Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spinning machines experience interruptions leading to unsuitable yarn ends that cause delays in the piecing process, as existing methods require manual or robotic intervention to locate and remove these ends, which is time-consuming.
Innovation Solution
A spinning machine with a yarn end removal system integrated between the spinning device and winding device, allowing for immediate separation and removal of unsuitable yarn ends during the spinning process, utilizing a suction channel and cutting unit to manage the yarn end, reducing the need for manual or robotic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual or robotic intervention is used to locate and remove yarn ends, then the yarn end removal can be performed, but the spinning process is significantly delayed due to the time required for service robots to move to affected spinning stations
Solution Approach 1:
The yarn end discharge device is pre-positioned at each spinning station to automatically discharge yarn ends as soon as they are formed, eliminating the delay of waiting for service robots to arrive. The device is ready in advance to handle yarn ends without requiring subsequent manual or robotic intervention.
Solution Approach 2:
Each spinning station is equipped with its own yarn end discharge device that automatically handles yarn end removal without external assistance. The system serves itself by having localized discharge mechanisms at each station that operate independently, eliminating the need for centralized robotic intervention.
2Productivity
If yarn ends are wound onto the rotating bobbin of the winding device, then the yarn production continues, but the yarn ends become difficult to access and require detachment from the bobbin surface using suction devices
Solution Approach 1:
The yarn end discharge device extracts yarn ends directly from the spinning point before they get wound onto the bobbin. By removing the yarn ends at the source, the system prevents them from becoming embedded on the bobbin surface, making them easily accessible for discharge without requiring suction devices to retrieve them later.
Solution Approach 2:
The yarn end discharge device acts as an intermediary between the spinning point and the winding device. It intercepts yarn ends in the intermediate space between these two components, preventing them from reaching the bobbin surface while maintaining continuous yarn production.
3Ease of manufacture
If service robots are used to remove end sections of yarn, then the removal can be performed, but the process is time-consuming as robots must first move to the area of affected spinning points
Solution Approach 1:
Instead of using a centralized robotic system that must travel between stations, the invention segments the yarn end discharge function and places dedicated discharge devices at each spinning station. This segmentation allows each station to handle its own yarn ends independently and immediately, eliminating robot travel time.
Solution Approach 2:
Each spinning station becomes self-sufficient with its own yarn end discharge device, eliminating the need for external robotic assistance. The system serves itself by having localized automatic discharge mechanisms that operate independently at each station without requiring centralized control or physical movement between stations.
