When the drug delivery of the storage cassette 1 is completed, the first drug storage cassette 1 is placed on the cassette shelf prior to the transportation for delivering the fourth drug storage cassette 1 to the fourth delivery unit 3. It is conceivable to execute the process of returning to 1011. However, in such a process, although the drug withdrawal from the second drug containing cassette 1 is completed and the drug withdrawal from the fourth drug containing cassette 1 can be started, the fourth drug can be started. It may happen that the drug dispensing cannot be started in the storage cassette 1. This increases the time required for the dispensing process of a plurality of drug sheets.

In the operation example shown in FIG. 3, the transfer of the drug containing cassette 1 to the four delivery sections 3 is sequentially repeated, and then the drug containing cassette 1 for which the PTP sheet 100 has been paid out is delivered from the delivery section 3. The transport to return to the cassette shelf is repeated in sequence. According to this, when the drug withdrawal in the second drug containing cassette 1 is completed and the drug payout of the fourth drug containing cassette 1 can be started, the drug payout of the fourth drug containing cassette 1 is immediately performed. You will be able to start. Therefore, the time required for the dispensing process of a plurality of drug sheets can be shortened.

Next, the drug storage cassette 1, the cassette loading / unloading section 21, the moving mechanism 22, the delivery section 3, the payout operation section 110, the delivery section moving section 4, and the tray moving section 5 , Each structural example will be explained.

[Drug storage cassette]
As shown in FIGS. 5 and 6, the dispensing section 120 of the drug containing cassette 1 is provided with first limiting sections 121 at two upper and lower positions.

The first limiting portion 121 includes a contact member 121a that contacts the upper edge or the lower edge of the leading PTP sheet 100, and the contact member 121a so that the contact member 121a can overcome the upper edge or the lower edge of the PTP sheet 100. A support portion 121b that movably supports the 121a and a spring 121c that urges the contact member 121a in a direction in which the PTP sheet 100 is stopped are provided.

The support portion 121b has a horizontal axis, and the contact member 121a is rotatably supported around the horizontal axis. Then, the spring 121c is wound around the support portion 121b and both ends are fixed. Then, the central portion of the spring 121c is engaged with the contact member 121a.

The upper first limiting portion 121 is provided on the vertically movable upper frame portion 123 that constitutes the upper frame portion of the payout portion 120. Dials 123a are rotatably engaged with both ends of the upper frame portion 123. The dial 123a is screwed into the screw portion 123b, and when the dial 123a is rotated, the dial 123a moves up and down. The screw portion 123b is provided on the cassette main body portion. When the dial 123a moves in the vertical direction, the upper frame portion 123 moves in the vertical direction. That is, when the dial 123a is turned, the upper frame portion 123 moves in the vertical direction, and the height of the payout portion 120 (the height of the upper contact member 121a) can be adjusted. Therefore, a plurality of types of PTP sheets 100 having different heights can be stored by using the drug storage cassette 1 having a common structure.

Further, the drug accommodating cassette 1 is provided with an accommodating size adjusting mechanism in which the accommodating size is changed by moving the size adjusting member and the adjusting position of the size adjusting member corresponding to the accommodating size is indicated. May be good. For example, a number of accommodation sizes 1 to 3 is printed or engraved in the vertical direction on the side supporting the dial 123a, and an arrow is attached to the upper frame portion 123 as the size adjusting member that moves by rotating the dial 123a. The mark is printed or engraved so as to indicate the number of the accommodation size. The arrow mark will indicate the currently set accommodation size number. When the operator turns the dial 123a and the arrow mark points to the accommodation size "3", the upper frame portion 123 is set to the third accommodation size.

The size information for each drug is stored in the master table. For example, if the drug A is stored in the drug storage cassette 1 of No. 25 and the size information about the height of the PTP sheet 100 of the drug A is "2", the control unit 1005 is displayed on the display 1002. It is displayed that the size information about the height of the PTP sheet 100 of the drug A is "2". When the operator displays "2" as the size information about the height of the PTP sheet 100 of the drug A on the display 1002, the arrow mark on the drug storage cassette 1 of the 25th drug A is numbered "2". Turn the dial 123a as it points. As a result, even if the worker is not an expert, the upper frame portion 123 can be set at a position suitable for the height of the PTP sheet 100 of the drug A.

Further, the upper frame portion 123 is provided with two seat holding portions 124 on both sides of the first limiting portion 121. As shown in FIG. 7, the seat holding portion 124 is integrally formed with the seat contact portion 124a and the spring portion 124b. The spring portion 124b is supported by the upper frame portion 123, and the seat contact portion 124a presses the PTP sheet 100 downward with an appropriate force.

Apart from the first limiting portion 121, the second limiting portion 122 is provided at two positions on the left and right so as to come into contact with the left and right edges of the leading PTP sheet 100. The second limiting portion 122 is composed of an elastic piece portion that can be deformed in the left-right direction of the payout portion 120. The left and right edges of the leading PTP sheet 100 come into contact with the second limiting portion 122. At the tip of the second limiting portion 122, a locking portion 122a formed in a V-groove shape capable of sandwiching the left and right edges of the PTP sheet 100 in the accommodating portion 11 is formed, and the leading PTP sheet is formed. The movement of 100 is restricted by locking its left and right edges to the locking portion 122a. The rear end portion of the second limiting portion 122 is engaged with the guide side plates 125 arranged on the left and right sides of the accommodating portion 11. A notch is formed at a position of the guide side plate 125 where the second limiting portion 122 is provided, and the locking portion 122a is located in the notch. The PTP sheet 100 is guided by the guide side plate 125, but at this time, the left and right edges of the PTP sheet 100 do not penetrate too deeply into the V-groove shape.

As shown in FIG. 8, the PTP sheet 100 is accommodated in the accommodating portion 11 of the drug accommodating cassette 1 so that the long side is horizontally oriented and the short side is vertically oriented. Therefore, the first limiting portion 121 is in contact with the edge of the long side of the PTP sheet 100, and the second limiting portion 122 is in contact with the edge of the short side of the PTP sheet 100.

As shown in FIG. 9, the left and right guide side plates 125 are each provided with an urging portion 126. The urging portion 126 urges the guide side plate 125 so that the tip side (the side closer to the payout portion 120) of the left and right guide side plates 125 is closer to each other. The rear end side of the guide side plate 125 is engaged with the left and right rising top plates of the cassette main body portion, and the urging portion 126 is located between the rising top plate and the guide side plate 125. Further, the angle formed by the urging portion 126 with the guide side plate 125 is regulated by the position of the angle regulating member 126b fitted into the serrated concave-convex portion 126a in the moving direction of the PTP sheet 100. The angle regulating member 126b can move in the moving direction of the PTP sheet 100 with respect to the serrated uneven portion 126a. As the angle regulating member 126b is moved farther from the payout portion 120, the maximum angle formed by the urging portion 126 and the guide side plate 125 becomes larger, and the tip portions of the left and right guide side plates 125 come closer to each other. Therefore, even if the size of the PTP sheet 100 is small and its left and right edges do not come into contact with the guide side plates 125 on the rear end side of the left and right guide side plates 125, the tips of the left and right guide side plates 125 It is guided in contact with the guide side plate 125, and the leading PTP sheet 100 is guided to the center of the payout portion 120. That is, a plurality of types of PTP sheets 100 having different width sizes can be stored by using the drug storage cassette 1 having a common structure.

Further, for example, the accommodation size numbers 1 to 3 are printed or engraved in the vicinity of the sawtooth-shaped uneven portion 126a, and are currently set by the location where the angle regulating member 126b as the size adjusting member is located. The number of the accommodation size may be shown to the operator. When the operator aligns the angle regulating member 126b with the position of "3", the guide side plate 125 is set to the third accommodation size. The size information for each drug is stored in the master table. For example, if the drug A is stored in the drug storage cassette 1 of No. 25 and the size information about the width of the PTP sheet 100 of the drug A is "2", the control unit 1005 displays the drug A on the display 1002. It is displayed that the size information about the height of the PTP sheet 100 of A is "2". When the display 1002 shows that the size information about the width of the PTP sheet 100 of the drug A is "2", the operator sets the angle regulating member 126b in the drug storage cassette 1 of the 25th drug A to "2". 2 ”. As a result, even if the operator is not an expert, the guide side plate 125 is set at a position suitable for the width of the PTP sheet 100 of the drug A.

The moving operation unit 130 includes, for example, a pressing member 131 that comes into contact with the PTP sheet 100 and a constant load spring (for example, a trade name Conston spring) 132. The pressing force of the constant load spring 132 is set so that the PTP sheet 100 does not get over the first and second limiting portions 121 and 122 only by this pressing force. The constant load spring 132 is provided with a lock portion 132a, and the PTP sheet 100 can be set in a state where the moving operation portion 130 is moved to a rear position and locked. Then, when the lock is released after setting the PTP sheet 100, the pressing operation against the PTP sheet 100 is started. Further, the constant load spring 132 has a winding spring, and the tip end portion of the winding spring is fixed in the vicinity of the payout portion 120. The lock portion 132a is provided with a gear portion 132b. The gear portion 132b meshes with the tooth-shaped portion 11a formed on the bottom surface of the housing portion 11, and the moving operation portion 130 is locked by restricting the rotation of the gear portion 132b. It becomes. Further, if the gear portion 132b is provided with, for example, a damper (for example, an oil damper) 132c, the operating speed of the moving operating portion 130 can be adjusted. In this case, the damper 132c serves as an adjusting means for adjusting the speed at which the moving operation unit 130 moves the PTP sheet 100.

The sheet storage unit 141 is located above the payout unit 120 in the open state shown in FIG. The payout unit 120 faces the suction main body 61 (see FIG. 30), which will be described later, when the PTP sheet 100 is paid out. Then, the back wall portion 1411 of the sheet storage portion 141 faces the suction main body portion 61 when it is moved upward from the time of payout. A plurality of height adjusting holes 1411a are formed on the upper side of the back wall portion 1411 at intervals in the height direction. A height direction limiting plate 142 as a size adjusting member is detachably attached to the back wall portion 1411 by the height adjusting hole 1411a.
Since the mounting height of the height direction limiting plate 142 can be changed according to the height of the PTP sheet 100 housed in the sheet storage unit 141, when the lid 140 is rotated, the above It is possible to prevent the PTP sheet 100 for fractional chemicals from falling from the sheet storage unit 141.

For example, numbers of accommodation sizes 1 to 3 corresponding to the formed heights may be printed or engraved in the vicinity of the plurality of height adjusting holes 1411a. If the operator adjusts the mounting location of the height direction limiting plate 142 to "2", the height direction limiting plate 142 will be set to the second height. In the master table, the number of the storage size of the sheet storage unit 141 is stored for each drug. For example, if the drug A is stored in the drug storage cassette 1 of No. 25 and the storage size number of the sheet storage unit 141 regarding the PTP sheet 100 of the drug A is "2", the control unit 1005 is described as described above. The display 1002 shows that the number of the accommodation size of the sheet storage unit 141 in the drug A is "2". When the display 1002 shows that the storage size number of the sheet storage unit 141 of the drug A is "2", the operator can see the sheet storage unit 141 of the drug storage cassette 1 of the 25th. Align the mounting location of the height direction limiting plate 142 with "2". Thereby, even if the operator is not an expert, the height direction limiting plate 142 can be set at a position suitable for the height of the PTP sheet 100 of the drug A.

A rising portion 242a is formed on the left and right edges of the bracket 242, and each rising portion 242a is fixed to the slider 251b of the rail unit 25. Further, a moving nut 243 is fixed to the central portion of the bracket 242. The moving nut 243 is screwed into the feed screw 255 of the rail unit 25. Therefore, the rotation of the feed screw 255 causes the cassette grip portion 24 to move in the front-rear direction of the drug dispensing device 101.

The base portion 241 is provided with a feed screw 241a in the left-right direction of the drug dispensing device 101. Both ends of the feed screw 241a are rotatably supported by two left and right brackets 241b. Further, screw portions whose screw cutting directions are opposite to each other are formed at both ends of the feed screw 241a, and a moving nut 244a is screwed into each screw portion. Then, two slide shafts 241c are supported by the base portion 241 in parallel with the feed screw 241a. Both ends of the slide shaft 241c are fixed by the two brackets 241b.

A chuck plate 244 is provided between the left and right brackets 241b and the base portion 241. The moving nut 244a is provided on the upper center side of each chuck plate 244. Further, a linear bush 244b is provided on the upper portion of each chuck plate 244 so as to sandwich the moving nut 244a. The slide shaft 241c is inserted through each linear bush 244b. A gear 245a in the drive unit 245 is fixed to the feed screw 241a. A gear 245b is meshed with the gear 245a. The gear 245b is rotated by a motor 245c. The rotation of the motor 245c causes the feed screw 241a to rotate, and this rotation causes the chuck plates 244 to approach each other and separate from each other. As a result, the side plate portion of the drug containing cassette 1 can be gripped from the side.

The chuck plate 244 is provided with a receiving portion 244c made of a flexible material, and the receiving portion 244c is adapted to hit the side plate portion of the drug containing cassette 1. Further, a positioning member 244d is provided at the front end of the chuck plate 244. The positioning member 244d is rotatably provided around the vertical axis.

Positioning recesses 1a are formed on the outside of the left and right side plates near the front end of the drug storage cassette 1 (see FIG. 11A). When the drug storage cassette 1 is pulled out from the cassette shelf 1011 and the side plate portion is gripped by the chuck plate 244, the positioning member 244d engages with the positioning recess 1a. When such engagement is performed, the chuck plate 244 grips the appropriate position of the drug containing cassette 1. When the side plate is gripped by the chuck plate 244, even if there is some misalignment between the positioning member 244d and the positioning recess 1a, the side plate is gripped by the chuck plate 244. By force, the positioning member 244d can be engaged with the positioning recess 1a. If the receiving portion 244c made of the flexible material is provided, the engagement is likely to occur.

Even when the cassette grip portion 24 comes closest to the cassette shelf 1011 due to the rotation of the feed screw 255, the cassette grip portion 24 is located in front of the cassette shelf 1011. Then, when the claw moving portion 231 comes closest to the rising wall 11b, the claw moving portion 231 is located on the notch portion 11c. Then, when the bifurcated claw 231a is rotated by the rotation driving unit 231b, the rising wall 11b is sandwiched between the bifurcated portions. In this state, when the claw operating portion 231 moves to the retracted position, the chuck plate 244 of the cassette gripping portion 24 is in a state where the drug accommodating cassette 1 can be gripped. When the drug storage cassette 1 is gripped by the chuck plate 244, the bifurcated claw 231a of the front-rear moving portion 23 returns to the original state (non-engaged state) as described above. As a result, the cassette gripping portion 24 can additionally move in the forward direction of the drug dispensing device 101 while gripping the drug containing cassette 1, and the additional moving causes the drug containing cassette 1 to be completely pulled out from the cassette shelf 1011. .. That is, in the gripped state, the drug storage cassette size is moved by a distance obtained by subtracting the first distance (additional movement), and the entire drug storage cassette 1 is pulled out from the cassette shelf.

When returning the drug storage cassette 1 to the cassette shelf 1011, after performing the reverse operation of the additional movement, the bifurcated claw 231a is engaged with the rising wall 11b, and the bifurcated claw 231a is provided by the front-rear moving portion 23. The drug containing cassette 1 is completely returned to the cassette shelf 1011 by moving.

Further, the base portion 41 is formed with a third guide 41c in each delivery portion moving portion 4, and the third pin 31d is guided by each third guide 41c. The two third guides 41c have a left-right straight guide portion extending in the left-right direction of the drug dispensing device 101. Then, the two left and right straight guide portions are connected to the common guide portion via the intermediate guide portion. The common guide unit is located between the two delivery unit moving units 4.

When the swivel arm 42a is swiveled by the motor 42, the swivel base plate 36 in the delivery portion 3 moves in an arc along the first arc guide 41a and the second arc guide 41b. On the other hand, the straight-ahead base plate 31 in the delivery portion 3 tries to move in an arc by receiving the moving force of the swivel base plate 36, but since the third pin 31d is guided by the third guide 41c, it is left. Or move straight to the right. Then, the straight-ahead base plate 31 is moved to the rear side of the drug dispensing device 101 by the common guide section, and the drug accommodating cassette 1 chucked by the delivery section 3 is made to face the dispensing operation section 110. The relative position change between the straight base plate 31 and the swivel base plate 36 is absorbed by the rail and the slider.

After the drug containing cassette 1 chucked by the delivery section 3 faces the payout operation section 110, the lid 140 of the drug containing cassette 1 is opened by the lid opening / closing section 160 of the payout operation section 110.

As shown in FIGS. 23, 24 and 25, the sheet stocker 112 is provided in the payout operation unit 110. The sheet stocker 112 is provided below the lid 140 of the drug storage cassette 1 at a position where the drug storage cassette 1 chucked by the delivery unit 3 faces the payout operation unit 110. .. The hopper portion 112a of the sheet stocker 112 temporarily accommodates the PTP sheet 100 and a fraction of the packaged medicines dispensed from the payout portion 120 of the medicine containing cassette 1.

The bottom of the hopper portion 112a is composed of the first shutter 112b, which is the storage shutter. Further, a drop cylinder portion is formed in the lower portion of the first shutter 112b, and a second shutter 112c, which is the storage shutter, is provided at the bottom of the drop cylinder portion (drug sheet outlet portion 1120).

A link member 112f is connected to the swivel arm 112e, and the link member 112f is connected to the first shutter 112b. When the drive motor 112d rotates, the swivel arm 112e rotates, the link member 112f moves, and the first shutter 112b opens and closes. The first shutter 112b and the second shutter 112c are guided by a slide shaft 112g.

As shown in FIG. 26, a drug sheet such as PTP sheet 100 has flat edges (sheet portions) at both ends, but one edge is wider than the other edge. This wide edge 100a is generally called an ear. In the drug dispensing device having a function of cutting out a fractional packaged drug from the drug sheet, if the orientation of the pocket of the PTP sheet 100 taken out from the drug storage cassette 1 or the orientation of the wide edge 100a is undefined, the fractional packaged drug May not be cut out properly. For the PTP sheet 100 that is not the target for cutting out fractions, it is not necessary to detect the orientation of the pocket and the orientation of the wide edge 100a.

Further, FIG. 26 shows three axes when the PTP sheet 100 is rotated. The three axes include a normal, a minor axis, and a major axis of the sheet surface of the PTP sheet 100. The minor axis and the major axis are orthogonal to each other in the plane of the PTP sheet 100. As an example of the position of the center of rotation around the long axis, there is an axis passing through the center in the short side direction of the PTP sheet 100. Further, as an example of the position of the center of rotation around the short axis, there is an axis passing through the central portion in the longitudinal direction of the PTP sheet 100. As an example of the rotation center around the normal line, there is an intersection of the rotation center around the long axis and the rotation center around the short axis. Here, the PTP sheet 100 is line-symmetrical on the second axis (long axis). Further, if the rotation center around the normal is provided near the intersection of the rotation center around the long axis and the rotation center around the short axis, the space required for rotation around the normal can be reduced. .. In this embodiment, rotation around the normal line is adopted.

FIG. 27 is an explanatory diagram showing a state change of the PTP sheet 100. The state of the PTP sheet 100 includes a first state in which the pocket is face up and the wide edge 100a is in the left position, a second state in which the pocket is face up and the wide edge 100a is in the right position (state shown in FIG. 26), and the pocket is There is a third state in which the wide edge 100a is face down and the wide edge 100a is in the left position, and a fourth state in which the pocket is face down and the wide edge 100a is in the right position. Regardless of the state of the first PTP sheet 100 paid out, the state changes due to rotation around the long axis, the state changes due to rotation around the short axis, and the state due to rotation around the normal. By causing two state changes out of the changes, it is possible to align to any one state. That is, the pocket direction of the PTP sheet 100 and the wide edge 100a can be oriented in the same direction. It should be noted that the configuration may be such that only the direction of the wide edge 100a is directed to one direction.

[Payout operation unit 110]
As shown in FIGS. 28 and 29, the payout operation unit 110 includes the lid opening / closing unit 160. The lid opening / closing portion 160 includes a shaft portion 161 that engages with the engaging portion formed on the lid 140, and the shaft portion 161 is engaged in a state where the shaft portion 161 is engaged with the engaging portion. The lid 140 is opened and closed by moving it along an arc trajectory. Further, the lid opening / closing portion 160 includes a shaft portion 162 that engages with an engaging portion formed in the seat storage portion 141, and the shaft portion 162 is engaged with the engaging portion. By rotating the shaft portion 162, the sheet storage portion 141 is rotated.

Further, the payout operation unit 110 is provided by a suction operation unit 6 for sucking and pulling out the leading PTP sheet 100 in the drug storage cassette 1, and a suction operation unit 6 when a fractional packaging drug is required. A sheet gripping portion 8 that grips and receives the pulled out PTP sheet 100, and a PTP sheet 100 pulled out by the suction operation unit 6 when a fractional packaging agent is required, with the normal line of the sheet surface as an axis. A normal rotating portion 13 for rotating is provided. The normal of the sheet surface is the normal at the center position of the sheet surface of the PTP sheet 100. Here, the normal at the center position of the sheet surface is parallel to the perpendicular line (orthogonal line) of the sheet surface when the PTP sheet 100 is assumed to be a flat surface instead of a curved surface. Further, in this embodiment, the direction of the normal line of the sheet surface is equal to the front-rear direction, the direction in which the PTP sheets 100 are lined up in the drug storage cassette 1, and the moving direction of the drug storage cassette 1. Further, at the time of paying out the PTP sheet 100, the normal rotating portion 13 is positioned at the center position of the payout portion 120 of the drug containing cassette 1 (the center position of the PTP sheet 100).

The seat gripping portion 8 includes a gripping main body 81 rotatably provided around a horizontal axis, a rotating portion 82 for rotating the gripping main body 81, and a left-right moving device 83 for moving the rotating portion 82 in the left-right direction. And. The seat grip portion 8 also functions as a detection unit for the wide edge 100a.

As shown in FIG. 30, the base portion 611 of the suction main body portion 61 can be moved in the vertical direction by the elevating device 64. The elevating device 64 includes a moving nut 64a fixed to the side of the base portion 611, a feed screw 64b screwed into the moving nut 64a, a motor 64c for rotating the feed screw 64b, and the motor. It is provided with a belt transmission mechanism 64d that transmits the driving force of 64c to the feed screw 64b, and a guide 64e that stabilizes the raising and lowering of the base portion 611. The vertical position of the suction main body 61 can be adjusted by the lifting device 64.

The suction main body 61 is connected to the base 611 via a guide rail 65e of the front-rear moving device 65. The front-rear movement device 65 moves the suction main body 61 in the front-rear direction (the direction in which the suction main body 61 is close to and separated from the discharge portion 120 of the drug storage cassette 1). The front-rear moving device 65 includes a moving nut 65a fixed to the back surface of the suction main body 61, a feed screw 65b screwed into the moving nut 65a, a motor 65c for rotating the feed screw 65b, and the motor 65c. It includes a belt transmission mechanism 65d that transmits the driving force of the motor 65c to the feed screw 65b.

In the front-rear moving device 65, the moving operation unit 130 in the drug containing cassette 1 is faster than the speed at which the PTP sheet 100 is moved, and the leading PTP is in the direction in which the moving operation unit 130 moves the PTP sheet 100. The suction main body 61 can be moved by sucking the sheet 100.

Further, when the suction main body 61 is moved in the direction approaching the drug storage cassette 1 by the front-back moving device 65, the suction main body 61 comes into contact with the sheet portion of the leading PTP sheet 100 and is adsorbed. When the pocket portion of the leading PTP sheet 100 faces the payout operation portion 110 side, the movable plate 62a of the pocket detection portion 62 is displaced in position according to the convex height of the pocket portion. The position displacement can be detected by, for example, the resistance value (voltage value) of the potentiometer.

As shown in FIGS. 31 (A) and 31 (B), the suction main body 61 includes, for example, four suction cups 61a arranged horizontally. As shown in FIGS. 37 (A), 37 (B) and 37 (C), the four suction cups 61a arranged side by side include a first group consisting of two suction cups on the side close to the seat grip portion 8 and the above. It is divided into a second group consisting of two pieces on the side far from the seat grip portion 8. The suction for each group can be performed by operating the solenoid valve provided on the intake path of each group. When the suction operation is executed only for the first group from the state where all of the four suction cups 61a are off, a strong suction force is generated in the two suction cups 61a of the first group, and the PTP sheet 100 is the first group. It is sucked to two suction cups 61a in one group with high certainty. Then, when the suction operation of the four suction cups 61a of the second group is also executed after the suction operation of the first group is executed, the PTP sheet 100 can be accurately sucked and held by the four suction cups 61a. .. In this way, by driving in advance a part of the suction cups provided (a part on the side close to the seat grip portion 8), the PTP sheet 100 can be accurately sucked and held.

The normal rotation rotation portion 13 includes a suction rotation pipe portion 13a at the center position of the four suction cups 61a arranged side by side. A suction cup portion 13b is provided at the tip of the suction rotary pipe portion 13a. Further, the rear side of the suction rotary pipe portion 13a is supported by the bearing portion 13c. Further, a rotary joint 13d is connected to the rear end of the suction rotary pipe portion 13a, and the rotary joint 13d is connected to the suction pump via a tube. Further, the belt 13e is wound around the rear portion of the suction rotary pipe portion 13a and the drive pulley of the motor 13f. When the motor 13f operates, the suction rotary pipe portion 13a rotates around its central axis. The suction rotary pipe portion 13a is fixed in the front-rear direction.

When the delivery section 3 is moved to the payout position by the delivery section moving section 4, the drug storage cassette 1 chucked by the delivery section 3 faces the suction main body section 61. Then, the operation of opening the lid 140 is executed by the lid opening / closing unit 160. Next, the suction cup 61a moves in a direction approaching the drug containing cassette 1, so that the suction cup 61a comes into contact with the PTP sheet 100 in the drug containing cassette 1 and sucks the PTP sheet 100. Further, at this time, the orientation of the pocket portion of the PTP sheet 100 is detected by the movable plate 62a (see FIGS. 26 and 30) of the pocket detection portion 62. By moving the suction main body 61 away from the payout 120, the leading PTP sheet 100 is pulled out from the drug storage cassette 1.

When suction is executed by the suction main body 61 after all the PTP sheets 100 have been pulled out from the drug storage cassette 1, the suction cup 61a sucks the holding member 131 of the moving operation unit 130. Become. As shown in FIG. 5, a plurality of groove portions 131a are formed on the pressing surface of the pressing member 131 in contact with the PTP sheet 100. Therefore, when the PTP sheet 100 is emptied, the suction cup 61a is subjected to the pressing member. It comes into contact with the pressing surface of 131. In this case, since air leaks from the groove 131a, a predetermined negative pressure state cannot be obtained in the suction circuit of the suction cup 61a even if the suction operation by the suction operation unit 6 is executed. That is, the suction by the suction main body 61 cannot be completed even after a certain period of time has passed. When the suction by the suction main body 61 cannot be completed even after a certain period of time, the control unit 1005 can determine that the PTP sheet 100 may be out of stock. When the suction main body 61 is provided with four suction cups 61a, the number of the groove 131a is sufficient. That is, the groove portions 131a may be provided at least as many as the number of suction cups 61a at positions corresponding to the suction cups 61a.

When a fractional packaging agent is required, if it is determined from the detection result by the movable plate 62a that the pocket portion of the PTP sheet 100 faces the suction cup 61a side, the suction main body portion 61 is PTP. The seat 100 is passed to the seat grip portion 8. The seat grip portion 8 faces the pocket portion toward the drug storage cassette 1. After that, the suction main body 61 receives the PTP sheet 100 from the sheet gripping portion 8.

When the sheet gripping portion 8 grips the PTP sheet 100, it determines whether or not the gripped side is the wide edge 100a of the PTP sheet 100. When the sheet gripping portion 8 grips the wide edge 100a, the normal rotation rotating portion 13 does not rotate around the normal line, and the suction main body 61 approaches the drug containing cassette 1. Moving in the direction, the PTP sheet 100 is dropped onto the sheet storage section 141 of the lid 140. The wide edge 100a of the PTP sheet 100 dropped onto the sheet storage section 141 faces the side of the sheet gripping section 14 described later, and the side opposite to the wide edge 100a is the cutter section provided in the payout operation section 110. It will turn to the side of 15. Even when the pocket portion of the PTP sheet 100 faces the drug storage cassette 1 side, the suction main body portion 61 passes the PTP sheet 100 to the seat grip portion 8 for detecting the wide edge 100a. However, in this case, the PTP sheet 100 is not rotated by the seat gripping portion 8.

On the other hand, when the sheet gripping portion 8 grips the opposite side of the wide edge 100a, the suction main body portion 61 passes the PTP sheet 100 to the normal rotation rotating portion 13. The normal rotation rotation portion 13 rotates the PTP sheet 100 around the normal line so that the direction of the wide edge 100a faces the opposite side by 180 degrees.

Here, as shown in FIG. 8, when the two front and rear PTP sheets 100 in the drug containing cassette 1 face each other on the forming side of the pocket portion, the lower end of the two PTP sheets 100 The upper end position of the PTP sheet 100 in contact with the storage bottom in the drug storage cassette 1 is the original position, while the upper end position of the other PTP sheet 100 is higher than the original position by H. The height H is different for each drug, and the information on the height H is recorded in the master table for each drug. Further, when the pockets of the PTP sheet 100 are in three rows, as shown in FIG. 8, the suction height from the lower end of the sheet is about 1/3 of the height of the PTP sheet 100, and the PTP sheet 100 When the pockets are in an even number row such as two rows or four rows, the suction height is about ½ of the height of the PTP sheet 100. The suction height varies from drug to drug and is recorded on the master table. The information on the height H and the information on the suction height can be used at the time of paying out the PTP sheet 100 by the suction main body 61.

When the PTP sheet 100 does not direct the pocket portion toward the suction main body portion 61, the first suction try regardless of whether or not the PTP sheet 100 is in contact with the storage bottom portion in the drug storage cassette 1. The suction is almost certainly successful, and the PTP sheet 100 can be taken out from the drug containing cassette 1. However, when the PTP sheet 100 is not in contact with the storage bottom in the drug storage cassette 1, the suction position of the suction cup 61a is lower than the original suction height of the PTP sheet 100, which is the original position. .. Then, in this case, after the PTP sheet 100 is rotated around the normal line by the normal rotation unit 13 so that the direction of the wide edge 100a faces 180 degrees in the opposite direction, the PTP sheet 100 is moved. When passed to the suction main body 61, the distance from the suction position of the suction cup 61a to the lower end of the PTP sheet 100 becomes longer than when suction can be performed at the suction height which is the original position.

As described above, when the suction main body 61 executes the moving operation for dropping the PTP sheet 100 onto the sheet storage unit 141 when the suction position is not the original position, the lower end of the PTP sheet 100 is moved. , There is a risk of contacting the upper end 143 of the wall portion at the entrance of the sheet storage portion 141 shown in FIG. Therefore, in a series of processes for dropping the PTP sheet 100 onto the sheet storage unit 141, when the operation of turning the wide edge 100a in the opposite direction by 180 degrees is executed, the chemical sheet generated by the rotation of 180 degrees Performs processing to eliminate (absorb) fluctuations in the lower edge position.

The process of eliminating the fluctuation may be an operation of moving the suction main body 61 upward by a constant distance or a non-constant distance as compared with the case where the operation of turning the wide edge 100a in the opposite direction by 180 degrees is not executed. .. By this movement, it is possible to prevent the lower end of the PTP sheet 100 from coming into contact with the upper end 143 of the wall portion at the entrance of the sheet storage unit 141.

When the above-mentioned constant distance is adopted, the PTP sheet 100 of any drug is moved upward by the above-mentioned constant distance. On the other hand, the non-constant distance is, for example, the height H or a distance in which a margin is added to the height H, and in this case, the PTP sheet 100 is moved upward by a different distance for each drug. Both the movement of the constant distance and the movement of the non-constant distance are movement operations of the suction main body 61 that absorbs the misalignment of the PTP sheet 100 in the drug storage cassette 1. The misalignment of the PTP sheet 100 in the drug storage cassette 1 is when the two front and rear PTP sheets 100 in the drug storage cassette 1 face each other on the pocket forming side, as described above. Occurs in.

If the PTP sheet 100 that is not in contact with the bottom of the drug storage cassette 1 is located at the front and the pocket portion is directed toward the suction main body 61, the first suction try may fail. For example, if the suction cup 61a hits the pocket portion and a gap is formed, the suction cannot be completed. If suction cannot be completed even after a certain period of time, it is judged as a failure. In this case, for example, after moving the movable plate 62a of the pocket detection unit 62 forward, it moves downward by a constant distance or a non-constant distance. By this movement, the other PTP sheet 100 can be brought into contact with the storage bottom in the drug storage cassette 1 by the movable plate 62a, and the PTP sheet 100 is sucked with almost no failure in the next suction try. Can be taken out from the drug containing cassette 1. A second try may be performed after the first failure, and when it is determined that the failure has also occurred, the movable plate 62a or the like may be moved downward by a constant distance or a non-constant distance.

When the above-mentioned constant distance is adopted, any PTP sheet 100 is moved downward by the above-mentioned constant distance. On the other hand, the non-constant distance is, for example, the height H or a distance in which a margin is added to the height H, and in this case, the PTP sheet 100 is moved downward by a different distance for each drug.

Further, as shown in FIG. 8, when the two front and rear PTP sheets 100 in the drug containing cassette 1 face each other on the forming side of the pocket portion, the horizontal edges of the two PTP sheets 100 It happens that they do not match.

Here, as described above, when the PTP sheet 100 is gripped, the seat gripping portion 8 determines whether or not the gripped side is the wide edge 100a of the PTP sheet 100. The sheet gripping portion 8 is movable in the lateral direction, and is provided with, for example, an optical sensor 801 as shown in FIG. 40 in order to detect the lateral edge of the PTP sheet 100. When the optical sensor 801 detects the lateral edge, the sheet gripping portion 8 stops the lateral movement in the direction approaching the PTP sheet 100 and starts the operation of gripping the PTP sheet 100. As a result, even if the taken out PTP sheets 100 are displaced in the lateral direction due to the fact that the horizontal edges of the two PTP sheets 100 do not match, the sheet gripping portion 8 can be moved by the detection of the horizontal edges. The PTP sheet 100 can be appropriately gripped.

On the other hand, when the suction main body 61 executes a moving operation for dropping the PTP sheet 100 onto the sheet storage unit 141 in the presence of the lateral displacement, the PTP sheet 100 is shown in FIG. There is a risk of failure to put it in the above-mentioned sheet storage unit 141 shown. Therefore, when the sheet gripping portion 8 receives the PTP sheet 100 from the suction main body 61 and then passes the PTP sheet 100 to the suction main body 61 again, the sheet gripping portion 8 is displaced in the lateral direction. Move laterally to eliminate.

Specifically, the master table contains information such as the distance d from the center of the PTP sheet 100 to the lateral edge of the sheet (for example, the number of motor pulses required for the sheet gripping portion 8 to move) for each drug. Can be indicated by.) Is recorded. Further, for example, a stepping motor is used for the lateral movement, and it is possible to determine how far the seat grip portion 8 has moved from the reference position. Further, the distance D from the reference position to the center of the dispensing portion 120 of the drug containing cassette 1 (the axial position of the rotating portion 13 around the normal line) is known. Therefore, if the optical sensor 801 cannot detect the lateral edge of the seat at a position where the seat gripping portion 8 moves a distance obtained by subtracting the distance d from the distance D, a lateral displacement occurs. It can be judged that there is. Therefore, when the sheet gripping portion 8 receives the PTP sheet 100 from the suction main body 61 and then passes the PTP sheet 100 to the suction main body 61 again, the sheet gripping portion 8 is displaced in the lateral direction. Adjusts and moves in the horizontal direction by the amount of. As a result, the lateral deviation is eliminated. After the sheet gripping portion 8 receives the PTP sheet 100 from the suction main body portion 61, the seat gripping portion 8 may return to the reference position once and move in the lateral direction at a distance obtained by subtracting the distance d from the distance D. ..

The sheet gripping portion 14 is provided so as to be movable in the left-right direction of the drug dispensing device 101. The sheet gripping section 14 grips the wide edge 100a of the PTP sheet 100 dropped on the sheet storage section 141, and moves the PTP sheet 100 toward the cutter section 15. The cutter portion 15 includes a fixed blade 15a and a movable blade 15b, and can cut the PTP sheet 100 in an L shape. After this cutting, the sheet gripping section 14 moves the PTP sheet 100 to the side of the sheet storage section 141, and places the PTP sheet 100 on the sheet storage section 141. Further, the fractional packaging agent obtained by the above cutting falls on the belt conveyor 15c. The fractional packaging agent is conveyed by the belt conveyor 15c, passes through the notch 1121 (see FIG. 24) formed in the hopper portion 112a of the sheet stocker 112, and falls into the hopper portion 112a.

When it is necessary to take out a plurality of PTP sheets 100 based on the prescription data, the suction main body 61 moves from the drug storage cassette 1 to the PTP sheet in parallel with the operation of cutting out a fractional packaged drug. The operation of taking out 100 is repeated, and the taken out PTP sheet 100 is sequentially dropped into the sheet stocker 112. In this way, if the operation of taking out the PTP sheet 100 from the drug containing cassette 1 is performed in parallel with the process of cutting out the fractional packaged drug, the time required for paying out can be shortened.

For example, the operation of setting the PTP sheet 100 for cutting out fractions in the sheet storage unit 141 is performed on the PTP sheet 100 first taken out from the drug storage cassette 1. Then, the first process of cutting out a fraction of the packaging drug from the PTP sheet 100 set in the sheet storage unit 141, and the second process of taking out the required number of PTP sheets 100 from the drug storage cassette 1 by the suction main body 61. In parallel. Even when the PTP sheet 100 taken out from the second time onward instead of the first is set in the sheet storage unit 141, the first process and the second process can be performed in parallel. In addition, the PTP sheet 100 for cutting out fractions or some fractional packaging agents already remain in the sheet storage unit 141, and when fractional cutting is performed using this, the second process is executed during that period. When the inside of the sheet storage unit 141 becomes empty during the second processing, the second processing is temporarily stopped and the PTP sheet 100 for fraction cutting is set in the sheet storage unit 141. May be done.

Further, when a process of paying out a plurality of PTP sheets 100 is required based on the prescription data and a PTP sheet 100 for cutting out fractions is also required, the following processing may be performed. For example, the orientation of the wide edge 100a of the PTP sheet 100 first taken out from the drug containing cassette 1 is detected by the sheet gripping portion 8. Then, when the wide edge 100a does not face a predetermined direction, the first PTP sheet 100 is dropped and discharged. The same process is performed on the subsequent PTP sheet 100.

Here, for example, when it is necessary to pay out three PTP sheets 100 and a fractional packaging agent, if the orientation of the wide edge 100a of the third PTP sheet 100 taken out is a predetermined orientation, the present invention is concerned. The third PTP sheet 100 taken out is set in the sheet storage unit 141. That is, the PTP sheet 100 taken out from the third sheet is used as the PTP sheet 100 for cutting out fractions. Since the number of PTP sheets 100 to be paid out is three, the PTP sheet 100 is subsequently taken out from the drug containing cassette 1 and paid out.

On the other hand, when the wide edge 100a of the PTP sheet 100 taken out from the third sheet does not face a predetermined direction, the PTP sheet 100 taken out from the third sheet is dropped and paid out. Then, the fourth PTP sheet 100 is taken out from the drug containing cassette 1. When the wide edge 100a of the fourth PTP sheet 100 does not face a predetermined direction, the PTP sheet 100 is rotated by the normal rotation unit 13 and set in the sheet storage unit 141.

That is, when it is necessary to store the PTP sheet 100 in a predetermined direction in the sheet storage unit 141 for fraction cutting provided in the drug storage cassette 1, a plurality of PTPs taken out from the drug storage cassette 1 are taken out. The PTP sheet 100 facing a predetermined direction in the sheet 100 is housed in the sheet storage unit 141. Then, when all the taken out PTP sheets 100 are not oriented in a predetermined direction, the last PTP sheet 100 is rotated by the normal rotation rotation unit 13 which is a rotation operation unit.

According to the above method, the rotation operation of the PTP sheet 100 by the rotation operation unit can be reduced as much as possible, so that the time required for the drug dispensing process can be shortened. In this case, the mechanical detection operation by the sheet gripping portion 8 for detecting the orientation of the wide edge 100a of the PTP sheet 100 may increase. Here, if the configuration is such that the orientation of the wide edge 100a of the PTP sheet 100 taken out from the drug containing cassette 1 is detected by the image sensor, the mechanical detection operation is unnecessary and the image processing speed is improved. You can save time.

In the above method, among the plurality of PTP sheets 100 taken out from the drug storage cassette 1, the PTP sheet 100 in which the orientation of the wide edge 100a and the orientation of the pocket portion are both predetermined directions is used in the sheet storage unit 141. It may be accommodated in. Then, when one or both of the orientation of the wide edge 100a and the pocket portion of all the taken out PTP sheets 100 are not oriented in a predetermined orientation, the normal rotation portion 13 and the normal rotation portion 13 which are the rotation operation portions and the pocket portion are not oriented. / Or the last PTP sheet 100 is rotated by the sheet gripping portion 8. The pocket portion of the PTP sheet 100 taken out from the drug containing cassette 1 can also be detected by the image sensor.

In the above embodiment, the pockets and wide edges of the drug sheet taken out from the drug storage cassette are oriented in the same direction, but the user sets the drug sheet in the drug storage cassette by aligning the pockets. In the case, the configuration may omit the means for detecting the pocket and the means for reversing the direction of the pocket.

Further, if at least the wide edge of the drug sheet taken out from the drug storage cassette can be oriented in the same direction, it is possible to cut the fraction of the drug sheet even if the pocket orientations are not the same.

Here, an operation example for paying out the PTP sheets 100 one by one is shown. In this operation example, the suction main body 61 sucks the head PTP sheet 100 in the accommodating portion 11 and pushes the PTP sheet 100 in the direction opposite to the moving direction of the PTP sheet 100 by the moving operation unit 130. Then, the PTP sheet 100 is pulled in the same direction as the moving direction at a speed faster than the moving speed of the PTP sheet 100 by the moving operation unit 130. As a result, the contact member 121a of the first limiting portion 121 is positioned between the first PTP sheet 100 and the second PTP sheet 100, and only the first PTP sheet 100 is paid out.

In the front-rear moving device 65, after the moving operation unit 130 moves the suction operation unit (take-out unit) 6 in the direction opposite to the direction in which the PTP sheet 100 is moved (by the operation of pushing in the opposite direction). The moving operation unit 130 moves in the opposite direction), the moving operation unit 130 is faster than the speed at which the PTP sheet 100 is moved, and the moving operation unit 130 moves the PTP sheet 100 in the direction. It is desirable to move the suction operation unit 6 holding the PTP sheet 100 at the head. In this way, by moving the suction main body 61 in the direction opposite to the direction in which the moving operation unit 130 moves the PTP sheet 100, the leading PTP sheet 100 and the first PTP sheet 100 are paid out when the PTP sheet 100 is paid out. 1 The distance from the limiting portion 121 can be increased. As a result, the time from when the suction main body 61 starts moving the leading PTP sheet 100 until the leading PTP sheet 100 gets over the first limiting section 121 increases. Therefore, even if the difference between the speed at which the suction main body 61 moves the PTP sheet 100 and the speed at which the moving operation unit 130 moves the PTP sheet 100 is small, the leading PTP sheet 100 passes through the first limiting unit 121. At that time, the distance between the first PTP sheet 100 and the second PTP sheet 100 can be increased, and the first limiting portion 121 can easily enter between the first PTP sheet 100 and the second PTP sheet 100. Become.

The suction main body 61 sucks the leading PTP sheet 100 in the accommodating portion 11 and pushes the PTP sheet 100 in the direction opposite to the moving direction of the PTP sheet 100 by the moving operation unit 130. The suction of the PTP sheet 100 by the suction main body 61 is surely executed.

[Tray moving part 500]
The tray moving unit 500 does not have to exist in the type in which the drug dispensing device is configured by one drug dispensing device 101. When the tray moving unit 500 is provided, another drug dispensing device 101 can be placed on the tray moving unit 500, and the drug tray T can be moved between a plurality of drug dispensing devices. As shown in FIG. 1, the tray moving unit 500 has a conveyor unit 51 that moves the medicine tray T in the left-right direction of the medicine dispensing device 101. As shown in FIGS. 32 (A) and 32 (B), the conveyor portion 51 includes two moving belts 51b on both sides of the monorail portion 51a extending in the left-right direction. The medicine tray T is placed on the moving belt 51b so that the recess C formed at the bottom thereof engages with the monorail portion 51a. The moving belt 51b is driven by a motor 51c. Since the drug tray T has a structure guided by the monorail portion 51a, the structure can be simplified. The recess C is formed by utilizing the formation of the accommodating recesses T1, T2, T3, and T4, but the present invention is not limited to this. For example, as shown in FIG. 4B, a drug tray T in which one storage recess T11 is formed can also be used. The medicine tray T is provided with two legs T10 on the lower surface of the tray main body, and a recess C into which the monorail portion 51a is inserted is formed between the legs T10. Even if the drug tray T does not have a plurality of accommodating recesses, the drug can be arranged at appropriate positions on the front, back, left and right of the drug tray T by moving the drug tray T back and forth and left and right by the conveyor portion 51. ..

Further, the conveyor unit 51 is moved in the front-rear direction of the drug dispensing device 101 by the front-rear drive unit 52. The front-rear drive unit 52 is provided with a feed screw 52a in the front-rear direction. A moving nut is provided on the base portion of the conveyor portion 51, and the feed screw 52a is screwed into the moving nut. When the feed screw 52a is rotated by the motor 52b, the conveyor portion 51 is moved in the front-rear direction. Further, the conveyor portion 51 is guided in the front-rear direction by the guide shaft 52c.

The conveyor portion 51 is provided with a positioning portion 53. The positioning unit 53 uses the driving force of one motor 53a to rotate a shaft (support shaft) 53b provided in the left-right direction of the drug dispensing device 101, thereby rotating the drug tray 53 at a plurality of positions. T can be positioned. The positioning unit 53 includes six stopper members 531 operated by the shaft 53b. Two fixed stopper portions 532 that do not move together with the conveyor portion 51 are provided at both left and right ends of the tray moving portion 500.

As shown in FIG. 33, the main body portion 531a of each stopper member 531 is provided with a rotating portion 531b rotatably. The rotating portion 531b can rotate when it comes into contact with the side surface of the drug tray T that moves in the left-right direction of the drug dispensing device 101. Further, a shaft insertion hole 531c is formed in the main body portion 531a, and the shaft 53b is inserted into the shaft insertion hole 531c. Each stopper member 531 is rotatably provided with respect to the shaft 53b.

The fixing portion 531e provided separately from the main body portion 531a is fixed to the shaft 53b. Then, one end of the winding spring 531d wound around the shaft 53b is engaged with the fixing portion 531e, and the other end is engaged with the main body portion 531a, so that the stopper member 531 rotates in the same body as the shaft 53b. Move. When the stopper member 531 tilts in the traveling direction of the drug tray T due to the same body rotation, the movement of the drug tray T is blocked and positioning is performed. On the other hand, when the rotating portion 531b hits the side surface of the medicine tray T when the stopper member 531 is tilted, the state in which the main body portion 531a hits the side surface of the medicine tray T against the winding spring 531d is maintained. Then, the rotating portion 531b rotates and does not prevent the drug tray T from moving.

That is, the positioning unit 53 stands up by the rotation of the shaft 53b in the first rotation direction to allow the drug tray T to pass through, while tilts by the rotation of the shaft 53b in the second rotation direction. The plurality of stopper members 531 that prevent the passage of the drug tray T and the stopper member 531 that hits the side surface of the drug tray T when the shaft 53b rotates in the second rotation direction are non-tilted. A winding spring 531d (elastic member) that allows the above.

For example, when the drug tray T is detected by a sensor (not shown) in front of the target positioning point, the motor 53a is operated to rotate the shaft 53b to position the drug tray T at the target positioning point. You can stop with. As described above, while the plurality of stopper members 531 operate in the same body to position the medicine tray T, some of the plurality of stopper members 531 do not operate in the same body and do not function as stoppers. This structure is realized by one motor 53a and one shaft 53b, and the structure is simplified.

The tray moving portion 5 includes the conveyor portion 51 and the fixed conveyor portion 55. That is, the tray moving portion 5 corresponds to a structure in which the tray moving portion 500 is provided with a fixed conveyor portion 55 on the front side of the conveyor portion 51 (front side of the drug dispensing device 101) (see FIG. 1). ). The conveyor portion 55 is not provided with the positioning portion 53. The conveyor section 55 can receive an empty drug tray T from the tray stocker 1012 and pass the empty drug tray T to the conveyor section 51 of the tray moving section 500. The tray moving unit 500 that has received the empty drug tray T moves the conveyor section 51 backward, and passes the empty drug tray T to the conveyor section 51 of the tray moving section 5. By providing the tray moving unit 500, it is possible to operate a plurality of medicine trays T, such as keeping the medicine tray to be used in the next payout on the tray moving unit 500.

The tray moving unit 5 is provided so as to be movable in the front-rear direction of the drug dispensing device 101 on the lower side of the dispensing operation unit 110 so that the tray moving unit 5 can be pulled out from the lower position of the dispensing operation unit 110 to the front side of the device. It has become.

FIG. 34 shows the positions of the stopper member 531 on the conveyor section 51 of the tray moving section 5, the positions of the sheet stockers 112 of the first payout operation section 110 and the second payout operation section 110, and the positions of the two sheet stockers 112. All the stop positions from the right side and the left side when the four storage recesses T1, T2, T3, and T4 of the drug tray T are aligned with the positions are shown. In this stop position example, in order to make the drug dispensing device compact, the interval between the positions where the drug tray T is desired to be stopped (the interval between the arrangement of the stopper member 531) is shorter than the tray size in the transport direction of the drug tray T. Illustrate. In order to realize this exemplary configuration, the positioning portion 53 is provided so that the rotation of the shaft 53b is ensured even when the stopper member 531 located on the side surface of the drug tray T hits the side surface of the tray. The stopper member 531 functions as a stopper.

As can be seen from FIG. 34, the positioning portion 53 requires eight stopper members. In this embodiment, as described above, six stopper members 531 operated by the shaft 53b are provided, and two fixed stopper portions 532 are provided. When the conveyor section 51 is moved to the rear side of the drug dispensing device, the fixed stopper section 532 does not become an obstacle, and the drug tray is placed between the tray moving section 500 and the tray moving section 5. T can move.

The case where the PTP sheet 100 cannot be pulled out by the suction operation unit 6 includes a case where the inside of the drug containing cassette 1 is empty (out of stock) and a case where the suction is poor. In this embodiment, for example, a weighing scale for measuring the weight of the drug storage cassette 1 is provided in each payout operation unit 110, and when the drug storage cassette 1 is gripped, the number of PTP sheets 100 stored ( Inventory) can be determined. Therefore, when the PTP sheet 100 is discharged from the drug containing cassette 1 which is determined to be in stock and the suction operation unit 6 cannot pull out the PTP sheet 100, the following processing can be performed. That is, if it is determined that the product is in stock and suction cannot be performed, it is determined that a suction defect has occurred and error processing is executed. If it is determined that the product is empty (out of stock) and suction cannot be performed, it indicates that the product is out of stock. Perform error handling. This makes it possible to inform the user of the exact state of the device 101. In addition, when it is set to continue the payout process without causing an error in the case of a missing item, if it is not a missing item, a process such as stopping the device by an error process can be appropriately performed.

It may be prohibited for a specific drug that the two front and rear PTP sheets 100 in the drug storage cassette 1 are set so that the forming sides of the pocket portions face each other. For example, it is prohibited to use a drug that causes poor suction because the two PTP sheets 100 are strongly bonded to each other. Such prohibited information can be registered in the above master table for each drug. When the drug containing cassette 1 containing the drug for which the prohibition information is set is selected as the drug replenishment target, as shown in FIG. 38, the control unit 1005 sets the PTP sheet 100 on the display 1002. A message calling attention can be displayed. For example, "It is prohibited to set this medicine sheet on the cassette so that the pockets face each other. When setting the medicine sheet on the cassette, be sure to point the medicine sheet in a certain direction." Display a message. The drug storage cassette is selected by reading the drug storage cassette ID from the barcode printed on the drug storage cassette or the information recording unit (for example, RFID tag: radio frequency identifier tag, etc.) held in the drug storage cassette. .. Not only when the drug storage cassette 1 is selected as the drug replenishment target, but also when a specific drug is selected, for example, a barcode printed on the PTP sheet 100 or a plurality of PTP sheets 100 are packaged. A message as shown in FIG. 38 may be displayed when the barcode printed on the box or the like is read.

Further, when the control unit 1005 executes the error processing due to the occurrence of the suction failure, if this error occurs in the drug storage cassette 1 of the specific drug, the PTP sheet is displayed on the display 1002 together with the error display. A message calling attention to 100 sets can be displayed. For example, a message such as "It is prohibited to set this medicine sheet in the cassette so that the pockets face each other. Make sure that the medicine sheet is oriented in the same direction." Is displayed.

For example, as shown in the flowchart of FIG. 39, the control unit 1005 uses the weight scale to determine whether or not the product is out of stock when a suction failure occurs in a certain drug storage cassette 1 (step S1). ), When it is determined that the product is out of stock, a message prompting the replenishment of the PTP sheet 100 is displayed (step S2). When it is determined that the product is not out of stock, it is determined whether or not the drug set in the drug storage cassette 1 is a specific product (step S3). If it is not a specific product, a message indicating a normal error is displayed (step S4). On the other hand, in the case of a specific product, an error is displayed and a message indicating that free setting is prohibited is displayed (step S5). The message portion indicating that the prohibition is prohibited can be the same as the message content shown in FIG. 38. In step S1, a message is also displayed when a shortage occurs in the drug containing cassette 1 of a specific product, and this message display can be the same as the message content shown in FIG. 38.

In the above embodiment, the suction operation unit 6 is shown as the take-out unit holding the PTP sheet 100, but the suction is not limited to such suction, and the leading PTP sheet 100 in the drug storage cassette 1 is adhered or gripped. You may pay it out.
