Drive Vertical Saddle of Machining Centre by Linear Motor
Zapletal, Radek ; Andrýsek, Radim (referee) ; Foller, Bronislav (advisor)
The diploma dissertation deals with the mechanism of vertical movement of a saddle of high-speed machining centre which is made by the Trimill company. The movement of vertical alloy saddle is solved by ball screw. The solution could be improved by replacing the ball screw by linear motor. This will dramatically improve the dynamics of the movement of the vertical saddle. In addition, if the weight is compensated by pneumatic relief and the construction is welded, the dynamics will further improve.

Automatic barman
Podrabský, Tomáš ; Horna, Jakub (referee) ; Štohl, Radek (advisor)
I was working on a project of the automated bartender, whose construction has already been done. At the beginning I had to acquaint with construction and understand how it should work. I created the software in developmental environment CoDeSys in version 2.3 and later in version 3.5. Both of them allows the program creation, as well as visualization and online monitoring of PLC operation and debugging. PLC communicates via AS-interface. The aim of this project was to create fully functional application for barman. PLC program is structured as a state machine, which is ideal for this application. State machine is written in the developmental environment in language SFC and its individual steps in LD, ST, or FBD. I focused on simplicity and clarity of the program, in which I tried to incorporate as many features as possible. I managed to create a program that is able to tap one of the 4 or mix of any number of drinks. It can be also said that the operator doesn't want a full glass, but fewer doses than the maximum. The main acquisition for me was the fact that I was able to solve the problem independently, using the programmable controller on a real system, which gave me lots of new skills. The result of this work is fully functional automated barman including visualization that shows the status of sensors, the number of doses for individual drinks and allows to control the whole system and check error messages.

Single purpose machine for automotive parts assembly
Trávníček, Ivo ; Hrbáček, Jan (referee) ; Krejsa, Jiří (advisor)
Práce se zabývá návrhem jednoúčelového plně automatického zařízení pro automobilový průmysl, které dávkuje silikonovou směs do pouzdra snímače. V první části práce je řešen návrh mechanické části zařízení, zejména manipulátoru pro polohování dávkovací hlavy. K pohonu manipulátoru je využito pneumatických prvků, které jsou řízeny elektrickými signály. Druhá část práce se zabývá řízením stroje, které je realizováno pomocí PLC systému. Obsluha může ovládat zařízení nebo sledovat aktuální stav na dotykovém panelu. V závěru práce je prezentováno skutečné provedení zařízení a propojení s výrobní linkou.

Press model included Safety function
Mikyska, Kamil ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This thesis deal with creation of learning press model included safety function. Hardware implementation and ordering particular components is described. Designed service program is explained. This program is created in development system RS - logix 5000 by ladder diagram language. Panel view is used for better transparent of the process. Service program for this panel is created in development system RS - ViewStudio. Every possibilities of model usage are described.
