Abstract

A portable conveyor device, and method of operating and storing the portable conveyor device, the device including a base releasably affixed to a support surface and moveable with respect to the support surface, a first conveyor rotatably attached at a first end to the base by an articulating member, and a second conveyor moveably attached to the base by a vertical conveyor elevation device, wherein the first conveyor being configured to move by the articulating member between a first horizontal position supported on the support surface and a second inclined position and being configured to transport items onto the second conveyor, wherein the second conveyor in a first operating position being configured to receive items from the first conveyor and convey items in both a horizontal direction and a vertical direction.

Claims

1. A portable conveyor device comprising:

a base having means for releasably affixing said base to a support surface and means for moving said base with respect to said support surface;

a first conveyor rotatably attached at a first end to said base by an articulating member;

a second conveyor moveably attached to said base by a vertical conveyor elevation device, and

at least one conveyance item detecting sensor on at least one of said first and said second conveyors that generates a detecting signal when a conveyance item is located on a certain portion of one of said first and second conveyors, said detecting signal is used to control the operation of at least one of said first and second conveyors, said articulating member and said vertical conveyor elevation device,

wherein said first conveyor being configured to move by said articulating member between a first horizontal position supported on said support surface and a second inclined position and being configured to transport items onto said second conveyor,

wherein said second conveyor in a first operating position being configured to receive items from said first conveyor and convey items in both a horizontal direction and a vertical direction.

2. The portable conveyor according to claim 1, wherein said articulating member is rotatably attached to said base.

3. The portable conveyor according to claim 1, wherein said vertical conveyor elevation device elevates said second conveyor in a vertical direction.

4. The portable conveyor according to claim 3, wherein said vertical conveyor elevation device is controlled to elevate said second conveyor from said first operating position to one of a plurality of second maximum height operating positions.

5. The portable conveyor according to claim 1, wherein said articulating member rotates said first conveyor to a storage position that overlays the first conveyor on a top portion of said second conveyor.

6. The portable conveyor according to claim 5, wherein said vertical conveyor elevation device lowers said second conveyor to a storage position below said first operating position.

7. The portable conveyor according to claim 1, wherein said vertical conveyor elevation device positions said second conveyor in said first operating position configured to convey an item in an inclined direction.

8. The portable conveyor according to claim 1, further comprising:

control means for responding to control signals from an external control device that controls the synchronous operation of said first and second conveyors, said articulating member and said vertical conveyor elevation device.

9. The portable conveyor according to claim 1, further comprising:

a UV germicidal irradiation (UVGI) source positioned between a belt of at least one of said first and second conveyors and a protective shield configured to sanitize said belt from micro-organisms.

10. A method of operating a portable conveyor, said portable conveyor including a moveable base, a first conveyor rotatably attached to said base by an articulating member, and a second conveyor movably attached to an upper portion of said base by a vertical conveyor elevation device, said method comprising:

moving said first conveyor by said articulating member into a first horizontal position supported on said support surface, said first conveyor being able to convey items in a horizontal direction;

moving said first conveyor by said articulating member into a second inclined position having a second end of said first conveyor supported on said support surface, said first conveyor being able to convey in an inclined direction to said second conveyor at a first operating position;

elevating said second conveyor in a vertical direction to a second operating position;

sensing one of a presence and an absence of an item on one of said first and second conveyors; and

generating a control signal to control the operation of one of said first and second conveyors, said articulating member and said vertical conveyer elevation device based on said sensing one of a presence and an absence of an item on one of said first and second conveyors.

11. The method according to claim 10, wherein both of said moving said first conveyor by said articulating member further comprises:

rotating said articulating member relative to said base.

12. The method according to claim 10, further comprising:

controlling said portable conveyor to convey items on said second conveyor in both a horizontal and a vertical direction.

13. The method according to claim 10, wherein said second operating position of said second conveyor is configured to be above said first operating position.

14. The method according to claim 10, wherein said elevating said second conveyor further comprises:

controlling said second conveyor to elevate from said first operating position to one of a plurality of second maximum height operating positions.

15. The method according to claim 10, further comprising:

controlling the synchronous operation of said first and second conveyors, said articulating member and said vertical conveyor elevation device by signals transmitted from an external device.

16. A method of operating a portable conveyor, said portable conveyor including a moveable base, a first conveyor rotatably attached to said base by an articulating member, and a second conveyor movably attached to an upper portion of said base by a vertical conveyor elevation device, said method comprising:

lowering said second conveyor from a lowest operating position to a lowered storage position by said vertical conveyor elevation device; and

rotating said first conveyor about a first end by said articulating member, and rotating said articulating member about said base such that said first conveyor overlays a top portion of said second conveyor in said lowered storage position.

17. A portable conveyor device comprising:

a base having means for releasably affixing said base to a support surface and means for moving said base with respect to said support surface;

a first conveyor rotatably attached at a first end to said base by an articulating member; and

a second conveyor moveably attached to said base by a vertical conveyor elevation device,

wherein said first conveyor being configured to move by said articulating member between a first horizontal position supported on said support surface and a second inclined position and being configured to transport items onto said second conveyor,

wherein said second conveyor in a first operating position being configured to receive items from said first conveyor and convey items in both a horizontal direction and a vertical direction, and

wherein said vertical conveyor elevation device lowers said second conveyor to a storage position below said first operating position.

18. A method of operating a portable conveyor, said portable conveyor including a moveable base, a first conveyor rotatably attached to said base by an articulating member, and a second conveyor movably attached to an upper portion of said base by a vertical conveyor elevation device, said method comprising:

moving said first conveyor by said articulating member into a first horizontal position supported on said support surface, said first conveyor being able to convey items in a horizontal direction;

moving said first conveyor by said articulating member into a second inclined position having a second end of said first conveyor supported on said support surface, said first conveyor being able to convey in an inclined direction to said second conveyor at a first operating position;
