Lintkonveieri projekteerimine kaubaalustele

Käesoleva lõputöö eesmärk oli projekteerida standardiseeritud lintkonveier ettevõttes Windak OÜ toodetavatele kaablikerimisliinidele ja uurida selle majanduslikku mõju. Lintkonveieri projekteerimise vajadus tekkis erinevustestUSA-s ja Euroopas kasutatavate kaubalustesuurustevahel ningkonveiersüsteemide kõrgetestsisseostuhindadest,mis ei olnudettevõttelemajanduslikultkasumlikud. Lisaks ei ole hetkel kasutatavate rull-ja kettkonveieritega võimalikklientidele paindlikku lahendustpakkuda.Lõputöö tulemusena projekteeriti pakkemasinale kaubaaluste transportimiseks lintkonveier. Konveieri projekteerimiseks disainiti sellele raam, pidades silmas olemasolevaid konveiereid, et selle välimus oleks võimalikult sarnane hetkel kasutusel olevate konveiersüsteemidega. Lisaks tuli sellele valida lint, leida sobivad ketirattad,võll ja mootor. Raami sobivuse valideerimiseks teostati sellele FEM-analüüs, mille tulemusena selgus, et raam on piisavalt jäik, et taluda sellele mõjuvat koormust ning püsivat deformatsiooni konstruktsioonile ei teki.Detailide maksumuse ja tööjõukulude põhjal kujunes projekteeritud lintkonveieri omahinnaks 4870 €.Selgus, et lintkonveierit on majanduslikult otstarbekam ettevõttel endal valmistada, sest ostutoote soetamismaksumus on ligikaudu 18 000 € ning projekteeritud lintkonveieri müügist on võimaliküle 10000 € kasumit teenida.Võib järeldada, et töö eesmärk on täidetud, sest projekteeritud lintkonveierit on võimalik olemasolevatespakkemasinateserinevate suurustega kaubaaluste transportimiseks kasutada ja lahendus osutus majanduslikult otstarbekaks.

The aim of this final thesis Design of Belt Conveyor System for Pallets was to design a standardized belt conveyor for the cable winding lines produced by Windak OÜ and to analyzeits economic impact. The need for designing a belt conveyor arose from differences in the sizes of pallets used in the USA and Europe, as well as the high purchase prices of conveyor systems, which were not economically profitable for the company. In addition, the currently used roller and chain conveyors do not provide flexible solutions for customers.As a result of this thesis, a belt conveyor was designed for transporting pallets to be used inthe Windakpackaging machines. A frame was designed for the conveyor, consideringthe existing conveyors so that its appearance would be as similar as possible to the currently used conveyor systems. In addition, the belt had to be chosenand the correctsprockets, shaft,and motor had to be found. To validate the suitability of the frame, FEM analysis was performed, which showed that the frame is rigid enough to withstand the load andthe structure of the conveyor did not experience any permanent deformation.Based on the cost of details and labor, the price of the designed belt conveyor was determined to be 4,870 €. It was found that it is economically more profitablefor the company to manufacture the belt conveyor in-house,as the purchase cost of a ready-made product is approximately €18,000 and it is possible to make a profit of over €10,000 from the sale of the designed belt conveyor.It can be concluded that the aim of the thesis has been fulfilled, as the designed belt conveyor can be used for transporting pallets of different sizes in existing packaging machines, and the solution proved to be economically profitable.
