Fully Unmanned Truck Unloading: Inside the Asian Elephant System at China Tobacco Binzhou

Truck unloading is one of the last manual bottlenecks in many warehouses — irregular stacking, varying carton sizes, and uneven truck floors make it hard to automate reliably. At China Tobacco Binzhou's front storage area, BlueSword deployed a fully unmanned system built around its Asian Elephant intelligent loading and unloading robot, running end-to-end from truck to shelf.

From Truck to Storage, One Connected System

The system centers on BlueSword's intelligent robotic truck loading and unloading robot, integrated with barcode scanning, posture adjustment, carton conveying, robotic palletizing, automatic pallet destacking, and AGV transport — together automating unloading, scanning, palletizing, and inbound/outbound handling for carton goods without manual intervention. The core loading and unloading robot itself is built from five modules: a telescopic conveyor, mobile chassis, intermediate conveyor, vision inspection system, and end-effector.

Speed and Adaptability Inside the Truck

3D vision recognition identifies the condition, quantity, and orientation of cartons inside the truck and determines the optimal picking sequence, and a dedicated dual-carton gripper reaches unloading rates of 800–900 cartons per hour. The system handles cartons from 200–800mm in any dimension, up to 50kg each, and its tracked chassis stays stable on uneven truck floors with a maximum climbing angle of 8°.

It adapts automatically to enclosed trucks 7.6 meters and longer, with a lifting platform that aligns to different vehicle compartment heights, and operates across a -5°C to 40°C range at 10–90% humidity — a working range built for real dock conditions, not just controlled environments.

One Machine, Multiple Docks

A single unit can switch between multiple loading bays, reducing the capital investment needed compared with dedicated equipment per dock, and the telescopic conveyor adjusts both length and height to integrate with upstream and downstream systems while minimizing floor space. With minor hardware changes, the same machine can switch between loading and unloading — the kind of flexibility that keeps loading and unloading robot deployments running continuously across a warehouse dock.

Safety Built Into Every Layer

SLAM-based natural navigation with 360° obstacle detection stops the system automatically when something unexpected appears in its path, while anti-collision switches on both sides of the robotic arm and bottom-mounted sensors halt operation immediately on contact with carton sidewalls. A built-in safety control module calculates the arm's maximum swing range based on vehicle dimensions, preventing contact with truck walls or ceilings before it happens.

From Unload to Storage: The Full Sequence

After the robot unloads a truck, cartons move through a telescopic roller conveyor capable of 180° rotation and a 1:2.5 single-section extension ratio — in this deployment, extending to 24 meters and compressing down to 9.6 meters, allowing deep truck access during operation and compact storage when idle.

From there, a dimension inspection system measures each carton's height and width to determine orientation, followed by six-sided barcode scanning that identifies position and triggers a flipping mechanism to correct posture as needed, with all data uploaded to the central platform. A four-axis robotic arm then palletizes the cartons using a gripper designed to prevent drops, before two electric stacker AGVs and two omnidirectional AGVs — running on laser SLAM navigation and multi-vehicle coordination — complete inbound storage at a combined throughput of 15 pallets per hour.

The result is a dock-to-shelf process that runs without manual handling at any stage — reducing labor need substantially while giving China Tobacco Binzhou a more digitally managed, scalable operation than a partially automated system could offer.
