Abstract

The conveyor (10) comprises a modular conveyor belt (102) that includes at least one mat-top chain (100) having at least one cavity (114) and at least one first roller (104) disposed in the cavity (114) of the mat-top chain (110). The conveyor (100) further includes a longitudinal second roller (106) that operatively couples to the first roller (104) such that the longitudianl second roller (106) and the first roller (104) are rotating as the conveyor belt (102) travels along the longitudinal second roller (106). The method fro making a conveyor (100) may comprise the steps of linking a plurality of mat-top chains (100) together to form a modular conveyor belt (102); disposing a first roller (104) into a cavity (114) of the mat-top chain (110); and placing a longitudinal second roller (106) underneath the conveyor belt such that as the conveyor belt travels along the longitudinal second roller, the first roller operatively couples to the longitudinal second roller causing the second roller and first roller to rotate.

Claims (21)

1. A conveyor comprising:

a conveyor belt including a plurality of cavities, a plurality of first diverting rollers, and a plurality of second diverting rollers, each diverting roller being disposed in a cavity;
at least one first transverse roller having an axis that extends in a direction of travel of the conveyor belt and that can couple to the plurality of first diverting rollers to cause the first diverting rollers to rotate as they travel along the at least one first transverse roller;
at least one second transverse roller having an axis that extends in the direction of travel of the conveyor belt and that can couple to the plurality of second diverting rollers to cause the second diverting rollers to rotate as they travel along the at least one second transverse roller; and wherein each of the plurality of first diverting rollers is oriented at a first angle relative to the direction of travel of the conveyor belt and each of the plurality of second diverting rollers is oriented at a second angle relative to the direction of travel of the conveyor belt.
2. The conveyor as defined in claim 1, wherein the at least one first transverse roller and the at least one second transverse roller are located underneath the conveyor belt, wherein the at least one first transverse roller rotates in a direction transverse to the rotational direction of the first diverting rollers as the conveyor belt travels, and wherein the at least one second transverse roller rotates in a direction transverse to the rotational direction of the second diverting rollers.
3. The conveyor as defined in claim 1, wherein the at least one first transverse roller rotates in a first direction substantially perpendicular to the direction of belt travel when the at least one first transverse roller couples to the plurality of first diverting rollers.
4. The conveyor as defined in claim 3, wherein the at least one second transverse roller rotates in a second direction substantially perpendicular to the direction of belt travel when the at least one second transverse roller couples to the plurality of second diverting rollers.
5. The conveyor as defined in claim 1, wherein the at least one first transverse roller and the at least one second transverse roller are selectively vertically displaceable toward or away from the conveyor belt.
6. The conveyor as defined in claim 5, wherein when the at least one first transverse roller is displaced toward the conveyor belt and engages the plurality of first diverting rollers the at least one first transverse roller rotates the first diverting rollers as the conveyor belt travels, and wherein when the at least one second transverse roller is displaced toward the conveyor belt and engages the plurality of second diverting rollers the at least one second transverse roller rotates the second diverting rollers as the conveyor belt travels.
7. The conveyor as defined in claim 1, wherein the rotation of the at least one first transverse roller causes the first diverting rollers to rotate with reduced slippage.
8. The conveyor as defined in claim 1, wherein the first diverting rollers are aligned in the cavities at a first angle relative to the direction of belt travel enabling the first diverting rollers to convey objects in a first direction transverse to the direction of belt travel.
9. The conveyor as defined in claim 8, wherein the second diverting rollers are aligned in the cavities at a second angle relative to the direction of belt travel enabling the second diverting rollers to convey objects in a second direction transverse to the direction of belt travel.
10. A conveyor comprising:
a first conveyor that travels in a direction of belt travel;
a second conveyor belt that travels in the direction of belt travel;
a plurality of cavities disposed in the first conveyor and the second conveyor;
a plurality of first diverting rollers, each first diverting roller disposed in a cavity in the first conveyor;
a plurality of second diverting rollers, each second diverting roller disposed in a cavity in the second conveyor; and a plurality of transverse rollers having axes that extend along the direction of belt travel, the transverse rollers being adapted to couple to the plurality of first diverting rollers and the plurality of second diverting rollers.
11. The conveyor as defined in claim 10, wherein coupling with the first diverting rollers causes the first diverting rollers to rotate in a first direction transverse to the direction of belt travel.
12. The conveyor as defined in claim 11, wherein the coupling with the second diverting rollers causes the second diverting rollers to rotate in a second direction transverse to the direction of belt travel.
13. The conveyor as defined in claim 10, wherein the plurality of transverse rollers are located underneath the first conveyor belt and the second conveyor belt.
14. The conveyor as defined in claim 10, wherein the plurality of transverse rollers are vertically displaceable toward or away from the first conveyor belt and the second conveyor belt.
15. The conveyor as defined in claim 14, wherein when the plurality of transverse rollers are displaced toward the conveyor belt and engage the plurality of first diverting rollers, the transverse rollers rotate the plurality of first diverting rollers as the first conveyor belt travels.
16. The conveyor as defined in claim 14, wherein when the plurality of transverse rollers are displaced toward the conveyor belt and engage the plurality of second diverting rollers, the transverse rollers rotate the plurality of second diverting rollers as the second conveyor belt travels.
17. A method for conveying objects, the method comprising:
driving a conveyor belt in a first direction;
coupling first diverting rollers disposed in the conveyor belt with a first transverse roller that is free to rotate in a direction that is transverse to the first direction;
coupling second diverting rollers disposed in the conveyor belt with a second transverse roller that is free to rotate in a direction that is transverse to the first direction;
selectively diverting objects from the conveyor belt in a second direction using the first diverting rollers; and selectively diverting objects from the conveyor belt in a third direction using the second diverting rollers.
18. The method as defined in claim 17, wherein coupling first diverting rollers comprises vertically displacing the first transverse roller toward the conveyor belt and engaging the first diverting rollers, and wherein the driving of the conveyor belt produces rotary motion in both the first diverting rollers and the first transverse rollers as a result of the coupling.
19. The method as defined in claim 18, wherein coupling second diverting rollers comprises vertically displacing the second transverse roller toward the conveyor belt and engaging the second diver-ting rollers, and wherein the driving of the conveyor belt produces rotary motion in both the second diverting rollers and the second transverse rollers as a result of the coupling.
20. The method as defined in claim 17, further comprising rotating the first diverting rollers at a first angle that is different from the first direction.
21. The method as defined in claim 20, further comprising rotating the second diverting rollers at a second angle that is different from the first direction and that is different from the first angle.
