Bird wing cutting machine
A machine for cutting poultry wings into segments. Holders convey wings through a guide that positions the first joint between the drumette and midwing. A blade incises the connective tissue after the bones at the joint have been disarticulated by lateral guides that form a tapered corridor. A second joint at the midwing and wingtip is forced into a pocket by one of the lateral guides extending into the second joint. The second joint is severed by a blade extending into the second joint from the side opposite the lateral guide.
1. A cutting apparatus for cutting bird wings having a drumette segment, a midwing segment and a wingtip segment, the apparatus comprising:
(a) a plurality of connected wing holders for receiving wings, each wing holder having a central support for seating in a crotch of a first joint between the drumette and midwing segments of a wing;
(b) means for moving the wing holders through a path;
(c) a first guide mounted adjacent the path and having a groove facing the path for receiving the first joint of a wing and restricting movement of the first joint away from the wing holder;
(d) a pair of lateral guides mounted adjacent the path on opposing sides thereof, the lateral guides forming a tapered corridor for guiding the drumette and midwing segments of a wing toward one another, thereby pivoting the drumette and midwing around the central support, reducing an angle between the drumette and midwing and disarticulating the first joint;
(e) a first blade mounted in the path adjacent the groove, and a gap positioned between the first guide and the first blade into which the first joint can be conveyed by a corresponding wing holder, the first blade separating the drumette and midwing segments of a wing.
2. The apparatus in accordance with claim 1 , further comprising:
(a) a pocket in each wing holder into which a second joint between the midwing and wingtip segments of a wing can be disposed;
(b) one of said lateral guides being mounted in the path for extending into the crotch of the second joint and restricting wing movement away from the pocket;
(c) a second blade mounted in the path adjacent said one of said lateral guides and a gap positioned between said one of said lateral guides and the second blade into which the second joint is conveyed by a corresponding wing holder for separating the midwing and wingtip segments of a wing.
3. The apparatus in accordance with claim 2 , further comprising a first slot in the wing holder into which the first blade extends.
4. The apparatus in accordance with claim 2 , wherein the slot is formed in the central support.
5. The apparatus in accordance with claim 3 , further comprising a second slot in the wing holder into which the second blade extends.
6. The apparatus in accordance with claim 5 , wherein the pocket is formed by a surface of the wing holder and a wingtip guide.
7. The apparatus in accordance with claim 6 , wherein the wingtip guide has a ramp-shaped edge.
8. The apparatus in accordance with claim 7 , wherein the groove faces downwardly.
9. The apparatus in accordance with claim 8 , wherein the first and second blades are mounted to a stationary object.
10. A cutting apparatus for cutting bird wings having a drumette segment, a midwing segment and a wingtip segment, the apparatus comprising:
(a) a plurality of connected wing holders for receiving wings, each wing holder having a central support for seating in a crotch of a first joint between the drumette and the midwing segments of a wing;
(b) a drive motor linked to the connected wing holders for moving the wing holders through a path;
(c) a first guide mounted above the path and having a groove facing downwardly toward the path, the groove adapted to receive the first joint of a wing and restricting lateral movement and vertical movement of the first joint away from the wing holder;
(d) a pair of lateral guides mounted on opposite sides of the connected wing holders and having surfaces facing the connected wing holders, at least one of the surfaces tapering for guiding at least one of the drumette and midwing segments of a wing toward one another, thereby pivoting at least one of the drumette and midwing around the central support, reducing the angle between the drumette and midwing and disarticulating the first joint;
(e) a first blade extending at least partially through the connected wing holders adjacent the groove and forming a gradually narrowing gap between the first guide and the first blade into which the first joint can be conveyed by a corresponding wing holder for separating the drumette and midwing segments of a wing;
(f) a tapered, upwardly-facing pocket in each wing holder adjacent the central support and into which a second joint between the midwing and wingtip segments of a wing can be disposed;
(g) one of said lateral guides mounted in the path and extending toward the pockets for extending into the crotch of the second joint and restricting lateral and vertical wing movement;
(h) a second blade extending at least partially through the connected wing holders adjacent said one of said lateral guides and forming a gradually narrowing gap between said one of said lateral guides and the second blade into which the second joint is conveyed by a corresponding wing holder for separating the midwing and wingtip segments of a wing.
11. The apparatus in accordance with claim 10 , further comprising a first slot in the central support of the wing holder into which the first blade extends, and a second slot in the wing holder into which the second blade extends.
12. The apparatus in accordance with claim 11 , wherein the pocket is formed by a surface of the holder and a wingtip guide, wherein the wingtip guide has a ramp-shaped edge.
13. The apparatus in accordance with claim 12 , wherein the first and second blades are mounted to a stationary object.
