[0061] The weight sensor 12 is used to collect the weight information of the cigarette pieces on the conveyor belt in real time and input it into the microprocessor unit 2;

The signal output end of the microprocessor unit 2 is electrically connected to the control ends of the first solenoid valve 31 and the second solenoid valve 32 respectively. The first solenoid valve 31 and the second solenoid valve 32 are respectively installed in the pneumatic control system or the hydraulic control system of the lifting and intercepting smoke mechanism and the rejecting smoke mechanism. In this embodiment, the control ends of the first solenoid valve 31 and the second solenoid valve 32 are both relays.

[0063] The lifting and intercepting smoke mechanism is a lifting roller driven by a pneumatic control system or a hydraulic control system, and the rejecting smoke mechanism is a rejecting push rod driven by a pneumatic control system or a hydraulic control system;

[0064] The rejection in-place detection unit 4 comprises: an in-place detection electric eye 41 and a second imaging device 42 which are electrically connected to the microprocessor unit 2 respectively;

[0065] The in-place detection electric eye 41 is used to detect the in-place of rejected unqualified cigarettes, and send the in-place detection result to the microprocessing unit 2;

[0066] The second imaging device 42 is used to perform secondary collection of double-code information when the in-place detection electric eye 41 detects rejected unqualified cigarettes, and input the secondary collected double-code information into the microprocessing unit 2 for comparison and verification of the double-code information;

[0067] The device further comprises an audible and visual alarm unit 6, which comprises an alarm light 61 and a buzzer 62, and the audible and visual alarm unit 6 is electrically connected to the microprocessing unit 2 and the power supply unit 5 respectively;

[0069] The microprocessor unit 2 detects that the information of the cigarette pieces is missing, the rejection detection unit 4 fails to detect the rejected unqualified cigarette pieces, and the information comparison and verification result of the microprocessor unit 2 does not meet the preset conditions;

[0070] The device further comprises a human-machine interaction unit 7, and the human-machine interaction unit 7 is electrically connected to the microprocessing unit 2 and the power supply unit 5 respectively;

[0071] The human-machine interaction unit 7 is used to display the information of the cigarette pieces on the conveyor belt and the operating status of the device in real time;

[0072] The device further comprises a network switch 8, which is wirelessly connected to the information monitoring unit 1, the microprocessing unit 2 and the rejection detection unit 4 respectively, and is electrically connected to the power supply unit 5;

[0073] The network switch 8 is used to realize wireless communication between the information monitoring unit 1 and the rejection detection unit 4 and the microprocessing unit 2 .

[0074] In the specific implementation process, Figure 3 As shown in the flowchart, when the cigarette pieces on the conveyor belt are delivered to the designated position, the first imaging device 11 of the information monitoring unit 1 collects the double-code information of the cigarette pieces and inputs it into the microprocessing unit 2, wherein the double-code information includes the brand code and the engineering code; the weight sensor 12 collects the weight information of the cigarette pieces and inputs it into the microprocessing unit 2;

[0075] The microprocessing unit 2 receives the information of the cigarette and performs a quality inspection. When the microprocessing unit 2 detects that the double code information of the cigarette is missing, or the weight information does not meet the preset standard value, the cigarette is determined to be an unqualified cigarette. If the double code information of the cigarette is missing, the sound and light alarm unit 6 will be directly triggered to send a sound and light alarm to remind the staff to manually screen out the cigarettes. If the weight of the cigarette is abnormal and unqualified, the microprocessing unit 2 will send a start signal to the interception and rejection control unit 3 to start rejecting the unqualified cigarettes.

[0076] When the relay of the lifting roller in the interception and rejection control unit 3 receives the electrical signal of the microprocessor unit 2, the first electromagnetic valve 31 of the lifting roller will drive the lifting roller to rise and perform the interception action; when the microprocessor unit 2 sends the electrical signal to the relay of the rejection push rod, it will drive the second electromagnetic valve 32 of the rejection push rod to perform the rejection action. In this embodiment, a one-way limit gate is also provided at the end of the rejection push rod, which is a purely mechanical structure and is used to limit the one-way movement of the rejected cigarette pieces; after the above process, the lifting roller rises to intercept the cigarette pieces, and then the rejection push rod starts to move to reject the unqualified cigarette pieces intercepted by the lifting roller, and the rejected unqualified cigarette pieces pass through the one-way limit gate and reach the box retention area (i.e., the detection area of ​​the rejection detection unit 4);

[0077] Afterwards, the in-place detection electric eye 41 in the in-place detection unit 4 is removed. The in-place detection electric eye 41 performs in-place detection on the rejected unqualified cigarettes to determine whether the rejected unqualified cigarettes have correctly arrived at the box retention area, and sends the in-place detection result to the microprocessing unit 2;

[0078] If the in-place detection electric eye 41 does not detect the rejected unqualified cigarettes, it will directly trigger the sound and light alarm unit 6 to send out a sound and light alarm to remind the staff to manually screen out the unqualified cigarettes;

[0079] If the in-place detection electric eye 41 normally detects the rejected unqualified cigarette pieces, the second imaging device 42 will perform a secondary collection of the double-code information of the rejected unqualified cigarette pieces detected by the in-place detection electric eye 41, and input the secondary collected double-code information into the microprocessing unit 2, and perform a comparison and verification of the double-code information. If the comparison and verification results are consistent, the lifting roller in the interception and rejection control unit 3 will fall, stop interception, and the conveyor belt will continue to work normally; if the comparison and verification results are inconsistent, the interception and rejection control unit 3 will still save the start state, and the sound and light alarm unit 6 will sound a sound and light alarm to remind the staff to manually screen out the unqualified cigarette pieces and wait for the manual screening before re-running the device;

[0080] In addition, the device of this embodiment is also provided with a human-machine interaction unit 7, which can display the information of the cigarette pieces on the conveyor belt and the operating status of the device in real time; the human-machine interaction unit 7 includes two working pages, namely, a normal operation interface and an abnormal rejection interface.

[0081] In addition, the device also realizes wireless communication between various devices and the microprocessing unit 2 by setting a network switch 8. The network switch 8 is the central node of the network and can effectively improve the efficiency of internal communication;

[0082] This device is used to give an audible and visual alarm when abnormal weighing or missing double codes appear in finished cigarette boxes at the weighing plate of the conveyor belt, and after a series of interception and rejection actions, the rejected cigarette boxes are detected for rejection and the double code information is verified to ensure that the rejected cigarette boxes are correct; this device can effectively solve the problem of wrong rejection or missed rejection caused by fluctuations in system processing time, failures of the rejection cylinder or air pressure regulating valve, and other human factors when the finished cigarette boxes are to be rejected due to abnormal weighing or missing double codes caused by missing strips during high-speed production, and further avoid the hidden danger of unqualified cigarettes flowing downstream.
