Description

Technical Field

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

[0002] In the modern cigarette sales process, sorting to households is achieved by a sorting system, and coding is carried out using a coding system. The order information to be coded is stored inside a coding industrial computer, and the coding order information is generated in a specified sequence according to the order. In the sorting link, goods are sorted according to the order. In principle, each order is coded with its exclusive barcode. In the overall operation process, the repeater is responsible for receiving and distributing the information to be coded, and realizing the centralized and unified scheduling function of the coding information.

[0003] As Figure 1 shown, the coding system includes: a repeater, a coding detection sensor, a coding industrial computer, a coder, and an audible and visual alarm lamp. The repeater is cooperatively connected with the coding detection sensor, the coding industrial computer, the coder, and the audible and visual alarm lamp. When the coding detection sensor detects the goods, the signal triggers the repeater. The repeater requests the coding information to be coded from the coding industrial computer in real time and distributes the received information to the coder. The received coding signal communicates with the serial port COM3 of the coding industrial computer through the serial port COM1, and the distributed coding signal is realized between the COM2 and the serial port COM4 of the coder. After all the internal information of each order is coded, before the household switching signal is completed, the repeater will output a signal to the terminal to make the yellow lamp light up to indicate the household switching waiting state. After the repeater receives the household switching signal, it triggers the coding industrial computer to judge whether the current order has been distributed. If all have been distributed, it will switch to the next order. If there is still undistributed information in the current order, the order switching will not be realized at this time. After the repeater sends a coding request message to the coding industrial computer, it will not be able to receive the coding information. At this time, the repeater will output an alarm signal through the terminal to prompt manual fault handling. After the manual service is faulty, the order is switched manually to realize the order switching and the review and verification of the coding information, effectively ensuring the accuracy of the coding information.

[0004] When the coding system gives an alarm by itself, the red light is on. When in the pause and stop states, the yellow light is on. When coding normally, the green light is on. After all the cigarette cartons in the current sorting order are coded, the audible and visual alarm light connected to the repeater will flash yellow and then turn green. At this time, the sorting line will output a household separation signal to the repeater. Under normal circumstances, after receiving the household separation signal, the repeater will start coding again. When the coding of the order for this household is completed, the audible and visual alarm light will flash yellow and then turn green again. If the repeater crashes, the audible and visual alarm light will flash yellow but will not turn green again. However, the sorting line will still output the household separation signal to the repeater. The crash of the repeater causes the cigarette cartons not to be coded in the coding system, and at the same time, the sorting line does not give an alarm and stop. When the abnormality is discovered, a large number of cigarette cartons have not been coded. After the above situation occurs, it is necessary to manually open the cigarette wrapping film again and place the cigarette cartons on the coding belt for manual coding, which is inefficient, time-consuming, and labor-intensive, seriously affecting the cigarette sorting work. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device that uses the signal of the audible and visual alarm light of the coding system and the household separation signal of the sorting system to realize the automatic stop of the sorting system and the separate stop of the coding system by means of a crash alarm and stop device, but the sorting system is debugged and operated.

[0006] A crash alarm and stop device for a repeater of a coding system, including a crash alarm and stop device, a repeater of the coding system, an audible and visual alarm light, and a sorting line PLC; A coil KA1 of a first relay is connected in series between the output terminal Q and the common terminal of the sorting line PLC, and a contact switch K3 of a third relay is connected in series between the power supply and the common terminal of the sorting line PLC; the repeater is signal-connected to the audible and visual alarm light, and a coil KA2 of a second relay is connected in series between the green wire of the audible and visual alarm light and the common input terminal of the repeater; The crash alarm and stop device selects a PLC controller, which has two COM terminals and one 24V+ terminal, and also has at least input terminals X000~X002, output terminal Y000, a common terminal COM0 of the output terminal, L and N terminals, and data registers; a coil KA3 of a third relay 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 internal output terminal Y000 and COM0 of the crash alarm and stop device, and the other COM terminal is respectively connected in series with a contact switch K1 of a first relay, a contact switch K2 of a second relay, and a reset switch SB1 between the input terminals X000, X001, and X002; According to the built-in control program, when the input terminal X000 of the crash alarm and stop device receives signals continuously twice and the input terminals X001 and X002 do not receive signals, it is determined that the repeater has crashed, and the internal drive circuit of the crash alarm and stop device makes the transistor conduct.

[0007] When the input terminal X000 of the downtime alarm shutdown device receives signals continuously for 2 times and the input terminal X001 or X002 receives a signal, it is determined that the repeater is normal.

[0008] The downtime alarm shutdown device performs the following operations according to the built-in control program: When the downtime alarm shutdown device is powered on, it generates a pulse signal to trigger the data register to be initialized to 0; When the output terminal Q of the sorting line PLC outputs 24v, the coil KA1 of the first relay is energized, thereby controlling the contact switch K1 of the first relay to close. The input terminal X000 of the downtime alarm shutdown device receives the signal from the common output terminal COM, and the value of the data register is incremented by 1; When the green light of the audible and visual alarm lamp of the repeater is on, the coil KA2 of the second relay is energized, thereby controlling the contact switch K2 of the second relay to close. The input terminal X001 of the downtime alarm shutdown device receives the signal from the common output terminal COM, and the value of the data register is reset to 0; When the reset switch SB1 is closed, the input terminal X002 of the downtime alarm shutdown device receives the signal from the common output terminal COM, and the value of the data register is reset to 0; When the value of the data register is greater than or equal to 2, the internal drive circuit of the downtime alarm shutdown device conducts the transistor, the coil KA3 of the third relay is energized, the contact switch K3 of the third relay is closed, and the common terminal of the sorting line PLC receives the signal, indicating that the repeater has downtime. When the value of the data register is less than 2, the internal drive circuit of the downtime alarm shutdown device does not conduct the transistor.

[0009] The downtime alarm shutdown device selects a MELSEC FX1S-10MR series PLC controller.

[0010] The base of the transistor is electrically connected to the internal drive circuit of the downtime alarm shutdown device.

[0011] After the downtime alarm shutdown device of the present invention is put into use, when the repeater has downtime, the sorting line PLC can alarm and stop in time, effectively solving the problem of batch cigarette bars not being coded caused thereby. At the same time, it is also found in the application that it can solve the problem of batch cigarette bars not being coded caused by the cigarette bar coding system not starting to code while sorting is in progress.

[0012] In addition, the downtime alarm shutdown device of the present invention does not interlock the coding system and the sorting system. Therefore, when debugging the sorting system alone, it is allowed to turn off the coding system, enable the sorting system to run a sorting operation independently (that is, allow the sorting line PLC to output two signals indicating the completion of household separation), and when the sorting system runs independently, it is not necessary to always keep the green light of the audible and visual alarm lamp of the repeater on, or the time when the yellow light of the audible and visual alarm lamp is on does not exceed the threshold.

[0013] The signal of the downtime alarm and stop device of the present invention is more accurate, without false alarms, and has good job flexibility, being more convenient and user-friendly. When used for monitoring the coding process, the downtime alarm and stop device monitors the coding system according to the green light signal, and can detect the state of missing codes caused by the coding system pausing or stopping while the sorting line is sorting, while the prior art can only detect the state of missing codes caused by the coding system pausing while the sorting line is sorting.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The technical solution of the present invention will be further described below through specific embodiments.

[0016] A downtime alarm and stop device for a repeater of a coding system includes a downtime alarm and stop device, a repeater of the coding system, an audible and visual alarm light, a sorting line PLC, a coil KA1 and a contact switch K1 of a first relay, a coil KA2 and a contact switch K2 of a second relay, a reset switch SB1, and a coil KA3 and a contact switch K3 of a third relay. As Figure 5 shown, a coil KA1 of a first relay 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 the first relay is energized, thereby controlling the contact switch K1 of the first relay to close. A contact switch K3 of a third relay is connected in series between the common terminal of the sorting line PLC and the 24V power supply. The voltage of the common terminal of the sorting line PLC is 0V.

[0017] As Figure 1 and Figure 4 shown, the repeater is signal-connected to the audible and visual alarm light, and a coil KA2 of a second relay is connected in series between the green light wire of the audible and visual alarm light and the common input terminal of the repeater.

[0018] As Figure 2As shown in the figure, the downtime alarm shutdown device selects a PLC controller, which is the MELSEC FX1S-10MR series PLC controller of Mitsubishi Electric. It has two COM terminals and one 24V+ terminal, and also has input terminals X000~X005, output terminals Y000~Y004, common terminals COM0~COM3 of the output end, L and N terminals, data registers. The COM terminal and the 24V+ terminal can be used as a power supply for sensors. When the input terminals X000~X005 are set with parameters to be RUN inputs (i.e., turned on or the signal is high level), it will send a signal to the PLC, indicating that an operation or machine can start running); between the output terminal Y000 of the downtime alarm shutdown device and the 24V+ DC output terminal, the coil KA3 of relay three is connected in series. Another 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. Between the internal output terminal Y000 and COM0 of the downtime alarm shutdown device, a transistor is connected in series. The on and off of the transistor are controlled by the control program built into the downtime alarm shutdown device. When the transistor is turned on, the coil KA3 of relay three is attracted, thereby controlling the contact switch K3 of relay three to close. When the common terminal of the sorting line PLC receives a signal, it indicates that the repeater has a downtime.

[0019] Between the common output terminal COM of the downtime alarm shutdown device and the input terminals X000, X001, and X002, the contact switches K1 of relay one, the contact switch K2 of relay two, and the reset switch SB1 are connected in series respectively.

[0020] The downtime alarm shutdown device executes the control program as Figure 3 shown. When the downtime alarm shutdown device is powered on, it generates a pulse signal to trigger the data register D0 to be initialized to 0; When the output terminal Q of the sorting line PLC outputs 24v (household signal), the coil KA1 of relay one is attracted, thereby controlling the contact switch K1 of relay one to close. The input terminal X000 of the downtime alarm shutdown device receives the signal from the common output terminal COM, representing the household instruction, and adds 1 to the value of the data register D0; When the green light of the audible and visual alarm lamp of the repeater is on, the coil KA2 of relay two is attracted, thereby controlling the contact switch K2 of relay two to close. The input terminal X001 of the downtime alarm shutdown device receives the signal from the common output terminal COM, representing the normal coding instruction of the coding system, and resets the value of the data register D0 to 0; When the reset switch SB1 is closed, the input terminal X002 of the downtime alarm shutdown device receives the signal from the common output terminal COM, representing the reset instruction of the coding system, and resets the value of the data register to 0; Check whether the value of data register D0 is greater than or equal to 2. If the value of data register D0 is greater than or equal to 2, the internal drive circuit of the downtime alarm and shutdown device will supply sufficient current to the base of the transistor between output terminal Y000 and COM0, causing the transistor to conduct, connecting output terminal Y000 and COM0, attracting the coil KA3 of relay three, closing the contact switch K3, and the common terminal of the sorting line PLC receiving the signal, indicating that the repeater has downtime. When the value of data register D0 is less than 2, the internal drive circuit of the downtime alarm and shutdown device will not supply current to the transistor between output terminal Y000 and COM0.

[0021] Therefore, when this downtime alarm and shutdown device executes the control program as Figure 3 shown. After all the cigarettes in the current sorting order are coded, the audible and visual alarm light of the repeater 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 and shutdown device. Under normal circumstances, after receiving the household separation signal, the repeater will start coding again. When the coding of this household order is completed, the audible and visual alarm light will flash yellow and then turn green again; If the repeater has downtime, the audible and visual alarm light will flash yellow but will not turn green again. However, the sorting line PLC will still output the household separation signal to the repeater and the downtime alarm and shutdown device. In this case, if the downtime alarm and shutdown device continuously receives 2 household separation signals but does not receive the green light signal, it is determined that the repeater has downtime, and an alarm and shutdown signal (Y000) will be immediately output to the sorting line PLC to prevent a large number of cigarettes from not being coded. After manual confirmation is correct, the downtime alarm and shutdown device can be reset by pressing the reset switch (X002).

[0022] After this downtime alarm and shutdown device is put into use, when the repeater has downtime, the sorting line PLC can alarm and stop in time, effectively solving the problem of a large number of cigarettes not being coded caused thereby. At the same time, it is also found in the application that it can solve the problem of a large number of cigarettes not being coded caused by the cigarette coding system not starting coding while sorting is in progress.

[0023] In addition, the downtime alarm and shutdown device of the present invention does not interlock the coding system and the sorting system. Therefore, when debugging the sorting system alone, it is allowed to turn off the coding system, enabling the sorting system to independently run a sorting operation once (that is, allowing the sorting line PLC to output two signals indicating the completion of household separation), and when the sorting system is running independently, it is not necessary to always keep the green light of the audible and visual alarm light of the repeater on, or the time when the audible and visual alarm light flashes yellow does not exceed the threshold.

[0024] The signal of the downtime alarm and shutdown device of the present invention is more accurate, without false alarms, and has good operational flexibility, being more convenient and user-friendly. When used for monitoring the coding process, the downtime alarm and shutdown device monitors the coding system according to the green light signal, and can detect the state of missing codes caused by the suspension or stop of the coding system while the sorting line is sorting, while the prior art can only detect the state of missing codes caused by the suspension of the coding system while the sorting line is sorting.
