Input station for belt conveyor
First Claim
1. An improved input station for a belt conveyor of the kind including a continuous closed-loop conveyor belt having a width greater than four feet, the conveyor belt moving in a given direction through an input station in a conveyor run, around a head pulley at a discharge location distant from the input station, and back into the input station in an empty return run around a tail pulley, the improved input station comprising:
- a plurality of N fixed frame members each extending transversely of the width of the conveyor belt;
2N fixed outer stanchions, each pair of outer stanchions being mounted on and projecting upwardly of a fixed frame member beyond the outer edge of the conveyor belt;
2N fixed inner stanchions, each pair of inner stanchions mounted in spaced relation to each other and in spaced relation to a pair of the outer stanchions;
2N medial support members, each medial support member disposed between an outer stanchion and its related inner stanchion;
N horizontal center rolls, each extending between one pair of inner stanchions, the center rolls supporting a central portion of the conveyor belt through the input station;
2N troughing rollers, each troughing roller extending between an inner stanchion and a medial support member, the troughing rollers supporting two inner side portions of the conveyor belt throughout the input station;
2N belt support rails, each belt support rail extending throughout the input station to support an outer side portion of the conveyor belt;
and 2N sets of mounting means, one for each belt support rail, for mounting each belt support rail between the outer stanchions and the medial stanchions.

Abstract
An input station for a wide continuous conveyor belt that moves in a conveyor run through an input station to a discharge location, around a head pulley, through a return run around a tail pulley, and back into the input station. At the input station the belt rides on a plurality of N conventional central support rollers each mounted between two inner stanchions. A plurality of at least 2N elongated, flat, stationary slider rails support each extreme outer edge of the conveyor belt through the input station. There are 2N troughing rolls, one at each end of each central roller, between the slider rails and the central rollers. 2N fixed inner stanchions support each central roller and one end of each of its troughing rollers. 2N fixed medial support members each support one end of a troughing roller. The slider rails are supported by the medial support members and by 2N outer stanchions.
