Yarn supplying bobbin feeding device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing yarn supplying bobbin feeding devices face inefficiencies in power consumption and production efficiency due to continuous suction source operation during intermittent yarn bobbin supply, leading to wasteful power usage and potential production delays.
Innovation Solution
A yarn supplying bobbin feeding device with a yarn end cutting device that includes a suction member connected to a suction source via a communication path, featuring an opening/closing member to switch between supply and non-supply states of negative pressure, reducing power consumption by adjusting the suction vent's operation based on yarn supply continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction source operates continuously to maintain negative pressure for sucking yarn ends, then the yarn ends can be captured effectively, but power consumption increases wastefully during interrupted yarn supply
Solution Approach 1:
The suction source operates periodically rather than continuously. The control unit activates the suction source only during periods when yarn supplying bobbins are supplied to the vibration feeder, and deactivates it during interruption periods. This periodic operation maintains yarn end capture reliability when needed while eliminating wasteful power consumption during idle periods.
Solution Approach 2:
The control unit monitors the supply state of yarn supplying bobbins to the vibration feeder and uses this feedback information to control the suction source operation. When yarn supply is detected, the suction source is activated; when supply is interrupted, the suction source is deactivated. This feedback mechanism ensures the suction source operates only when necessary, resolving the contradiction between reliability and energy consumption.
2Use of energy by moving object
If the suction source power is turned on/off manually to match yarn supply intervals, then power consumption is reduced, but time and effort are wasted and production efficiency may decrease
Solution Approach 1:
The control unit automatically controls the suction source operation based on the detected yarn supply state without requiring manual intervention. The system self-adjusts the suction source activation and deactivation timing according to the yarn supply interruptions, eliminating the time and effort that would be spent on manual control while maintaining optimal power consumption levels.
Solution Approach 2:
The manual mechanical control of the suction source is replaced with an automated control system that uses sensors and control logic to monitor yarn supply status and activate/deactivate the suction source accordingly. This substitution eliminates manual operation time and effort while improving production efficiency through automated, timely control actions.

Function Achieved in This Case
