PLC programmer · industrial automation

I build innovative machines and lines that pack faster and without downtime

PLC programming, robot integration and complete automation of custom machines. I develop packaging machines and robotic lines with no existing equivalent, each built around the customer's task: schematics, PLC logic, robots, machine vision. I take a project from the idea and specification to stable operation on the shift.

What I do

From PLC code to a production-ready machine

New machines for investment projects and production upgrades. I take care of the whole automation side: schematics, PLC, robot motion, vision, safety, and training the people who run the shift.

ROBOTICS

Robot cells

Delta and SCARA robots, pick-and-place with conveyor tracking, tray loading and depalletising.

PLC · HMI

PLC & HMI

Omron, Beckhoff, Siemens, Mitsubishi and other platforms. Structured code, real diagnostics and screens operators understand.

VISION

Machine vision

Cognex, Keyence and Omron, camera-to-robot calibration, inline quality checks and rejects.

FAT · SAT

On-site start-up

FAT and SAT, commissioning, operator training and documentation people actually use.

How I work

From specification to a stable shift

  1. Requirements

    I go through the spec with the mechanical designers and the process engineer: cycle time, formats, safety.

  2. Design

    Schematics in EPLAN or WSCAD, component selection and purchasing.

  3. Program

    PLC, HMI and robot motion, plus communication with the other machines on the line.

  4. FAT & start-up

    Machine test in the workshop with the customer, then installation, commissioning and SAT.

  5. Handover

    I train operators and maintenance and hand over the documentation.

Portfolio

Machines I have commissioned

New machines with no earlier equivalent: what each does, its cycle time and what it runs on.

Cosmetics

Powder packaging

Pack feeding, a camera checks the powder position and a robot places it into the pack. The pack is then closed, labelled, sealed and sent on.

1200 mscycle time
2 × Omron SCARA+ machine vision
From project to productionPLC, HMI, servo, VFDs
Bakery

Bun grouping

Buns are split into two streams by a servo and grouped by stoppers. Two Quattro robots place the groups on the flow-pack. 5 machines in the project.

300 mscycle time
5 machineseach with 2 Quattro robots

Industrial production

Frame production

Two saws cut strips, the main machine assembles the frames: two robots move the strips, glue is applied, 4 sides are assembled and stapled. Many servos run in sync.

1400 mscycle time
3 machines2 saws and an assembler, 2 Omron SCARA robots

Office supplies

Depalletising binder mechanisms

A robot takes the mechanisms out of the box layer by layer and removes the spacers between layers. The mechanisms split into two streams, flip and go to the customer's line.

Omron SCARArobot type

Confectionery

Chocolate candy packing

A conveyor brings the candies, a robot with vision fills gaps and removes rejects. A servo groups the candies on the fly, two traverses place them into blisters. Then packing.

FAQ

Answers to common questions

What does a project include?

The full cycle of a machine: electrical schematics, component selection, PLC and HMI programs, robot and machine vision integration, commissioning, staff training and documentation.

Do you take on non-standard tasks?

Yes, most of my machines are built around a customer's specific task, and no equivalent existed on the market.

Which platforms do you work with?

PLC: Omron, Beckhoff, Siemens, Mitsubishi. Robots: Omron, KUKA, FANUC. Machine vision: Cognex, Keyence, Omron.

Do you commission the machine on site?

Yes, commissioning is part of the project: FAT and SAT, tuning to the real product, operator training.

What documentation do you hand over?

Electrical schematics, PLC and HMI programs, and documentation that staff actually use.

Which languages do you work in?

Ukrainian (native), English, Polish, Russian. I write technical documentation in any of them.

Is this suitable for grant-funded projects?

Yes. I deliver the electrics, the program and FAT/SAT at the customer's site for new, non-standard machines, and some customers have received funding for such machines. The customer files the application, I take care of the technical part.
