Palletizing robots offer significant advantages over both manual labor and traditional, fixed mechanical palletizers:
Increased Throughput & Efficiency: Robots work continuously (24/7) without fatigue or breaks, consistently matching and often exceeding the speed of high-volume production lines.
Superior Safety & Ergonomics: They eliminate the physically demanding, repetitive lifting of heavy items, removing the primary cause of musculoskeletal injuries (MSIs) associated with manual palletizing.
Flexibility (SKU Changeover): Unlike conventional palletizers which require extensive mechanical adjustments, robots can switch between dozens of different product sizes (SKUs) and complex stacking patterns (recipes) almost instantaneously via a simple software command.
Load Stability & Quality: Robots place every item with high precision according to the optimal pattern, resulting in tighter, more uniform, and ultimately more stable pallet loads that minimize damage during transit.
What can a palletizer handle?
A palletizer, whether a fixed conventional machine or a flexible robotic system, is designed to handle an extremely wide variety of finished products from virtually every industry. The determining factor is the End-of-Arm Tooling (EOAT), or gripper, which is customized for the specific product.
Here is a comprehensive breakdown of what automatic palletizers can handle:
| Product Category | Examples of Items Handled | Necessary Gripper Type |
| Boxes & Cartons | Standard shipping cases, corrugated trays, display boxes, shrink-wrapped trays, retail-ready packaging. |
Vacuum Grippers (most common, use suction), Clamp Grippers (for side stability), Underneath Grippers (for weak box tops).
|
| Bags & Sacks | Bags of cement, flour, feed, sugar, coffee, pet food, or plastic pellets. |
Bag Grippers (specialized clamping jaws) that flatten the bag or use heavy-duty vacuum suction to maintain stability.
|
| Containers & Packs | Trays of bottles/cans, multipacks, crates, pails, buckets, small barrels, or tubs. |
Custom Clamp Grippers (for gripping sides), Fork Grippers (for lifting an entire layer of packs), or Boom/Mandrel (for open cores).
|
| Fragile Goods | Glass vials, cosmetic bottles, medical device kits, packaged electronics. |
Soft-Grip Grippers and Vacuum Grippers with gentle force sensors, handled with slower, precise robotic movements.
|
| Heavy & Bulky Items | Automotive parts (e.g., engine components), metal castings, tiles, bricks, large electronics. |
Gantry Robots with heavy-duty mechanical or magnetic grippers, utilizing maximum payload capacity.
|
| Irregular/Mixed Loads | Various sizes of e-commerce packages, mixed-SKU logistics pallets. |
Vision-Guided Robotic Grippers that use 3D scanners to identify the size and position of each unique item for optimal placement.
