LG CNS Smart Logistics Equipment: Cross Belt Sorter

Industry > LogisticsApplication > LogisticsSector > Logistics

This application case features the implementation of LG CNS’s Cross Belt Sorter.

The LG CNS Cross Belt Sorter is a high-end, high-performance system incorporating proprietary technologies such as Automatic Recovery and Vision-based Re-Centering. Developed entirely with domestic Korean technology, it stands as a premier solution for high-speed logistics.

The Cross Belt Sorter consists of a chain of independently operated short conveyor belt carriers mounted transversely along a main track. This loop-type system rotates at high speeds, discharging goods to the left or right at their designated destinations. Notably, it holds the world’s first innovation record for food material sorting centers, proving its ability to stably transport and sort not only standard boxes but also various types of irregular (non-standard) goods with high performance and safety.

Components

Robot	Robot: Cross Belt Sorter Handling Weight: Max 50kg / Min 0.1kg Max Item Dimensions: W700 x L1400 x H700 mm Min Item Dimensions: W50 x L100 x H2 mm Tray Belt Size: W400 x L450 x H500 mm (Weight: 600kg) Max Tray Capacity: Up to W800 x L800 x H1200 mm (Weight: 1200kg) Tray Pitch: W600 x L650 x H700 mm (Weight: 800kg) Track Speed: 170m/min Operating Temperature: -5°C to +40°C

Workflow

STEP 1.	Goods merge at ultra-high speeds in the Induction Section using inverter synchronous control.
STEP 2.	Goods are transported and sorted along the Track and Cart Sections.. If a mis-sorted item is detected, the Automatic Recovery process is initiated.
STEP 3.	Sorted goods are discharged through the Chute Section.
