High-Precision Checkweigher for Efficient Product Weight Sorting

Monday, 12/26/2022

Discover Kenwei’s high-precision checkweigher designed for real-time weight detection and sorting. Improve production efficiency, accuracy, and cost-effectiveness for food, pharmaceutical, and industrial packaging lines.

checkweigher machine is an essential piece of equipment for modern production lines, designed to automatically sort products based on weight. Widely used in the food, pharmaceutical, aquatic products, and poultry industries, it replaces manual weighing, significantly improving production efficiency, ensuring accuracy, reducing labor requirements, and lowering costs.


How a Checkweigher Works

The industrial weight sorting system operates through a coordinated process involving the weight sensor, AD module, PLC (Programmable Logic Controller), and sorting mechanism:

  1. Weight Detection – The weight sensor converts product weight into an analog voltage signal.

  2. Signal Conversion – The AD module transforms this signal into digital weight data, representing the real-time weight of the product on the conveyor belt.

  3. Data Processing – The PLC reads and analyzes this data, calculating the product’s actual weight as it moves across the weighing belt.

  4. Sorting Decision – If the product is outside the preset weight range, the PLC triggers the reverse belt action, automatically removing non-compliant items.


Applications

Kenwei’s online weight checking machines are suitable for a wide range of packaging formats, including:

  • Bulk paper bags

  • Plastic packaging

  • Carton boxes

  • Metal film packaging

They ensure high-speed, high-precision operation in stable working conditions.
