Description

Technical Field

[0001] The present invention relates to the technical field of cigarette package detection, and in particular to a self-inspection reminder system for cigarette package production. Background Art

[0002] Operators of packaging equipment work long hours and have high labor intensity. At the same time, they need to take into account all aspects of equipment operation, so it is inevitable that they will miss self-inspections. Therefore, it is very important to remind operators to conduct self-inspections. The packaging workshop currently uses the timed self-inspection reminder window provided by the MES system. There is a large gap between the timing of reminders and the actual production of the workshop, especially when the equipment is shut down. Since timed reminders are mainly used, even if the equipment is shut down and the operator cannot obtain the cigarette rods for inspection, a reminder will be given. After the equipment has been shut down for a long time, it is impossible to effectively issue a reminder for self-inspections when restarting, which lacks flexibility. Therefore, how to provide self-inspection reminders for cigarette pack production is of great significance. Summary of the invention

[0003] The present invention provides a self-inspection reminder system for cigarette pack production, which solves the problem that the existing cigarette production workshop lacks flexibility in self-inspection reminders to operators, which easily causes untimely self-inspection reminders.

[0034] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0035] Aiming at the problem that the current cigarette production workshop lacks flexibility in self-checking reminders for products during production, the present invention provides a self-checking reminder system for cigarette pack production, which uses a photoelectric coupler to detect cigarette packs transmitted on the production line, and a microprocessor controls the relay to close when the cigarette pack transmission interval is greater than a set time threshold, so that the indicator screen displays a timeout reminder. This solves the problem that the existing cigarette production workshop lacks flexibility in self-checking reminders for operators, which easily leads to untimely self-checking reminders, can better meet the actual production needs of the workshop, and improve the management level of workshop production.

[0036] like Figure 1As shown, a self-checking reminder system for cigarette pack production includes: a microprocessor, a photoelectric coupler, a relay and an indicator screen. The first input end of the microprocessor is connected to the output end of the photoelectric coupler, the first output end of the microprocessor is connected to the control end of the relay, the input end of the relay is connected to the power output end, and the output end of the relay is connected to the input end of the indicator screen. The photoelectric coupler is used to detect whether the production line has conveyed the cigarette pack to the set position, and the microprocessor calculates the cigarette pack conveying interval time according to the detection pulse output by the photoelectric coupler, and controls the relay to close when the cigarette pack conveying interval time is greater than the set time threshold, so that the indicator screen displays a timeout and other cigarette reminder.

[0037] Specifically, the microprocessor calculates the interval time of each cigarette packet transmission based on the pulse signal of the photoelectric coupler detecting the transmitted cigarette packet, and when the interval time exceeds the set time threshold, the indicator screen displays a timeout reminder. Of course, the microprocessor can also count the cigarette packets detected by the photoelectric coupler, and when the count reaches the set value, it reports to the operator to remind him to conduct quality inspection. This system can solve the problem that the existing cigarette production workshop lacks flexibility in self-inspection reminders for operators, which easily leads to untimely self-inspection reminders. It can better meet the actual production needs of the workshop and improve the management level of workshop production.

[0038] The system also includes a counter; the counter is connected to the microprocessor signal, and the counter is used to count cigarette packs according to the detection pulses and display the total count amount.

[0039] In actual applications, the counter is used to count the output of the workstation. The system will record the time of each cigarette rod being taken for testing, and record the output from the last time a cigarette rod was taken to the current time. These two sets of data can provide a reference when quality problems occur, and can also provide an effective quantitative evaluation of the timeliness of the operator's self-inspection.

[0040] The system also includes: a touch screen; the touch screen is connected to the microprocessor signal, the touch screen is used to run the human-computer interaction interface and display the total count in real time. When the total count is greater than the set value, the microprocessor controls the touch screen to display a reminder that the count has been reached.

[0041] The system also includes: a buzzer; the buzzer is connected to the microprocessor signal, and the microprocessor controls the buzzer to sound a reminder when the cigarette packet transmission interval is greater than the set time threshold.

[0042] The system also includes: a signal collector; the signal collector is connected to the microprocessor by signal, and the signal collector is used to collect signals of the operating status of the cigarette packaging machine. When the cigarette packaging machine is operating normally, the microprocessor controls the relay to close, so that the indicator screen displays reminders during the operation of the device.

[0043] Furthermore, the signal collector includes: a voltage sensor and a data acquisition module. The output end of the voltage sensor is connected to the input end of the data acquisition module, and the voltage sensor is used to detect the voltage of the start-stop signal line of the cigarette packaging machine. The data acquisition module performs analog-to-digital conversion on the voltage and determines whether the cigarette packaging machine is in a normal operation state or a stopped state according to the voltage.

[0044] In practical applications, the data acquisition module includes an analog-to-digital conversion module and an acquisition chip. The analog-to-digital conversion module is signal-connected to the acquisition chip. The analog-to-digital conversion module is used to convert the analog voltage value into a digital value and transmit it to the acquisition chip to form a detection pulse.

[0045] The system also includes: a quality inspection confirmation button. The output end of the quality inspection confirmation button is connected to the second input end of the microprocessor. The microprocessor controls the touch screen to display a self-inspection reminder when the photoelectric coupler detects a cigarette pack, and controls the touch screen to stop the self-inspection reminder after the operator presses the quality inspection confirmation button. The microprocessor also controls the relay to close when the quality inspection confirmation button is pressed, so that the indicator screen displays a quality inspection confirmation reminder.

[0046] Furthermore, the indicator screen includes: a red signal screen, a yellow signal screen and a green signal screen; the red signal screen is used to display a quality inspection confirmation reminder, the yellow signal screen is used to display a timeout and smoke reminder, and the green signal screen is used to display a reminder during equipment operation.

[0047] In actual applications, the indicator screen can be implemented with red, yellow and green three-color signal lights. The red signal light can be filled with the words "quality inspection confirmed", the yellow signal light can be filled with the words "timeout waiting for smoke", and the green signal light can be filled with the words "equipment in operation".

[0048] The system also includes: a timer; the timer is connected to the microprocessor signal, and when the cigarette packet starts to be transmitted, the microprocessor sets a time threshold for the timer according to the timing time set on the touch screen and starts timing. When the cigarette packet transmission interval is less than the set time threshold, the microprocessor controls the timer to reset to zero and restart the timing.

[0049] Furthermore, the microprocessor is a Raspberry Pi board. In practical applications, the Raspberry Pi board can be a Raspberry Pi 3B+ development board, and is configured with a microSD card and a shell. After the Python program is written on the computer, it can be transferred to the Raspberry Pi development board to control the peripheral hardware of the system. In one embodiment, Figure 2 As shown, the GPIO input port of the Raspberry Pi board is connected to the signal terminal on the device that is synchronized with the output through a photocoupler, and the GPIO output port of the Raspberry Pi board is connected to the indicator screen and buzzer through a relay. The input of the output signal and the output of the indicator screen, buzzer and other reminder signals are realized, and finally the Raspberry Pi is connected to a 7-inch touch screen as a human-computer interaction interface.

When the interval time between cigarette pack transmissions is greater than the set time threshold, the microprocessor controls the relay to close, so that the indicator screen displays a timeout reminder. This solves the problem that the existing cigarette production workshop lacks flexibility in self-checking reminders for operators, which easily leads to untimely self-checking reminders. It can better meet the actual production needs of the workshop and improve the management level of workshop production.
