Put to Light uses the same technology as pick to light, but reverses the process. Product is PUT to an order by lights rather than picked from a location. Two major types of put systems exist. The first is for environments with fast moving product that is common to many orders. Here, the product is scanned, and then all orders wanting the product are lit up, along with the quantity requested. Another type of put system is known as a "consolidation system". Here, partial order requirements arrive in a vehicle (usually a tote). The tote is scanned, and the system then tells the operator which order has requested those partial requirements. This method is used when some requirements are selected at different times, or just the opposite - when you need speed in getting the order together (known as parallel picking). In a parallel pick environment, all components are picked at the same time by several different pickers, and the components are then brought together by the consolidation system. When all requirements have been consolidated, the system knows this and asks the operator to close out the order.
Put systems can save substantial labor if deployed properly. Note that order consolidation can also be done by AS/RS Systems such as Carousels and can be done by RF Terminals or Voice Terminals as well.
