[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-56221 Summary of the Invention [Problem to be solved by the invention]

[0005] In a medicine packaging device such as that disclosed in Patent Document 1, there has been a demand for effectively shortening the time required to complete packaging.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to shorten the operation time for measuring out medicines.

[0007] The problem to be solved by the present invention is as described above. Next, the means for solving this problem and the effects thereof will be explained.

[0008] According to an aspect of the present invention, there is provided a medicine packaging device having the following configuration: The medicine packaging device includes a plurality of first containers, a second container, a first medicine supply unit, A measuring section; The device includes a second medicine supply unit and a packaging unit. The first containers store medicines by type. The medicines are supplied from the first containers to the second containers. The first medicine supply unit supplies one dose of medicine from each of the multiple first containers to the second container. The measuring unit is capable of detecting the weight of the medicine supplied from the first container to the second container. The second medicine supply unit supplies all of the medicine contained in the second container, and the packaging unit packages the medicine supplied by the second medicine supply unit into a single dose. The first medicine supply unit measures the medicine from the first container while measuring it with the measuring unit and supplies it to the second container.

[0009] This allows the medicines from multiple first containers to be packaged together in a single dose, using the second container as a unit. By measuring out the medicines from multiple first containers in parallel, the work time can be reduced. The amount of drug packaged can be accurate for each dose and for each delivery from each first container using a measuring unit.

[0010] In the medicine packaging device, it is preferable that the first medicine supplying section sequentially supplies one dose of medicine from each of the plurality of first containers to the second container.

[0011] This allows, for example, multiple types of medicine to be measured out and supplied to the second container, and packaged as a single dose. By carrying out the measuring out of multiple first containers like an assembly line, work efficiency can be improved.

[0014] In the above-mentioned drug packaging device, if the weighing value detected by the weighing unit exceeds one dose as a result of supplying the drug from the first container to the second container, it is preferable that the packaging unit skips packaging the drug in the second container.

[0015] This prevents the packaging of more medicine than is prescribed for a single dose.

[0016] In the above-mentioned drug packaging device, it is preferable to have an output unit that outputs at least one of the weight value of one dose measured by the measuring unit and the weight value of the total dose, which is the sum of the weight values ​​of the one dose, for each type of drug.

[0017] This allows the user to easily check the amount of medicine actually packaged.

[0018] In the above-mentioned medicine packaging device, it is preferable that the output unit outputs at least one of an indication value for one dose and an indication value for the total dose, which is the sum of the indication values ​​for the single doses, for each type of medicine.

[0019] This allows the user to easily compare the amount of medicine actually packaged with the indicated value. [Brief explanation of the drawings]

[Figure 5] 10A and 10B are schematic diagrams illustrating another example of the operation of the medicine packaging device. DETAILED DESCRIPTION OF THE INVENTION

[0021] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic diagram showing a medicine dispensing and packaging device 1 according to one embodiment of the present invention.

[0022] A medicine dispensing and packaging device (medicine packaging device) 1 shown in Figure 1 is installed in a pharmacy or a hospital. The medicine dispensing and packaging device 1 weighs and packages one or more medicines. The medicine dispensing and packaging performed by the medicine dispensing and packaging device 1 is performed based on prescription data input by an operator or prescription data received from an external source.

[0023] Measuring out a medicine means taking out only the required amount of medicine contained in a medicine container. In this embodiment, measuring out is performed by weighing the medicine to be supplied from the medicine container. The medicine packaging device 1 of this embodiment measures out powder medicine (powder, fine granules, or granular medicine) as the medicine. The medicine packaging device 1 packages the measured powder medicine. However, the medicine packaging device 1 may also be configured to be able to package tablets in addition to powder medicine.

[0024] The medicine packaging device 1 can store a plurality of medicine containers (first containers) 5 containing medicines. The medicine packaging device 1 can use the powder medicine in the medicine container 5 to perform a dispensing process of packaging the powder medicine for each dose.

[0025] The drug packaging device 1 includes a drug container storage section 11, a drug container transport section 15, a drug feeder (first drug supply section) 21, a measuring container transport section 31, a drug removal section (second drug supply section) 41, a packaging section 51, and a control device (control section) 95.

[0026] The medicine container storage unit 11 can store a plurality of medicine containers 5. The medicine container storage unit 11 includes a rotating member 12 and a medicine container arrangement unit 13.

[0027] The rotating member 12 is a substantially cylindrical member that is provided in an upright position and can rotate about a vertical axis by the driving force of a motor.

[0028] A plurality of drug container placement sections 13 are arranged side by side on the outer periphery of rotating member 12. A drug container 5 can be placed in each drug container placement section 13. Drug container placement section 13 can be, for example, a mounting plate capable of storing drug containers 5. Drug container placement section 13 rotates integrally with rotating member 12 as rotating member 12 rotates.

[0029] The drug container 5 is configured, for example, as a known drug cassette. Although not shown, the drug container 5 is formed with an outlet for discharging and supplying the drug outside the container. The drug containers 5 store drugs by type. In other words, different types of drugs are stored in different drug containers 5. In principle, drugs of the same type are stored in one drug container 5, but they may also be stored in multiple drug containers 5.

[0030] The drug container storage unit 11 is not limited to a configuration including a cylindrical rotating member 12. For example, the drug container storage unit 11 can be configured to include a storage shelf in which drug container arrangement units 13 are arranged in a matrix in the vertical and horizontal directions.

[0031] The medicine container transport unit 15 transports the medicine containers 5 between the medicine container storage unit 11 and the medicine feeder 21. The configuration of the medicine container transport unit 15 is arbitrary, and it can be configured as a transport robot, for example.

[0032] The drug container transport unit 15 can take out a drug container 5 from one of the drug container arrangement units 13 of the drug container storage unit 11, and transport it to and attach it to any one of three drug feeders 21 described below. The drug container transport unit 15 can remove a drug container 5 from the drug feeder 21, and transport it back to one of the drug container arrangement units 13.

[0033] Three drug feeders 21 are arranged side by side along measuring container transport path 34 that transports drugs. Measuring container transport path 34 is a circular transport path for measuring containers 33 in measuring container transport section 31, and will be described in detail below. A drug container 5 can be detachably attached to each drug feeder 21. Drug feeder 21 can measure the drug inside a drug container 5 set in that drug feeder 21 and deposit it into a measuring container 33 transported along measuring container transport path 34.

[0034] Each drug feeder 21 includes a vibration device 22 and a measuring unit 23.

[0035] Vibration device 22 vibrates medicine container 5 set in medicine feeder 21. When medicine container 5 set in medicine feeder 21 vibrates while the discharge outlet of medicine container 5 is open, the powder medicine in medicine container 5 is shaken out. The powder medicine that comes out from the discharge outlet falls into measuring container 33 located directly below the discharge outlet.

[0036] The weighing unit 23 can measure the weight of the weighing container 33, including the weight of the medicine contained in the weighing container 33. The weighing unit 23 is located below the weighing container transport path 34. The weighing unit 23 is configured as an electronic balance using a weight sensor such as a load cell, for example.

[0037] When medicine falls from the upper medicine container 5 while measuring container 33 is placed on measuring unit 23, the measured value detected by measuring unit 23 increases by the weight of the medicine. When the weight of the increased amount reaches one dose, medicine feeder 21 completes measuring the medicine.

[0038] The measuring container transport section 31 includes a rotary table (holding table, circulating transport member) 32 and four measuring containers (second containers) 33. The measuring containers 33 can also be called weighing containers.

[0039] The four measuring containers 33 are transported by the measuring container transport unit 31 so as to pass below the vibration device 22 that constitutes the medicine feeder 21 and above the measuring unit 23. Each measuring container 33 functions as a container for receiving medicine dispensed from the medicine container 5. The medicine contained in one measuring container 33 corresponds to one dose.

[0040] Each measuring container 33 is configured as a container that is open at the top. The bottom of each measuring container 33 can be switched between a closed state and a state that is open downward. In other words, an openable and closable valve mechanism is provided at the bottom of the measuring container 33. In this embodiment, an opening and closing plate is provided at the bottom of the measuring container 33, and the bottom is opened by rotating the opening and closing plate downward. However, the configuration in which the measuring container 33 is opened to discharge the medicine inside is optional.

[0041] The bottom of the measuring container 33 is normally closed, so that the medicine can be held inside. The bottom of the measuring container 33 can be opened by the medicine removal unit 41, which will be described later.

[0042] The four measuring containers 33 are supported by a circularly formed turntable 32. The turntable 32 is supported by the medicine packaging device 1 so as to be rotatable about a vertical axis. In a plan view, the rotation axis of the turntable 32 is located at the center of the circular turntable 32.

[0043] The turntable 32 can be rotated by the driving force of a motor. This allows the medicine placed in the measuring container 33 to be transported in the circumferential direction of the turntable 32. The turntable 32 can be raised and lowered by the driving force of a motor. This allows switching between a state in which the measuring container 33 is lifted by the turntable 32 and separated upward from the measuring unit 23, and a state in which the lifting is released and the measuring container 33 is placed on the measuring unit 23. The turntable 32 can also be driven by an actuator other than a motor, for example, a fluid pressure cylinder.

[0044] Although not shown, four holding portions (open portions) are formed on the outer periphery of the turntable 32. Each holding portion supports a measuring container 33. The holding portions can be configured as, for example, through-holes that penetrate the turntable 32 in the thickness direction, or as notches that open radially outward.

[0045] Each weighing container 33 is provided so as to be movable up and down relative to the turntable 32. A flange-like protrusion is formed on the side of the weighing container 33, and when the weighing container 33 is supported by the turntable 32, this protrusion is positioned above the turntable 32. When the turntable 32 is raised, the turntable 32 lifts the weighing container 33 via the protrusion, creating a gap between the underside of the weighing container 33 and the weighing unit 23. This allows the turntable 32 to rotate without dragging the weighing container 33 relative to the weighing unit 23. When the turntable 32 is lowered, the bottom of the weighing container 33 comes into contact with the weighing unit 23, thereby canceling the lifting. This allows the weighing unit 23 to properly detect the weight of the weighing container 33. The mechanism for switching between lifting and releasing the weighing container 33 can also be achieved by something other than a protrusion.

[0046] The four weighing containers 33 can be moved up and down independently of one another relative to the rotary table 32. Therefore, the weight of each weighing container 33 can be accurately obtained by the three weighing units 23.

[0047] Hereinafter, the path along which the measuring containers 33 and the medicines held inside the measuring containers 33 move as the turntable 32 rotates may be referred to as the measuring container transport path 34. The measuring container transport path 34 is formed in a loop shape. The three medicine feeders 21 are all arranged side by side along the measuring container transport path 34. The three medicine feeders 21 are arranged above three of the four locations to which the respective measuring containers 33 are selectively transported.

[0048] The drug removal unit 41 is provided midway along the measuring container transport path 34. The drug removal unit 41 is disposed downstream of the feeding position where the drugs are fed from the three drug feeders 21 into the measuring container 33 in the transport direction of the measuring container 33 caused by the rotation of the turntable 32 (in other words, the drug transport direction).

[0049] The drug removal unit 41 is equipped with a mechanism for opening the opening / closing plate at the bottom of the measuring container 33. In this embodiment, the drug removal unit 41 is equipped with an opening arm and an actuator (not shown). The opening / closing plate of the measuring container 33 is biased in the closing direction by an elastic member such as a spring. As a result, the opening / closing plate of the measuring container 33 is normally in a closed state. The opening arm of the drug removal unit 41 is driven by the actuator, contacts the opening / closing plate of the measuring container 33, and pushes it downward, opening the opening / closing plate. As a result, the drug contained in the measuring container 33 falls downward under its own weight.

[0050] 1 is drawn as an exploded view for convenience of illustration, but in reality, as shown in Fig. 2, the four measuring containers 33 are arranged at positions that divide the circular turntable 32 into four equal parts in the circumferential direction. In other words, the four measuring containers 33 are arranged so as to divide the outer periphery of the turntable 32 into 90° intervals.

[0051] Corresponding to the arrangement of the measuring containers 33, the three drug feeders 21 and one drug removal unit 41 are arranged at 90° intervals in the circumferential direction on the looped measuring container transport path 34 along which the measuring containers 33 are transported. The three drug feeders 21 are arranged side by side at 90° intervals, and the drug removal unit 41 is arranged at a position 90° downstream of the most downstream drug feeder 21.

[0052] Therefore, when one of the four measuring containers 33 is in a position corresponding to one of the three drug feeders 21, the other two measuring containers 33 are in positions corresponding to the remaining two drug feeders 21, and the remaining measuring container 33 is in a position corresponding to the drug take-out unit 41. By rotating the turntable 32 by 90° from this state, the rotation phases of all four measuring containers 33 change. Therefore, the drug feeders 21 and drug take-out units 41 corresponding to each measuring container 33 are selectively changed.

[0053] Hereinafter, in order to identify each of the three drug feeders 21, the drug feeder 21 located most upstream in the conveyance direction of the measuring container 33 will be referred to as the first drug feeder, and the drug feeders 21 located further downstream will be referred to as the second drug feeder, the third drug feeder, and so on.

[0054] Focus on one measuring container 33 depicted on the left side in Figure 2. In the state of Figure 2, this measuring container 33 corresponds to the first drug feeder 21. When the turntable 32 rotates 90° from this state, the measuring container 33 moves to a position corresponding to the second drug feeder 21. When the turntable 32 rotates another 90°, the measuring container 33 moves to a position corresponding to the third drug feeder 21. When the turntable 32 rotates another 90°, the measuring container 33 moves to a position corresponding to the drug removal unit 41. When the turntable 32 rotates another 90°, the measuring container 33 returns to the position corresponding to the first drug feeder 21.

[0055] In this way, the measuring container 33 is cyclically transported by driving the rotary table 32. The same is true for the other measuring containers 33. The measuring containers 33 are transported intermittently at predetermined angular intervals (every 90° in this embodiment).

[0056] Packaging unit 51 can package medicines. As shown in FIG. 1 , packaging unit 51 includes hopper 52. Hopper 52 is disposed directly below the position of measuring container 33 corresponding to medicine removal unit 41. When medicine removal unit 41 drops one dose of medicine into hopper 52, packaging unit 51 packages the medicine in packaging paper (packaging body) 54. The packaged medicine is supplied to the outside of medicine packaging device 1.

[0057] Packaging unit 51 includes printing unit 53. Printing unit 53 can print various information on packaging paper 54. The configuration of printing unit 53 is arbitrary, but it can be, for example, a known ink ribbon printer.

[0058] The medicine packing device 1 includes an interface unit 91. The interface unit 91 realizes a user interface function. The interface unit 91 can include, for example, a display device that displays the status of the dispensing process and information input by the user, and an operation device that allows the user to input instructions.

[0059] The control device 95 is a computer equipped with a CPU, ROM, RAM, etc. The ROM stores a control program for operating the medicine packaging device. The operations of the medicine container storage unit 11, the medicine container transport unit 15, the medicine feeder 21, the turntable 32, the medicine removal unit 41, the packaging unit 51, and the interface unit 91 are controlled by the control device 95.

[0060] The control device 95 can control each part of the medicine packaging device 1 (specifically, the medicine container storage part 11, the medicine container transport part 15, the medicine feeder 21, the measuring container transport part 31, the medicine removal part 41, the packaging part 51, etc.) based on the dispensing data. The control device 95 is configured as a known computer and includes an arithmetic unit such as a CPU, a storage device such as a flash memory or a hard disk, and an input / output part for communicating with the outside. The storage device stores various programs and setting values. The arithmetic unit reads out the various programs, etc. from the storage device and controls the operation of each part of the medicine packaging device 1 based on the detection values ​​of sensors provided in each part of the medicine packaging device 1 and the various setting values, etc. stored in the storage device.

[0061] A medicine container 5 containing a different medicine can be set in each of the three medicine feeders 21. Here, it is assumed that a medicine container 5 containing a medicine named "Drug A" is set in the first medicine feeder 21, a medicine container 5 containing a medicine named "Drug B" is set in the second medicine feeder 21, and a medicine container 5 containing a medicine named "Drug C" is set in the third medicine feeder 21.

[0062] Focus on the single measuring container 33 depicted on the far left in FIG. 3(a). As shown in FIGS. 3(a) to 3(c), as this measuring container 33 is transported from the first, second, and third drug feeders 21 to the drug loading positions, a single dose of drug A, drug B, and drug C is extracted and sequentially loaded into this measuring container 33. Thereafter, as shown in FIG. 3(d), the measuring container 33 is transported to the drug extraction unit 41, where the single doses of drug A, drug B, and drug C contained in the measuring container 33 are discharged into the packaging unit 51. At this time, each of the subsequent measuring containers 33 receives a drug from the first to third drug feeders 21. In this way, the weighing of each of the three types of drug and the discharge of the single dose are performed simultaneously in parallel.

[0063] In this way, according to this embodiment, multiple types of medicine can be packaged together in single doses using measuring container 33 as a unit. The configuration of this embodiment is particularly advantageous in that it allows for quick packaging of a small number of medicines, compared to configurations that use distribution trays like conventional medicine packaging devices.

[0064] Furthermore, in this embodiment, the weights of drugs A, B, and C can be acquired for each packet by the weighing unit 23 while they are packaged. The measured weight of one dose is output by an appropriate method. Possible output methods include printing on journal paper using a printing device, displaying on a display device provided in the interface unit 91, or printing on packaging paper 54 by the printing unit 53. In other words, the printing device, display device, and printing unit 53 described above can correspond to an output unit for outputting the measured weight of the drugs.

[0065] Consider a case where the prescribed amounts per dose given to the medicine packaging device 1 are 0.5 g of medicine A, 1.0 g of medicine B, and 0.3 g of medicine C. These prescribed amounts are included in the aforementioned dispensing data. In this embodiment, for example, for the first package, the amounts are 0.50 g of medicine A, 0.99 g of medicine B, and 0.31 g of medicine C, and for the second package, the amounts are 0.51 g of medicine A, 1.00 g of medicine B, and 0.31 g of medicine C, and so on, are output. The output format is arbitrary, and can be, for example, output as text or a table.

[0066] The output may include an indication amount in addition to the measurement value, in which case the user can easily compare the measurement value and the indication amount.

[0067] Instead of or in addition to the measured value of the weight of one dose, the measured value of the total dose can also be output. For example, if the drug packaging device 1 is instructed to package a seven-day supply of drugs to be taken twice a day, the measured values ​​of the total doses will be output, for example, 7.02 g of drug A, 14.05 g of drug B, and 4.17 g of drug C. In this case, the output format is also optional. To allow the user to easily compare the measured values, the output content may include the indicated amount of the total dose in addition to the measured values ​​of the total dose.

[0068] As shown in Figure 3(b), Figure 3(c), or Figure 3(d), when a certain measuring container 33 receives a supply of drug B from the second drug feeder 21, the measuring container 33 immediately succeeding this measuring container 33 simultaneously receives a supply of drug A from the first drug feeder 21. Also, as shown in Figure 3(c) or Figure 3(d), when a certain measuring container 33 receives a supply of drug C from the third drug feeder 21, the measuring container 33 immediately succeeding this measuring container 33 simultaneously receives a supply of drug B from the second drug feeder 21, and the measuring container 33 immediately succeeding this measuring container 33 simultaneously receives a supply of drug A from the first drug feeder 21. In this way, multiple drugs can be measured out simultaneously in parallel, which can significantly improve work efficiency.

[0069] Next, a modified medicine dispensing and packaging device will be described with reference to Fig. 4. In the description of this modified example, the same or similar components as those in the above-described embodiment are denoted by the same reference numerals in the drawings, and their description may be omitted.

[0070] In the modified medicine packaging device shown in Figure 4, the measuring container transport section 31 has five measuring containers 33. The measuring containers 33 are arranged so as to divide the circumference of the turntable 32 at 72° intervals. In this modified example, the transport of the five measuring containers 33 is performed intermittently at 72° intervals.

[0071] In the configuration of FIG. 3, the medicine extracting section 41, the disposal section 61, and the three medicine feeders 21 are arranged so as to divide the loop-shaped measuring container transport path 34 every 72° in the circumferential direction.

[0072] The three drug feeders 21 are arranged side by side, with a phase difference of 72° between them. A drug removal unit 41 is arranged 72° downstream of the third drug feeder 21 in the conveying direction of the measuring container 33. A waste unit 61 and a waste tank 62 are arranged 72° downstream of the drug removal unit 41.

[0073] Like the drug removal unit 41, the disposal unit 61 includes an opening arm and an actuator (not shown). When the opening arm is driven, the opening and closing plate of the measuring container 33 rotates downward, causing the drug contained in the measuring container 33 to fall downward. The waste tank 62 is disposed directly below the measuring container 33 at a position corresponding to the disposal unit 61. The drug that falls from the measuring container 33 is stored in the waste tank 62.

[0074] Some powder medicines tend to form clumps in medicine container 5. If medicine A, medicine B, or medicine C in medicine container 5 is discharged in clumps from any of three medicine feeders 21, the amount of medicine dispensed into measuring container 33 may exceed one dose.

[0075] The measuring unit 23 can detect that the amount of medicine placed in the measuring container 33 exceeds one dose. When such a measuring container 33 occurs, even if the measuring container 33 is transported to the medicine removal unit 41, the control device 95 controls the operation of the medicine removal unit 41 and the packaging operation in the packaging unit 51 to be skipped. When a measuring container 33 containing an amount of medicine A, medicine B, or medicine C that exceeds one dose is transported to the disposal unit 61, the opening and closing plate is opened, thereby discharging the medicine inside into the waste tank 62. When a measuring container 33 fails to measure out medicine during a series of operations for dispensing multiple doses, it is preferable that additional dispensing operations be automatically performed in succession to make up for the amount discarded.

[0076] If the amount of any of drug A, drug B, and drug C does not exceed one dose, the bottom plate of measuring container 33 is opened in drug removal section 41, and the drugs inside are supplied to packaging section 51. When empty measuring container 33 is transported to disposal section 61, the bottom plate may be opened by disposal section 61, or the operation of disposal section 61 may be skipped.

[0077] A cleaning device for cleaning the measuring container 33 may be provided. Although the cleaning device is not shown, it can be arranged, for example, near the disposal unit 61 so that the measuring container 33 located at the disposal unit 61 can be cleaned. Alternatively, a cleaning device may be provided instead of the disposal unit 61. The cleaning device cleans the measuring container 33 that has passed through the location of the drug removal unit 41. Cleaning is performed before the measuring container 33 is transported to the first drug feeder 21. The cleaning device can be configured, for example, by a suction nozzle or a cleaning brush, but is not limited to these.

[0078] As described above, the medicine dispensing and packaging device 1 of this embodiment includes a plurality of medicine containers 5, a measuring container 33, a plurality of medicine feeders 21, a medicine removal unit 41, and a packaging unit 51. The medicine containers 5 contain medicines by type. Medicines are supplied from the measuring containers 33. Each of the plurality of medicine feeders 21 supplies one dose of medicine from the attached medicine container 5 to the measuring container 33. The medicine removal unit 41 supplies all of the medicine contained in the measuring container 33. The packaging unit 51 packages the medicines supplied by the medicine removal unit 41 as one dose.

[0079] This allows multiple types of medicines to be packaged together in a single dose using measuring container 33 as a unit. Multiple medicine feeders 21 can perform measuring operations in parallel, thereby reducing the operation time.

[0080] In the medicine dispensing and packaging device 1 of the present embodiment, each medicine feeder 21 measures out one dose of medicine from each of the plurality of medicine containers 5 and supplies the medicine to measuring container 33 in sequence.

[0081] This allows a plurality of types of medicine to be measured out and supplied to measuring containers 33 in an assembly line manner using a plurality of medicine feeders 21, thereby improving work efficiency.

[0082] The medicine packaging device 1 of this embodiment includes a weighing unit 23 that can detect the weight of the medicine supplied from the medicine container 5 to the measuring container 33. Each medicine feeder 21 measures the medicine from the medicine container 5 while measuring it with the weighing unit 23, and supplies it to the measuring container 33.

[0083] This allows the amount of medicine to be packaged accurately for each dose and for each supply from each medicine container 5 using the measuring unit 23.

[0084] In the modified drug packaging device shown in Figure 4, if the measurement value detected by the measuring unit 23 exceeds one dose as a result of supplying drug from drug container 5 to measuring container 33, the packaging unit 51 skips packaging the drug in measuring container 33.

[0085] This prevents the packaging of more medicine than is prescribed for a single dose.

[0086] In the drug packaging device 1 of this embodiment, the weight value of one dose measured by the measuring unit 23 and the weight value of the total dose, which is the sum of the weight values ​​of the one dose, can be output for each type of drug to, for example, a display device provided in the interface unit 91.

[0087] This allows the user, a pharmacist, to easily check the amount of medicine packaged.

[0088] In the medicine dispensing and packaging device 1 of this embodiment, the display device outputs, for each type of medicine, an indication value for one dose and an indication value for the total dose, which is the sum of the indication values ​​for the single doses.

[0089] This allows the user, a pharmacist, to easily compare the amount of medicine actually packaged with the indicated value.

[0090] The preferred embodiment and modifications of the present invention have been described above, but the above configurations can be modified, for example, as follows. Each modification may be made alone, or multiple modifications may be made in any combination.

[0091] In the configuration of FIG. 2, the first, second, and third drug feeders 21 may all be equipped with the same drug containers 5. In this case, the turntable 32 is rotated so that the three empty measuring containers 33 are positioned corresponding to the first, second, and third drug feeders 21, respectively. Then, as shown in FIG. 5(a), the three drug feeders 21 simultaneously measure out a single dose. Then, as shown in FIGS. 5(b) to 5(d), the three measuring containers 33 are transported one by one to the drug removal unit 41, where they are supplied to the packaging unit 51 for packaging. When all measuring containers 33 are empty, the system returns to FIG. 5(a), and the same operation is repeated. Even when packaging only one type of drug, parallel weighing by the three drug feeders 21 can shorten the operation time. In this way, it may not be necessary to transport the measuring containers 33 sequentially to the three drug feeders 21 to measure out the drug.

[0092] The configuration for transporting the measuring container 33 along the loop-shaped circulation path is not limited to the turntable 32. For example, the measuring container 33 can be transported using a circulation belt conveyor. Furthermore, the shape of the measuring container transport path 34 is not limited to a circular shape, and can be formed into, for example, a rectangular shape.

[0093] The measuring container transport path 34 may be formed in an end shape instead of a loop shape, in which case the plurality of measuring containers 33 are configured to move back and forth along the measuring container transport path.

[0094] The measuring unit 23 may measure the medicine container 5 instead of the measuring container 33, thereby measuring the medicine. In this configuration, the measuring unit 23 is disposed on the vibration device 22 side, so a mechanism for raising and lowering the turntable 32 can be omitted. Also, in this configuration, it is not necessary to support the measuring container 33 on the turntable 32 so that it can move up and down. Therefore, for example, multiple measuring containers 33 can be fixed to the turntable 32 or configured integrally with the turntable 32.

[0095] The structure for holding the bottom of the measuring container 33 closed can be realized by a structure other than a spring, for example, a magnet.

[0096] The number of drug feeders 21 is not limited to three, but may be two or four or more. Similarly, the number of measuring containers 33 in the measuring container transport section 31 may be changed as appropriate.

[0097] Drug feeder 21 is not limited to a configuration including vibration device 22. For example, when a transporter that transports the powder medicine contained in drug container 5 toward the discharge port is provided inside drug container 5, drug feeder 21 may be configured to drive the transporter and discharge the powder medicine contained in drug container 5 from the discharge port.
