Yarn Spindle Coding During Winding for Sequence Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy and efficiency of yarn spindle coding in chemical fiber production are compromised when coding is delayed until after the order of spindles changes post-winding, leading to reduced precision.
Innovation Solution
A method and apparatus that generate and transmit information codes during the winding process, allowing the doffer to accurately code spindles based on matching doffing times, enabling simultaneous coding and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If coding is performed after the winding machine finishes and the order of spindles changes, then the coding process can be simplified, but the accuracy of coding is greatly reduced
Solution Approach 1:
The patent applies preliminary action by generating information codes during the winding process itself, before the spindles are transported and their order may change. The winding machine generates and transmits information codes to the doffer in real-time, ensuring that coding is performed while the spindle sequence is still fixed and identifiable, thus maintaining coding accuracy without requiring post-winding processing
2Measurement precision
If coding is performed during the winding process, then coding accuracy is maintained, but the device complexity increases due to real-time code generation and transmission systems
Solution Approach 1:
The patent merges the coding function with the existing winding machine and doffer systems. The information code generation is integrated into the winding machine's control system, and the transmission is combined with the existing doffer communication infrastructure. This integration allows real-time coding without adding separate complex coding equipment, as the existing mechanical and control systems are utilized for both winding and coding functions
3Productivity
If coding is delayed until after winding, then the winding machine can focus solely on production, but the overall production and transportation efficiency is reduced due to waiting time
Solution Approach 1:
The patent implements continuity of useful action by performing coding operations concurrently with the winding and transportation processes. The information codes are generated during winding and transmitted to the doffer, allowing coding to continue without interruption while the spindles are being transported. This eliminates idle waiting time and ensures that both winding production and coding operations proceed simultaneously, maximizing overall efficiency
