A slit for guiding the ridge 60 of 9 is formed. The slit 52 is formed substantially tangential to the stripping roller 46.
Next, the function of the apparatus when the poultry body 58 prepared as described above passes through will be described by giving an example. The poultry body 58 to be treated is retained immediately after the support element 4 has passed through the feed zone (not shown) in the upper stroke of the conveyor 1. The poultry body 58 is held with the sternum 59 facing upward and the wing joint 63 forward. Upon arrival at the support element 4, the poultry body 58
Is placed on the saddle portion 5 so that the inside of the sternum plate 61 rides on the saddle portion. The poultry body 58 is then fastened to the fastening part 6
Pressed against. A beak-shaped extension portion projecting rearwardly of the tightening portion is formed on the sternum plate 61 and the sternal crest 60.
Abut on the part. Therefore, the sternum plate is grasped from above through the arc of the wishbone 64. Meanwhile, the support element 4 approaches the turning of the conveyor 1 to the lower stroke 2 and the saddle part 5 of the support element 4 rides on a cam rail (not shown),
The poultry body 58 is then pinched at the pinching points 68.
The securely held and positioned poultry body 58 thus arrives at the area of the first first treatment device 7 (A).
Immediately after passing through the wing joint 63, the tool 8 of the first processing tool 7 is controlled so that the scraping element 11 rides on the remaining ribs or on the outermost part of the sternum plate 61, as shown in FIG. 2A.
The tool 8 is moved into the passageway of the poultry body 58 so that the meat on it separates , causing the meat in those parts to sag by gravity.
The poultry body 58 then arrives at the second treatment tool 12, the treatment portion 13 of which also operates immediately after the wing joint 63 has passed, the scraping element 16 being formed by the first scraping element 11. Through the separated incision and slide along the stapes 62 and then the sternal plate 61 near the ridge 60 of the sternum 59 to lift the meat portion above it (FIG. 2B).
A continuous downstream of the conveyor, a pair of guide rods 19 penetrate into the cut in which the meat has separated, and
2 is guided and held in the saddle part 5 of the support element 4. In this position the poultry body 58 arrives at the third treatment tool 17, the guide rod 20 of which has the pointed end 21a of the poultry bone 6.
Penetrate the flesh above the wing joint 63 adjacent to 2. In doing so, the dislodging portion 21 pushes the separated meat portion toward the region of the stopping means 22, which holds the meat and removes it from the skeleton around the wing joint 63 when the poultry body further advances. (Fig. 2C).
Then, the scraping element 2 of the fourth processing tool 23.
7 is swung into the passage of the poultry body shortly before the arrival of the sternum 59, whereby the separation of the meat part from the sternum plate 61 started in method steps (a) and (b) is carried out by the sternum plate 61 and the sternal crest of the sternum 59. Continue to the area between 60 (FIG. 2D).
Next, enter the passage of the poultry body 58 and enter the sternum 59.
The scraping blade portion 31 of the fifth processing tool 28, which is controlled to re-emerge shortly before the arrival of, raises the meat portion at the wishbone 64. The scraping of the meat is carried out while pressing the wishbone 64 against the sprouting bone 62.
The inner breast portion 67 is connected to the sternum 59.
A that binds skin, holding already in a state of being pulling meat portion around the edge 60 of sternum 59 are hanging down separated
The binding leather that is doing is then cut. Cleavage of this is a knife blade 37 of the sixth processing tool 33 carried by Rukoto move in the path of the conveyor before the poultry body 58 arrives. The conclusion
The synthetic leather is cut when it enters the cutting area of the knife blade 37. When the ridge 60 of the sternum 59 reaches the cutting area, the knife blades 37 are forcibly separated from each other, so that their cutting edges 39.
Slides along the ridge of the sternum 59 while being biased by a spring against the side of the ridge 60. The controlled movement of the knife blade 37 out of the passage of the poultry body 58 takes place some time after the ridge 60 has reached the cutting area (Fig. 2E / F).
In order to release the strong bond of the meat in the front of the sternum 59 and in the region of the crest 60, the stop element 43 of the seventh treatment tool 40 is controlled so that the poultry body 58 can be moved shortly before it arrives.
8 and hold it in that position until some time after the front portion of the ridge 60 of the sternum 59 has passed. As a result, the meat is simply pressed down and the aforementioned bond is broken (Fig. 2G).
Finally, the bond between the skeleton 69 and the rest of the meat is broken by the stripping roller 46. The stripping roller 46 strips off the ridge 60 of the sternum 59 by slightly pulling the entire meat including the main breast 66 and the internal breast 67. This process is performed with the assistance of turning rollers 49 (FIG. 2H).
After this, the clamping hold exerted by the support element 4 is loosened to release the meat away from the skeleton 69.
At the starting point of the entire process, a peeling step can be provided, which can be performed by a peeling device 53 corresponding to that shown in FIG. This is a pair of rollers 5
This can be done by bringing the circumferential surface of 4 into contact with the poultry body 58, whereby the rollers rotate in opposite directions to form a clamping slit together and the skin is pulled into the clamping slit and thereby gripped and pulled.
