Order fulfillment is optimized by conveying order containers only to warehouse zones with picks. The Zone Route system is a discrete order picking system used for distribution operations that need to pick, pack and ship customer orders with more productivity, accuracy and speed. The pre-engineered Zone Route process is based on a configuration that arranges the warehouse into picking zones. Each picking zone supports a specific SKU category, typically by velocity. The layout typically includes 4-16 picking zones. The system can accommodate the transport of inbound inventory for re-stocking.

The Zone Route split case pick system is engineered around a methodology that brings the order container to the worker. Workers remain in an assigned zone; efficiency is gained since workers do not roam the warehouse searching for picks, but instead are focused on picking a segment of the inventory located in a compact geography. In each zone, SKUs are staged on flow rack, shelving and pallets. The zones are slotted based on attributes such as family groups, velocity or cube utilization. The operational method is to route the order container only to the zones where there are picks.
To support the Zone Route System pick method, a conveyor network is provided to control the flow of order cartons into and out of the zones. One worker is stationed in each zone; however additional workers could be added during peak periods. Or, during periods of lower order volume, one worker could traverse multiple zones. The conveyor layout features an accumulation conveyor spine that travels through the entire split case pick module with an exit and a siding for each zone. Each exit point consists of a bar code scanner and a right angle transfer to divert the order container into the pick zone. When the picks are completed, the order container carton flows out on the central conveyor spine. If there are more picks, it moves to another zone(s); if no other picks, it travels directly to packing on the conveyor spine.
The conveyor network is also utilized to replenish inventory to each zone. Inventory for put away is conveyed to the appropriate zone for put away (see example of replenishment using the blue totes).
The “case pick to conveyor” method brings efficiency and accuracy to the order fulfillment process. Low, mid and high velocity stock keeping units are picked from pallet storage racking within the full case pick module. A combination of RF, voice and light directed picking may be used to pick full case SKUs and then place directly onto powered take-away conveyor. Typically, the conveyor network transports the cases to a palletizer (manual or automated). Cases can also be conveyed to a dock door for direct fluid loading onto a truck trailer.
The case pick module with the conveyor network requires constant replenishment of the pick face. The pick face consists of a pallet. Each pick face can be automatically replenished with an automated storage/retrieval sub-system. When the pick face is depleted, the storage/retrieval machine replenishes the pick face with a pallet of the appropriate inventory. Automatic replenishment offers operational value: real time software directed replenishment, high level of inventory accuracy, narrow replenishment aisle, and less warehouse labor for replenishment activity.

Defining an efficient conveyor system is a complex task. Our highly experienced project designers know how to solve even tough challenges. Scott conveyor system installations include:
We offer various designs of vertical transport for unit loads, each suited to customers application. The range includes Scott´s own conveyors and elevators together with proven OEM equipment:
Scott’s range of modular conveyors available for 'light loads’ enables fast start-up and minimises downtime on operating sites. To increase agility in line with industry 4.0, we designed this new range of components around two key themes: Robustness & Flexibility.
You can choose between a classic centralised control system and a decentralised EvoLink control system.
The decentralised control system Evolink has been designed for fast reconfiguration, supporting your growth immediately and at a lower cost. The range also allows for the integration of external components and connections on existing production lines. Each component also has its own group of accessories for dynamic accumulation control.
The EvoLink control architecture is based on four key components:
