Cobot Palletizer: a guide to buy and integrate one

If there is one task seen as repetitive and physically demanding in factories, it’s definitely palletizing. Workers can easily get tired of moving and stacking boxes all day long.

For this reason, collaborative robots have naturally become an interesting alternative for this logistic application. As workers can easily move and reprogram them, they can manage warehouse inventories with great flexibility.

But which robotic models and effectors are best suited for this application? Here’s a comprehensive guide to opting for the automation solution adapted to your needs.

Why use cobots for your palletizing process?

Moving and storing stacks of boxes has never been the most relaxing and rewarding task. And workers know this, as they would better focus on inventory and stock management instead of filling pallets all day.

Fortunately, automation solutions have been available for the past twenty years to lighten the physical load of workers in the logistics industry, but also in the electronics and food industries. Among them, industrial robots from well-known manufacturers (Fanuc, Kuka, ABB) stack products with great productivity.

However, one of the drawbacks of these industrial robots is that they require a long time for set up, programming, and maintenance. Collaborative robots address these flaws with user experience and light-weight design while maintaining equivalent performance and redundancy.

Here’s how they can help you better automate your palletizing application:

  • Easy to set up and reprogram, you can set them up within half a day on a new shop floor
  • Highly consistent motion that speeds up and intensifies your conveying flow
  • Lightweight and compact design to fit into your existing space and infrastructure
  • They are low cost and require very little maintenance

Are these benefits appealing to you? Here’s a top of the best cobot models and palletizing tools to get you started.

Choosing and integrating your cobot palletizer: a step-by-step guide

When considering automating your palletizing application, choosing the ideal cobot and palletizing end effector is only one thing. The other thing is to consider more closely how to integrate this automation solution into your existing processes.

Here’s a checklist for planning your end-to-end automation project:

1. Agree on your automation project

Before you get started, think about the goals of your automation project. Do you primarily need to relieve your operators in stock management, allow them to save time on other tasks, or gain productivity in your order processes?

The answer to this question will determine what happens next.

2. Look for the right solution

Based on these goals, you can then define your preferences for cobot models or gripper tools.

There are many purchasing factors you can consider:

  • Robot Load and reach capabilities based on the volume and shape of your boxes and pallets.
  • The performance you expect from the robots in terms of speed, accuracy and motion redundancy.
  • Gripping tool models (vacuum pump, electric, pneumatic…) according to the surface, material and shape of the objects to be moved
  • The ease of programming, installation, transport and deployment of the robots
  • The safety features of these robots to protect your workers

Depending on the value you place on these features, you can then select the cobot and end effector best suited to your needs.

3. Set up your logistics shop floor

Once you’ve found the right palletizing solution, you can then think about integrating it into your existing cell. This often involves reconfiguring the space and features of your warehouse or stock center.

For example, you may want to give workers or robots more room to move, or install elevators, mobile racks, or pallet suppliers.

4. Rethink the work organization

Setting up a new automation solution also means redefining the work organization and the employee contribution.

What will be the new role of logistics agents in your collaborative application? Will they be in charge of planning operations and monitoring robots? Or will they focus on transporting and handling more fragile or delicate products?

5. Conduct a risk assessment

Before deployment, you should also conduct a risk assessment of your new application. Even though collaborative robots can prevent potential collisions, you need to anticipate the points of contact, whether with the robot, the gripper, boxes, or pallets.

These different interactions can involve more complex work dynamics that your employees need to be aware of.

6. Plan employee training

Finally, you need to organize the training of your employees to this new solution. Even if these collaborative robots seem easier to use than other industrial tools, you still need to know how they work. In particular, you should insist on the safety protocols and features included with the cobot.

This will also help build employee confidence.
