Checkweighers for Automated Packaging Lines

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
