Bag Weighing & Filling Machine | In-Bag Weighing

The Bagging Weigher is a modular packaging line system designed for the flour, feed, grain, and pulses industries to fill powder or granular products into open-mouth bags weighing between 20 and 50 kg. As standard, it incorporates pneumatic bag gripping, integrated control automation, belt conveying, and sewing units.

Working Principle and Model Structure: In all models, when the operator places the bag onto the filling spout, pneumatic pistons automatically grip the bag securely, while the integrated automation panel manages the filling process. Depending on capacity, the system operates with two different model configurations and end-of-line solutions:

• Mechanical Weighing System (In-Bag Weighing): Weighing is performed using a mechanical counterweight system, while the bag is gripped by pneumatic pistons and the system operates with basic automation control.

• Load Cell Weighing System (In-Bag Weighing): While the bag is held by pneumatic arms, digital and precise weighing is performed using load cells; the PLC-controlled gate completes the filling at a low speed.

End-of-Line Integration: After filling, the bags released by the pneumatic arms drop onto a conveyor belt manufactured to the required length and move toward the sewing station. On the station conveyor, the bag mouth is closed using suspended manual, column-mounted automatic, or specialized sewing machines, depending on the plant’s automation preferences, completing the packaging process reliably.
