Filament Winding Guide Radial Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In filament winding, fiber bundles often interfere with each other and fiber supplying guides due to oblique drawing and winding, leading to potential fiber breakage and degradation of the reinforcement layer's strength.
Innovation Solution
A filament winding apparatus with a controller that adjusts the radial position of fiber supplying guides to maintain a specific distance from the central axis, ensuring that fiber bundles from different guide units do not intersect, thereby preventing interference during helical winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple fiber supplying guides are arranged radially to simultaneously wind multiple fiber bundles, then productivity is improved, but fiber bundle interference occurs causing fiber breakage and degradation of reinforcement layer strength
Solution Approach 1:
The patent applies the dynamics principle by making the radial positions of fiber supplying guides adjustable rather than fixed. The control unit dynamically changes the radial positions of fiber supplying guides in the first and second guide units based on the winding direction and position, allowing the system to adapt and prevent fiber bundle interference while maintaining high productivity through simultaneous multi-bundle winding.
2Manufacturing precision
If fiber bundles are drawn out obliquely from fiber supplying guides during helical winding, then winding position is achieved, but fiber bundles may cross between guide units causing interference
Solution Approach 1:
The patent applies the feedback principle through the control unit that receives information about the winding direction and position, and based on this feedback, adjusts the radial positions of fiber supplying guides. This closed-loop control ensures that fiber bundles are guided precisely to avoid crossing between guide units while maintaining the required winding position accuracy.
Solution Approach 2:
The patent applies the parameter changes principle by modifying the radial position parameter of fiber supplying guides based on winding conditions. The control unit changes this parameter dynamically to prevent fiber bundle crossing, ensuring that the oblique drawing of fiber bundles does not lead to interference between different guide units.

AI summary
To provide a filament winding apparatus that prevents a fiber bundle supplied to a liner from interfering with other fiber bundles and fiber supplying guide. A first guide unit 43 and a second guide unit 44 including a plurality of fiber supplying guides 80A and 80B arranged radially and moving in a direction approximately perpendicular to a central axis Ra of a liner 1, a driving unit 60 configured to change a radial position of the fiber supplying guides 80A and 80B, and a controller C configured to control the driving unit 60 are provided. When a fiber bundle F supplied from the fiber supplying guide 80A crosses between the fiber supplying guide 80B and the liner 1, the controller C makes the distance from the fiber supplying guide 80B to the central axis Ra of the liner 1 larger than the distance from the fiber supplying guide 80A to the central axis Ra of the liner 1, and in the reverse case, the controller makes the distance from the fiber supplying guide 80A to the central axis Ra of the liner 1 larger than the distance from the fiber supplying guide 80B to the central axis Ra of the liner 1.
