Replaceable Hoop Winding Device for Continuous Filament Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filament winding apparatuses face inefficiencies due to the need to interrupt and restart the winding operation when fiber bundles around bobbins become scarce, resulting in significant downtime and reduced production efficiency.
Innovation Solution
A replaceable hoop winding device system that allows for quick swapping of hoop winding devices by separating and re-coupling a liner supporting shaft, enabling continuous operation with minimal interruption, and utilizing rails for efficient movement and positioning of hoop winding devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If bobbins are replaced when fiber bundle becomes scarce, then the fiber bundle supply is restored, but the winding operation is interrupted for a considerable time
Solution Approach 1:
The invention divides the winding system into multiple independent hoop winding devices (first hoop winding device and second hoop winding device) that can operate independently. When one device needs maintenance or bobbin replacement, the other can continue operating, segmenting the production process to eliminate complete shutdowns.
Solution Approach 2:
The invention implements a system where used bobbins are quickly removed and replaced with fresh ones on standby hoop winding devices. The system recovers productivity by having备用 (standby) devices ready to immediately take over when primary devices need maintenance or bobbin changes.
2Loss of time
If hoop winding device is replaced by separating liner supporting shaft, then the replacement time is reduced, but the system complexity increases
Solution Approach 1:
The liner supporting shaft is divided into multiple sections with coupling mechanisms that allow it to be separated into segments. This segmentation enables the hoop winding device to be removed and replaced without moving the entire liner supporting shaft, significantly reducing replacement time despite adding coupling mechanisms.
Solution Approach 2:
The coupling mechanism on the liner supporting shaft is designed to be dynamically separable and reconfigurable. The coupling can be quickly disconnected and reconnected to accommodate different hoop winding devices, providing operational flexibility and reducing downtime while managing system complexity through standardized interfaces.
3Productivity
If multiple hoop winding devices are mounted on one rail, then the replacement efficiency is improved, but the space requirement increases
Solution Approach 1:
Multiple hoop winding devices are arranged along the length of a single rail in a linear configuration, utilizing the longitudinal dimension of the available space. This allows multiple devices to be positioned sequentially on one rail without requiring additional parallel rails, improving replacement efficiency while managing spatial requirements through optimized linear arrangement.

AI summary
A filament winding apparatus includes a hoop winding device mounted with bobbins that supply a fiber bundle. Each of the bobbins is whirled around a periphery of a liner to wind the fiber bundle around an outer peripheral surface of the liner. The hoop winding device is replaceable with another hoop winding device at a predetermined position.
