The Challenge

Add an additional stretch wrapper to the system to prevent production bottlenecks that drive up labor costs.

The Arena Solution

To get a clear visualization of the operation with an additional stretch wrapper in place, PepsiAmericas turned to technology partner Rockwell Automation. The company wanted to reduce the risk of the unknown and create a “picture” of success with the new equipment. Using Rockwell Software® Arena® simulation software, a tool that helps companies model new or existing systems to better understand how they work, PepsiAmericas could create an initial design concept prior to installation. The company could then use the Arena software to calculate the many variables that can occur in the process during production. PepsiAmericas chose Arena software because of its sound reputation in the simulation market and relied on Rockwell Automation for its analysis expertise and its knowledge of the unique challenges beverage manufacturers face.

The project was divided into two phases. The first phase included a twoday simulation training course for PepsiAmericas engineers. As part of the training, the engineers learned how to create a detailed layout of the fullpallet conveyor system. After completing the course, Rockwell Automation consultants helped the engineers develop an interactive model of the system. This model allowed the team to view a simulation of the process, review controller programming code andmexamine production data under different variables.

The animation allowed the engineers to view and manipulate the system under a variety of conditions. The team was able to run the model with different scenarios using production variables such as flow rates, product volume and conveyor speeds. With each scenario, the team could evaluate system efficiency based on the output from the Arena software.

The model allowed PepsiAmericas engineers to better understand the system, from bottling line to stretch wrapper, and identify the process problems causing the backups. By replicating the scenarios numerou times over, the team was able to confidently recommend a solution to management.


Through a series of simulations, PepsiAmericas discovered that by changing a portion of the controller programming code that governed the pallet movement from the five palletizers to the two stretch wrappers, it could eliminate the backups and accommodate the additional volume. There was no need to purchase and install a third stretch wrapper, which ultimately saved the company $150,000.

Within two months of embarking on the project, the Rockwell Automation simulation solution helped the team visualize and model the full-pallet conveyor system. This enabled the team to justify its solution and communicate recommendations more effectively to management. It also helped the team better define the logical processes of the system and its controller programming code.

By working with Rockwell Automation to simulate the application, PepsiAmericas was able to evaluate upstream process conditions to improve traffic control, reduce system downtime and achieve optimum efficiency. In addition, it helped PepsiAmericas take advantage of simulation technology, which the company plans to use for future modeling projects.

The results mentioned above are specific to PepsiAmericas Inc.’s use of Rockwell Automation products in conjunction with other products. Specific results may vary for other customers.
