Yarn Information Acquiring Device for Winding Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In yarn winding machines, identifying the cause of events occurring in packages formed after the winding process is challenging due to the lack of detailed yarn information acquired at regular intervals.
Innovation Solution
A yarn information acquiring device that manages and stores yarn information on a package-by-package basis, dividing the fully wound yarn length into segments of varying lengths to efficiently utilize memory and acquire temporal changes in yarn information, including tension, thickness, environmental, and operating conditions, allowing for visualization of changes and analysis of event causes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If yarn information is acquired at regular time intervals, then the device complexity is reduced, but the ability to identify event causes is insufficient
Solution Approach 1:
The patent segments the yarn information data by dividing it into multiple time periods (first time period, second time period, etc.) and stores each segment separately with its corresponding package ID and time period identifiers. This segmentation allows detailed temporal analysis of yarn information without requiring continuous high-frequency data collection throughout the entire winding process, thus maintaining device simplicity while enabling precise event cause identification.
2Loss of information
If yarn information is stored for every package and divided length, then the event cause identification is improved, but the memory usage increases
Solution Approach 1:
The patent applies local quality by storing detailed yarn information selectively for different time periods and packages rather than uniformly for all data. The system stores yarn information with specific time period identifiers and package IDs, allowing detailed analysis where needed while reducing storage for other segments. This selective storage approach optimizes memory usage while maintaining the ability to identify event causes in specific packages and time periods.
3Measurement precision
If the yarn length is divided into many segments, then the event location precision is improved, but the data processing complexity increases
Solution Approach 1:
The patent implements periodic action by dividing the yarn winding process into discrete time periods and storing yarn information for each period separately. The system uses periodic time period identifiers (first time period, second time period, etc.) to organize data, which simplifies the management of divided yarn segments compared to continuous segmentation. This periodic structure enables precise event location identification while keeping the data management system relatively simple through regular, structured data organization.

AI summary
A yarn information acquiring device (4) includes a yarn information acquiring section (41) that, when yarn is wound to form a package in a yarn winding machine (1), acquires yarn information indicating a state of the yarn. The yarn information acquiring section (41) manages the yarn information by the package, and acquires the yarn information for each of divided yarn lengths that are a plurality of lengths into which a fully wound yarn length in the package fully wound is divided.
