Yarn Piecing Guidance System for Ring Spinning Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In textile spinning plants, workers face challenges in efficiently identifying and responding to yarn breaks across multiple ring type spinning machines due to distance limitations, leading to wasted time and potential delays in addressing yarn breaks, and existing systems can cause misidentification of yarn break indicators.
Innovation Solution
A ring type spinning machine apparatus equipped with yarn break sensors, motion sensors, and a control system that uses large lamps and blinking LED indicators to guide workers to the exact spindle with a yarn break, prioritizing the machine with the most breaks or closest to the worker, reducing unnecessary movement and improving response efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indicator lamps are provided for each spindle to indicate yarn breaks, then the worker can identify the location of yarn breaks, but the worker cannot recognize the indicator lamp from a long distance due to the longer machine frame
Solution Approach 1:
The patent introduces a hierarchical indication system that adds a spatial dimension to the notification. Instead of relying solely on small lamps at spindle level, large-area display panels are mounted on the machine frame to provide macroscopic visual cues. This multi-scale approach allows workers to detect yarn breaks from a distance while maintaining precise location identification capability.
Solution Approach 2:
The indication system is segmented into multiple levels: individual spindle indicator lamps provide precise location identification, while large-area display panels divided into regions corresponding to different spindle blocks provide distant visibility. This segmentation allows each component to fulfill its specific function optimally without compromise.
2Measurement precision
If working lamps are provided for each spindle to indicate yarn breaks, then the worker can identify the position of the spinning machine, but another worker may erroneously recognize the lamp illumination as a yarn break indicator and move to the wrong location
Solution Approach 1:
Different regions of the large-area display panel are assigned different visual characteristics or colors to distinguish between yarn break indications and other operational statuses. This local differentiation ensures that workers can immediately recognize the specific meaning of each illuminated region, preventing misidentification and erroneous responses.
Solution Approach 2:
The system dynamically adjusts the indication mode based on the situation. When yarn breaks occur, the large-area display panel highlights the affected regions with distinctive patterns or colors that differ from normal operational indicators. This dynamic differentiation enhances reliability by making the distinction between actual yarn breaks and other conditions visually unambiguous.
3Measurement precision
If the worker moves around the spinning machines to check for indicator lamps, then the worker can identify yarn breaks, but time is wasted and yarn break remediation is delayed
Solution Approach 1:
The large-area display panels are pre-positioned at locations easily visible to workers approaching the spinning machines. This preliminary arrangement of information eliminates the need for workers to search for indicator lamps, allowing them to immediately identify yarn break locations upon arrival and proceed directly to remediation, significantly reducing response time.
