Automatic Bag Filling & Sealing Solutions

Open-mouth bagger for automatic packaging of free-flowing bulk granular (powdery) materials

The automatic bagging machine is designed for the automatic packaging of free-flowing bulk granular (powdery) materials into open-mouth bags, including flat bags and gusseted bags. This bagging system automates key processes, including bag feeding, opening, placement, filling, sealing, and conveying. It uses robotic arms for bag placement, bag clamping, and material filling, ensuring high-speed, precise, and efficient packaging operations.

Widely used in industries such as petrochemical, chemical, fertilizer, seeds, animal feed, sugar, and construction materials, this open-mouth bagger is the perfect solution for packaging bulk granular (powdery) materials efficiently and accurately.

Packaging speed: 800-1500 bag/hour (20-50kg bag)
Air consumption: approx. 80m³/hour
Empty bag storage capacity: 150-200 bags (depending on bag thickness)
Number of bag stacks: 2 stacks (standard), 3 stacks (optional)

Applications

Automatic open-mouth bagging machine for PP granules

Automatic open-mouth bagging machine for phosphate fertilizers (3 stacks bag feeder)

Automatic open-mouth bagging machine for soda ash (2 stacks bag feeder)

Automatic open-mouth bagging machine for animal feed

Customization Options

Choose from various discharge bag clamping methods based on material flow characteristics (such as pre-feed or elevating bag clamp systems)
Customize the bag feeding platform and robotic arm bag clamping structure based on the bag specifications and opening type
304 or 316L stainless steel construction for all components in contact with materials (selected based on bulk material characteristics)

Machine Structure and Key Components

The automated bagging system consists of several integrated components: automatic bag feeder, bag feeding platform, robotic arm bag placement, bag clamping mechanism, discharge funnel, bag handling trolley, guiding system, vacuum system, and control system.

We use high-quality electrical components from leading global brands: SMC cylinders and solenoid valves from Japan, SIMENS PLC controllers, UNIPULSE weighing controllers, and SEW or equivalent servo motors, ensuring reliable performance and long-lasting durability.

The automatic bag feeder (empty bag magazine) supplies empty packaging bags to the automatic bagging machine. Operators place the empty bags in the bag magazine, and the bagging machine automatically completes the rest of the process. Once one stack of bags is used up, the next stack automatically moves into position for bag retrieval.

The automatic bag placer picks up open-mouth bags from the bag feeding platform automatically and lifts them into position for clamping, ensuring precise handling and efficient bag placement.

The bag clamp device secures the open packaging bag at the discharge point. Once the system’s automatic bag positioning detection confirms the bag is correctly positioned, the weighing scale discharge gate opens, and the bag clamp jaws also open to allow for material filling.

This bag clamp system integrates a bag set detection system with vacuum double-checking functionality, ensuring the bag set is intact and preventing material leakage. Traditional machines relying solely on vacuum recognition are limited and prone to incorrect detections, leading to material spillage. This can result in environmental contamination, lower product quality, and economic losses for the user.

Once the bag is filled, it is lowered, and the bag handling trolley clamps the filled bag, delivering it to the sealing system. This ensures the bag opening is aligned, ensuring a smooth seal. The horizontal bag retrieval and precise bag opening alignment method allows for high tolerance in bag manufacturing dimensions, reducing costs and offering better cost efficiency for the user.

The parameters of automatic bagging machine can be easily set and monitored through a touchscreen interface, offering real-time control. The electromagnetic valves, pneumatic components, touchscreen, and weighing instruments are all sealed, ensuring the system is ideal for dusty environments and providing a long-lasting operational life.

Optional Configurations

Depending on the customer's needs, additional equipment such as heat-sealing machines, sewing machines, bag flipping machines, metal detectors, checkweighers, and reject conveyors can be added to further enhance the system’s capabilities.

Heat Sealing Machine

Bag Sewing Machine

Checkweigher

Metal Detector

Reject Conveyor

Reject conveyor pushes away bags that fail check weighing or metal detection, keeping only compliant bags on the production line.

Bag handling conveyor

The bag handling conveyor uses rollers and guide push plates to push vertically filled bags that have been sealed into a horizontal position, with the bag direction consistent with the conveying direction, ensuring correct operation in the next stage.
