Swingable Suction Gun for False-Twist Texturing Yarn Threading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false-twist texturing machines face difficulties in properly threading yarns due to the laborious process of adjusting and fixing a suction gun to the yarn running path, which can lead to deformation of the holder and improper engagement of the sucking unit.
Innovation Solution
A false-twist texturing machine design featuring a suction gun with a hook member that swings by its own weight to engage the sucking unit with the yarn running path, eliminating the need for firm fixation and allowing easy adjustment, along with a guider and tapered design for reliable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction gun is fixed to a holder, then the suction gun can be positioned for yarn threading, but the holder is deformed by forcibly moving the suction gun and fine adjustment is laborious
Solution Approach 1:
The suction gun is designed to be swingable about the hook member rather than fixed, allowing dynamic adjustment of position. The gravity-based swinging mechanism enables easy repositioning while maintaining reliable engagement during operation.
Solution Approach 2:
The suction gun uses its own weight to automatically swing into the correct position for engagement with the yarn running path outlet, eliminating the need for manual fine adjustment or external forcing that would deform a holder.
2Reliability
If the suction gun is firmly fixed to ensure proper engagement, then threading can be performed, but the structure becomes complex and adjustment is difficult
Solution Approach 1:
The fixation function is segmented from the suction gun body and performed by a separate hook member, which simplifies the overall structure. The hook member provides reliable engagement without requiring complex fixation mechanisms attached to the suction gun itself.
Solution Approach 2:
The hook member acts as an intermediary between the suction gun and the mounting structure, providing a simple yet reliable connection point that enables both easy attachment and reliable engagement without complex fixation structures.
3Device complexity
If the suction gun is not properly fixed, then the structure is simple, but the sucking unit is not engaged with the outlet of the yarn running path
Solution Approach 1:
The suction gun automatically positions itself for proper engagement by swinging about the hook member under its own weight, ensuring reliable engagement without requiring complex fixation structures or external positioning mechanisms.
Solution Approach 2:
The position of the suction gun changes dynamically as it swings about the hook member, transitioning from an unengaged position to a properly engaged position where the sucking unit aligns with the yarn running path outlet.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and reliable yarn threading by allowing the suction gun to be hooked onto a single hook member, reducing component count and preventing holder deformation, while ensuring smooth and certain engagement with the yarn running path outlets.
Implementation Method 1
when a hooking portion provided in the suction gun is hooked on the at least one hook member, the suction gun is swung about the at least one hook member by the weight of the suction gun

AI summary
An object of the present invention is to achieve easy yarn threading to a yarn running path by means of a suction gun, the yarn running path being formed in a heater of a false-twist texturing machine. A false-twist texturing machine 1 configured to false-twist a yarn includes: a heater 19 in which a yarn running path 30 is provided, a yarn running in the yarn running path 30; a suction gun 50 used for threading the yarn to the yarn running path 30; and a hook member 40 on which the suction gun 50 is hooked to be swingable. As a hooking portion 54 provided in the suction gun 50 is hooked on the hook member 40, the suction gun 50 is swung about the hook member 40 by its own weight so that a sucking unit 51 provided at a leading end of the suction gun 50 is engaged with an outlet portion 32 of the yarn running path 30.
