Abstract
An apparatus for transferring individual trays of eggs from the top of adjacently spaced stacks onto a conveyor member. A lifting head is provided for each stack of egg trays and includes thereon vacuum cups which are engagable with each of the individual eggs in the uppermost tray. A vacuum actuated gripper is further provided with each lifting head assembly for engaging and lifting the uppermost tray away from the remainder of the stack. Each lifting head assembly is associated with a rotatable drive to effect rotation during transfer while also moving adjacently spaced lifting head assemblies with respect to one another in order to avoid contact during simultaneous rotation of adjacent lifting head assemblies. Relative movement between each head assembly and the respective support platform is also provided to accommodate variations in height between adjacent stacks to insure proper engagement with the uppermost tray to be transferred.
