Return belt tracking idler for conveyor belt system

摘要

A concave conveyor belt idler system for use on the return run of a conveyor belt system, the idler being configured to maintain alignment of the belt and inherently adjust any misalignment thereof occurring during operation of the system. The concave conveyor belt idler system includes an elongated support member extending transversely of a conveyor belt return run and supporting a plurality of idler roller modules positioned such that the roller modules along the anterior side of the support member define a cave shape for supporting the conveyor belt, with the outer lateral edges at a lower elevation than the central portion of the conveyor belt. In a conveyor belt system the concave conveyor belt idler of the disclosed technology is positioned between two planate idler systems, on the return run, so that the center roller of the concave idler is in or near the plane of the belt as it traverses the planate idler systems, with the remaining rollers of the concave idler positioned below this plane.

主权项

1. An idler roller system for the return run of a conveyor belt system, said idler roller system comprising:
a. an elongated support member having a first side and a second side, and comprising a concave support structure; and b. a plurality of rollers designed and configured to be affixed to the first side of the elongated support member, at the support structure, wherein the rollers are provided as roller modules, each roller module comprising a frame having one or more support shafts, upwardly extending end plates rigidly connected to opposing ends of the support shafts, and a central shaft removably affixed to the end plates and supporting the roller for rotation about its longitudinal axis.
