Abstract
In the conveyor system disclosed herein, a plurality of elongate lifting assemblies are interleaved with parallel moving belts on which articles are transported. Each lifting assembly utilizes an air bag which is supported in an upwardly facing, rigid, U-shaped channel and which, when inflated, lifts a longitudinally-flexible, inverted, U-shaped channel member. The channel members include respective lips which engage and locally limit upward movement of the inverted channel member to a height sufficient for lifting articles on the conveyor out of driving contact with the moving belts. The ends of the inverted channel members are fixed or fastened with the upper surface of that part of the inverted channel below the level of the moving belts. Accordingly, when the air bags are inflated, the moving belts can drive successive articles up on to the resulting ramp surface of the inverted channels without developing crushing pressures between adjacent articles.
