1. A compressed-air-operated vacuum generator or vacuum gripper with at least two vacuum units, each vacuum unit comprising: a suction chamber,an intake opening which opens into the suction chamber,an outlet opening which exits from the suction chamber, andat least one drive air opening which opens
1. A compressed-air-operated vacuum generator or vacuum gripper with at least two vacuum units, each vacuum unit comprising: a suction chamber,an intake opening which opens into the suction chamber,an outlet opening which exits from the suction chamber, andat least one drive air opening which opens into the outlet opening, wherein the outlet opening of one of the at least two vacuum units opens into the at least one drive air opening of another of the at least two vacuum units, wherein the at least two vacuum units operate according to at least two different principles for compressed-air-driven generation of a negative pressure. 2. The vacuum generator or vacuum gripper of claim 1, wherein the at least two vacuum units comprise at least one unit selected from a vacuum nozzle, an ejector and a vacuum-generating stage. 3. The vacuum generator or vacuum gripper of claim 1, wherein the at least two vacuum units are connected in series. 4. The vacuum generator or vacuum gripper of claim 1, wherein the at least two vacuum units are arranged in a common housing. 5. The vacuum generator or vacuum gripper of claim 1, wherein the suction chambers of the at least two different vacuum units are separated from each other. 6. The vacuum generator or vacuum gripper of claim 1, wherein the suction chambers of the at least two different vacuum units are connected to one another by at least one movable flap. 7. The vacuum generator or vacuum gripper of claim 6, wherein the at least one movable flap is controllably closed or opened depending on vacuum pressure or volume flow rate, or both. 8. The vacuum generator or vacuum gripper of claim 1, wherein the at least two different principles are selected from the group consisting of Venturi principle, Bernoulli principle, Coanda principle and vortex principle. 9. The vacuum generator or vacuum gripper of claim 1, further comprising a blower system. 10. The vacuum generator or vacuum gripper of claim 1, further comprising a sensor detecting at least one of flow conditions and pressure conditions. 11. The vacuum generator or vacuum gripper of claim 10, wherein the sensor is constructed to detect the at least one of flow conditions and pressure conditions in the suction chamber. 12. The vacuum generator or vacuum gripper of claim 1, wherein the at least two vacuum units vacuum units operate simultaneously. 13. The vacuum generator or vacuum gripper of claim 1, wherein the at least two vacuum units vacuum units operate sequentially.
