Spun Yarn Take-Up Machine Ground Wire for Static Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of yarns processed by a spun yarn take-up machine and higher winding speeds lead to significant static electricity generation due to friction between yarns and the threading assisting tool, resulting in potential electric shocks for operators during yarn threading.
Innovation Solution
A conductive frame with a ground wire attached to both the frame and the yarn threading assisting tool allows for the discharge of static electricity, preventing electric shocks by ensuring the ground wire is positioned above the yarn threading portions to avoid interference and improve workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of yarns processed and winding speed are increased, then productivity is improved, but the amount of static electricity generated increases causing electric shocks to operators
Solution Approach 1:
A ground wire is introduced as an intermediary element between the yarn threading assisting tool and the frame to provide a safe discharge path for static electricity. The ground wire acts as a mediator that transfers electric charge from the assisting tool through the operator's body to the frame, preventing direct electric shock to the operator while maintaining high-speed yarn processing capability
Solution Approach 2:
The invention converts the harmful static electricity generated during high-speed yarn processing into a beneficial discharge mechanism. By providing a controlled discharge path through the ground wire, the static electricity that would otherwise cause dangerous electric shocks is instead safely redirected to the frame, allowing operators to work comfortably at high speeds without risk of electric shock
2Reliability
If a ground wire is added to discharge static electricity, then operator safety is improved, but device complexity increases
Solution Approach 1:
The ground wire system is designed to be self-activating and requires no additional control mechanisms. The wire automatically provides a discharge path when the operator holds the yarn threading assisting tool, eliminating the need for switches, buttons, or complex control circuits while ensuring continuous safety protection
Solution Approach 2:
The ground wire serves multiple functions simultaneously: it provides a discharge path for static electricity, maintains electrical connection between the assisting tool and frame, and ensures operator safety without interfering with the mechanical yarn threading operation. This multi-functionality reduces the need for separate safety devices
