Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thread twisting and spinning machines face challenges in increasing the number of balloon regions without incurring high costs and complex modifications, which are necessary to reduce thread tension and improve productivity.
Innovation Solution
A method and accessory that increase the height of the balloon region by adding a guiding accessory, such as a clip or thread lifting mechanism with rollers and conveyor belt, to separate the guiding means from the twisting means, allowing for multiple balloon regions without altering the entire machine structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the height of the balloon region is increased to create multiple balloon regions, then thread tension is reduced and productivity is improved, but the machine structure becomes more complex and costly
Solution Approach 1:
The balloon region is segmented into multiple consecutive balloon regions (typically 2-20 regions) along the vertical height. This segmentation allows the thread to form multiple loops between the feeding means and twisting means, effectively reducing the tension in each individual balloon region while maintaining high productivity. The segmentation is achieved by controlling the rotation speed of the twisting means to create oscillating spiral diameters in the thread track.
Solution Approach 2:
The invention utilizes the vertical dimension by increasing the height of the balloon region area. Instead of expanding horizontally, the thread path is extended vertically to accommodate multiple balloon regions. This dimensional change allows for reduced thread tension and improved productivity without significantly increasing the horizontal footprint of the machine.
2Force
If the separation distance between guiding means and twisting means is increased to accommodate multiple balloon regions, then thread tension is reduced, but the machine footprint and complexity increase
Solution Approach 1:
The separation between guiding means and twisting means is achieved primarily in the vertical dimension rather than horizontally. By stacking multiple balloon regions vertically, the effective separation distance is increased without proportionally increasing the horizontal machine footprint. This allows for reduced thread tension while maintaining a compact machine layout.
Solution Approach 2:
Multiple balloon regions are nested vertically within the available space between the guiding means and twisting means. The consecutive balloon regions are arranged one above another, efficiently utilizing the vertical space and reducing the horizontal area required for the same tension-reduction effect.
3Productivity
If the rotation speed of twisting means is increased to improve productivity, then thread tension increases and thread quality deteriorates, but lowering rotation speed reduces productivity
Solution Approach 1:
The rotation speed benefit is distributed across multiple balloon regions. While the twisting means rotates at high speed for productivity, the tension is distributed across 2-20 consecutive balloon regions rather than concentrated in a single region. This segmentation allows high rotation speeds without proportionally increasing thread tension, thereby maintaining thread quality.
Solution Approach 2:
The invention changes the operational parameters by creating oscillating spiral diameters in the thread track through controlled rotation speeds. The twisting means rotates at a speed that produces a helical track with varying diameters, creating multiple balloon regions. This parameter change allows the system to operate at higher speeds while distributing the tension across multiple regions, maintaining both productivity and thread quality.
