Checkweighers for Automated Packaging Lines

1. System Integration & Functionality

Modern checkweighers serve as critical quality control stations in automated packaging lines, performing high-speed, in-motion weight verification with precision. These systems integrate seamlessly with:

• Filling machines (auger, volumetric, net weight)

• Labeling systems

• Case/tray packers

• Robotic palletizers

Key integration features include:

• PLC communication via PROFINET/Ethernet IP

• Mechanical synchronization with line encoders

• Reject coordination with downstream equipment

2. Mechanical Configuration

• Belt Systems:

  • Widths: 200-600mm (adjustable)

  • Materials: FDA-approved PU, metal-detectable options

  • Speeds: 0.2-2.5 m/s (synchronized with line)

• Frame Designs:

  • Compact models (1500mm length) for tight spaces

  • Extended tunnels (3000mm) for unstable products

  • IP65/IP69K washdown versions

3. Data Integration Capabilities

• Barcode/RFID Synchronization:

  • GS1-128 compliance

  • Serialization for track/trace

• Cloud Reporting:

  • OEE calculations

  • Weight trend analytics

  • Automated QC reports

4. Packaging-Specific Solutions

4.1 Food Packaging Applications

• Flexible Packaging:

  • Vibration damping for light pouches

  • Anti-static belts for chips/snacks

• Rigid Containers:

  • Impact-resistant weighing platforms

  • Lid detection sensors

4.2 Pharma & Medical Devices

• Blister Pack Verification:

  • 0.01g sensitivity

  • Missing pill detection

• Sterile Environments:

  • Cleanroom-compatible

  • VHP-resistant materials

5. Future Developments

• Vision-Weight Fusion: Combined inspection in one unit

• Edge AI Processing: Instant weight anomaly detection

• Self-Learning Systems: Automatic tolerance adjustment

Many products have been applied  patents. 

  Under the advanced test equipement, technical workers and rich experice, we manufactured high qualified truck cales, platform scales, bench scales, crane scales, highway axle scales, as well as spare parts like indicators and loadcells. We have exported to RUSSIA, KSA, USA, UK, HOLLAND, SPAIN, ITALY etc many different kind of countries, our good quality and timely delivery has attracted over 200 long term distrbutors all over the world.

Our yearly export collection amount keep about 5000,000 to 10000,000 USD, among of this, our project for the foreign railway, highway and government is the majority. By the way, We can supply both ODM and OEM design also.

  Our company havs been awarded ISO 9001, CE, SGS, OIML cetificate for our products, all weighing scales are 

pre-calibrated before shipping, We deicated to the spirit of " Quality come first forveve and technology detemines the productivity"since extablished, and we have benifited from it and quietly brilliant for over 15 years.

More and more wonders and brilliant future will be made be by SMARTWEIGH!
