See It in Action: How an On-Site Demo Led to Same-Day Robotic Palletizer Installation

With labor shortages growing more serious, food factories are under pressure to embrace DX (digital transformation) and end-of-line automation. Palletizing—stacking heavy cartons and cases onto pallets—puts significant physical strain on workers, making it a top candidate for a robotic palletizer or cobot palletizer.

But when manufacturers start exploring palletizing automation, doubts often hold them back: "Will it actually fit in our space?" "We can't shut down the line for days." "What if it doesn't work and we waste the investment?" Many end up putting automation on hold.

This article shares the success story of MK Cheese Co., Ltd., a Morinaga Milk Group company, who cleared these hurdles with an on-site demo using real equipment—and achieved same-day startup with just one day of quick installation. Discover how Closer Robotics' hands-on support and compact cobot palletizers with a small footprint make easy-setup, small-start automation a reality.

What's Holding Back Robotic Palletizer Adoption: Factory-Floor Fears and the "No On-Site Demo" Problem

Real Challenges Facing DX in Food Manufacturing

In food factories—especially small and mid-sized production lines—existing equipment and pathways are tightly packed, leaving little room for new machinery.

Even when manufacturers want to automate, they hit a physical barrier: "There's no space for a large palletizing robot or safety fencing." A compact, small-footprint solution isn't just nice to have—it's essential.

On top of that, with daily production targets to meet, shutting down the line for days to bring in heavy equipment or reconfigure the layout simply isn't an option. Minimizing downtime and achieving quick installation is a make-or-break factor for DX in food manufacturing.

Why Don't Most Robot Manufacturers Offer On-Site Demos?

The most effective way to ease these concerns is obvious: bring the robot to your factory and test it before committing. But here's the problem—most manufacturers won't do that.

The project lead at MK Cheese, who has around 10 years of experience working with robots, put it this way: "No company had ever come to our site to do a demo."

With traditional industrial robots and large-scale palletizing systems, transporting and setting up equipment is a major undertaking. On-site demos are rarely practical. In most cases, customers have to visit the manufacturer's showroom, or make decisions based only on drawings and simulation videos. That leaves a lingering doubt—"Will this actually work in our facility?"—even as they commit to a significant investment.

How Closer's On-Site Demos and Hands-On Support Eliminate Uncertainty

Closer Robotics, an AI robotics company spun out of the University of Tsukuba, is breaking this industry norm with a commitment to real-world, on-site validation.

On-Site Demos with Real Equipment: The Deciding Factor

Closer's compact cobot palletizer, Palletizy, fits in the space of a single worker and features a mobile, caster-based design. This portability is a game-changer: Closer's team brings the actual robot to prospective customers' factories and runs live tests right next to the production line.

For MK Cheese, Closer's team visited the facility during the evaluation phase and conducted hands-on testing with the real machine. The project lead cited this as the deciding factor: "They actually came to our site and tested the robot on our floor."

By delivering the on-site proof-of-concept that other manufacturers couldn't offer, Closer made it easy to visualize the footprint and see exactly how the palletizer would run. The result: complete confidence before signing off on the investment.

Installation in Just One Day: How MK Cheese Achieved Same-Day Palletizer Startup

With concerns addressed through the on-site demo, MK Cheese moved forward with the decision to automate. Here's a closer look at the installation process and the results that followed.

The Challenge: Heavy Lifting at a Cheese Factory with a Predominantly Female Workforce

MK Cheese, a Morinaga Milk Group company known for high-quality cheese production, employs a large number of female workers. However, the end-of-line palletizing process required stacking cases weighing up to 10 kg—more than 700 per day—onto pallets. Reducing this physical burden was a critical priority.

Quickest Deployment: Full Startup in a Single Day

The solution: two Palletizy compact cobot palletizers. Because the on-site demo had already confirmed placement and operation, the entire installation took just one day—with production starting the same day.

The project lead praised the speed: "It was great that setup was completed so quickly." Palletizy's proprietary software automatically generates stacking patterns from product dimensions, allowing floor staff with no robotics expertise to operate the system intuitively. This meant a smooth transition to automation with minimal downtime.

Results and Real Feedback from the Factory Floor

Today, MK Cheese has automated the stacking of cases weighing up to 10 kg—over 700 per day—successfully reducing physical strain on workers and achieving labor savings.

A Robot Design the Team Actually Likes

Beyond the practical benefits of eliminating heavy lifting, floor staff have shared unexpectedly positive feedback:

• "The robot design is cute—I like it."
• "The name 'Closer' sounds cool."
• "I like that the logo is on the arm. It feels familiar."

As a cobot working side by side with people, Palletizy isn't seen as just another machine—it's welcomed as a new teammate that makes the job easier.

Continuous Improvement: Closer Evolves with Real-World Feedback

That said, real-world operation has also revealed areas for improvement. The project lead shared candid feedback: "Occasionally it stops due to overload," and "Cycle time might be tight—it would help if the arm took a safer, closer path to the base."

Closer takes this kind of input seriously, using it to drive system updates and refinements. The project lead also noted: "It's reassuring to see them developing new features like multi-line support and depalletizing. I'm excited about what's next."

This commitment to evolving alongside the customer—not just delivering and walking away—is what sets Closer apart.

Summary:
Start Small, Eliminate Doubt, and Automate with Confidence

"We want to bring in robots, but we're afraid of failure." "Will it really work on our floor?"

These concerns are completely natural when pursuing DX in food manufacturing. That's exactly why it's important to start small—focusing on a process where results are predictable—rather than committing millions upfront to a large-scale system.

As the MK Cheese case study shows, Closer's Palletizy is the ideal solution for small-start palletizing automation:

1. On-site demos with real equipment — See it work on your floor before you commit
2. Compact, small-footprint design — Fits into existing lines without major changes
3. Same-day startup and intuitive operation — Full installation in as little as one day

If other manufacturers have turned you down because your facility is too tight—or if you simply want someone to evaluate your floor before making a decision—reach out to Closer. Seeing the cobot palletizer in action will make the path to factory automation clear.
