Automated Storage and Retrieval Systems (often referred to as ASRS or AS/RS) refers to a combination of equipment and controls for automatically depositing and retrieving loads from defined storage locations. Systems of this nature have been used for years in manufacturing and warehouse facilities.  ASRS systems can be used in a range of industries including food and beverage, consumer goods, electronics, and more.  Systems vary from relatively simple, manually controlled order-picking machines operating in small storage buffers of 30 m (100 ft.) tall to systems fully integrated into the manufacturing and distribution process.

Unit Load AS/RS is a type of automatic storage and retrieval system that handles large loads (500 to 1000 lbs. and up) that are often placed on pallets or contained in pallet size plastic, wooden or industrial metal containers. Certain large loads, for example steel coils or paper rolls, may also be handled without a pallet base or container.

Mini-Load AS/RS is a type of automatic storage and retrieval system that handles loads that are typically contained in small containers or totes, with load weights typically falling in the 100 to 500 lb. Range, and occasionally as much as 750 to 1000 lbs.

High Speed Picking is the act of selecting and accumulating items that have been ordered, usually done under a well defined process that takes into account historical order patterns for all items eligible to be ordered.

WMS is a software based execution system used to manage inventory, time, and equipment related to picking and processing customer orders. The Warehouse Management System receives orders from the Order Management System or the Transportation Management System, then relies on rules and priorities established by the user to optimize the space and work within the warehouse.

Unit Load
The AS/RS Unit Load technology designed to handle unitized loads into and out of very high density storage. While sometimes used to replenish picking locations with palletized commodities, the most common application of this equipment is for the buffering of supply chain deliveries, storing and controlling the inventory until it has been released, or is requested out for use in downstream processes. This would include the buffering of palletized finished goods waiting for distribution to the end user.

AS/RS Unit Load Features

• Controls – The Unit Load systems have interfaces to plant level warehouse control systems, but they also have end-of-aisle controls for Human Machine Interface (HMI) These systems offer user-friendly touch screens guiding operators through the process of accessing the system, and instructing the operator as to what action to perform on loads delivered to him at that location. These systems also monitor operations, notify the operator or maintenance operation as to problems or PM procedures that need to be performed, and support the quick diagnosis and recovery from any potential error.
• Narrow, Precise Shuttles (Single or Dual) – Provides fast, accurate load transfers while reducing space requirements.
• Ergonomic Workstations - A variety of ergonomic workstations are available with access at end-of-aisle or the side.
• Easy Maintenance – Designed with modular construction and built-in diagnostics simplify installation and maintenance of the AS/RS Mini Load.
• Full Complement of Safety Devices – The AS/RS Unit load has the best in equipment and operator safety devices. The devices available include: redundant lift carriage chains/cables, freefall brakes, safety fences, automatic load alignment and sizing detection, and more.
• Special Loads – With the AS/RS Unit Load, special loads can be accommodated. This includes long or bulky materials, freezer and hazardous material applications, and very-low-noise environments.

AS/RS Mini Load
The unique compact design of the Mini Load AS/RS allows you to store more material in less space. The most common usage of this class of AS/RS is for small parts storage and management for picking and order fulfillment. Often paired with a hybrid combination of Carousels, flow lanes and static racks or shelves, the mini-load provides the best solution for those SKU’s that represent the mid-range of activity.

In this configuration, pans of parts are stored in the system in random order. Each pan may have multiple SKU’s located loosely in the pan, or in specifically segmented and labeled partitions within the pan. The computer system knows where every part is in the system, and on request, brings the pan containing the needed SKU to the operator picking station.

For maintenance efficiency, AS/RS Mini Load’s drives and components have been carefully placed for easy access and quick repairs making installations simpler and faster.

AS/RS Mini Load Features

• Material for the picking operator is presented at an ergonomically ideal position for operator interface. While picking stations are typically located at the end of an aisle, configurations are possible to present the material along the sides of the system.
• Picking instructions are integrated into the Human/Machine Interface at the picking station, reducing strain and maximizing the time spent picking.
• Variety of Load Handling Methods – Including a single or dual shuttle, frame, robotic arm, or extractor load transfer methods. This flexibility allows you to choose the method that best fits your needs.
• Multiple Speed Options – This AS/RS is available with multiple horizontal and vertical speeds allowing you to pick the machine that matches your requirements; high-speed order picking included.
• Multiple Heights – Allows you to maximize the use of overhead space, from 10’ to 50’ in height.
• Small Footprint – The Mini Load has a footprint as narrow as 7’ and is easily installed close to the factory or warehouse use point.
• Space Efficient – This AS/RS provides easy access to totes, multiple items per tote and likewise permits computerized location tracking for thousands of SKUs.
