Yarn Spindle Coding During Winding for Accurate Spindle Matching
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 and attaching information codes to yarn spindles during the winding process itself, before the spindles are transported and their order may change. The winding machine generates identification information (including spindle position, winding time, and other parameters) and attaches it to each spindle while it is still in the winding machine, ensuring accurate coding is completed before any potential reordering occurs.
2Manufacturing precision
If coding is performed during the winding process, then coding accuracy is maintained, but the winding machine must perform additional coding functions
Solution Approach 1:
The patent applies universality by enabling the winding machine to perform multiple functions: it not only winds the yarn into spindles but also generates identification information, attaches information codes to the spindles, and manages coding operations. The winding machine integrates coding capabilities into its existing structure, allowing it to serve both winding and coding functions without requiring a completely separate coding system.
3Productivity
If coding is delayed until after winding, then the winding machine can focus solely on winding, but coding efficiency and production throughput are reduced
Solution Approach 1:
The patent applies merging by combining the coding operation with the winding operation. Instead of performing coding as a separate step after winding, the information code generation and attachment processes are merged into the winding sequence itself. This allows the winding machine to complete both winding and coding tasks in a single continuous operation, eliminating idle time and improving overall production throughput.

AI summary
Provided is a yarn spindle coding method including: when determining that yarn spindles are fully wound, sleeving the yarn spindles in the winding machine sequentially outside a yarn connecting rod of a doffer, and updating the number of unloading times of the winding machine and recording first doffing time of each yarn spindle; generating a first information code of each yarn spindle based on identification information of the winding machine, the updated number of unloading times, the first doffing time and position information of each yarn spindle; and sending each first information code to the doffer, so that the doffer determines a corresponding target yarn spindle among the yarn spindles according to a matching degree between the first doffing time and second doffing time of each yarn spindle recorded by the doffer and code the information code on a corresponding target yarn spindle.
