Q&A: Desperately seeking 'plug-and-pack'

An interview with Andrew McDonald, global automation and control manager for Unilever, maker of food and personal care brands such as Dove®, Suave®, Vaseline®, Lipton®, Skippy® and SlimFast®. McDonald is also the chief architect of an industry-wide “state model,” a term used to describe whether a packaging machine is running, down, on standby, etc.

PW: Why should packaging machinery users care about a state model?

McDonald: They shouldn’t have to care. Do you care what’s under the hood of your car? You get in, turn the key, and drive off. It’s the same with packaging machinery. The situation we have now is that if we buy five machines for a line, they each come with different control systems, and you spend forever integrating them. We do make efforts to specify machines using company standards, but some manufacturers of machines specialize in supplying certain systems. To get them to change can cause delay and an increase in cost. At home, I recently plugged in my camcorder into a new PC, and it beeped and noted, “I see you’ve got a JVC camcorder. What do you want me to do with this today?” That’s exactly how it should be with packaging lines—plug-and-pack, instead of plug-and-play, if you will.

PW: What are your views on assessing packaging machinery price versus flexibility?
