Experimental Analysis of Kinematic Quantities on Cam Mechanism
Komenda, Lukáš ; Dočkal, Aleš (referee) ; Zimmerman, Martin (advisor)
This diploma thesis deals with creation of a laboratory task related with analysis of kinematic quantities on cam machanism. A new measuring chain was created as a part of the new laboratory task for analysis of kinematic quantities with use of sensors and signal processing by software LabVIEW. The concept of the laboratory task on a experimental machine was based on knowledge gained from Current State of Knowledge where basic principles of laboratory training and utilization of cam mechanisms in learning were described.

Entwicklung eines Wälzsstoßaggregates zur Erzeugung von Gerad- und Schrägverzahnungen auf flexiblen Bearbeitungszentren
Pavlík, Martin ; Hänel, Thomas (referee) ; Blecha, Petr (advisor)
Diplomová práce představuje návrh agregátu, který umožní rozšíření obráběcího centra o technologii obrážení ozubení odvalovacím způsobem. Principem této jednotky je, převést rotační pohyb vřetene na translační pohyb potřebný pro obrážení při současném dodání odvalovacího pohybu nástroje. Mechanismu zároveň zajišťuje konstantní řeznou rychlost, čímž zvyšuje životnost nástrojů. Jednotka je rozdělena na 5 dílčích mechanismů. U každého z mecha- nismů je analýzou použitelných metod vybrána nejvhodnější varianta. Ta je následně navrh- nuta a případně propočítána. V práci je popsán návrh takového řešení pomocí mechanických převodů a vaček. Tento mechanismus umožňuje obrážení při rychlosti 900 dvojzdvihů/min. při maximální vyvinuté síle 5,5kN. Jednotka je primárně určena pro malovýrobu, jako levnější alternativu k nákupu stroje pro obrážení.

Design of a Unified Mechanism of Shifting and Activation of the Parking Brake
Hagara, Adam ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This bachelor thesis deals with the design of a unified mechanism of shifting and activation of the parking lock. The theoretical part is devoted to a more detailed description of the current shifting mechanisms, synchrosystems and parking lock mechanisms. The practical part starts with the analysis of the movements and positions of the individual mechanisms, followed by conceptual designs and the selection of the most suitable one. This is followed by the final design elaboration, which includes the development of a force analysis and torque calculations. The functionality of the geometry of the designed mechanism is verified by dynamic analysis, while the other components of the mechanism are detailed. Finally, an FEM analysis of the components of the unified mechanism is performed to confirm the functionality of the selected design. The thesis also includes a drawing documentation attached in the annex.

Transfer table electromechanical
Přecechtílek, Pavel ; Malach, František (referee) ; Malášek, Jiří (advisor)
The aim of this thesis is to design a proposal of Transfer table electromechanical earmarked for transporting packs of sheets of tin with balance-sheet of electromechanical and electrohydraulic construction and to make important technical calculations. The introduction contains a description of the used constructional solution with the description of the individual parts of the transfer table and survey used components from different producer. The work includes functional calculations, which mainly includes the design and control of power running and lifting gear, calculate speeds and lift loads, the chain drives and other assemblies Transverse. Conclusion of this work deals with the assessment of the frame strength of the Transfer table using the finite element method. Further the work deals with the assessment of the maximum capacity of the machine and with any design modifications. The work also contains a design documentation, especially the plan of the Transfer table and detailed drawings of the frame and eccentric casters.

Control of packaging machine using Safety PLC
Žiak, Martin ; Novotný, Radek (referee) ; Štohl, Radek (advisor)
This thesis deals with a technology of continuous packaging machine in the beginning from the point of risk assessment and design of necessary measures to reduce the risk as much as it is possible. Here the HRN method was used to quantify every risk factor. Next part documents the implementation of the safety measures and the realization of the safety circuits by using Simatic S7–1500F safety PLC and Shared device functionality. Safety function which is realized in the Sinamics S120 drive is Safe Stop 1. Next, it describes the drive dimensioning and the principle of the drive control. Simotion PLC is discussed in more details and then is used as a motion control master. An approach to the configuration of camming synchronous operation is dealt with in details. Cam design and their realization is documented, too. The thesis also demonstrates the state manager that was implemented in the user program and which is used according to the concept of OMAC state manager. In the end a simple HMI for packaging machine control is described.
