Description

Medicine dispensing device

Technical Field

The present invention relates to a medicine dispensing device for supporting dispensing operations in a hospital pharmacy or the like, and more particularly, to a medicine dispensing device that stores various kinds of medicines separately in a plurality of cassettes in advance and automatically dispenses the medicines as needed.

Background

Japanese patent laying-open No. 2012 and 139249 (patent document 1) discloses a conventional medicine dispensing apparatus in which medicines contained in cylindrical containers such as ampoules are stored in a magazine in a row, and after the medicines are discharged from a medicine discharge unit, the medicines are transferred by a transfer and input device and input into a transport tray. In the conventional medicine dispensing apparatus, the transfer loading device closes the lower surface of the transfer container when receiving the discharged medicine, and loads the medicine into the transfer container from the upper surface. The medicine to be handled by the medicine dispensing apparatus is a so-called round medicine such as an injection medicine contained in a cylindrical container such as an ampoule. Infusion bottles and the like also belong to the above-mentioned medicines if they are put into cylindrical containers. In the conventional medicine dispensing apparatus, when a medicine is loaded from the transfer container to the transport tray, the transfer container is lowered, the lower surface of the transfer container is inserted into the internal space of the transport tray, and then the lower surface of the transfer container is opened. The transmission mechanism is provided with a transmission part for supporting on a transmission path of the transmission mechanism, and when the transfer container is prevented from descending, the transmission of the driving force or movement for descending the transfer container is cut off. According to the conventional medicine dispensing apparatus, a transfer container that receives the medicine discharged from the storage cassette and transfers the medicine to the transport tray is received on an open upper surface thereof and is loaded on an open lower surface thereof. Then, the lowered transfer container is further lowered to allow the lower surface to enter the internal space of the transport tray, and then the lower surface of the transfer container is opened to be loaded. Thus, a medicine dispensing device can be realized: the cylindrical container can be reliably loaded with the medicine into the tray for transportation when the tray for transportation is shallow, and can be reliably loaded when the tray for transportation is deep. In addition, in the conventional medicine dispensing apparatus, even when the amount of the medicine to be dispensed is large or the medicine to be dispensed is accidentally raised, the medicine is not damaged by the impact of the collision because the transfer container is prevented from descending when the end portion of the transfer container abuts against the medicine in the tray to be dispensed. In this medicine dispensing device, while the transfer and loading device receives the medicine from the medicine discharge unit, the medicine cannot be loaded into the transport tray. Therefore, in the medicine dispensing apparatus disclosed in japanese patent No. 5564868 (patent document 2) and the like, the transfer and input device is divided into a transfer mechanism and an input mechanism, and the transfer and input are performed separately.

Problem to be solved by utility model

However, in the assembly structure similar to the conventional medicine dispensing apparatus, when the transfer and loading device is maintained and stored in the case of the medicine dispensing apparatus, the transfer and loading device must be entirely or partially removed to perform state confirmation (confirmation of failure in operation, release of medicine clogging in the storage section, and the like) and repair (including total replacement and partial replacement). Therefore, there is a problem that it takes time for an operator to perform work and maintenance in an environment where space is limited such as in a case of the medicine dispensing apparatus.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a medicine dispensing device, it can carry out the transfer and the input of medicine respectively to easily transfer the maintenance that drops into the device.

Means for solving the problems

The drug dispensing device to which the present invention is directed is provided with at least one unit row for storing drugs so that the drugs can be discharged, a transfer and input device for transferring the discharged drugs to a transport tray and inputting the transferred drugs to the transport tray, and a tray transport device. At least one of the unit columns is formed by arranging a plurality of unit rows, each of which is formed by arranging a plurality of medicine discharge units in a horizontal direction, in a vertical direction perpendicular to the horizontal direction, and each of the medicine discharge units is formed by arranging a storage cassette for storing the medicines contained in the cylindrical containers and a discharge mechanism for discharging the medicines contained in the cylindrical containers from the storage cassette. The transfer and input device moves in the horizontal direction along one unit row, moves in the vertical direction along the unit row, receives one or more discharged medicines discharged from the medicine discharge unit, and inputs the discharged medicines into the transfer tray. The tray conveying device is disposed below the transfer loading device, and conveys the conveying tray in a conveying direction orthogonal to the horizontal direction and the vertical direction.

In the present invention, the transfer and input device is constituted by a transfer mechanism and an input mechanism. The transfer mechanism includes a storage unit having a discharge function, and moves the storage unit in a horizontal direction and in an up-down direction, and the storage unit receives and temporarily stores one or more medicines discharged from the plurality of medicine discharge units, and discharges the stored one or more medicines downward in response to a command. The loading mechanism includes a hopper unit having a hopper portion disposed below the transfer mechanism and having an upper opening for receiving the plurality of medicines discharged from the storage portion, and an opening/closing door provided on a bottom wall side of the hopper portion and opened when the plurality of medicines are loaded into the transport tray, and a hopper moving mechanism for moving the hopper unit in an up-down direction between a first position for receiving the plurality of medicines from the storage portion and a second position for discharging the plurality of discharged medicines to the transport tray. In the present invention, the storage unit and the input mechanism are supported by the first sliding mechanism and the second sliding mechanism, respectively, so as to be slidable in a horizontal direction in which the plurality of unit rows are arranged, and the first sliding mechanism and the second sliding mechanism are configured to: the storage section and the loading mechanism can be pulled out to the front side in the horizontal direction of the tray conveying device during maintenance.

According to the present invention, since the storage section and the input mechanism can be pulled out to the front side in the horizontal direction, maintenance (status confirmation and repair) is easy.

Further, the tray conveying device may be supported by the third slide mechanism to be slidable in a horizontal direction in which the plurality of unit rows are aligned. In this case, the third slide mechanism is configured to: the tray conveying device can be pulled out to the front side in the horizontal direction during maintenance. The tray transport device can be pulled out forward, and maintenance is easier.

Further, it is preferable that the cable bundle connecting the transfer mechanism and the control device including the power supply is housed in the cable tray. Thus, the cable bundle is protected by the cable bracket, and therefore, even if the storage section and the input mechanism are pulled out forward, the occurrence of disconnection can be prevented.

Further, it is preferable that an access window is provided in a side wall portion of the storage portion located on the front side in the horizontal direction. This makes it easy to bring the medicine stored in the storage section into a dischargeable posture.

Further, the hopper mechanism and the hopper moving mechanism are preferably configured such that: when the shutter door interferes with the discharged medicine already put into the tray for conveyance while the hopper mechanism is moved from the first position to the second position, the lowering of the hopper mechanism is stopped, the shutter door is opened, and the hopper mechanism is returned to the first position. Thus, the medicine put into the conveyance tray first is not damaged by the medicine put later.

Preferably, the first unit row and the second unit row are arranged in two rows in the conveying direction, and when the transfer mechanism is configured such that the storage section moves in the vertical direction between the first unit row and the second unit row, the storage section includes a first divided storage section that receives the medicine from the medicine discharge unit of the first unit row and a second divided storage section that receives the medicine from the medicine discharge unit of the second unit row. Preferably, the upper opening of the hopper portion has a size that enables the medicine to be received simultaneously from both the first divided storage portion and the second divided storage portion. With this configuration, the medicine can be received by one hopper section for two unit rows. The medicine can be put into the transport tray from one hopper.

Preferably, the hopper mechanism is provided with a buffer plate which is held swingably by a central shaft extending in a horizontal direction in an upper opening portion, and the buffer plate swings when colliding with the medicines discharged from the first divided storage portion and the second divided storage portion when the hopper portion is located at the first position, thereby suppressing the momentum of the medicines. Therefore, the medicines can be prevented from colliding with each other and being damaged when the medicines are thrown into the hopper part.

Further, preferably, the buffer plate stays at the first position even if the hopper portion moves from the first position to the second position, and is located outside the hopper portion when the hopper portion is located at the second position. Thus, the buffer plate does not become an obstacle to the medicine input when the medicine is input to the transport tray.

The hopper unit may further include: a pair of fixed inclined walls having a pair of fixed inclined surfaces inclined to be close to each other downward from a pair of edges of the upper opening portion opposed to each other in the conveyance direction; a pair of movable inclined walls including a pair of movable inclined surfaces, the pair of movable inclined surfaces being continuous with the pair of fixed inclined surfaces in a state where one end of each of the pair of movable inclined walls is rotatably attached to a distal end of the pair of fixed inclined walls and the other end of each of the pair of movable inclined walls is in contact with the other end of the pair of fixed inclined walls; and a pair of guide walls that provide a pair of guide surfaces, one end of each of the pair of guide walls being rotatably attached to a distal end of each of the pair of movable inclined walls, wherein the pair of guide walls are positioned outside the pair of movable inclined walls when the hopper is at the first position, and the pair of guide walls are suspended below the pair of movable inclined walls when the hopper is at the second position, and the pair of guide surfaces are continuous with the pair of movable inclined surfaces. In this case, the pair of movable inclined walls and the pair of guide walls are configured such that: when the hopper portion moves from the second position to the first position, the other ends of the pair of movable inclined walls are in contact with each other, and the pair of guide walls are located outside the pair of movable inclined walls. Thus, the medicine can be reliably loaded into the conveying tray through the pair of movable inclined walls and the pair of guide walls.

The structure of the present embodiment will be described with reference to fig. 1 (a) and (B) to fig. 3 (a) and (B). In particular, as shown in fig. 3 (a) and (B), in the medicine dispensing device 1 of the present embodiment, the first unit row 5 and the second unit row 7, which house the cylindrical containers of the medicines 3 so as to be discharged, are arranged in two rows in the conveying direction X orthogonal to the horizontal direction Y and the vertical direction Z. Further, a transfer loading device 11 that transfers the discharged medicine 3 to the transfer tray 9 and loads the transfer tray 9 is provided between the first unit row 5 and the second unit row 7, and a tray transfer device 10 that transfers the medicine in the transfer direction X is provided below the transfer loading device 11.

The first unit row 5 and the second unit row 7 are configured by six first unit rows 57 and second unit rows 77 arranged in the vertical direction orthogonal to the horizontal direction, the first unit rows 57 and the second unit rows 77 are configured by three

medicine discharge units

55 and 75 arranged in the horizontal direction, and the

medicine discharge units

55 and 75 are configured by a storage cassette 51 and a storage cassette 71 in which cylindrical container-packed medicines 3 are stored in an aligned manner, and a discharge mechanism 53 and a discharge mechanism 73 (see fig. 14) which discharge cylindrical container-packed medicines 3 from the storage cassette 51 and the storage cassette 71.

The transfer loading device 11 moves in the horizontal direction Y along the first unit row 57 and the second unit row 77, moves in the vertical direction Z along the first unit row 5 and the second unit row 7, receives one or more medicines 3 discharged from the medicine discharge unit 55 and the medicine discharge unit 75, and loads the medicines into the transport tray 9. The transfer loading device 11 is composed of a transfer mechanism 13 and a loading mechanism 15. The transfer mechanism 13 includes a stock section moving mechanism 13A that moves the first and second divided

stock sections

17 and 19 in the vertical direction Z, a columnar rail 13B that serves as a guide rail when the stock section moving mechanism 13A moves in the vertical direction Z, and a horizontal moving mechanism 13C that moves the columnar rail 13B in the horizontal direction Y. The transfer mechanism 13 includes a storage unit 16(17, 19) having a discharge function and moves the storage unit in the horizontal direction and the vertical direction, and the storage unit 16(17, 19) receives and temporarily stores one or more medicines discharged from the plurality of

medicine discharge units

55 and 75 and discharges the stored one or more medicines downward in response to a command. The reservoir 16 includes a first separate reservoir 17 and a second separate reservoir 19, the first separate reservoir 17 receiving the medicine from the medicine discharge unit 55 of the first unit row 5, and the second separate reservoir 19 receiving the medicine 3 from the medicine discharge unit 75 of the second unit row 7. An access window W is provided in the side wall portions of the first and second divided

storage portions

17 and 19 located on the front side in the horizontal direction Y. In fig. 3 (a), the side wall portion of the first divided storage portion 17 is removed to show the internal mechanism, and therefore the access window W is not shown in the first divided storage portion 17. When the access window W is provided, the medicine stored in the first and second divided

storage portions

17 and 19 in the non-dischargeable posture can be easily discharged.

In the present embodiment, as shown in fig. 2 (a) and (B), the stock unit 16, the loading mechanism 15, and the tray conveying device 10 are supported by the first slide mechanism 12, the second slide mechanism 14, and the third slide mechanism 18, respectively, so as to be slidable in the horizontal direction Y in which a plurality of unit rows are aligned. The first slide mechanism 12 and the second slide mechanism 14 are configured to: the stock unit 16 and the loading mechanism 15 can be pulled out to the front side in the horizontal direction Y of the tray conveying device 10 in the stored state at the time of inspection. The third slide mechanism 18 is configured to: the tray conveying device 10 can be pulled out to the front side in the horizontal direction Y at the time of inspection.

The first slide mechanism 12 for pulling out the storage unit at the time of maintenance has two rails 12A, and the two rails 12A are attached to the storage unit moving mechanism 13A so as to be slidable in front of the columnar rail 13B in the horizontal direction Y. The two rails 12A are drawn out forward during maintenance, are stored on the back side during operation of the apparatus, are moved in the vertical direction by the storage section moving mechanism 13A, and are moved in the horizontal direction together with the columnar rail 13B by the horizontal moving mechanism 13C. By moving the reservoir 16 to the outside of the apparatus, the clogging of the medicine in the reservoir can be easily released.

The second slide mechanism 14 that pulls out the loading mechanism 15 to the front side in the horizontal direction Y at the time of inspection includes a plurality of rails 14A extending in the horizontal direction Y and arranged at intervals in the transport direction X as shown in fig. 2 (B), and a rack 14B that moves the rails 14A. The input mechanism 15 is fixed to the center of the stage 14B. Since the loading mechanism 15 is moved to the outside of the apparatus, clogging of the medicine in the loading mechanism 15 can be easily solved.

The third slide mechanism 18 for pulling out the tray conveying device 10 to the front side in the horizontal direction Y at the time of inspection includes a rail 18A extending in the horizontal direction Y and disposed at an interval in the conveying direction X as shown in fig. 2 (a) and (B), and a slide support mechanism (not shown) for slidably supporting the rail 18A. The input mechanism 15 is fixed to the center of the stage 14B. Since the loading mechanism 15 is moved to the outside of the apparatus, clogging of the medicine in the loading mechanism 15 can be easily solved. The tray conveyor 10 is pulled out forward, so that maintenance of the tray conveyor 10 is facilitated.

In the present embodiment, a cable harness connecting at least the transfer mechanism 13 and the control device including the power supply is housed in the cable tray. Thus, since the cable bundle is protected by the cable tray, even if at least the transfer mechanism 13 and the input mechanism 15 are pulled out forward, the occurrence of the disconnection can be prevented.

Fig. 14 sequentially shows the operation when the medicines 3 are loaded into the first divided storage section 17 from the storage cassette 51 of the medicine discharge unit 55 of the first unit row 5. When the first storage portion 17 reaches the front of the storage case 51 of the medicine discharge unit 55, the discharge mechanism 53 is opened, and one medicine 3 naturally falls down to the first storage portion 17 by gravity. The medicine 3 that has fallen naturally swings the swing door 17A, which is disposed in the first divided storage 17 and whose movable range is restricted, and enters the storage chamber 17B. After that, the swing door 17A returns to the original position. As a result, the medicine 3 is prevented from flying out of the storage chamber 17B. Further, by opening the opening/closing door 17C constituting the bottom wall of the storage chamber 17B, the medicine 3 entering the storage chamber 17B is discharged downward from the storage chamber 17B.

As shown in fig. 3 (a) and (B) and fig. 15, the loading mechanism 15 includes a hopper mechanism 27 having a hopper portion 23 disposed below the transfer mechanism 13 and having an upper opening portion 21 for receiving the plurality of medicines discharged from the first divided storage portion 17 and the second divided storage portion 19 of the storage portion 16, and a hopper mechanism 27 provided on the bottom wall side of the hopper portion 23 and having an opening/closing door 25 opened when the plurality of medicines 3 are loaded into the transport tray 9, and a hopper moving mechanism 29 for moving the hopper mechanism 27 in the vertical direction between a first position for receiving the plurality of medicines 3 from the first divided storage portion 17 and the second divided storage portion 19 and a second position for discharging the plurality of medicines 3 to the transport tray 9. The upper opening 21 of the hopper 23 has a size that allows the medicines to be received simultaneously from both the first separate storage section 17 and the second separate storage section 19. With this configuration, the medicines can be received by one hopper 23 for the two-row unit rows 5 and 7. The medicine can be put into the conveyance tray 9 from one hopper 23.

Further, a buffer plate 33 is disposed in the hopper mechanism 27, the buffer plate 33 is held by a central shaft 31 so as to be swingable, the central shaft 31 extends in the horizontal direction Y above the upper opening 21, and when the hopper portion 23 is located at a first position (positions shown in fig. 3 (a) and (B), fig. 15 (a), and fig. 16 (a) and (B)), the buffer plate 33 swings when colliding with the medicines 3 discharged from the first divided storage portion 17 and the second divided storage portion 19, and the momentum of the medicines 3 is suppressed. When such a buffer plate 33 is provided, as shown in fig. 17 (a) to (D), the opening and

closing doors

17C and 19C are opened, and thus, when the medicines 3 are input into the hopper portion 23, the medicines can be prevented from colliding with each other and being damaged.

Further, even if the hopper portion 23 moves from the first position to the second position (the positions shown in fig. 15C, 16C, and D) located below the first position, the buffer plate 33 stays at the first position, and when the hopper portion 23 is located at the second position, the buffer plate 33 is located outside the hopper portion 23. As a result, as shown in fig. 18 (a) to 18(D) and 19 (E) and (F), when the medicine 3 is loaded into the transport tray 9, the buffer plate 33 does not become an obstacle to the medicine loading.

As shown in fig. 18 (a) to (D) and fig. 19 (E) and (F), the hopper section 23 includes: a pair of fixed inclined walls 22A and 22B including a pair of fixed inclined surfaces FS1 and FS2, the pair of fixed inclined surfaces FS1 and FS2 being inclined so as to be adjacent to each other downward from a pair of edges 21A and 21B of the upper opening 21 that face each other in the conveying direction X; a pair of movable inclined walls 24A and 24B including a pair of movable inclined surfaces MS1 and MS2, the pair of movable inclined surfaces MS1 and MS2 continuing to the pair of fixed inclined surfaces FS1 and FS2 in a state where one end of each of the pair of movable inclined walls 24A and 24B is rotatably attached to the tip ends of the pair of fixed inclined walls 22A and 22B and the other end is in contact with each other; and a pair of guide walls 26A and 26B that provide a pair of guide surfaces GS1 and GS2, one ends of the guide walls 26A and 26B being rotatably attached to the ends of the pair of movable inclined walls 24A and 24B, the guide walls 26A and 26B being located outside the pair of movable inclined walls 24A and 24B when the hopper section 23 is at the first position, the guide walls 26A and 26B being suspended below the pair of movable inclined walls 24A and 24B when the hopper section is at the second position, and the guide surfaces GS1 and GS2 being continuous with the pair of movable inclined surfaces MS1 and MS 2. In the present embodiment, the opening/closing door 25 is configured by a pair of movable

inclined walls

24A and 24B and a pair of

guide walls

26A and 26B. In the present embodiment, the pair of movable

inclined walls

24A and 24B and the pair of

guide walls

26A and 26B are configured such that: when the hopper portion 23 moves from the second position to the first position, the other ends of the pair of movable

inclined walls

24A and 24B come into contact with each other, and the pair of

guide walls

26A and 26B are positioned outside the pair of movable

inclined walls

24A and 24B. Thus, the medicine 3 can be reliably loaded into the conveying tray 9 by the pair of movable

inclined walls

24A and 24B and the pair of

guide walls

26A and 26B. The hopper mechanism 27 and the hopper moving mechanism 29 are configured to: when the opening/closing door 25 interferes with the discharged medicine already put into the conveying tray 9 while the hopper mechanism 27 is moved from the first position (the position of fig. 18a and 16 a) to the second position (the position of fig. 18D and 16B), the lowering of the hopper mechanism 27 is stopped, the opening/closing door 25 is opened, and the hopper mechanism 27 is returned to the first position. Here, the state in which the opening/closing door 25 is opened means a state in which the opening/closing door 25 is continuously extended downward in a state in which the pair of movable

inclined walls

24A and 24B and the pair of

guide walls

26A and 26B are connected to each other in a process of returning the hopper mechanism 27 to the first position (see fig. 19 (E) and (F)). Thus, the medicine 3 can be reliably loaded into the transport tray 9 without flying out of the transport tray 9.

As shown in fig. 15 (a) to (C) and fig. 16 (a) to (D), the hopper moving mechanism 29 includes an engaging hook 29A, and the engaging hook 29A engages with an engaged portion 23A (fig. 15 (B) and fig. 16 (a) to (D)) provided on an end surface of the base portion 23A of the hopper portion 23 of the hopper mechanism 27. In fig. 15 (a) to (C) and fig. 16 (a) to (D), unnecessary parts are not shown in the description for clarity of the drawings. The engaging hook 29A moves in the vertical direction Z in a slot 28A, and the slot 28A is provided in a guide column 28 extending in the vertical direction Z. The hook portion 29A of the engaging hook 29A engages with the lower surface of the engaged portion 23a, and the hopper mechanism 27 is prevented from dropping. The engaging hook 29A moves in the vertical direction Z together with the slider 29C (fig. 16 (B) and (D)) of the linear electromagnetic actuator 29B. When the hopper moving mechanism 29 is used, if the opening/closing door 25 interferes with the medicine discharged from the transport tray 9 when the hopper mechanism 27 is moved from the first position (the position of fig. 16 a and 16B) to the second position (the position of fig. 16C and 16D), only the engaging hook 29A is lowered, and the hopper mechanism 27 is not lowered. This state can be detected by, for example, attaching a pressure sensor or the like to the engagement surface of the hook portion 29A of the engagement hook 29A in advance, and detecting the separation of the hook portion 29A from the engaged portion 23a based on the change in the resistance value. When this state is detected, the control unit, not shown, controls the linear electromagnetic actuator 29B so as to stop the lowering of the engaging hook 29A, to bring the opening/closing door 25 into the openable state, and to return the hopper mechanism 27 to the first position. Since the opening/closing door 25 is in the openable state, the opening/closing door 25 is in the open state and the pair of movable

inclined walls

24A and 24B and the pair of

guide walls

26A and 26B are continuously extended downward in a state of being connected to each other while the hopper mechanism 27 is returned to the first position. As a result, the medicine 3 entered into the hopper portion 23 is loaded into the conveying tray 9.

When the engaging hook 29A is further lifted, the pair of

guide walls

26A and 26B go around the outside of the pair of movable

inclined walls

24A and 24B, and the opening/closing door 25 is closed. The operation at this time is the same as the operations shown in fig. 19 (E) to (G). Further, a drive mechanism for performing an opening/closing operation of the opening/closing door 25 is installed in the base portion 23A of the hopper mechanism 27.

(action)

The following describes an outline of the operation of the present embodiment with reference to fig. 3, 17, 18, and 19. When the medicine 3 is loaded from the medicine discharge unit 55 to the transport tray 9 in response to a command from a control device, not shown, the transfer mechanism 13 of the transfer loading device 11 moves the first component storage section 17 to the position of the corresponding medicine discharge unit 55 as shown in fig. 1 ((a) of fig. 3 and (B) of fig. 3). Then, the medicine 3 is discharged from the medicine discharge unit 55 into the storage chamber 17B of the first divided storage 17 ((D) of fig. 3). Next, the transfer mechanism 13 moves to above the hopper portion 23 of the loading mechanism 15. The medicine 3 is loaded into the hopper portion 23 of the loading mechanism 15 from the storage chamber 17B of the first divided storage 17 of the transfer mechanism 13 ((F) to (I) of fig. 3 and (a) to (D) of fig. 17). Then, the transfer mechanism 13 is raised to a predetermined position to receive the next medicine 3. After the required number and types of medicines are all loaded into the hopper section 23 by repeating the above-described operations, the loading mechanism 15 moves the hopper section 23 from the first position (the position of fig. 16 a and 16B and the position of fig. 18 a) to the second position (the position of fig. 16C and 16D and 18D) by the operation of the hopper mechanism 27 as shown in fig. 18a to D and fig. 19E to H, and thereby the medicines 3 are loaded into the conveying tray 9. When the charging is completed, as shown in fig. 19 (E) to (H), the hopper section 23 is returned from the second position (the position of fig. 16 (C), fig. 16 (D), and fig. 18 (D)) to the first position (the position of fig. 16 (a), fig. 16 (B), and fig. 18 (a)) by the operation of the hopper mechanism 27. During this operation, the transfer mechanism 13 performs the next medicine 3 collecting operation. In order to load necessary medicines into the four storage spaces partitioned inside the transport tray 9, the tray transport device 10 intermittently transports the transport tray 9 in accordance with the vertical movement of the hopper portion 23 driven by the hopper mechanism 27.

When the medicine drops and the jam is cleared or the maintenance is performed, the power supply is suspended, and after the front panel is opened, at least one of the storage section 16 of the transfer mechanism 13, the loading mechanism 15, and the tray conveyor 10, which needs to be inspected, is pulled forward to perform necessary treatment. And returning the pulled-out member to the original position after the disposal. In the present embodiment, since all of the storage section 16, the loading mechanism 15, and the tray conveying device 10 of the transfer mechanism 13 can be pulled out forward, maintenance is very easy.

Industrial applicability

According to the present invention, since the transfer and the input of the medicine can be performed separately, and the storage section and the input mechanism can be pulled out to the front side in the horizontal direction, the medicine dispensing device which is easy to maintain and transfers the input device can be provided.
