Yarn Winding Device Lever Mechanism for Variable Traverse Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding devices lack the ability to freely change winding width and form packages with steps, as they require attachment and detachment of restriction guides to alter winding width, limiting the flexibility in creating packages with varying widths and steps.
Innovation Solution
A yarn winding device with a lever member that moves between restriction and non-restriction positions to guide the yarn to different traverse grooves on the traverse drum, allowing for adjustable winding widths and the formation of stepped packages by alternating between wide and narrow winding widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a restriction guide is attached to change the winding width, then the winding width can be restricted, but it requires attachment and detachment operations which reduces flexibility and productivity
Solution Approach 1:
The guide lever is designed to be movable between a non-restriction position and a restriction position, allowing dynamic adjustment of the winding width without attachment or detachment operations. This dynamic mechanism enables quick switching between different winding widths, improving both flexibility and productivity while maintaining precise control over the winding process.
2Adaptability or versatility
If the winding width is fixed, then the device structure is simple, but it cannot form packages with steps or vary winding width
Solution Approach 1:
The guide lever moves between non-restriction and restriction positions to dynamically adjust the winding width. This simple dynamic mechanism enables the formation of packages with steps and provides versatility in winding width adjustment without significantly increasing device complexity.
3Adaptability or versatility
If the lever member guides yarn to different traverse grooves, then winding width flexibility is improved, but the yarn path becomes more complex
Solution Approach 1:
The guide lever dynamically positions the yarn at different points along the traverse drum circumference, guiding it to different traverse grooves. This dynamic positioning system provides freedom in winding width setting while using a simple mechanical movement rather than a complex multi-component guidance system.

AI summary
To improve freedom of setting change in the winding width in the yarn winding device. In a yarn winding device, a first guide member 63 is configured to move between a non-restriction position at which the lever member 63 does not restrict a movable position of the yarn 4 in a rotational axis direction of the traverse drum 5 to guide the yarn to the traverse drum 5 with a predetermined traverse width, and a restriction position at which the first lever member 63 restricts the movable position of the yarn 4 in the rotational axis direction of the traverse drum 5 to supply the yarn 4 to the traverse drum 5 with a traverse width narrower than the predetermined traverse width, thereby guiding the yarn to different traverse grooves of the traverse drum between the restriction position and the non-restriction position, wherein yarn winding operation with different widths are repeated to perform a step forming winding or a yarn winding operation with a traverse width narrower than the predetermined width is continuously effected to perform a yarn winding with a traverse width narrower than the predetermined traverse width.
