Abstract
Abstract A gripping head for loading packages into a crate is disclosed having a number of support members attached to a frame. The support members each have a predetermined number of pneumatically operated suction cups for gripping packages that are intended for loading into a crate. Two of the support members are capable of pivoting movement on the frame in response to vertical movement of a center support member so as to allow the gripping head to deposit the packages into the crate in a manner that is economical and that allows efficient use of the crate space.
