Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multiple winding apparatuses face difficulties in adjusting the length of connecting wires between coils, resulting in wires being longer than the outer diameter of the coils, making it impossible to obtain coils connected by wires shorter than the outer diameter.
Innovation Solution
A multiple winding apparatus and method that includes a winding core, spindle shaft, wire rod feeding flyer, winding core removal mechanism, and a supporting member to adjust the length of connecting wires by supporting winding cores at desired intervals, allowing for the formation of coils connected by wires shorter than the outer diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a larger number of spindle shafts are parallelly arranged to increase coil production capacity, then productivity is improved, but the interval between spindle shafts increases causing connecting wire length to become longer than coil outer diameter
Solution Approach 1:
The invention transitions from a single-plane parallel arrangement of spindle shafts to a multi-dimensional configuration where spindle shafts are arranged both parallel to each other and at different positions along the wire rod feeding direction. This spatial reorganization allows increased productivity through more spindles while maintaining short connecting wire lengths by strategically positioning spindles at intervals in the feeding direction.
Solution Approach 2:
The invention introduces dynamic positioning capabilities where the interval between spindle shafts in the wire rod feeding direction can be adjusted. This allows the system to adaptively optimize the balance between productivity (number of spindles) and connecting wire length based on specific production requirements, rather than being fixed by a static parallel arrangement.
2Length of moving object
If the interval between spindle shafts is reduced to shorten connecting wires, then connecting wire length is improved, but coil interference with adjacent coils occurs
Solution Approach 1:
By arranging spindle shafts at different positions in the wire rod feeding direction rather than solely in parallel, the invention creates additional spatial separation between adjacent coils. This multi-dimensional spacing prevents coil interference while allowing the interval in the parallel direction to be reduced, thereby achieving short connecting wire lengths without harmful coil interactions.
3Device complexity
If spindle shafts are arranged in parallel to simplify the apparatus structure, then device complexity is reduced, but the length of connecting wires is determined by the interval and cannot be adjusted
Solution Approach 1:
The invention implements adjustable intervals between spindle shafts in the wire rod feeding direction, providing dynamic adaptability for connecting wire length. This allows the system to be configured for different production requirements without fundamentally changing the parallel spindle structure, thus maintaining relative structural simplicity while gaining flexibility in connecting wire length adjustment.

AI summary
The multiple winding apparatus for coil includes a winding core, a spindle shaft on a tip end of which the winding core is removably mounted and which rotates together with the winding core, a wire rod feeding flyer which feeds a wire rod while rotating around the winding core mounted on the spindle shaft, a winding core removal mechanism which removes the winding core from the spindle shaft by moving the winding core in an axial direction, a supporting member which faces the spindle shaft and supports a plurality of the winding cores removed by the winding core removal mechanism at desired intervals in the axial direction, and a support member moving mechanism which moves the supporting member supporting the winding cores from a position facing the spindle shaft in a direction away from the spindle shaft.
