Movable Yarn Bring-Down Apparatus for Multi-Spool Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing yarn bring-down apparatuses require dedicated devices for each spun yarn take-up apparatus, leading to increased costs and maintenance expenses when multiple spinning apparatuses are lined up in a system.
Innovation Solution
A movable yarn bring-down apparatus with a wagon main body and a yarn bring-down member that can be positioned at suitable locations, using hooking portions, a wire system, and a guide member to bring down yarns from the upper floor to the lower floor, eliminating the need for dedicated apparatuses at each take-up unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated yarn bring-down apparatus is provided for each spun yarn take-up apparatus, then yarn bring-down can be performed at each take-up apparatus, but the system cost and maintenance cost increase
Solution Approach 1:
The yarn bring-down apparatus is designed as a universal device that can serve multiple spun yarn take-up apparatuses. The wagon main body can move to different locations and the yarn bring-down member can be extended to different positions, allowing a single apparatus to perform yarn bring-down for multiple take-up points, thereby reducing the total number of devices needed in the system
Solution Approach 2:
The apparatus incorporates movable components including the wagon main body that can move along the upper floor and the yarn bring-down member that can extend and retract. This dynamic design allows the fixed-number apparatus to adapt to multiple take-up apparatuses, providing the flexibility of having dedicated devices for each location without actually multiplying the device count
2Productivity
If multiple spinning apparatuses and spun yarn take-up apparatuses are lined up to improve production efficiency, then yarn production capacity increases, but the number of required yarn bring-down apparatuses increases
Solution Approach 1:
The yarn bring-down apparatus is designed as a universal device that can serve multiple spun yarn take-up apparatuses. The wagon main body can move to different locations and the yarn bring-down member can be extended to different positions, allowing a single apparatus to perform yarn bring-down for multiple take-up points, thereby reducing the total number of devices needed in the system
Solution Approach 2:
The function of yarn bring-down is merged into a single movable apparatus that can serve multiple take-up apparatuses. By combining the bring-down capability with mobility and extendability, the system reduces the number of separate bring-down devices required, thereby lowering overall system complexity while supporting expanded production capacity

AI summary
Yarn bring-down at each spun yarn take-up apparatus us achieved with low cost, even when a large number of spun yarn take-up apparatuses are lined up. A yarn bring-down apparatus 5 is provided in a spun yarn take-up system configured to take up, on a lower floor, yarns spun out from a spinning apparatus on an upper floor, and includes a wagon main body 30 configured to be movable on the upper floor and a yarn bring-down member 31 which is provided in the wagon main body 30 and is capable of moving down to the lower floor while retaining the yarns Y spun out from the spinning apparatus.
