Braiding Machine Reel Carrier Orientation via Pinion Gears
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In thread braiding machines, the movement of the reel causes significant tension variations in the thread, affecting its quality and strength, as one part of the thread is under tension while another part is not, during the braiding process.
Innovation Solution
A braiding machine design where the reel carrier moves along a figure-of-eight shaped guide, with pinion gears meshing to maintain the reel carrier's orientation, ensuring consistent thread tension by preventing variations in the movement of the reel carrier mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the reel carrier moves along a curved trajectory during braiding, then the braiding process can be completed, but significant tension variations occur in the thread affecting quality and strength
Solution Approach 1:
A tensioning device acts as an intermediary element between the reel carrier and the thread, actively compensating for tension variations caused by the curved figure-of-eight trajectory. This mediator maintains constant thread tension despite the complex motion path, preventing strength degradation.
Solution Approach 2:
The system dynamically adjusts tensioning parameters through the tensioning device to compensate for variations in thread tension caused by the curved trajectory. By changing the tensioning force parameter in real-time, the system maintains optimal thread tension throughout the braiding process.
2Area of stationary object
If the reel carrier follows a figure-of-eight trajectory, then braiding coverage is achieved, but one part of the thread is under tension while another part is not
Solution Approach 1:
The tensioning device serves as a mediator that equalizes tension distribution across the entire thread length. It compensates for the uneven tension distribution caused by the figure-of-eight trajectory, ensuring uniform tension throughout the braiding coverage area.
Solution Approach 2:
The tensioning device creates equipotential conditions for thread tension throughout the braiding process. By actively adjusting tension, it ensures that all parts of the thread experience equivalent tension levels despite the varying positions in the figure-of-eight trajectory.
3Shape
If the reel carrier mechanism moves along a curved path, then the braiding pattern is formed, but thread tension varies significantly throughout the process
Solution Approach 1:
The tensioning device acts as an intermediary force mechanism that decouples the braiding pattern formation from thread tension variations. It maintains constant thread tension force while allowing the reel carrier to follow the curved figure-of-eight path needed for pattern formation.
Solution Approach 2:
The tensioning device provides a counteracting force to compensate for the tension variations induced by the curved trajectory. It acts as a mechanical counterweight that balances the fluctuating tension forces, maintaining steady thread tension throughout the braiding cycle.
