Weaving Machine Shed-Forming Device Reference Position Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting the coupling positions of a shed-forming device in weaving machines is complex and requires knowledge of the driving device and transmission mechanism, often leading to incorrect settings and weaving faults, especially when dealing with non-linear relationships between heald frame amplitudes and coupling positions.
Innovation Solution
Providing perceptible indications for reference coupling positions on the drive levers, allowing operators to set coupling positions without knowledge of the driving device or transmission mechanism, using visual cues like different shapes, colors, or symbols to facilitate correct adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators adjust coupling positions using traditional methods without visual indications, then the adjustment process requires extensive knowledge of driving devices and transmission mechanisms, but this leads to incorrect settings and weaving faults
Solution Approach 1:
The drive lever itself provides the setting information through integrated visual indications (scale markings and reference marks). The system serves itself by embedding the measurement reference directly on the component being adjusted, eliminating the need for external tables or complex calculation procedures.
Solution Approach 2:
The patent uses visual color-coded or pattern-coded indications on the drive lever scale and reference marks. Different colors or patterns indicate different reference coupling positions for various heald frames, providing immediate visual feedback to operators without requiring technical knowledge of the underlying mechanics.
2Measurement precision
If detailed tables and calculations are provided for coupling positions, then measurement precision improves, but the device complexity and operator burden increase
Solution Approach 1:
The patent extracts the essential measurement information from complex calculation tables and embeds it directly on the drive lever as simplified visual scale markings and reference marks. This extraction transforms complex tabular data into intuitive visual indicators that can be read directly during operation.
Solution Approach 2:
The visual indications on the drive lever serve as an intermediary between the complex transmission mechanism and the operator. Instead of requiring operators to understand the complex relationship between driving device position and heald frame amplitude, the reference marks and scale provide a direct visual mapping that simplifies the interface.
3Reliability
If coupling positions are adjusted without visual reference marks, then the transmission mechanism design remains simple, but the reliability of shed formation decreases due to incorrect settings
Solution Approach 1:
The reference coupling position markings are pre-calculated and pre-marked on the drive lever during manufacturing. This preliminary action embeds the correct setting information directly on the component, ensuring that operators can achieve accurate shed formation without requiring complex real-time calculations or adjustments.
4Adaptability or versatility
If multiple heald frames require different coupling positions, then the adaptability of the system improves, but the difficulty of detecting and measuring correct positions increases
Solution Approach 1:
The patent segments the scale markings and reference marks on the drive lever to correspond to different heald frames. Each heald frame has its own designated reference mark and scale section, allowing operators to easily identify and set the correct coupling position for each specific heald frame without confusion.
