One of the earliest designs for accumulation or unscrambling is the rotary table. Both configurations can handle multiple container sizes and materials. The rotary design is flexible and effective. Typical diameters are 30?, 36?, 42” and 48”. Top discs are stainless steel with machined backer plates for trueness. Accumulators are usually supplied with an enclosed cabinet and variable speed controls, using either DC or VFD controllers. Infeed and discharge conveyors are recommended to be designed with a close interface for smooth transfers. A smooth edge bowl top is available for hand packing applications.
