JP-A-10-150912

In the device of Patent Document 1, in the state where the torso is twisted so that the back is centered on the hip joint and the abdomen is downward, the hip joint is only dislocated, and the femoral head is not relaxed. There is a problem that it is not completely detached from the acetabulum.
The present invention has been made in view of the above problems, and a cut is made at the boundary between the abdomen and the inside of the thigh and the back, and the torso is twisted around the hip joint so that the back is inserted upward. It is an object of the present invention to provide a edible carcass hip dislocation device capable of completely dislocating the hip joint of a poultry carcass that is advanced by being hung by the ankle gripped by a shackle with the abdomen facing downward And

In order to solve the above problems, in the present invention, a cut is made in the boundary between the abdomen and the inner side of the thigh and the back, and the torso is twisted around the hip joint so that the back is directed upward. With the ankle gripped by the shackle with the abdomen pointing downwards, the chain conveyor with a blade that supports the abdomen of the poultry carcass that is suspended and advanced from below, and the back of the poultry carcass A poultry bird carcass comprising: a guide member that presses the back portion downward; and a torsion biasing member that abuts the inside of the thigh of the poultry carcass and twists the inner side of the thigh outward. A hip dislocation device is provided.
In the present invention, the inner side of the thigh is twisted outward while suppressing the rotation of the torso by the guide member and the chain conveyor with blades, so that the back part is upward and the abdomen part is downward with the hip joint as the center. The hip joint that has been in the subluxation state as a result of the torso being twisted is completely dislocated.

In a preferred embodiment of the present invention, the torsional biasing member is a disk that is rotatable about an axis that is orthogonal to the direction of travel of the poultry carcass.
If the axis of rotation of the disc is perpendicular to the direction of travel of the carnivorous carcass, the peripheral edge of the disc abuts the inside of the thigh, so the disc twists and urges the inside of the thigh and follows the advancement of the thigh. Then rotate. Therefore, the disk does not unduly prevent the thigh from moving forward. As a result, the dislocation operation of the hip joint is performed smoothly.

In a preferred aspect of the present invention, the axis is directed obliquely upward toward the outer side of the thigh.
Both thighs, which are hung with their ankles gripped by shackles, are open in an inverted eight-letter shape. If the rotation axis of the disc is directed obliquely upward toward the outer side of the thigh, the plane containing the disc is perpendicular to the direction in which the thigh extends, so that an external force can be effectively applied from the disc to the thigh. .

In the poultry carcass hip dislocation device according to the present invention, the inside of the thigh is twisted outward while the rotation of the torso is suppressed by the guide member and the chain conveyor with the blade, so that the back part is centered on the hip joint. As a result of the twisting of the torso so that the abdomen is downward, the hip joint that has been in the subluxation state is completely dislocated.

A poultry carcass hip dislocation apparatus according to an embodiment of the present invention will be described.

A poultry carcass hip dislocation apparatus according to a first embodiment of the present invention will be described.
As shown in FIG. 1, the poultry carcass C includes a trunk C3 including an abdomen C1 and a back C2, and a pair of thighs C6 extending from the hip joint C4 to the ankle C5. A cut L1 is made at the boundary between the abdomen C1 and the inside of both thighs C6, and a cut L2 is made at the center line of the back C2.
The poultry carcass C has the torso C6 in a state where the torso C3 is twisted around the hip joint C4, the hip joint C4 is sub-dislocated, the back C2 is directed upward, and the abdomen C1 is directed downward. Is opened in the shape of an inverted eight, and both ankles C5 are gripped by the shackle S, suspended and advanced in the direction of the white arrow.
The poultry carcass hip dislocation apparatus is in contact with the chain conveyor 1 with a single blade that supports the abdominal part C1 of the poultry carcass C from below and the back part C2 of the poultry carcass C, and the back part C2 is moved downward. A bar-shaped guide member 2 to be pressed and a pair of torsional biasing members 3 that abut on the inner side of the thigh C6 of the poultry carcass C and twist the inner side of the thigh C6 outward.
The torsional biasing member 3 includes an upper small-diameter disk 3a, a lower large-diameter disk 3b, and a shaft member 3c that passes through the centers of both disks and is fixed to both disks. The shaft member 3c extends perpendicular to the advancing direction of the poultry carcass C and is directed obliquely upward toward the outside of the thigh C6. The lower end of the shaft member 3c is rotatably supported by a support member (not shown).

The operation of the poultry carcass hip dislocation apparatus according to this embodiment will be described.
As shown in FIG. 1, the torsion biasing member 3 is configured such that the centerline of the abdomen C1 is bitten into the blades of the chain conveyor 1 with blades and the back C2 is pressed against the guide member 2 as shown in FIG. To approach. The hip joint C4 is subluxed and the femoral head is not completely detached from the acetabulum.

When the poultry carcass C further advances, as shown in FIG. 2, the small-diameter disk 3a and the large-diameter disk 3b of the torsional biasing member 3 come into contact with the vicinity of the cut L1 inside the thigh C6.
Since the shaft member 3c is orthogonal to the advancing direction of the poultry carcass C, the peripheral edge of the small diameter disk 3a and the peripheral edge of the large diameter disk 3b are in contact with the inside of the thigh C6. Since the shaft member 3c is directed obliquely upward toward the outside of the thigh C6, the plane including the small-diameter disk 3a and the plane including the large-diameter disk 3b are those of the thigh C6 opened in an inverted octagonal shape. It is orthogonal to the extending direction.
When the poultry carcass C further advances, the small-diameter disk 3a and the large-diameter disk 3b of the torsion biasing member 3 push the hip joint C4 while pushing the vicinity of the cut L1 inside the thigh C6 backward. Twist in the direction of the white double arrow in the center, that is, outward. Since the plane including the small diameter disk 3a and the plane including the large diameter disk 3b are orthogonal to the extending direction of the thigh C6, an external force is effectively applied to the thigh C6 from the small diameter disk 3a and the large diameter disk 3b. Is done.
The trunk C3 is sandwiched between the chain conveyor 1 with the blade and the guide member 2 and is restricted from rotating around the vertical axis and the horizontal axis, and is driven by the chain conveyor 1 with the blade to move forward. At the hip joint C4 in which the femoral head C4 ′ has been about to be detached from the acetabulum C4 ″, the femoral head C4 ′ is twisted in the direction of the white double arrow and posterior to the acetabulum C4 ″. And begins to completely disengage from the acetabulum C4 ″.
The small-diameter disk 3a and the large-diameter disk 3b whose peripheral portions are in contact with the thigh C6 are rotated in the direction of the double arrow following the advance of the thigh C6. Therefore, the torsion biasing member 3 does not excessively prevent the thigh C6 from moving forward. As a result, the dislocation operation of the hip joint C4 is performed smoothly.

When the poultry carcass C further advances, as shown in FIG. 3, the vicinity of the cut L1 on the inner side of the thigh C6 is further pushed backward in the moving direction and twisted outward. As a result, at the hip joint C4, the femoral head C4 ′ is completely detached from the acetabulum C4 ″.

The poultry carcass C has a cut L1 at the boundary between the abdomen C1 and the inner side of both thighs C6, a cut L2 at the center line of the back C2, and the hip joint C4 is completely dislocated and the femoral head C4. 'Is detached from the acetabulum C4 ", so that the torso C3 and both thighs C6 are no longer weakly connected by a part of the muscular tissue. Both thighs C6 are easily removed from the torso C3.
