A put wall is a collection of compartments into which products can be places as an intermediate step in order fulfillment. When used for e-commerce order fulfillment, for example, each compartment contains a customer order. For store replenishment, put wall compartments contain orders for particular stores. Put walls often employ one side for putting products into compartments and the other side for packing completed orders.
FastFetch’s put wall technology employs lights on each of the individual put-side compartments to support the light-directed putting tasks. Likewise, lights are optionally used on the pack side to highlight completed orders. To fulfill a collection of orders, the required products are first gathered in bulk and transported to the put wall. The individual items are then scanned which causes one or more lights on compartments in the put wall to display the quantity needed for an individual order.
When all of the products for a given order have been placing into the proper compartments, lights on the pack side of the put wall are activated to indicate that the order is ready to pack. Variations in this strategy can be employed to allow multiple workers to complete putting and packing tasks concurrently at the same put wall.
