Solution Overview

Problem

Existing textile machine sleeve magazines are limited in their ability to store multiple types of sleeves and efficiently remove individual or multiple sleeves simultaneously, often requiring separate magazines and devices for each type.

Innovation Solution

A method and sleeve magazine design featuring multiple transport elements, each holding a specific type of sleeve, with a controller to selectively move holders to a removal point for targeted removal by a single removal device, allowing for flexible storage and retrieval of different sleeve types without the need for separate magazines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate sleeve magazines are used to store different types of sleeves, then each sleeve type can be stored separately, but the device complexity and cost increase

Engineering Contradiction:
Improveability to store multiple sleeve typesVSAvoidnumber of sleeve magazines and removal devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sleeve storage functions into a single sleeve magazine by dividing it into multiple transport elements (first, second, third transport elements), each capable of carrying different sleeve types. This merging approach reduces the total number of separate magazines and removal devices needed, thereby decreasing device complexity while maintaining the ability to store and manage multiple sleeve types efficiently

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single removal device is designed with universal functionality to remove sleeves from any of the multiple transport elements within the sleeve magazine. This multi-functional design allows one removal device to serve multiple purposes and access different sleeve types, eliminating the need for separate removal devices for each sleeve type and reducing overall system complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If a single removal device is used for multiple transport elements, then device complexity is reduced, but the ability to selectively remove specific sleeves may be compromised

Engineering Contradiction:
Improvenumber of removal devicesVSAvoidselective removal capability
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The sleeve magazine is segmented into multiple independent transport elements (first, second, third transport elements), each with its own holders for sleeves. This segmentation allows the single removal device to selectively access and remove sleeves from specific transport elements by controlling which transport element positions a holder at the removal point, thereby maintaining selective removal capability while using only one removal device

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transport elements are designed to be movable, allowing dynamic positioning of holders at the removal point. The controller can independently control each transport element to bring the desired holder containing the required sleeve type to the removal point, enabling selective removal of specific sleeves while using a single removal device, thus maintaining ease of operation without increasing device complexity

Inventive Principle:
Principle #15Dynamics

AI summary

A sleeve magazine for a textile machine and operational method include multiple transport elements each with a plurality of holders configured for holding a sleeve, wherein each transport element is driven to move the holders and sleeves to a removal point. A removal device at the removal point removes the sleeves from the holders. A controller controls movement of the individual transport elements such that the holder of at least one transport element is moved with the sleeve thereon to the removal point. The controller actuates the removal device to remove the sleeve from the holder at the removal point while the holders of the remaining transport elements are maintained outside of the removal point so as not to interfere with removal of the sleeve from the holder at the removal point.
