Design of the "twist off" lid tightening machine
Jirásek, Vojtěch ; Tůma, Jiří (referee) ; Hermanský, Dominik (advisor)
In the thesis is dealt with the structural design of a machine (and its structural components) for closing jars with twist-off lids. Common design solutions used in practice and their characteristics are mentioned. The selection of structural elements suitable for semi-automatic production was made out of these. The tightening torque of the chosen lids was determined to choose the tightening drive. The required clamping force was calculated to ensure the transfer of the tightening torque without undesirable slippage of the jar or lid, then a suitable linear pneumatic drive was chosen. The required time to complete each operation during sealing was calculated to check the production capacity.

Design of a machine for filling and closing tubes
Doležal, David ; Tůma, Zdeněk (referee) ; Hermanský, Dominik (advisor)
The master's thesis on the topic " Design of a machine for filling and closing tubes " addresses the construction issues of the specified device. The introductory part includes a systematic analysis of the task, which then guides the execution of the thesis. The literature review section lists manufacturers of filling equipment and describes various types of filling devices. A plastic tube and the filling mixture were selected. The dimensions of the tube were chosen to be 35 mm in diameter and 165 mm in height. Toothpaste was selected as the mixture. The next part of the thesis deals with the design of the filling device, where emphasis was placed on the simplicity of manufacturing and ease of assembly. The device was divided into individual functional units, which are described in the document. In conclusion, an evaluation of the filling device assembly is presented, including recommendations for possible improvements in the design. The result of the thesis is a 3D model of the filling device for plastic tubes.

Design of an automatic line for filling and sealing cups
Denk, Daniel ; Tůma, Jiří (referee) ; Hermanský, Dominik (advisor)
The aim of this diploma thesis is the design and structural development of a machine intended for the food industry. The machine fills plastic cups with the mixture, which it then closes with an aluminum lid. The product is marked with a use-by date and stored in an intermediate container. The result of the work is a 3D model of a single-purpose machine developed in the Creo Parametric program, drawing documentation of the machine and selected units.

Design and optimization of a frame for a machine tool
Weigl, František ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This diploma thesis deals with the optimization of the machine tool bed. In the first part of the thesis, individual machine tools and their distribution are briefly described. The following is a description of the influences that affect the static and dynamic properties of the bed, a brief overview of the materials used in the production of machine tools and a short overview of optimization methods. The second part of the work focuses on the creation of a model of the bed, which is used for mathematical optimization using FEM in the ANSYS Workbench. This serves to find the optimal input parameters of the bed, which will improve the static and dynamic properties of the bed. The optimization continues with changing the topology of the bed and using alternative materials. The result of this work is four optimized models, which are compared with the original configuration.

Passive compensation of a thermal deformation for a machine tool
Šabart, Adam ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This master thesis deals with passive compensation of a thermal deformation for a binder of portal machining center. The problem is solved by computational modeling with finite element method using ANSYS Workbench software. Afterwards mathematical optimization (also using ANSYS Workbench software) is used for finding binder parameters in order to reduce thermal deformation and its weight. The output is two new versions of binder which are compared to the original configuration.

Design of headstock for boring centre
Raszka, Pavel ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The bachelor´s thesis deals with the design of the headstock for the horizontal boring center. In the first part of the thesis, a search is made in the field of boring machines and main parts of boring machine headstock. Based on this theoretical analysis, the input parameters for the calculation of the tension, power and torque characteristics of the headstock are selected. Subsequently, the design of the headstock is done using a 3D model.

Workpiece conveyor
Vaníček, David ; Hermanský, Dominik (referee) ; Dokoupil, Vladimír (advisor)
This master‘s thesis is focused on the design of manipulator for crankshaft handling in flexible production lines. The first part describes the types of production lines and possible ways of inter-operative manipulation. With regard to the suitability of their use, a suitable variant is selected, which is then conceptually processed and verified by technical calculations. The final conclusion is the verification of the design in terms of safety. Part of the master‘s thesis is technical drawing documentation.
