Namen diplomske naloge je bila izvedba posodobitve odseka transportne proge. V ta namen smo izbrali ustrezno opremo in izvedli vse potrebne nastavitve opreme, zmodelirali nosilce, shematsko prikazali vse vezalne sheme in napisali računalniški program, ki bo s to opremo komuniciral.
Transportna proga prevaža sklade manipulacijskih enot. Manipulacijske enote so s transportnimi etiketami opremljeni plastični zabojniki, v katerih je zapakirano meso in mesni izdelki. Posodobitev smo izvedli z zamenjavo ročnega krmiljenja obstoječe transportne proge s krmiljenjem s pomočjo računalniškega programa in perifernih naprav. Računalniški program, ki je izdelan v programskem jeziku C#, komunicira s perifernimi napravami s pomočjo I/O komunikacijske kartice. Za odčitavanje črtnih kod na transportnih etiketah smo uporabili čitalce črtnih kod. Z njimi zajemamo podatke manipulacijskih enot in preverjamo kakovost izpisa črtnih kod. V primeru nezadovoljive kakovosti izvedemo ponoven izpis etiket in preverimo stanje tiskalnika, ki jih je natisnil. Podatke o manipulacijski enoti izpisujemo na ekran, preverjamo pa tudi konsistentnost podatkov manipulacijskih enot v skladu. Za določitev števila manipulacijskih enot v skladu, ki je lahko največ šest, smo uporabili odsevne senzorje. Enaki senzorji so uporabljeni tudi za zaznavanje položaja sklada v postrojenju. V povezavi z računalniškim programom krmilijo senzorji tudi pnevmatske valje in pogon dodatnega transportnega traku v postrojenju, s tem pa premikajo sklade manipulacijskih enot na želene lokacije.The aim of the thesis was to carry out an upgrade of the section of the conveying path. For this purpose, we have selected the appropriate equipment. Made all the necessary settings of equipment, modeled carriers, schematically shown all wiring diagrams and write a computer program that will communicate with this equipment.
Conveying line is transporting stacks of handling units. Handling units are plastic containers equipped with transport labels. The content of handling units is meat and meat products. Upgrade was accomplished by replacing the manual control of the existing conveyor line with control by a computer program and peripheral devices. A computer program that is made in the C# programming language communicate with peripheral devices via the I / O communication card. To read bar codes on transport labels barcode readers were used. With them handling units data is extracted and quality of printed barcodes is checked. In case of unsatisfied quality re-print of labels is carried out and condition of printer that printed them is checked. Information about handling units is displayed on the screen, and also handling unit’s data consistency in stack is checked. To determine the number of handling units in stack, which can be a maximum of six proximity reflective sensors were used. The same sensors are also used to detect the position of the handling units stack in conveying path. In conjunction with the computer program sensors are also controlling the pneumatic cylinders and operate the additional conveyor belt in the conveying path and thereby move stacks of handling units to the desired location
