Summary
ASRS (Automated Storage and Retrieval Systems) are becoming more and more common in intralogistics. Intralogistics includes optimizing, consolidating, automating and managing the logistical flow of goods within a fulfillment or distribution center.
ASRS shuttles are often used to handle pallets of bulk products in warehouses or stock containers in distribution centers with multiple storage levels.
The definition of an automated storage and retrieval system is an automated or semi-automatic system specifically designed for the storage and retrieval of materials, and is a storage process that does not require human intervention in the picking process.
Designers and manufacturers of ASRS shuttles are challenged to move materials quickly, accurately, and efficiently without damaging the cargo being transported .
Automated storage and retrieval systems (ASRS) are used in warehousing and manufacturing. Operators of distribution centers are attracted by the advantages of automated storage and retrieval systems.
01 The implementation of ASRS provides many benefits to users
Store more material in less space
Ability to store in multilayer arrangement
Automatically pick orders
Inventory management
02 ASRS system
ASRS systems are usually multi-level installations. In this article, we will only refer to ASRS on fixed orbit.
Shuttles typically run on rails to move along aisles and ranks. In the picture shown here, one ASRS shuttle sits on top of another like a carriage. The main shuttle moves the goods along the aisle, and the auxiliary shuttle or platoon robot moves the material into a row to the left and right of the aisle.
Each shuttle has a lift mechanism that lifts the pallet. To store and retrieve materials on multiple floors, a piece of equipment called a vertical crane is used. The picture below shows a system that uses a vertical crane to lift pallets or pallets to the proper racking height. Such cranes usually move on two axes. One axis is height and the other axis is positioning along the track on the floor.
Automated storage and retrieval systems have both advantages and disadvantages for operators. The advantage should be fairly obvious, as less manpower and space is required to handle the same amount of material throughout the process . However, the downside is that without a very organized process, the ASRS system may not be as effective . Each of these systems requires a significant up-front investment, and each system may need to be custom-made.
03 Safety Issues and Efficiency of ASRS System
In high-density warehouses, absolute positioning is a must. Precision is important as the shuttle or crane needs to be placed in the proper rack space. For better use of space, the shelf spaces are very close to each other. Improper positioning, whether vertical or straight, can result in a tip-over situation, which can lead to product loss and create safety concerns.
Designers and manufacturers of ASRS vertical cranes were challenged to efficiently move material quickly, accurately and without damaging the transported goods .
