20.500.12556/RUL-186928 Avtomatizacija polnilne linije za čokoladna polnila Automation of a chocolate filling preparation line V tem diplomskem delu je predstavljena avtomatizacija polnilne linije za čokoladna polnila v podjetju Incom d.o.o. Linija je namenjena avtomatski pripravi mešanice čokoladne osnove in polnil, ki se po celotnem procesu prenese v temperirno posodo za nadaljnjo obdelavo. Proces avtomatizacije vključuje polnjenje in praznjenje glavnega bazena čokoladne osnove, ki se nadzoruje s tehtnico s histerezno logiko, dodajanje polnil iz soda preko črpalke ter mešanje obeh komponent v linijskem mešalniku. Glavni cilj dela je bil zasnovati in realizirati krmilni sistem, ki zagotavlja varno, ponovljivo in nadzorovano delovanje sekvence polnjenja, praznjenja in mešanja. Pri izvedbi projekta je bil uporabljen programirljivi logični krmilnik Siemens S7-1200 v povezavi z vmesnikom HMI SIMATIC TP900 Comfort. Programska logika je bila razvita v okolju TIA Portal in vključuje krmiljenje sekvence polnjenja in praznjenja glavnega bazena čokoladne osnove, delovanje linijskega mešalnika, stopničasto regulacijo hitrosti črpalke za polnila namesto klasične regulacije PID, alarmni sistem ter masni totalizator za spremljanje porabe čokoladne osnove in polnil. Na vmesniku HMI so bili izdelani zasloni za nadzor procesa, upravljanje uporabnikov preko sistema RFID, ustvarjanje in izvajanje receptur, spremljanje alarmov ter nastavljanje procesnih parametrov. Rezultati dela kažejo, da razvit krmilni sistem omogoča stabilno in ponovljivo delovanje polnilne linije ter pregledno spremljanje procesa preko vmesnika HMI. Stopničasta regulacija se je izkazala kot ustrezna alternativa klasični regulaciji PID za dano aplikacijo. Realizirana rešitev polnilne linije omogoča tudi nadaljnje nadgradnje in izboljšave. This thesis presents the automation of a filling line for chocolate fillings at the company Incom d.o.o. The line is intended for the automatic preparation of a mixture of chocolate base and fillings, which is transferred to a tempering vessel for further processing once the process is complete. The automation process includes filling and emptying the main chocolate base basin, controlled by a weighing scale using hysteresis logic, the addition of fillings from a barrel via a pump, and mixing both components in an inline mixer. The main goal of the work was to design and implement a control system that ensures safe, repeatable and controlled operation of the filling, emptying and mixing sequence. A Siemens S7-1200 programmable logic controller was used for the implementation of the project, together with a SIMATIC TP900 Comfort HMI. The program logic was developed in the TIA Portal environment and includes control of the filling and emptying sequence of the main chocolate base basin, operation of the inline mixer, step-based regulation of the filling pump speed instead of conventional PID control, an alarm system, and a mass totalizer for monitoring the consumption of the chocolate base and fillings. Several screens were created on the HMI for process monitoring, user management via an RFID system, creating and running recipes, monitoring alarms, and setting process parameters. The results of the work show that the developed control system enables stable and repeatable operation of the filling line, as well as transparent process monitoring via the HMI. The step-based regulation proved to be a suitable alternative to conventional PID control for the given application. The implemented solution for the entire filling line also allows for further upgrades and improvements. avtomatizacija polnilna linija programirljivi logični krmilnik TIA portal HMI vmesnik automation filling line programmable logic controller TIA portal HMI true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-07 11:00:35 2026-09-07 11:00:39 2026-09-14 13:35:48 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63399 291027715 Zizmond_Matevz_-_Avtomatizacija_polnilne_linije_za_cokoladna_polnila.pdf Zizmond_Matevz_-_Avtomatizacija_polnilne_linije_za_cokoladna_polnila.pdf 1 14620874627104816D434F3C379F386B 62d962f918935ebb392e51706ca44ddc8b44f44bac9bb2bb7d55630e0f4e8649 960145c9-aa9a-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246321 Fakulteta za elektrotehniko 0 0 0
