Small-diameter-roller conveyor

摘要

A small-diameter-roller conveyor converted from a large-diameter-roller conveyor and a method for the conversion. One or more belts are trained around the power-driven rollers of a roller conveyor. A stationary array of smaller-diameter article-supporting rollers is positioned atop the belts. The article-supporting rollers are in frictional contact with the belts. The rotation of the power-driven rollers advances the belts, which rotate the article-supporting rollers and convey articles supported atop the article-supporting rollers.

主权项

1. A small-diameter-roller conveyor comprising:
a roller conveyor including a series of at least three power-driven rollers extending axially across the width of the roller conveyor and supported side by side along the length of the roller conveyor, the power-driven rollers having first diameters; at least one endless belt trained around and driven by the power-driven rollers; a stationary array of article-supporting rollers positioned atop the at least one endless belt with the article-supporting rollers extending axially parallel to the power-driven rollers, wherein the article-supporting rollers are rotated by frictional contact with the at least one endless belt; wherein the number of article-supporting rollers exceeds the number of power-driven rollers; and wherein the article-supporting rollers have second diameters less than the first diameters.
