Treatment unit for in-line treatment of thread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thread consuming devices, such as embroidery machines, face challenges in achieving accurate in-line treatment of threads due to heavy vibrations during operation, which complicates the application of treatments like coloring using multiple nozzles.
Innovation Solution
A stand-alone treatment unit with adjustable support arrangements and nozzles configured to dispense coating substances onto moving threads, featuring a housing, thread guiding devices, and a control unit for precise operation, allowing for in-line treatment without mechanical connection to the vibrating stage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If in-line treatment apparatus is integrated with thread consuming device, then treatment capability is provided, but vibration from moving stage degrades treatment accuracy
Solution Approach 1:
The treatment unit is separated from the thread consuming device into an independent stand-alone unit. This segmentation allows the treatment unit to operate independently without being affected by vibrations from the moving stage, while still providing in-line treatment capability. The treatment unit can be positioned close to the thread path but maintains mechanical independence.
Solution Approach 2:
A support arrangement acts as an intermediary between the treatment unit and the thread consuming device. This intermediary provides adjustable positioning and mechanical decoupling, allowing the treatment unit to be precisely positioned for accurate treatment while being isolated from vibrations generated by the moving stage during embroidery operation.
2Manufacturing precision
If nozzle is positioned close to thread for accurate treatment, then treatment precision is improved, but vibration from moving stage causes misalignment
Solution Approach 1:
The treatment unit is extracted from the moving stage assembly and placed on an independent support arrangement. This extraction removes the treatment unit from the source of vibrations, allowing the nozzle to be positioned close to the thread for precise treatment without experiencing the alignment instability caused by stage movements during embroidery operation.
Solution Approach 2:
The support arrangement provides preliminary positioning and stabilization of the treatment unit before treatment begins. The adjustable support allows precise initial alignment between the nozzle and thread path, and this alignment is maintained throughout operation because the treatment unit is mechanically decoupled from the vibrating moving stage.
3Productivity
If treatment unit is integrated with thread consuming device, then in-line treatment is achieved, but vibration transmission reduces treatment quality
Solution Approach 1:
By segmenting the treatment unit from the thread consuming device while maintaining close proximity through independent positioning, the system achieves in-line treatment efficiency without the penalty of vibration transmission. The treatment unit processes thread in-line but operates in a mechanically stable environment separate from the moving stage.
