Abstract

A conveyor assembly includes a module which can support a roller between adjacent hinge members to simplify modular conveyor assembly and disassembly. The module includes at least two adjacent first hinge members extending in a direction of conveyor travel and defining a space therebetween. The at least two adjacent first hinge members include coaxial openings for receiving a hinge pin therethrough. A first snap fit extension extending from at least one of the adjacent first hinge members toward the other of the adjacent first hinge members for holding a roller in the space substantially coaxial with the openings in the at least two adjacent first hinge members.

Claims

1. A conveyor belt module for use in a modular conveying assembly, said module comprising:

at least two adjacent first hinge members extending in a direction of conveyor travel and defining a space therebetween, said at least two adjacent first hinge members including coaxial openings for receiving a first hinge pin therethrough;

at least one second hinge member extending in a direction opposite of conveyor travel, said at least one second binge member being offset from said at least two adjacent first hinge members and including an opening for receiving a second binge pin therethrough; and

a first snap fit extension extending from at least one of said adjacent first hinge members toward the other of said adjacent first hinge members for holding a roller in said space substantially coaxial with said openings in said at least two adjacent first hinge members.

2. The conveyor belt module as in claim 1, including a roller having a center hole and a width greater than a distance defined between a distal end of said snap fit extension and said other of said adjacent first hinge member, said roller receiving said snap fit extension in said center hole.

3. The conveyor belt module as in claim 2, in which said roller extends above the module.

4. The conveyor belt module as in claim 2, in which said roller extends below the module.

5. The conveyor belt module as in claim 1, in which said conveyor module includes a top surface defined by a leading edge and a trailing edge joined by side edges, and said first hinge members extends rearwardly from said trailing edge.

6. The conveyor belt module as in claim 1, in which a second snap fit extension extends from the other of said adjacent first hinge members toward said first snap fit extension.

7. The conveyor belt module as in claim 6, including a roller having a center hole and width greater than a distance defined between a distal end of said first snap fit extension and a distal end of said second snap fit extension, said roller receiving at least one of said first and second snap fit extensions in said center hole.

8. The conveyor belt module as in claim 1, in which said first snap fit extension includes a proximal end fixed to said first hinge member and a chamfered distal end.

9. A conveyor assembly comprising a conveyor belt module as claimed in claim 1.

10. A modular conveying assembly comprising:

a first conveyor module having at least two adjacent first hinge members extending in a direction of conveyor travel and defining a space therebetween, said at least two adjacent first hinge members including coaxial openings for receiving a first hinge pin therethrough, at least one second hinge member extending in a direction opposite of conveyor travel, said at least one second hinge member being offset from said at least two adjacent first hinge members and including an opening for receiving a second hinge pin therethrough, a first snap fit extension extending from at least one of said adjacent first hinge members toward the other of said adjacent first hinge members, a roller having a center hole substantially aligned with said coaxial opening and receiving said first snap fit extension;

a second conveyor module having a pair of adjacent second hinge members receiving said first hinge members therebetween, said pair of adjacent second hinge members including coaxial openings for receiving said first hinge pin; and

a first hinge pin extending through said coaxial openings of said first and second hinge members and said center hole.

11. The conveyor assembly as in claim 10, in which said a roller has a width greater than a distance defined between a distal end of said snap fit extension and said other of said adjacent first hinge member, said roller receiving said snap fit extension in said center hole.

12. The conveyor assembly as in claim 10, in which said roller extends above the first conveyor module.

13. The conveyor assembly as in claim 10, in which said roller extends below the first conveyor module.

14. The conveyor assembly as in claim 10, in which said first conveyor module includes a top surface defined by a leading edge and a trailing edge joined by side edges, and second hinge members extend forwardly from said leading edge, and said first hinge members extend rearwardly from said trailing edge.

15. The conveyor assembly as in claim 10, in which a second snap fit extension extends from the other of said adjacent first hinge members toward said first snap fit extension.

16. The conveyor assembly as in claim 15, in which said roller has a width greater than a distance defined between a distal end of said first snap fit extension and a distal end of said second snap fit extension, said roller receiving at least one of said first and second snap fit extensions in said center hole.

17. The conveyor assembly as in claim 10, in which said first snap fit extension includes a proximal end fixed to said first hinge member and a chamfered distal end.
