System for forming layers of packages to be palletized, and palletization plant thereof

摘要

A gripping head (1) comprises a supporting element (11), e.g. a horizontal plate, adapted to rotate about a first rotation axis (&alpha,-) with which two or more grippers (12) are pivotally associated, so that each gripper is adapted to rotate about a symmetry axis (β) thereof, said rotation axes being parallel to each other, and being the rotation motion of each gripper independent from the others. Therefore, each gripper is adapted to rotate about a symmetry axis (β) thereof and revolve about the rotation axis (α) of the supporting element with which they are pivotally associated. A preferred plant, comprising said gripping head (1), comprises a belt conveyor and a mechanical limb (2) with which said gripping head (1) is pivotally associated.
