Description

Detailed Description of the Invention (a) Industrial Application Field 3 The present invention provides a tablet packaging machine that can be used in hospitals etc. to selectively dispense one or several types of tablets based on different prescriptions for each patient. Regarding the control method.

(b) Prior Art Currently, there are thousands of types of tablets prescribed in hospitals, etc., but the tablets actually used are limited to about 800 glazes.

However, the current tablet packaging-like structure is limited to storing approximately 250 types in one device, and therefore, in large hospitals, it is not only extremely cumbersome to have to change tablet cases frequently, but also Occasionally, a mistake in setting the tablet case would cause the tablet packaging machine to stop operating or lead to incorrect packaging. For this reason, large hospitals have begun to install several tablet packaging machines side by side to dispense prescriptions, but this requires a large space in the pharmacy, and operators are unable to manage each tablet packaging machine. It was a huge amount of effort.

(c) Purpose In view of the above, the present invention provides a tablet packaging machine control system that allows a single controller to efficiently control a plurality of tablet packaging machines installed in parallel.

2) Configuration: A system in which multiple tablet packaging machines are installed in parallel to one controller, and when prescription data indicating the type of tablet, number of drugs, and number of sachets is input, the controller is configured according to the data. A tablet packaging machine that accommodates the tablet type is selected, the selected tablet packaging machine transfers the prescription data in a non-operating state, and the tablet packaging machine that receives the prescription data performs the specified packaging operation.

(E) Embodiment Figure 1 shows the configuration of a tablet packaging machine, in which a tablet case storage section is formed at the top, and a hopper is located below it.
2), a shutter (3) and a tablet packaging mechanism (4). Tablet cases (5)...(5) are placed in the tablet case storage section (1) according to the type of tablets, and the tablet cases (5)...(5) respond to predetermined extraction signals. It is configured to be driven by an input to extract tablets and introduce them into a hopper (2) through a falling passage (not shown). The tablet packaging mechanism (4) includes a roller (7) around which a wrapping paper (6) that can be thermally welded and is folded in half beforehand is wound, a tension roller (8), and a wrapping paper (6).
It consists of a vertical heat-sealing mechanism (9) that vertically heat-seals the tablets to form a continuous pouch, a horizontal heat-sealing mechanism (00) that seals the upper opening of the pouch into which the tablets are inserted, and a feed row 201). 1, and the feed roller α■) is driven intermittently to convey the wrapping paper (6), and when the conveyance is stopped, the pouch is formed by vertical heat sealing and the shutter (3) is driven intermittently to convey the wrapping paper (6).
) is opened to insert tablets, and lateral heat sealing is used to secretly issue a pouch.

In the present invention, a plurality of the tablet packaging machines described above are installed in parallel, and their operations are controlled by a single controller on the host side. FIG. 2 is a block diagram showing a system according to the present invention, (1 is a controller on the host side, (13A) (13

In addition, the circuit section of each tablet packaging machine (13A) (13B)... includes a processing device ■, a prescription backer memory (21), a packaging machine controller, an interface, and a CRT display device t23. It consists of The tablet packaging machines (13A,) (13B)... are classified by subject such as internal medicine or surgery, and the tablet types used in that subject are tablet cases (5)...(5).
It is stored in ~・ru. And storage tablet file (17A
) (17B) When setting the drug type to..., press α on the keyboard.
■Tablet packaging machine (13A) (]3B) to specify the registration mode and register by operating the function keys (13A) (3B)...

At the same time, with this registration operation, the search memory surface of each tablet packaging machine (
The abbreviations and code numbers of all tablet types stored in 13A) (13B)... are stored. Also, tablet cases (5) for each tablet packaging machine (13A013B)...
... = (5) are each equipped with a switch device, and a code number corresponding to the type of stored tablet is set in binary code.

FIG. 3 is a main flowchart showing the operation of the CPU (14). By operating the prescription data key on the keyboard, the CPU (14) is interrupted and enters the prescription data shown in the flowchart in FIG. Process. In FIG. 4, the CPU (14) first determines whether prescription data can be stored in the prescription buffer memory αQ, but if 10 types of prescription data are already stored in the prescription panzer memory σ6), the CPU (14) inputs the prescription data. It is assumed that prescription data cannot be stored and the process returns to the main flowchart of FIG. If the prescription data can be stored in the prescription buffer memory Q61, the CPU (If) compares each abbreviation stored in the search memory αD with the abbreviation key-in related to the next tablet type and stores the specified tablet type. Detects the drug name and code number and creates a prescription Panza Memory 06
). At this time, the CRT display device (18) first displays the key-in abbreviation, and then displays this drug name by the drug name detection by the CPU (1 (a)). When the number of drugs is keyed in sequentially, the CPU (14) &Mako's data on the number of drugs is introduced into the prescription buffer memo! By operating the drug type specification end key on the keyboard (151), the number of doses (i.e., the number of sachets) is entered into the mode for specifying the number of sachets, and CPTJI inputs the number of sachets entered by the key into the prescription buffer memo v (16). After setting, the CPU (14) stores the code number stored in the prescription buffer memory (L6) and each stored tablet file (17A) (17B)...
It sequentially compares the code numbers stored in Store the code in the prescription sofa memory (L6). This control code is for tablet packaging machine (

However, if the contents of the prescription buffer memory α6) do not match any of the stored tablet files (17A), (17B)..., error processing such as displaying a prescription input error on the CRT display Q8) is performed. Waits for the abbreviation key-in again. When the prescription data is successfully entered, the CP
U(14) returns to the main flowchart of FIG. To explain the operation of the main flowchart, the tablet packaging machines (13A) (13B)... that are in the process of packaging are setting the BSY flag indicating that they are in operation, and the CPU α4)
scans the tablet packaging machines (13A013B)... that are in an inactive state based on this BSY flag, and when it detects a tablet packaging machine (13A) (13B)... that is in an inactive state, it displays information regarding the tablet packaging machine in question. It is determined whether the control code is stored in the prescription buffer memory α6). Then, if the corresponding control code is stored, the CPU (1
4) Outputs this control code to the common bus (c) and sends it to the corresponding tablet packaging machine (13A) (13B)...-
Only the processing unit - is set to the data reception mode, and the CPU α
4) transmits the prescription data stored in the prescription buffer memory 06) to this processing device (20), and then clears the contents of the transmitted prescription data from the prescription buffer memory (16). In this way, the CPU (14) repeats this process for each tablet packaging machine (13A) (13B)... which is in an inactive state.
... is detected, and if this tablet packaging machine stores the tablet type of prescription data stored in the prescription buffer memory αe, this prescription data is sent to the processing device @) and cleared. And when interloved, CP
U (14) selects an empty storage area of the prescription memory (t6) and stores input prescription data.

FIG. 5 shows a flowchart of the processing equipment (company) in the tablet packaging machines (13A), (13B), etc. When each processing device receives a control code from the CPU (14), it deciphers whether this control code is a designated code for itself.Assuming that the CPU α4) designates the tablet packaging machine (13A), After setting the BSY flag, the corresponding processing device (■) transfers data to and from the CPU (14), and transfers the contents of the prescription buffer memory (16) on the host side to the prescription buffer memory 01 of the tablet packaging machine (13A).
). Therefore, the processing device stores the stored tablet type data and the number of tablets stored in the prescription buffer memory 02 in the memory M,
The tablet type data to be extracted is stored in the memory M on the condition that the value is not 0. Then, the tablet type stored in the memory M2 is detected and the corresponding code number is output to the packaging mechanism.

When the packaging machine controller (c) receives an input signal indicating a code number, the tablet case (5) containing the tablet type corresponding to that number is driven to discharge the tablet. A coma sensor is installed at the tablet dropout opening at the bottom of the tablet case (5), and the time from the output of the processing device (e) & ma code number until the sensor introduces a detection signal from the ejected tablet is 250 ms. It is on standby for a while. When a detection signal is introduced from each tablet case that outputs the code number, the processing device outputs the detection signal to the memo IJM. In addition, when there are multiple tablet types, the processing device (2) outputs the code number for each tablet type sequentially in a time-sharing manner, and
After 0 ms has passed, make a memo of each detection signal for each tablet type that occurs at a predetermined timing in the order in which the code number is output.
Sequentially store in s. However, after writing to memory M is completed, processing device ■ memo! The contents of J M2 and Ms are compared to determine whether all the designated tablet types have been discharged, and if they are equal, 1 is subtracted from the number of tablets for each tablet type. However, if the contents of the memories M2 and M do not match, the processing device outputs an abnormality signal to the CPU (14),
Next, the drug name data of the tablet type that was not discharged is transferred. When the data transfer with the processing device (a) of the tablet packaging machine (1, 3A) is completed, the CPIJ (14) can perform key-in for the next prescription, but performs an interrupt process when an abnormal signal is input. In this interrupt process, the CPU (14) receives data on the name of the drug that is abnormal from the processing device, introduces it to the interface (11), displays the name of the drug on the CB and T display devices α, and displays the drug name data that is abnormal. Show that something is true.

, a comparison device (c) that compares the code number introduced from the processing device with the code number set in the switch device (5), a memory circuit (a)), and a drive device ( (to). With this configuration, when the processing device (A) outputs a set signal together with a code number, a matching signal is obtained from the comparison device @ of the tablet case (5) corresponding to the code number and sent to the data terminal of the storage circuit. Since a set signal is introduced from the processing device through the memory circuit t29)), the drive device starts operating. If there are a plurality of tablet types to be discharged, a code number for each tablet type is output, and at the same time a set signal is output to sequentially set the memory circuits. However, after 250 ms have elapsed, the processing device -
scans the detection signal on line I in a time-division manner, detects the presence or absence of tablet ejection for each tablet type whose code number has been output at each timing, and outputs a reset signal through line R to reset the memory circuit.

In the flowchart of FIG. 5, it is detected that the first tablet of the specified tablet type is ejected normally, and the contents of the memories M7 and M3 are the same, and based on the data on the number of tablets for each tablet type stored in the memory M1. When 1 is subtracted, the processing device (A) is memo I.
Based on the data on the number of tablets of JM, it is determined whether or not the second tablet needs to be removed. Then, when it is determined that it is necessary to eject the second tablet, the processing device (
In b), the tablet type that requires the second tablet to be extracted is stored again in the memory M2 and the above operation is repeated. When the data on the number of drugs in the memory M1 becomes all 0, the processing device (a) enters the packaging machine control mode, and the packaging machine controller (company) controls the shutter (3), the horizontal heat seal mechanism aa, and the vertical heat seal mechanism. (9) respectively to control the tablet loading, pouch sealing, and pouch forming operations, and then, a control signal is given to the drive device of the feed roller (11) to move the wrapping paper (6) in the longitudinal direction. A predetermined dimension is transferred to. When this transfer is completed, one sachet is packaged, but next, the processing device (a) subtracts 1 from the sachet number data stored in the prescription buffer memory I21) so that the sachet number data does not become 0. case,
The tablet type data and the drug number data in the prescription buffer memory Qυ are stored again in the memory M, and the second package is packed. When the specified number of sachets is completed and the sachet number data in the prescription buffer memo IJ C1,) becomes O, the processing device (a) resets the BSY flag and starts the tablet packaging machine (
13A) ends the operation. This tablet packaging machine (13A)
During operation, the CR1 display device (c) displays the contents of the prescription buffer memo (IJ CHI) under the control of the processing device, and when the processing device (a) detects non-ejection of a tablet, it displays the drug name of the tablet type. Control is performed to display on the CR1 display device (c).

As described above, when the CPU (14) receives prescription data, the tablet packaging machine (14) containing the tablet type according to this prescription data (
13A) (13B)... is selected, and the prescription data is transmitted when the selected tablet packaging machine is in the non-operating state.

The tablet packaging machine (13A) (1) that received the prescription data
3B)... sets a flag indicating the operating state and starts the wrapping operation. If multiple prescription data are input and the same tablet packaging machine is driven by these prescription data, the same tablet packaging machine will operate repeatedly for each prescription data, and if the tablet packaging machines driven by different prescription data are different, all the corresponding tablet packaging machines will operate repeatedly. Two tablet packaging machines are driven at the same time.

(F) Effect According to the present invention, the controller selects a tablet packaging machine storing the tablet type according to the prescription data by inputting the prescription data, and transmits the prescription data to a plurality of tablet packaging machines using one controller. can control tablet packaging machines. Furthermore, since a tablet packaging machine is selected based on prescription data, each tablet packaging machine can be used to classify the tablets to be stored according to subject or symptom, thereby improving the efficiency of pharmacy operations.
