ABSTRACT:
A device and method are disclosed for moving articles, such as cans, by groups, or tiers, from a pallet to an adjoining surface, such as a belt conveyor. A pair of sweep arms of a sweep unit move about a closed loop path to alternately engage the trailing portion of groups of articles when at a pallet sweep area to urge each group from the pallet. A pivotable retainer arm of a retainer unit, mounted on a reciprocating carriage moved by a driver following a closed loop path, engages the leading portion of the group of articles to be then moved from the pallet and thereafter leads the group from the pallet. The sweep and retainer arms are simultaneously moved by cycles whereby the sweep arms are alternately moved from a home position to engage the trailing portion of a group of articles and urge the engaged group from the pallet and the retainer arm is moved from a home position in a direction opposite to movement of the sweep arm to engage the leading portion of the group of articles with the retaining arm being thereafter moved in unison with the sweep arm to lead the group from the pallet.
