Ring Spinning Machine Traversing Drive Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring spinning machines lack design flexibility, particularly for longer machines, as they are restricted by central drives and cannot accommodate multiple independent traversing devices, limiting the placement and configuration of traversing devices.
Innovation Solution
The traversing device is driven by the infeed bottom roller, allowing it to be positioned anywhere on the machine and connected via a chain or belt, enabling independent operation of multiple devices along the machine's length, with roving guide rails equipped with funnels for better guidance and a cam mechanism for movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the traversing device is connected to a central intermediate drive, then the machine structure is simplified, but the design flexibility and adaptability are reduced
Solution Approach 1:
The patent segments the drive system by connecting traversing devices to the infeed bottom roller rather than using a centralized intermediate drive. This allows multiple independent traversing devices to be distributed along the machine length, with each device independently controllable. The segmentation enables different sections of the machine to have customized traversing configurations without being constrained by a single central drive mechanism.
2Adaptability or versatility
If the traversing device is connected to the infeed bottom roller, then the design flexibility and adaptability are improved, but the device complexity increases
Solution Approach 1:
The infeed bottom roller serves multiple functions: it feeds the roving to the drafting system and simultaneously acts as the drive source for the traversing device. This multi-functionality reduces the need for separate drive mechanisms, thereby limiting the increase in device complexity while maintaining high design flexibility. The universal use of the infeed bottom roller simplifies the overall system architecture.
3Adaptability or versatility
If multiple traversing devices are distributed along the machine, then the adaptability for longer machines is improved, but the device complexity increases
Solution Approach 1:
The patent divides the traversing function into multiple independent devices distributed along the machine length, each connected to its local infeed bottom roller. This segmentation allows longer machines to have customized traversing coverage in different sections, improving adaptability while keeping each individual traversing device relatively simple in structure.
Solution Approach 2:
Each traversing device is locally connected to the infeed bottom roller at its specific position along the machine. This local connection allows each section to be optimized independently for its specific requirements, with traversing devices placed only where needed rather than uniformly across the entire machine, thereby managing complexity effectively.
4Ease of operation
If the roving is fed evenly at one point, then the feeding process is simplified, but the roller wear increases
Solution Approach 1:
The patent implements a dynamic traversing mechanism that moves the roving feed point along the infeed bottom roller during operation. This dynamic movement distributes the mechanical stress and wear across different sections of the roller over time, preventing concentrated wear at a single location while maintaining a relatively simple feeding process through automated traversal control.
