Infeed Outfeed Industrial Storage Racking Systems Cold Chain Logistics Storage System

Continuous Pallet Infeed and Outfeed Auto Storage System for Cold Chain Logistics

１．Product Overview

This auto storage system is designed for cold chain logistics projects that require continuous pallet infeed, pallet outfeed, buffering, transfer, lifting, and high-bay storage under refrigerated operating conditions. It is suitable for cold storage warehouses, automated pallet warehouses, and cold chain distribution facilities where pallet movement must remain connected across inbound stations, outbound stations, buffer sections, transfer points, and storage aisles.

Based on the listed 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, with conveying speeds of 12 / 14 / 16 m/min. The low-temperature operating range is -25℃~5℃, which makes the system suitable for refrigerated pallet handling and cold chain warehouse automation.

For vertical transfer and high-bay storage, the rack and pinion lift supports lift loads of 1000 / 2000 kg and positioning accuracy of ±2 mm. The pallet stacker crane supports heights up to 24 m and rated pallet loads up to 2000 kg. The system also supports Industrial Ethernet communication with WMS and can use laser or barcode positioning for addressing and task coordination.

２．Technical Solution

The system uses chain conveyors and roller conveyors as the main pallet transport path between inbound points, buffer areas, process interfaces, transfer sections, and outbound stations. These conveyor modules provide continuous pallet flow and can be configured according to pallet load class, conveying rhythm, and line layout.

Where pallet route change is required, the lift transfer unit is used to connect conveyor directions and move pallets between process sections. Where vertical transfer between different levels is required, the rack and pinion lift provides level-to-level pallet movement with controlled positioning. For high-bay storage and retrieval, the pallet stacker crane is used as the aisle storage module for pallet put-away and outbound retrieval.

At the control level, the system communicates with WMS through Industrial Ethernet. Addressing can be based on laser positioning or barcode positioning, depending on site conditions and warehouse control logic. This allows pallet conveying, transfer, storage, retrieval, and inventory-related task management to work together within one cold chain warehouse automation structure.

３．Specifications

４．Application

This system is suitable for cold chain logistics projects that require continuous pallet infeed and pallet outfeed between receiving areas, storage areas, buffer sections, processing interfaces, and shipping stations.

It is commonly used in cold storage warehouses, food cold chain logistics centers, refrigerated distribution centers, finished goods refrigerated storage, and automated high-bay pallet warehouses.

It is also suitable for pallet ASRS projects where inbound and outbound pallet flow needs to remain connected with storage and retrieval tasks under low-temperature conditions.

５．Processing

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

Where pallet direction change is required, the lift transfer unit redirects pallets between conveyor routes. Where level-to-level transfer is needed, the rack and pinion lift moves pallets vertically 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. WMS coordinates pallet routing, storage assignment, inventory updates, and outbound task execution through Industrial Ethernet communication.

６．Advantages

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

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.

Conveying speeds of 12 / 14 / 16 m/min support continuous pallet flow between inbound, outbound, buffer, and transfer sections.

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

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 layouts.

Industrial Ethernet communication with WMS supports connected control of pallet infeed, pallet outfeed, storage tasks, and inventory-related operations.

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 factor. For cold chain projects operating at -25℃~5℃, the low-temperature conveyor and transfer configuration should be confirmed together with frost condition, moisture level, and operating rhythm.

If the project includes 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 warehouse includes multi-level transfer, 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 required throughput rhythm should be confirmed before the final equipment combination is defined.
