is made of an elastic material and has a cross-sectional shape. The holding portion extends in a circular or cylindrical shape, and the other part of the holding portion is one or more holding rollers, which rotate around an axis extending in a direction intersecting the conveyance direction.

Furthermore, the power generation means also supplies power to each of the conveyor section and the clamping section.

As described above, the medicine packaging device 1 of this embodiment has a structure including the operation panel 7 (see FIG. 1). This operation panel 7 is a so-called touch panel, and is formed by combining a display device such as a liquid crystal panel and a position input device such as a touch pad.

As shown in FIG. 22, this operation panel 7 is divided into a plurality of areas, and these multiple areas include areas that function as various buttons when pressed with a finger or the like. ing. Specifically, a start button section 250, a stop button section 251, a set plate opening/closing button section 252, and a tablet supply start button section 253 are formed as areas having functions as operation buttons. Further, a remaining number display section 254 that displays the remaining number of sachets and two speed changing sections 255 are provided.

The start button section 250 is an area that is pressed to start the drug packaging operation. The stop button section 251 is an area that is pressed when it becomes necessary to stop the packaging operation in progress for some reason.
The set plate opening/closing button section 252 is an area that is pressed to open/close a predetermined portion of the tablet dispensing section 40 (see FIG. 1) of the tablet supply unit 11.
The tablet supply start button part 253 is a part that is pressed when starting a packaging operation for tablets.

The remaining number display section 254 displays the current number when packaging drugs one dose at a time in the ongoing packaging operation and finally forming the drug package 14 in which one or more doses of the drug are packaged. This is the part that displays the number of unpackaged medicines for one dose.

The two speed changing units 255 correspond to different powder supply devices 21 (see FIG. 2, which will be described in detail later). This speed change unit 255 serves as a part that indicates the current supply speed (amount of vibration) when supplying powder medicine from the powder supply device 21 to the distribution tray 20, and a part that performs an operation to change the supply speed. It is.

More specifically, the speed changing unit 255 is a part that displays the supply speed using a bar graph. In other words, a plurality of bar-shaped parts arranged in parallel at intervals are displayed, and as the feeding speed increases, the display color of each bar-shaped part changes from one end side to the other end side in the parallel direction. There is.
For example, when the powder medicine supply operation is not being performed, all the rod-shaped parts are displayed in a normal color (first color). Furthermore, when the feeding speed is set to the slowest, only one rod-shaped portion located at one end in the parallel direction is displayed in the changed color (second color), and the other rod-shaped portions are displayed in the normal color. be done. Then, when the supply speed is set to the highest speed, a display is performed in which all the bar-shaped portions are displayed in the changed color.

When changing the supply speed, the speed can be changed by touching the speed changing part 255 with a finger or the like and moving it in the parallel direction of the rod-shaped parts, as shown in FIG. 22(a).
In other words, by moving a finger, etc. from one end side to the other end side in the parallel direction of the rod-shaped parts, the supply speed increases as the finger, etc. moves, and by moving the finger, etc. in the opposite direction, the supply speed of the finger, etc. increases. As it moves, the supply speed decreases.

Further, as another speed changing operation, as shown in FIG. 22(b), the speed can be changed by performing a short touching operation with a finger or the like one or more times.
If the supply speed is neither the maximum nor the minimum, use the part that indicates the current speed as the reference position, and touch the position that is closer to one end of the rod-shaped parts in the parallel direction than the reference position to determine the specified speed from the current speed. The speed will be reduced by the value. On the other hand, if the other end is touched, the speed increases by a specified value from the current speed (FIG. 22(b) shows a speed increase operation).

In addition, when the supply speed is the minimum, the bar-shaped part (or its vicinity) located closest to one end in the parallel direction of the bar-shaped parts is used as the reference position, and the part that is on the other end side of the reference position is touched with a finger, etc. This increases the speed by the specified value from the current speed.
Note that when a finger or the like touches a position away from the reference position on the opposite side (a position further away from one end in the parallel direction of the rod-shaped parts), the speed does not change.

In addition, when the supply speed is the maximum, the bar-shaped part (or the vicinity thereof) located furthest to the other end in the parallel direction of the bar-shaped parts is set as the reference position, and the part that is closer to one end than the reference position is touched with a finger, etc. This causes the speed to decrease by the specified value from the current speed.
Similarly, when a finger or the like touches a position away from the reference position (a position further away from the other end in the parallel direction of the rod-shaped parts), the speed does not change.
As described above, the speed change unit 255 of this embodiment is capable of performing two speed change operations, and the user can select and execute an appropriate speed change operation.

The drug packaging device 1 of this embodiment has a structure in which small lid portions 5a, 5b, and 5c (see FIG. 1) formed on the upper lid portion 5 can be individually opened and closed.
Of these, the two small lid parts 5b and 5c are parts that are opened when supplying the powder medicine to be packaged to the medicine packaging device 1, and are respectively used for separate powder medicine supply devices 21 (see Fig. (see 2). When these are opened, the hopper arrangement area 260 located below can be exposed to the outside as shown in FIG. 1 (in FIG. 1, the small lid portion 5c is opened). )

The hopper arrangement area 260 is a space surrounded by a lower plate part 260a and a side wall part 260b that stands up near the edge of the lower plate part 260a. This hopper arrangement area 260 is an area for arranging an upper portion of a hopper 261 (described in detail later).

An information reading device 263 is attached to one of the side walls 260b.
This information reading device 263 is capable of reading information stored in an RFID tag (information storage means). That is, it is possible to read information stored in an RFID tag attached to a container for transporting powdered medicine (not shown, hereinafter simply referred to as a transport container) such as a weighing plate.

Here, information reading devices 263 are individually attached to the two hopper placement areas 260 (the hopper placement areas 260 located inside each of the small lid portions 5b and 5c).
Since the two hopper arrangement areas 260 each correspond to different powder supply devices 21, the powders put into the hopper 261 of one hopper arrangement region 260 are distributed from one powder supply device 21 to one of the powder supply devices 21. It is supplied to the dish 20 (details will be described later). Moreover, the powders put into the hopper 261 of the other hopper arrangement area 260 are supplied from the other powder supply device 21 to the other distribution tray 20 .

Therefore, when a predetermined powder stored in a transportation container is put into one of the hoppers 261, by bringing the transportation container close to the information reading device 263, the information stored in the RFID tag of the transportation container is read. Read operation is possible.
Through this information reading operation, it is possible to read information regarding the powder contained in the transportation container, and a determination operation is performed to determine whether or not the dispensing tray 20 that is about to supply a predetermined powder is correct. It is possible.

Although not particularly limited, if the dispensing tray 20 to which the powder medicine is to be supplied is incorrect after performing the above-described determination operation, a notification operation may be performed to notify that fact.
This notification operation may be an operation of displaying a message or an image on the operation display unit 3, or an operation of installing a speaker device or the like to play audio, or an operation that performs both of these operations. You can.

Furthermore, by storing information regarding the packaging operation using the contained powder in the RFID tag of the transportation container, it becomes possible to acquire information regarding the unperformed packaging operation through the information reading operation.
Therefore, after the information reading operation is performed, the dispensing tray 20 to which powder medicine is to be supplied and the equipment that operates when performing the dispensing operation with this dispensing tray 20 are moved to a standby state before performing the dispensing operation. may be implemented. For example, it is possible to display on the operation display section 3 prescription information for starting a dispensing operation and information indicating that an operation instruction for the dispensing tray 20 corresponding to the information reading device 263 has been acquired. When each device is in a standby state, if necessary, these devices may perform a preliminary operation before performing the packaging operation.
Furthermore, after performing the information reading operation, a cleaning operation (the above-mentioned cleaning operation) is performed that targets the dispensing tray 20 to which powder medicine is to be supplied and the scraping device 22 associated with this dispensing tray 20. You can.

In this embodiment, the information reading device 263 is provided on one of the side walls 260b adjacent to the hopper placement area 260, but the information reading device 263 may be installed at a position spanning a plurality of side walls 260b. good.
Further, although the information reading device 263 is provided on the side wall portion 260b and the RFID tag is provided on the transportation container, an RFID tag may be provided on the side wall portion 260b and an information reading device may be provided on the transportation container. That is, the information reading device 263 may be provided on either one of the portion adjacent to the hopper placement area 260 or the transportation container, and the RFID tag may be provided on the other.

Here, when the hoppers 261 are arranged in the respective hopper arrangement areas 260, the powder supply device 21 (see FIG. 2) is positioned below the hoppers 261. Then, as shown in FIG. 23, the hopper 261 into which the powder is introduced and the powder supply device 21 are placed adjacent to each other.
The powder supply device 21 has a structure including a supply trough 270 (trough member) disposed below the hopper 261 and a vibration device (vibration application device). The structure is such that the supply trough 270 vibrates when the vibration device operates. Note that it is preferable that the vibration device controls the number of vibrations according to the value of a hygrometer (not shown) provided in the device.
When the powder is loaded into the hopper 261, the powder falls onto the supply trough 270. Then, as the supply trough 270 vibrates, the powder moves over the supply trough 270 toward the supply port 282 (described in detail later), and from the supply port 282 to the powder injection groove of the distribution plate 20. Fall to 20a.

The supply trough 270 of this embodiment has a structure that can be attached to and detached from the main body of the powder supply device 21 (hereinafter also referred to as the supply device main body 21a).
Specifically, as shown in FIG. 24, the powder supply device 21 has a structure including a supply device main body portion 21a and a supply device lid portion 21b.
The supply device main body section 21a includes a saucer placement section 271 on which a supply trough 270 (see FIG. 23) is placed, and a locking mechanism section 272 (first main body side engaging section).
On the other hand, as shown in FIGS. 23 and 24, the supply device lid section 21b is rotatably attached to the supply device main body section 21a, and the end side located near the supply opening section 282 is attached to the supply device main body section 21a. By moving it upward, it becomes possible to shift from the closed state to the open state.
Then, as shown in FIG. 24, by opening the supply device lid section 21b, the locking mechanism section 272 is exposed to the outside.
In other words, by opening the supply device lid section 21b and unlocking the locking mechanism section 272, the supply trough 270 becomes removable from the saucer placement section 271.
This will be explained in more detail below.

As shown in FIG. 25, the supply trough 270 includes a saucer body 275 and a fixing member 276, which are integrally fixed.
The saucer main body portion 275 has a structure including a saucer bottom plate portion 280 having a substantially rectangular shape in plan view, and a saucer side wall portion 281 formed to protrude upward from the edge of the saucer bottom plate portion 280. ing. The distal end of the saucer main body 275 serves as a supply port 282 .
A plurality of raised parts 280a (three in this embodiment) are formed on the upper surface of the saucer bottom plate part 280 at a portion closer to the downstream end in the longitudinal direction of powder flow.
Further, a portion of the lower surface of the saucer bottom plate portion 280 that is closer to the upstream side in the flow direction of the powder is a portion for fixing the fixing member 276.
In addition, in the following description, the upstream side and the downstream side in the flow direction of powder medicine are also simply called an upstream side and a downstream side.

The fixing member 276 includes a fixing plate portion 276a having a substantially rectangular flat plate shape, and a hooking piece portion 276b (second trough side engagement (part, latching piece). Furthermore, the fixing plate part 276a has a structure including a lock piece forming part 276c formed by bending the other end side in the longitudinal direction of the fixing plate part 276a upward.
The fixed plate portion 276a is a plate-shaped portion extending in the longitudinal direction of the supply trough 270, and the length in the transverse direction is shorter at the downstream end side, which is one end side in the longitudinal direction.
The locking piece portion 276b has a shape in which a portion of the downstream end side of the fixing plate portion 276a is folded back toward the upstream side. That is, a portion that is continuous with the downstream end of the fixed plate portion 276a, a portion that extends toward the downstream while being curved to be rounded and convex, and a portion that extends from the downstream end of the fixed plate portion 276a to the upstream side. It has a part.

The lock piece forming portion 276c is formed by bending the upstream end side of the fixing plate portion 276a upward, and has a shape that projects upward at the upstream end side portion of the fixing plate portion 276a.
That is, the lock piece forming portion 276c is a plate-shaped portion that projects in an oblique direction toward the upper upstream side (the upper side and the outer side in the longitudinal direction of the fixed plate portion 276a).
The upper end portion of the lock piece forming portion 276c has a shorter length in the transverse direction (the width direction and the direction perpendicular to the protruding direction and the thickness direction) than the lower end portion.
A locking piece insertion hole 283 (first trough side engaging part) is formed in the upper end side of the locking piece forming part 276c. This locking piece insertion hole 283 is a through hole that penetrates the locking piece forming portion 276c in the thickness direction and has a rectangular opening shape.

This fixing member 276 is integrally fixed to the bottom of the saucer main body portion 275. A part of the upstream end side of the fixed plate part 276a projects further upstream than the part where the upstream end of the saucer bottom plate part 280 is located. The lock piece forming portion 276c continuous with the protruding end is located further upstream from the upstream wall-shaped portion (part of the tray side wall portion 281) of the tray main body portion 275.
As shown in FIG. 24, the saucer placement part 271 has a shape that includes a placement plate forming plate part 271a on which the supply trough 270 is placed, and a mechanism mounting plate part 271b on which the locking mechanism part 272 is attached. It becomes.

As shown in FIG. 24, the mounting table forming plate portion 271a is a plate-shaped portion extending along the longitudinal direction (flow direction of the powder) of the supply trough 270 at the time of attachment. The mounting table forming plate portion 271a has a hooking hole 284 (second main body side engaging portion, receiving portion).
The latching hole 284 is a hole that penetrates the mounting table forming plate portion 271a in the thickness direction, and has an opening having a substantially concave shape in plan view.
The mechanism attachment plate portion 271b is a flat plate-shaped portion that is continuous with the upstream end of the mounting table forming plate portion 271a, and is a portion that projects diagonally downward from this upstream end. The upper surface of the mechanism mounting plate section 271b is an inclined surface that is inclined with respect to the upper surface of the mounting table forming plate section 271a.

As shown in FIG. 26(b), the lock mechanism section 272 includes a mounting piece forming section 290 (second structure), an intermediate connecting section 291 (connecting body), and a hooking piece forming section 292 (first structure). It has a structure with a body). The locking mechanism part 272 is rotatably fixed between the attachment piece forming part 290 (second structure) and the intermediate connecting part 291 (connecting body), and between the intermediate connecting part 291 and the attaching piece forming part 290. It is also pivoted.
The locking mechanism section 272 is a toggle mechanism in which the above-described intermediate connecting section 291 and the hooking piece forming section 292 are used as links, and when the intermediate connecting section 291 is rotated as shown in FIG. Move with increased force.
In this embodiment, the intermediate connecting portion 291 has a structure including a sliding piece portion 301 and a spring member 302 (elastic member). The sliding piece 301 is attached so as to be movable in the front-rear direction, and when the sliding piece 301 moves forward, the sliding piece 301 is constantly urged backward by a spring member 302. It has a structure that allows

The hooking piece forming portion 292 is a box-shaped portion with open rear and lower sides, and a member storage space 313 (storage space) is formed inside thereof (lower side of the top surface).
The member storage space 313 is a space that can store substantially the entirety of the intermediate connecting portion 291 and the hooking piece forming portion 292, and is a space surrounded at both ends in the upper, front, and left and right directions.
Furthermore, a latching protrusion 315 is formed on the front side of the latching piece forming portion 292.
The latching protrusion 315 is a portion formed at the lower end of a vertical wall located in front of the latching piece forming portion 292, and is a protrusion that at least partially projects rearward.

The procedure for attaching the supply trough 270 to the saucer mounting section 271 will be described.
In this embodiment, an engagement structure section 278 is configured by the lock mechanism section 272 (first body side engagement section) and the latch piece insertion hole 283 (first trough side engagement section).
As shown in FIG. 26(a), the latching piece 276b is inserted into the latching hole 284 from above. Then, the supply trough 270 is moved to the rear side and the latch piece portion 276b is hooked to the edge portion of the latch hole 284.
In this state, as shown in FIG. 27(a), the latching piece forming part 292 is moved in the direction approaching the fixing member 276, and as shown in FIG. 27(b), the latching piece The forming portion 292 is brought close to the lock piece forming portion 276c from above, and the latching protrusion 315 is engaged with the lock piece forming portion 276c.
Then, as shown in FIG. 27(c), the locking piece forming portion 292 is pushed in to change the posture, and the locking mechanism portion 272 is shifted to the engaged posture (the state shown in FIG. 27(c)). .

The engaged posture is a state in which the locking piece forming portion 292 has moved slightly forward (upward in the direction of inclination of the mechanism mounting plate portion 271b) compared to the above-described standby posture (see FIG. 26(a), etc.). It becomes.
In this state, the hooking piece forming portion 292 is always urged toward the rear side. That is, the locking piece forming portion 292 is always urged downward and rearward in a state in which the locking protrusion 315 is inserted into the locking piece insertion hole 283. In this way, by shifting the locking mechanism portion 272 to the engaged position, the supply trough 270 is placed in a locked state.
As described above, in the powder supply device 21 of this embodiment, as shown in FIG. 28, one engaging part (first engaging part) is formed by the engaging projection 315 and the engaging piece insertion hole 283. ing. Furthermore, the locking piece portion 276b and the locking hole 284 form another engaging portion (second engaging portion). In this way, the supply trough 270 is engaged with the member on the supplying device main body 21a side at the rear side of the saucer main body 275 and the front side of the saucer main body 275.

Then, when the locking mechanism section 272 assumes the engaged position and the supply trough 270 enters the locked state, the latch protrusion 315 that becomes part of one engaging part and the latch that becomes part of the other engaging part Both of the stopper pieces 276b are constantly biased in a direction opposite to the direction in which they are moved when disengaging.
That is, since the latch piece forming part 292 is biased in a direction opposite to the direction in which it is moved when disengaging, the force applied from the latch piece forming part 292 causes the supply trough 270 to move. The entire structure is also on the upstream side (the left side in FIG. 27(c)) and is constantly pulled downward.
This makes it possible to firmly attach the supply trough 270 to the tray mounting portion 271. In other words, the structure is such that it does not come off unexpectedly even when subjected to vibrations, and can maintain its attached state. Note that by making the supply trough 270 and the saucer placement part 271 separate and removable, the supply trough 270 can be easily cleaned.

Note that, as shown in FIG. 28, the mounting table forming plate section 271a is fixed to the supplying device main body section 21a in an inclined posture so as to have a downward slope toward the downstream side (right side in FIG. 28). Therefore, when the supply trough 270 is attached to the saucer mounting section 271, it is fixed to the saucer mounting section 271 in an inclined posture.

Here, as shown in FIG. 25, the back surface of the fixing plate portion 276a, that is, the portion that becomes the lower surface when the saucer placement portion 271 is attached (see FIG. 26), has a surface that extends outward (downward when attached). A protrusion 286 is provided that protrudes.
Therefore, when the supply trough 270 is attached to the saucer mounting section 271, a gap is formed between the lower surface of the fixing plate section 276a and the upper surface of the mounting table forming plate section 271a at least around the protrusion 286. The Rukoto.
In this way, if the structure is such that the lower surface of the fixed plate part 276a and the upper surface of the mounting table forming plate part 271a are not brought into surface contact over the entire area, it is possible to suppress the generation of noise when the supply trough 270 is vibrated. Furthermore, even if a small foreign object gets between the fixing plate part 276a and the mounting table forming plate part 271a when the supply trough 270 is attached, the foreign object will be firmly sandwiched between them when the supply trough 270 vibrates. It can be a structure that is not maintained. In other words, it is possible to prevent a change in vibration caused by the foreign object being firmly sandwiched and vibrating (an adverse effect on vibrating with a specified vibration).

Moreover, in the powder supply device 21 of this embodiment, a vibration device is disposed inside the supply device lid portion 21b, and the vibration is transmitted from the supply device lid portion 21b to the hopper 261.
Here, as shown in FIG. 23, the supply device lid part 21b has a structure including a hopper movement restriction part 287 for preventing unintended movement of the hopper 261 during vibration.

Specifically, the hopper movement restriction section 287 is a portion consisting of a first movement restriction section 295 and a second movement restriction section 296 (cross direction restriction section).
The first movement regulating portion 295 is a raised portion that protrudes outward from the upper portion of the supply device lid portion 21b (the upper portion when the supply device lid portion 21b is closed) to the outside (also upwardly when the supply device lid portion 21b is closed). There is. Also, the top part is a curved surface.
The first movement restricting portion 295 is a portion that engages with a portion of the hopper 261 (in this embodiment, a missing portion formed in a protrusion projecting outward from the side surface of the hopper 261). That is, it is a part that restricts movement of the hopper 261 toward the supply port 282 (movement in a direction including the longitudinal component of the supply trough 270 at the time of attachment).

The second movement regulating portion 296 has a rod shape formed to protrude outward from the surface of the supply device lid portion 21b on the supply port portion 282 side when the supply trough 270 is attached and the supply device lid portion 21b is closed. It is a part. Specifically, it is a rod-shaped portion with a portion of the tip side bent downward.
More specifically, the two second movement restricting parts 296 are arranged in parallel so as to be separated from each other in a direction intersecting (orthogonal to) the flow direction of the powder medicine, and each extends toward the supply port part 282 side. There is. The hopper 261 is installed between the two second movement restriction parts 296, and when the hopper 261 is installed, each second movement restriction part 296 contacts a different side surface of the hopper 261. It has a structure.
That is, the second movement restricting portion 296 is a portion that restricts movement of the hopper 261 in a direction including the width direction component of the supply trough 270.

Here, in a state in which the supply trough 270 is attached and the supply device cover 21b is closed, the two second movement regulating parts 296 do not overlap with the supply trough 270 in plan view (the supply trough does not overlap in the vertical direction). 270).
For this reason, even if the powder that has fallen from above stays above the second movement restriction part 296, the structure is such that the powder on the second movement restriction part 296 will not fall into the supply trough 270. There is.

In the embodiment described above, the fixing member 276 is attached to the saucer main body 275, and the hooking piece insertion hole 283 is formed in a part of the fixing member 276 (locking piece forming part 276c), but the present invention is not limited to this.
For example, a structure may be adopted in which a portion of the saucer main body portion 275 (for example, a portion of the saucer side wall portion 281 located on the upstream side) is provided with a projection portion that projects upward, and a hooking piece insertion hole is provided.
Also, instead of the structure in which the hooking piece insertion hole 283 is directly formed in the fixing member 276, a connecting member (for example, a plate-shaped member) is fixed to the fixing member 276, and the hook is hung on the connecting member. A stopper insertion hole may be formed. That is, a structure may be adopted in which, when locked, force is applied from the latch protrusion 315 to the supply trough 270 via another member.

Further, in the above-described embodiment, an example was shown in which the supply trough 270 is provided with the hook portion 276b and is hooked into the hook hole 284 of the saucer placement portion 271 (see FIG. 28). It is not limited to this.
Instead of the hooking piece portion 276b, a plate-shaped portion projecting downward may be provided, and a through-hole serving as a receiving portion may be provided in this plate-shaped portion. In this case, a structure may be adopted in which a protruding portion is provided on the opening edge of the latching hole 284, and the protruding portion is inserted into and engaged with the through hole of the plate-shaped portion.
That is, a receiving portion may be provided on the supply trough 270 side, and a hooking piece may be provided on the saucer placement portion 271 side.
In the embodiment described above, the locking mechanism section 272 is provided in a part of the saucer mounting section 271, but the present invention is not limited to this. The locking mechanism section 272 may not be attached to the saucer mounting section 271, but may be attached directly to another part of the supply device main body section 21a.

In this embodiment, the supply device main body and the trough member each have a second main body side engaging part and a second trough side engaging part, which form a pair, and the second main body side engaging part and the second main body side engaging part form a pair. One side of the trough-side engaging portion is a locking piece, and the other side is a receiving portion capable of locking the locking piece, and when the trough member is attached to the main body of the supply device, the trough side engaging portion is A member is placed on a part of the main body of the supply device, the hooking piece is hooked to the receiving portion, and the first body-side engaging portion and the first trough-side engaging portion are connected to each other. The latching piece and the receiving part are in a latched state, and by moving one of the latching piece and the receiving part in a predetermined disengagement direction relative to the other, The latching is released, and when the first body-side engaging portion and the first trough-side engaging portion are engaged, a downward direction component and a direction component toward the trough member are generated. A force is applied in a direction including a directional component opposite to the release direction.
The connecting body includes an elastic member, and the elastic restoring force of the elastic member acts on the first structure in a predetermined direction, and the force is applied to the trough member via the first structure. join.
Furthermore, a hopper member is disposed above the trough member, and the powder supply device includes a hopper movement restriction section that restricts movement of the hopper member, and the hopper movement restriction section is arranged above the trough member. The device includes a cross-direction restricting portion that restricts movement of the powder medicine in a direction intersecting the flow direction of the member, and the cross-direction restricting portion is located at a position that does not overlap with the trough member in plan view.

As shown in FIG. 29, the drug packaging device 1 of this embodiment can be used with a tablet cassette shelf 350 (medicine shelf device) attached. That is, it also forms a part of a packaging device 351 with medicine shelf (medicine packaging unit) that includes the medicine packaging device 1 and the tablet cassette shelf 350.
The tablet cassette shelf 350 has a structure including a container mounting section 361 that holds a plurality of tablet containers 360, and a tablet feeding device 362 (tablet conveying device) located below the container mounting section 361.
The tablet cassette shelf 350 of this embodiment holds different types (two types) of tablet containers 360.
In the packaging device with medicine shelf 351, a part of the front side of the tablet feeding device 362 is inserted into a connecting opening (not shown) formed on the back side of the medicine packaging device 1. Furthermore, the front end side of the tablet extrusion path 484 (described in detail later) of the tablet feeding device 362 is connected to the rear end side of the tablet conveying path 41 (see FIG. 3), which is a part of the tablet feeding unit 11, so that a series of flow form a road.

When the tablets are supplied from the tablet cassette shelf 350 to the drug packaging device 1, the tablets that have fallen from the tablet container 360 are introduced into the tablet supply device 362 located on the lower side. Then, after being transported to the tablet extrusion path 484 inside the tablet feeding device 362, the tablet is pushed out from the tablet extrusion path 484 to the tablet conveyance path 41 (see FIG. 3).
The tablet feeding device 362 will be described in detail below.

As shown in FIG. 30, the tablet feeding device 362 can be roughly divided into a tablet receiving section 365 (introducing section) located on the upper side, and two horizontal transport sections 366 (primary transport section) on the left and right located below the tablet receiving section 365 (introducing section). and a falling route forming section 367 (route forming section). A tablet extrusion section 368 (secondary conveyance section) is formed below the falling path forming section 367.
Therefore, the tablet feeding device 362 includes a tablet receiving section 365 (introducing section) that extends horizontally, a horizontal conveying section 366 (primary conveying section) that also extends horizontally, and a tablet extrusion section 366 (primary conveying section) that extends vertically. The section 368 (secondary conveyance section) has a three-tier stacked structure vertically stacked.
The uppermost tablet receiving section 365 is a section for receiving tablets that have fallen from above, and is a section that functions as a tablet introducing section in the entire tablet feeding device 362.
This tablet receiving part 365 has a structure including a one-sided tablet receiving part 365a located at one end in the left-right direction (width direction of the tablet cassette shelf 350) and a second-side tablet receiving part 365b located at the other end. It becomes.

As shown in FIG. 30, the one-side tablet receiving portion 365a is a substantially rectangular parallelepiped-shaped portion extending in the left-right direction, and has three tablet introduction spaces 370 (storage spaces) formed therein.
Specifically, three tablet introduction spaces 370a, 370b, and 370c are provided in parallel at intervals, and a connecting member arrangement portion 371 and a partition member 372 are located between these spaces. In other words, the three tablet introduction spaces 370 are formed by dividing a space extending in the left-right direction by the connecting member arrangement portion 371 and the partition member 372 to form a plurality of spaces.
The connecting member arrangement section 371 is a space in which various members are arranged. The partition member 372 is a member that is integrally formed with a flat top plate portion located on the upper side and two upright plate portions located at both ends in the left and right direction.
Each of the three tablet introduction spaces 370 is a space that communicates with the outside at each of the upper and lower sides, and has an opening surface that serves as a tablet introduction port on the upper side. By rotating the rotating plate portion 384 (movable receiving member) shown in FIG. 31, it is possible to switch between a state where the lower side is closed and a state where the lower side is open to the outside.

The one-sided tablet receiving part 365a (see FIG. 30) has a structure that includes a motor 378, a power transmission part 379, and a rotational swing converting part 380, as shown in FIG. 31, as members disposed therein. It becomes. Furthermore, as shown in FIG. 31, the structure includes a first shaft 381, a shaft coupling member 382, a second shaft 383, two rotating plate parts 384, and a rotation regulating mechanism 385.
In the one-sided tablet receiving part 365a, the motor 378 is operated, and when the shaft of the motor 378 continues to rotate to one side around the axis (circumferential direction), the rotating plate part 384 swings. In other words, the structure is such that the rotating plate portion 384 can be swung without rotating the motor 378 in the reverse direction.
Therefore, as shown in FIG. 32, the one-sided tablet receiving portion 365a has a tablet receiving posture in which the lower side of the tablet introducing space 370 is closed by the rotating plate portion 384 (see FIG. 32(a)). It is possible to switch between the tablet ejecting posture (see FIG. 32(b)). In addition, in the tablet ejection position, the lower side of the tablet introduction space 370 is in a state of communicating with the space further below.
In other words, the portion located below the tablet introduction space 370 and connected to the outside serves as a discharge port for discharging the tablet to the outside.

The one-sided tablet receiving portion 365a waits in a tablet receiving posture and receives a tablet falling from the tablet container 360 (see FIG. 29, etc.). Then, by shifting to the tablet discharging position with the tablet disposed inside the tablet introducing space 370, the tablet is further supplied to the lower side (the horizontal conveying section 366 and the falling path forming section 367, see FIG. 30). In other words, after the tablets are temporarily stored inside the tablet introduction space 370, they are supplied to the lower side.
Here, as shown in FIG. 32(a), the rotating plate portion 384 has a portion that becomes an inclined surface that is inclined with respect to the horizontal plane and slopes downward toward the front side when in the tablet receiving posture. have. This portion is located above the portion that serves as a tablet discharge port, and serves as a portion that receives the tablets supplied to the one-sided tablet receiving portion 365a. That is, the tablets that have fallen onto the rotating plate portion 384 continue to slide down on the inclined surface and are collected on the lower side.
Of the three tablet introduction spaces 370, the tablets introduced into two predetermined tablet introduction spaces 370a and 370b are supplied to one side of the lateral conveyance section 366 in the intermediate stage, and are pushed laterally to form a falling path. The tablets are supplied to the tablet extrusion section 367 and introduced into the lowermost tablet extrusion section 368 (secondary conveyance section).
The tablets introduced into the other tablet introducing space 370c fall directly into the fall path forming section 367 without passing through the intermediate horizontal conveyance section 366, and then go to the lowest tablet extrusion section 368 (secondary conveyance section). be introduced.
The other side tablet receiving part 365b has the same basic structure as the one side tablet receiving part 365a, so detailed description thereof will be omitted. Note that the tablets introduced into the other side tablet receiving section 365b are supplied to the other lateral conveyance section 366.

Next, the intermediate stage lateral conveyance section 366 will be explained. Two horizontal conveyance units 366 are arranged in a straight line in the intermediate stage.
Since the two lateral conveyance sections 366 have the same structure, only one will be explained. As shown in FIG. 33, the horizontal conveyance section 366 has a structure including a drug receiving groove section 410 (receiving section), a wheel running section 411, a guide arrangement section 412, and a lower box section 413. ing.
More specifically, a wheel running section 411, a drug receiving groove section 410, and a guide arrangement section 412 are arranged in order from the front in the drawing, and are integrally formed. A lower box portion 413 is disposed below these.

The medicine receiving groove 410 is a part into which a tablet that has fallen from the tablet receiving part 365 described above is introduced, and is a groove-shaped part concave on the downward side, and has a substantially rectangular cross-sectional shape and extends in the left-right direction. It forms a space.
A tablet ejection port 418, which is an opening that communicates the inside and outside, is formed at one end of the drug receiving groove 410 in the longitudinal direction (the end on the near side in FIG. 33). The end where the tablet ejection port 418 is formed is the end located on the center side in the left-right direction of the tablet feeding device 362 (see FIG. 30, etc.). Two lateral conveyance sections 366 are arranged in a straight line in the middle stage, and the tablet ejection port 418 is located at a portion facing the two lateral conveyance sections 366 .

As shown in FIG. 33, a tablet extrusion piece 438 is disposed within the drug receiving groove 410. The tablet pushing piece 438 is disposed inside the drug receiving groove 410 and moves along the longitudinal direction of the drug receiving groove 410.
The mechanism for moving the tablet extrusion piece 438 is as shown in FIG. 34, and includes a linear guide member 452 constituted by a rail member 453 and a slider 454, a belt mechanism 446 driven by a motor 445, and a wheel portion 451. ing.
The tablet extrusion piece 438 is connected to the slider 454 of the linear guide member 452 and has a degree of freedom only in the linear direction. Further, the tablet pushing piece portion 438 is indirectly connected to the belt of the belt mechanism 446 via another member, and moves linearly within the medicine receiving groove portion 410 in accordance with the running of the belt. The wheel portion 451 supports the load of the tablet extrusion piece portion 438.

Therefore, by moving the tablet extrusion piece 438 inside the drug receiving groove 410, the tablet can be extruded.
That is, the tablet ejecting piece portion 438 is made to stand by at one end in the longitudinal direction of the drug receiving groove portion 410 and away from the tablet ejection port portion 418, and the drug is received from the tablet receiving portion 365 described above. The tablet is supplied (dropped) into the inner space of the groove 410.
Thereafter, the tablet extrusion piece 438 is moved along the longitudinal direction of the drug receiving groove 410 to the vicinity of the tablet ejection port 418, and the tablet is pushed out from the tablet ejection port 418.

As shown in FIGS. 30 and 35, the falling path forming portion 367 is a portion located below one tablet introduction space 370c. The fall path forming portion 367 has a vertical hole shape, and a first fall regulating plate 460 (regulating member) and a second falling regulating plate 461 (regulating member, see FIG. 35) are arranged inside.

As shown in FIG. 35, the first fall regulating plate 460 is formed by a pair of two regulating plate pieces 460a and 460b.
The upper surfaces of the two regulating plate pieces 460a and 460b are sloped surfaces that slope downward toward the center in the left-right direction. The tablet introduction port 480a of the tablet extrusion section 368 is located on the lower side between the lower end portions of the inclined surface. In other words, at the part where the two regulating plate pieces 460a, 460b are closest to each other, a gap is formed between the two regulating plate pieces 460a, 460b that communicates the upper side and the lower side, and the lower side of this gap A tablet inlet 480a is located at.
The shape of the second fall regulating plate 461 is also substantially the same as that of the first falling regulating plate 460.

The space adjacent to the upper side of the tablet introduction port 480a is surrounded by the two upright plate-like portions of the falling path forming portion 367, and the two regulating plate pieces 461a and 461b.
The lowermost tablet extrusion section 368 includes an inlet forming section 470 and an extrusion path forming section 473, as shown in FIG. As shown in FIG. 36, a tablet conveying device 474 for conveying the tablets supplied into the extrusion path forming section 473 is provided.

As shown in FIG. 36, the inlet forming part 470 is a member attached to the upper side of the extrusion path forming part 473, and has a first tablet supply hole 480 penetrating the inside thereof in the vertical direction. The opening located above the first tablet supply hole 480 serves as an introduction port (tablet introduction port 480a) when tablets are supplied to the tablet extrusion section 368.
The extrusion path forming section 473 has a tablet extrusion path 484, which is a space extending in the front-rear direction, formed therein.
This tablet extrusion path 484 has a tablet outlet portion 484a on the front end side, which is an opening portion that communicates inside and outside.
A tablet conveying device 474 is built into the extrusion path forming section 473.
As shown in FIG. 36, the tablet conveyance device 474 has a structure including an upper pedestal part 490 and a conveyor part 491 located below the upper pedestal part 490. The carrier section 491 is linearly moved within the tablet extrusion path 484 by a drive device (not shown).
The upper pedestal part 490 engages with the carrier part 491 by an engaging part (not shown), and moves linearly following the carrier part 491 up to a certain position, but after the certain position, the engagement between the two is delayed. The upper pedestal part 490 remains at that position, and only the carrier part 491 moves.
The upper pedestal section 490 is always pressed forward by a power source (not shown), and the carrier section 491 is connected to a drive device (transporter power section) not shown. There is.

The upper pedestal part 490 is formed with a tablet drop hole 510 which is a through hole penetrating in the vertical direction on the front side.
The carrier part 491 is a part for transporting tablets, and as shown in FIG. 36, a storage hole 520 is formed in a part thereof, passing from the top surface to the bottom surface.

Next, the tablet conveyance operation by the tablet extrusion section 368 of this embodiment will be explained.
The tablet extrusion unit 368 is capable of performing a first conveyance operation for conveying tablets for one dose, and a second conveyance operation for conveying tablets for multiple packages supplied one dose at a time. .
In the first transport operation, the tablet transport device 474 stands by in a first standby posture in which the upper pedestal part 490 and the transport body part 491 are both located on the rear side, as shown in FIG. 37(a). In addition, in this first standby posture, the first tablet supply hole 480, the tablet drop hole 510, and the storage hole 520 form a series of communication holes.

When a tablet is introduced into the tablet introduction port 480a with the tablet conveyance device 474 in the first standby position, the tablet falls inside the communication hole and reaches the inside of the storage hole 520 on the tablet extrusion path. A tablet is arranged at a position above the bottom plate portion of 484.
Then, in the first standby position, from the state where the tablets are stored in the storage position, the carrier section 491 is moved forward by operating a motor (not shown). At this time, the upper pedestal part 490 also moves forward as the carrier part 491 moves.

When the upper pedestal part 490 and the carrier part 491 move forward while maintaining the contact state, the upper pedestal part 490 becomes the state located furthest to the front within the movable range (Fig. 37 ( b) etc.). Then, after this, only the carrier section 491 moves further forward, and the carrier section 491 becomes separated from the upper pedestal section 490 toward the front side.
Then, as the carrier section 491 moves forward, the front portion of the carrier section 491 is positioned further forward than the tablet outlet section 484a (see FIG. 37(c)). At this time, the entire area of the lower opening of the storage hole 520 is positioned forward of the bottom plate portion of the extrusion path forming section 473. As a result, the tablet located inside the storage hole 520 falls downward, and the tablet is supplied from the tablet extrusion section 368 to the tablet conveyance path 41 (see FIG. 3).

Next, the second transport operation will be described, but redundant detailed explanation will be omitted for the same parts as the above-described first transport operation.
In the second conveyance operation as well, the tablet conveyance device 474 waits in the first standby position, and after the first package of tablets supplied first is stored inside the storage hole 520, conveyance is started. Then, it is transported in the same procedure as above, and as shown in FIG. 37(b), the upper pedestal part 490 is moved to the frontmost position.

Then, in the same manner as described above, the forward movement of the upper pedestal part 490 is stopped, and only the transport body part 491 moves forward, but at this time, in the second transport operation, the two packages to be subsequently transported are A second tablet (not shown) is supplied to the tablet introduction port 480a.
Specifically, the conveyor section 491 moves forward in the same manner as described above, and conveys the first package of tablets supplied in advance to the front side. That is, the front portion of the carrier section 491 moves to a state where it is located further forward than the tablet outlet section 484a (see FIG. 37(c)), and the first package is placed in the tablet transport path 41 (see FIG. 3). tablets.
After that, the carrier part 491 is moved to the rear side and brought into contact with the upper pedestal part 490 from the front side, so that the carrier part 491 and the upper pedestal part 490 are in contact again (Fig. 37(b)).

While the carrier section 491 transports the first package of tablets, the second package of tablets supplied to the tablet introduction port 480a is carried on the rear side portion of the receiving plate section 500, which is a part of the upper pedestal section 490. It will fall. That is, the second package of tablets is supplied while the carrier section 491 is carrying out the single conveyance operation (the operation of moving only the carrier section 491 forward until it comes into contact with the upper pedestal section 490 again). becomes.
Then, after the carrier part 491 comes into contact with the upper pedestal part 490 again, it moves further to the rear, so that the upper pedestal part 490, which was pressed rearward by the carrier part 491, also moves to the rear side. do. That is, the carrier section 491 and the upper pedestal section 490 move toward the rear side while maintaining the state in which they are in contact with each other.

As a result, the receiving plate section 500 also moves rearward, so that the second package of tablets fed onto the receiving plate section 500 is delivered before the tablet conveying device 474 assumes the first standby posture. falls downward.
That is, the second package of tablets fed onto the lower end side of the first tablet supply hole 480 and above the receiving plate part 500 is transferred to the tablet drop hole as the receiving plate part 500 moves to the rear side. 510 is introduced into the upper opening portion. Then, it falls downward from the first tablet supply hole 480.
Then, according to the same procedure as described above, the second package of tablets stored inside the storage hole 520 in the first standby position is transported. Note that when the third package and subsequent tablets are supplied, that is, when the subsequent tablets are supplied, the same procedure is used to sequentially transport the tablets.

As described above, the tablets supplied to the one-sided tablet receiving section 365a are supplied to the tablet extrusion section 368 via the horizontal conveyance section 366 and the falling path forming section 367, and when the tablets are supplied to the tablet extrusion section 368 after passing through the horizontal conveyance section 366. In some cases, the tablets may be supplied to the tablet extrusion section 368 via the falling path forming section 367 without passing through the falling path forming section 367.
From this, when carrying out the conveyance operation in the tablet extrusion section 368, depending on the prescription, tablets that do not pass through the horizontal conveyance section 366 are supplied to the tablet extrusion section 368, and then tablets that pass through the horizontal conveyance section 366 are fed to the tablet extrusion section 368. The paper waits until it is supplied to the section 368, and then carries out the transport operation.
On the other hand, if all the tablets do not pass through the horizontal conveyance section 366, after the tablets are supplied to the tablet extrusion section 368, such a standby operation is not performed and a conveyance operation is performed.

In the above-described embodiment, an example was shown in which the tablets are pushed and moved by the tablet extrusion piece section 438 in the horizontal conveyance section 366. However, the primary conveyance section of the present invention is not limited to this.
For example, the primary conveyance unit may be equipped with a small conveyor device such as a roller conveyor or a belt conveyor, and the tablets may be conveyed by operating this conveyor device.
Further, instead of the medicine receiving groove portion 410, a receiving portion having an inclined surface inclined toward the discharge port side may be formed at the bottom portion. Further, a mechanism for vibrating the inclined surface may be further provided, and the tablets dropped onto the inclined surface may be moved and transported by vibration.

Therefore, the above-described packaging device with a medicine shelf includes a medicine packaging device that packages and discharges medicines supplied from the outside in single doses, and a medicine shelf device that supplies tablets to the medicine packaging device. In the packaging unit, the medicine shelf device is capable of holding a plurality of tablet containers, and includes a tablet transport device that transports tablets supplied from each tablet container to a predetermined position, and the tablet transport device includes: It includes a primary transport section and a secondary transport section, the primary transport section is a part that transports tablets in a direction intersecting the direction from the medicine shelf device side to the drug packaging device side, and the secondary transport section is , the tablets are transported in a direction from the medicine shelf device side to the drug packaging device side, the tablets being transported by the primary transport section and then transported by the secondary transport section, and the tablets being transported by the primary transport section. It is possible to carry out the operation of carrying the object by the secondary carrying part without carrying it by the carrying part.

The primary conveyance section includes a receiving section for receiving supplied tablets, and a tablet extrusion piece, and the tablet extrusion piece is movable in the tablet conveyance direction in the primary conveyance section. The tablet conveying operation in the primary conveying section is an operation of pushing and moving the tablet located in the receiving section by the tablet pushing piece.

The tablet conveying device further includes an introduction section into which the tablets supplied from the tablet container are introduced, and after the tablets are supplied to the introduction section, the tablets are temporarily stored inside the introduction section. , the tablets are discharged to the primary conveyance section side or the secondary conveyance section side.

The introduction section has a storage space for primarily storing the introduced tablets and a movable receiving member, and the storage space is for discharging the tablets to the primary transportation section side or the secondary transportation section side. Further, the introduction section has a tablet receiving posture in which the movable receiving member moves, so that the discharging port is closed by the movable receiving member; It is possible to switch between a tablet receiving posture and a state in which the tablet is in communication with the outside.

Further, the movable receiving member has a portion that becomes an inclined surface inclined with respect to the horizontal direction when in the tablet receiving posture, and the introduction portion receives the tablet introduced on the inclined surface.

The tablet conveyance device further includes a path forming section, and the path forming section is provided downstream of the introduction section and the primary conveyance section in the conveyance direction, and upstream of the secondary conveyance section in the conveyance direction. and forms a path for supplying the tablets supplied from the introduction section or the primary conveyance section to the secondary conveyance section located on the lower side, and inside the path forming section there is a A regulating member is formed to regulate the direction of movement.

In the above-described embodiment, an example was described in which the medicine packaging transport device 13 was provided to transport the medicine packaging 14 to the removal container 15, but the present invention is not limited to this.
For example, instead of providing the drug package transport device 13, a box-shaped take-out container (not shown) may be placed below the outlet that discharges the drug package 14 from the device main body 2 side to the drug package transfer device 13 side. It may also be a structure in which it is installed.
In this case, a wheel member may be provided on the lower surface of the take-out container (not shown) so that the take-out container can be moved by being pushed by the user's hand.
Furthermore, a structure may be adopted in which the extraction container is attracted to the apparatus main body 2 by attaching a magnetic member formed by a permanent magnet to the side surface of the extraction container and bringing the side surface of the extraction container into close contact with the wall surface of the apparatus main body 2. .

Further, the medicine packaging device 1 is formed with a suction path extending from the vicinity of the scraping cleaning device 43 to a suction device (not shown). Consider a case where a part of this suction path is formed by a resin hose member 575 (see FIGS. 3(b) and 38(b)).
At this time, when the upper lid part 5 is in a closed state (see FIG. 1), a part of the hose member 575 is located above the powder division area 10 (not shown).
Specifically, a portion of the hose member 575 is placed upwardly away from the distribution plate 20 (not shown).

From this, when the operation of supplying powder to the powder injection groove 20a (see FIG. 2) and rotating the distribution plate 20 (powder division operation), the powder that has flown up for some reason will be transferred to the hose member 575. There is a risk of temporary adhesion. If the powder temporarily attached to the hose member 575 falls after a while, it may fall onto the distribution tray 20 during the dividing operation of other powders, causing contamination.

Therefore, as a structure for preventing such contamination, as shown in FIG. A powder medicine shielding plate portion 580 may be formed at a position between the two.
Specifically, this powder shielding plate part 580 has a structure including a support frame part 581 and a shielding plate main body 582, and a shielding plate is attached to a bottom plate part 581a (details will be described later) of the support frame part 581. This is a portion formed by placing the section main body 582.

The support frame part 581 is a frame-shaped part formed to protrude forward from a standing wall-shaped part adjacent to the rear end part of the powdered medicine division area 10, and has a substantially square annular shape in plan view, It has a structure including a bottom plate portion 581a, two side wall portions 581b, and a front wall portion 581c.

The bottom plate portion 581a is a plate-shaped portion whose thickness direction is in the up-down direction. A through hole that penetrates the bottom plate portion 581a in the thickness direction and has a substantially rectangular opening shape is formed in the center of the bottom plate portion 581a.
The two side wall portions 581b and the front wall portion 581c are both vertical wall-shaped portions that protrude upward from the edge portion of the bottom plate portion 581a.

In this way, by placing the powder medicine shielding plate part 580 on the frame-shaped support frame part 581, the work of attaching and detaching the powder medicine shielding plate part 580 becomes easy. Further, since the powder shielding plate portion 580 is located between the hose member 575 and the distribution plate 20, it is possible to prevent powders flying up from the distribution plate 20 from adhering to the hose member 575. Furthermore, even if powders adhere to the hose member 575 for some reason, the powders falling from the hose member 575 can be caught by the shielding plate main body 582, thereby preventing the powders from falling into the distribution tray 20.

Moreover, the scraping cleaning device 43 (see FIG. 3) of the tablet supply unit 11 is not limited to the structure of the embodiment described above. For example, the scraping cleaning device 43 may be unitized to form a tablet supply unit that is detachable from the box. That is, a tablet supply unit (whole illustration is omitted) may be formed that includes a box portion and a cleaning device unit 590 (see FIG. 39).

As shown in FIG. 39(a), the cleaning device unit 590 is formed by housing each part of the cleaning mechanism main body 131 (see FIG. 9) inside a case member 595.
Specifically, the case member 595 is roughly divided into a box-shaped member in which a gear storage section 595a, a brush storage section 595b, and a connecting cylinder section 595c are integrally formed.

The gear storage part 595a is a part that stores a part of the motor 137 and two gears (see FIG. 9) consisting of the motor connection gear 138 and the gear part 140, and the two gears are in a state where they can rotate in conjunction with each other. It is stored.

The brush storage portion 595b is a portion that stores the rotating brush main body 141, and the rotating brush main body 141 is stored in a rotatable state. Note that the shaft portion of the rotating brush main body 141, which is connected to the gear portion 140, is inserted into a vertical partition wall portion 596 located at the boundary between the gear storage portion 595a and the brush storage portion 595b. In other words, the partition wall portion 596 has a through hole through which the shaft portion can be inserted.

The connecting cylinder part 595c has a structure that allows connection of an external cylindrical member such as a hose, and the internal space of the connecting cylinder part 595c is in communication with the internal space of the brush storage part 595b. In other words, in the brush storage portion 595b, a suction opening 597 (see FIG. 39(b)) that is continuous with the internal space of the connecting cylinder portion 595c is formed in a part of the inner peripheral surface.

Here, as shown in FIG. 39(a), the brush storage portion 595b includes the above-mentioned partition wall portion 596 and an outer standing wall portion 598 in the form of a vertical wall, which faces the partition wall portion 596 and is separated from the partition wall portion 596 in the axial direction of the rotating brush body 141. It has a structure including a peripheral wall portion 600.

The peripheral wall portion 600 is a portion located between the partition wall portion 596 and the outer standing wall portion 598. Specifically, as shown in FIG. 39(b), it is a wall-shaped portion divided into an upper wall portion 600a, a standing wall portion 600b, and a lower wall portion 600c, and the rotating brush body 141 has a columnar shape. They are arranged in order along the circumferential direction.

The upper wall portion 600a is a portion that extends in a mountainous manner at a position away from the main body portion of the rotating brush main body 141 upwardly. That is, the front end side portion (the right side in FIG. 39(b)) curves downward as it goes forward, and the rear end side portion (the left side in FIG. 39(b)) curves downward as it goes rearward. It is curved downward.

The vertical wall portion 600b is continuous with the rear end portion of the upper wall portion 600a and extends in the vertical direction.

The lower wall portion 600c is continuous with the lower end portion of the standing wall portion 600b, and includes a plate-shaped portion that extends downwardly from the rear side toward the front side, and a flat plate that extends toward the front side along the front-rear direction. The shaped portion is integrally formed. Further, a folded portion 605 having a shape in which the front end portion is folded upward is formed at the front end portion of the lower wall portion 600c. The folded portion 605 is a wall-shaped portion that projects upward and extends in the axial direction of the main body portion of the rotating brush main body 141.

An opening portion is formed at the front side of the brush storage portion 595b, between the front end portion of the upper wall portion 600a and the front end portion of the lower wall portion 600c, and serves as a boundary between the outside and the internal space of the brush storage portion 595b. ing.

Here, in the peripheral wall part 600, the front part of the upper wall part 600a and the front part of the lower wall part 600c are different from the inner peripheral surface of the rotating brush, compared to the majority of the part located on the rear side of the peripheral wall part 600. The main body 141 is formed so that the distance to the main body portion is long.
That is, when the rotating brush main body 141 is rotated, the inner circumferential surface (inner surface) of the vertical wall portion 600b and the brush bristles (bristle bundle) come into contact, whereas the front side portions of the upper wall portion 600a and the lower wall portion 600c In this case, the inner circumferential surface of the peripheral wall portion 600 and the brush bristles do not come into contact with each other.

Specifically, as shown in FIG. 39(b), the bristles of the rotating brush main body 141 are arranged in the radial direction of the main body in a plan view with the axial direction of the main body of the rotating brush main body 141 as the viewing direction. It is located within the range of an imaginary circle S1 whose center is at the center position and whose radius is L1. Note that L1 is the length from the center position of the main body in the radial direction to the protruding end of the longest brush bristles.

Here, the distance from the center position of the main body part of the rotating brush main body 141 in the radial direction to the inner circumferential surface of the peripheral wall part 600 is different for each part of the peripheral wall part 600.
That is, in both the upper wall portion 600a and the lower wall portion 600c, the distance from the same center position to the inner circumferential surface is longer than L1.
In addition, in the standing wall portion 600b, the distance from the concentric position to the inner circumferential surface (inner surface) of the standing wall portion 600b is shorter than L1.

From this, when the rotating brush main body 141 is rotated in a direction in which the brush bristles approach the front side from above (rotated clockwise in FIG. 39(b)), the brush bristles do not come into contact with the front portion of the lower wall portion 600c. First, it moves so as to cover the rear part of the lower wall portion 600c.
Subsequently, the brush bristles move while coming into contact with the standing wall portion 600b. At this time, the brush bristles are pressed against the vertical wall portion 600b and move upward while the portion around the tip side is bent. In other words, the tips of the brush bristles are rubbed against the vertical wall portion 600b.
Then, the brush bristles move forward without contacting the inner circumferential surface of the upper wall portion 600a.

For this reason, when the rotary brush main body 141 is rotated during a cleaning operation or the like, it is possible to remove powdered medicines attached to the brush bristles. In other words, by moving the brush bristles while making contact with the inner wall portion (vertical wall portion 600b) of the brush storage portion 595b and simultaneously performing a suction operation, it is possible to drop the powder from the brush bristles and suck it.

In addition, as described above, since the folded part 605 is formed on the lower wall 600c, even if the powder that has fallen from the brush bristles cannot be sucked and the powder falls downward, the upper surface of the lower wall 600c It can prevent powder from falling downward. That is, it is possible to prevent the powder from falling from the lower wall portion 600c, which moves downward due to its own weight.

As described above, the medicine inlet 25 for supplying the medicine is formed in the part of the powder division area 10 between the two distribution plates 20 (see FIG. 2). The drug introduction port 25 is formed by attaching an introduction hopper to the placement plate portion 10a.
Here, the introduction hopper may be a hopper member 630 shown in FIG. 40(a).

The hopper member 630 is a powder funnel-shaped member, and like the introduction hopper shown in FIG. 2, the opening area of the introduction side opening located on the upper side is the opening area of the discharge side opening located on the lower side (See FIGS. 2 and 40). Between the introduction side opening and the discharge side opening, there is a space that narrows toward the bottom, and a space surrounded by the peripheral wall is formed, and the introduced powder flows on the inner peripheral surface of the peripheral wall, and the discharge side It has a structure that leads to an opening.

Here, when paying attention to the back side of the hopper member 630, a powder passage hole 633 is formed in the bottom portion of the hopper member 630, which is connected to the discharge side opening. A plane-wide surface is formed around the lower opening (upper side in FIG. 40(a)) of the powder passage hole 633.

Specifically, a mounting protrusion 635 is formed in the lower portion of the hopper member 630, and the outer shape of at least the lower portion thereof is substantially square columnar. The lower end portion of the attachment protrusion 635 is a portion that can be fitted into the powder medicine inlet 636.
The lower opening of the powder passage hole 633 is located at the center of the bottom surface of the attachment protrusion 635 and its periphery. That is, the flat plate portion is located between the outer side surface of the attachment protrusion 635 that contacts the inner peripheral surface of the powder medicine inlet 636 and the lower opening of the powder medicine passage hole 633.

Therefore, even if powders that have fallen downward through the powder passage hole 633 fly up for some reason when the powders are put into the hopper member 630, the attachment can be fixed as shown by the arrow in FIG. 40(b). It becomes possible to make it contact the bottom surface of the projection part 635 and drop it.
That is, unlike a structure in which a gap is formed between the side wall portion of the mounting protrusion 635 and the peripheral portion of the powder passage hole 633, the powder does not get stuck in the gap and the powder is reliably directed downward. It can be dropped. Note that the mounting protrusion 635 may not have a size that allows it to be inserted (fitted) inside the powder medicine introduction port 636, but may have a width (thickness) that makes it impossible to insert it into the powder medicine introduction port 636. That is, the total area of the bottom surface of the mounting protrusion 635 and the opening area of the lower opening of the powder passage hole 633 (the area of the bottom part surrounded by the outer periphery) is larger than the opening area of the powder introduction port 636. It may be formed to be larger. In this case, the peripheral portion of the powder medicine inlet 636 may be brought into contact with the bottom surface of the attachment protrusion 635b, so that the powder medicine passage hole 633 and the powder medicine inlet 636 are communicated with each other.

In the embodiment described above, the flat plate-shaped lock piece forming portion 276c (see FIG. 25) that projects in an oblique direction has been described, but the present invention is not limited to this.
For example, as shown in FIG. 41, a lock forming piece 650 may be formed by bending back the protruding end portion.

This lock forming piece part 650 is formed to have a longer length in the protruding direction than the above-mentioned lock piece forming part 276c, and is curved toward the upstream side of the fixing plate part 276a (left side in FIG. 41(b)). . From this, the upper end portion of the lock forming piece 650 extends diagonally upward (the overall protruding direction of the lock forming piece 650), then extends upstream, and then diagonally downward. It's just a little bit longer.

Therefore, the lock forming piece 650 extends upward from a position adjacent to the upper side of the locking piece insertion hole 283 or a position slightly upwardly away from the locking piece insertion hole 283, and then, A curved surface facing downward is formed. This curved surface is formed at the upper end portion of the lock forming piece portion 650, and is a surface that curves diagonally upward to become convex.

Here, when locking the locking mechanism section 272, as described above, the locking piece forming section 292 is brought close to cover the locking piece forming section 650 from above to form a lock inside the member storage space 313. The upper part of the piece 650 is in a stored state. Then, the latching protrusion 315 is inserted into the latching piece insertion hole 283 to engage them.
At this time, with the structure of the locking piece forming portion 276c described above, the user may think that the locking protrusion 315 has been inserted even though the locking protrusion 315 has not been inserted into the locking piece insertion hole 283, and these There was a possibility that the packaging operation would be carried out in a state where the handles were not engaged.

Therefore, in this embodiment, the lock forming piece 650 has the above shape, and when the locking protrusion 315 is not inserted into the locking piece insertion hole 283, the upper periphery of the lock forming piece 650 is in the member storage space 313. The structure is such that the state in which it is inserted cannot be maintained (it is difficult to maintain).
In other words, if the locking piece forming part 292 is placed over the locking piece 650 and the locking protrusion 315 is not inserted into the locking piece insertion hole 283 but is positioned above the locking piece insertion hole 283, the locking The protrusion 315 comes into contact with a curved surface formed on the upper side of the lock forming piece 650. After the locking protrusion 315 slides on the curved surface, it is placed on the upstream side of the curved surface, as shown in FIG. 41(b). From this, when the user visually observes from above, it becomes possible to immediately determine that the latching protrusion 315 and the latching piece insertion hole 283 are not engaged.

By the way, the packaging device 351 with a medicine shelf described above has a structure in which a control device (not shown) such as a board is built into either or both of the tablet cassette shelf 350 and the medicine packaging device 1.
Then, the external device (mobile phone, PC (personal computer), tablet PC, other dispensing equipment) and the built-in control device are enabled to send and receive data (signals) to and from each other via a communication network, It is now possible to construct a drug provision business support system.
The above-mentioned control device and the above-mentioned devices such as mobile phones, PCs, tablet PCs, etc. have arithmetic means constituted by an arithmetic processing unit such as a CPU, and an information storage means constituted by a storage medium such as a memory or a hard disk. The structure is equipped with Furthermore, the structure includes a signal transmitting/receiving means constituted by an interface circuit or the like for transmitting/receiving data (signals) to/from the outside.

For this reason, for example, when inputting prescription data on an external PC, prescription data (hereinafter simply referred to as prescription data) for use in the packaging device with medicine shelf 351 is created and based on this prescription data. The packaging device 351 with medicine shelf may also be operated.

Furthermore, this prescription data may be created by a user of the packaging device 351 with a medicine shelf, such as a pharmacist, directly inputting data regarding prescriptions into the packaging device 351 with a medicine shelf.

In addition, this prescription data may include information regarding the patient to whom the drug is provided, information identifying the prescribed drug, information regarding the date the drug was provided, information regarding the number of days the drug is taken, and information regarding the timing of taking the drug. . Alternatively, the information may be formed by associating these pieces of information.
Further, the above-mentioned information regarding the patient may include data such as a patient ID, a patient name expressed in kanji or kana characters, date of birth, address, and telephone number.
In addition, the above-mentioned information that specifies the prescribed drug includes the drug ID, drug name, information that specifies the tablet container 360 in which it is stored (cassette number, container ID, etc.), the administration start date (dispensing date), and the number of days of administration. , dosage (amount used), number of packets provided, etc. may also be included. Further, data for specifying the drug provider (institution name, facility name, department name, etc., for example, medical institution name, clinical department name, etc.) may be included.
Furthermore, information specifying whether or not the packaging device with medicine shelf 351 has already performed a packaging operation based on the prescription may be included.
The above-mentioned information regarding the timing of taking the drug is information specifying whether to take the provided medicine in the morning, noon, or night.

Note that information regarding the inventory amount (the amount of tablets accommodated) of each tablet container 360 that can be held in the container attachment part 361 may be stored in the storage means of the packaging device with medicine shelf 351 or an external device. That is, the inventory amount may be calculated and stored based on prescription data each time a packaging operation is performed.

Here, as described above, when supplying tablets from the tablet cassette shelf 350 to the medicine packaging apparatus 1, the packaging device with medicine shelf 351 supplies the tablets from the inside of the tablet container 360 held by the container attachment part 361 to the lower side thereof. The tablets are fed to the tablet feeding device 362 located at (see FIG. 29). Then, the tablets are transported inside the tablet supply device 362 and supplied to the drug packaging device 1 from the tablet extrusion path 484 of the tablet supply device 362 (see FIG. 29).

At this time, in the tablet feeding device 362, as described above, the tablet falling from above is introduced into the tablet receiving portion 365 located on the lower side (see FIG. 30). The tablets are then supplied to the tablet extrusion section 368 via different transport routes depending on the introduction position of the tablets. That is, when a tablet is introduced around the center in the left-right direction, the tablet is supplied to the tablet extrusion section 368 via the falling path forming section 367. On the other hand, when a tablet is introduced into either of the left and right ends, the tablet passes through either of the two left and right horizontal conveyance sections 366 and the falling path forming section 367, and then reaches the tablet extrusion section 368. Supplied.

More specifically, in the upper part of the container attachment part 361, as shown in FIG. 29, the tablet containers 360 are arranged and housed in a matrix. Specifically, 11 rows of tablet containers 360 are formed in which six tablet containers 360 are lined up in the vertical direction, and these rows of tablet containers 360 are arranged side by side in the left-right direction.

As shown in FIG. 42, eleven tablet drop paths 660 (tablet supply paths) corresponding to each row of tablet containers 360 are formed on the back side of the container attachment part 361. That is, the same number of tablet drop paths 660 as the number of rows of tablet containers 360 are formed.
Each tablet fall path 660 is surrounded by a peripheral wall and forms a space extending in the vertical direction, and corresponds to a different row of tablet containers 360, respectively. A path is formed for tablets supplied from one or more tablet containers 360 belonging to the corresponding row of tablet containers 360 to fall.

To explain in detail, for example, the row of tablet containers 360 located on the rightmost side (see FIG. 29) corresponds to the tablet falling path 660k located on the rightmost side (leftmost in FIG. 42). The tablets supplied from the tablet containers 360 belonging to the rightmost column are supplied to the tablet supply device 362 via the tablet falling path 660k located on the rightmost side, no matter which tablet container 360 they are supplied from. . Similarly, the row of tablet containers 360 located second from the right corresponds to the tablet drop path 660j located second from the right, and so on, in a one-to-one correspondence.

Note that the tablet drop paths 660b and 660j located at both ends in the left-right direction are provided with drop regulating portions 662 that regulate the moving direction of the tablets falling therein.
This fall regulating portion 662 is a plate-shaped member that is attached in an inclined position, and its upper surface is an inclined surface that slopes downward from the end side toward the center side in the left-right direction. The fall regulating portion 662 is arranged such that the upper end side portion of the upper surface is located closer to the end portion in the left-right direction. In other words, the fall regulating section 662 is a space located inside or below the tablet falling paths 660b and 660j (a space located below in FIG. 42), and extends diagonally across the space in which the tablet falls. There is.
From this, when a tablet that has fallen down the tablet falling paths 660b, 660j falls onto the fall regulating section 662, the direction of movement thereof is changed and the tablet falls closer to the center in the left-right direction.

The tablets introduced into the tablet feeding device 362 via the tablet falling path 660f located at the center are fed to the tablet extruding section 368 (not shown in FIG. 42) via the falling path forming section 367.
On the other hand, the tablets introduced into the tablet feeding device 362 via any of the plurality of tablet falling paths 660 (tablet falling paths 660a to 660e) located on one side in the left-right direction of the central tablet falling path 660f. is introduced into one horizontal conveyance section 366.
Further, the tablets introduced into the tablet feeding device 362 through any of the plurality of tablet falling paths 660 (tablet falling paths 660g to 660k) located on the other side in the left-right direction of the central tablet falling path 660f are , is introduced into the other lateral conveyance section 366.

Here, inside the lateral conveying section 366, as described above, the tablet that has fallen into any position of the drug receiving groove section 410 is pressed by the tablet pushing piece section 438 (see FIG. 33). In other words, by moving the tablet pushing piece portion 438 from the end side to the center side in the left-right direction, each tablet falling at a different position in the left-right direction is pressed toward the falling path forming portion 367 side.

When performing this pressing operation, the tablet pushing piece portion 438 is positioned at a lower position than the falling position of the tablet supplied from the tablet falling path 660 (tablet falling path 660a or tablet falling path 660k) located at the end side in the left-right direction. , and waits at a position further away from the end in the left-right direction.
To be more specific, in the horizontal conveying section 366 located at one end in the left-right direction (the right side in FIG. 42), the position where the tablets supplied from the tablet falling path 660a located at the one end in the left-right direction is Further, the position on one end side in the left-right direction is set as the reference standby position.
Then, after the tablet is dropped while the tablet pushing piece 438 is waiting at the standard standby position, the tablet pushing piece 438 is moved to the center in the left-right direction so that the tablet can be pressed.
Note that the basic structure of the horizontal conveying section 366 located at the other end in the left-right direction (left side in FIG. 42) is the same as that of the horizontal conveying section 366 located at the one end, so the overlapping details will be explained. The explanation will be omitted.

Here, in the packaging device 351 with medicine shelf (tablet cassette shelf 350) of this embodiment, by operating based on the prescription data as described above, the tablet pushing piece part 438 is placed on standby at a position different from the standard standby position. It is possible to press the tablet after that. This operation will be explained in detail below.

When the medicine shelf-equipped packaging device 351 of this embodiment starts the operation of supplying tablets to the medicine packaging device 1, it performs a container specifying operation to specify the tablet container 360 in which the tablets to be supplied are stored.
That is, based on the prescription data and the data stored in the RFID tag attached to each tablet container 360, the tablet container 360 containing the tablets to be supplied from the plurality of tablet containers 360 arranged in parallel in a matrix is selected. Identify. Furthermore, it is specified in which position of the container attachment part 361 the tablet container 360 in which the tablets to be supplied are stored is located.

Note that in this embodiment, the RFID tag attached to each tablet container 360 stores information for identifying the medicine contained therein (drug name, type, etc.). Then, by referring to the information of this RFID tag, the control device of the packaging device with medicine shelf 351 can identify which tablet is stored in each tablet container 360 stored in the container mounting portion 361. ing.
Here, the information stored in this RFID may be referred to by the control device before starting the container specifying operation, and may be stored in the storage means of the control device. In this case, the container identification operation may be performed based on prescription data and data stored in the control device. In addition, when creating prescription data, the information stored in the RFID is referred to, and the prescribed tablet (tablet name, etc.) is associated with information specifying the tablet container 360 in which this tablet is stored, and both of these are linked. You may also create prescription data that includes: In this case, the container identification operation may be performed by referring only to the prescription data.

Further, based on the result of the container specifying operation, the tablet drop path 660 to be used when supplying tablets to the tablet feeding device 362 is specified, and furthermore, whether or not to use the horizontal conveyance section 366 is specified. That is, it is specified whether or not the horizontal conveyance section 366 is to be used, and if so, which horizontal conveyance section 366 is to be used. In other words, it is specified whether both of the two horizontal conveyance sections 366 are to be used, or if either one is used, which horizontal conveyance section 366 is to be used.

Furthermore, when the horizontal conveying section 366 is used, the tablet falling path 660 located closest to the end in the left-right direction among the tablet falling paths 660 that supplies tablets to the horizontal conveying section 366 to be used is also specified. Ru. In other words, the tablet falling path 660 located most upstream in the moving direction of the tablet extrusion piece portion 438 is specified.
To be more specific, for example, in the horizontal conveying section 366 located on the right side of FIG. 42, the right end side is the upstream side in the movement direction of the tablet extrusion piece section 438 in the extrusion operation, and the left end side is the downstream side. That is, the tablet falling path 660a located on the most upstream side becomes the tablet falling path 660 located on the most end side in the left-right direction.
On the other hand, in the other horizontal conveyance section 366 located on the left side of FIG. 42, the left end side is the upstream side in the moving direction of the tablet extrusion piece section 438, and the right end side is the downstream side. That is, the tablet falling path 660k located on the most upstream side becomes the tablet falling path 660 located on the most end side in the left-right direction. That is, on both sides of the falling path forming part 367, the moving direction of the tablet pushing piece part 438 in the extrusion operation is opposite, and the falling path forming part 367 side from which the tablet is pushed out is the downstream side in the moving direction.

Then, a standby position determining operation is performed to determine the standby position of the tablet pushing piece portion 438 based on the above-mentioned identification result.
For example, as shown in FIG. 42(a), if tablets are to be supplied to the horizontal conveying section 366 from the tablet falling path 660a located at the end side in the left-right direction, the standard standby position is the standby position of the tablet extrusion piece section 438. position.

On the other hand, as shown in FIG. 42(b), the tablets are not supplied from the tablet falling path 660a located at the end side in the left-right direction, and the tablet falling paths 660c and 660e are farther away from the center in the left-right direction. When feeding tablets from the tablet, the standby position of the tablet pushing piece 438 is changed.
That is, of the tablet falling paths 660 through which the tablets supplied to the lateral conveying section 366 pass, the tablet falling path 660c located closest to the end in the left-right direction (upstream in the direction of movement of the tablet extrusion piece section 438) is identified. Ru. The standby position (changed standby position) of the tablet pushing piece 438 is a position that is closer to the end in the left-right direction than the specified tablet falling path 660c and closer to the center in the left-right direction than the standard standby position.
That is, an operation is performed to determine whether or not a tablet is supplied from the tablet falling path 660a located at the end side in the left-right direction, and to determine the standby position of the tablet pusher piece portion 438 based on the result of the determination. . After the tablet pushing piece 438 is placed on standby at the determined standby position, the tablet is pushed and moved.

Here, in the operation of determining the standby position described above, a plurality of changed standby positions may be set.
For example, the change standby position may be a position slightly closer to the end in the left-right direction than each of the tablet drop paths 660b to 660e. In this case, if the one located closest to the end in the left-right direction among the tablet falling paths 660 through which the tablets supplied to the horizontal conveyance section 366 pass is defined as the most upstream flow path, then the left and right The position slightly toward the end in the direction is the change standby position. That is, when the tablet falling path 660e located most centrally in the left-right direction is the most upstream flow path, the change standby position is slightly closer to the end in the left-right direction than the tablet falling path 660e. Similarly, when the tablet falling path 660d located second from the center in the left-right direction is the most upstream flow path, the change standby position is slightly closer to the end in the left-right direction than this tablet falling path 660d, and the third and subsequent The same applies to

On the other hand, only one change standby position may be set.
For example, the change standby position may be a position closer to the end in the left-right direction than the specific tablet falling path 660c. In this case, the case where the above-mentioned most upstream flow path is a specific tablet falling path 660c, and the case where the tablet falling path 660 (tablet falling paths 660d, 660e) located at the center side in the left-right direction from the specific tablet falling path 660c If so, the tablet pushing piece portion 438 waits at the change standby position. On the other hand, when the most upstream flow path is the tablet falling path 660 (tablet falling paths 660a, 660b) located on the end side in the left-right direction from the tablet falling path 660c, the tablet pushing piece portion 438 is at the reference standby position. Wait there.

In this way, only one change standby position or a plurality of change standby positions may be set. That is, if a tablet falls between the standard standby position and the change standby position located closest to the end in the left-right direction from the standard standby position, the rear tablet pushing piece 438 may be held at the standard standby position. . In addition, when the tablet falls downstream of a specific change standby position, the tablet pushing piece 438 is moved at the change standby position located on the most downstream side among the change standby positions located upstream of the tablet dropping position. Just wait.
Further, in the above example, the example in which the drop regulating portions 662 were provided on the tablet falling paths 660b and 660j was described, but the present invention is not limited to this, and the falling regulating portions 662 may be provided on other tablet falling paths 660 as appropriate. That is, the fall regulating section 662 may be provided on any of the tablet falling paths 660, or the falling regulating section 662 may not be provided on any of the tablet falling paths 660. The change standby position may be a position upstream of the vicinity of the lowest end of the fall regulating section 662. Note that the tablet receiving portion 365 may be divided based on the position where the fall regulating portion 662 is provided. That is, the positions where the above-mentioned connecting member arrangement portion 371 and the partition member 372 are formed may be shifted in the left-right direction from the vertically upper side of the fall regulating portion 662.

Furthermore, the tablet conveyance operation accompanied by the above-described standby position determination operation may be performed based on information regarding the timing of taking the tablet in the prescription data.
For example, among the drugs prescribed for a predetermined patient, a medicine to be taken in the morning, a medicine to be taken in the afternoon, and a medicine to be taken in the evening are sequentially packaged using the packaging device 351 with a medicine shelf. When carried out, a tablet conveyance operation accompanied by a standby position determination operation may be performed in each packaging operation. That is, each time a packaging operation for packaging tablets is performed, a tablet transporting operation may be performed accompanied by a standby position determining operation.

On the other hand, when performing a packaging operation for each prescription prescribed to multiple patients, such as packaging a medicine prescribed to one patient and packaging a medicine prescribed to another patient. , the standby position determining operation may be performed only once in an operation targeting one prescription.
In other words, when multiple packaging operations are performed, such as when separately packaging drugs to be taken in the morning, afternoon, and evening in an operation targeting a single prescription, packaging is performed using multiple packaging operations. The above operation of specifying the most upstream channel is performed for all tablets. Then, the standby position of the tablet extrusion piece portion 438 is determined based on the identified most upstream channel. Then, when the packaging operation is performed one after another, the standby position of the tablet pushing piece section 438 before the pushing operation can be set to the same determined position in each operation. In other words, the standby position determining operation may be performed for a plurality of packaging operations, and the tablet conveying operation may be performed multiple times based on the results of the previously executed standby position determining operation.

By the way, as described above, the tablet extrusion unit 368 has a structure in which the tablet conveying device 474 is linearly moved to convey the tablet with the tablet placed inside the storage hole 520 (see FIG. 36). ).
Here, when the tablet conveyance device 474 is moved forward (to the right side in FIG. 36) and the tablet is conveyed to the drug packaging device 1 side, it is preferable to move the tablet conveyance device 474 at high speed and then at low speed. . That is, in order to reliably stop the tablet transport device 474 at a prescribed position, the speed of the tablet transport device 474 after a predetermined period of time has elapsed since the start of movement (the speed of the tablet transport device 474 that has moved by a predetermined distance) is set to a lower speed than when the movement started. It is preferable to do so.

Furthermore, it is preferable to send a temporary stop signal to a drive device (such as a motor) that drives the tablet conveyance device 474.
Specifically, when moving the tablet conveying device 474 forward, the drive device is temporarily stopped during the movement. At this time, the tablet conveying device 474 continues to move due to inertia, so the drive device is driven again at a lower output (so that the tablet conveying device 474 moves at a lower speed) until the tablet conveying device 474 completely stops. Perform the action. This makes it possible to bring the tablet conveyance device 474 to a deceleration state more quickly than when the output of the drive device is simply reduced while the tablet conveyance device 474 is moving.

By the way, as described above, the packaging device 351 with a medicine shelf is capable of supplying a maximum of 66 types of tablets from the tablet container 360 to the drug packaging device 1. The container attachment part 361 has a plurality of individual installation parts, and each individual installation part serves as a part for holding (storing) each tablet container 360. That is, the number of individual installation parts is the same as the number of tablet containers 360 that can be held (66 pieces).

Here, in a pharmacy or the like where the packaging device with medicine shelf 351 is operated, the tablets provided to patients may vary greatly from day to day or from one specific period to another. Therefore, from the viewpoint of efficiently operating the packaging device with medicine shelf 351, it is preferable to change the tablet container 360 held by the container attachment part 361 as appropriate.
Therefore, in the packaging device 351 with medicine shelf of this embodiment, by displaying the recommended cassette screen 670 (recommended container presentation screen) shown in FIG. This can be facilitated.

As shown in FIG. 43, the recommended cassette screen 670 includes an installation status display section 675, a scheduled tablet display section 676, a target data change section 677, a data adjustment button 678, a list display change button 679, and an end button. 680 is displayed on the screen. In other words, the screen displays each of these parts and each button in a visible state at the same time.

In this recommended cassette screen 670, tablets that are likely to be targeted for packaging operation within a specified period that is set in advance or automatically (details will be described later) are listed in a scheduled tablet display section 676. indicate. In detail, for each tablet, information that identifies the tablet (tablet name, drug name) and information about the same tablet (details will be described later) are displayed as a list of related information (one line of data). do. At this time, the scheduled tablet display section 676 displays a list of the same number of tablets (66 in this embodiment) as the number of tablet containers 360 that can be held in the container attachment section 361. Furthermore, among the tablets displayed in the list, those that are not accommodated in the tablet container 360 currently held in the container attachment section 361 are highlighted and displayed (for example, medicine 10 in FIG. 43).
Note that the highlighted display in this embodiment is a display in which the background color is displayed in a different color from the others.

At the same time, the installation status display section 675 displays a diagram schematically showing the current status of the container attachment section 361. This figure is a diagram visually displaying a plurality of individual installation parts of the container attachment part 361, and is a diagram showing the positional relationship of each individual installation part in the whole. That is, this is a diagram showing individual installation parts arranged in a matrix in the container attachment part 361, and rectangular frames indicating the respective individual installation parts are arranged in a matrix. Furthermore, a number (uniquely assigned number) for identifying the attached tablet container 360 is written in each frame.

In the diagram displayed on the installation status display section 675, when each individual installed section satisfies a specific condition, a portion corresponding to the individual installed section that satisfies this condition is highlighted. Specifically, when the individual installation part is in a replaceable state, an uninstalled state, or a small quantity state, the individual installation part is highlighted in a different color.

To explain each condition, being in a "replaceable state" means that a tablet container 360 containing a tablet that is not listed in the scheduled tablet display section 676 is attached to the target individual installation section. state.
Furthermore, the term "unattached state" refers to a state in which the tablet container 360 is not attached to the target individual installation section.
Furthermore, being in a "small quantity state" means that although the tablet container 360 containing the tablets listed in the scheduled tablet display section 676 is attached to the target individual installation section, there will be a shortage of tablets in the future. This is a condition that is expected to occur.
Specifically, the amount of tablets in stock stored in the attached tablet container 360 is lower than the amount used in the packaging operation that is predicted to be performed during the specified period described above.

From the above, the user can determine which tablet container 360 should be attached to which individual installation section and which tablets should be filled in advance by simply comparing the installation status display section 675 and the scheduled tablet display section 676. can be easily understood.

Here, since the packaging device with medicine shelf 351 of this embodiment performs the above-described display operation in the installation status display section 675 and the scheduled tablet display section 676, Perform a usage tablet prediction operation to identify expensive tablets.
This tablet usage prediction operation will be explained in detail below, along with explanations of various buttons.

The predicted operation of the tablets to be used can be roughly divided into data for which there has been a past packaging performance (hereinafter also referred to as packaged data) and data for which a packaging operation has not yet been performed at the time of displaying the recommended cassette screen 670 (hereinafter referred to as unpacked data). (also referred to as comprehensive data). That is, it is possible to perform the process on either packaged data or unpackaged data among the prescription data.
By operating each button of the target data changing unit 677, it is possible to change the target data in the usage tablet prediction operation.

Specifically, by pressing the Do data button 677a, which is one of the two paired buttons, a usage tablet prediction operation is performed for the packaged data. Then, the above-described display operation (hereinafter also referred to as comparison screen display operation) is performed in the installation status display section 675 and the scheduled tablet display section 676.
On the other hand, by pressing the other button, the package monitor button 677b, a usage tablet prediction operation is performed using unpackaged data as a target, and a comparison screen display operation is performed.

Furthermore, by operating the provider specification button 677c to specify the institution, etc., the data targeted by the usage tablet prediction operation can be set to either the prepackaged data or unpackaged data to the prescription issuer ( It is possible to narrow down the search based on institutions, facilities, departments, etc. (hereinafter simply referred to as provider).

In the tablet usage prediction operation, when targeting prepackaged data, the expected date specification operation that specifies the expected day when the tablet will be prescribed to the patient (hereinafter also referred to as the expected date) is performed in advance for all patients. After that, an operation is performed to identify patients whose assumed date falls within the specified period. Then, based on the data associated with the identified patient, tablets that are likely to be subjected to packaging operations within the designated period are identified. When unpackaged data is targeted, the expected date specifying operation is not performed, but the tablets included in the unpacked data and targeted for the packaging operation are identified.

In the expected date specifying operation, the date on which the prescribed tablets will disappear from the patient's hand is calculated for each patient based on the information regarding the administration start date and the number of days of administration of the tablets prescribed to each patient. That is, by adding the number of administration days to the administration start date, the day on which the tablets will disappear from the patient's hands is calculated. Then, the expected date is the same day as the day when the prescribed tablet disappears from the patient's hand, or the day after subtracting a predetermined period from this day (for example, the day before the day when it disappears).

Then, patients whose estimated date is included in the specified period are extracted, and data regarding tablets to be provided on the estimated date to each extracted patient is acquired. More specifically, the type of tablet, dosage, and number of sachets are acquired or calculated.
In addition, when prepackaged data is targeted, it is assumed that the tablets prescribed in the past to each patient will be provided again on the expected date.
From this, tablets with a high possibility of being packaged in a specified period are identified.

Then, based on the result of this tablet usage prediction operation, the above-described comparison screen display operation is performed. That is, the comparison screen display operation is performed based on the acquired information or a value calculated from the acquired information.
In addition, in the comparison screen display operation, when displaying the list on the scheduled tablet display section 676 described above, in addition to the drug name (drug name), the cassette number, the number of appearances, the amount used, and the amount in stock are displayed.

“Cassette No.” is a number assigned to each tablet container 360 that stores each tablet, and uniquely identifies the tablet container 360.
The "number of appearances" is the number of times that the packaging operation that includes the tablet is performed when all the tablets provided within the specified period are packaged for the extracted data.
"Usage" is the total amount provided for each tablet within the specified period for the extracted data.
The “inventory amount” is the amount of each tablet currently stored in the tablet container 360.

At this time, by pressing the list display change button 679, the display of the scheduled tablet display section 676 can be switched. That is, each time the list display change button 679 is pressed, it can be switched between a normal display state and a state where only highlighted items are displayed.

Furthermore, on the recommended cassette screen 670, by operating the data adjustment button 678, it is possible to display a screen for changing the specified period described above and adjusting the target data used in the tablet usage prediction operation. It has become.
In this embodiment, as the data adjustment buttons 678, a current day target change button 678a and an estimated date change button 678b are displayed.

When the current day object change button 678a is pressed, a data adjustment screen 700 (see FIG. 44) is displayed.
As shown in FIG. 44, the data adjustment screen 700 displays a period display section 701, a data display section 702, a carry forward button 703, a date change button 704, a delete button 705, and a return button 706. It's a screen.

The period display section 701 is a section in which a designated period that is automatically set is displayed. The specified period displayed here is the specified period used in the above-mentioned tablet usage prediction operation and comparison screen display operation.

The data display section 702 is a section that displays a list of target data used in the above-mentioned tablet usage prediction operation for each patient. In other words, information that identifies one patient (patient name) and information about this patient (preparation date, expected date, etc.) are listed as one related information (one line of data, also referred to as patient unit data). indicate.
Note that the data displayed on the data display section 702 is the data that corresponds to the conditions specified in the target data change section 677 when the data adjustment button 678 (see FIG. 43) was pressed.

The carryover button 703 is displayed inside and outside the data display section 702, and is displayed as one item of each patient unit data in the data display section 702.
Then, when the carryover button 703 displayed on the data display section 702 is pressed, the items related to the expected date of patient unit data including the carryover button 703 are changed. Note that when one or more patient unit data is specified in the data display section 702 (the check box is checked) and the carryover button 703 displayed outside the data display section 702 is pressed, The same is true.
Specifically, the value of the assumed date belonging to the patient unit data is automatically changed so that it becomes the value after the last day of the designated period displayed on the period display section 701 (in this embodiment, the day after the last day).

The date change button 704 is a button for changing the value of the expected date, similar to the carryover button 703.

A delete button 705 is also displayed inside and outside the data display section 702, respectively.
This button is a button for deleting patient unit data, and by pressing the delete button 705 displayed on the data display section 702, the patient unit data including the delete button 705 is deleted. The same applies when the delete button 705 displayed outside the data display section 702 is pressed with one or more patient unit data specified on the data display section 702.

The return button 706 is a button for ending the display of the data adjustment screen 700 and displaying the recommended cassette screen 670. When this return button 706 is pressed, the operation on the data adjustment screen 700 is reflected, and a usage tablet prediction operation and a comparison screen display operation are performed.

The screen displayed by pressing the expected date change button 678b (see FIG. 43) is a data adjustment screen, except that the specified period can be manually entered in the part corresponding to the period display section 701 (see FIG. 44). Since it is the same as 700, detailed explanation will be omitted.
Note that the data adjustment button 678 may display only one button instead of the two buttons, the current day target change button 678a and the expected date change button 678b. In this case, the period display section 701 of the data adjustment screen 700 may display a screen that allows manual input of the designated period. At this time, the displayed screen may initially display a specified period that is automatically set, and the specified period may be changed by the user's operation.

In addition, in the above example, each screen was displayed on the operation display unit 3, but each of the above screens may be displayed on a display device such as a liquid crystal display that does not have a position input device such as an external display device. May be displayed.
When displaying on a so-called touch panel such as the operation display section 3, the user performs an operation of pressing the button by touching the button part with a finger or an operating instrument such as a touch pen, for example. On the other hand, when displaying on a display device such as a liquid crystal display that does not have a position input device, a structure may be adopted in which a cursor pointer that moves in accordance with the operation of a known input device (such as a mouse) is also displayed. In other words, the structure may be such that the button is pressed by aligning the cursor pointer with the button on the screen and pressing a predetermined button on the input device side. This also applies to the button portion displayed on the display device described below.

As described above, the powder supply device 21 of the drug packaging device 1 has a structure including a supply trough 270 and a vibration device (see FIG. 28). The structure is such that the supply trough 270 vibrates when the vibration device operates.
By the way, when the supply trough 270 is not vibrating during the packaging operation, for example, when the distribution plate 20 is rotating after the supply trough 270 has stopped vibrating, the user may vibrate the supply trough 270. There are cases where you may want to do so. That is, there may be a situation in which the user wants to manually drop the powder into the dispensing tray 20, such as when a small amount of powder remains on the supply trough 270 for some reason and the user finds it.

For this reason, a button part is further displayed on any screen (input screen, operation screen, setting screen, etc.) displayed on the operation display unit 3 or the external computer's display device (display, etc.), and the operation of this button part is It is also possible to use a structure in which the supply trough 270 is vibrated by operating the vibration device. Further, this button portion may be operable only from the time when the supply trough 270 stops vibrating during the packaging operation until the distribution pan 20 stops rotating. In other words, the vibration device may be operated by operating the button portion only when the button portion is operable, and the button portion cannot be operated when the button portion is not operable, or the vibration device may not respond to the operation of the button portion. Further, the operable time may be set as appropriate, and for example, the operation may be appropriately set even in situations other than the above, such as before a cleaning operation.

Here, as shown in FIG. 7, a nozzle-side magnet member 800 is attached to a part of the outer circumferential surface of the proximal end-side cylindrical portion 106 of the distal end nozzle portion 98 described above. This nozzle side magnet member 800 is a member formed of a known permanent magnet.
Furthermore, as shown in FIG. 6, two magnetic sensors 801 are attached to the support section 101 that supports the tip nozzle section 98.
These two magnetic sensors 801 are attached at positions 180 degrees apart in the circumferential direction of the proximal cylinder part 106, and the proximal cylinder part 106 rotates in the space located between the two magnetic sensors 801. It has a structure.

Here, the tip nozzle portion 98 may be removed and reattached after cleaning or the like. In the drug packaging device 1 of this embodiment, when the user attaches the device in a posture different from the prescribed posture (the standby posture or the cleaning posture, in this embodiment, the cleaning posture), the drug packaging device 1 automatically automatically A posture adjustment operation to shift to a specified posture is possible.

Specifically, when the distal nozzle section 98 is not attached in the prescribed posture, the nozzle-side magnet member 800 is at a position shifted in the circumferential direction of the proximal tube section 106 compared to when it is attached in the prescribed posture. can be attached to. From this state, the distal nozzle section 98 is defined by rotating the distal nozzle section 98 until it reaches a position where one of the magnetic sensors 801 described above and the nozzle-side magnet member 800 overlap in the radial direction of the proximal tube section 106. Shift to posture.
This attitude adjustment operation may be carried out on the condition that the upper lid part 5 is shifted to the closed state after the tip nozzle part 98 is attached. Further, the prescribed posture in this posture adjustment operation is not limited to the above-mentioned posture, and may be changed as appropriate.

The drug packaging device 1 of this embodiment can perform various cleaning operations that target the above-mentioned distribution plate 20. That is, it is possible to perform a distribution plate cleaning operation that includes at least one of the cleaning operations that target the distribution plate 20 described above.
Furthermore, the drug packaging device 1 is capable of performing various cleaning operations that target the scraping device 22 described above. That is, it is possible to perform a screw cleaning operation that includes at least one of the cleaning operations that target the scraping device 22 described above.
In addition, the medicine packaging device 1 of the present embodiment is capable of performing a route cleaning operation in which the powder medicine introduction route is targeted for cleaning.

Specifically, in the route cleaning operation, at least a part of this powder introduction route is targeted for cleaning. That is, at least one of the introduction hopper (introduction hopper or hopper member 630 in FIG. 2) forming the medicine introduction port 25 and the member (cylindrical member) forming the powder medicine introduction port 636 is to be cleaned. There may be.
The path cleaning operation may include an operation of applying vibration to the introduction hopper using a vibration member (not shown) disposed near the introduction hopper. Further, the operation may include an operation of sucking the remaining powder medicine adhering to the powder medicine introduction route by operating the above-described suction device.

Here, in the drug packaging device 1 of the present embodiment, after performing the packaging operation, the distribution plate 20 used in the packaging operation, the scraping device 22 associated with this distribution plate 20, and the powder medicine introduction route are connected to each other. A cleaning operation is being performed. That is, a continuous cleaning operation is possible in which the above-described screw cleaning operation, route cleaning operation, and distribution plate cleaning operation are sequentially performed.

Furthermore, in the drug packaging device 1 of this embodiment, when performing the dispensing operation continuously, the execution order of the screw cleaning operation, the route cleaning operation, and the dispensing plate cleaning operation is appropriately changed to perform the continuous cleaning operation. It is possible. This operation will be explained in detail with reference to FIG. 45.

First, when the preceding sapping operation is executed, the prescription data for the next sacheting operation is input before the continuous cleaning operation starts after this sapping operation ends. A determination operation is performed to determine whether or not it has been completed (Step 1). Specifically, it is determined whether this prescription data has been input before the start of the first screw cleaning operation (operation for cleaning the scraping device 22) in the continuous cleaning operation.

Here, if prescription data is not input (No in Step 1), the execution order is not changed (Step 5), and the cleaning operations are performed in the same order as usual: screw cleaning operation, route cleaning operation, and dispensing plate cleaning operation. Execute (Step 6).

On the other hand, if prescription data is input (Yes in Step 1), it is determined whether the previously executed packaging operation is a packaging operation that uses only one distribution pan 20. A determination operation is performed (Step 2).

If a packaging operation that uses only one distribution pan 20 is performed (Yes in Step 2), the subsequent packaging operation uses one of the distribution pans 20 consecutively. It is determined whether or not it is a packaging operation (Step 3).

That is, when a packaging operation using only one of the distribution plates 20 is performed in advance, and then a packaging operation using only the same distribution plate 20 is performed (Yes in Step 2 and Yes in Step 3). case), the execution order of the cleaning operations is changed (Step 4).
On the other hand, when performing a packaging operation using only one of the distribution plates 20, and then performing a packaging operation using only the other distribution plate 20 (Yes in Step 2 and No in Step 3) ), the execution order of the operations is not changed (Step 5).

That is, when one of the distribution plates 20 is used continuously, the cleaning operation is performed to clean the distribution plate 20 in advance so that powder medicine can be quickly supplied to the distribution plate 20 in the subsequent packaging operation. Change the order (Step 4). Specifically, the execution order is changed to include the screw cleaning operation, the distribution plate cleaning operation, and the route cleaning operation (Step 4), and the cleaning operation is performed (Step 6).
On the other hand, when one distribution pan 20 and the other distribution pan 20 are used sequentially, it is preferable to first clean the powder introduction path that will also be used in the subsequent packaging operation, so the order of execution of the cleaning operation is is not changed (Step 5), and the cleaning operation is performed (Step 6).

Note that if the previously executed packaging operation is a packaging operation that uses both distribution plates 20 (No in Step 2), the execution order of the cleaning operations is also changed (Step 4). A cleaning operation is performed (Step 6).
In either case, by carrying out the cleaning operation as described above, the scraping device 22, distribution plate 20, and powder introduction path that were used in the previously executed packaging operation are cleaned.

Further, in the medicine packaging device 1 of this embodiment, the operation of automatically rotating the supply device lid portion 21b of the powder medicine supply device 21 (see FIG. 28) is possible. That is, a drive mechanism such as a motor (not shown) can automatically rotate the supply device cover 21b.
