Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing take-up winding apparatuses face challenges with yarns vibrating and becoming entangled due to twisting and/or vibration caused by the suction gun, making the threading operation difficult and time-consuming, often requiring multiple operators.
Innovation Solution
A method and apparatus that involves a third roller being brought into contact with the yarns between the suction gun and the yarn path guide to regulate yarn paths, preventing the propagation of twisting and/or vibration, allowing a single operator to efficiently thread the yarns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the suction gun generates high-speed air flow to improve yarn suction forces, then the yarn suction capability is improved, but the yarns experience twisting and vibration that propagate upstream causing entanglement
Solution Approach 1:
A third roller is introduced as an intermediary element between the suction gun and the second yarn path guide. This roller receives the twisted and vibrating yarns from the suction gun and regulates them before they reach the yarn path guide, preventing the propagation of harmful vibrations upstream while maintaining the high-speed air flow suction capability.
Solution Approach 2:
The harmful twisting and vibration are extracted from the yarn path by using the third roller to isolate and regulate the yarns at a specific point. The roller separates the problematic section (between suction gun and yarn path guide) from the rest of the yarn path, preventing entanglement propagation.
2Productivity
If the plurality of yarns are drawn in at high speed using the suction gun, then the productivity is improved, but the threading operation becomes difficult due to yarn vibration and entanglement
Solution Approach 1:
The third roller serves as a mediator that enables high-speed yarn drawing while maintaining threading operability. It regulates the yarns immediately after they are drawn by the suction gun, preventing vibration propagation that would otherwise make threading difficult, thus allowing high productivity without sacrificing ease of operation.
3Productivity
If a single operator performs the threading operation, then the labor efficiency is improved, but the operation becomes difficult due to yarn vibration and entanglement
Solution Approach 1:
The third roller enables a single operator to perform threading efficiently by regulating the yarns at a critical point. It prevents the vibration and entanglement that would otherwise require multiple operators, thus improving productivity while maintaining ease of operation for a single person.

AI summary
[Object] Object of the invention is providing yarn threading method of take-up winding apparatus, the take-up winding apparatus, and suction gun which make decrease entanglement between yarns and vibration and make good for take-up yarns. [Solution means Purpose] A method for threading to a take-up winding apparatus using a suction gun includes regulating yarn paths for a plurality of yarns using a first roller 21 or a first yarn path guide 22 of the take-up winding apparatus. Between the suction gun 61 and a second roller or a second yarn path guide 23 of the take-up winding apparatus, a third roller 24 is brought into contact with the yarns Y. The second roller and the second yarn path guide 23 are on a downstream side relative to the first roller 21 and the first yarn path guide 22. With the third roller 24 in contact with the yarns Y, the yarns Y are fed onto the second roller or the second yarn path guide 23. After the yarns are fed onto the second roller or the second yarn path guide 23, the third roller 24 is brought out of contact with the yarns Y.
