What is a checkweigher？
The Samegram checkweigher is a device that can continuously detect weight on the production line, mainly used for real-time weighing and automatic rejection of products that do not meet weight standards. It does not require stopping the conveyor belt; products are weighed instantly as they pass through the weighing platform. It can automatically sort missing or incomplete products or classify them by weight.
Solve the Most Common Production Challenges
- Product scrap due to inaccurate filling
- Compliance risks due to insufficient product weight
- Waste due to excessive product weight
- Production downtime due to unstable weighing
Dynamic Checkweigher Working Principle
A dynamic checkweigher typically consists of three continuous conveyor sections:
Infeed belt
Products enter the feeding section from the upstream conveyor line. Photoelectric sensors detect the product position and control the spacing between products, ensuring they enter the weighing section one after another evenly.
Weighing belt
As products pass through the weighing platform at a constant speed, sensors continuously collect weight signals in real time. The system uses digital filtering and dynamic compensation algorithms to deduct the conveyor belt's own weight, vibration interference, and dynamic forces during product acceleration/deceleration, obtaining an accurate net product weight.
Outfeed belt
The system determines the product's destination based on the weighing results: qualified products continue forward, while unqualified products are discarded. Simultaneously, data (weight, qualified/unqualified, time, batch, etc.) is recorded and can be uploaded to an MES/ERP system via network connectivity.
Technical Advantages of Our Automatic Checkweigher
Our weighing solutions
SameGram dynamic checkweighers provide real-time weight detection while the production line is running at full speed. After accurate weighing, products are smoothly sorted by the sorting device into underweight, overweight, and optimal weight categories without interrupting your production process.
Human-computer interaction Control system:
- Online weighing control system V1.0.5
- Color touchscreen display, 100 preset functions for products;
- Weighing information is traceable and supports one-click export to USB flash drive.
Intelligent Weighing:
Insufficient display yellow indicator light; Qualified display green indicator light; Excessive display red indicator light.
Hygienic Design
Made of 304 stainless steel, with a closed or cleanroom design, offering a high level of protection, easy cleaning, and compliance with hygienic design standards. Ideal for food and pharmaceutical production environments.
High-Speed Checkweighing
Utilizing technologies such as Electromagnetic Force Compensation (EMFR), it maintains extremely high accuracy even at speeds of 120 pieces/minute. Different models support products ranging from a few grams to tens of kilograms, with an error range of +0.1g to a few grams.
Data Linkage
Supports stricter traceability and error prevention requirements, providing Ethernet, USB, and other interfaces, enabling connection with MES/ERP, packaging machines, metal detectors/X-ray machines, etc., to upload weight data and alarm information in real time.
Integrable modules
Integrable Automatic label printing and application; Metal foreign object detection; X‑ray foreign object detection. Suitable for the food, pharmaceutical, agricultural, and logistics industries, with broad product compatibility.
