Yarn Winding Machine Defect Detection Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding machines lack the ability to specify the stage at which yarn defects occur, leading to continued operation in suboptimal conditions and potential damage from abnormalities in the winding unit.
Innovation Solution
A yarn winding machine equipped with multiple winding units, yarn defect detecting sections, and a comparing section that analyzes detection results to differentiate between defects caused by the winding unit and the entire automatic winder, using an information reading device to determine the occurrence cause and notify operators of abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fluff detecting section is arranged in every winding unit to detect yarn defects, then yarn quality inspection capability is improved, but the ability to specify the occurrence cause and stage of defects deteriorates
Solution Approach 1:
The automatic winder is divided into multiple independent winding units (first, second, third winding units), each equipped with its own fluff detecting section. This segmentation allows defect detection to be localized to specific winding units, enabling identification of which unit caused the defect. The comparison section then compares detection results across segments to determine the occurrence stage and cause.
2Productivity
If yarn winding continues without specifying defect causes, then productivity is maintained, but yarn quality and reliability deteriorate
Solution Approach 1:
The comparison section analyzes detection results from multiple winding units and provides feedback about defect patterns and occurrence stages. When defects are detected in specific winding units or patterns indicating winding unit causes, the system can trigger notifications or stoppage commands. This feedback loop enables quality control while maintaining continuous operation only when defects are within acceptable parameters.
3Measurement precision
If multiple fluff detecting sections are installed in each winding unit, then defect detection coverage is improved, but device complexity increases
Solution Approach 1:
Multiple fluff detecting sections installed in different winding units are merged into a unified detection system managed by a single comparison section. The comparison section consolidates data from all detecting sections, performs centralized analysis, and determines defect causes by comparing patterns across units. This merging approach maintains comprehensive detection coverage while avoiding the complexity of multiple independent analysis systems.

AI summary
An automatic winder 10 includes a plurality of winding units 11, a plurality of yarn defect detecting devices 31, and a comparing section 42. The plurality of the winding units 11 forms a package 18 by unwinding a yarn 16 wound around a yarn supplying bobbin 15. Each of the plurality of the yarn defect detecting devices 31 is mounted in each of the plurality of the winding units 11, and detects a yarn defect of the yarn 16 wound by each of the winding units 11. A comparing section 42 compares detection results of the plurality of the yarn defect detecting devices 31. The comparing 42 also calculates a tendency of occurrence of the yarn defect in accordance with the detection results of the plurality of the yarn defect detecting devices 31, and compares the tendency of occurrence with the detection result of the yarn defect detecting device 31.
