SLX-290
Enhance sorting efficiency and reduce errors with the SLX-290, a solution for high-speed item classification and advanced barcode reading.
Prevent sorting mistakes and protect order accuracy
Quality checks are vital in logistics sorting, serving as safeguards that ensure each order is correctly picked, packed, and routed before it leaves the facility. By catching errors early—whether through manual inspections or automated systems—quality checks help prevent mis-sorts and improve overall order accuracy. The result is less costly rework and returns and a lighter workload for customer service teams, all while maintaining sorter throughput.
Ultimately, strong quality control measures are essential for balancing speed and reliability in logistics operations. Incorporating automated quality control solutions that use item detection technology into order fulfillment and sorting processes helps your team maintain the delicate balance of speed and reliability that defines excellence in today’s competitive market.
General-purpose vision systems aren’t up to the challenge of monitoring sorting operations
Sorting in logistics operations can be based on destination, carrier requirements, delivery speed, or packaging constraints. To support this range of sorting and maintain traceability from order placement to final shipment, machine vision systems play a vital role. These solutions automatically verify item details, detect misplacements, and confirm label accuracy in real time — reducing human error and ensuring each package is correctly routed without slowing down throughput.
Maintaining high detection accuracy becomes more difficult as sorters wear down and accumulate dust, dirt, and old labels. General-purpose machine vision systems often struggle in these environments, especially when faced with challenges like:
- Overhanging items: Objects that are not centered on sorter trays run an increased risk of falling off the tray and becoming “lost” – causing shipping delays.
- Varying tray types: Incorporating machine vision solutions across different tray types and characteristics may require complex re-programming
- Hygiene issues: Dirt, debris, or labels stuck on sorter trays increase the risk of false positive detections (detecting something that isn’t actually there), resulting in delays
- Low contrast environments or small, clear, and reflective products: When objects blend in with their surroundings, they can appear invisible to detection systems, which prevents reliable detection.
Traditional systems can be costly to maintain, require custom programming, and often work only with specific types of sorters. Manual visual checks are not overly accurate, as the human eye can't reliably find these types of errors at high line speeds.
Overhanging items can cause shipping delays.
Transparent objects can be difficult to detect, and dirty or worn trays can cause false positives.
Enhance logistics sorting efficiency with Cognex 2D and 3D item detection
Cognex AI-powered 2D vision systems, such as the SLX-290, simplify detection tasks using pre-trained AI models for fast deployment and reliable performance.
Designed for easy integration into your sorting process, this advanced technology accurately detects the presence or absence of items across various sorting systems, making it ideal for implementing quality control steps within your sorting process.
The 3D-A1000 Item Detection System is a better fit for situations that require more advanced functionality, such as:
- Capturing and reporting item location data
- Monitoring sorting environments with low contrast between objects on the tray and the tray itself
- Splitting a carrier into two zones, with each zone having its own detection conditions and status output
- Detecting object overhangs and reporting specific error codes
These systems offer several key capabilities to optimize logistics operations:
- Item detection: Detect items across belts, trays, or totes – even when objects vary in material, color, or orientation. These solutions tolerate common sorter hygiene issues like dirt, dust, and spots, and catch overhanging items or empty trays, helping reduce no-reads, double counts, misroutes, and skewed inventory.
- Order verification: Combine object detection with dimensional data to verify pick accuracy, adding a robust layer of validation beyond barcode scans. This reduces rework and boosts fulfillment accuracy in fast-paced, high-volume environments.
With support always within reach from a global network of experts and self-service resources, logistics teams can stay ahead of demand, optimizing order accuracy and delivering on brand promise.
