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.

Example Embodiment

[0064] Example 1

[0065] The invention is applied to the detection of defects in the seals of online cigarette pack production, and the device process flow refers to figure 1 , Using the online production of Dujiangyan as the object of illustration. The cigarette pack packaging device is composed of cigarette pack tin foil packaging, cigarette pack outer packaging, cigarette pack seal sticking, transparent paper packaging, strip packaging, cigarette stick packaging and other units. After the package is packaged, a camera is installed on the conveyor belt to collect the image of the cigarette package. A collection controller is added directly above the conveyor belt as a signal that triggers the shooting of the camera. The optical fiber sensor is used to transmit to the capture card for collection, so that each pack of cigarettes passes through. Will automatically take a picture of the cigarette pack on the conveyor belt, such as image 3 Shown.

Example Embodiment

[0069] Example 2

[0070] The invention is applied to the transformation of Dujiang brand cigarette packaging equipment in a tobacco factory. Add online cigarette pack seal defect detection and increase device process flow reference figure 1 , Cigarette packaging equipment is imported from German Simude, such as Picture 10 Shown. In order to detect the sticking of the seal on the package of cigarettes, a visual inspection system is added. The collection of images is the basis of image recognition. figure 2 Shown. Image acquisition is to generate pulse signals from the cigarette packs on the assembly line through the acquisition controller, which are sent to the image acquisition card by the optical fiber sensor. After receiving the pulse signals, the image acquisition card immediately sends the acquisition signal to the CCD image sensor and the camera completes the acquisition. The cameras, sensors, and PLCs in the equipment transformation in this project are all Japanese KEYE...

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...
