Description

The present invention relates to a medicine packaging machine in which a plurality of medicine containers are arranged according to the kind of medicine.

(B) Conventional technology In general, a medicine packaging machine is configured by removably arranging a large number of medicine containers for each kind of medicine.
When the number, the number of packages and the like are input, the designated medicine container is driven to collect the medicines in the hopper, and the medicines are introduced into the packing section and packed. At this time, a code is assigned in advance to the location of each medicine container in the medicine packaging machine, and the name of the medicine contained in each medicine container and the corresponding code are registered in the device in advance. At the time of pre-packing, by inputting the name of the medicine, the corresponding medicine container is driven to introduce the medicine into the packaging section.

However, with such a configuration, the drug type is fixed for each location when the drug name and the code are registered in comparison with each other, so that the drug container is removed from the main body by refilling the drug or the like. If the place is wrong when re-installing, there is a problem that the medicine containers are interchanged and erroneously packaged.

For this reason, Japanese Patent Application Laid-Open No. 59-142901 has a switch for setting an absolute number for each medicine container, and outputs a code indicating the absolute number to each medicine container. There is disclosed a configuration in which only the drug is driven to take out the medicine.

(C) Problems to be Solved by the Invention In the above-described conventional technology, the medicine container can be driven as long as it matches the absolute number, no matter where it is installed. However, in this conventional technique, when a medicine is stored in a medicine container, an error occurs in taking out the medicine unless the absolute number representing the medicine is set correctly. For example, if the same absolute number is set to a plurality of medicine containers by mistake, the medicine may be taken out twice.

In general, a medicine packaging machine processes several hundred kinds of medicines, and a switch capable of recognizing hundreds of absolute numbers is not only large but also difficult to set.

Therefore, the present invention includes the card storing the medicine selection information, and the medicine container equipped with the card reader has the medicine selection information recorded on the card and the medicine selection information to be introduced coincide with each other. And a drug packaging machine that is driven.

(D) Means for Solving the Problems In order to solve the above problems, a medicine packaging machine according to the present invention is provided in accordance with the type of medicine and has a card on which medicine selection information for selecting a medicine to be packed is recorded. Each of the plurality of medicine containers, a card reader that reads the record information of the card, a medicine selection information for selecting a medicine to be packaged given from the medicine packaging machine body, and the record information of the card The apparatus is provided with a discriminating device for discriminating coincidence, and a driving device for performing an operation of extracting the medicine into the packaging portion when the discriminating device discriminates the coincidence.

(E) Action When the medicine selection information is given from the medicine packaging machine main body, each medicine container judges the coincidence between the record information of the card read by the card reader and the given medicine selection information by the judgment device. . When the medicine container detects the coincidence of the two information, the medicine container operates the driving device to perform the operation of extracting the medicine into the packaging part.

(F) Embodiment FIG. 2 is an external view of a medicine packaging machine, which comprises an operating device (10) and a packaging machine (11). The operation device (10) has a display device (3) and, for example, a key operation section as the input device (1). Displayed in (3).
The packaging machine (11) has a medicine container (2) for each kind of medicine.
(2), and a plurality of shelves (12)... (12) mounted in the horizontal direction are vertically arranged inside the housing. Then, the packaging machine (11) takes out the medicine from the predetermined medicine containers (2)... (2) based on the prescription information inputted to the input device (1), and introduces the medicine into the packing mechanism (13) through the hopper (5). .
The wrapping mechanism (13) includes a roll (7) around which the folded wrapping sheet (6) is wound, an arm (8) for applying a tension to the wrapping sheet (6), and a vertical sealing portion (31) on the wrapping sheet (6). ) To form a sachet (30), a vertical heat sealing mechanism (9), a sewing blade (4) for forming a cut in the packaging sheet (6) in conjunction with the vertical heat sealing operation, and a hopper (5). And a horizontal heat seal mechanism (10) for forming a horizontal seal portion for sealing the upper opening of the sachet, and a packaging sheet (6). ) Is transported intermittently in the longitudinal direction by 1 minute package length.

FIG. 1 is a block diagram showing a control circuit of the medicine packaging machine. An operation device (10) includes a CPU (20), an input device (1), a display device (3), and a memory (28). And
The packaging machine (11) includes a packaging control device (21) for controlling the packaging mechanism (13), and discriminating devices (22)... (22) provided for each of the medicine containers (2). .., (22) are connected to the CPU (20) via the data bus (23). A card reader (24), a driving device (25), and a medicine detecting device (26) are connected to the discriminating device (22), and each of the medicine detecting devices (26) is connected to a signal line (27).
Outputs a medicine detection signal to the CPU (20). The card reader (24) reads information of a card (29) inserted into the medicine container (2), and medicine information is recorded on a magnetic stripe of the card (29). The medicine information only needs to identify the kind of the medicine, and is, for example, a code indicating the name of the medicine or a medicine number. The medicine name is printed on the card (29) so as to be visible. When the medicine container (2) is filled with the medicine, the manager selects the card on which the medicine name is printed and selects the card. Plug in (2).

The operation of the above configuration will be described with reference to the flowchart of FIG. First, in step S1, when the prescription information of the medicine type, the medicine amount, and the number of packages is input to the input device (1), the CPU (20) displays the prescription information on the display device (3) and stores it in the memory (28). I do. When the CPU (20) determines in the next step S2 that a command to start packaging has been given by operating a predetermined function key of the input device (1), the process proceeds to step S3, where the medicine selection information is transferred to the data bus (23). ). Each of the medicine containers (2)... (2) is provided with the medicine selection information, and the discrimination device (22) judges the coincidence between the medicine selection information and the medicine information recorded on the card (29). When they match, the medicine container (2) operates the driving device (26) to perform the medicine extracting operation.

In response to the output of the medicine selection information of the CPU (20), the medicine container (2) containing the corresponding medicine performs the operation of extracting the medicine, and when the medicine is normally extracted, the medicine container (2) The drug detection device (26) outputs a drug detection signal to the signal line (27). Therefore, the CPU (20) determines the input of the medicine detection signal in step S4, and proceeds to the next step S5 when confirming the input. If the medicine detection signal is not input, the process proceeds to step S8, and the display device (3)
Displays a drug extraction error.

In step S5, the CPU (20) determines whether all the medicines to be extracted in one package have been extracted, and returns to step S3 if the extraction has not been completed. Therefore, the CPU repeats the processing from step S3, and outputs the input drug type selection information to the data bus (23) the number of times corresponding to the input drug amount. For example, if one package contains two tablets of medicine A and one tablet of medicine B, the CPU (20) repeatedly outputs the selection information of medicine A twice, and then outputs the selection information of medicine B. Is output to extract one package.

When one package of medicine has been removed, the CPU (20)
Supplies a control signal to the packaging control device (21) to control a series of packaging operations. In the next step S7, it is determined whether or not the packaging for the input number of packagings has been performed. If the packaging has not been completed yet, the process returns to step S3, and the processing for the next packaging is repeated.
When the operation for all the packages is completed, the process returns to step S1 to wait for input of the next prescription information.
