Determination of power and energy indicators of vacuum generators with energy saving function

Generators with the function of energy saving belong to a new group of designs of vacuum generators, which is just beginning to develop.At the research stage, the complex task of determining the kinematic characteristics of the movement of the device for capturing the device during the movement of the package in space was considered for three typical cases when the vectors of the forces of weight, inertia and resistance of the external environment coincide with the axes of the coordinates of the movement of the package in the vertical plane (lifting operation); movement in the horizontal plane (movement operation) and movement in the OXZ plane are combined in time.Taking into account the elastic properties of the gripping elements, the gripping device with packaging is presented in the form of a two-mass discrete model, which consists of a driving mass in the form of combined mass elements of a vacuum drive with a gripping head and a packing mass.The developed mathematical models for ensuring the movement of the gripping device allow to determine the kinematic parameters of the movement of the package according to the known law of motion of the gripping device.The change in the amount of rarefaction in the elements during the holding of the package and during its movement was studied.The proposed approach to determining the holding power of a package with a vacuum suction cup takes into account the requirements for the operation of vacuum generators with an energy saving function.The results of theoretical studies showed that the most necessary when moving the package is the combination of movements in the vertical and horizontal planes, the value of which is recommended to be taken as the maximum when the generator with the energy saving function is working.The obtained changes in the amount of vacuum depending on the diameter of the suction cup for packaging from different packaging materials.
