Abstract
Chamber bank for use in a sorting operation includes chambers for receiving a receptacle therein. Each chamber is defined by a floor, a left wall, a right wall, and a rear wall that together define a receiving space for a receptacle. At least one of the left and right wall is taller than the corresponding abutting side wall of the receptacle received therein. A system assigns a first number of articles occupying a first volume to the receptacle such that the first number of articles overfills the receptacle when all of the first number of articles are deposited thereinto.
