Apparatus for stacking formed articles

摘要

An improved stacking apparatus which is particularly well suited for receiving formed polymeric articles from appropriate forming apparatus and arranging these formed articles in stacked nested relationship with each stack containing a predetermined number of such articles so as to thereby facilitate accurate packaging of the formed articles for shipment. The stacking apparatus includes a plurality of independently controlled elevator and exit gating members which may be easily and readily positioned in various spaced relationships so as to enable the stacking apparatus to handle a wide variety of different sized formed articles. Because each of the elevator and gating members is independently actuable, the stacking apparatus is able to release individual nested stacks of formed articles containing the desired predetermined number without regard to whether or not adjacent stacks have received the same number of formed articles.
