Аннотация:A mechatronic device for unwinding and broaching rolled materials in discrete mode is studied.To reduce energy consumption, a spring drive with energy recovery is used, in which a pneumatic cylinder is installed to compensate for dissipative losses.Traditionally, such spring drives are used for reciprocating movements of working bodies with a constant mass.A special feature of the operation for unwinding roll materials in discrete mode is the change in the mass of the roll brought to the spring drive.The laws of mass change are established, and an algorithm is proposed that allows programmatic variation of the shutdown time of the pneumatic cylinder to ensure the maximum required speed of the carriage in the middle position.In this case, there is a free run-out of the roll and the packaging material is unwound, so that the tape hangs along the route.Further work cycles are performed in idle mode with minimal energy consumption.The change in mass is controlled by accounting for the number of cycles, and the mass reduction by a specific amount is set by the program.The results of the work are used when developing a mechatronic pneumatic system for the drives of a filling and packaging machine.It is supposed that the results can be used by developers of energy-saving technological equipment.
