As shown in fig. 2 and 3, 10 proximity switches are used to detect the integrity of the aluminum foil paper in the cigarette packet, and 5 proximity switches are arranged on two sides of the cigarette packet transmission guide rail respectively and are uniformly arranged according to the size of the cigarette packet, so as to ensure the integrity detection of the aluminum foil paper. The cigarette case adopting the GDX2 packaging machine has the size of 86.45mm in length and 54.4mm in width and 22.5mm in thickness, and the effective detection surface of the adopted sensor is circular and has the diameter of about 11mm after measurement. The cigarette packet is transmitted on the guide rail, the detection starts, and 10 proximity switches respectively detect aluminum foil signals within the range along with the movement of the cigarette packet. Along with the movement of the cigarette packet, the detection signal of the sensor exists until the whole cigarette packet moves out of the detection range, so that the proximity switch outputs a section of fixed pulse signal. And comparing the approach switch signals after the acquisition is finished to obtain the judgment whether the aluminum foil paper has defects. The aluminum foil paper has defects, and the cigarette packet needs to be removed in the subsequent process.
The first fiber optic sensor 40 is mounted in front of the first and second sets of proximity switches 20, 30 and the second fiber optic sensor 50 is mounted behind the first and second sets of proximity switches 20, 30. The transverse horizontal vertical distance from the first optical fiber sensor 40 to the center of the connecting line of the front ends of the first group of proximity switches 20 and the second group of proximity switches 30 is equal to the transverse horizontal vertical distance from the second optical fiber sensor 50 to the center of the connecting line of the rear ends of the first group of proximity switches 20 and the second group of proximity switches 30, and the transverse horizontal vertical distance is equal to the length 86.45mm of one cigarette packet. The cigarette packet starts detection after leaving the first optical fiber sensor 40, and stops detection when approaching the second optical fiber sensor 50.
As shown in fig. 2 and 3, at the beginning of detection, the proximity switch 1 and the proximity switch 2 receive the aluminum foil signal first. And (3) as the cigarette packet moves, the detection signal of the proximity switch exists all the time until the whole cigarette packet moves out of the detection range of the proximity switch 1 and the proximity switch 2. Therefore, the proximity switches 1 and 2 output a fixed pulse signal. Similarly, the pulse width received by the proximity switches 3 and 4 is consistent with the width of the proximity switches 1 and 2, the lag time t =86.45/4/V, and V is the cigarette packet conveying speed. The pulse collected by the proximity switch 5 and the proximity switch 6 lags behind the proximity switch 3 and the proximity switch 4, the pulse collected by the proximity switch 7 and the proximity switch 8 lags behind the proximity switch 5 and the proximity switch 6, and the pulse collected by the proximity switch 9 and the proximity switch 10 lags behind the proximity switch 7 and the proximity switch 8.
After the signal acquisition is completed, only the 10 pulse signals of the first group of proximity switches 20 and the second group of proximity switches 30 are compared. The detected pulse signals have the same width, the lag time meets the requirement, and the pulse signal time corresponding to each two pulse signals is also the same (such as the proximity switch 5 and the proximity switch 6), so that the aluminum foil paper is intact. If the difference is not met, the aluminum foil paper is indicated to be defective, the cigarette packet needs to be removed in the subsequent process, and the controller sends a removal signal to a control system of the packaging machine.
When the controller receives a starting signal, tobacco bale signal judgment is needed, detection signals are realized through the first optical fiber sensor 40, the tobacco bale signal arrives to start the proximity switch signal collection, and the proximity switch collects signals. If no signal is collected by 10 proximity switches and the signal detected by the second optical fiber sensor 50 is up, it indicates that the signal collection by the proximity switches is over. If the proximity switch can smoothly collect signals, the second optical fiber sensor 50 also collects the signals to judge whether the cigarette packet moves out of the collection area. After the moving-out, 10 proximity switches are required to acquire signals and process the signals. And judging whether the defects exist by comparing signals such as amplitude, duration and the like of the acquired pulses. If no signal exists in 10 proximity switches, the aluminum foil paper is absent. If the aluminum foil paper is missing or has defects, the information of the cigarette packets is transmitted to a removing device to be removed, the number of the defective cigarette packets and the number of the normal cigarette packets are recorded, and the processing data of the system can be conveniently acquired. Then the system needs to prepare for the next detection, and the rejection signal is delivered to a rejection device for realization. And monitoring the removed data at any time after power is on, and immediately sending an alarm signal to inform personnel to process if abnormality is found.
In summary, the utility model selects the proximity switch as the detecting element for the integrity of the aluminum foil paper, dynamically detects the integrity of the aluminum foil paper of the cigarette packet by using a plurality of detecting points in the process of packaging the cigarette packet, and determines whether the target cigarette packet has the defect of the aluminum foil paper by processing the detecting signal; meanwhile, the cigarette packet removing machine is connected with a packing machine control system and a workshop management information system through a network, so that defective cigarette packets are removed, the quality of products with different frequencies is mastered at any time, the overall quality of cigarettes is controlled, and the production efficiency and the cigarette packet qualified rate are improved.
