What is the Difference Between Pick-to-Light and Put-to-Light Systems?

Apr 11,2024
In the realm of warehouse management and order fulfillment, two technologies often mentioned are pick-to-light and put-to-light systems. While both systems are designed to streamline warehouse operations and improve efficiency, they serve slightly different purposes and have distinct functionalities. Let's explore the differences between pick-to-light and put-to-light systems.
Pick-to-Light Systems
Pick-to-light systems are primarily used to guide warehouse workers during the order picking process. Each storage location in the warehouse is equipped with a light module and a display screen. When an order is received, the pick-to-light system directs the worker to the location of the required items by illuminating the corresponding lights and displaying relevant information on the screen.

Key features of pick-to-light systems include:

Order Picking Guidance: Pick-to-light systems provide clear visual cues to warehouse workers, directing them to the exact location of the items needed to fulfill an order.

Hands-free Operation: With pick-to-light systems, workers can focus on picking tasks without the need to refer to paper lists or handheld devices, leading to increased productivity and accuracy.

Order Consolidation: Pick-to-light systems can facilitate order consolidation by guiding workers to pick multiple items for different orders simultaneously, optimizing the picking process.

Put-to-Light Systems
Put-to-light systems, on the other hand, are used primarily for inventory replenishment and stocking tasks within the warehouse. Similar to pick-to-light systems, each storage location is equipped with a light module and a display screen. However, instead of guiding workers to pick items, put-to-light systems direct workers to place items into specific storage locations.

Key features of put-to-light systems include:

Inventory Replenishment: Put-to-light systems guide workers to place items into designated storage locations, ensuring efficient replenishment of inventory levels.

Confirmation of Placement: After placing an item in the designated location, workers confirm the action by pressing a button or scanning a barcode on the display screen, ensuring accuracy in inventory management.

Streamlined Workflow: Put-to-light systems optimize warehouse workflows by providing clear instructions to workers, minimizing search time, and maximizing productivity in stocking tasks.

Key Differences Between Pick-to-Light and Put-to-Light Systems
Primary Function: Pick-to-light systems are primarily used for order picking guidance, while put-to-light systems are used for inventory replenishment and stocking tasks.

Direction of Action: Pick-to-light systems direct workers to pick items from storage locations, whereas put-to-light systems direct workers to place items into storage locations.

Task Focus: Pick-to-light systems focus on facilitating order fulfillment, while put-to-light systems focus on maintaining optimal inventory levels through replenishment tasks.
In summary, while both pick-to-light and put-to-light systems utilize similar technology to improve warehouse operations, they serve different purposes within the order fulfillment process. Understanding the distinctions between these systems is essential for warehouse managers seeking to implement the most suitable technology for their specific operational needs.
