Yarn Threading Robot Swing Suppression via Rail Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operational robot in a spun yarn winding system that moves along a single rail member tends to swing in the axial direction, causing interference and hindrance during yarn threading, and existing solutions to suppress this swing often result in increased vertical size or require additional components, leading to space constraints and increased costs.
Innovation Solution
A textile machine design that includes a swing suppressor with a regulatory portion and a state switching unit, which contacts a fixed portion, such as the rail member, to restrict unwanted swing in the orthogonal direction without extending below the floor surface, thus maintaining a compact vertical profile and reducing costs by utilizing the rail member as the fixed portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a positioning mechanism extending to the floor surface is used to suppress swing, then swing suppression is improved, but the vertical size of the operational robot increases
Solution Approach 1:
The swing suppressor redirects the stabilization mechanism from the vertical dimension (extending to floor) to the horizontal dimension (extending laterally to contact the rail member). This allows swing suppression without increasing vertical size, as the regulatory portion contacts the rail member sideways rather than reaching down to the floor.
Solution Approach 2:
Instead of creating a new floor-based positioning mechanism, the invention uses the existing rail member structure as the reference point for swing suppression. The regulatory portion of the swing suppressor contacts the rail member, effectively using the rail's position and structure to provide stabilization without requiring additional vertical space.
2Stability of the object's composition
If additional positioning components are added to suppress swing, then swing suppression is improved, but device complexity and cost increase
Solution Approach 1:
The rail member serves dual functions: it provides the guide path for the operational robot's movement and simultaneously serves as the fixed reference structure for swing suppression. The regulatory portion contacts this existing structure, eliminating the need for separate positioning components and reducing overall device complexity.
Solution Approach 2:
The existing rail member structure serves its own guidance function while also providing the reference structure needed for swing suppression. The system uses its own existing components (the rail member) to achieve additional functionality (swing suppression) without requiring external or additional specialized components.

AI summary
Increase in size in the vertical direction of an operational robot is avoided, and swing of the operational robot while a working unit is in operation is suppressed. A spun yarn take-up machine includes take-up units which are aligned in a predetermined direction orthogonal to the vertical direction, a single rail member 35 which is fixedly provided at a position remote from the floor surface and extends along the predetermined direction, and a yarn threading robot 4 which moves while being suspended from the rail member 35. The yarn threading robot 4 includes a main body 31, a moving unit 34 configured to move the main body 31, a working unit which is configured to perform yarn threading while the moving unit 34 is stopped, and a swing suppressor 40 which is configured to suppress swing of the main body 31 in an orthogonal direction which is orthogonal to both the vertical direction and the predetermined direction. One of the swing suppressor 40 and the rail member 35 includes a V-shaped block 41 which is positioned to sandwich the other one of the rail member 35 and the swing suppressor 40 at least in the orthogonal direction, while the working unit is in operation.
