Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional take-up winding facilities face challenges in miniaturization and operational complexity due to increased device height and yarn quality variations when handling multiple bobbins, leading to higher costs and reduced operability.
Innovation Solution
The take-up winding facility employs multiple yarn feeding rollers that share the operation of spreading yarns, allowing each roller to take off and feed yarns to the take-up machine, optimizing tension, and simplifying the layout by integrating functions and reducing the need for additional rollers, thus minimizing device height and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of bobbins installed in one take-up winding machine is increased, then the productivity is improved, but the device height increases and the facility size becomes larger
Solution Approach 1:
The patent reconfigures the spatial arrangement by positioning yarn feeding rollers above the take-up winding machine rather than in front, utilizing vertical space more efficiently. This dimensional change allows multiple bobbins to be accommodated without proportionally increasing device height, as the yarn feeding path is optimized through vertical placement of feeding rollers at specific heights to control spread angles.
2Productivity
If the number of bobbins installed in one take-up winding machine is increased, then the productivity is improved, but the yarn quality varies among bobbins due to larger spread angle
Solution Approach 1:
The patent applies local quality by positioning each yarn feeding roller at a specifically controlled height above the take-up winding machine. This localized height control ensures that each roller maintains an appropriate spread angle for its specific yarn feeding position, allowing multiple bobbins to be served while maintaining uniform yarn quality across all positions despite the increased number of bobbins.
3Manufacturing precision
If multiple yarn feeding rollers are provided for each take-up winding machine, then the yarn quality uniformity is improved, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing each yarn feeding roller to perform multiple functions: feeding yarn to multiple bobbins, controlling spread angle through height adjustment, and maintaining yarn quality uniformity. This multi-functional design reduces the need for separate specialized components for each function, thereby reducing overall device complexity while achieving yarn quality uniformity across multiple bobbins.
