LG CNS Multi-Level Shuttle (MLS)

This application case features the implementation of the LG CNS Multi-Level Shuttle (MLS) system.

The Multi-Level Shuttle is a high-efficiency, "Light Version" shuttle AS/RS (Automated Storage and Retrieval System) based on LG CNS's proprietary technology. By employing two shuttles operating in sync within the same aisle, it achieves over 1.6 times higher productivity than traditional single-shuttle systems. Furthermore, its modular design allows for horizontal and vertical expansion, much like LEGO blocks.

Unlike conventional AS/RS systems that require large-scale installation and high investment costs, the MLS minimizes floor space by sharing shuttle travel paths across racks configured in two or more rows. This allows for installation in much tighter spaces. Its simple, module-based design is realized through the use of lightweight forming racks.

As an advanced shuttle system with built-in collision avoidance, it enables real-time storage and high-speed inbound/outbound processing while maximizing space efficiency through shared aisle technology.

Workflow

STEP 1.	Goods arriving at the logistics center are transported via the inbound conveyor.
STEP 2.	The MLS picker automatically loads and stores the products arriving from the conveyor.
STEP 3.	The shuttle picker performs real-time picking according to outbound order requests.
STEP 4.	Picked items are loaded onto the outbound conveyor.
STEP 5.	Products moving along the outbound conveyor are dispatched from the logistics center to their final destinations.
