ABSTRACT:
Facilities are associated with the discharge end of an article stacker, suitable for use in container-filling applications, so that the articles are discharged from the stacker in discrete groups of N articles each. A system of horizontally extending projections are provided on a pair of cylindrical blocking members that act as escapement devices at the bottom of the stacker. The successive projections on the cylindrical blocking members are cyclically moved into engagement with the lower ends of peripheral rims on the N lowermost articles in the stack, after which the N engaged articles are successively discharged from the bottom of the stacker. During the engagement and discharge of the N lowermost articles, the stacked articles overlying the lowermost N articles are inhibited from downward movement in the stacker. After the discharge of the lowermost N articles, the next N articles in the stack are moved downwardly into operative position for discharge after a predetermined interval.
