Movable Cover Unit for Textile Winding Station Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of winding stations in textile machines producing cross-wound bobbins makes cleaning difficult, especially when thread ends need to be sought and connected, leading to inefficiencies and potential damage to the bobbins.
Innovation Solution
A modular design with a cover unit that moves between working and cleaning positions, incorporating a suction nozzle with a movable suction port and drive mechanism, allows for easier access and automation of the cleaning process while minimizing contact with the bobbin surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thread seeking device and multiple components are added to the winding station to enable thread end detection and connection, then the thread continuity is ensured, but the cleaning difficulty increases
Solution Approach 1:
The winding station is divided into a base unit and a cover unit that can be separated. The cover unit contains the thread seeking device and can be removed to provide access to the base unit for cleaning purposes, thus maintaining thread continuity functionality while enabling easy cleaning.
Solution Approach 2:
The cover unit is designed to be movable between a working position (covering the base unit during operation) and a cleaning position (removed or opened to expose internal components). This dynamic configuration allows the system to switch between operational and cleaning states, resolving the contradiction between maintaining thread seeking capability and enabling easy cleaning.
2Ease of operation
If the cover unit is made movable to facilitate cleaning, then cleaning access is improved, but the device complexity increases
Solution Approach 1:
The winding station is segmented into a base unit and a cover unit that can be easily separated. This segmentation allows the cover to be removed for cleaning without requiring complex mechanisms, as the separation interface is designed to be simple and straightforward.
Solution Approach 2:
Instead of making the internal components movable for cleaning access, the solution inverts the approach by making the cover itself movable (removable). This simplifies the overall structure, as moving the outer cover is mechanically simpler than moving internal threading components.

AI summary
A winding station of a textile machine for producing cross-wound bobbins includes a base unit, a cover unit, and a bobbin holder configured to hold the cross-wound bobbin. A traversing device is configured to lay a thread in a crosswise manner on the cross-wound bobbin. A thread finding device is configured to find a thread end on the cross-wound bobbin. The base unit at least partially covers the cover unit, and the cover unit is movable with respect to the base unit between a working position for laying the thread and seeking the thread end and a cleaning position for cleaning the winding station. At least portions of the thread finding device are configured on the cover unit. A method is also provided for operating the winding station.
