Документ Synthesis of functional mechatronic modules in a system of packaging machines(2023) Kryvoplias-Volodina, Liudmyla; Tokarchuk, Serhii; Gavva, Oleksandr M.; Zaporozhets, OleksandrThe process of creating a packaging machine for a flow-processing system consists of separate stages: the first - a clear definition of technological functions of the equipment and description of the operating conditions of the packaging machine; the second - the search for principles of construction and organization of the structure of the packaging machine for a particular type of food product; the third - the creation of a pilot technical project, evaluation of the main criteria and parameters to ensure all necessary requirements for operation.Документ Integration of technology in the mechatron module of liquid dosing(2023) Yasychev, Vladyslav; Butyk, Taras; Kryvoplias-Volodina, LiudmylaThe influence of individual parameters on the accuracy of productdose formation was determined during physical and mathematical modeling. We have found ways to ensure the necessary distribution of compressed air pressure, subject to compliance with the specified performance of the dispenser. Research results make it possible to improve the operation of dosing systems for liquid products with high dosing accuracy. The control system is formed on the basis of electro-pneumatic complexes. The control model with dosing operating modes is substantiated. It was established that the consumption of compressed air will depend on the value of the input main pressure P (0.05... 0.4 MPa). The consumption of the product was in the range of 1 ml to 50 ml with a feeder volume of 2.25 l. A mathematical model of the dosing process of liquid products (noncarbonated drinking water, milk, juice) has been developed. Boundary conditions took into account the influence on the formation of the product dose from the programmed current values in mA (with an accuracy of 0.001 mA) in relation to the standard scale Imin, Imax=4..20 mA. An analytical description of individual stages of the dosing process with further analysis of individual stages and accepted assumptions was formed. Tests of the experimental sample of the dispenser showed the accuracy of the repetitions of the dose extrusion (limits ± 0.035% and 0.8%) from the set value of the dose mass up to 50 ml during the change and the initial liquid level in the reservoir of the dispenser feeder.Документ Quantification of a mechatronic pneumatic gripping system for a multi-link robot manipulator(2023) Yemelianov, Dmytro; Shevchenko, Serhii; Kryvoplias-Volodina, LiudmylaThe basis of the work is the tasks related to the synthesis of working bodies for moving artificial food, and the development of a control program for them based on PLC - namely, pneumatic grippers. An urgent task was also to ensure the movement of products processed by a robot manipulator according to the given law of movement. Based on the study of the dynamic characteristics of the drive and the control system of the power part of the position electro-pneumatic drive. Mathematical and computer modeling methods, methods of solving ordinary differential equations and partial differential equations, correlation analysis method are used. Analytical dependencies were obtained for controlling the drive of a robot-manipulator with a pneumatically controlled gripper to determine the kinematic parameters of the product movement during processing. The dynamic model of the pneumatic gripper and its drive was mathematically tested. The law of motion of the final link of the manipulator, close to the optimal speed, was obtained. On the basis of the research calculations and the analysis of the functional mechatronic modules, the energy efficiency of the proposed control scheme of the power part of the positional pneumatic drive was confirmed. The result of the study of the electropneumatic positional drive is presented in the form of an algorithm and a special program for calculating and comparing the kinematic and dynamic parameters of the drive.The technological time of the operation is adjustable and when using the exhaust cross-section of the working chambers of the pneumatic cylinder - 4 mm, the value of the working pressure up to 7 bar, the movement of the rod - up to 200 mm, it has optimal kinematic characteristics of work for a pneumatic gripper. The discrepancy between the value of the time of the working stroke of the output link of the functional mechatronic module calculated during the mathematical modeling after working out the kinematic cycle of the gripper was up to 3% for various input parameters.
