Narrow belt conveyor system
First Claim
1. A belt tensioner for a conveyor comprising two or more endless belts, the belt tensioner comprising:
- an axle member mounted to the conveyor transversely to the belts;
the first bracket assembly for each belt pivotally mounted to the axle member;
a tensioning pulley associated with each belt mounted for rotation with respect to its associated first bracket assembly;
a second bracket assembly pivotally mounted to the axle member;
an actuator connected to the second bracket assembly for pivoting the second bracket assembly about the axle member; and
a lost motion connector connecting each first bracket assembly to the second bracket assembly, whereby, when said second bracket assembly is pivoted by the actuator about the axle member in a direction to apply tension to the belts, each bracket is tensioned individually to approximately the same tension.

Abstract
A narrow belt conveyor system including a plurality of narrow, continuous, spaced-apart belts adapted to receive an accessory such as a sorter, accumulator, diverter, and/or transfer between the belts. The conveyor system includes a pair of side frame members, each with an elongated track that slidingly receives the accessory so that it can be readily moved to selected locations along the length of the conveyor. A belt tensioning mechanism provides for independent tensioning of the conveyor belts. A belt guide track with a low friction insert supports the loaded belt, while the guide rollers engage the edges of the belts along their return runs.
