Abstract

A center drive module for use with a carousel conveyor that includes a continuous loop conveyor chain. The drive module includes a drive motor that rotates one or more sprocket wheels that each engage drive lugs formed on the bottom surface the conveyor chain to move the conveyor chain along the support frame. The drive module includes a pair of guide rollers positioned on opposite sides of the sprocket wheel. The guide rollers engage the conveyor chain and rotate upon the movement of the conveyor chain. Each of the guide wheels resists vertical movement of the conveyor chain caused by the rotating sprocket wheels.

Claims (31)

1. A drive module for use with a carousel conveyor including a continuous loop conveyor chain movable along a support frame, comprising:

a drive motor;

at least one sprocket wheel rotatably driven by the drive motor, the sprocket wheel having a series of spaced teeth that engage the conveyor chain to move the conveyor chain along the support frame in a longitudinal direction; and

a pair of guide rollers each positioned on opposite sides of the conveyor chain and on opposite sides of the at least one sprocket wheel and aligned with the at least one sprocket wheel, wherein the pair of guide rollers contact opposite sides of the conveyor chain and rotate when the conveyor chain is moving in the longitudinal direction.

2. The drive module of claim 1 wherein each of the drive rollers engage the conveyor chain and restrict movement of the conveyor chain in a direction perpendicular to the longitudinal direction.

3. The drive module of claim 1 wherein the drive motor and the pair of guide rollers are supported by a pair of mounting brackets that are each mounted to the support frame of the carousel conveyor.

4. The drive module of claim 2 wherein each of the guide rollers includes an outer flange that is received within an alignment slot formed in the conveyor chain.

5. The drive module of claim 4 wherein the outer flange of the guide rollers restricts vertical movement of the conveyor chain.

6. The drive module of claim 1 wherein each of the guide rollers is formed from a wear-resistant material and has a circular outer edge.

7. The drive module of claim 1 wherein each of the guide rollers is rotatably mounted within a mounting block connected to one of the mounting brackets.

8. The drive module of claim 2 wherein the at least one sprocket wheel engages a bottom surface of the conveyor chain.

9. A drive module for use with a carousel conveyor including a continuous loop conveyor chain supported along a support frame that defines a conveyor path, comprising:

a drive motor;

at least one sprocket wheel rotatably driven by the drive motor, the sprocket wheel having a series of spaced teeth that engage the conveyor chain to move the conveyor chain along the conveyor path in a longitudinal direction;

a pair of guide rollers positioned on opposite sides of the conveyor chain and on opposite sides of the at least one sprocket wheel and aligned with the at least one sprocket wheel, wherein each of the guide rollers includes an outer flange that is received within an alignment slot formed in the conveyor chain,

wherein the pair of guide rollers prevents movement of the conveyor chain in a direction perpendicular to the longitudinal direction.

10. The drive module of claim 9 wherein each of the drive rollers engages the conveyor chain and rotates with the longitudinal movement of the conveyor chain.

11. The drive module of claim 10 wherein each of the guide rollers and the drive motor are mounted to a pair of mounting brackets, wherein the mounting brackets are supported along the support frame of the carousel conveyor.

12. The drive module of claim 11 wherein each of the guide rollers are rotatably mounted within a mounting block connected to one of the mounting brackets.

13. The drive module of claim 9 wherein each of the guide rollers is formed from a wear-resistant material and has a circular outer edge.

14. The drive module of claim 9 wherein the at least one sprocket wheel engages a bottom surface of the conveyor chain.

15. A carousel conveyor comprising:

a support frame defining a conveyor path;

a continuous loop conveyor chain movable along the conveyor path, the conveyor chain including a plurality of drive lugs and a pair of alignment slots positioned beneath a top surface of the conveyor chain;

a drive module mounted to the support frame for moving the support chain along the conveyor path, the drive module comprising:

a drive motor;

at least one sprocket wheel rotatably driven by the drive motor, the sprocket wheel having a series of spaced teeth that engage the conveyor chain to move the conveyor chain along the conveyor path in a longitudinal direction;

a pair of guide rollers positioned on opposite sides of the conveyor chain and on opposite sides of the at least one sprocket wheel and aligned with the at least one sprocket wheel, wherein each of the guide rollers includes an outer flange that is received within one of the alignment slots formed in the conveyor chain,

wherein the pair of guide rollers prevents movement of the conveyor chain in a direction perpendicular to the longitudinal direction.

16. The carousel conveyor of claim 15 wherein each of the guide rollers and the drive motor are mounted to a pair of mounting brackets, wherein the mounting brackets are supported along the support frame of the carousel conveyor.

17. The carousel conveyor of claim 15 wherein each of the drive rollers engages the conveyor chain and rotates along with the longitudinal movement of the conveyor chain.
