Abstract

An example roller is provided. The example roller can include an outer layer having a cylindrical shape, wherein the outer layer extends between a first end and a second end. 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 corrugated plastic filling, wherein the outer layer is wrapped around the corrugated plastic filling.

First claim

What is claimed is:

1 . A roller, comprising:
an outer layer having a cylindrical shape, wherein the outer layer extends between a first end and a second end; a first bearing disposed at the first end; a second bearing disposed at the second end; and a corrugated plastic filling, wherein the outer layer is wrapped around the corrugated plastic filling, wherein the corrugated plastic filling comprises a plurality of corrugated sheets, wherein each of the plurality of corrugated sheets is disposed between two reinforcement layers, and wherein each of the plurality of corrugated sheets is further disposed between two surface treatment layers.

2 . The roller of claim 1 , wherein the corrugated plastic filling defines a cylindrical shape having a hollow center.

3 . The roller of claim 2 , wherein the roller further comprises a first reinforcement layer positioned between the outer layer and the corrugated plastic filling.

4 . The roller of claim 2 , wherein the roller further comprises a second reinforcement layer positioned between the corrugated plastic filling and the hollow center.

5 . The roller of claim 4 , wherein the roller further comprises an inner layer positioned between the second reinforcement layer and the hollow center.

6 . The roller of claim 5 , wherein at least one of the outer layer or the inner layer comprises a surface treatment layer.

7 . The roller of claim 1 , wherein the plurality of corrugated sheets are stacked such that a space inside the outer layer and between the first bearing and the second bearing is filled.

8 . The roller of claim 1 , wherein each of the plurality of corrugated sheets defines a circular shape.

9 . The roller of claim 1 , wherein each of the plurality of corrugated sheets is stacked in a direction extending between the first bearing and the second bearing.

10 . The roller of claim 1 , wherein the plurality of corrugated sheets are joined together.

11 . The roller of claim 1 , wherein the outer layer comprises plastic.

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

13 . The roller of claim 1 , 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.

14 . 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: an outer layer having a cylindrical shape, wherein the outer layer extends between a first end and a second end; a first bearing disposed at the first end; a second bearing disposed at the second end; and a corrugated plastic filling, wherein the outer layer is wrapped around the corrugated plastic filling, wherein the corrugated plastic filling comprises a plurality of corrugated sheets, wherein each of the plurality of corrugated sheets is disposed between two reinforcement layers, and wherein each of the plurality of corrugated sheets is further disposed between two surface treatment layers.

15 . The roller conveyor system of claim 14 , wherein the corrugated plastic filling defines a cylindrical shape having a hollow center.

16 . The roller conveyor system of claim 14 , wherein each of the one or more rollers further comprises a first reinforcement layer positioned between the outer layer and the corrugated plastic filling.

17 . The roller conveyor system of claim 15 , wherein each of the one or more rollers further comprises a second reinforcement layer positioned between the corrugated plastic filling and the hollow center.
