Automatic small parts warehouses (ASPW) are an ideal and efficient solution for storing small-volume goods in containers, cartons or on trays in a space-saving manner. Using intelligent replenishment strategies, they can then be provided dynamically and quickly – for picking, for example.
Storage and retrieval are handled by stacker cranes (SC) or shuttles. ASPW can be used across all sectors and are suitable as spare parts, picking or buffer storage in logistics and distribution centres.
One thing that speaks for automatic small parts warehouses (ASPW) is their high degree of space utilisation: This allows the storage volume to be fully utilised in terms of height. The possibility of multi-depth storage can save even more space. In addition to the increased storage density, the use of suitable, high-performance stacker cranes or shuttles enables high throughputs to be achieved, which in turn decisively influence and maximise the picking performance.
The decisive factors for performance are the short travel distances and access times resulting from the devices’ cycle rate. In addition, multiple load handling devices can be used.
What are the components of an ASPW?
An ASPW essentially consists of a racking system, usually aisle-bound storage and stacker cranes (SC), the automatic control, a pre-zone as well as devices that protect against fire and unauthorised access. According to the warehouse management system’s specifications, the goods are assigned to a SC or shuttle via storage risers and brought from these to the specified storage location. Removal from the warehouse takes place in the same way via retrieval lanes.
For picking provision, there is a choice of using laterally arranged throughput channels for direct removal or connected conveyor technology sections for supplying the pick workstations (goods-to-person) in the pre-zone.
Automatic small parts warehouses are constructed both in the form of a silo and within existing halls. An ASPW is normally selected if, based on previous logistics planning, operation via a stacker crane (SC) or shuttle represents the most economically sensible and permanently practicable solution.
Whereas stacker cranes allow vertical space utilisation up to a height of 30 metres, shuttle systems can be implemented for heights of up to 20 metres (approximate figures, dependent on manufacturer). The achieved benefits are often roughly comparable. However, in direct comparison, shuttle solutions have the edge when it comes to increased redundancy or fail-safety. And shuttles are mainly used for high-performance requirements.
