Embodiment Construction

[0012] The online quality monitoring method of printing and dyeing products based on the principle of computer graphic recognition involved in the present invention adopts a digital image collector, and the digital image collector adopts a linear array CCD or CMOS sensor, or adopts an area array CCD or CMOS sensor. The digital image collector is installed and fixed on a sliding rod above the rollers or cloth rolling rollers in each process of printing and dyeing. The digital image collector can be driven by a motor according to the setting of the program and slide back and forth on the sliding rod. The camera lens of the digital image collector faces the cloth surface of the front end of the roller or the cloth rolling roller, and the lens of the digital image collector is at a certain distance from the roller wheel or the cloth surface of the cloth rolling roller (the distance of the specific distance depends on the distance of the lens on the digital image collector. focus an...

Abstract

The invention relates to an online quality monitoring method of dyed products that is based on the computer graphic identification principle, adopts a digital image collector which is arranged and fixed on a slide rod above a rolling wheel or a cloth roller that are related to each technique in the dyeing, a camera shot side of the camera faces to a cloth surface, uninterrupted photographing of the moving cloth surface is implemented according to the set shooting frequency in unit time and repeated motion speed on the slide rod, and collected digital linear array or area array images are transmitted to an in-site processing host in real time; the in-site processing host is internally arranged with a standard cloth sample library and a defect library and implements fabric defect judgment, once a defect is determined, an alarming signal is emitted and leads the machine to halt, defect type on the fabric piece goods is reported, and concrete defect position is computed and indicated. The online quality monitoring method of the invention can implement the uninterrupted quality inspection of the products during the device running process, judge the product defects and indicate the defect type and the defect position.

Description

technical field [0001] The invention relates to an online quality monitoring method for printing and dyeing products. It is used to automatically monitor the quality of printing and dyeing products online. It belongs to the technical field of textile machinery. Background technique [0002] In the printing and dyeing industry, it is generally subdivided into several major processes: rinsing, dyeing, printing, and post-leveling treatment. In the production process of each process, strict quality inspections are required. The quality inspection of products has always consumed a lot of human resources. The main work content of the front-line production car workers in printing and dyeing enterprises, the most important one is to patrol back and forth on the production site non-stop to prevent the occurrence of defective products. Due to the limited ability of each staff member, they cannot manage too many machines. Therefore, the front-line workers in the printing and dyeing ...
