ABSTRACT:
This invention discloses an accumulation conveyor of the powered roller type, having a power-driven belt passing through a plurality of independent operating zones arranged in tandem along the length of the conveyor. The belt is held in contact with the driven rollers by resiliently-biased pressure rollers, the pressure rollers exerting at least sufficient pressure to maintain the belt in contact with the driven rollers. In each zone, additional pressure is applied to the pressure rollers to increase or decrease the pressure of the belt against the driven rollers. This pressure is applied by spring-biased roller cams actuated by linkages responsive to load-sensing means in a downstream zone and whereby the kinetic energy generated by the moving load is used to actuate the cams.
