Roller Wear Measurement Assembly for Predictive Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to accurately diagnose and forecast the wear of rotating rollers in machines, leading to inefficient maintenance, increased downtime, and economic losses, particularly in bottling machines where worn rollers cause inaccurate operation and performance degradation.
Innovation Solution
A contactless sensor system measures the distance of a roller-supporting component to detect wear, using inductive sensors and predictive algorithms to forecast when rollers need replacement, allowing for simultaneous maintenance and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the diameter of rollers is measured periodically at predetermined intervals, then wear detection is achieved, but time and labor are wasted
Solution Approach 1:
The patent applies preliminary action by continuously monitoring roller wear through sensors that detect position variations of the fork supporting the rollers. Instead of periodic measurements, the system proactively detects wear in real-time during machine operation, enabling early intervention before excessive wear occurs. This transforms reactive periodic measurement into proactive continuous monitoring, eliminating idle measurement time while maintaining high detection accuracy.
2Reliability
If rollers are replaced when worn, then machine accuracy is maintained, but machine downtime and maintenance costs increase
Solution Approach 1:
The patent implements feedback by continuously monitoring the position of the fork supporting the rollers and comparing it against reference values. When wear causes position deviations beyond predetermined thresholds, the system generates alerts and forecasts remaining useful life. This feedback loop enables condition-based maintenance, allowing operators to schedule roller replacement optimally - neither too early (wasting productivity) nor too late (compromising reliability). The forecasted remaining life information specifically helps plan maintenance during natural downtime, maximizing machine availability while maintaining accuracy.
3Loss of time
If multiple rollers are replaced simultaneously based on wear forecasting, then total downtime is reduced, but measurement and forecasting complexity increases
Solution Approach 1:
The patent applies universality by using a single sensor system and control unit to monitor multiple rollers across different rods simultaneously. The same measurement principle (detecting fork position variations) and forecasting algorithm are universally applied to all rollers in the machine. This multi-functional approach allows the system to generate comprehensive wear forecasts for numerous rollers using one integrated measurement assembly, enabling coordinated replacement of multiple rollers in a single maintenance event without proportionally increasing system complexity.

AI summary
A measurement assembly for measuring wear of the surface of revolution of rotating members is provided. The assembly comprises a support structure, a rod having a first sliding movement along a direction having a rectilinear component with respect to the support structure, a cam guide having a second relative movement with respect to the sliding rod, and at least one roller rotatably fixed to the sliding rod and in rolling contact with a corresponding track of the cam guide. The second relative movement between the cam guide and the sliding rod causes the first movement of the rod along the sliding direction. The measurement assembly may comprise an indicator of the position of the at least one roller along the rectilinear component such that the indicator is capable of generating an electrical signal indicative of the distance between the indicator and the roller.
