Description

Technical Field

[0001] This invention relates to the technical field of caged poultry acquisition and cage replacement, specifically to a caged poultry replacement production line. Background Technology

[0002] When selling live poultry, farmers typically pack the poultry into their own cages, stack them, and then transport them to poultry slaughtering and processing plants or other live poultry purchasing companies. Because of their own production and sales needs, these companies, upon receiving the live poultry from the farmers, need to remove the poultry from the cages and then pack them into their own dedicated cages so that the slaughtering and processing plants or other purchasing companies can perform their respective subsequent processing.

[0003] In addition, poultry slaughtering and processing enterprises or other live poultry purchasing enterprises have corresponding requirements for the size and health of the live poultry produced by live poultry farmers. Therefore, when the operators take the live poultry out of the farmers' cages and put them into their own special cages, they can conduct quality inspections on the poultry of the farmers they are purchasing. Only those that meet the requirements will be purchased, and those that do not meet the requirements will be returned to the farmers.

[0004] Currently, the process of removing live poultry from farmers' cages and placing them into dedicated cages at poultry slaughtering and processing enterprises or other live poultry purchasing enterprises involves unloading stacks of cages from farmers' transport vehicles, dismantling the stacks to obtain multiple cages containing live poultry, and then sequentially transferring the cages to a processing station. Poultry meeting the requirements is placed into the purchasing enterprise's dedicated cages, while non-compliant poultry is returned to the farmers. Finally, empty cages or cages containing non-compliant poultry are returned to the farmers, while compliant poultry is placed into dedicated cages, stacked, and transferred to the next process. This entire process still requires significant manual labor, resulting in high labor costs for quality inspection and relatively low efficiency. Furthermore, the more people involved in the process, the higher the probability of avian influenza transmission and the greater the potential losses.

[0005] Currently, in the aforementioned processes, unloading stacked cages or transferring cage stacks can be done using forklift robots or lifting equipment, which can be remotely controlled or operated unmanned. However, the processes of unstacking and stacking cages, transferring cages after unstacking and before stacking, and removing live poultry from the cages (for quality inspection) and then (after quality inspection) repackaging the live poultry into specialized cages still require manual intervention. Therefore, how to further improve the automation of poultry cage changing operations and increase the efficiency of live poultry cage changing is a technical problem that urgently needs to be solved by those skilled in the art.

[0006] Through research by the applicant's R&D team, it was discovered that currently, the processes of removing live poultry from cages for quality inspection and simultaneously inspecting them, as well as repackaging them, are difficult to automat. This is because the poultry will instinctively avoid the cages, and the inspection requirements vary depending on the species, the farmer, and the intended use of the poultry. Therefore, fully mechanized and automated operation is not yet possible. To ensure the safety of both the poultry and the operators, protective measures must be taken by the operators during the quality inspection process. However, the process of transferring the cages containing live poultry after unpacking them to the operators and then transferring and stacking the dedicated cages containing live poultry can be mechanized and automated. Therefore, the technical solution of this patent application was developed. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cage-changing production line for caged poultry. This line transports the cages containing the live poultry to be changed after the cage stacks are unstacked during the live poultry changing process to the operators, and then transports and stacks the cages containing the live poultry that have been changed. This achieves mechanized and automated operation, further improving the efficiency of live poultry changing and reducing the risk of workers being infected with viruses by live poultry.

[0008] The technical solution adopted in this invention is: A cage-loading poultry production line includes a depalletizing and feeding conveyor, a depalletizer, a cage conveyor B, an operating table, a palletizing and feeding conveyor, a palletizer, and a palletizing and discharging conveyor connected in sequence. A return conveyor is also provided at the operating table. A depalletizing conveyor is connected between the depalletizing and feeding conveyor and the cage conveyor B. The depalletizing conveyor passes through the bottom of the depalletizer, with its starting end B and ending end B extending out from opposite ends of the depalletizer. A palletizing conveyor is also connected between the palletizing and feeding conveyor and the palletizing and discharging conveyor. The palletizing conveyor passes through the bottom of the palletizer, with its starting end F and ending end F extending out from opposite ends of the palletizer.

[0009] A further improvement of the present invention is that the depalletizer includes a fixed frame A, within which a vertically movable lifting frame A is provided. The lifting frame A moves vertically and reciprocally via a lifting drive piston A fixed to the fixed frame A. The depalletizing conveyor is fixed at the bottom of the fixed frame A at a position corresponding to the range of the lifting frame A. The sidewalls of the fixed frame A facing and away from the depalletizing conveyor, corresponding to the position of the lifting frame A, are open. The sidewall of the lifting frame A facing the depalletizing conveyor forms an inlet. The sidewall of the lifting frame A away from the depalletizing conveyor is provided with a backstop A. The conveying start end B of the depalletizing conveyor extends sequentially from the inlet and the open side of the fixed frame A to the lifting frame A and the fixed frame A. The conveying end end B of the depalletizing conveyor extends sequentially from below the backstop A and the open side of the fixed frame A to the lifting frame A and the fixed frame A. The lifting frame A is equipped with clamping mechanisms A on the lower part of both sides of the destacking conveyor in the conveying direction. When the lifting frame A moves downward to its maximum stroke, the bottom of the retaining frame A is higher than the destacking conveyor and lower than the top of the cage A conveyed by the destacking conveyor. The top of the lifting frame A is higher than the top of the cage stack A conveyed on the destacking conveyor, and the bottom of both sides of the lifting frame A is lower than the destacking conveyor. At this time, the clamping mechanism A is used to clamp the bottommost cage A or the bottommost and above cage A of the cage stack A conveyed to the range of the lifting frame A. When the lifting frame A moves upward to its maximum stroke, the rising height of the lifting frame A is greater than the height of the cage A. The bottom of the retaining frame A is higher than the top of the cage A conveyed by the destacking conveyor, and the bottom of both sides of the lifting frame A is lower than the top of the cage A conveyed by the destacking conveyor. The clamping mechanism A is driven by a clamping drive piston A provided on the lifting frame A.

[0010] A further improvement of the present invention is that the palletizing machine includes a fixed frame B, within which a vertically movable lifting frame B is provided. The lifting frame B moves up and down reciprocally via a lifting drive piston B fixed to the fixed frame B. The palletizing conveyor is fixed at a position on the bottom of the fixed frame B corresponding to the range of the lifting frame B. The sidewalls of the fixed frame B facing and away from the palletizing conveyor, corresponding to the position of the lifting frame B, are open. On both sides of the open side of the fixed frame B facing away from the palletizing conveyor, there are openable and closable pallet-blocking frames B. The bottom of the pallet-blocking frames B is higher than... The palletizing conveyor is positioned below the top of the cage B being conveyed by the palletizing conveyor. The baffle frames B are driven by opening and closing pistons located on the fixed frame B. The side wall of the lifting frame B facing the palletizing conveyor has baffle frames, with the bottom of the baffle frames forming an inlet between the baffle frames and the palletizing conveyor. The side wall of the lifting frame B facing away from the palletizing conveyor is open, forming an outlet. The conveying start F of the palletizing conveyor extends sequentially outward from the inlet and the open side of the fixed frame B, and the conveying end F extends sequentially from the open side of the lifting frame B and below the baffle frames B. An extension lifting frame B and a fixed frame B are provided. The lower part of the lifting frame B, located on both sides of the palletizing conveyor in the conveying direction, is equipped with clamping mechanisms B. When the lifting frame B moves downward to its maximum stroke, the bottom of the cage baffle is higher than the palletizing conveyor but lower than the top of the cage B being conveyed by the palletizing conveyor. The top of the lifting frame B is higher than the top of the palletized stack B being conveyed by the palletizing conveyor, and the bottom sides of the lifting frame B are lower than the palletizing conveyor. At this time, the clamping mechanisms B are used to clamp the bottommost cage B or the bottommost and above cage B within the range of the lifting frame B. When the lifting frame B moves upward... At the maximum stroke, the lifting frame B rises to a height greater than the cage B, the bottom of the cage retainer is higher than the top of the cage B conveyed by the palletizing conveyor, and the sides of the lifting frame B are lower than the top of the cage B conveyed by the palletizing conveyor. The clamping mechanism B is driven by a clamping drive piston B located on the lifting frame B. When the opening and closing pistons drive the corresponding retainer B to close, the distance between the retainer Bs is less than the width of the cage B conveyed by the palletizing conveyor. When the opening and closing pistons drive the corresponding retainer Bs to open, the distance between the retainer Bs is greater than the width of the cage B conveyed by the palletizing conveyor.

[0011] A further improvement of the present invention is that a retaining side frame for the stack A is fixedly provided on one side of the stacking and feeding conveyor frame.

[0012] A further improvement of the present invention is that a cage conveyor frame A is connected between the conveying end B of the destacking conveyor frame and the conveying beginning D of the cage conveyor frame B. The cage conveyor frame A is equipped with a cage conveyor belt and a lifting baffle plate A. When the lifting baffle plate A moves upward to its maximum stroke, the top of the lifting baffle plate A is higher than the cage conveyor belt at the corresponding position. When the lifting baffle plate A moves downward to its maximum stroke, the top of the lifting baffle plate A is lower than the cage conveyor belt at the corresponding position.

[0013] A further improvement of the present invention is that the operating platform is located on one side of the cage conveyor frame B, and there is at least one operating platform. When there are multiple operating platforms, they are arranged along the conveying direction of the conveyor frame.

[0014] A further improvement of the present invention is that a return conveyor is fixedly provided above the cage conveyor B, and the conveying direction of the return conveyor is parallel to the conveying direction of the intermediate conveyor.

[0015] A further improvement of the present invention is that guide side plates are fixedly provided on both sides of the palletizing and feeding conveyor. The spacing between the guide side plates decreases along the conveying direction of the palletizing and feeding conveyor. The guide side plates are connected to the side edge of the operating table at the position corresponding to the conveying start E of the palletizing and feeding conveyor. The guide side plates are connected to the side edge of the palletizing and feeding conveyor at the position corresponding to the conveying end E of the palletizing and feeding conveyor, and to the side edge of the conveying start F of the palletizing and feeding conveyor.

[0016] A further improvement of the present invention is that the palletizing and feeding conveyor includes multiple guide support rods A arranged parallel to each other along the conveying direction of the palletizing and feeding conveyor in the middle, and also includes guide support rods B symmetrically arranged on both sides of the guide support rods A. The guide support rods B are inclined inward along the conveying direction of the palletizing and feeding conveyor.

[0017] A further improvement of the present invention is that an inwardly protruding arc-shaped guide plate is fixed to the opposing end face of the guide side upright plate, and the two ends of the arc-shaped guide plate are respectively connected to the two ends of the guide side upright plate.

[0018] A further improvement of the present invention is that the palletizing and unloading conveyor is further provided with a lifting baffle plate. When the lifting baffle plate moves upward to the maximum stroke position, the top of the lifting baffle plate is higher than the contact surface between the corresponding position of the palletizing and unloading conveyor and the conveyed cage. When the lifting baffle plate moves downward to the maximum stroke position, the top of the lifting baffle plate is lower than the contact surface between the corresponding position of the palletizing and unloading conveyor and the conveyed cage.

[0019] The beneficial effects of the invention are: First, the cage-changing production line for caged poultry of the present invention conveys the cage containing the live poultry to be changed to the operator after the cage stack is unstacked during the live poultry changing process, and conveys and stacks the cage containing the live poultry that has been changed, realizing mechanized and automated operation, which further improves the efficiency of live poultry changing and reduces the risk of workers being infected with viruses by live poultry.

[0020] Secondly, in the cage-loading poultry production line of the present invention, the cage stack A conveyed by the destacking and feeding conveyor is destacking machine into cage body A, and then conveyed to the operating table by cage body conveyor B to change the live poultry in cage body A or to inspect the quality at the same time. The live poultry that meets the requirements is put into cage body B and stacked and fed to the palletizer conveyor to the palletizer to be stacked into cage stack B, and then conveyed to the palletizing and unloading conveyor for stacking and turnover. The live poultry that does not meet the requirements is put back into cage body A, and the empty cage body A is conveyed to the farmer for processing by the return conveyor.

[0021] Third, the cage-changing production line for caged poultry of the present invention, through the structure of the destacking machine, can destacking the stacked cages A formed by stacked cages A according to the rhythm of live poultry changing production, and separating each cage A of the stacked cages A in sequence, so that subsequent operators can take out the live poultry for changing.

[0022] Fourth, the cage-changing production line for caged poultry of the present invention, through the structure of the destacking machine, separates the cage body A from the bottom up from the stack of cages A. This method simplifies the structure of the destacking machine and facilitates the direct transfer of the destacking cage body A, further improving production efficiency.

[0023] Fifth, in the cage-loading poultry changing production line of the present invention, the destacking conveyor and the intermediate conveyor A are connected by the cage conveyor frame, and the lifting baffle plate A set on the cage conveyor frame A allows the cage conveyor frame A to pause the conveying of cages A separated by the destacking machine according to the number of cages A on the cage conveyor frame B. This avoids the excessive conveying of cages A on the cage conveyor frame B, which would cause the cages A to accumulate at the end of the cage conveyor frame B, resulting in an excessive workload for the operators at the end of the cage conveyor frame B.

[0024] Sixth, the cage-loading poultry production line of the present invention, through the guide support rod B and guide side plate structure of the palletizing and feeding conveyor frame, facilitates the operator to convey the cage B containing the required live poultry to the palletizer.

[0025] Seventh, the cage-changing production line for caged poultry of the present invention, through the inwardly protruding arc-shaped guide plate provided on the guide side upright plate, can not only prevent the corners of the cage body B from getting stuck on the guide side upright plate, so that the cage body B can be guided and conveyed more smoothly into the conveying start end F of the palletizing conveyor, but also the cavity between the arc-shaped guide plate and the guide side upright plate can also make the arc-shaped guide plate elastic, thereby facilitating the absorption of the impact between the cage body B and the arc-shaped guide plate and avoiding damage to the cage body B.

[0026] Eighth, the cage-loading poultry production line of the present invention, through the structure of the palletizer, can stack cages B containing live poultry that meet the requirements in sequence to form cage stacks B, and discharge cage stacks B, thereby improving the efficiency of turnover of live poultry that meet the requirements.

[0027] Ninth, the cage-loading poultry changing production line of the present invention, through the structure of the palletizer, allows the cage stacks B to be stacked from bottom to top. This method simplifies the structure of the palletizer and makes it easy to directly stack the cages B that are conveyed to the palletizer at the bottom of the cage stacks B, greatly improving stacking efficiency and further improving production efficiency.

[0028] Tenth, the cage-loading poultry production line of the present invention, through the action of the stacking and unloading conveyor frame, conveys the cage stack B to the designated position by the limiting action of the lifting baffle plate, so that the subsequent automated equipment can directly unload and turn over at the designated position, further improving production efficiency.

[0072] The lifting frame B901 has multiple horizontal clamping rods B905 symmetrically arranged from bottom to top on both sides. Each horizontal clamping rod B905 is oscillatingly connected to the corresponding side of the lifting frame B901 through its own swing shaft B918. The swing shafts B918 located on the same side of the lifting frame B901 are connected by one or more connecting rods D920. The connecting rods D920 drive the swing shafts B918 on the same side of the lifting frame B901 to swing simultaneously by equal angles.

[0073] Lifting guide rods B908 are fixedly installed on both sides of the fixed frame B900. Sliding sleeves B909 matching the lifting guide rods B908 are fixedly installed on both sides of the lifting frame B901. The lifting drive piston B902 is fixed to the top of the fixed frame B900.

[0074] One side of the fixed frame B900 is sequentially equipped with a bottom limit sensor B925, a middle limit sensor B926, and a top limit sensor B927 from bottom to top. The lifting frame B901 is fixed with a lifting limit rod B924, which moves up and down between the bottom limit sensor B925 and the top limit sensor B927. When the lifting limit rod B924 corresponds to the middle limit sensor B926, the lifting height of the lifting frame B901 is greater than the height of the cage B, and the bottom of the cage frame is higher than the top of the cage B conveyed by the palletizing conveyor 8.

[0075] Both ends of the swing shaft B918 are rotatably connected to the crossbar C910 fixed on the side wall of the lifting frame B901.

[0077] The lifting drive piston B902, the opening and closing piston 906, and the clamping drive piston B917 are all powered by a hydraulic station B916, which is fixed to the top of the fixed frame B900.

[0078] The palletizing conveyor 8 includes a set of parallel transmission frames B800 fixed to the fixed frame B900. Palletizing conveyor chains 17 are driven and connected to each transmission frame B800, and each palletizing conveyor chain 17 is synchronously driven by a palletizing conveyor drive motor 801. Multiple swing plates B802 are sequentially arranged between the transmission frames B800 along the conveying direction of the palletizing conveyor 8. Each swing plate B802 swings around a swing axis B, the two ends of which are connected to corresponding transmission frames B800. In its free state, the swing plate B802 tilts upwards along the conveying direction of the palletizing conveyor 8. Furthermore, the highest point of the swing plate B802 is higher than the top surface of the palletizing conveyor chain 17, and the lowest point is lower than the top surface of the palletizing conveyor chain 17. On the opposing surface of the transmission frame B800, at the position of the swing plate B802, a transmission position sensor B803 is respectively provided. When the swing plate B802 is in a free state and when it comes into contact with the cage B or the cage stack B conveyed by the palletizing conveyor frame 8, the transmission position sensor B803 corresponding to the swing plate B802 generates different signals. At least one swing plate B802 is provided between the transmission start end F of the palletizing conveyor frame 8 and the cage inlet 903 of the lifting frame B901.

[0079] A lifting baffle plate B806 is also provided between the transmission frames B800 and on the side of the lifting frame B901 facing the palletizing conveyor 8 at the starting end F. When the lifting baffle plate B806 moves downward to the maximum stroke, the top of the lifting baffle plate B806 is lower than the top of the palletizing conveyor chain 17.

[0088] The operating platform 6 is located on one side of the cage conveyor frame B5. There is at least one operating platform 6. When there are multiple operating platforms 6, they are arranged along the conveying direction of the conveyor frame B5.

[0089] Above the cage conveyor frame B5, a return conveyor frame 11 is also fixedly installed, and the conveying direction of the return conveyor frame 11 is parallel to the conveying direction of the intermediate conveyor frame 5.

[0090] Guide side plates 16 are fixedly provided on both sides of the palletizing and feeding conveyor 7.

[0091] The palletizing and feeding conveyor 7 includes multiple guide support rods A arranged parallel to the conveying direction of the palletizing and feeding conveyor 7 in the middle, and also includes guide support rods B19 symmetrically arranged on both sides of the guide support rods A. The guide support rods B19 are inclined inward along the conveying direction of the palletizing and feeding conveyor 7.

[0092] The guide support rod B19 is arranged parallel to the guide side plate 16 on the same side.

When the lifting baffle plate 18 moves downward to the maximum stroke position, the top of the lifting baffle plate 18 is lower than the contact surface between the corresponding position of the palletizing and unloading conveyor 10 and the conveyed cage.

[0095] At least one operating table 6 is provided on one side of the conveying end D of the cage conveyor frame B5.

[0096] The conveying end A of the destacking and loading conveyor 1 is connected to the conveying beginning B of the destacking conveyor 2. The conveying end B of the destacking conveyor 2 is connected to the conveying beginning C of the cage conveyor A4. The conveying end C of the cage conveyor A4 is connected to the conveying beginning D of the cage conveyor B5. One end of the operating table 6 is connected to one side of the cage conveyor B5. The other end of the operating table 6 is connected to the conveying beginning E of the stacking and loading conveyor 7. The conveying end E of the stacking and loading conveyor 7 is connected to the conveying beginning F of the stacking conveyor 8. The conveying end F of the stacking conveyor 8 is connected to the conveying beginning G of the stacking and unloading conveyor 10. The conveying beginning H of the return conveyor 11 is located at the end where the conveying beginning D of the cage conveyor B5 is located. The conveying end H of the return conveyor 11 is located at the end where the conveying end D of the cage conveyor B5 is located.

[0097] When this application is used, the cage stack A formed by the cages provided by the farmers is loaded onto the destacking and loading conveyor frame 1 by a forklift or other device, and the cage stack A on the destacking and loading conveyor frame 1 is made to make contact with the blocking side frame 12. The cage stack A conveyed by the destacking and loading conveyor frame 1 is conveyed along the blocking side frame 12 to the destacking conveyor frame 2, and then conveyed to the destacking machine 3 through the destacking conveyor chain 13 of the destacking conveyor frame 2.

[0098] When the cage stack A is conveyed by the destacking conveyor chain 13, the lifting drive piston A302 drives the lifting frame A301 to move until the lifting limit rod A324 corresponds to the middle limit sensor A326, and the clamping drive piston A305 drives the horizontal clamping rod A304 to swing away from the cage stack A to the maximum stroke. When the cage stack A passes the swing plate A202, the signal of the conveying position sensor A203 corresponding to the swing plate A202 changes, and the signal of the conveying position sensor A203 indicates that the cage stack A is inside the lifting frame A301 and is blocked by the stack blocking frame A317. When in the limit position, the destacking conveyor chain 13 pauses conveying, and then the clamping drive piston A305 drives the horizontal clamping rod A304 to swing towards the direction of the cage stack A until it clamps the second bottom cage A or the second bottom and above cage A of the cage stack A; then the lifting drive piston A302 drives the lifting frame A301 to move upward until the lifting limit rod A324 corresponds to the top limit sensor A327. At this time, the destacking conveyor chain 13 resumes conveying, thereby conveying the bottom cage of the cage stack A that was not clamped by the horizontal clamping rod A304 to leave the lifting frame A301 and the fixed frame A300 and conveying it. The cage A is conveyed to the cage conveyor A4, and the cage A passes the swing plate A202 corresponding to the destacking conveyor 2, causing the signal of the conveying position sensor A203 corresponding to the swing plate A202 to change. When the signal of the conveying position sensor A203 indicates that the cage A is in the state of being conveyed to leave the destacking conveyor chain 13, the destacking conveyor chain 13 stops conveying again. Then, the lifting drive piston A302 drives the lifting frame A301 to move downwards until the lifting limit rod A324 corresponds to the bottom limit sensor A325. At this time, the bottommost cage A of the cage stack A, which is clamped by the horizontal clamping rod A304, is in contact with the destacking conveyor. When the conveyor chain 13 contacts, the clamping drive piston A305 drives the horizontal clamping rod A304 to swing away from the stack A to release the cage A of the remaining stack A on the destacking conveyor chain 13. Then, the lifting drive piston A302 drives the lifting frame A301 to move upward until the lifting limit rod A324 corresponds to the middle limit sensor A326, so that the horizontal clamping rod A304 can clamp the second bottom cage A or the second bottom and above cage A of the remaining stack A again. The above actions are repeated so that the cage A can be destacking and conveyed to the cage conveyor frame A4 in sequence.

[0099] Cage A, which is transferred to cage conveyor A4, is then transferred to cage conveyor B5 via cage conveyor belt 14. When there are too many cages A on cage conveyor B5, the lifting baffle plate A15 of cage conveyor A4 moves upward to its maximum stroke position so that cages A on cage conveyor A4 will no longer be transferred to cage conveyor B5.

[0100] Cage A, which is conveyed to cage conveyor B5, is transported along with cage conveyor B5. When cage A is transported to the position of operating table 6 along with cage conveyor B5, the operator transfers cage A from cage conveyor B5 to operating table 6 so that the operator can conduct quality inspection on the poultry in cage A.

[0101] Operators remove poultry from cage A for quality inspection. If the poultry meets the quality inspection requirements, it is placed into cage B, and cage B containing the compliant poultry is transferred to the palletizing and feeding conveyor 7. Simultaneously, cage A containing the removed poultry is transferred to the return conveyor 11. If the removed poultry does not meet the quality inspection requirements, it is placed back into cage A, and cage A containing the non-compliant poultry is transferred to the return conveyor 11. The palletizing and feeding conveyor 7 conveys cage B to the palletizing conveyor 8, and then to the palletizing machine 9 via the palletizing conveyor chain 17 of the palletizing conveyor 8. The return conveyor 11 conveys cage A to the cage A recycling area at the end H of the return conveyor 11, so that farmers can recycle cage A.

[0102] When the cage stack B is conveyed by the palletizing conveyor chain 17, the lifting drive piston B902 drives the lifting frame B901 to move until the lifting limit rod B924 corresponds to the middle limit sensor B926, and the clamping drive piston B917 drives the horizontal clamping rod B905 to swing backward to the maximum stroke. Meanwhile, the opening and closing pistons 906 drive their respective corresponding pallet stop frames B904 to close, making the distance between the pallet stop frames B904 less than the width of the cage stack B conveyed by the palletizing conveyor chain 8. When the cage B passes the swing plate B8... 02 causes a change in the signal of the transmission position sensor B807 corresponding to the swing plate B802. When the signal from the transmission position sensor B807 indicates that the cage B is inside the lifting frame B901, the lifting drive piston B902 moves the lifting frame B901 until the lifting limit rod B924 corresponds to the bottom limit sensor B925, and the lifting baffle plate B806 moves upward to its maximum stroke position to block the subsequent transmission of cage B by the palletizing conveyor chain 17. When the signal from the transmission position sensor B807 indicates that the cage B is inside the lifting frame B901, the lifting drive piston B902 moves the lifting frame B901 until the lifting limit rod B924 corresponds to the bottom limit sensor B925, and the lifting baffle plate B806 moves upward to its maximum stroke position to block the subsequent transmission of cage B by the palletizing conveyor chain 17. When the cage B inside the lifting frame B901 is blocked by the stacking bracket B904, the palletizing conveyor chain 17 pauses its conveying. Then, the clamping drive piston B917 drives the horizontal clamping rod B905 to swing towards the cage B until it clamps the cage B. Then, the lifting drive piston B902 moves the lifting frame B901 upward until the lifting limit rod B924 aligns with the top limit sensor B927, thereby lifting the cage B clamped by the horizontal clamping rod B905 to its maximum stroke. Then, the lifting plate 806... The palletizing conveyor 17 moves downward to the maximum stroke position and then conveys the palletizing and loading conveyor 7 to another cage B of the palletizing conveyor 8. When the cage B passes the swing plate B802, the signal of the conveying position sensor B807 corresponding to the swing plate B802 changes. When the signal of the conveying position sensor B807 indicates that the cage B is inside the lifting frame B901, the lifting baffle plate B806 moves upward again to the maximum stroke position to block the cage B subsequently conveyed by the palletizing conveyor 17.When the position sensor B807 detects that the cage B inside the lifting frame B901 is blocked by the retaining frame B904, the palletizing conveyor chain 17 pauses again. Then, the lifting drive piston B902 moves the lifting frame B901 downwards until the lifting limit rod B924 aligns with the middle limit sensor B926. At this point, the cage B clamped by the horizontal clamping rod B905 is placed on top of the other cage B that the palletizing conveyor chain 17 has just delivered and blocked by the retaining frame B904, forming a cage stack B. Then, the clamping drive piston B17 drives the horizontal clamping rod B905 to move further away. The mechanism swings away from the stack B to release the cage body B of the stack B on the palletizing conveyor chain 17. Then, the lifting drive piston B902 drives the lifting frame B901 downwards again until the lifting limit rod B924 aligns with the bottom limit sensor B925, so that the subsequent horizontal clamping rod B905 can clamp the bottommost cage body B or the cage body B above the bottom of the stack B again. This action is repeated so that as more cage bodies B are added to the stack B on the palletizing conveyor chain 17, when the horizontal clamping rod B905 clamps the stack B on the palletizing conveyor chain 17 again, the top of the stack B is aligned with the lifting frame B901. When the height difference between the tops is less than the height of cage B, the lifting drive piston B902 drives the lifting frame B901 downwards again until the lifting limit rod B924 aligns with the middle limit sensor B926. Then, the clamping drive piston B917 drives the horizontal clamping rod B905 to release the clamped cage stack B and place it on the cage B conveyed by the palletizing conveyor chain 17, thus completing the palletizing of cage stack B. Then, the opening and closing pistons 906 drive their respective corresponding palletizing baffles B904 to open, and the lifting baffle plate B806 moves upwards again to its maximum stroke position. Then, the palletizing conveyor chain... 17. The palletizer conveys the cage B to the palletizing and unloading conveyor 10 again. When the cage B passes the swing plate B802, the signal of the conveying position sensor B807 corresponding to the swing plate B802 changes. When the signal of the conveying position sensor B807 indicates that the cage B is in the state of leaving the lifting frame B901, the opening and closing pistons 906 drive the corresponding blocking frames B904 to close. At the same time, the lifting blocking plate B806 moves down again to the maximum stroke position. The previous steps are repeated so that the palletizer 9 can palletize the cages B subsequently conveyed by the palletizing conveyor chain 17.

[0103] The cage stack B, which is conveyed to the palletizing and unloading conveyor 10, moves along the palletizing and unloading conveyor 10 to the conveying end G of the palletizing and unloading conveyor 10, and then the cage stack B is transferred and loaded onto a truck by a forklift or crane.

[0104] Before the cage stack B conveyed to the end G of the palletizing and unloading conveyor 10 has been turned over and left the palletizing and unloading conveyor 10, the lifting baffle plate 18 on the palletizing and unloading conveyor 10 moves upward to the maximum stroke position, thereby blocking the other cage stack B conveyed by the palletizing conveyor chain 17 of the palletizing and unloading conveyor 8 at the beginning G of the palletizing and unloading conveyor 10, so as to avoid the cage stack B interfering with the turnover of the cage stack B that is already located at the end G of the palletizing and unloading conveyor 10.

[0113] Each drive swing frame B929 located on the same side of the lifting frame B901 is connected by one or more connecting rods F932. The connecting rods F932 drive each drive swing frame B929 on the same side of the lifting frame B901 to swing at the same angle simultaneously.

[0114] The swing axis A328 of each drive swing frame A330 consists of multiple pins A arranged coaxially along the top opposing side edges of the drive swing frame A330; the swing axis B918 of each drive swing frame B929 consists of multiple pins B arranged coaxially along the top opposing side edges of the drive swing frame B929.

[0115] The destacking machine disassembles the cage stack A into cage body A, which is then conveyed to the operating table via cage body conveyor B. The live poultry in cage body A undergoes quality inspection. Live poultry that meets the quality inspection requirements are loaded into cage body B and conveyed to the palletizer via the palletizing conveyor to form cage stack B. After being conveyed to the palletizing and unloading conveyor for stacking and turnover, live poultry that does not meet the quality inspection requirements are returned to cage body A, and empty cage bodies A are also conveyed to the farmers for processing via the return conveyor.

[0116] The destacking machine disassembles the cage stack A into cage body A, which is then conveyed by the destacking and feeding conveyor frame. The cage body conveyor frame B then transfers the cages to the operating table for changing the live poultry in cage body A and for quality inspection.

[0117] The structure of the destacking machine allows for the disstacking of stacked cages A according to the production rhythm of live poultry cage changing. It separates each cage A from the stacked cages A in sequence, so that subsequent operators can take live poultry for cage changing and conduct quality inspection during the live poultry cage changing process.

[0118] By using the structure of the destacking machine, the cage A is destacking and separating from the bottom up. This method simplifies the structure of the destacking machine and facilitates the direct transfer of the destacking cage A, further improving production efficiency.

[0119] By using the driving swing rod A and the auxiliary swing rod A, a parallelogram linkage mechanism can be formed with the connecting crossbar A and the connecting crossbar B. Since the connecting crossbar B is in a fixed horizontal position, the connecting crossbar A can maintain a horizontal position during the swinging process and will not rotate during the swinging process, thus ensuring the gripping effect of the horizontal clamping rod A on the cage stack A.

[0120] The linkage mechanism enables the multiple horizontal clamping rods A set on both sides of the lifting frame A to move simultaneously and synchronously, further ensuring the clamping effect.

[0121] By introducing the vertical plate, it is easy for the cage stack A to smoothly enter the elevator frame A.

[0122] By cooperating with the stacking support frame and the stacking conveyor frame, the stacking support frame can block the cage A while also forming the cage outlet between the stacking support frame and the stacking conveyor frame after the elevator frame A rises.

[0123] Through the action of the guide and limit rod, the destacking cage A can be smoothly conveyed along the destacking conveyor to the cage conveyor A.

[0124] The palletizer loads qualified live poultry into cages B, stacks them into cage stacks B, and then conveys them to the palletizing and unloading conveyor for stacking and turnover.

[0125] Through the structure of the palletizer, the cages B containing the required live poultry can be stacked into a pallet B according to the rhythm of the live poultry changing production, and the pallet B can be transported out as a whole for subsequent turnover.

[0126] The palletizer's structure allows cages B containing compliant live poultry to be stacked sequentially to form a pallet B, which is then discharged, thus improving the efficiency of handling compliant live poultry.

[0127] By utilizing the structure of the palletizer, cages B are stacked from bottom to top, simplifying the structure of the palletizer and making it easier to directly stack the cages B delivered to the palletizer at the bottom of the stack. This significantly improves stacking efficiency and further enhances production efficiency.

[0128] By using the driving swing arm B and the auxiliary swing arm B, a parallelogram linkage mechanism can be formed with the connecting crossbar C and the connecting crossbar D. Since the connecting crossbar D is in a fixed horizontal position, the connecting crossbar C can drive the horizontal clamping bar B to maintain a horizontal position during the swing process and will not rotate during the swing process, thus ensuring the clamping effect of the horizontal clamping bar B on the cage stack B.

[0129] The linkage mechanism enables the multiple horizontal clamping rods B installed on both sides of the lifting frame B to move simultaneously and synchronously, further ensuring the clamping effect.

[0130] The guide and limiting plate allows cage B to enter the elevator frame B neatly, facilitating the sequential stacking of cages B and ensuring the stability of the resulting cage stack B.

[0131] By cooperating with the stacking conveyor, the stacking support frame B can block the cage B while also creating sufficient space for the cage B to enter between the stacking support frame B and the stacking conveyor after the elevator frame B rises.

[0132] By cooperating with the cage inlet below the cage frame and the lifting cage plate B set on the palletizing conveyor frame, the cage inlet can be opened and closed in accordance with the palletizing program in the lifting frame B, so as to avoid the cage B that has just been transferred to the palletizing conveyor frame from affecting the palletizing operation in the lifting frame B.

[0133] By opening and closing the stacking rack B, the cage stack B can reach its maximum stacking height or be transferred outward after reaching the required stacking height according to production requirements, thereby improving subsequent turnover efficiency.
