Take-up Winding Facility Yarn Feeding Roller Vertical Redesign
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional take-up winding facilities face challenges in maintaining yarn quality and facility size as throughput increases, leading to variations in yarn tension and friction, which affect yarn quality and require increased facility height and complexity.
Innovation Solution
The take-up winding facility is designed with strategically positioned yarn feeding rollers that maintain the angle between the yarn path and the vertical direction, optimizing yarn tension and eliminating the need for additional rollers, thereby reducing facility height and complexity while ensuring stable yarn winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of bobbins installed on a bobbin holder shaft is increased to increase throughput, then the productivity increases, but the length of the bobbin holder shaft increases, causing the angle between the yarn path and the vertical direction to exceed the predetermined value, which deteriorates the yarn quality
Solution Approach 1:
The patent introduces a yarn feeding roller positioned above the take-up winding machine, changing the spatial arrangement from a horizontal extension to a vertical configuration. This dimensional change allows multiple bobbins to be installed without increasing the horizontal angle of the yarn path, maintaining yarn quality while enabling increased throughput.
Solution Approach 2:
The yarn feeding roller acts as an intermediary component that redirects the yarn path from a horizontal trajectory to a vertical one. This intermediary device enables the separation of the yarn feeding function from the take-up winding machine, allowing independent optimization of the bobbin holder shaft length and yarn path angle.
2Manufacturing precision
If the distance from the take-up winding machine to the yarn feeding roller is increased to maintain the yarn path angle, then the yarn quality is preserved, but the height of the take-up winding device increases, resulting in a larger facility that increases building costs and air conditioning costs
Solution Approach 1:
The invention repositions the yarn feeding roller in the vertical dimension above the take-up winding machine rather than extending horizontally. This allows the yarn path angle to be maintained at a predetermined value or less while minimizing the overall facility height, as the yarn path now extends vertically rather than horizontally.
3Manufacturing precision
If two yarn feeding rollers are located immediately before each take-up winding machine to divisionally guide yarns, then the yarn path angle can be maintained, but the take-up winding device becomes complicated
Solution Approach 1:
The patent extracts the yarn feeding function from the take-up winding machine by positioning the yarn feeding roller above it. This separation allows the take-up winding machine to focus on its primary function while the yarn feeding roller handles yarn guidance, simplifying the overall device structure compared to adding multiple rollers immediately before each take-up winding machine.
4Productivity
If the number of yarns spun out by a spinning machine is increased to increase throughput, then the productivity increases, but the length of the bobbin holder shaft increases, causing variations in tension or friction applied to each yarn, which deteriorates the yarn quality
Solution Approach 1:
By repositioning the yarn feeding roller vertically above the take-up winding machine, the patent enables increased throughput through additional bobbins without increasing the horizontal bobbin holder shaft length. This maintains consistent tension and friction conditions for all yarns, preserving yarn quality while achieving higher productivity.
