Automation of tasks performed by people is one of the natural activities influencing the optimization of production time in Industry 4.0. It helps to eliminate errors and reduce work in conditions dangerous for people. In addition, the implementation of automation allows to shorten production time, save resources, protect the environment and provides a competitive advantage. This publication describes the implementation of the system implemented by us for the integration of two cutting laser stations with one automatic sheet metal storage system and an automatic loading and unloading system to the cutting laser workstations. These activities were previously performed manually by employees. Thanks to the automation of these activities, the preparation and production time was shortened and errors resulting from the need to manually manage the number of sheet metal sheets were eliminated. The system includes a control panel with information on real-time stocks and the production process. The system includes a database informing about the current states of sheet metal sheets available in the automatic warehouse and the number of sheet metal sheets used in the production process. Integration with the ERP system allows the staff to be informed in real time about the production progress, laser cutting time, downtime and the current stock levels of sheet metal in the automatic sheet metal warehouse.
