A poultry hatching egg depalletizing and conveying line

Abstract

This utility model belongs to the field of conveyor technology, and particularly relates to a poultry hatching egg depalletizing conveyor line, including a frame and a conveyor line mounted on the frame. Multiple sets of trays are arranged on the conveyor line. An imaging detector is installed at the top center of the frame, and a touch screen and an emergency stop button are installed on the outer wall of the front end of the imaging detector. By installing the imaging detector in the middle of the frame, and installing a hyperspectral camera and multiple sets of illumination rings inside the imaging detector, the multiple sets of illumination rings can provide all-round illumination to the hatching eggs on the trays. The hyperspectral camera combines the illumination to perform non-destructive imaging of the hatching eggs on the trays, effectively identifying surface and internal defects of the hatching eggs. This achieves automated, high-precision, multi-angle hatching egg quality inspection, significantly improving inspection efficiency and accuracy. Furthermore, by installing side barriers on both sides of the bottom of the imaging detector, the two sets of side barriers block external light, reducing the impact of external light on image imaging.

Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a poultry hatching egg unpacking conveyor line. Background Technology

[0002] With the development of large-scale and intensive poultry farming, the processing volume of hatching eggs in large-scale hatcheries has increased dramatically. Taking a large-scale broiler hatchery with a daily hatching capacity of tens of thousands of eggs as an example, a large number of hatching egg trays need to be processed every day. Traditional manual or simple mechanical assistance methods are far from meeting the efficiency and capacity requirements of such a large production scale. Therefore, poultry hatching egg depalletizing and conveying lines are widely used. The existing poultry hatching egg depalletizing and conveying lines can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] In practical use, commercially available poultry hatching egg depalletizing and conveying lines typically employ imaging equipment to effectively monitor egg quality. This equipment uses visual inspection technology to detect surface cracks and damage. However, this method reveals two major problems: First, insufficient accuracy. Traditional imaging equipment struggles to accurately capture minute cracks on the egg surface or hidden damage inside the shell, leading to substandard eggs entering the subsequent hatching process and increasing breeding losses. Second, poor environmental adaptability. The detection effect is significantly affected by lighting conditions. When there are fluctuations in light intensity, light refraction, or shadows around the conveyor line, the image acquisition quality of the imaging equipment drops drastically, increasing detection errors and compromising the reliability of hatching egg screening. Therefore, we propose a new poultry hatching egg depalletizing and conveying line to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a poultry hatching egg unpacking and conveying line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a poultry hatching egg depalletizing and conveying line, comprising a frame and a conveying line mounted on the frame, wherein multiple sets of brackets are provided on the conveying line, an imaging detector is installed at the top center of the frame, a touch screen and an emergency stop button are installed on the outer wall of the front end of the imaging detector, a hyperspectral camera is installed at the top inside the imaging detector, multiple sets of illumination lamp rings are installed at equal intervals on the lower outer side of the inner wall of the imaging detector, side barriers are installed on both sides of the bottom end of the imaging detector, and a lifting assembly is provided in the middle of the conveying line.

[0006] As an improved technical solution, the lifting assembly includes a base plate fixed to the middle of the lower end of the frame, a lifting frame at the top of the base plate, the lifting frame being slidably connected to the base plate via four sets of guide rods, a first linear actuator installed at the bottom of the base plate, the output end of the first linear actuator being connected to the bottom of the lifting frame, mounting seats installed at both the front and rear ends of the lifting frame, a second linear actuator installed at the top of each of the two sets of mounting seats, clamping plates installed at the output ends of each of the two sets of second linear actuators, two sets of slots installed on both the front and rear sides of the bracket, sliding sleeves installed on both sides of the second linear actuators, and the clamping plates being slidably connected to the sliding sleeves via two sets of sliding rods.

[0007] As an improved technical solution, a guide is installed on the left side of the conveyor line.

[0008] As an improved technical solution, the illumination ring is a dimmable LED ring light, whose color temperature and brightness can be adjusted via a touch screen.

[0009] As an improved technical solution, the hyperspectral camera supports multi-band imaging.

[0010] As an improved technical solution, the first linear driver and the second linear driver are servo electric cylinders.

[0011] As an improved technical solution, both sides of the clamping plate are provided with protrusions that match the slots.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] I. This utility model features an imaging detector installed in the middle of the frame, housing a hyperspectral camera and multiple sets of illumination rings. These rings provide omnidirectional illumination of the hatching eggs on the rack, while the hyperspectral camera performs non-destructive imaging of the eggs in conjunction with the illumination. This effectively identifies surface and internal defects in the eggs, achieving automated, high-precision, and multi-angle quality inspection, significantly improving inspection efficiency and accuracy. Furthermore, side barriers installed on both sides of the bottom of the imaging detector block external light, reducing its impact on image imaging.

[0014] II. This utility model features a liftable lifting frame installed in the middle of the frame, with two sets of retractable clamps mounted on two sets of mounting seats on the lifting frame. A first linear drive pushes the lifting frame up and down, while a second linear drive pushes the clamps horizontally. The two sets of clamps precisely clamp the bracket and lift it into the imaging detector, ensuring that the imaging detector can effectively detect the eggs on the bracket and reducing the impact of light on image quality.

[0024] By installing a liftable lifting frame 13 in the middle of the frame 1, and installing two sets of retractable clamping plates 18 on two sets of mounting seats 16 on the lifting frame 13, the first linear driver 14 pushes the lifting frame 13 to move up and down, and the second linear driver 17 pushes the clamping plates 18 to move horizontally, so that the two sets of clamping plates 18 can accurately clamp the bracket 3 and lift the bracket 3 into the imaging detector 4, ensuring that the imaging detector 4 can effectively detect the hatching eggs on the bracket 3 and reduce the influence of light on image quality.

[0025] In other embodiments, a guide 7 is installed on the left side of the conveyor line 2;

[0026] This design allows the guide component 7 to smoothly guide the conveyor line 2 into the detection area, improving conveying stability and reducing detection errors caused by positional deviations.

[0036] Feeding and conveying: The hatching egg tray is driven by the conveyor line 2 and guided by the guide component 7 into the area below the imaging detector 4. Then the system triggers the lifting component to move, causing the second linear driver 17 to push the clamping plate 18 to hold the bracket 3, and then the first linear driver 14 to push the lifting frame 13 to rise, allowing the bracket 3 to enter the lower part of the imaging detector 4.

[0037] Imaging inspection: The hyperspectral camera 8 inside the imaging inspection instrument 4, with the assistance of the uniform illumination ring 9, performs multi-angle and multi-band imaging on the eggs passing through the tray 3 to detect defects such as surface cracks, stains, and abnormal internal air cells.
