This thesis is devoted to automating the process of parcel distribution in the post office to increase the speed and accuracy of processing in the face of the growing demand of e-commerce. The limitations of the existing manual sorting system were analyzed and an automated solution was developed. The work defines the technical parameters and functions of the system, including the operation of conveyors, accurate data collection and parcel sorting. Structural and functional diagrams are developed, and the selection of components such as scanning devices, sorting machines, conveyors, sensors and PLCs is described. The algorithm and control program for the system were created and tested using the STEP 7 development environment and FactoryIo. The proposed automated system is aimed at significantly increasing productivity and reducing errors in the parcel processing process.
