Description

Accumulating and Nonaccumulating roller conveyors are heavy duty belt driven live roller conveyors. Their 2-1/2″ diameter rollers include commercial grade bearings mounted on retained 5/8″ hex shafts. The rollers are lift out style and are mounted high in the frame. The rollers are driven through contact with an endless flat PVC covered belt. The belt runs the entire length of the conveyor and is pulled through the conveyor assembly by a shaft mounted gearmotor via a lagged drive pulley.

In nonaccumulating conveyor the conveyor belt is held in contact with the underside of the load carrying rollers by a series of fixed pressure rollers mounted beneath the belt. In accumulating conveyor the flat belt is held in contact by movable sets of pressure rollers when compressed air is applied to frame mounted air actuators below. These movable sets of rollers may also be selectively droped away, breaking contact between the belt and the load carrying rollers, thereby allowing loads to idle above.
