Description

Technical Field

[0001] The invention relates to the technical field of poultry food processing, and in particular to a feeding robot for a poultry slaughtering line. Background Art

[0002] Poultry meat has the advantages of high protein, low fat and rich nutrition. With the continuous development of the poultry industry and the increasing demand for poultry food, a complete industrial chain of poultry scale breeding, slaughtering and processing, and poultry food sales has been formed. Among them, the slaughtering link is the key link in the poultry industry chain. The automated slaughtering of poultry can not only reduce the safety hazards in the processing of poultry food, but also improve the labor intensity and working environment of practitioners. The existing technology has studied and developed automated processing equipment for slaughtering, feathering, cleaning, cutting and other processing links, promoting the transformation and development of my country's poultry slaughtering industry towards standardization and scale. However, in the pre-processing link, workers need to move the baskets unloaded from the transport vehicle to the slaughtering production line. The baskets are also called poultry turnover baskets, ingot-shaped chicken baskets, poultry transport cages, ingot baskets, etc. in the industry, and live poultry are placed inside. Generally, about 8 baskets are stacked together and transferred from the transport vehicle to the lifting equipment. Workers need to stand on the lifting equipment and transfer the upper baskets to the slaughtering production line one by one, while using the lifting equipment to continuously lift the remaining baskets. The workers' labor is to repeat a single action continuously, and each basket is filled with poultry, which makes the workers' labor intensity high. Therefore, it is necessary to research and develop a robot that can automatically load the materials. Summary of the invention

[0003] The object of the present invention is to provide a feeding robot for a poultry slaughtering line, which has the effect of transferring a basket to the poultry slaughtering line with a high degree of automation and high efficiency.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A loading robot for a poultry slaughtering assembly line, comprising a frame, a support plate slidably connected to the frame in a vertical direction, a vertical lead screw rotatably connected to the frame, a nut assembly installed on the vertical lead screw, a gear arranged on the vertical lead screw, a pushing assembly and a first conveyor belt device distributed on both sides above the support plate, and a clamping mechanism located above the support plate, a one-way bearing is installed between the gear and the vertical lead screw, the pushing assembly comprises a pushing hydraulic cylinder, a pushing seat fixed to the piston rod of the pushing hydraulic cylinder, a guide seat fixed to the pushing seat, and a rack fixed to the guide seat, the rack is meshed with the gear, the clamping mechanism is provided with a guide hole, the guide seat passes through the guide hole, and when the pushing seat is close to the first conveyor belt device, the guide seat drives the clamping mechanism to rise.

[0005] By adopting the above technical solution, the basket used for the turnover of poultry is narrow at the top and bottom and wide in the middle, similar to the shape of a gold ingot, with a protruding convex part in the middle and an openable door on the top, which can be used to take the poultry out of the basket. Multiple baskets are stacked up and down in sequence to form a stack, with a groove on the top of the basket and a boss on the bottom of the basket. The boss on the bottom of the upper basket is embedded in the groove on the top of the lower basket, which plays a positioning role and prevents the upper and lower baskets from being misaligned or tipped over.

[0006] Working principle: A stack of baskets is placed on a pallet, the clamp mechanism clamps the top basket, and the push seat is aligned with the side of the top basket. The push hydraulic cylinder drives the push seat to move toward the top basket, and the guide seat moves with the push seat and guides the clamp mechanism to rise, so that the basket clamped by the clamp mechanism rises, and the boss at the bottom of the basket is separated from the groove at the top of the lower basket. The push seat contacts and pushes the basket, pushing the basket from the clamp mechanism to the first conveyor belt device, and the first conveyor belt device transports the basket forward to complete the loading operation.

[0007] When the push seat approaches and pushes the basket, the rack moves with the push seat and the guide seat and drives the gear to rotate. Since a one-way bearing is installed between the gear and the vertical screw, the rotation of the gear will not drive the vertical screw to rotate. The push seat pushes the basket to the first transmission device and then moves back. At this time, the rack connected to the guide seat drives the gear to rotate. The gear drives the vertical screw to rotate through the one-way bearing. The vertical screw drives the nut assembly and the pallet to rise. The topmost basket among the remaining baskets on the pallet rises between the push seat and the first conveyor belt device. At this time, the piston rod of the push hydraulic cylinder extends again and the material is loaded again. This reciprocating process loads the baskets on the pallet one by one onto the first conveyor belt device.

[0008] The present invention is further configured as follows: it also includes a linkage mechanism, the first conveyor belt device includes a first rotating shaft, the linkage mechanism includes a linkage shaft linked to the first rotating shaft, a first friction wheel fixed to the linkage shaft, a second friction wheel fixed to the vertical screw, an adjusting hydraulic cylinder installed on the frame, a mounting seat installed on the piston rod of the adjusting hydraulic cylinder, and a third friction wheel installed on the mounting seat, the piston rod of the adjusting hydraulic cylinder extends to drive the third friction wheel to press against the first friction wheel and the second friction wheel at the same time.

[0009] By adopting the above technical solution, when all the baskets on the pallet are pushed to the first conveyor belt device, the piston rod of the regulating hydraulic cylinder is extended to drive the third friction wheel to press against the first friction wheel and the second friction wheel at the same time, and the rotational power of the first rotating shaft in the first conveyor belt device is transmitted to the vertical screw through the linkage shaft, the first friction wheel, the third friction wheel, and the second friction wheel in sequence, and the rotating vertical screw drives the nut assembly and the pallet to descend until the pallet moves to the lowest position of the stroke, and then the piston rod of the regulating hydraulic cylinder is retracted to drive the third friction wheel to leave the first friction wheel and the second friction wheel. It should be pointed out in particular that due to the presence of the one-way bearing, the rotating vertical screw in this process will not drive the gear to rotate.

[0010] The present invention is further configured as follows: the clamping mechanism includes a top seat, two side plates fixed on both sides of the top seat, a stop seat fixed at the lower end of the side plate, a claw plate hinged to the side plate, and a spring driving the claw plate to press against the stop seat, and the claw plate is in an inclined state when pressing against the stop seat.

[0011] By adopting the above technical solution, when the clamp mechanism descends, the claw plate contacts the frame, and the spring force drives the upper end of the claw plate to always stick to the outer wall of the frame, until the clamp mechanism moves to the lowest end of the stroke, and the upper end of the claw plate just touches the convex part in the middle of the frame, and when the clamp mechanism rises under the guidance of the guide seat, the upper ends of the two claw plates in the clamp mechanism can hold the convex part in the middle of the frame to make the frame rise, so that the boss at the bottom of the frame is separated from the groove at the upper end of the lower frame. The push seat contacts and pushes the frame, so that the frame leaves between the two claw plates and enters the first conveyor belt device.

[0012] The present invention is further configured as follows: the frame is provided with four vertical guide columns, the top seat is provided with four through holes, the guide columns pass downward through the through holes, and a limit seat is provided at the lower end of the guide column.

[0013] By adopting the above technical solution, the cooperation of the four guide posts and the four through holes enables the clamping mechanism to be raised and lowered smoothly. When the top seat in the clamping mechanism abuts against the limit seat during the descending process, it indicates that the clamping mechanism has moved to the lowest point of the stroke.

[0014] The present invention is further configured as follows: it also includes a vertical cylinder body, a vertical piston installed in the vertical cylinder body, a vertical rod fixed to the vertical piston, a horizontal cylinder body, a horizontal piston installed in the horizontal cylinder body, and a horizontal rod fixed to the horizontal piston, the lower end of the vertical rod abuts against the upper end of the top seat, the horizontal rod is fixed to the guide seat, the vertical cylinder body is connected to the horizontal cylinder body through a pipeline, and the vertical cylinder body, the horizontal cylinder body, and the pipeline are filled with a medium.

[0015] By adopting the above technical solution, since the rise of the clamping mechanism is achieved through the guiding effect of the guide seat, the upper end of the inner wall of the guide hole in the clamping mechanism is always in contact with the guide seat, but there is a gap between the lower end of the inner wall of the guide hole and the guide seat, which causes the clamping mechanism to rely more on its own weight when descending. However, if the weight of the clamping mechanism itself is large, it will require the push hydraulic cylinder and the push seat to be subject to greater resistance during movement, affecting the stability of the pushing action. If the weight of the clamping mechanism itself is small, it is difficult to ensure that the clamping mechanism can quickly move to the lowest end of the stroke.

[0016] The present invention is equipped with a vertical cylinder, a vertical piston, a horizontal cylinder, and a transverse piston. When the push seat approaches and pushes the basket in the clamping mechanism, the push seat drives the horizontal piston to move through the guide seat and the horizontal rod, and the medium pressure in the vertical cylinder and the horizontal cylinder is reduced, thereby reducing the force of the vertical rod on the clamping mechanism during the ascending process. When the push seat pushes the basket to the first conveyor belt device and then returns, the transverse rod moves with the guide seat and drives the transverse piston to pressurize the medium. The vertical piston in the vertical cylinder moves downward after being stressed, and the clamping mechanism is pressed down by the vertical rod to make the clamping mechanism move downward quickly to the lowest point of the stroke, which can not only ensure that the clamping mechanism descends to the designed position, but also help to improve the rhythm of feeding.

[0017] The present invention is further configured as follows: it includes a base, the base is provided with a receiving slot, the receiving slot is used for the pallet to enter, a basket entry channel is provided above the base, a second conveyor belt device is provided at the bottom of the basket entry channel, baffles are distributed on both sides of the basket entry channel, a clamping frame is slidably connected to the baffle, a horizontal driving component for pushing the clamping frame to slide horizontally is provided on the baffle, the clamping frame is provided with two clamping plates distributed on both sides of the basket entry channel, and a clamping component for driving the two clamping plates to approach or move away from each other.

[0018] By adopting the above technical solution, the second conveyor belt device is used to convey multiple stacks of baskets forward, and the retaining frame is used to prevent the baskets from tipping over. The clamping assembly and the horizontal driving member are used to clamp and transfer a stack of baskets of the second conveyor belt device to the pallet.

[0019] The present invention is further configured as follows: it also includes a control device for controlling the horizontal drive assembly and the adjusting hydraulic cylinder, a pressure sensor is installed in the receiving slot, and the pressure sensor is communicatively connected with the control device.

[0020] By adopting the above technical solution, when the pallet descends to the lowest point of the stroke, the pallet is embedded in the accommodating groove, the upper end of the pallet is flush with the upper end surface of the base, and pressure is generated on the pressure sensor. The pressure sensor transmits the pressure signal to the control device, and the control device controls the horizontal drive assembly and adjusts the action of the hydraulic cylinder.

[0021] The present invention is further configured as follows: the horizontal drive component is a horizontal drive hydraulic cylinder.

[0022] The present invention is further configured as follows: the guide seat is provided with a guide slope, and the guide slope is used to contact the inner wall of the guide hole.

[0023] The present invention is further configured as follows: four sliding blocks are fixed on both sides of the support plate, the frame is provided with four vertically arranged sliding grooves, and the sliding blocks are slidably connected in the sliding grooves.

[0024] The beneficial effects of the present invention are:

[0025] 1. The efficiency of the poultry slaughtering production line is relatively high, and a relatively fast loading speed is required when loading. The loading action of the present invention is mainly that the pushing hydraulic cylinder drives the pushing seat to move, and the pushing seat pushes the basket in the clamping mechanism to the first conveyor belt device. During the return process of the pushing seat, the rack, gear, one-way bearing, and nut assembly drive the support plate to rise, so that the next basket is lifted to the position to be pushed, and the pushing hydraulic cylinder drives the pushing seat to move again to realize continuous loading operation. The loading operation is simple and achieves relatively fast loading efficiency to meet the needs of the poultry slaughtering production line.

[0026] 2. The loading operation of the basket itself is not difficult, and is simple, repetitive, and physically demanding labor. During the implementation, application, and promotion of the present invention, if the production and manufacturing cost of the present invention is high, it will inevitably result in a high sales price, and it does not have an advantage in areas with abundant labor and low labor costs. The loading operation of the loading robot of the present invention mainly relies on the actions of multiple hydraulic cylinders such as the push hydraulic cylinder, the adjustment hydraulic cylinder, and the horizontal drive hydraulic cylinder, and the rising and falling of the pallet are achieved through an ingenious structure. The manufacturing cost is low, which is conducive to the implementation of the present invention and its application and promotion in the industry.

[0027] 3. The present invention cleverly leverages the structure of a rack, gear, one-way bearing, vertical screw and nut assembly to lift the position of the pallet by using the movable push seat. Since the moving distance of the push seat is fixed, the height of the pallet lift can be accurately controlled by setting the technical parameters of the gear, rack and vertical screw. When the pallet needs to be lowered, the power of the first rotating shaft in the first conveyor belt device is leveraged by adjusting the hydraulic cylinder, the first friction wheel, the second friction wheel, the third friction wheel and the linkage shaft structure to lower the pallet into the accommodating slot. The lifting of the pallet does not require an additional power mechanism, which effectively reduces the production and manufacturing cost of the feeding robot.

[0028] 4. The present invention ingeniously uses a hydraulic device composed of a vertical cylinder, a vertical piston, a horizontal cylinder, and a transverse piston. Compared with using a spring to drive the clamping mechanism to descend, the hydraulic device of the present invention can reduce the resistance encountered by the clamping mechanism during the ascending process, and can also drive the clamping mechanism to rest on the limit seat during the descending process, so that it descends to the specified position.

DETAILED DESCRIPTION

[0043] A feeding robot for a poultry slaughtering line, such as Figures 1 to 4 As shown, it includes a frame 1, a base 15, a push assembly 4, a first conveyor belt device 9, and a clamping claw mechanism 5. A loading station is provided between the push assembly 4 and the first conveyor belt device 9. A support plate 2 is provided directly below the loading station. Four sliders 21 are fixed on both sides of the support plate 2. The four sliders 21 are distributed on both sides of the support plate 2 in pairs. Four slide grooves 11 are provided on the frame 1. The slide grooves 11 are arranged in the vertical direction. The four sliders 21 are respectively slidably connected in the four slide grooves 11, so that the support plate 2 can slide on the frame 1 in the vertical direction. A vertical lead screw 3 is provided on the frame 1. The upper and lower ends of the vertical lead screw 3 are installed on the frame 1 through bearings. A nut assembly 31 is installed on the vertical lead screw 3. The nut assembly 31 is fixed to the support plate 2. The rotation of the vertical lead screw 3 can drive the nut assembly 31 and the support plate 2 to rise and fall.

[0044] like Figures 4 to 6 , Fig.10As shown, the pushing assembly 4 includes a pushing hydraulic cylinder 41, a pushing seat 42 fixed to the piston rod of the pushing hydraulic cylinder 41, a guide seat 44 fixed to the pushing seat 42, and a rack 43 fixed to the guide seat 44. A gear 32 is provided on the vertical lead screw 3, and a one-way bearing is installed between the gear 32 and the vertical lead screw 3. The rack 43 is meshed with the gear 32. The first conveyor belt device 9 includes a first rotating shaft 91, a second rotating shaft, a first endless conveyor belt, and a first motor. The first endless conveyor belt is sleeved between the first rotating shaft 91 and the second rotating shaft. The first motor is a reduction motor for driving the first rotating shaft 91 to rotate. The feeding robot of the poultry slaughtering assembly line also includes a linkage mechanism 6, which includes a linkage shaft 64, a first friction wheel 61 fixed to the linkage shaft 64, a second friction wheel 62 fixed to the vertical lead screw 3, an adjusting hydraulic cylinder 65 installed and fixed to the frame 1, a mounting seat 66 installed on the piston rod of the adjusting hydraulic cylinder 65, and a third friction wheel 63 installed on the mounting seat 66. The linkage shaft 64 and the vertical lead screw 3 are both vertically arranged, the first rotating shaft 91 is horizontally arranged, the first rotating shaft 91 is installed with a first bevel gear 92, the linkage shaft 64 is installed with a second bevel gear 641, and the first bevel gear 92 is meshed with the second bevel gear 641. The third friction wheel 63 can rotate on the mounting seat 66. The piston rod of the adjusting hydraulic cylinder 65 extends, and the third friction wheel 63 is pressed against the first friction wheel 61 and the second friction wheel 62 at the same time. The piston rod of the adjusting hydraulic cylinder 65 retracts, and the third friction wheel 63 is separated from the first friction wheel 61 and the second friction wheel 62.

[0045] When the piston rod of the push hydraulic cylinder 41 is extended, the push seat 42 and the guide seat 44 move and drive the rack 43 to move, and the rack 43 moves to drive the gear 32 to rotate. Due to the one-way bearing, the rotating gear 32 cannot drive the vertical screw 3 to rotate. When the piston rod of the push hydraulic cylinder 41 is retracted, the push seat 42 and the guide seat 44 move and drive the rack 43 to move, and the rack 43 moves to drive the gear 32 to rotate. At this time, the rotating gear 32 drives the vertical screw 3 to rotate through the one-way bearing, and the vertical screw 3 drives the nut assembly 31 and the support plate 2 to rise.

[0046] like Figures 6 to 9As shown, the clamping mechanism 5 is located at the loading station, and the clamping mechanism 5 includes a top seat 51, two side plates 52 fixed on both sides of the top seat 51, a stopper 53 fixed at the lower end of the side plate 52, a claw plate 54 hinged on the side plate 52, and a spring 55 driving the claw plate 54 to press against the stopper 53. There are two stoppers 53, corresponding to the two side plates 52 respectively. There are two claw plates 54, corresponding to the two side plates 52 respectively. There are two springs 55, corresponding to the two side plates 52 respectively. One end of the spring 55 is fixed on the side plate 52, and the other end of the spring 55 is fixed on the claw plate 54. The elastic force of the spring 55 drives the claw plate 54 to press against the stopper 53. Four through holes 511 are provided on the top seat 51, and four guide posts 12 are fixed on the frame 1. The guide posts 12 are vertically arranged, and the four guide posts 12 correspond to the four through holes 511 respectively. The guide posts 12 pass downward through the through holes 511, and a limit seat 13 is fixed at the lower end of the guide post 12. The cross-section of the limit seat 13 is larger than the cross-section of the through hole 511, so that when the top seat 51 descends to the lower end of the stroke, it will be blocked by the limit seat 13 and will not fall off the guide post 12.

[0047] A guide hole 56 is provided on the top seat 51 in the clamp mechanism 5. The guide seat 44 in the push assembly 4 passes through the guide hole 56. The guide seat 44 is provided with a guide slope 441, and the guide slope 441 contacts the inner wall of the guide hole 56. A vertical cylinder 7 and a horizontal cylinder 8 are also fixed on the frame 1. The vertical cylinder 7 is connected to the horizontal cylinder through a pipe 82. A vertical piston is installed in the vertical cylinder 7, and a horizontal piston is installed in the horizontal cylinder 8. A closed chamber is formed in the vertical cylinder 7, the pipe 82, and the horizontal cylinder 8. The closed chamber is filled with a medium, which is hydraulic oil. A vertical rod 71 is fixed to the vertical piston. The vertical rod 71 is vertically downwardly arranged and its lower end is against the upper end surface of the top seat 51. A horizontal rod 81 is fixed to the horizontal piston. The horizontal rod 81 extends from the horizontal cylinder and is connected to the guide seat 44.

[0048] When the piston rod of the push hydraulic cylinder 41 extends, the push seat 42 drives the guide seat 44 to move, the guide slope 441 on the guide seat 44 guides the top seat 51 to rise, the push seat 42 drives the horizontal rod to move, and the horizontal rod drives the horizontal piston to move, reducing the pressure in the closed chamber. When the piston rod of the push hydraulic cylinder 41 retracts, the guide seat 44 descends under its own gravity and the guidance of the guide slope 441, the push seat 42 drives the horizontal rod to move, and the horizontal rod drives the horizontal piston to move, increasing the pressure in the closed chamber, the vertical piston and the vertical rod 71 descend, and the lower end of the vertical rod 71 presses the top seat 51 downward, so that the lower end surface of the top seat 51 abuts against the limit seat 13.

[0049] like Figure 3 , Fig.11As shown, a receiving slot 151 is provided on the base 15, and the receiving slot 151 is located directly below the pallet 2 for the pallet 2 to enter. A basket entry channel is provided above the base 15, and a second conveyor belt device 10 is provided at the bottom of the basket entry channel. Blocking frames 16 are distributed on both sides of the basket entry channel, and a clamping frame 17 is slidably connected to the blocking frame 16. A horizontal driving component 18 for pushing the clamping frame 17 to slide horizontally is provided on the blocking frame 16. The clamping frame 17 is provided with two clamping plates 171 distributed on both sides of the basket entry channel, and a clamping component 19 for driving the two clamping plates 171 to move closer to or away from each other. The horizontal driving component 18 is a horizontal driving hydraulic cylinder, and the horizontal driving hydraulic cylinder body is mounted and fixed on the blocking frame 16, and its piston rod is fixed to the clamping frame 17. The clamping assembly 19 includes two groups of clamping hydraulic cylinders, each group of clamping hydraulic cylinders includes six clamping hydraulic cylinders, and the two groups of clamping hydraulic cylinders correspond to two clamping plates 171 respectively. The clamping hydraulic cylinder bodies are installed and fixed on the clamping frame 17, and the piston rods of the clamping hydraulic cylinders are fixed to the clamping plates 171.

[0050] like Fig.12 , Fig.13 As shown, the basket 22 for circulating poultry is narrow at the top and bottom and wide in the middle, similar to a gold ingot shape, with a protruding convex portion 223 in the middle and an openable door on the top, which can be opened to take the poultry out of the basket 22. Multiple baskets 22 are stacked up and down in sequence to form a stack, with a groove 221 on the top of the basket 22 and a boss 222 on the bottom of the basket 22. The boss 222 at the bottom of the upper basket 22 is embedded in the groove 221 at the top of the lower basket 22, which plays a positioning role to prevent the upper and lower baskets 22 from being misplaced or tipping over.

[0051] Working principle: A stack of baskets 22 is placed on the pallet 2, the clamp mechanism 5 clamps the top basket 22, and the push seat 42 is aligned with the side of the top basket 22. The push hydraulic cylinder 41 drives the push seat 42 to move toward the top basket 22, and the guide seat 44 moves with the push seat 42 and guides the clamp mechanism 5 to rise, so that the basket 22 clamped by the clamp mechanism 5 rises, and the boss 222 at the bottom of the basket 22 is separated from the groove 221 at the top of the lower basket 22. The push seat 42 contacts and pushes the basket 22, pushing the basket 22 from the clamp mechanism 5 to the first conveyor belt device 9, and the first conveyor belt device 9 conveys the basket 22 forward to complete the loading operation.

[0052] When the push seat 42 approaches and pushes the basket 22, the rack 43 moves with the push seat 42 and the guide seat 44 and drives the gear 32 to rotate. Since a one-way bearing is installed between the gear 32 and the vertical screw 3, the rotation of the gear 32 will not drive the vertical screw 3 to rotate. The push seat 42 pushes the basket 22 to the first transmission device and then moves back. At this time, the rack 43 connected to the guide seat 44 drives the gear 32 to rotate. The gear 32 drives the vertical screw 3 to rotate through the one-way bearing. The vertical screw 3 drives the nut assembly 31 and the pallet 2 to rise. The topmost basket 22 among the remaining baskets 22 on the pallet 2 rises between the push seat 42 and the first conveyor belt device 9. At this time, the piston rod of the push hydraulic cylinder 41 extends again, and the material is loaded again. This reciprocating process loads the baskets 22 on the pallet 2 onto the first conveyor belt device 9 one by one.

[0053] When all the baskets 22 on the pallet 2 are pushed to the first conveyor belt device 9, the piston rod of the regulating hydraulic cylinder 65 extends out, driving the third friction wheel 63 to press against the first friction wheel 61 and the second friction wheel 62 at the same time, and the rotational power of the first rotating shaft 91 in the first conveyor belt device 9 is transmitted to the vertical screw 3 through the linkage shaft 64, the first friction wheel 61, the third friction wheel 63, and the second friction wheel 62 in sequence, and the rotating vertical screw 3 drives the nut assembly 31 and the pallet 2 to descend until the pallet 2 moves to the lowest position of the stroke, and the piston rod of the regulating hydraulic cylinder 65 retracts, driving the third friction wheel 63 to leave the first friction wheel 61 and the second friction wheel 62. It should be pointed out that due to the presence of the one-way bearing, the rotating vertical screw 3 in this process will not drive the gear 32 to rotate.
