[0001] The utility model relates to the technical field of cigarette inspection, and more specifically, to a cigarette end face defect detection system. Background Art

[0002] In the tobacco industry, the emergence of special-shaped packaging equipment provides more choices for cigarette production enterprises, but also brings new difficulties to the quality inspection of cigarette end faces. The die box of special-shaped packaging equipment is different from that of conventional packaging equipment, so the current cigarette end face detection system cannot be universal. Due to the die box design of special-shaped packaging equipment and the use of cigarette grids for cigarette transportation, it is easy to cause wrinkles and scratches on the ignition end face of cigarettes. And the brands produced by special-shaped packaging equipment have higher quality requirements, which puts forward higher requirements for the quality inspection system.

[0026] Techniques, methods, and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and equipment should be regarded as part of the specification.

[0027] The current cigarette end defect detection system compares the tobacco pixel range and tobacco gray scale range corresponding to hollow and loose cigarettes to determine whether there are quality defects such as hollow and loose at the end face of the cigarette to be detected, and cannot achieve the detection of all types of cigarette end faces. The current technical solution has the following disadvantages in measuring cigarette end face defects: it can only detect hollow and loose defects at the cigarette end face and cannot achieve the detection of all types of quality defects at the cigarette end face; it can only implement the rejection of hollow and loose defects and cannot achieve full-platform early warning for functional personnel on mobile terminals, PC terminals, and operators' lower-level machines; it cannot determine the mold box where quality defects occur, thus providing guidance for maintenance personnel to repair faults.

[0028] As Figure 1 shown, an embodiment of the present invention provides a cigarette end defect detection system, which includes: an industrial control computer 1, an industrial camera 1 is connected to the input end of the industrial control computer 1, an image processing and operation workstation computer 4 is connected to the output end of the industrial control computer 1, the image processing and operation workstation computer 4 is connected to a database 5, and the database 5 is connected to an early warning platform 6, where:

[0029] The industrial camera 1 is used to collect images of the cigarette end face;

[0030] The industrial control computer 3 is used to store the images of the cigarette end face and transmit the images of the cigarette end face to the image processing and operation workstation computer 4;

[0031] The image processing and operation workstation computer 4 is used to identify cigarette end face defects according to the images of the cigarette end face to obtain the results of cigarette end face defect types and the positions of defective cigarettes;

[0032] The database 5 is used to store the results of the cigarette end face defect types and the positions of the defective cigarettes, and send the results of the cigarette end face defect types and the positions of the defective cigarettes to the early warning platform 6;

[0033] The early warning platform 6 is used to generate early warning information according to the results of the cigarette end face defect types and the positions of the defective cigarettes.

[0034] Among them, as Figure 2As shown, the industrial camera 1 is arranged on one side of the lower cigarette channel 10 of the cigarette magazine of the die box conveying chain plate 12, and is used to take pictures of the end faces of the cigarettes in the die box 11 when the die box 11 conveyed on the die box conveying chain plate 12 is conveyed to the lower cigarette channel 10 of the cigarette magazine, so as to obtain the cigarette end face image. In a specific implementation, the collected cigarette end face image can be transmitted to the image processing and operation workstation computer 4 through an image transmission system for image processing.

[0035] During operation, the industrial camera 1 collects the cigarette end face image, the industrial control computer 3 obtains the cigarette end face image, and then the image processing and operation workstation computer performs cigarette end face defect recognition to obtain the cigarette end face defect type result and the position of the defective cigarette. When the image processing and operation workstation computer 4 detects a defective image, it will upload the defect result to the database 5, perform comparison and analysis of the defect type and position in the database 5, and report to the warning platform 6 according to the defect statistics result.

[0036] Furthermore, the cigarette end face defect detection system further includes a light source 2, which is connected to the industrial control computer 3 and is used to provide illumination for the industrial camera 1. As Figure 2 shown, the light source 2 is arranged at the front end of the industrial camera 1.

Specifically, the database 5 is connected to the input end of the warning platform 6, and the functional personnel mobile terminal 7, the functional personnel PC terminal 8 and the operator's lower computer 9 are connected to the output end of the warning platform 6. In some embodiments of the present invention, after the database 5 determines the same defect type and defect position, if defective images of the same defect type and the same position continuously appear within a recent period of time (for example, 1 hour), relevant images are extracted for comparison. After the database 5 confirms the similarity, the result is pushed to the warning platform 6, and the warning platform 6 pushes the warning information to the functional personnel mobile terminal 7, the functional personnel PC terminal 8 and the operator's lower computer 9. In addition, according to the statistical information, it can be obtained which die box causes the quality defect, and a prompt message is generated for the maintenance personnel. Moreover, all data is stored in the database for subsequent retrieval of warning information to analyze and judge the cigarette quality and safety.

[0038] The cigarette end defect detection system provided by the embodiment of the present utility model collects the cigarette end images through an industrial camera, and analyzes the cigarette ends through an image processing and operation workstation computer to achieve the detection of all types of quality defects of the cigarette ends, and realizes the on-line detection of the quality of the cigarette ends during the packaging process of cigarettes; it can automatically identify the quality defects of the cigarette ends, can push warning information to functional personnel and operators through a warning platform, and can locate the die box where the defects occur; effectively improves the quality of cigarette products, improves the automation production level of cigarette making and tipping equipment, improves work efficiency, reduces costs, and reduces the labor intensity of manual sampling inspection.
