Curved Yarn Production System Reducing Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Increasing the number of spinning packs in a yarn production system while maintaining yarn quality is challenging due to increased yarn angles and system height, as the distance between guides needs to be adjusted, leading to a larger system height.
Innovation Solution
Arranging spinning packs in a curved or intersecting straight lines configuration to reduce horizontal distances between guides, allowing for a decrease in vertical distances and thus reducing the overall system height, while ensuring yarn angles remain within a manageable range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of spinning packs is increased to increase yarn production capacity, then productivity is improved, but the distance between first guides and second guide increases horizontally causing yarn angle to increase which deteriorates yarn quality
Solution Approach 1:
The patent applies dimensional change by transitioning from a conventional linear arrangement of spinning packs to a curved arrangement following an arc. This spatial reconfiguration allows the first guides to be positioned closer to the second guide vertically while maintaining adequate horizontal spacing, thereby reducing the yarn angle to 9 degrees or less even when the number of spinning packs is increased. The curved arrangement effectively utilizes three-dimensional space to resolve the conflict between productivity and yarn quality.
2Manufacturing precision
If the distance between first guides and second guide is increased vertically to reduce yarn angle, then yarn quality is improved, but the height of the entire yarn production system increases
Solution Approach 1:
The patent resolves this contradiction by changing the spatial arrangement from a vertical stacking approach to a curved horizontal arrangement. By positioning spinning packs along an arc, the system achieves the required yarn angle reduction through horizontal distribution rather than vertical separation, thereby maintaining compact system height while ensuring yarn quality.
3Length of stationary object
If spinning packs are arranged in a curved line configuration, then system height is reduced and yarn quality is maintained, but device complexity increases
Solution Approach 1:
The patent employs curvature by arranging spinning packs along an arc rather than in a straight line. This curved configuration naturally reduces the horizontal distance between guides while maintaining adequate spacing between spinning packs, thereby reducing system height and yarn angle. The arc-shaped arrangement is a geometric solution that achieves compact dimensions without significantly complicating the overall device structure.

AI summary
An object of the present invention is to reduce height of a yarn production system including a spinning apparatus having spinning packs, even in a case in which the number of the spinning packs is increased. A yarn production system 1 of the present invention includes spinning packs 22 in each of which molten polymer is stored and each of which spins out a yarn Y downward from a spinneret 24 provided at a lower end portion of each of the spinning packs 22, a spinning beam 21 in which the spinning packs 22 are inserted, first guides 6 which are provided immediately below the spinning packs 22 and which individually guide yarns Y, and a second guide 7 which is provided below the first guides 6 and which causes the yarns Y guided by the first guides 6 to be converged. The spinning packs 22 are arranged along a first arc 51 and a second arc 52 which is inside the first arc 51, in plan view.
