Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention provides a method for storing various types of tablets in respective tablet containers, and allowing the type and number of tablets to be packaged to be arbitrarily selected using an operating device; The present invention relates to a control device for an automatic drug packaging machine.

(B) Background The configuration of a general automatic tablet packaging machine (11) is shown in Fig. 1.A large number of tablet containers (1) are detachably arranged for each type of tablet, and an external When the type, number, and number of tablets to be packaged are specified using the operating device, the specified tablet container (1) is driven and the tablets are extracted into the hopper (9), and one package of tablets is held in the hopper (9). is the packaging department (10
), and for example, tablets are poured into small bags made by vertically sealing folded wrapping paper, and the openings are sealed for packaging.

At this time, a code is assigned in advance to each arrangement location of the tablet containers (1) in the automatic tablet packaging machine, and the name of the stored tablets of each tablet container (1) and the corresponding code are input to the operator. By registering the comparison by pressing the key, you can set the tablet@ type for each installation location, and when packaging, press the packaging device - Begi agent name manually, the coat will be read out visually, and the code (・The tablet container at the corresponding installation location is driven at the specified speed and the tablet is taken out.However, with this configuration, the tablet type is fixed for each installation location when the stored tablet name and code are compared and registered. Therefore, if the tablet container (1) is removed from the packaging machine for replenishing tablets, etc. and placed in the wrong place, the tablet containers (1) may be swapped with each other, resulting in incorrect packaging. In addition, it is often forgotten to reset the tablet container (1) that has been removed into the packaging machine, and in this case, the tablets are packaged with missing tablets.

←→ Purpose of the Invention In view of the above-mentioned points, the present invention makes it possible to select a tablet holder arranged at any location by key operation of an operating device by assigning a code to each tablet holder, and to The purpose of the present invention is to provide a device that can reliably prevent forgetting to set the device.

2) Overview In an automatic tablet packaging machine in which tablet containers for each type of tablet are arranged in a detachable manner, a code is assigned to each tablet container.
] When extracting tablets, a code specifies a specific tablet container, and if a matching signal is not obtained from any tablet container when specified by the code, the tablet container related to the code is FIG. 2 shows the control circuit of the operating device in a block diagram, where (2) is a function input section that outputs a control signal in response to the operation of the function E;
) is the electronic/yarakuta human resource department that outputs a character code code in response to the operation of the numeric keys and letter keys, and 0 and 0 are the character codes that store the absolute number of each tablet container and the name and abbreviation of the stored tablet type. I5) Prescription memory that stores the abbreviations of tablet types in the packaging device as character codes, and also stores the number of packaged tablets and the number of sachets, (16)
) is a coincidence logic circuit, (17) is a display device, (2) is an output device, (18) and us (19) are gate devices.

Then, when the tablets are stored in the tablet container (1), operate the function key to specify the registration mode using the function input section 02), and sequentially input the absolute number and name of the stored tablets into numbers for each tablet container (1). Settings are made using the keys and character keys, and by operating these keys, these information are introduced into the registration memory 04) through the gate device using character codes.In addition, in this example, the abbreviation of the tablet name can be entered manually using the keys. It is now possible to select the type of tablet to be packaged.
Therefore, in the registration mode, the abbreviation along with the absolute number and the name of the stored tablet is introduced into the registration memory (I4) by key operation in the form of a short code. Then, before starting the packaging operation, use the function keys to specify the input mode using the function input section α2), and enter the abbreviation of the tablet name to be packed, the number of tablets to be packaged for each tablet type, and the number of sachets using the numerical and letter keys. This information is introduced from the character input section 03) into the prescription memory (15) through the gate device (191).At this time, the display device (17
) displays the abbreviation introduced into the prescription memory 05), and the matching logic circuit (16) compares the abbreviation introduced into the prescription memory α5) with the abbreviation stored in the registration memo IJ I4) and determines if there is a match. The absolute number of the tablet container (1) containing the tablets whose abbreviations are changed and the number of packed tablets are introduced into the output device (2). On the other hand, when a match is detected in the match logic circuit (16), the registration memo 1) (14) introduces the character code of the tablet name and absolute number to the display device (I7), instead of displaying the abbreviation of the tablet until now. display device (17
)&''!-The official name is displayed and the absolute number is also displayed in the middle.In this way, the prescription memo 'J (1
, 5), the absolute number and the number of packaged tablets are introduced into the output device (2), and the output device (2) is set to the prescription memo (January 15). The number of wraps is also introduced by the matching logic circuit (16). Then, the output device (2) (the absolute number to be introduced, the number of packaged tablets, and the number of divided packages are stored in the memo 'J CMI), and the absolute number and number of packaged tablets are also stored in the memory (M2) and the function is When the packaging mode is specified by key operation, the memory (M)
) controls the tablet extraction operation based on the memory.

Figure 3 is a diagram showing the connection between the output device (2) and each tablet container (1), and the output device (2) is connected to the output lines N1 and N2.
. . . Nn specifies the absolute number of the tablet container (1) using a binary code, and a cent signal and a reset signal are output at the set line S and reseno trino R, respectively. Furthermore, each tablet container (X) is configured to output a signal to the output device (2) at line 12. Figure 4 shows the circuit of the tablet container (1) in a block diagram, (3) is a switch device that sets the absolute number in binary code, and (7) sets the set line S and reset line R, respectively. Flip-flop circuit connected to the side and reset side, (5) is a solenoid that is driven by the set output of the flip-flop circuit (7) to extract the tablet, and (4) is the output code and switch from the output device (2). Equipment (3
), (6) is a sensor disposed near the tablet drop opening of the tablet container (1) and generates a detection signal when it detects a extracted tablet; (8)
) is an A N D gate. and each tablet container (1
) and the comparator (4) are connected to lines i, , l, , respectively.

Next, the operation when the packaging mode is entered by operating the function keys will be explained with reference to the flowchart of FIG. First, the output device (2) reads the number of packed tablets or the absolute number of the tablet type stored in the memo jj (Ml) and outputs its binary code to the output line Nl-'N2...Nn. The comparison device (4) of the tablet container (1) outputs a set signal to the set line S, and therefore the absolute number outputted from the output device (2) is equal to the absolute number set in the switch device (3). ) gives a matching signal,
Furthermore, since this coincidence signal is introduced into the data terminal of the flip-flop circuit (7), and a set signal is introduced into the center side, the solenoid (5) is driven and the selected tablet type is selected. The eye pill extraction action begins. However, if the output code from the output device (2) does not match any tablet container (1) and no matching signal is generated on line 12, the output device (2) outputs the tablet container (1) associated with the tablet code. 1) is detected and the display device 07) displays a setting error of the tablet container (1). On the other hand, the tablet was extracted normally.

When the operation is started and the sensor (6) detects the extraction of tablets in each percentage and drug container (1), an extraction signal is sent to the AND gate (8) with the matching signal of the comparator (4). line 11] and input it to the output device (2), and the output device (
2) stores extraction signals for each tablet type in the memory (M3). A time of 250 mS is set, which is sufficient for the selected tablet container (1) to be driven to extract the tablet and to store the extraction signal in the memory (13). ) repeatedly outputs the absolute number 250m5
After the elapse of time, a reset signal is output to the reset line R to reset the flip-flop circuit and stop the tablet extraction operation. Furthermore, within this 25 Q rr+s period, the output device (
2) is synchronized with the repeated output of the absolute number and the memory (
In order to sequentially designate the assigned address according to each tablet container (1) of M3), even if the extraction signal from each tablet container (1) is on the same line 11, the predetermined address is is memorized. Moreover, the generation period of the extraction signal is 25-0m5
Although it is shorter than the time it takes for the output device (2) to output each absolute number, the output device (2)
2) All extracting signals from the driven tablet container (1) can be captured.

Then, the output device (2) subtracts the extracted tablets for each tablet type stored in memo +) (M3) from the number of packaged tablets for each tablet type stored in memo IJ (Ml), and the number of packaged tablets is calculated. ``When it becomes Q-1, ``1'' is similarly subtracted from the number of packages stored in the memory (Ml). However, if the number of packaged tablets is other than "0-", the memo IJ (M3) is reset and after a delay time, the absolute number of the tablet type whose number of packaged tablets is stored is read and output again in the memory (lyll). , drive the tablet container (1) for two muzzle extractions. still,
The above delay time is set because when two or more tablets are extracted, the same tablet container (1) is stopped and immediately restarted for the next extraction, but it is not mechanically possible to respond. . In this way, this operation is repeated according to the number of packaged tablets for each tablet type stored in the memo IJ (Ml), and tablets with muzzles, two muzzles, etc. ), and when the number of packed tablets for each tablet type becomes all "0", "1" is subtracted from the number of packages, assuming that the tablet extraction operation for one package has been completed, as described above. If the number is other than 0, the tablet extraction operation for the second package is started after the number of packaged tablets stored in the memo IJ (M2) is introduced into the memory (Ml), and the tablet extraction operation for the set number of packages is started. After this, the number of packages becomes rOJ and the operation ends.

(F) Other Embodiments In the above-described embodiments, the tablet container detects cent errors in () when the tablet packaging operation starts, but it is also possible to detect the cent error in the packaging standby state. That is, in the standby state, the output device (2) sequentially outputs the output code for each tablet type, and detects the presence or absence of a matching signal on the line 12 to determine the presence or absence of the tablet container (1) corresponding to the output code. It can be determined in advance.

(G) Effects According to the present invention described in detail above, in an automatic tablet packaging machine in which tablet containers can be arranged in a detachable manner, a switch device for setting the tablet container (core absolute number) is provided to control the output device. Since the tablet containers are operated by specifying absolute numbers, the arrangement locations of the tablet containers are not fixed, improving manageability. Furthermore, since the output device and each tablet container are connected through a common line, the device can be made smaller, which is effective for devices that handle many types of tablets. If a matching signal is not generated from any of the tablet containers due to the output of the code, a wrong setting of the tablet container can be detected, so that packaging errors can be prevented.
