Automated small parts storage systems

Automated small parts storage systemis the preferred option when small-volume goods with low to medium weight need to be stored in totes, boxes, or on shelves, and need to be dynamically made available for picking or shipping. The reasons for investing in this technology are usually growing order volumes that need to be processed efficiently, quickly, and without errors, without tying up additional (personnel) resources.

Not all Automated small parts systems are the same. When designing an automated small parts warehouse, several parameters must be considered to ensure that the selected system solution delivers the desired performance without quickly reaching its limits.

One argument in favour of miniload systems is that it can utilise space up to a height of 45 meters very well, and with double- to multiple-deep storage, an even higher storage density is achieved. However, the aisles the machines need to travel take up a significant amount of space. There are also trade-offs in terms of scalability, as additional stacker cranes or miniload cranes can only be added if additional space has been planned for in advance. Therefore, miniloads are primarily recommended when no significant changes are expected in the future in terms of the needed throughput performance.

Shuttle warehouses, on the other hand, have the advantage that several vehicles can perform their duties in parallel in each aisle. It is also possible to switch between levels. With heights of up to 18 meters, the number of shuttles can be increased without issue if necessary. Compared with SRM solutions, users are much more flexible while storage density and performance are roughly comparable. This also applies to implementation, which usually requires a new (hall) building or extensive expansion of the existing space.

Another option is new robotics-based storage and picking systems for small parts handling, which are modular in design, effortlessly keep pace with a company's growth, and can be integrated into smaller urban spaces. While robots operate in tandem with conveyors and picking stations, such an ASRS solution does not require lifts at all. The robots are also designed to place totes at any point around the structure. Picking stations can be placed flexibly, and there are no restrictions on the totes, as they can also be used outside of the automated warehouse.
