The diploma thesis presents the operation and software implementation of stations on a line with eleven stations, which automatically assemble curved LCD-displays. I participated in the construction of the line as part of a project at INEA d.o.o. At the beginning, the entire installation and the software and hardware used are described. This is followed by a description of how the individual stations work. My part of the project was the tray feeder, which is described in more detail in the following sections. The program logic on the programmable logic controller and the graphic layout of the screens of the human-machine interface were created in the software environment TIA portal V16. According to the customer's requirements, the program logic is mostly written in a ladder diagram. Everything from production to functionality is represented at the end. Based on the fact that we have put the line into operation and that the customers are satisfied, I can assume that the project has been completed successfully.
