20.500.12556/RUL-129802 Avtomatizacija linije za proizvodnjo ALU ohišja diferenciala avtomobila Automation of the line for the production of ALU housing for a car differential Pri avtomatizaciji linije se najbolj posvečamo zmanjšanju časa strežnega dela, ki običajno predstavlja ozko grlo v proizvodnji izdelkov. Ročna delovna mesta, pri katerih delavec manipulira s kosi in ročno montira ali vlaga montažne dele, je v proizvodnem procesu najbolje optimirati, saj s tem najhitreje dosežemo višji OEE. Cilj avtomatizacije je tudi zmanjšanje števila delavcev, ki upravljajo s stroji. Pri dizajniranju linije je potrebno upoštevati določene ergonomske in varnostne zahteve, da pri rokovanju s kosi ne pride do poškodb delavca. V okviru diplomske naloge smo izdelali delno avtomatizirano linijo za novo generacijo ALU ohišij diferenciala. Naloga predstavlja glavne razloge za potrebo po avtomatizaciji, da podjetje ostane konkurenčno ostalim na svetovnem trgu. Potrebno je bilo analizirati obstoječe stanje, ki je pokazalo slabe rezultate doseganja zastavljenih ciljev v povezavi z OEE. Odločili smo se, da bomo za novo generacijo ohišij uporabili drugačen način dela in s tem čim bolj zmanjšali ozka grla v proizvodnji. Poskušali smo zasnovati novo proizvodno linijo, na kateri se bosta zaradi velikega števila naročil obdelovali dve generaciji ohišij. Zaradi proizvodnje različnih izdelkov na eni liniji nismo izvedli popolne avtomatizacije, saj bi morali sicer za novejšo generacijo ohišij postaviti povsem novo linijo, kar pa zaradi omejitve s prostorom ni mogoče. Poleg tega bi bile v krajšem časovnem obdobju potrebne večje predelave linije, kar bi povzročilo nove stroške. The automation of production lines is primarily focused on minimising machine loading time, which is usually a bottleneck in the production process. The optimization of manual positions, where workers manually assemble or insert components, is the fastest way to obtain a higher OEE score. Another goal of automation is decreasing the number of workers operating the machines. When constructing a production line, certain ergonomic and safety standards need to be met in order to ensure safe working environment and avoid worker injuries. For this thesis, we constructed a semi-automated line for a new generation of aluminium differential cases. The thesis presents main reasons for automation in order for the company to stay competitive in the global market. The analysis of the existing situation showed that the goals connected to OEE had not been met. We decided to change the production of the new generation of differential cases and thus minimise bottlenecks in the production process. We tried to design a new production line, which, due to a big demand, will be used for two generations of differential cases simultaneously. As the same line will be used to produce different products, we decided against a fully automated line. Due to space limitations, we were unable to design a completely new line for the new generation of differential cases. Furthermore, this would mean significant adjustments for the current generation and new costs in the near future. avtomatizacija robotika ALU ohišje diferenciala proizvodna linija montaža testiranje kakovosti automation robotics ALU housing for car differential production line assembly quality testing true false false [D.
