Software for replenishment with put-to-light

Not only picking, assembly and production are supported with the Pick-to-Light software. The reverse procedure with the put-to-light software can also support the replenishment of goods very successfully.

Replenishment of goods in a picking warehouse and the software

Each time the goods are removed from a picking warehouse, the stock is changed and the removal is reported to the warehouse management system. When the minimum stock level in a storage compartment is reached, the goods must be replenished. This process is called replenishment.

Storage location here can be a rack with shelves, a channel in a flow channel or a pallet. There are certainly other types of storage locations, but they do not play a role here first.

The importance of a correct supply of goods

Picking is a chain of different activities. Each step of the chain must be as precise and error-free as possible. Under the term "picking" we often only have the removal and the picker in mind. He is often also called a picker.

However, without the precise and error-free replenishment of goods, picking cannot function correctly. For this reason, its quality is just as important as the picking itself. Of course, the performance of the picking side strongly depends on the performance and timing of the replenishment.

Software for system-side support

Almost no one works here today with a slip of paper and a ballpoint pen. Technically, there are various methods to support the filling of the shelves. One of the most common solutions is a hand-held scanner terminal, which is used to store the goods. The article number is scanned, the storage compartment is searched for and the barcode on the storage compartment is scanned as confirmation.

The other option is to support replenishment with a put-to-light system.

When the employee scans the replenishment item, the software triggers the appropriate LED.

Optionally, the put-to-light compartment display can also be additionally equipped with a sensor. The sensor confirms the activity automatically.
