■ Product Brief
The Pharmaceutical Bottle Checkweighing Solution is designed to verify the weight of tablet and capsule bottles after the counting and filling process. Integrated with a tablet counting machine, this automated checkweighing system helps pharmaceutical manufacturers and nutraceutical producers identify underfilled, overfilled, or abnormal bottles before downstream packaging operations.
By combining tablet/capsule counting technology with dynamic bottle weight inspection, the system provides an additional quality control step for pharmaceutical packaging lines. Each filled bottle is weighed against its configured target weight, allowing the system to identify bottles that fall outside the preset tolerance range.
This Bottle Checkweigher is suitable for tablet counting and bottle filling lines handling hard capsules, tablets, caplets, and other solid dosage products. It can be configured to connect with upstream tablet counting equipment and downstream capping, sealing, or labeling machines, depending on the production line layout and integration requirements.

■ Product Highlights
1. Automated Bottle Weight Verification
Automatically weighs each filled tablet or capsule bottle to verify whether the product weight meets the preset target range.
2. Integration with Tablet Counter Machine
Connects with tablet and capsule counting equipment to create a coordinated bottle filling and weight inspection process.
3. Automatic Reject System
Removes bottles outside the configured weight tolerance using a suitable reject mechanism, helping prevent nonconforming bottles from proceeding to subsequent packaging stages.
4. PLC and Touchscreen Control
Provides operator access to weighing parameters, product settings, and system monitoring through a PLC-based control system and HMI touchscreen, according to the selected configuration.
5. Continuous Inline Inspection
Supports automated bottle weight inspection during production, reducing dependence on manual weight checks and helping maintain consistent quality control.
6. Production Data and Statistics
Can be configured to display inspection results, pass/reject counts, and production statistics for process monitoring and quality management.
How Does the Integrated Checkweighing Solution Work?
1. Empty Bottle Feeding & Optional Empty Bottle Weighing
Empty bottles enter the production conveyor and are automatically conveyed and positioned for the filling process. An optional empty bottle weighing system can be installed to measure and record the tare weight of individual bottles before tablet or capsule filling, helping compensate for bottle weight variations and improve the accuracy of subsequent filled-bottle weight verification.
Bottle conveying → Positioning → Optional empty bottle weighing
2. Tablet/Capsule Counting and Filling
The tablet counter dispenses the configured quantity into each bottle.
Filled bottle transfers to inspection
3. Dynamic Bottle Checkweighing
Each bottle is weighed and compared with the configured target weight and tolerance.
Inspection result determined
4. Pass / Reject Separation
Qualified bottles continue; bottles outside the configured limits are diverted.
Downstream packaging
5. Capping, Sealing and Labeling
Passed bottles move to subsequent packaging equipment when integrated into the production line.
