Abstract: This conveyor system provides head-to-head or head-to-tail placement of product. More specifically, the system is configured to use the minimum acceleration necessary to perform the targeted spacing. Feedback control continuously readjusts acceleration to perform the given work. The system uses one or more contiguous variable speed conveyors that work together to space items by a calculated amount at each output juncture attempting minimum acceleration necessary to perform the given work. During product transition, an acceleration match is made with downstream conveyor where additional spacing correction can occur. Feedback control is used to continually readjust acceleration as necessary to meet spacing requirements.
