Yarn Threading Robot Dynamic Suction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn threading technologies face instability due to inadequate control of suction force, leading to issues like yarn swaying, breakage, or failure in properly threading onto elements, as the suction force is either too small or too large.
Innovation Solution
A yarn threading robot equipped with a controller to adjust the suction force of a sucking retaining unit using compressed fluid, allowing for precise control through an electro-pneumatic regulator, ensuring optimal tension during yarn threading processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the suction force of the suction gun is increased to prevent yarn swaying, then yarn stability is improved, but yarn tension becomes too high causing breakage
Solution Approach 1:
The suction force is made dynamically adjustable during the yarn threading process. The controller changes the suction force according to the specific threading stage and yarn type, transitioning from a static suction force system to a dynamic one that adapts to process requirements.
Solution Approach 2:
The suction force parameter is changed based on threading process requirements. The controller adjusts the suction force magnitude according to different threading stages and yarn characteristics, optimizing the balance between yarn stability and preventing excessive tension.
2Strength
If the suction force of the suction gun is decreased to reduce yarn tension, then yarn breakage is prevented, but yarn swaying occurs causing threading failure
Solution Approach 1:
The suction force is made dynamically adjustable during the yarn threading process. The controller changes the suction force according to the specific threading stage and yarn type, transitioning from a static suction force system to a dynamic one that adapts to process requirements.
Solution Approach 2:
The suction force parameter is changed based on threading process requirements. The controller adjusts the suction force magnitude according to different threading stages and yarn characteristics, optimizing the balance between yarn stability and preventing excessive tension.
3Device complexity
If constant suction force is applied throughout the threading process, then system simplicity is maintained, but threading reliability decreases due to inability to adapt to different stages
Solution Approach 1:
The suction force is made dynamically adjustable during the yarn threading process. The controller changes the suction force according to the specific threading stage and yarn type, transitioning from a static suction force system to a dynamic one that adapts to process requirements.
Solution Approach 2:
The suction force parameter is changed based on threading process requirements. The controller adjusts the suction force magnitude according to different threading stages and yarn characteristics, optimizing the balance between yarn stability and preventing excessive tension.
