Spun Yarn Take-Up Layout for Single-Operator Yarn Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spun yarn take-up apparatuses require two staff members to perform yarn setting operations, leading to increased time and burden due to the need for transferring yarns between different levels and areas, necessitating a reduction in apparatus height and manpower.
Innovation Solution
A spun yarn take-up apparatus with a horizontal arrangement of the spooling and drawing sections, guided by a guide roller and distribution rollers, allowing a single operator to perform the yarn setting operation and reducing the apparatus' floor level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spun yarn take-up apparatus is arranged with processing assemblies below the spinning machine and spooling unit below the processing assemblies, then the yarn setting operation can be performed, but the apparatus height increases and requires multiple staff members
Solution Approach 1:
The patent changes the spatial arrangement from a vertical multi-level configuration to a horizontal single-level configuration. The spooling unit and processing assemblies are arranged horizontally on the same floor, eliminating the need for vertical stacking and reducing apparatus height while maintaining operational functionality.
Solution Approach 2:
The patent merges the previously separated work areas (processing area and spooling area) into a single integrated workspace on the same floor. This consolidation allows one operator to manage both yarn processing and spooling operations without transferring yarns between different levels or areas.
2Ease of operation
If multiple staff members perform the yarn setting operation, then the yarn setting can be completed, but the time required increases due to transferring suctioning gun between staffs
Solution Approach 1:
The patent combines the processing assemblies and spooling unit into a single integrated system on the same floor, allowing one operator to perform all yarn setting operations continuously without transferring the suctioning gun between multiple staff members, thereby reducing yarn setting time.
Solution Approach 2:
The horizontal arrangement enables continuous yarn setting operations by eliminating interruptions caused by staff coordination and equipment transfer. The single operator can maintain continuous action throughout the yarn setting process from processing to spooling.
3Ease of operation
If the apparatus is arranged vertically with multiple levels, then the yarn path can be established, but the operator burden increases due to high-place operation
Solution Approach 1:
The patent transitions from vertical multi-level arrangement to horizontal single-level arrangement, eliminating high-place operations and complex working positions while maintaining the necessary yarn path and processing functionality.
4Ease of operation
If the spooling unit and drawing section are arranged vertically, then the yarn path is established, but the floor level increases
Solution Approach 1:
The patent rearranges the spooling unit and drawing section from a vertical arrangement to a horizontal arrangement on the same floor level, using the horizontal dimension to establish the yarn path instead of vertical stacking, thereby reducing the required floor level.

AI summary
In order to provide a spun yarn take-up apparatus lower in floor level than a conventional apparatus, the spun yarn take-up apparatus comprises a spun yarn take-up unit 6 for taking up and drawing a plurality of yarns 100 spun from a spinning machine, and a spooling unit 8 for winding the plurality of yarns 100 delivered from the spun yarn take-up unit 6 to form a wound package. The spun yarn take-up unit 6 includes: a first guide section 10 for guiding the plurality of yarns 100 downstream along a yarn traveling direction; and a drawing section 28 including a plurality of rollers having at least one roller for drawing the plurality of yarns 100 guided by the first guide section 10; and a second guide section 62, 70 for guiding the plurality of yarns 100 from the drawing section 28 to the spooling unit 8. The spooling unit 8 and the drawing section 28 are arranged horizontally. The second guide section has a second relaxing roller 62 and the distribution section 70. The plurality of yarns 100 from the drawing section 28 are delivered to the spooling unit 8 through the distribution section 70 and the second relaxing roller 62.
