34 BEST PRACTICES // APRIL 2013 www.PackagingDigest.com Filling with minimal labor, maximum output At Grain Millers, PACKAGING PRODUCTION GETS A 40 PERCENT BOOST by upgrading to a new automated filling system. and, finally, place it on a pallet. "It was a tedious and extremely tiring process," Selby says. "It really took expertise to properly run the manual machine, and it was extremely labor intensive work." Te physical strain left operators fatigued, often with sore arms and backs. In addition, the system required two or three operators at any given time. In a typical workday, operators would rotate out and take frequent breaks to keep fatigue at a minimum. Tat created another problem. Te constant pauses and downtime meant inefficient production and lower bag filling rates. Te Grain Millers team knew it needed to find a solution, one that would increase production efficiency by decreasing labor requirements. Te company's research led to the Topline, a machine that seemed like the ideal solution. Even so, Grain Top of the line Te fully automated system accomplishes the entire bagging process from product weighing, to filling and finally bag closure. "It's really a remarkable system," Selby says. "One of our biggest challenges had been finding operators who could run the labor-intensive system, both from the skill level required and the physical demand. When we saw Edited by Lisa McTigue Pierce, Executive Editor how easy the Topline system was to operate, we were pretty much sold." Te Topline weighs the product, fills the bags, seals the filled bags and, best of all for Grain Millers, Tere's tired and there's down for the count. requires only one operator to oversee the process and Eugene, Oregon-based grain processor Grain stack empty bags into the automatic bag placer.

Once inside, the Topline takes an and workers who no longer have to break their empty bag from a preassembled bundle, fills it to its backs to get the bagging job done, Grain Millers specified weight and then ends the process with the increased its production by about 40 percent. densification and sealing of each bag.
