Combing Machine Upper Gripper Clutch for Automated Ecartement Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combing machines face challenges in automating the setting of the upper tong opening, which is crucial for adjusting the Ecartement and ensuring proper combing cycles.
Innovation Solution
The implementation of a clutch device in the driving connection of the pliers shaft allows for temporary decoupling of the upper pliers from the rest of the combing head, enabling precise adjustment of the upper tong opening without the need for manual apprenticeship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual adjustment of the upper tong opening is used, then the Ecartement can be adjusted, but the adjustment process is complex and requires manual intervention
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated system using a motor-driven sprocket and chain mechanism. The motor automatically adjusts the upper tong opening by rotating the sprocket, which moves the chain, thereby positioning the upper gripper at the desired opening without manual intervention.
Solution Approach 2:
The system enables self-adjustment through automatic detection and control. The control unit monitors the combing process parameters and automatically actuates the motor to adjust the upper tong opening, allowing the machine to regulate itself without external manual operation.
2Adaptability or versatility
If the upper gripper is permanently connected to the gripper shaft, then the combing cycle is stable, but the Ecartement cannot be adjusted
Solution Approach 1:
The patent introduces a dynamic, adjustable connection between the upper gripper and gripper shaft. The temporary coupling device allows the connection to be established or released as needed, enabling the system to adapt between fixed and adjustable states. This dynamic capability permits Ecartement adjustment while maintaining operational stability during the combing cycle.
Solution Approach 2:
The driving connection is segmented into separable components: the gripper shaft, the temporary coupling device, and the upper gripper. This segmentation allows the upper gripper to be temporarily decoupled for adjustment and then reconnected for stable operation, providing both adjustability and reliability.
3Manufacturing precision
If the coupling device is used to decouple the upper gripper, then the opening position can be adjusted, but the combing cycle is interrupted
Solution Approach 1:
The coupling device is designed to be temporarily engaged and disengaged in periodic cycles. During normal operation, the coupling is engaged for stable combing. When adjustment is needed, the coupling is temporarily disengaged, the adjustment is made, and then the coupling is re-engaged, allowing precise positioning with minimal interruption to overall productivity.
