AS/rS
Automated storage and retrieval systems (AS/RS) are computer- and robot-aided systems that can retrieve items or store them in specific locations. The system is usually comprised of predefined locations where machines can follow established routes to get items. As long as everything is stored in its proper location, these systems help to speed up manufacturing and shipping tasks. Typically, automated storage and retrieval systems are used when high volume loads must be moved rapidly and accurately.
Let’s explore the main types of AS/RS systems, how they work and their advantages and disadvantages. The two primary types of AS/RS include unit-load and mini-load systems. Unit-load AS/RS is used for large loads such as handling full pallets or cases of items. Unit-load AS/RS handle the big jobs that may require moving objects or pallets that weigh a few thousand pounds. A typical unit-load AS/RS uses moveable-aisle cranes or fixed-aisle cranes. Mini-load AS/RS, such as case-handling or tote-stacking systems, are smaller cranes or robots that handle lightweight loads such as trays or cartons. Mini-load AS/RS typically use cranes or shuttles. Types of Automated Storage and Retrieval Systems (AS/RS)
Unit-Load AS/RS
Unit-load systems are designed for handling large and heavy loads such as full pallets or cases of items. They are ideal for applications requiring the movement of heavy or large items, and typically employ moveable-aisle cranes or fixed-aisle cranes. These systems are utilized in environments where large amounts of materials need to be stored and retrieved quickly and accurately, such as in manufacturing and distribution centers.
Mini-Load AS/RS
Mini-load systems are suited for handling smaller items, such as cartons, trays, or totes. These systems use smaller cranes or robotic shuttles and are often used in applications where space conservation and efficient handling of smaller loads are crucial. Mini-load AS/RS are common in environments like parts distribution centers and retail distribution centers where a wide variety of small items need to be retrieved quickly.
How AS/RS Systems Work
AS/RS systems typically consist of high-density racking, an integrated software management system, and automation equipment such as cranes or robotic shuttles. The management software directs the automated equipment to the specific locations in the racking to retrieve or store items based on real-time demand. This automation enables precise and rapid handling of materials which increases efficiency.
Advantages of AS/RS Systems
Increased Efficiency: Provides faster retrieval and storage of items, reducing lead times.
Improved Accuracy: Reduces human error through automation and precise software control.
Better Space Utilization: High-density storage reduces space requirements, optimizing warehouse layout.
Enhanced Safety: Reduces the need for manual handling, lowering the risk of injuries and accidents.
