A slip roller conveyor has a frame comprising a pair of parallel, spaced-apart side plates. Secured to each of the side plates is a plurality of annular rollers with a predetermined pitch distance between adjacent rollers. The annular rollers have tubular sleeves of a lesser diameter projecting outward from a side surface thereof. The tubular sleeves on an opposed pair of annular rollers fit into the lumen of a longer tubular roller with a clearance fit. The annular rollers on each of the side plates are driven by an endless belt that also surrounds a motor-driven nose roller.

Long roller slip conveyor

The conveyor apparatus disclosed herein is generally formed of a first rail and a second rail, each rail having a plurality of rollers. A portion of the rollers are desirably drive rollers, receiving power from an integral motor assembly. The motor generally comprises a stator that is coupled to the rail and an outer roller assembly rotatably coupled to the rail. The roller assembly includes an outer circumferential magnetized portion positioned in surrounding engagement to the motor stator and functions both as the motor rotor and the conveying surface of the roller. Non-slip roller covering material may be attached to the exterior of the roller assembly. A circuit board having logic controls is preferably in communication with at least one sensor and the motor rotor to regulate rotation of the motor rotor during use of the conveyor.
