WMS Integrated Auto Storage System Cold Chain Pallet Automatic Racking System

１．Product Overview

This WMS-integrated auto storage system is designed for cold chain pallet warehouses that require coordinated pallet conveying, transfer, lifting, storage, and retrieval under refrigerated operating conditions. It is suitable for automated warehouse management in cold storage environments where pallets need to move continuously between inbound stations, outbound stations, buffer sections, transfer points, and high-bay storage locations.

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 load classes of 500 / 1000 / 1200 / 2000 kg and conveyor speeds of 12 / 14 / 16 m/min. The low-temperature operating range is -25℃~5℃, which makes the system suitable for refrigerated warehouse automation and cold chain logistics handling.

For vertical transfer and high-bay storage, the rack and pinion lift provides ±2 mm positioning accuracy, while the pallet stacker crane supports heights up to 24 m and pallet loads up to 2000 kg. At the control level, the system supports Industrial Ethernet communication with WMS and can use laser or barcode positioning for addressing and storage task coordination.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet flow path between receiving points, storage interfaces, buffer zones, transfer positions, and shipping sections. These modules support continuous pallet movement in cold warehouse operations and can be configured according to pallet load class, conveying rhythm, and line layout.

Where pallet direction change is required, the lift transfer unit is used to connect conveyor routes. Where vertical transfer between different levels is required, the rack and pinion lift provides stable floor-to-floor or level-to-level pallet movement with a lift load of 1000 / 2000 kg and positioning accuracy of ±2 mm. For high-bay storage and retrieval, the pallet stacker crane works as the aisle storage module for pallet put-away and outbound retrieval.

At the software and control level, the system communicates with WMS through Industrial Ethernet. Addressing can be based on laser positioning or barcode positioning, depending on warehouse control logic and site requirements. This allows pallet movement, storage location assignment, inbound sequencing, and outbound task execution to be coordinated within one warehouse management structure.

３．Specifications

４．Application

This system is suitable for cold chain pallet warehouses that require WMS-based task coordination together with continuous pallet infeed, pallet outfeed, buffering, transfer, and high-bay storage.

It is commonly used in cold storage warehouses, food cold chain logistics centers, refrigerated distribution centers, finished goods cold storage, and low-temperature pallet ASRS projects.

It is also suitable for automated high-bay warehouses where pallet movement between conveyor sections, transfer points, lift interfaces, and storage aisles needs to be managed as one connected warehouse automation process.

５．Processing

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

Where route change is needed, the lift transfer unit redirects the pallet between conveyor sections. Where level change is required, the rack and pinion lift moves the pallet vertically between different warehouse 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 manage pallet destination, storage location assignment, inventory updates, inbound sequencing, and outbound retrieval tasks.

６．Advantages

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

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

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

Industrial Ethernet communication with WMS allows pallet conveying, transfer, storage, retrieval, and inventory task control to be managed within one warehouse system.

Laser or barcode positioning can be selected according to site conditions and 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 load. This determines whether 500 kg, 1000 kg, 1200 kg, or 2000 kg configuration is suitable for conveying and storage.

Warehouse temperature is another key factor. For cold chain warehouses operating at -25℃~5℃, the low-temperature configuration should be confirmed together with frost condition, moisture level, and operating rhythm.

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

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