ABSTRACT:
A gravity type roller conveyor for conveying articles has a plurality of rollers mounted on an elongated support member which is movingly positioned within a base. The base is made of at least two components from a plurality of interchangeable modular components which can be assembled in a variety of ways to produce a base which fits within given requirements. The cases are releasably secured to a frame to complete the conveyor. The frame has a plurality of mounting holes in order to easily allow the changing in width of the conveyor. The base incorporates one or more skid plates to stop the articles on the conveyor. An elongated hose is positioned between the base and the support member and, when inflated, causes the support members to raise rollers upwardly so that the rollers project above the skid plates. The hose, when at least partially deflated, causes the support member to lower the rollers downwardly so that the rollers are positioned below the skid plate whereby the articles supported by the rollers are lowered into engagement with the braking surfaces. A control device provides pressurized air to the hose in a pulsating manner to cause cyclical raising of the articles.
