Contact Roller Static Electricity Remover Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In yarn winding apparatuses, static electricity accumulates in contact rollers, leading to potential discharge issues that can damage equipment and affect yarn quality, especially when static electricity removers are placed near the surface and exposed to contaminants like cotton flies and oil mist, causing reduced effectiveness and safety concerns.
Innovation Solution
Integrating a static electricity remover inside the rotating body of the contact roller, away from its surface, to prevent contamination and ensure continuous effective static electricity removal without exposing the contact roller to damage from discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static electricity remover is arranged in the vicinity of the surface of the contact roller, then static electricity can be discharged from the contact roller, but the static electricity remover is exposed to contaminants (cotton flies, oil mist) which reduces its effectiveness
Solution Approach 1:
The static electricity remover is nested inside the contact roller, positioned within the hollow interior space. This nesting arrangement allows the static electricity remover to remain close to the outer circumferential surface for effective static electricity discharge while being protected from external contaminants by the contact roller's wall structure.
2Reliability
If a static electricity remover is arranged near the contact roller surface, then static electricity can be removed, but electric discharge may damage the contact roller surface and affect yarn quality
Solution Approach 1:
The contact roller's wall structure serves as an intermediary between the static electricity remover and the external environment. The static electricity remover is positioned inside the contact roller, using the roller's wall as a protective barrier that prevents direct contact between the discharge mechanism and the outer surface, thus preventing surface damage while maintaining discharge functionality.
3Reliability
If a static electricity remover is placed near the contact roller, then static electricity can be discharged, but the discharge process is visible which causes operator anxiety
Solution Approach 1:
The static electricity remover is nested within the hollow interior of the contact roller, which conceals the electric discharge process from external view. The contact roller's wall structure acts as a shield, allowing the discharge to occur internally while preventing visual observation from the outside, thereby eliminating operator anxiety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This arrangement maintains the static electricity removal capability over time, protects the contact roller from damage, and reduces operator anxiety by hiding the discharge process, ensuring consistent yarn quality and safety.

AI summary
A problem, which occurs when a static electricity remover is disposed in the vicinity of the surface of a rotating body, is solved in a yarn winding apparatus including the rotating body which rotates while being in contact with the outer circumferential surface of a package. A yarn winding apparatus forming a package by winding a yarn onto a bobbin includes a rotating body 18 configured to rotate while being in contact with the outer circumferential surface of the package. In the yarn winding apparatus, a static electricity remover 31 for removing static electricity from the rotating body 18 is provided inside the rotating body 18 so as not to make contact with the rotating body 18.
