Stacking machines are designed to automate the process of collecting various items, including flat products, and systematically arranging them in a precise order or stack. These machines are utilized across multiple industries to enhance efficiency in packaging lines, where they prepare goods for shipping or storage by placing them onto pallets. Their application is critical in sectors where the rapid and orderly handling of products is necessary to maintain throughput and minimize manual labor. By integrating sensors and programmable logic controllers, stacking machines can adapt to handle a diverse range of product sizes and shapes, ensuring versatility in operation and alignment with specific production requirements.

These systems may operate as stand-alone units or in combination with conveyors, robotic arms, or palletizers, automatically forming layers and transferring them to the appropriate downstream process. Adjustable guides, stack height sensors, and programmable stack patterns allow for smooth operation and quick changeovers.

Typical products and applications include:

• Flat cartons or cardboard sheets: Stacked prior to palletizing for shipping
• Printed materials (e.g., labels, inserts, booklets): Organized into uniform stacks for bundling
• Trays or clamshell containers: Aligned and layered for secondary packaging
• Flexible packaging or pouches: Grouped and staged for case packing
• Foodservice items (e.g., paperboard sleeves or plates): Stacked in uniform counts for distribution

Additional Considerations:

• Improves consistency and throughput versus manual stacking
• Reduces operator fatigue and workplace injuries
• Compatible with robotic pick-and-place or palletizing systems
• Stack patterns and orientations can be customized for product type and downstream equipment
• May include automatic transfer to case packing or wrapping stations
