Abstract

An article-diverting modular conveyor belt employs an article mover on a conveyor belt module for selectively moving a conveyed article towards a side of the module. The article mover may be a transversely-extending endless belt for carrying articles across the belt towards a side of the module. Rollers below the conveyor belt are selectively activated to induce movement of the article mover.

Claims

1. A conveyor belt module, comprising:

a body extending in length from a forward end to a rearward end and in width from a first side edge to a second side edge and in thickness from a top side to an opposite bottom side;

a plurality of hinge elements extending from the forward end and the rearward end;

an endless belt arranged to move transversely relative to the body;

a wheel rotatably mounted in a pocket in adjacent to the first side edge for guiding the endless belt between the top side and the bottom side to form a reversing end of the endless belt; and

an end cap disposed adjacent to the first side edge for enclosing the reversing end of the endless belt.

2. The conveyor belt module of claim 1, wherein the hinge elements have a top surface that is lower than the top side of the body.

3. The conveyor belt module of claim 1, wherein the body includes a channel in the top surface for receiving the endless belt.

4. The conveyor belt module of claim 3, wherein the channel includes a plurality of rollers forming a carryway for the endless belt.

5. The conveyor belt module of claim 1, wherein the endless belt comprises a plurality of hingedly connected molded plastic modules.

6. The conveyor belt module of claim 1, wherein the end cap includes at least one hinge element configured to align with at least one of the hinge elements extending from the body.

7. The conveyor belt module of claim 1, wherein the body includes a plurality of base rollers mounted there to and forming the top side of the body.

8. The conveyor belt module of claim 7, wherein the base rollers include a groove for seating the endless belt.

9. A conveyor belt module, comprising:

a body extending in length from a forward end to a rearward end and in width from a first side edge to a second side edge and in thickness from a top side to an opposite bottom side;

a plurality of hinge elements extending from the forward end and the rearward end;

a plurality of base rollers between the top side and the bottom side and a plurality of upper rollers above the base rollers;

a plurality of longitudinal bridges extending from the first end to the second end above the top surface; and

an endless conveyor belt trained about the upper rollers and arranged to move transversely relative to the body, wherein the longitudinal bridges support the top span of the endless conveyor belt.

10. A conveyor belt module comprising:

an upper surface having a groove;

a transverse endless conveyor belt seated in the groove and flush with the upper surface in an upper span to form a conveying surface that comprises both the upper surface and the upper span of the transverse endless conveyor belt;

a first set of hinge elements extending along a front end of the module; and

a second set of hinge elements extending along a rear end of the module, wherein the groove extends from the first set of hinge elements to the second set of hinge elements, so that the transverse endless belt forms a majority of the conveying surface of the module.

11. The conveyor belt module of claim 10, wherein the upper surface comprises a plurality of rollers.

12. The conveyor belt module of claim 11, further comprising transverse rails for mounting the rollers, the transverse rails receiving the axles of the rollers.

13. The conveyor belt module of claim 10, further comprising a plurality of rollers in the groove forming a carryway for the transverse endless conveyor belt.
