4 Ways Servomotors Improve Rotary Auger Filler Performance

09. Feb, 2015

Need to fill 250 cans a minute with quick parts changeover? Sounds challenging, right? On a mechanical system, timing of the container feed between the infeed screws and infeed star wheel is done manually by adjusting nuts and bolts – which is very time consuming. And if products need to change, not only is time consumed, but money is, as well: changing over funnels and container seals to adjust for a new product container size means installing new funnels and seals. Funnels have to be identical to ensure product fill weight and have a polished mirror finish so that product flows quickly, and because these stainless steel funnels and machined must be precisely machined, they can cost $1,500 each.

That’s where rotary auger fillers driven by servomotors, such as those from Spee-Dee, can make a big impact on bottom lines and efficiency. Here’s how:

  1. Servo control enables users to time the system’s container transition between feed screw and infeed star wheel on the fly, so users have the ability to make adjustments to achieve the desired increase or decrease in speed without making any mechanical changes to the system – a huge time saver.
  2. The three areas of servo control (main drive, auger, infeed screws) communicate with each other, so adjustments are made quickly and smoothly.
  3. Servo drives improve no container, no fill control since the system can be stopped and started faster resulting in fewer lost containers and less product loss.
  4. Servomotors have fewer parts and require less maintenance, which translates to decreased filler downtime and less labor.

There are alternatives to mechanical systems, and servomotor driven fillers prove their efficiency time and again. To learn more about the design and benefits of Spee-Dee’s servomotor rotary auger fillers, check out our free white paper.
