Senior Packaging Systems Engineer

I work on automated filling and conveying systems for chemical and industrial liquid packaging plants. Most of my projects involve drum fillers, tote lines, pallet conveyors, and all the little integration headaches that show up once equipment actually hits the production floor. I’ve spent enough time around operators and maintenance crews to know the best systems are usually the ones that are simple, durable, and easy to troubleshoot at 1am during a production run.

I keep seeing the same pattern on drum and pail lines: a $300 bracket or a two-line HMI tweak that kills a daily jam and gives back 5-8% throughput. We moved one photoeye and added 200 ms of debounce on infeed gaps. Nuisance stops vanished, operators relaxed, and we gained a pallet an hour.The entrepreneurial snag: how do you sell that value? T&M gets ignored. Packaging it as a named reliability kit with parts, install time, and a one-page payback gets traction. Nozzle health kit, accumulati...
The folks who move the needle in packaging aren’t the ones with flashy redesigns. They quietly remove the friction that bleeds a line. On drum and pail fillers that means sticky photoeyes, vague HMI alarms, misaligned rails, and air knives aimed wrong.My rule: leave every line 15 minutes better than you found it. Move a sensor out of a splash zone. Reword an alarm. Add a drip tray over a scale. Set a regulator and write the setpoint. Post torque at the capper. Update the changeover checklist wit...
Early in my career I was the first call when the palletizer mis-picked, a drum nozzle stuck, or a scale drifted. It felt good to be the fixer, but it trained the line to depend on me and hid the real problem: weak standards and no ownership at the point of use.What changed: I started hunting single points of failure and replacing them with simple, repeatable controls. Operator-safe HMI steps for zero/tare and nozzle clean cycles. Startup checks that take two minutes but prevent an hour of downti...
I keep seeing the same thing on drum and tote lines in chemical plants: fill nozzles weep, the scale deck gets gunked up, operators re-zero and clean, and we quietly lose throughput. Last month we added simple purge cups with a small vacuum pull, a timed purge in the HMI, and an interlock so the conveyor will not release until the cup cycle completes. We got back 20 to 30 minutes per shift and a lot less mess.I billed parts and a day of work. The plant got recurring uptime. That gap bugs me. The...
In solvent-heavy filling, most emissions are not from stacks, they are the little burps during fill, venting, changeover, and disconnect. In Houston's ozone season, those add up. I have seen plants miss targets from nothing more than sloppy drum vents and foamy fills.What has worked for us: vapor balance on the filler so the open bung ties to a small header and carbon bed, bottom-up fill with gentle ramp to cut splash, nozzle tips with light vacuum to catch drips, dry-breaks on hoses, and p...
My best leadership moments have happened on the floor, not in a slide deck. We cut unplanned stops by 7% on a drum line by moving the HMI into the operator’s sightline, slowing the infeed VFD during auto recover, and replacing a sticky pneumatic dump valve. That earned more trust than any capital request I have written.If you want to grow as a leader in automated filling and material handling, get great at surfacing and killing chronic losses. Keep a visible backlog of nuisance fixes. Celebrate...
I keep seeing uptime losses on drum and pail fillers traced to ten-dollar parts. Not PLC logic, not the filler head. It is the little things that slip.Examples: M12 cordset on the infeed photoeye at the scale with a loose strain relief, causing phantom indexes. Adhesive PE brackets creeping on oily UHMW. Auto drain on the FRL stuck half open, starving lance retract. Belt lacing before the scale that bumps the pallet and makes zero wander.Two fixes that paid back fast: move flow controls and add...
I used to chase every downtime fire on our drum and pail lines. It felt good to be the hero who found the bad sensor or tweaked a pneumatic valve. Throughput still sagged a month later because the little problems came back in new clothes.What helped was getting boring and systematic. We put a 15 minute daily fault review at the filler: top three stops pulled from the PLC, quick root cause on the whiteboard, one small countermeasure assigned. We cleaned up the HMI to show plain language alarms an...
