Swinging Fiber Bundle Guide Roller for Twisting Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber bundle guides cause twisting and inaccurate winding of flat fiber bundles due to variations in tensile force, leading to shifting and contact with guide roller flanges, resulting in shrinking or bending.
Innovation Solution
A fiber bundle guide with a cylindrical guide roller that swings in response to widthwise changes in the fiber bundle's traveling path, featuring a rotatably supported guide roller with an eccentric swinging shaft and an angle indicating member, allowing for stable rotation and adjustment to prevent excessive shifting and twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional guide roller with flanges is used to guide the fiber bundle, then the fiber bundle is constrained within the guide roller, but the variation in tensile forces causes the fiber bundle to shift toward the flange side, resulting in shrinking, bending, and twisting of the fiber bundle
Solution Approach 1:
The guide roller is designed to swing dynamically in response to widthwise changes in the fiber bundle's traveling path. The support member allows the guide roller to rotate about a swinging shaft, enabling automatic adjustment to compensate for tensile force variations and prevent fiber bundle shifting and twisting.
Solution Approach 2:
The guide roller automatically adjusts its position through the swinging mechanism without external control. The variation in tensile forces directly causes the guide roller to swing, creating a self-regulating system that prevents fiber bundle distortion.
2Adaptability or versatility
If the guide roller is fixed in position, then the structure is simple and stable, but it cannot respond to widthwise changes in the fiber bundle traveling path, causing excessive shifting and twisting
Solution Approach 1:
The guide roller transitions from a fixed position to a dynamically adjustable position through the swinging shaft mechanism. The support member enables the guide roller to rotate and swing, providing adaptability to path changes while maintaining structural simplicity.
Solution Approach 2:
The swinging mechanism provides automatic feedback response to widthwise changes in the fiber bundle path. When the fiber bundle shifts, the guide roller automatically swings to correct the position, creating a closed-loop control system without external sensors or actuators.

AI summary
A fiber bundle guide (1) includes a cylindrical guide roller (11), a support member (12) which rotatably supports the guide roller (11), and a movable mechanical section (13) arranged between the guide roller (11) and the support member (12), so that the guide roller (11) swings in response to widthwise changes in the traveling path of the fiber bundle (Y). According to this fiber bundle guide, it is possible to prevent excessive shifting of the fiber bundle (Y) toward one of both sides of the circumferential edge of the guider roller (11), preventing shrinking or bending of the fiber bundle (Y) due to the contact of the fiber bundle (Y) to the flange (112) of the guide roller (11), which makes it possible to guide the fiber bundle (Y) without causing twisting of the bundle.
