Abstract
A modular roller conveyor system in combination with a conveyor belt and load impact zone for loading material on the conveyor belt. The modular roller conveyor system includes an elongated support member extending transversely of a direction of conveyance for the conveyor belt, and a plurality of modular roller units located in end-to-end abutting engagement with each other on the support member. Each modular roller unit includes a roller support frame having an elongated base portion and upwardly extending end plates at opposing ends of the base portion supporting a shaft and a rotatable shell in supporting engagement with an underside of the conveyor belt. The base portion includes slots extending in the direction of elongation of the base portion, and the support member includes upwardly extending cooperating structures engaging within the slots whereby each modular roller unit is supported for sliding movement in a direction transverse to the direction of conveyance of the conveyor belt to provide a reduction of forces exerted on each modular roller unit through movement of the roller units in response to material impact loads on the conveyor belt.
