4. Izdelava in testiranje prototipa sušilne omare : magistrsko deloFran Slemenšek, 2024, master's thesis Abstract: Sušilna omara je namenjena za sušenje in osveževanje mokrega ali suhega perila. Tako se oblačila posušijo, osvežijo in razkužijo s pomočjo pare. Sistem temelji na uporabi izmenjevalnika toplote oz. krajše kompresorja. Ta segreje topel zrak in ga s pomočjo ventilatorja gnanim z BLDC motorjem usmeri v zračni kanal na zadnji strani omare. Voda se prečrpa iz rezervoarja za čisto vodo v parni generator na vrhu omare, kateri upari in usmeri vodno paro v omaro, tako da odstrani gube na oblačilih, prav tako pa jih razkuži. Para kondenzira na dnu omare kjer je zračni usmernik in se s pomočjo črpalke prečrpa v rezervoar z umazano vodo. Sistem ima več različnih nastavitev, kot so samo sušenje, samo uporaba pare, sušenje in para, časovne programe, varnostno zaklepanje, in začetek sušenja z zamikom. Prav tako omara vsebuje WIFI modul, tako da lahko omaro upravljamo preko aplikacije.
Keywords: sušilna omara, zasnova, izdelava prototipa, avtomatizacija, testiranje, sušenje

5. Suitability of test procedures for determining the compatibility of seal materials with ionic hydraulic fluidsDarko Lovrec, Vito Tič, 2024, original scientific article Abstract: The compatibility of seal materials with the working fluid is crucial for the flawless, energysaving, environmentally sustainable, and safe operation of any technical system. This is especially
true for hydraulic systems operating under high operating pressure. The problem of materials
compatibility comes into play when either a new type of seal material or a new type of fluid comes
into use. The paper discusses the research findings regarding material compatibility testing of new
high-tech ionic hydraulic fluids with commonly used seal materials. Due to the completely different
chemical composition of these new fluids compared to the classical mineral-based oil, for these fluids,
there are no standardized testing procedures. In these cases, we can only lean on the Standards
that apply to classical fluids, which can lead to incorrect results. In the forefront of the paper is the
discrepancy between the results obtained by the standardized test, and the test under real operating
conditions. FKM, an excellent material for seals, proved to be the most suitable in the case of using
ionic hydraulic fluid, according to a standardized test. However, it failed in the comparison test
under real operating conditions, as the cylinder leaked. NBR seals proved to be a better solution.
Keywords: ionic hydraulic fluids, seal material compatibility, static and dynamic test, comparison of results, differences, test suitability

7. Avtomatizirano zaznavanje napak pri delovanju pnevmatske postaje : magistrsko deloAndrej Baligač, 2024, master's thesis Abstract: V obravnavanem magistrskem delu je predstavljena samodiagnostika pnevmatske delovne postaje, ki temelji na uporabi tlačnih in pretočnih senzorjev za zaznavanje puščanja komprimiranega zraka. Glede na izhodiščni delovni cikel postaje smo ocenili nadaljnje poškodbe in naprave in s tem povezano puščanje, pri čemer smo zaznavali dodatno količino porabljenega komprimiranega zraka, ali s tem povezane padce tlaka v določenem ciklu obratovanja. Realni podatki delovanja in puščanja pnevmatske postaje so bili pridobljeni s pomočjo krmilnika Beckhoff, medtem ko smo naredili vzporedno simulacijo izgub s pomočjo programa Automation Studio.
Keywords: pnevmatični manipulator, detekcija napak, samodiagnostika, Beckhoff, TwinCAT 3.

8. Ionic hydraulic fluids and seal-material compatibilityDarko Lovrec, Roland Kalb, Vito Tič, 2024, original scientific article Abstract: Manufacturers of hydraulic fluids invest a lot of effort and resources in improving their physico-chemical properties, with the goal of getting as close as possible to the properties of an ideal hydraulic fluid. It should be non- flammable, environmentally friendly, sustainable and should have excellent physical and chemical properties. After decades of development in the field of ionic liquids and the search for an ionic liquid suitable for use in hydraulic systems, ionic hydraulic liquids are now already in industrial use, especially on devices that operate in harsh and risky operating conditions. Since ionic hydraulic fluids are a completely new type of hydraulic fluid, one of the issues is their compatibility with the materials present in the hydraulic components, including all the seals. This paper refers to the process of testing the compatibility of hydraulic seal materials with different types of ionic hydraulic fluids according to the standardized percentages and recommendations, with emphasis on changes in the swell, shrinkage and hardness of the seals. The presented results are a useful guide for selecting suitable seal materials in case of using high-tech ionic hydraulic fluids.

9. Avtomatizacija delovne postaje za etiketiranje v okviru sistema CP Lab : magistrsko deloLuka Tandara, 2023, master's thesis Abstract: Eden od poudarkov koncepta Industrija 4.0 je je digitalna transformacija in avtomatizacija proizvodnih procesov. Tem usmeritvam sledi tudi vsebina magistrskega dela, kjer je v ospredju razvoj procesa avtomatizirane proizvodnje. V ta namen je bil uporabljen laboratorijski sistem CP Lab proizvajalca Festo, pri čemer je bila v ospredju podrobna analiza modula za označevanje izdelkov - etiketiranje. Znotraj programskega okolja TIA Portal smo razvili krmilni program, ki omogoča upravljanje sistema tako v ročnem kot tudi v avtomatiziranem načinu dela, prav tako smo zasnovali uporabniški vmesnik HMI za nadzor in vizualizacijo delovanja sistema. V zaključni fazi projekta je bil modul za etiketiranje uspešno implementiran v celovit sistem CP Lab.
