AK Checkweigher

I designed and implemented the electrical and control system of this in-house checkweigher
While my primary role is industrial automation and panel design, I also led the R&D effort—coordinating mechanical design, software, and on-site validation to reach a reliable, production-ready machine

What I did

• Electrical architecture & panel design (power distribution, protections, wiring, labeling)

• PLC/HMI development for weighing logic, reject control, statistics and alarms

• Load cell integration (signal conditioning, noise mitigation, calibration flow)

• Motion & actuators (reject mechanism timing, encoder/photocell sync)

• Field wiring & commissioning with FAT/SAT test plans and documentation

• R&D leadership across mechanical (frame, belt, reject box, access doors) and software (data logging, reports), aligning the team toward a stable release

How the system works

• In-motion weighing with high-resolution load cell and adaptive filtering

• Product tracking via encoder + sensors to isolate each package window

• Auto-zero & calibration routines accessible from HMI

• Reject control (air-blast or pusher) with safety interlocks

• Production reporting (OK/NG counts, weight histograms, batch stats)

Results

• Stable measurement at line speed with reduced false rejects

• Clean electrical build → easy maintenance and safe access

• Practical HMI → faster changeovers and fewer operator errors

Tech stack (sample)

Fatek PLC / HMI, HBM load cell, industrial encoder & photo sensors, panel accessories to IEC 60204-1

My role in one line

Electrical & automation owner, and R&D lead guiding mechanical and software to a production target
