Then, as shown in FIG. 7B, it extends so as to protrude further downward (outward) from the lower side of the tip nozzle portion 98 (the lower side during the cleaning operation). Each portion of the suction port forming plate portion 110 has a shorter projection length than each portion of the blocking plate portion 109 adjacent to it in the rotation direction of the distribution plate 20 .
In addition, the lower end side portion of the tip side portion 120 is closer to the blocking plate portion 109 than the upper end side portion.

The suction port forming plate portion 110 and the blocking plate portion 109 are continuous at the ends located on the tip side of the tip nozzle portion 98 (the left side in FIG. 7(c)) to form an opening end wall portion 125. ing.
Then, the portion between the blocking plate portion 109 and the suction port forming plate portion 110, which is on the base end side of the tip nozzle portion 98 (right side in FIG. 7C) from the opening end wall portion 125, is cleaned. It is 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 a portion with a relatively wide interval (width) and a relatively narrow portion at each portion in the longitudinal direction of the tip-side hollow body 108 .
Also, the portion extending from the suction port portion 126 to the hollow body internal space 114 also has a relatively large cross-sectional area (a cross-sectional area cut along a plane perpendicular to the longitudinal direction of the tip nozzle portion 98) and a relatively small portion. It has a shape with
That is, the portion extending from the suction port portion 126 to the hollow body internal space 114 has a different shape at each portion in the longitudinal direction of the tip side hollow body 108 (tip nozzle portion 98). On the other hand, the cross-sectional area of the upper portion is larger than that of the lower portion in any portion.

Inside the tip nozzle portion 98, a series of spaces are formed from the suction port portion 126 through the hollow body internal space 114, and the spaces located inside the connection tube portion 105 and the base end side tube portion 106, respectively. there is
This series of spaces is connected to the internal space of the dish upper hose portion 102 (see FIG. 6) and forms part of a series of spaces (upper suction path) extending to a 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 to communicate inside and outside, and a cleaning mechanism located inside the box. It is composed of a main body 131 .
The disc insertion hole 130 is a hole having an opening in a portion of the box body of the tablet supply unit 11 that spans the front wall portion 11a and the bottom wall portion 11b.

Here, an inner partition wall portion 133 is formed on the far side of the opening of the disc insertion hole 130 formed in the front wall portion 11a. The inner partition wall portion 133 is continuous with the inner end portion in the left-right direction of the opening of the disc insertion hole 130 formed in the front wall portion 11a, and has the shape of an upright wall extending outward in the left-right direction toward the back side. part.

A raking plate 31 (see FIG. 13) of the raking device 22 is inserted into a position adjacent to the inner partition wall portion 133, which is on the back side of the opening formed in the front wall portion 11a of the disc insertion hole 130. A plate storage area 134 is formed.

The cleaning mechanism main 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 a drive source rotates, the motor connection gear 138 rotates, and the rotating brush portion 139 rotates accordingly.
The rotating brush portion 139 includes a gear portion 140 and a rotating brush main body 141 (rotating body).

The rotary brush main body 141 is a portion formed by integrally attaching brush bristles (bristle bundles of brush bristles) to part of the side surface of a substantially cylindrical main body. 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 outward.
The brush bristles attached to the rotating brush main body 141 also form a bundle of bristles (brush) by densely gathering a plurality of brush bristles, which are elastic bristles, and the plurality of bristles are attached at different positions. The plurality of tufts of bristles form a scraping contact member that comes into contact with the scraping plate 31 during the cleaning operation. Also, 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 drawing), and its area is about 30% of the total area. Brush bristles (hair tufts) are attached only within the region.
The rotating brush main body 141 is partitioned into two regions, one region and the other region, when the side surface is unfolded, one of which is a region for attaching brush bristles, and the other is a region for attaching brush bristles. The area of is the one where no brush bristles are attached.
The area of the area to which the brush bristles are attached is preferably greater than 0% and 50% or less of the total area, from the viewpoint of preventing the bristles from scattering during operation.
As a modification, there is also a configuration in which bristles are provided densely in one part and bristles are provided in other parts in an extremely small amount.

The medicine packaging device 1 of the present embodiment operates each device (the manual cleaning device 6, the under-plate cleaning device 23, the top-plate cleaning device 24, and the scraping cleaning device 43) constituting the cleaning device group described above. , it is possible to execute the first to fourth cleaning operations.
The first to fourth cleaning operations will be described in detail below.

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 unit 3 and the like to perform the above-described switching operation of the three-way valve and the like as necessary. In the first cleaning operation, the user holds the nozzle portion 55 (see FIG. 1, etc.) of the manual cleaning device 6, and cleans by bringing the suction port 55a close to or in contact with the portion to be cleaned.

The second cleaning operation is a cleaning operation performed by the under-plate cleaning device 23, and the third cleaning operation is a cleaning operation performed by the on-plate cleaning device 24.
These cleaning operations can be automatically executed based on preset conditions. For example, it is possible to automatically perform the packing operation before (or after) the packing operation only when a specific powder medicine is packed. In addition, regardless of the type of powdered medicine, it is also possible to automatically perform the packing operation before or after each packaging operation.
Furthermore, it is possible to start cleaning on condition that the operation display unit 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, among the plurality of (two) distribution trays 20, at least one of the distribution trays 20 is rotated, and the under-plate cleaning device 23 performs a suction operation.
Here, the brush bristles (bristle bundles) 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.
Therefore, by disposing the suction port forming pieces (the first suction port forming piece 80a and the second suction port forming piece 80c) of the under-plate cleaning device 23 below the distribution plate 20, the brush can be applied to the lower surface of the distribution plate 20. At least part of the bristles come into contact with each other in a deformed state.

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

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 moves downward from the standby posture in which the opening of the suction port 126 faces upward (posture in which the suction port faces other than downward, see FIG. 6A). It shifts to the hour posture (see FIG. 6(b)). That is, the tip nozzle portion 98 rotates, and the blocking plate portion 109 rotates together with the suction port forming plate portion 110 .

When the posture is changed, the blocking plate portion 109 rotates together with the suction port forming plate portion 110 . The rotation of the tip nozzle part 98 has the direction of projection of the tip nozzle part 98 as the rotation axis, and one direction around the rotation axis as the rotation direction. In this rotating direction, of the blocking plate portion 109 and the suction port forming plate portion 110 that are arranged in parallel in the circumferential direction of the rotation shaft, the suction port forming plate portion 110 side is the leading side, and the blocking plate portion 109 is the trailing side. It is oriented to the side.

When shifting to the cleaning posture, as shown in FIG. 11, the lower end portion (protruding end portion) of the blocking plate portion 109 comes into contact with the upper surface of the powdered medicine introduction groove 20a.
Here, in the present embodiment, by rotating the tip nozzle portion 98 as described above, it is configured to shift to the suction posture. This structure has the advantage that the powdered medicine is less likely to enter between the lower surface of the blocking plate portion 109 and the upper surface of the powdered medicine introduction groove 20a.

Here, it is assumed that the blocking plate portion 109 is moved vertically downward from above to come into contact with the upper surface of the powdered medicine charging groove 20a. In this case, the lower surface of the blocking plate portion 109 descends from above the small amount of powdered medicine, dust, etc. (hereinafter also simply referred to as dust, etc.) remaining on the upper surface of the powdered medicine introduction groove 20a, and the upper surface of the powdered medicine introduction groove 20a continues. come into contact with As a result, dust or the like is caught between the dam plate portion 109 and the upper surface of the powdered drug introduction groove 20a.
On the other hand, in the present embodiment, the blocking plate portion 109 rotates together with the tip nozzle portion 98, so that the blocking plate portion 109 moves from the downstream side in the rotation direction of the distribution plate 20 toward the position disposed in the cleaning posture. go. At this time, a portion of the blocking plate portion 109 moves to a position arranged in the cleaning posture while maintaining a state of contact with the upper surface of the powdered medicine feeding groove 20a.
In this way, by moving the blocking plate portion 109 in a direction including not only the vertical component but also the circumferential direction component of the powdered medicine feeding groove 20a, it is difficult for dust or the like to enter between the blocking plate portion 109 and the lower surface thereof. are doing.

In the sucking posture, the distal end side portion 115 of the blocking plate portion 109 is fitted into the powdered medicine charging groove 20a. Therefore, the curved surface formed on the lower end side of the tip side portion 115 is brought into a state of being in close contact with the powdered medicine introduction groove 20a.
On the other hand, part of the radially inner edge portion of the powdered medicine feeding groove 20a and the vicinity thereof enter a recessed portion formed on the lower end side of the connecting portion 116 .

In addition, the powdered medicine feeding groove 20a is a concave portion extending circularly in a plan view, and the cross-sectional shape obtained by cutting the cross section perpendicular to the circumferential direction is concave so as to be rounded and convex downward. It has an oval shape. That is, the radially outer edge portion and the radially inner edge portion are arranged at high positions, and a recess is formed therebetween. The edge portions of the powdered medicine feeding groove 20a positioned inside and outside in the radial direction are all continuous in an annular shape in a plan view.
Therefore, the concave portion formed on the lower end side of the connecting portion 116 is a portion which is located at a relatively high position radially inside the powdered medicine feeding groove 20a and which continues in an annular shape. state.

After the dish cleaning device 24 shifts to the suction posture, the operation of rotating the distribution dish 20 is performed. At this time, the direction of rotation 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 indicated by the arrow in FIG. 11(a)). Therefore, the blocking plate portion 109 in the cleaning posture is located downstream of the suction port forming plate portion 110 in the rotation direction of the distribution plate 20 (see FIG. 11B).

As shown in FIG. 12, in the cleaning posture, the lower end of the suction port forming plate portion 110 is positioned higher than the lower end of the blocking plate portion 109, and is in a state of not contacting the upper surface of the powdered medicine feeding groove 20a. ing. Therefore, dust or the like accumulated on the upper surface of the powdered medicine feeding groove 20a is collected on the upstream side of the blocking 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 distal hollow body 108 through the suction port 126 .

Then, in the third cleaning operation of the present embodiment, the dish cleaning device 24 is shifted from the standby attitude to the suction attitude (first operation), and the suction operation is performed while rotating the distribution tray 20 one or more times ( second action). Subsequently, the dish cleaning device 24 is temporarily shifted to the standby posture (third operation), and the distribution dish 20 is rotated by a predetermined angle (fourth operation). Further, the dish cleaning device 24 is shifted to the suction posture again, the suction operation is performed while rotating the distribution plate 20 at a predetermined angle (fifth operation), and then the dish cleaning device 24 is transferred to the standby posture. Let In this manner, the third cleaning operation is an operation that sequentially executes the series of operations.

In the third cleaning operation of the present embodiment, when the distribution tray 20 is rotated in each series of operations, the distribution tray 20 is rotated in the same direction. That is, in a series of operations, the distribution plate 20 does not rotate in the reverse direction. This configuration is preferable from the viewpoint of minimizing scattering of collected dust and the like 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 the present embodiment, the scraping device 22 takes a standby posture in which the scraping plate 31 is positioned upward when the powder medicine dispensing operation is not performed. By taking the standby posture, part of the scraping plate 31 is inserted into the disc insertion hole 130 on the tablet feeding unit 11 side (see FIG. 13).
The fourth cleaning operation is an operation that is performed in this state, and is an operation that rotates both the scraping plate 31 and the rotating brush main body 141 (see FIGS. 9 and 13) of the cleaning mechanism main body 131 .

Specifically, during the cleaning operation, the rotating brush main body 141 is arranged so that its extending direction is the same as the thickness direction of the raking plate 31 . The rotary brush main body 141 is arranged at a position spaced outward 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 tufts) are attached to a portion of the side surface of the rotating brush main body 141 so as to protrude outward. Therefore, when the rotating brush main body 141 is rotated, the brush bristles come into contact with the scraping plate 31 when approaching the scraping plate 31, and come into contact with the scraping plate 31 when moving away from the scraping plate 31. will not be done. In other words, the brush bristles intermittently contact the scraping plate 31 .

Here, the rotation directions of the scraping plate 31 and the cleaning mechanism main body 131 during cleaning may be the same or opposite. That is, both may rotate clockwise or both may rotate counterclockwise also in plan view (plan view in which the viewing direction is 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 by rotating the rotating brush main body 141 while the scraping plate 31 is not rotated. In this case, after the rotating brush body 141 is rotated, the rotation is stopped, the scraping plate 31 is rotated in the circumferential direction in this state, and the rotating 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 plate 31 .

In the above-described embodiment, an example of rotating the distribution plate 20 in the same direction was shown in the second operation and the fourth operation, but the second operation and the fourth operation are not limited to such operations. 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 direction opposite to that in the second operation.
Specifically, when the second operation is performed, fine powdered medicine may remain linearly along the radial direction of the distribution plate 20 between the blocking plate portion 109 and the distribution plate 20 . Conceivable.
Therefore, after the third action, the fourth action of rotating the distribution plate 20 in the direction opposite to the second action may be performed to shift to the suction posture again. Then, when the blocking plate portion 109 is brought into contact with the upper surface of the distribution plate 20 by shifting to the suction posture again, the fifth operation is performed by bringing the blocking plate portion 109 into contact with the upper surface of the distribution plate 20 at a position different from that at the end of the second operation. may

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

Further, in the above-described third cleaning operation, the first operation of shifting the dish cleaning device 24 from the standby posture to the suction posture, and the second operation of executing the suction operation while rotating the distribution plate 20 by one turn or more. carried out. However, each operation executed in the first operation and the second operation, that is, the operation of shifting the dish cleaning device 24 from the standby attitude to the suction attitude, the operation of rotating the distribution tray 20, and the suction operation are performed. The operations do not necessarily have to be performed in this order.
For example, the suction operation may be performed by the on-plate cleaning device 24 first, and then the operation of shifting the on-plate cleaning device 24 to the posture at the time of suction may be performed. At this time, the distribution tray 20 may be rotated before the suction operation is performed, or may be rotated after the suction operation is performed and before the operation to shift to the suction posture. You can rotate it later. In other words, the order in which these three operations are performed may be changed as appropriate, any operation may be performed first, and any of the remaining two operations may be performed second.
Note that the number of rotations of the distribution plate 20 in the second operation may be changed as appropriate. You may rotate only 1/3 of 1 rotation. In other words, the rotation may be less than or equal to one round, and the rotation may be performed by a predetermined amount. Similarly, when the amount of rotation is increased more than one round, the rotation is performed one and a half rounds, or two rounds and two-thirds of one round are rotated. is not limited to integers.

The above-described third cleaning operation (cleaning operation of the distribution tray 20 by the dish cleaning device 24) can also be performed by performing the fourth operation and the fifth operation from the standby state of the dish cleaning device 24. good. That is, after the operation (fourth operation) of rotating the distribution plate 20 by a predetermined angle in the state where the dish cleaning device 24 is in the standby posture, the dish cleaning device 24 is moved to the suction posture, and the distribution is performed. An action of executing the suction action while rotating the plate 20 at a predetermined angle may be employed.
At this time, the directions in which the distribution plate 20 is rotated are the same in each of the fourth operation and the fifth operation. That is, when the distribution tray 20 is rotated clockwise in plan view in the fourth operation, the distribution tray 20 is also rotated clockwise in plan view in the fifth action. Conversely, when 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 under-dish cleaning device 23 described above is arranged between the two distribution trays 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. 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 powdered medicine receiving tray member 147 .

The anti-scattering plate 146 is a vertical plate-shaped member that extends in a curved manner. It's sticking out. At this time, it is preferable to form the scattering prevention plate 146 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 are approximately the same.
The powdered medicine receiving tray member 147 has a bottom plate portion and a side wall portion, and forms a receiving space 148 surrounded by them. That is, the powdered medicine receiving tray member 147 is a bottomed box-like member, and the receiving space 148 is a space that is open at the top and recessed downward. The bottom plate portion of the powdered medicine receiving tray member 147 is curved so as to protrude downward, and its upper surface is concave.

This powdered medicine receiving tray member 147 is formed at a position adjacent to the lower end portion of the anti-scattering plate 146, and is arranged at a position adjacent to the distribution tray 20 side as shown in FIG. 14(b).
A brush body 81 is attached to the receiving space 148, and the brush bristles (bristle tufts) protrude upward. That is, the brush body 81 is attached above the bottom plate portion of the powdered medicine receiving tray member 147 .

The under-dish cleaning device 145 is attached at a position close to the radially outer end of the distribution tray 20, as shown in FIG. 14(b).
At this time, most of the powdered medicine receiving tray member 147 is positioned below the lower surface of the distribution tray 20 . As a result, the bristles (bristle bundles) of the brush body 81 come into contact with the lower surface of the distribution plate 20 from below.
Furthermore, the anti-scattering plate 146 extends along the circumferential direction of the distribution plate 20, and the inner surface of the anti-scattering plate 146 (the surface on the side of the distribution plate 20) and the edge portion of the distribution plate 20 are slightly are closely spaced apart from each other.
In addition, part of the powdered medicine receiving tray member 147 is also positioned below the space formed between the scattering prevention plate 146 and the edge portion of the distribution tray 20 .

In addition, it is preferable that the under-dish cleaning device 145 be attached at a position close to the supply port 282 (details will be described later) of the powder medicine supply device 21 . That is, it is preferable to attach the supply port 282 so as to be positioned inside a portion of the anti-scattering 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 placing 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 platen plate portion 10a and the mounting position thereof can be easily adjusted.

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

In the above-described embodiment, an example in which a plurality of tufts of bristles (brush bristles) are used as the contact body has been shown, but the present invention is not limited to this. For example, an example of adopting a foam such as a reinforced sponge as the contact body is conceivable. Felt, non-woven fabric, etc. may also be used.
However, from the viewpoint of durability during long-term use, cost, and efficient removal of powdered medicine, it is preferable to form the contact member with brush bristles.

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

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

The first conveyer 165 is a belt conveyer 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. It forms a conveying path that goes obliquely downward.
In other words, a conveying path is formed from the portion of the medicine package conveying device 13 that serves as an introduction port for the medicine package 14 (the right end side in FIGS. 15 and 16) to the secondary conveying section 161 .

The second conveyor 166 is a belt conveyor located downstream of the first conveyor 165 . As shown in FIG. 16, the second conveyer 166 is a belt conveyer 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. , forming a conveying path that gently extends obliquely upward. The second transport conveyor 166 forms a transport path from the first transport conveyor 165 side to the secondary transport section 161 . Reference number 169 is a tension roller.

As shown in FIG. 16, the pressing roller portion 167 has a structure including an attachment arm portion 173, a power supply pulley 174, and a connecting roller portion 175 formed by connecting a plurality of rollers. there is

The mounting arm portion 173 is a long plate-like member, and one end side in the extending direction is rotatably mounted to the outer shell member 160a (see FIG. 15), and the other end side is attached to a part of the connecting roller portion 175. mounted against.
More specifically, the one end side of the mounting arm portion 173 in the extending direction can be rotated about the 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 move up and down.
As a result, the connecting roller portion 175, which is connected to the other end of the mounting arm portion 173 in the extending direction, can also be rotated upward from the natural state (state in which no external force is applied). It is possible to rotate downward from this state.

However, a rotation restricting portion 177 is formed on one end side of the attachment arm portion 173 to restrict rotation of the attachment arm portion 173 beyond a certain level.
That is, when the other end side of the mounting arm portion 173 is rotated upward from the arrangement position in the natural state, a part of the one end side of the mounting arm portion 173 comes into contact with the rotation restricting portion 177. rotation is blocked.

The connecting roller portion 175 is a portion formed by connecting a plurality of (three in this embodiment) rollers. The connecting roller portion 175 has a structure including a first pressing roller 180 (pressing roller), a second pressing roller 181 (pressing roller), and a third pressing roller 182 (pressing roller). A first connecting arm 185 and a second connecting arm 186 are provided for connecting a plurality of rollers.

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

The second pressing roller 181 and the third pressing roller 182 are also two roller bodies arranged in series. The two roller main bodies have the same diameter.

Here, the first pressing roller 180 and the second pressing roller 181 are connected via a first connecting arm 185, and one of the first pressing roller 180 and the second pressing roller 181 is positioned above the other. It is possible to move to Therefore, the first pressing roller 180 and the second pressing roller 181 are vertically rotatable with respect to each other while maintaining a state in which the roller bodies are rotated.
Similarly, the second pressing roller 181 and the third pressing roller 182 are connected via a second connecting arm 186, and each maintains a state in which the roller main body portion is rotated, while rotating each other in the vertical direction. It is in a state of freedom.

Further, each of the first pressing roller 180, the second pressing roller 181, and the third pressing roller 182 is provided with a belt winding portion (detailed illustration is omitted) on which a belt member can be wound. One belt member is wound around the belt winding portions of the first pressing roller 180 and the second pressing roller 181, and another belt member is wound around the belt winding portions of the second pressing roller 181 and the third pressing roller 182. belt member is wound around.
That is, the first pressing roller 180 and the second pressing roller 181 are connected so as to be able to transmit power to each other, and the second pressing roller 181 and the third pressing roller 182 are also connected so as to be able to transmit power to each other. .
Therefore, when the roller body belonging to the first pressing roller 180 rotates with the rotation of the power supply pulley 174, the roller bodies belonging to the second pressing roller 181 and the third pressing roller 182 also rotate. It has a structure.

As shown in FIGS. 16 and 17, the transport guide part 168 is arranged near the downstream end of the second transport conveyor 166, and is a member having an inclined surface whose height increases toward the downstream side in the transport direction. It has become. This inclined surface forms part of the conveying surface.
A missing portion 171 is formed on the inclined surface by missing a portion near the upper end, and a portion of a vertical conveying belt member 218 (described in detail later) is placed in this missing portion 171. state.

The secondary transport section 161 is a member that forms a transport 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 transport section 161 , the lid member 211 is rotatably connected to the main body member 210 at one end side in the width direction of the transport path, and the other end side of the lid member 211 can move 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 portion 162 arranged in a substantially vertical posture and a main body side holding portion 215 (holding portion). The conveying surface forming portion 162 is a metal band that reduces friction with the medicine package 14 .
The main-body-side holding portion 215 (holding portion) is located near the end portion of the conveying surface forming portion 162 in the width direction.
The body-side holding portion 215 has an upper pulley 216 and a lower pulley 217 . Both of the two pulleys 216 and 217 are double pulleys, and are provided with two grooves for suspending the belt, and vertical conveying belt members 218 are suspended on each of them.
The vertical conveying belt member 218 is a round belt with a circular cross section. The shape of the vertical conveying belt member 218 is arbitrary, and may be square, triangular, V-belt, or the like. In any case, the vertical conveying belt member 218 is a narrow belt.

The lid member 211 is formed with a lid-side gripping portion 220 (gripping portion) at a position near the end in the width direction of the conveying path. The lid-side holding portion 220 is a portion that forms a pair with the main-body-side holding portion 215 described above, and forms a holding portion together with the main-body-side holding portion 215 .
The lid-side pinching portion 220 is a portion formed by attaching a plurality of roller members 220a (rollers for pinching) to a predetermined area extending in the vertical direction.
All of the plurality of roller members 220a are idle rollers, and are arranged in parallel with a gap 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 transport path. The roller main body is made of an appropriate elastic member such as rubber. That is, it is formed of a member that is elastically deformable but is less deformable than each roller main body portion belonging to the above-described connecting roller portion 175 .

By closing the lid member 211 , each roller member 220 a of the lid-side clamping portion 220 comes into contact with the vertical conveying belt member 218 .
Here, as shown in FIG. 16, the medicine package conveying device 13 has a motor 225 (power generating means) as a power source, and all drive parts are driven by one motor 225 .
That is, the power supplied from the motor 225 causes the rollers belonging to the first conveyer 165, the second conveyer 166, and the pressing roller portion 167 of the primary conveying portion 160, and the vertical conveying belt member 218 of the secondary conveying portion 161 to move. It is driven to rotate.

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

Then, when the second transport conveyor 166 operates, the first roller 166a of the second transport conveyor 166 rotates. As a result, the first interlocking pulley 230 (FIG. 17), which is integrally mounted with the first roller 166a and rotatable on the same rotating shaft, 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 so as to be rotatable about the same rotating shaft as the second roller 165b of the first conveyor 165 described above. As a result, the second roller 165b rotates with the rotation of the second interlocking pulley 231, 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 . A part of the upper part of the belt member running between the second interlocking pulley 231 and the belt supporting pulley 232 is fitted into the groove formed on the side surface of the power supply pulley 174. state and engaged with the power supply pulley 174 .
This belt member rotates the power supply pulley 174 . As the power supply pulley 174 rotates, each roller main body portion belonging to the connecting roller portion 175 rotates.

The medicine package conveying device 13 of this embodiment can make it difficult for the tablets inside to be damaged when the medicine package 14 is conveyed. In addition, it is possible to suppress the occurrence of wrinkles on the surface of the medicine package 14 and clogging of the medicine package 14 during transportation.
First, the medicine package 14, which is an object to be transported, will be described.
In the medicine packaging device 1 of the present embodiment, medicines (tablets and/or powdered medicines) introduced into a medicine introduction port 25 (see FIG. 2) are packaged one by one, and the medicine packages 14 (see FIG. 2) are connected in a belt shape. 18) and can be supplied to the medicine package conveying 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 for storing each dose of medicine, and a non-medication area in which no medicine is stored. It is divided into storage areas 53 .

The non-storage area 53 is a portion formed by sealing the periphery of the storage area 52 by means such as heat-sealing. It has a structure having a vertical seal portion 53b that extends along the length of the seal. 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 medicine package 14 introduced into the medicine package conveying device 13 is placed on the belt member (conveying surface) of the first conveyer 165 at least in part. It is transported downstream.
Then, the portion that was introduced into the medicine package conveying device 13 first is sequentially moved onto the belt member (conveying surface) of the second conveyer 166 .

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

Here, as described above, the first pressing roller 180, the second pressing roller 181, and the third pressing roller 182 are the same (or substantially the same) as the conveyors (the first conveyer 165 and the second conveyer 166). It has a structure that rotates at a speed of That is, the pressing roller not only presses the medicine package 14 downward, but also applies a force to the medicine package 14 toward the downstream side in the conveying direction.
Therefore, compared with the structure in which the pressing roller belonging to the connecting roller portion 175 is idly rotated, the medicine package 14 to be conveyed is less likely to be wrinkled.

Specifically, as described above, the medicine packaging device 1 of this embodiment can pack not only powdered medicine but also tablets.
As described above, the medicine package 14 is divided into the storage area 52 in which the medicine is stored and the non-storage area 53 in which the medicine is not stored. Then, when a plurality of tablets are stored in one storage area 52, there is a possibility that a bulging portion is formed in the storage area 52 depending on how they overlap (see FIG. 19(b)).

If the pressing rollers are configured to idle, the rollers may not rotate normally because they may get caught on the bulging portion of the medicine package 14 or the like.
In this case, since the roller acts as a resistance, the lower portion of the medicine package 14 in contact with the belt member of the second conveyer 166 precedes the upper portion of the medicine package 14 in contact with the roller. , the surface of the medicine package 14 may be wrinkled.
Further, if only the lower portion is advanced, the medicine package 14 cannot maintain its normal posture during normal transportation, and there is a possibility that it will be twisted. Such twisting causes clogging during transportation.

On the other hand, in the medicine packaging device 1 of the present embodiment, each roller belonging to the connecting roller portion 175 is configured to rotate by the supplied power, and one side of the medicine package 14 in the vertical direction is opposed to the other side. It is a structure that makes it difficult to take precedence.
Further, as described above, each roller belonging to the connecting roller portion 175 is attached so as to be vertically rotatable with respect to the other rollers. Each roller moves up and down according to the swelling portion of the body 14 .
That is, each roller moves upward (in a direction away from the upper surface of medicine package 14) according to the size of the bulging portion when the bulging portion of medicine package 14 passes under it. For this reason as well, the rollers are less likely to act as resistance during transport, and wrinkles are less likely to occur in the medicine package 14 .

That is, the present embodiment is not limited to the conveyor consisting of the first conveyor 165 and the second conveyor 166, but also the conveyor and a plurality of rollers (the first pressing roller 180, the second pressing roller 181, and the third pressing roller 182). The structure is such that the medicine package 14 is conveyed by the .
With such a structure, it is possible to efficiently apply a force toward the downstream side in the conveying direction to the medicine package 14, thereby enabling efficient conveying.

Then, when part of the medicine package 14 reaches the downstream end side of the second conveyer 166, the reached part rides on the inclined surface (curved surface) of the conveying guide portion 168, as shown in FIG. state.
At least the vertical seal portion 53 b of the medicine package 14 rides on the conveying guide portion 168 , and the vertical seal portion 53 b comes into contact with the vertical conveying belt member 218 arranged in the missing portion 171 .

Here, when the two vertical conveying belt members 218 are running, a part of the lower ends of the belt members 218 extending in the vertical direction is disposed in the missing portion 171, and always moves upward from the lower side. there is
Therefore, the vertical seal portion 53b that contacts a portion of the two vertical conveying belt members 218 moves upward together with the portion of the two vertical conveying belt members 218. As shown in FIG. Then, it enters between the roller member 220 a and the two vertical conveying belt members 218 .

Here, as described above, when the lid-side clamping portion 220 (see FIG. 17) is closed, the roller member 220a formed in the lid-side clamping portion 220 and the two vertical conveying belt members 218 come into contact with each other. state.
At this time, since the two vertical conveying belt members 218 (in the present embodiment, the roller member 220a is also formed of an elastic member), the medicine package 14 is pushed between them, thereby causing the medicine package 14 to move. enters between them (see FIG. 21).

That is, the vertical seal portion 53b moves upward and reaches the position where the roller member 220a and the two vertical conveying belt members 218 are in contact. Then, the vertical seal portion 53b enters between the roller member 220a and the two vertical conveying belt members 218 while maintaining contact with the two vertical conveying belt members 218. As shown in FIG. After that, the medicine package 14 passes between them and moves upward as it is.
That is, the secondary transport section 161 is a device that transports the medicine package 14 upward while holding the non-storage area 53 between the roller member 220 a and the two vertical transport belt members 218 . More specifically, it is a device that pinches and conveys a plurality of non-storage areas 53 vertically separated from each other.

In this way, according to the structure for sandwiching and conveying the non-storage area 53 of the medicine package 14, the tablet packaged inside the medicine package 14 is sandwiched between the roller member 220a and the vertical conveying belt member 218. It is preferable because it is not damaged. Moreover, it is preferable that the bulging portion formed in the medicine package 14 is not pinched between the roller member 220a and the vertical conveying belt member 218. FIG.
Then, the medicine package 14 conveyed to the upper end side of the secondary conveying portion 161 is supplied from the secondary conveying portion 161 to the take-out container 15 (see FIGS. 15, 21, etc.).

In the above-described embodiment, an example in which a belt conveyor is adopted as the conveyor section is shown, but the present invention is not limited to this, and for example, a roller conveyor formed by combining a drive roller and a driven roller may be used. good too. The conveyor section may be a conveyor operated by the power supplied to the member forming the conveying surface.

In this embodiment, the formed medicine package is divided into a storage area for storing the supplied medicine and a non-storage area adjacent to the edge portion of the storage area. A secondary conveying section forming a part of the drug package is provided, the secondary conveying section has a clamping section that clamps the non-storage area of the medicine package, and the clamping section clamps the non-storage area, The medicine package is conveyed upward.

Further, the secondary conveying portion has a body portion and a lid portion, a part of the clamping portion is formed on one of the body portion and the lid portion, and the other part of the clamping portion is formed on one of the body portion and the lid portion. It is formed on the other of the body portion and the lid portion, and a part of the holding portion is one or a plurality of belt members, and the belt members are made of an elastic material and have a cross-sectional shape of It extends in a circular or cylindrical shape, and another part of said clamping part is one or more clamping rollers, which rotate about an axis extending in a direction intersecting the conveying direction.

Further, the power generating means also powers each of the conveyor section and the clamping section.

As described above, the drug packaging device 1 of this embodiment has a structure including the operation panel 7 (see FIG. 1). The 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, the operation panel 7 is divided into a plurality of areas, and the plurality of areas include areas that function as various buttons when pressed with a finger or the like. ing. Specifically, a start button portion 250, a stop button portion 251, a set plate open/close button portion 252, and a tablet supply start button portion 253 are formed as regions having functions as operation buttons. A remaining number display section 254 for displaying the remaining number of packages and two speed change sections 255 are also provided.

The start button portion 250 is an area that is pressed to start the medicine packaging operation. The stop button portion 251 is an area to be pressed when it becomes necessary to stop the packaging operation that is being executed for some reason.
The set plate opening/closing button portion 252 is an area to be pressed when opening/closing a predetermined portion of the tablet manual distribution portion 40 (see FIG. 1) of the tablet supply unit 11 .
The tablet supply start button portion 253 is a portion that is pressed when starting a packaging operation for tablets.

The two speed changers 255 correspond to different powdered medicine feeders 21 (see FIG. 2, which will be described later in detail). The speed changing unit 255 serves both as a part that indicates the current supply speed (amount of vibration) and a part that changes the supply speed when powdered medicine is supplied from the powdered medicine supply device 21 to the distribution tray 20. is.

More specifically, the speed changer 255 is a portion that displays the supply speed using a bar graph. That is, a plurality of rod-shaped portions arranged in parallel at intervals are displayed, and as the supply speed increases, the display color of each rod-shaped portion changes from one end side to the other end side in the parallel direction. there is
For example, when the powdered medicine supply operation is not performed, the display color of all the rod-shaped portions is displayed in the normal color (first color). Furthermore, when the supply speed is made the slowest, only one rod-shaped portion located on one end side 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, display is performed such that all the bar-shaped portions are displayed in the changed color.

When changing the supply speed, as shown in FIG. 22(a), the speed can be changed by moving a finger or the like in the parallel direction while touching the speed changing portion 255. As shown in FIG.
That is, by moving a finger or the like from one end side toward the other end side in the parallel direction of the bar-shaped portions, the supply speed increases as the finger or the like moves, and by moving the finger or the like in the opposite direction, the finger or the like increases. The feed speed decreases along with the movement.

As another speed changing operation, as shown in FIG. 22(b), the speed can be changed by performing a short-time touching operation with a finger or the like once or more times.
If the feed speed is neither the maximum nor the minimum, the part that indicates the current speed is set as the reference position, and by touching the position that is on the one end side in the parallel direction of the rod-shaped portion from the reference position, the current speed is specified. slows down by the value. Conversely, when the position on the other end is touched, the speed increases from the current speed by a specified value (Fig. 22(b) shows a speed increase operation).

Also, when the supply speed is the minimum, the rod-shaped portion (or its vicinity) located on the most one end side in the parallel direction of the rod-shaped portions is set as a reference position, and the part on the other end side of the reference position is touched with a finger or the like. As a result, the speed will increase from the current speed by the specified value.
Note that when a finger or the like touches a position away from the reference position to the opposite side (a position farther to one end in the parallel direction of the bar-shaped portions), the speed does not change.

In addition, when the supply speed is the maximum, the rod-shaped portion located on the other end side in the parallel direction of the rod-shaped portions (or its vicinity) is set as a reference position, and the portion on the one end side of the reference position is touched with a finger or the like. This will reduce the current speed by the specified value.
Similarly, when a finger or the like touches a position away from the reference position to the opposite side (a position farther to the other end in the parallel direction of the bar-shaped portions), the speed does not change.
As described above, the speed changing unit 255 of this embodiment is capable of two speed changing operations, and the user can select and execute an appropriate speed changing operation.

That is, it is possible to read information stored in an RFID tag attached to a container (not shown, hereinafter simply referred to as a container for transport) for transporting powdered medicine such as a weighing dish.

Here, information readers 263 are individually attached to the two hopper placement areas 260 (the hopper placement areas 260 positioned inside the small lid portions 5b and 5c).
Since the two hopper arrangement areas 260 correspond to different powdered medicine supply devices 21 respectively, the powdered medicine put into the hopper 261 of one hopper arrangement area 260 is dispensed from one of the powdered medicine supply devices 21. It is supplied to the plate 20 (details will be described later). Also, the powdered medicine put into the hopper 261 of the other hopper arrangement area 260 is supplied from the other powdered medicine supply device 21 to the other distribution tray 20 .

Therefore, when a predetermined powdered medicine contained in a transportation container is put into one of the hoppers 261, by bringing the transportation container close to the information reader 263, the information stored in the RFID tag of the transportation container can be read. Read operation is possible.
By this information reading operation, it is possible to read information about the powdered medicine contained in the transportation container, and a determination operation is performed to determine whether or not the distribution tray 20 to which the predetermined powdered medicine is to be supplied is correct. It is possible.

Although it is not particularly limited, if the dispensing tray 20 to which the powdered medicine is to be supplied is not correct after the determination operation is performed, a notification operation to notify that effect may be performed.
This notification operation may be an operation of displaying a message or an image on the operation display unit 3, an operation of providing a speaker device or the like to play a sound, or an operation of carrying out both of these. may

In addition, by storing the information about the packaging operation using the contained powdered medicine in the RFID tag of the transport container, it is possible to obtain the information about the packaging operation that has not yet been performed by the information reading operation.
Therefore, after the information reading operation is performed, the distribution tray 20 to which the powdered medicine is to be supplied and the equipment that operates when the dispensing operation is performed with this distribution tray 20 are shifted to the standby state before the packaging operation is performed. may be implemented. For example, the operation display unit 3 may display prescription information for starting the packaging operation and information indicating that the information reader 263 has acquired an operation instruction for the distribution tray 20 corresponding to the information reader 263 . Then, when each device is in a standby state, these devices may perform a preliminary operation before performing the packaging operation, if necessary.
Further, after the information reading operation is performed, the cleaning operation (the cleaning operation described above) is performed for the distribution tray 20 to which the powdered medicine is to be supplied and the scraping device 22 associated with the distribution tray 20. may

In this embodiment, the information reader 263 is provided on one of the side walls 260b adjacent to the hopper arrangement area 260. good.
Further, although the side wall portion 260b is provided with the information reader 263 and the transportation container is provided with the RFID tag, the side wall portion 260b may be provided with the RFID tag and the transportation container may be provided with the information reader. That is, the information reader 263 may be provided on either the portion adjacent to the hopper arrangement area 260 or the container for transportation, 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 medicine supply device 21 (see FIG. 2) is positioned below them.

As shown in FIG. 26(b), the lock mechanism portion 272 includes an attachment piece forming portion 290 (second structure), an intermediate connecting portion 291 (connecting body), and a hooking piece forming portion 292 (first structure). body). The locking mechanism portion 272 is rotatably fixed between the mounting piece forming portion 290 (second structure) and the intermediate connecting portion 291 (connecting body). are also axle-mounted.
The locking mechanism portion 272 is a toggle mechanism that links the intermediate connecting portion 291 and the hooking piece forming portion 292. When the intermediate connecting portion 291 is rotated as shown in FIG. Move by being boosted.
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 portion 301 is attached so as to be movable in the front-rear direction, and when the sliding piece portion 301 moves forward, the sliding piece portion 301 is always urged rearward by the spring member 302 . It has a structure that

The hooking piece forming portion 292 is a box-shaped portion that is open on the rear side and the bottom side, and a member storage space 313 (storage space) is formed in the inside thereof (on the 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 that is surrounded from above, from the front, and from both ends in the left and right directions.
Further, a hooking protrusion 315 is formed on the front side of the hooking piece forming portion 292 .
The locking projection 315 is a portion formed at the lower end of the vertical wall-shaped portion located in front of the locking piece forming portion 292, and at least a portion of the locking projection 315 is a projection that protrudes rearward.

A procedure for attaching the supply trough 270 to the tray mounting portion 271 will be described.
In this embodiment, an engagement structure portion 278 is configured by the lock mechanism portion 272 (first main body side engagement portion) and the hooking piece insertion hole 283 (first trough side engagement portion).
As shown in FIG. 26(a), the hooking piece 276b is inserted through the hooking hole 284 from above. Then, the supply trough 270 is moved rearward, and the hooking piece 276b is hooked to the edge portion of the hooking hole 284. As shown in FIG.
In this state, as shown in FIG. 27(a), the hooking piece forming portion 292 is moved toward the fixing member 276, and as shown in FIG. The formation portion 292 is brought close to the lock piece formation portion 276c from above, and the locking projection 315 is engaged with the lock piece formation portion 276c.
Then, as shown in FIG. 27(c), the latching 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)). .

In the engagement posture, the hooking piece forming portion 292 is moved slightly forward (upward in the tilt direction of the mechanism mounting plate portion 271b) compared to the standby posture described above (see FIG. 26(a), etc.). It has become.
In this state, the hooking piece forming portion 292 is always biased rearward. That is, the hooking piece forming portion 292 is always biased downward and rearward when the hooking projection 315 is inserted into the hooking piece insertion hole 283 . In this manner, the supply trough 270 is locked by shifting the lock mechanism portion 272 to the engagement posture.
As described above, in the powdered medicine supply device 21 of the present embodiment, as shown in FIG. ing. Furthermore, the hooking piece 276b and the hooking hole 284 form another engaging portion (second engaging portion). In this manner, the supply trough 270 is engaged with members on the supply 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 portion 272 assumes the engaged posture and the supply trough 270 enters the locked state, the engaging protrusion 315 which is part of one engaging portion and the engaging portion which is part of the other engaging portion are engaged. The stopping piece 276b is always urged in a direction opposite to the direction of movement when releasing the engagement.
That is, since the hooking piece forming portion 292 is biased in a direction opposite to the direction in which it is moved when the engagement is released, the force applied from the hooking piece forming portion 292 causes the supply trough 270 to move. The whole is also in a state of being constantly pulled downward on the upstream side (left side in FIG. 27(c)).
This makes it possible to firmly attach the supply trough 270 to the tray mounting portion 271 . In other words, it has a structure that can maintain the attached state without being accidentally detached even when subjected to vibration. By making the supply trough 270 and the tray mounting portion 271 separate and detachable, the supply trough 270 can be easily cleaned.

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

Here, as shown in FIG. 25, the rear surface of the fixing plate portion 276a, that is, the portion that becomes the lower surface when the saucer mounting portion 271 is attached (see FIG. 26), has an outer (downward when attached) portion. A protruding portion 286 is provided to protrude.
Therefore, when the supply trough 270 is attached to the tray mounting portion 271, a gap is formed between the lower surface of the fixing plate portion 276a and the upper surface of the mounting table forming plate portion 271a at least around the projection portion 286. The Rukoto.
By adopting a structure in which the lower surface of the fixing plate portion 276a and the upper surface of the mounting table forming plate portion 271a are not in contact with each other over the entire area, the generation of noise when the supply trough 270 is vibrated can be suppressed. Also, even if a small foreign object enters between the fixed plate portion 276a and the mounting table forming plate portion 271a when the supply trough 270 is attached, the foreign object may be firmly sandwiched by these parts when the supply trough 270 vibrates. It can be a non-maintained structure. In other words, it is possible to prevent a change in vibration (adverse effect on vibrating with prescribed vibration) caused by vibrating while a foreign object is firmly sandwiched.

Further, in the powdered medicine supply device 21 of the present embodiment, a vibrating device is disposed inside the supply device lid portion 21b, and has a structure in which vibration is transmitted from the supply device lid portion 21b to the hopper 261. FIG.

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 projecting portion projecting outward from the side surface of the hopper 261). That is, it is a portion that regulates the movement of the hopper 261 toward the supply port portion 282 (movement in the direction including the longitudinal component of the supply trough 270 at the time of installation).

The second movement restricting portion 296 is a rod-shaped member formed to protrude outward from the surface of the supply device lid portion 21b on the supply port portion 282 side in a state where the supply trough 270 is attached and the supply device lid portion 21b is closed. part. Specifically, a portion of the distal end side is a bar-shaped portion that is bent downward.
More specifically, the two second movement restricting portions 296 are arranged in parallel so as to face each other in a direction intersecting (perpendicular to) the flow direction of the powdered medicine, each extending toward the supply port portion 282 side. there is The structure is such that the hopper 261 is attached between the two second movement restricting portions 296, and when the hoppers 261 are attached, the respective second movement restricting portions 296 come into contact with different side surfaces of the hoppers 261. It has a structure.
That is, the second movement restricting portion 296 is a portion that restricts the movement of the hopper 261 in the direction including the width direction component of the supply trough 270 .

Here, when the supply trough 270 is attached and the supply device lid portion 21b is closed, neither of the two second movement restricting portions 296 overlaps the supply trough 270 in plan view (the supply trough in the vertical direction). 270).
Therefore, even if the powdered medicine dropped from above stays above the second movement restricting part 296, the powdered medicine on the second movement restricting part 296 does not fall into the supply trough 270. there is

That is, the second tablet supplied onto the receiving plate portion 500 at the inner lower end side of the first tablet feeding hole 480 is moved backward, so that the tablet dropping hole It is introduced into the upper opening of 510 . Then, it drops downward from the first tablet supply hole 480 .
Then, by the same procedure as described above, the second pack of tablets stored inside the storage hole 520 in the first standby posture is conveyed. When the third and subsequent tablets are supplied, that is, when the succeeding tablets are supplied, the same procedure is followed to sequentially convey the tablets.

As described above, the tablets supplied to the one-side tablet receiving portion 365a pass through the horizontal conveying portion 366 and the drop path forming portion 367 and are supplied to the tablet extruding portion 368. In some cases, the tablets are supplied to the tablet extruding section 368 via the drop path forming section 367 without being carried out.
For this reason, when carrying out the conveying operation in the tablet pushing section 368, depending on the prescription, after the tablets that do not pass the horizontal conveying section 366 are supplied to the tablet pushing section 368, the tablets that pass through the horizontal conveying section 366 are extruded. It waits until it is supplied to the unit 368, and carries out the transport operation.
On the other hand, if none of the tablets pass through the horizontal conveying section 366, after the tablets are supplied to the tablet extruding section 368, the conveying operation is performed without performing such a waiting operation.

In the above-described embodiment, an example in which the tablets are pushed and moved by the tablet push-out pieces 438 in the horizontal conveying section 366 is shown. However, the primary transport section of the present invention is not limited to this.
For example, a primary conveying unit having a small conveyor device such as a roller conveyor or a belt conveyor may be used, and the tablets may be conveyed by operating this conveyor device.
Further, instead of the drug receiving groove 410, a receiving portion having an inclined surface that slopes toward the discharge port side may be formed on the bottom portion. Further, a mechanism for vibrating the inclined surface may be further provided, and a structure may be adopted in which the tablets dropped on the inclined surface are moved by vibration and conveyed.

Therefore, the medicine shelf-equipped packaging apparatus described above is provided with a medicine packaging apparatus for packaging and ejecting each dose of medicine supplied from the outside, and a medicine shelf apparatus for supplying tablets to the medicine packaging apparatus. In the packaging unit, the medicine cabinet device has a tablet conveying device capable of holding a plurality of tablet containers and conveying tablets supplied from each tablet container to a predetermined position, wherein the tablet conveying device comprises: A primary conveying section and a secondary conveying section are provided, wherein the primary conveying section conveys tablets in a direction intersecting the direction from the medicine cabinet side to the drug packaging device side, and the secondary conveying section includes an operation of conveying the tablets in the direction from the medicine cabinet side to the medicine packaging apparatus side, wherein the tablets are conveyed by the primary conveying section and then conveyed by the secondary conveying section; It is possible to carry out the operation of conveying by the secondary conveying unit without conveying by the conveying unit.

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

The tablet conveying device further has 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 accommodated in the introduction section. , to discharge the tablets to the primary conveying section side or the secondary conveying section side.

The introduction part 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 transport part side or the secondary transport part side. Further, the introduction part has a tablet receiving posture in which the ejection port is closed by the movable receiving member by moving the movable receiving member, and the ejection port is in a tablet receiving posture. It is possible to switch between a tablet receiving posture in which communication with the outside is achieved.

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

Further, the tablet conveying device further has a path forming section, the path forming section is downstream of the introduction section and the primary conveying section in the conveying direction, and is provided upstream of the secondary conveying section in the conveying direction. and forms a path for supplying the tablets supplied from the introduction part or the primary transport part to the secondary transport part located below, and the path forming part has a tablet tablet inside the path forming part. A restricting member is formed to restrict the moving direction.

In the above-described embodiment, an example in which the medicine package conveying device 13 that conveys the medicine package 14 to the take-out container 15 is provided has been described, but the present invention is not limited to this.
For example, without providing the medicine package conveying device 13, a box-shaped take-out container (not shown) is placed below the discharge port for discharging the medicine package 14 from the apparatus main body 2 side to the medicine package conveying device 13 side. It is good also as a structure to install.
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 manually pushed by the user.
Further, a magnet member formed by a permanent magnet may be attached to the side surface of the take-out container, and the side surface of the take-out container and the wall surface of the device main body 2 may be brought into close contact with each other so that the take-out container is attracted to the device main body 2. .

Further, the drug packaging device 1 is formed with a suction path extending from the periphery of the scraping cleaning device 43 to a suction device (not shown). Consider a case where 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 portion 5 is closed (see FIG. 1), a portion of the hose member 575 is positioned above the powdered medicine dividing region 10 (not shown).
Specifically, a portion of the hose member 575 is arranged at a position spaced apart from the distribution plate 20 (not shown).

Therefore, when powdered medicine is supplied to the powdered medicine feeding groove 20a (see FIG. 2) and the operation of rotating the distribution tray 20 (dividing operation of the powdered medicine) is performed, the powdered medicine that has risen up for some reason is transferred to the hose member 575. It may adhere temporarily. If the powdered medicine temporarily adhered to the hose member 575 falls after a while, it may fall onto the distribution tray 20 during the dividing operation of other powdered medicines, resulting in contamination.

Therefore, as a structure for preventing such contamination, as shown in FIG. A powdered medicine shielding plate portion 580 may be formed at a position between .
Specifically, the powdered medicine shielding plate portion 580 has a structure including a supporting frame portion 581 and a shielding plate portion main body 582, and a shielding plate is attached to a bottom plate portion 581a (described later in detail) of the supporting frame portion 581. It is a portion formed by placing the main body 582 thereon.

The support frame portion 581 is a frame-shaped portion formed so as to protrude forward from the standing wall-shaped portion adjacent to the rear end portion of the powdered drug division region 10, and is a portion having a substantially quadrangular 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-like portion whose thickness direction is the vertical direction. At the center of the bottom plate portion 581a, there is formed a through hole that penetrates the bottom plate portion 581a in the thickness direction and has a substantially square opening shape.
Both of the two side wall portions 581b and the front wall portion 581c are standing wall-like portions protruding upward from the edge portion of the bottom plate portion 581a.

By placing the powdered medicine shielding plate portion 580 on the frame-shaped support frame portion 581 in this way, the work of attaching and detaching the powdered medicine shielding plate portion 580 is facilitated. Moreover, since the powdered medicine shielding plate portion 580 is positioned between the hose member 575 and the distribution plate 20 , it is possible to prevent the powdered medicine flying up from the distribution plate 20 from adhering to the hose member 575 . Further, even if the powdered medicine adheres to the hose member 575 for some reason, the powdered medicine dropping from the hose member 575 can be received by the shielding plate part main body 582, so that the powdered medicine can be prevented from falling to the distribution tray 20.例文帳に追加

Further, the scraping cleaning device 43 (see FIG. 3) of the tablet feeding 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 having a structure detachable from the box. That is, a tablet supply unit (not shown in its entirety) including a box body and a cleaning device unit 590 (see FIG. 39) may be formed.

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

The gear housing part 595a is a part for housing 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 interlocked and rotatable. are housed.

The brush housing portion 595b is a portion for housing the rotating brush body 141, and the rotating brush body 141 is housed in a rotatable state. The shaft portion of the rotating brush main body 141, which is connected to the gear portion 140, is inserted through an upright wall-like partition portion 596 located at the boundary between the gear housing portion 595a and the brush housing portion 595b. That is, the partition wall portion 596 is formed with a through hole through which the shaft portion can be inserted.

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

Here, as shown in FIG. 39(a), the brush housing portion 595b includes the above-described partition wall portion 596 and an upright wall portion 598 facing the partition wall portion 596 in the axial direction of the rotary brush main body 141 with a gap therebetween. , and 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-like portion partitioned by an upper wall portion 600a, a vertical wall portion 600b, and a lower wall portion 600c, and the rotating brush body 141 has a cylindrical shape. They are arranged in order along the circumferential direction.

The upper wall portion 600a is a portion extending like a mountain at a position spaced upward from the main body portion of the rotating brush main body 141 . That is, the front end portion (the right side in FIG. 39(b)) is curved downward toward the front, and the rear end portion (the left side in FIG. 39(b)) is curved toward the rear. It is curved downwards.

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

The lower wall portion 600c is continuous with the lower end portion of the standing wall portion 600b, and extends from the rear side toward the front side so as to slope down toward the front side. The shaped portion is integrally formed. 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 protrudes upward and extends in the axial direction of the body portion of the rotating brush body 141 .

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

Here, in the peripheral wall portion 600, the front portion of the upper wall portion 600a and the front portion of the lower wall portion 600c are more likely to rotate from the inner peripheral surface than the rear portion of the peripheral wall portion 600 located on the rear side. It is formed so that the distance to the main body of the main body 141 is long.
That is, when the rotating brush main body 141 is rotated, the inner peripheral surface (inner surface) of the standing wall portion 600b and the brush bristles (bristle bundles) come into contact with each other, whereas the front side portions of the upper wall portion 600a and the lower wall portion 600c are in contact with each other. , the inner peripheral surface of the peripheral wall portion 600 and the brush bristles do not come into contact with each other.

Specifically, as shown in FIG. 39B, the brush bristles of the rotating brush 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 line of sight. is located within the range of an imaginary circle S1 whose center is the center position in and whose radius is L1. Note that L1 is the length from the center position in the radial direction of the main body to the projecting end of the longest bristle.

Here, the distance from the center position in the radial direction of the main body portion of the rotating brush main body 141 to the inner peripheral surface of the peripheral wall portion 600 differs in each portion of the peripheral wall portion 600 .
That is, both the upper wall portion 600a and the lower wall portion 600c have a distance longer than L1 from the center position to the inner peripheral surface.
Also, in the vertical wall portion 600b, the distance from the center position to the inner peripheral surface (inner surface) of the vertical wall portion 600b is shorter than L1.

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

As a result, when the rotating brush main body 141 is rotated in a cleaning operation or the like, it is possible to remove the powdered medicine adhering to the brush bristles. In other words, by moving the brush bristles in contact with the inner wall portion (upright wall portion 600b) of the brush housing portion 595b and performing a suction operation at the same time, the powdered medicine can be dropped from the brush bristles and sucked.

Further, as described above, since the folded portion 605 is formed on the lower wall portion 600c, even if the powdered medicine dropped from the brush bristles cannot be sucked, even if the powdered medicine falls downward, It is possible to prevent powder medicine from falling downward. In other words, it is possible to prevent the powdered medicine, which moves downward due to its own weight, from falling from the lower wall portion 600c.

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

The hopper member 630 is a substantially powder funnel-shaped member, and similar to the introduction hopper shown in FIG. (see FIGS. 2 and 40). Between the introduction side opening and the discharge side opening, there is formed a space that narrows toward the lower side and is surrounded by the peripheral wall. It has a structure that leads to the opening.

Here, focusing on the back side of the hopper member 630, the bottom portion of the hopper member 630 is formed with a powdered medicine passage hole 633 connected to the discharge side opening. Around the lower opening (the upper side in FIG. 40(a)) of the powdered medicine passage hole 633, a planarly expanding surface is formed.

More specifically, the lower portion of the hopper member 630 is formed with a mounting projection 635 having at least the outer shape of the lower portion in a substantially quadrangular prism shape. The mounting protrusion 635 has a lower end portion that can be fitted into the powdered medicine introduction port 636 .
The lower opening of the powdered medicine passage hole 633 is positioned at the central portion of the bottom surface of the mounting protrusion 635 and its periphery. That is, the flat plate portion is located between the outer side surface of the mounting projection 635 that contacts the inner peripheral surface of the powdered medicine introduction port 636 and the lower opening of the powdered medicine passage hole 633 .

For this reason, when powdered medicine is thrown into the hopper member 630, even if the powdered medicine that has fallen downward through the powdered medicine passage hole 633 rises up for some reason, as indicated by the arrow in FIG. It is possible to contact the bottom surface of the protrusion 635 and drop it.
That is, unlike the structure in which a gap is formed between the side wall portion of the attachment protrusion 635 and the peripheral portion of the powdered medicine passage hole 633, the powdered medicine does not get stuck in the gap, and the powdered medicine is reliably pushed downward. can be dropped. The mounting protrusion 635 may not have a size that allows insertion (insertion) into the powdered medicine introduction port 636 , but may have a width (thickness) that does not allow insertion into the powdered medicine introduction port 636 . That is, the sum of the area of the bottom surface of the mounting protrusion 635 and the opening area of the lower opening of the powdered drug passage hole 633 (the area of the portion surrounded by the outer periphery at the bottom portion) is larger than the opening area of the powdered drug introduction port 636. It may be formed to be large. In this case, the peripheral portion of the powdered medicine introduction port 636 may be brought into contact with the bottom surface of the mounting protrusion 635b to allow the powdered medicine passage hole 633 and the powdered medicine introduction port 636 to communicate with each other.

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

The lock forming piece 650 has a length in the protruding direction longer than that of the lock piece forming portion 276c, and is curved toward the upstream side (left side in FIG. 41(b)) of the fixing plate portion 276a. . As a result, the upper end portion of the lock forming piece 650 extends obliquely upward (in the projecting direction of the entire lock forming piece 650), then upstream, and then obliquely downward. is extended slightly.

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

Here, when the lock mechanism portion 272 is brought into the locked state, as described above, the latching piece forming portion 292 is brought close to cover the lock forming piece portion 650 from above so as to form a lock inside the member housing space 313 . The upper part of the piece 650 is stored. After that, the locking protrusion 315 is inserted into the locking piece insertion hole 283 to engage them.
At this time, in the structure of the locking piece forming portion 276c described above, the user may assume that the locking projection 315 has been inserted even though the locking projection 315 has not been inserted into the locking piece insertion hole 283. There was a possibility that the packaging operation would be performed in a state where the is not engaged.

Therefore, in the present embodiment, the lock forming piece 650 has the above-described 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 positioned in the member storage space 313. It has a structure that does not maintain (is difficult to maintain) the state in which it is inserted.
That is, when the locking piece forming portion 292 is covered with the lock forming piece portion 650 and the locking projection 315 is not inserted into the locking piece insertion hole 283 but is positioned above the locking piece insertion hole 283, the locking is performed. The projection 315 will come into contact with the curved surface formed on the upper side of the locking piece 650 . After sliding along the curved surface, the hooking projection 315 is placed on a portion of the curved surface closer to the upstream side, as shown in FIG. 41(b). Therefore, when the user looks from above, it is possible to immediately determine that the locking projection 315 and the locking piece insertion hole 283 are not engaged.

By the way, the medicine shelf-equipped packaging device 351 described above has a structure in which a controller (not shown) such as a substrate is built in both or one of the tablet cassette shelf 350 and the drug packaging device 1 .
Then, an external device (mobile phone, PC (personal computer), tablet PC, other dispensing equipment) and a built-in control device are brought into a state in which data (signals) can be transmitted and received through a communication network, It is possible to build a drug supply business support system.
Note that the above-described control device and the above-described devices such as mobile phones, PCs, tablet PCs, etc. have computing means composed of an arithmetic processing unit such as a CPU, and information storage means composed of a storage medium such as a memory and a hard disk. It has a structure with Further, the structure is provided with a signal transmitting/receiving means configured by an interface circuit or the like for transmitting/receiving data (signal) to/from the outside.

For this reason, for example, when prescription-related data is input to an external PC, prescription-related data (hereinafter simply referred to as prescription data) to be used in the medicine cabinet-equipped packaging device 351 is created, and based on this prescription data, You may operate the packaging apparatus 351 with a medicine shelf.

Furthermore, the prescription data may be created by a user of the packaging device 351 with a medicine cabinet, such as a pharmacist, directly inputting data relating to the prescription into the packaging device 351 with a medicine cabinet.

In addition, this prescription data may include information on the patient to whom the drug is provided, information specifying the prescribed drug, information on the date the drug was provided, information on the number of days taken, and information on the timing of administration. . Alternatively, the information may be formed by associating these pieces of information.
Furthermore, the above-described patient information may include data such as patient ID, patient name expressed in kanji or kana characters, date of birth, address, telephone number, and the like.
The information specifying the prescribed drug includes drug ID, drug name, information specifying the tablet container 360 (cassette number, container ID, etc.), administration start date (dispensing date), administration days , dosage (usage), number of packets provided, and other data may be included. In addition, data for specifying the drug provider (organization name, facility name, department name, etc., for example, medical institution name, department name, etc.) may be included.
Furthermore, based on the prescription, it may contain information specifying whether or not the medicine shelf-equipped packaging device 351 has already carried out the packaging operation.
The information on the dosing time is information specifying whether the provided drug should be taken in the morning, noon, or night.

Note that the storage means of the packaging device 351 with medicine cabinet or an external device may store information about the inventory amount (capacity of tablets) of each tablet container 360 that can be held in the container mounting portion 361 . That is, the inventory amount may be calculated and stored based on the prescription data each time the packaging operation is performed.

Here, as described above, when the tablets are supplied from the tablet cassette shelf 350 to the medicine packaging device 1, the medicine shelf-equipped packaging device 351 is configured such that from the inside of the tablet container 360 held by the container mounting portion 361, the downward side thereof is placed. (see FIG. 29). Then, the tablet is conveyed inside the tablet supply device 362 and supplied to the medicine packaging device 1 from the tablet extrusion path 484 of the tablet supply device 362 (see FIG. 29).

At this time, in the tablet feeder 362, as described above, the tablet dropped from above is introduced into the tablet receiving portion 365 positioned below (see FIG. 30). Then, the tablets are supplied to the tablet push-out section 368 through different transport paths depending on the introduction position of the tablet. That is, when a tablet is introduced around the center in the left-right direction, the tablet is supplied to the tablet push-out portion 368 via the drop path forming portion 367 . On the other hand, when the tablet is introduced into either of the left and right ends, the tablet passes through one of the left and right horizontal conveying units 366 and the drop path forming unit 367 to the tablet pushing unit 368. supplied.

More specifically, in the upper portion of the container mounting portion 361, as shown in FIG. 29, the tablet containers 360 are arranged in a matrix and stored. More specifically, 11 rows of tablet containers 360 are formed by forming six tablet containers 360 aligned in the vertical direction, and the rows of these tablet containers 360 are arranged in the horizontal direction.

42, eleven tablet drop paths 660 (tablet supply paths) corresponding to the rows of the tablet containers 360 are formed on the back side of the container mounting portion 361. As shown in FIG. That is, the same number of tablet dropping paths 660 as the number of rows of tablet containers 360 are formed.
Each tablet drop path 660 forms a vertically extending space surrounded by a peripheral wall and corresponds to a different row of tablet containers 360 . It also forms a path along which tablets supplied from one or more tablet containers 360 belonging to the row of corresponding tablet containers 360 drop.

Specifically, for example, the rightmost row of tablet containers 360 (see FIG. 29) corresponds to the rightmost (leftmost in FIG. 42) tablet drop path 660k. The tablets supplied from the tablet container 360 belonging to the rightmost row are supplied to the tablet supply device 362 through the rightmost tablet dropping path 660k regardless of which tablet container 360 is supplied. . Similarly, the column of tablet containers 360 positioned second from the right corresponds to the tablet drop path 660j positioned second from the right, and so on, and so on, in a one-to-one correspondence.

Note that the tablet dropping paths 660b and 660j positioned at both ends in the left and right direction are provided with drop regulating portions 662 for regulating the movement direction of tablets falling inside.
The drop control portion 662 is a plate-like member that is attached in an inclined posture, and the upper surface thereof is an inclined surface that slopes downward from the end portion side toward the center side in the left-right direction. The upper end portion of the upper surface of the fall restricting portion 662 is arranged at a position closer to the end portion in the left-right direction. That is, the drop restricting portion 662 is a space located below or inside the tablet dropping paths 660b, 660j (a space located below in FIG. 42), and extends diagonally across the space where the tablet drops. there is
Therefore, when the tablets that have fallen down the tablet dropping paths 660b and 660j fall onto the drop regulation portion 662, their movement direction is changed and they drop closer to the center in the horizontal direction.

Tablets introduced into the tablet supply device 362 via the centrally located tablet drop path 660f are supplied to the tablet push-out section 368 (not shown in FIG. 42) via the drop path forming section 367.
On the other hand, a tablet introduced into the tablet supply device 362 through one of a plurality of tablet dropping paths 660 (tablet dropping paths 660a to 660e) located on one side in the left-right direction of the central tablet dropping path 660f. is introduced into one of the horizontal conveying sections 366 .
Furthermore, tablets introduced into the tablet feeding device 362 through any of the plurality of tablet dropping paths 660 (tablet dropping paths 660g to 660k) located on the other side in the left-right direction from the central tablet dropping path 660f , is introduced into the other horizontal transport section 366 .

Here, as described above, the inside of the horizontal conveying section 366 has a structure in which a tablet that has fallen to any position in the medicine receiving groove section 410 is pressed by the tablet pushing piece section 438 (see FIG. 33). That is, by moving the tablet push-out piece 438 from the left-right end to the center, the tablets falling at different positions in the left-right direction are pushed toward the drop path forming portion 367 .

When performing this pressing operation, the tablet push-out piece portion 438 is positioned closer to the tablet drop path 660 (tablet drop path 660a or tablet drop path 660k) located at the end in the left-right direction than the drop position of the tablet supplied. , and waits at a position away from the edge in the left-right direction.
Specifically, in the horizontal conveying section 366 located on one end side in the left-right direction (right side in FIG. 42), the tablet supplied from the tablet drop path 660a located on the one end side in the left-right direction is dropped. Also, the position on the one end side in the left-right direction is set as the reference standby position.
After the tablet is dropped while the tablet push-out piece 438 is waiting at the reference standby position, the tablet push-out piece 438 is moved to the center in the left-right direction to press the tablet.
Note that the horizontal conveying portion 366 located on the other side in the left-right direction (the left side in FIG. 42) has the same basic structure as that of the horizontal conveying portion 366 located on the one side. Description is omitted.

Here, in the packaging device with medicine shelf 351 (tablet cassette shelf 350) of the present embodiment, by operating based on the prescription data as described above, the tablet push-out piece portion 438 waits at a position different from the reference standby position. After that, it is possible to press the tablet. This operation will be described in detail below.

When the operation of supplying tablets to the medicine packaging apparatus 1 is started, the medicine shelf-equipped packaging apparatus 351 of the present embodiment performs a container specifying operation of specifying the tablet container 360 containing the tablets to be supplied.
That is, based on the prescription data and the data stored in the RFID tag attached to each tablet container 360, the tablet containers 360 containing tablets supplied from a plurality of tablet containers 360 arranged in parallel in a matrix are selected. Identify. Further, the position of the container mounting portion 361 where the tablet container 360 containing the supplied tablets is specified.

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

Furthermore, based on the result of the container identifying operation, the tablet dropping path 660 used when supplying tablets to the tablet feeding device 362 is identified, and whether or not the horizontal conveying section 366 is to be used is identified. That is, it is specified whether or not the horizontal conveying section 366 is to be used, and if so, which horizontal conveying section 366 is to be used. In other words, it is specified whether both of the two horizontal conveying units 366 are to be used, or which horizontal conveying unit 366 is to be used if only one of them is to be used.

Furthermore, when the horizontal conveying unit 366 is used, the tablet dropping path 660 located at the end in the left-right direction is also identified among the tablet dropping paths 660 that supply tablets to the horizontal conveying unit 366 to be used. be. In other words, the tablet drop path 660 located on the most upstream side in the moving direction of the tablet pushing piece portion 438 is specified.
Specifically, 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 moving direction of the pushing operation of the tablet pushing piece section 438, and the left end side is the downstream side. In other words, the tablet dropping path 660a located on the most upstream side becomes the tablet dropping path 660 located on the most end side in the left-right direction.
On the other hand, in the other horizontal conveying 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 pushing piece section 438, and the right end side is the downstream side. In other words, the tablet drop path 660k positioned furthest upstream becomes the tablet drop path 660 positioned furthest to the end in the left-right direction. That is, on both sides of the drop path forming portion 367, the direction of movement of the tablet push-out piece 438 in the pushing operation is opposite, and the side of the drop path forming portion 367 where the tablet is pushed out is the downstream side in the moving direction.

Then, a standby position determination operation for determining the standby position of the tablet push-out piece portion 438 is performed based on the above identification result.
For example, as shown in FIG. 42(a), if the tablet is to be supplied to the horizontal transport section 366 from the tablet dropping path 660a located at the extreme end in the left-right direction, the reference standby position is the standby position of the tablet pushing piece section 438. position.

On the other hand, as shown in FIG. 42(b), the tablets are not supplied from the tablet dropping path 660a located at the extreme end side in the left-right direction, and the tablet dropping paths 660c and 660e further away from the center side in the left-right direction. , the standby position of the tablet pushing piece portion 438 is changed.
That is, among the tablet dropping paths 660 through which the tablets to be supplied to the horizontal conveying section 366 pass, the tablet dropping path 660c located on the end side in the left-right direction (the upstream side in the moving direction of the tablet push-out piece portion 438) is specified. be. The standby position (changed standby position) of the tablet push-out piece 438 is a position that is closer to the end in the horizontal direction than the specified tablet drop path 660c and is closer to the central side in the horizontal direction than the reference standby position.
That is, it is determined whether or not the tablet is supplied from the tablet dropping path 660a located at the end in the left-right direction, and based on the determination result, the standby position of the tablet pushing piece portion 438 is determined. . Then, after the tablet pushing piece portion 438 is made to wait at the determined waiting 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 horizontal direction than each of the tablet dropping paths 660b to 660e. In this case, among the tablet dropping paths 660 through which the tablets to be supplied to the horizontal conveying unit 366 pass, when the most upstream channel is positioned on the end side in the horizontal direction, The change standby position is a position slightly on the end side in the direction. In other words, when the tablet drop path 660e positioned most centrally in the left-right direction is the most upstream channel, the changed standby position is set slightly on the edge side in the left-right direction of the tablet drop path 660e. Similarly, when the tablet drop path 660d located second from the center side in the left-right direction is the most upstream flow path, the left-right direction side of the tablet drop path 660d is slightly on the side of the change standby position, and the third and subsequent positions are positioned. The same is true for

On the other hand, only one change standby position may be set.
For example, the change standby position may be a position on the end side in the left-right direction of the specific tablet drop path 660c. In this case, when the most upstream channel is the specific tablet drop path 660c, and the tablet drop path 660 (tablet drop paths 660d, 660e) located on the center side in the left-right direction from the specific tablet drop path 660c , the tablet pushing piece portion 438 waits at the change waiting position. On the other hand, when the most upstream channel is the tablet drop path 660 (tablet drop paths 660a and 660b) located on the end side in the left-right direction from the tablet drop path 660c, the tablet pushing piece portion 438 is at the reference standby position. wait at

In this way, only one change standby position may be set, or a plurality of positions may be set. That is, when the tablet falls between the reference standby position and the change standby position located on the end side in the left-right direction from the reference standby position, the rear tablet pushing piece portion 438 may be made to wait at the reference standby position. . In addition, when the tablet drops downstream from a specific change standby position, the tablet pushing piece portion 438 is pushed at the change standby position located furthest downstream among the change standby positions located upstream of the tablet drop position. You should wait.
In addition, in the above example, an example in which the drop control portions 662 are provided in the tablet drop paths 660b and 660j has been described, but the drop control portions 662 may be provided in other tablet drop paths 660 as appropriate. That is, any tablet dropping path 660 may be provided with the drop regulation portion 662 , or none of the tablet dropping paths 660 may be provided with no drop regulation portion 662 . The change standby position may be a position on the upstream side of the vicinity of the lowermost end of the drop restricting portion 662 . Note that the tablet receiving portion 365 may be partitioned based on the position where the drop restricting portion 662 is provided. In other words, the positions where the connecting member placement portion 371 and the partition member 372 are formed may be shifted in the left-right direction from the position above the drop restricting portion 662 in the vertical direction.

Furthermore, the above-described tablet conveying operation that accompanies the waiting position determining operation may be performed based on the information regarding the dosing time in the prescription data.
For example, among the medicines prescribed for a predetermined patient, the medicine to be taken in the morning, the medicine to be taken in the afternoon, and the medicine to be taken in the evening can be sequentially packaged by the packaging device 351 with the medicine shelf. When implemented, a tablet conveying operation accompanied by a standby position determination operation may be implemented in each packaging operation. That is, the tablet conveying operation accompanied by the standby position determination operation may be performed each time the tablet packaging operation is performed.

Conversely, when a packing action is performed for each prescription prescribed to a plurality of patients, such as packing a drug prescribed for one patient and packing a drug prescribed for another patient. , the standby position determination operation may be performed only once in the operation for one prescription.
That is, when a plurality of packing operations are performed, such as separately packaging a medicine to be taken in the morning, noon, and night in the operation for one prescription, the packaging is performed by a plurality of packing operations. The operation of identifying the most upstream flow path is performed for all tablets. Then, the standby position of the tablet push-out piece portion 438 is determined based on the specified most upstream flow path. In addition, when the packaging operations are sequentially performed, the standby position of the tablet push-out piece 438 before the push-out operation can be set to the same determined position in each operation. That is, the standby position determining operation may be performed for a plurality of packaging operations, and the tablet conveying operation may be performed a plurality of times based on the results of the standby position determining operation performed in advance.

By the way, as described above, the tablet push-out section 368 has a structure in which the tablet conveying device 474 is linearly moved to convey the tablet while the tablet is placed inside the housing hole 520 (see FIG. 36). ).
Here, when the tablet conveying device 474 is moved forward (to the right in FIG. 36) to convey the tablet to the medicine packaging device 1 side, it is preferable to move the tablet conveying device 474 at high speed and then at low speed. . That is, in order to reliably stop the tablet conveying device 474 at a specified position, the speed of the tablet conveying device 474 after a predetermined time has passed since the start of movement (the speed of the tablet conveying device 474 that has moved a predetermined distance) is set lower than that at the start of movement. preferably.

Furthermore, it is preferable to temporarily send a stop signal to a driving device (such as a motor) that drives the tablet conveying device 474 .
Specifically, when moving the tablet conveying device 474 to the front side, an operation of temporarily stopping the driving device during movement is performed. At this time, since the tablet conveying device 474 moves as it is due to inertia, the driving device is driven again with 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. As a result, the tablet conveying device 474 can be brought to a deceleration state more quickly than the operation of simply reducing the output of the driving device while the tablet conveying device 474 is moving.

By the way, as described above, the medicine cabinet-equipped packaging device 351 can supply a maximum of 66 types of tablets from the tablet containers 360 to the medicine packaging device 1 . The container attachment part 361 has a plurality of individual installation parts, and each individual installation part is a part for holding (storing) each tablet container 360 . That is, the number of individual installation portions 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 medicine cabinet-equipped packaging apparatus 351 is operated, the tablets provided to the patient may vary greatly every day or every specific period. Therefore, it is preferable to change the tablet container 360 held by the container mounting portion 361 appropriately from the viewpoint of efficiently operating the packaging device 351 with a medicine shelf.
Therefore, in the packaging apparatus 351 with a medicine shelf of the present embodiment, the recommended cassette screen 670 (recommended container presentation screen) shown in FIG. It is possible to make it easier.

As shown in FIG. 43, the recommended cassette screen 670 includes an installation status display portion 675, a scheduled tablet display portion 676, a target data change portion 677, a data adjustment button 678, a list display change button 679, and an end button. 680 is displayed on the screen. That is, the screen displays these parts and buttons simultaneously in a visible state.

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

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

Then, in the diagram displayed on the installation status display section 675, when each individual installation section satisfies a specific condition, the portion corresponding to the individual installation section that satisfies this condition is highlighted. Specifically, when the individual installation unit is in any of the replaceable state, the non-mounted state, and the small quantity state, each is highlighted in a different color.

Each condition will be explained. To be “exchangeable state” means that the tablet container 360 containing the tablets not listed in the scheduled tablet display portion 676 is attached to the target individual installation portion. state.
Further, the “unattached state” is a state in which the tablet container 360 is not attached to the target individual installation portion.
Furthermore, the “small amount state” means that although the tablet container 360 containing the tablets listed in the scheduled tablet display portion 676 is attached to the target individual installation portion, there will be a shortage of tablets in the future. It is expected that
Specifically, the inventory amount of tablets stored in the attached tablet container 360 is below the amount used in the packaging operation expected 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 portion and which tablet should be filled in advance by simply comparing the installation status display portion 675 and the scheduled tablet display portion 676. can be easily grasped.

Here, since the medicine shelf-equipped packaging apparatus 351 of the present embodiment performs the above-described display operation with the installation status display section 675 and the scheduled tablet display section 676, there is a possibility that the packing operation will be performed within the specified period. Perform a used tablet prediction operation that identifies high tablets.
This tablet to be used prediction operation will be described in detail below with descriptions of various buttons.

The tablet to be used prediction operation is roughly divided into data that has been packaged in the past (hereinafter also referred to as packaged data) and data that has not yet been packaged at the time the recommended cassette screen 670 is displayed (hereinafter undivided data). (also called hull data). That is, it is possible to target either the packaged data or the unpackaged data among the prescription data.
By operating each button of the target data changing section 677, it is possible to change the target data in the tablet to be used prediction operation.

Specifically, by pressing the DO data button 677a, which is one of the paired two buttons, the used 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 portion 675 and the scheduled tablet display portion 676 .

In the tablet-to-be-used prediction operation, in the case of packaged data, an assumed date specifying operation for specifying the date on which a tablet is expected to be prescribed to a patient (hereinafter also referred to as an assumed date) is performed in advance for all patients. After that, an operation of identifying patients whose assumed dates are included in the specified period is performed. Then, based on the data associated with the identified patient, tablets that are highly likely to be subject to the packing operation within the designated period are identified. When the unpacked data is targeted, the target tablet for the packing operation included in the unpackaged data is identified without performing the assumed date specifying operation.

In the assumed date specifying operation, the date on which the prescribed tablet will be gone from the patient's hand is calculated for each patient based on information on the administration start date of the tablet prescribed for each patient and the number of administration days. That is, by adding the number of administration days to the administration start date, the date when the tablet will no longer be available to the patient is calculated. Then, the same day as the date when the prescribed tablet disappears from the patient's hand, or a date obtained by subtracting a predetermined period from this date (for example, the day before the day when the prescribed tablet disappears) is set as an assumed date.

Then, patients whose assumed dates are included in the specified period are extracted, and data on tablets provided to each of the extracted patients on the assumed dates is acquired. More specifically, it acquires or calculates the type of tablet, the dose, and the number of packages.
It should be noted that, in the case of prepackaged data, it is assumed that the tablets prescribed in the past are provided to each patient again on the assumed date.
Based on this, tablets that are highly likely to be packaged during the specified period are identified.
