Automatic Bag Palletizing System | Bag Palletizer | LIMA

The Automatic Bag Palletizing System is an advanced end-of-line solution engineered for the efficient and automated stacking of bagged goods onto pallets. This system is crucial for streamlining packaging operations, improving output, and ensuring that finished products are ready for storage or distribution with perfect stack stability.

How it Works

Bags are conveyed to the system's high-level grouping unit. Here, they are precisely arranged according to predefined patterns specific to the product and pallet size. Once a layer is formed, the system pushes the bags onto a layering unit. Top compression and side panels shape each layer, ensuring accurate alignment and stability before it is placed onto the pallet. This process guarantees that the bags are not damaged, and each layer is balanced and firmly pressed, resulting in stable and geometrically precise pallet stacks.

Key Benefits

Implementing an automatic bag palletizing system offers significant advantages:

• Increased Production Efficiency: Automating the stacking process eliminates bottlenecks and speeds up the entire packaging line.
• Higher Transfer Capacity: The system handles high volumes of bags, matching the speed of upstream equipment.
• Improved Safety: Reduces the need for manual handling of heavy bags, minimizing workplace injuries.
• Reduced Labor Costs: Automating a labor-intensive task frees up personnel for other duties.

Applicable Industries and Materials

This versatile palletizing system is suitable for a wide range of bagged products across various industries, including:

• Cement
• Dry Mortar
• PP Plastic Resins
• Sealant Powder Materials
• Laundry Additives
• PP Granules

Customizable Palletizing Patterns

The system is highly adaptable and can be configured to accommodate various bag dimensions and desired stack heights. Common palletizing patterns are supported, such as:

• 5 bags per layer, 8 layers high
• 6 bags per layer, 7 layers high
• 8 bags per layer, 8 layers high
  Custom patterns can be programmed to optimize pallet load stability and density based on specific product and packaging requirements.

Machine Structure and Key Components

The automatic bag palletizer is built with robust components designed for reliable, high-speed operation:

• Bag Pushing Device: Works with the layering unit, top compression device, and side panels to precisely shape and align each layer of bags before placing it on the pallet.
• Bag Turning Device: Driven by a servo motor for smooth, precise bag positioning, ensuring minimal noise and risk of damage during orientation.
• Touchscreen Control System: Offers a user-friendly interface for easy configuration of different palletizing patterns. It provides full monitoring of system performance, including automatic fault display and troubleshooting suggestions, simplifying operation and maintenance.
• Empty Pallet Magazine: Stores 10-15 empty pallets, ensuring a continuous supply. Pneumatic devices accurately release pallets onto a chain conveyor, which smoothly delivers them to the palletizing position.

Optional Configurations

The automatic bag palletizing system can be integrated with other end-of-line equipment for complete automation solutions:

• Stretch Hood Machine + Pallet Inverter
• Palletless Stacking capability (depending on bag type and stability)

These options allow for further optimization of the packaging process, from stacking to final load securing.
