OverviewRenowned for its high-density pallet storage, rapid operation, and adaptability, Daifuku’s Unit Load Automated Storage and Retrieval System (AS/RS) is a versatile automated pallet storage and retrieval solution customizable to specific installation environments and operational requirements, with system heights up to 40 meters.
Features - Fast and Dependable Variety of AS/RS stacker crane types to fit specific load profiles, building dimensions and operating environments; high-quality drives for fast, smooth and reliable performance.
- Advanced Control System Local intelligent network control providing integrated control from front-end equipment to inventory management; real-time monitoring for troubleshooting and management of peripheral load-handling systems.
- Improved Operational Efficiency High-speed stacker cranes automatically store and retrieve loads to reduce cycle times, minimize forklift traffic and optimize energy use through measures such as power regeneration and low electricity consumption.
Load Handling - Closed pallets A pallet with a closed bottom surface such as JIS T11 (1,100 x 1,100) and UK pallet (1,000 x 1,200).
- Euro pallets Standard euro-type skid pallets (common sizes: 800 x 1,200 and 1,000 x 1,200).
- Box pallets Four-legged box pallets commonly used for storing machine parts (handling depends on box foot shape).
- Roll-shaped loads Roll-shaped products such as paper rolls, film sheets, textile rolls and carpets.
- Long objects High-density storage of long pipes, bars and plates up to 6.2 m long.
- In-progress car bodies Handling and buffer storage of painted car bodies in automotive applications.
Special Environments Daifuku offers models tailored to diverse installation environments and item characteristics deployed in specialized environments.
- Fresh and frozen environments Cold-resistant stacker cranes for frozen food handling, applicable from -5°C to -30°C.
- High-temperature environments High-temperature specifications available for processes in the 40°C to 55°C range.
- Cleanroom environments Cleanroom-capable systems meeting ISO Class 6–7 requirements for food, pharmaceutical and precision equipment manufacturers.
- Oily and dusty environments (FMS) Oil-resistant and dust-tolerant specifications for machine-tool surroundings and 24-hour automatic supply/collection of jigs.
Configuration - Single-deep AS/RS Standard configuration: one stacker crane accessing one rack row on each side.
- Double-deep AS/RS Single stacker crane accesses two rack rows on each side for higher density with low to medium throughput.
- Dual crane AS/RS Two stacker cranes operate simultaneously in the same aisle to maximize throughput capacity and resiliency.
- Earthquake countermeasures Additional stoppers, special racking and other measures can be applied to minimize earthquake damage.
Add-ons - Shuttle Cart Electrically powered cart transporting pallets to/from stacker crane load/unload points.
- End-of-aisle conveyors Conveyors to automatically transport pallets to and from load/unload stations; can integrate with transfer vehicles.
- Rack-side conveyor Input/output conveyor placed beside AS/RS to streamline supply to press and processing machines.
- Sorting Transfer Vehicle (STV) Rail-guided vehicle system for transporting and sorting pallets, connecting AS/RS aisles to conveyors.
- Case picking robot Case picking robots for automated palletizing and depalletizing of case goods around the AS/RS.
- Rack-side pick-to-light Using rack sides as picking windows with sliding shutters to ensure operator safety.
Model Systems Explore multiple model system layouts that demonstrate AS/RS movement and integration with peripheral equipment to find a solution matched to throughput and workflow requirements.
