As shown in FIGS. 1 and 2, the thoracic stripping device A in the upper half of the slaughtered hen is made with a notch through the shoulder joint from the thoracic fork bone to the scapula on the back side and along the sternal ridge. The upper half 100 of the scapula with a pair of cuts is fitted into the sternum of the upper 100 of the scapula from below to hold the upper 100 of the scapula, and forward as indicated by the white arrows in FIGS. 1 and 2. That is, the holding member 1 that moves in the dorsal direction of the upper half 100 of the slaughtered bird, the guides 2a and 2b that guide the holding member 1, and the left and right shoulder joints of the upper half 100 of the slaughtered bird that moves forward. More specifically, a pair of left and right upper and lower holding members 3 and 4 that vertically hold the portion between the oval joint ball 103 on the wing 102 side of the shoulder joint and the joint fossa 104 on the thoracic side of the shoulder joint. The left and right shoulder joints 101 are sandwiched between the pair of left and right upper and lower holding members 3 and 4, and the left and right wing 102s move forward with the left and right holding members 3 and 4 protruding outward. The wing movement blocking member 5 that abuts the bases of the left and right wings 102 of 100 from the front, that is, from the back side to prevent the left and right wings 102 from moving forward, and the bases of the left and right wings 102 by rotating the holding member 1. A cam 6 that tilts the upper half 100 of the scapula that is in contact with the scapula movement stop member 5 forward, that is, to the back side, and the wing movement prevention member 5 outside the pair of left and right upper and lower holding members 3 and 4. A pair of left and right push-up members 7 that are arranged near and at positions that do not interfere with each other and rotate around the axis of rotation in the left-right direction, and a pair of upper and lower holding members 3 and 4 on the left and right are arranged at the end portions that are the front ends. It includes a pair of left and right rotary blades 8 that rotate around a left-right rotation axis, and a pair of left and right swing arms 9 that are arranged between the pair of left and right rotary blades 8 and swing around the left-right rotation axis.
As shown in FIG. 1, the vertical gap between the pair of upper and lower holding members 3 and 4 on the left and right is a horizontal portion and an upwardly convex curve in order from the start end portion which is the rear end portion to the end portion which is the front end portion. A portion, a downwardly convex curved portion, and a horizontal portion are formed and extend.
The holding member 1 is provided with a driven portion 1a that engages with the guides 2a and 2b at the lower end portion, and is rotatable around a rotation axis 1b in the left-right direction.
The following left and right breast meat sorting mechanism is arranged in front of the rotary blade 8.
As shown in FIG. 3, the supporting arm 11 extends forward from the structural member 10 that supports the constituent member of the breast meat peeling device A in the upper half of the slaughtered bird. The support arm 11 is a plate member that passes above the intermediate position of the gap between the pair of left and right rotary blades 8 and extends forward of the rotary blade 8 perpendicular to the rotation axis of the rotary blade 8. The first receiving member 12a is attached to the right side of the support arm 11 and close to the rotary blade 8, and the second receiving member 12b is attached to the left side and farther from the rotary blade 8 than the first receiving member 12a. .. The first receiving member 12a and the second receiving member 12b are rectangular plate members extending vertically and vertically parallel to the rotation axis of the rotary blade 8. The lower half of the first receiving member 12a and the second receiving member 12b is inclined downward toward the rotary blade 8.
A conveyor belt B arranged directly below the first receiving member 12a and the second receiving member 12b extends in parallel with the rotation axis of the rotary blade 8.

The operation of the breast peeling device A in the upper half of the slaughtered bird will be described.
When the upper half 100 of the eclipse carcass moves forward as indicated by the white arrow in FIG. 1, the driven portion 1a of the holding member 1 engages with the guides 2a and 2b, and the left and right shoulder joints 101 form a pair of left and right upper and lower joints. By engaging with the upper and lower gaps between the holding members 3 and 4, the holding member 1 is tilted forward or backward in conjunction with the forward movement, and the upper half 100 of the poultry carcass is also tilted forward or backward. To do.
When the upper half 100 of the slaughtered bird approaches the starting end which is the rear end of the holding members 3 and 4, the upper half 100 of the slaughtered bird is tilted backward, that is, to the chest side, and the left and right shoulder joints 101 Descend. As a result, the portion between the left and right shoulder joints 101, more specifically, the oval joint ball 103 on the wing side of the shoulder joint 101 and the glenoid cavity 104 on the thoracic side of the shoulder joint, becomes the upper member 3 of the left and right holding members. It enters the horizontal portion of the upper and lower gaps between the lower member 4 and is sandwiched by the members.
As shown in FIGS. 2A and 2B, the shoulder joint 101 passes through the top of the convex curved portion above the vertical gap between the upper and lower holding members 3 and 4, and the portion of the downward inclination of the gap. At the time of reaching, the front edge of the lower end portion of the support member 1 comes into contact with the cam 6. As a result, as the support member 1 moves forward, the support member 1 and thus the upper half 100 of the slaughtered bird slaughter falls forward, that is, to the dorsal side. As shown in FIG. 2C, the support member 1 and thus the upper half 100 of the slaughtered bird slaughter collapses until it becomes substantially horizontal. When the upper half 100 of the slaughtered bird body moves forward and falls forward to a substantially horizontal position, the dorsal portion of the base of the left and right wing 102 abuts on the left and right wing movement blocking members 5 and moves forward. Movement is restricted. The body of the upper half 100 of the slaughtered bird slaughter continues to move forward and falls forward, that is, to the dorsal side. The body of the upper half 100 of the poultry carcass, which has a notch through the shoulder joint from the thoracic fork bone to the dorsal scapula and a pair of notches along the sternal ridge, has left and right wings 102. By moving to the dorsal side and falling to the dorsal side in a restricted movement state, the left and right wing 102 and the scapula, that is, the left and right scapula with the wing, are the torso of the upper half 100 of the poultry carcass. It is peeled off from.

Next, the wing movement blocking member 5 moves to a retracted position away from the holding members 3 and 4, and the left and right pushing members 7 rotate to abut the left and right wing 102 from the chest side, and the movement blocking member 5 and the left and right pushing members 7 come into contact with each other. The left and right wings 102 and the breast meat that have been disengaged are separated from the holding member 1. As a result, the left and right wings 102 and the breast meat are completely separated from the body. The left and right push-up members 7 push up the left and right wings 102 and the breast meat to the vicinity of the end portion which is the front end portion of the holding members 3 and 4. The left and right push-up members 7 rotate backward, and the wing movement blocking member 5 returns to the operating position close to the holding members 3 and 4.
The swing arm 9 swings from the retracted position shown by the alternate long and short dash line in FIG. 1 to the operating position shown by the solid line, abuts the left and right wings 102 and the breast breast, and moves the left and right wings 102 and the breast forward. Extrude. The left and right rotary blades 8 separate the left and right wings 102 from the left and right breast meat. The left and right wings fall from the rotary blade 8 and are collected by a conveyor belt (not shown).

The left and right breast meats 105b and 105a from which the wings 102 have been cut and removed are urged by the swing arm 9 and discharged from the rotary blade 8 diagonally forward and upward. As shown in FIG. 3, the left and right breast meats 105b and 105a are received by the left and right second receiving members 12b and the first receiving member 12a and fall onto the conveyor belt 13 directly below. The right breast 105a received by the first receiving member 12a close to the rotary blade 8 falls to a portion of the conveyor belt 13 close to the rotary blade 8 and is separated from the rotary blade 8 by the first receiving member 12a. 2 The left breast meat 105b received by the receiving member 12b falls to a portion of the conveyor belt 13 separated from the rotary blade 8. As a result, a row of the right breast meat 105a and a row of the left breast meat 105b are formed on the conveyor belt 13, and the left and right breast meats 105b and 105a are separately collected.
The first receiving member 12a and the second receiving member 12b, which are plate members extending vertically and parallel to the rotation axis of the rotary blade 8, have the effect of the breast meats 105a and 105b released from the rotary blade 8 in a parabolic manner. Can be taken as a target.
In the trimming work, which is a post-process, one of the workers facing each other with the conveyor belt 13 sandwiched between them processes the right breast 105a, and the other processes the left breast 105b. Since each worker only needs to process the right breast meat 105a or the left breast meat 105b, the work efficiency is improved. Since the right breast meat 105a and the left breast meat 105b are separately conveyed by a single conveyor belt 13, the processing plant area can be saved.

The left and right breast separation mechanism is not limited to the above.
