... is a process whereby the removal of parts is controlled by light signals. By this method, the error rate compared to a document-guided removal can be significantly reduced. At the same time, the picking speed is increased, since the removal compartments are easily detected even from a greater distance. This means that even low-qualified employees can be meaningfully integrated into a high-quality order picking process.

Variant: Order of component removal is relevant

  • Assembly order is started
  • A light signal indicates which component is needed first from which shelf compartment
  • Different quantities are displayed either in different colors or via a graphical display
  • The component is being picked
  • The removal is confirmed on the shelf compartment via the touch sensor
  • The component will be assembled or packed
  • Meanwhile, the light signal for the next required component lights up on the shelf
  • This one is picked, etc.
  • The order has been processed by confirmation of delivery of the last component

Variant: Order of component removal is irrelevant

  • Assembly order is started
  • Light signals indicate which components are required from which shelf compartments
  • Different quantities are displayed either in different colors or via a graphical display
  • The removal can be done for all components in a single shelf run
  • Confirmation of the removal takes place either via the touch sensors on the shelf or centrally for all components at the assembly or picking station
  • This completes the order


Put-to-Light ... is a process for material supply. Here, light signals show where material is missing or in which compartment the current material has to be stored. In particular, if the materials are marked with a barcode, an error-free and, at the same time, fast material replenishment process can be realized.

  • An order is started by e.g. the barcode of the material to be distributed is scanned
  • At the corresponding target containers, a light signal indicates where this component is to be stored
  • The job is completed by confirming the tray via the touch sensor



... describes a process for system-guided assembly.
At trade fairs, we regularly demonstrate that even the most inexperienced visitors to the stand can properly assemble a vehicle (made of Lego) from the right components without a blueprint. Key to this is the pick-by-light system combined with software we call the "visual assembly plan".
The system stores the parts lists of the various vehicle types as well as a photo of each component with the respective installation situation. By scanning the barcode of the relevant parts list, the removal of the first component is started. At the same time, the photo of the installation situation appears on the monitor.
