Shackle with pivot feature & conveyor system therefor
A device ( 10 ) for retaining and associating an animal with a transport system during transport to and through one or more processing operations along a processing line. The device ( 10 ) includes a pivot mechanism ( 12 ) for reliably controlling the orientation of the animal during upward and downward travel on the transport system. More specifically, the device includes a lower portion ( 14 ) for retaining the animal, and an upper portion ( 16 ) for coupling with the transport system. The lower portion ( 14 ) is pivotably coupled with the upper portion ( 16 ) and movable between a first position in which the lower portion ( 14 ) and the upper portion ( 16 ) are in a substantially straight orientation relative to each other, and a second position in which the lower portion ( 14 ) and the upper portion ( 16 ) are in a substantially angled orientation relative to each other in the forward direction.
1. A shackle for retaining a poultry animal on a conveyor system for moving the poultry animal in a forward direction, the shackle comprising:
an upper portion operable for conveyance by the conveyor system;
a lower portion including stirrups operable to receive and retain the legs of the poultry animal, the lower portion being movably attached to the upper portion; and
a stop defining at least one position in which the lower portion and the upper portion are in a substantially straight orientation relative to each other.
2. A shackle for retaining a poultry animal on a conveyor system for moving the poultry animal in a forward direction, the shackle comprising:
a lower portion including a pair of stirrups operable to receive and retain the legs of the poultry animal;
a leg extending upwardly from the lower portion; and
an upper portion operable for conveyance by the conveyor system, the lower portion being movably attached to the upper portion, and
wherein the leg contacts a portion of the conveyor system and defines a position in which the lower portion and the upper portion are in a substantially straight orientation relative to each other.
3. An animal retention device for coupling to a conveyor system, the device comprising:
a first stirrup and a second stirrup operable to receive and retain an animal;
a suspension member substantially rigidly coupled to the first stirrup and the second stirrup, the suspension member having a stop; and
the stop defining at least one position of the device.
4. The device according to claim 3 , wherein the device is configured to be coupled to a pivot mechanism, the pivot mechanism coupled to a conveyor system, and the pivot mechanism operable for relative movement between two positions.
5. The device according to claim 3 , wherein the device is configured to be coupled to a pivot mechanism, the pivot mechanism coupled to a conveyor system, and the pivot mechanism operable to define two positions.
6. The device according to claim 3 , wherein the device is configured to be coupled to a pivot mechanism, the pivot mechanism coupled to a conveyor system, and the pivot mechanism operable to control the orientation of an animal during travel on the conveyor system.
7. A conveyor system for retaining and moving animals in a forward direction for processing, the system comprising:
a plurality of independent shackles in series, wherein the plurality of independent shackles are chainless,
at least one change in elevation, through which the plurality of independent shackles maintain a substantially vertical orientation,
a second change in elevation which is an upward incline and the plurality of independent shackles maintains an orientation substantially perpendicular to the conveyor system.
8. The conveyor system according to claim 7 ,
wherein at least one of the plurality of shackles is associated with a spacing mechanism operable to keep the plurality of shackles separated during the at least one change in elevation, and
the spacing mechanism is coupled to the conveyor system and is associated with a stop to define at least one position of the at least one of the plurality of shackles.
9. The conveyor system according to claim 7 , wherein at least one of the plurality of independent shackles comprising:
a lower portion operable to retain the animal,
wherein the lower portion comprises first and second stirrups;
an upper portion operable for conveyance by the conveyor system, and the upper portion attachable to the lower portion,
wherein the lower portion and the upper portion are operable for relative movement between—
(a) a first position in which the lower portion and the upper portion are in a substantially straight orientation relative to each other, and
(b) a second position in which the lower portion and the upper portion are in a substantially angled orientation relative to each other;
the lower portion substantially inhibited from moving in a rearward direction beyond an orientation in which the lower portion is substantially straight relative to the upper portion.
10. A conveyor system for retaining and moving animals in a forward direction for processing, the system comprising:
a plurality of independent shackles in series, wherein the plurality of independent shackles are devoid of a spacing chain,
at least one change in elevation, through which the plurality of independent shackles maintains a substantially vertical orientation,
a second change in elevation which is an upward incline and the plurality of independent shackles maintains an orientation substantially perpendicular to the conveyor system.
11. A conveyor system for retaining and moving animals in a forward direction for processing, the system comprising:
a plurality of independent shackles in series, wherein the plurality of independent shackles are associated solely by a transport system,
at least one change in elevation, through which the plurality of independent shackles maintains a substantially vertical orientation, and
a second change in elevation which is an upward incline and the plurality of independent shackles maintains an orientation substantially perpendicular to the conveyor system.
