ABSTRACT:
There is disclosed a multi-lane destacking machine in which stacks of nested articles in each lane are fed, one at a time, through an opening to drop to a shuttle platform. A clamp mechanism grips a stack on the shuttle platform, and the platform is retracted. A stripper mechanism, which has sharp, pointed edges on stripper arms to penetrate the interstice between the bottom article and the article nested therewith, advances to dislodge the bottom article of the stack onto a surface in front of the retracted shuttle platform. When the shuttle platform is advanced to again support the stack upon release of the clamp mechanism, the previously dislodged article is moved from under the stripper mechanism into a discharge lane by the shuttle platform. When the stripper mechanism is retracted, the stripper arms, which are normally biased toward each other, engage a stationary stop to spread apart.
