The study of identification and control equipment for material handling in logistics
Vágner, Ladislav ; Pokorný, Přemysl (referee) ; Hloska, Jiří (advisor)
In the first chapter of the barchlor´s thesis focuses on differences and description of the most widely used barcodes and scanners. This chapter describes also newly developed barcode – bocode. The second chapter deals with the radio frequency identification technology. Next chapters are about a production technology of barcodes and explain the functioning principle and possibilities of their usage. In conclusion there is provided a comparison of one–dimensional barcodes, marking technology and types of lasers.

Gravitational roller conveyor for transport of piece material
Navrátil, Zdeněk ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this bachelor work is to project gravitational roller route which has to serve as transporter of the lump material. In this case as transporter of boxes in the production line without positive drive. By force of engaged parameters I have to determine the main dimensions, calculation of the shaft’s stronghold and funkcional calculation. Than implement the design documentation from the calculated values.

Analysis of Calculation of Worm Gear System
Adamík, Jan ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The objective of this document is the calculation and effectivity evaluation of worm gearing. It includes a short description of dimensional and strenght calculation. There is an analysis of gearing effectivity and ratio dependance, material selection is included also. The last part of this document describes questions of the gearing self-locking in dependance on spiral angle.

Travelling Crab
Hrnko, Lukáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The thesis deals with the structural design of the lifting device for the travelling crab with 50,000 kg capacity and lift if the intended use of the crane is in heavy traffic. The thesis includes a proposal for a block-and-tackle which contains suggestion for a suitable diameter and type rope, the strength design of rope drum, the strength design of individual parts of blocks, the choice of a suitable electric motor, the gearbox and finally, the brakes. Strength calculation of the tackle block was the basis for elaboration of drawing documentation for set of tackle block and its selected parts.

Design of a biological organic waste conveyor
Diviš, Přemysl ; Zajíc, Zdeněk (referee) ; Pokorný, Přemysl (advisor)
The master thesis deals with the design of a convex conveyor belt for biological organic waste, with a focus on the mass optimization of its supporting structure. The thesis assignment was developed in cooperation with Bluetech s.r.o. The aim of the work was to perform a functional calculation of the conveyor belt and to complement it with the selection of components. One of the objectives was also to perform a strength analysis of the original supporting structure and to perform its mass optimization from the collected data. The main part of the work is devoted to design the shape of the new support structure, where the resulting weight and the values of the maximum stresses will be lower than the original structure. The conclusion displays summarized results and suggests possible recommendations.
