The continuous Sorting machine uses a high-speed dynamic weight reading method to detect the weight of products on the production line. It can detect products with不合格 weight in the continuous production line and perform online judgment or automatic weight sorting control based on this. The weighing scale is particularly suitable for checking missing parts and abnormal weight deviations in packaged products. The packaged products are weighed by the weighing scale， and those that are qualified are sent back to the original conveyor belt， while those that are not qualified are removed (or an alarm is triggered and the machine stops). It also has functions such as classifying and counting products according to settings， automatically providing feedback signals to adjust the feeding equipment， displaying fault alarm information in text form， and providing various graphic statistical displays. It can save manpower， increase efficiency， avoid unnecessary losses due to excessive packaging or customer complaints due to insufficient weight， and improve customer satisfaction. It is suitable for inspection equipment on automatic production lines and packaging lines. It is applicable for heavy product detection on assembly lines； it is also compatible with two-color indicator lights (red and green)， representing overweight， underweight， and moderate weight； when the weight is OK， a green light is displayed， and the product automatically passes； when the weight is HI or LO， a red light is displayed， and the product is judged as不合格 and automatically removed； the weighing instrument adopts a full Chinese interface mode， with user-friendly interface design and convenient operation； the weighing range can be set arbitrarily； the upper and lower limit weight parameters can be set arbitrarily.

The weighing sorting machine is supported by 2 Weighing modules on each of the front， middle， and rear sides installed under it. The weighing modules are connected in series and connected to the PLC programming weighing instrument. Through the PLC programming weighing instrument， the output voltage of the weighing modules when the weighing sorting machine is unloaded and the reference voltage required for the platform to load are set； when the weighing Feeding machine is running， the weighing modules provide an output voltage according to the loading amount， as the output voltage of the weighing modules is linear within its measurement range， so by comparing the output voltage values of the weighing modules when the weighing sorting machine is loaded and unloaded， the loading amount of this weighing sorting machine can be obtained. When the weighing sorting machine is running， when the output voltage of the weighing module is the same as the set reference voltage， the PC programming weighing instrument sends a stop feeding signal to the electrical control part of the weighing sorting machine， preparing for the next loading. At the same time， PLC can accumulate and calculate the daily， monthly， and annual production output.

In the entire control system， the Weighing system and PLC are the core， and the input signals are collected by the touch screen and weighing modules to realize the automatic transportation， transmission， and sorting functions of materials. It consists of three parts： the weighing system transportation unit， the material transmission unit， and the material sorting unit. The main working process of this system is： press the start button， the weighing system transportation indicator light is on， the weighing system receives the start signal from the PLC， then goes to the warehouse area to take materials and transport them to the material inlet， and the weighing system returns to zero position； when the material inlet weighing module detects the material and the PLC receives the signal from the weighing system， the frequency converter controls the conveyor to operate， and the material is transmitted to the sorting area； when the sorting area weighing module detects the signal， it sorts the materials according to material type and color， and at the same time， the PLC transmits the sorting completion signal to the weighing instrument of the weighing system， and the weighing system continues to execute the material transportation task.

The hardware components of the sorting system include the following aspects： the weighing system， PLC， touch screen， weighing module， frequency converter， electromagnetic valve group， conveyor， etc. The transmission and reception of signals between the weighing system and PLC adopt the I0 communication mode， and the end actuator of the weighing system adopts pneumatic control mode. When the material passes through the weighing module， the electromagnet coil is energized， and the pneumatic claw grabs and picks up the material. The input signals of PLC are collected through external buttons， touch screens， and weighing modules. The PLC output signal controls the frequency converter to achieve the variation of the conveyor's running speed. By energizing the coil of the electromagnetic valve in the electromagnetic valve group, it drives the double-acting cylinder to sort the materials, and controls the on-off of each status indicator light.
