1 The overall design of the sorting system. <br>The PLC-based spherical salted duck egg automatic sorting system can sort two <br>different sizes of duck eggs. The system mainly includes: ①power supply, which provides electrical energy for the sorting system; ②mechanical devices, responsible for object feeding , Transmission, sorting, storage, etc.; ③ electrical equipment, responsible for motor speed regulation, object size judgment, motor forward and reverse control, etc.; ④ software, responsible for PLC program compilation, HMI implementation, etc. In the picture, two pairs of through-beam photoelectric sensors are used. In actual applications, the position can be adjusted, the number can be increased or replaced with light curtain sensors; the actuator of the sorting motor adopts elastic blades to sort fruits, and its execution structure can be modified in actual applications. For example, the motor drives the movable guide rail to rotate horizontally to guide the duck eggs to flow into the corresponding storage box. <br>The working process of the sorting system is as follows: <br>1) Turn on the power supply, and adjust the speed of the feeding motor and conveyor motor according to the nature of the sorted fruit and the sorting capacity of the machine; <br>2) Load the material to be sorted in the feeding bucket For spherical fruits, the fruits slide into the feeding platform; the feeding motor drives the rectangular blades to push the duck eggs into the conveyor belt; the fruits are driven by the conveyor belt, sequentially pass the photoelectric sensor, the sorting slide, and finally enter the corresponding storage box; <br>3) When only the low-position through-beam photoelectric sensor is triggered, it is judged as a small duck egg, and the sorting motor rotates clockwise; when both high and low-position through-beam sensors are triggered, it is judged as a big duck egg, and the sorting motor rotates counterclockwise. When the diffuse reflection photoelectric sensor is triggered, the corresponding digital tube count is increased by 1, the sorting motor stops, and it waits for the next sorting command.

1 overall design scheme of sorting system The automatic sorting system of spherical salted duck eggs based on PLC can sort two sizes. The system mainly includes: ① power supply, which provides electric energy for sorting system; ② Mechanical device, which is responsible for loading, conveying, sorting and storing objects; ③ Electrical device, which is responsible for motor speed regulation, object size judgment, positive and negative rotation control of motor, etc. ④ Software, responsible for PLC program compilation, HMI implementation, etc. In the figure, two pairs of opposite photoelectric sensors are used, which can be adjusted in position, increased in number or replaced with light curtain sensors in practical application. The executive mechanism of the sorting motor uses elastic blades to sort fruits, and its executive structure can be modified in practical application, such as the motor driving the movable guide rail to rotate horizontally and guiding duck eggs to flow into the corresponding storage boxes. The sorting system workflow is as follows: 1) Turn on the power supply, and adjust the speed of the feeding motor and the conveyor belt motor according to the nature of the sorted fruits and the sorting ability of the machine; 2) loading spherical fruits to be sorted into a loading bucket, and sliding the fruits onto a loading platform; The feeding motor drives the rectangular blades to put the duck eggs into the conveyor belt; Driven by the conveyor belt, the fruit passes through the photoelectric sensor, the sorting slide table in turn, and finally enters the corresponding storage box; 3) When only the low-position opposite photoelectric sensor is triggered, it is judged as a small duck egg, and the sorting motor rotates clockwise; When the high and low opposite sensors are triggered, it is judged as a big duck egg, and the sorting motor rotates counterclockwise. When the diffuse reflection photoelectric sensor is triggered, the corresponding digital tube count is increased by 1, and the sorting motor stops and waits for the next sorting command.
