The work is related to the search for the possibilities of using internal energy resources in transport and technological systems by the example of food packaging lines packed in glass containers. Trends in switching to high-performance lines have led to the need for their equipment with dual-purpose transport systems. Obviously, the first task is to ensure the movement of artificial products in the respective sections between units of technological machines, and the second component of their task - to fulfill the role of storage devices in combination with the need for restructuring mass flows. This combination of tasks has led to the exclusive use of closed circuit circuits with two friction planes in transport systems. Meanwhile, it is known that energy costs in mechanical systems are associated with the need to achieve the specified levels of kinetic energy of the moving masses in order to overcome the forces of harmful and useful resistance. The peculiarity of such transport systems is the constant presence of transients and dynamic components of loads.
The study complements the known dynamic manifestations with new ratios of indicators for the possibility of energy recovery.
In the transportation systems for glass production of foodstuffs, the driving factors in most cases are represented by friction forces. Simultaneously, the closure of kinematic pairs between the products and the supporting moving planes is due to gravity forces, which, in cases where their velocities do not coincide, leads to the formation of an additional friction plane with a corresponding increase in energy costs and dynamic components of the loads.
The uneven velocity of the closed circuit circuits is accompanied by additional relative displacements at certain ratios of kinematic and geometric parameters. An appropriate set of parameters is achievable by eliminating these additional displacements of the product arrays relative to the reference planes and limiting energy costs.
The use of rigid kinematic bonds in parallel systems allows for changes in velocities in counter-phases and provides energy recovery. With stabilized kinematic parameters, compared to single-stream systems, higher loads of drive motors with improved performance are achieved.
