Description

Technical Field

[0001] The invention belongs to the technical field of cigarette logistics sorting and coding, and in particular relates to a shutdown alarm device for a repeater of a coding system. Background Art

[0002] In the modern cigarette sales process, sorting to households is achieved by the sorting system, and coding is achieved by the coding system. The coding industrial computer stores the order information that needs to be coded, and generates the coding order according to the specified sequence. The sorting link sorts the goods according to the order. In principle, each order is marked with its own barcode. In the overall operation process, the repeater is responsible for receiving and issuing the information that needs to be coded, realizing the centralized and unified scheduling function of the coding information.

[0003] like Figure 1 As shown, the coding system includes a repeater, a coding detection sensor, a coding industrial control computer, a coding machine, and an audible and visual alarm light. The repeater is connected to the coding detection sensor, coding industrial control computer, coding machine, and audible and visual alarm light. When the coding detection sensor detects goods, the signal triggers the repeater, which requests the coding industrial control computer for the required coding information in real time and sends the received information to the coding machine. The repeater receives the coding signal through serial port COM1 and communicates with serial port COM3 of the coding industrial control computer. The coding signal is sent through serial port COM2 and COM4 of the coding machine. When all the internal information of each order is coded, but before the customer switching signal is completed, the repeater outputs a signal to the terminal, causing the yellow light to light up, indicating the customer switching waiting state. After the repeater receives the cut-off signal, it triggers the coding industrial computer to determine whether the current order has been issued. If all orders have been issued, it will switch to the next order. If there is any information that has not been issued in the current order, the order switch will not be realized at this time. After the repeater sends a coding request message to the coding industrial computer, it will not receive the coding information. This time, the repeater will output an alarm signal through the terminal to prompt manual fault handling. After the manual service fault is handled, the order is switched manually to realize the order switching and the verification of the coding information, which effectively ensures the accuracy of the coding information.

[0004] The coding system's red light illuminates when it's in alarm, yellow when paused or stopped, and green during normal coding. After all cigarette cartons for the current sorting order have been coded, the audible and visual alarm light connected to the repeater flashes yellow and then green. The sorting line then outputs a household separation signal to the repeater. Normally, the repeater receives the household separation signal and resumes coding. Once the coding for that household's order is complete, the audible and visual alarm light flashes yellow and then green. If the repeater malfunctions, the audible and visual alarm light flashes yellow and then no longer turns green, but the sorting line continues to output the household separation signal to the repeater. This repeater failure results in the cigarette cartons not being coded in the coding system, while the sorting line does not alarm and shut down. By the time the anomaly is discovered, a large number of cigarette cartons have already been left uncoded. In these situations, the cigarette wrapping film must be removed and the cartons manually placed on the coding belt for manual coding. This is inefficient, time-consuming, and labor-intensive, severely impacting cigarette sorting operations. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device which utilizes the sound and light alarm light signal of the coding system and the household signal of the sorting system, and uses a downtime alarm shutdown device to realize the automatic shutdown of the sorting system and the independent shutdown of the coding system while the sorting system is debugged and operated.

[0006] A shutdown alarm device for a repeater of a coding system, comprising the shutdown alarm device, a repeater of the coding system, an audible and visual alarm light, and a sorting line PLC;

[0007] The coil KA1 of relay one is connected in series between the output terminal Q of the sorting line PLC and the common terminal, and the contact switch K3 of relay three is connected in series between the power supply and the common terminal of the sorting line PLC; the repeater signal is connected to the sound and light alarm light, and the coil KA2 of relay two is connected in series between the green light line of the sound and light alarm light and the common input terminal of the repeater;

[0008] The shutdown alarm and shutdown device uses a PLC controller, which contains two COM terminals and one 24V+ terminal. It also has at least input terminals X000~X002, output terminal Y000, common terminal COM0 of the output terminal, L and N terminals, and a data register; the coil KA3 of relay three is connected in series between the output terminal Y000 and the 24V+ DC output terminal, one COM terminal is electrically connected to COM0, a transistor is connected in series between the output terminal Y000 and COM0 inside the shutdown alarm and shutdown device, and the contact switch K1 of relay one, the contact switch K2 of relay two, and the reset switch SB1 are connected in series between the other COM terminal and the input terminals X000, X001, and X002 respectively;

[0009] According to the built-in control program, when the input terminal X000 of the downtime alarm and shutdown device receives signals twice in succession and the input terminals X001 and X002 do not receive signals, it is determined that the repeater has crashed, and the internal driving circuit of the downtime alarm and shutdown device turns on the transistor.

[0010] When the input terminal X000 of the shutdown alarm shutdown device receives signals twice in succession and the input terminal X001 or X002 receives a signal, it is determined that the repeater is normal.

[0011] The shutdown alarm device performs the following operations according to the built-in control program:

[0012] The shutdown alarm device generates a pulse signal when it is powered on, and the trigger data register is initialized to 0;

[0013] When the output terminal Q of the sorting line PLC outputs 24V, the coil KA1 of relay 1 is energized, thereby controlling the contact switch K1 of relay 1 to close. The input terminal X000 of the shutdown alarm device receives the signal from the common output terminal COM, and the value of the data register is increased by 1.

[0014] When the green light of the repeater's sound and light alarm indicator is on, the coil KA2 of relay 2 is energized, thereby controlling the contact switch K2 of relay 2 to close. The input terminal X001 of the shutdown alarm device receives the signal from the common output terminal COM, and the value of the data register is reset to 0.

[0015] When the reset switch SB1 is closed, the input terminal X002 of the shutdown alarm device receives the signal from the common output terminal COM, and resets the value of the data register to 0;

[0016] When the value of the data register is greater than or equal to 2, the internal drive circuit of the downtime alarm shutdown device turns on the transistor, the coil KA3 of relay three is energized, the contact switch K3 of relay three is closed, and the common end of the sorting line PLC receives a signal, indicating that the repeater is down. When the value of the data register is lower than 2, the internal drive circuit of the downtime alarm shutdown device will not turn on the transistor.

[0017] The shutdown alarm device uses the MELSEC FX1S-10MR series PLC controller.

[0018] The base of the transistor is electrically connected to the internal driving circuit of the shutdown alarm device.

[0019] After the shutdown alarm and shutdown device of the present invention is put into use, the sorting line PLC can promptly alarm and shut down when a repeater fails, effectively solving the problem of batches of cigarette cartons not being coded due to this. It has also been found in practice to solve the problem of batches of cigarette cartons not being coded due to the cigarette coding system not starting to code while sorting is in progress.

[0020] In addition, the shutdown alarm device of the present invention does not interlock the coding system and the sorting system. Therefore, when the sorting system is debugged and processed separately, the coding system can be shut down, allowing the sorting system to independently run a sorting operation (that is, allowing the sorting line PLC to output two household sorting completion signals). When the sorting system is operated independently, it is not necessary to always keep the repeater's sound and light alarm light green, or the sound and light alarm light yellow for a period of time that does not exceed the threshold.

[0021] The downtime alarm and shutdown device of the present invention provides more accurate signals, eliminates false alarms, and offers greater operational flexibility, convenience, and user-friendliness. For example, when used to monitor the coding process, the downtime alarm and shutdown device monitors the coding system based on the green light signal and can detect when the coding system is paused or stopped while the sorting line is actively sorting, leading to missed codes. Existing technologies can only detect when the coding system is paused while the sorting line is actively sorting, leading to missed codes. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the present invention is further described below through specific embodiments.

[0028] A shutdown alarm device for a repeater of a coding system, comprising a shutdown alarm device, a repeater of the coding system and an audible and visual alarm light, a sorting line PLC, a coil KA1 and a contact switch K1 of relay one, a coil KA2 and a contact switch K2 of relay two, a reset switch SB1, a coil KA3 and a contact switch K3 of relay three, such as Figure 5 As shown, the coil KA1 of relay one is connected in series between the output terminal Q and the common terminal of the sorting line PLC. When the output terminal Q of the sorting line PLC outputs a signal, the coil KA1 of relay one is energized, thereby controlling the closing of the contact switch K1 of relay one. The contact switch K3 of relay three is connected in series between the common terminal of the sorting line PLC and the 24V power supply. The voltage at the common terminal of the sorting line PLC is 0V.

[0029] like Figure 1 and Figure 4 As shown, the repeater signal is connected to the sound and light alarm light, and the coil KA2 of relay 2 is connected in series between the green light line of the sound and light alarm light and the common input terminal of the repeater.

[0030] like Figure 2 As shown, the shutdown alarm device uses a PLC controller, model is Mitsubishi Electric's MELSEC The FX1S-10MR series PLC controller has two COM terminals and one 24V+ terminal. It also has input terminals X000-X005, output terminals Y000-Y004, common output terminals COM0-COM3, L and N terminals, and data registers. The COM terminal and 24V+ terminal can be used as power supplies for sensors. The X000-X005 input terminals can be parameterized as RUN inputs (i.e., when connected or the signal is high), they send a signal to the PLC, indicating that a certain operation or machine can begin running. The coil KA3 of relay three is connected in series between the output terminal Y000 and the 24V+ DC output terminal of the downtime alarm shutdown device. The other COM terminal of the downtime alarm shutdown device is electrically connected to COM0. The COM terminal is equivalent to the negative pole of the DC power supply. A transistor is connected in series between the internal output terminal Y000 and COM0 of the downtime alarm shutdown device. The on and off of the transistor is controlled by the control program built into the downtime alarm shutdown device. When the transistor is turned on, the coil KA3 of relay 3 is energized, thereby controlling the closing of the contact switch K3 of relay 3. The common terminal of the sorting line PLC receives a signal, indicating that the repeater is down.

[0031] The common output terminal COM of the shutdown alarm shutdown device and the input terminals X000, X001, and X002 are respectively connected in series with the contact switch K1 of relay one, the contact switch K2 of relay two, and the reset switch SB1.

[0032] The shutdown alarm device is executed as follows Figure 3 In the control program shown, the shutdown alarm device generates a pulse signal when it is powered on, triggering the data register D0 to be initialized to 0;

[0033] When the output terminal Q of the sorting line PLC outputs 24V (household separation signal), the coil KA1 of relay 1 is energized, thereby controlling the contact switch K1 of relay 1 to close. The input terminal X000 of the shutdown alarm device receives the signal from the common output terminal COM, representing the household separation instruction, and the value of the data register D0 is increased by 1;

[0034] When the green light of the repeater's sound and light alarm lamp is on, the coil KA2 of relay 2 is energized, thereby controlling the contact switch K2 of relay 2 to close. The input terminal X001 of the shutdown alarm shutdown device receives the signal from the common output terminal COM, indicating that the coding system is coding normally, and the value of the data register D0 is reset to 0.

[0035] When the reset switch SB1 is closed, the input terminal X002 of the shutdown alarm device receives the signal from the common output terminal COM, which represents the reset instruction of the coding system and resets the value of the data register to 0;

[0036] Check whether the value of data register D0 is greater than or equal to 2. If so, the internal drive circuit of the shutdown alarm device will supply sufficient current to the base of the transistor between output terminals Y000 and COM0, turning the transistor on. Output terminals Y000 and COM0 are connected, coil KA3 of relay three is energized, contact switch K3 is closed, and the common terminal of the sorting line PLC receives a signal, indicating that the relay is down. If the value of data register D0 is less than 2, the internal drive circuit of the shutdown alarm device will not supply current to the transistor between output terminals Y000 and COM0.

[0037] Therefore, this downtime alarm shutdown device executes as follows Figure 3 When the control program shown in the figure is used, after all cigarettes in the current sorting order have been coded, the repeater's sound and light alarm light will flash yellow and then turn green. At this time, the sorting line PLC will output a household separation signal to the repeater and the downtime alarm shutdown device. Under normal circumstances, the repeater will start coding again after receiving the household separation signal. When the coding of the household order is completed, the sound and light alarm light will flash yellow and then turn green.

[0038] If the repeater fails, the sound and light alarm light will flash yellow and then will not light up green again, but the sorting line PLC will still output the household separation signal to the repeater and the failure alarm shutdown device. In this case, if the failure alarm shutdown device receives two household separation signals in succession but does not receive the green light signal, it will be judged that the repeater has failed, and will immediately output the alarm shutdown signal (Y000) to the sorting line PLC to prevent large quantities of cigarettes from not being coded. After manual confirmation, the reset switch (X002) can be pressed to reset the failure alarm shutdown device.

[0039] After the shutdown alarm system was put into use, the sorting line PLC could immediately issue an alarm and shut down the system when a repeater failed, effectively resolving the issue of batches of cigarette cartons not being coded. It was also found to be effective in resolving the issue of batches of cigarette cartons not being coded while the coding system was not activated while sorting was in progress.

[0040] In addition, the shutdown alarm device of the present invention does not interlock the coding system and the sorting system. Therefore, when the sorting system is debugged and processed separately, the coding system can be shut down, allowing the sorting system to independently run a sorting operation (that is, allowing the sorting line PLC to output two household sorting completion signals). When the sorting system is operated independently, it is not necessary to always keep the repeater's sound and light alarm light green, or the sound and light alarm light yellow for a period of time that does not exceed the threshold.

[0041] The downtime alarm and shutdown device of the present invention provides more accurate signals, eliminates false alarms, and offers greater operational flexibility, convenience, and user-friendliness. For example, when used to monitor the coding process, the downtime alarm and shutdown device monitors the coding system based on the green light signal and can detect when the coding system is paused or stopped while the sorting line is actively sorting, leading to missed codes. Existing technologies can only detect when the coding system is paused while the sorting line is actively sorting, leading to missed codes.
