Palletizing Robots

Boost Output, Cut Costs With Robotic (De)Palletization

Between manufacturing and distribution comes palletizing. Many factories still do this manually, risking injuries and compensation claims. Others have installed cumbersome palletizing machines, only to struggle with unwieldy conveyors and the lack of flexibility. The alternative is a palletizing robot.

Robotic Palletizing

Manufacturing companies, from fields as diverse as chemicals, food and health care, are recognizing the advantages this technology brings. Cases, drums, bags or trays can all be palletized quickly, accurately and repeatably, and interleaving layers included as necessary. Robotic palletizing equipment with payloads of up to 2,866 pounds can stack in whatever format is needed. Uniform ventilation gaps can be guaranteed while controlled acceleration and deceleration mean there's no damage from dropping or banging cases together./p>

A robotic palletizing system offers far greater flexibility than a centralized palletizing machine. With the latest safety technology cells take up little floor space and can go at the end of a production line. This turns a group of machines into a mini-factory and eliminates long conveyors snaking their way through to the centralized system.

When different case sizes are introduced, or bag formats changed it takes just a change of program to reconfigure the robot. Operations managers like the reduction in downtime, and the marketing department loves the ability to switch formats and add SKUs at minimal cost. Modern gripper designs mean other pack formats like large bags or trays of beverage cans are handled just as easily as rigid cartons. Some advanced systems can even handle mixed pallets, making them almost as flexible as the workers they replace.

Benefits of Robotic Palletizing Systems

Productivity surges with palletizing automation, and the indirect savings can be dramatic, too. Injuries and injury-related absences are eliminated because employees are no longer lifting, twisting and bending. That means lower injury costs — and with OSHA estimating the direct cost of a hernia at nearly $50,000, those can stack up quickly. Unscheduled stoppages are eliminated as well, improving equipment utilization and increasing output from the line.

Machine Vision Technology Makes Robotic De-Palletizing More Affordable

Robotic de-palletizing is possible, too, without the need for expensive pallet location systems, thanks to the addition of machine vision technology. Cameras, using either laser scanners or stereo vision, locate the pallet in 3-D space and determine the orientation of each case, bag or tray.

Software calculates how best to unload each layer and guides the gripper to pick each unit. Depending on the product being handled, it can go straight onto the line, eliminating stoppages that occur when machines are waiting for material.

Robots are hard to maintain.
It is harder to find qualified, hard-working labor. Unlike workers, robots don’t have to be managed or trained. Robots don’t take breaks, lunch or vacations and they show up every day – they will even run 24-7. They are in position and perform their processed tasks 100% of the time.
