Abstract
A paw cutting system for removing a poultry paw from a shackle conveyed along a shackle conveyor line and then cutting the leg of the paw to remove the knuckle is provided. The paw cutter has a guide bar substantially aligned with the shackle conveyor line that urges the paw to a central cavity of the shackle. The paw is discharged from the central cavity into a lateral notch formed in two opposed discs positioned adjacent to an end of the guide bar. The two opposed discs are rotatable and move the paw from the guide bar to a blade. As the paw is moved to the blade, the two discs stretch the paw so that the blade can cleanly cut the paw. The cut paw product can be placed onto a belt or other device in an ordered manner.

A paw cutting system for removing a poultry paw from a shackle conveyed along a longitudinal axis on a shackle conveyor line, and then cutting the leg of the paw to remove the knuckle, the paw cutting system comprising:
- a guide bar positioned adjacent to and substantially aligned with a portion of the shackle conveyor line, wherein the guide bar is upwardly inclined relative to the shackle conveyor line such that a first end of the guide bar is spaced from the shackle conveyor line a first distance and a second end of the guide bar is spaced from the shackle conveyor line a second distance that is less than the first distance, wherein the guide bar is substantially linear, and wherein as the shackle is conveyed toward the second end of the guide bar, the poultry paw is urged by the guide bar from a proximal end of the shackle to a central cavity of the shackle;
- a holding wheel positioned adjacent to the second end of the guide bar, wherein the holding wheel defines a plurality of notches in an outer edge of the holding wheel, wherein each notch of the plurality of notches is configured to contain a portion of a paw therein, and wherein the holding wheel is configured to move the paw from the guide bar to a blade;
- a shackle element having an edge positioned at an acute angle relative to the longitudinal axis of the shackle conveyor line, wherein the shackle element is configured for urging the shackle away from the holding wheel relative to the longitudinal axis of the shackle conveyor line when the paw is positioned in the central cavity of the shackle;
- and
- the blade positioned adjacent to the holding wheel, wherein the blade is configured to cut the knuckle from the paw positioned in a notch of the plurality of notches of the holding wheel.
A paw cutting system for removing a poultry paw from a shackle conveyed along a longitudinal axis on a shackle conveyor line, and then cutting the leg of the paw to remove the knuckle, the paw cutting system comprising:
- a guide bar positioned adjacent to and substantially aligned with a portion of the shackle conveyor line, wherein as the shackle is conveyed from a first end toward a second end of the guide bar, the poultry paw is urged by the guide bar from a proximal end of the shackle to a central cavity of the shackle;
- a holding wheel comprising two opposed discs spaced from each other a predetermined wheel distance, wherein the two opposed discs are positioned adjacent to the second end of the guide bar, wherein a plurality of notches are defined in an outer edge of each of the two opposed discs, wherein each notch of the plurality of notches is configured to contain a portion of a paw therein, and wherein the two opposed discs are rotatable and configured to move the paw from the guide bar to a blade;
- a shackle element having an edge positioned at an acute angle relative to the longitudinal axis of the shackle conveyor line, wherein the shackle element is configured to urge the shackle away from the holding wheel at an acute angle relative to the longitudinal axis of the shackle conveyor line when the paw is positioned in the central cavity of the shackle;
- and
- the blade positioned adjacent to the holding wheel, wherein the blade is configured to cut the knuckle from the paw when the knuckle is in the predetermined wheel distance between the two opposed discs.
A method for removing a poultry paw from a shackle conveyed on a shackle conveyor line, and then cutting a leg of the paw to remove a knuckle, the method comprising:
- conveying the shackle along a longitudinal axis past a guide bar positioned adjacent to and substantially aligned with a portion of the shackle conveyor line, wherein as the shackle is conveyed from a first end toward a second end of the guide bar, the poultry paw is urged by the guide bar from a proximal end of the shackle to a central cavity of the shackle;
- discharging the poultry paw from the central cavity of the shackle into a lateral notch formed in two opposed discs spaced from each other a predetermined wheel distance to form a disc gap, wherein the two opposed discs are positioned adjacent to the second end of the guide bar, wherein the lateral notch is defined in an outer edge of each of the two opposed discs, and wherein two opposed discs are rotatable and configured to move the paw from the guide bar to a blade;
- stretching the poultry paw so that a claw of the paw is on an outside of a first disc of the two opposed discs, and the knuckle of the paw is on an outside of a second disc of the two opposed discs;
- and
- cutting the stretched poultry paw with a blade to remove the knuckle from the paw, wherein at least a portion of the blade extends into the disc gap.
