Automatic Ring Yarn Spindle Stopper with Magnetic Brake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ring yarn machines lack a system to immediately stop the spindle upon yarn breakage, leading to unnecessary machine operation, increased yarn breakages due to flying cotton, and inefficiencies that require additional operators and reduced production speeds.
Innovation Solution
An automatic spindle stopper utilizing a magnetic field coil, inserting metal, locking mechanism, and stopping arm to mechanically lock the spindle, triggered by a breakage sensor detecting reduced traveller speed, ensuring immediate cessation of spindle rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the spindle continues revolving after yarn breakage, then the machine operates continuously, but yarn production is lost and additional breakages occur due to flying cotton
Solution Approach 1:
The invention implements a feedback mechanism where a sensor detects yarn breakage (through traveller speed reduction) and automatically triggers the electromagnetic valve to activate the brake, stopping the spindle. This closed-loop control eliminates the need for continuous operator monitoring and prevents waste by immediately halting operation upon breakage detection.
Solution Approach 2:
The system performs self-service by automatically detecting breakage and activating the stopping mechanism without human intervention. The electromagnetic valve and brake system work autonomously to stop the spindle, eliminating the need for operators to manually monitor and stop each breakage event.
2Reliability
If operators manually stop spindles, then breakages can be addressed, but additional operators are required and production speed decreases
Solution Approach 1:
The automatic stopper system performs the breakage management function autonomously without requiring operator intervention. The sensor-actuator-brake system handles detection and stopping automatically, eliminating the need for additional operators and maintaining high production speeds while ensuring reliable breakage management.
Solution Approach 2:
The invention replaces the manual mechanical stopping method (operators using knee or hand brakes) with an automated electromechanical system. The electromagnetic valve actuates the brake through a mechanical linkage, substituting human physical intervention with an automated control system that maintains reliability while preserving production speed.
3Loss of time
If the electromagnetic valve activates the brake immediately, then the spindle stops promptly, but the system complexity increases
Solution Approach 1:
The electromagnetic valve serves as an intermediary component between the sensor detection system and the brake mechanism. It converts the electrical signal from the sensor into mechanical actuation of the brake, providing a simple and reliable interface that achieves prompt stopping without requiring complex direct coupling between the sensor and brake systems.
4Productivity
If operators work overtime to handle increased breakages, then machine efficiency can be maintained, but labor costs increase
Solution Approach 1:
The automatic stopper system eliminates the need for additional labor to handle increased breakages by autonomously detecting and responding to breakage events. This self-service capability maintains machine efficiency at high speeds without requiring operators to work overtime, thereby reducing labor costs while preserving productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents additional yarn breakages, increases machine efficiency, reduces operator requirements, and minimizes production losses by promptly stopping the spindle upon yarn breakage, allowing for faster operation and cost savings.
Implementation Method 1
Magnetic field consists of coiled part (2) exterior part of the coiled part (3) rear box which covers the magnetic field coil (5) and a cover (4). In order to make magnetic field, the coiled part is covered by wires. Magnetic field coil makes magnetic field in order to give movement to the inserting metal to (6).
Implementation Method 2
The working principle of inserting metal (6) is to move forward and backward inside the magnetic field. When there is a magnetic field, the inserting metal (6) is pulled inside by this magnetic field to make the stopping arm (7) work.
