Документ Architecture of hybrid mechatronic dosing and packing module of packaging machine based on qualitative analysis(2023) Gavva, Oleksandr M.; Kryvoplias-Volodina, Liudmyla; Marynin, Andriy; Tokarchuk, Serhii; Blazhenko, Serhii; Volodin, OleksandrA qualitative analysis of the process of packaging liquid products (non-carbonated drinking water) using the example of a hybrid mechatronic dosing and packaging module was performed. The computer model of the mechatronic module is described by the basic operators of the Simulink program, taking into account the differential equations for changing the technological parameters of liquid dosing and the accepted initial and boundary conditions of the process. The modes of operation of the hybrid mechatronic dosing and packaging module are programmed using the driver. The boundary conditions of the process of formation and extrusion of the dose of the product are taken into account. The control system of the module is arranged on the principle of feedback and a sharp change in pressure in the portion receiver (from excess, within 3 bars to rarefaction up to –850 mbar). The analysis of individual stages of the dosing process is described, followed by the elaboration of accepted assumptions. During the tests of the computer model of the hybrid mechatronic dosing and packaging module, the accuracy of repetitions of dose formation was determined within ±0.22 % and 0.9 % of the set value of the dose mass of 50…200 ml. An experimental bench was designed, which could provide an opportunity to check the results obtained from the computer model. The research results would allow using digital control and measuring equipment to check the accuracy of dosing of the product from 50 ml to 200 ml. In the course of computer simulation, the effects of the given parameters of the dosing process on the accuracy of the product dose formation were determined, as well as the laws of the necessary distribution of compressed air pressure were formed to maintain the given productivity. The research results could make it possible to improve the designs of liquid product dosing modules and to determine the input parameters for field studies.Документ Synthesis of precision dosing systems for liquid products based on electropneumatic complexes(2021) Gavva, Oleksandr M.; Kryvoplias-Volodina, Liudmyla; Blazhenko, Serhii; Tokarchuk, Serhii; Derenivska, AnastasiiaThis paper reports the construction of a mathe-matical model for the process of dosing liquid foods (non-carbonated drinking water). The model takes into consideration the differential equations of chang-es in the kinematic parameters of the liquid in a dos-ing device's channels and the corresponding accept-ed initial and boundary conditions of the process. The boundary conditions account for the influence of soft-ware-defined airlift dosing modes using the driver and the geometry of the product pipeline. The current's value measured in mA (with an accuracy of 0.001 mA) relative to the standard scale Imin is Imax=4...20 mA.Individual stages of the dosing process were ana-lytically described, followed by the analysis of sepa-rate stages and accepted assumptions.The accuracy achieved when testing the experi-mental sample of the dispenser, with the repetition of the dose displacement process, ranged between 0.35 % and 0.8 %. The reported results are related to the established dosage weight of 50 ml when changing the initial level of liquid in the tank of the dosing feeder by 10 mm.An experimental bench has been proposed for investigating the functional mechatronic dosing mod-ule under the software-defined modes to form and discharge a dose of the product. The bench operates based on proportional feedback elements (4–20 mA) for step and sinusoidal pressure control laws in the dosing device.The control model with working dosing modes has been substantiated. The control models built are based on proportional elements and feedback.During the physical and mathematical modeling, the influence of individual parameters on the accuracy of the product dose formation was determined; ways to ensure the necessary distribution of compressed air pressure, subject to the specified productivity of the dosing feeder, were defined. The study results make it possible to improve the operation of precision dosing systems for liquid products based on electro-pneumat-ic complexes.Документ Лінійні вагові дозувальні пристрої дискретної дії для сипкої продукції (обґрунтування раціональних параметрів)(2014) Гавва, Олександр Миколайович; Деренівська, Анастасія ВасилівнаЦя стаття присвячена проблемі дозування сипких продуктів, вирішення якої лежить у площині вдосконалення дозувальних пристроїв пакувальних машин.

Today machines with linear weigher are dominated on the market packaging machines for particulate product. Operation of each structure element linear weigher affect the basic characteristics of the packaging machine: dosing accuracy and performance. The authors found a functional relationship between dosing accuracy and performance. Therefore, the search for optimal parameters weight feeders should be carried out in the plane of multiobjective optimization. In this article the authors present the results of studies to determine the rational parameters such as: geometrical parameters of the hopper and the intensity of the outflow channel with its products, the intensity displacement feeder products.Документ Ways to reduce dosing error of granular products in linear weight dosing machines(2013) Gavva, Oleksandr M.; Derenivska, Anastasiia; Kryvoplias-Volodina, LiudmylaIn this article there is the result of laboratory research of linear weight dosing machine, providing permanent product flow through outlet port of hopper and minimizing the dynamic part of granular product dosing error, by rational placing of weighing container.Документ Studyng of the viscous food producnts dosing accuracy by the piston batcher(2012) Gavva, Oleksandr M.; Tokarchuk, SerhiiWere provided the research of plug-forming devices gaps size, technological mistakes, and mounting type of kinematic couples and parts of the actuator, influence on dosing systematic error.Документ Дозатор рідких компонентів(2010) Стадник, Ігор Ярославович; Ковальов, Олександр Володимирович; Шутюк, Віталій Володимирович; Удворгелі, Лариса ІванівнаРозроблено дозатор рідких компонентів, який забезпечує безперебійну роботу тістомісильної машини від початку замішування і до вивантаження тіста.
