Yarn Winding Device Draw-Out Mechanism Defect Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding devices face inefficiencies in production due to frequent yarn breakage and defects, leading to suspended operations and increased power consumption, as higher winding speeds result in traversing errors and difficulty in removing defects without stopping the package rotation.
Innovation Solution
A yarn winding device equipped with a draw-out mechanism that allows continuous yarn winding by detecting defects and splicing operations without stopping the package, using an upper and lower yarn catching mechanism to manage yarn accumulation and splicing, and a control system to optimize yarn accumulation and rotation speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the package rotation is stopped to remove yarn defects, then defect removal is possible, but production efficiency decreases and time is lost
Solution Approach 1:
The patent applies preliminary action by accumulating yarn in advance before winding. The yarn accumulation device stores a sufficient length of yarn ahead of time, so when a defect is detected, the package can continue rotating while the accumulated yarn is used. This eliminates the need to stop the package for defect removal, maintaining production efficiency while ensuring defect-free winding.
2Ease of manufacture
If the package rotation is stopped to perform splicing operations, then yarn splicing can be completed, but winding time is lost
Solution Approach 1:
The patent implements continuity of useful action by enabling splicing operations to occur without stopping the package rotation. The yarn accumulation device provides continuous yarn supply, and the splicing device performs repairs or joins yarn ends while the package continues to rotate, eliminating idle time and maintaining continuous productive action.
3Productivity
If higher winding speeds are used to improve productivity, then production efficiency increases, but traversing errors occur
Solution Approach 1:
The patent uses the yarn accumulation device as an intermediary buffer between the high-speed winding process and the package. By accumulating yarn at controlled speeds before the winding point, the system can maintain high overall production speeds while the actual winding operation proceeds at precise, controlled rates, preventing traversing errors.
4Reliability
If the package rotation is stopped frequently for defect removal and splicing, then yarn quality is maintained, but power consumption increases
Solution Approach 1:
The patent reduces energy loss by performing preliminary yarn accumulation at moderate speeds. This stored yarn reserve allows the package to rotate continuously at optimal speeds without frequent stops, avoiding the high energy costs associated with repeatedly starting and stopping the heavy package rotation for defect removal and splicing operations.

Implementation Method 1
The yarn end of the unwound upper yarn is sucked and caught by a tip of the suction arm
Implementation Method 2
the yarn end of the yarn (lower yarn) on the new yarn supplying bobbin side is blown up by an air flow

AI summary
The invention relates to a winding unit (10) that includes an accumulator (61) which enables that a yarn (20) can be accumulated before it is wound into a package (30), and can be drawn out to a yarn supplying bobbin (21) side under the control of a unit control section (50). When a clearer (15) detects a yarn defect, the unit control section (50) draws out a portion of the yarn containing the yarn defect from the accumulator (61) to the yarn supplying bobbin (21) side. The drawn-out yarn (20) is caught and guided to a splicer device (14) by an upper yarn guide pipe (26). Furthermore, a lower yarn caught by a lower yarn guide pipe (25) is guided to the splicer device (14) for a yarn splicing operation.
