Introduction
Conveyors are the backbone of modern manufacturing and logistics operations. They continuously move raw materials, semi-finished parts, and finished goods across production floors, assembly lines, and warehouses. However, like any mechanical system, conveyors are prone to wear, misalignment, belt damage, spillage, and roller failures. A minor issue such as belt deviation or material buildup can lead to major production downtime, safety hazards, or product losses if not detected early.
Intelgic offers an AI-driven Conveyor Health Monitoring System that uses industrial cameras, laser displacement sensors, and profile sensors to continuously monitor the physical and operational condition of conveyor systems. By combining advanced imaging with intelligent analytics, the system provides real-time insights, predictive maintenance alerts, and complete visibility into the health of conveyor belts, rollers, pulleys, and frames.
The Need for Conveyor Health Monitoring
Traditional maintenance of conveyor systems relies heavily on periodic manual inspections. These inspections are often reactive—issues are detected only after failure occurs. This reactive approach results in:
- Unplanned downtime due to sudden mechanical failure
- Inconsistent inspection quality because of human error
- Higher maintenance costs and spare part consumption
- Safety risks caused by unnoticed belt tears or roller misalignments
To overcome these challenges, a continuous, contactless, and intelligent monitoring system is needed—one that can detect faults at an early stage and provide actionable insights before breakdowns occur.
Intelgic’s Vision-Based Conveyor Health Monitoring Solution
Intelgic’s system integrates Machine Vision, Laser Profiling, and AI analytics to inspect, monitor, and analyze conveyor performance in real time. The system architecture includes:
High-Resolution Industrial Cameras
Mounted strategically above and along the conveyor line, these cameras continuously capture visual images of the belt and roller surfaces. Using specialized lighting—such as line lights, backlights, or coaxial lights—the system ensures uniform illumination for detecting:
- Belt surface cracks, cuts, and wear patterns
- Cracks, chips and any other defects on conveyor components
- Defects on chains, wheels, wire management etc.
- Foreign objects or spillage
- Skewing or misalignment of the belt
- Damaged joints or fasteners
Intelgic’s Live Vision AI software processes these images frame by frame to identify anomalies automatically and classify the type of defect detected.
Laser Displacement Sensors
Laser sensors measure the displacement, misalignment or vibration of conveyor components with micron-level precision. They can monitor:
- Vertical or horizontal misalignment and displacement of the conveyor components such as belts, magnets, wheels, and other components.
- Surface smoothness.
- Roller eccentricity and wobbling
- Belt sagging or uneven tension
- Surface profile variation of the belt
These measurements are fed into Intelgic’s data acquisition module and correlated with the camera-based inspection results for higher accuracy.
Profile Sensors (2D/3D Laser Profilers)
Profile sensors create a 3D surface map of the conveyor and belt using a laser line projected across the surface. By analyzing this 3D profile, the system can detect:
- Deformation or swelling in the belt
- Accumulation of materials or carryback
- Uneven roller heights or bent idlers
- Sidewall wear and edge deformation
Profile sensors provide a complete geometric representation of the conveyor surface and structure, complementing the visual data from cameras.
AI-Powered Data Processing and Analytics
All data captured by cameras and sensors are processed in a GPU-based industrial computer running Intelgic’s Live Vision AI software. The AI models analyze temporal and spatial patterns to:
- Detect early-stage belt and roller defects
- Trend wear progression over time
- Trigger predictive maintenance alerts
- Correlate sensor data with operating parameters like load, speed, and temperature
A comprehensive dashboard displays conveyor health indicators such as:
- Belt wear index
- Alignment score
- Roller vibration level
- Belt edge condition
- Overall conveyor health rating
This data can be integrated into the existing PLC, MES, or SCADA systems, allowing the maintenance and production teams to view real-time alerts and plan maintenance activities accordingly.
