Modular Creel Adapters for Textile Winding Format Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices for textile machines are limited in their ability to efficiently produce cross-wound bobbins of different formats and widths, requiring complex adjustments and changes in the creel when switching tube formats, which leads to increased downtime and operational inefficiencies.
Innovation Solution
A winding device with a modular creel system that uses interchangeable adapters of varying lengths, allowing quick fixation of cheese tubes of different lengths and formats, and a software-adjustable thread traversing device to accommodate various bobbin formats without the need for extensive reconfiguration, minimizing downtime and adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If winding devices are designed for a specific cross-wound bobbin format, then high traversing speeds can be achieved, but the device can only wind bobbins with a certain width
Solution Approach 1:
The creel is divided into modular components including interchangeable adapters that can be quickly swapped to accommodate different tube formats. The thread guide drum is also segmented with adjustable components that can be reconfigured for different bobbin widths, allowing the system to maintain high traversing speeds while adapting to various formats.
Solution Approach 2:
The winding device incorporates dynamically adjustable components such as the thread guide drum position and angle, which can be modified during operation or between jobs. The creel arms and tube clamps are designed to be adjustable rather than fixed, enabling the system to adapt to different bobbin formats without sacrificing traversing speed performance.
2Adaptability or versatility
If tube format is changed in existing winding devices, then different bobbin widths can be produced, but complex adjustments and creel changes are required
Solution Approach 1:
Interchangeable adapters are pre-configured for specific tube formats and lengths, allowing operators to simply swap the adapter rather than perform complex adjustments. The creel components are designed with pre-set positions and quick-release mechanisms that eliminate the need for time-consuming reconfiguration when changing tube formats.
Solution Approach 2:
The creel and thread guide system are designed with universal components that can accommodate multiple tube formats through simple adapter changes. The thread guide drum and traversing mechanism are configured to work with various bobbin widths using the same basic structure, reducing the need for format-specific adjustments.
3Adaptability or versatility
If tube format is changed in existing winding devices, then different bobbin formats can be produced, but downtime increases due to reconfiguration
Solution Approach 1:
Adapters are pre-configured and ready for quick installation, eliminating the need for time-consuming adjustments during format changes. The creel components are designed with quick-release mechanisms that allow rapid swapping of adapters and tube clamps, minimizing downtime when transitioning between different bobbin formats.
Solution Approach 2:
The creel system is segmented into independently interchangeable components including adapters, tube clamps, and guide elements. This modular design allows operators to change only the necessary components for a format switch rather than reconfiguring the entire creel, significantly reducing changeover time.
4Adaptability or versatility
If complex adjustments are made for format changes, then different bobbin formats can be accommodated, but operational efficiency decreases
Solution Approach 1:
Adapters and creel components are pre-configured for specific formats, allowing operators to simply install the appropriate adapter rather than perform complex adjustments. This preliminary preparation of interchangeable parts maintains operational efficiency while accommodating different bobbin formats.
Solution Approach 2:
The system incorporates dynamically adjustable components that can be quickly reconfigured for different formats without requiring complex manual adjustments. The thread guide drum position, angle, and other critical parameters are designed to be easily modified, maintaining high productivity across different format productions.

AI summary
The coil winder (4) has a coil frame for holding rotatably supported bobbin cases, and rotating devices (9, 33) for rotating the bobbin cases and/or cross-wound bobbins (5). A separately driven thread traversing device (10) traverses a thread (16) accumulating on the bobbins. The traversing device is designed such that traversing stroke is changed to produce different bobbin formats. The frame is modified by mounting with adapters of different length such that the cases of different length and different formats are fixed between coil frame arms.
