Abstract

A conveyor belt module has a textured top surface to prevent adhesion of products thereto. The textured top surface is formed by a pattern of humps. The pattern comprises sets of asymmetric and symmetric humps. The symmetric humps are perpendicular to the asymmetric humps. Openings through the module are formed in between the humps.

First claim

What is claimed is:

1. A conveyor belt, comprising:
a textured top surface having a first set of asymmetric humps, each asymmetric hump characterized by a relatively steep first face and a more gradual second face opposite the first face, and a first set of symmetric humps, wherein each symmetric hump is symmetric about both a lateral plane and a longitudinal plane;
a bottom surface;
a first side edge;
a second side edge;
a first end; and
a second end, the conveyor belt extending longitudinally from the first end to the second end and laterally from the first side edge to the second side edge.

2. The conveyor belt of claim 1 , wherein the asymmetric humps in the first set are spaced laterally apart in a substantially parallel manner and each asymmetric hump extends substantially longitudinally between a first longitudinal location on the top surface and a second longitudinal location on the top surface.

3. The conveyor belt of claim 1 , wherein the symmetric humps are perpendicular to the asymmetric humps.

4. The conveyor belt of claim 1 , further comprising a plurality of openings extending through the conveyor belt from the textured top surface to the bottom surface.

5. The conveyor belt of claim 1 , further comprising a second set of asymmetric humps offset laterally from the first set of asymmetric humps, each asymmetric hump of the second set of asymmetric humps extending substantially longitudinally towards the first set of asymmetric humps from a third longitudinal location on the top surface to a fourth longitudinal location on the top surface.

6. The conveyor belt of claim 5 , wherein the crests of the first set of asymmetric humps overlap the crests of the second set of asymmetric humps.

7. The conveyor belt of claim 1 , wherein at least one symmetric hump extends between ends of two consecutive asymmetric humps.

8. A conveyor belt, comprising:
a textured top surface having a first set of humps and a second set of humps;
a bottom surface;
a first side edge; and
a second side edge, wherein the conveyor belt extends longitudinally from a first end to a second end and laterally from the first side edge to the second side edge and wherein
the humps in the first set are spaced laterally apart and each hump in the first set extends substantially longitudinally from a first longitudinal location on the top surface to a crest and from the crest to a second longitudinal location on the top surface the crest being closer to the first longitudinal location than the second longitudinal location, and
the humps in the second set each extend parallel to and are offset laterally and longitudinally from the humps in the first set.

9. The conveyor belt of claim 8 , wherein each hump in the second set extends substantially longitudinally towards the first set of humps from a third longitudinal location on the top surface to a fourth longitudinal location on the top surface.

10. The conveyor belt of claim 8 , wherein the humps in the first set are asymmetric, each asymmetric hump characterized by a relatively steep first face and a more gradual second face opposite the first face.

11. The conveyor belt of claim 10 , wherein the humps in the second set are asymmetric, each asymmetric hump characterized by a relatively steep first face and a more gradual second face opposite the first face.

12. The conveyor belt of claim 11 , wherein the crests of the first and second sets of humps overlap.

13. The conveyor belt of claim 8 , further comprising a third set of humps arranged in series and extending substantially perpendicular to the first and second sets of humps.

14. The conveyor belt of claim 13 , wherein the humps in the third set are symmetric about both a lateral plane and a longitudinal plane.

15. The conveyor belt of claim 8 , further comprising a plurality of openings extending through the conveyor belt from the top surface to the bottom surface.

16. A conveyor belt module, comprising:
a module body extending longitudinally in the direction of belt travel from a first end to a second end, laterally from a first edge to a second edge and in thickness from a textured top surface to an opposite bottom surface;
a first set of hinge elements spaced apart across first gaps along the first end; and
a second set of hinge elements spaced apart across second gaps along the second end;
wherein the textured top surface has a first set of asymmetric humps, each asymmetric hump characterized by a relatively steep first face and a more gradual second face opposite the first face, and a first set of symmetric humps, wherein each symmetric hump is symmetric about both a lateral plane and a longitudinal plane.

17. The conveyor belt module of claim 16 , wherein the asymmetric humps in the first set extend in a longitudinal direction.

18. The conveyor belt module of claim 17 , wherein the symmetric humps extend substantially perpendicular to the asymmetric humps.

19. The conveyor belt module of claim 16 , further comprising a second set of asymmetric humps parallel to and offset laterally and longitudinally from the first set of asymmetric humps.

20. The conveyor belt module of claim 16 , further comprising a plurality of openings extending through the module body from the top surface to the bottom surface.

21. A conveyor belt module, comprising:
a central spine extending laterally from a first side to a second side, longitudinally from a front end to a rear end and in thickness from a top side to a bottom side;
a front beam parallel to the central spine;
a rear beam parallel to the central spine;
a first set of longitudinal beams extending forward from the central spine and connecting to the front beam;
a second set of longitudinal beams extending rearward from the central spine and connecting to the rear beam;
a first set of laterally spaced apart hinge elements extending from the front beam;
a second set of laterally spaced apart hinge elements extending from the rear beam;
a first set of asymmetric humps formed on top of the first set of longitudinal beams, each asymmetric hump characterized by a relatively steep first face and a more gradual second face opposite the first face; and
a second set of asymmetric humps formed on top of the second set of longitudinal beams, each asymmetric hump characterized by a relatively steep first face and a more gradual second face opposite the first face.

22. The conveyor belt module of claim 21 , wherein the hinge elements in the first set of hinge elements align with longitudinal beams in the first set of longitudinal beams.

23. The conveyor belt module of claim 21 , further comprising a series of symmetric humps extending on top of the front beam, wherein each symmetric hump is symmetric about both a lateral plane and a longitudinal plane.
