Streamlined controls platform for robotic case packer

Proprietary robotic controllers are out and a familiar look and feel are in now that one controls platform is used across the entire robot case packer.

“With this new control technology, our own people and the people in our customers’ plants are able to interact with the robot using an interface with which they are already familiar.”

That’s how Michael Senske, president of Pearson Packaging Systems, describes that firm’s RTL-MX (Robotic Top Loader-Multi Access) product line. The system is used to case pack a wide variety of products, depending on the end-of-arm tooling Pearson designs for it.

Historically, whenever Pearson integrated a robot purchased from an outside source, the robot would have its own proprietary controller. “It was frequently the size of a small rerigerator,” says Senske. “It was programmed using a teach pendant, and its control system was different than the portion of the RTL-MX that we design and build here at Pearson. The part we build would typically be controlled by a Rockwell platform. The situation this created is you had one portion of the overall robotic case packing system that had to be programmed and maintained separately from the rest of the total system. To get around this, we used to install a Rockwell PLC and HMI that converted the proprietary language in the robot’s controller into something with a more familiar look and feel.”
