Abstract:
1. An automated destacking device comprising: a frame member; a hopper for receiving a stack of generally flat articles, said hopper being attached to said frame member and being movable in a vertical direction; an elevator member attached to said frame for driving said hopper upwardly and downwardly with respect to said frame member; a rotary actuator attached to an upper portion of said frame member; a pivoting arm operatively connected to said rotary actuator; a carriage movably connected to said pivoting arm, so that said carriage may move in a horizontal direction between a first position and a second position, wherein said carriage also includes at least one contact plate on an underside thereof, and wherein said contact plate includes an adhesive element on an underside thereof for engagement with a flat article; and a programmable logic control operatively connected to said elevator and said rotary actuator for controlling the movements and timing thereof; wherein said elevator drives said hopper upwardly to a predetermined level until a generally flat item on top of a stack of said flat items comes into contact with said adhesive element on said contact plate; and a pair of horizontally disposed guide rods attached to said frame member, wherein said carriage is operatively connected to said guide rods so that said carriage is movable in a horizontal direction along said guide rods; wherein said rotary actuator causes said pivoting arm to move in a first direction, thereby causing said carriage to move in a horizontal direction carrying said generally flat item from said first position to said second position.
