Spinning machine threading method and device

Abstract

The invention provides a spinning-machine threading method and device. The spinning-machine threading method is applied to a spinning machine, and includes the steps that initial to-be-detected imagesof reeds of the spinning machine are obtained, the initial to-be-detected images are processed, to-be-detected images are obtained, and the state of yarn in to-be-fed tooth gaps of the reeds and thestate of yarn in adjacent fed tooth gaps are detected in the image processing process; overlapping degrees between the to-be-detected images and a prestored calibration image are computed, and are compared with the preset overlapping degree range; when yarn does not exist in the to-be-fed tooth gaps, yarn exists in the fed gaps, and the overlapping degrees are in the preset overlapping degree range, threading is directly carried out. Therefore, feeding positions of the reeds are accurately positioned through image detection, accurate threading is achieved, the condition that as the feeding positions of the reeds cannot be accurately positioned, threading is false, and manual intervention must be conducted is avoided, workloads of workers are reduced accordingly, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a threading method and device for a spinning machine. Background technique [0002] The textile industry has been one of the important pillar industries of the country's national economy for a long time. However, due to the impact of the world financial crisis, the textile industry itself is also facing a crisis and needs to constantly improve itself with advanced science and technology. At present, the textile industry largely relies on traditional manual operation, which has low work efficiency and requires a lot of manual input, and the degree of automation needs to be further improved. [0003] The reed is made of special straight steel sheets, which are called reed teeth, and there are gaps between the reed teeth for the warp yarn to pass through. The function of the reed is to determine the distribution density of the warp yarns and the width of the fabric, and beat the w...

Problems solved by technology

[0004] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the embodiments of the present invention is to provide a spinning machine threading method and device, which can use image detection to accurately locate the feeding position of the reed, to achieve accurate threading, and to avoid inaccurate Locating the feeding position of the reed leads to the situation where manual intervention is necessary when threading is wrong, thereby reducing the workload of the staff and improving production efficiency
