Description

Technical Field

[0001] This invention relates to the field of poultry carcass cutting equipment, and more specifically to an automatic poultry carcass cutting device and its cutting method. Background Technology

[0002] Many parts of poultry carcasses need to be processed. For example, the leg products (a combination of drumstick and leg meat) and wing products (a combination of wing root and breast meat) of commonly consumed poultry such as chicken, duck, and goose are sold separately from the main carcass products. The leg products include the drumstick and the leg meat attached to it, and the wing products include the wing root and the breast meat attached to it. However, with the improvement of living standards, consumers demand to buy the drumstick and wing root separately. Therefore, for the processing of drumstick products, it is necessary to further separate the drumstick and leg meat to obtain separate drumsticks. For the processing of wing root products, it is necessary to further separate the wing root and breast meat to obtain separate wing roots.

[0003] Currently, the aforementioned segmentation methods include manual segmentation and equipment segmentation. Manual segmentation involves manually grasping the drumstick or wing root and bringing it close to the chainsaw for segmentation. This method is not only inefficient but also very easy to cut fingers, making it unsafe. Equipment segmentation, for example, involves a drumstick segmentation device with application number CN202123383231.X. This device includes several drumstick mold boxes fixed on a conveyor belt. The drumstick mold boxes are equipped with segmentation grooves, and the blades of the segmentation device are set in the segmentation grooves. In use, the drumsticks are pressed into the drumstick mold boxes one by one, and then the conveyor belt is started to move towards the segmentation device, and the segmentation device is started at the same time to segment. Although this device does not require manual operation, for the segmentation of drumsticks and leg meat, since the leg meat is relatively soft and easily clung to the drumstick, during installation, it is necessary to straighten and separate the drumstick and leg meat parts of each leg one by one, then place them into the drumstick mold box, and adjust the drumstick and leg meat parts to be located on both sides of the segmentation groove before finally segmenting. The installation process is very complicated, and the two parts after being divided will fall to the same position when they are discharged from the conveyor belt. This means that after the division, the two parts need to be manually selected and sorted, which affects work efficiency. In addition, since the size of the drumstick mold box is fixed, the length after being stretched may exceed the length of the drumstick mold box. The drumstick meat is difficult to keep straight in the drumstick mold box, and it will deviate from the dividing blade during the division, resulting in undercutting or overcutting, which affects the division quality. Summary of the Invention

[0004] To address the technical problems existing in the background art, such as the low efficiency and unsafe operation of manual carcass segmentation; the cumbersome installation of existing equipment and the need for manual selection and classification of each part after segmentation, which affects work efficiency; and the limitation of the fixed carcass structure on the installation of carcasses of different specifications, resulting in over-slicing or under-slicing affecting the segmentation quality, the present invention provides an automatic poultry carcass segmentation device and its segmentation method.

[0005] The technical solution of the present invention is as follows:

[0006] An automatic poultry carcass cutting device includes a cutting machine, which includes a support frame and a horizontal conveying unit mounted on it. A cutting unit is provided on one side of the horizontal conveying unit, and a material unloading unit is provided at the end of the horizontal conveying unit. The carcass to be cut can move along the horizontal conveying unit and can complete the cutting work under the action of the cutting unit. Its automated cutting process greatly improves work efficiency compared with manual cutting, while reducing the risk of manual operation.

[0007] Specifically:

[0008] The horizontal conveying unit includes a first drive source and a transmission mechanism driven by it. The transmission mechanism has several clamping members spaced apart, each with a clamping notch on one side. The carcass to be divided can be suspended and fixed to the clamping member through the clamping notch, and can move with the transmission mechanism. The carcass to be divided is fixed within the clamping notch, eliminating the need for straightening during installation. The divided portion hangs below the clamping member under gravity, facilitating subsequent dividing processing. Since the divided portion is suspended without obstruction, it can accommodate the dividing of carcasses of various sizes, and the installation process is simple and easy to operate.

[0009] The segmentation unit includes two guide members spaced apart and a cutting mechanism located on one side of the carcass transport path. The gap between the two guide members coincides with the carcass transport path. The cutting mechanism includes a second drive source and a segmenting blade connected to it. A portion of the vertical projection of the segmenting blade is located within the gap between the two guide members. Based on this design, the carcass to be segmented can adjust its posture under the guidance and compression of the two guide members, preventing the carcass from moving erratically. The portion of the carcass to be segmented within the gap can naturally retract, and since the segmenting blade is located within the gap, the segmentation line can always be located within the gap between the two guide members during subsequent segmentation, thus preventing easy deviation from the segmenting blade during segmentation and improving the cutting quality.

[0010] The segmentation unit also includes a support plate horizontally positioned below the gap between the two guide members. The support plate has a second guide plate inclined downwards and outwards on one side along the carcass transport direction. Below the second guide plate is a discharge slide inclined downwards and outwards from the support frame. The support plate and the second guide plate are used to support the carcass to be segmented during the segmentation process. The discharge slide is used to smoothly discharge the segmented parts of the carcass to be segmented. Below the discharge slide is a first receiving device. The segmented parts of the carcass after segmentation slide from the second guide plate to the discharge slide, and then slide down the discharge slide to the first receiving device for collection.

[0011] Below the unloading unit is a second receiving device, and the unloading unit is configured to push the remaining part of the carcass out of the holding member and fall into the second receiving device; the carcass segments and the remaining part of the carcass after the division can fall into the first receiving device and the second receiving device respectively, reducing the manual sorting and collection steps after the division, saving manpower and improving work efficiency.

[0012] In one preferred embodiment, two sets of symmetrically arranged cutting machines are provided. When these two sets of symmetrically arranged cutting machines are applied to the cutting of duck wings (a combination of duck wing root and duck breast meat), since the skin-on part is more difficult to cut, the following layout can be adopted: the skin-on part of the duck wing is set towards the cutting blade, while the meat part on the opposite side of the skin-on part is set towards the side away from the cutting blade. In this way, when cutting two duck wings on different sides of the duck carcass, the two duck wings on different sides are cut by these two sets of symmetrically arranged cutting machines respectively, so as to ensure that the two duck wings on different sides can be effectively cut.

[0013] Furthermore, the transmission mechanism includes a first transmission wheel and a second transmission wheel arranged laterally opposite each other. A first drive source is connected to one of the transmission wheels. A chain / transmission belt is wound around the two transmission wheels, and the plane of the chain / transmission belt is vertical. The clamping component includes a mounting plate with a fixing plate on one side and connected to one side of the chain / transmission belt through the fixing plate. The clamping notch is opened on the side of the mounting plate away from the fixing plate. The carcass to be divided is configured to be transported from the first transmission wheel to the second transmission wheel along with the upper part of the chain / transmission belt between the two transmission wheels, so that the carcass to be divided can always move horizontally between the first transmission wheel and the second transmission wheel, ensuring that the dividing work can be carried out smoothly.

[0014] The unloading unit includes an unloading rod, one end of which is located outside the second drive wheel and is coplanar with the plane of the chain / transmission belt. The other end faces the lower side of the drive wheel and is inclined toward the side of the chain / transmission belt where the mounting plate is set. After the carcass is cut, the part of it that is clamped and fixed on the clamping member can fall off the clamping member under the pushing action of the unloading rod during the conveying process with the chain / transmission belt, saving the step of manual handling and thus improving the overall work efficiency.

[0015] The gap between the two guides is adjustable to adjust the size of the gap according to the different thicknesses, sizes or types of carcasses, thereby achieving precise cutting of carcasses of different thicknesses, sizes or types. The gap on the feeding side between the two guides is larger than the gap on the discharging side, so as to facilitate the carcass to enter the gap between the two guides and shrink after entering, so as to facilitate subsequent precise cutting.

[0016] Both guides are horizontally arranged plate-like structures, and the horizontal height of both guides and the material support plate is vertically adjustable. This allows for adjustment of the horizontal height of the two guides according to different sizes or types of carcasses, thereby achieving precise cutting of carcasses of different sizes or types.

[0017] The side of the support plate opposite to the carcass transport direction is also provided with a first guide plate that is inclined and points downwards outwards. The material guide plate is located below the feed end of the gap and is used for guiding and supporting the feed before the carcass is cut.

[0018] The above-mentioned automatic poultry carcass cutting device also includes a control box and a detection mechanism capable of detecting the position of the holding parts and the carcass. The detection mechanism, the first drive source, and the second drive source are all communicatively connected to the control box.

[0019] The above-described method for automatic poultry carcass cutting equipment includes a detection mechanism comprising a first detection mechanism located at the head end of the horizontal conveying unit and capable of detecting the position of the holding component; a second detection mechanism located on the feeding side corresponding to the gap between two guides and capable of detecting the position of the carcass to be cut; and a third detection mechanism located between the gap between the two guides and capable of detecting the position of the carcass within the cutting area of ​​the cutting blade. The cutting method specifically includes the following steps:

[0020] S1: Control the first drive source and the second drive source to operate, the dividing blade rotates, and the holding member moves with the transmission mechanism at a first preset speed;

[0021] S2: Carcass division;

[0022] Specifically, it includes the following two tasks:

[0023] A: Install the carcass;

[0024] AS2.1 When the first detection mechanism detects that the clamping component has reached the position of the first detection mechanism, it controls the transmission mechanism to stop operating and delays for a first preset time. During the first preset time, the manual person hangs the carcass to be divided on the clamping component.

[0025] AS2.2, Repeat step AS2.1;

[0026] B: Dissection of the carcass;

[0027] BS2.1, carcass segmentation:

[0028] The second detection mechanism detects the position of the carcass reaching the second detection mechanism, controls the transmission mechanism to drive the carcass to be divided into the gap between the two guides at a second preset speed, and divides the carcass in the gap by the dividing blade;

[0029] The second preset speed is less than the first preset speed. By adjusting the speed at which the transmission mechanism conveys the carcass to the dividing unit and the speed at which the dividing blade divides the carcass, the equipment can improve dividing efficiency while ensuring dividing quality.

[0030] The portion of the carcass cut off by the dividing blade slides along the second guide plate to the discharge slide plate, and then slides through the discharge slide plate into the first receiving device. The remaining portion of the carcass continues to be transported by the transmission mechanism.

[0031] In the above steps, the carcass is moved to the dividing unit at a relatively fast speed, which helps to quickly send the carcass to be divided into the dividing unit. The carcass is divided at a slower speed, which helps to ensure the accuracy and stability of the dividing process. Specifically, during the carcass dividing process, the slower speed helps to protect the integrity of the carcass and avoid damage to the carcass caused by excessive speed.

[0032] BS2.2 The third detection mechanism detects that the body has moved out of the gap between the two guides and controls the transmission mechanism to resume the first preset speed to continue moving;

[0033] BS2.3 The remaining part of the carcass reaches the position of the unloading unit along with the transmission mechanism, and under the action of the unloading unit, it disengages from the holding member and falls into the second receiving device;

[0034] BS2.4 Repeat steps BS2.1-BS2.3.

[0035] The above describes a method for automatic poultry carcass segmentation using an automated segmentation device: In step S2, if the third detection mechanism detects that the carcass has not moved out of the gap between the two guides, steps AS2.1-AS2.2 will not run until the third detection mechanism detects that the carcass has moved out of the gap between the two guides, at which point steps AS2.1-AS2.2 will begin again.

[0036] The beneficial effects of this invention compared to the prior art are as follows:

[0037] 1. Improved efficiency: The automated segmentation process greatly speeds up the processing of carcasses, significantly improving work efficiency compared to manual segmentation;

[0038] 2. Enhanced safety: Reduces the need for operators to directly contact the cutting blade, lowering safety risks during operation;

[0039] 3. High adaptability: The design of hooking and fixing the carcass to be divided through the snap-fit ​​notch allows the equipment to adapt to the division of carcasses of different specifications. There is no need to perform additional straightening or positioning operations on the carcass, which simplifies the installation process and reduces the division quality problems caused by size differences.

[0040] 4. Ensure segmentation quality: The design of the segmentation unit ensures the posture adjustment and stability of the carcass during the segmentation process, avoids deviation of the segmentation line, and thus improves the accuracy and quality of the cutting.

[0041] 5. Reduced post-processing work: With the first and second receiving devices, the divided carcass parts and the remaining parts can be automatically sorted and collected, eliminating the need for manual selection and sorting, further saving manpower and improving overall work efficiency.

[0055] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0056] Example

[0057] See Figure 1 , Figure 1 This is a schematic diagram of the structure of an automatic poultry carcass cutting device according to this embodiment. It includes a frame 1, a horizontal conveying unit 2, a cutting unit 3, and a control box 8. The cutting unit 3 is located on one side of the horizontal conveying unit 2. The horizontal conveying unit 2 is used to convey the carcasses to be cut. The cutting unit 3 is used to cut the carcasses to be cut as they pass by. The frame 1 includes a support frame 11 and a mounting frame 12 that is detachably mounted on its upper part. The horizontal conveying unit 2 is mounted on the support frame 11. The cutting unit 3 is detachably mounted on the mounting frame 12. The control box 8 is detachably mounted on top of the mounting frame 12. A nylon pad is also provided between the control box 8 and the mounting frame 12. The horizontal conveying unit 2 and the cutting unit 3 are both communicatively connected to the control box 8 and can be controlled by the control box 8. The automated cutting process greatly improves work efficiency compared to manual cutting and reduces the risk of manual operation.

[0058] Regarding the structure of the horizontal conveying unit 2, combined with Figure 2 and Figure 3 Specifically, the horizontal conveying unit 2 includes a first drive source 25 and a transmission mechanism driven by it. The transmission mechanism is provided with a plurality of holding members 5 spaced apart, and each holding member 5 has a notch on one side (e.g., ...). Figure 9 and Figure 10The carcass to be divided can be suspended and fixed to the holding member 5 through the snap-fit ​​notch, and can move with the movement of the transmission mechanism. The carcass to be divided is fixed in the snap-fit ​​notch, so that there is no need to straighten the carcass to be divided during installation. The divided part is suspended under the holding member 5 under the action of gravity, which facilitates the subsequent division processing. The divided part is suspended without any obstruction, so it can be adapted to the division of carcasses of various specifications, and the installation process is simple and easy to operate.

[0059] Regarding the installation structure of the transmission mechanism and the clamping component 5, the transmission mechanism includes a first transmission wheel and a second transmission wheel arranged laterally opposite each other. The first drive source 25 is connected to one of the transmission wheels. A chain 23 / transmission belt is wound around the two transmission wheels, and the plane of the chain 23 / transmission belt is vertical. The clamping component 5 includes a mounting plate 52, one side of which is provided with a fixing plate 51 and is connected to one side of the chain 23 / transmission belt through the fixing plate 51. The clamping notch is opened on the side of the mounting plate 52 away from the fixing plate 51. The carcass to be divided is configured to be transported from the first transmission wheel to the second transmission wheel along with the upper part of the chain 23 / transmission belt between the two transmission wheels, so that the carcass to be divided can always move horizontally between the first transmission wheel and the second transmission wheel, ensuring that the dividing work can be carried out smoothly.

[0060] Regarding the structure of segmentation unit 3, combined with Figures 3-5 Specifically, the dividing unit 3 includes two guides with a gap between them, a cutting mechanism located on one side of the carcass transport path, and a material support plate 34 horizontally located below the gap between the two guides.

[0061] The gap between the two guide members coincides with the transport path of the carcass. The cutting mechanism includes a second drive source 38 and a dividing blade 31 connected to it. The vertical projection of part of the dividing blade 31 is located within the gap between the two guide members. Based on the above design, the carcass to be divided can adjust its posture under the guidance and squeezing action of the two guide members to prevent the carcass from moving randomly. The part of the carcass to be divided that is within the gap can naturally contract, and the division is located within the gap. Therefore, during the subsequent division process, the dividing line can always be located within the gap between the two guide members, so that it will not easily deviate from the division during division, thus improving the cutting quality.

[0062] The material support plate 34 has a second guide plate 36 inclined to the outside and downward on one side along the carcass transport direction. Below the second guide plate 36 is a discharge slide plate 37 inclined to the outside and downward on the support frame 11. The material support plate 34 and the second guide plate 36 are used to support the carcass to be divided during the division process. The discharge slide plate 37 is used to smoothly discharge the divided parts of the carcass to be divided. Below the discharge slide plate 37 is a first receiving device 6. After the carcass is divided, the divided parts slide from the second guide plate 36 to the discharge slide plate 37, and then slide down along the discharge slide plate 37 to the first receiving device 6 for collection.

[0063] Furthermore, the side of the material support plate 34 opposite to the carcass transport direction is also provided with a first guide plate 35 that is inclined to the outside and downward. The first guide plate 35 is used for material guidance and support before the carcass is divided, so that the carcass to be divided can enter the dividing unit 3 smoothly.

[0064] Furthermore, both guides are horizontally arranged plate-like structures, and the gap between the two guides is adjustable. The horizontal height of both guides and the material support plate 34 is vertically adjustable, so as to adjust the size of the gap and the horizontal height of the two guides according to the different thicknesses, sizes or types of carcasses, thereby achieving precise cutting of carcasses of different thicknesses, sizes or types.

[0065] Furthermore, the gap on the feed side between the two guides is larger than the gap on the discharge side, so that the carcass can easily enter the gap between the two guides and contract after entering, so as to facilitate subsequent precise cutting.

[0066] As one of the preferred implementation schemes, combined with Figure 2 and Figure 3 At the end of the horizontal conveying unit 2, there is also a material ejection unit 4. The material ejection unit 4 is configured to push the remaining part of the carcass out of the holding member 5 and fall into the second receiving device 7. The second receiving device 7 is also provided below the material ejection unit 4. The divided part of the carcass and the remaining part of the carcass after the division can fall into the first receiving device 6 and the second receiving device 7 respectively (e.g., Figure 1 As shown in the figure, the manual selection, sorting and collection steps after the segmentation are reduced, saving manpower and improving work efficiency.

[0067] Furthermore, the unloading unit 4 includes an unloading rod 42, one end of which is located outside the second drive wheel and is coplanar with the plane where the chain 23 / transmission belt is located, and the other end faces the lower side of the drive wheel and is inclined toward the side where the hanging plate 52 is set on the chain 23 / transmission belt. After the carcass is cut, the part of it that is clamped and fixed on the clamping member 5 can fall off the clamping member 5 under the pushing action of the unloading rod 42 during the conveying process with the chain 23, saving the step of manual handling and thus improving the overall work efficiency.

[0068] In this embodiment, as a preferred embodiment, see [reference needed]. Figure 2 As shown, the transmission mechanism includes mounting components disposed opposite to each other at both ends of the support frame 11. Each mounting component includes two opposing first support seats 24 and second support seats. A connecting shaft is rotatably provided between the opposing two support seats. The first transmission wheel and the second transmission wheel are keyed to the two connecting shafts, respectively. The first transmission wheel and the second transmission wheel are a first sprocket 21 and a second sprocket 22, respectively. A chain 23 is wound around the two sprockets. The retaining member 5 is connected to the chain 23 through a fixing plate 51 on one side. The retaining notch is opened on the other side of the mounting plate 52. The chain 23 is configured such that the second sprocket 22 is the driving sprocket, the first drive source 25 is the first servo motor, and a worm gear reducer is connected to it to adjust the chain speed. The first servo motor is connected to the second sprocket 22, and the first sprocket 21 is the driven sprocket. The first support seats 24 on both sides of the first sprocket 23 are slide bearing adjustment seats to adjust the tension of the chain 23 to accommodate the segmentation of poultry carcasses of different sizes. Of course, the tensioning structure of the chain 23 can also be a tensioning wheel with an adjustable position on one side of the chain 23. The two methods can be selected according to the actual use scenario.

[0069] Furthermore, the ejector unit 4 also includes a mounting plate 41, which is located on the outside of the second sprocket 22 and is detachably connected to the support frame 11 by bolts. The ejector rod 42 is located on the lower side of the mounting plate 41 facing the second sprocket 22, and the vertical height of the mounting plate 41 is adjustable so that the position of the ejector rod 42 can be adjusted during use to better cooperate with the clamping member 5.

[0070] Combination Figure 4 and Figure 5 In this embodiment, the mounting frame 12 is also provided with a limiting plate 39 along the carcass transport direction. The limiting plate 39 is located outside the clamping member 5. The limiting plate 39 is configured to limit the position of the clamping member 5 to prevent the carcass that is clamped and fixed on the clamping member 5 from coming off the clamping member 5 during the cutting process.

[0071] In this embodiment, the second drive source 38 is a second servo motor, and the mounting frame 12 includes a motor mounting base 121 and a pallet support 122 located on the outer side above the support frame 11, as well as a U-shaped frame located on both sides of the dividing blade 31 along the carcass transport direction.

[0072] The material support plate 34 is located on the upper side of the support plate support 122, and its vertical height on the support plate support 122 is adjustable. The motor mounting base 121 and the two vertical rods 123 in each U-shaped frame are respectively straddling the inner and outer sides of the support frame 11. The opening of the U-shaped frame is set downward. The horizontal bar 124 between the two vertical rods 123 is perpendicular to the carcass transport direction. The servo motor and the dividing blade 31 connected to it are both located on the motor mounting base 121. The dividing blade 31 is located on the outer side of the motor mounting base 121 relative to the servo motor. The limiting plate 39 is horizontally located between the two horizontal bars 124. Its position in the direction perpendicular to the carcass transport direction is adjustable, that is, the distance between it and the clamping member 5 in the direction perpendicular to the carcass transport direction is adjustable.

[0073] Combination Figure 3 , Figure 5 and Figure 6 The two guides are a first guide plate 32 and a second guide plate 33 below it. The first guide plate 32 is horizontally disposed below the two crossbars 124 and is connected to the two crossbars 124 through a first connector. The second guide plate 33 is connected to one of the vertical bars 123 located in front of the snap-fit ​​member through an L-shaped plate, and its vertical height on the vertical bar 123 is adjustable. The two ends of the first guide plate 32 are respectively connected to the two first connectors through L-shaped plates, and the position of the L-shaped plate on the first connector is vertically adjustable. The inner and outer positions of the first guide plate 32 on the L-shaped plate are adjustable.

[0074] Combination Figures 6-8 The mounting frame 12 is also provided with a chain support plate 125 along the carcass transport direction. The chain support plate 125 is a U-shaped strip structure with the opening facing upwards in cross-section. Its lower side is connected to the first connector. The chain support plate 125 is provided with a T-shaped chain support 126 inside. The T-shaped chain support 126 is a T-shaped strip structure with the cross-section protruding upwards. The T-shaped chain support 126 cooperates with the chain 23 located in the dividing unit 3 to support the chain 23 and prevent the chain 23 from sagging during the dividing process. This design improves the dividing quality.

[0075] Combination Figure 7 The inner side of the chain support plate 125 is also provided with a protective side plate 127, whose vertical projection shape is an arc-shaped structure located inside the splitting blade 31, which is used to protect the inner side of the splitting blade 31 and prevent some carcass residue or liquid from splashing during the splitting of the carcass.

[0076] Furthermore, combined Figure 1 Both sprockets are equipped with sprocket guards on the outside, and the dividing blade 31 is equipped with a dividing blade guard on the outside to prevent splashing and improve the safety of the equipment.

[0077] In this embodiment, combined with Figure 9 and Figure 10Specifically, the snap-fit ​​notch of the clamping member 5 includes an inlet section 521 and a hanging section 522 arranged sequentially. The inlet section 521 is located near the outer side of the mounting plate 52 and is flared with its opening facing the outer side of the mounting plate 52. The carcass to be divided is hung on the lower side of the clamping member 5 from the inlet section 521 of the mounting plate 52 to the hanging section 522. The end of the hanging section 522 near the fixing plate 51 has an arc-shaped structure with its opening facing the inlet section 521, so as to increase the contact surface between the end of the hanging section 522 near the fixing plate 51 after the carcass to be divided is hung on the mounting plate 52, thereby improving the stability of the carcass to be divided and the subsequent dividing quality.

[0078] In this embodiment, the chain 23 is a standard part. The connecting plate on the outside of its chain link has the following two situations: the first situation is that the connecting plate is a horizontal plate; the second situation is that the connecting plate is a vertical plate.

[0079] Example 1 can be used in the first case described above. In this case, the angle between the mounting plate 52 and the fixing plate 51 is designed to be 90°-180°, and the fixing plate 51 is horizontally positioned above or below the horizontal plate on the chain link. Figure 10 As shown (the included angle between the mounting plate 52 and the fixing plate 51 is 180°).

[0080] Example 2 can be used in the second case described above. In this case, the angle between the mounting plate 52 and the fixing plate 51 is designed to be no greater than 90 degrees, and the fixing plate 51 is vertically positioned on the outside of the vertical plate on the chain link. Figure 9 As shown (the angle between the mounting plate 52 and the fixing plate 51 is 60°).

[0081] To accommodate the different segmentation requirements of poultry carcass products, the notches of the retaining components 5 are set perpendicularly or obliquely to the conveying direction of the chain 23. For example, for the different segmentation requirements of duck leg (a combination of duck drumstick and duck leg meat) and duck wing (a combination of duck wing root and duck breast meat), the duck leg includes the drumstick and the leg meat connected to it, and the two parts need to be separated directly during segmentation. The duck wing includes the duck wing root and the duck breast meat connected to it, and the two parts need to be separated during segmentation, leaving an extra piece of duck skin on the duck wing root.

[0082] In the cutting of duck legs, the hanging notch is perpendicular to the conveying direction of chain 23 (e.g., Figure 10(Using the installation method of Example 1), during the cutting process, the end of the duck leg that is furthest from the leg meat is hung on the clamping member 5 through the hanging notch on the hanging plate 52. After the duck leg is hung, due to gravity, the end of the duck leg that is furthest from the leg meat, which is commonly known as the part with cartilage, is clamped on the hanging plate 52. At this time, the duck leg is hanging on the clamping member 5 in a suspended state. After the cutting is completed, the cut of the duck leg is a horizontal cut, so that a complete duck leg can be obtained.

[0083] In the segmentation of duck wings, the hanging notch is inclined along the conveying direction of chain 23 (e.g., Figure 9 (Using the installation method of Example 2), during the cutting process, the end of the duck wing root away from the breast meat is hung on the clamping member 5 through the hanging notch on the hanging plate 52. After the duck wing is hung, due to gravity, the end of the duck wing root away from the breast meat, which is commonly known as the part with cartilage, is clamped on the hanging plate 52. At this time, the duck wing is hanging on the clamping member 5 in a suspended state. And because the hanging notch is inclined along the conveying direction of the chain 23, the duck wing is also hanging on the clamping member 5 in an inclined suspended state. After the cutting is completed, the cut of the duck wing root is an inclined cut. The cut duck wing root has an extra piece of duck skin compared to the cutting of the drumstick.

[0084] In this embodiment, the dividing machine also includes a detection mechanism capable of detecting the position of the holding member 5 and the carcass. The detection mechanism, the first servo motor and the second servo motor are all communicatively connected to the control box 8.

[0085] The above-mentioned automatic poultry carcass cutting device is referred to as a cutting machine. In a preferred embodiment, the cutting machine is symmetrically arranged in two sets. When these two sets of symmetrically arranged cutting machines are applied to the cutting of duck legs, since the skin-on part is more difficult to cut, the following layout can be adopted: the skin-on part of the duck leg is set towards the cutting blade 31, while the meat part on the opposite side of the skin-on part is set towards the side away from the cutting blade 31. In this way, when cutting two duck legs on different sides of the chicken carcass, the two duck legs on different sides are cut by these two sets of symmetrically arranged cutting machines respectively, so as to ensure that the two duck legs on different sides can be effectively cut.

[0086] Combination Figure 4 and Figure 8 This embodiment also provides a segmentation method using the above-described automatic poultry carcass segmentation equipment, wherein the detection mechanism includes a corresponding horizontal conveying unit 2 with a front end set (e.g., Figure 4 The first detection mechanism, which can detect the position of the holding member 5, and the feeding side corresponding to the gap between the two guide members (e.g., position a), are also provided. Figure 4The gap between the second detection mechanism (position b) and the corresponding two guides is set to detect the position of the carcass to be cut, and it can also detect the cutting area of ​​the cutting blade 31 (e.g., position b). Figure 4 The third detection mechanism for detecting the position of the carcass within the position between bc (the middle part of the carcass) includes the following steps in the segmentation method:

[0087] S1: Control the first servo motor and the second servo motor to move, the dividing blade 31 rotates, and the clamping member 5 moves with the transmission mechanism at a first preset speed;

[0088] S2: Carcass division;

[0089] Specifically, it includes the following two tasks:

[0090] A: Install the carcass;

[0091] AS2.1 When the first detection mechanism detects that the clamping piece 5 has reached the position of the first detection mechanism, it controls the transmission mechanism to stop operating and delays for a first preset time. During the first preset time, the manual person hangs the carcass to be divided on the clamping piece 5.

[0092] AS2.2, Repeat step AS2.1;

[0093] B: Dissection of the carcass;

[0094] BS2.1, carcass segmentation:

[0095] The second detection mechanism detects the position of the carcass reaching the second detection mechanism, controls the transmission mechanism to drive the carcass to be divided into the gap between the two guides at a second preset speed, and divides the carcass in the gap by the dividing blade 31;

[0096] The second preset speed is less than the first preset speed. For example, the first preset speed is set to 20 cm / s and the second preset speed is set to (10-15) cm / s. By adjusting the speed at which the transmission mechanism conveys the carcass to the dividing unit 3 and the speed at which the dividing blade 31 divides the carcass, the equipment can improve the dividing efficiency while ensuring the dividing quality.

[0097] The portion of the carcass cut off by the dividing blade 31 slides along the second guide plate 36 to the discharge slide plate 37, and then slides through the discharge slide plate 37 into the first receiving device 6. The remaining portion of the carcass continues to be transported by the transmission mechanism.

[0098] In the above steps, the carcass is moved to the dividing unit 3 at a relatively fast speed, which helps to quickly send the carcass to be divided into the dividing unit 3; while the speed of dividing the carcass is relatively slow, which helps to ensure the accuracy and stability of the dividing process. Specifically, during the process of dividing the carcass, the slower speed helps to protect the integrity of the carcass and avoid damage to the carcass caused by excessive speed.

[0099] BS2.2 The third detection mechanism detects that the body has moved out of the gap between the two guides and controls the transmission mechanism to resume the first preset speed to continue moving;

[0100] BS2.3 The remaining part of the carcass reaches the position of the unloading unit 4 along with the transmission mechanism, and under the action of the unloading unit 4, it disengages from the holding member 5 and falls into the second receiving device 7;

[0101] BS2.4 Repeat steps BS2.1-BS2.3.

[0102] The above describes a method for automatic poultry carcass segmentation using an automated segmentation device: In step S2, if the third detection mechanism detects that the carcass has not moved out of the gap between the two guides, steps AS2.1-AS2.2 will not run until the third detection mechanism detects that the carcass has moved out of the gap between the two guides, at which point steps AS2.1-AS2.2 will begin again.

[0103] Preferably, both the first and second detection mechanisms are photoelectric sensors, and the third detection mechanism is a horizontally arranged grating sensor, capable of detecting the segmented area of ​​the dividing blade 31 (e.g., Figure 4 Does the carcass to be cut exist within the position between bc?

[0104] Preferably, the detection mechanism also includes a fourth detection mechanism, which is located on the side away from the unloading unit 4 in the conveying direction of the chain 23, that is, the position of the clamping member 5 after the unloading unit 4 has completed pushing the material. It is used to detect whether there is any remaining part of the carcass on the clamping member 5. The fourth detection mechanism is a photoelectric sensor. When the carcass is divided and there is still a remaining part of the carcass on the clamping member 5 after the unloading unit 4, the photoelectric sensor will detect the abnormality and immediately send a signal to the control box 8. After receiving the signal from the photoelectric sensor, the control box 8 will immediately trigger the alarm device to issue an alarm signal. After hearing the alarm signal, the operator will immediately go to the equipment site to check and manually remove the remaining part of the carcass on the clamping member 5. The existence of the fourth detection mechanism greatly improves the automation level and safety of the equipment, avoids the remaining part of the carcass from re-entering the dividing machine for invalid or incorrect secondary dividing, thereby ensuring the quality of dividing and reducing equipment wear.

[0105] It should be noted that the dividing blade 31 of the present invention should not be simply understood as a single dividing blade 31; its number and arrangement should be expandable within a reasonable range. For example, when the dividing blade 31 of the present invention is preferably two, the two dividing blades 31 are arranged opposite each other and are both horizontally mounted on the motor mounting base 121 via a rotating seat. The two dividing blades 31 are respectively arranged opposite each other on both sides of the rotation center of the rotating seat. The positions on both sides of the rotation center of the rotating seat are the maintenance position and the dividing blade 31 dividing work position, respectively. In use, the positions of the two dividing blades 31 can be switched to switch the two dividing blades 31 to work, so that when one dividing blade 31 is performing dividing work, the other dividing blade 31 is in a maintenance state. The maintenance includes, but is not limited to, cooling, drying, or sharpening the blade edge, etc., to improve the service life of the blades, thereby keeping the equipment in a continuous working state for a long time and improving the overall dividing efficiency of the equipment.
