В статті проведено дослідження способу контролю положення плоских деталей взуття, які мають
асиметрію шорсткості поверхонь, за допомогою струменів повітря. Для виконання експериментальних досліджень був
спроектований і виготовлений експериментальний стенд, а також розроблена схема для визначення зусилля
переміщення деталі на позицію контролю. Визначення зусилля переміщення деталі на позицію контролю проводилось
методом електротензометрії. Встановлено параметри камер, а саме – кут нахилу сопел та кількість сопел для
максимального зусилля переміщення
The article considers a study of the method of controlling the position of flat shoe parts that have asymmetry of surface roughness, using air jets. Many natural and artificial materials used in shoe production, in addition to other differences, have different irregularities (different relief), as well as different hairiness on the front and back surfaces, which can be natural, created artificially for decorative or other special purposes during processing. The difference lies in the size of the irregularities and pile, their location on the surfaces, as well as in their elastic properties. This makes it possible to control the position of the flat parts of the shoe according to the properties of the surfaces using methods based on the use of these features. Therefore, the task of creating devices for such control is urgent. The paper considers the principle of operation of devices for controlling the position and orientation of flat parts with asymmetry of surfaces using pneumatics. The article describes the results of the study of the method of control by the properties of surfaces using compressed air, for which the authors received a patent for the invention. To perform experimental research, an experimental stand was designed and manufactured, and a scheme was developed to determine the force of moving the part to the control position. Determination of the force of movement of the part to the control position was carried out by the method of electrotensometry. Experiments were carried out with parts made of different, common shoe materials that have a difference in the irregularities and hairiness of opposite surfaces. When planning the experiments, the following factors were used as factors influencing the force of moving the part to the control position: the angle of inclination of the nozzles and the number of nozzles in each chamber.
