常绿包装used PACK EXPO Connects as an opportunity to unveil its new servo-driven EH-84 gable top packaging machine, which features PLC controls and servo technology fromRockwell Automation. Designed for the dairy, juice, and liquid foods markets, the EH-84 can handle fill volumes of 40 oz on up to64盎司和2升以速度为每小时8,400箱。
According to Evergreen’s Richard Szyperski, Technical Product Manager & Equipment Sales Specialist, the firm’s EQ-70 gable top machine for quarts and 1-L cartons has taken advantage of servo technology for some time. The EH-84, he says, brings servo technology to the popular half-gallon format and represents a culmination of learnings gleaned from the development of previous machines.
“我们的客户群正在寻找从机械到伺服的这种升级，”Szyperski说。“罗克韦尔是一个明显的选择，当它来到一个控制平台时，不仅因为这是我们过去使用的东西，而且因为这是我们的客户熟悉的东西。”

双车道si linear-style常绿填料ngle-index machine with seven volumetric filling valves for each lane. Actuations executed by the servos include such things as filling and the movement of the mandrels on which the flat blanks are erected and formed into gable top cartons. Szyperski is especially pleased by the improvement in accuracy gained where filling is concerned. “Filling controlled by mechanically linked pumps is just not as accurate as servo-controlled filling,” he points out. “And by using servos on the mandrels we gain considerably in control over our positioning capabilities. Plus we can now spin the mandrels without having to cycle the machine. This brings advantages in cleaning and sanitizing.”
Among the first to install the EH-84 is Orrville, Ohio-based SmithFoods, a leading producer of milk and plant-based beverages, whose VP of Operations Todd DeRoo says the business benefits of servo control are significant. “We can adjust to virtually an infinite number of sizes very quickly, and doing it probably takes 50% less time than on comparable machines that are not servo-controlled,” says DeRoo. “And in addition, everything is more accurate. We did wonder at first how the operators would respond to the newer technology, but after running the machine for an hour or two they’re reluctant to be assigned to the old lines.”
