Ring Spinning Head Winding Optimization via Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ring spinning cops produced on spinning machines often have uneven winding conditions, leading to increased thread tension and breakage during rewinding, which affects the quality of the final package and efficiency of the winding process.
Innovation Solution
A method where data on thread errors from the winding machine is transmitted back to the ring spinning machine to adjust the spinning program, specifically adjusting the movement and speed of the ring bench in problematic areas to improve winding conditions, and monitoring spinning tension to prevent excessive thread breaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ring spinning heads are wound according to a predetermined spinning program, then the production efficiency is maintained, but the winding uniformity deteriorates leading to thread tension increase and breakage
Solution Approach 1:
The patent implements a feedback mechanism where thread defect data from the winding machine is transmitted back to the ring spinning machine's control unit. The system continuously monitors thread defects during winding and uses this information to automatically adjust spinning parameters (such as ring bench movement speed and position) in real-time, creating a closed-loop control system that maintains both productivity and winding quality.
Solution Approach 2:
The patent transitions from a static predetermined spinning program to a dynamic adaptive spinning process. The control unit continuously modifies spinning parameters based on real-time thread defect monitoring, making the spinning program adaptable to actual winding conditions. This dynamic adjustment optimizes winding uniformity without compromising production efficiency.
2Manufacturing precision
If the thread tension is monitored and defects are cleaned out, then the quality of cross-wound bobbins is improved, but the thread breakage risk increases due to tension fluctuations
Solution Approach 1:
The patent applies preliminary action by adjusting the ring spinning head winding parameters before the thread is rewound. The system proactively optimizes the winding structure of ring spinning heads to prevent excessive tension during subsequent unwinding. By pre-adjusting the winding uniformity based on defect data, the system reduces tension fluctuations and breakage risk before the threading process begins.
Solution Approach 2:
The patent implements preliminary anti-action by using thread defect monitoring data to preemptively adjust spinning parameters that would otherwise cause problematic winding areas. The control unit modifies the spinning program in advance to counteract potential tension issues, preventing thread breakage before it occurs during the winding process.

AI summary
The invention relates to a method or device for influencing the winding condition of ring spinning heads (9) produced at workstations (50) of ring spinning machines (30) according to a predetermined spinning program, which are then rewound into cross-wound bobbins (15) at workstations (2) of a winding machine (1) downstream in the production process, wherein the threads (31) unwinding from the ring spinning heads (9) are continuously monitored, thread defects are recorded, and thread defects exceeding predetermined limits are removed. According to the invention, data obtained by the workstations (2) of the winding machines (1) during the rewinding processes of the ring spinning heads (9), and relating to the thread defects of the ring spinning heads (9), are transmitted back to the control unit (57) of the associated ring spinning machine (30) and used there to optimize the winding condition of new ring spinning heads (9).
