Embodiment Construction

[0012] The on-line quality monitoring method of carding, drawing, and roving semi-finished products in spinning production 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 Area array CCD or CMOS sensor is adopted, and the digital image collector is installed and fixed at the outlet of the machines involved in the processes of carding, drawing, and roving in the spinning production process. It is a fixed structure and does not generate movement at all times. . Described digital image acquisition device camera lens faces carding, drawing frame, roving semi-finished product, and digital image acquisition device lens is apart from carding, drawing frame, roving semi-finished product certain distance (the distance of specific distance, according to the focal length of the camera lens on the digital image acquisition device adjusted t...

Abstract

The invention relates to a spinning product on-line quality monitoring method based on the computer graphical recognition principle, which adopts a digital image collector fixedly arranged at a discharge port of a machine relating to a plurality of processes of cotton carding, drawing and roving in the spinning production process, a lens thereof faces the semi-finished products to take photographs of the semi-finished products during cotton carding, drawing and roving 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 library and a defect library for judging defects of the semi-finished products, one a defect is detected, the main spot processor transmits a warning signal or even stops the machine station, and reports the defect type, 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 the semi-finished products 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 for spinning products. It is used to automatically monitor the quality of spinning products on-line, and is mainly suitable for the carding, drawing and roving processes of spinning. It belongs to the technical field of textile machinery. Background technique [0002] In the spinning 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, th...
