Study of the automated transfer of live birds to shackle line
Research funded by the U.S. Poultry & Egg
Association studied the intelligent automated transfer of live birds to the
The study, costing an investment of over US$3 million, is part of the
Association's industry research program involving broiler, turkey and commercial
The focus of the project was aimed at methods to integrate the processes of
grasping birds from the moving conveyor, correcting their orientation, and
loading both feet of the bird accurately onto the mechanical inverter for
subsequent shacking and humane killing. Three specific tasks were
-> The development of an overhead conveyor for transporting a number of
equally spaced graspers, each of which consists of a pair of rotating hands, as
well as the mechanism that grasps a bird from the moving conveyor. The
mechanical hands continuously cradle the bird for the consequent processes.
-> The development of a vision-guided magnetic
actuator to correct the orientation of the grasped bird, as well as improvements
on the vision system.
-> A design to provide a means to render a
mechanically cradled bird insensitive to pain before shackling its feet and
inverting its body.
