Zagon avtomatiziranega skobeljnega stroja Ledinek Multiplan 4V
Klemen Anžel, 2020, undergraduate thesis

Abstract: V diplomskem delu, ki je nastalo v sodelovanju s podjetjem Ledinek Engineering d. o. o., bo predstavljen zagon skobeljnega stroja Ledinek Multiplan 4V. Poudarek bo predvsem na delu, ki se dejansko izvaja na samem stroju. Na začetku bo predstavljen pregled elektronike in nameščene strojne opreme ter predpripravljen programski del. V glavnem delu bodo opisani koraki za zagon stroja in delo na stroju. Pri izdelavi diplomskega dela bosta v veliko pomoč programska paketa TIA Portal in Lenze Easy starter. Po opravljenem postopku mora biti stroj popolnoma funkcionalen, hkrati pa mora zagotavljati kakovostno obdelavo lesnih surovcev.
Keywords: Skobeljni stroj, zagon stroja, Tia Portal, Lenze Easy starter

Representation of Gender in Books for the English Reading Competitions in First and Second Triad of Primary School
Nadja Kotnik, 2018, master's thesis

Abstract: The purpose of the MA thesis was to analyse 21 easy readers in terms of gender. The easy readers included in the analysis appeared on one of the two reading lists for the English reading competitions, EPI reading badge and Bookworms in the academic year 2015/2016. The books were examined with quantitative, qualitative and linguistic analysis with the aim of revealing gender bias and stereotyping in the characterization of male and female characters. An initial overview of the sample revealed great diversity in the sample – almost half the sample represented re-written versions of older books, while the other half were books with original plots or adaptations based on recent films. With regard to quantitative analysis, an underrepresentation of female characters was identified in the text as well as the illustrations. In general, males predominated in every category that we quantitatively analysed, but there were a few books where this was not the case. The qualitative and linguistic analysis provided mixed results. There were some newer easy readers where progress in terms of defying gender stereotypes and discrimination was noticeable, but some older books expressed evident gender bias.
Keywords: gender, easy readers, gender stereotypes, gender roles, English reading competitions, linguistic analysis, content analysis, semiotic analysis

Priprava frekvenčnih pretvornikov in prvi zagon lesnoobdelovalnega stroja superplan 6vr+4f-s200
Primož Zakelšek, 2018, undergraduate thesis

Abstract: Diplomsko delo se nanaša postopek prvega zagona lesnoobdelovalnega stroja, ki ga proizvaja podjetje Ledinek d.o.o. Natančneje bo diplomsko delo obravnavalo pripravo frekvenčnih pretvornikov in zagon stroja, ki ga je potrebno izvesti fizično na stroju na podlagi predhodno zasnovanega programa. Obravnavan bo stroj Superplan z oznako 6VR+4F-S200, ki zajema šest obdelovalnih valjev ter štiri fazne valje, ki lesu dodajo končno obliko. Pred pričetkom zaganjanja je potrebno pravilno pripraviti frekvenčne pretvornike, ki krmilijo elektro motorje. To bomo naredili s pomočjo programskega orodja Lenze easy starter. Za diagnostiko programa se bo uporabljal program podjetja Siemens, ki je zasnovan posebej za namen avtomatizacije proizvodnih procesov in se imenuje TIA portal. Končni produkt ob katerem lahko programer zaključi svoje delo na stroju je pravilno skobljan les, ki ima temu primerno obdelano površino in v mejah tolerance izmerjene dimenzije.
Keywords: Lesnoobdelovalni stroj, PLK, TIA portal, Easy starter.

Povezava virtualnega krmilja z elektro-pnevmatskim transportnim sistemom
Tomaž Rodošek, 2016, undergraduate thesis

Abstract: Procesna avtomatizacija, doba v kateri se nahajamo, omogoča zelo visok standard kvalitetne izdelave, boljšo organizacijo in večjo produktivnost. Zato bi radi preverili učinkovitost različnih načinov vodenja elektro-pnevmatskega transportnega sistema. V večini vodenje poteka s pomočjo programirljivih logičnih krmilnikov – PLK. V diplomski nalogi so predstavljeni in analizirani načini virtualnega vodenja, kjer nam software Fluid Sim opravlja delo vodenja in vizualizacije. Preverili bomo tudi zanesljivost in uporabniški vmesnik računalniškega programa KEPserver OPC, ki skrbi za komunikacijo virtualnega krmilnika z ožičenim delom elektro-pnevmatskega transportnega sistema.
Keywords: Fluid sim, elektropnevmatski sistem, Easy port, S7 200, S7 1200
