Description

[Detailed description of the invention] (a) Industrial application field The present invention is directed to a drug packaging operation based on prescription data in which multiple dosing times are set in one day, such as morning, noon, and evening. Regarding packaging machines.

(b) Prior art In general, tablet packaging machines are
As seen in the above publication, the tablet type and number of tablets are entered in advance using a key, and sachets are successively created based on this input data. However, in recent years, as shown in Japanese Utility Model Publication No. 57-4981, the dosing period has been printed on the sachets at the same time as they are formed, and as a result, multiple sachets have been created depending on the dosing period, even for one day. It has become possible to create . However, with conventional packaging machines of this kind, the first time to pack the dose is always determined. For example, if there are four times to take the dose: morning, noon, evening, and before bedtime, the packaging machine always starts with the morning dose. had started. Therefore, for example, when dispensing medication for 7 days, the first dose on the first day should be other than the morning in order to package it in order from morning to morning, afternoon, evening, and before bedtime for all 7 days. However, this amount was wasted in packaging. To prevent this, it is necessary to package six days' worth starting in the morning, and then re-input the dosing timing on the first day to separate the packets, which is extremely troublesome.

(C) Object of the Invention The present invention provides a drug packaging machine that can start the packaging operation from the first dose period (dose start time) on the first day of administration.

(d) Structure of the Invention The present invention provides a tablet packaging machine that performs packaging operations based on prescription data having multiple dosing times in one day such as morning, noon, and evening. When the data on the type of tablet to be taken, the data on the number of tablets, and the number of days of taking are input, the total number of sachets to be packed for each dosing period is calculated and memorized, and the start time of dosing on the first day of dosing is entered as the first sachet. Furthermore, on the first day of dosing, the corrected total number of sachets is calculated by subtracting the number of sachets for the dosing time before the start time of dosing from the total number of sachets, and the number of sachets is calculated and stored. The packaging operation is started according to the tablet type data and the number of drugs data regarding the dosing start time indicated in the data, and thereafter, the tablet type data and the number of drugs set at each dosing time are sequentially set according to the dosing time. A drug packaging machine is constituted by a packaging means that performs a packaging operation according to the data and stops when packaging of the corrected total number of sachets is completed.

(E) Embodiments of the invention FIG. 1 shows an external view of a tablet packaging machine, and the controller 1

0, and a feed roller 11.
Then, the feed roller 11 is driven intermittently to convey the wrapping paper 6, and when the conveyance is stopped, the packaging bag is formed by vertical heat sealing, the tablets are inserted into the packaging bag by opening the shutter 3, and the packaging paper is packaged by horizontal heat sealing. Each operation of sealing the bag is performed.

FIG. 3 shows a control circuit according to the present invention, where 13 is a control circuit section on the controller 10 side, and 14 is a control circuit section on the packaging machine 11 side, which is an interface that serially converts transmitted data and parallelly converts received data. 15 and 16 and are connected by a transmission line 17. The control circuit section 13 is connected to the central treatment device 18.
, a system memory 19 in which control procedures for the system are programmed, a keyboard interface 20 that detects operations on the key input section 12 and generates key input signals, and a CRT controller 21 .
It is composed of a buffer memory 23 that stores prescription data such as the type of tablet and the number of tablets entered by key. The control circuit section 14 then includes a central processing unit 24.
, a system memory 25 in which control procedures for the packaging machine 11 are programmed, and a buffer memory 26 that stores prescription data transmitted from the control circuit section 13.
, a control counter 27, a packaging machine controller 28 for controlling the packaging operation of the packaging machine 11, a printer interface 29, and registers _R1 and _R2 .

In the above configuration, the control circuit section 14 performs packaging control based on the prescription data transmitted from the control circuit section 13, but in the transfer mode between the control circuit sections 13 and 14, the control circuit section 14 requests transfer to the control circuit section 13. It is initiated by sending a signal. At this time, the control circuit section 14 periodically outputs this transfer request signal without performing packaging control. The operation of the control circuit section 13 will be explained below with reference to the flowchart shown in FIG. The central processing unit 18 is N ₁
The presence or absence of a transfer request signal is determined in step N2, and if the transfer request signal is not output, the presence or absence of a key input is determined in step _N2 . When the key input section 12 is operated and the name of the medicine to be packaged in the morning, afternoon, evening, and before bedtime, as well as the number of medicines and the number of days, are inputted, the _N3 step follows the format shown in Fig. 7. Prescription data based on this key input content is created and stored in the buffer memory 23. Figure ₅ is a flowchart explaining the operation of _{the N3} step.
indicates a storage area of the buffer memory 23 in which each data shown in the format of FIG. 7 is stored.

In FIG. 5, the _n0 step first writes the number of days data into the 1-byte storage area _M1 of the buffer memory 23, and converts the drug name specified by key input into a code indicating the tablet type. After writing to the memory area _M5 , and then specifying the drug name, the tablet type (morning, noon, evening, etc.) is entered by key.
Data on the number of drugs taken each time before going to bed is stored at 0 in the 4-byte storage area.
Write to each address from ~3. Figure 8 shows the display contents of the CRT22 in key input mode.
The name of the drug and the number of doses and number of days for each morning, noon, evening, and bedtime of this drug are displayed on the display section 3 by key input by the operator.
1, 32, and 33, respectively, and the tablet type code corresponding to the drug name is displayed on the display section 34. In the input example shown in Fig. 8, A lock, B lock,
This means that the key input is to pack C tablets and D tablets, one tablet each in the morning, afternoon, and evening for 7 days. Therefore, each storage area _M5 that stores tablet type codes No. 1 to No. 4 of the buffer memory 23 has the following information:
In the morning, noon, and evening of each storage area _M2 , tablet type codes corresponding to tablets A, B, C, and D are written, and data on the number of tablets from No. 1 to No. 4 is stored. The drug number data "1" is written in the corresponding addresses 0 to 3, respectively, and the number of days data "7" is written in the memo _M1 . n ₁ step each memory M ₂
The content of address 0 of M2 is determined, and if the content written to address 0 of at least one of _M2 is other than "0", the process moves to step _n2 . In the input example shown in FIG. 8, tablets A, B, C, and D are packaged one tablet at a time for morning use, so _n2 steps are required. The _n2 step writes data "7" stored in M1 to address ₀ of _M3 . In this way, it is determined that the number of packets for the morning dose is "7", and the CRT 22 displays "7" on the display section 33. In addition, regarding each tablet A, B, C, and D, for example, it is possible to package only A tablet in the morning dose and leave the others unpacked.
Since contents other than "0" are stored at address 0 of _M2 , the process moves to step _n2 and the number of parcels for the morning is set to "7". n ₄ steps with each M ₂
Shift the address of M ₃ , but in this case each M ₂ and
The address of M ₃ is shifted from 0 to 1. The _n5 step determines whether the address of _M3 exceeds 3 by shifting the address, and if the address does not exceed 3, the process returns to the _n1 step. In this _n1 step, it is determined whether a daytime package is required based on the contents of address 1 of each _M2 , and in the _n2 step, the number of daytime packages ``7'' is written to address 1 of <sub>M3</sub> . n <sub>4</sub> steps each M <sub>2</sub> and M <sub>3</sub> address 1
Shift from to 2. Then, from the <sub>n5</sub> step to the <sub>n1</sub> step, it is determined whether or not evening packets are necessary based on the contents of address 2 of each <sub>M2</sub> , and in the <sub>n2</sub> step, the number of evening packets ``7'' is transferred to _M3 . Write to address 2, shift the address of each M ₂ and M ₃ from 2 to 3 in step n ₄ , confirm that M ₃ has not exceeded in step n ₅ , and proceed to step n ₁ . In this example, as shown in Figure 8, since we do not take tablets before bedtime, the content of address 3 of each _M2 is "0".
The program moves to the _n3 step, and in the _n3 step, "0" is written to address ₃ of M3. Therefore, the number of sachets before going to bed is set to "0". Thus, in the _n4 step, the addresses of each _M2 and _M3 are shifted, but in the _n5 step, the address of _M3 is over, so the shift becomes a _n6 step.

With this process up to n ₅ , it is possible to pack 3 portions each for breakfast, lunch, and evening for all 7 days.M ₃
This means that it was set to . However, if you start taking the drug on the first day not in the morning but in the afternoon, evening, or before going to bed, modify the contents of _M3 by key operation. When there is a key input for such correction, the address to be corrected in _M3 is specified in steps _n6 to _n7 . For example, if you start taking the drug at noon on the first day, the number of packets for the morning dose needs to be revised to "6". Therefore, in this case, when there is a key input to correct the morning dose, in the _n7 step, address 0 of _M3 is specified, and following the correction key input, the number of packets data "6" input using the numeric keypad is input to n. Write in ₈ steps and return to ₆ steps. Through this correction operation, the screen of the CRT 22 becomes as shown in FIG.
If you also need to adjust your lunch and dinner doses,
By pressing the correction key and inputting the number of corrections using the numeric keypad.
Specify the address of _M3 and write the corrected value. When no correction is necessary or when the correction is completed, the user then key-inputs the time to start taking the drug: morning, noon, evening, or before going to bed. In this case, morning, afternoon,
Evening and before going to bed are predetermined as "1", "2", "3", and "4", respectively. For example, when the first day's medication is to start from noon, "2" is keyed in. Therefore
When a key input is made in step _n9 , "2" is written in the storage area _M4 of the buffer memory 23 as the first package data in step _n10 . When the prescription data is created in this way, the process returns from the _N3 step to the _N1 step, and the following explanation will be made using prescription data based on the input example shown in FIG. When it is detected in step _N1 that a transfer request signal is transmitted from the control circuit section 14, the process moves to step _N4 to determine the presence or absence of prescription data. When the key input for packaging is completed, the prescription data is stored in the buffer memory 23 in the process of the above-mentioned step _N3 , and the prescription data is sent to the control circuit section 14 through the transmission line 17 in the step _N5 . Transfer, but
At this time, the prescription data is serially converted by the interface 15 and transmitted. At the _N6 step, the contents of the buffer memory 23 are cleared and the process returns to the _N1 step.

The operation of the control circuit section 14 on the packaging machine 11 side will be explained with reference to the flowchart shown in FIG. When the transfer request signal is outputted and the prescription data is received in the N ₁ ' step, the process moves from the N ₂ ' step to the N ₃ ' step and the prescription data is stored in the buffer memory 26. The prescription data received at this time is
Then, the buffer memory 26 stores this prescription data in storage areas M ₁ ' to _{M 5} ' corresponding to the storage areas M ₁ to M ₅ of the buffer memory 23.
In the N ₄ ' step, the content CN of the control counter 27 is set to "1", and in the N ₅ ' step, the content CN of the control counter 27 is compared with the value of M ₄ '. M ₄ ′ stores the first package data of the prescription data, and in this case, the first package stores "2" for the daytime portion. Therefore, the process moves to the N ₆ ' step, the control counter 27 is incremented by 1, and the process returns to the N ₅ ' step. At this time, the control counter 27 and M ₄ ' match, and at step N ₇ ' it is determined whether the content of M ₃ ' is "0". _M3 ' stores the total number of packets for each morning, noon, evening, and before bedtime of the prescription data, but at this time, the content CN of the control counter 27 is incremented to "2". Address 1, which stores the total number of daytime packets, is specified in M ₃ '. In this example, the number of packets for lunch is 7 days worth, and M ₃ ′ stores “7”, so the N ₃ ′ step, which becomes the N ₃ ′ step, is stored in the storage area M ₅ ′ of the buffer memory 26. Store the tablet type code of the stored prescription data in register _R1 , and
The drug number data stored in the storage area M ₂ ' of No. 6 is stored in the register R ₂ . At this time, regarding M ₂ ', since the control counter 27 is counting "2", the drug number data stored at address 1 of each M ₂ ' is read out and stored in the register _R2 .
Therefore, the tablet type code of each tablet A, B, C, and D is written in the register _R1 , and the data on the number of tablets in the daytime packet for these tablet types is written in the register _R2 . The _N9 ' step determines whether the contents of register _R2 are "0" or not, but if the number of tablets data for at least one tablet type is other than "0" for each tablet type A, B, C, and D. At the N ₁₀ ' step, the tablet is extracted. In the _N10 ' step, the tablet type code for the tablet type whose drug number data is other than "0" is registered in the packaging machine controller 28.
Read from _R1 and introduced. Then, the packaging machine controller 28 outputs an extraction signal to the tablet cases 5...5 containing various tablets A, B, C, and D. Therefore, the tablet cases 5 to which the extraction signal has been introduced are driven to extract one tablet. In the N ₁₁ ' step, "1" is subtracted from the tablet number data for the tablet type for which the extraction operation was performed, and the process returns to the N ₉ ' step. In this example, in order to package each tablet of each tablet for the daytime meal, the various tablets A, B, C, and D are stored in register _R2 . Since the data on the number of drugs becomes "0", the step changes from the N ₉ ' step to the N ₁₂ ' step. Therefore, one daytime packet of tablets has been extracted and introduced into the hopper 2. In the _N12 ' step, print data for printing "daytime" is output to the medicine packaging printer 30, and the printer 30 is driven to control printing on the wrapping paper 6. At step _N13 ', the packaging machine controller 28 gives control signals to the shutter 3, horizontal heat sealing mechanism 10, and vertical heat sealing mechanism 9, respectively, to control each operation of inserting tablets, sealing sachets, and forming sachets, Thereafter, a control signal is applied to the drive device of the feed roller 11 to transport the wrapping paper 6 by a predetermined length in the longitudinal direction, thereby completing the wrapping operation of the daytime packet. The _N14 ' step subtracts "1" from the data stored at address 1 of M3' in the buffer memory ₂₆ ,
In the _N15 ' step, it is determined whether the data at all addresses 0 to 3 of _M3 ' are "0". In this case, one daytime packet has been completed and "1" is simply subtracted from the data at address 1 of M ₃ ', and in the N ₁₆ ' step, the addresses of M ₃ ' and each M ₂ ' are is shifted from 1 to 2 and returns to the N ₇ ' step.
Then, in the N ₇ ' step, it is determined whether the content of address 2 of M ₃ ' is "0", but at this time, the content of address 2 is "7", so the process moves to the N ₈ ' step and the evening portion is stored. It becomes a wrapping motion.

In the N ₈ ′ step, the tablet type code stored in M ₅ ′ is stored in register R ₁ , and the drug number data stored in address 2 of each M ₂ ′ is stored in the register.
Store in R ₂ . Then, from the _N9 ' step to the _N10 ' step, tablets are extracted from tablet cases 5...5 for tablet types whose data is other than "0" for the number of drugs stored in register _R2 ,
In step _N11 ', "1" is subtracted from the drug number data in register _R2 . In this example, since each tablet A, B, C, and D is packaged one by one for the evening dose, the data on the number of pills in register _R2 is all "0", and from step _N9 ' to _N12 ' step. In the N ₁₂ ′ step, “Yu” is printed on the wrapping paper.
In the N ₁₃ ' step, the tablets taken out into the hopper 2 are packed, and in the N ₁₄ ' step, "1" is subtracted from the data stored at address 2 of M ₃ ', and the tablets are packed. It is memorized that the 1-pack operation has been completed. Then, when the step changes from the N ₁₅ ' step to the N ₁₆ ' step, the address of M ₃ ' and each M ₂ ' is shifted from 2 to 3, and the process returns to the N ₇ ' step. According to the prescription data of this example, the content of address 3 of M ₃ ' is "0" because the medication is not administered before going to bed, and the steps range from N ₇ ' to N ₁₅ '. Therefore, the packaging operation for the dose taken before bedtime is omitted. and from N ₁₅ ′ step
At the _N16 ' step, the addresses of _M3 ' and each _M2 ' are shifted from 3 to 0, and the process returns to the _N7 ' step. At the N ₇ ' step, the content of address 0 of M ₃ ' is "6", so the process moves to the N ₈ ' step, and the morning portion packaging operation is performed.

In the N ₈ ′ step, the tablet type code stored in M ₅ ′ is stored in register R ₁ , and the drug number data stored in address 0 of each M ₂ ′ is stored in the register.
Store in R ₂ . Then, each drug A, B, C, and D is taken out one tablet at a time from the tablet cases 5, . Further, in the N ₁₆ ' step, the addresses of M ₃ ' and each M ₂ ' are shifted from 0 to 1, and the process proceeds to the N ₇ ' step.
At this time, "6" is stored in address 1 of M ₃ ', and the second packaging operation for lunch will be performed. In this way, the packaging operation is repeated in the order of noon, evening, and morning until the contents stored in addresses 0 to 3 of M3 _' of the buffer memory 26 are all "0". Therefore, since the first package starts at noon, six packages are packed for the morning dose, and seven packages each for the lunch and evening doses. However, when the packaging operation for the 7th packet for the evening meal is completed and the contents stored in addresses 0 to 3 of M3 _' become all "0", it is assumed that the packaging operation for the 1st prescription data has finished. Return from N ₁₅ ′ step to N ₁ ′ step.
Then, in step _N1 ', a prescription data transfer request signal regarding the next packaging operation is transmitted to the control circuit section 13.

In this manner, the present invention stores the entered dosing start time on the first day of dosing as the first packet data, and also allows correction input of the number of sachets when the dosing start time is other than in the morning. At the time of packaging, the first package to be packed is located based on the first package data, and the predetermined number of packages are then sequentially packaged for each dose period.

(f) Effects of the Invention According to the present invention, the start time of the first day of administration is stored as the first package data, and when packaging, the first package data is used to locate the first package to be packaged. Packaging can be done in line with the start time. In addition, if the starting time for taking the drug is other than the morning, it is possible to input the correct number of sachets, so it is possible to pack just the right amount of sachets for each dosing period. Moreover, the excess or deficiency in the number of sachets can be adjusted only by inputting the leading sachet data and making correction inputs, making the operation extremely easy.
