Abstract
An automatic article stacking system wherein a plurality of articles to be stacked are arranged in layers prior to being stacked. The layers are advantageously arranged horizontally orthogonal to one another so as to enhance the stability of the stack. A measurement system is provided for determining whether any of the articles exceeds a predetermined size limit. In one embodiment which is arranged for stacking egg cartons, a determination that the egg carton exceeds the predetermined size limit signifies that the egg carton is open and, therefore, not in a form suitable for stacking. The open egg carton is conveyed under an elevator which accumulates the articles to be stacked, and to a discharge area. Thus, closed egg cartons are accumulated in layers and stacked. Successive layers of articles are stacked under prior stacked layers.
