Avtomatizacija pomika vertikalnih valjčnic

PAJEK, ROK (author), Petkovšek, Marko (mentor)

V diplomski nalogi sem opisal projekt avtomatizacije pomika vertikalnih valjčnic, ki so sestavni del proizvodne linije za izdelavo lahkih gradbenih plošč v podjetju Trimo. Pri izvedbi sem uporabil obstoječi krmilnik SIEMENS CPU318-2. Merjenje pomika se izvaja s pomočjo merilnih letev MTS Temposonics. Končne pozicije se zaznava s pomočjo induktivnih stikal, pomik vertikalnih valjčnic pa poganja sistem SEW, ki je sestavljen iz frekvenčnega pretvornika, motorja in reduktorja. Najprej sem v programskem okolju SIMATIC Manager izdelal program za krmilnik, s katerim sem preveril delovanje merilne letve. V nadaljevanju sem izdelal tudi načrt vseh električnih povezav. S pomočjo tega načrta smo na linijo vgradili potrebne elemente. Po zagonu linije je bilo potrebnih nekaj modifikacij mojega programa. Sedaj se pomik vertikalnih valjčnic upravlja preko vmesnika SCADA, ki je prav tako del obstoječega sistema na tej liniji.

• Title: Automatization of vertical rollers displacement

Abstract

In my diploma, I described the project of automation of vertical rollers, which are integrated in a larger production line for light construction panels in company Trimo. In the project, I used the existing PLC controller SIEMENS CPU318-2. Position measuring is carried out by MTS Temposonics measuring rods. The end positions are sensed by inductive switches. Movement of the vertical rollers is achieved by SEW drive system, which consists of a frequency inverter, induction motor and a gearbox. Firstly, I wrote a program (in the programming environment SIMATIC Manager) for the PLC, which was used to test the functioning of the measuring rod. Then I made a plan of all electrical connections. With the help of this plan we installed all the necessary elements in the production line. For proper functioning, some modifications of my program were done. Now the position of vertical rollers is controlled through the SCADA interface, which is also a part of the existing control system on this line.
