A conveyor roller includes a roller tube, a motor assembly comprising a motor and a motor shaft and a drive assembly engaged with the motor assembly and the roller tube. The drive assembly includes a drive member, a connector, and a sleeve. The drive member includes at least one first slot that axially extends from a front face of the drive member towards a rear face. The connector includes an axial opening and at least one first projection extending radially outwardly. A sleeve disposed at least partially between the connector and the drive member. The sleeve is configured to engage the at least one first slot of the drive member and the at least one first projection of the connector. A portion of the sleeve extends radially outwardly of the drive member, such that the portion of the sleeve is configured to engage an inner surface of the roller tube.

A conveyor bed including a conveyor frame, a first set of rollers, a second set of rollers, and a pivotable frame is provided. The first set of rollers are coupled to the conveyor frame to transport an article from an upstream location to a downstream location. The pivotable frame pivotably coupled to a side of the of the conveyor frame. The second set of rollers mounted to the pivotable frame, positioned below the first set of rollers. A belt wrapped is around the second set of rollers, and selectively engages and disengages the first set of rollers in response to pivoting the pivotable frame based on predefined criteria.

An energy harvesting brake system may comprise a shaft, a roller cylinder, and a piezoelectric material. The roller cylinder may be configured to rotate relative to the shaft in response to a target moving relative to a platform. The piezoelectric material may be in operable communication with the shaft and the roller cylinder such that relative rotational motion between the shaft and the roller cylinder causes cyclic stress in the piezoelectric material thereby generating electrical energy.

The present invention provides an improved conveyor system that provides for a magnetically driven conveyor system in which a sidewall of the conveyor may have minimal or no perforations therein for connecting rollers or other conveying structures in the conveyor bed to an external driving mechanism. The conveyor system may also provide gapless or nearly gapless roller bed that prevents or reduces the accumulation of debris and contaminants in and between the hardware of the conveyor bed. The system of the present invention may provide a more efficient and sanitary conveyor system for produce washing or other food processing application that requires less maintenance.
