Solution Overview

Problem

Existing devices for treating strand-like textile goods in circulating systems face challenges in controlled deposition and guidance due to volume changes as the goods become saturated with treatment liquid, leading to increased distance from the exit point and potential uncontrolled depositing, especially when handling different batch sizes and properties.

Innovation Solution

A device with an adjustable storage wall in the goods store that can be moved transversely and in the direction of transport, allowing for automatic adjustment of the depositing area distance and cross-section to accommodate varying rope volumes, enabling controlled deposition and handling of different batch sizes without complex conversions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the goods store has a fixed cross-section storage area, then the device structure is simple, but the device cannot accommodate varying rope volumes at different saturation stages

Engineering Contradiction:
Improveaccommodation of varying rope volumesVSAvoidadjustable storage wall mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage wall is made adjustable rather than fixed, allowing it to change position according to the rope volume. The wall can be moved between a first position for dry rope (larger volume) and a second position for saturated rope (smaller volume), enabling the goods store to adapt to varying rope volumes throughout the treatment process.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If the depositing area is far from the exit point, then more treatment liquid can be applied, but the rope volume increases and controlled depositing becomes impossible

Engineering Contradiction:
Improvetreatment liquid saturationVSAvoidcontrolled depositing
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The adjustable storage wall dynamically repositions based on rope saturation level. When the rope is dry and has large volume, the wall is in the first position allowing greater distance from exit for liquid application. When the rope becomes saturated and volume decreases, the wall moves to the second position, reducing the distance and maintaining controlled depositing conditions throughout the treatment cycle.

Inventive Principle:
Principle #15Dynamics

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

Ensures problem-free guidance and controlled deposition of the rope bundle, allowing for efficient treatment of various rope sizes and properties without costly conversions, optimizing the use of the treatment container volume and reducing tensile forces required for feeding the rope back into the transport device.

Implementation Method 1

a transport nozzle arrangement which is arranged in the treatment container and is acted upon by a liquid and/or gaseous transport medium stream

Methodology Applied
Scientific EffectFluid stream transport: Fluid Spray

Implementation Method 2

the goods are not yet completely wetted with treatment liquid after the single contact with the treatment liquid (liquor) in the transport nozzle. After two to three revolutions of the closed strand of fabric, its volume decreases significantly because it is now completely saturated with treatment liquid

Methodology Applied
Scientific EffectAbsorption: Absorption (physical)

AI summary

A device for treating strand-shaped textile goods in the form of a circulating strand of fabric has a treatment container (1), a transport device which puts the strand of fabric (7) into circulation, a cutting-off device and a fabric storage device (6) for temporarily receiving the cut-off fabric strand. The goods store has a storage area (49) for the strand of goods fed in by the transport device, which is laterally delimited all around by storage walls (46, 47, 48), of which one storage wall (48) is transverse to the direction of transport of the strand of goods fed in and in or can be adjusted counter to the direction of transport in a predetermined alignment with the opposite storage wall (47).
