20.500.12556/DKUM-96073 Optimizacija napenjalca pri postopku navijanja vlaken magistrsko delo Optimization of the tensioner in the fiber winding process V magistrskem delu je obravnavana optimizacija naprave za napenjanje vlaken v postopku filamentnega navijanja, ki predstavlja ključno tehnologijo pri izdelavi kompozitnih cevi iz steklenih in bazaltnih vlaken. Izvedena je bila poglobljena analiza obstoječe naprave, kjer so bile identificirane njene ključne pomanjkljivosti: nizka natančnost merjenja napetosti, omejene možnosti regulacije v realnem času, neprimerna zasnova komponent ter omejena prilagodljivost pri integraciji v proizvodni proces. Na osnovi pregleda sodobnih rešitev na trgu in analize konkurenčnih ponudnikov je bil oblikovan sklop zahtev, ki vključuje funkcionalne, tehnične in varnostne vidike. Poseben poudarek je bil namenjen natančnemu merjenju napetosti s pomočjo obremenitvene celice AST KAP-S, modularni zasnovi konstrukcije, kompaktnosti sistema ter zmožnosti integracije v obstoječo CFW-linijo podjetja Topfibra d. o. o. Proces optimizacije je potekal v več iteracijah, kjer so bile razvite štiri konceptne zasnove naprave. Vsaka faza razvoja je prinesla pomembne izboljšave, kot so optimizacija razporeditve aktuatorjev, povečanje mehanske togosti, izboljšana dostopnost za vzdrževanje ter vključitev nosilnih plošč za namestitev merilnih in vodilnih elementov. Končna rešitev vključuje kompaktno in robustno konstrukcijo z integriranim merilnim sistemom in pripravo na implementacijo zaprte regulacijske zanke s PID-regulacijo. V zaključnem delu je izvedena tudi ekonomska analiza investicije, kjer so ocenjeni stroški optimizacije, vzdrževanja in izpadov v primerjavi z obstoječim sistemom. Rezultati kažejo na ekonomsko upravičenost investicije ob upoštevanju dolgoročnih prihrankov in povečanja proizvodne stabilnosti. Magistrsko delo tako združuje teoretične osnove, analizo obstoječega stanja, optimizacijski razvoj in ekonomsko vrednotenje, kar prispeva k celovitemu izboljšanju proizvodnega procesa podjetja Topfibra d. o. o. This master's thesis addresses the optimisation of the fibre tensioning device used in the filament winding process, a key technology in the production of composite pipes made of glass and basalt fibres. An in-depth analysis of the existing device was conducted, identifying several critical shortcomings: low accuracy of tension measurement, limited real-time regulation capabilities, inadequate component design, and limited flexibility for integration into the production process. Based on a review of contemporary market solutions and an analysis of competing suppliers, a comprehensive set of requirements was defined, covering functional, technical, and safety aspects. Special attention was dedicated to precise tension measurement using the AST KAP-S load cell, the modular design of the structure, the compactness of the system, and its compatibility with the existing CFW line at Topfibra d. o. o. The optimisation process was carried out through several iterations, resulting in the development of four conceptual design solutions. Each phase brought notable improvements, such as the optimisation of actuator layout, increased mechanical rigidity, improved accessibility for maintenance, and the inclusion of support plates for mounting measurement and guiding components. The final solution features a compact and robust structure with an integrated measurement system and preparation for the implementation of a closed-loop PID control system. In the concluding part of the thesis, an economic analysis of the investment was conducted, evaluating optimisation costs, maintenance expenses, and downtime in comparison with the existing system. The results demonstrate the economic justification of the investment, taking into account long-term savings and increased production stability. This master's thesis thus combines theoretical foundations, an analysis of the existing state, optimisation development, and economic evaluation, contributing to a comprehensive improvement of the production process at Topfibra d. o. o.
