Cabling Spindle Hood Convex Transition Balloon Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cabling spindles have high energy consumption due to the formation of a yarn balloon during the cabling process.
Innovation Solution
A conical cabling hood with a convex upper region is designed, allowing the balloon yarn-guide eye to be positioned closer to the hood, reducing the size of the yarn balloon and thus lowering energy consumption, and is compatible with both open yarn balloons and balloon limiters, enabling retrofitting of existing machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a conventional conical cabling hood is used, then the structure is simple and easy to manufacture, but the yarn balloon size is large leading to high energy consumption
Solution Approach 1:
The cabling hood is designed with a convex upper region that transitions from the conical shape into a rounded, convex form. This curvature allows the balloon yarn-guide eye to be positioned closer to the hood, minimizing the yarn balloon size and reducing the energy required to rotate the balloon during the cabling process
2Use of energy by moving object
If the balloon yarn-guide eye is positioned closer to the cabling hood, then the yarn balloon size is reduced and energy consumption decreases, but the creel yarn may contact the cabling hood causing operational issues
Solution Approach 1:
The convex upper region creates a rounded surface profile that prevents the creel yarn from making contact with the cabling hood even when the balloon yarn-guide eye is positioned close to the hood. This curvature ensures reliable yarn guidance while maintaining minimal balloon size for reduced energy consumption
