Optimizing Throughput with Checkweighing
Checkweighing is a critical quality control process that ensures products meet specified weight requirements while maximizing production line efficiency. Optimizing throughput in checkweighing systems requires balancing speed, accuracy, and reliability to minimize downtime and maximize output.
Parallel weighing stations (2–16 heads) increase speed without sacrificing accuracy.
Example: A 16-head system can achieve 600+ units/minute in snack production.
Real-time adjustments for:
Product positioning errors (off-center loads).
Vibration interference (common in high-speed lines).
Machine learning algorithms adjust:
Conveyor speed based on product flow.
Tolerances to minimize false rejects.
High-speed rejectors (pneumatic/mechanical):
Pneumatic: Best for <300 units/min (30–50ms response).
Electromechanical: Ideal for >300 units/min (10–20ms response).
Optimizing checkweighing throughput requires:
✅ High-speed multi-head systems for parallel processing.
✅ AI-driven adjustments to minimize errors.
✅ Compliance with NTEP/MID/OIML for legal trade.
✅ Real-time SPC monitoring for continuous improvement.
