Automated Storage and Retrieval Systems (AS/RS) are computer integrated and controlled systems that are used for storing and retrieving goods from a storage location automatically. The main objective of an AS/RS system is to reduce labor costs and increase the efficiency of a warehouse or distribution center.
There are several types of AS/RS systems, including:
1. Unit Load AS/RS: This system is used to store and retrieve large and heavy items that are loaded onto a pallet or a container. It includes a crane or a stacker that lifts the pallet from the storage location and transports it to the picking area.
2. Mini Load AS/RS: This system is used to store and retrieve small items that are loaded into totes or boxes. It includes a smaller crane or a stacker that retrieves the tote or box from the storage location and transports it to the picking area.
3. Vertical Lift Modules (VLM): VLMs are vertical storage systems that consist of trays that are stored in a vertical column. The trays are accessed by a robotic arm that retrieves the required tray and brings it to the picking area.
AS/RS systems can be fully automated or semi-automated. In fully automated systems, the goods are automatically transported from the storage location to the picking area without any human intervention. In semi-automated systems, an operator is required to operate the system.
The benefits of AS/RS systems include:
1. Increased efficiency: AS/RS systems can store and retrieve goods faster and more accurately than manual systems.
2. Space savings: AS/RS systems can store goods in a more compact manner, which can save valuable floor space.
3. Labor savings: AS/RS systems can reduce the need for manual labor in the warehouse, which can save on labor costs.
4. Improved inventory control: AS/RS systems can provide real-time inventory information, which can help to reduce the risk of stockouts and overstocks.
5. Enhanced safety: AS/RS systems can reduce the risk of accidents and injuries associated with manual material handling.
