Abstract

A flat wire conveyor belt system includes a plurality of spaced tractive rods and a plurality of rows of pickets transversely disposed with respect to a direction of travel and interconnecting the plurality of spaced tractive rods, each of the rows of pickets including a plurality of first links and a plurality of second links, the plurality of first links have a first spacing and the plurality of second links have a second spacing, the first spacing being less than the second spacing. The system further includes a sprocket, wherein the plurality of first links are configured to engage the sprocket teeth thereof.

Claims

1. A variable spaced flat wire conveyor belt system comprising:

a plurality of spaced tractive rods;

a plurality of rows of flat wire wickets transversely disposed with respect to a direction of travel and interconnecting said plurality of spaced tractive rods, each said wicket having a uniform thickness dimension throughout a width of the conveyor belt;

each of said row of wickets defining a plurality of first links and a plurality of second links, each of said links having a longitudinal height and a transverse spacing; and

at least one sprocket having a plurality of sprocket teeth, said at least one sprocket comprising inner and outer peripheral edges and a smooth supporting surface extending therebetween, each said peripheral edge having a single row of sprocket teeth therearound;

wherein said plurality of first links have a first height and a first transverse spacing and said plurality of second links have a second height and a second transverse spacing, said first height being substantially equal to said second height and said first spacing being less than said second spacing, and

wherein said conveyor belt includes opposing first and second outer edges and at least three of said plurality of first links are disposed on at least the first and second outer edges of the flat wire conveyor belt, said first links being dimensioned for receiving said single rows of sprocket teeth therewithin.

2. The conveyor belt system of claim 1 wherein said plurality of second links are disposed between said first links on the first and second outer edges so as reduce an overall weight of said conveyor belt and increase airflow.

3. The conveyor belt system of claim 1 wherein said at least one sprocket comprises a single sprocket.

4. The conveyor belt system of claim 1 wherein said at least one sprocket comprises at least two sprockets each defining a single row of sprocket teeth.

5. The conveyor belt system of claim 1 wherein said first plurality of links are also disposed in a middle region of each said wicket.

6. The conveyor belt system of claim 1 wherein said first spacing is defined by a 1×

1 mesh and said second links is defined by a 3×

1 mesh.

7. The conveyor belt system of claim 1 wherein said first spacing is defined by a mesh between ½

×

1 and 1×

1.

8. The conveyor belt system of claim 1 wherein said second spacing is defined by a mesh between 3×

1 and 4×

1.

9. The conveyor belt system of claim 1 wherein each of said row of wickets further comprises a plurality of third links, each of said links having a longitudinal height and a transverse spacing;

and wherein said plurality of third links have a third height and a third transverse spacing, said third height being substantially equal to said first and second heights and said third spacing being greater than said first and second spacings.

10. The conveyor belt system of claim 9 wherein said second links are immediately adjacent to said first links.

11. The conveyor belt system of claim 10 wherein said third links are disposed between adjacent said second links.

12. The conveyor belt system of claim 9 wherein said first plurality of links are also disposed in a middle region of each said wicket, said second links being immediately adjacent to said first links and said third links being disposed between adjacent said second links.
