Winding Scraps Collection via Segmented Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding systems face inefficiencies in collecting and managing scraps, particularly in distinguishing and handling fine dusts and longer thread fluffs, which require different suction pressures and lead to clogged filters, affecting continuous operation.
Innovation Solution
The implementation of individual filters with fine and coarse mesh septums at each winding station, connected to a common collector, utilizing a high depression aspirator for periodic discharge of scraps through an inertial filter that separates and processes materials efficiently, preventing clogging and maintaining continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single suction system is used for both fine dusts and long fluffs, then the system structure is simple, but the filter clogs due to inability to handle different particle sizes effectively
Solution Approach 1:
The suction system is divided into two separate suction units: a first suction unit with a first filter for fine dusts and a second suction unit with a second filter for long fluffs. This segmentation allows each filter to handle specific particle sizes, preventing clogging while maintaining system functionality.
2Productivity
If high depression suction is used continuously, then long fluffs are effectively removed, but fine dusts are not efficiently collected and the system cannot switch between different suction requirements
Solution Approach 1:
The system dynamically switches between high depression suction for fluffs and low depression suction for dusts using a control unit that activates the appropriate suction unit based on operational requirements. This dynamic adaptation allows efficient handling of different particle types without continuous high depression operation.
3Productivity
If individual filters are installed at each winding station, then scraping efficiency is improved, but the system complexity and number of components increase
Solution Approach 1:
While individual filters are installed at each winding station for efficient scrap collection, the system merges the discharge of multiple filters through a common duct to a central collection point. This combining approach maintains high scraping efficiency while reducing the number of discrete collection points and simplifying the overall structure.

AI summary
Device for collecting scraps produced by a winder both for dust removal and for lengths of thread, wherein the winding units (23) are served by single aspirators (22) that individually equip each winding unit, and are each equipped with a pair of filters (50,51) for separating the dust and the lengths of thread, arranged in parallel and operating alternately. All filters are connected through a common duct (70) to a common inertial filter (80) for collecting the winding scraps that periodically discharges and receives the material held by such filters, one at a time and separately for each material.
