What is a checkweigher?

A checkweigher is an automated weighing machine used in the packaging process to ensure product weights meet specified standards. Its role is critical in quality control, as it prevents underfilled or overfilled products from reaching customers. Checkweighers ensure consistent product quality, avoid product recalls, and maintain compliance with regulatory standards. By integrating into automated packaging lines, they also help improve packing efficiency and reduce labor costs.

Types of Checkweighers

There are two types of checkweighers, each designed to meet different operational needs and manufacturing process. These models vary in terms of their functionality, accuracy, and use cases.

Dynamic / Motion

Checkweigher

These checkweighers are used for weighing products on a moving conveyor belt. They are typically found in high-speed production lines where speed and accuracy are paramount. Dynamic checkweighers are perfect for continuous production, as they provide real-time weight measurements as products pass through.

 High-Speed Weighing: Accurate weight checks in motion on a conveyor belt for continuous, fast processing. 

 Precision and Accuracy: Provides high accuracy using advanced sensors and load cells to detect weight discrepancies.

 Automatic Rejection Device: Removes non-compliant products automatically to ensure only correctly weighted items proceed.

 Real-Time Data Monitoring: Tracks weight data and performance in real time for quality control and process optimization.

System Integration: Integrates with other machinery like fillers, labelers, and packagers for a seamless checkweigher system.

 Flexible Weight Range:  Handles a wide variety of product sizes and weights.

Static Checkweigher

Static checkweighers are typically used when the product remains stationary during the weighing process. They are commonly employed for larger or heavier items that do not require rapid throughput. During operation, workers can follow prompts from the system to add or remove product in a stationary position until the target weight is reached. Once the product meets the required weight, the system automatically conveys it to the next stage in the process. This method of weighing allows for higher precision and control, making it ideal for applications that demand accurate measurements, such as bulk commodities, heavy packaging, or specialized industries.

 Manual Adjustment: Operators can add or remove product to reach the target weight.

 Low to Moderate Throughput: Suitable for slower processes where accuracy is more important than speed.

 Cost-Effective: More affordable than dynamic checkweighers for low-volume applications.

 User-Friendly Interface: Simple controls for easy operation and monitoring.
