2. Description of the Related Art In recent years, large-scale breeding, slaughtering, and processing of carcasses of edible birds and animals have become large-scale, and various types of automation have been performed. Recently, detachment of thigh meat from carcasses of edible birds and animals has been performed manually, and suitable deboning methods and deboning devices have been previously proposed by the present inventors for deboning of separated thigh meat. .

[0003]

Conventionally, the breast of the chicken for meat was peeled off from the upper body of the beetle after the thigh was cut off.
There is a problem that the meat remaining between the cut breast and clavicle tends to be damaged during the stripping operation, thereby lowering the commercial value. In addition, it is necessary for the worker to directly touch the meat with his / her finger, and there is a problem that the management cost in terms of the yield and the food hygiene is relatively high.

When the breast 10a is observed, as shown in the perspective views of FIGS. 5 and 6, an ideal cut surface 35 (streak) exists around the shoulder joint 11, and the muscle of the body 10b is a shoulder joint. 11 connects to the humerus, which connects to the scapula glenoid 11b, while the breast 10a passes through the pectoral muscle,
The wings 12 are also connected to the shoulder joint 11 via the upper arm muscles, and the breast 10a is formed between the upper part of the scapula 11a, the ostium 13 and the collarbone 14. In addition, the shoulder joint 1
As shown in FIG. 6, reference numeral 1 denotes a ligament, a tendon, a muscle, an articular membrane, etc., which connects a humeral head (not shown) which fits into a glenoid fossa 11b of a scapula 11a having a clavicle 14 and an ostium 13. Has been

Of the tendon, ligament, muscle, and articular membrane connecting the scapula 11a and the humeral head 12a at the time (hereinafter referred to as shoulder joint incision). Yield depends greatly,
In other words, a good yield can be obtained if the score and the depth are appropriate regardless of the size of the beetle. For this purpose, it is necessary to always appropriately set the insertion position and the creasing depth of the cutter, which is the creasing portion, in accordance with the size of the beetle flexibly.

As a result of a detailed study of the relationship between the position of the tendon, which is a living tissue to be creased, and the size of the beetle, the following conclusions were obtained as a result of a detailed examination using a skeletal morphology diagram. 1, ie, FIGS. 7 (A), 7 (B) and 7 (C) show a chest front view, a side view and a rear view of the formation of a skeletal structure of a beetle, and FIGS. 8 (A) and 8 (B) 7B show enlarged views of the circles D and E of the shoulder joint site shown in FIGS. 7B and 7C, respectively. 8A and 8B, the following matters are recognized. A, the scapula head 11c and the humeral head 12a are two sets of tendons (a)
And the tendon (b). b, As seen in the rear view of FIG. 2B, the tendon (a) is located outside the tendon b, and the tendon (a) extends obliquely outward from the scapula head 11c with respect to the humeral head 12a. The tendon (b) extends substantially vertically below the humeral head 12a from the scapula head 11c. 2. Next, when examining the insertion position of the creasing cutter, as shown in FIG.
c and the horizontal reference plane Xa is set on the upper surface of the scapula head 11c, the insertion position of the skewing cutter 16 is located at a distance Sa from the vertical reference plane Ya, and the horizontal reference plane Xa It is at a distance of Ha. By the way, these Sa,
As for the value of Ha, the variation with respect to the fluctuation of the beetle size is 2
It is almost negligible because it is only 3 mm. Therefore, the position of the vertical reference plane Ya is appropriately changed with respect to the size of the beetle, which is a workpiece, while the insertion position of the skew cutter 16 is set at a fixed position with respect to the vertical reference plane Ya that is changed each time. For example, the insertion position of the skewing cutter 16 can be set to a substantially appropriate position, but it has been understood that the problem lies in the method of setting the vertical reference plane for the change in the size of the work. Further, the a
As described in the section, the cutting of the living tissue of the shoulder joint may be performed on two sets of tendons (a) and tendons (b), and as described in the section b, the cutting of the tendon (a) is performed in a diagonally outward direction.

However, unless otherwise specified, the dimensions, shapes, relative positions, and the like of the components described in this embodiment are not intended to limit the scope of the present invention, but are merely illustrative examples. Absent. FIG.
FIG. 1 is a diagram showing a schematic configuration of a breast separating apparatus automatically corresponding to the size of a chicken carcass upper body used in performing a breast separating method for automatically coping with the size of the chicken carcass upper body of the present invention. FIG. 2 is a perspective view showing a schematic configuration of the guide bar of FIG. FIG. 3 is a view showing a situation change of a cutter insertion position corresponding to a size of a beetle as a work. FIG. 4 is a view showing a situation in which two sets of tendons connecting a scapula head and a humerus head are cut by the apparatus of FIG. In the drawings, FIG. 1A shows a cut of a tendon (a), and FIG. 1B shows a cut of a tendon (b).

According to the breast separating method of the present invention, which automatically corresponds to the size of the upper body of the chicken carcass, the insertion position of the cutter for scoring due to the difference in the size of the work which is a beetle when scoring the shoulder joint. And the insertion depth fluctuates, and the yield is greatly affected by the quality of the creasing. In other words, a good yield can be obtained if the crease portion and its depth can be set appropriately regardless of the size of the work. Therefore, the present invention enables the insertion position and the creasing depth of the cutter, which is the creasing portion, to be always set appropriately in accordance with the size of the beetle, which is the work, flexibly. That is, as shown in FIG. 3, when setting the insertion position of the skewing cutter 16 for scoring, the vertical reference plane Ya is set inside the shoulder joint, and the horizontal reference plane Xa is set on the upper surface of the shoulder joint. The insertion position is set at a position Sa outside the vertical reference plane Ya and at a position Ha below the horizontal reference plane Xa. By the way, Sa and Ha are affected by the variation of the size of the scapula head 11c, and the variation of the values is within 2 to 3 mm, and the influence of the variation of the beetle size is small.

Therefore, as shown in FIG. 1, the present invention minimizes the influence of the size of the work which is a bevel when setting the reference plane, especially when setting the vertical reference plane Ya, so that each of them corresponds to the size of the work. A plurality of guide bars 21 having an appropriate size S are prepared. As described above, the guide bar 21 has the size S
And the stoppers 21b, 21b provided on the upper surface of the distal end portion of the guide bar 21.
Thus, the position in the height direction at the time of insertion pressing is regulated. Therefore, the guide bar 21 having a size S corresponding to the size of the work is used, and the vertical reference plane Ya is set by inserting and pressing the work inside the shoulder joint of the work so as to appropriately spread the work in the direction of the arrow. The horizontal reference plane Xa can be set by the stopper 21b. It should be noted that the skew cutter 16 (not shown) is
The oblique sliding mechanism is provided so that the cutting edge of the skew cutter 16 is always located at Sa and Ha from both the vertical and horizontal reference planes. It is made possible.

Next, to cut the tendon connecting the scapula head 11c and the humeral head 12a, as shown in FIG.
23 extends obliquely outward from the scapular head 11c with respect to the humeral head 12a, and the tendon (b) 24 extends substantially vertically downward inside the tendon (a) 23, so that the present invention is applied. The cutting was performed by separating into two steps of cutting by the skew cutter 16 and two-stage cutting by the horizontal cutter 17. That is, as shown in FIGS. 4A and 4B, the skew cutter 16 cuts the entire tendon (a) 23 and only a part (2/3) of the tendon (b) 24. The cutting is performed, and then the humeral head 12a of the shoulder joint having weak coupling force is pushed down by the separator 15 in the downward Yb direction, and the horizontal cutter 17 that performs a horizontal sliding cut along the separator 15 includes:
The remaining portion of the tendon (b) was cut horizontally to make a second-stage cut. Since the cutting in the second stage employs horizontal cutting, the cutting edge of the cutter abuts against the bone before stopping the nearby meat 25 to stop cutting. Thus, according to the breast fillet separation method of the present invention, it is possible to automatically cope with a change in the size of the work and to perform the creasing of the shoulder joint without damaging the meat portion, and the wings to be performed subsequently At the same time, the breast can be separated under a high yield by a peeling mechanism for peeling the breast.
