System is designed for elevating and lowering products in packets or small cartons when transported on the company's VarioFlow Modular Conveyor Systems. The elevators and lowerators combine a non-marring flocked chain with soft, overhead rollers to achieve gentle upward or downward product transport through vertical curves, including those with steep angles of incline or decline. The system provides a gentler and more appropriate option for crushable packages than a wedge conveyor, in addition to being more economical. To ensure gentle transport, soft overhead rollers apply light pressure to the product from above, securing it against the flocked chain surface to carry it through vertical curves and straight sections. The rollers are mounted to guiderail profile, which is custom contoured to each application. This design allows for optimum arrangement of the overhead rollers to match the needs of the product being conveyed, and adjustable guiderail brackets allow for easy field adjustment at any time. Inclining or declining sections can also be combined in one conveyor with horizontal transport at the lower and/or upper levels to reduce costs and system complexity.
