Automation

This page is a chronological timeline of the education and related experience that John Louis Kotos has acquired as an Industrial Electrician and Automation/Robotics Maintenance Technician.  My first experience was in 1979 when I was hired by Sciaky Bros. Inc. of Chicago, IL as a Class A Electrical Specialist.  Sciaky Bros. Inc. is a leading manufacturer of high-tech robotic welders including electron beam and laser welders.  Upon being laid-off in 1985, my status was Journeyman level with the International Association of Machinists and Aerospace Workers (IAMAW).

During this lay-off period, I attended a Robotics/Automated Equipment Maintenabce Technican course that was presented by the Employment Skills Institute at Moraine Valley Community College.  This was an intensive seven month course with a forty contact hour week.  Subject matter included advanced algebra, geomerty, trigonometry, AC/DC electricity, Semiconductor devices and circuits, digital electronics, microprocessors and microcontrollers, programmable logic controllers (PLCs), servo and servo-mechanisms, robotics, hydraulics and pneumatics.  I received my certificate on June 19, 1987.

I was hired by Chicago Cylinder Corporation in August of 1987. Chicago Cylinder Corporation is a machine tool shop that manufactured hydraulic and pneumatic actuators. In addition to my primary duties of electrical/electronic installations, machine maintenance, and electronic repair, a priority activity was to retrofit designated machinery.  Retrofitting included the addition of and/or the replacement of various mechanical assemblies with pneumatic actuators.  The installation of magnetic sensors, optical sensors, and solenoid operated valves were also required.  The solenoid operated valves and all remaining electrically apparatus were comnected to a Programmable Logic Controller(PLC).  The PLCs used at that time were the Texas Instrument 5TI and the G.E. Fanuc Series One thru Three.  I left Chicago Cylinder Corporation to work for Lion/Cirlce Corporation in 1990.

During my employment at Lion/Cirle Corporation, I was responisble for the electral maintenance of a paper converting operation.  This included die-cutting machinery, printing presses, silk screen machines, and ultaviolet coating machines.  It was at about the time I started that Lion Corporation bought Midwest Laminating.  Midwest Laminating incorporated the use of guilotine cutters, laminating machines, paper rewinders,sheeters, etc.  The laminating machines were paper converting lines that uyilized either gas convection ovens or steam heating for the drying phase of the lamination process.  I left Lion/Circle in 1998 to start J.L.K. Electronics.

J.L.K. Electronic started as a Television/VCR/DVD Player repair service. I had to supplement my income by accepting work as a commercial/residential electrician.  It was soon evident that the competition was extreme and the fact that it was cheaper to buy new entertainment units, I decided to go back to Lion/Circle in 2003.  At that point in time, Midwest Laminating started moving its operations to a recently acquired location in Alsip, IL.  Practically all of my time was spent in assistng in the move and setting up the electrical systems in the new location.  Much of the time was spent building new control panels for the convection ovens and rebuilding/rewiring machines in their entirety.  The pictures in the left sidebar are 2017 photos of Midwest Laminating.  Clicking on the pictures will open the picture in a new rab.  I left Midwest Laminating in 2007 to work for Modern Drop Forge.

I was hired by Modern Drop Forge hired as a Journeyman Industrial Electrician in January 2007. The equipment used in the forging operations consisted of various hammers and presses in addition to gas-fired and induction furnaces as well as other support equipment of which I required to maintain and service.  In April 2007, I was advanced to Journeyman Electronics Technician.  I was required to service equipment to the component level, assist engineering in the installatiion and testing of prototype circuits and eqiupment, makes changes to PLC programs, etc. in addition to acting as in my prior capacity as an electrician.  I was laid-off in January 2009, when the company prepared to move to Indiana.   In addition to Karel programming for Fanuc robots, I have used RSLogix 500 software for programming and troubleshooting automated systems using Allen-Bradley Micrologix 1000 and SLC 500 lines of PLCs.  I have had the same required duties for other PLCs such as:

  • Allen Bradley PLC-5
  • G.E. Fanuc Series 90-30
  • Siemens/ Texas Instruments 435, 505, and 535
  • G.E. Fanuc PC Jr. and Series One to Series Six

I have also installed and maintained various types of input devices such as load sensors,  inductive and optical sensors manufactured by Microswitch and Omron.  This also includes output devices such as electronic interfaces,  motor control centers, relays and solenoids manufactured by Allen-Bradley, Cutler-Hammer, Omron, Parker, and Vickers.

I am thoroughly trained and experienced in the installation and maintenance of Honeywell and Rockwell International HVAC and thermal controls and sensors which are among the most widely used in industry today.

During the period of the lay-off to the present, I went back to school to obtain several certificates and a degree in Management Information Technology as well as several certificates in welding and non-destructive testing.  These certificates are presented in the other pages of this site.
