PALLETIZING

Robots

Chances are you know this answer already, so we’ll keep it short and sweet: palletizing robots use a strong and accurate arm to grab, position and place products into a tidy stack on top of a pallet. Often palletizing robots are deployed for end-of-line applications in industries such as food and beverage, retail, chemical, plastics, and pharmaceuticals.

The first challenge you’re likely facing is not unique to palletizing: finding reliable skilled labor is difficult across just about every industry. Thankfully, palletizing robots fill in the gaps nicely. Their wide-ranging and hefty payload capacities free up existing staff to focus on other tasks, while taking on heavy lifting that humans aren’t equipped to do long-term.

However, the next big challenge is unique to palletizing: properly handling a wide range of SKUs, sizes and weights so cycle time can remain healthy. This requires pallet pattern and tooling flexibility, imperative qualities for a successful project.

On top of that, there are often a lot of different products that robots have to palletize. Boxes, bags, cases, bottles, cartons, pails, kegs and more. These objects might be varying sizes and weights, in poly bags, thin cardboard boxes or shrink wrapping. Kawasaki palletizing robots set themselves apart with speed and integration of any advanced peripheral equipment such as end-of-arm tooling, sensors, vision and more. More on that in a bit.

And finally, there’s still a perception that palletizing robots are difficult to learn and use. Many facilities feel they need an engineer or a high-level programmer to handle things.

But there’s good news: each one of these challenges is easily overcome with Kawasaki Robotics.

Our industrial palletizing robots help to solve the skilled labor and seasonality issues, and they’re smart enough to make sorting decisions in milliseconds. What’s more, our open software architecture allows users to easily build interfaces without limitations. And most of our robot options are yours from the jump, we don’t charge you for add-ons.

Additional benefits of Kawasaki Palletizing robots:

  • Our CP Series has a consistent form factor regardless of payload. No need to find additional floor space!
  • Every time the CP Series decelerates, it generates energy. This energy is converted back to consumable power for the robot. This decreases power needed and reduces CO2 emissions.

So if you’re looking to solve your current palletizing problems, our advice is simple: find a partner you can trust who’s easy to work with and who won’t nickel and dime you. You might choose us, and you might go with someone else. But no matter your choice, don’t compromise or settle.

Using open architecture and state-of-the-art technology, our line of palletizing robots are perfectly suited for end-of-line tasks. They bring high speeds and payload capacities that range from 80 kg to 700 kg, boosting efficiency and throughput.

Kawasaki Robotics hardware is proven and productive, and the open architecture of our software is not often seen elsewhere in the industry. We have the software suite and partners to handle various palletizing needs, customizing pallet recipes and patterns for a single product or multiple SKUs. We can create everything from interlocked to column patterns to mixed-SKU rainbow pallets and random SKU mixed pallets.

Our full stack of integration and technology partners let you leverage our software suite to provide everything you need—from simplistic to complex palletizing solutions that use AI.

And the icing on the cake: Kawasaki has inventory available. All in all, you get industry-best lead times on delivery, followed by complete freedom to develop exactly as you want to.

10 common questions answered

How many products can a robot palletize in one hour?

Normal throughput is around 1200 bags per hour when carrying only 1 bag/box at a time (depending on robot model), but this can go up to 1800 bags per hour. This can be even higher when the robot is set to carry multiple products at once (including entire layers).

What kind of tool do I need to palletize?

The tool will depend on the product being handled. The most common are:

  • Vacuum pad for boxes
  • Fork grippers for bags
  • Vacuum pads can be bought off the shelf, while fork grippers are usually custom made.
Can a palletizing robot handle multiple products?

Yes. The robot program can be made to run almost an unlimited number of products. However, this might require a change of tooling if the products are too different.

What kind of product can the robot palletize?

Almost any kind of product. The tooling will need to accommodate for the product. Box, bags, cans, lumber, cable reels, open cartons and more.

How do I select the right robot for my application?

Any Kawasaki robot can be used for palletizing. However, the RD and CP series are faster and have some features to make palletizing simpler.

  • CP robots have a much longer reach, can load up to 6 pallets and run 1800pph
  • RD robots have a smaller footprint, can load 2 or 3 pallets and run 800pph
  • CP robots are recommended if the pallet height is higher than the standard 87 inches.
How does Kawasaki handle singularity issues in palletizing?

CP and RD robots have 4 and 5 axes respectively, so they do not run into singularity issues. For other robot models (6-axis), Kawasaki offers a free palletizing feature called PALMODE to let the robot go through singularity in straight lines.

Does Kawasaki have a palletizing programming software?

Kawasaki offers a free palletizing sample program that can be used as-is or that the user can customize for their application. It only requires the user to enter the pallet pattern and teach the pick & pallet position.

Can I put a palletizing robot on a rail?

Yes. All Kawasaki robots can be used on a rail.

How do I improve cycle time for palletizing?

The best way is to reduce the distance between the conveyor and the pallet, and use a fast-acting tool to reduce delay at pick and place.

How do I deal with full/empty pallets?

There are multiple solutions. The most common are:

  • Use 2 pallets so the robot can continue working while the system waits for an operator (forklift) to come remove the complete one. This allows the robot to run almost non-stop.
  • Use a pallet feeder conveyor that will automatically index a full pallet out and an empty pallet in
