Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of poultry egg processing equipment, and in particular to a poultry egg grading and packaging device. Background Technology
[0002] Poultry eggs are a common food in people's daily lives. In the production and sales of poultry eggs, they need to be graded and packaged. At present, many small poultry egg processing plants still use manual methods to grade and package poultry eggs. This method is not only inefficient and labor-intensive, but also makes it difficult to guarantee the accuracy of grading.
[0003] With the development of automation technology, some poultry egg grading equipment has emerged. However, these devices are often single-function, only capable of grading. After grading, the poultry eggs still need to be packaged manually, which cannot achieve the integration of grading and packaging and still has the problem of low efficiency. Therefore, we propose a poultry egg grading and packaging device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a poultry egg grading and packaging device to solve the problems of low efficiency and inability to integrate poultry egg grading and packaging in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a poultry egg grading and packaging device, including a base, a grading frame for grading poultry eggs fixedly connected to the top of the base, a controller fixedly connected to the front side of the grading frame, a grading rod provided on the grading frame, an adjustable grading mechanism provided between the grading rod and the grading frame, two upper industrial cameras fixedly connected to the top of the grading frame, two mounting mechanisms provided on the top of the base, two placement platforms fixedly connected to the top of the base, two limiting frames for limiting and positioning egg trays and a lower industrial camera fixedly connected to the top of the placement platforms, and two support legs fixedly connected between the grading frame and the base.
[0006] A further feature of this invention is that a rubber sleeve is fixedly fitted on the outer side of the grading rod, and a rubber pad is fixedly connected to the inner wall of one side of the grading frame.
[0007] By adopting the above technical solutions, poultry eggs can be cushioned and protected to prevent them from being damaged by collisions.
[0008] A further feature of this invention is as follows: the adjustable grading mechanism includes two slide rails fixedly connected to the top of the grading frame and a housing fixedly connected to the top of the two slide rails. A motor is fixedly connected to the front side of the housing, and a drive shaft is fixedly connected to the output shaft of the motor. Two active bevel gears are fixedly sleeved on the outer side of the drive shaft. A lifting screw is rotatably connected to the upper and lower inner walls of the slide rails. A driven bevel gear is fixedly connected to the top of the lifting screw. The two active bevel gears mesh with their corresponding driven bevel gears. A drive plate is threaded onto the outer side of the lifting screw. A single lifting plate is fixedly connected between the two drive plates. A single hanging plate is fixedly connected between the rubber sleeve and the lifting plate. A high-precision distance sensor is fixedly connected to the bottom of the grading rod, and the high-precision distance sensor is enclosed in the rubber sleeve.
[0009] By adopting the above technical solution, based on the maximum diameter of the poultry egg, motor one is started. Motor one drives the drive shaft and two active bevel gears to rotate synchronously. The two active bevel gears drive the two driven bevel gears and the lifting screw to rotate synchronously. The two lifting screws drive the two drive plates, lifting plates, hanging plates and grading rods to rise and fall. Through the measurement of a high-precision distance sensor, the distance between the rubber sleeve and the bottom inner wall of the grading rack can be accurately measured. When the grading requirement value preset by the controller is reached, the high-precision distance sensor sends a signal to the controller. The controller shuts off motor one and puts the poultry egg into the grading rack from the right side. The poultry egg rolls down to the left along the grading rack. When the maximum diameter of the poultry egg is greater than the distance between the rubber sleeve and the bottom inner wall of the grading rack, it means that the poultry egg meets the requirements. At this time, it is blocked by the grading rod on the right side of the grading rod. Conversely, when the size is not up to standard, it continues to roll down to the left from below the grading rod to the position of the rubber pad.
[0010] A further feature of this invention is that two drive plates are slidably fitted into corresponding slide rails, and the lifting plate is slidably connected between the two slide rails.
[0011] By adopting the above technical solution, it is convenient to guide the lifting plate and the drive plate, making their lifting more stable.
[0012] A further feature of this invention is that the mounting mechanism includes a second motor fixedly connected to the top of the base, a rotating shaft fixedly connected to the output shaft of the second motor, a first cylinder fixedly connected to the top of the rotating shaft, a top plate fixedly connected to the output shaft of the first cylinder, a second cylinder fixedly connected to the top of the top plate, a gripper box fixedly connected to the bottom of the second cylinder, a gripper assembly for gripping poultry eggs provided on the gripper box, the gripper assembly including a third motor fixedly connected to the front side of the gripper box, a bidirectional lead screw fixedly connected to the output shaft of the third motor, two transverse sliding plates threaded on the outer side of the bidirectional lead screw, a connecting plate fixedly connected to the bottom of each of the two transverse sliding plates, a clamping plate fixedly connected to the bottom of the connecting plate, and a pressure sensor fixedly connected to the inner side of the clamping plate.
[0013] By adopting the above technical solution, when the industrial camera detects an egg at the position of the grading rod or rubber pad, motor two is activated in time. Motor two drives the rotating shaft to rotate, so that the clamping plate is above the grading frame. The position of the two clamping plates is adjusted by cylinder one to align them with the egg. Cylinder two drives the two clamping plates to move downward, so that the egg is placed between the two clamping plates. Motor three is activated, which drives the rotation of the bidirectional lead screw. The bidirectional lead screw drives the transverse plate, connecting plate and clamping plate to move closer. The clamping force can be measured by the pressure sensor. If the force is within the acceptable range, the egg can be clamped stably without being too strong and damaging the egg. Finally, the above steps are reversed so that the clamping plate is reset above the corresponding placement platform. The egg tray is placed between the two limit frames. According to the measurement of the industrial camera, the front and rear positions of the clamping plates can be adjusted by motor two, and the lateral position of the clamping plates can be adjusted by cylinder one, so that the clamping plates can clamp the egg to the empty position of the egg tray. When the egg tray is full, the personnel remove it and continue to replace it, thus enabling the grading and packaging of eggs.
[0014] A further feature of this invention is that a rectangular opening is provided at the bottom of the gripper box, and both connecting plates are slidably fitted inside the rectangular opening.
[0015] By adopting the above technical solution, the connecting plate can be guided, making its movement more stable and smooth.
[0016] The beneficial effects of this utility model are: This invention, based on the maximum diameter of the poultry egg, uses a motor to drive the synchronous rotation of the drive shaft and two active bevel gears. These active bevel gears, in turn, drive the synchronous rotation of two driven bevel gears and lifting screws. The two lifting screws then raise and lower two drive plates, lifting plates, hanging plates, and grading rods. A high-precision distance sensor accurately measures the distance between the rubber sleeve and the bottom inner wall of the grading rack. When the preset grading requirement value is reached, the high-precision distance sensor sends a signal to the controller, which shuts off motor one. The poultry egg is then placed into the grading rack from the right side. The egg rolls downwards and to the left along the rack. When the maximum diameter of the egg is greater than the distance between the rubber sleeve and the bottom inner wall of the grading rack, the egg meets the requirements and is stopped by the grading rod on the right side. Conversely, if the size is unacceptable, the egg continues to roll downwards and to the left from below the grading rod to the rubber pad.
[0017] When the industrial camera detects an egg at the grading rod or rubber pad, this invention promptly activates motor two. Motor two drives the rotating shaft to rotate, positioning the clamping plate above the grading frame. Cylinder one adjusts the position of the two clamping plates to align them with the egg. Cylinder two then moves the two clamping plates downwards, placing the egg between them. Motor three is then activated, driving the rotation of the bidirectional lead screw. The bidirectional lead screw moves the transverse plate, connecting plate, and clamping plate closer together. A pressure sensor measures the clamping force, ensuring that the force is within acceptable limits, thus stably clamping the egg without excessive force that could damage it.
[0018] 3. Finally, following the above steps in reverse, the clamping plate is reset to the top of the corresponding placement platform. The egg tray is placed between the two limiting frames. According to the measurement of the industrial camera, the front and rear positions of the clamping plate can be adjusted by motor two, and the lateral position of the clamping plate can be adjusted by cylinder one, so that the clamping plate can hold the poultry eggs to the empty position of the egg tray when there are no poultry eggs. When the egg tray is full, the personnel remove and replace it, and then the poultry eggs can be graded and packaged. Attached Figure Description

[0029] Specifically, a gripper box 87 is fixedly connected to the bottom of the cylinder 2 86. The gripper box 87 is equipped with a gripper assembly for gripping poultry eggs. The gripper assembly includes a motor 3 84 fixedly connected to the front side of the gripper box 87. A bidirectional lead screw 89 is fixedly connected to the output shaft of the motor 3 84.

Cylinder 1 83 adjusts the position of the two clamping plates 811 to align them with the eggs. Cylinder 2 86 moves the two clamping plates 811 downwards, positioning the eggs between them. Motor 3 84 is then activated, driving the rotation of the bidirectional lead screw 89. The bidirectional lead screw 89 moves the transverse plate 88, connecting plate 810, and clamping plate 811 closer together. The clamping force can be measured by the pressure sensor 812. The force applied is just right to stably clamp the eggs without damaging them due to excessive force. Finally, the steps are reversed to reset the clamping plate 811 above the corresponding placement platform 4. The egg tray is placed between the two limiting frames 5. According to the measurement of the lower industrial camera 10, the front and rear positions of the clamping plate 811 can be adjusted by the motor 81, and the lateral position of the clamping plate 811 can be adjusted by the cylinder 83, so that the clamping plate 811 can clamp the eggs to the empty positions of the egg trays.
