Bag Unpacking Depalletizer

A bag unpacking depalletizer is an integrated automated system that combines robotic or mechanical depalletization with precise bag opening and material discharging functions. Unlike standalone depalletizers that only remove bagged products from pallets, this all-in-one solution completes the entire process from pallet unloading—separating stacked bags from pallets layer by layer—to automatic bag cutting, material emptying, and even empty bag collection and compaction. It is specifically engineered to handle bagged materials of various types, including powders, granules, pellets, and flakes, making it highly versatile for diverse industrial needs.

Our bag unpacking depalletizer is equipped with cutting-edge technologies and user-centric features to ensure optimal performance, reliability, and ease of use:

Equipped with advanced 3D vision systems and AI-powered pattern recognition, the system can automatically detect the exact position, geometry, and orientation of each bag on the pallet—even if bags are misaligned, deformed, or stacked irregularly. The robotic arm or mechanical gripper, fitted with customized end-effectors (such as articulated claws for porous bags or vacuum suction cups), ensures stable and damage-free gripping, with the ability to handle different bag types (pillow-type, gusseted, valve bags, etc.) without tool changes. It can achieve depalletization speeds of up to 14 bags per minute, far exceeding manual efficiency and ensuring consistent throughput.

The integrated automatic bag opening station features adaptive cutting tools that deliver precise, clean cuts to avoid material leakage and minimize dust emissions—a critical advantage for food, pharmaceutical, and chemical industries. The unique bag flipping system ensures nearly complete material emptying, reducing product loss to a negligible level (achieving an emptying rate of up to 99.99%) and maximizing resource utilization. A built-in dust removal system further maintains a clean working environment and protects operator health from harmful dust exposure.

Controlled by a PLC system and an intuitive HMI interface, the entire process—from pallet feeding, depalletization, bag opening, and material discharging to empty pallet stacking and empty bag compaction—is fully automated, requiring minimal human intervention. Operators only need to set parameters, load pallets, and monitor operations, freeing up manpower for higher-value tasks such as quality control and equipment maintenance. The system supports 24/7 continuous operation, significantly increasing production efficiency and reducing downtime associated with manual fatigue or shifts.

Our bag unpacking depalletizer is highly adaptable to different bag sizes (ranging from 220x300mm to 500x660mm) and material types, including flour, sugar, cement, chemicals, plastics, and animal feedstuff. It can be seamlessly integrated with existing production lines, such as conveyors, mixers, silos, and packaging systems, as well as AGV (Automated Guided Vehicle) systems for seamless material flow in warehouses and factories. The modular design allows for easy expansion, enabling the system to support multiple production lines or handle increased throughput as your business grows.

Safety is a top priority in our design. The system is equipped with comprehensive safety features, including protective fences, light curtains, emergency stop buttons, and safety interlocks, to prevent operator accidents during operation. For hazardous environments (such as chemical plants with explosive dust), the system can be customized with explosion-proof designs and corrosion-resistant materials, complying with ATEX zone 22 and other industry safety standards. By replacing manual handling of heavy bags (often 25kg or more), it also reduces the risk of musculoskeletal disorders (MSDs) and occupational diseases, lowering occupational morbidity rates by up to 80%.

Thanks to its versatility and reliability, our bag unpacking depalletizer is widely used in various industries, including:
