Description

Technical Field

[0001] The present invention belongs to the field of egg feeding, and specifically relates to an egg grading and detecting feeding device. Background Art

[0002] When industrially processing eggs, it is necessary to judge the quality of eggs and screen eggs with different appearance qualities, so as to realize the grading and detection of eggs. The commonly used detection method is to use the light penetration method to detect eggs. In a dim environment, eggs are conveyed to a corresponding light source through a conveyor belt. The light source irradiates the blunt end (big end) of the egg, and a monitoring camera is used to observe the shape and size of the air chamber boundary of the egg, and records are made according to the conveying order and quality of the eggs and feeding is carried out to the rear end, thereby realizing the grading and detection feeding of eggs.

[0003] The existing feeding device for egg grading and detection requires manual placement of the blunt end of the egg upward in a fixed container on the surface of the conveyor belt. Since there are too many eggs to be detected, the staff is prone to fatigue and accidentally place the pointed end of the egg upward when placing the egg in the container. As a result, when the egg is conveyed to the detection device, the light source is close to the pointed end of the egg for irradiation and is observed by the monitoring camera, so that the complete shape of the air chamber at the blunt end (big end) cannot be effectively observed, resulting in errors in the judgment of the size and shape of the air chamber. And because the boundary of the air chamber is blurred or presents an irregular projection, it may be misjudged as a deformed or spoiled egg. If the egg is a fertilized egg, the light transmission at the pointed end may cover the typical characteristics of embryo development (such as the vascular network structure), and only show a blurred shadow of the egg yolk. Unfertilized eggs may be misjudged as abnormal air chambers or the presence of foreign objects due to the wrong light source direction, which is not conducive to use.

[0004] Therefore, the present invention provides an egg grading and detecting feeding device. Summary of the Invention

[0010] Preferably, the gear block is slidably connected to the inner wall of the fixing seat, and the output end of the hydraulic cylinder passes through the fixing seat and is fixed to the surface of one end of the movable plate.

[0011] Preferably, the flip support assembly also includes a blowing component, which includes an air cylinder fixed on the outer circumference of the rotating cylinder at both ends of a spring telescopic rod located in adjacent positions, a piston rod slidably inserted in the inner cavity of the air cylinder, an air inlet pipe connected and fixed to one end of the piston rod, a connecting pipe connected and fixed to one side of the air cylinder, and a one-way valve fixed to the inner cavity of the air inlet pipe and the connecting pipe.

[0012] Preferably, one side of the piston rod extends out of the air cylinder and is fixed to the surface of the connecting plate at the adjacent position, and the connecting pipe is fixedly connected to the inner wall of the rotating cylinder at the adjacent position.

[0013] Preferably, the blowing component further comprises arc tubes arranged at both ends of the inner cavity of the rotating cylinder and a plurality of air outlet pipes evenly connected and fixed at one side of the arc tube, and the connecting pipe is connected and fixed to the arc tube.

[0014] Preferably, the positioning component includes a motor fixed to one end of the fixed seat, an opening penetrating through the middle position of the top of the fixed seat, a circular gear fixedly sleeved on the output end of the motor extending into the opening, racks meshed on both sides of the fixed seat, a mounting plate arranged at the bottom of one of the racks, a baffle plate fixed to the bottom of one side of the other rack and arranged in an L shape, and a connecting component acting on the mounting plate.

[0018] 2. The positioning component of the present invention can position the egg directly below the irradiation lamp and can adjust the distance between the mounting plate and the egg to adapt to eggs with different eggshell light transmittances. For the turbid area of spoiled eggs, abnormal overall shadows can be found by long-distance irradiation, and the characteristics of turbid diffusion can be observed at close range. Adjusting the distance between the irradiation lamp and the egg improves the applicability of the detection, and when the light source is 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.

DETAILED DESCRIPTION

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

[0030] Embodiment 1:

[0031] like Figures 1 to 8 As shown, an egg grading detection and feeding device according to an embodiment of the present invention comprises two bases 1, a conveyor belt body 2 installed between the two bases 1, a plurality of mounting seats 4 evenly fixed on the outer surface of the conveyor belt body 2, a rotating cylinder 5 arranged at the middle position 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 of 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 seat 4, a fixing seat 3 fixed on the top of the two bases 1, cameras 22 fixed at both ends of the inner surface of the fixing seat 3, an irradiation lamp 32 arranged on the top of the two cameras 22, a flip support component acting on the rotating cylinder 5, and a positioning component arranged inside the fixing seat 3. One side of the threaded rod 6 extends to the inner cavity of the threaded groove 7 at the adjacent position and is threadedly connected with the inner wall of the threaded groove 7. The rotating cylinder 5 is a transparent material component;

[0033] When the staff places the eggs one by one into the rotating drum 5 and they are supported in the inner cavity of the rotating drum 5 by the flipping 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 upward, one of the threaded rods 6 can be rotated 180 degrees by the flipping support assembly, thereby driving the rotating drum 5 to flip 180 degrees, and in this process, the flipping support assembly limits the eggs so that they will not escape from the inside of the rotating drum 5 during the flipping process, so that the eggs can be adjusted to a state with the blunt end facing upward, and under the action of the positioning assembly, the irradiation lamp 32 is close to the eggs and irradiates downward from the blunt end, and cooperates with the camera 22 to observe the quality of the eggs, thereby preventing the irradiation lamp 32 from irradiating downward from the tip of the egg due to mistakes made by the staff, thereby avoiding the inability to effectively observe the complete form 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 a connecting plate 10 arranged at both ends of the upper and lower 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 arranged in an inclined surface;

[0035] When the positioning plate 11 does not interfere with the abutment plate 9, one side of the positioning plate 11 will extend to the upper and lower ends of the inner cavity of the rotating cylinder 5. Therefore, after the egg is placed in the inner cavity of the rotating cylinder 5, the inner cavity size of the rotating cylinder 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 cylinder 5, causing its blunt end to face downward, the two threaded rods 6 are rotated by the rotation drive assembly. Due to the limiting effect of the threaded connection arrangement of the threaded rod 6 and the threaded groove 7, the rotating cylinder 5 is in a stable state when the rotating cylinder 5 rotates to any angle, so that the rotating cylinder 5 will flip 180 degrees. When the egg is in the rotating cylinder 5, 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 being separated 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, so as to move 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, so as to further ensure the accuracy of the detection.

[0036] like Figures 1 to 8 As shown, the driving component includes a half gear 20 fixedly sleeved on the surface of one of the threaded rods 6, a hydraulic cylinder 27 fixed to the inner surface of the fixing seat 3 at a position on one side of one of the cameras 22, a movable plate 26 arranged 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 seat 3, and the output end of the hydraulic cylinder 27 passes through the fixing seat 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 started to enable the movable plate 26 to move horizontally along the front-rear 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 circular gear 30, one of the threaded rods 6 can rotate one hundred and eighty degrees, and under the action of the half gear 20, when the rotating drum 5 rotates, the output end of the hydraulic cylinder 27 is controlled to shrink inward so that the baffle 28 will not continue to rotate when it is reset, and when the rotating drum 5 is rotated 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 in a vertical position.

[0038] like Figures 1 to 8As shown, the flipping support assembly further includes a blowing component. The blowing component includes an air cylinder 13 fixed to the outer peripheral surface of the rotating cylinder 5 at both ends of the spring telescopic rod 12 at adjacent positions, a piston rod 15 slidably inserted into the inner cavity of the air cylinder 13, an air inlet pipe 14 fixedly connected to one end of the piston rod 15, a connecting pipe 17 fixedly connected to one side of the air cylinder 13, and a one-way valve 18 fixedly installed in 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 penetrate the inner wall of the adjacent rotating cylinder 5;

[0039] Due to the setting of the one-way valve 18, only gas can be transported from the outside to the inner cavity of the air cylinder 13 at the air inlet pipe 14, and the gas in the inner cavity of the air cylinder 13 cannot be transported to the outside of the air cylinder 13. Only gas can be transported from the air cylinder 13 to the inner cavity of the connecting pipe 17 at the connecting pipe 17, and the gas in the inner cavity of the connecting pipe 17 cannot flow into the inner cavity of the air cylinder 13. Thus, during the process that the positioning plate 11 abuts against the adjacent abutting plate 9, the connecting plate 10 moves towards the direction close to the rotating cylinder 5, so that the piston rod 15 moves towards the direction close to the rotating cylinder 5, so that the air pressure in the inner cavity of the air cylinder 13 changes, so that the gas in the inner cavity of the air cylinder 13 can be transported into the inside of the connecting pipe 17. And when the positioning plate 11 moves away from the adjacent abutting plate 9 and the connecting plate 10 is reset under the action of the resilience of the adjacent spring telescopic rod 12, the piston rod 15 can move away from the direction of the rotating cylinder 5, so that the air pressure in the inner cavity of the air cylinder 13 changes again, so that the outside gas can enter the inner cavity of the air cylinder 13.

[0040] As Figures 1 to 8 shown, the blowing component further includes arc pipes 16 arranged at both sides of the upper and lower ends inside the rotating cylinder 5 and a plurality of air outlet pipes 19 uniformly and fixedly connected to one side of the arc pipes 16. The connecting pipe 17 is fixedly connected and communicated with the arc pipes 16;

[0041] Under the conduction of the connecting pipe 17, the gas transported from the air cylinder 13 enters the inner cavity of the arc pipes 16 and is discharged from the plurality of air outlet pipes 19, blowing air towards the surface of the egg so that the air flow enters the interior through the eggshell pores. Thus, when the irradiation lamp 32 irradiates, if the air chamber shape 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 detection accuracy.

[0042] Embodiment 2:

[0043] In the above method, although the problem that the staff is prone to fatigue and place the eggs with the tips facing up when placing the eggs in the container, which affects the accuracy of egg detection, is solved. However, in practice, when the conveyor belt body 2 conveys the eggs to the middle position of the fixed seat 3, it is easy that the eggs do not stay directly below the irradiation lamp 32, and most of the irradiation lamps 32 are set constantly and cannot adjust the distance between the irradiation lamp 32 and the eggs to adapt to eggs with different eggshell light transmittances.

[0044] Therefore, as Figures 1 to 8 shown, compared with the first embodiment, another embodiment of the present invention is as follows:

[0045] The positioning component includes a motor 21 fixed to one end of the fixed seat 3, an opening 23 penetrating through the middle position of the top of the fixed seat 3, a circular gear 30 fixedly sleeved on the output end of the motor 21 and extending into the opening 23, racks 24 meshed on both sides of the fixed seat 3, a mounting plate 31 arranged at the bottom of one of the racks 24, a baffle 28 fixed to the bottom of one side of the other rack 24 and arranged in an L shape, and a connecting component acting on the mounting plate 31. The irradiation lamp 32 is fixed to the mounting plate 31, and the racks 24 are slidably connected to the inner wall of the opening 23;

[0046] When the mounting seat 4 moves along with the conveyor belt body 2 until it moves to the middle position at the bottom of the fixed seat 3, the surface of the rotating cylinder 5 abuts against the baffle 28, so that the rotating cylinder 5 can be positioned, so that the eggs located inside the rotating cylinder 5 are directly below the irradiation lamp 32, so that the rotating cylinder 5 can be positioned. At this time, the conveyor belt body 2 is turned off, and the motor 21 is started to make the circular gear 30 rotate, so that the circular gear 30 rotates and meshes 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 light transmittances. And for the turbid area of the spoiled eggs, the overall shadow abnormality can be found by long-distance irradiation, and the turbid diffusion characteristics can be observed at close range. By adjusting the distance between the irradiation lamp 32 and the eggs, the applicability of the detection is improved, and when the light source is from far to near, the brightness change at the edge of the air chamber is easier to capture, avoiding misjudgment of the air chamber size, which is beneficial to the observation of the camera 22. When the detection is completed, the conveyor belt body 2 is started to make the detected mounting seat 4 move to the rear end of the fixed seat 3, and then the motor 21 is started to make the conveying end rotate in the reverse 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] As 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 peripheral 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 through the damper 34 and the connecting spring 25. Thus, when the irradiation lamp 32 needs to be fully in contact with the blunt end of the egg, the elastic pressure of the connecting spring 25 makes the irradiation lamp 32 evenly contact the eggshell surface, reducing the interference of external stray light and improving the clarity and stability of the light transmission detection. Moreover, the connecting spring 25 can absorb the accidental impacts that may occur during the operation, thereby reducing the risk of eggshell cracking. The damper 34 can stably support the mounting plate 31.

[0049] The above front, back, left, right, up, and down are all based on the Figure 1 in the accompanying drawings of the specification. Taking the perspective of the person observing as the standard, 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.

[0050] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
