Increase of production efficiency and production output, improvement of its quality while reducing labor costs, upgrade of the forms of organization and production management are the basic elements of mechanical engineering development. This is ensured by the improvement of the existing and introduction of new types of equipment, technological processes and means of their mechanization and automation, creation of new technological complexes where all these issues are interconnected and comprehensively solved.
Means of transportation ensure the continuity and rhythm of work of all structural units of flow production, starting from warehouse operations, supply of a technological object, and the work process of processing to the output of finished products. In terms of automation, the most time-consuming technological operations are those that are associated with the necessary orientation of products.
The most common and effective means of technological object orienting are vibration feeders with an electromagnetic drive. In these devices, the process of orientation of the object (product) is carried out with vibrational movement both on the path of the bowl and on any part of its movement to the working position. The ease of operation and the perfect design of this type of equipment have provided it with a leading place in automated production.
In addition to automation, vibration technology has been widely used in various technological processes, in particular during separation. The orientation of the mixture components referring to the sieve openings significantly increases the screening efficiency. One of the ways to implement this task is to combine vibration processes with the electrical properties of the mixture components in a high-voltage electric field. Сontinuous mode of vibration transportation of the working mixture and the required electric field strength improve the conditions for the working process of vibration separation.
According to the results of the research, it is found that ensuring the appropriate operating parameters of the technological equipment can significantly intensify the process of sifting the mixture components through the sieve openings and thereby reduce its working area.
Combining the considered effects can be applied not only during the interoperational transportation of products but also in the operation of devices for their group cassette and stacking, storage magazines for automatic orientation and positioning for gripping devices of manipulators and industrial robots, and automatic loading devices for technological equipment. These devices must be widely used in production processes associated with products with small mass-geometric parameters.
