Rolling Mill Sensor Detects Fiber Band Irregularities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling mills for slivers face challenges in detecting operational irregularities efficiently, as current monitoring systems require high control technology efforts and cannot reliably detect deviations across the width of the rollers, leading to potential sliver jams or breaks.
Innovation Solution
A rolling mill design featuring at least one fixed roller and one adjustable roller, mounted in left and right frames, equipped with a sensor that detects operational irregularities across the width, allowing for simultaneous monitoring of roller position and sliver jams, eliminating the need for proximity switches and ground contacts, and enabling detection of small deviations with a single sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors (one per frame side) are used to monitor operational irregularities, then monitoring coverage is improved, but device complexity and control effort increase
Solution Approach 1:
The patent combines multiple monitoring functions into a single sensor system. One sensor mounted on the frame monitors both the relative position between frames and the presence of fiber strips across the entire rolling mill width, replacing what would traditionally require multiple sensors per frame side.
Solution Approach 2:
The single sensor performs multiple functions: detecting relative frame position, monitoring fiber strip presence, and identifying operational irregularities across the full width of the rolling mill, making it a multi-functional monitoring solution.
2Measurement precision
If sensors are positioned to detect deviations across the width of the rolling mill, then detection precision is improved, but control technology effort increases
Solution Approach 1:
The sensor is positioned to sequentially detect different sections across the width of the rolling mill as the fiber strip passes through, dividing the monitoring task into temporal segments rather than requiring simultaneous multi-point measurement.
Solution Approach 2:
The fiber strip itself acts as an intermediary that carries information about positional deviations across the width to the single sensor, which detects irregularities as they pass by during the rolling process.
3Reliability
If traditional monitoring systems with multiple sensors are used, then comprehensive monitoring is achieved, but cost-effectiveness decreases
Solution Approach 1:
The patent merges multiple monitoring functions into a single sensor system, reducing component costs and simplifying installation while maintaining comprehensive monitoring coverage across the rolling mill width.
Solution Approach 2:
The single sensor performs multiple monitoring tasks including frame position detection and fiber strip presence monitoring across the entire width, providing comprehensive coverage at lower cost than multiple specialized sensors.
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
This solution simplifies the control system, reduces the number of sensors required, and allows for the detection of small deviations across the roller width, preventing sliver jams and breaks, while being adaptable to different roller widths and suitable for retrofitting various machine types.
Implementation Method 1
The sensor is designed as a light barrier and can therefore be easily adapted to the different widths of the roller arrangements
