Abstract

An example roller is provided. The example roller can include a metal tube extending between a first end and a second end, where the metal tube includes an outer surface and an inner surface. The example roller can include a first bearing disposed at the first end. The example roller can include a second bearing disposed at the second end. The example roller can include a reinforcement filling in contact with the inner surface of the metal tube, wherein the reinforcement filling is made at least partially of a non-metal material.

First claim

What is claimed is:

1 . A roller, comprising:
a metal tube extending between a first end and a second end, wherein the metal tube comprises an outer surface and an inner surface; a first bearing disposed at the first end; a second bearing disposed at the second end; and a reinforcement filling in contact with the inner surface of the metal tube, wherein the reinforcement filling is made at least partially of a non-metal material, wherein the reinforcement filling comprises a plurality of corrugated sheets, and wherein at least a first corrugated sheet of the plurality of corrugated sheets is oriented on a horizontal plane, at least a second corrugated sheet of the plurality of corrugated sheets is oriented on a second plane diagonal to the horizontal plane, and at least a third corrugated sheet of the plurality of corrugated sheets is oriented on a third plane diagonal to the second plane and the horizontal plane.

2 . The roller of claim 1 , wherein the reinforcement filling fills a space inside the metal tube and between the first bearing and the second bearing.

3 . The roller of claim 1 , further comprising a shaft, wherein the shaft extends through the metal tube and between the first bearing and the second bearing.

4 . The roller of claim 3 , wherein the reinforcement filling fills a space inside the metal tube, outside the shaft, and between the first bearing and the second bearing.

5 . The roller of claim 1 , wherein the reinforcement filling comprises a corrugated plastic filling.

6 . The roller of claim 5 , wherein the corrugated plastic filling comprises at least one of a honeycomb reinforcement structure, a bubble reinforcement structure, a rectangular reinforcement structure, or a plate reinforcement structure.

7 . The roller of claim 5 , wherein the corrugated plastic filling comprises the plurality of corrugated sheets.

8 . The roller of claim 6 , wherein each of the plurality of corrugated sheets are stacked in a direction extending between the first bearing and the second bearing.

9 . The roller of claim 7 , wherein each of the plurality of corrugated sheets defines a circular shape.

10 . The roller of claim 6 , wherein each of the plurality of corrugated sheets is disposed between two reinforcement layers.

11 . The roller of claim 9 , wherein each of the plurality of corrugated sheets is further disposed between two surface treatment layers.

12 . The roller of claim 7 , wherein the plurality of corrugated sheets are fused together.

13 . The roller of claim 1 , wherein the reinforcement filling comprises a silicone-based powder.

14 . The roller of claim 1 , further comprising a motor positioned inside the metal tube.

15 . The roller of claim 14 , wherein the reinforcement filling fills a space inside the metal tube, outside the motor, and between the first bearing and the second bearing.

16 . The roller of claim 1 , wherein the metal tube comprises 20 gauge metal.

17 . The roller of claim 1 , wherein at least one of the first bearing or the second bearing comprises at least one of a hex shaft or a circular shaft.

18 . A roller conveyor system, comprising:
one or more conveyor frames; one or more conveyor legs; and one or more rollers, each of the one or more rollers comprising:
a metal tube extending between a first end and a second end, wherein the metal tube comprises an outer surface and an inner surface;
a first bearing disposed at the first end;
a second bearing disposed at the second end; and
a reinforcement filling in contact with the inner surface of the metal tube, wherein the reinforcement filling comprises a silicone-based powder.

19 . The roller conveyor system of claim 18 , wherein the reinforcement filling fills a space inside the metal tube and between the first bearing and the second bearing.

20 . The roller conveyor system of claim 18 , further comprising a shaft, wherein the shaft extends through the metal tube and between the first bearing and the second bearing.
