A material handling device includes a vacuum cup pivotally attached to a receiving collar and pivotable to engage a surface of an object to be picked up by the material handling system. The receiving collar includes a support post and a mounting collar that is movable along the support post. The mounting collar is attachable to a support assembly that is movable to move the device toward and into engagement with the object. The mounting collar may move along the post after the respective cup engages the object and while the cups of other devices of the system are moved further toward and into engagement with the object. The material handling device may include an object sensor at a generally central region of the vacuum cup. The material handling device thus is configured to engage objects having uneven surfaces and having varying surface levels from one object to the next.

The embodiments of the invention in which an exclusive property is claimed are defined as follows: 1. A material handling device for engaging and moving an object, said material handling device being attachable to a support assembly that is configured to movably support said material handling device, said material handling device comprising: a vacuum cup having a perimeter seal for engaging and substantially sealing at an object surface, said vacuum cup being attached to a swivel member; an object sensor positioned at least partially within said vacuum cup and directed generally toward an object engaging end of said vacuum cup, said object sensor being operable to sense one of a thickness of an object at said vacuum cup and a proximity of an object at said vacuum cup; a receiving collar having an aperture for pivotally receiving said swivel member, said swivel member having an outer surface that movably engages an inner surface of said receiving collar to allow multi-axis pivoting of said swivel member relative to said receiving collar; a post fixedly attached to and extending from said receiving collar, said post being generally parallel to and spaced from a generally central axis of said aperture of said receiving collar; a mounting collar slidably attached to said post; a biasing element at least partially along said post, said biasing element biasing said mounting collar along said post and away from said receiving collar; and wherein said mounting collar is configured to attach to the support assembly, whereby movement of the support assembly moves said mounting collar and said post to move said vacuum cup toward and into engagement with an object, further movement of the support assembly after said vacuum cup is engaged with the object imparts movement of said mounting collar along said post and toward said receiving collar, said swivel member of said vacuum cup being pivotable within said receiving collar so that said vacuum cup pivots as said material handling device is moved toward an object having a non-level surface and thereby pivots to engage the object. 2. The material handling device of claim 1, wherein said outer surface of said swivel member has a diameter that is substantially similar to a diameter of said perimeter seal of said vacuum cup. 3. The material handling device of claim 2, wherein said swivel member is at a distance from said perimeter seal that is less than approximately one half of said diameter of said perimeter seal. 4. The material handling device of claim 1, wherein said object sensor is positioned at a generally central region of said vacuum cup. 5. The material handling device of claim 1, wherein said swivel member comprises a partially spherical outer surface that slidably engages a correspondingly formed inner surface of said receiving collar. 6. The material handling device of claim 1, wherein said biasing element is positioned at least partially within said post to bias or urge said mounting collar away from said receiving collar. 7. A material handling device for engaging and moving an object, said material handling device being attachable to a support assembly that is configured to movably support said material handling device, said material handling device comprising: a vacuum cup having a perimeter seal for engaging and substantially sealing at all object surface, said vacuum cup being attached to a swivel member; a receiving collar pivotally receiving said swivel member, said swivel member and said receiving collar engaging one another to allow multi-axis pivoting of said swivel member relative to said receiving collar, said receiving collar having a generally central axis therethrough; a post substantially fixedly attached to said receiving collar and extending from said receiving collar, said post being generally parallel to and spaced from said generally central axis of said receiving collar; and a mounting collar movably attached to said post and movable along said post, said post including a biasing element positioned at least partially along said post, said biasing element biasing said mounting collar away from said receiving collar, said mounting collar being configured to attach to the support assembly, whereby movement of the support assembly moves mounting collar, said post and said receiving collar toward an object to move said vacuum cup toward and into engagement with the object. 8. The material handling device of claim 7, wherein said swivel member comprises a partially spherical outer surface that slidably engages a correspondingly formed inner surface of said receiving collar, said outer surface of said swivel member having a diameter that is substantially similar to a diameter of said perimeter seal of said vacuum cup that engages the object. 9. The material handling device of claim 7, wherein said biasing element is positioned at least partially within said post to bias or urge said mounting collar away from said receiving collar. 10. The material handling device of claim 9, wherein said mounting collar engages said biasing element via an engaging member extending at least partially through said post. 11. The material handling device of claim 7 including an object sensing device positioned at least partially through said vacuum cup. 12. The material handling device of claim 11, wherein said object sensing device comprises a proximity sensor operable to sense the proximity of the object at said vacuum cup. 13. The material handling device of claim 11, wherein said object sensing device comprises a double blank detector operable to sense the thickness of the object at said vacuum cup. 14. The material handling device of claim 11, wherein said object sensing device is positioned at a generally central region of said vacuum cup. 15. The material handling device of claim 7, wherein said vacuum cup and said swivel member are pivotable about at least one generally horizontal axis when said receiving collar is in a generally horizontal orientation. 16. The material handling device of claim 7, wherein said swivel member comprises a partially spherical outer surface that slidably engages a correspondingly formed inner surface of said receiving collar. 17. The material handling device of claim 7, wherein said swivel member is at a distance from said perimeter seal that is less than approximately one half of a diameter of said perimeter seal.
