For the automated supply of materials to assembly points and workstations in production halls and intralogistics applications, roller conveyors within eKanban racks are fitted with intelligent sensors. If a sensor registers the removal of a small load carrier (SLC) from its rack shelf, a request for replenishment is automatically triggered in the material flow control system. This in turn triggers an order of new materials, without any need for manual activity – and provision is oriented exclusively to real requirements.
