Solution Overview
Problem
Existing thread traversing devices for textile machines producing cross-wound bobbins are prone to increased maintenance and cleaning efforts due to exposure to textile dust and fiber fly, leading to issues with traversing width stability and operational efficiency.
Innovation Solution
A thread traversing device with a toothed belt guided over deflection wheels featuring smooth running surfaces and guide rings, combined with a highly elastic and wear-resistant toothed belt, ensures self-cleaning and maintains the predetermined traversing width without additional cleaning efforts, using a stepper motor controlled via a control computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the toothed belt is guided over deflection wheels with toothing, then the belt is securely driven, but fiber residues and dirt settle in the toothing areas requiring frequent cleaning
Solution Approach 1:
The patent converts the harmful effect of fiber accumulation by designing the deflection wheels with smooth running surfaces that prevent fiber entanglement. The toothed belt's own motion becomes the cleaning mechanism, as its teeth scrape against the smooth deflection wheel surfaces, automatically removing accumulated fibers and dirt without external cleaning interventions.
Solution Approach 2:
The system achieves self-cleaning functionality where the toothed belt's movement through the housing automatically removes fiber residues from the deflection wheels. The smooth running surfaces of the deflection wheels facilitate this self-cleaning effect, eliminating the need for separate cleaning mechanisms or frequent manual maintenance.
2Adaptability or versatility
If the thread traversing device is exposed to textile dust and fiber fly, then it can operate in the winding mill environment, but maintenance and cleaning efforts increase significantly
Solution Approach 1:
The patent employs a largely closed housing that encloses the toothed belt and deflection wheels, creating a protective barrier against textile dust and fiber fly in the winding mill environment. This housing design allows the device to operate in harsh conditions while minimizing contamination of the internal components.
Solution Approach 2:
The smooth running surfaces of the deflection wheels convert the harmful effect of fiber accumulation into a beneficial self-cleaning mechanism. As the toothed belt moves through the housing, its teeth scrape against the smooth deflection wheel surfaces, automatically removing any fibers that manage to enter the housing, thereby reducing maintenance requirements.
3Productivity
If the traversing speed is increased to improve productivity, then more bobbins can be produced, but the traversing width stability decreases due to fiber accumulation
Solution Approach 1:
The self-cleaning design enabled by smooth deflection wheel surfaces allows the toothed belt to maintain consistent tension and positioning even at high traversing speeds. The automatic removal of fiber residues prevents the belt from slipping or deviating, thereby maintaining traversing width stability throughout high-speed operation.
Solution Approach 2:
The smooth running surfaces of the deflection wheels transform the potential problem of fiber accumulation into a self-cleaning mechanism that operates continuously during high-speed traversing. This ensures that the toothed belt maintains precise positioning and consistent traversing width even at increased speeds that would normally cause rapid fiber buildup.
