Safety assessment of a multifunctional machining centre
Šponiarová, Petra ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The thesis deals with the safety of the multifunctional machining centre of TOS KUŘIM – OS, a.s. In order to assess the safety of the multifunctional machining centre and the safety of the workers involved in its manufacture and assembly, it was first necessary to familiarise ourselves with all the legislation, which includes EU harmonisation and OSH legislation. Harmonised legislation is followed by harmonised technical standards. Compliance with the basic safety requirements of the relevant harmonised standards is a prerequisite for meeting all the requirements of harmonisation legislation. One of the basic requirements before placing a product on the EU market is to carry out a risk analysis. This has been done by correcting and supplementing the risk analysis of the milling machining centre, on whose design the analysed machining centre is based, to meet the requirements of ČSN EN ISO 12100:2011. Particular attention was paid to the production and assembly stage, where several standard production and assembly procedures were selected. Flow charts were drawn up for these selected procedures and a risk analysis was carried out using the FMERA method, which was developed by modifying the FMECA method. For each risk, measures were proposed to ensure that it was reduced to an acceptable level.
Prozessbeschreibung zur Integration von Ecodesign und Maschinensicherheit in den Produktentwicklungsprozess
Božek, Alexandr ; Prostredník, Daniel (referee) ; Blecha, Petr (advisor)
Diplomová práce řeší problematiku vzniku nových požadavků, které jsou kladeny na vývoj nových výrobků s ohledem na budování nízkouhlíkové ekonomiky a zvýšení bezpečnosti výrobků. V první části diplomové práce je popsán stav vědy a techniky v oblasti procesního řízení a následně je popsán životní cyklus obráběcího stroje, s důrazem na vývoj stroje. V druhé části je provedena rešerše v oblasti legislativních požadavků na bezpečnost stroje a na ekodesign stroje do vývoje. V praktické části je provedena analýza hlavních procesů firmy produkující výrobní stroje, a to s důrazem na procesy v oblasti bezpečnosti a ekodesignu. Následně jsou navrženy procesy pro stanovení a ověřování bezpečnosti. Dále práce popisuje metodiku implementace ekodesignu do procesů firmy, která je prezentována na procesech firmy a demonstrována na jednoduchém příkladu vrtačky. Diplomová práce má tak praktický přínos v zavedení subprocesu stanovení a ověření bezpečnostních požadavků a zavedení procesu vývoje produktu v rámci realizace ekodesignu na produktech firmy.

V první části diplomové práce je popsán stav vědy a techniky v oblasti procesního řízení a následně je popsán životní cyklus obráběcího stroje, s důrazem na vývoj stroje, spolu s požadavky a doporučeními ISO 9001:2016 – Systémy managementu kvality – Požadavky. V druhé části je provedena rešerše v oblasti legislativních požadavků na bezpečnost stroje a na ekodesign stroje do vývoje. V praktické části je provedena analýza hlavních procesů firmy TOS KUŘIM – OS, a.s., a to s důrazem na procesy v oblasti bezpečnosti a ekodesignu. Následně jsou navržena zlepšení procesů, do nichž jsou aplikovány subprocesy na stanovení a ověřování bezpečnosti. Do procesů je aplikován subproces umožňující produkci strojů plnících požadavky ekodesignu. Diplomová práce má tak praktický přínos v zavedení automatizovaného subprocesu stanovení a ověření bezpečnostních požadavků a zavedení subprocesu vývoje produktu v rámci budoucích požadavků ekodesignu na produkty firmy TOS KUŘIM – OS, a.s.
Information system for assessment of safety systems according to ČSN EN ISO 12100:2011
Franka, Jakub ; Štohl, Radek (referee) ; Holek, Radovan (advisor)
This thesis is focused on the design and implementation of an information system intended for simplifying work with machine safety systems. It addresses design of the data model, server and client parts of the app and user interface with focus on customizability. The design of the system is based on the norms EN ISO 13849-1 and IEC/EN 62061.
Safety of rack drill machines
Greguš, Peter ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This thesis gives an overview of legislative requirements for safety of machine tools. Based on the information found in the harmonized standards, it sets requirements to rack drill machines.
Information system for assessment of safety systems according to ČSN EN ISO 12100:2011
Janek, Samuel ; Stibor, Karel (referee) ; Holek, Radovan (advisor)
This work deals with the design of an information system that will facilitate the collection of parameters and their further use in the evaluation of security systems. The design will be based mainly on the standards EN ISO 13849 and EN 62061. The resulting application will not contain an initial risk analysis according to the standard EN ISO 12100, but will primarily focus on safety function design and evaluation.
Safety assessment of operator activities for WHN 13 CNC horizontal boring machine
Nohavica, Radek ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma’s thesis deals with the current state of requirements for products resulting from directives of the European Parliament and the European Council. The aim of the thesis is a system analysis of the issue, proposal and justification of the chosen procedure for solving the objectives. Furthermore, the analysis of requirements of current standards and safety analysis related to the work of machine operators in the areas of operation, service and maintenance of horizontal boring machine WHN 13 CNC. The analysis is followed by a proposal for preventive measures for hazards where the value of risks and criticality is unacceptable, leading to their reduction.
Safety sensors in industrial application
Mrkva, Tomáš ; Tůma, Zdeněk (referee) ; Blecha, Radim (advisor)
The aim of this bachelor thesis was to create an overview of offered safety sensors used in automated operation. The sensors are sorted according to the technology they use for their function, is shown the principle of their function, the design variants and ultimately their advantages and uses. The work is divided into three parts. The first part deals generally with machine safety, risk assessment and security level. In the second main part, an overview of individual sensors is processed. The last part slightly touches on the issues of basic control systems.
