Description

TECHNICAL FIELD The present invention relates to a drug packaging machine that includes a plurality of tablet cases each containing a drug and performs a drug discharging / packing operation based on prescription data.

(B) Conventional technology In general, this type of medicine packaging machine is provided with a plurality of tablet cases accommodating various types of tablets as described in JP-A-60-204430, and is input by a controller. It is configured to sequentially eject tablets one by one from the tablet case based on the prescribed prescription data.

On the other hand, in hospitals and pharmacies where drug wrapping machines are installed, it is desired to shorten the time required for dispensing operations, and it is desirable that the processing speed of the drug wrapping machines be high.

(C) Problems to be Solved by the Invention However, in the conventional medicine packaging machine, each tablet case stores different types of tablets, and the tablet discharging operation of each tablet case is individually controlled. For example, when 3 tablets of the same type are packaged in a 1-minute sack, the discharging time will be three times as long as the discharging time of 1 tablet, and if such a packing operation is repeated many times. Since the tablet case is frequently emptied, tablets have to be replenished many times, and the increase in the number of replenishments not only increases the labor of the user but also lengthens the time required for dispensing work. was there. That is, the conventional drug packaging machine performs the tablet discharging operation by the method of instructing the tablet case number of the packaging machine with the controller, and since the tablet packaging machine has only one tablet case number,
Even if tablets of the same type are stored in a plurality of tablet cases, it is impossible to simultaneously discharge tablets of the same type by such a method of designating the tablet case number.

The present invention has been made in view of the above circumstances, and can realize a high processing speed of a medicine packaging machine, particularly, a high processing speed when a plurality of tablets of the same type are packaged in one sachet. The purpose is to provide.

(D) Means for Solving the Problems The present invention is provided with a plurality of tablet cases having different tablet case numbers containing the same type of medicine, and instructing discharge of a plurality of agents for the same type of medicine. The plurality of tablet cases are simultaneously driven according to the tablet case numbers.

Specifically, the instruction method from the controller to the medicine packaging machine is the medicine name and the medicine data consisting of a plurality of tablet cases storing the medicine, and a storage device capable of storing a plurality of this medicine data in advance in the packaging machine body is provided. When a drug discharge operation is instructed, the tablet case number is obtained by searching the drug name in the storage device, and the drug discharge signal output to the tablet case is the tablet case searched above. When there are a plurality of tablet case numbers, the tablet case numbers are output so as to be driven simultaneously.

(E) Action With the above-described configuration, the medicine packaging machine of the present invention, when packaging a plurality of tablets of the same type in one-pack sachet, simultaneously ejects a plurality of tablet cases containing tablets of the same type. Therefore, the processing speed can be increased.
Further, even when such a packaging operation is repeated many times, the tablets in each tablet case are evenly reduced in small amounts, so that the frequency of replenishing tablets is reduced, and the number of times of replenishment is reduced, which reduces the user's time and effort. Not only can it be reduced, but the time required for dispensing work can be shortened.

(F) Example An example of the present invention will be described below with reference to the drawings.

The controller 10 creates prescription data by key operation of the key input unit 12 and transfers it to the packaging machine 11, and the packaging machine 11 uses the transferred prescription data and drug information (to be referred to as drug data hereinafter) to package the package. Take action.

FIG. 2 shows the structure of the packaging machine 11, in which the tablet case storage portion 1 is formed in the upper part, and the hopper 2, the shutter 3 and the tablet packaging machine mechanism 4 are arranged below the tablet case storage portion 1. A tablet case 5 is placed in the tablet case storage unit 1 according to the type of tablet, and the tablet case 5 is driven by input of a predetermined tablet discharge signal to take out the tablet, and a hopper is passed through a drop passage (not shown). It is configured to be introduced into 2. Here, a plurality of tablet cases 5 accommodating tablets of the same type are placed in the tablet case accommodating portion 1. The tablet wrapping mechanism 4 includes a roller 7 around which a wrapping paper 6 that can be heat-welded and is folded in advance is wound.
A tension roller 8, a printer 30 that prints the dose time on the wrapping paper, a vertical heat-sealing mechanism 9 that heat-seals the wrapping paper 6 vertically to form a continuous sachet, and a horizontal that seals the upper opening of the sachet into which the tablets have been placed. It is composed of a heat seal mechanism 10 and a feed roller 11. And the feed roller
11 is intermittently driven to convey the wrapping paper 6, and when the conveyance is stopped, a vertical heat seal forms a sachet, a shutter 3 is opened to insert a tablet into the sachet, and a horizontal heat seal seals the sachet. Each operation of is performed.

FIG. 3 shows a control circuit according to the invention, and 13 is a controller 10
The control circuit section 14 on the side is a control circuit section on the packaging machine 11 side, and is connected by a transmission line 17 via interfaces 15 and 16 for converting transmission data to serial and receiving data to parallel. The control circuit unit 13 includes a central processing unit 18
A system memory 19 in which the control procedure of the system is programmed, a keyboard interface 20 that detects an operation of the key input unit 12 and generates a key input signal, and a CRT.
A controller 21, a buffer memory 23 for storing prescription data consisting of keyed tablet type, number of drugs, and number of days, and a drug consisting of a tablet case number and a drug name (the drug code may be substituted or combined) The file memory 31 stores data.

On the other hand, the control circuit unit 14 includes the central processing unit 24 and the packaging machine 11.
System memory 25 in which the control procedure of the side is programmed,
A buffer memory 26 that stores prescription data including the tablet type, the number of agents, and the number of days transmitted from the control circuit unit 13, and a file that stores drug data including the tablet case number and the drug name, which are also transmitted from the control circuit unit 13. Memory 27,
Packaging machine controller 28 that controls the packaging operation of the packaging machine 11
And a printer interface 29 and registers R ₁ and R ₂ . It should be noted that a plurality of file memories 27 can be stored for the same kind of chemicals by changing the tablet case number.

In the above configuration, the control circuit unit 14 performs packaging control based on the prescription data and the drug data transmitted from the control circuit unit 13. The control circuit unit 14 controls the transfer mode between the control circuit units 13 and 14. It is started by transmitting a transfer request signal to 13. At this time, the control circuit unit 14 periodically transmits the transfer request signal in a state where the packaging control is not performed.

The operation of the control circuit unit 13 will be described below with reference to the flowchart of FIG. The central processing unit 18 determines the presence / absence of the transfer request signal in the N ₁ step, and determines the presence / absence of the key input in the N ₂ step if the transfer request signal is not output. When the key input unit 12 is operated and the name of the medicine to be packaged every morning, noon, evening, and before bed, and the number and number of days of the medicine are keyed in, the key input contents are changed according to the predetermined format in N ₃ step. Based on this, prescription data is created and stored in the buffer memory 23. On the other hand, when it is detected that the transfer request signal is transmitted from the control circuit unit 14 in the N ₁ step, the process proceeds to the N ₄ step to first determine whether or not the drug data including the tablet case number and the drug name is transferred. In the case of transfer, the process proceeds to N ₈ step and the drug data stored in the file memory 31 is transmitted to the control circuit unit 14. If not transfer chemicals data, it determines the presence or absence of prescription data shifts to N ₅ steps. When the key input for packaging have been made, the buffer memory in the processing of the aforementioned N ₃ steps and N ₄ steps
Prescription data is stored in 23 and drug data is stored in the file memory 31, and the prescription data is transferred to the control circuit unit 14 through the transmission line 17 in the N ₆ step. In the N ₇ step, the contents of the buffer memory 23 are cleared and the process returns to the N ₁ step.

The operation of the control circuit unit 14 of the packaging machine will be described with reference to the flowchart of FIG. When the transfer request signal is output and the medicine data is received in the M ₁ step, the M ₂ step is changed to the M ₃ step and the medicine data is stored in the file memory 27. If you have already received the drug data becomes M ₄ steps, and stores the prescription data to the buffer memory 26 at M ₅ step receives the prescription data. Next, whether or not the file memory 27 has chemical data determined in M ₆ step, if no outputs an abnormal signal at M ₇ steps.
Also, if there is drug data in the register R2 becomes M ₈ steps, the number of agents from the prescription data is stored. The contents of the M ₉ in the step register R2 determines whether "0",
If it is not "0", the tablet extraction operation for one package is started,
First, the drug name is searched in M ₁₂ step, and M ₁₃
Tablet case number in step is stored in the register R1, and then stored again register R2 subtracted by 1 from the M ₁₄ the stored agent number in the register R2 at step. Such behavior by repeated a M ₁₅ steps the agent number of register R2 is shifted to the M ₁₆ step becomes "0". On the other hand, M
_{If the} drug search fails in ₁₂ steps (that is, there are not enough tablet cases to accommodate multiple agents), move to M ₁₆ steps, and the discharge operation for the remaining number of agents will be the next operation. Will be turned.

In M ₁₆ step, it is judged whether the tablet case number is stored in R1 and if it is stored,
The extraction signal is output to the tablet case with M ₁₇ . M ₁₈
In the step, shift the address of R1 and judge whether another tablet case number is stored in M ₁₆ ,
Extraction signals are sequentially output to the tablet case.

In M ₁₆ step, R1 does have been stored tablet case number (i.e., 0), the process proceeds to M ₉ steps, until the number of agents R2 is 0, sequentially repeating the M ₁₂ ~M ₁₈ step.

For example, if there are five tablet cases prepared when the number of agents is instructed to five, and the extraction work is completed by one operation, and only three tablet cases are prepared, one tablet case is prepared. Three pieces are extracted by one operation, and the remaining two pieces are extracted by the second operation. On the other hand, if agent number of register R2 at M ₉ step is "0", the packaging operation of the packaging machine 11 becomes M ₁₀ step is performed, M ₁₁ number of days in step and M ₁₂ steps, i.e., 1 Formulation The packing operation of the minute tablets is performed.

(G) Effect of the Invention As described above, according to the present invention, the same kind of medicine is stored in a plurality of tablet cases having different tablet case numbers, and a plurality of medicines of the same kind is instructed to be discharged. And, multiple tablet cases can be driven simultaneously according to the tablet case number, and multiple tablets can be packaged in the packaging time for one tablet. Moreover, instructions from the controller to the packaging machine can be sent to the medicine name. And the drug data consisting of multiple tablet cases that store the drug,
When multiple tablets of the same type are stored in different tablet cases, and when multiple tablets of the same type are packaged in a 1-pack sachet, the ejection operation of the multiple tablet cases containing the same type of tablets is performed. The processing can be performed simultaneously, and the processing speed can be increased. Further, even when such a packaging operation is repeated many times, the tablets in each tablet case are reduced evenly in small amounts, so that the frequency of tablet replenishment is reduced, and the reduction in the number of replenishments reduces the user's time and effort. Not only can it be reduced, but the time required for dispensing work can be shortened.
