Abstract: Despite apparent simplicity of the process of paper cutting, the machines, performing this function, are a very important component of printing industry. The quality of preliminary paper cutting significantly influences the quality of the final printed material. It is especially important when printing color materials on one- or two color printing presses or at final processing of materials on machines with automatic feeders. In this case, each sheet of paper is to get through several different machines or through one printing machine several times. And each time the sheet of paper should be automatically straightened within two adjoining sides. Therefore, to guarantee high quality printing, it is necessary to have sheets of the same size, even 90 degree angles and appropriate surface of edges. Otherwise, one and the same sheet can be straightened differently in the alignment mechanism. The purpose of the work is to create a prototype model of a program controlling device for cutting machines used in printing industry. The article considers the system used for cutting automating on cutting machines and controlling this process on s PC. The authors describe the structure of a driving unit of a cutting machine. To achieve the research purpose, the authors use computer simulation and calculation of the necessary processes, then perform mathematical analysis of the obtained model and design the system. The designed system is tested. In the result, the authors develop and realize a discreet drive control system. The authors experimentally prove that a proportionally-integrally-differentiating regulator can be used to guarantee the necessary preset requirements of paper cutting, based on the developed system, and to ensure accurate back gage setting.
Keywords: sensor, controller, asynchronous motor, driving unit of a machine, software control, cutting machines, split back gage, process automation, dynamic properties, computer simulation
