◆ Product Overview
The Pharmaceutical Bottle Filling Line Checkweigher is an intelligent dual-stage dynamic weighing system designed for high-speed pharmaceutical packaging lines. It integrates seamlessly with bottle unscramblers, tablet counters, capsule filling machines, liquid filling equipment, capping machines, and labeling systems to provide 100% online net weight inspection of filled medicine bottles.
Unlike conventional checkweighers, this system consists of Checkweigher A and Checkweigher B, enabling highly accurate net weight calculation through automatic tare weight compensation.
Operating Principle:
- Checkweigher A dynamically measures the weight of every empty bottle and collects the bottle tare weight before filling.
- The tare weight data is transmitted to Checkweigher B in real time through the control system.
- After tablets, capsules, powders, granules, or liquids are filled, Checkweigher B measures the total bottle weight.
- The system automatically subtracts the stored tare weight from the gross weight to calculate the actual product net weight.
- Bottles outside the preset weight tolerance are automatically identified and rejected, ensuring every bottle leaving the production line meets quality standards.
This intelligent dual-checkweigher solution eliminates bottle weight variation, significantly improves weighing accuracy, reduces product giveaway.
