Automated Bobbin Removal System for Yarn Winding Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn winding equipment requires manual intervention to remove defective bobbins from the transportation path, which is time-consuming and can lead to operational stoppages if not performed promptly, especially when the tray becomes full.
Innovation Solution
A bobbin processing device with automated removal and sorting capabilities, utilizing a transportation path, removing section, and control section that determines and acts on status and yarn quality information to automatically remove defective bobbins and manage their sorting without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual removal of defective bobbins is performed, then operational stoppages are prevented, but productivity decreases due to time-consuming manual operations
Solution Approach 1:
The system performs self-service by automatically detecting defective bobbins through sensors and removing them using a robotic arm, eliminating the need for manual intervention and maintaining continuous operation without productivity loss
Solution Approach 2:
The patent replaces manual mechanical removal with an automated robotic system that uses sensors for detection and a robotic arm for removal, substituting human labor with automated mechanical systems to maintain both reliability and productivity
2Productivity
If automated removal system is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The automated system is segmented into distinct functional modules: defect detection sensors, control unit, and robotic removal mechanism. This modular segmentation allows each component to perform its specific function independently, managing complexity through functional decomposition
Solution Approach 2:
The control unit serves as an intermediary between the sensor detection system and the robotic removal mechanism, processing sensor data and coordinating the removal action. This intermediary layer manages system complexity by centralizing control logic
3Ease of operation
If defective bobbins are not removed promptly, then manual labor is reduced, but operational stoppages occur when trays become full
Solution Approach 1:
The automated removal system operates continuously alongside the winding process, promptly removing defective bobbins as they are detected. This ensures continuous operation by preventing tray overflow while minimizing manual labor through automated intervention

AI summary
A bobbin processing device (3) for a yarn winding system configured to receive bobbins from and transfer bobbins to a spinning machine (2) and/or a winding machine (4), comprises a transportation path (10) along which the bobbins can move through the bobbin processing device, optionally on a bobbin transport tray (T) a removing section (42) configured to remove a bobbin (B) from the transportation path, optionally from the bobbin transport tray; and a bobbin processing control section (11) that is configured to control the removing section to remove a bobbin from the transportation path in dependence on at least one of quality information linked to the bobbin, yarn amount information linked to the bobbin and status information linked to the bobbin. Further described is a yarn winding/processing system optionally with the bobbin processing device and a bobbin processing method optionally using the bobbin processing device.
