Arcuate roller conveyor
A material handling system incorporates one or more arcuate conveying surfaces defined by rollers with a large conveyor radius. The rollers may be tapered rollers, and may be live rollers.
1. A conveyor comprising:
a. a first plurality of rollers defining an arcuate conveying surface, each of the first plurality of rollers comprising a respective inner end and a respective outer end, and a second plurality of the first plurality of rollers comprising inner ends disposed on centers less than 2 inches;
b. a reference arc associated with said arcuate conveying surface, said reference arc having at least one conveyor radius length;
c. said conveyor radius length being greater than 60 inches.
2. The conveyor of claim 1 , wherein said conveyor radius length is at least 96 inches.
3. The conveyor of claim 1 , wherein said conveyor radius length is at least 120 inches.
4. The conveyor of claim 1 , wherein said second plurality comprises outer ends disposed on centers less than 2.375 inches.
5. The conveyor of claim 1 , wherein a second plurality of said first plurality of rollers comprise tapered rollers, the tapered rollers comprising a rate of taper less than 0.030.
6. The conveyor of claim 5 , wherein the tapered rollers comprise a rate of taper of about 0.0129.
7. A conveyor comprising:
a. a first plurality of rollers defining an arcuate conveying surface, a second plurality of the first plurality of roller comprising tapered rollers, the tapered rollers comprising a rate of taper of less than 0.030;
b. a reference arc associated with the arcuate conveying surface, the reference arc having at least one conveyor radius length;
c. the conveyor radius length being greater than 60 inches.
8. The conveyor of claim 7 , wherein the conveyor radius length is at least 96 inches.
9. The conveyor of claim 7 , wherein the conveyor radius length is at least 120 inches.
10. The conveyor of claim 7 , wherein the tapered rollers comprise a rate of taper of about 0.0129.
11. A material handling system comprising a plurality of conveyor sections, at least one conveyor section of the plurality of conveyor sections comprising:
a. a first plurality of rollers defining an arcuate conveying surface, each of the first plurality of rollers comprising a respective inner end and a respective outer end, and a second plurality of the first plurality of rollers comprising inner ends disposed on centers less than 2 inches;
b. a reference arc associated with the arcuate conveying surface, the reference arc having at least one conveyor radius length;
c. the conveyor radius length being greater than 60 inches.
12. The conveyor of claim 11 , wherein the conveyor radius length is at least 96 inches.
13. The conveyor of claim 11 , wherein the conveyor radius length is at least 120 inches.
14. The conveyor of claim 11 , wherein the second plurality comprises outer ends disposed on centers less than 2.375 inches.
15. The conveyor of claim 11 , wherein a second plurality of the first plurality of rollers comprise tapered rollers, the tapered rollers comprising a rate of taper less than 0.030.
16. The conveyor of claim 15 , wherein the tapered rollers comprise a rate of taper of about 0.0129.
