Abstract

spiral conveyor system comprising a drum associated with a motor, wherein the drum extends from a drum bottom to a drum top; a conveyor belt traveling helically about the drum from an entrance end of the drum to an exit end of the drum; a rib associated with the drum, wherein the rib extends radially from a surface of the drum; and at least one drive face positioned on the rib; wherein the conveyor belt includes at least one belt surface configured to engage the at least one drive face; wherein the length of the rib extends along the length of the drum from a first end of the rib to a terminus of the rib proximate the entrance end of the drum; and wherein the drum includes a ring that extends between the terminus of the rib and the entrance end of the drum, the ring being configured to engage with the conveyor belt.

Claims (11)

CLAIMS :
1. A spiral conveyor system comprising: a drum associated with a motor, wherein the drum extends from a drum bottom to a drum top; a conveyor belt traveling helically about the drum from an entrance end of the drum to an exit end of the drum; a rib associated with the drum, wherein the rib extends radially from a surface of the drum; and at least one drive face positioned on the rib; wherein the conveyor belt includes at least one belt surface configured to engage the at least one drive face; wherein the length of the rib extends along the length of the drum from a first end of the rib to a terminus of the rib proximate the entrance end of the drum; wherein the drum includes a ring that extends between the terminus of the rib and the entrance end of the drum, the ring being configured to engage with the conveyor belt; and wherein the ring abuts the terminus of the rib.
2. The spiral conveyor system of claim 1, wherein the rib defines a radius of the drum; and wherein the ring has a diameter that is approximately the same as the diameter of the drum defined by the rib at the terminus of the rib.
3. The spiral conveyor system of claim 1, wherein the rib defines a radius of the drum; and wherein the ring has a greater radius than the radius of the drum defined by the rib at the terminus of the rib.
4. The spiral conveyor system of claim 1, wherein the rib has a first height at the terminus; wherein the first height is the maximum height of the rib along the length of the rib; and wherein at least a portion of the rib has a tapered height.
5. The spiral conveyor system of claim 1, wherein the first end of the rib is spaced from the exit end of the drum such that the drum includes a ribless portion at the exit end of the drum.
6. The spiral conveyor system of claim 5, wherein the drum includes a plurality of drive elements defined by a plurality of cage bars.
7. The spiral conveyor system of claim 6, wherein the system includes a plurality of cage bar caps configured to cover the cage bars.
8. The spiral conveyor system of claim 7, wherein an entrance end of at least one cage bar cap of the plurality of cage bar caps is spaced from the entrance end of the drum such that the ring is provided between the entrance end of the drum and the entrance end of the at least one cage bar cap.
9. The spiral conveyor system of claim 6, wherein the system includes a cage bar cap including the rib; and wherein the ring of the drum is a separate component attached to, and overlapping a portion of, the cage bar cap.
10. The spiral conveyor system of claim 6, wherein at least a part of the ribless portion extends between two or more of the drive elements.
11. The spiral conveyor system of claim 7, wherein the ring is a separate component from the cage bar caps.
