Embodiment Construction

[0011] The online quality monitoring method of circular knitting machines based on the principle of computer graphic recognition involved in the present invention adopts a digital image acquisition device, which 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 cloth rolling roller of the air-jet loom. 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 lens of the image collector faces the cloth surface at the front end of the cloth rolling roller, and the lens of the digital image collector is at a certain distance from the cloth surface of the cloth rolling roller (the specific distance is adjusted to the most effective position according to the focal length of the lens on the digital image collector ),Figure 1. According to the continuous scrolling of the cloth rolling rol...

Abstract

The invention relates to a textile machine on-line quality monitoring method based on the computer graphical recognition principle, which adopts a digital image collector fixed on a sliding rod above a textile machine cloth roller, a lens thereof faces a cloth cover to take photographs of moving cloth continuously according to a photographing frequency stated in one unit of time and the reciprocating motion speed on the sliding rod, the collected linear or planar array digital pictures are delivered in real time to a main spot processor which is equipped with a standard fabric library and a defect library for judging defects of textile, one a defect is detected, the main spot processor transmits a warning signal or even stops the machine table, and reports the defect type of the cloth, calculates and indicates the specific location where the defect occurs. The on-line quality monitoring method can be adopted to conduct non-stop inspection of product quality in the running process of equipment, so as to judge defects of products and indicate the defect types and locations of defects.

Description

technical field [0001] The invention relates to an online quality monitoring method of a textile loom. It is used to automatically monitor the quality of weaving products on textile looms. It belongs to the technical field of textile machinery. Background technique [0002] In the weaving industry, the quality inspection of products has always consumed a lot of human resources. The main work content of front-line production operators in textile enterprises, the most important one is to patrol the production site continuously to prevent the occurrence of defective products. Due to the limited ability of each staff member, they cannot manage too many machines. Therefore, not only are there a large number of front-line locomotive workers in textile mills, but they are also known for their harsh working environment and high labor intensity. Even so, no matter how skilled the textile workers are, they will still produce a certain amount of defective textile products. In addit...
