This thesis presents the design and the construction of the machine for quality assurance of packaging closure. The first and second chapter cover the role and importance of the machine in an automated production line. Next, a detailed description of a machine and production process is given. The machine is designed to operate in an automated line with a Siemens programmable logic controller S7-1214.
Chapters three to five explain a basic concept, control program and user interface that serves to manipulate with the machine and informs the user about the machine status. In chapter six and seven, the whole design process and required software tools are described. A standard procedure when designing unique devices, testing and troubleshooting of technical and programming errors are highlighted at the end.
