Документ The integrated layout decisions for automatic control of packing systems(2017) Volodin, Oleksandr; Kryvoplias-Volodina, LiudmylaOn many industrial objects regulators of pressure are used. Following initial data are necessary for proper selection of a regulator and calculation of throughput: a working environment, entrance and target pressure, expense, temperature of a working environment, accuracy of regulation, a class of tightness, diameter of the pipeline, type of accession, constructional materials, external or internal registration of target pressure, protection against excess of pressure. The decision of this problem is closely connected with the proved choice of types of the process equipment, wide automation of technological processes, introduction of new technical decisions, use of necessary means of the control over realization of problems of complex mechanization of technological operations. In article the analysis of work of the functional module of a vertical multiline automatic packing machine on the basis of a proportional regulator of pressure «CAMOZZI» with realization of a feedback by means of an analog signal of regulator МХ-PRO [1-3] is lead. The drive of the holder for a rolled material has been tested on proportional management of position of the directing rollers used on a technological site of supply and regulation of a tension of a tape of a roll of a packing material at formation of packing. Results on use as the operating module of regulator МХ-PRO for management of a drive of the holder for a roll of a material in view of a course and pressure in a pneumatic system are received. Carried out researches provide the way to raise operational properties of a transportation system of supply of a packing material for technological processes of packing modules at the food enterprises. На многих производственных объектах используются регуляторы давления. Для правильного подбора регулятора и расчета пропускной способности необходимы следующие исходные данные: рабочая среда, входное и выходное давление, расход, температура рабочей среды, точность регулирования, класс герметичности, диаметр трубопровода, тип присоединения, конструкционные материалы, внешняя или внутренняя регистрация выходного давления, защита от превышения давления. Решение этой проблемы тесно связано с обоснованным выбором видов технологического оборудования, широкой автоматизацией технологических процессов, внедрением новых технических решений, использованием необходимых средств контроля для реализации задач комплексной механизации технологических операций. В статье проведен анализ работы функционального модуля вертикального многопоточного упаковочного автомата на базе пропорционального регулятора давления «Камоцци» с реализацией обратной связи с помощью аналогового сигнала регулятора МХ-PRO [1-3]. Привод рулонодержателя был протестирован на пропорциональное управление положением направляющих роликов, используемых на технологическом участке подачи и регулирования натяжения ленты рулона упаковочного материала при формировании упаковки. Получены результаты по использованию в качестве управляющего модуля регулятора МХ-PRO для управления приводом рулонодержателя с учетом хода и давления в пневмосистеме. Проведенные исследования дают возможность повысить эксплуатационные свойства транспортной системы подачи упаковочного материала для технологических процессов упаковочных модулей на пищевых предприятиях.Документ Dynamics of mechatronic function modules drives of flow technological lines in food production(2018) Kryvoplias-Volodina, Liudmyla; Gavva, Oleksandr M.; Volodin, Sergiy; Hnativ, TarasThe tasks were considered, which are related to the working bodies for the artificial food products movement according to the specified movement law and their positioning in the intermediate positions of the kinematic cycle.Materials and methods. The actuators dynamics characteristics and control system of power part of positional electro-pneumatic actuators were researched. The methods of mathematical and computer modeling, and methods of solving ordinary differential equations and partial differential equations and method of correlation analysis were used. Results and discussion. The analytical dependences for determining the kinematic parameters of the artificial product movement with the mechanism of collision, which is based on the pneumatic actuator, are obtained. The dynamical model of the actuator is mathematically tested and the movement law of the collision mechanism, which is approximated to the optimal speed, is obtained. To analyze the loading process of the working link of the positional actuator, the model of a generalized control system is used, which is limited by the one full cycle of operation of the functional mechatronic module of the packing machine. Such a model allows to describe the overload process, both in the case of full and partial filling of the working cycle. This is important when packing products in different geometric shapes of consumer packaging, which is typical of modern packaging machines. The simulation model of the actuator is theoretically substantiated and confirmed, which has a number of advantages, unlike the existing structures of positional drives in packaging machines. Сalculated difference, during mathematical modeling, of the value of the working time of the output stage of the functional mechatronic module for the processing of the kinematic cycle of the operation of the packaging machine was for the various input parameters of the limit to 7%. The results of the mathematical modeling of dynamics for a positional pneumatic actuator, with the condition of changing the cross section of the exhaust hole, gave the opportunity to obtain the kinematic characteristics of the drive. Conclusions. The results of mathematical modeling for positional pneumatic actuators with the condition of changing the section of the exhaust hole allowed to track all the kinematic characteristics of the actuator.
