20.500.12556/RUL-187157 Projektiranje in avtomatizacija izmetnega sistema za cevni detektor kovin Design and automation of an ejection system for tube metal detectors Izmet pri detektorju kovin služi za ločevanje delcev z vsebino kovine od ustrezne zmesi, ki potuje po sistemu. V sistemu omogoča avtomatsko izločevanje kontaminirane zmesi brez človeškega faktorja, kar je v sodobni industriji zelo iskano in skoraj da nepogrešljivo. Izmet je v grobem sestavljen iz ohišja, lopute, ležajev in pogona lopute. V zaključni nalogi je predstavljen postopek izdelave izmeta. V prvem delu je predstavljena izbira koncepta in materiala, v drugem delu pa način krmiljenja lopute izmeta. V prvem delu smo nanizali tudi nekaj možnih materialov za izdelavo ohišja, nato pa izbrali najprimernejša za našo aplikacijo. Prav tako smo za izbiro pogona izbrali nekaj možnosti ter jih na koncu analizirali in izbrali dve najprimernejši. Izdelali smo tudi finančno analizo za različne materiale izmeta ter za njegove pogone, kar smo predstavili s pomočjo tabel in grafov. Na koncu smo opravili pregled in končno primerjavo različnih konceptov ter ugotovili najugodnejšo in najoptimalnejšo rešitev. V zaključku smo predstavili možnosti za nadgrajevanje in izboljševanje izmeta. The reject mechanism in metal detector serves to separate metal-containing particles from the corresponding mixture that conveyed through the system. The system enables automatic removal of contaminated mixture without the need for human intervention, which is highly sought after and almost indispensable solution in modern industry. The reject mechanism is primarily consisted of housing, flap, bearings, and flap actuation system. This thesis presents the manufacturing process of rejection mechanism. The first part focuses on the conceptual design and material selection, the second part presents the method of the manure flap controlling. First we selected some possible materials for the housing and then evaluated some the most appropriate materials for our application. We also selected a few options for the flap actuation analysed them and chose two the most suitable ones. Economic analysis was performed for the selected housing materials and actuation systems, which was presented using tables and graphical representation. Finally the proposed designing concepts were closely examined and compared to identify the most cost effective and technically optimal solution. The thesis concludes with recommendations for further development and potential improvements of the reject mechanism. detektorji kovin elektro magneti izmeti pnevmatika ulitki zvarjenci rejection mechanism metal detectors pneumatics electro magnets welded castings true false false [Ž.
