US Patent 8414042 Articulating package palletizing system

A package moving system has a jaw device movable between an open and a closed position. The jaw has a pair of opposite support structures that each support at least one support arm. The at least one support arm moves between a first and second position. In the first position, it receives a package. In the second, it supports the package. At least one retaining member is biased downward to engage the package when the jaws are in a closed position. The retaining element urges against an upper surface of the supported package to retain the package in the support arms.
