Description

Technical Field

[0001] The invention belongs to the field of egg feeding, in particular to an egg grading, detection and feeding device. Background Art

[0002] When industrially processing eggs, it is necessary to judge the quality of the eggs and select eggs of different appearance qualities to achieve egg grading and detection. The commonly used detection method is to detect eggs using light perspective. In a dim environment, the eggs are transported to the corresponding light source via a conveyor belt. The blunt end (big end) of the egg is illuminated by the light source, and the shape and size of the egg's air chamber boundary are observed with the help of a surveillance camera. The order and quality of the eggs are recorded and loaded to the back end, thereby achieving egg grading, detection and loading.

[0003] The existing loading device for egg grading and inspection requires manual placement of eggs with the blunt end facing upward in a container fixed on the conveyor surface. Due to the large number of eggs that need to be inspected, workers are easily fatigued and mistakenly place the eggs with the pointed ends facing upward in the container. As a result, when the eggs are transported to the inspection device, the light source is close to the tip of the egg and is observed by the monitoring camera, making it impossible to effectively observe the complete shape of the blunt end (large end) air cell, resulting in errors in the judgment of the size and shape of the air cell. In addition, due to the blurred or irregular projection of the air cell boundary, the egg may be mistakenly judged as having a deformed air cell or a spoiled egg. If the egg is a fertilized egg, the light transmission through the tip may mask the typical characteristics of embryonic development (such as the vascular network structure), showing only a blurred shadow of the yolk. Unfertilized eggs may be mistakenly judged as having an abnormal air cell or the presence of foreign matter due to the incorrect direction of the light source, which is not conducive to use.

[0004] To this end, the present invention provides an egg grading, detection and feeding device. Summary of the Invention

[0018] 2. The present invention can position the egg directly under the irradiation lamp through the positioning component, and can adjust the distance between the mounting plate and the egg to accommodate eggs with different eggshell translucency. For the turbid area of ​​the spoiled egg, long-distance irradiation can reveal the overall shadow abnormality, and the turbidity diffusion characteristics can be observed at a close distance. Adjusting the distance between the irradiation lamp and the egg improves the applicability of detection. Moreover, when the light source moves from far to near, the light and dark changes at the edge of the air chamber are easier to capture, avoiding misjudgment of the air chamber size, which is beneficial to camera observation.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] Example 1:

[0031] like Figures 1 to 8 As shown, an egg grading detection and loading device according to an embodiment of the present invention comprises two bases 1, a conveyor belt body 2 mounted between the two bases 1, a plurality of mounting seats 4 evenly fixed to the outer surface of the conveyor belt body 2, a rotating cylinder 5 disposed in the middle of the mounting seats 4, and a position adjustment detection mechanism for auxiliary detection;

[0032] The position adjustment detection mechanism includes a threaded rod 6 fixed at the middle position on both sides of the outer circumference of the rotating cylinder 5, a threaded groove 7 opened on both sides of the inner surface of the mounting base 4, a fixing base 3 fixed to the top of the two bases 1, cameras 22 fixed to both ends of the inner surface of the fixing base 3, an irradiation lamp 32 arranged on the top of the two cameras 22, a flip support assembly acting on the rotating cylinder 5, and a positioning assembly arranged inside the fixing base 3. One side of the threaded rod 6 extends into the inner cavity of the adjacent threaded groove 7 and is threadedly connected to the inner wall of the threaded groove 7. The rotating cylinder 5 is made of a transparent material.

[0033] When the staff places the eggs one by one into the interior of the rotating drum 5 and they are supported in the inner cavity of the rotating drum 5 by the flip support assembly, if the conveyor belt body 2 transports the eggs to the position of the camera 22 and the camera 22 observes that the eggs are placed with the tip facing upwards, one of the threaded rods 6 can be rotated one hundred and eighty degrees by the flip support assembly, thereby driving the rotating drum 5 to flip one hundred and eighty degrees. In this process, the flip support assembly limits the eggs so that they will not escape from the interior of the rotating drum 5 during the flipping process, so that the eggs can be adjusted to a state with the blunt end facing upwards, and under the action of the positioning assembly, the irradiation lamp 32 is close to the eggs and irradiates downwards from their blunt ends, and cooperates with the camera 22 to observe the quality of the eggs. In this way, the irradiation lamp 32 will not be irradiated downwards from the tip of the eggs due to mistakes of the staff, thereby avoiding the inability to effectively observe the complete shape of the blunt end air chamber, resulting in errors in the judgment of the size and shape of the air chamber, and the possibility of misjudging the air chamber as deformed or spoiled eggs due to blurred boundaries or irregular projections of the air chamber, thereby ensuring the accuracy of detection.

[0034] like Figures 1 to 8 As shown, the flip support assembly includes connecting plates 10 provided at the upper and lower ends of both sides of the outer circumference of the rotating cylinder 5, two positioning plates 11 fixed to one end of the connecting plate 10, a spring telescopic rod 12 fixed to the side of the connecting plate 10 close to the rotating cylinder 5, a support bar 8 fixed to the top of the mounting seat 4, a contact plate 9 fixed to the bottom of the support bar 8, and a driving component acting on the threaded rod 6. The spring telescopic rod 12 is fixed to the outer circumference of the rotating cylinder 5 at the adjacent position, and one side of the positioning plate 11 is provided with an inclined surface.

[0035] When the positioning plate 11 does not interfere with the interference plate 9, one side of the positioning plate 11 will extend to the upper and lower ends of the inner cavity of the rotating drum 5. Therefore, after the egg is placed in the inner cavity of the rotating drum 5, the inner cavity size of the rotating drum 5 is slightly larger than the size of the egg. When placed, its tip will be placed between the four positioning plates 11 at the bottom for positioning, thereby preventing the egg from shifting. If an error occurs when the egg is placed in the inner cavity of the rotating drum 5, causing its blunt end to face downward, the two threaded rods 6 are rotated by the rotation assembly. Due to the limiting effect of the threaded connection arrangement of the threaded rods 6 and the threaded grooves 7, the rotating drum 5 is in a stable state when it is rotated to any angle, so that the rotating drum 5 will turn 180 degrees. At the same time, the four positioning plates 11 at the top of both sides of the rotating cylinder 5 will be separated from the adjacent contact plates 9, so that the positioning plates 11 will move to the top of the inner cavity of the rotating cylinder 5 under the action of the rebound force of the spring telescopic rod 12, so that the eggs can be blocked from the top of the rotating cylinder 5 to prevent them from escaping from the inner cavity of the rotating cylinder 5 as the rotating cylinder 5 turns 180 degrees. When the two positioning plates 11 originally at the bottom of the rotating cylinder 5 are rotated to face upward, their inclined surfaces will conflict with the contact plates 9, thereby moving away from the inner cavity of the rotating cylinder 5, thereby opening the top of the inner cavity of the rotating cylinder 5, thereby ensuring that the irradiation lamp 32 will not be blocked when irradiating the eggs, thereby further ensuring the accuracy of the detection.

[0036] like Figures 1 to 8 As shown, the driving component includes a half gear 20 fixedly mounted on the surface of one of the threaded rods 6, a hydraulic cylinder 27 fixed to the inner surface of the fixing base 3 at a position on one side of one of the cameras 22, a movable plate 26 provided on the other side of one of the cameras 22, and a plurality of tooth blocks 29 uniformly fixed to one end of the top of the movable plate 26. The tooth blocks 29 are slidably connected to the inner wall of the fixing base 3. The output end of the hydraulic cylinder 27 passes through the fixing base 3 and is fixed to the surface of one end of the movable plate 26.

[0037] When the camera 22 observes that the egg moving between the two cameras 22 is in a state with the tip facing upward, the hydraulic cylinder 27 is activated to enable the movable plate 26 to move horizontally in the front-to-back direction, and the movable range of the movable plate 26 is controlled, so that under the meshing action between the half gear 20 and the movable plate 26, one of the threaded rods 6 can rotate one hundred and eighty degrees. Under the action of the half gear 20, after the rotating drum 5 rotates, the output end of the hydraulic cylinder 27 is controlled to retract inward so that the baffle 28 will not be reset when the rotating drum 5 continues to rotate. When the rotated rotating drum 5 is used to place the egg again, the staff needs to rotate the angle of the rotating drum 5 so that the half gear 20 faces the hydraulic cylinder 27 and the rotating drum 5 is placed vertically.

[0038] like Figures 1 to 8As shown, the flip support assembly also includes a blowing component, which includes an air cylinder 13 fixed to the outer circumference of the rotating cylinder 5 at both ends of the spring telescopic rod 12 at adjacent positions, a piston rod 15 slidably inserted in the inner cavity of the air cylinder 13, an air inlet pipe 14 connected to one end of the piston rod 15, a connecting pipe 17 connected to one side of the air cylinder 13, and a one-way valve 18 fixed to the inner cavities of the air inlet pipe 14 and the connecting pipe 17. One side of the piston rod 15 extends out of the air cylinder 13 and is fixed to the surface of the adjacent connecting plate 10. The connecting pipe 17 is fixedly connected to the inner wall of the rotating cylinder 5 at the adjacent position.

[0039] Due to the setting of the one-way valve 18, the air inlet pipe 14 can only transport gas from the outside to the inner cavity of the air cylinder 13, while the gas in the inner cavity of the air cylinder 13 cannot be transported to the outside of the air cylinder 13. The connecting pipe 17 can only transport gas from the air cylinder 13 to the inner cavity of the connecting pipe 17, while the gas in the inner cavity of the connecting pipe 17 cannot flow into the inner cavity of the air cylinder 13. Therefore, in the process of the positioning plate 11 conflicting with the adjacent position contact plate 9, the connecting plate 10 moves in the direction close to the rotating cylinder 5, thereby causing the piston rod 15 to move in the direction close to the rotating cylinder 5, thereby causing the air pressure in the inner cavity of the air cylinder 13 to change, thereby allowing the gas in the inner cavity of the air cylinder 13 to be transported to the inside of the connecting pipe 17, and when the positioning plate 11 moves away from the adjacent position contact plate 9 so that the connecting plate 10 is reset under the action of the rebound force of the adjacent position spring telescopic rod 12, the piston rod 15 can move in the direction away from the rotating cylinder 5, thereby causing the air pressure in the inner cavity of the air cylinder 13 to change again, thereby allowing external gas to enter the inner cavity of the air cylinder 13.

[0040] like Figures 1 to 8 As shown, the blowing component also includes arc tubes 16 provided at both ends of the inner cavity of the rotating cylinder 5 and multiple air outlet pipes 19 evenly connected and fixed at one side of the arc tube 16. The connecting pipe 17 is connected and fixed to the arc tube 16.

[0041] The gas delivered by the gas cylinder 13 enters the inner cavity of the arc tube 16 through the conduction effect of the connecting tube 17 and is discharged from multiple outlet pipes 19, blowing air onto the surface of the egg so that the air flow enters the interior through the pores of the eggshell. Therefore, when the irradiation lamp 32 is irradiated, if the shape of the air chamber expands rapidly or is difficult to recover, it indicates that the pores are blocked or the eggshell calcification layer is abnormal, thereby further improving the accuracy of the detection.

[0042] Example 2:

[0043] Although the above method solves the problem that workers are easily fatigued and mistakenly place the pointed ends of the eggs upwards when placing the eggs in the container, which affects the accuracy of egg detection, from a practical point of view, when the conveyor belt body 2 transports the eggs to the middle position of the fixed seat 3, it is easy for the conveyor belt body 2 to not stop directly under the irradiation lamp 32, and the irradiation lamp 32 is mostly set at a fixed position, and the distance between the irradiation lamp 32 and the eggs cannot be adjusted to accommodate eggs with different eggshell transmittance.

[0044] Therefore Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0045] The positioning assembly includes a motor 21 fixed to one end of the fixing base 3, an opening 23 extending through the middle of the top of the fixing base 3, a circular gear 30 fixedly mounted on the output end of the motor 21 and extending into the interior of the opening 23, racks 24 meshingly arranged on both sides of the fixing base 3, a mounting plate 31 disposed at the bottom of one of the racks 24, an L-shaped baffle 28 fixed to the bottom of one side of the other rack 24, and a connecting member acting on the mounting plate 31. The irradiation lamp 32 is fixed to the mounting plate 31, and the rack 24 is slidably connected to the inner wall of the opening 23.

[0046] When the mounting seat 4 moves with the conveyor belt body 2 until it moves to the middle position of the bottom of the fixed seat 3, the surface of the rotating drum 5 is in conflict with the baffle 28, so that the rotating drum 5 can be positioned, so that the eggs inside the rotating drum 5 are located directly under the irradiation lamp 32, so that the rotating drum 5 can be positioned. At this time, the conveyor belt body 2 is closed, and the circular gear 30 is rotated by starting the motor 21, so that the circular gear 30 rotates and engages with the two racks 24, so that the baffle 28 moves vertically upward, and the mounting plate 31 drives the irradiation lamp 32 to move vertically downward under the action of the connecting component, so that the distance between the mounting plate 31 and the eggs can be adjusted. To adapt to eggs with different eggshell translucency, and for the turbid areas of spoiled eggs, long-distance illumination can reveal overall shadow abnormalities, and close-range turbidity diffusion characteristics can be observed. The applicability of detection is improved by adjusting the distance between the irradiation lamp 32 and the eggs, and when the light source moves from far to near, the light and dark changes at the edge of the air chamber are easier to capture, avoiding misjudgment of the size of the air chamber, which is beneficial to the observation of the camera 22. When the detection is completed, the conveyor belt body 2 is turned on to move the detected mounting seat 4 to the rear end of the fixed seat 3, and then the motor 21 is started to rotate the conveying end in the opposite direction, so that the irradiation lamp 32 moves vertically upward and the baffle 28 moves vertically downward, so that the baffle 28 can position the next mounting seat 4.

[0047] like Figures 1 to 8As shown, the connecting component includes a bottom groove 33 formed at the bottom of one of the racks 24, a damper 34 fixed to the inner wall of the bottom groove 33, and a connecting spring 25 sleeved on the bottom of the outer circumferential surface of the damper 34. The bottom of the damper 34 is fixed to the surface of the mounting plate 31, one end of the connecting spring 25 is fixed to the surface of the mounting plate 31, and the other end of the connecting spring 25 is fixed to the surface of the damper 34.

[0048] The mounting plate 31 and the rack 24 are connected via a damper 34 and a connecting spring 25. Thus, when the irradiation lamp 32 needs to be completely in contact with the blunt end of the egg, the elastic pressure of the connecting spring 25 allows the irradiation lamp 32 to evenly contact the surface of the eggshell, thereby reducing external stray light interference and improving the clarity and stability of light transmission detection. In addition, the connecting spring 25 can absorb accidental impacts that may occur during operation, thereby reducing the risk of eggshell breakage. The damper 34 can stably support the mounting plate 31.

[0049] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
