Solution Overview
Problem
Existing measuring rollers for determining flatness deviations in strip-shaped products, particularly metal strips, face challenges in precision and simplicity, as temperature conditions affect force measurement signals, leading to inaccuracies in detecting flatness deviations.
Innovation Solution
The proposed measuring roller incorporates a first and second temperature sensor arranged at different radial distances from the longitudinal axis, allowing for temperature difference measurement to correct force measurement signals and determine prestress changes, enhancing the detection of flatness deviations with improved precision and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are arranged at the same radial distance from the longitudinal axis, then the device structure is simple, but temperature-induced variations in force signals cannot be corrected, reducing measurement precision
Solution Approach 1:
The patent applies local quality by arranging temperature sensors at different radial distances from the longitudinal axis of the measuring roller. Specifically, at least one temperature sensor is positioned at a first radial distance while another is positioned at a second radial distance, allowing each sensor to measure temperature at its specific location. This enables the system to capture radial temperature gradients within the measuring roller, which is essential for correcting force measurement signals affected by temperature variations, thereby improving flatness deviation measurement precision without excessive structural complexity.
2Reliability
If multiple temperature sensors at different radial distances are used, then temperature correction of force signals is possible, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by utilizing temperature sensors positioned at different radial distances to detect temperature variations within the measuring roller. The system uses these temperature measurements to dynamically adjust or correct the force measurement signals, compensating for temperature-induced effects such as thermal expansion or material property changes. This approach enhances the reliability of force measurements by accounting for temperature parameters, ensuring accurate flatness deviation detection even under varying thermal conditions.

Implementation Method 1
a first temperature sensor, which is located at a first distance in the radial direction from the longitudinal axis of the measuring roller is arranged remotely, and a second temperature sensor, which is arranged at a second distance different from the first distance in the radial direction from the longitudinal axis
Implementation Method 2
the way in which the force applied to the outer surface of the measuring roller is conducted through the measuring roller in such a way that it can be recorded by the sensor to generate a measurement signal dependent on this force can depend on the temperature conditions

AI summary
The measuring roll (4) has a longitudinal axis and a sensor arranged in a recess of the measuring roll. The sensor is provided for generating a measuring signal depending on a force applied on an outer surface of the measuring roll. A first temperature sensor is arranged at a first distance in a radial direction away from the longitudinal axis. A second temperature sensor is arranged in a second distance different from the first distance in the radial direction away from the longitudinal axis. An independent claim is included for a method for determining flatness deviations of a band-like material.
