Description

Technical Field

[0001] This utility model relates to the field of egg sorting technology, and in particular to an automatic egg loading machine. Background Technology

[0002] In the large-scale production and processing of eggs, loading bulk eggs into egg trays is a key link between production and distribution. Existing egg loading machines mostly rely on simple conveying channels to transfer eggs, lacking a targeted posture calibration structure. During the conveying process, eggs are prone to problems such as different orientations of the large end or lying on their sides, which leads to positioning deviations when the suction cup loading machine grabs them. This not only requires manual adjustment of the posture, but also easily causes eggshell damage due to collisions. Utility Model Content

[0003] The purpose of this invention is to provide an automatic egg-filling machine to solve the technical problem of low efficiency in the prior art.

[0004] To solve the above problems, the automatic egg-filling machine involved in this utility model adopts the following technical solution: This utility model provides an automatic egg loading machine, including a suction cup loading machine, and a conveying and sorting device, a sorting device, and an egg tray conveyor arranged sequentially along the egg conveying direction. The conveying and sorting device includes a first conveyor and a sorting device set on the first conveyor. The output end of the sorting device is connected to the input end of the sorting device. The conveying and sorting device sorts the eggs from a disordered state into multiple orderly rows and sends them into the sorting device. Any output port of the sorting device is set to correspond one-to-one with any row of the egg tray conveyor. The conveying path of the egg tray conveyor corresponds to the gripping area of ​​the suction cup loading machine, so that the suction cup loading machine grips the eggs on it and puts them into the empty egg trays outside.

[0005] Preferably, the sorting device includes a fixed frame fixed to the first conveyor, a movable frame that slides with the first conveyor, guide plates that are equally spaced along the movable frame, and a first transmission mechanism mounted on the fixed frame. The guide plates are perpendicular to the first conveyor and the extension direction of the guide plates is consistent with the conveying direction of the first conveyor. The first transmission mechanism is in transmission cooperation with the movable frame so that the first transmission mechanism works to drive the movable frame to slide back and forth along the conveying direction of the first conveyor.

[0006] Preferably, the egg tray conveyor includes a frame, active rollers and driven rollers spaced apart along the length of the frame, and a circulating conveying assembly wound around the active rollers and driven rollers. Both the active rollers and driven rollers have sprockets on their outer peripheries. The circulating conveying assembly includes a closed-loop chain structure and egg tray units spaced apart along its outer length. The inner side of the closed-loop chain structure has teeth that mesh with the sprockets of the active and driven rollers. The active rollers drive the circulating conveying assembly to circulate around the active and driven rollers through meshing with the closed-loop chain structure. The conveying path of the circulating conveying assembly corresponds to the output end of the sorting device. The upper surface of each egg tray unit has grooves matching the number of output ports of the sorting device, and the grooves of adjacent egg tray units are aligned along the conveying direction. The end of the circulating conveying assembly extends to the gripping area of ​​the suction cup loading machine, so that the sorted eggs fall into the grooves of the egg tray units and are conveyed to the gripping area by the circulating conveying assembly.

[0007] Preferably, the sorting device includes a frame and a rotating drum rotatably mounted on the frame. The rotating drum includes a drum body that rotatably cooperates with the frame and egg-hanging structures disposed on the peripheral wall of the drum body and spaced apart along the axial direction of the drum body. The egg-hanging structures have receiving slots that are equally spaced along the circumferential direction of the peripheral wall of the drum body. Each output column of the sorting device corresponds one-to-one with each egg-hanging structure on the peripheral wall of the rotating drum in spatial position, so that the eggs output from each column of the sorting device can be carried one by one by the corresponding egg-hanging structure through the receiving slot.

[0008] Preferably, any egg-hanging structure includes at least two parallel and spaced-apart egg-hanging plates. Each egg-hanging plate has a receiving groove and is equally spaced along the circumference of the egg-hanging plate. Adjacent egg-hanging structures are separated by partitions that extend along the circumference of the cylinder body and are connected end to end to separate the eggs on adjacent egg-hanging structures.

[0009] Preferably, it also includes an egg-sorting structure disposed between the first conveyor and the sorting device. The output end of the sorting device extends above the egg-sorting structure, and the egg-discharging end of the egg-sorting structure extends downward at an incline toward the sorting device. The egg-discharging end of the egg-sorting structure extends with egg-sorting strips that correspond one-to-one in spatial position to each egg-hanging structure. Each egg-sorting strip is located below its corresponding egg-hanging structure.

The egg outlets of each egg-feeding chute of the egg-feeding mechanism are spatially corresponding to the conveyor columns on the egg tray conveyor. The egg outlet of each egg-feeding chute is located directly above the groove of the egg tray unit of its corresponding conveyor column, and the width of the egg outlet is adapted to the opening width of the groove, so that the eggs output through the egg-feeding chute can fall into the groove of the corresponding egg tray unit.

[0011] Preferably, the egg orientation calibration component includes a rotating shaft rotatably mounted on the egg delivery mechanism and egg-dispensing discs spaced apart along the axial direction of the rotating shaft. The rotating shaft drives the egg-dispensing discs to rotate. Egg-dispensing protrusions are arranged around the inner walls of adjacent egg-dispensing discs. The egg-dispensing calibration gap formed between any two adjacent egg-dispensing discs corresponds one-to-one with the egg outlet of each egg delivery chute of the egg delivery mechanism in spatial position. When the egg moves towards the egg delivery chute through the egg hanging structure, the egg-dispensing protrusions push the egg to adjust its posture within the egg-dispensing calibration gap by abutting against the egg surface.

[0016] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention provides an automatic egg loading machine, as shown in the figure, including a suction cup loading machine 19, a conveying and sorting device, a sorting device and an egg tray conveyor arranged sequentially along the egg conveying direction.

[0018] The conveying and sorting device includes a first conveyor 1 and a sorting device mounted on the first conveyor 1. The output end of the sorting device is connected to the input end of the sorting device. The conveying and sorting device sorts the eggs from a disordered state into multiple orderly rows and sends them into the sorting device for sorting. Any output port of the sorting device is set to correspond one-to-one with any row of the egg tray conveyor. The conveying path of the egg tray conveyor corresponds to the gripping area of ​​the suction cup loading machine, so that the suction cup loading machine can grip the eggs on it and put them into the empty egg tray outside.

[0019] In this embodiment, the first conveyor 1 is a rubber belt conveyor with anti-slip texture on the surface of the belt to prevent the eggs from slipping during transport. Guardrails are provided on both sides of the frame of the first conveyor 1 to prevent the eggs from falling off the edge.

[0020] The sorting device includes a fixed frame 2, a movable frame 3, a guide plate 4, and a first transmission mechanism 5. Both the fixed frame 2 and the movable frame 3 span the belt of the first conveyor 1. The two ends of the fixed frame 2 are fixed to the two sides of the frame of the first conveyor 1 by bolts. The two ends of the movable frame 3 are slidably engaged with the slide rails installed on both sides of the frame of the first conveyor 1 by a slider installed at its end. It can move along the conveying direction of the conveyor. The guide plate 4 is perpendicular to the belt conveying surface of the first conveyor 1 and is evenly distributed along the length of the movable frame 3. The extension direction of the guide plate 4 is consistent with the conveying direction of the first conveyor 1. The adjacent guide plates 4 form an egg sorting channel.

[0021] The first transmission mechanism 5 is mounted on the fixed frame 2. The first transmission mechanism 5 is in transmission cooperation with the movable frame 3 so that the first transmission mechanism 5 works to drive the movable frame 3 to slide back and forth along the conveying direction of the first conveyor 1. In this embodiment, the first transmission mechanism 5 is a motor. A first eccentric wheel is mounted on the output shaft of the first transmission mechanism 5. One end of the output rod is hinged to the first eccentric wheel, and the other end of the output rod is hinged to the movable frame 3. The first transmission mechanism 5 works to drive the movable frame 3 to move back and forth along the conveying direction of the first conveyor 1.

[0022] Furthermore, the sorting device also includes two inclined and symmetrically arranged guide plates 6 on the front side of the guide plate 4 (the starting side of the egg conveying direction), which guide the bulk eggs to automatically enter the egg column channel, reducing manual assistance. The fixed ends of the two guide plates 6 abut against the guardrails on both sides of the frame of the first conveyor 1 and are fixed with bolts, while the free ends extend inclinedly towards the guide plate 4, and finally are flush with the edge of the outermost guide plate 4 on the movable frame 3 on the side (the movable frame 3 moves to the maximum adjustment stroke close to the fixed frame 2). The two guide plates 6 cooperate to form a "trumpet mouth" structure, guiding the bulk eggs to gather from the wide inlet to the narrow outlet.

[0023] The egg tray conveyor is used to receive eggs from the egg feeding chute of the sorting device and transport them to the gripping area of ​​the suction cup loading machine. The egg tray conveyor includes a frame, active rollers and driven rollers that are spaced apart and rotated along the length of the frame, and a circulating conveying assembly wrapped around the active rollers and driven rollers. The active rollers are fitted with sprockets that are spaced apart along the axial direction of the active rollers. The driven rollers are fitted with sprockets that correspond to the positions and number of sprockets on the active rollers. The circulating conveying assembly includes a closed-loop chain structure 11 and an egg tray unit 7. The closed-loop chain structure 11 includes multiple chains that are the same number as the sprockets on the active rollers. Each chain corresponds one-to-one with the sprockets at the same axial position on the active rollers and driven rollers, and is fitted onto the corresponding set of active and driven sprockets for meshing and connection. Furthermore, the inner side of the chain is provided with teeth that mesh with the drive roller and driven roller sprockets, and the cyclic motion is achieved through gear meshing transmission. The egg tray unit 7 is fixed at intervals along the outer side of the chain by bolts, and a single egg tray unit 7 is simultaneously connected to multiple chains arranged in parallel, so that when the multiple chains move synchronously in a cyclic motion, they can drive the egg tray unit 7 to move stably, ensuring the smoothness of egg receiving and conveying. The upper surface of each egg tray unit 7 is provided with grooves that are the same number as the number of egg feeding chutes. The grooves of adjacent egg tray units 7 are aligned along the conveying direction to form a continuous row of carrying channels. The end of the circulating conveying component extends to the gripping area of ​​the suction cup loading machine, so that the sorted eggs fall into the grooves of the egg tray unit 7 and are conveyed to the gripping area by the circulating conveying component.

[0024] The sorting device is used to further sort multiple rows of eggs into rows that match the number of rows in the egg tray slots. It includes a frame, a rotating drum 8 rotatably mounted on the frame, egg hanging structures 9, and partitions 10. The rotating drum 8 is connected to the frame bearings through rotating shafts at both ends and can rotate around its own axis. The rotating drum 8 includes a drum body and egg hanging structures 9 arranged around the circumferential wall of the drum body and spaced apart along the axial direction of the drum body. The number of egg hanging structures 9 is consistent with the number of rows in the sorting device. The egg hanging structures 9 have receiving slots that are equally spaced along the circumferential wall of the drum body. Each output row of the sorting device corresponds one-to-one with each egg hanging structure 9 on the circumferential wall of the rotating drum 8 in spatial position, so that each row of eggs output by the sorting device can be carried one by one by the corresponding egg hanging structure 9 through the receiving slot.

[0025] Furthermore, each set of egg-hanging structures 9 includes at least two parallel and spaced-apart egg-hanging plates. The egg-hanging plates extend circumferentially along the cylinder body and are welded and fixed to the outer wall of the cylinder body. The egg-hanging plates are provided with receiving slots that are equally spaced along the circumferential direction of their outer wall. The receiving slots on the egg-hanging plates in the same set correspond one-to-one in terms of position and number. Each receiving slot can hold one egg. An annular partition 10 is provided between adjacent egg-hanging structures 9. The partition 10 extends circumferentially along the circumferential wall of the cylinder body and closes at both ends to form an independent egg channel, preventing the eggs on adjacent egg-hanging structures 9 from colliding with each other.

[0026] To address the issue of eggs easily deviating from the egg-receiving position after exiting the sorting device, this device also includes an egg-guiding structure 12 as a transitional component. The egg-guiding structure 12 is fixed to the frame between the first conveyor 1 and the sorting device, and is inclined downwards. The output end of the sorting device (the outlet of the egg column channel) extends above the egg-guiding structure 12 and connects with the input end of the sorting device. After exiting the egg column channel, the eggs slide down the egg-guiding structure 12 into the input end of the sorting device. Furthermore, the egg-exiting end of the egg-guiding structure 12 extends downwards towards the sorting device, and the egg-exiting end of the egg-guiding structure 12 extends with egg-guiding strips that correspond one-to-one in spatial position to each egg-hanging structure 9. Each egg-guiding strip is located below its corresponding egg-hanging structure 9. When the receiving tank rotates with the rotating drum 8 to the egg-receiving position, the egg-guiding strips below it can guide the eggs sorted by the sorting device into the receiving tank.

[0027] To transfer the eggs from the egg-hanging structure 9 to the egg tray conveyor and to calibrate the egg posture, this device also includes an egg-feeding mechanism 13 mounted on the frame at the egg outlet of the sorting device. The egg-feeding mechanism 13 includes an egg-feeding body and front forks arranged at lateral intervals on the front side of the egg-feeding body. The egg-feeding body has egg-feeding chutes that correspond one-to-one with the egg-hanging structures 9. The output end of the egg-feeding chutes extends to the top of the egg tray conveyor. The gaps between adjacent egg-hanging plates and partitions 10, and between adjacent egg-hanging plates, correspond one-to-one with the front forks located below them. The front fork is tilted upwards in the direction of rotation. When the rotating drum 8 drives the receiving trough to the egg dispensing position, the eggs slide out of the receiving trough, and the front fork guides the eggs into the egg delivery chute. The egg outlets of each egg delivery chute of the egg delivery mechanism 13 are spatially aligned with the conveyor columns on the egg tray conveyor. The egg outlet of each egg delivery chute is located directly above the groove of the egg tray unit 7 of its corresponding conveyor column, and the width of the egg outlet matches the opening width of the groove, so that the eggs output from the egg delivery chute can fall into the groove of the corresponding egg tray unit 7. Furthermore, a vibration motor is installed at the bottom of the egg delivery mechanism 13.

[0028] The egg orientation calibration component 14 includes a rotating shaft rotatably mounted on the upper side of the egg delivery mechanism 13 via a bracket, egg-dispensing discs spaced apart along the axial direction of the rotating shaft, and a second transmission mechanism (configured as a motor). The second transmission mechanism is connected to the rotary pump transmission and operates to drive the rotating shaft of the egg orientation calibration component 14 to rotate. Egg-dispensing protrusions are provided at equal intervals along the circumference on the inner walls of adjacent egg-dispensing discs, forming an egg-dispensing calibration gap between adjacent egg-dispensing discs. The egg-dispensing calibration gap of the egg orientation calibration component 14 corresponds one-to-one with the input end of the egg delivery chute. When the egg is dispensed from the egg hanging structure 9, it first enters the egg-dispensing calibration gap. The rotating egg-dispensing protrusion contacts the surface of the egg. Since the weight of the larger end of the egg is greater than that of the smaller end, the egg-dispensing protrusion will push the egg to rotate around its own axis until the larger end faces the output direction of the egg delivery chute, thus achieving attitude calibration.

[0029] To address the issue of egg trays not being properly positioned or eggs not being properly placed, an opening and closing mechanism is implemented to control the opening and closing of the egg delivery chute. This mechanism includes a baffle plate, an electromagnetic switch, and a laser limiter. The baffle plate is rotatably mounted at the outlet end of the egg delivery chute via a pin, allowing it to rotate around the pin to open / close the chute. One end of the pin on the baffle plate is hinged to the push rod of the electromagnetic switch, which is fixed to the egg delivery body. The laser limiter is fixed to the frame of the egg tray conveyor via a bracket and is positioned corresponding to the groove of the egg tray unit 7. The laser limiter detects whether the gap between adjacent egg tray units 7 is reached. The laser limiter and the electromagnetic switch are connected via a controller signal. When a gap is detected, the controller energizes the electromagnetic switch, causing the push rod to extend and rotate, opening the egg delivery chute and allowing the eggs to slide down.

[0030] To maintain the calibrated egg posture and prevent it from tipping over during descent, an anti-tipping strip is installed inside the egg delivery chute. The anti-tipping strip is made of silicone, with one end fixed to the inner wall of the egg delivery chute by bolts, and the other end extending towards the chute output end, forming a gap with the chute. When the egg slides down the egg delivery chute, the anti-tipping strip will undergo flexible deformation due to the pressure of the egg, conforming to the surface of the egg to form an elastic limit, restricting the egg from tipping over around an axis perpendicular to the delivery direction, and ensuring a stable posture.

[0031] The suction cup loading machine adopts an existing mature structure (such as a pneumatic suction cup assembly). Its gripping area is connected to the output end of the egg tray conveyor. The frame of the suction cup loading machine is equipped with horizontal and vertical moving modules. The suction cup assembly is installed on the moving modules. When the egg tray conveyor transports the eggs to the gripping area, the suction cup assembly descends and uses negative pressure to adsorb the eggs. Then, the moving module drives the suction cup assembly to move above the empty egg tray. The negative pressure is released, and the eggs fall into the egg tray slots, completing the loading.

[0032] The device also includes a transmission system, which includes a main motor 15, a first rotating rod 16 and a second rotating rod 17 mounted on the frame of the sorting device. The main motor 15 is connected to the first rotating rod 16 via a coupling to provide power to the system. The first rotating rod 16 is equipped with a first right-angle reduction gearbox and a second right-angle reduction gearbox, which are located on opposite sides of the sorting device to realize the splitting and direction conversion of power.

[0033] One end of the rotating drum 8 of the sorting device (the end adjacent to the first right-angle reducer) is connected to the input end of the third right-angle reducer. The output end of the first right-angle reducer is connected to the input end of the third right-angle reducer through the third rotating rod to form a power transmission path, driving the rotating drum 8 to rotate around its own axis.

[0034] The drive roller of the egg tray conveyor is connected to the output end of the fourth right-angle reducer on the side closest to the second right-angle reducer. The output end of the second right-angle reducer is connected to the input end of the fourth right-angle reducer through the second rotating rod 17, which drives the drive roller to rotate, thereby driving the circulating conveying component of the egg tray conveyor to run.

[0035] A second chain disk is mounted on the rotating shaft of the egg orientation calibration component 14, and a first chain disk is mounted on the rotating shaft at the other end of the rotating drum 8 away from the first right-angle reducer. The first chain disk and the second chain disk are connected by meshing chain transmission, so that the egg orientation calibration component 14 rotates synchronously with the rotating drum 8 to achieve timing matching of egg posture calibration.

[0036] The working method of this device is as follows: Disorderly sorting: Loose eggs are poured into the first conveyor 1, and enter the column channel of the sorting device through the "trumpet mouth" guide plate 6, where the eggs are arranged in an orderly manner; Egg connection: The egg slides down the egg strip of the egg structure 12 and falls into the hanging structure 9 of the sorting device; Separate conveying: The rotating drum 8 rotates, and the receiving slots of the egg hanging structure 9 receive eggs one by one, while the partition 10 separates adjacent rows of eggs; Posture calibration and transfer: Rotary drum 8 carries the egg to the egg dispensing station, the front fork introduces the egg into the egg orientation calibration gap, and the egg-pulling protrusion pushes the egg to be calibrated so that the large end faces outward before entering the egg delivery chute; Precise feeding control: When the laser limiter detects that the egg tray unit 7 of the egg tray conveyor is in position, the opening and closing mechanism opens the baffle, and the eggs slide down; Anti-tipping conveyor: Anti-tipping soft strips prevent eggs from turning over, ensuring that eggs fall precisely into the groove of egg tray unit 7; Final loading: The egg tray conveyor transports the eggs to the grabbing area, where the suction cup loading machine picks up the eggs and loads them into the empty outer egg tray, completing one loading cycle.

[0037] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
