Check weighing and sorting industry solution

High accuracy, flexibility, and powerful functionality.

Multilevel sorting is a technique that classifies products based on different weights. Traditional manual sorting is not only inefficient but also prone to human error. Therefore, automated multilevel sorting has become the mainstream trend in the market.

Industry background

Dynamic checkweighers, also known as weight sorters, are automated checkweighing devices widely used in production lines across industries such as pharmaceuticals, food, seafood, beverages, health products, cosmetics, electronics, daily chemicals, light industry, batteries, and packaging. They can detect the weight of products in real-time and handle non-conforming items accordingly.

Multilevel sorting is a technique for classifying products based on different weights. Traditional manual sorting is not only inefficient but also prone to human error. Automated multilevel sorting has thus become a mainstream trend in the market.

Multilevel sorting has a vast market in China and is widely used in the sorting of eggs, fruits, seafood, and meat and poultry. The mechanical structures vary for different products.

System principles

The automatic checkweighing sorter consists primarily of a power conveying section, weighing section, main controller (PLC), human-machine interface, and sorting rejection mechanism.

The power conveying section is composed of a motor driver, motor, transmission mechanism, and conveyor belt, primarily responsible for transporting items to be sorted.

The weighing section includes the scale platform, load cell, signal cable, and Xinje XD-E1WT-CW weighing module, primarily responsible for capturing and collecting the weight of items in motion online.

The main controller manages belt movement, interacts with the human-machine interface, processes and evaluates weight signals, and provides control signals for rejections as well as checkweighing results.

The human-machine interface handles human interaction tasks, parameter settings, and recipe storage. The sorting rejection mechanism executes the corresponding rejection actions based on instructions from the main controller.

Solution Advantages

Flexible and convenient

Utilizes Xinje XD5 series high-performance PLC with fast processing speed, flexible expansion, and support for secondary development.

Strong adaptability

Built-in rolling rejection function effectively resolves the conflict between rejection distance and weighing speed.

Large capacity storage

Capable of recording inspection data with ample storage, permanently saving the data. Reports can be exported via USB drive.

Easy debugging

Equipped with screen and serial port oscilloscope technology, the entire debugging process becomes visualized, eliminating the pain of traditional blind adjustments, making debugging easy, fast, and efficient.

High accuracy

Using the Xinje XD-E1WT-CW weighing module, it offers high accuracy and good stability. Overall detection accuracy can reach 2%-3% (depending on equipment conditions).

Powerful functionality

Built-in weighing and grading for 10 specifications, combining checkweighing and grading in one machine.

Wide applicability

Multiple material recipes can be stored and easily changed, with adjustable sorting speed.

Supports remote monitoring and cloud storage

Paired with the Xinje network module and cloud platform, it offers powerful cloud database reporting capabilities.
