The automatic rice bag palletizing robot arm efficiently handles 5–50 kg rice bags with stable, precise stacking. It reduces labor costs, minimizes bag damage, saves warehouse space, and supports continuous 24/7 operation, making it an ideal solution for rice mills, export packaging, and high-end rice brands.
— A High-Efficiency Intelligent Palletizing Solution Designed for Modern Rice Processing Plants
The fully automatic rice bag palletizing robot arm is a next-generation intelligent stacking system engineered to improve packaging-line efficiency, reduce manual labor, and accelerate the automation upgrade of rice-processing factories. Built on an advanced industrial robot platform and optimized for the characteristics of rice bags (soft material, slippery surface, deformation, heavy weight), the system integrates a rice-bag-specific gripper, adaptive palletizing algorithms, pallet-conveying modules, bag-shaping devices, and various industry-tailored enhancements.
It is capable of handling 5–50 kg bags with exceptional stability and reliability. Seamlessly interfacing with weighers, filling machines, sewing/heat-sealing equipment, metal detectors, conveyors, and traceability systems, the robot enables a truly fully automated rice packaging and palletizing line.
With a capacity of 600–900 bags/hour and 24/7 continuous operation, the robot ensures consistent stacking quality without fatigue or fluctuation. Pallets are firm, neat, and optimized for storage and container loading, significantly reducing labor intensity, bag damage, and workplace dust exposure.
It is an essential automation solution for medium and large rice mills, rice export factories, brand-grade rice plants, and rice packaging centers, and supports future upgrades toward smart warehousing and digital grain factory construction.
(Engineered Specifically for Rice Bag Handling)
1. High-Speed Palletizing for 5–50 kg Rice Bags
The robot is optimized for high-rate bag handling, achieving 600–900 bags/hour depending on layout and model. Its motion trajectory and grasp-release cycle are tuned for soft-pack rice bags with high deformation characteristics.
2. Superior Stability Without Manual Intervention
The system utilizes vibration-suppression technology, slow approach positioning, and servo-controlled smoothing to ensure stable release, preventing misalignment or bag deformation during stacking.
3. Consistent Pallet Shape and High Stacking Accuracy
With precision repeatability down to ±0.5 mm, the pallets produced are neat, uniform, and suitable for forklift transport, warehouse racking, and container export.
4. Supports Multi-Line and Multi-Specification Production
The system can automatically identify bag types and switch between 5, 10, 25, and 50 kg products without major adjustments, perfectly supporting modern diversified rice production lines.
1. Industrial-Grade Robot Body
Built with high-rigidity arms, precision reducers, and heavy-duty bearings, the robot offers exceptional durability for continuous high-load operations in rice-milling environments.
2. Anti-Dust Protection for Grain Processing Plants
Electronics, joints, motors, and drives are sealed using IP65-level protection to prevent dust intrusion and ensure stable long-term operation despite airborne flour and rice powder.
3. Optimized for Heavy Bags
Standard payloads range from 140–300 kg, enabling the robot to handle large rice bags, multiple-bag gripping, or multi-row palletizing.
4. Long Service Life and Low Maintenance
High-quality servo motors and lubricated gear systems extend equipment lifespan, reduce downtime, and greatly lower long-term operating costs.
1. Customized Rice-Bag Gripper
Using friction plates, soft-pressure clamps, vacuum assistance, or hybrid gripping structures, the gripper ensures secure handling of soft and variable rice bags.
2. Anti-Slip Design for Coated Poly Bags
Special anti-slip materials avoid tearing or damaging packaging while maintaining a stable hold even on smooth woven bags or laminated PE bags.
3. Adaptive Bag Thickness Compensation
Intelligent pressure control adjusts gripping force depending on bag fullness and deformation to prevent slippage or over-compression.
4. Integrated Bag Shaping and Flattening Module
Before stacking, the gripper can gently flatten bag surfaces and adjust edge alignment, ensuring consistent pallet shape and improved vertical stability.
1. Palletizing Robot Body
Core 4-axis or 5-axis industrial robot arm with a wide working radius and high-speed cycle performance.
2. Rice-Bag Gripper
Fully customized gripping tools for different bag types, materials, and weight classes.
3. Bag Infeed Conveyor System
Automatically transfers bags from sewing/heat sealing to the specified gripping position.
4. Pallet Dispenser / Automatic Pallet Feeding
Continuously supplies empty pallets, enabling uninterrupted palletizing without manual handling.
5. Full Pallet Output System
Conveys completed pallets to the storage or forklift pickup area.
6. Safety Protection System
Includes light curtains, protective fencing, emergency stops, and fault monitoring for operator safety.
From Filling → Gripping → Palletizing → Warehouse Outbound
Bag filling: Rice is filled and sealed by automatic weighing and packing machines.
Bag transfer: The sealed bag is conveyed to the robotic pickup area.
Position correction: Sensors ensure accurate bag positioning before gripping.
Robotic gripping: The robot picks up the rice bag with the specialized gripper.
Layer-building: Bags are arranged according to the preset stacking pattern.
Layer shaping: Each layer is compressed or aligned for better pallet form.
Pallet transfer: Completed pallets are automatically conveyed to the exit area.
Warehouse integration: Pallets can integrate with AGVs, AS/RS systems, or smart warehouse software.
