Abstract

A conveyor belt assembly including a flexible belt body with a plurality of spaced flexible teeth and at least one hardened tooth coupled to the belt body. The flexible belt body and flexible teeth comprise a resilient material. The hardened tooth comprises hardened plastic or metal. The flexible belt body also includes at least one reinforcing member within the belt body. A guide member is coupled to the flexible belt body and the hardened tooth to assist in transporting objects on the conveyor belt assembly. A pivotable clamping device clamps the ends of the belt body together to form a continuous belt. The clamping device clamps the reinforcing member to ensure a strong connection.

Claims (20)

1. A conveyor belt assembly comprising:

a flexible belt body having a first end and a second end, the flexible belt body including at least one reinforcing member; and

a pivotable clamping device coupling the first and second ends of the belt into a continuous belt surface, the pivotal clamping device comprising

a first clamp comprising a first upper portion and a first lower portion clamping the reinforcing member on the first end of the belt body, and a second clamp comprising a second upper portion and a second lower portion clamping the reinforcing member on the second end of the belt body, the first and second lower portions each including one of a raised area and a recess;

wherein the first and second upper portions each include the other of a raised area and a recess that interacts with the one of a raised area and a recess of the first and second lower portions to bend the reinforcing member around a tight radius, facilitating better engagement of the clamping mechanism with the reinforcing member.

2. The conveyor belt assembly of claim 1 , wherein the flexible belt body further includes a plurality of spaced flexible teeth positioned on a toothed side of the flexible belt body.

3. The conveyor belt assembly of claim 1 , wherein the first clamp and the second clamp are pivotally coupled to each other.

4. The conveyor belt assembly of claim 1 , wherein the first and second lower portions include a generally tooth-shaped protrusion.

5. The conveyor belt assembly of claim 1 , wherein the first and second lower portions include a layer of adhesive to capture the reinforcing member on the first and second ends of the belt body.

6. The conveyor belt assembly of claim 1 , wherein the pivotable clamping device further includes a central hinge member.

7. The conveyor belt assembly of claim 1 further comprising a guide member coupled to the pivotable clamping device.

8. A conveyor belt assembly comprising:

a flexible belt body having a first end and a second end;

a pivotable clamping device coupling the first and second ends of the belt into a continuous belt surface; and

a generally tooth-shaped protrusion coupled to the pivotable clamping device, the tooth-shaped protrusion facilitating the travel of the pivotable clamping device around a pulley, wherein the pivotable clamping device comprises a first clamp comprising a first upper portion and a first lower portion clamping the first end of the belt body, and a second clamp comprising a second upper portion and a second lower portion clamping the second end of the belt body.

9. The conveyor belt assembly of claim 8 , wherein the pivotable clamping device further includes a central hinge member, and wherein the tooth-shaped protrusion is coupled to the central hinge member.

10. The conveyor belt assembly of claim 8 , wherein the flexible belt body includes at least one reinforcing member, and wherein the first and second clamps clamp the reinforcing member on the first and second ends of the belt body.

11. The conveyor belt assembly of claim 10 , wherein the first and second lower portions include a raised area that secures the reinforcing member, and wherein the first and second upper portions include a recess that interacts with the raised area to bend the reinforcing member around a tight radius, facilitating better engagement of the clamping mechanism with the reinforcing member.

12. The conveyor belt assembly of claim 11 , wherein the first upper portion and first lower portion include mating ridges, and wherein the second upper portion and second lower portion also include mating ridges, and wherein clamping the reinforcing member between the mating ridges further facilitates better engagement of the clamping mechanism with the reinforcing member.

13. The conveyor belt assembly of claim 1 , wherein the first and second lower portions each include a raised area, and wherein the first and second upper portions each include a recess that interacts with the raised area of the first and second lower portions to bend the reinforcing member around a tight radius.
