The contact plate 38a is installed at a position where the end portion arrives at a position slightly distant from the locus J in the radial direction of the drum 31. Therefore, when the cassette 32 is not firmly attached to the drum 31 and protrudes outward in the radial direction of the drum 31, the cassette 32 comes into contact with the contact plate 38a as the drum 31 rotates. , The contact plate 38a swings around the hinge 38c. As a result, the contact plate 38a hits the switch 38b and is turned on, and a defective mounting of the cassette 32 is detected.

As shown in FIGS. 2 and 3, a drug standby mechanism 50 is provided below the drum 31 described above. As shown in FIGS. 3 and 7, the drug standby mechanism 50 is composed of a funnel-shaped standby hopper 51, a movable lid 52, and a lid operation mechanism 53. The standby hopper 51 is attached to the main body box 54 of the drug standby mechanism 50, and the movable lid 52 is attached to the lid operating mechanism 53 attached to the standby hopper 51.

More specifically, as shown in FIG. 7, the standby hopper 51 has a mechanism arranging portion 55 for arranging the lid operating mechanism 53 in the central portion, and a plurality of discharge ports 5 are located at positions surrounding the mechanism arranging portion 55.
6 is provided. Further, a flange 57 is provided on the outer edge portion of the standby hopper 51. The standby hopper 51 is fixed to the main body box 54 by screwing a flange 57 or the like.

The lid operation mechanism 53 is provided to move the movable lid 52 up and down with respect to the standby hopper 51. The lid operating mechanism 53 includes a motor 58 as a power source, a mechanism unit 60 that operates by the power received from the motor 58, and a power transmission shaft 61 for transmitting the power of the motor 58 to the mechanism unit 60. The motor 58 is attached so that the rotation shaft 58a is substantially perpendicular to the side surface of the main body box 54 and projects toward the inside of the main body box 54.

As shown in FIG. 8, the mechanism unit 60 is roughly classified into a drive unit 60a that operates by receiving power from the motor 58 and a driven unit 60b that operates by receiving power from the drive unit 60a. The drive unit 60a has a bevel gear 60c attached to the tip of the power transmission shaft 61, and a bevel gear 60d provided so as to mesh with the bevel gear 60c. The bevel gear 60d is attached to one end side of a rotating shaft 60e erected so as to face substantially perpendicular to the power transmission shaft 61. Further, a drive gear 60f is provided on the other end side of the rotary shaft 60e so that the drive gear 60f can rotate integrally with the bevel gear 60d. Therefore, when the rotational power is transmitted from the motor 58 side via the power transmission shaft 61, the drive gear 60f rotates about the rotation shaft 60e.

On the other hand, the driven portion 60b includes a rotary cylinder member 60 g, a driven gear 60h, a cam 60i, and a slide shaft 60j.

The driven gear 60h is an annular gear having an outer diameter substantially the same as that of the rotary cylinder member 60g. The driven gear 60h is fixed to the upper end of the rotary cylinder member 60g. Further, the driven gear 60h meshes with the driving gear 60f provided in the driving unit 60a. Therefore, when the drive gear 60f rotates under the power of the motor 58, the power is transmitted to the drive gear 60f, and the rotary cylinder member 60g rotates about the axis.

The cam 60i is a so-called end face cam, and has a shape such that a portion on the end face 60k side cuts a cylinder with a plane P intersecting the bus. More specifically, assuming a plane P passing through the end face 60k as shown in FIG. 8B, the end face 60k is the most, based on the state where the cam 60i is arranged so that the end face 60k side is upward. It has an upper end portion 60s located on the upper side and a lower end portion 60t located on the lowermost side, and has a shape in which the two are gently connected by an intermediate portion 60u.

The cam 60i is arranged with the end face 60k side facing upward and inside the rotary cylinder member 60g. The cam 60i is integrated with the rotary cylinder member 60g, and can rotate in conjunction with the rotary cylinder member 60g. The slide shaft 60j is a shaft body connected to the movable lid 52, and is divided into a small diameter portion 60p and a large diameter portion 60q with a flange portion 60m provided on one end side in the length direction as a boundary. The small diameter portion 60p is located at a position on the end side of the slide shaft 60j with respect to the flange portion 60m, and has a smaller outer diameter than the other portions.

The large diameter portion 60q is a portion forming a main portion of the slide shaft 60j. The slide shaft 60j can be freely slid in the axial direction, that is, in the vertical direction with respect to the cam 60i by inserting the large diameter portion 60q inside the cam 60i. A roller 60r is rotatably attached to the peripheral surface of the large diameter portion 60q and at the intermediate portion in the length direction of the large diameter portion 60q. The roller 60r comes into contact with the end face 60k of the cam 60i in a state where the slide shaft 60j is inserted inside the cam 60i with the large diameter portion 60q side at the head. Therefore, when the cam 60i rotates about the axis, the roller 60r rolls on the end face 60k, and the slide shaft 60j moves up and down according to the undulations of the end face 60k.

The slide shaft 60j is integrated with the movable lid 52 by inserting the small diameter portion 60p into the recess 66 provided at the substantially center of the movable lid 52 and screwing the flange portion 60m to the movable lid 52. More specifically, the movable lid 52 is a disk-shaped member having a substantially circular top surface of the lid 52a and a peripheral surface 52b of the lid surrounding the outer periphery thereof. A recess 66 is provided inside the movable lid 52 and at a substantially central portion of the top surface 52a of the lid. The movable lid 52 is integrated with the slide shaft 60j by inserting the small diameter portion 60p of the slide shaft 60j described above into the recess 66 and attaching a screw over the lid top surface 52a and the flange portion 60m.

The movable lid 52 moves up and down with the operation of the lid body operating mechanism 53 described above, and opens and closes each discharge port 56 provided in the standby hopper 51. More specifically, in the lid operating mechanism 53, when the rotary cylinder member 60g rotates with the operation of the motor 58, the cam 60i rotates relative to the slide shaft 60j about the axis. Along with this, the roller 60r attached to the slide shaft 60j turns along the end face 60k of the cam 60i, and moves up and down according to the undulations of the end face 60k. As a result, the slide shaft 60j and the movable lid 52 integrated with the slide shaft 60j slide in the vertical direction with respect to the cam 60i.

More specifically, as shown in FIG. 9A, when the roller 60r provided on the large diameter portion 60q of the slide shaft 60j is in contact with the position corresponding to the lower end portion 60t of the cam 60i, the slide The shaft 60j is in the position of being retracted to the lowermost position in the cam 60i. In this case, the movable lid 52 is in a state where the lid connecting cylinder 62 of the mechanism unit 60 is lowered as shown in FIG. 10A, and the lower end portion of the lid peripheral surface 52b is on the inner peripheral surface of the standby hopper 51. It will be in contact. In this state, each discharge port 56 provided in the standby hopper 51 is surrounded by the peripheral surface 52b of the lid and dammed up, so that the medicine charged in the standby hopper 51 can be stored.

On the other hand, when the motor 58 provided in the lid operating mechanism 53 operates, the rotary cylinder member 60 g and the cam 60i integrated therein start to rotate as shown by the arrows in FIG. Along with this, as shown in FIG. 9B, the intermediate portion 60u of the end face 60k arrives at a position corresponding to the roller 60r. Here, as described above, the slide shaft 60j can freely slide in the vertical direction with respect to the cam 60i. Therefore, when the intermediate portion 60u approaches the position corresponding to the roller 60r as the cam 60i rotates, the slide shaft 60j is pushed upward. Along with this, the movable lid 52 integrally attached to the slide shaft 60j is also gradually pushed upward, and as shown in FIG. 10B, the lower end of the lid peripheral surface 52b and the standby hopper 51 There is a gap between it and the inner peripheral surface of the.

After that, when the cam 60i continues to rotate, the intermediate portion 60u that has reached the position corresponding to the roller 60r passes through as shown in FIGS. 9C and 9D, and the height of the end face 60k gradually increases. As it gets higher, the movable lid 52 is pushed up further. Along with this, the gap between the lower end of the movable lid 52 integrally attached to the slide shaft 60j and the inner peripheral surface of the standby hopper 51 is further expanded. Then, when the cam 60i rotates until the upper end portion 60s of the end surface 60k arrives at a position corresponding to the roller 60r, the gap between the peripheral surface of the lid 52b and the inner peripheral surface of the standby hopper 51 becomes maximally open. , The state in which the drug can sufficiently pass, that is, the state in which each discharge port 56 is opened.

Subsequently, the operation of the drug dispensing system 1 of the present embodiment will be described in detail. In the drug dispensing system 1, the main unit 2 and the subunit 3 cooperate with each other to wrap each package of the drug according to the prescription in the packaging paper 98 and dispense the drug. Specifically, the drug dispensing system 1 prescribes a drug in the main storage unit 20 and the hand-handling unit 23 provided on the main unit 2 side, and a drug in the sub storage unit 120 provided on the subunit 3 side. One packet at a time is dispensed to the drug preparation section 80 on the main unit 2 side, and this is packaged in the drug packaging section 21 and dispensed.

More specifically, when a drug is prescribed by the drug dispensing system 1, if the drug to be dispensed is in the main storage unit 20 on the main unit 2 side, the motor 43 of the cassette 32 accommodating the corresponding drug. Works. Along with this, the drug contained in the feeder container 41 is paid out one packet at a time. The drug discharged from the feeder container 41 falls downward through the discharge passage 33 provided inside the drum 31, and collects in the standby hopper 51 of the drug standby mechanism unit 50. When the medicines on the main unit 2 side and corresponding to the prescription for one packet are gathered in the standby hopper 51 in this way, the lid operation mechanism 53 is activated and the movable lid 52 is lifted upward. As a result, the lower end of the lid peripheral surface 52b of the movable lid 52 is separated from the inner peripheral surface of the standby hopper 51, and the drug dammed by the lid peripheral surface 52b rolls down toward the discharge port 56. .. The drug that has reached the discharge port 56 is discharged to the drug preparation unit 80 side via the collection hopper 70 provided below the standby hopper 51.

The medicine discharged from the hand-spraying unit 23 is supplied to the medicine preparation unit 80 side via the hand-spreading hopper 91.

When the drug to be discharged is in the subunit 120 on the subunit 3 side, the drug is transferred from the subunit 120 to the sub drug standby section 130 in the same manner as when the drug is in the main storage section 20 on the main unit 2 side. It will be paid out. That is, when prescribing the drug in the cassette 32 provided on the sub-storage unit 120 side, the drug contained in the feeder container 41 is dispensed one by one in the same manner as described above, and the sub-drug waits. It gathers in the standby hopper 51 of the mechanism unit 130. When the medicines to be prescribed from each cassette 32 installed in the sub-storage unit 120 are gathered in the drug standby mechanism 130, the lid operation mechanism 53 of the drug standby mechanism 130 operates and the movable lid 52 moves upward. It will be in a lifted state. As a result, the medicine collected in the medicine waiting mechanism unit 130 is discharged into the basin 145 of the transfer device 5 through the discharge port 56 and the sub hopper 135.

When the drug is discharged to the basin 145, the motor 146b of the inlet-side shutter mechanism 146 provided in the vicinity of the drug receiving portion 142 operates, the shutter plate 146a slides, and the suction means 141 also operates. Further, in the drug dispensing section 143, the discharge opening 140a of the pipeline 140 is closed by the peripheral surface of the shutter cylinder 147b, and many openings 147i provided on the peripheral surface of the shutter cylinder 147b are provided on the peripheral surface of the pipeline 140. It is in a state of communicating with the provided small opening 140b. After that, when the opening 146e of the shutter plate 146a communicates with the opening 145a provided on the side surface 145b of the basin 145, the medicine discharged into the basin 145 is drawn into the conduit 140. After that, the motor 146b operates in the opposite direction to the previous one, and the opening 145a of the box 145 is closed by the shutter plate 146a.

The drug drawn into the conduit 140 as described above further moves in the conduit 140 toward the drug dispensing unit 143 side. When the drug reaches the drug dispensing section 143, the suction means 141 is stopped. After that, the outlet side shutter mechanism 147 provided in the vicinity of the drug dispensing portion 143 is activated, and the dispensing opening 140a is opened. That is, by operating the motor 147c and rotating the shutter cylinder 147b in the circumferential direction, the opening 147i provided in the shutter cylinder 147b and the payout opening 140a of the pipeline 140 are in communication with each other.

In this state, if the hand-spraying unit 23 has a drug to be packaged together with the drug already dispensed in the first section 81a, this is dispensed from the hand-spraying unit 23 and via the hand-spraying hopper 91. It is paid out to the first section 81a. Further, in the third rotation state, if there is a drug to be dispensed from the main storage section 20 side to the fifth compartment 81a or a drug to be dispensed from the sub reservoir 120 side to the sixth compartment 81a, these are the collection hopper 70. It is paid out via the hand-made hopper 91.

When the dispensing of the drug to each section 81a is completed in the third rotation state as described above, the state of FIG. 15 (d) (hereinafter, also referred to as the fourth rotation state) and the state of FIG. 15 (e) (hereinafter, hereinafter, It is sequentially switched to the 5th rotation state). During this period as well, as in the case of the first to third rotation states described above, the chemicals discharged from the main storage unit 20, the sub storage unit 120, and the hand-spraying unit 23 are charged into each section 81a.

After that, when the dispensing of the drug is completed in the fifth rotation state, the drive mechanism 84 operates, and the partition forming body 81 further rotates in the counterclockwise direction by 60 degrees. As a result, as shown in FIG. 15 (f), the first section 81a arrives at a position corresponding to the opening 82c provided on the bottom surface of the drug preparation unit main body 82. At this time, the lever 81d provided at the position corresponding to the first section 81a comes into contact with the lever contact body 82d provided at the position adjacent to the opening 82c, and the shutter 81c opens. As a result, all the drugs collected in the first section 81a while the section forming body 81 makes one round counterclockwise are discharged to the drug packaging section 21 side via the packaging hopper 85.

The drug discharged from the drug preparation unit 80 to the drug packaging unit 21 is housed in a drug bag semi-formed in a bag shape by the bag forming mechanism 96 in advance by the packaging paper 98. After that, the medicine bag is sealed by the bag forming mechanism 96, and the packaging paper 98 is further fed toward the downstream side (obliquely downward side) by the sheet feeding mechanism 95.

Here, in the drug dispensing system 1 of the present embodiment, predetermined information regarding the drug or the like is printed in the printing unit at a timing (timing Z) before packaging the drug dispensed from the drug preparation section 80 in the drug packaging section 21. Printed by 99. More specifically, as described above, in the drug packaging unit 21 adopted in the present embodiment, the distance between the bag forming mechanism 96 and the printing unit 99 is set to be a length corresponding to three drug bags. Therefore, the timing (period Y) before the timing (timing X) when the drug is discharged from the first compartment 81a is required for the compartment forming body 81 to rotate by the amount corresponding to three of the compartments 81a (period Y). At the timing Z), that is, in the third rotation step described above, the printing unit 99 prints information about the drug and the like. In other words, the drug is discharged from the three compartments 81a located on the upstream side in the rotation direction of the compartment forming body 81 with respect to the first compartment 81a based on the timing at which the medicine is discharged from the first compartment 81a. Information about the medicine or the like contained in the first section 81a is printed by the printing unit 99 at the timing (timing Z) before the required period.

By sequentially rotating the compartment forming body 81 as described above, the drugs contained in the first to sixth compartments 81a are sequentially dispensed and packaged on the drug packaging section 21 side, and the main storage section 20 is used. The medicine is dispensed from the hand-spraying unit 23 and the sub-storage unit 120 to the first to sixth compartments 81a. The packaging paper 98, which is formed by packaging the drug in this way, is fed to the transport means 21b side obliquely downward in a series of states. The packing paper 98 sent to the transport means 21b side enters the inside of the casing 105 from the receiving port 107a provided in the receiving portion 105a. After that, the traveling direction of the packing paper 98, which was traveling diagonally downward in the housing of the main unit 2, is obliquely upward while being guided by the curvature of the casing 105 at the portion corresponding to the receiving portion 105a and the guide roller 107b. Can be switched. That is, the traveling direction of the packaging paper 98 is folded back at the receiving portion 105a.

The packing paper 98 that has entered the casing 105 comes into contact with the drive roller 110 and the belt 111 suspended from the drive roller 110 while being guided by the guide roller 107b. On the other hand, the drive roller 110 and the belt 111 operate by receiving power from a motor (not shown) provided in the casing 105. Further, a plurality of urging rollers 112 are provided at positions facing the drive roller 110 and the belt 111. The urging roller 112 is urged toward the belt 111 side and is in a state of being pressed against the belt 111 side. Therefore, when the packing paper 98 is sent out from the receiving portion 105a toward the straight line portion 105b and enters between the belt 111 and the urging roller 112, the packing paper 98 is driven by the urging roller 112 to drive the roller 110 or the belt 111. It will be in a state of being pressed toward the side. As a result, power is transmitted from the belt 111 to the packaging paper 98, and the packaging paper 98 is conveyed toward the bent portion 105c side diagonally upward along the straight portion 105b.

The packing paper 98 that has reached the bent portion 105c in this way is continuously conveyed along the bent portion 105c. Here, as described above, in the transport means 21b adopted in the present embodiment, the bent portion 105c may be linearly continuous with respect to the straight portion 105b, and the tip may be oriented toward the side panel 2b side. It is also possible to bend the main unit 2 toward the front panel 2a with respect to the straight portion 105b. Therefore, when the bent portion 105c is in a posture that is linearly continuous with respect to the straight portion 105b, the packing paper 98 conveyed along the straight portion 105b goes straight toward the side panel 2b side and the payout outlet. It is taken out from 2d to the outside of the main unit 2. On the other hand, when the bent portion 105c is bent and directed toward the front panel 2a side, the conveying direction of the packing paper 98 transported along the straight portion 105b is directed toward the front panel 2a side, and the packaging is separated from the payout port 2c. Paper 98 is paid out.

Here, in the drug dispensing system 1 of the present embodiment, an abnormality such as a paper jam in the packaging paper 98 in the drug packaging unit 21 can be detected by using the abnormality detecting mechanism 115. More specifically, in the drug packaging unit 21, the packaging paper 98 is transported by the transport means 21b, but in the transport means 21b and the packaging means 21a arranged on the upstream side of the transport means 21b, an abnormality in paper feeding should occur. If a problem such as the above occurs, the flow of the packaging paper 98 in the transport means 21b will be delayed.

On the other hand, in the conveying means 21b, among the plurality of urging rollers 112 provided, the urging rollers 112a located on the upstream side in the conveying direction of the packaging paper 98, that is, on the receiving portion 105a side, are placed on the side of the urging rollers 112a. On the other hand, there is a sub-roller 115a that can rotate independently. Further, a pinch roller 115b is arranged at a position facing the sub roller 115a. Therefore, when the packing paper 98 is flowing smoothly in the drug packaging section 21, the packing paper 98 passes between the sub roller 115a and the pinch roller 115b, and the pinch roller 115b is pushed by the packing paper 98. It will be turned and rotated. On the other hand, in the unlikely event that the flow of the packaging paper 98 is interrupted in the drug packaging section 21, the packaging paper 98 does not pass between the sub roller 115a and the pinch roller 115b, and the pinch roller 115b Does not rotate. Therefore, by detecting whether or not the pinch roller 115b is rotating normally with the rotary encoder 115d connected to the pinch roller 115b via the shaft 115c, the presence or absence of an abnormality in the paper feed of the packing paper 98 is detected. Can be detected. When the abnormality detection mechanism 115 detects a paper feed abnormality such as a paper jam in the packaging paper 98, the drug dispensing system 1 stops the series of operations described above.

Further, the main unit 2 and the subunit 3 adopted in the present embodiment are provided with the set defect detecting means 38, and this can be detected when the cassette 32 with respect to the drum 31 is not firmly mounted. Has been done. Specifically, when the cassette 32 protrudes from the locus J shown in FIG. 4C due to improper mounting, the cassette 32 abuts plate 38a constituting the set defect detecting means 38 as the drum 31 rotates. The contact plate 38a swings when it abuts against the switch 38b, and the switch 38b is turned on. Therefore, when the switch 38b is turned on, the drug dispensing system 1 stops the above-mentioned series of operations assuming that the cassette 32 is improperly mounted.

As described above, the drug dispensing system 1 of the present embodiment has a main unit 2 and a subunit 3, and the drug dispensed from the subunit 120 provided on the subunit 3 side is transferred by the transfer device 5. It can be transferred to the main unit 2 side. Then, not only the medicines paid out on the main unit 2 side but also the medicines paid out on the subunit 3 side can be packaged and paid out together in the medicine packaging section 21 provided on the main unit 2 side. can. Therefore, according to the drug dispensing system 1 of the present embodiment, a wide variety of drugs can be handled as much as the subunit 3 is provided.

Here, as described above, in the drug dispensing system 1, not only the main unit 2 but also the subunit 3 is provided with a large number of cassettes 32. Therefore, it is desirable that the drug dispensing system 1 has a configuration capable of accurately managing unique information (hereinafter, also referred to as container-specific information) about the feeder container 41 constituting each cassette 32. Specifically, in the drug dispensing system 1, as the container-specific information described above, data regarding the type and amount of the drug stored in the feeder container 41 of each cassette 32, replenishment of the drug in each feeder container 41, and the like are performed. It is desirable that the tag 49 can record data on the replenishment history such as the date and time when the drug was replenished, data on the usage history of each cassette, and the like. Further, the drug dispensing system 1 manages the drug stored in each feeder container 41 based on the container-specific information of each cassette 32 recorded on the tag 49, and the user determines the maintenance time of each cassette 32. It is desirable that the configuration is such that it can be notified to. Therefore, in order to meet such a demand, in the present embodiment, as shown in FIG. 20, the control means 170 provided for the operation control of the drug dispensing system 1 and the motor base 40 constituting each cassette 32 are built in. Data management including container-specific information can be sent and received, data can be updated and written, and data can be read from the tag 49 by the reader / writer 44 and the reader / writer 117c provided on the workbench 117. A system 180 is provided to manage the container-specific information of each cassette 32. Hereinafter, the data management method in the drug dispensing system 1 implemented by using the data management system 180 and the operation of the drug dispensing system 1 will be described in detail along with the drug filling procedure.

In the drug dispensing system 1, the main storage section 20 and the sub-storage section 120 are filled with the drug by removing the feeder container 41 of each cassette 32 assigned to each drug. Here, if the cassette 32 containing the drug to be filled is in a position where the feeder container 41 can be easily removed by the user, it can be removed as it is, but it may be in a position where it is difficult for the user to remove it. In such a case, the operation panel 118a is operated to display an interface for calling a cassette as shown in FIG. 22 (a), and a number individually assigned to each cassette 32 is input through the interface. Thereby, the feeder container 41 of the desired cassette 32 can be brought to a place where the user can easily remove it. When the type of the drug to be filled can be specified, first, the operation panel 118a is operated to display the interface for calling the drug name as shown in FIG. 22 (b).

The type of drug can be specified by reading with a reading means. Further, information on the type of the drug identified by this is recorded in the tag 49 by data communication between the control means 170 and the tag 49 included in the feeder container 41. Therefore, the drug dispensing system 1 does not require the operator to manually input the drug type when operating in the drug filling mode, and the information on the drug type can be more reliably obtained by that amount. And it can be surely recorded on the tag 49. In the above embodiment, the barcode reader 118b is used to read the barcode assigned to each drug to identify the type of drug, and an example having a function of automatically inputting data related to this type has been illustrated. The present invention is not limited to this, and may not have the function. Further, the barcode reader 118b may be capable of reading any kind of barcode including so-called one-dimensional barcode and two-dimensional barcode. Further, in the above embodiment, an example in which a barcode reader 118b capable of reading a barcode assigned to each type of drug is provided has been illustrated, but the present invention is not limited to this, and the barcode reader 118b is not limited thereto. Instead of, an appropriate one such as one that can read the signs created by using a color combination or the like, or one that can read the information recorded on the RFID tag or the like can be adopted.

As described above, in the drug dispensing system 1, only by arranging the feeder container 41 in the recess 117b of the work table 117, data communication can be performed in a non-contact state via the reader / writer 117c provided at the position corresponding to the recess 117b. It becomes a state. Therefore, the drug dispensing system 1 can enable data communication between the tag 49 and the control means 170 without the trouble of connecting the wiring to the feeder container 41, for example, and is applied to each feeder container 41. A series of operations such as updating, writing, and managing container-specific information can be performed smoothly. In the above embodiment, by adopting the RFID tag or RFID reader / writer for the tag 49 or the reader / writer 117c, the information recorded on the tag 49 is read out and the information is written on the tag 49 in a non-contact state. However, the present invention is not limited to this. That is, information may be read and written using another type of information recording medium or reader / writer, and even if data communication is possible in a non-contact format, data may be connected by connecting wiring or the like. It may be something that communicates.

Here, in the drug dispensing system 1 of the above-described embodiment, data unique to each feeder container 41 recorded on the tag 49 included in each feeder container 41, specifically, the type and amount of the stored drug, It is possible to read and write data such as the name of a drug replenishment worker. Therefore, in the drug dispensing system 1, a feeder container filled with a drug is appropriately selected from a plurality of motor bases 40 previously attached to the main storage section 20 of the main unit 2 and the sub-storage section 120 of the subunit 3. If the 41 is attached, the control means 170 can specify where the feeder container 41 containing the medicines required for the packaging is located, and the type and amount of the medicines according to the prescription can be dispensed. That is, according to the above configuration, the drug dispensing system 1 is not a so-called fixed address type device in which the mounting position of each feeder container 41 is fixed, but a so-called free device in which the feeder container 41 can be mounted at an arbitrary position. It can be an address type device.

Further, the drug dispensing system 1 is, for example, a semi-fixed address type device in which the motor base 40 to which the feeder container 41 can be attached is limited only to the feeder container 41 that houses the drug having a specific property. Is also possible. More specifically, the drug dispensing system 1 can handle a wide variety of drugs, but depending on the type of drug, the drug discharged from the feeder container 41 may easily bounce, roll, or fall at the payout destination. Some are prone to cracking and chipping due to impact. When handling drugs with such characteristics (hereinafter, these drugs are also referred to as specific drugs), the timing of packaging the drug is delayed until the timing when the bounce or rolling is likely to settle, or the impact of dropping is mitigated. If you do not take measures for this, there is a possibility that packaging defects will occur.

Regarding the feeder container 41 that stores the drug (specific drug) that may bounce, roll, crack, chip, etc. as described above, the lower position of the main storage section 20 and the sub storage section 120, and the circumstances as described above. It is desirable to install it in a place where it can be solved. Therefore, in such a situation, the drug dispensing system 1 can be used as the above-mentioned semi-fixed address type device. Specifically, the drug dispensing system 1 has the above-mentioned bounce with respect to the motor base 40, which is attached to the main storage unit 20 and the sub storage unit 120 in six stages in the vertical direction as shown in FIG. 36, for example. It is stipulated that the feeder container 41 containing a drug (specific drug) that may roll or the like should be attached to the motor base 40 in the area from the bottom to the second stage (hereinafter, also referred to as a fixed address area Fi). Can be done.

Further, the drug dispensing system 1 has a motor base in which the feeder container 41 containing a drug other than a specific drug has not only a fixed address area Fi but also an area outside this area Fi (hereinafter, also referred to as a free address area Fr). It is possible to specify that it may be attached to 40. Further, the feeder container 41 that can be attached to the free address area Fr can be further subdivided into two or more groups. Specifically, the feeder container 41 containing a drug other than the specific drug and which is not preferable to be dropped from a high place is provided in two stages above the fixed address area Fi. It is stipulated that the container should be installed in the area below the free address area Fr1, and the feeder container 41 containing the drug, which is assumed to have no problem due to dropping, is provided in two stages further above the free address area Fr1. It is also possible to specify that it may be attached to the motor base 40 of the address area Fr2. As shown in FIG. 37, the provision regarding the correspondence between the motor base 40 and the feeder container 41 in each region is stored in the storage means in the control device 190 as the container mounting database 193 (counter-relationship regulation unit). It is constructed in the control means 190 by such means.

As described above, a plurality of installation areas of a large number of motor bases 40 provided in the main storage unit 20 and the sub storage unit 120 are set according to the height, such as a fixed address area Fi and a free address area Fr (Fr1, Fr2). When classifying into the area (container mounting area), the correspondence between the motor base 40 and the feeder container 41 is the mounting upper limit of the feeder container 41 set according to the type of the drug contained in the feeder container 41. It may be defined in relation to the container mounting area at the height. Specifically, the bounce coefficient that quantifies the correlation between the height at which the drug contained in each feeder container 41 is dropped (drop height) and the degree of bounce, and the relationship between the drop height and rolling are coefficiented. The correspondence relationship between the motor base 40 and each feeder container 41 may be determined in consideration of a part or all of numerical values and coefficients such as a rolling coefficient and a drop height at which cracks and chips are less than a predetermined probability.

In the present embodiment, labels corresponding to the feeder container 41 and the motor base 40 are attached so that the operator who attaches / detaches the feeder container 41 can easily identify the provisions stored in the container mounting database 193 described above. , Associated. Specifically, the motor base 40 and the feeder container 41 containing the specific drug in the fixed address region Fi are attached with a specific label A colored in blue, for example. Further, the motor base 40 in the free address area Fr1 is attached with a specific label B colored in green, for example, and the label B is also attached to the feeder container 41 which may be installed in either the free address area Fr1 or the fixed address area Fi. Is attached. Similarly, the motor base 40 in the free address area Fr1 is attached with a specific label C colored in white, for example, and the feeder container may be installed in any of the free address areas Fr1 and Fr2 and the fixed address area Fi. Label C is also attached to 41. Therefore, the operator can intuitively understand that the feeder container 41 should be attached to the area with the same label as the label attached to the feeder container 41 to be attached, or to the area below this. ..

When the drug dispensing system 1 is a device of the semi-fixed address type described above as described above, for example, the control means 190 shown in FIG. 37 may be adopted instead of the control means 170 described above. Hereinafter, the drug dispensing system 1 that employs the control means 190 will be described focusing on the configuration and operation of the control means 190. In the following description, for simplification of the description, an example in which the regions of the main storage unit 20 and the sub storage unit 120 are classified into two regions, a fixed address region Fi and a free address region Fr, according to the height will be described. ..

In the control means 190, in addition to the functions of the control means 170 described above, a feeder container 41 (hereinafter, also referred to as a specific feeder container 41x) to be set in the motor base 40 in the fixed address area Fi is mounted on the wrong motor base 40. It has a determination unit 191 having a function of executing a correct / incorrect determination operation for confirming whether or not the container is correct. That is, when the feeder container 41 is attached to the motor base 40, the control means 190 performs a correctness determination operation by the determination unit 191 and determines whether or not the attached feeder container 41 is the specific feeder container 41x. In addition, the specific feeder container 41x is provided in an area outside the fixed address area Fi (hereinafter, also referred to as a free address area Fr), specifically, in two stages above the fixed address area Fi. A correct / incorrect judgment operation is performed to determine whether or not the motor base 40 is erroneously mounted by checking whether the motor base 40 in the address area Fr1 or the free address area Fr2 provided in two stages further above the address area Fr1 is erroneously mounted. Can be implemented. Hereinafter, the correctness determination operation will be described in detail.

(Correct / wrong judgment operation)
In the drug dispensing system 1 provided with the control means 190, when the feeder container 41 is mounted on the motor base 40, a correctness determination operation is performed according to the control flow shown in FIG. 38. Specifically, when the erroneous mounting determination operation is started, the container mounting database 193 described above in steps 1-1 to 1-3, the region where the motor base 40 to which the feeder container 41 is mounted exists, and the motor base Based on the type of drug read from the tag 49 of the feeder container 41 attached to the 40, the determination unit 191 confirms whether or not there is an erroneously attached feeder container 41 contrary to the provisions of the container mounting database 193. ..

More specifically, first, in step 1-1, the feeder container 41 mounted on the motor base 40 is provided by the reader / writer 44 provided for each motor base 40 in the main storage unit 20 and the sub storage unit 120. Data communication is performed between the tag 49 and the control means 190. Thereby, the control means 190 specifies in which region of the fixed address region Fi and the free address region Fr the motor base 40 to which the feeder container 41 is attached exists. At the same time, whether or not the feeder container 41 mounted on the motor base 40 is the specific feeder container 41x, that is, whether or not the drug in the feeder container 41 is a specific drug that may be cracked or chipped. Is confirmed by the control means 190. After that, the control flow shifts to step 1-2.

When the control flow shifts to step 1-2, the determination unit 191 of the control means 190 determines that the drug contained in the feeder container 41 confirmed in step 1-1 is a specific drug that may be cracked or chipped. It is confirmed whether or not there is. Here, when the drug is not a specific drug, the feeder container 41 containing the drug may be mounted on the motor base 40 existing in either the fixed address region Fi or the free address region Fr. Therefore, when it is confirmed in step 1-2 that the type of the drug is not a specific drug, the control flow proceeds to step 1-6, and the attached feeder container 41 is in a normal position (a state in which the attached feeder container 41 is attached. It is determined that the device is normally mounted), and a series of control flows is completed.

On the other hand, in step 1-2, if the drug contained in the feeder container 41 attached to the main storage section 20 or the sub storage section 120 is determined to be a specific drug, the control flow is changed to step 1-3. Transition. In step 1-3, it is confirmed whether or not the motor base 40 to which the feeder container 41 is attached is in the fixed address area Fi of the main storage unit 20 and the sub storage unit 120. Here, when the feeder container 41 is mounted on the motor base 40 in the fixed address area Fi, even if the drug (specific drug) in the feeder container 41 is discharged, the above-mentioned problems due to splashing, cracking, etc. Is not expected to occur. Therefore, in this case, the control flow is advanced to step 1-6, it is determined that the feeder container 41 is mounted at a normal position, and a series of control flows is completed.

On the other hand, when it is confirmed in step 1-3 that the motor base 40 to which the feeder container 41 is attached is not in the fixed address area Fi but in the free address area Fr, the drug is administered from the feeder container 41. By paying out (specific drug), there is a concern that problems may occur due to splashing or cracking. Therefore, in this case, the control flow is advanced to steps 1-4, and it is determined that the feeder container 41 is not mounted in the normal position and is in an erroneously mounted state. After that, the control flow shifts to step 1-5, and a display warning that the operation panel 118a provided on the front surface of the main body of the main unit 2 is in the erroneously mounted state is displayed, and a series of control flows is completed.

In the drug dispensing system 1 provided with the control means 190, the drug packaging operation in the normal operation mode can be performed according to the control flow shown in FIG. 39 by utilizing the determination result by the correctness determination operation described above. Hereinafter, the packaging operation in the normal operation mode, which is carried out by utilizing the judgment result by the correctness judgment operation, will be described.

(Packaging operation using the judgment result of correct / incorrect judgment operation)
The drug dispensing system 1 provided with the control means 190 starts operation in the normal operation mode when the prescription data for designating the type and amount of the drug to be packaged, the number of packages, and the like are input to the control means 190. do. When the operation in the normal operation mode is started, first, in step 2-1 the mounting state of the feeder container 41 with respect to the motor base 40 attached to the drums of the main storage unit 20 and the sub storage unit 120 is confirmed. After that, when the control flow shifts to step 2-2, the feeder container 41 (hereinafter, also referred to as the packaging feeder container 41y) containing the drug to be packaged based on the prescription data input earlier becomes the main storage unit 20. Alternatively, it is confirmed whether or not it is attached to the sub storage unit 120. Here, if there is a shortage in the packaging feeder container 41y, the control flow shifts to step 2-7, and information indicating an error (feeder container insertion error) as shown in FIG. 40 is displayed on the operation panel 118a. Will be done. Further, in step 2-7, the packaging operation is stopped. After that, the control flow shifts to step 2-6 described later.

On the other hand, if all the packaging feeder containers 41y are attached in step 2-2, the control flow proceeds to step 2-3. In step 2-3, not only the feeder container 41y for packaging but also all the feeder containers 41 mounted in the main storage section 20 and the sub storage section 120 are checked for erroneous mounting, or the control flow shown in FIG. 38 described above. Is confirmed according to. It is assumed that there is erroneous mounting in step 2-3, that is, problems such as splashing and cracking that should normally be mounted in the fixed address area Fi in the main storage section 20 and the sub storage section 120 are assumed. When it is confirmed that the feeder container 41 (specific feeder container 41x) containing the specific drug is attached to the free address region Fr, the control flow shifts to step 2-8.

In step 2-8, it is confirmed whether or not the misplaced feeder container 41 contains the drug to be packaged (packaging feeder container 41y). Here, if the feeder container 41 that is erroneously installed corresponds to the feeder container 41y for packaging, if the packaging of the drug is continued as it is, the dispensed drug will bounce or roll at the payout destination. Inconveniences such as poor packaging and cracking or chipping of the drug may occur. Therefore, in this case, the control flow is shifted to step 2-10, and an error (feeder container erroneous mounting error) indicating that the feeder container 41 (specific feeder container 41x) erroneously mounted in the free address area Fr exists. The information shown is displayed on the operation panel 118a as shown in FIG. 42, and the packaging operation is stopped until the erroneously mounted feeder container 41 is mounted in the fixed address area Fr.

On the other hand, if it is determined in step 2-8 that the erroneously mounted feeder container 41 does not correspond to the packaging feeder container 41y, the drug is discharged from the erroneously mounted feeder container 41 in a series of packaging operations. There is no such thing as a container. Therefore, even if the packaging operation is continued in a state where the feeder container 41 to be attached to the fixed address area Fi is erroneously attached, the above-mentioned problems due to splashing, rolling, cracking, chipping, etc. of the drug do not occur. is assumed. Therefore, in this case, in step 2-9, after a message prompting the elimination of erroneous mounting (mismounting elimination promotion message) as shown in FIG. 41 is displayed on the operation panel 118a, the control flow is changed to step 2-4. The packaging operation is continued while the erroneous mounting elimination promotion message displayed in step 2-9 is displayed on the operation panel 118a.

When it is determined in step 2-3 described above that the feeder container 41 is not erroneously installed, or when it is determined that the feeder container 41 erroneously installed in step 2-8 does not correspond to the packaging feeder container 41y. The control flow proceeds to step 2-4. In step 2-4, it is confirmed whether the packaging feeder container 41y containing the drug to be packaged has not been removed during the series of flows proceeding from step 2-1 described above. Here, when it is confirmed that the packaging feeder container 41y has been removed, the control flow proceeds to step 2-11, and information indicating an error indicating that fact (feeder container identification error) is shown in FIG. 43. As shown, it is displayed on the operation panel 118a, and the packaging operation is stopped until the extracted packaging feeder container 41y is reattached. On the other hand, if it is determined in step 2-4 that the packaging feeder container 41y has not been removed, the control flow proceeds to step 2-5, and the packaging operation is performed. After that, the control flow proceeds to step 2-6, and it is confirmed whether all the drugs to be packaged have been packaged based on the prescription data input at the start of the drug packaging operation in the normal operation mode. Here, if the prescription data indicates that the drug has not been packaged, the control flow is returned to step 2-2. On the other hand, when the packaging of all the drugs is completed, a series of control flows is completed.

As described above, when the control means 190 is adopted in the drug dispensing system 1, the correctness determination operation is performed according to the control flow shown in FIG. 38, and whether the feeder container 41 is erroneously mounted in the container mounting portion that should not be mounted originally. It can be determined whether or not. Further, in the drug dispensing system 1, as shown in the control flow of FIG. 39, even when the feeder container 41 is erroneously mounted, the erroneously mounted feeder container 41 accommodates the drug to be packaged. If it does not correspond to the one (feeder container for packaging 41y), there is no problem in packaging the drug, so the drug will be continuously dispensed to improve the work efficiency of the drug dispensing and packaging operation. ing. On the other hand, if the mis-installed feeder container 41y for packaging contains a drug that may cause problems such as splashing and cracking as described above, the dispensing and packaging of the drug are stopped. It is supposed to be. Therefore, if the drug dispensing system 1 is configured as described above, even if there is an erroneously mounted feeder container 41, the drug splashes or cracks, etc., while minimizing the decrease in work efficiency. It is possible to prevent packaging defects caused by the problem of.

In the example shown in the above embodiment, the motor base 40 to which the feeder container 41 can be mounted is provided in multiple stages in the vertical direction, and has two stages of fixed address area Fi and free address area Fr according to the height. It is defined in the area (container mounting area). Further, in the container mounting database 193, the container mounting area in which the correspondence relationship between the motor base 40 and the feeder container 41 to be attached to the motor base 40 is at a height that becomes the mounting upper limit of the feeder container 41 set according to the type of the drug. It is stipulated in relation to. That is, the area serving as the mounting upper limit of the feeder container 41 containing the specific drug, which is expected to have problems such as splashing and cracking, is defined as the fixed address area Fi. Further, the area serving as the mounting upper limit of the feeder container 41 containing the chemicals having relatively few problems such as splashing and cracking is defined as the free address area Fr.

However, the provision (classification) regarding the relationship with the container mounting area at the height that is the mounting upper limit of the feeder container 41 specified in the container mounting database 193 is not limited to the above, and is not limited to the above. The area where the motor base 40 is provided may be divided into multiple stages and may be further divided into multiple stages according to the height. Specifically, as described above, the free address area Fr may be further classified into two areas Fr1 and Fr2, and may be classified into three stages as a whole, or may be further classified into multiple stages. In this case, in the container mounting database 193, the correspondence relationship between the motor base 40 and the feeder container 41 to be attached to the motor base 40 is a region (container) at a height that is the upper limit of attachment of the drug supply container set according to the type of the drug. When the feeder container 41 is mounted on the motor base 40 of the container mounting area located above the container mounting area at the height of the mounting upper limit, which is defined in relation to the mounting area), the correctness determination operation is performed. When it is determined that the container is erroneously mounted and the feeder container 41 is mounted on the motor base 40 of the container mounting area located in the container mounting area at a height equal to or lower than the above-mentioned mounting upper limit, the feeder container 41 is normally mounted by the correct / wrong determination operation. By configuring the configuration so that it is determined that the feeder container 41 is in the mounted state, the mounted state of the feeder container 41 can be managed in a further subdivided manner.

Regarding the height (container mounting area) that is the upper limit of mounting of the feeder container 41 described above, the bounce, rolling, cracking, and chipping when the drug is dropped are coefficiented for each type of drug, and the class is classified for each drug. The divided ones may be set in advance as a reference, or the height (container mounting area) which is the upper limit of mounting may be sequentially determined by the control means 190 according to these coefficients and classes.

As shown by the alternate long and short dash line in FIG. 37, the drug dispensing system 1 described above has a search function for searching and selecting the motor base 40 to which the feeder container 41 determined to be erroneously installed by the correctness determination operation by the control means 190 is to be installed. A search unit 192 may be provided. Specifically, it is attached to the feeder container 41 by removing the feeder container 41 determined to be erroneously installed by the correctness determination operation and fitting it into the recess 117b of the work table 117a provided on the work table 117 on the main unit 2 side. The information recorded in the tag 49 is read out by data communication between the tag 49 and the reader / writer 117c, search conditions are set, and a motor base 40 suitable for mounting the feeder container 41 is searched for. It may be configured to be searched and selected by the unit 192. Further, it is preferable that the search conditions are appropriately displayed on the operation panel 118a or the like as shown in FIG. 44. On the other hand, instead of reading the information of the feeder container 41 erroneously mounted by the data communication between the tag 49 and the reader / writer 117c and setting the search condition, the operator manually searches the search condition via the operation panel 118a. Is input, and the search unit 192 may search based on this. In this case, for example, it is preferable to display the search condition setting screen as shown in FIG. 44 on the operation panel 118a so that input can be performed as appropriate.

Further, when the position of the motor base 40 suitable for mounting the misplaced feeder container 41 as described above is searched, the place where the operator can attach / detach the feeder container 41 (detachment work position). The main storage unit 20 and the sub storage unit 120 may be operated so that the motor base 40 selected in) arrives. According to such a configuration, the work of attaching / detaching the misplaced feeder container 41 becomes even easier.

As described above, in the present embodiment, the drug dispensing system 1 is constructed by combining the main unit 2 and the subunit 3, and not only the main storage unit 20 but also the sub storage unit 120 is provided with a large number of cassettes 32. ing. Therefore, when constructing the drug dispensing system 1, it is desirable to read / write and manage the container-specific information regarding the feeder container 41 of each cassette 32 as in the above embodiment. In the above embodiment, an example in which the drug dispensing system 1 is constructed by combining the main unit 2 and the subunit 3 is illustrated, but the present invention is not limited to this, and corresponds to the main unit 2. Even when only the drug dispenser is used, it is possible to accurately read / write and manage the container-specific information.

The drug dispensing system 1 does not require the drug packaging unit 21 on the subunit 3 side. Therefore, in the drug dispensing system 1, it is possible to make the device configuration compact and minimize the installation area as compared with the case where a plurality of devices corresponding to the main unit 2 are provided. Further, if a configuration such as the drug dispensing system 1 is adopted, a large amount of various drugs can be accommodated on the subunit 3 side as much as the one corresponding to the drug packaging section 21 can be omitted on the subunit 3 side. It is also possible. Further, the drug dispensing system 1 does not require a configuration corresponding to the drug packaging unit 21 on the subunit 3 side, so that the device configuration can be simplified and the maintenance effort can be minimized.

Since the transfer device 5 adopted in the drug dispensing system 1 has a pipeline 140 for transferring the drug and sucks the drug charged into the pipeline 140, the transfer device 5 is dispensed on the subunit 3 side. The drug can be smoothly conveyed toward the main unit 2 side. Further, since the transfer device 5 sucks and transports the drug, the drug can be transported by an arbitrary transport path by appropriately bending the pipeline 140. Therefore, the drug dispensing system 1 has a high degree of freedom in the device configuration and layout of the main unit 2 and the subunit 3.

The transfer device 5 described above sucks and transfers the drug charged into the basin 145 of the drug receiving section 142 connected to the pipeline 140 to the drug dispensing section 143, but the present invention is limited to this. It may be transferred by pumping from the drug receiving unit 142 side toward the drug discharging unit 143 side. Further, the transfer device 5 is provided with only one pipeline 140, but the present invention is not limited to this, and has a multi-system transport route including a larger number of pipelines 140. It may be a thing.

In the drug dispensing system 1 of the present embodiment, the tag 49 is attached to each cassette 32 set in the main storage unit 20 and the sub storage unit 120, and the tag 49 is attached to the tag 49 by the reader / writer 117c provided on the work table 117. Data can be sent and received between, and data can be updated and written. Therefore, the drug dispensing system 1 has data on the type and amount of the drug contained in each cassette 32 in the tag 49, and data on the replenishment history such as the person who replenished the drug in each cassette 32 and the date and time of replenishment. , Various data such as data related to the usage history of each cassette 32 can be recorded. Further, based on the data recorded in the tag 49, it is possible to manage the medicines contained in each cassette 32, notify the user of the maintenance time of each cassette 32 itself, and the like.

In the above embodiment, an example in which the tag 49 is attached to the feeder container 41 of each cassette 32 and the reader / writers 44 and 117c are provided on all the motor bases 40 and the workbench 117 has been illustrated. It is not limited. That is, the drug dispensing system 1 may have a configuration in which all cassettes 32 do not have tags 49 and some or all motor bases 40 do not have a reader / writer 44. Similarly, the drug dispensing system 1 may not include a reader / writer 117c. Further, the drug dispensing system 1 may be configured such that only a part of the cassettes 32 for which the amount of the drug should be managed and the like are provided with the tag 49.

As described above, in the feeder container 41 of the cassette 32, the size of the opening 47 for dispensing the drug can be adjusted according to the size of the drug contained therein by appropriately replacing the opening attachment 41b. .. Further, the feeder container 41 can be appropriately replaced with a rotor 48 whose groove 48a is suitable for the size of the medicine contained therein. Therefore, the cassette 32 can handle various sizes of chemicals by appropriately replacing the opening attachment 41b and the rotor 48.

In the above embodiment, an example in which the feeder container 41 has an opening attachment 41b and a rotor 48 that can be appropriately replaced according to the size of the drug has been illustrated, but the present invention is not limited thereto. Specifically, the feeder container 41 may be provided with an opening 47a having a certain size, or the rotor 48 may be non-replaceable, as in the conventionally known one.

Further, in the drug dispensing system 1, considering that there is a packaging paper 98 having a length corresponding to n packages of drug bags (3 packets in the present embodiment) between the bag forming mechanism 96 and the printing unit 99, it is considered. The amount of the compartment forming body 81 corresponding to n (three in the present embodiment) of the compartment 81a is equal to the timing (timing X) when the medicine is discharged from the compartment 81a through the opening 82c in the medicine preparation unit 80. Information about the drug or the like is printed by the printing unit 99 at a time point (timing Z) before the period (period Y) required for rotation. Further, the chemicals discharged from the main storage unit 20 and the sub storage unit 120 are charged into the compartment 81a at a timing before the timing Z of printing on the packaging paper 98. That is, in the drug dispensing system 1, printing is performed on the packaging paper 98 on condition that the drug is charged from the main storage section 20, the sub-storage section 120, and the hand-spreading unit 23 into the drug preparation section 80, so that the drug is printed. If the drug is poorly dispensed to the preparation unit 80, the packaging paper 98 is not printed. Therefore, in the drug dispensing system 1, it is easy to check the presence or absence of printing failure on the packing paper 98 from the main storage section 20, the sub storage section 120, and the hand-spraying unit 23 to the drug preparation section 80 by simply checking the presence or absence of printing on the packing paper 98. It can be audited accurately. Further, according to the above-described configuration, when the chemicals to be packaged in the packaging paper 98 are insufficient or absent, unnecessary printing is not applied to the packaging paper 98, and the packaging paper 98 is packaged accordingly. It is possible to prevent the paper 98 from being wasted.

In the above embodiment, at the timing before the timing Z, the medicine is discharged from all of the main storage unit 20, the sub storage unit 120, and the hand-spraying unit 23 constituting the drug dispensing means, and the drug is discharged into each section 81a. However, the present invention is not limited to this. Specifically, with respect to the medicines to be paid out from a part of the main storage part 20, the sub storage part 120, and the hand-spraying unit 23 constituting the medicine dispensing means, each section 81a is performed at a timing after the timing Z. It may be configured to be paid out to. More specifically, for example, since the hand-spraying unit 23 is provided for packaging the drug charged by the user himself / herself, a defective charging of the drug from the hand-spraying unit 23 into each section 81a occurs. It is considered difficult. Therefore, when there is such a situation, the timing of dispensing the drug in the one constituting a part of the drug dispensing means may be later than the above-mentioned timing Z.

The drug dispensing system 1 according to the above embodiment employs a circular partition forming body 81 of the drug preparing unit 80 in which a plurality of compartments 81a are arranged in the circumferential direction, and rotates the partition forming body 81 relative to the opening 82c. The drug is discharged from each section 81a by allowing the drug to be discharged. Therefore, according to the above configuration, the space required for the operation of the partition forming body 81 can be minimized, and the device configuration can be made compact. The drug preparation unit 80 is not limited to the above embodiment. For example, the compartment forming body 81 is assumed to have a plurality of compartments 81a arranged linearly, and the compartments 81 are linearly moved with respect to the opening 82c. The drug may be sequentially discharged from each section 81a.

Further, as described above, the drug dispensing system 1 has a set defect detecting means 38 in the main unit 2 and the subunit 3. The set defect detecting means 38 is not like a conventionally known optical sensor, but is a switch 38b when the cassette 32 abuts against the abutting plate 38a and the abutting plate 38a swings as the drum 31 rotates. Is turned on, so to speak, it adopts a mechanical configuration. Therefore, according to the set defect detecting means 38 described above, it is possible to accurately detect the mounting defect of the cassette 32 without being affected by dust or the like as in the case where the optical sensor is adopted.

The drug dispensing system 1 exemplifies an example in which a mechanical set defect detecting means 38 is provided in both the main unit 2 and the subunit 3, but the present invention is not limited to this, and one of them is used. The set defect detecting means 38 may be provided only in the unit, or the set defect detecting means 38 may be used in combination with a conventionally known detecting means such as an optical sensor.

The drug dispensing system 1 is provided with an abnormality detection mechanism 115 in the transport means 21b of the drug packaging unit 21, whereby it is possible to detect an abnormality in paper feeding represented by a paper jam of the packaging paper 98. That is, the abnormality detecting means 115 shown in the above embodiment has a pinch roller 115b that can rotate independently of the conveying means 21b, and the rotation of the pinch roller 115b causes the rotary encoder 115d to rotate during the operation of the conveying means 21b. It is possible to detect the presence or absence of paper feed failure depending on whether or not it is detected by. Therefore, in the drug dispensing system 1 of the present invention, it is possible to minimize the occurrence of waste of the packaging paper 98 and the drug due to the occurrence of poor paper feeding of the packaging paper 98. In the above embodiment, the abnormality detection mechanism 115 is a straight portion 105b of the casing 105 constituting the transporting means 21b so that the abnormality of the paper feed in the drug packaging portion 21 can be detected as soon as possible. Although the configuration provided at the position unevenly distributed on the upstream side in the feeding direction of the paper 98 has been illustrated, the present invention is not limited to this, and the configuration may be provided at a position on the downstream side of the paper 98.

In the above embodiment, the drug packaging unit 21 can appropriately bend the bent portion 105c located at the end portion of the casing 105 constituting the transport means 21b with respect to the straight portion 105b. Therefore, in the drug payout system 1, the packing paper 98 containing the drug can be taken out from the payout port 2c or 2d of the main unit 2, whichever is more convenient. Although the above-mentioned transport means 21b can appropriately bend the bent portion 105c, it may be configured not to have a bent portion 105c.

Further, in the above embodiment, an example in which the drug dispensing system 1 is configured by combining the main unit 2 and the subunit 3 has been illustrated, but the present invention is not limited to this, and the main unit 2 is used alone. It may be one.

The drug dispensing system 1 described above may have a configuration in which a transfer device 5 is separately prepared in addition to the main unit 2 and the subunit 3 and installed so as to bridge between the two, but the subunit 3 may be installed in advance as a transfer device. 5 may be incorporated, and this may be connected to the main unit 2 for expansion as needed. That is, the subunit 3 may include the transfer device 5 as a part of the configuration or may not include the transfer device 5.

In the above embodiment, an example in which a transfer device 5 of a type that sucks and transfers a drug paid out on the subunit 3 side is adopted has been illustrated, but the present invention is not limited to this, and for example, FIG. 25 The transfer device 210 shown in the above may be adopted.

More specifically, the transfer device 210 is roughly classified into a support unit 220 and a drive unit 230. As shown in FIG. 25, the support portion 220 has a support shaft 221 and a base portion 222. The support shaft 221 has a flange 223 provided at the end thereof, and can be erected substantially vertically by screwing the flange 223.

The slide member 244 has a belt fixing portion 244a and a sliding body fixing portion 244b. The slide member 244 is fixed to the timing belt 248 by sandwiching the timing belt 248 in the belt fixing portion 244a. Further, the sliding body fixing portion 244b is exposed from the opening 236d of the first sliding body 236 to the surface side (upper side) of the top portion 236a, and is directed toward the longitudinal direction of the first sliding body 236 along the opening 236d. It is said that it can slide linearly. The sliding body fixing portion 244b is fixed to the top portion 237a of the second sliding body 237, which will be described in detail later, with screws or the like.

The second sliding body 237 is provided for delivering and delivering the drug, and is arranged so as to cover the first sliding body 236 as shown in FIGS. 26 and 27. A slide member 244 of the first sliding body 237 is fixed to one end side in the longitudinal direction of the second sliding body 237 (hereinafter, also referred to as a base end side if necessary) by a screw or the like. Therefore, the second sliding body 237 is in a state of being connected to the first sliding body 236 via the slide member 244.

As shown in FIGS. 28 and 31, the second sliding body 237 includes a drug accommodating portion 237d in addition to the top portion 237a and the side portions 237b and 237c. The top portion 237a is a long and flat portion, and side portions 237b and 237c are provided at both ends in the width direction. The side portions 237b and 237c face each other.

The guide rails 250 and 251 extend linearly along the longitudinal direction of the second sliding body 237, respectively. As shown in FIG. 28, the guide rails 250 and 251 are fitted with guide rollers 245 and 245 provided on the side portions 236b and 236c of the first sliding body 236. Therefore, the second sliding body 237 can move relative to the length direction of the first sliding body 236. Further, as described above, the second sliding body 237 is connected to the first sliding body 236 via the slide member 244. Therefore, the second sliding body 237 moves linearly with respect to the first sliding body 236 in conjunction with the sliding movement of the slide member 244.

The drug accommodating portion 237d is provided on one end side in the longitudinal direction of the second sliding body 237 (hereinafter, also referred to as a tip side if necessary). The drug accommodating portion 237d is a box-shaped portion having an opening in the top portion 237a. The bottom surface of the drug accommodating portion 237d is closed by the shutter 255. The shutter 255 is slidably attached in the longitudinal direction of the second sliding body 237. By opening the shutter 255, the drug accommodating unit 237d can discharge the drug contained therein downward.

Subsequently, the operation of the transfer device 210 will be described in detail. By operating the swivel drive motor 225 provided on the support portion 220, the transfer device 210 can swivel each drug delivery unit 231 around the swivel shaft 234. Further, in the transfer device 210, by operating the drive motor 235e provided in each drug delivery unit 231, the sliding base 235 and the first and second sliding bodies 236 and 237 are linearly aligned as shown in FIG. 25 (a). A state in which the first and second sliding bodies 236 and 237 are retracted toward the sliding base 235 and the total length is shortened as shown in FIG. 25 (b). Hereinafter, it can also be referred to as a contracted state).

Explaining in more detail the operation of the drug delivery unit 231 accompanying the operation of the drive motor 235e, when the drive motor 235e operates when the transfer device 210 is in the contracted state as shown in FIG. 25 (b), this power slides. In the dynamic base 235, it is transmitted to the drive pulley 235h via the drive belt 235i provided on the back surface side of the top portion 235a, and this rotates together with the shaft 235g. Along with this, the drive gear 235j attached to the shaft 235g also rotates on the surface side of the top portion 235a. When the drive gear 235j rotates counterclockwise around the shaft 235g when the top portion 235a is viewed from above, the driven rack gear 241 of the first sliding body 236 meshing with the drive gear 235j becomes a sliding base. It is delivered linearly from the base end side of the 235 toward the tip end side. As a result, the entire first sliding body 236 together with the driven rack gear 241 slides from the base end side to the tip end side of the sliding base 235.

Here, as described above, the timing belt 248 suspended between the pulleys 242 and 243 in the first sliding body 236 is fixed by the belt fixing member 235k erected on the top portion 235a of the sliding base 235. .. Further, a slide member 244 is fixed to the timing belt 248, and the slide member 244 and the timing belt 248 operate integrally. When the transfer device 210 is in the contracted state, the slide member 244 is unevenly distributed on the base end side of the first sliding body 236, that is, on the pulley 242 side. On the other hand, the belt fixing member 235k is located at a position unevenly distributed on the tip end side of the first sliding body 236, that is, on the pulley 243 side. That is, the belt fixing member 235k and the slide member 244 are in an oblique (diagonal) positional relationship with the timing belt 248 interposed therebetween. Therefore, when the first sliding body 236 slides from the base end side to the tip end side of the sliding base 235, the pulley 242 approaches the belt fixing member 235k side accordingly. On the other hand, the slide member 244 is on the pulley 243 side along the opening 236d provided in the top portion 236a of the first sliding body 236 while maintaining the positional relationship of the belt fixing member 235k and the belt fixing member 235k with the timing belt 248 interposed therebetween. That is, it advances toward the tip end side of the first sliding body 236.

When the slide member 244 moves toward the tip end side of the first sliding body 236, the second sliding body 237 integrated via the slide member 244 also slides toward the tip end side of the first sliding body 236. Then, as shown in FIG. 26, when the slide member 244 reaches the tip end side (pulley 243 side) of the first sliding body 236, both the first and second sliding bodies 236 and 237 move in the longitudinal direction of the drug delivery unit 231. It becomes a fully stretched state, that is, a stretched state.

On the other hand, when the first and second sliding bodies 236 and 237 are pulled back to the sliding base 235 side in the extended state as shown in FIG. 26, the total length of the drug delivery unit 231 is shortened (contracted state). The drug delivery unit 231 operates in the reverse procedure of the above. That is, in the contracted state, the drive motor 235e operates so that the rotating shaft rotates in the direction opposite to that in the extended state. Along with this, the power of the motor 235e is transmitted to the drive gear 235j via the timing belt 248, the drive pulley 235h, and the shaft 235g. The drive gear 235j rotates in a direction opposite to the rotation direction when the drug delivery unit 231 is in the extended state. That is, the drive gear 235j rotates in the clockwise direction when the top portion 235a is viewed from above. As a result, the driven rack gear 241 meshing with the drive gear 235j moves linearly toward the base end side of the sliding base 235, and the entire first sliding body 236 moves at the base end of the sliding base 235. Slide from the side to the tip side.

When the first sliding body 236 slides as described above, the pulley 243 on the tip end side of the first sliding body 236 approaches the belt fixing member 235k side. In conjunction with this, the slide member 244, which has an oblique positional relationship with the belt fixing member 235k across the timing belt 248, is first along the opening 236d provided in the top portion 236a of the first sliding body 236. It moves toward the pulley 242 side on the base end side of the sliding body 236. As a result, the second sliding body 237 connected to the first sliding body 236 via the slide member 244 also slides toward the base end side of the sliding base 235 in the same manner as the first sliding body 236. Then, when the slide member 244 reaches the base end side (pulley 242 side) of the first sliding body 236, both the first and second sliding bodies 236 and 237 are in a contracted state contracted in the longitudinal direction of the drug delivery unit 231. ..

The transfer device 210 is arranged at the boundary between the main unit 2 and the subunit 3 in the same manner as the transfer device 5 adopted in the above embodiment. More specifically, as shown in FIG. 25, the transfer device 210 is provided on the bottom surface of the housing constituting the subunit 3 and on the wall surface 4a forming the boundary between the subunit 3 and the main unit 2. The flange 223 is screwed and installed at a position adjacent to the communication port 4b. Therefore, as shown in FIG. 25, when the drug delivery unit 231 is in the extended state in a posture in which the longitudinal direction of the drug delivery unit 231 is substantially orthogonal to the wall surface 4a, the transfer device 210 is one of the drug delivery units 231 (hereinafter, hereinafter, The delivery unit (also referred to as 231a) is in a state in which the second sliding body 237 protrudes toward the main unit 2 side beyond the wall surface 4a. Further, the other drug delivery unit 231 (hereinafter, also referred to as a delivery unit 231b) is in a state in which the second sliding body 237 protrudes in the subunit 3 in the direction opposite to that of the delivery unit 231a described above.

When the second sliding body 237 of the delivery unit 231a protrudes toward the main unit 2, it is connected to the drug preparation section 80 of the main unit 2 below the drug accommodating section 237d provided in the second sliding body 237. The sub-collection hopper 87 has arrived. Therefore, when the shutter 255 of the delivery unit 231a existing on the main unit 2 side is opened in the state shown in FIG. 25A, the drug stored in the drug storage unit 237d is discharged to the drug preparation unit 80 of the main unit 2. be able to. On the other hand, when the second sliding body 237 of the delivery unit 231b protrudes from the subunit 3 side, the drug accommodating portion 237d arrives directly under the sub hopper 135 provided in the subunit 3. Therefore, when the drug is discharged from the sub-drug standby unit 130 in this state, the drug is charged into the drug accommodating unit 237d.

Subsequently, the operation of the drug dispensing system 1 adopting the transfer device 210 will be described focusing on the procedure for transferring the drug by the transfer device 210. In the drug dispensing system 1, similarly to the above embodiment, the drug dispensed from the main storage unit 20 and the hand-spraying unit 23 according to the prescription is provided in the drug preparation unit 80 of the compartment forming body 81. One packet is paid out to each section 81a.

When the drug to be prescribed is on the subunit 3 side, one packet of the drug is dispensed from each cassette 32 of the subunit 120. The drug discharged from the sub storage unit 120 is stored in the sub drug standby unit 130. On the other hand, in the transfer device 210, the delivery units 231a and 231b are in the extended state. As a result, the drug accommodating portion 237d provided in the second sliding body 237 of one of the delivery units 231a and 231b (in the state shown in FIG. 25A, the delivery unit 231b) has reached the lower part of the sub hopper 135. Will be. In this state, when the drug is discharged from the sub drug waiting unit 130, one packet of the drug discharged from the sub storage unit 120 is contained in the drug accommodating unit 237d.

When the drug is charged into the drug accommodating portion 237d, the delivery units 231a and 231b are brought into a contracted state as shown in FIG. 25 (b). After that, the swivel drive gear 226 provided on the base portion 222 of the transfer device 210 operates, and the delivery units 231a and 231b swivel 180 degrees around the swivel shaft 234. After that, the delivery units 231a and 231b are brought into the side extension state. As a result, the delivery unit 231b that received the drug on the subunit 3 side protrudes toward the main unit 2, and the drug accommodating unit 237d arrives on the sub-collection hopper 87 of the main unit 2. Further, regarding the other drug delivery unit 231a, the second sliding body 237 is in a state of protruding below the sub hopper 135, and is in a state of being able to accept the next one packet of drug.

When the delivery units 231b and 231a are extended on the main unit 2 and subunit 3 sides as described above, the shutter 255 provided on the drug storage unit 237d on the delivery unit 231b side is opened, and the subunit 3 side opens. The received drug is dispensed to each section 81a of the section forming body 81 provided in the drug preparation unit 80. On the other hand, the next one packet of medicine is charged from the sub-drug standby unit 130 into the medicine storage unit 237d on the delivery unit 231a side.

When the transfer device 210 is adopted in the drug dispensing system 1, the transfer units 231a and 231b are sequentially brought into the extended state and swiveled in the contracted state as described above, thereby paying out on the subunit 3 side.
