In the process of tobacco processing, the cigarette assembler is usually used in conjunction with the cigarette making machine, and the two are connected to form a cigarette assembler unit through a connecting device. Taking the YJ29 cigarette assembler as an example, the YJ29 cigarette assembler usually includes multiple key parts in structure, such as the filter feeding mechanism, the U-turn output system, the detection drum suction detection cover, the cork paper cutter assembly and the rubber roller assembly. When the YJ29 cigarette assembler is running, the double-long cigarettes after rubbing and connecting are transferred to the rear cutting drum wheel through the removal drum wheel and the elimination drum wheel. The double-long cigarettes are cut into two by the rear cutter to form internal and external exhaust cigarettes, which are transferred to the first separation drum wheel and the second separation drum wheel, and then through the selection drum, the detection drum, the rejection drum, the rear conveying drum, and the large flow device, the finished cigarettes are produced and flow into the next process. When double-length cigarettes pass through the junction of the rear cutting drum and the rear cutter, they will be blocked due to cutter blunting, double-length cigarettes jumping, etc. Since there is no detection and identification device for the blockage here, the machine cannot be automatically shut down. By the time the operator finds the blockage and shuts down the machine, the blockage has already caused serious consequences, such as cutter damage and device deformation.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.
[0022] In the prior art, the YJ29 cigarette receiving and packaging machine is used as an example. When the YJ29 cigarette receiving and packaging machine is in operation, the double-long cigarettes after rubbing and packaging are passed to the rear cutting drum wheel 3 through the removal drum wheel 1 and the elimination drum wheel 2. The double-long cigarettes are cut into two by the rear cutter 5 to form inner and outer exhaust cigarettes, which are passed to the first separation drum wheel 4 and the second separation drum wheel. Then, the finished cigarettes are produced through the selection drum, the detection drum, the rejection drum, the rear conveying drum, and the large flow device to flow into the next process. The YJ29 cigarette receiving and packaging machine in the prior art often has problems such as the elimination drum wheel 2 rejecting the cigarettes, the unstable and disordered handover of the double-long cigarettes, and the passivation of the rear cutter 5 during operation. The utility model proposes a cigarette blockage detection and identification device, which installs high-frequency photoelectric switches at 7 o'clock of the elimination drum 2 and 5 o'clock of the first separation drum 4, accurately detects the number of cigarettes entering and exiting the rear cutting drum 3, and combines synchronous detection pulses, quality controllers, human-machine interface HMI and PLC controllers to achieve effective identification and judgment of cigarette blockage. Once a blockage is detected, the initial blockage and shutdown procedures of the rear cutting drum 3 and the rear cutter 5 are immediately started, thereby greatly improving the quality control capability of the YJ29 cigarette receiving and packaging equipment production.
[0023] The utility model proposes an embodiment of a device for identifying a blocking of a receiving and loading machine. Specifically, Figures 1 to 4 As shown, the receiving machine includes a removal drum 1, an elimination drum 2, a rear cutting drum 3 and a first separation drum 4 which are sequentially connected in transmission, the rear cutting drum 3 is connected with a rear cutter 5, and the blockage identification device includes a photoelectric switch, a synchronous pulse generator, a quality controller and a PLC controller; the output line of the photoelectric switch is connected to the input end of the quality controller, the output end of the synchronous pulse generator is connected to the input end of the quality controller, and the output end of the quality controller is communicatively connected to the PLC controller.
[0024] The utility model provides a blocking identification device for a receiving machine, and a high-frequency reflective photoelectric switch is respectively provided at the northeast direction of the elimination drum 2 and the northwest direction of the first separation drum 4 outside the smoke exhaust branch, and a synchronous pulse signal is set in combination with a synchronous pulse generator and a quality controller. Figure 3 As shown, the rising edge of the cigarette machine blockage detection signal is included in the synchronous pulse signal to detect the number of cigarettes entering and exiting the rear cutting drum 3 respectively. By connecting the detection pulse signal to the quality controller and communicating with the quality controller and the PLC controller, the cigarette blockage identification is accurate, and the initial blockage of double-length cigarettes at the rear cutting drum 3 and the rear cutting knife 5 of the receiving machine is identified, the machine is shut down in time, consumption is reduced, and product quality is improved.
[0025] Specifically, in one embodiment of the present invention, the photoelectric switch includes a first photoelectric switch B1 and a second photoelectric switch B2. The first photoelectric switch B1 is installed at 7 o'clock on the elimination drum 2, and the second photoelectric switch B2 is installed at 5 o'clock on the first separation drum 4. Specifically, Figure 1 and Figure 2 As shown, the double-long cigarettes after rubbing and splicing are passed to the rear-cutting drum 3 through the removal drum 1 and the elimination drum 2. The rear cutter 5 cuts the double-long cigarettes into two, forming inner and outer exhaust cigarettes, which are passed to the first separation drum 4 and the second separation drum. The double-long cigarettes at 7 o'clock of the elimination drum 2 are detected by the first photoelectric switch B1, and the outer exhaust cigarettes at 5 o'clock of the first separation drum 4 are detected by the second photoelectric switch B2. On the one hand, it can facilitate the installation of the first photoelectric switch B1 and the second photoelectric switch B2, and on the other hand, it can more accurately capture the cigarette signals entering and exiting the rear-cutting drum 3.
[0026] In one embodiment of the utility model, the first photoelectric switch B1 and the second photoelectric switch B2 are both high-frequency reflective photoelectric switches. The high-frequency reflective photoelectric switch includes a transmitter, a receiver and a reflective surface. The transmitter emits an infrared beam with a fixed direction and angle. When these rays hit the reflective surface, they are reflected back to the receiver. The receiver detects the reflected rays to determine whether the target object exists. The high-frequency reflective photoelectric switch has a fast response speed and can detect cigarettes moving at high speed. The high-frequency reflective photoelectric switch is easy to install and can adapt to the detection of cigarettes of different materials and shapes. Its detection distance can also be adjusted to meet the needs of different scenarios.
[0027] In one embodiment of the utility model, the quality controller signal is connected to a controller, specifically, the controller is a PLC controller, and the quality controller is used to transmit a cigarette blockage signal to the PLC controller so that the PLC controller performs shutdown control. The PLC controller can accurately detect the initial blockage of the double-length cigarettes between the rear cutting drum wheel 3 and the rear cutting knife 5 of the cigarette loading machine, and shut down the machine in time to avoid serious blockage and damage to the equipment.
[0028] In one embodiment of the utility model, a touch screen is provided on the human-machine interface HMI. When a blockage triggers the machine to stop, the touch screen will display a fault message "rear-cutting drum wheel 3 is blocked".
[0029] In one embodiment of the utility model, the PLC controller is also signal-connected to an alarm device, which includes at least one of the following: an alarm indicator light, an audible and visual alarm, and a buzzer. The PLC controller has a counter and a timer inside, which accumulates the number of blocking signals through the counter, and accumulates the opening time of the alarm light through the timer.
[0030] In one embodiment of the utility model, the quality controller communicates with the human-machine interface HMI and the PLC controller using the PROFIBUS-DP field bus; PROFIBUS-DP supports high-speed transmission, can meet most real-time control and data transmission requirements, and simplifies wiring, providing a feasible solution for realizing comprehensive factory automation and intelligent field equipment.
[0031] In one embodiment of the utility model, the adjustment steps for detecting cigarette blockage of the rear-cutting drum wheel 3 are as follows: the cigarette is transmitted to the position to be detected by the turning wheel, and when the synchronous pulse signal appears, the detection position of the first photoelectric switch and the second photoelectric switch is adjusted so that the detection light spot is aligned with the cigarette position, and then the detection sensitivity of the first photoelectric switch and the second photoelectric switch is adjusted by the sensitivity adjustment knob, so that when the first photoelectric switch and the second photoelectric switch detect the cigarette, the first photoelectric switch and the second photoelectric switch output a high level, and when no cigarette is detected, the first photoelectric switch and the second photoelectric switch output a low level; the quality controller detects and analyzes the number of cigarettes entering and exiting the rear-cutting drum wheel 3 based on the signal output by the photoelectric switch and the synchronous pulse signal, and determines whether cigarette blockage occurs. The quality controller transmits the blockage shutdown signal to the human-machine interface HMI and the PLC controller through the PROFIBUS-DP field bus, so as to realize effective identification and judgment of cigarette blockage. Once a blockage is detected, the initial blockage and shutdown procedures of the rear-cutting drum wheel 3 and the rear cutter 5 are immediately started. The cigarette blockage detection and identification device is easy to use, simple to adjust, and has obvious effects. It can identify the initial blockage of double-length cigarettes at the rear cutting drum 3 and the rear cutting knife 5 of the cigarette loading machine, and can stop the machine in time, reduce consumption, eliminate hidden dangers of malfunctions, and improve product quality.
[0032] The cigarette blockage detection and identification device of the utility model is also applicable to other cigarette loading machines besides the YJ29 cigarette loading machine.
