Wire Winding System Maintaining Twist Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The loss of twist in the free end of a wire during spool change results in damaged sections at the center of the spool, making it difficult to access and unwind the wire efficiently.
Innovation Solution
A system for winding the wire from the central axis of a coil, utilizing a support mechanism, displacement mechanism, gripping interface, and cutting mechanism to maintain twist integrity, ensuring the free end is cut and wound without alteration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wire is cut during spool change operation, then the winding operation can transfer from one coil to another, but the twist along the free end of the wire is lost
Solution Approach 1:
The patent applies preliminary action by gripping the wire at a specific position downstream of the free end before cutting occurs. The displacement mechanism positions and secures the wire at the gripping interface upstream of the cutting zone, ensuring that the portion of wire to be wound is already prepared and protected from twist loss before the actual cutting and spool change operation takes place.
2Productivity
If the free end of the wire is cut and wound onto the second spool, then the winding operation continues, but a damaged section is created at the center of the spool
Solution Approach 1:
The patent extracts the problematic free end portion of the wire from the winding process. By gripping the wire downstream of the free end and positioning it at the gripping interface upstream of the cutting zone, the system effectively removes the damaged or altered twist portion from being wound onto the spool, preventing the creation of damaged sections at the spool center that would be difficult to access.
3Ease of manufacture
If the wire is gripped at the free end for winding, then the winding operation can start, but the twist along the free end is altered
Solution Approach 1:
The patent introduces an intermediary gripping interface that acts as a mediator between the free end of the wire and the winding operation. Instead of gripping the free end directly, the displacement mechanism positions the wire at this intermediate gripping interface upstream of the cutting zone, allowing the winding operation to initiate with a secure grip while maintaining twist uniformity in the portion of wire that is actually wound.

AI summary
The present invention relates to a winding system for a wire end (1) of a central axis (2) of a reel, characterized in that the system comprises: - a support means (3) for the central axis (2), the support means (3) being associated with a mechanism for driving axial rotation of this axis (2), - a displacement mechanism (5) for a portion of the wire (1) to be wound positioned downstream of the free end (11) of the wire (1), - a gripping interface (6) for catching a portion of the wire (1) to be wound, this interface (6) being positioned at the end of the central axis (2) of the reel and fixed in rotation with the central axis (2) to drive the winding of the wire (1) around the central axis (2), - a cutting mechanism (4) for the wire (1) upstream of the portion of the wire (1) interacting with the gripping interface (6).
