In FIG. 3, the horizontal axis represents time and the vertical axis represents the operation content of each unit. Since there is only one cassette carrying section 2, a series of operations for supplying the medicine containing cassette 1 to the four delivery sections 3 is repeated four times in order to pay out the four types of PTP sheets 100. Further, a series of operations for receiving the medicine containing cassette 1 from the four delivery units 3 and returning it to the cassette shelf 1011 is repeated four times.

  Here, in this embodiment, the first delivery section 3 receives the first drug storage cassette 1 that stores the first drug that is taken out first, and stores the second drug that is taken out second. The third delivery section 3 receives the first drug storage cassette 1, the second delivery section 3 receives the third drug storage cassette 1 containing the third drug to be taken out third, and the third delivery section 3 receives the third drug storage cassette 1 taken out fourth. The fourth delivery section 3 receives the fourth drug storage cassette 1 that stores the fourth drug stored therein.

  Based on the prescription data, the four kinds of medicines to be dispensed may be defined as the first medicine, the second medicine, the third medicine, and the fourth medicine in descending order of the number of medicines to be dispensed. Alternatively, based on the prescription data, the four kinds of medicines to be dispensed may be defined as the first medicine, the second medicine, the third medicine, and the fourth medicine in descending order of the number of packaged medicines. Good. Alternatively, based on the prescription data, the four types of drugs to be dispensed are defined as the first drug, the second drug, the third drug, and the fourth drug in the order in which the time required for the dispensing is estimated to be long. You may do it. When the number of PTP sheets 100 to be dispensed and the number of fractions of packaging medicine are large, it can be estimated that the time required for dispensing is long. Alternatively, a number is assigned to each container of the cassette shelf 1011 and defined as the first drug, the second drug, the third drug, and the fourth drug in ascending order of the container numbers. May be. Alternatively, the first drug, the second drug, the third drug, and the fourth drug may be defined in the order of description of the four drugs described in the prescription data.

Then, the second dispensing operation unit 110 starts an operation of dispensing the PTP sheet 100 as the fourth medicine from the fourth medicine storage cassette 1. Further, the cassette loading / unloading section 21 that has delivered the fourth medicine storage cassette 1 to the fourth delivery section 3 is separated from the fourth delivery section 3.

  The dispensing operation section 110 cannot receive the next medicine unless the PTP sheet 100 stored in the sheet stocker 112 is discharged from the medicine sheet outlet section 1120. Therefore, the control unit 1005 controls the tray moving unit 5 to position the accommodation recess T1 of the medicine tray T below the medicine sheet outlet of the first dispensing operation unit 110. Further, the control unit 1005 completes the operation of the first dispensing operation unit 110 to dispense the designated number of the first medicine, and completes the operation of positioning the accommodation recess T1 below the medicine sheet outlet portion 1120. Under the above condition, the sheet stocker 112 in the first dispensing operation unit 110 is opened, and the PTP sheet 100 as the first medicine is discharged into, for example, the accommodation recess T1. Note that after the first medicine is dispensed and the first delivery unit 3 is moved to the standby position, the second delivery unit 3 is moved from the standby position to the dispensing position.

  Further, the control unit 1005 controls the tray moving unit 5 to position the accommodation recess T2 of the medicine tray T below the medicine sheet outlet of the second dispensing operation unit 110. Then, the control unit 1005 completes the operation of the second dispensing operation unit 110 to dispense the designated number of second medicines, and completes the operation of positioning the storage recess T2 below the medicine sheet outlet portion 1120. Under the above condition, the sheet stocker 112 in the second dispensing operation unit 110 is opened, and the PTP sheet 100 as the second medicine is discharged into the accommodation recess T2.

  When the release of the PTP sheet 100 as the first medicine by the first dispensing operation unit 110 is completed, the control unit 1005 controls the first dispensing operation unit 110 to dispense the designated number of the third medicine. Then, the control unit 1005 completes the operation of the first dispensing operation unit 110 to dispense the designated number of the third medicine and completes the operation of positioning the accommodation recess T3 below the medicine sheet outlet. Under the above condition, the sheet stocker 112 in the first dispensing operation unit 110 is opened, and the PTP sheet 100 serving as the third medicine is discharged into the accommodation recess T3.

  Further, when the second dispensing operation unit 110 completes the ejection of the PTP sheet 100 as the second drug, the control unit 1005 controls the second dispensing operation unit 110 to dispense the specified number of fourth drugs. Then, the control section 1005 completes the operation of the second dispensing operation section 110 for dispensing the designated number of the fourth medicine, and completes the operation of positioning the accommodation recess T4 below the medicine sheet outlet section. Under the above condition, the sheet stocker 112 in the second dispensing operation unit 110 is opened, and the PTP sheet 100 serving as the fourth medicine is discharged into the accommodation recess T4.

  The control unit 1005 controls the tray moving unit 5 to transfer the drug tray T that has received the four types of drugs to the stacking unit of the tray stocker 1012.

  Further, the control unit 1005 controls the cassette transport unit 2 to execute a process of returning the medicine storage cassette 1 waiting at the delivery position after the delivery of the PTP sheet 100 is completed to the cassette shelf 1011. This returning process can be performed in the order of, for example, the first drug storage cassette 1, the second drug storage cassette 1, the third drug storage cassette 1, and the fourth drug storage cassette 1. Alternatively, it is possible to preferentially return the medicine containing cassette 1 waiting at the delivery position closest to the place of the medicine containing cassette 1 returned to the cassette shelf 1011 to the cassette shelf 1011.

  Here, for example, the first medicine storage cassette 1, the second medicine storage cassette 1, and the third medicine storage cassette 1 are sequentially transferred to the delivery unit 3 at the time of sequentially carrying the first medicine. When the medicine dispensing of the accommodation cassette 1 is completed, the first medicine accommodation cassette 1 is transferred to the fourth delivery unit 3 before the first medicine accommodation cassette 1 is transferred. It is conceivable to execute processing for returning to 1011. However, in such a process, even though the medicine dispensing in the second medicine accommodating cassette 1 is temporarily finished and the medicine dispensing in the fourth medicine accommodating cassette 1 can be started, the fourth medicine accommodating cassette 1 can be started. It may happen that the medicine dispensing cannot be started in the accommodation cassette 1. With this, the time required for the dispensing process of the plurality of drug sheets becomes long.

  In the operation example shown in FIG. 3, the delivery of the drug storage cassette 1 to the four delivery units 3 is sequentially repeated, and then the drug storage cassette 1 in which the delivery of the PTP sheet 100 is completed is delivered from the delivery unit 3. The carrying back to the cassette shelf is sequentially repeated. According to this, when the medicine dispensing in the second medicine housing cassette 1 is completed and the medicine dispensing in the fourth medicine housing cassette 1 can be started, the medicine dispensing in the fourth medicine housing cassette 1 is immediately performed. You can start. Therefore, it is possible to shorten the time required for the dispensing process of a plurality of drug sheets.

  Next, the medicine storage cassette 1, the cassette loading / unloading section 21, the moving mechanism 22, the delivery section 3, the dispensing operation section 110, the delivery section moving section 4, and the tray moving section 5 , Each structure example will be described.

[Drug storage cassette]
As shown in FIG. 5 and FIG. 6, the dispensing unit 120 of the medicine containing cassette 1 is provided with first limiting units 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 pass over 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 biases the contact member 121a in a direction in which the PTP sheet 100 is stopped are provided.

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

  The upper first restricting portion 121 is provided in an upper and lower 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 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 body. By moving the dial 123a 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 dispensing 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 medicine storage cassette 1 is provided with a storage size adjusting mechanism in which the storage size is changed by the movement of the size adjusting member and the adjustment position of the size adjusting member corresponding to the storage size is indicated. Good. For example, the numbers for accommodating sizes of 1 to 3 are printed or engraved in the vertical direction on the side supporting the dial 123a, and the upper frame portion 123 as the size adjusting member that moves by the rotation of the dial 123a is arrowed. The mark is printed or engraved so as to indicate the number of the accommodation size. The arrow mark indicates the number of the accommodation size that is currently set. When the operator turns the dial 123a and the arrow mark indicates "3" of the accommodation size, the upper frame portion 123 is set to the third accommodation size.

  The master table stores size information for each medicine. For example, if the medicine A is stored in the 25th medicine storage cassette 1 and the size information about the height of the PTP sheet 100 of the medicine A is “2”, the control unit 1005 displays the above information on the display 1002. It is displayed that the size information about the height of the PTP sheet 100 of the medicine A is “2”. When “2” is displayed on the display 1002 as the size information about the height of the PTP sheet 100 of the medicine A, the operator indicates that the arrow mark in the medicine accommodating cassette 1 of 25 is “2”. The dial 123a is turned to point. Accordingly, even if the operator 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 medicine A.

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

  Separately from the first limiting portion 121, second limiting portions 122 are provided at two left and right positions so as to contact 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 dispensing portion 120. The left and right edges of the leading PTP sheet 100 come into contact with the second limiting portion 122. A V-groove-shaped locking portion 122a capable of sandwiching the left and right edges of the PTP sheet 100 in the accommodation portion 11 is formed at the tip of the second limiting portion 122, and the leading PTP sheet is formed. The movement of 100 is restricted by the left and right edges thereof being locked by the locking portions 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 housing portion 11. A notch is formed in 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 go too deep into the V-shaped groove.

  As shown also in FIG. 8, the PTP sheet 100 is accommodated in the accommodation section 11 of the medicine accommodation cassette 1 such that the long side is lateral and the short side is longitudinal. Therefore, the first limiting portion 121 contacts the long side edge of the PTP sheet 100, and the second limiting portion 122 contacts the short side edge of the PTP sheet 100.

  As shown in FIG. 9, the left and right guide side plates 125 are provided with urging portions 126, respectively. The urging portions 126 urge the guide side plates 125 so that the left and right guide side plates 125 are closer to each other on the leading end side (the side closer to the payout part 120). The rear end side of the guide side plate 125 is engaged with the left and right upright plates of the cassette body, and the urging portion 126 is located between the upright plate and the guide side plate 125. Further, the urging portion 126 regulates the angle formed with the guide side plate 125 by the position of the angle regulating member 126b fitted in the saw-toothed concavo-convex portion 126a in the moving direction of the PTP sheet 100. The angle regulating member 126b is movable in the moving direction of the PTP sheet 100 with respect to the saw-toothed concavo-convex portion 126a. The farther the angle regulating member 126b is moved from the payout portion 120, the larger the maximum angle formed by the biasing portion 126 and the guide side plate 125 becomes, 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 the left and right edges of the PTP sheet 100 are not in contact with the guide side plates 125 on the rear end sides of the left and right guide side plates 125, the left and right guide side plates 125 have front end portions. The leading PTP sheet 100 is guided in contact with the guide side plate 125, and is guided to the center of the payout portion 120. That is, it is possible to store a plurality of types of PTP sheets 100 having different width sizes by using the drug storage cassette 1 having a common structure.

  Further, for example, numbers of accommodation sizes of 1 to 3 are printed or stamped in the vicinity of the saw-toothed concavo-convex portion 126a, and are currently set by the location where the angle regulating member 126b as a size adjusting member is located. The contained size number may be shown to the operator. When the operator adjusts the angle regulating member 126b to the position "3", the guide side plate 125 is set to the third accommodation size. The master table stores size information for each medicine. For example, if the medicine A is stored in the medicine storage cassette 1 of No. 25 and the size information about the width of the PTP sheet 100 of the medicine A is “2”, the control unit 1005 displays the medicine on the display 1002. It is displayed that the size information regarding the height of the A PTP sheet 100 is “2”. If it is displayed on the display 1002 that the size information about the width of the PTP sheet 100 of the medicine A is “2”, the operator sets the angle regulating member 126b in the 25th medicine accommodating cassette 1 to “ 2 ”. Thereby, 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 medicine A.

  As shown in FIGS. 10 and 11 (A), the lid 140 of the medicine storage cassette 1 is provided with a sheet storage unit 141 for storing the PTP sheet 100 for fraction cutting.

  As shown in FIG. 11B, a moving operation unit 130 that moves the PTP sheet 100 toward the dispensing unit 120 is provided in the storage unit 11 of the medicine storage cassette 1. The moving operation unit 130 includes, for example, a pressing member 131 that contacts the PTP sheet 100 and a constant force spring (for example, a product name Conston spring) 132. The pressing force of the constant load spring 132 is set so that the PTP sheet 100 does not pass 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 while the moving operation portion 130 is moved to the rear position and locked. When the lock is released after the PTP sheet 100 is set, the pressing operation on the PTP sheet 100 is started. Further, the constant load spring 132 has a winding spring, and the tip of the winding spring is fixed near the payout portion 120. The lock portion 132a is provided with a gear portion 132b. The gear portion 132b meshes with the toothed portion 11a formed on the bottom surface of the housing portion 11, and the movement operation portion 130 is locked by restricting the rotation of the gear portion 132b. Becomes Further, for example, if a damper (for example, an oil damper) 132c is provided on the gear portion 132b, the operating speed of the moving operation unit 130 can be adjusted. In this case, the damper 132c serves as an adjusting unit that adjusts 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. When the PTP sheet 100 is dispensed, the dispensing unit 120 faces a suction body 61 (see FIG. 30) described later. Then, the back wall portion 1411 of the sheet storage portion 141 faces the suction main body portion 61 when the sheet storage portion 141 is moved to the upper side from the time of the payout. A plurality of height adjusting holes 1411a are formed on the upper side of the inner 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 inner 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 accommodated in the sheet storage unit 141, when the lid 140 is rotated, the It is possible to prevent the PTP sheet 100 for a fractional drug from dropping from the sheet storage unit 141.

  For example, in the vicinity of the plurality of height adjusting holes 1411a, numbers of accommodating sizes of 1 to 3 corresponding to the formation heights thereof may be printed or stamped. If the operator sets the mounting position of the height direction limiting plate 142 to "2", the height direction limiting plate 142 is set to the second height. The master table stores the number of the storage size of the sheet storage unit 141 for each medicine. For example, if the medicine A is stored in the medicine storage cassette 1 of No. 25 and the storage size number of the sheet storage unit 141 for the PTP sheet 100 of the medicine A is “2”, the control unit 1005 determines The display 1002 displays that the storage size number of the sheet storage unit 141 in the medicine A is “2”. If it is displayed on the display 1002 that the number of the storage size of the sheet storage unit 141 in the medicine A is “2”, the operator can move the sheet storage unit 141 of the 25th medicine storage cassette 1 to The mounting position of the height direction limiting plate 142 is set to "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 medicine A.

  Further, the side of the medicine containing cassette 1 opposite to the side where the lid 140 is provided is located on the front side of the medicine dispensing apparatus 101, and a cutout portion 11c is formed in the upper part of the front side rising wall 11b. There is. The cassette loading / unloading section 21 of the cassette transporting section 2 is engaged with the rising wall 11b.

[Cassette loading / unloading section 21]

The front-rear moving unit 23 is connected to the cassette gripping unit 24 via the rail unit 25. The front-rear moving portion 23 is connected to the connecting plate 25a of the rail unit 25. The base portion 241 of the cassette grip portion 24 is connected to the slide portion 251 of the rail unit 25.

  13 and 14 show only the front-rear moving section 23. 12, 13 and 14, two pawl operating portions 231 in the front-rear moving portion 23 are drawn, but this does not show that the two pawl operating portions 231 exist, and The advancing state and the retreating state of the individual claw operating unit 231 are shown. Further, the chain type cable guide 23a is also drawn in an advanced state and a retracted state. The section distance between the advanced state and the retracted state is the first distance.

  The claw operating portion 231 is a bifurcated claw 231a arranged such that a forked portion is located parallel to the rising wall 11b, and a portion between the forked portions moves in a plane parallel to the rising wall 11b. So as to rotate the bifurcated claw 231a so as to rotate (for example, a rotary solenoid) 231b, a bracket 231c that supports the rotation driving unit 231b, a moving nut 231d that supports the bracket 231c, and A feed screw 231e with which the moving nut 231d is screwed, and a guide portion 231f for guiding the moving nut 231d are provided. The feed screw 231e is provided in the front-rear direction of the medicine dispensing device 101, and the guide portion 231f guides the moving nut 231d in the front-rear direction. Then, the driving force of the motor 231g is transmitted to the pulley 231i via the belt 231h, and the pulley 231i rotates to rotate the feed screw 231e.

  When the pawl operating portion 231 is located closest to the rising wall 11b, the pawl operating portion 231 is located on the cutout portion 11c, and the bifurcated pawl 231a is rotated by the rotation driving portion 231b. The rising wall 11b is sandwiched between the two forks. Here, if the notch 11c is formed, the height of the bifurcated pawl 231a when the pawl operating portion 231 is engaged with the rising wall 11b can be reduced, so the cassette shelf In 1011, it is possible to narrow the interval between the drug storage cassettes 1 arranged above and below, increase the number of drug storage cassettes 1 that can be loaded, and downsize the drug dispensing device 101. In this embodiment, only the leading portion of the bifurcated claw 231a is configured to cross the rising wall 11b.

  A drug cover 232 is provided below the front-rear moving unit 23. The medicine covering portion 232 includes a medicine covering plate 232a. The medicine cover plate 232a is located so as to cover the upper side of the medicine accommodating cassette 1 pulled out by this movement when the bifurcated claw 231a moves to the retracted position (when it moves the first distance). When the bifurcated claw 231a moves to the retracted position, the bifurcated claw 231a rotates and returns to the original state (non-engaged state). Therefore, the drug cover plate 232a should be prevented from hindering this return. A notch 232b is formed in the. The medicine cover plate 232a is rotatably provided by a hinge 232c, and the medicine cover plate 232a is attached in a direction in which the PTP sheet 100 in the medicine storage cassette 1 is pressed by a winding spring 232d which is an urging member. Energized. By providing the medicine covering portion 232, when the medicine storing cassette 1 is conveyed by the cassette conveying portion 2 (especially when moving downward at a high speed), the PTP sheet is fed from the upper side of the medicine storing cassette 1. It is possible to prevent 100 from jumping out. In other words, since the medicine storage cassette 1 can be conveyed at high speed, the medicine dispensing time can be shortened. Also. Since the winding spring 232d is provided, the PTP sheet 100 can be pressed against the PTP sheets 100 having different heights.

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 the PTP sheet 100 has flat edges (sheet portions) at both ends, but one edge is wider than the other edge. The wide edge 100a is generally called an ear. In the medicine dispensing device having a function of cutting a fraction of the packaged medicine from the medicine sheet, if the orientation of the pocket of the PTP sheet 100 taken out from the medicine accommodating cassette 1 or the orientation of the wide edge 100a is indefinite, a fraction of the medicine packaged. May not be cut out properly. With respect to the PTP sheet 100 that is not the target of 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 the normal to the sheet surface of the PTP sheet 100, the minor axis, and the major axis. The short axis and the long axis are orthogonal to each other in the plane of the PTP sheet 100. An example of the position of the center of rotation about the major axis is the axis passing through the center of the PTP sheet 100 in the short side direction. An example of the position of the center of rotation about the minor axis is the axis passing through the center of the PTP sheet 100 in the longitudinal direction. An example of the center of rotation about the normal is the intersection of the center of rotation about the major axis and the center of rotation about the minor axis. Here, the PTP sheet 100 is line-symmetric with respect to the second axis (long axis). If the center of rotation about the normal is provided near the intersection of the center of rotation about the major axis and the center of rotation about the minor axis, the space required for rotation about the normal can be reduced. . In this embodiment, the rotation around the normal line is adopted.

  FIG. 27 is an explanatory diagram showing changes in the state 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 (the 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 there is 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 dispensed leading PTP sheet 100, the state changes due to rotation around the major axis, the state change due to rotation around the minor axis, and the state due to rotation around the normal line. It is possible to align with any one of the states by causing two state changes among the changes. That is, the pocket of the PTP sheet 100 and the wide edge 100a can be oriented in the same direction. Alternatively, the wide edge 100a may be oriented in only one direction.

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

  Further, the dispensing operation section 110 is configured to operate by the suction operation section 6 for sucking and pulling out the leading PTP sheet 100 in the medicine accommodating cassette 1, and the suction operation section 6 when a fraction of the packaged medicine is required. A sheet gripping portion 8 for gripping and receiving the pulled-out PTP sheet 100, the PTP sheet 100 pulled out by the suction operation portion 6 when a fraction of the packaging medicine is required, with the normal to the sheet surface as an axis. A normal rotation unit 13 for rotating is provided. The normal line of the sheet surface is the normal line at the center position of the sheet surface of the PTP sheet 100. Here, the normal line at the central position of the seat surface is parallel to the perpendicular line (orthogonal line) of the seat surface when it is assumed that the PTP sheet 100 is not a curved surface but a flat surface. Further, in this embodiment, the direction of the normal to the sheet surface is equal to the front-rear direction, the direction in which the PTP sheets 100 are arranged in the medicine storage cassette 1, and the movement direction of the medicine storage cassette 1. Further, when the PTP sheet 100 is dispensed, the normal rotation unit 13 is positioned at the central position of the dispensing unit 120 of the medicine container cassette 1 (the central position of the PTP sheet 100).

  The sheet gripping portion 8 includes a gripping body portion 81 that is rotatably provided around a horizontal axis, a rotating portion 82 that rotates the gripping body portion 81, and a left-right moving device 83 that moves the rotating portion 82 in the left-right direction. With. Further, the sheet grip portion 8 also functions as a detection portion for the wide edge 100a.

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

  The suction body 61 is connected to the base 611 via a guide rail 65e of the front-rear moving device 65. The suction main body 61 is moved in the front-rear direction (the direction in which the suction main body 61 approaches and separates from the dispensing portion 120 of the medicine storage cassette 1) by the front-rear moving device 65. The front-rear moving device 65 includes a moving nut 65a fixed to the back surface of the suction body 61, a feed screw 65b screwed to the moving nut 65a, a motor 65c for rotating the feed screw 65b, and And a belt transmission mechanism 65d for transmitting the driving force of the motor 65c to the feed screw 65b.

  The forward / backward moving device 65 is faster than the moving operation unit 130 in the medicine storage cassette 1 moving the PTP sheet 100, and the moving operation unit 130 moves the PTP sheet 100 in the leading PTP direction. The sheet 100 can be sucked to move the suction body 61.

  Further, when the suction main body 61 is moved in the direction of approaching the medicine containing cassette 1 by the front-rear moving device 65, the suction main body 61 comes into contact with and adsorbs on the sheet portion of the leading PTP sheet 100. When the pocket portion of the leading PTP sheet 100 faces the payout operating portion 110 side, the movable plate 62a of the pocket detection portion 62 is displaced according to the convex height of the pocket portion. The positional 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 that are horizontally arranged. As shown in FIGS. 37 (A), 37 (B) and 37 (C), the four suckers 61a arranged side by side have a first group consisting of two on the side close to the sheet grip portion 8 and It is divided into a second group consisting of two pieces on the side far from the sheet grip portion 8. The suction for each group can be performed by operating an electromagnetic valve provided on the intake passage 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 suction off, a strong suction force is generated in the two suction cups 61a of the first group, and the PTP sheet 100 is The two suckers 61a of one group are sucked with high reliability. When the suction operation is also performed on the four suction cups 61a of the second group after the suction operation of the first group is performed, the PTP sheet 100 can be accurately suction-held by the four suction cups 61a. . As described above, by driving a part of a plurality of suction cups (a part on the side close to the sheet grip portion 8) in advance, the PTP sheet 100 can be accurately suction-held.

  The normal rotation section 13 includes a suction rotation pipe section 13a at the center of the four suction cups 61a. A suction cup portion 13b is provided at the tip of the suction rotary pipe portion 13a. The rear side of the suction rotary pipe section 13a is supported by the bearing section 13c. 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 a 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 dispensing position by the delivery section moving section 4, the medicine 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 performed by the lid opening / closing unit 160. Next, the suction main body 61 moves in a direction approaching the medicine storage cassette 1 to bring the suction cup 61a into contact with the PTP sheet 100 in the medicine storage cassette 1 to suck the PTP sheet 100. At this time, the direction 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. The leading PTP sheet 100 is pulled out from the medicine storage cassette 1 by moving the suction main body 61 in the direction away from the dispensing unit 120.

  When suction is performed by the suction main body 61 after all the PTP sheets 100 have been pulled out from the medicine storage cassette 1, the suction cup 61a sucks the pressing member 131 of the moving operation unit 130. Become. Since a plurality of groove portions 131a are formed on the pressing surface of the pressing member 131 in contact with the PTP sheet 100 as shown in FIG. 5, when the PTP sheet 100 becomes empty, the suction cup 61a is pressed by the pressing member 61a. It contacts 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 lapse of a certain time. The control unit 1005 can determine that the PTP sheet 100 may be out of stock when the suction by the suction main body unit 61 cannot be completed even after a lapse of a certain time. When the suction main body 61 is provided with four suction cups 61a, the number of the groove portions 131a is, for example, four. That is, the groove portions 131a may be provided at least at the positions corresponding to the suction cups 61a as many as the suction cups 61a. When all the suction cups 61a come into contact with the pressing surface of the pressing member 131, only the suction circuits of some of the suction cups 61a are in a predetermined negative pressure state, and the suction circuits of the other suction cups 61a have a predetermined negative pressure. The medicine storage cassette 1 may be configured so as not to be in a state. As an example of this configuration, there is a configuration in which the number of grooves 131a is smaller than the number of suction cups 61a. With such a configuration, when the PTP sheet 100 is empty, only some of the suction circuits of the suction cups 61a are in the negative pressure state, and the PTP sheet 100 is in the negative pressure state based on the number of suction circuits. Even if the sheet 100 is in the medicine storage cassette 1, it is possible to determine that the suction failure of the suction circuits of all the suction cups 61a does not become negative pressure due to some problem and that the PTP sheet 100 has become empty. .

  In the case where a fraction of the packaged medicine is required, if it is determined by the detection result of 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 the PTP sheet. The sheet 100 is passed to the sheet grip section 8. The sheet gripping portion 8 has a pocket portion facing the medicine storage cassette 1 side. Then, the suction main body 61 receives the PTP sheet 100 from the sheet gripper 8.

  When the PTP sheet 100 is gripped, the sheet gripping portion 8 determines whether the gripped side is the wide edge 100a of the PTP sheet 100. If the sheet gripping portion 8 grips the wide edge 100a, the normal rotation by the normal rotation unit 13 is not performed, and the suction main body 61 approaches the medicine accommodating cassette 1. And moves the PTP sheet 100 onto the sheet storage unit 141 of the lid 140. The wide edge 100a of the PTP sheet 100 dropped on the sheet storage section 141 faces the sheet gripping section 14 described later, and the side opposite to the wide edge 100a is a cutter section provided in the dispensing operation section 110. I will turn to the 15 side. Even when the pocket portion of the PTP sheet 100 faces the medicine storage cassette 1 side, the suction main body portion 61 passes the PTP sheet 100 to the sheet grip portion 8 for detecting the wide edge 100a. However, in this case, the PTP sheet 100 is not rotated by the sheet grip 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 61 passes the PTP sheet 100 to the normal rotation unit 13. The normal rotation unit 13 rotates the PTP sheet 100 around the normal line so that 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 medicine storage cassette 1 face each other with their pocket forming sides facing each other, the lower end of the two PTP sheets 100 While the upper end position of the PTP sheet 100 that is in contact with the storage bottom in the medicine storage cassette 1 is the original position, the upper end position of the other PTP sheet 100 is higher than the original position by a height H. The height H is different for each medicine, and the information on the height H is recorded in the master table for each medicine. When the PTP sheet 100 has three rows of pockets, the suction height from the lower end of the sheet is about 1/3 of the height of the PTP sheet 100 as shown in FIG. When the number of pockets is even, such as two or four, the suction height is about ½ of the height of the PTP sheet 100. The suction height differs for each medicine and is recorded in the master table. The information on the height H and the information on the suction height can be used when the PTP sheet 100 is dispensed by the suction main body 61.

  When the PTP sheet 100 does not face the pocket portion toward the suction main body portion 61, the first suction trial is performed regardless of whether the PTP sheet 100 is in contact with the storage bottom portion in the medicine storage cassette 1. Then, the suction is almost certainly successful, and the PTP sheet 100 can be taken out from the medicine storage cassette 1. However, when the PTP sheet 100 is not in contact with the storage bottom of the medicine 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 normal rotation unit 13 rotates the PTP sheet 100 around the normal so that the wide edge 100a faces 180 degrees in the opposite direction, the PTP sheet 100 is rotated. When it is 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 the suction is performed at the original suction height.

  In this way, when the suction position is not the original position, when the suction main body 61 performs the moving operation for dropping the PTP sheet 100 onto the sheet storage unit 141, the lower end of the PTP sheet 100 is moved. There is a risk of contact with the upper end 143 of the wall of the entrance of the sheet storage unit 141 shown in FIG. Therefore, in the 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 is performed by 180 degrees, the medicine sheet generated by 180 degrees rotation is The process of eliminating (absorbing) the fluctuation of the lower edge position is performed.

  The process of eliminating the fluctuation may be an operation of moving the suction main body 61 upward by a fixed distance or a non-fixed 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 of the entrance of the sheet storage unit 141.

  When the above-mentioned fixed distance is adopted, the PTP sheet 100 of any medicine is moved upward by the above-mentioned fixed distance. On the other hand, the non-constant distance is, for example, the height H or a distance in which the height H is taken into consideration, and in this case, the PTP sheet 100 is moved upward by a different distance for each medicine. Both the movement of the fixed distance and the movement of the non-fixed distance are movement operations of the suction main body 61 that absorbs the positional deviation of the PTP sheet 100 in the medicine containing cassette 1. As described above, the positional deviation of the PTP sheet 100 in the medicine storage cassette 1 is caused when the two front and rear PTP sheets 100 in the medicine storage cassette 1 face each other on the pocket forming side. Occurs in

  When the PTP sheet 100 that is not in contact with the storage bottom portion in the medicine storage cassette 1 is located at the top and the pocket portion thereof faces the suction main body portion 61 side, the first suction trial may fail. For example, the suction cannot be completed when the suction cup 61a hits the pocket portion to form a gap. If the suction cannot be completed even after a certain period of time or longer, it is determined as a failure. In this case, for example, the movable plate 62a of the pocket detector 62 is moved forward and then moved downward by a fixed distance or a non-fixed distance. By this movement, the other PTP sheet 100 can be brought into contact with the storage bottom portion in the medicine storage cassette 1 by the movable plate 62a, and the PTP sheet 100 can be sucked with almost no failure in the next suction trial. And can be taken out from the medicine storage cassette 1. The second try may be performed after the first failure, and when it is determined that this also fails, the movable plate 62a or the like may be moved downward by a fixed distance or a non-fixed distance.

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

  Further, as shown in FIG. 8, when the two front and rear PTP sheets 100 in the medicine storage cassette 1 face each other on the formation sides of the pocket portions, the lateral edges of these two PTP sheets 100 are It may happen that they do not match.

  Here, as described above, when the PTP sheet 100 is gripped, the sheet grip portion 8 determines whether the gripping side is the wide edge 100a of the PTP sheet 100. The sheet gripper 8 is movable in the lateral direction, and is provided with an optical sensor 801, for example, 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 grip 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 laterally displaced due to the lateral edges of the two PTP sheets 100 not matching, the sheet gripping portion 8 is detected by the detection of the lateral edges. The PTP sheet 100 can be properly gripped.

  On the other hand, when the suction main body 61 executes the moving operation for dropping the PTP sheet 100 onto the sheet storage unit 141 in the state where the lateral shift exists, the PTP sheet 100 is changed to the state shown in FIG. There is a possibility that the sheet storage unit 141 shown may fail to be stored. Therefore, when the sheet gripping section 8 receives the PTP sheet 100 from the suction main body section 61 and then transfers the PTP sheet 100 to the suction main body section 61 again, the sheet gripping section 8 shifts in the lateral direction. Move laterally to eliminate the.

  Specifically, in the master table, a distance d from the sheet center of the PTP sheet 100 to the lateral edge of the sheet for each medicine (for example, information such as the number of motor pulses required for the sheet gripping portion 8 to move). It can be indicated by.) Is recorded. Further, for example, a stepping motor is used for the lateral movement, and it is possible to judge how far the sheet gripping portion 8 has moved from the reference position. Further, the distance D from the reference position to the center of the dispensing unit 120 of the medicine storage cassette 1 (the axial position of the normal rotation unit 13) is known. Therefore, when the optical sensor 801 cannot detect the lateral edge of the sheet at the position where the sheet grip portion 8 has moved by the distance obtained by subtracting the distance d from the distance D, a positional deviation occurs in the lateral direction. You can determine that Therefore, when the sheet gripping section 8 receives the PTP sheet 100 from the suction main body section 61 and then transfers the PTP sheet 100 to the suction main body section 61 again, the sheet gripping section 8 shifts in the lateral direction. The amount is moved horizontally to adjust. This eliminates the lateral displacement. It should be noted that, after the sheet grip portion 8 receives the PTP sheet 100 from the suction main body portion 61, the sheet grip portion 8 may temporarily return to the reference position and move laterally by a distance obtained by subtracting the distance d from the distance D. .

  The sheet grip portion 14 is provided so as to be movable in the left-right direction of the medicine dispensing device 101. The sheet gripping unit 14 grips the wide edge 100a of the PTP sheet 100 dropped on the sheet storage unit 141 and moves the PTP sheet 100 to the cutter unit 15 side. The cutter portion 15 includes a fixed blade 15a and a movable blade 15b, and can cut the PTP sheet 100 into an L shape. After the cutting, the sheet gripping unit 14 moves the PTP sheet 100 to the sheet storage unit 141 side and places the PTP sheet 100 on the sheet storage unit 141. In addition, the fractional packing medicine obtained by the above cutting falls on the belt conveyor 15c. The fraction of the packaged medicine is conveyed by the belt conveyor 15c, passes through the notch portion 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 causes the suction main body 61 to remove the PTP sheets from the medicine accommodating cassette 1 in parallel with the operation of cutting out a fraction of the packaged medicine. The operation of taking out 100 is repeated, and the taken out PTP sheet 100 is sequentially dropped into the sheet stocker 112. As described above, if the operation of taking out the PTP sheet 100 from the medicine storage cassette 1 is performed in parallel with the process of cutting out the fractional packed medicine, the time required for the dispensing can be shortened.

  For example, the operation of setting the fraction cut-out PTP sheet 100 in the sheet storage unit 141 is performed on the PTP sheet 100 first taken out from the medicine storage cassette 1. Then, a first process of cutting out a fraction of the packaged medicine from the PTP sheet 100 set in the sheet storage unit 141, and a second process of extracting a necessary number of PTP sheets 100 from the medicine accommodating cassette 1 by the suction main body 61. In parallel. In addition, even when the PTP sheets 100 taken out after the second but not the first are set in the sheet storage unit 141, the first process and the second process can be performed in parallel. In addition, if the PTP sheet 100 for fractional cutout or some fractional packaging medicines has already remained in the sheet storage unit 141, and if fractional cut is performed using this, the second process should be executed during that period. If 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 performed.

  Further, when the prescription data requires a process of paying out a plurality of PTP sheets 100, and a PTP sheet 100 for fraction cutting is also required, the following process may be performed. For example, the direction of the wide edge 100a of the PTP sheet 100 that is first taken out from the medicine storage cassette 1 is detected by the sheet grip portion 8. When the wide edge 100a does not face the predetermined direction, the first PTP sheet 100 is dropped and paid out. Similar processing is performed on the subsequent PTP sheet 100.

  Here, for example, when it is necessary to dispense three PTP sheets 100 and a fraction of the packaged medicine, if the wide edge 100a of the third PTP sheet 100 is in the predetermined orientation, The third PTP sheet 100 taken out is set in the sheet storage unit 141. That is, the PTP sheet 100 taken out as the third sheet is used as the PTP sheet 100 for fraction cutting. Since the number of PTP sheets 100 to be dispensed is three, the PTP sheets 100 are subsequently taken out from the medicine storage cassette 1 and dispensed.

  On the other hand, when the wide edge 100a of the third PTP sheet 100 taken out is not oriented in a predetermined direction, the third PTP sheet 100 taken out is dropped and paid out. Then, the fourth PTP sheet 100 is taken out from the medicine 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 fraction storage sheet storage unit 141 provided in the medicine storage cassette 1, a plurality of PTPs taken out from the medicine storage cassette 1 are required. The PTP sheet 100 facing the predetermined direction among the sheets 100 is stored 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 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 minimized, so that the time for the medicine dispensing process can be shortened. In this case, there is a possibility that the mechanical detection operation by the sheet gripping portion 8 for detecting the direction of the wide edge 100a of the PTP sheet 100 will increase. Here, if the configuration is such that the orientation of the wide edge 100a of the PTP sheet 100 taken out from the medicine storage cassette 1 is detected by the image sensor, the mechanical detection operation is not necessary, and it is paid out by improving the image processing speed. You can save time.

  In the above method, among the plurality of PTP sheets 100 taken out from the medicine storage cassette 1, the PTP sheet 100 in which the direction of the wide edge 100a and the direction of the pocket portion are both predetermined directions is set in the sheet storage unit 141. It may be housed in. When one or both of the orientations of the wide edges 100a and the pocket portions of all the taken out PTP sheets 100 are not oriented in a predetermined orientation, the normal rotation portion 13 which is a rotation operation portion and And / or the last PTP sheet 100 is rotated by the sheet grip portion 8. The image sensor can also detect the pocket portion of the PTP sheet 100 taken out from the medicine storage cassette 1.

  In the above-described embodiment, the pockets and the 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 sheets in the drug storage cassette with the pockets aligned. In this case, it is possible to omit the means for detecting the pocket and the means for inverting the pocket direction.

  Further, if at least the wide edges of the medicine sheet taken out from the medicine accommodating cassette can be oriented in the same direction, it is possible to perform fraction cutting on the medicine sheet even if the pocket orientations are not the same.

  Here, an operation example for paying out the PTP sheets 100 one by one will be described. In this operation example, the leading PTP sheet 100 in the housing portion 11 is sucked by the suction main body portion 61, and the PTP sheet 100 is pushed in a direction opposite to the moving direction of the PTP sheet 100 by the moving operation portion 130. Then, the PTP sheet 100 is pulled in the same direction as the moving direction at a speed higher than the moving speed of the PTP sheet 100 by the moving operation unit 130. Thereby, the contact member 121a of the first restriction portion 121 is positioned between the leading PTP sheet 100 and the second PTP sheet 100, and only the leading PTP sheet 100 is paid out.

  The forward / backward movement device 65 moves the suction operation unit (take-out unit) 6 in a direction opposite to the direction in which the movement operation unit 130 moves the PTP sheet 100, and then (by pushing in the opposite direction). , The moving operation unit 130 moves in the opposite direction.), In a direction in which the moving operation unit 130 moves the PTP sheet 100 faster than the moving operation unit 130 moves the PTP sheet 100. It is desirable to move the suction operation unit 6 that holds the PTP sheet 100 at the top. 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 top PTP sheet 100 and the first PTP sheet 100 when the PTP sheet 100 is paid out. The distance from the 1-limitation unit 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 portion 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 restriction unit 121. At this time, the distance between the first PTP sheet 100 and the second PTP sheet 100 can be increased, and the first restriction portion 121 can easily enter between the first PTP sheet 100 and the second PTP sheet 100. Become.

  The suction main body portion 61 sucks the leading PTP sheet 100 in the housing portion 11 and pushes the PTP sheet 100 in a direction opposite to the moving direction of the PTP sheet 100 by the moving operation unit 130. Suction of the PTP sheet 100 by the suction main body 61 is reliably performed.

[Tray moving section 500]
The tray moving unit 500 does not have to exist in the type in which the single medicine dispensing device 101 constitutes the medicine dispensing device. 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 drug tray T in the left-right direction of the drug dispensing device 101. As shown in FIGS. 32 (A) and 32 (B), the conveyor section 51 is provided with two moving belts 51b on both sides of the monorail section 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 of the medicine tray T engages with the monorail portion 51a. The moving belt 51b is driven by a motor 51c. Since the medicine tray T has a structure guided by the monorail portion 51a, the structure can be simplified. The recess C is formed by utilizing the fact that the accommodation recesses T1, T2, T3, and T4 are formed, but the invention is not limited to this. For example, as shown in FIG. 4 (B), it is also possible to use a medicine tray T in which one accommodation recess T11 is formed. The medicine tray T has two leg portions T10 on the lower surface of the tray body, and a recess C into which the monorail portion 51a is inserted is formed between the leg portions T10. Even when the medicine tray T does not have a plurality of accommodation recesses, it is possible to arrange the medicine at appropriate positions in the front, rear, left, and right of the medicine tray T by moving the medicine tray T forward, backward, left, and right by the conveyor unit 51. .

  Further, the conveyor section 51 is moved in the front-rear direction of the medicine dispensing apparatus 101 by the front-rear drive section 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 section 51, and the feed screw 52a is screwed onto the moving nut. When the feed screw 52a is rotated by the motor 52b, the conveyor unit 51 is moved in the front-back direction. Further, the conveyor section 51 is guided in the front-rear direction by the guide shaft 52c.

  The conveyor section 51 is provided with a positioning section 53. The positioning unit 53 uses a driving force of one motor 53a to rotate a shaft (support shaft) 53b provided in the left and right direction of the medicine dispensing device 101, so that the medicine tray is provided at a plurality of positions. T can be positioned. The positioning portion 53 includes six stopper members 531 that are 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 rotatably provided with a rotating portion 531b. The rotating portion 531b can rotate when coming into contact with the side surface of the medicine tray T that moves in the left-right direction of the medicine dispensing device 101. A shaft insertion hole 531c is formed in the 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.

  A 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 fixed portion 531e, and the other end is engaged with the main body portion 531a, so that the stopper member 531 rotates together with the shaft 53b. Move. When the stopper member 531 is tilted in the traveling direction of the medicine tray T by this rotation of the body, the movement of the medicine tray T is blocked and positioning is performed. On the other hand, when the rotation 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 block the movement of the medicine tray T.

  That is, the positioning portion 53 stands up by the rotation of the shaft 53b in the first rotation direction to allow passage of the medicine tray T, while tilting by the rotation of the shaft 53b in the second rotation direction. And a plurality of stopper members 531 that prevent the medicine tray T from passing through, and the stopper member 531 that does not tilt when the shaft 53b rotates in the second rotation direction and that contacts the side surface portion of the medicine tray T. And a winding spring 531d (elastic member) that allows

  For example, when the drug tray T is detected by a sensor (not shown) before the target positioning position, the motor 53a is operated to rotate the shaft 53b, so that the drug tray T is positioned at the target positioning position. You can stop with. In this way, the plurality of stopper members 531 work together to position the medicine tray T, while a part of the plurality of stopper members 531 does not work together and does not function as a stopper. This structure is realized by one motor 53a and one shaft 53b, which simplifies the structure.

  The tray moving section 5 includes the conveyor section 51 and a fixed conveyor section 55. That is, the tray moving unit 5 corresponds to a structure in which the tray moving unit 500 includes a fixed conveyor unit 55 on the front side of the conveyor unit 51 (the front side of the medicine dispensing apparatus 101) (see FIG. 1). ). The positioning section 53 is not provided on the conveyor section 55. The conveyor unit 55 can execute a process of receiving an empty drug tray T from the tray stocker 1012 and passing the empty drug tray T to the conveyor unit 51 of the tray moving unit 500. The tray moving unit 500 that has received the empty medicine tray T moves the conveyor unit 51 rearward and transfers the empty medicine tray T to the conveyor unit 51 of the tray moving unit 5. By providing the tray moving unit 500, it is possible to operate a plurality of drug trays T such that a drug tray to be used for the next dispensing is kept on standby on the tray moving unit 500.

  The tray moving unit 5 is provided below the dispensing operation unit 110 so as to be movable in the front-rear direction of the medicine dispensing device 101, and 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 position of the stopper member 531 in the conveyor unit 51 of the tray moving unit 5, the positions of the sheet stockers 112 of the first payout operation unit 110 and the second payout operation unit 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 accommodation recesses T1, T2, T3, T4 of the medicine tray T are aligned with the position are shown. In this stop position example, in order to make the medicine dispensing device compact, the distance between the positions where the medicine tray T is desired to be stopped (arrangement interval of the stopper members 531) is made shorter than the tray size of the medicine tray T in the transport direction. It is illustrated. In order to realize this exemplary configuration, the positioning portion 53 ensures that the shaft 53b is rotated even when the stopper member 531 located on the side surface of the medicine tray T contacts the side surface of the tray. The stopper member 531 is made to function 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. If the conveyor section 51 is moved to the rear side of the medicine dispensing device, the fixed stopper section 532 does not become an obstacle and the medicine tray is placed between the tray moving section 500 and the tray moving section 5. T can move.

  In addition, as a case where the PTP sheet 100 cannot be pulled out by the suction operation unit 6, there are cases where the inside of the medicine storage cassette 1 is empty (stockout) and cases where suction failure occurs. In this embodiment, a weighing scale for measuring the weight of the medicine storage cassette 1 is provided, for example, in each dispensing operation unit 110, and when the medicine storage cassette 1 is gripped, the number of PTP sheets 100 stored ( Inventory) can be determined. Therefore, when the PTP sheet 100 cannot be pulled out by the suction operation unit 6 in the dispensing of the PTP sheet 100 from the medicine storage cassette 1 that is determined to be in stock, the following processing can be performed. That is, if it is determined that the product is in stock and suction is not possible, it is determined that suction failure has occurred and error processing is performed. Perform error handling. This allows the user to be informed of the exact state of the device 101. In the case where the product is set to continue the payout process without causing an error when the product is out of stock, if the product is not out of stock, it is possible to appropriately perform processing such as stopping the apparatus by error processing.

  It may be possible to prohibit setting of two front and rear PTP sheets 100 in the medicine storage cassette 1 with the formation sides of the pocket portions facing each other for a specific medicine. For example, it is assumed that a drug that causes suction failure because the two PTP sheets 100 are strongly bonded to each other is prohibited. Such prohibition information can be registered in the master table for each drug. When the medicine storage cassette 1 in which the medicine for which prohibition information is set is stored is selected as the medicine replenishment target, as shown in FIG. 38, the control unit 1005 causes the display 1002 to set the PTP sheet 100. A message that calls attention can be displayed. For example, "It is prohibited to set this drug sheet in the cassette so that the pocket sides face each other. When setting the drug sheet in the cassette, be sure to orient the drug sheet in a certain direction." Display a message. The drug storage cassette is selected by reading the drug storage cassette ID from a barcode printed on the drug storage cassette or an information recording unit (for example, RFID tag: radio frequency identifier tag) held in the drug storage cassette. . Not only when the medicine storage cassette 1 is selected as a medicine replenishing target, but when a specific medicine 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, when this error occurs in the medicine container 1 of the specific medicine, the PTP sheet is displayed on the display 1002 together with the error display. A message that calls 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 pocket sides face each other. Please check that the orientation of the medicine sheet is constant."

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

  In the above-described embodiment, the suction operation unit 6 is shown as the take-out unit that holds the PTP sheet 100, but the present invention is not limited to such suction, and the first PTP sheet 100 in the medicine storage cassette 1 is bonded or grasped. It is also possible to pay it out.

  In the medicine dispensing apparatus 101 of the above-described embodiment, the delivery section 3 is moved by the delivery section moving section 4, but as shown in FIG. 35, the delivery section 3 is fixedly arranged and the delivery operation section 110 is arranged. May be movably provided within the arrangement range of the plurality of delivery units 3 in charge. That is, the payout operation unit 110 may move between the plurality of delivery units 3. Further, as shown in FIG. 36, a plurality of the delivery sections 3 and the payout operation sections 110 may be fixedly arranged in a one-to-one correspondence.

  Further, in the medicine dispensing device 101 of the above embodiment, it is detected whether the wide edge 100a of the PTP sheet 100 faces left or right, but the invention is not limited to this. It is also possible to set the PTP sheet 100 in the medicine accommodating cassette 1 so that its major axis is vertical. In this case, it is possible to detect whether the wide edge 100a of the PTP sheet 100 is facing up or down. You may

  Further, in the medicine dispensing device 101 of the above-described embodiment, the medicine storage cassette 1 is moved horizontally in the cassette shelf, but the medicine storage cassette 1 is moved vertically to be stored in the cassette shelf. Is also possible. The medicine storage cassette 1 may be one in which the PTP sheets 100 are vertically stacked and stored. In this case, the suction pad of the suction main body 61 in the dispensing operation unit 110 is provided downward, and the uppermost PTP sheet 100 is taken out from the medicine storage cassette 1.
