Abstract

A diverter conveyor system for a modular belt. The modular belt has at least two belt modules disposed in rows. At least two rows of spheres are disposed in the belt modules and extend through the top and bottom surfaces of the modules. The rows of spheres may be supported by a single cylindrical roller.

Claims

1. A diverter conveyor system, comprising:

a modular belt comprising a plurality of belt modules disposed in rows and a plurality of pivot rods, each pivot rod connecting adjacent modules, the modules having a top surface and a bottom surface, the modules having an intermediate section, a first plurality of link ends extending from the intermediate section, and a second plurality of link ends extending from the intermediate section in a direction opposite to the first plurality of link ends, the first and second link ends having transverse pivot rod openings and being offset such that the first link ends of a first module are capable of intercalating with the second link ends of an adjacent module such that the transverse pivot rod openings align to receive one of the pivot rods;

a plurality of spheres disposed in the belt modules, the spheres extending through the top and bottom surfaces of the modules, the spheres aligned in a plurality of rows, wherein a sphere from each module aligns with corresponding spheres of the preceding and succeeding modules to form a row extending along the belt in a direction of belt travel;

a plurality of cylindrical rollers having longitudinal axes disposed substantially parallel to the direction of belt travel, at least one cylindrical roller disposed adjacent the bottom surface of the belt module such that the roller is capable of simultaneously engaging at least two rows of spheres.

2. The diverter conveyor system of claim 1, wherein each belt module has a pair of spheres.

3. The diverter conveyor system of claim 1, wherein the cylindrical rollers are driven simultaneously.

4. The diverter conveyor system of claim 1, wherein the cylindrical rollers are synchronously driven.

5. The diverter conveyor system of claim 1, further comprising a drive sprocket and a driven sprocket.

6. The diverter conveyor system of claim 1, wherein each cylindrical roller engages two rows of spheres.

7. The diverter conveyor system of claim 1, wherein the belt modules are disposed in rows constructed in bricklayed fashion.

8. A diverter conveyor system, comprising:

a modular belt comprising a plurality of belt modules disposed in rows and a plurality of pivot rods, each pivot rod connecting adjacent modules, the modules, the modules having a top surface and a bottom surface;

a plurality of spheres disposed in the belt modules, the spheres extending through the top and bottom surfaces of the modules, the spheres aligned in a plurality of rows, wherein a sphere from each module aligns with corresponding spheres of the preceding and succeeding modules to form a row extending along the belt in a direction of belt travel;

a plurality of cylindrical rollers having longitudinal axes disposed substantially parallel to the direction of belt travel, at least one cylindrical roller disposed adjacent the bottom surface of the belt module such that one roller makes contact with at least two rows of spheres.

9. The diverter conveyor system of claim 8, wherein each belt module has a pair of spheres.

10. The diverter conveyor system of claim 8, wherein the cylindrical rollers are driven simultaneously.

11. The diverter conveyor system of claim 8, wherein the cylindrical rollers are synchronously driven.

12. The diverter conveyor system of claim 8, further comprising a drive sprocket and a driven sprocket.

13. The diverter conveyor system of claim 8, wherein each cylindrical roller engages two rows of spheres.

14. The diverter conveyor system of claim 8, wherein the belt modules are disposed in rows constructed in bricklayed fashion.

15. The diverter conveyor system of claim 8, wherein the belt modules have an intermediate section, a first plurality of link ends extending from the intermediate section, and a second plurality of link ends extending from the intermediate section in a direction opposite to the first plurality of link ends.

16. The diverter conveyor system of claim 15, wherein the first and second link ends have transverse pivot rod openings.

17. The diverter conveyor system of claim 16, wherein the first and second link ends are offset such that the first link ends of a first module are capable of intercalating with the second link ends of an adjacent module such that the transverse pivot rod openings of the adjacent modules align.
