Abstract

A magnetic conveyor belt module integrates a magnetic element into the body of the module to attract conveyed articles to the body. The magnetic conveyor belt module includes a recess for seating a magnetic element and a retention element for retaining the magnetic element within the recess. A cover encapsulates the magnetic element within the body of the module. A non-magnetic conveyor belt module is connected to the magnetic conveyor belt module to form a conveyor belt. The non-magnetic conveyor belt module has an upper surface that is flush with or above the upper surface of the magnetic conveyor belt module.

First claim

What is claimed is:

1. A conveyor belt, comprising:
a magnetic conveyor belt module comprising
a module body extending in thickness from a first upper surface to a bottom surface, laterally from a first edge to a second edge, and longitudinally from a first end to a second end;
a magnetic insert coupled to the module body, the magnetic insert having a second upper surface that is above the first upper surface of the module body; and

a non-magnetic conveyor belt module connected to the magnetic conveyor belt module, the non-magnetic conveyor belt module having a third upper surface that is non-magnetic and higher than the first upper surface.

2. The conveyor belt of claim 1 , further comprising a plurality of hinge elements for hingedly connecting the magnetic conveyor belt module to the non-magnetic conveyor belt module.

3. The conveyor belt of claim 2 , further comprising a rod retention element for retaining a hinge rod within a passageway formed by alternating hinge elements.

4. The conveyor belt of claim 3 , wherein the magnetic insert comprises a cover housing a magnetic element, the cover engaging the rod retention element to retain the cover on the module body of the magnetic conveyor belt module.

5. The conveyor belt of claim 4 , wherein the rod retention element includes a protrusion and the cover includes a recess for engaging the protrusion.

6. The conveyor belt of claim 1 , wherein the module body of the magnetic conveyor belt module includes a slot formed in the first upper surface and extending from the first edge towards the second edge and the magnetic insert comprises a magnetic element and a cover s inserted in the slot, sandwiching the magnetic element between the module body and the cover, the top of the cover forming the second upper surface.

7. The conveyor belt of claim 6 , wherein the cover includes a recess on an inner surface for engaging a retaining element inserted in a passageway in the module body of the magnetic conveyor belt module below the slot.

8. The conveyor belt of claim 7 , wherein the retaining element includes a detent passing through an opening in the bottom of the slot to retain the cover in the slot.

9. The conveyor belt of claim 8 , wherein the third upper surface is higher than the second upper surface.

10. The conveyor belt of claim 8 , the third upper surface is flush with the second upper surface.

11. The conveyor belt of claim 6 , wherein the cover is ultrasonically welded to the module body.
