Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention involves making vertical incisions in both inner thighs of a poultry carcass that has been dehaired and hollowed out in the process of processing poultry carcasses. The present invention relates to a disassembly method and a disassembly device for removing both joints of the pelvis and both femurs of a poultry carcass.

[Conventional technology]

Generally, in the process of dissecting a poultry carcass that has been dehaired and hollowed out, vertical incisions are first made in both inner thighs of the poultry carcass, and then the pelvis and both thighs of the poultry carcass are cut. Both joints with the bone are removed.

Conventionally, the above-mentioned scoring work involves suspending a dehaired and hollowed poultry carcass by its neck from a moving shackle suspended on an overhead conveyor, etc. uses a cutter knife or the like to make vertical incisions on both inner thighs of poultry carcasses, but this incision work must be done in an unstable state where the poultry is suspended and swings. Because of this, the work requires skill and requires a great deal of labor from the workers.

Furthermore, in the joint disassembly work that is performed subsequent to the incision work, conventionally, a worker removes the left and right thighs of the poultry carcass that has been incised and is suspended from the shaft. Grasp it with your hands, place your fingers on the joint of the groin from behind, and simultaneously move the left and right crotches from the ventral side to the dorsal side in a double-fold shape.
The joints are removed by turning them 180 degrees, but this work must be done while suspended and swinging in an unstable state, which requires skill and requires a lot of labor on the part of the workers. has become enormous.

[Problem that the invention seeks to solve]

In order to mechanize or automate the incision work and the joint removal work, various devices have been prototyped in the past, but the growth rate of poultry varies depending on individual differences in nature and breeding conditions of the producer. Due to variations in bone structure, meat content, etc., it is difficult for the various devices that have been prototyped in the past to reliably support the poultry carcass suspended from the shackle during the scoring work, and it is difficult to ensure proper accuracy. Not only is it not possible to make efficient incisions, but the meat may also be cut into. In addition, when removing the joints, the left and right sides of the poultry carcass suspended from the shackle must be removed. It is difficult to grasp the crotch reliably, and when rotating the left and right crotches at the same time in a double-folded position, the crotches may slip out or come off from the gripping member, and the femur may break. Not only is it not possible to perform this work reliably and efficiently, but it may also damage the poultry carcass. Therefore, it is unavoidable that the above-mentioned scoring work and the above-mentioned At present, the disarticulation process is not mechanized or automated at all, and this is a major bottleneck in the process of processing poultry carcasses.

In view of the above-mentioned problems, the present invention enables appropriate and efficient scoring work to be performed without damaging poultry carcasses, regardless of the growth level of the poultry. This system enables the joint removal work that follows the scoring work to be carried out reliably and efficiently, and at the same time aims to smooth and speed up the entire processing process for poultry carcasses, as well as to simplify its configuration. It is ivy.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention first provides a method in which a poultry carcass that has been dehaired and hollowed out is disarticulated between the pelvis and the femur during the movement of the poultry carcass. The poultry carcass suspended from the shuttle is supported at the center of the moving device in the running direction, the supported poultry carcass is held on its back on the moving device, and the held poultry carcass is Incisions are made in both inner thighs of the poultry carcass using a pair of cutters, and both of the incised legs are pressed downwards on the moving device, and this pressure connects both the pelvis and both femurs. It is designed so that each can be removed.

Next, the means of the apparatus of the present invention includes a shackle that is suspended on an overhead conveyor and travels and moves the poultry carcass by hanging the neck of the poultry carcass; A poultry carcass hung on the shackle, which travels in the same direction and at the same speed as the shackle below the line, and has an inclination angle that rises from the starting end to the terminating end in the traveling direction; a moving device that supports the dorsal side of the moving device and moves the moving device; The movable device is symmetrical and substantially parallel to the center of the traveling direction with an appropriate interval, and has an inclination angle that is a gentler upward slope than the inclination angle of the moving device, and further toward the rear end. The shaft is arranged so that the distance from the moving device gradually narrows, and supports both wings of a poultry carcass hung on the shackle from below, and also supports both wings of the poultry carcass as the poultry carcass travels. a pair of first guides that respectively press the thighs from above; and a pair of first guides that are provided near the starting end of the moving device and that come into contact with the lower part of the poultry carcass hung on the shackle, so that the shackle is attached to the poultry carcass. a second guide that changes the poultry carcass from a suspended upright state to a supine state by applying a contact friction force that resists the traction force of the second guide; , a pair of cutters that respectively abut from above on both inner thighs of the poultry carcass held by the moving device and the first guide to make incisions as the poultry carcass moves; The terminal end portions of the first guides are connected to the rear end portions of the first guides, and are arranged symmetrically and substantially parallel to each other with an appropriate interval with respect to the center of the moving direction of the moving device. It has a downwardly sloping shape, and contacts both legs of the poultry carcass from above, and as the poultry carcass moves, it presses both legs downward, thereby damaging the pelvis and both femurs. and a pair of joint removal guides for removing both joints.

[Effect]

In this invention, a poultry carcass that has been dehaired and hollowed is hung on a shaft in an upright position, facing the direction of travel of the shaft and hanging backwards, and when it reaches the entrance of the disassembly device. , first, both wings contact the first guide, and are centered approximately at the center in the running direction,
The vehicle will be guided by the first guide. On the other hand, the lower part of the poultry carcass comes into contact with the second guide before reaching the starting end of the moving device, and the traveling speed of the lower part slows down due to the frictional force of the contact, and the poultry carcass is moved onto the second guide. The patient will be in a supine position. Further, at this time, the poultry carcass is centered on the center line in the traveling direction of the moving device by the second guide.

Next, the poultry carcass that has passed through the second guide runs on the moving device in a supine state with its neck hung on the shackle and its back side supported by the moving device, and as it moves, The inclination angle, which is an upward slope toward the traveling direction of the moving device, promotes the supine state of the poultry carcass. The poultry carcass, which has been traveling in an almost completely supine state, is reliably held between the first guide and the moving device due to the narrowing of the distance between the first guide and the moving device. The guides bite into both inner thighs, and both inner thighs become tense.

Next, the poultry carcass that has been moving with both inner thighs in a state of tension is cut by a pair of cutters that contact both inner thighs from above. Each is incised.

Next, the poultry carcass, which has had its inner thighs incised, is supported on a moving device as it travels by a pair of joint release guides that abut each of its legs from above. Using the lumbar region of the patient as a fulcrum, both legs are pushed downward, and the joints of the pelvis and femurs are disengaged.

Then, as the poultry carcass has both joints removed, it is released from the support of the moving device as it moves, leaves the dismantling device suspended from the shackle, and moves on to the next processing step. being carried away.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described in detail based on the drawings.

In the poultry carcass processing process, the poultry carcass A, which has already been dehaired and hollowed out, is suspended from a shackle 1 which is suspended from an overhead conveyor (not shown) and travels. , its neck Aa is hung on the lower end of the shuttlecock 1 so that it faces backward in the running direction of the shuttlecock 1, and the shuttlecock runs backwards.

Below the running line of the shackle 1 is a moving device 2 that maintains an appropriate distance from the lower end of the shackle 1 and supports the dorsal side Ab of the poultry carcass A.
is provided. This moving device 2 is configured to travel in the same direction on the same line as the traveling line of the shaft 1 and at the same speed as the traveling speed of the shaft 1. 3, and is comprised of an endless chain conveyor 6 suspended from a drive wheel 4 rotatably mounted on a frame F and a driven wheel 5 rotatably mounted on the frame F. The chain conveyor 6 is approximately parallel to the running direction, and the drive wheels 4 are arranged at suitable intervals so that the chain conveyor 6 gradually narrows a little toward the terminal end 6b.
and a driven wheel 5 in two parallel rows, and are each provided with a large number of freely rotatable rollers 7, 7, . . . that come into contact with the dorsal side Ab of the poultry carcass. Furthermore, both chain conveyors 6 each have an inclination angle that is an upward slope from a starting end 6a in the running direction that is hung on the drive wheel 4 to a terminal end 6b in the running direction that is hung on the driven wheel 5. In this embodiment, both chain conveyors 6 are suspended around a small-diameter drive wheel 4 and a large-diameter driven wheel 5, respectively.
An appropriate inclination angle is provided by the difference in the diameter of both wheels 4 and 5, and this inclination angle is adjusted to the size of the poultry carcass A by an inclination angle adjustment wheel 8 provided close to the drive wheel 4. It can be adjusted accordingly.

A first guide 9 is provided above and relatively close to both the chain conveyors 6, and extends from in front of the starting ends 6a of both the chain conveyors 6 to near the terminal ends 6b thereof. The first guides 9 are arranged at appropriate intervals in the left-right direction with respect to the center of the running direction of both the chain conveyors 6, and are arranged symmetrically and substantially parallel to the outside of each of the two chain conveyors 6. ,
Both chain conveyors 6 are arranged at an inclination angle that is a gentler ascending slope than the inclination angles of the chain conveyors 6. As a result, both the first guides 9 move toward the terminal ends 6b of the chain conveyors 6 as they reach their terminal ends 9c.
The distance between the chain conveyor 6 and the chain conveyor 6 in the vertical direction gradually narrows as the distance approaches the chain conveyor 6. Therefore, each of the first guides 9, at each end 9a, can hold both wings of the poultry carcass A in an upright state suspended from the shaft 1.
They abut Ac from below and support both wings Ac from below to center the poultry carcass A at approximately the center in its running direction. and,
As poultry carcass A moves, both thighs
Ad is pressed from above, the poultry carcass A is held between the two chain conveyors 6, and the poultry carcass A is bitten into both inner thighs Ah of the poultry carcass A.
Both inner thighs Ah are tense. It should be noted that the respective tip ends 9a of both first guides 9 are slightly symmetrically widened toward the front in order to center the poultry carcass A approximately at the center in the traveling direction.

A poultry carcass A, which has been traveling while being suspended from the shackle 1, is placed below each tip 9a of both first guides 9, and its wings Ac are placed below each tip 9a of both first guides 9. Waist guides 10 are arranged to guide the poultry carcass A by abutting the waist Ae from both sides in the running direction before abutting the poultry carcass A, respectively. This waist guide 10
are arranged at appropriate intervals in the left-right direction with respect to the center of the running direction of both the chain conveyors 6, and are arranged symmetrically and substantially parallel to each other on the outside of both the first guides 9, and both ends thereof Part 10a
protrudes appropriately to the front of each tip end 9a of both first guides 9, and spreads out symmetrically toward the front. The waist guides 10 extend horizontally at approximately the same height as the starting ends 6a of the chain conveyors 6. As a result, the poultry carcass A reaches both first guides 9 in a somewhat centered state.

Both first guides 9 and waist guide 10
is suspended from the shackle 1,
In addition, side guides 11 are disposed that contact both flanks Af of the poultry carcass A that has been traveling guided by the first guides 9 from both sides in the traveling direction, and guide the poultry carcass A. . The side guides 11 are arranged at appropriate intervals in the left-right direction with respect to the center of both chain conveyors 6 in the running direction.
and are arranged symmetrically inside each tip 9a of both first guides 9, and each tip 11a thereof is arranged symmetrically inside each tip 9a of both first guides 9.
are respectively connected to the waist guides 10.
These extend to the rear end portions 10c of each. Each of the side guides 11 is inclined so as to gradually become downward toward its respective rear end portion 11b, and is slightly narrowed symmetrically in a tapering shape. As a result, the poultry carcass A travels within the first guides 9 in a further centered state.

The front end portions 6a of both chain conveyors 6 constituting the moving device 2 are in contact with the lower part of the poultry carcass A hung on the shackle 1, so that the traction force of the shackle 1 is applied to the poultry carcass A. A second guide 12 is provided to change the poultry carcass A from a suspended upright state to a supine state by applying a contact friction force against the second guide 12. This second guide 12 is a leg guide 1 that opens both legs Ag of the poultry carcass A hung on the shaft 1 to the left and right in the running direction.
3 and the poultry carcass A to both chain conveyors 6.
, and apply a contact friction force to the waist Ae of the poultry carcass A that resists the traction force of the shaft 1 to turn the poultry carcass A from a sitting state to a supine state. centering guide 14.

The leg guide 13 is disposed below both the waist guides 10 and extends from near the intermediate portion 10b of both the waist guides 10 to near the rear end portion 10c of both the waist guides 10.
This leg guide 13 is arranged on the center line of both chain conveyors 6 in the running direction, has an appropriate width on the left side in the running direction, and is formed in a shape that widens toward the rear end 13b. The width in the left-right direction is approximately the same as the width in the left-right direction of each rear end portion 11b of the both side guides 11. The leg guide 13 also has a rear end portion 13b such that the rear end portion 13b is located at approximately the same height as each rear end portion 10c of both waist guides 10.
It slopes upward as it goes to 3b. The tip end 13a of the leg guide 13 is made of a U-shaped rod member in order to make it easier to open both legs Ag of the poultry carcass A to the left and right in the running direction. ing. As a result, the poultry carcass A reliably opens both legs Ag to the left and right in the running direction, and travels within the first guides 9 while seated on the leg guides 13, and at the same time Centering of carcass A is further promoted. At this time, due to the frictional force caused by the contact between both legs Ag and the leg guide 13, both legs Ag
The running speed is slightly slower.

The centering guide 14 has its tip 1
4a is connected to the rear end 13b of the leg guide 13, and the starting end 6a of both chain conveyors 6
It extends above. This centering guide 14 is arranged at an appropriate interval in the left-right direction with respect to the center of both chain conveyors 6 in the running direction.
They are arranged symmetrically inside each of the first guides 9, and their respective rear end portions 14c are slightly symmetrically widened toward the end, and the width in the left-right direction is equal to that of the first guides 9. The width is approximately the same as the width of the guide 9 in the left and right direction. Further, these centering guides 14 are arranged as they move toward their respective rear ends 14c so that their respective rear ends 14c are located at approximately the same height position as the starting ends 6a of both chain conveyors 6. Each slope has an upward slope. Both centering guides 14 have a substantially linear intermediate portion 14b so as to support the waist Ae of the poultry carcass A hung on the shaft 1 from below.
and upwardly curved curved portions 14d, and each of the curved portions 14d is inclined outward in each extending direction of both centering guides 14. As a result, as the poultry carcass A travels, its waist Ae comes into contact with each of the intermediate parts 14b and each curved part 14d in such a way that it is held from below, and this contact causes the two chain conveyors to 6 is reliably centered on the center line in the running direction. The running speed of the waist Ae is slowed down due to the frictional force caused by this contact of the waist Ae, but since the shaft 1 is running at a predetermined speed, the neck Aa of the poultry carcass A is in the lead. The waist part Ae is delayed, and while traveling on both centering guides 14, the poultry carcass A is suspended from the shaft 1 and gradually changes from an upright seated state to a supine state.
When the patient passes both centering guides 14, he or she is in an almost completely supine state. That is, both centering guides 14 apply contact friction force that resists the traction force of the shaft 1 to the waist of the poultry carcass A.
It is configured to give to Ae. As a result,
The poultry carcass A is centered on the center line of both chain conveyors 6 in the running direction, and placed on both chain conveyors 6 in a supine state with its dorsal side Ab in contact with each roller 7 of both chain conveyors 6. In this state, the vehicle is moved by the shaft 1 and both chain conveyors 6.

In the vicinity of the rear end portions 9c of both first guides 9, both legs Ag of the poultry carcass A that has been traveling in a supine state are supported from below.
A pair of third guides 15 are provided for lifting the poultry carcass A upward to place the poultry carcass A in a substantially completely supine state. Both third guides 15 are disposed between both chain conveyors 6 and both first guides 9, and have substantially the same inclination angle as the inclination angle of both first guides 9. It is arranged substantially parallel to the rear end portion 9c of the first guide 9 in the vertical direction, and extends over an appropriate length along the direction in which both the first guides 9 extend.
Further, the third guides 15 are arranged at appropriate intervals in the left-right direction with respect to the center of the running direction of the chain conveyors 6, and are arranged symmetrically on the outside of each of the first guides 9. The rear end portions 15b of each of the rear end portions 15b are symmetrically expanded toward the end. As a result, the poultry carcass A is held in a supine position by both the chain conveyors 6 and the first guides 9.
, both of its legs Ag are lifted upwards and placed in an almost completely supine state, and the swinging of both legs Ag in the vertical direction is prevented, and the muscle insertion operation to both inner thighs Ah, which will be described later, is performed. I will definitely do it.

Each rear end portion 14 of both centering guides 14
c and each of the tips 15a of both the third guides 15, there are a pair of second guides for supporting both legs Ag of the poultry carcass A running on both the chain conveyors 6 in a supine state from below. Four guides 16 are provided. This fourth guide 16 has each tip end 16a connected to each rear end 14c of both centering guides 14, and
Each rear end portion 16b is connected to each tip end portion 15a of both third guides 15, and is symmetrical with respect to the center of both chain conveyors 6 in the running direction. Furthermore, since both of the fourth guides 16 are connected to both of the centering guides 14 and both of the third guides 15, they gradually connect to both of the first guides 9 as they reach their respective rear ends 16b. It has an inclination angle approaching . As a result, the poultry carcass A running on both chain conveyors 6 in a supine state is promoted to the supine state as it travels, and
Both legs Ag are prevented from swinging in the vertical direction,
Both chain conveyors 6 travel reliably while being centered on the center line in the running direction.

The respective rear ends 9c of both the first guides 9 are incised at the inner thighs Ah of the poultry carcass A which is held between the two chain conveyors 6 and the first guides 9 in a supine state. A pair of cutters 17 are provided. Both cutters 17
The above two contact each of the inner thighs Ah of the poultry carcass A, which has been traveling in a supine state, from above, and make incisions as the poultry carcass A travels. At each rear end portion 9c of the guide 9, a pair of cutter holders 18 are respectively attached to the upper portions of the first guides 9.

First, the cutter 17 will be explained.
As shown in FIG. 5, this cutter 17 is female-shaped, and has a cutting edge portion 17a that contacts the inner thigh Ah of the poultry carcass A from above and is appropriately bent downward. is bolt hole 1 for attaching to cutter holder 18 with bolt 19
7c is provided.

Next, as shown in FIGS. 6 to 8, the cutter holder 18 is formed relatively long in its longitudinal direction and has an appropriate width in its vertical direction. This cutter holder 18 is
Inside the longitudinal center portion 18a (i.e.
As will be described later, when the cutter holders 18 are fixed to the first guides 9, the inner side of the first guides 9 has a longitudinal axis 17b of the cutter 17. A recess 18b that loosely engages with the side portion of the recess 18b is formed relatively long in the longitudinal direction. A long hole 18c is formed which extends appropriately in the longitudinal direction. The vertical width of this elongated hole 18c is formed to be slightly larger than the diameter of the shaft portion of the bolt 19, so that when the bolt 19 and the bolt hole 17c of the cutter 17 are loosened, the bolt 19. Therefore, the cutter 17 is movable in the longitudinal direction of the cutter holder 18 along this elongated hole 18c. According to the size of the poultry carcass A, the cutting edge portion 17a is attached to the inner thigh portion Ah of the poultry carcass A.
This is to adjust the position of contact from above.

Here, to explain how the cutter holder 18 to which the cutter 17 is attached is fixed to both the first guides 9, the cutter holder 1
8 is fixed to the upper part of both first guides 9 by welding or the like in the same direction as each of the first guides 9, as shown in FIG.
Both first guides 9 are fixed to each other so as to be inclined outward in each extending direction. Therefore,
The cutters 17 respectively attached to the cutter holders 18 have their respective cutting edges 17a in a supine state and follow the travel path of both inner thighs Ah of the poultry carcass A that has been traveling on the both chain conveyors 6. Each protrudes upward and abuts on both inner thighs Ah from above, respectively, and as the poultry carcass A moves, incisions are simultaneously made in both inner thighs Ah.

Note that, as described above, both cutter holders 18 have appropriate widths in the vertical direction, so that the two cutter holders 18 touch each of the first guides 9 until reaching the fixed portions of both cutter holders 18. The wings Ac of the poultry carcass A that were in contact with each other will come into contact with the upper parts of both the cutter holders 18 after the fixed parts of the cutter holders 18, respectively,
When making incisions on both inner thighs Ah, both wings Ac
is not a hindrance. That is, the two cutter holders 18 not only are attached to the two cutters 17, but also have the function of guiding both chicken wings Ac so as not to interfere with the creasing operation.

At the terminal end portions 6b of both the chain conveyors 6 constituting the moving device 2, both leg portions of the poultry carcass A are respectively incised on both inner thigh portions Ah.
A pair of plates that contact Ag from above, press both legs Ag downward as poultry carcass A moves, and release the joints between the pelvis and both femurs of poultry carcass A. A disarticulation guide 20 is provided. Both joint release guides 20 are connected to the rear end portions 9c of both the first guides 9, and are symmetrically arranged at appropriate intervals in the left and right direction with respect to the center of the running direction of both the chain conveyors 6. They are arranged almost parallel. Further, this joint release guide 20 is connected to both chain conveyors 6.
It has a shape that slopes downward in the direction of travel, and in this embodiment,
A round bar-shaped upper guide 20 that is substantially parallel to the center of the running direction of both chain conveyors 6 and has a relatively gentle downward slope.
a, and a round bar-shaped lower guide 20b that widens toward the end in the running direction of both chain conveyors 6 and has a steeper slope than the upper guide 20a. It has a structure in which the comrades and the respective rear end parts are connected to each other. This is because when the leg Ag of the poultry carcass A is pressed with a single round rod-shaped guide, the pressing force is concentrated on the one point where it came into contact, and the contact area is delayed before the pelvis and femur disengage. This is because the bones of the legs Ag would break, and by pressing with the upper guide 20a and the lower guide 20b, the bones of the legs Ag are prevented from breaking. As a result, the poultry carcass A, which has been incised on both inner thighs Ah, is
As it travels, the upper guide 20a and the lower guide 20b come into contact with the legs Ag from above, and due to the downward slope of the guides 20a and 20b, the legs Ag are placed on the chain conveyor 6. The supported lumbar region Ae is used as a fulcrum to push downward, and both the pelvis and femur joints disengage at the same time.

Note that, as in the embodiment, the joint release guide 20 does not necessarily include both guides 20a and 20b.
It is not necessary to configure the leg with
It may be of any configuration as long as it does not break the bones of the Ag, and for example, it may be a plate-shaped guide member having an appropriate width and length.

Further, at the terminal ends 6b of both the chain conveyors 6 constituting the moving device 2, poultry carcasses A
A fifth guide 21 is provided to prevent the legs Ag from being caught up in both chain conveyors 6 during and after the disarticulation of the legs Ag. This fifth guide 21 is arranged at an appropriate interval in the left-right direction with respect to the center of the traveling direction of both the chain conveyors 6, and inside each of the joint removal guides 20, and is arranged between the respective chain conveyors 6. They are arranged symmetrically and almost parallel to each other slightly outward. Further, each of the fifth guides 21 is curved downward with an arc approximately the same as the radius of curvature of the driven wheel 5 from each intermediate portion 21a to each rear end portion 21b, and Each of the curved rear end portions 21b gradually widens toward the rear in a laterally symmetrical manner. As a result, poultry carcass A is
During and after the disassembly of the joints, both legs Ag will not be caught up in the chain conveyors 6, and both joints will be reliably disengaged, and the joints will run smoothly after the joints have been disengaged. be moved.

Next, the specific operation of the above configuration will be explained in detail using FIG. 10.

First, depending on the size of the poultry carcasses A (normally, poultry carcasses A from the same producer are processed together, the poultry carcasses A have a somewhat average size). ), the inclination angle adjustment wheels 8 are adjusted in advance to set the inclination angles of both chain conveyors 6, and the blade tips 17a of both cutters 17 are inserted into both inner thighs Ah of the poultry carcass A from above. The positions at which they abut each other are also adjusted in advance.

The poultry carcass A, which has been suspended from the shuttle 1 and is traveling backwards, is placed at the entrance
When the poultry carcass A reaches both first guides 9, its wings Ac are guided to both first guides 9 while being centered to some extent in the center of the running direction. They are each supported from below by the first guides 9, and the upper part of the poultry carcass A is centered at the center in the running direction.

Next, the poultry carcass A, which is traveling with both wings Ac supported by both first guides 9, has both flanks Af guided by both side guides 11, and both legs Ag are guided by leg guides. 13 to open left and right in the running direction, and the poultry carcass A is seated on the leg guides 13. As a result, the lower part of the poultry carcass A is also centered at the center in the running direction (see FIG. 10A).

Next, the poultry carcass A, which is traveling while seated on the leg guides 13, is placed on both centering guides 1
4, and here the waist portion Ae contacts each intermediate portion 14b and each curved portion 14d so as to be held from below. Due to this contact,
The poultry carcass A is reliably centered on the center line of both chain conveyors 6 in the running direction. At the same time, due to the frictional force caused by the contact, the neck Aa of the poultry carcass A leads and the waist Ae lags behind, so that the poultry carcass A gradually changes from an upright sitting position suspended from the shell 1 to a supine position. (See Figure 10B), both centering guides 1
When you pass 4, you will be in an almost completely supine state. Then, the patient rides on both chain conveyors 6 in a supine state with the dorsal side Ab in contact with each roller 7 of both chain conveyors 6.

Next, the poultry carcass A is moved in a supine state by the shaft 1 and both chain conveyors 6.
Since the vertical distance between both chain conveyors 6 and both first guides 9 gradually narrows in the traveling direction, both chain conveyors 6 and both first guides 9 gradually narrow as they travel. The first guides 9 are gradually held in a pinched state, and at the point where they reach the respective rear end portions 9c of both first guides 9, they are firmly held in a pinched state. As a result, both first guides 9
penetrate into both inner thighs Ah of poultry carcass A,
Tense both inner thighs Ah (Figure 10C)
reference). Further, both legs Ag of the poultry carcass A are respectively lifted by both third guides 15, and as the poultry carcass A travels, the whole becomes almost completely supine.

Next, in an almost completely supine position,
In addition, both inner thighs Ah of the poultry carcass A are being tensioned by both first guides 9, and the poultry carcass A is moving. Both cutters 17 are brought into contact with both inner thighs Ah of the poultry carcass A from above. At the same time, incisions are simultaneously made on both inner thighs Ah (see Figure 10D).

Next, the moving poultry carcass A, which has been incised on both inner thighs Ah, reaches both joint removal guides 20 at the rear ends 6b of both chain conveyors 6, and there, the poultry carcass A is moved. Both joint release guides 20 abut on both leg parts Ag from above, and as the legs move, both joint release guides 20 move both leg parts Ag downward with the waist part Ae supported on both chain conveyors 6 as a fulcrum. , and both joints of the pelvis and femur are released at the same time (see Figure 10E).

Then, a poultry carcass A with both joints removed.
As it travels, it is released from the support of both chain conveyors 6 and exits the exit Y of the demolition equipment while being suspended from the shaft 1.
It is transported to the next processing step.

Thereafter, the same operation is repeated to disassemble the poultry carcasses A continuously.

〔Effect of the invention〕

As described above, according to the present invention, while the poultry carcass is running on its back, the incision work and the joint disassembly work are performed continuously, and the poultry carcass is disassembled while the poultry carcass is running and moving. Therefore, regardless of the growth level of the poultry, the slaughtering work can be carried out reliably and efficiently without damaging the poultry carcass. Further, the disassembly work of the poultry carcass can be carried out reliably and efficiently, and manual work is not required, so that the entire process of processing the poultry carcass can be facilitated and speeded up. In addition, the incision work and joint removal work, which were previously done as separate processes, can now be done in one process, dramatically improving the efficiency of the entire poultry carcass processing process. . Furthermore, since the structure is simple, it can be provided at low cost, and is extremely effective in saving labor for this type of work.
