Auger systems that use direct drive servo motors for blendingand filling food pouches are an improvement over stepper motor and traditional clutch/brake systems resulting in increased speed, repeatablefilling accuracy, and reduced system maintenance.
Operating atup to 120 fills per minute, these new servo driven systems from SpeeDee Packaging Machinery Inc., when equipped with Zero-Max CD couplings, are able to fill dry products with repeatable accuracy into one pouch or package. The rapid start/stop auguring motion is smoothed out bythe coupling so there is no undesirable resonance or vibration duringoperation. High speed filling cycles are programmed to fill to specified weights to within a gram, which eliminates expensive product “giveaway.”
“We tried other couplings in our auguring systems years ago,” reports Timm Johnson, Spee Dee vice president. “None were rigid enough, and they developed resonance problems. So we went to the Zero-Max CD couplings. They gave us the torque rigidity we needed.”
The systems operate at top speed around the clock, 24/7, with the systems accelerating from 0 to a maximum 1,400 rpms and the coupling handling top torque loads of 3785 in. lbs. “We’ve had no problems with backlash or vibration using the CD couplings,” Mr. Johnson reported. “We’vebeen using them for over four years with several hundred in the field.”
