Engineers from Rockwell Automation developed a new bill of materials, based on Allen-Bradley® components, and were able to lower the total component price while also reducing the total cost of ownership for the end user. A smarter drive application was also developed – based on two Allen-Bradley PowerFlex® 4M drives, for the conveyor and cap sorter – as was an HMI solution with a tailored symbol library, which resulted in a friendlier user interface.
“Rockwell Automation also offered us a greater range of controllers,” Carlberg continues, “so we were able to get a best-fit solution that more closely matched the machine’s needs. Not only is the Allen-Bradley Micro800™ PLC more economical, it also takes up less space and requires fewer ancillary cards. We are also able to control the pneumatic system directly from the PLC.
“Our customers can make use of the Connected Component Workbench software, too,” he continues. “When any of our clients need an update, I can simply email them a programme and they can do the rest themselves. I have had clients that can’t even start a coffee machine, but can still download and deploy a programme using this software!”
“We are looking to migrate all of our machines over to a Rockwell Automation control architecture,” Carlberg elaborates. “The bigger Allen-Bradley PanelView™ 800 HMI means we can develop more intuitive displays. By making the display larger and clearer, we have more room to deliver messaging for both alarms and remedial action, removing some of the technical knowledge needed to identify and remedy production issues. This type of visibility is an incredibly strong argument for this technology.”
Bergkvist adds to this: “The HMI indicates if anything is wrong, such as running out of caps… small things like that. The most important data it shows is the exact CO2 pressure we're on, in the machine and in the bottles. Using this information, we can control flow valves and filling levels and make other small but helpful adjustments, all based on information from the screen. All beers are different and have their own personalities. With help from the technology, we can adjust the machine based on the beer we are bottling, instead of the other way around.
“This is the first bottling machine in this young brewery, so it’s quite a big deal for us. But what I have noticed from working with another non-automated machine is that we're not seeing as much waste beer – or “staffies” in proper technical language – in this brewery.
“I just don't have the time and patience to figure out tech issues,” she concludes. “My experience with technology is very limited; although I can do some basic ‘hillbilly’ constructs and some normal around-the-house type fixes. However, the program that Pontum provided us with is quite idiot proof. I have not had any problems with learning it.”
The results mentioned above are specific to Sälens fjällbryggeri and Pontum’s use of Rockwell Automation products and services in conjunction with other products. Specific results may vary for other customers.
