Abstract
Description
[Technical Field]
[0001] The present invention relates to a mechanism for cutting and peeling chicken neck meat (also called small meat) from the neck of a chicken for eating. This is a rare edible part that surrounds the cervical vertebrae of a chicken and can only be obtained in small amounts from a single chicken. It is a valuable part of the chicken that is soft, low in fat, and chewy, and is eaten in dishes such as yakitori. The present invention relates to a mechanism for cutting and peeling chicken neck meat from the chicken's neck (cervical vertebrae), and in particular to a mechanism for cutting and peeling chicken carcasses with the top part attached. [Background technology]
[0002] As devices for removing bones from meat, for example, a chopper that processes meat into mince and is equipped with a bone fragment removal device that removes bone fragments such as cartilage and tendons mixed in with the meat (see Patent Document 1), and a device that has multiple slits to prevent the passage of certain bone fragments and other foreign objects, and removes the bones by scraping off the minced meat that passes through the slits with a scooper (see Patent Document 2).Furthermore, a meat deboning device (see Patent Document 3) has a configuration in which a scapula deboning station, spaced a predetermined distance from the input station, and a humerus deboning station, spaced the same distance from the input station, are arranged in a straight line at equal intervals in that order, with a bone discharge station downstream of the humerus deboning station for discharging the humerus, and the work is transported in a suspended state via a fixed and movable transport path, deboned during the transport process, and the deboned humerus is discharged from the final station (discharge station). Other proposed devices include an automatic bone-in meat deboning device (see Patent Document 4), which uses a suspending part to grasp the exposed neck of the bone-in meat, scores the bone along its length while it is suspended, and then removes the meat from around the bone to debon it.
[0003] Therefore, the inventor has attempted to mechanize the process of cutting and peeling chicken necks, and has proposed various chicken neck peeling mechanisms with a basic configuration that includes a first stage in which a plurality of casings with a base plate with grooves on which the chicken necks can be placed are arranged toward the center of a disc-shaped turntable, and the turntable is rotated horizontally at a constant speed, and when the rotation is stopped, the chicken necks are placed on the base plate; a second stage in which the chicken necks placed on the base plate are pressed from above with a pressure plate to straighten them and are clamped from both sides with a pair of blade clamps; and a third stage in which the chicken necks that have risen further upward due to the clamping by the blades are cut and peeled with a peeling unit (see Patent Documents 5, 6, and 7).
[0004] On the other hand, when removing the clavicle, coracoid, and sternum from the carcass after removing the thighs, breasts, wings, fillets, head, and internal organs, this process is not only time-consuming but also requires skill, as it is done by hand, and is particularly troublesome and time-consuming when processing large quantities of chicken carcasses.
[0005] Therefore, various devices have been proposed that allow even an unskilled person to automatically peel off a large amount of copper continuously with simple operations.
[0006] For example, a device is used in which the neck from a poultry carcass is fixed to a shackle, a peeling rod is placed at the base of the clavicle and coracoid, and the shackle is moved and pressed down by the peeling rod to peel off the cap (see Patent Document 8). This device moves forward by pressing the neck of the body shell with an electrically operated neck-pressing chain, correcting its position with a position correction plate, and then moves toward a fixed piercing rod, which is inserted into a recess in the chest, and as it moves further, the cap is peeled off and separated (see, for example, Patent Documents 9 and 10). The device comprises a first holder that fits into the thoracic cavity of the poultry carcass to hold the poultry carcass and moves in a first predetermined direction, a second holder that has a holder that holds the cervical vertebrae of the poultry carcass and moves in a second predetermined direction, and a guide member that is close to the holder and guides the cervical vertebrae of the poultry carcass in the direction of movement of the holder, and the first holder and the holder of the second holder move apart relative to each other to peel off the top part from the poultry carcass (see, for example, Patent Document 11).

[0008] Normally, when cutting chicken neck meat from chicken bones, the copper part of the chicken bones is separated in advance during the butchering process, either manually or using a copper part separation device as described above. However, when chicken bones with the copper part still attached are used as raw materials, or when a copper part separation device or prior process is not installed at the processing plant, the rib part of the chicken bones has a tunnel-like shape, making it difficult to set them into a conventional chicken neck meat cutting and peeling device.
[0009] In view of the above problems of the prior art, the present invention aims to provide a mechanism for peeling chicken neck meat from chicken bones with the copper parts still attached, which can use chicken bones with the copper parts still attached as a raw material in the work of peeling chicken neck meat, thereby shortening the process, reducing the number of workers, and enabling the peeling of chicken neck meat at low cost. [Means for solving the problem]
[0010] Therefore, the chicken neck meat cutting and peeling mechanism for chicken neck meat from chicken carcasses with caps of the present invention has a first feature in that it is provided with a tunnel insertion rod that can penetrate into the tunnel part of the chicken carcass cap and is supported in the hollow, in which the chicken neck is clamped from both sides with a pair of blades and the raised chicken neck meat is cut by the cutting and peeling part. A second feature is that the tunnel insertion rod is configured to be separable in the length direction according to the chicken neck diameter and body size and to be movable up and down. A third feature is that the tunnel insertion rod is configured from multiple flexible segments. [Effects of the Invention]
[0011] According to the mechanism of the present invention, the equipment or pre-process for separating the copper part at the processing plant can be made labor-saving, and the cost efficiency of the mechanical work of peeling chicken gizzard meat can be improved.

[0013] An embodiment of the present invention will be described below with reference to the drawings. For convenience, like components will be denoted by like reference numerals. The present invention is useful when applied to various chicken fillet peeling mechanisms described in the specifications of Patent Documents 5, 6, and 7, etc. [Example]
[0014] As shown in Figure 1, a typical chicken neck meat cutting and peeling mechanism involves clamping a chicken carcass 1A on both sides with a pair of pointed blades 4a, and cutting and peeling the neck meat, which is the meat part that bulges upward.
[0015] However, as shown in Figure 2, chicken bones 1A used as raw material in conventional devices are originally chicken bones 1A from which the copper part (rib part) 1B attached is separated. If this copper part 1B remains attached, the tunnel part 1C remains, making it difficult to set the bones into the device.
[0016] Therefore, in this embodiment, as shown in Figures 3 to 5, a tunnel insertion rod 2 is provided that can penetrate the tunnel section 1C and is supported in the hollow. The tunnel insertion rod 2 has a U-shaped or V-shaped groove 2a that opens upward in the longitudinal direction and is formed so that the cross-sectional diameter gradually increases from the front to the rear end. This is to provide a height difference that follows the curvature of the chicken's body, i.e., the inner diameter of the tunnel section 1C, and to prevent the neck, which sinks during clamping, from being scraped. It is also to eliminate the problem of the chicken carcass 1A not sinking or having difficulty sinking during clamping.
[0017] The tunnel insertion rod 2 is supported by a pair of shafts 5a via a support plate 4, and is movable up and down by a shaft holding tube 6 and a spring 5 provided between them, and the neck is supported by multiple Y-shaped neck support blocks 3 to prevent it from swinging left and right. [Example]
[0018] As shown in Figures 6 and 7, in another embodiment of the present invention, a tunnel insertion rod 2 is constructed by inserting multiple support bases (segments) 2b of different heights into a rod 2d, and is configured to be separable in the lengthwise direction and movable up and down depending on the chicken's neck diameter and body size. Here, the support bases (segments) 2b are made of synthetic resin or the like, and are formed with U- or V-shaped grooves 2a at the top and through-holes 2c through which the rods 2d pass and fit. Support bases 2b of different heights can be freely combined to create height differences that follow the curvature of the inner diameter of the tunnel section 1C. Incidentally, as shown in Figure 7(b), the desired effect can be achieved simply by providing a groove 2e on a simple rod 2 and inserting support rings (segments) 2b into it. [Example]
[0019] It goes without saying that the same effect as the tunnel section insertion rod 2 can be obtained with a configuration such as a flexible support holder 10, as shown in Figures 8 and 9, in which a C-channel steel holder 7 is fitted with multiple support pieces (split bodies) 8 and springs 9 that bias it upward, giving it flexibility in the vertical direction along its entire length.
