A project has been given to me at work, with no schematics or idea of where it was going. I need to fill 5 30ml bottles at a time with a food-grade liquid.
Based on the parts I have, I think the design was going to use a air agitated pressure pot tank which is used for spraying paint, which would work if we weren't using food grade liquid, so right off the bat I cant use that.
The main parts that I can use are an Allen Bradley micrologix plc, 2 pneumatic cylinders, a couple solenoids, start and stop buttons.
My question is: to fill a 30ml bottle with this liquid, would a positive displacement pump with a vfd be the best way of slowing the pdp down enough to fill the 5 30ml bottle at a time?
I do have a little experience with this particular plc so the ladder logic is not the issue, its the figuring out the specs for the pump and the motor. Any input would be very helpful also any links would be great. At this point im trying to determine if this is a huge waste of time and money or should I just go buy a filling machine for $3-5000.
