Segmented Yarn Shifter Units for Winding Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding devices face inefficiencies due to the increased weight and inertia of components when handling multiple bobbins, leading to sluggish movement and yarn waste, and are not easily adaptable to changes in the number of bobbins or yarns being wound.
Innovation Solution
A yarn winding device with shifter units that are divisible into individual units, allowing for quick detachment and shifting of yarns, and are designed to be easily increased or decreased in number, with each shifter unit being minimized in size to improve movement efficiency and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of bobbins attached to a single bobbin holder is increased, then the productivity is improved, but the weight of the yarn flip-up guide and slidable component increases, causing sluggish movement and yarn waste
Solution Approach 1:
The patent divides the single long yarn flip-up guide and slidable component into multiple separate small guides, each corresponding to one bobbin. This segmentation reduces the weight and inertia of each individual guide, enabling quick and stable yarn detaching and shifting while accommodating multiple bobbins simultaneously.
2Productivity
If the number of bobbins is increased, then the productivity is improved, but the length of the yarn flip-up guide and slidable component increases, causing sluggish movement
Solution Approach 1:
The patent segments the single long guide structure into multiple short guides distributed along the bobbin holder. Each short guide has minimal length required for its specific bobbin, reducing the overall movement mass and improving response speed while maintaining the capability to handle multiple bobbins.
3Adaptability or versatility
If the number of bobbins is changed due to model change, then the adaptability is improved, but the existing yarn flip-up guide and slidable component are unlikely to be reusable, requiring new design
Solution Approach 1:
The patent creates multiple independent small guides that can be easily added or removed based on the required number of bobbins. This modular approach allows quick reconfiguration for different production models without redesigning the entire guide system, significantly improving adaptability and component reusability.
Solution Approach 2:
The patent makes the guide system dynamically configurable by allowing the number of small guides to be adjusted according to production requirements. This dynamic adaptability enables the system to efficiently handle different numbers of bobbins and yarn types without requiring complete redesign.
4Productivity
If the yarn flip-up guide and slidable component are made long to accommodate more bobbins, then the productivity is improved, but the movement speed decreases due to increased inertia
Solution Approach 1:
The patent segments the guide system into multiple small independent units, each with minimal mass. This allows simultaneous processing of multiple yarns while maintaining fast movement speed for each individual guide, resolving the contradiction between throughput and speed.

AI summary
An objective is to provide a yarn winding device having shifter units (8) dividable into individual units, thereby making it possible to quickly detach and shift yarns and flexibly accommodate changes in the number of bobbins. The yarn winding device includes a plurality of shifter units (8) that detaches yarns Y from traverse units (6) and shift the yarns Y to the outside of the traversal ranges of the corresponding traverse units (6), when the yarns Y are transferred from fully-wound packages (10) to empty bobbins. The shifter units (8) are arranged to be dividable into individual units.
