Order preparation system
The project goal was to automate the order preparation of all stock keeping units (SKUs) in a warehouse, excluding fresh foods, frozen foods and bulky products. We call such automated solution the ‘Click & Collect’ warehouse.
ProductConsumer goods (groceries, liquids, consumables …)
DimensionsPlastic totes with a specific base of 600 x 400 mm and 3 heights depending on the products to be stocked: 150, 270 and 420 mm.
PerformanceThe installation is sized to handle 8,000 order lines in a 12 hour day.
Operation12 / 24 hour
The solutionThe installation is made up of:
- One static storage of totes in 2 storage racks
- Two high capacity Transtockers for placing and collection of totes
- One, multi-tiered storage unit, ‘front picking’ in the lower part with one side of the storage racks for fast moving products
- One picking operator station which is assisted by ‘Pick & Put-to-Light’
- One conveyor for completed tote transfer to the order consolidation zone
- One re-stock entrance accumulation line for product restocking with a weight and size control
Receipt and storageAfter their receipt, the outer packaging of the products is removed and the goods are put in totes, which are stored in 2 storage racks by high capacity Transtockers.
The order preparationThe preparation is carried out using totes, in 2 steps:
- On the picking station: This station is used for low and medium rotation products. This point is the beginning of the order preparation. The system presents the totes of products to the operator. The operation to pick and place the products into the preparation totes is assisted by ‘pick and put to light’. At this station a dozen orders can be prepared at the same time.
- The dynamic ‘Front picking’: This is a multi-tiered storage system for fast moving products. It is automatically fed by the Transtocker. Trolleys are used by the operator to move along the multi-tiered storage and pick the products. The preparation can be ‘Scanned’ or ‘pick and put to light’ assisted.
