Avtomatizacija naprave za brušenje NV osnov z implementacijo kazalnikov učinkovitosti

VIDLAK, JAN (avtor), Logar, Vito (mentor)

V magistrskem delu je predstavljen razvoj naprave za čelno brušenje NV osnov. Opisan je celoten razvoj sistema, od izbire komponent do programiranja in njegovega delovanja. Naprava se uporablja na oddelku tehnične keramike v podjetju ETI d. o. o., s katero se posodablja in avtomatizira obstoječa ročna naprava. Naloga je razdeljena na dva dela, v prvem je opis izbranih komponent, v drugem pa je predstavljeno programiranje. V prvem delu magistrske naloge je predstavljen opis naprave in njenih glavnih sestavnih delov. Podrobneje so opisani sestavni deli in komponente v omari ter njihova funkcija delovanja. Napravo se krmili s standardnima komponentama avtomatizacije, in sicer PLK-jem v kombinaciji s HMI-jem. Poleg komponent je podrobneje predstavljen NV talilni element, katerega ohišje je obdelovanec predstavljene naprave. Predstavljen je postopek izdelave NV osnove, opis NV varovalke, njena funkcija v inštalaciji in njene lastnosti. V drugem delu magistrske naloge pa je opisan postopek programiranja naprave. Predstavljeni so deli programov krmilnika in njihova funkcija. Predstavljeni so zasloni HMI in hierarhija zaslonov. Za konec je predstavljena funkcionalnost ključnega kazalnika skupne učinkovitosti naprav (OEE) ter njegova implementacija v napravo in na zaslone HMI. Predstavljeni so tudi rezultati meritev na napravi. Rezultat magistrskega dela od postopka zasnove, izbire komponent, risanja električnega načrta, ožičenja in programiranja naprave je delujoča naprava, ki deluje v skladu z zahtevami naročnika in meri učinkovitost delovanja.

Izvleček

The master’s thesis presents the development of a device for end-grinding of NV fuse bases. The entire development of the system is described, from the selection of components to programming and its operation. The device is used in the technical ceramics department at company ETI d. o. o., to update and automate the existing manual device. Thesis is divided into two parts, the first describing the selected components, and the second presenting the programming. The first part of the master’s thesis describes the device and its main components. The main components of device and parts in the electrical enclosure and their operating function are described in more detail. The device is controlled by standard automation components, namely PLC in combination with HMI. In addition to the components, the NV fuse element is presented in more detail, with its housing serving as the workpiece of the presented device. The process of manufacturing an NV fuse base, their function in the installation and its properties are presented. The second part of the thesis describes the programming process of the device. The parts of the controller programs and their functions are presented. The HMI screens and the hierarchy of the screens are presented. Finally, the functionality of the key indicator of overall equipment effectiveness (OEE) and its implementation in the device and on the HMI screen are presented. Also presented are the results of measurements on the device. The result of the master’s thesis, from the design process, component selection, drawing of the electrical plan, and wiring and programming the device, is a working device that operates according to the client’s requirements and measures performance efficiency.
