Analyzing images to determine the appearance quality of the cigarette 230 is well known to those skilled in the art and will not be described in detail herein.

[0101] The cigarette appearance detection device 190 communicates bidirectionally with the industrial computer 110, is controlled by the industrial computer 110, and works according to the control instructions of the industrial computer 110. At the same time, the cigarette appearance detection device 190 sends the acquired image data of the cigarette 230 to the industrial computer 110 for storage and analysis.

[0102] That is, in this embodiment, the upper and lower surfaces of the cigarette 230 are respectively facing upward through the meshing conveying drum 191 and the flip wheel 192, and the upper and lower surfaces of the cigarette 230 are photographed respectively by the camera, and then the image system in the industrial computer 110 performs image comparison to determine the appearance quality of the cigarette 230.

[0103] In this embodiment, the comprehensive cigarette testing device 1110 performs quality performance testing on the received cigarettes 230 .

[0104] Specifically, in this embodiment, if Figure 2 As shown, the comprehensive cigarette testing device 1110 includes any one or a combination of two or more of the following: a negative pressure detector for detecting the inhalation resistance and air leakage of the cigarette 230, a circumference detector for detecting the circumference of the cigarette 230, and a weighing device for detecting the weight of the cigarette 230.

[0105] The cigarette 230 output by the flip wheel 192 enters the comprehensive cigarette testing device 1110, and the suction resistance and air leakage of the cigarette 230 are tested by the negative pressure detection device, and the circumference of the cigarette 230 is then tested by the circumference detector. The weight of the cigarette 230 can also be tested by the weighing machine, thereby realizing the detection of the weight, suction resistance and diameter of the cigarette 230.

[0106] The specific structures of the negative pressure detector, the circumference detector and the weighing device can adopt any structure of the negative pressure detector, the circumference detector and the weighing device in the prior art, and will not be described in detail in this embodiment.

[0107] The cigarettes 230 inspected by the online cigarette appearance quality defect inspection system 100 are recycled into the recycling module 300 .

[0108] In addition, in order to highlight the innovative part of the present invention, technical features that are not closely related to solving the technical problems proposed by the present invention are not introduced in this embodiment, but this does not mean that there are no other structural and functional features in this embodiment.

[0109] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0110] In order to enable those skilled in the art to further understand the online system 100 for detecting full appearance quality defects of cigarettes in this embodiment, the working process of the online system 100 for detecting full appearance quality defects of cigarettes in this embodiment is described below.

[0111] The cigarette overall appearance quality defect online inspection system 100 is divided into two states during use: manual state and automatic state:

[0112] A. When in automatic mode: by collecting the number of carton cigarettes 210 or cigarette sticks 230 produced by the machine online, the required frequency of random inspection is set. When the number of carton cigarettes 210 or cigarette sticks 230 produced meets the required set value, the online cigarette appearance quality defect detection system 100 is triggered to start the detection work. The automatic sampling device 120 connected to the cigarette carton lifting mechanism of the equipment automatically samples the carton cigarettes 210 online, and enters the carton appearance detection device 130 through the action of the conveyor belt to detect the six surfaces of the carton appearance (the data of the detection results is saved, and an alarm or shutdown can be issued if a problem is found). When the signal of the completion of the carton appearance detection is triggered, the conveyor belt works to transport the carton cigarettes 210 to the carton stripping device 140, and the carton is automatically stripped in the carton stripping device 140 through a mechanical structure. After the stripping is completed, the small packets are fed into the small packet appearance detection device 160 in combination with the belt, and the number of small packets of cigarettes 220 in the carton 210 is counted by the small packet number detection device 150, and the statistical results are saved as data. If a problem is found, an alarm or shutdown can be issued. Then, the small packet appearance detection device 160 will complete the inspection of the six surfaces of the small packet appearance (the inspection results are saved as data, and an alarm or shutdown can be issued if a problem is found). After the small packet appearance inspection is completed, the small packet of cigarettes is transported to the small packet unpacking device 170 by the conveyor belt, and the small packet is automatically unpacked in the small packet unpacking device 170 through a mechanical structure. After unpacking, the cigarettes 230 are discharged in a complete and orderly manner on the conveyor belt through the negative pressure and the suction cup. When the sensor on the conveyor belt detects the signal of the cigarette 230, the conveying drum 191 and the flip wheel 192 of the cigarette appearance detection device 190 start to work. The cigarette counter 180 on the conveyor belt counts the number of small packages of cigarettes 230 during the process of conveying the cigarettes 230 by the belt (the detection results are saved, and an alarm or interlock host equipment shutdown can be performed if problems are found). At this time, during the handover process of the cigarette 230 between the conveying drum 191 and the flip wheel 192, the camera detects 180 degrees of the front and back surfaces of the cigarette 230 respectively, completing the detection of the full appearance of the cigarette 230 (the detection results are saved). After the test is completed, the cigarette 230 is transmitted to the cigarette comprehensive testing device 1110 via a conveyor belt, and the final weight, draw resistance and diameter of the cigarette 230 are measured. Finally, the industrial computer 110 automatically saves all the data locally, and can also be directly uploaded to the terminal device of the corresponding department.

[0113] B. In manual mode: the automatic sampling device 120 stops working, and the working process of other devices is the same as that in automatic mode. Except for the case where the sampling of the cigarette carton 210 becomes manual, the other entire control process is the same as that in automatic mode.

[0114] In summary, the online inspection system for the overall appearance quality defects of cigarettes of the present invention can automatically and continuously inspect the appearance of the carton, the number of small packages, the appearance of small packages, the number of cigarettes in small packages, the appearance of cigarettes, the weight, draw resistance, diameter, etc. of cigarettes, thereby reducing the randomness and labor intensity of manual sampling and improving the requirements for the quality control index of cigarette production process. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0115] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
