FIG. 3 is a schematic diagram of the intermediate conveyance section viewed from above. FIG. 3 is a schematic diagram illustrating an example of the operation of the medicine packaging device. FIG. 7 is a schematic diagram of a modified medicine packaging device, viewed from above. FIG. 7 is a schematic diagram illustrating another example of the operation of the medicine packaging device.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing a drug packaging device 1 according to an embodiment of the present invention.

A drug packaging device (drug packaging device) 1 shown in FIG. 1 is installed in a pharmacy or a hospital. The drug packaging device 1 weighs and packages one or more drugs. Measuring and packaging of medicines performed by the medicine packaging device 1 is performed based on prescription data input by an operator or prescription data received from an external source.

Weighing out a drug refers to taking out the required amount of a drug contained in a drug container. In this embodiment, weighing is performed by measuring the medicine to be supplied from the medicine container. The drug packaging device 1 of this embodiment weighs out a powder (powdery, fine granular, or granular drug) as a drug. The drug packaging device 1 packages measured powders. However, the medicine packaging device 1 may be configured to be capable of packaging tablets in addition to powders.

The drug packaging device 1 can store a plurality of drug containers (first containers) 5 containing drugs. The drug packaging device 1 can use the powder in the drug container 5 to perform a dispensing process of packaging the powder into individual doses.

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 weighed container transport section 31, and a drug take-out section (second drug supply section). ) 41, a packaging section 51, and a control device (control section) 95.

The drug container storage section 11 can store a plurality of drug containers 5. The drug container storage section 11 includes a rotating member 12 and a drug container placement section 13 .

The rotating member 12 is a substantially cylindrical member and is provided in an upright position. The rotating member 12 can be rotated about an axis in the vertical direction by the driving force of the motor.

A plurality of medicine container arrangement parts 13 are arranged in a row on the outer circumference of the rotating member 12 . A drug container 5 can be placed in each drug container placement section 13 . The drug container arrangement section 13 can be, for example, a mounting plate that can accommodate the drug container 5. The drug container placement section 13 rotates integrally with the rotation of the rotation member 12 as the rotation member 12 rotates.

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 to the outside of the container. The drug container 5 stores drugs by type. In other words, different types of drugs are housed in different drug containers 5. In principle, drugs of the same type are stored in one drug container 5, but they may be stored in a plurality of drug containers 5.

The medicine container storage section 11 is not limited to a configuration including the cylindrical rotating member 12. The drug container storage section 11 can be configured to include, for example, a storage shelf in which the drug container placement section 13 is arranged in a matrix in a vertical direction and a horizontal direction.

The drug container transport section 15 transports the drug container 5 between the drug container storage section 11 and the drug feeder 21 . Although the configuration of the drug container transport section 15 is arbitrary, it can be configured as a transport robot, for example.

The drug container transport section 15 can take out the drug container 5 from one of the drug container placement sections 13 of the drug container storage section 11, and transport it to any one of the three drug feeders 21 to be described later and attach it thereto. . The drug container transport section 15 can remove the drug container 5 from the drug feeder 21 and transport it back to one of the drug container placement sections 13.

Three medicine feeders 21 are arranged side by side along a weighing container transport path 34 for transporting medicine. The weighing container transport route 34 is a cyclical transport route for the weighing containers 33 in the weighing container transport section 31, and details will be described later. A drug container 5 can be removably attached to each drug feeder 21. The medicine feeder 21 can weigh out the medicine inside the medicine container 5 set in the medicine feeder 21 and put it into the weighed container 33 that is transported along the weighed container transport path 34.

Each medicine feeder 21 includes a vibration device 22 and a measuring section 23.

The vibration device 22 vibrates the medicine container 5 set in the medicine feeder 21. When the medicine container 5 set in the medicine feeder 21 vibrates with the discharge port of the medicine container 5 open, the powder in the medicine container 5 is shaken out. The powder discharged from the discharge port falls into a weighing container 33 located directly below the discharge port.

The measuring 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 section 23 is located below the weighing container conveyance path 34. The weighing section 23 is configured as an electronic balance using a weight sensor such as a load cell, for example.

When the medicine falls from the medicine container 5 above with the measuring container 33 placed on the measuring part 23, the measured value detected by the measuring part 23 increases by the weight thereof. When the increased weight reaches one dose, the drug feeder 21 completes measuring out the drug.

The weighing container conveying section 31 includes a rotary table (holding table, circulation conveyance member) 32 and four weighing containers (second containers) 33. The weighing container 33 can also be referred to as a weighing container.

The four weighing containers 33 are transported by the weighing container conveying section 31 so as to pass below the vibrating device 22 constituting the drug feeder 21 and above the measuring section 23 . Each weighing container 33 functions as a container for receiving the medicine introduced from the medicine container 5. The medicine contained in one measuring container 33 corresponds to one dose.

Each weighing container 33 is configured as a container with an open top. The bottom of each weighing container 33 can be switched between a closed state and a downwardly open state. In other words, the bottom of the weighing container 33 is provided with a valve mechanism that can be opened and closed. In this embodiment, an opening/closing plate is provided at the bottom of the weighing container 33, and the bottom is opened by rotating the opening/closing plate downward. However, the configuration for opening the weighing container 33 to discharge the medicine inside is arbitrary.

The bottom of the weighing container 33 is normally closed so that the drug can be held inside. The bottom of the weighing container 33 can be opened by a medicine removal section 41, which will be described later.

The four weighing containers 33 are supported by a circular rotary table 32. The rotary table 32 is supported by the medicine packaging device 1 so as to be rotatable about an axis in the vertical direction. In plan view, the rotation axis of the rotary table 32 is located at the center of the circular rotary table 32.

The rotary table 32 can be rotated by the driving force of a motor. Thereby, the medicine put into the weighing container 33 can be conveyed in the circumferential direction of the rotary table 32. The rotary table 32 can be moved up and down by the driving force of a motor. This allows switching between a state in which the weighing container 33 is lifted by the rotary table 32 and separated upward from the measuring section 23, and a state in which the lifting is released and the weighing container 33 is placed on the measuring section 23. Can be done. The rotary table 32 can also be driven by an actuator other than a motor, such as a hydraulic cylinder.

Although not shown, four holding parts (open parts) are formed on the outer circumference of the rotary table 32. A weighing container 33 is supported by each holding section. The holding portion can be configured, for example, as a through hole penetrating the rotary table 32 in the thickness direction, or a notch that opens outward in the radial direction.

Each weighing container 33 is provided to be movable up and down with respect to the rotary table 32. A flange-like projection is formed on the side of the weighing container 33, and when the weighing container 33 is supported by the rotary table 32, this projection is located above the rotary table 32. When the rotary table 32 is raised, the rotary table 32 lifts the weighing container 33 via the protrusion, so a gap is formed between the lower surface of the weighing container 33 and the weighing part 23. Therefore, the rotary table 32 can be rotated without dragging the weighing container 33 with respect to the measuring section 23. When the rotary table 32 is lowered, the bottom of the weighing container 33 comes into contact with the measuring section 23, thereby eliminating lifting. Therefore, the weight of the weighing container 33 can be appropriately detected by the measuring section 23. The configuration for switching between lifting and releasing the weighing container 33 can also be realized by other than the protrusion.

The four weighing containers 33 can be moved up and down relative to the rotary table 32 independently of each other. Therefore, the three weighing sections 23 can accurately obtain the weight of each weighing container 33.

Hereinafter, the route along which the weighing container 33 and the drug held inside the weighing container 33 move as the rotary table 32 rotates may be referred to as a weighing container conveyance path 34. The measuring container transport path 34 is formed in a loop shape. All three medicine feeders 21 are arranged side by side along the weighing container conveyance path 34. The three drug feeders 21 are arranged above three of the four locations where the respective weighing containers 33 are selectively transported.

The drug removal section 41 is provided in the middle of the weighing container conveyance path 34. The medicine take-out unit 41 is configured to move the measuring container 33 in the transport direction (in other words, the medicine transport direction) by the rotation of the rotary table 32 with respect to the input position where medicines are put into the weighing container 33 from the three medicine feeders 21. It is located on the downstream side.

The drug extraction section 41 includes a mechanism that opens an opening/closing plate at the bottom of the weighing container 33. In this embodiment, the drug extraction section 41 includes an open arm and an actuator (not shown). The opening/closing plate of the weighing 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 weighing container 33 is normally closed. The opening arm of the drug take-out section 41 is driven by an actuator to contact the opening/closing plate of the weighing container 33 and push it downward to open the opening/closing plate. As a result, the medicine contained in the weighing container 33 falls downward under its own weight.

Although FIG. 1 is shown as a developed view for convenience of expression, in reality, as shown in FIG. placed in each location. In other words, the four weighing containers 33 are arranged so as to divide the outer circumference of the rotary table 32 every 90°.

Corresponding to the arrangement of the weighing containers 33, the three drug feeders 21 and one drug take-out section 41 are arranged at intervals of 90° in the circumferential direction in the loop-shaped weighing container conveyance path 34 along which the weighing containers 33 are conveyed. They are placed at intervals. Three drug feeders 21 are arranged in line at 90° intervals, and a drug take-out portion 41 is arranged at a position 90° downstream of the most downstream drug feeder 21.

Therefore, when one of the four measuring containers 33 is in a position corresponding to any of the three drug feeders 21, the other two measuring containers 33 are in positions corresponding to the remaining two drug feeders 21, In addition, the remaining one measuring container 33 is located at a position corresponding to the drug removal section 41. By rotating the rotary table 32 by 90 degrees from this state, the rotational phases of all four weighing containers 33 change. Therefore, the medicine feeder 21 and medicine take-out section 41 corresponding to each weighing container 33 are selectively changed.

Hereinafter, in order to identify each of the three drug feeders 21, the drug feeder 21 located furthest upstream in the conveying direction of the weighing container 33 will be referred to as the first, and as it goes downstream, it will be referred to as the second and third. .

Attention is drawn to one weighing container 33 depicted on the left side in FIG. This weighing container 33 corresponds to the first drug feeder 21 in the state shown in FIG. When the rotary table 32 rotates 90 degrees from this state, the weighing container 33 moves to a position corresponding to the second drug feeder 21. When the rotary table 32 further rotates by 90 degrees, the weighing container 33 moves to a position corresponding to the third medicine feeder 21. When the rotary table 32 is further rotated by 90 degrees, the weighing container 33 moves to a position corresponding to the medicine extraction section 41. When the rotary table 32 further rotates by 90 degrees, the weighing container 33 returns to the position corresponding to the first drug feeder 21.

In this way, the weighing container 33 is cyclically conveyed by the drive of the rotary table 32. The same applies to the other weighing containers 33. The weighing container 33 is transported intermittently at every predetermined angle (in this embodiment, every 90 degrees).

The packaging section 51 can package medicine. As shown in FIG. 1, the packaging section 51 includes a hopper 52. The hopper 52 is disposed directly below the position of the weighing container 33 corresponding to the medicine removal section 41. When the drug take-out section 41 drops one dose of the drug into the hopper 52, the packaging section 51 wraps the drug in a packaging paper (wrapping body) 54. The packaged medicine is supplied to the outside of the medicine packaging device 1.

The packaging section 51 includes a printing section 53. The printing unit 53 can print various information on the packaging paper 54. Although the configuration of this printing section 53 is arbitrary, it can be, for example, a known ink ribbon type printer.

The drug packaging device 1 includes an interface section 91. The interface section 91 implements a user interface function. The interface unit 91 can be configured to include, for example, a display device that displays the status of dispensing processing, user input information, and the like, and an operating device that allows the user to input instructions.

The control device 95 is a computer including a CPU, ROM, RAM, and the like. A control program for operating the medicine packaging device is stored in the ROM. The operations of the drug container storage section 11 , the drug container transport section 15 , the drug feeder 21 , the rotary table 32 , the drug takeout section 41 , the packaging section 51 , and the interface section 91 are controlled by a control device 95 .

The control device 95 controls 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, and the medicine take-out part) based on the dispensing data. 41, packaging section 51, etc.). 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 unit for communicating with the outside. The storage device stores various programs and setting values. The arithmetic device reads various programs etc. from the storage device and operates the medicine packaging device 1 based on the detection values of the sensors provided in each part of the medicine packaging device 1 and various setting values stored in the storage device. Controls the operation of each part.

In the three drug feeders 21, drug containers 5 each containing a different drug can be set. Here, a drug container 5 containing a drug named "Drug A" is set in the first drug feeder 21, and a drug container 5 containing a drug named "Drug B" is set in the second drug feeder 21. Consider a case where a medicine container 5 containing a medicine named "drug C" is set in the third medicine feeder 21.

Attention is paid to one weighing container 33 drawn on the leftmost side in FIG. 3(a). As shown in FIGS. 3(a) to 3(c), this weighing container 33 is moved to the input position where medicines are input from the first medicine feeder 21, the second medicine feeder 21, and the third medicine feeder 21. As the medicine is being transported, medicine A, medicine B, and medicine C are taken out by weight for one dose and are sequentially put into the weighing container 33. Thereafter, as shown in FIG. 3(d), the weighing container 33 is transported to the location of the medicine take-out section 41, and one dose of medicine A, medicine B, and medicine C stored in the weighing container 33 is taken out. It is discharged to the packaging section 51. At this time, each of the measuring containers 33 on the subsequent side receives the medicine from the first to third medicine feeders 21. In this way, the measurement of each of the three types of drugs and the discharge of one dose of the drug are performed simultaneously.

In this way, according to the present embodiment, a plurality of types of medicines can be packaged together into one dose using the measuring container 33 as a unit. The configuration of this embodiment is particularly preferable in that it can quickly package a small number of drugs compared to a configuration that uses a dispensing tray like a conventional drug packaging device.

Further, in this embodiment, the weights of medicine A, medicine B, and medicine C can be obtained for each package by the weighing section 23 while dividing the medicines into individual packages. The measured value of the weight of one dose is output by an appropriate method. Possible output methods include, for example, printing on journal paper using a printing device, displaying on a display device included in the interface section 91, or printing on packet paper 54 in the printing section 53. That is, the above-described printing device, display device, and printing unit 53 may correspond to an output unit for outputting the measured value of the medicine.

Consider a case where the instructions given to the drug packaging device 1 for one dose are 0.5 g for drug A, 1.0 g for drug B, and 0.3 g for drug C. This instruction amount is included in the aforementioned dispensing data. In this embodiment, for example, the first package contains 0.50 g of drug A, 0.99 g of drug B, and 0.31 g of drug C, and the second package contains 0.51 g of drug A and 0.51 g of drug B. 1.00g, drug C is 0.31g, etc. is output. The output format is arbitrary; for example, it can be output as text or as a table.

The output content may include an instruction amount in addition to the measured value. In this case, the user can easily compare the measured value and the instruction amount.

Instead of or in addition to the measured value of the weight of one dose, the measured value of the entire dose can also be output. For example, if an instruction is given to the drug packaging device 1 to package 7 days' worth of drugs to be taken twice a day, the weight values for all doses are, for example, 7.02 g of drug A, 7.02 g of drug A, 7.02 g of drug A, It is output that B weighs 14.05g and drug C weighs 4.17g. In this case as well, the output format is arbitrary. In order to facilitate comparison by the user, the output may include the instructions for the entire dose in addition to the measured values for the entire dose.

As shown in FIG. 3(b), FIG. 3(c), or FIG. 3(d), when a certain measuring container 33 receives medicine B from the second medicine feeder 21, at the same time, this measuring container 33 The weighing container 33 that is one subsequent to the container 33 receives the medicine A from the first medicine feeder 21 . Further, as shown in FIG. 3(c) or FIG. 3(d), when a certain weighing container 33 receives the medicine C from the third medicine feeder 21, at the same time, one metering container 33 receives the medicine C from the third medicine feeder 21. The measuring container 33 on the succeeding side receives the supply of medicine B from the second medicine feeder 21, and the measuring container 33 on the one succeeding side receives the supply of medicine A from the first medicine feeder 21. . In this way, a plurality of drugs can be weighed out simultaneously, so work efficiency can be greatly improved.

Next, a modified medicine packaging device will be described with reference to FIG. 4. In the description of this modification, members that are the same as or similar to those of the above-described embodiment are given the same reference numerals in the drawings, and the description may be omitted.

In the modified medicine packaging device shown in FIG. 4, the weighing container conveying section 31 includes five weighing containers 33. The weighing containers 33 are arranged so as to divide the outer circumference of the rotary table 32 into every 72 degrees. In this modification, the five weighing containers 33 are transported intermittently every 72 degrees.

In the configuration of FIG. 3, the medicine take-out part 41, the waste part 61, and the three medicine feeders 21 are arranged so as to divide the loop-shaped weighing container conveyance path 34 into every 72 degrees in the circumferential direction.

The three drug feeders 21 are arranged side by side with their phases differing by 72 degrees. A medicine take-out section 41 is arranged 72° downstream of the third medicine feeder 21 in the conveying direction of the measuring container 33 . A waste portion 61 and a waste tank 62 are arranged 72 degrees downstream from the drug extraction portion 41 .

The disposal section 61, like the drug removal section 41, includes an open arm and an actuator (not shown). By driving the open arm and rotating the opening/closing plate of the weighing container 33 downward, the drug contained in the weighing container 33 can be dropped downward. The waste tank 62 is arranged directly below the weighing container 33 at a position corresponding to the waste section 61. The medicine that has fallen from the measuring container 33 is stored in the waste tank 62.

Some powders tend to form lumps in the medicine container 5. If any of the three drug feeders 21 discharges drug A, drug B, or drug C in the drug container 5 in the form of a lump, the amount of drug fed into the measuring container 33 exceeds one dose. Sometimes I end up doing it.

The measuring unit 23 can detect that the amount of medicine put into the weighing container 33 exceeds one dose. When such a weighing container 33 occurs, the control device 95 skips the operation of the medicine takeout section 41 and the packaging operation in the packaging section 51 even if the weighing container 33 is transported to the medicine takeout section 41. control to do so. When the weighing container 33 contains more medicine A, medicine B, or medicine C than one dose, the opening/closing plate is opened when the container 33 is transported to the disposal section 61. The drug is discharged into waste tank 62. In a series of operations for dispensing multiple doses, if a measuring container 33 fails to measure out the medicine, it is preferable that an additional dispensing operation is automatically and continuously performed to make up for the wasted amount. .

If none of the drugs A, B, and C exceed the amount for one dose, the bottom plate of the weighing container 33 is opened at the drug take-out section 41, and the drug inside is supplied to the packaging section 51. . When the empty measuring container 33 is transported to the disposal section 61, the bottom plate may be opened by the disposal section 61, or the operation of the disposal section 61 may be skipped.

A cleaning device for cleaning the weighing container 33 may be provided. Although the cleaning device is not shown, it can be placed near the waste section 61, for example, so that the weighing container 33 located at the waste section 61 can be cleaned. Furthermore, a cleaning device may be provided instead of the waste section 61. The cleaning device cleans the weighing container 33 that has passed through the location where the drug removal section 41 is located. Cleaning is performed before the weighing container 33 is conveyed to the first drug feeder 21. The cleaning device may include, for example, a suction nozzle or a cleaning brush, but is not limited thereto.

As explained above, the drug packaging device 1 of the present embodiment includes a plurality of drug containers 5, a weighing container 33, a plurality of drug feeders 21, a drug take-out section 41, and a packaging section 51. Be prepared. The drug container 5 stores drugs by type. A medicine is supplied from the medicine container 5 to the measuring container 33 . Each of the plurality of drug feeders 21 measures out one dose of drug from the attached drug container 5 and supplies it to the container 33 . The medicine take-out section 41 supplies all the medicine contained in the weighing container 33. The packaging unit 51 packages the medicine supplied by the medicine extraction unit 41 as one dose.

Thereby, a plurality of types of drugs can be packaged together into one dose using the weighing container 33 as a unit. Since the plurality of medicine feeders 21 can perform measuring operations in parallel, the working time can be shortened.

In the medicine packaging device 1 of this embodiment, each medicine feeder 21 measures one dose of medicine from each of the plurality of medicine containers 5 and sequentially supplies the medicine to the measuring container 33 .

Thereby, work efficiency can be improved by measuring out and supplying a plurality of types of medicines to the weighing container 33 in an assembly line operation using the plurality of medicine feeders 21.

The drug packaging device 1 of this embodiment includes a weighing section 23 that can detect the weight of the drug supplied from the drug container 5 to the measuring container 33. Each medicine feeder 21 measures the medicine from the medicine container 5 while being measured by the measuring section 23 and supplies it to the measuring container 33 .

Thereby, the amount of medicine to be packaged can be made accurate for each dose and for each supply from each medicine container 5 using the measuring section 23.

In the modified drug packaging device shown in FIG. 4, when the measured value detected by the measuring section 23 exceeds one dose as a result of supplying the drug from the drug container 5 to the weighing container 33, the packaging section 51 Packaging of the medicine in the container 33 is skipped.

This can prevent packaging of a drug in an amount that exceeds the amount determined for one dose.

In the drug packaging device 1 of this embodiment, the weight value for one dose measured by the measuring unit 23 and the weight value for all doses, which is the sum of the weight values for the one dose, are determined for each type of drug. , for example, can be output to a display device included in the interface section 91.

Thereby, the pharmacist who is the user can easily confirm the amount of the packaged medicine.

In the drug packaging device 1 of the present embodiment, the display device outputs an instruction value for one dose and an instruction value for all doses, which is the sum of the instruction values for one dose, for each type of drug. do.

Thereby, the pharmacist who is the user can easily compare the amount of the drug actually packaged with the indicated value.

Although preferred embodiments and modifications of the present invention have been described above, the above configuration can be modified as follows, for example. A single change may be made, or a plurality of changes may be made in any combination.

In the configuration of FIG. 2, the first, second, and third drug feeders 21 may all be equipped with drug containers 5 containing the same drug. In this case, after rotating the rotary table 32 so that the three empty weighing containers 33 are at the positions corresponding to the first, second, and third drug feeders 21, respectively, as shown in FIG. As shown in , three drug feeders 21 measure out one dose at the same time. Thereafter, as shown in FIGS. 5(b) to 5(d), the three weighing containers 33 are sequentially conveyed one by one to the medicine take-out section 41, and the medicine is supplied to the packaging section 51 for packaging. . When all the weighing containers 33 have discharged the medicine and become empty, the process returns to FIG. 5(a) and the same operation is repeated. Even when packaging only one type of medicine, the working time can be shortened by measuring the three medicine feeders 21 in parallel. In this way, there are cases where it is not necessary to sequentially transport the measuring container 33 to the three drug feeders 21 in order to measure out the drug.

The configuration for conveying the weighing container 33 along the loop-shaped circulation path is not limited to the rotary table 32. For example, weighing containers 33 can be transported using a circulating belt conveyor. Further, the shape of the weighing container conveyance path 34 is not limited to a circular shape, but may be formed into a rectangular shape, for example.

The weighing container conveyance path 34 can be formed into an end shape instead of a loop shape. In this case, the plurality of weighing containers 33 are configured to reciprocate along the weighing conveyance path.

The measuring unit 23 may weigh the medicine container 5 instead of the weighing container 33 to measure the medicine. In this configuration, since the measuring section 23 is arranged on the vibrating device 22 side, a mechanism for raising and lowering the rotary table 32 can be omitted. Further, with this configuration, there is no need to support the weighing container 33 on the rotary table 32 so that it can be moved up and down. Therefore, for example, the plurality of measuring containers 33 can be fixed to the rotary table 32 or configured integrally with the rotary table 32.

The arrangement for holding the bottom of the weighing container 33 in a closed state can be realized by means of a different arrangement than a spring, for example by a magnet.

The number of drug feeders 21 is not limited to three, but can be two or four or more. Similarly, the number of weighing containers 33 in the weighing container transport section 31 can also be changed as appropriate.

The medicine feeder 21 is not limited to a configuration including the vibration device 22. For example, when a transport body is provided in the medicine container 5 for transporting the powder contained in the medicine container 5 toward the discharge port, the medicine feeder 21 is configured to drive the transport body, and the medicine contained in the medicine container 5 is The powder may be discharged from the discharge port.
