ABSTRACT:
A gravity conveyor is comprised of freely rotatable rollers which include non-displaceable rollers rotatable about stationary axes, and weight-sensitive rollers which are downwardly displaceable under the weight of heavy articles. The non-displaceable rollers are arranged in groups. Upper portions of the non-displaceable rollers of each group define a profile plane. The profile planes of successive groups are mutually parallel and offset downwardly from one another to form a stepped conveying path. When the weight-sensitive rollers are depressed by heavy articles, they will engage, and be braked by, braking rollers disposed therebeneath. An upper portion of each weight-sensitive roller lies in the profile plane of the immediately upstream group of non-displaceable rollers. The weight-sensitive rollers can be mounted on a lever which, when the weight-sensitive rollers are depressed, causes an upstream brake to engage upstream rollers, thereby reducing back pressure applied by upstream articles against downstream articles.
