Pallet Flow Systems
Interroll Pallet Roller Flow storage systems are installed in many storage applications and distribution centres, including ambient, chilled and cold store environments down to -28°C.
First In - First Out: Principle
In FIFO configuration (First In - First Out), the pallets are loaded in the gravity lanes on the entry side (the highest point). The slope then carries the pallets from the loading point to the retrieval point. When a pallet is unloaded, the next pallet automatically takes its place thereby ensuring that the goods are constantly available.
FIFO stock management guarantees stock rotation as the first pallet to be loaded in a lane is the first pallet available at the picking face on the retrieval side. This management method is particularly efficient for perishable goods.
Last In - First Out: Principle
In LIFO configuration (Last In - First Out), a forklift truck loads and unloads the pallets at the picking face. This is a pushback system. To load a pallet, the forklift truck pushes the pallet at the picking face towards the back of the lane using the pallet to be loaded.
When a pallet is unloaded, the pallet stored behind automatically takes its place, thereby ensuring that the goods are constantly available at the picking face.
