BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breast processor of a carcass processing device (breast meat dismantling device), and more specifically, to a carcass sternum that has been subjected to various pretreatments during the dismantling work of eating birds (broilers, etc.). -A breast processor that can continuously and accurately collect breast, chicken and chicken wings from a dragon bone with good yield.

[0002]

2. Description of the Related Art Conventionally, the dismantling work of edible birds has been carried out by slaughtering, hair removal, hollowing (removal of internal organs) in a processing plant, followed by large disintegration of a cooled carcass, as well as thigh meat, breast meat, chicken and chicken wings. It consists of a dividing process. In the case of hand judgment (manual), the large disintegration in the above process is further applied to processes such as hanging bird, internal thigh muscle insertion, joint removal, dorsal cross knife insertion, spoon insertion, peach removal, wing drop, chicken fillet insertion, chicken fillet removal etc. Separated. The large disintegration process of the above dismantling work has conventionally been performed manually, but the applicant of the present application has developed an automatic processing device capable of efficiently performing this (Japanese Patent Application No. 2-4).
No. 15406, No. 3-15695 and No. 3-1569
No. 6, etc.), and is currently receiving favorable reviews. The carcass that has undergone the pre-process of great disintegration using this method is then
The neck and spine are removed from the keel, and finally the breast meat, chicken and wings are separated and disassembled from the sternum and keel. This dismantling process is conventionally performed manually, but mechanization, particularly automation, is being considered from the viewpoints of labor shortage and efficiency.

[0003]

[Problems to be solved by the invention] However,
Conventional automation requires the carcass to be disassembled to be continuously sent to various processing steps, and at each step disassemble the carcass into specific parts, but the carcass has a complicated shape. However, it is difficult to accurately fix the carcass to the device due to its size variation and softness, and it is possible to accurately align and cut the muscles remaining in the carcass with the fixed cutter. Have difficulty. Therefore, there is a problem that a part of breast meat and chicken fillet remains in the finally-discarded sternum / dragonbone and the collection efficiency of the useful meat portion is low. Therefore, it is an object of the present invention to provide a breast processor capable of performing a disassembling operation of a poultry bird, particularly a breast meat, chicken breast, and a wing removal process quickly and efficiently.

In the device of the present invention, a saddle-shaped bicycle, which is made by molding a saddle from resin, for example, to match the shape of the sternum and keel of the carcass, is built in the previous step.
The carcass with the crotch part (leg), neck and spine removed and the breastbone, keel and chicken breast, chicken and wings attached to its surface remain on the saddle, and By utilizing the hardness of the keel, by fixing the carcass on the saddle , preferably at the center of the sternum, and allowing the fixed carcass to tilt automatically. , It is possible to satisfactorily cut only the tendon that connects the body and the wings without completely separating the body and the wings, and as a result, the breast meat is easily separated from the sternum / carina with the wings. .

[0006]

The invention will now be described in more detail with reference to the preferred embodiments shown in the drawings. The breast processor of the present invention constitutes a part of the latter half of the automatic poultry bird dismantling device, and, following the large disintegration step in the dismantling step, efficiently removes the carcass that has undergone large disintegration from the breast meat and wings. And a breast processor device that is disassembled into chicken breasts. FIG. 1 is a front view of a breast processor of the present invention, and FIG. 2 is a plan view thereof. The breast processor of this embodiment is
A main frame that supports the entire apparatus and is slightly higher than the worker's waist, and a conveyor that circulates around the main frame,
A drive source (motor) for driving the conveyer, a saddle fixed to the conveyer at a constant interval and moving together with the conveyer, a breast peeling unit fixed to the main frame, a chicken fillet insertion portion, a chicken fillet peeling portion, and a sternum. It consists of a dragonbone drop part.

[0007] First, the carcass is hung on the saddle on the conveyor moving at an appropriate speed one by one in a supine manner (the chest is directed upward). The saddle constitutes one important feature of the present invention, details of which are detailed in FIGS. 3-7. FIG. 3 shows a side surface of the carcass when it is hung on a saddle. The saddle is provided with a sternum / dragonbone stopper at the upper left part of the figure (front part in the traveling direction of the conveyor). The top of the sternum is inserted with a recess of the sternum with the tip of the sternum, that is, the neck and spine removed, to prevent the carcass from slipping forward. Furthermore, a lock pin that moves up and down through the saddle presses the center of the sternum against the stopper from below, fixing the sternum and the keel bone and completely preventing movement of the carcass. FIG. 4 shows a plane in which the carcass is fixed to the saddle by the sternum, and approximately the center of the sternum of the carcass is clamped and fixed by the stopper and the lock pin, and wings are extended on both sides thereof.

FIG. 5 is a view for explaining the vertical movement of the lock pin for fixing the carcass, and the lock pin passing through the center of the saddle is always pulled downward by the spring. A guide pin is provided in contact with the lower surface of the guide cam that is fixed to the main frame and bent vertically and horizontally.
The guide pin supports the lower end of the lock pin by the hinge pin, and when the guide pin is guided by the guide cam about the hinge pin and guided to the position of the chain double-dashed line, the right end of the guide pin is curved. Since the hinge pin is eccentric, the tip of the curved guide pin pushes up the lock pin against the force of the spring, and the pushed up tip of the lock pin pushes up the sternum and keel from below, and the sternum and keel stopper To fix the sternum and keel. As a result of fixing the hardest sternum and keel bone in the carcass, the whole carcass is firmly fixed to the saddle.
The guide cam returns to its original state before or on the sternum / carina transportation conveyor shown in FIG. 1, so that the lock pin is lowered to release the sternum / carina fixation, and the sternum / carina is Dropped onto the dragon bone conveyor.

The carcass fixed to the saddle as described above reaches the breast peeling unit, and as shown in FIGS. 6 and 8, both wings of the carcass have a pair of left and right spiral wings and a pair of left and right spiral wings. Proceed with being sandwiched between the guides. The pair of spiral rollers advances the carcass at the same speed as the conveyor chain by the power transmitted through the drive shaft, and the pair of spiral rollers rotate in opposite directions, so that both wings are pulled outward. It is designed to proceed in a state. There are three tendons at the connection between the body of the carcass (chest) and the wings (around the shoulder).
And, as shown in Fig. 8, the first round tendon is cut by the first round blade that can be rotated by different motors and adjusted to the front-back, left-right, up-down and arbitrary angles, and by the same second round blade The second tendon is cut, and the same third round blade cuts the last third tendon. This 3
The tendon of the book is outside the shoulder of the carcass, so that when the tendon is cut, the wings will not be cut and separated from the carcass' trunk (If cut, the breast will be cut by the wings in the next step. It cannot be separated from the keel). Therefore, as shown in FIG. 7, the saddle is rotatably fixed to the base fixed to the conveyor chain through the intermediate plate by the hinge pin, is fixed to the intermediate plate, and the cam roller is provided at the tip of the arm. The cam roller is configured such that the saddle tilts forward by a predetermined angle around the hinge pin according to the height of the cam fixed to the main frame side. That is, in FIG. 7, the first tendon cuts the first tendon at the solid line position, the second round blade cuts the second tendon at the two-dot chain line position, and the third tendon is further tilted forward (not shown). The tendon of the second eye is cut, and the flesh of the wings and the breast are kept connected.

In the carcass from which the tendon has been cut as described above, both wings, which were conveyed by the spirol roller and the guide 1 after the third round blade position, are provided at the peeling conveyor and the conveyor at regular intervals. It is captured by the claws and guided by the guide 2 to forcibly move upward. At this time, since the sternum and keel are fixed to the saddle, the breast meat is torn off by the rising wings. The wings that suspend the breast meat are carried by a peeling conveyor, and the blades are inserted at the boundary between the wings and the breast meat by the motor-driven round blade for cutting the chicken wings and breast meat to cut the breast meat from the wings. Then, the breast meat falls on the spot and is carried on the breast meat conveyor (see FIGS. 1 and 2), while the wings are released from the peeling conveyor at the end of the guide 2 and similarly the wing conveyor. (See FIGS. 1 and 2) The paper is dropped and conveyed. On the other hand, the sternum-Ryukotsu of state marked with white meat is still past the breast meat peeling unit to move forward is fixed to the saddle, along with the muscle for white meat peeling is taken by Sasa Mi creasing unit provided in the main Flame A blade is inserted at the boundary between the scissors and the sternum / dragonbone, and the scissors are peeled off by being scratched by the claws at the scissors peeling part just past the drive motor, and then conveyed by the scissors conveyor (see Figs. 1 and 2). To be done. Sternum
The keel is still fixed to the saddle, and is dropped and conveyed on the sternum / keelbone conveyer just before or on the sternum / keel conveyer by releasing the lock pins shown in FIGS. 3 to 5.

[0011]

As described above, according to the present invention, in the device of the present invention, the saddle shape of the bicycle, which is formed in accordance with the shape of the sternum and keel of the carcass by molding the saddle, for example, of resin, In the process, the carcass with built-in, crotch (leg), neck and spine removed, and breast meat, chicken breasts and chicken wings attached to the sternum / dragonbone and its surface remain on the saddle on its back. , And by utilizing the hardness of the sternum and keel
By fixing the carcass on the saddle , and by allowing the fixed carcass to tilt automatically, only the tendon connecting the body and wings without completely cutting and separating the body and wings. It can be cut well, and as a result, the breast meat is easily separated from the sternum and keel along with the wings. Further, by adopting the breast processor of the present invention described above,
In the case of the conventional automatic poultry bird dismantling device, the maximum processing capacity was about 2,000 birds / hour, but the processing capacity could be set to 4,000 birds / hour. Also, the processing capacity could be freely adjusted to the processing factory capacity by adjusting the line speed.
