Systems and methods for vacuum extraction for material sorting applications are provided. In one embodiments, a vacuum object sorting system comprises: a vacuum extraction assembly that includes at least one vacuum extractor device having an inlet and an outlet, wherein the at least one vacuum extractor device is configured to convert a controlled compressed air stream into a channeled vacuum airflow entering the inlet and exiting the outlet; and an object recognition device coupled to sorting control logic and electronics, wherein the controlled compressed air stream is controlled in response to a signal generated by the object recognition device; wherein the at least one vacuum extractor device is configured to capture a target object identified by the sorting control logic and electronics utilizing the channeled vacuum airflow, and further utilizing the channeled vacuum airflow, to pass the target object through the inlet and outlet to a deposit location.

The invention relates to energy saving in vacuum systems by means of a method and a controller enabling to consider the fluctuation in system-pressure of a system by determining a maximum system-pressure S2H and a minimum system-pressure S2h for each working cycle W.sub.C based on a determined target system-pressure p.sub.n.sup.− and a pre-set system-pressure p.sub.0.sup.− for the current working cycle W.sub.Cn (n=1, 2, 3, . . . ). The method is especially adapted to fluctuations in system-pressure level of a vacuum system comprising a vacuum gripper tool.

A vacuum system (10) and method (100) used for creating a dynamically controlled vacuum system (10) for lifting processes (Wc) are disclosed. The compressed air used for an ejector (3) is varied by calculating the required vacuum levels (V.sup.−) during the lifting process (Wc). This reduces the air consumption.

A vacuum cup assembly has a vacuum device with a vacuum passageway and a venturi. A vacuum cup is configured to engage an object. The venturi generates an at least partial vacuum at the vacuum cup when the vacuum cup is engaged with an object. The vacuum cup seals against the object when the venturi device generates the at least partial vacuum. A noise reducing device is at a discharge of the venturi. The noise reducing device has a housing defining a chamber, a plurality of spaced exit openings and a movable cap. Air discharged at the venturi is diverted in the chamber and flows out through the exit openings. The movable cap covers the exit opening to override the vacuum to enable the vacuum cup to be positioned or repositioned on the object.
