Yarn Production System Static Electricity Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity generated during yarn threading in synthetic resin yarn production systems due to contact with metal members causes yarn repulsion and splitting, leading to threading issues, and existing solutions like ceramic materials are costly and prone to damage.
Innovation Solution
Incorporating insulators between metal members and the ground plane to prevent static electricity from escaping, using insulative materials for holder members and cap members to saturate static electricity in metal components, reducing yarn static charge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal members are used in yarn threading, then cost and strength are improved, but static electricity is generated causing yarn repulsion and splitting
Solution Approach 1:
An insulator is introduced as an intermediary component between the metal member and the ground plane. This insulator prevents the metal member from being grounded, thereby suppressing static electricity generation while maintaining the structural strength of the metal member. The insulator acts as a mediator that blocks the charge transfer path without compromising the mechanical integrity of the system.
Solution Approach 2:
The electrical conductivity parameter of the system is changed by introducing an insulating material. By controlling the electrical properties (making the support structure electrically insulating rather than conductive), the static electricity generation is suppressed while the metal member retains its mechanical strength and functional properties.
2Object-affected harmful factors
If ceramic materials are used to suppress static electricity, then static electricity generation is reduced, but cost increases and the material becomes fragile
Solution Approach 1:
Instead of using expensive and fragile ceramic materials, the invention employs a metal member combined with an insulator. This approach uses more durable, cost-effective materials that can withstand repeated use and cleaning cycles in industrial environments, while achieving the same static electricity suppression effect.
Solution Approach 2:
The invention creates a composite structure combining metal (for strength and durability) with insulating material (for static electricity suppression). This composite approach leverages the advantages of both materials: the metal provides mechanical strength and resistance to damage, while the insulator provides electrical isolation to prevent static electricity generation.
3Reliability
If metal members are grounded, then electrical safety is improved, but static electricity in yarns increases due to continuous charge transfer
Solution Approach 1:
The grounding connection is extracted or removed from the system. By taking out the ground plane connection that would otherwise provide a continuous charge transfer path, the system prevents the accumulation and transfer of static charge to the yarns, thereby reducing yarn static charge while maintaining electrical safety through alternative means.

AI summary
Static electricity generated due to contact of yarns with a metal member is suppressed during yarn threading in a yarn production system. A yarn production system in which yarns Y made of synthetic resin and spun out from a spinning apparatus are wound by a winding device includes: a metal member 32 which is used in yarn threading of threading the yarns Y spun out from the spinning apparatus to the winding device and members along a yarn path and makes contact with the yarns Y; and an insulator 33 which prevents static electricity generated in the metal member 32 due to contact with the yarns Y from escaping from the metal member 32 to a ground plane.
