[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a breast meat for meat carcass upper body (hereinafter referred to as "kabuto"), in which muscles near shoulder joints are separated to peel off breasts together with wings from said kabuto, and to remove meat under armpits and to remove meat. The present invention relates to a separation method and an apparatus therefor.
[0002]
[Prior art]
Recently, extensive breeding, slaughtering, and carcass processing 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]
[Problems to be solved by the invention]
By the way, although stripped of breast meat than Kabuto is the upper body after you disconnect the thigh meat of meat for chicken also conventional has been carried out by hand, remaining between the breast meat and clavicle that were disconnected, said the fillet There is a problem that the product is likely to be scratched during the stripping operation, thereby lowering the commercial value. Further, it is necessary for an operator to directly touch the meat while touching the meat, and there is a problem in that the management cost in terms of yield and food hygiene is relatively high.
As shown in the perspective views shown in FIGS. 8 and 9, the breast 10a has an ideal cut surface 35 (streak) formed in a hollow shape around the shoulder joint 11, and the muscle of the body 10b is a humerus. 12b, while the breast 10a is connected to the shoulder joint 11 via the pectoral muscle and the wings 12 are also connected to the shoulder joint 11 via the upper arm muscle, and the breast 10a is connected to the scapula 11a, the upper part of the ostium 11 and the collarbone 14 Is formed between.

It is a figure which shows the situation which presses a humeral head.
[0034]
As shown in FIGS. 1 and 2, the breast meat separating method of the present invention is performed by the following steps. That is,
1. A frustoconical cone 20 for fixing is inserted into a hollow portion 10c of a beetle 10 which is the upper body of chicken meat, and in particular, a joint fossa 11b of a scapula 11a having a clavicle 14 and an ostium 13 at its upper part and the joint The shoulder joint 11 consisting of the humeral head 12a fitted into the fossa is positioned.
[0035]
2. Then, the ulna 12c and the humerus 12b are pulled toward the cone 20, and the humeral head 12a is separated from the joint fossa 11b of the scapula 11a located above the shoulder joint 11.
In addition, the action of the repulsive force is such that a gap is formed between the glenoid 11b of the scapula 11a and the humeral head 12a, a ligament connecting the two, cutting of the membrane, and a breast region connected to the joint site of the scapula. The point of action is, of course, the glenoid fossa 11b of the scapula 11a, but the direction of action should not be limited to one direction, and the cutting point is not limited to one. It is appropriately changed according to a certain membrane, ligament, tendon, or other biological tissue and procedure.
Further, the repelling force may be applied directly to the humeral head 12a, or may be applied via the humerus 12b to the ulna 12c.
[0036]
3, then 1, as shown in FIG. 2, the meat separator 15 is lowered downward c from a somewhat its position by the action of the repelling force, and pressed downward into contact with the top of the humeral head 12a Then, the joint 11c of the scapula 11a is lifted upward.
At this time, the clavicle 14 is pressed by the meat separator 15 so as not to cause a fracture.
4. Next, the cutter blade 16 cuts the entire shoulder 11a of the raised scapula 11a to reach the bone around the joint 11c, and cuts the joint capsule to expose the joint 11c.
[See FIG. 3 (A)]
The meat separator 15 is positioned at a in the figure, and the cutter blade 16 performs the cutting while rotating around the joint 11c of the scapula 11a.
[0037]
5. Then, the humeral head 12a is pushed down by the meat separator 15 so as not to press the exposed joint 11c of the scapula 11a, so that the space between the articular fossa 11b of the joint 11c and the humeral head 12a is greatly widened.
[See FIG. 3 (B)]
6. Next, a cutter blade 16 is inserted between the joint 11c of the scapula 11a and the humeral head 12a, which are expanded, to cut a living tissue such as a ligament.
[See FIG. 3 (B)]
At this time, the meat is protruded from the meat separator 15 which has been pushed down, and as a result, a cut is made in the meat portion, thereby causing damage. However, the meat separator 15 has a structure that does not cause such a problem.
[0038]
7. Then, the operations of the above paragraphs 5 and 6 are repeated, and the meat separator 15 is pushed down the humeral head 12a to the positions of a to c in FIG. 1 to thereby remove all muscles between the joint 11c of the scapula 11a and the humeral head. Disconnect.
[See FIGS. 1 and 3 (C)]
8. Next, the humerus 12b and the ulna 12c are pulled toward the cone 20, and the breast 10a is peeled off from the upper body, the beetle, and separated.
At this time, as shown in FIG. 4, if the hatched portion 14 a on the upper surface of the collarbone 14, which is the other portion except the peripheral portion of the shoulder joint 11, is made, the peeling can be performed more smoothly. .
As shown in the front perspective view of FIG. 3A and the side perspective view of FIG. 3B, the crevice of the clavicle upper surface portion 14a is formed by rotating the round blade cutter 36 into a substantially V-shaped right and left. As shown in FIG. 4B, the circular blade cuts the surface of the collarbone from the base of the shoulder of the collarbone 14 to the portion where the left and right collarbones are fitted, as shown in FIG. D is moved to make a crease over the width C.
In this case, at the time of deboning of the breast, which is the peeling of the breast, the remaining meat at the collarbone can be reduced and the yield can be improved.
[0039]
FIG. 5 is an example of a block diagram showing a schematic configuration of a breast meat separating apparatus of the present invention.
The repetition control circuit 22 is composed of a pressing operation circuit 27, a cutter operation circuit 28, and a repetition timer circuit 29.
That is, the positioning and pressing mechanism 21 detects the pressing position of the meat separator 15 to perform positioning, then presses the positioned meat separator 15 and operates the cutter 16 after pressing. The operation of the cutter is repeated.
The positioning and pressing mechanism 21 includes an XY table with sensor 23, a pressing actuator 24, a vibrator 25, and a meat separator 15 with a oscillating mechanism 26. The position where the attached meat separator 15 can be fitted to the joint 11c of the scapula 11a, which is the shoulder joint 11, is detected. After the positioning, the pressing actuator 24 can press the humeral head 12a.
As shown in FIG. 6, the meat separator 15 has a swing mechanism at its base as a swing type, and can appropriately press an inclined surface. In addition, the vibrator 25 applies vibration to the meat separator 15 at an appropriate frequency so that a plurality of spikes 30 and a front edge 31 provided on the back surface of the separator, which will be described later, bite into the humeral head which is a pressing surface.
[0040]
As described above, the meat separator 15 is a plate-like material having a substantially 8-shaped notch 32 as shown in FIG. 7A, and the side surface 33 of the notch 32 is tapered, as shown in FIG. As shown, the fitting of the scapula to the joint 11c is ensured, and the position can be easily detected.
As shown in FIG. 2A, a plurality of edges 31 and spikes 30 are provided on the back surface of the distal end so that the humeral head 12a can be reliably pressed.
[0041]
The cutter blade 16 is made of, for example, a small-diameter horizontal rotating blade, and slides as appropriate using the meat separator 15 as a guide to enable cutting from any direction, and ligaments, tendons, muscles, membranes, and skin around the shoulder joint. Etc. can be cut.
[0042]
【The invention's effect】
With the above configuration, the breast meat can be easily peeled off without damaging the meat portion from the chicken beetle for meat, and the yield can be improved.
