Increasing Demands in Modern Intralogistics
In modern intralogistics systems, the demands for availability, speed, and process reliability are continuously increasing. Automated conveying and sorting systems such as Hard Pouch Sorters play a critical role in ensuring efficient material flow.
Even a single defective component can significantly impact the entire system performance. As a result, unplanned downtime, reduced throughput, and high maintenance effort remain major operational challenges.
To address these issues, predictive maintenance for Hard Pouch Sorters becomes a key enabler for stable and efficient operations.
Track and Roll: AI-Based Condition Monitoring for Shuttle Systems
With Track and Roll, an advanced predictive maintenance solution for Hard Pouch Sorters is available for shuttle system within the ferag.skyfall platform.
The system uses existing sensor data and AI-driven analytics to detect abnormal or potentially defective shuttles at an early stage — before critical failures occur.
Key outcomes:
- Higher system availability
- Reduced downtime
- Data-driven predictive maintenance
- Improved process reliability
Importantly, no additional sensors are required. The solution integrates directly into existing infrastructures using PLC logs and operational data.
The Challenge: Wear and Tear in Hard Pouch Sorter Systems
Hard Pouch Sorters and shuttle-based overhead conveyor systems operate under continuous load and high throughput conditions. Over time, this inevitably leads to mechanical wear and performance degradation.
Typical operational challenges:
- Increasing mechanical wear
- Rising number of system disruptions
- Declining system performance
- Higher maintenance workload
- Overloaded maintenance teams
Impact of defective shuttles:
Even a single faulty shuttle can disrupt the entire material flow, causing:
- Jammed carriers in switches
- Shuttle blockages in singulation modules
- System stoppages (e.g. Skytrain interruptions)
- Damaged or broken components
- Unplanned downtime
In most cases, maintenance is performed reactively — only after a failure occurs. This increases costs and reduces system availability.
Predictive Maintenance Instead of Reactive Maintenance
Track and Roll enables a shift from reactive to predictive maintenance.
The system continuously monitors the entire shuttle fleet within ferag.skyfall, identifying early signs of degradation before failures occur.
Core advantage:
No additional hardware or sensors are required.
The solution is fully based on existing PLC data and sensor signals.
This allows seamless integration into existing intralogistics environments.
How AI-Based Condition Monitoring Works
The system analyzes continuously collected shuttle movement data across multiple sections of the conveyor system.
This creates a highly reliable statistical foundation, which is processed using machine learning and data science methods.
1. Data Collection from Existing Systems
Existing sensors and PLC logs provide continuous operational data for each shuttle.
Collected data includes:
- Transit times
- Route behavior
- Timing deviations
- Statistical anomalies
This ensures a cost-efficient and hardware-free implementation.
2. Calculation of Condition Indicators
From the collected data, multiple condition indicators are calculated for each shuttle.
These indicators describe the technical behavior of the shuttle and allow early detection of performance deviations.
Even minor changes can indicate early-stage wear or potential failure.
3. Aggregation into a Health Score
All condition indicators are combined into a single Health Score per shuttle.
Additionally, a confidence level is calculated to indicate the reliability of the assessment.
This enables operators to:
- Quickly assess shuttle condition
- Prioritize maintenance actions
- Evaluate data reliability
4. AI-Based Defect Detection
Machine learning models and threshold-based analytics identify shuttles with a high probability of failure.
The system detects statistical outliers — shuttles whose behavior significantly deviates from normal operating patterns.
This enables early defect detection before system-critical failures occur.
Intuitive Visualization for Operational Decision-Making
All results are displayed in an intuitive dashboard designed for maintenance teams and operators.
Key information includes:
- Health Score per shuttle
- Confidence level of analysis
- Defect probability
- Priority ranking of critical shuttles
This ensures fast interpretation and supports data-driven maintenance decisions.
Flexible Maintenance Strategies
A major advantage of Track and Roll is its flexibility.
Thresholds and evaluation criteria can be adapted to different operational strategies:
1. Precise Defect Detection
Focus on individual shuttles with high failure probability.
2. Preventive Monitoring
Early detection of wear patterns across the entire fleet.
3. Peak Load Preparation
Planned maintenance before seasonal peaks or high-throughput periods.
Shuttles identified as critical can be automatically or manually removed from the material flow and sent to maintenance stations.
Benefits of AI-Based Predictive Maintenance
The combination of AI, existing sensor data, and intelligent visualization delivers significant advantages of predictive maintenance for Hard Pouch Sorters.
