Manipulator of pack
Raba, Milan ; Čermák, Jan (referee) ; Brandejs, Jan (advisor)
This work is about construcion of a manipulator to be used in paper manufacturing. The manipulator is desinged to turn a package of cellulose placed on a roller conveyor. Turning of the package is necessary for unwrapping and cleaness control of cellulose. Design was made based on analytical calculation and was verified using computer simulation. Pneumatic valves and an electric motor were utilized in the manipulator. The manipulator operates automatically.

Test stand for testing of frame and fork of scooter
Kostka, Marek ; Klapka, Milan (referee) ; Brandejs, Jan (advisor)
The aim of this bachelor thesis is construction design of the testing station for tests of cyclical straining of the frame and fork of the footbike in loading by men in weight from 50 to 150 kg and in kick frequency from 10 to 120 kicks per minute. The format of this work is divided into four main parts. In the first part is this work orientated to actual demands of the footbike. In this part is also described construction design and solution of other testing stations. In other part of this work is accomplished analysis of powers which influent footbike and there are defined particular parameters for testing station. In the third part is described possible approach to solution of testing station and to particular contructional nodes. Last part of this work talks about the resulting proposal of constructional design of the testing station.

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.

Folding mechanism for mobile satellite antenna
Buchta, Tomáš ; Koutecký, Tomáš (referee) ; Brandejs, Jan (advisor)
The aim of this bachelor thesis is the design and construction of a manipulating mechanism for a satellite antenna, mainly for use on vehicles that will be able to work even in adverse weather conditions. The design and manufacturing of the device should provide sufficient positioning accuracy and toughness of the structure. Since this is a prototype therefore the design solutions should be chosen with regard to simplicity of production.

Reversing cross for flexo printing machine
Falta, Jan ; Mazal, Pavel (referee) ; Brandejs, Jan (advisor)
The aim of this work is to develop a new concept of the reversing cross for flexo printing machine SomaFlex Optima. Work includes a description of the machine, the basic description of the principle of flexography. There is explained the principle of turning the material, the current method of supplying air to the air cushion and the difference between the blower and compressor as an air source for the air cushion. Conceptual solution includes two variants, namely vertical and horizontal position of turning bars. For each alternative are described its advantages and disadvantages.

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.
