  The medicine packaging device 203 includes a packaging hopper 220 and a packaging device 221 as shown in FIG.

Next, a procedure for packaging a powder using the powder packaging apparatus 200 will be described.
The operation of dispensing the powder is performed by a user such as a pharmacist (hereinafter simply referred to as a pharmacist) operating the powder dispensing and packaging device 200 according to a doctor's prescription. That is, the pharmacist checks the doctor's prescription and removes the medicine bottle containing the prescribed powder from a medicine shelf (not shown). Then, the total weight of the prescribed powdered medicine is weighed out using a balance such as a balance.
That is, it is a powdered medicine taken three times a day, and 1.0 g is prescribed at a time, and when medicine for 20 days is prescribed, (1.0 × 3 × 20 = 60) g Powder is removed. More specifically, the container is placed on a balance, tared, the powder is taken out of the medicine bottle using a medicine spoon, the powder is put into the container on the balance, and 60 g of the powder is weighed out.

Further, the powdered medicine that follows is dropped on the distribution dish 212 by a fixed amount per time. Finally, the last powder drops into the dispensing dish 212 and all the 60 grams of powder enters the groove 216.

On the other hand, since the distribution dish 212 is rotating at a predetermined speed, the powdered medicine falling from the trough 210 is evenly distributed in the grooves 216 of the distribution dish 212.
That is, the powder is gradually dropped on the distribution plate 212 by the powder feeder 206, and the distribution plate 212 is rotated at a constant speed, so that the powder is uniformly distributed in the grooves 216 of the distribution plate 212.

  When the drop of the powder on the distribution plate 212 is completed, the rotation of the distribution plate 212 is temporarily stopped. After that, the disk 217 of the scraping device 215 is dropped into the groove 216 of the distribution plate 212. After that, the distribution tray 212 is rotated by an angle corresponding to the number of distribution plates. Explaining in the previous example, since 60 grams of powder is packaged in 60 packets, the dispensing dish 212 is rotated by (60/360) degrees, and the powder is placed on the front side of the disk 217 by (60/360) degrees. Collect. Then, the disc 217 is rotated, and the powdered medicine of (60/360) degrees is scraped out of the dispensing dish 212 by the scraping plate 218 and is put into the hopper 220 for packaging. The powder dropped from the packaging hopper 220 is packaged by the packaging device 221.

The information of the prescription, the name of the pharmacist, and the type and amount of the weighed medicine are written into the RFID tag 22 of the manual medicine container 5a by the RFID reader / writer 134 of the medicine weighing device. That is, the RFID reader / writer 134 functions as an information writing unit.

Then, the manual medicine container 5a is moved manually or by using a robot, and the manual medicine container 5a is placed on the container vibration table 11 of the main device 2.
Here, an RFID reader 16 serving as a main body side information reading means is provided near the container vibration table 11, and the dispensing information is read into the main body device 2 by the RFID reader 16. Then, the read dispensing information is displayed on the touch panel 106 provided in the main body device 2. Therefore, the pharmacist can check the dispensing information displayed on the touch panel 106.

  In addition, when there is an item requiring some additional work or an operation different from the regular operation, or when there is a special caution in the dispensing information, the fact is displayed on the touch panel 106. The pharmacist examines the displayed contents, and can operate the touch panel 106 to instruct the main device 2 on work items and the like. That is, the touch panel 106 can be used to instruct additional work or change the work content.

The precautions to be displayed on the touch panel 106 include a case where the type and amount of the medicine described in the prescription are different from the type and amount of the medicine contained in the manual-type medicine container 5a. For example, in a case where a plurality of types of drugs are packaged in the same package, there are three types of drugs described in the prescription, but only two types are incorporated in the manual type drug container 5a. In some cases, as a work in the main unit 2, it is necessary to put the remaining medicine into the distribution dish 7.
Similarly, when a plurality of types of drugs are packed in the same package, there is a case where the drugs are put into the dispensing dish 7 from a plurality of manually-operated drug containers 5a. In such a case, The pharmacist operates the touch panel 106 to operate the main device 2 so as to perform an operation along the operation.
Further, although not directly related to the present invention, when the amount of medicine stored in the accommodating medicine container 4 to be distributed together is smaller than the prescribed amount, the support screen for the medicine filling operation is displayed on the screen of the touch panel 106 and the The filling operation may be performed.

  Further, in the case where the powdered medicine and the tablet are packed together, a predetermined operation is instructed from the touch panel 106. For example, when employing a main unit having a function of dispensing a solid medicine such as a tablet, or when employing a main unit having a "hand sowing function" for individually enclosing tablets and the like, the touch panel 106 is also used. A predetermined operation is instructed.

  Also, in the case where the medicine contained in the housed medicine container 4 adopted in the embodiment described later is packed, the pharmacist operates the touch panel 106 to cause the main unit 2 to execute necessary operations. Furthermore, the case where the medicine required for encapsulation is not contained in the accommodation type medicine container 4 or is in short supply, and the case where it is necessary to newly fill the accommodation type medicine container 4 with the medicine is also required. Then, the pharmacist operates the touch panel 106 to cause the main device 2 to execute necessary operations.

When the pharmacist's prescription inspection and predetermined addition instructions are completed, and the pharmacist operates the touch panel 106 and inputs a confirmation signal, the following packaging operation is started. Note that the confirmation signal is to touch a predetermined display portion of the touch panel 106, but the display of the confirmation is arbitrary, and for example, a display such as "confirmation" or "work start" can be considered. In short, the pharmacist creates an opportunity to start packaging on his own.
In the packaging operation, the distribution dish 7 is rotated, and at the same time, the container vibration table 11 is vibrated. As a result, the manual-type medicine container 5a on the container vibration table 11 vibrates, and the powdered medicine inside moves slowly to the medicine discharge unit 20 side, and finally falls from the medicine discharge unit 20 to the distribution plate 7. That is, in the present embodiment, the powdered medicine falls directly from the manually-operated medicine container 5a to the dispensing dish 7 without passing through a conventional trough.
When all of the powder has been dropped, the rotation of the distribution dish 7 is stopped. Thereafter, according to the dispensing information read by the RFID reader 16, the powdered medicine in the dispensing dish 7 is divided into a predetermined number, the medicine is scraped out by the scraping device 8, and the medicine is put into the medicine packaging device 6, and the medicine is packaged individually. Prescribed characters are printed on the bag.

The stored medicine information of the stored medicine identification information for identifying the stored medicine recorded in the medicine bottle is read from a medicine bottle or the like.
When the stored medicine read by the stored medicine information reading means corresponds to any of the prescription medicines read by the prescription information reading means, the control means selects the prescription medicine as a weighing target and weighs the prescription medicine. The target weighing screen is displayed on the display means.
Further, necessary information is written into the RFID tag 22 of the manually-operated medicine container 5a by the information writing means.

  Hereinafter, a schematic configuration of the medicine weighing device 3 will be described. As shown in FIG. 15, the medicine weighing device 3 includes a control unit 131, a balance unit 132, a touch panel 133, an RFID reader / writer 134, a data storage unit 135, a USB port 136, a barcode reader 32, a printer 140, and the like. In particular, at least the balance base 30, the control unit 131, the balance unit 132, and the touch panel 133 are integrally provided in the apparatus main body of the medicine weighing device 3.

The control unit 131 is a computer that includes a CPU, a ROM, a RAM (such as an EEPROM), and controls the medicine weighing device 3 in an integrated manner. The CPU is a processor that executes various arithmetic processes according to various programs.
The ROM is a nonvolatile memory in which a program executed by the CPU is stored in advance. The RAM is a volatile memory or a non-volatile memory used for developing various programs by the CPU and temporarily storing data in various arithmetic processes.

  The balance unit 132 is a weighing unit that includes the stainless steel balance platform 30 and weighs the medicine placed on the balance platform 30. Specifically, the balance unit 132 is a balance unit used in a conventionally well-known electronic balance including a balance circuit, a force coil, a current / voltage conversion circuit, an A / D conversion circuit, and the like. The weight of the medicine weighed by the balance unit 132 is input to the control unit 131 as digital data.

When weighing a medicine with the medicine weighing device 3, a pharmacist or the like places the medicine in the manual medicine container 5a after placing the manual medicine container 5a on the balance platform 30. As described above, the manual-type medicine container 5a is provided with the RFID tag 22 as a recording medium on which various information is read and written.
The RFID tag 22 is provided at a position where data can be read and written by the RFID reader / writer 134 when the manually-operated medicine container 5a is placed on the balance platform 30.
The balance unit 132 sets a value obtained by subtracting a preset weight of the manual-type medicine container 5a and the RFID tag 22 as a medicine weighing value.

  The touch panel 133 detects a display unit such as a liquid crystal panel or an organic EL panel that displays various screens and various information in accordance with a control instruction from the control unit 131, and detects operation of operation keys displayed on the display unit. A detection unit for inputting a signal to the control unit 131; That is, the touch panel 133 also serves as a display unit and an input unit in the medicine weighing device 3. Specifically, the control unit 131 causes the touch panel 133 to display the weighed value weighed by the balance unit 132.

The RFID reader / writer 134 records information on or reads information from an RFID tag or an RFID label using an RFID wireless communication technology.
The RFID reader / writer 134 is provided adjacent to the balance 30 and is used to read and write information from and to the RFID tag 22 when the manual-type medicine container 5 a is placed on the balance 30. . Of course, the RFID reader / writer 134 may be built in the medicine weighing device 3.

  The data storage unit 135 is a USB memory or other recording medium that stores a control program such as a medicine weighing program executed by the control unit 131 and various data such as a medicine master, and is detachable from the medicine weighing device 3. It is possible.

  The medicine weighing program is software that causes a computer such as the control unit 131 to execute each processing step of a medicine weighing process described later (see FIG. 18). The control unit 131 also includes an inspection program for inspecting whether or not the weighed value of the medicine is within a range of a normal dose (an appropriate amount to be taken once or once) set for each medicine. For this reason, the medicine weighing device 3 can perform both the weighing of the medicine and the inspection of the normal dose independently without using another information processing device such as a computer.

  The drug master contains the drug code, drug name, JAN code (or RSS), vial code, classification (dose form: powder, tablet, solution, topical drug, etc.), specific gravity, drug type (ordinary drug, poison, Drugs, powerful drugs, antipsychotics, remedies, etc.), compounding changes, excipients, precautions, regular doses (equivalent to appropriate dose information), simultaneous dosing prohibition information, etc. are included.

  The JAN code (RSS) is information corresponding to the stored medicine name recorded in a medicine bottle or the like supplied from a pharmaceutical manufacturer, and the JAN code is recorded (described) in a medicine bottle in a bar code. In addition, the medicine bottle code is information corresponding to the stored medicine name recorded in the medicine bottle when the medicine in the medicine box supplied from the pharmaceutical manufacturer is subdivided into medicine bottles. Is recorded by a bar code. The control unit 131 can obtain the name of the stored medicine corresponding to each barcode by referring to the medicine master.

By the way, in the present embodiment, a case where a medicine name is used as information for identifying a medicine will be described as an example. However, the present invention is not limited to this, and a medicine code or the like may be used.
The normal dose is an appropriate amount to be taken once a day or once predetermined for each drug. Simultaneous dose prohibition information is information about a drug that is prohibited from being taken at the same time, which is predetermined for each drug.

  The barcode reader 32 reads information from a one-dimensional barcode such as a JAN code or RSS and a two-dimensional code such as a QR code (registered trademark).

  In the medicine weighing device 3, the control unit 131 uses the barcode reader 32 to store information such as a prescription containing one or more prescription medicine names recorded (written) on the prescription on a QR code (registered trademark) recorded on the prescription. ) And read from a two-dimensional code. The prescription information includes prescription delivery date, patient ID, patient name, patient's date of birth, drug information (drug code, drug name, dose, dosage form information "for internal use such as tablets, powdered medicine, ointments, etc. Drug)), usage information (eg, three times a day after each meal), and the like.

  In the medicine weighing device 3, the control unit 131 uses the barcode reader 32 to record (describe) the stored medicine information including the stored medicine name recorded (described) in the medicine bottle with the barcode. From the JAN code or vial code. Here, the control unit 131 at the time of executing the reading process corresponds to a stored medicine information reading unit.

  The method of reading the prescription and the like information and the stored medicine information from the prescription and the like or the medicine bottle is not limited to the one using a barcode, but may be one using a character recognition technology or an image recognition technology.

  It is also conceivable that an information recording medium such as an RFID tag or an RFID label is provided in the medicine bottle, and the medicine storage information including the name of the medicine contained in the medicine bottle is recorded on the information recording medium.

Similarly, it is conceivable that an information recording medium such as an RFID tag or an RFID label is provided on the prescription, and information such as prescription including the prescription medicine name recorded on the prescription is recorded on the information recording medium.
Alternatively, prescription information may be input to a receipt computer or the like in advance, transmitted from the receipt computer or the like to the drug weighing device 3 via a LAN (wired / wireless), and received by the drug weighing device 3.

  The printer 140 prints out print data input from the control unit 131 via the USB port 136. Specifically, the printer 140 is used to print a result of weighing by the medicine weighing device 3 and the like.

Next, the function of the medicine dispensing apparatus 1 of the present embodiment will be described following an actual work procedure. The medicine dispensing apparatus 1 can execute fully automatic packaging using the accommodated medicine container 4 and manual packaging using the manual medicine container 5a.
The medicine dispensing apparatus 1 of the present embodiment is characterized in the latter manual packaging, and the manual packaging using the manual medicine container 5a will be described below.
The operation procedure of the manual packaging is roughly divided into a “drug weighing operation” and a “drug packaging operation”. The medicine weighing operation is an operation performed using the medicine weighing device 3, and the medicine packaging operation is an operation performed using the main device 2.
The main device 2 has two types of drug containers. In the present embodiment, a manual drug container 5a is used.
Hereinafter, the "drug weighing operation" will be described with reference to the flowchart of FIG. The flowchart shows an example of a procedure of a medicine weighing process executed by the control unit 131 in the medicine weighing device 3 according to a medicine weighing program.

The medicine weighing process is a process executed by the control unit 131 when the power of the medicine weighing device is turned on. Here, the prescription includes the date of delivery of the prescription, patient ID, patient name, date of birth of the patient, and drug information (drug code, drug name, dose, dosage form information, such as internal medicine such as tablets and powdered medicines, and external use of ointments and the like). A description will be given of an example in which dispensing information such as “drug”) and usage information (eg, three times a day after each meal) is recorded in a two-dimensional code. It is also assumed that the prescription drug names include three types of drugs, drug A, drug B, and drug C.
It is assumed that the above three kinds of medicines are not contained in the housed medicine container 4 housed in the container storage device 103.

As an operation performed by the first worker, the empty manual-type medicine container 5a is placed on the balance platform 30. At this time, the introduction side lid member 121 of the manual type medicine container 5a is removed in advance, and the medicine introduction part 21a is opened. In a state where the manual-type medicine container 5a is placed on the balance table 30, the medicine injection section 21a is open upward.
The control unit 131 of the medicine weighing device 3 waits for reading of prescription information (step 1).

The pharmacist operates the barcode reader 32 of the medicine weighing device 3 to read dispensing information from the two-dimensional code attached to the prescription. When the two-dimensional code is read by the barcode reader 32 (YES in step 1), the control unit 131 advances the process to step 2.
Here, the dispensing information read from the two-dimensional code includes prescription delivery date, patient ID, patient name, patient birth date, drug information (drug code, drug name, dose, dosage form information such as “tablet, powder, etc. And information on external prescriptions such as ointments, ointments, etc.) and usage information (eg, three times a day after every meal).

  In step 2, the control section 131 displays a prescription screen (not shown) on the touch panel 133 based on the prescription information read in step 1. The prescription screen displays the dispenser name, patient name, age, weight, prescription days, minutes, drug name, dosage form, prescription amount, and the like.

  Next, in step 3, the control unit 131 waits for reading of the stored medicine name (NO in step 3). Specifically, the control unit 131 determines that the stored medicine name is read when the barcode reader 32 reads the stored medicine information indicated by the JAN code or the medicine bottle code recorded on the medicine bottle. . When the pharmacist holds the JAN code or the vial code of the vial over the barcode reader 32 and the barcode reader 32 reads the JAN code or the vial code (YES in Step 3), the control unit 131 Shifts the processing to step 4.

  That is, in the medicine weighing process, first, information such as prescription is read, and then the name of the contained medicine is read. Therefore, when the stored medicine name is read first, the weighing of the medicine weighing device 3 is not started.

  Then, in step 4, the control unit 131 branches the process in accordance with the result of the collation between the stored medicine name of the stored medicine information read in step 3 and the stored medicine name of the prescription information read in step 1. Specifically, in step 4, the control unit 131 determines whether or not the stored medicine name corresponds to any of the prescription medicine names.

  Here, if the accommodated medicine name corresponds to any of the prescription medicine names (YES side of step 4), the process proceeds to step 5, and if the accommodated medicine name does not correspond to any of the prescribed medicine names (step S4). (NO side of No. 4), the process proceeds to step S13.

  In step 5, the control unit 131 selects a prescription medicine name that matches the contained medicine name from among the prescription medicine names included in the prescription and the like information, as the weighing target. That is, when the accommodated medicine name corresponds to any of the prescription medicine names, the prescription medicine name to be weighed out of the prescription medicine names included in the prescription etc. information is automatically selected.

  Therefore, the pharmacist only checks the JAN code or the vial code recorded on the vial with the barcode reader 32 in the medicine weighing device 3 to check the name of the contained medicine and the prescribed medicine, and to check the medicine to be weighed. Can be realized. Therefore, when a plurality of prescription drug names are included in the prescription or the like information, the operation for selecting the prescription drug name to be weighed can be omitted, and the dispensing efficiency by the doctor or pharmacist can be improved. .

  In step 6, the control unit 131 causes the touch panel 133 to display a weighing screen (not shown) for weighing the medicine having the prescription medicine name corresponding to the accommodated medicine name from the prescription information. At this time, the control unit 131 causes the weighing value of the medicine by the balance unit 132 and the target value of the weighing of the medicine of the prescription medicine name to be displayed on the weighing screen.

  For example, the target value “0.9 g”, which is the prescribed amount of “drug A”, and the actual weighed value “0.0 g” by the balance unit 132 are displayed.

  Then, in step 7, the control unit 131 waits for completion of the weighing of the prescription drug name (NO in step 7). Specifically, the control unit 131 determines that the weighing of the prescription medicine name is completed by operating an enter key (not shown) displayed on the weighing screen. Then, when determining that the weighing of the prescription medicine name is completed (YES in step 7), the control unit 131 shifts the processing to step 8. In addition, when the weighing of the prescription medicine name is completed, the control unit 131 stores the fact in the data storage unit 135 (RAM) or the like.

  In step 8, the control unit 131 causes the touch panel 133 to display a progress screen (not shown) indicating the progress of the weighing of the prescription drug name in the prescription information.

  In step 9, the control unit 131 writes the dispensing information and the weighing result (an example of the weighed medicine information) to the RFID tag 22 of the manually-operated medicine container by the RFID reader / writer 134. The dispensing information includes prescription delivery date, patient ID, patient name, patient's birth date, drug information (drug code, drug name, dose, dosage form information "internal medicine such as tablets and powders, and external medicines such as ointments" )) And usage information (eg, three times a day after each meal) recorded on the prescription. The weighing result includes the name of the medicine to be weighed, the target weighing value, the actual weighed value, the collation result between the prescription medicine name and the contained medicine name, and the like. When the prescription drug name included in the prescription information is replaced with the generic drug name and weighed, information to that effect is also included in the weighing result.

  It is also conceivable that in step 9, the control unit 131 causes the RFID tag 22 to record only a part of the prescription information. For example, when a small storage capacity is used as the RFID tag 22, it is not possible to record all information such as prescription information and weighing results. Therefore, in this case, the control unit 131 may cause the RFID tag 22 to store at least the name of the medicine to be weighed. In this case, the medicine weighing device 3 and the main device 2 are communicably connected to each other via a communication network such as a LAN or the Internet, and the control unit 131 transmits information not recorded on the RFID tag 22 to the main device 2. It is possible. Main device 2 receives the transmitted information by a control device (not shown) and stores it.

  In the configuration in which the medicine weighing device 3 and the main body device 2 are connected via a communication network, simple fixed information (such as an identification number of information) stored in the medicine weighing device 3 in association with prescription information and weighing results. May be recorded on the RFID tag 22. In this case, when the fixed information is read by the main device 2, the main device 2 requests the medicine weighing device 3 to transmit the prescription information corresponding to the fixed information and the weighing result. Thereby, the prescription information corresponding to the fixed information and the weighing result are transmitted from the medicine weighing device 3 to the main device 2 via the communication network. Main device 2 receives the transmitted information by a control device (not shown) and stores it.

  Note that the processing procedures of step 8 and step 9 may be executed in the reverse order or may be executed substantially in parallel. That is, immediately after it is determined in step 7 that the weighing is completed, the prescription information and the weighing result may be recorded in the RFID tag 22 in step 9.

  Thereafter, in step 10, the control unit 131 determines whether or not the next stored medicine name has been read by the barcode reader 32. Here, when the control unit 131 determines that the next stored medicine name has been read (YES in step 10), the control unit 131 shifts the processing to step 4. On the other hand, when the next stored medicine name cannot be read (NO in step 10), the control unit 131 shifts the processing to step 11.

  In step 11, the control unit 131 determines whether or not all the weighing corresponding to the prescription information has been completed. Specifically, when the completion key (not shown) is operated, or when the weighing of all the medicines to be weighed included in the prescription information is completed, it is determined that all the weighing related to the prescription information is completed. .

  When the control unit 131 determines that the weighing of all the prescription information has been completed (YES in step 11), the control unit 131 shifts the processing to step 12. On the other hand, when the weighing of all the prescription information is not completed (NO in step 11), the control unit 131 shifts the processing to step 10.

  By the way, when a complete key (not shown) is operated, if there is a prescription medicine name whose weighing is not completed among the prescription medicine names included in the prescription etc. information, the pharmacist may forget to weigh. Therefore, when the control unit 131 determines in step 11 that the operation of the completion key (not shown) is performed, the prescription medicine name included in the prescription or the like information in which the completion of the weighing is input by the operation of the completion key If there is a prescription medicine name for which the completion of weighing has not been input by the enter key, the fact may be displayed on the touch panel 133. Thus, it is possible to warn the pharmacist of forgetting to weigh. Note that the control unit 131 determines whether or not the weighing of each prescription medicine name is completed according to the information stored in the data storage unit 135 (RAM) in step 7. Here, the control unit 131 at the time of executing the display processing corresponds to an incomplete display unit. In addition, the control unit 131 may display the display using characters, images, sounds, or light.

  Then, when all the weighing of the prescription information is completed, the control unit 131 causes the printer 140 to print the prescription information and the weighing result in the subsequent step 12. Specifically, the name of the patient, the name of the drug to be weighed, the target weighing value, and the actual weighed value in the drug weighing device 3, the prescription drug name and the name of the contained drug included in the prescription information read in step 1 are described. , A weighing time, a weighing operator, and the like are printed. That is, the control unit 131 causes the printer 140 to print only the record regarding the medicine weighed by the medicine weighing device 3.

  On the other hand, in step 4, if the stored medicine name read in step 3 does not correspond to any of the prescription medicine names (NO in step 4), the control unit 131 proceeds to step 13 and indicates that the medicine is different. A warning screen (not shown) is displayed on touch panel 133, and the process returns to step 3. Thus, it is possible to warn the pharmacist that the selection of the medicine bottle is erroneous, and it is possible to prevent a wrong medicine from being prescribed.

  As described above, the pharmacist using the medicine weighing device 3 allows the barcode reader 32 to sequentially read the two-dimensional code of the prescription and the like and the barcode of the medicine bottle to accurately and easily measure the medicine according to the prescription. It can be carried out.

  In particular, when the pharmacist causes the barcode reader 32 to read the barcode of the medicine bottle, the medicine weighing device 3 collates the stored medicine name and the prescription medicine name, and starts weighing the prescription medicine to be weighed from now on. The first name is selected. Therefore, when a plurality of prescription drug names are recorded on the prescription, the pharmacist can save the trouble of selecting the prescription drug name to be weighed.

With the above steps, the “drug weighing operation” ends. Subsequent to this, “drug packaging work” will be performed.
In the present embodiment, when the “drug weighing operation” is completed, the input side lid member 121 is attached to the drug input section 21a of the manual drug container 5a by the pharmacist's hand.
Then, the manual-type medicine container 5a is moved to the main body device 2 by a pharmacist's hand, and opens the door member 111 provided on the housing 40 of the medicine shelf area 100 shown in FIG. 3) is attached.
Thereafter, the main body device 2 automatically performs the packaging operation. That is, the information on the dispensing written on the RFID tag 22 of the manual-type medicine container 5a is read by the main body side information reading means (door portion) 113 such as an RFID reader provided inside the door member 111.
Then, the main body side information reading means (door part) 113 automatically determines the mounting destination of the manual drug container 5a based on the read information. In this embodiment, since two distribution dishes 7a and 7b are provided, which distribution dish 7a and 7b is used is determined. Further, in this embodiment, since three container vibration tables 11 are provided in the vicinity of each of the distribution dishes 7a and 7b, it is determined which of the container vibration tables 11 is to be equipped with the manual-type medicine container 5a.

Then, the manual-type medicine container 5a is placed on one of the determined container vibration tables 11 by the robot 110. That is, the robot 110 holding the manual-type medicine container 5a directly goes to the container vibration table 11 without going to the container storage device 103, and installs the manual-type medicine container 5a in the container storage device 103.
The distribution dishes 7a and 7b to be used may be selected depending on the properties such as the color of the medicine.
When the manually-operated medicine container 5a is placed on the container vibration table 11, the information on the dispensing written in the RFID tag 22 of the manually-operated medicine container 5a is read out there as well. That is, in the present embodiment, the RFID reader 16 is provided near the container shaking table 11, and the information on the dispensing is also read by the RFID reader 16 on the container shaking table 11 side.
The powder is divided according to the information on the dispensing. That is, one of the distribution dishes 7a and 7b rotates, and simultaneously vibrates the container vibration table 11. As a result, the manual-type medicine container 5a on the container vibration table 11 vibrates, and the powdered medicine inside moves slowly to the medicine discharge unit 20a side, and finally falls from the medicine discharge unit 20a to the distribution plate 7. That is, in the present embodiment, the powdered medicine falls directly from the manually-operated medicine container 5a to the dispensing dish 7 without passing through a conventional trough.
When all of the powder has been dropped, the rotation of the distribution dish 7 is stopped. Thereafter, according to the dispensing information, the powder on the dispensing dish 7 is divided into a predetermined number, and the medicine is scraped out by the scraping device 8 and put into the medicine packaging device 6 to be individually packed. Also, predetermined characters are printed on the packaging bag.

In this embodiment, when all the medicines in the distribution dishes 7a and 7b have been discharged, the groove cleaning operation is performed. That is, the scraping arm 46 of the scraping device 8 shown in FIG. 14 is swung, and the tip side is raised to take out the scraping mechanism 47 from the distribution dishes 7a and 7b.
Subsequently, the cleaning arm 50 of the cleaning device 43 is rotated to lower the cleaning brush 51 provided at the tip, and the cleaning brush 51 is inserted into the medicine supply groove 45 of the distribution plates 7a and 7b.
Then, while rotating the cleaning brush 51, the distribution plates 7a and 7b are rotated.
As a result, the residue of the medicine remaining in the medicine introduction groove 45 of the distribution dishes 7a, 7b is scraped off by the cleaning brush 51, and the soaring residue is sucked by the suction means. Thus, the inside of the medicine introduction groove 45 is cleaned.
When the groove cleaning operation is completed, the cleaning arm 50 is rotated to raise the cleaning brush 51 provided at the tip, and the cleaning brush 51 is taken out of the medicine supply groove 45 of the distribution dishes 7a and 7b.

After that, the scraping portion cleaning operation is performed.
That is, the turntable 48 built under the table is rotated, and the entire scraping device 8 is turned to move the scraping mechanism 47 of the scraping device 8 to the vicinity of the cleaning device 43. Then, the cleaning arm 50 of the cleaning device 43 is slightly inclined, and the cleaning brush 51 is pressed against the scraping mechanism 47 to rotate the cleaning brush 51. As a result, the residue of the medicine stuck to the scraping mechanism 47 is scraped off by the cleaning brush 51 and enters the brush cover. Then, the residual in the brush cover is sucked by the suction means. As a result, the scraping mechanism 47 is cleaned.

  There is no need to clean the trough 210 because the main unit employed in the present embodiment does not have the trough 210 as in the related art.

In the embodiment described above, the main body device 2 has the container storage device 103 (FIG. 2) in which the housed medicine container 4 is installed. The main device 2 includes a robot 110. However, the container storage device 103 and the robot 110 are not indispensable, and may not have them as in the main body device 170 shown in FIG. Further, in the above-mentioned main body device 2, the RFID reader 16 as the main body side information reading means is attached to each container vibration table 11, but it is not always necessary to provide the RFID reader 16 in all the units. It is sufficient that the RFID reader is provided in any part of the main device 2 or that the RFID reader is connected to the housing of the main device 2. Further, the RFID reader 16 may be provided only in one container vibration table 11.

As described above, the medicine dispensing apparatus 1 of the present embodiment also has a function of performing fully automatic packaging using the accommodated medicine container 4.
Hereinafter, fully automatic packaging will be described.
Fully automatic packaging is performed using the housed medicine container 4. As described above, the storage type medicine container 4 is filled with a specific medicine in advance, and is housed in the container storage device 103 in the medicine shelf area 100.
The container vibration table 11 employed in the present embodiment has a weight measuring means 56 for directly or indirectly measuring the weight of the accommodated medicine container 4. The main device 2 employed in the above-described embodiment includes a container storage device 103. Therefore, the main unit 2 has a function of automatically selecting the accommodated medicine container 4 in which the medicine is accommodated in accordance with the prescription, and automatically weighing the medicine in the main unit 2.
This function is exhibited by using the housed medicine container 4. In the main body device 2 of the present embodiment, a predetermined medicine is housed in the housed medicine container 4 in advance, and the housed medicine container 4 filled with the medicine is housed in the container storage device 103.
Then, the drum member 105 of the container storage device 103 is rotated to bring the desired container-type medicine container 4 closer to the robot 110. Then, the holding type medicine container 4 is held by the robot 110 and the arm or the like is operated to set the holding type medicine container 4 on the container vibration table 11.
When a plurality of medicines are blended and enclosed in one package, a plurality of storage-type medicine containers 4 are installed on the container vibration table 11.

Then, the container vibration table 11 is vibrated. As a result, the powdered medicine in the housed medicine container 4 moves slowly, is discharged from the housed medicine container 4, and falls on the distribution dishes 7a, 7b.
Also, before and after the start of the vibration, the distribution dishes 7a and 7b are rotated. Before and after the start of the vibration, the weight of the accommodated medicine container 4 is measured. In the meantime, the weight of the accommodated medicine container 4 is monitored, and when the total amount of the powdered medicine reaches a desired weight, the vibration of the container vibration table 11 is stopped.
That is, the original weight, which is the weight of the stored medicine container 4 before the medicine is discharged, is measured by the weight measuring means 56, and when the powdered medicine is discharged little by little from the housed medicine container 4, the weight measurement means 56 The weight of the container 4 is monitored. Then, when the current weight, which is the current weight of the storage type medicine container 4, matches or substantially matches the value obtained by subtracting the target discharge amount from the original weight, the discharge of the powdered medicine from the storage type medicine container 4 is stopped.

After that, the rotation of the distribution plates 7a and 7b is stopped, and division is performed.
This feature (full automatic packaging) is really useful, but not required. That is, the weight measuring means 56 is not essential. Because the total amount of the medicine to be distributed to the distribution dishes 7a and 7b is previously measured by the medicine weighing device 3, it is not necessary to stop the distribution operation halfway. Therefore, it is sufficient to be able to confirm whether or not the medicine has been discharged by an optical sensor or the like, and it is sufficient to be able to detect that all the medicine has been discharged from the manual-type medicine container 5.
That is, the weight measuring means 56, the container storage device 103, the robot 110, and the like included in the container vibration table 11 are not essential to the present invention.
Further, in the present embodiment, both the door member 111 and the container vibration table 11 are provided with the main body side information reading means, but either one may be used.
