First introduced in Europe in 2018, Beckhoff’s XPlanar technology—which enables “flying motion” for materials handling—made its North American debut at PACK EXPO Connects. The XPlanar system (1) uses planar motor tiles as a base to levitate passive movers at speeds of four meters per second with acceleration rates up to 20 meters per sec2.

The XPlanar tiles levitate by use of traveling magnetic fields generated in the planar tiles to precisely move objects in any kind of pattern through different tracks, enabling batch-of-one applications and flexibility in product handling. The tiles can be programmed to move as needed for an application by automatically lifting, lowering, tilting, or rotating while traveling.

Because the material handling tiles of the XPlanar system float above the surface, Beckhoff said XPlanar offers maintenance-free motion control for complex packaging, inspection, and material handling applications.

Collision avoidance for the tiles is put into effect once the user programs the XPlanar using TwinCAT 3 software, said Jeff Johnson, Mechatronics Product Manager at Beckhoff. “The software includes all of the configuration tools, motion function blocks, and collision avoidance functionality. Because the movers travel on programed tracks, users can prioritize cross-over tracks,” he said.

A particularly interesting feature of the XPlanar system is its anti-sloshing functionality, based in the TwinCAT 3 software, for use in applications involving movement of liquids. According to Johnson, the XPlanar anti-sloshing ability is enabled by the six axes of coordinated motion used on each mover. “Beckhoff has developed motion algorithms that create very smooth acceleration and deceleration profiles,” he said. “Think of it as a very soft ‘S’ curve for acceleration/deceleration.”

Image #1 in the article text.Image #1 in the article text.Johnson added that XPlanar’s planar motor tiles can be coated with stainless steel, glass or any another surface to “ensure XPlanar is a sanitary, wash-down-capable solution.” He added that Beckhoff supplies the motor tiles and movers, while the machine builder is “responsible for building the machine base and the tile coverings. In some cases, coverings will be unnecessary, and in others they will be critical. This offers the machine builder and end user flexibility in the design and implementation of XPlanar to suit their specific application.”

In terms of how XPlanar coordinates or connects with other systems for placement and removal of materials on the tiles, Johnson explained that products can be loaded onto XPlanar tiles via pick-and-place robots, the eXtended Transport System (XTS) from Beckhoff, manually, or via any other system the user chooses to integrate with XPlanar. “Most robot manufacturers offer high-speed EtherCAT interfaces which enable very fast and synchronized communications between XPlanar and the robot,” he added. “This creates a faster cycle time versus using an asynchronous Ethernet protocol.”

Also featured by Beckhoff at its PACK EXPO Connects exhibit was the XTS Hygienic—a stainless steel, IP69K version of the XTS system featured at PACK EXPO 2019. This new hygienic version is designed for wash-down production environments in packaging, pharmaceuticals, and food and beverage.

Beckhoff’s XTS material handling system combines rotary and linear drive principles into a linear transport system for packaging machines. The system features customizable motor modules, mechanical guide rails, wireless movers, power electronics, EtherCAT communication, and position measurement in a compact form factor that Beckhoff says reduces the machine footprint up to 50%. The XTS movers can move as fast as four meters per second and achieve acceleration exceeding 100 meters per second2. The XTS’s flexibility allows it to be designed in circles, clothoids, S-curves or in straight segments. The tracks can operate horizontally, vertically, or at angles, and can handle parts with single or multiple movers.

In the new XTS Hygienic version showcased at PACK EXPO Connects, the system’s new Track Management functionality was also highlighted. This allows individual movers to transfer between multiple XTS systems, enabling further customization, quality inspection, and automatic defect ejection.

Explaining which components of the XTS Hygienic version are stainless steel, Johnson said, “The motor modules and rails are stainless, while the movers have stainless and aluminum options. There is also a NiTuff coating option for the aluminum machine base. Since it is rated IP69K, we went to great lengths to design it for easy cleaning by including food-safe seals and ensuring that the surface can withstand harsh chemicals in washdown environments.”Image #2 in the article text.Image #2 in the article text.

The XTS also has the ability for its carriers to be tilted—like the tiles on the XPlanar system—even though the XTS has just one axis of linear motion.

Data, analytics, and control in one device
Emerson Automation Solutions
is a company long known for the application of its technologies in the continuous processing industries. But with its acquisition of GE Intelligent Platforms in 2018, the company now supplies a much broader array of automation technologies, allowing it to extend into the discrete manufacturing industries such as packaging machinery OEMs and batch manufacturing industries including things like consumer packaged goods and food and beverage.

Derek Thomas, Vice President of Sales and Marketing for Emerson’s machine automation solutions, said, “What we’re highlighting this year at PACK EXPO Connects is our ability to deliver scalable machine architectures, whether that’s micro control systems, compact systems, large systems or high availability systems (where PLCs need to keep running while software updates are made).”

More specifically, Thomas noted Emerson’s focus on the concept of a supervisory edge controller (2). “Every packaging line has multiple PLCs,” he said. “You’ve got one for the filler, one for the labeler running at high speed, one for the case erector, etc. And on top of that, you usually have a supervisory PLC that’s synchronizing the line itself and is connected to the SCADA (supervisory control and data acquisition) system. The ability to have one platform that can span all of this—that could do the logic, the visualization, and the SCADA functionality on a single piece of hardware that made it a true supervisory controller with one set up, one configuration, and one device to maintain and upgrade—that’s what we’ve been doing with our control platform.”

This new controller development is an extension of Emerson’s PACEdge controller. Emerson is expanding this device with technologies gained via Emerson’s acquisition of Progea in October of 2020. Progea is a provider of industrial Internet of Things (IIoT), plant analytics, human machine interface (HMI) and SCADA technologies. The addition of Progea’s Movicon software capabilities to Emerson’s PACEdge software enables Emerson’s control capabilities to extend beyond devices or machines to complete line control.

This soon-to-be-released controller, designed to create a comprehensive data, analytics, and control ecosystem, will be known as PACEdge IIoT. PACK EXPO Connects attendees were able to a preview this system at the event.

Emerson now has a standard package that can be used to do 3D machine visualization or full line visualization as well as OEE calculations and energy calculations, Thomas said. “Today, if you wanted to have a controller plus IoT plus OEE, you would have to have at least two different pieces of hardware and at least three different software packages from any company; we’re the only one that can now do it all in one.”

Sending a day’s worth of data from once piece of industrial equipment to the cloud is not only impractical, it’s incredibly expensive. “Especially when you consider that one piece of equipment can generate more data in one day than Twitter does in a full year,” said Rich Carpenter, General Manager, Product Management of Machine Automation Solutions at Emerson Automation Solutions.

This reality is what’s driving the focus on data aggregation and analysis to the edge.Image #3 in the article text.Image #3 in the article text.

“When you bring all that data down to the edge, you’re making it more accessible to the operator, and that’s how you’re going to realize OEE (overall equipment effectiveness),” said Carpenter. “By putting all this capability in one box, designed for industrial applications—from the hardware to the software—that makes a big difference. Other companies do this by using an industrial PC that they virtualize and run on a soft PLC on top of Windows. However, running your production’s critical applications this way means that you’re not doing it on a system that’s designed to have the reliability of a traditional deterministic control system.”

Carpenter explained that Emerson’s approach is to use a hypervisor on the controller to run the applications, the HMI, and the edge software so that users “keep the reliability of the deterministic engine running their production line—even if an app crashes.” (Editor’s note: a hypervisor is software that runs virtual machines separate from the system’s operating system and hardware resources).

With the addition of Progea’s Movicon software, Carpenter said one of the things about it that’s so attractive is how easily smartphones, tablets, and HoloLens can integrate with it. “Users can go out into the plant and still get all the information they need via a mobile device without having to go to the nearest terminal.”

Cost-effective electric actuator and advanced I/O
Festo
showed a low cost and easy-to-use electric actuator (3) that is an alternative to pneumatic actuators that are typically less expensive and easier to maintain, but don’t provide the same level of benefits of electric automation.

At PACK EXPO Connects, Festo introduced its Simplified Motion Series (SMS) of electric drives equipped with Digital I/O and IO-Link connectivity to enable the intelligent communication associated with the Industrial Internet of Things (IIoT).  For those machines and lab instrumentation where compressed air for pneumatics is simply not feasible, SMS provides a cost effective, easy to apply, and well-featured electric option.

The actuators are built for simple motion between two mechanical end positions or for pressing and clamping tasks, just like pneumatic actuators. But according to Festo, the SMS all-in-one design including actuator and integrated motor and drive, are easy-to-install by simply mounting the axis to the machine and connecting two cables. In addition, the drives offer optimized motion characteristics including gentle cushioning while advancing and retracting into the end positions and pressing and clamping functionality. The parameters for advancing and retracting speed, as well as pressing and clamping force, are set directly on the drive. End position, cushioning path, and manual operation are also set on the drive.

Units in the initial release include toothed belt axis, spindle and toothed belt axis, mini slide, electric cylinder, and rotary drive. The drives are plug-and-play for fast startup and no additional software or specific know-how is required.
