Problems solved by technology

[0006] In the cigarette pack detection method based on grayscale image recognition technology, about the detection of cigarette pack transparent paper [Zhang Chunyu. Lu Linji. Image detection of abnormal cigarette pack transparent paper packaging. Microcomputer applications. 2004.20(10): 57-59. ] is a method of edge detection using image grayscale. This method is aimed at the detection of transparent paper and cannot be used to detect seal defects of cigarette packs.
In the research on the defect detection method of seal [Yu Fan, Wu Yubin, Cao Danhua. Research on Fast Algorithm for Detection of Cigarette Pack Seal Defect. Computer Age, 2005(10):29-30], although this method is fast and effective, it can only detect the seal The presence or absence of the seal, unable to detect errors such as skew and corners when the seal is pasted
At present, there is no special research on various types of error detection in the detection of cigarette pack seals in China

Embodiment 1

[0065] Apply the present invention to the detection of seal defects in online cigarette package production, and refer to the process flow of the device figure 1 , taking the online production of Dujiang Tobacco as the object of illustration. The cigarette packet packaging device is composed of cigarette packet tin foil packaging, cigarette packet outer packaging, cigarette packet seal sticking, transparent paper packaging, pull strip packaging, cigarette rod packaging and other units. After the packaging of cigarette packs is completed, a camera is installed on the conveyor belt to collect images of cigarette packs, and an acquisition controller is added directly above the conveyor belt as a signal to trigger the shooting of the camera. It will automatically take an image of the cigarette pack on the conveyor belt, such as image 3 shown.

[0066] After obtaining the online cigarette pack image, the image can be processed as figure 2 The image recognition process shown. F...

Embodiment 2

[0070] The invention is applied to the transformation of packaging equipment for Dujiang brand cigarettes in tobacco factories. Increase online cigarette package seal defect detection, increase device process reference figure 1 , the cigarette packaging equipment is imported from Germany Schmidt, such as Figure 10 shown. In order to detect the pasting of the seal on the package of cigarette packs, a visual inspection system is added. Image collection is the basis of image recognition. The principle of image detection and recognition of cigarette packs is as follows: figure 2 shown. Image acquisition is to generate a pulse signal to the cigarette pack on the assembly line through the acquisition controller, which is sent to the image acquisition card by the optical fiber sensor. After receiving the pulse signal, the image acquisition card immediately sends the acquisition signal to the CCD image sensor and the camera completes the acquisition. Cameras, sensors, and PLCs in...

Abstract

The invention discloses a cigarette packet seal defect detecting system based on image identification technology. The cigarette packet seal defect detecting system comprises a camera connected to a cigarette making device, a fiber optic sensor, an optoelectronic switch, a programmable logic controller (PLC), a rejection unit, a detecting computer and a monitor display. An image detection system comprises a cigarette packet acquisition module, a cigarette packet image conversion and transmission module, a cigarette packet processing and identifying module, a logical control module, an on-line detecting and monitoring module, and an unqualified cigarette packet rejection unit module. A rapid cigarette packet seal defect detecting method based on image feature recognition is also provided. The invention provides the defect detecting system and the method which are used for cigarette online production small packet seals and cigarettes factory small packet cigarette making devices, and are based on image identification technology.

Description

technical field [0001] The invention relates to the fields of image recognition and process control, and relates to a quality index detection method for pasting small-label seals on cigarette pack packages on a production line. Background technique [0002] Cigarettes, as a kind of consumer tobacco products, are one of the products with larger and more stable demand in my country. At present, the silk making and coiling of major domestic tobacco manufacturing enterprises are carried out on high-speed assembly lines. The degree of automation of cigarette manufacturing equipment is very high, and the mechanical and electrical control systems are complicated. Substandard products may appear due to various reasons in the production process.[ Wang Zhen, Wen Ping, Wu Tiejun. Research on Image Detection of Cigarette Cartridge Drawing Wire. Journal of Changsha Aviation Vocational and Technical College, 2007,7(3):47-50]. Among them, the unqualified pasting of small label seals on th...
