A transfer module for a universal sorting conveyor has a ball belt looped around two pulley assemblies mounted to a frame and driven in a machine direction. Two bi-directional cross-belt assemblies are mounted to the frame to provide two smooth surfaced belts each supported on a roller bed. The belts extend beneath and engage the ball belt to advance a conveyed parcel in the cross direction. Each cross belt assembly has internal motorized drive rollers at the ends and a multiplicity of closely spaced idler rollers of smaller diameter than the drive rollers which define the roller bed, with a spacing between the idlers rollers of less than one inch. The ball belt has a plurality of plastic link bodies pivotally connected to one another, each with a downwardly opening socket having downwardly facing entry notches which allow distortion of the socket for entry of a ball therein.

B65G 39/12 - Arrangements of rollers mounted on framework
A conveyor has looped conveying belts extending between grooved inlet and outlet rollers mounted to a frame, these rollers driven by motorized drive rollers. Each belt has an outwardly facing surface which engages a conveyed article, and an inwardly extending protrusion which engages the grooves of rollers rotatably mounted between parallel plates. The plates extend downwardly to be fixed to cross members which extend between the sides of the frame. A subframe supports upper rolls which are driven by belts connected to lower rolls, including motorized drive rolls. The subframe is mounted to an elevator platform to move the upper rolls between a retracted position and an extended position in which the upper rolls extend beyond the conveying belts which pass through gaps between the upper rolls, such that a conveyed article is moved by the upper rolls in a direction perpendicular to the direction of the conveying belts.

B65G 47/54 - Devices for transferring articles or materials between conveyors, i.e. discharging or feeding devices between conveyors which cross one another at least one of which is a roller-way
A transverse belt drive assembly has multiple belt drive frames spaced in a first direction and positioned between the rollers of a main conveyor which advances articles in the first direction. The belt drive frames support looped toothed belts which are advanced in a second direction perpendicular to the first direction. The belt drive frames are mounted to a platform which is driven on demand by an actuator to raise the belt drive frames to extend up above the roller surfaces of the main conveyor rollers causing the belts to engage articles carried on the conveyor rollers, lifting and advancing the articles in the first direction to transfer them off the conveyor rollers. Each belt has a body with converging walls and is received within a channel within a converging side wall track mounted to a belt drive frame. Rotatable bearings are mounted beneath each channel to support the belt.
