Abstract

U ovom radu proveden je pregled literature i zahtjeva na prijenosnike paleta, te pregled postojećih rješenja sa sličnim parametrima. Razmotreni su neki koncepti sa određenim konstrukcijskim rješenjima koja su naknadno vrednovani te je odabran najpovoljniji koncept. Nadalje, razmotrene su različite varijante hodajućih mehanizama te prednosti i nedostaci istih. Zatim su razmotrene različite vearijante Strider hodajućeg mehanizma te su istraženi lokusi raličitih podvarijanti istog. Provedena je konstrukcijska razrada odabranog koncepta transportnog prijenosnika te je izvršen proračun prihvatnog uređaja, podiznog sustava, proračun inverznog koloturnika i odabir lisntog lanca za podizanje. Nadalje, izvršena je FEM analiza nosivog okvira transportnog prijenosnika u programskom paketu Solidworks Simulation. Zatim je provedena simulacija kretanja hodajućeg mehanizma u programskom paketu Solidworks Motion te je proveden odabir pogonskog lanca i motora za transportni prijenosnik. Provjerene su reakcije u pretpostavljenim najviše opterećenim linkovima hodajućeg mehanizma. Naknadno je izvršena kontrola ležajeva i osovina u zglobovima na najviše opterećenim mjestima. Naposlijetku, dan je pregled konstrukcijskog rješenja projekcijama iz programskog paketa Solidworks te sklopnim nacrtom istog.

Abstract (english)

In this paper, a review is made of the literature and requirements for pallet carriers, and a review of existing solutions with similar parameters. Some concepts with certain construction solutions were considered and subsequently evaluated, and the most favorable concept was selected. Furthermore, different variants of walking mechanisms and their advantages and disadvantages are considered. After that, different variants of the Strider walking mechanism were considered, and the loci of different subvariants of the same were investigated. The constructional elaboration of the selected transport transmission concept was carried out, and the calculation of the receiving device, the lifting system, the calculation of the inverse pulley and the selection of the lifting chain were performed. Furthermore, a FEM analysis of the carrier frame of the transport gear in the Solidworks Simulation software package was performed. Then, the simulation of the movement of the walking mechanism in the software package Solidworks Motion was performed, and the selection of the drive chain and motor for the transport gear was performed. Reactions in the assumed most loaded links of the walking mechanism were checked. Subsequently, the bearings and shafts in the joints were inspected at the most loaded places. Finally, an overview of the construction solution is given by projections from the Solidworks software package and a schematic drawing of the same.
