Automated Storage & Retrieval Systems

An Automated Storage & Retrieval System, or AS/RS, are systems comprised of various computer-controlled systems for automatically placing and retrieving loads from defined storage locations. Automated storage and retrieval systems are typically used in applications where:

• There is a very high volume of loads being moved into and out of storage
• Storage density is important because of space constraints
• No value is added in this process (no processing, only storage and transport)
• Accuracy is critical because of potential expensive damages to the load

Unit-Load AS/RS or Fixed-Aisle (F/A) Storage and Retrieval Systems – These systems are used to store large loads (1,000+ pounds) on pallets.

Mini-Load AS/RS – Operate much the same way as a unit-load AS/RS, but handle lighter loads (> 1,000 pounds). Instead of storing pallets, the machines typically store trays, totes or cartons.

Micro-Load AS/RS –Usually handle loads weighing less than 100 pounds in very small containers, totes or trays.

Vertical Lift Modules (VLMs) – Consist of a column of trays in the front and back of the module with an automatic inserter/extractor in the center that stores and retrieves the required trays. Trays can be stored in fixed positions to improve throughput, dynamically to optimize storage capacity, or as a combination of both.

Horizontal Carousels – Comprised of a series of bins that rotate horizontally around a track, similar to a merry-go-round. Ideal for storing small parts and pieces.

Vertical Carousels – House a series of shelves or carriers that rotate vertically, like a Ferris wheel, to provide high-density storage that is ideal for fast-moving, small items. Often used for tooling components, documents, or raw materials storage, vertical carousels are enclosed on all sides to secure high-value items, such as jewelry and electronics.

• Helps cut expenses by minimizing the amount of unnecessary parts and products in storage
• Allows for more storage space due to high-density storage
• Improves the organization of the warehouse
• Automation helps reduce labor costs
• Increased efficiency: products are often sold together can be grouped together to speed up the process of picking, packing, and shipping to customers
