Padding Separation Channel With Oscillating Combs and Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating padding from textile article linings, such as down jackets, are inefficient, labor-intensive, and result in contaminated padding due to mixing with lining fragments, violating recycling regulations and requiring manual operation.
Innovation Solution
A machine with oscillating combs and suction means in an operating channel automatically separates padding from lining by making fragments jump and separate, using shaking means to mechanically disengage padding from lining fragments and suction to collect clean padding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic shredding is used to separate padding from lining, then productivity is improved, but the padding becomes contaminated with lining fragments
Solution Approach 1:
The patent divides the separation process into distinct stages: initial shredding to open the garment structure, followed by a refining stage where rotating combs with progressively finer teeth selectively remove padding from lining fragments. This multi-stage segmentation allows both high productivity and high cleanliness.
Solution Approach 2:
The patent applies different separation mechanisms to different stages of the process. The initial shredding uses coarse mechanical action, while the final separation uses fine comb teeth that locally and selectively engage with padding versus lining fragments based on their different physical characteristics.
2Manufacturing precision
If manual separation is used to achieve high padding quality, then manufacturing precision is improved, but productivity decreases and labor costs increase
Solution Approach 1:
The patent employs rotating combs that automatically separate padding from lining fragments through their own rotational motion and the natural interaction of materials with the comb teeth. The process requires minimal operator intervention beyond loading and monitoring, achieving both high quality and productivity.
Solution Approach 2:
The patent replaces manual mechanical separation with an automated mechanical system using rotating combs driven by motors. This substitution maintains the gentle, selective separation action needed for high quality while dramatically increasing productivity through automation.
3Productivity
If automatic shredding is used, then productivity is improved, but device complexity increases due to additional separation equipment
Solution Approach 1:
The patent combines the shredding function and the separation function into a single integrated machine. The rotating combs serve dual purposes: they further break down material while simultaneously separating padding from lining, reducing the need for entirely separate equipment.
Solution Approach 2:
The rotating comb mechanism performs multiple functions: it continues the shredding process, separates padding from lining fragments, and sorts materials into different collection containers. This multi-functionality reduces overall system complexity despite the automated nature of the process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
suction means (12) placed in communication with said second outlet section (6) and configured to suck said padding mass from said operating channel (3) towards said second outlet section (6)
Implementation Method 2
shaking means (7) operationally housed in said operating channel (3) and configured to intercept said plurality of fragments of padded textile articles and to make them jump until said mass of padding is separated from said plurality of lining fragments

AI summary
A machine for separating a padding from a lining of padded textile articles includes a support structure internally defining at least one operating channel that extends between: an inlet section in which a plurality of fragments of padded textile articles are introduced into the operating channel; a first outlet section in which a plurality of lining fragments are expelled from the operating channel; and a second outlet section in which a mass of padding separated from the lining fragments is expelled from the operating channel. The machine also includes shaking means operationally housed in the operating channel that intercepts the plurality of fragments of padded textile articles, urging them inside the operating channel to thus mechanically separate the mass of padding from the plurality of lining fragments.
