Put-to-light is an effective method for sorting large batches to individual customer orders and is often used in e-commerce applications. Typical put-to-light cabinets use lights and displays that guide operators through the sorting process. After scanning the product, a blue light turns on at the station where the item should be put. When a order is complete, the system shows a different colored light, often green. We have improved our put-to-light system by using LED strips instead of the typical display. This offers a number of benefits. The most important advantage is the improvement in providing a clear guidance which reduces the risk of miss-sorts. Each cabinet has monitors and scanners to display tasks and progress. Operators can adjust the monitor to the perfect working height with the extendable arm. These cabinets are also offered as cover frames, offering full put-to-light functionality for existing or movable cabinets.
“Traditional PTL cabinets use a display in combination with a single light indication in a horizontal position. By using LED strips in a vertical position, we maximise the visibility.”

By using LED strips in a vertical position, we maximise the visibility. In addition, we have 10 LEDs per location that we can control separately. This allows us to work with patterns and different colours to guide the operators and opens up a new range of possibilities. We can control the colors and patterns for each specific solution, but standard settings include green, blue, orange and red colour codes to indicate specific tasks or errors.
