Movable Weft Feeder with Stroboscopic Insertion-Zone Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weaving machines lack effective machine-mounted lighting solutions for enhancing visibility during weft thread insertion, which is crucial for proper operation and safety, and existing hand-held lights complicate the process and pose safety risks.
Innovation Solution
A device with a built-in light source, preferably stroboscopic, is integrated into the weaving machine to illuminate the weft insertion zone, allowing for safe and efficient visual inspection of weft thread insertion processes without requiring additional mounting structures, and can be adjusted for optimal illumination and synchronized with the weaving frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If hand-held lights are used to illuminate the weft insertion zone, then visibility is improved, but safety risks increase and the process becomes more complicated
Solution Approach 1:
The light source is integrated directly into the weft feeder element, merging the illumination function with the existing threading mechanism. This eliminates the need for separate hand-held lights and ensures the light source moves with the weft feeder element to the presenting position, providing consistent illumination while improving safety through machine-mounted integration.
2Illumination intensity
If additional mounting structures are added to the weaving machine for lighting, then illumination is provided, but device complexity increases
Solution Approach 1:
The light source is integrated into the existing weft feeder element structure, utilizing the already-present mounting mechanisms. This approach provides illumination without requiring additional separate mounting structures, thereby avoiding increased device complexity while still achieving the lighting objective.
3Stability of the object's composition
If the light source is fixed on the weaving machine, then illumination is stable, but adaptability to different weaving widths is reduced
Solution Approach 1:
The light source is mounted on the movable weft feeder element rather than being fixed to the machine frame. This dynamic mounting allows the light source to move with the weft feeder element to the presenting position, adapting to different weaving widths while maintaining stable illumination during the threading operation through its fixed position relative to the weft thread guide.
4Ease of operation
If the weft feeder element is positioned for easy threading access, then ease of operation improves, but illumination of the insertion zone may be compromised
Solution Approach 1:
The light source moves with the weft feeder element to the presenting position, ensuring the insertion zone remains illuminated during threading operations. This dynamic positioning maintains illumination intensity while the weft feeder element is positioned for easy operator access, resolving the contradiction between operational ease and illumination quality.
