Innovation of the bucket elevator
Hála, Ondřej ; Frýza, Josef (referee) ; Brandejs, Jan (advisor)
The bachelor thesis deals with the innovation of the bucket elevator. The thesis is focused on design modification of the elevator in the areas where the transported material is settled. Settled material causes decay and subsequent contamination of the fresh material. Main purpose of this paper is to propose design solution to improve cleaning of the feed boot of the bucket elevator. The next innovation deals with the modification of the marking system and efficient series of the elevators.

Measurement and Evaluation of Axis Straightness of Rotary Forgings using Photogrammetry and Image Analysis
Zatočilová, Aneta ; Druckmüller, Miloslav (referee) ; Matula, Pavel (referee) ; Morovič,, Ladislav (referee) ; Brandejs, Jan (advisor)
The thesis deals with methodology proposal for shape and dimension measurement of rotationally symmetric forgings. Most of available non-contact systems are not possible to use for this purpose, mainly due to high temperatures and large dimensions of forgings. Only a few commercial systems which are designed for this specific measurement are currently in the market. These systems are based on a principle of evaluating time response of posted modulated signal. However, scientific literature shows also other approaches to the measurement, which are based on principle of triangulation and methods of image analysis. Advantage of systems based on these principles should be especially measurement speed and significantly lower price. The paper describes current state of research and development in this area and proposes a new approach which is based on passive photogrammetry and image analysis. The core of the work is devoted to the design of partial methods and their implementation in the Matlab programming language. Functionality of the methodology and the software has been verified by measuring cylindrical tubes of small dimensions in laboratory conditions. The designed methods were discussed and evaluated based on statistical analysis of the measurement results, and further steps to increase the accuracy and reduce the spread of results were suggested. Optimization and further development of this methodology could lead to the design a professional measuring system intended for this specific application.

Mechanical design of mobile camera system via electric drive
Bosák, Dalibor ; Brandejs, Jan (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with an overview of accessories for a camera movement and mechanical design of a mobile camera crane via electric drive. In the construction part of the thesis are primarily brought conception designs of a camera crane including stress analysis in each places of the crane and then the proposal itself according to the chosen concept. There are shown solutions of individual parts of the camera crane with their description and views. In the end of the thesis are resumed the advantages of the design and economical analysis including the prices of each components and the whole crane.

Locking device for sliding roofing of the swimming pool
Sedláček, Jan ; Hort, Filip (referee) ; Brandejs, Jan (advisor)
In first part, this bachelor thesis tries to summary possibilities of covering and roofing of swimming pool. It deals in detail with the most expanded type of swimming pool roofing – the sliding roofing. The analysis of roofing efficiency has been performed and the primary positivities of this type of roofing have been founded. The next section describes constituent elements of sliding roofing. The second part of bachelor thesis focuses on design of locking device for sliding roofing of the swimming pool. First, the proposal of solutions was done. The proposal is based on two solutions. The first proposal is based on the idea of railroad conduction in all segments, the second proposal suggest the railrod conduction only for the biggest segment, the other segments wheel on the floor. For the design was chosen second proposal, created a 3D model and drawn the assembly drawing.

Horizontal grill
Horák, Vojtěch ; Krčma, Martin (referee) ; Brandejs, Jan (advisor)
This barchelor's thesis deals with the construction of a homemade horizontal piglet grill with an electric propulsion. The grill is designed for solid fuel in the form of timber or charcoal. It is proportioned for 50kg. The research part consists of a description of the main types of grills and their advantages and disadvantages. The constructive part deals with the solution of the constructional problemes, documented by calculations. This construction is considered to be made with lowest expenses. Part of this work is also a continuous photodocumentation, which captures the whole process of the construction progress. At the end of the thesis there is the estimation of production costs.

Innovation of chip conveyor for cutting machine
Kočica, Martin ; Kubík, Michal (referee) ; Brandejs, Jan (advisor)
The aim of this project is the design modification of existing outdated chip conveyor for the lathe SPT 32 NC, owned by Slovácké strojírny OJSC factory 1 Strojírny Uherský Brod. The work is divided into acquaintance with the problem of chip conveyor and the requirements that are placed on the conveyor. The thesis summarizes possible design solutions, of which is chosen the best design solution. Followed by calculations dimensions, choice of materials and semifinished products for creating drawings. The primary input for the work is existing conveyor frame. All dimensions and functional members were chosen with regard to the parameters of the conveyor frame, which will be modified at least. The output is a complete drawing documentation and accompanying report.
