The separation of goods into single-lot storage objects is necessary for single-lot stock management, facilitated by the registration of lot information via WMS at goods-in. In this way – via stock management at storage object level, systematic channel replenishment, and picking from specific storage objects in manual zones – the location of every delivery in the warehouse can be reliably traced. The lot-tracking chain and compliance with lot-tracking laws are then no problem.
Where goods-to-person and other semi-automatic systems are concerned, the software is an autonomous sub-system which controls not only individual components but also manages all storage locations, inventory and goods-in processes. Lots can therefore be traced at all times, expiry dates taken into account and goods which have been returned treated with priority.
In order for lot-tracking to be implemented at an autopicker, it is necessary either for the separate autopicker channels to be replenished in a controlled process or for a sensor to be integrated in the ejector, allowing a new lot to be detected directly at the autopicker itself.
