Furthermore, in order to highlight the innovative part of the present invention, the technical features that are not so closely related to solve the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that there are no other structural and functional features present in the present embodiment.
It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
In order to further understand the cigarette full appearance quality defect online detection system 100 in the present embodiment, the following describes the operation of the cigarette full appearance quality defect online detection system 100 in the present embodiment.
The cigarette full-appearance quality defect online detection system 100 is divided into a manual state and an automatic state in the use process:
A. when in the automatic state: the required sampling frequency is set according to the number of the cigarette carton 210 or the number of the cigarettes 230 produced by the online collecting machine, and when the number of the cigarette carton 210 or the cigarettes 230 produced meets the required set value, the cigarette full-appearance quality defect online detection system 100 is triggered to start detection. The automatic sampling device 120 connected with the cigarette carton lifting mechanism automatically samples the online cigarette carton 210, and the online cigarette carton 210 enters the cigarette carton appearance detection device 130 through the action of the conveying belt to detect 6 surfaces of the cigarette carton appearance (data is stored on the detection result, and an alarm or a stop can be performed when a problem is found). When the signal of the completion of the detection of the appearance of the carton is triggered, the operation of the conveyor belt conveys the cigarettes 210 into the carton stripping device 140, and the carton stripping device 140 automatically strips the carton by a mechanical structure. After the strip is removed, in the process of conveying the small packets into the small packet appearance detection device 160 by combining the belt, the small packet quantity detection device 150 counts the quantity of the small packets of cigarettes 220 of the strip box cigarettes 210, the counted result is stored, and an alarm or a shutdown can be performed when a problem is found. Then, the packet appearance detection device 160 will complete the detection of 6 faces of the packet appearance (data is saved for the detection result, and an alarm or a halt can be performed when a problem is found). After the packet appearance detection is completed, the packet cigarettes are conveyed to the packet unpacking device 170 through the conveying belt, and the packet is automatically unpacked in the packet unpacking device 170 through a mechanical structure. After unpacking, the cigarettes 230 are completely and orderly arranged in the conveying belt through the action of negative pressure and the sucking discs, when a sensor on the conveying belt detects a signal of the cigarettes 230, a conveying drum wheel 191 and a turnover wheel 192 of the cigarette appearance detection device 190 start to work, and the cigarettes 230 are counted in the process of conveying the cigarettes 230 by the belt through a cigarette counter 180 on the conveying belt (data storage is carried out on the detected result, and alarm can be carried out or the interlocking host machine equipment can be shut down when a problem is found). At this time, in the process of handing over the cigarettes 230 between the conveying drum 191 and the turning wheel 192, the cameras respectively detect 180 degrees of the front and back surfaces of the cigarettes 230, and the detection of the full appearance of the cigarettes 230 (the storage of data of the detected results) is completed. After the detection is finished, the cigarettes 230 are transmitted to the comprehensive cigarette testing device 1110 through the conveying belt, the cigarettes 230 are measured for the final weight, the suction resistance and the diameter, and finally the industrial personal computer 110 automatically stores all data locally and can also directly upload the data to terminal equipment of a corresponding department.
B. When in the manual state: the automatic sampling device 120 stops working and the other devices work in the same way as in the automatic state. The entire control flow is the same as in the automatic state except that the sampling of the cigarette carton 210 is changed to manual.
In conclusion, the cigarette full-appearance quality defect online detection system can automatically and continuously detect the appearance of a barrel, the number of small packets, the appearance of small packets, the number of small-packet cigarettes, the appearance of cigarettes, the weight, the suction resistance, the diameter and the like, reduces the randomness and the labor intensity of manual sampling inspection, and improves the requirement of cigarette process quality clearance indexes. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
