Conveyor
Conveyors are disclosed herein. An embodiment of a conveyor includes a bed having a first end and a second end, wherein a belt is slidable on the bed. The belt is in a first portion of its travel when it is located adjacent the bed and the belt is in a second portion of its travel when it is located opposite the bed. A curve is located on the first end of the bed, wherein the belt contacts at least a portion of the curve as the belt transitions between the first portion of travel and the second portion of travel.
1. A conveyor comprising
a bed having a first end and a second end;
a belt that is movable relative to the bed, wherein the belt is in a first portion of its travel when it is located adjacent the bed and wherein the belt is in a second portion of its travel when it is located opposite the bed; and
a first curve located on the first end of the bed, wherein the belt contacts at least a portion of the first curve as the belt transitions between the first portion of travel and the second portion of travel; and
a second curve located on the second end of the bed, wherein the belt contacts at least a portion of the second curve as the belt transitions between the first portion of travel and the second portion of travel;
wherein the belt does not contact a roller.
2. The conveyor of claim 1 , wherein the bed and the first curve form a continuous surface.
3. The conveyor of claim 1 , wherein the first curve extends at least one-hundred eighty degrees.
4. The conveyor of claim 1 , wherein the curve extends less than one-hundred eighty degrees.
5. The conveyor of claim 1 , wherein the curve extends greater than one-hundred eighty degrees.
6. The conveyor of claim 1 , wherein the first curve has an end and wherein the end is smooth.
7. The conveyor of claim 1 and further comprising a chain connected to the belt, wherein the belt is movable by way of a force applied to the chain.
8. The conveyor of claim 7 and further comprising at least one sprocket, wherein the chain contacts the sprocket.
9. The conveyor of claim 7 and further comprising a sprocket located at the first end of the bed wherein the chain contacts the sprocket as the belt transitions between the first travel portion and the second travel portion.
10. The conveyor of claim 7 and further comprising a sprocket located at the second end of the bed wherein the chain contacts the sprocket as the belt transitions between the first travel portion.
11. A conveyor comprising:
a bed having a first end and a second end;
a belt that is movable on the bed, wherein the belt is in a first portion of its travel when it is located adjacent the bed and wherein the belt is in a second portion of its travel when it is located opposite the bed;
a first curve located on the first end of the bed, wherein the belt contacts at least a portion of the first curve as the belt transitions between the first portion of travel and the second portion of travel;
at least one cam follower coupled to the belt;
a drum comprising:
a first end;
a second end;
an exterior surface extending between the first end and the second end; wherein the drum is rotatable about an axis extending between the first end and the second end;
at least one cam located in the exterior surface, the at least one cam spiraling between the first end and the second end, and wherein the at least one cam follower is receivable in the at least one cam.
12. The conveyor of claim 11 , wherein the belt has a chain attached thereto, and wherein the at least one cam follower is connected to the chain.
13. A conveyor comprising
a bed having a first end and a second end wherein the bed forms an arc between the first end and the second end;
a belt, wherein the belt is slidable on the bed, wherein the belt is in a first portion of its travel when it is located adjacent the bed, wherein the belt is in a second portion of its travel when it is located opposite the bed, and wherein the belt does not contact a roller;
a first curve located on the first end of the bed, wherein the belt contacts at least a portion of the first curve when the belt is between the first portion of travel and the second portion of travel; and
a second curve located on the second end of the bed, wherein the belt contacts the second curve when the belt is between the first portion of travel and the second portion of travel.
14. The conveyor of claim 13 , wherein the first curve terminates with an edge and wherein the belt does not contact the edge.
15. The conveyor of claim 13 , wherein the curve has an arc distance of approximately one hundred eighty degrees.
16. The conveyor of claim 13 , wherein the belt does not contact a roller in the transition between the first portion of travel and the second portion of travel.
17. The conveyor of claim 1 , wherein the first curve, the second curve, and the bed form a continuous surface.
18. The conveyor of claim 13 , wherein the first curve, the second curve, and the bed form a continuous surface.
