Abstract
To avoid the passage of contamination from one bird to another at a poultry inspection station in a poultry processing shackle line and to eliminate the necessity for the inspector to touch the birds during the inspection, each bird in succession at the inspection station is automatically engaged and tilted to a breast-up, back-down generally horizontal position with the eviscerated body cavity facing the inspector. In such position, the body cavity is automatically expanded to a wide open condition for easy visual inspection while each bird traverses the inspection station, following which the bird tilting and body cavity expanding units are removed from contact with the birds and thoroughly cleansed near the back of the inspection station prior to automatically engaging other oncoming birds at the inspection station.
Claims17
A poultry inspection method comprising continuously moving birds through an inspection station with each bird hanging head downwardly and back forwardly toward an inspector at said station, each bird having an eviscerated body cavity whose entrance faces upwardly at the entrance to the inspection station, mechanically engaging each bird within said body cavity for automatically swinging each bird upwardly until each bird in turn is held in a generally horizontal position breast upwardly and back downwardly with the entrance of the body cavity facing the inspector, and mechanically engaging the entrance portion of said body cavity at the inspection station and expanding it to a wide open condition to provide a clear unobstructed view of the interior of said cavity, including the air sac area, the sex organ area, and the kidney area, and then disengaging each bird near the exit of the inspection station so that each bird will return automatically to a head down hanging position.
A poultry inspection method comprising moving birds in succession at a visual inspection station with each bird hanging by its hocks head downwardly with its back facing forwardly, automatically tilting each bird in succession to a generally horizontal position breast upwardly and with the eviscerated body cavity of the bird facing forwardly, and substantially immediately thereafter automatically widely expanding the entrance of said body cavity to facilitate a clear visual inspection of the interior of such cavity and maintaining each bird tilted and the entrance of said body cavity expanded for a sufficient time interval to allow adequate inspection.
A poultry inspection apparatus comprising a stationary frame having stationary camming means thereon, a coacting rotary frame having guided and movable cam follower means thereon defining plural spaced bird engaging mechanisms which move in synchronism with a poultry shackle line carrying plural birds suspended head downwardly from the shackles of said line, and each bird engaging mechanism comprising a first movable engaging element adapted to engage each bird with the eviscerated body cavity thereof to tilt each bird to a generally horizontal breast up position with the entrance of the body cavity facing an inspector, and each bird engaging mechanism comprising a second movable engaging element adapted to move into the entrance of said body cavity to expand it to a wide open condition to promote visual inspection of the interior of said cavity, said first and second engaging elements responding to movements of said cam follower means.
A poultry inspection apparatus comprising a poultry shackle line and a poultry inspection station in said line including a stationary member having stationary camming means and a coacting movable member having guided cam follower means moving in synchronism with said shackle line, the movable cam follower means comprising plural spaced bird manipulating mechanisms moving in synchronism with individual shackles of said shackle line, and each said mechanism comprising a first movable engaging element adapted to act automatically on each bird along the shackle line to tilt each bird to a generally horizontal breast up inspection position, and each mechanism additionally comprising a second movable engaging element adapted to engage and expand the entrance of the eviscerated body cavity of each bird to facilitate visually inspecting such body cavity at the inspection station.
