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 the inner side of the lower platform of the circular knitting machine, and is a fixed structure, which does not move all the time. The lens of the digital image collector is facing the circular cloth cylinder of the circular knitting machine, and the lens of the digital image collector is at a certain distance from the cloth surface of the circular cloth cylinder (the distance of the specific distance depends on the focal length of the lens on the digital image collector) adjusted to a most efficient position), such as figure 1 . According to the continuous rotation of the circular cloth drum in production, the digital image colle...

Abstract

The invention relates to an on-line quality monitoring method of a circular knitting machine based on the computer graphical recognition principle, which adopts a digital image collector which is fixed at the inner side of a machine table below the circular knitting machine, a lens thereof faces a circular cloth tube of the circular knitting machine to take photographs of moving cloth continuously according to a photographing frequency stated in one unit of time, the collected linear or planar array digital pictures are delivered in real time to a main spot processor which is equipped with a standard cloth sample library and a defect library for judging defects of textile; once 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; and the main spot processor is provided with a liquid crystal display and a keyboard, and can be equipped with an external communication interface and an external memory interface. 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 circular knitting machine. It is used for online automatic monitoring of the quality of knitting products of circular knitting machines. It belongs to the technical field of textile machinery. Background technique [0002] In the knitting 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...
