How a South African Food Can Manufacturer Improved Efficiency with a Cost-Effective Automatic Palletizing Solution

A Practical Automation Project for a South African Food Can Factory

As labor costs continue to rise and manufacturers look for more efficient production methods, automation has become an important investment for food can producers worldwide.

Recently, a food can manufacturer in South Africa partnered with Hubei Baoli Technology to upgrade its production line with a complete automation solution. The project included a customized can conveyor system, low-level magnetic palletizer, robotic arm, automatic strapping machine, stretch wrapping machine, can uprighting machine, lid feeding system, can oven, can turning machine, and a fully integrated conveying network connecting all major production equipment.

Unlike high-speed beverage can factories, this customer required a moderate production speed and focused heavily on investment efficiency. Instead of recommending a fully automated high-speed palletizing line, our engineering team designed a more economical solution that could fully satisfy production requirements while significantly reducing initial equipment costs.

Designing the Right Palletizing System Instead of the Most Expensive One

Every can factory has different production targets. Selecting equipment that matches actual production demand is often more important than purchasing the highest level of automation available.

After evaluating the customer's production capacity and factory layout, we recommended a customized low-level palletizer rather than a fully automatic robotic palletizing system.

This approach offered several advantages:

• Lower investment cost
• Reliable operation
• Easier maintenance
• Reduced energy consumption
• Future upgrade capability

The low-level magnetic palletizer automatically lifts and stacks empty tinplate cans layer by layer onto pallets. Compared with manual palletizing, the system dramatically improves stacking consistency while reducing labor intensity.

For manufacturers seeking similar solutions, our low-level palletizer can be integrated with various types of empty can palletizer systems depending on production requirements.

Patented Can Uprighting Machine Simplifies Material Handling

One unique feature of this project was the integration of our patented can uprighting machine.

Before entering the palletizing area, cans are automatically oriented and organized by the uprighting system. This ensures smooth downstream handling and improves overall production stability.

After the cans are arranged, operators manually place tier sheets between layers according to the customer's preferred workflow. This semi-automatic configuration provides an excellent balance between productivity and investment cost.

For factories planning future automation upgrades, the same can uprighting machine can easily be incorporated into a fully automated can production line.

Integrated Can Conveyor System Connects Every Process

One of the most critical aspects of this project was the design of the can conveyor system.

The conveyor network connects every major production stage, including the oven, turning machine, uprighting machine, palletizer, strapping machine, and wrapping machine. This creates a continuous material flow throughout the factory while minimizing manual handling and product damage.

A well-designed can conveyor system is essential for maintaining production efficiency and preventing bottlenecks in modern can manufacturing facilities. According to the Can Manufacturers Institute (CMI), automation and integrated material handling systems continue to play a key role in improving productivity and workplace safety across the global metal packaging industry.

By integrating all equipment into one coordinated system, the customer achieved smoother production flow and reduced downtime.

Flexible Automation for Current and Future Needs

One of the customer's primary objectives was to control investment costs without sacrificing operational efficiency.

For this reason, the project was configured as a semi-automatic palletizing solution:

• Automatic can palletizing
• Manual placement of tier sheets
• Manual placement of top frames
• Automatic pallet transfer

This design significantly reduced equipment costs while still delivering excellent production performance.

However, the system was engineered with future expansion in mind. As production demand increases, the customer can upgrade to a fully automatic palletizing system featuring automatic tier sheet insertion, automatic top frame placement, and unmanned pallet handling.

This scalable approach protects the customer's investment and provides a clear path toward full factory automation.

Automatic Strapping and Wrapping Improve Shipping Safety

After palletizing, finished pallets move automatically to the packaging section.

The automatic strapping machine secures the pallet load, ensuring stability during storage and transportation. Next, the stretch wrapping machine applies protective film around the entire pallet to protect products from dust, moisture, and movement during shipping.

Together, these systems help improve packaging quality while reducing manual labor requirements.

Many manufacturers implementing can production line automation consider automatic palletizing, strapping, and wrapping as essential components of an efficient end-of-line packaging solution.

Results Achieved by the South African Customer

Following installation, the customer experienced several immediate benefits:

• Reduced labor requirements
• Improved pallet quality and consistency
• Increased production efficiency
• Better product protection during transportation
• Reduced operational costs
• Enhanced production line stability

Most importantly, the customer received a solution specifically tailored to actual production requirements rather than paying for unnecessary automation capacity.
