What Is a Pick to Light System?

A Pick to Light system is a technology-driven order fulfillment method used in warehouses and distribution centers to enhance accuracy and efficiency in the picking process. It employs a series of light modules installed in shelving units or picking bins, which are controlled by a central computer system. 

The system guides operators to the correct location and quantity of items to be picked by illuminating the corresponding lights, reducing errors and increasing productivity. Here are the six basic features of a Pick to Light system:

1. Visual Guidance: The system uses illuminated lights to direct operators to the exact location of items to be picked. Each light corresponds to a specific SKU or product, ensuring accurate picking.

2. Error Prevention: By eliminating the need for paper-based picking lists or manual data entry, the system minimizes human errors, such as picking the wrong item or incorrect quantity.

3. Real-time Inventory Control: Pick to Light systems are integrated with inventory management software, providing up-to-date information on stock levels and reducing the chances of picking out-of-stock items.

4. Increased Efficiency: The visual guidance and streamlined process of a Pick to Light system enhance picking speed and overall productivity, allowing for faster order fulfillment.

5. Scalability: These systems can be easily expanded or modified to accommodate changing business needs, making them adaptable to growth and fluctuations in order volumes.

6. Data Collection and Analytics: Pick to Light systems collect data on picking performance, allowing for analysis and optimization of workflows, employee productivity, and order accuracy.

Overall, Pick to Light systems offer a reliable and efficient solution for improving order fulfillment operations, leading to enhanced customer satisfaction and reduced costs for businesses.

How Does the Pick to Light System Work?

The Pick to Light system is a technology used in warehouses and distribution centers to improve order-picking efficiency and accuracy. It employs a combination of lights, displays, and sensors to guide workers through the picking process. Here’s a step-by-step breakdown of how the Pick to Light system works:

1. Order information: The system receives order information from the warehouse management system (WMS) or an enterprise resource planning (ERP) system. This data includes details such as the items to be picked, their quantities, and their locations within the warehouse.

2. Display modules: Each picking location is equipped with a display module that consists of a numeric or alphanumeric display and a series of indicator lights. The display module is connected to the central control system.

3. Order assignment: The central control system assigns an order to a specific picking location based on availability and proximity. The display module at that location is activated to indicate that it has been assigned an order.

4. Illuminated indicators: Upon activation, the display module illuminates the lights associated with the specific items in the order. Each item has a corresponding light, and the quantity to be picked is displayed on the module.

5. Picking process: The worker locates the picking location indicated by the illuminated lights. They then confirm the quantity to be picked by pressing a button or triggering a sensor on the display module. This action acknowledges the completion of the picking task for that item.

6. Next picking location: Once the worker confirms the completion of the task, the central control system assigns the next picking location and activates the corresponding display module.

7. Order completion: The worker continues the picking process, moving from one location to another until all items in the order have been picked up and confirmed. The system ensures that all items are accounted for and in the correct quantities.

8. Error prevention: The Pick to Light system helps prevent picking errors by providing clear visual guidance and confirmation at each step. If a mistake is made, such as picking the wrong item or incorrect quantity, the system can detect the error and alert the worker through visual or auditory signals.

Overall, the Pick to Light system streamlines the order-picking process by guiding workers efficiently, reducing errors, and improving productivity in warehouse operations.
