Carton flow rack also commonly referred to as gravity flow rack is a great solution for split case picking. Carton flow rack is set up as a FIFO (first in, first out) storage system. These gravity driven systems are loaded from the back side and the product (boxes or cartons) flow to the front of the rack system for pick and packing. Carton flow can either be designed to be implemented with pallet rack systems or to work as standalone units.
Pallets are loaded into the storage lane from the loading aisle and gravity fed, in order, to the discharge aisle. The pallets are first placed onto rollers upon which the pallets easily flow towards the front of the rack system. Once they’ve glided to the front of the system, pallets rest on pallet stops until they’re unloaded. As pallets are removed or unloaded from the system, each of the pallets that were behind them “flow” into the next position via gravity. Pallet speed is controlled by the type of rollers and brakes engineered into the system.
Pallet storage rack is one of the most common pallet storage mediums utilized in a warehouse or distribution center. Pallet racking comes in many forms, from single selective rack to high density pallet storage rack. Many factors go into the design of pallet storage rack, including pallet sizes and weights, accessibility to product requirements, forklift utilization, and many others.
Push-back pallet racks are slightly tilted to utilize the force of gravity, and the pallets sit in a tray positioned along the rails in the rack frame. From the front, loads can be picked and deposited with ease, while the back of the rack remains closed. When a new load is added, it simply pushes existing loads back. This not only decreases pick times, but allows for a high selection of picking faces.
