Industrial Ethernet Auto Storage System for Cold Storage Warehouse Management

１．Product Overview

This auto storage system is designed for cold storage warehouse management where pallet conveying, transfer, lifting, storage, and retrieval need to be coordinated under low-temperature operating conditions. It is suitable for refrigerated warehouses and cold chain logistics projects that require automated pallet movement between inbound stations, outbound stations, buffer sections, transfer points, and high-bay storage areas.

Based on the provided configuration, the system can be built with chain conveyors, roller conveyors, lift transfer units, rack and pinion lifts, and pallet stacker cranes. The pallet conveying section supports 500 / 1000 / 1200 / 2000 kg load classes and standard conveying speeds of 12 / 14 / 16 m/min. The conveyor operating temperature range is -25℃~5℃ for low-temperature applications. The rack and pinion lift provides ±2 mm positioning accuracy, and the pallet stacker crane supports storage heights up to 24 m with rated loads up to 2000 kg.

For warehouse management and task coordination, the system supports Industrial Ethernet communication with WMS. Addressing can be based on laser positioning or barcode positioning, which makes the system suitable for controlled inbound, outbound, location assignment, and inventory-related storage tasks in cold storage projects.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet transport path between inbound points, buffer areas, process interfaces, storage interfaces, and outbound sections. These conveyor modules support continuous pallet flow in refrigerated environments and can be selected according to pallet weight, line layout, and operating rhythm.

Where pallet direction change is required, the lift transfer unit is used to connect conveyor routes and redirect pallet movement between process sections. Where level-to-level or floor-to-floor transfer is required, the rack and pinion lift provides vertical pallet handling with lift loads of 1000 / 2000 kg and positioning accuracy of ±2 mm. For high-bay pallet storage and retrieval, the pallet stacker crane is used as the aisle storage module, supporting up to 24 m storage height and pallet loads up to 2000 kg.

At the control level, the system communicates with WMS through Industrial Ethernet. Addressing can be configured with laser positioning or barcode positioning according to site conditions and control logic. This allows pallet conveying, transfer, storage assignment, retrieval sequencing, and inventory control to work together within one cold storage warehouse management structure.

３．Specifications

４．Application

This system is suitable for cold storage warehouses that require pallet infeed, pallet outfeed, transfer, buffering, and high-bay storage under refrigerated conditions.

It is commonly used in food cold chain warehouses, refrigerated distribution centers, frozen goods storage, finished goods cold storage, and pallet ASRS projects where warehouse tasks need to be coordinated through WMS.

It is also suitable for automated warehouse projects where pallet movement between conveyors, transfer sections, lift interfaces, and storage aisles needs to be managed as one connected warehouse process.

５．Processing

Pallets enter the system through inbound conveyor lines and move through chain conveyors or roller conveyors to buffer sections, transfer points, or storage interfaces.

Where direction change is needed, the lift transfer unit redirects pallets between conveyor routes. Where vertical transfer is needed, the rack and pinion lift moves pallets between different levels with controlled positioning.

For storage operations, the pallet stacker crane receives pallets from the interface section, stores them in assigned rack locations, and retrieves them when outbound tasks are released. Throughout this process, WMS communicates with the system through Industrial Ethernet to coordinate pallet routing, storage location assignment, inventory updates, and outbound task execution.

６．Advantages

The system supports low-temperature operation from -25℃ to 5℃, which makes it suitable for refrigerated warehouses and cold chain pallet handling projects.

The pallet conveying section supports 500 / 1000 / 1200 / 2000 kg load classes, which allows the system to match different pallet weights and warehouse handling requirements.

Industrial Ethernet communication supports WMS-based task coordination for inbound, outbound, storage assignment, and inventory-related control.

The rack and pinion lift provides ±2 mm positioning accuracy, which is useful for level transfer, equipment docking, and stable pallet handover in multi-level layouts.

The pallet stacker crane supports heights up to 24 m and rated loads up to 2000 kg, which makes the system suitable for high-bay refrigerated pallet storage projects.

Laser positioning or barcode positioning can be selected according to project control logic, which helps adapt the system to different warehouse management architectures.

７．How to Choose

Selection should begin with pallet type, pallet size, and actual pallet weight. This determines whether 500 kg, 1000 kg, 1200 kg, or 2000 kg configuration is appropriate for conveying and storage.

Warehouse temperature is another key condition. For cold storage projects operating at -25℃~5℃, the low-temperature conveyor and transfer configuration should be confirmed together with actual frost condition, moisture level, and operating rhythm.

If the project uses high-bay racks, the required storage height and aisle arrangement should be checked to confirm whether a pallet stacker crane up to 24 m is suitable. If the layout includes level transfer or floor connection, the lift load and ±2 mm positioning requirement of the rack and pinion lift should also be reviewed.

Finally, WMS interface requirements, addressing method, inbound and outbound task logic, and throughput target should be confirmed before the final equipment combination is defined.
