Automated Checkweighers for Consistent Product Quality

Automated checkweighers are precision weighing systems integrated into production lines to ensure every product meets specified weight requirements. These systems combine high-speed operation with metrological accuracy to deliver:

• 100% weight verification for quality assurance
• Real-time process control to minimize giveaway
• Automated rejection of non-compliant products
• Compliance with trade regulations (NTEP, OIML, MID)
• Data integration with factory management systems

• Dynamic weight compensation for conveyor vibration
• Product tracking with timestamped weight records
• Automatic tare adjustment for packaging variations
• Multi-head configurations for parallel processing (up to 600 items/min)
• Vision integration for combined weight+visual inspection

• In-line installation between filling and packaging machines
• Synchronized rejection with downstream processes
• Closed-loop feedback to filling equipment for automatic adjustment
• Multi-lane configurations for high-volume production

1. Startup Verification: Daily check with certified test weights, zero-point stability confirmation
2. In-Process Monitoring: Real-time SPC charts (Cp/Cpk), trend analysis for predictive adjustments
3. Preventive Maintenance: Monthly load cell verification, quarterly mechanical inspection

• AI-powered weight prediction: Forecasts and compensates for drift
• Digital twin integration: Simulates performance for optimization
• Blockchain traceability: Immutable weight records for audits
• Edge computing: Local data processing for faster response
