Description
Technical Field
The invention relates to the field of cigarette detection, in particular to detection equipment for detecting cigarette quality based on machine vision and a cigarette making machine thereof.
Background
The cigarette appearance specifically refers to a cigarette rod except for the end face of the filter tip end and the end face of the lighting end of the cigarette; the hollow end of the cigarette refers to a hollow recess with a certain area and depth formed by unfilled tobacco on the end of the cigarette. The appearance and the cigarette loose end are important quality indexes of cigarettes, although the cigarette loose end does not affect smoking, a consumer can visually perceive the defect and then generate bad impression on corresponding cigarette brands, and therefore the effort of cigarette enterprises for brand construction can be offset. The lack of a filter tip in a cigarette refers to the lack of a filter tip, which is a significant drawback.
Traditional cigarette filter tip terminal surface detects and rejects and go on in the packet diaphragm capsule, can carry out recovery processing as the incomplete cigarette with all 20 cigarettes of rejection when having a cigarette to empty in the packet diaphragm capsule, causes very big waste, and a large amount of cigarettes that are rejected will be retrieved by the manual work, have also increased staff's work load. In order to solve the problem, an infrared photoelectric sensor is adopted as a detection element to detect whether the cigarette is empty and lacks a filter tip on the cigarette making machine, specifically, an optical signal reflected from the tobacco shred end is converted into an electric signal, and whether the current cigarette is empty and lacks a filter tip is judged according to the electric signal. The method for detecting by adopting the infrared photoelectric sensor can cause false picking if the cigarettes are different from the sensor in distance, and the method has no intuition, so that the picked cigarettes are inevitably empty cigarettes due to the action of external force, and whether the picked cigarettes are empty or not cannot be known. And the photoelectric loose-head detector needs to be cleaned frequently, and the photoelectric tube runs for a long time and has attenuation of different degrees, so that the detection is inaccurate. Besides the defects of the missing mouth and the empty head of the cigarette, other defects also need to be detected, and the device for comprehensively detecting the end face of the filter tip and the end face of the ignition end of the cigarette does not exist at present. There is also a trend towards the use of machine vision techniques to detect the appearance of cigarettes.
Therefore, the invention provides the cigarette quality detection device based on machine vision detection, which has the advantages of reasonable structure and high detection efficiency, and can detect the appearance and the end face of the cigarette.

In addition, the cigarettes of many brands can be printed with unique characters (embossed seal numbers) and images (embossed seals) which reflect brand culture at the same time, so that the brand culture can be reflected in each cigarette, brand influence, symbolism and the like are fully improved, and particularly, the brand propaganda function of the cigarette embossed seals is particularly important for high-end brand cigarettes; in the production process of the cigarette steel seal, the printing defects of the steel seal sometimes occur, and the printing defects comprise the problems of steel seal missing, wrong brands of the steel seal, steel seal position deviation, blurred images or characters of the steel seal, steel seal stains and the like; if the cigarettes with the problems flow into the market, the brand image of the cigarettes is affected, so the steel seal detection is very necessary before the cigarette paper 9 wraps the cut tobacco. Therefore, referring to fig. 9, the detection apparatus of the present embodiment further comprises a steel seal detection device comprising a fourth camera assembly 8 comprising a light source 3 for illuminating the steel seal and a camera for capturing an image of the steel seal on the cigarette paper. The quality detection equipment not only can effectively detect the loose ends and the missing mouths of the end faces of the cigarettes, but also can simultaneously detect other end face defects and cigarette appearance defects, adopts a camera to collect single-end-face images or double-end-face images of the cigarettes on the conveying drum wheel 4 in a photographing mode, and can effectively detect and eliminate cigarettes with defective end face appearances, such as filter loss, filter deformation, filter inner hole unclean, filter inner hole deformation, filter side wall holes, loose tipping paper wrapping untight, tobacco loss, tobacco expansion, tobacco end cutting failure and the like, by analyzing and judging photographed images, thereby meeting the requirements of cigarette enterprises on end face detection. Meanwhile, the device has good compatibility and also has a good detection effect on the non-hollow filter tip. The method is very helpful for improving the quality of finished cigarettes. The detection equipment for detecting the cigarette quality based on machine vision can be used for detecting the traditional cigarette and can also be used for detecting the cigarette which is not burnt when being heated, and when the cigarette which is not burnt is detected, the ignition end refers to the heating end.
Specifically, two cameras may be arranged in the first camera assembly 1 to respectively image each end face of the cigarette, or one camera may be arranged to image each end face of the cigarette more than once (including once). In regard to the preferred embodiment of the appearance detection, the second camera assembly 6 and the third camera assembly 7 respectively comprise two cameras, the two cameras are used for respectively imaging each side surface of the cigarette, and the included angle between the image acquisition directions of the two cameras on the same side surface of the cigarette is less than 75 degrees; or the second 6 and third 7 camera assemblies each comprise a camera for imaging more than once (including once) each side of the cigarette.

Each camera assembly collects two images of any side face of each cigarette, each camera assembly is provided with two adjacent cameras which are close to each other, the images of the same cigarette are collected in sequence in a very short time, and then the two images are combined into a picture. This is done to distinguish whether a defect or spray is present and to avoid false detection. During the cigarette production process, some loose tobacco foam falls off and splashes around. When the spray is between the camera and the cigarette, the single view of one picture cannot distinguish. However, the movement speed of the droplets is not basically consistent with the movement speed of the object driven by the cigarette machine, so that the droplets and the defects can be distinguished by the position change of the stains in two images with time difference. On the other hand, the position of the two cameras is different when the droplets are between the cameras and the cigarette, and the position of the droplets projected on the cigarette is also changed. The included angle between the image acquisition directions of the two cameras on the same side of the cigarette is limited to be less than 75 degrees, the two cameras can be combined in a shell and then can be conveniently installed in a limited space formed between the drums, images shot by the two cameras have enough overlap ratio for distinguishing sundries or droplets, and false detection is avoided; and enough full cigarette images can be obtained.
