ABSTRACT:
Container diverter apparatus and method for displacement of selected containers on a conveyer for such purposes as rejection, sorting and the like. In accordance with the invention, a servo controlled actuator is positioned adjacent to the stream of containers on the conveyer, so as to be able to push selected containers to a different position across the width of the conveyer. The servo controlled actuator is controlled by a commanded position waveform, which may be tailored to the containers being deflected and which may be readily changed for different containers by use of a look-up table. Detection of the precise initial position of each container on the conveyer allows initial servoing of the actuator to a predetermined distance from the container prior to initiation of the ejection waveform, resulting in fast and precise displacement of selected containers in a highly reliable and very repeatable manner. Various embodiments are disclosed.
