AS/RS Systems, Automated storage and retrieval systems, are computer controlled systems for storing and retrieving products in a warehouse or distribution center. AS/RS Systems require virtually no manual labor and are engineered to be completely automated.
Mini-Load AS/RS systems are smaller systems and typically allow selection of items in totes, trays or cartons. Other terms used to describe a Mini-Load AS/RS system is “case-handling machine” or “tote stacker.”
AS/RS systems are configured with pallet rack laid out with narrow aisles between. Sometimes there is a raised metal rail down the center and a tall mast travels through the aisle along the rail. When the mast reaches the storage location, an AS/RS carriage travels up the mast to the picking spot. An automatic mechanism then reaches into the storage location to retrieve or return the load.
The AS/RS system can be configured many different ways, but typically a smaller system will not use shuttles to pick and retrieve loads. Instead they use extractors that grasp handles on metal trays with robotic arms or vacuums.
Mini-Load systems are usually no higher than forty feet. UNARCO’s time-tested engineering can design a system to meet building codes and withstand the tight tolerances required, no matter the application.
Mini-Load AS/RS are for smaller items such as documents or books or small parts and order fulfillment. UNARCO has installed systems for newspapers and the record storage industry as well as smaller systems in freezers for the food industry. Mini-Load systems are tailored to a customer’s product and specially engineered. Larger product requires a Unit Load AS/RS System.
The benefits of a fixed aisle AS/RS system include the minimized amount of space required and the reduced labor needed to store and retrieve materials. With proper UNARCO engineering, warehouse productivity can be increased substantially. They can also be adapted for use in freezers and other harsh environments that can create hazardous conditions for workers. Because of the computer technology involved AS/RS can create a very accurate form of inventory control.
Automated Storage and Retrieval Systems use computer controlled systems to pick instead of manual labor. Mini-Load systems are for small loads. (illustration reprinted from MMH Magazine)
