Storage stacker for full pallets of the FIFO system
Čechmánek, Lukáš ; Bukovský, Radim (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deals with the design of a full pallet storage stacker using the FIFO method. The first part of the thesis contains a research analysis of similar competitive solutions. This is followed by a description of the created conceptual design of the storage stacker. The design includes the choice of speeds and accelerations of stacker movements, which are necessary for the calculations of the tilting, lifting and traveling mechanism. Another part of the thesis is the strength check of the lifting carriage frame. The attachment consists of the drawing documentation of the designed device.

Travel unit of stacks stackers
Pavelka, Roman ; Kozok, Zbigněv (referee) ; Škopán, Miroslav (advisor)
This master thesis deals with the design of stack stackers travel mechanism for height from 10m to 44m. Next it deals with the strength analysis travel unit for one-pillar stacker for hight of pillar 26m. In the first part is done brief introduction to problems of stocking and description basic parts of stack stacker. After that follows structural design, calculation of travel wheel, drive, shaft and bearings. In the second part of thesis is deals travel unit frame, calculation of transport capacity and is done safety concept of stack stackers. An integral part of the thesis is drawing documentation.

Design of the upper beam two columned shelf stacker
Kuděla, Jan ; Kozok, Zbigněv (referee) ; Škopán, Miroslav (advisor)
This master thesis deals with a concept of two columned shelf stacker’s upper beam. The first part contains a research of storage systems used in logistics and a description of the shelf stack’s basic parts. The second part is dedicated to the draft of the pulley arrangement with a rope calculation, pulleys and shafts, in the same the draft of the pulley attachment to the rope leading to the counterweights. It is followed by the concept of the couple winch drive ensues synchronized with the electronic cardan. The final part depicts the dynamic analysis of the lifting truck’s movement in the dependence on the load size and distribution respecting the dynamic effect of the counterweight act.

Shelf stacker for storing pallets in an automatic store
Javůrek, František ; Kozok, Zbigněv (referee) ; Pokorný, Přemysl (advisor)
Target of the submitted work was a proposal of a new type of shelf stackers in the range from 8 to 36 m that are working in fully automated warehouses. By using a fully automated storage system all human supervision in ordering pallets in a warehouse are canceled and everything is taken over by the control system. These stores are very efficient and save both time and money. With regard to safety requirements, regular inspections should be provided to the system. At the beginning of this work, there was done a short introduction to the particular study including the description of basic parts of the shelf stackers. Consequently, there were done relevant computations for the drag device and its drive, drives for the travel and the finite method was used to the stress analysis of the mast shelf stacker. In the last part of this thesis is done a safety concept.

Design of PLC program for linear motor drive
Kolbinger, Ondřej ; Štěpánek, Vojtěch (referee) ; Pruša, Radomír (advisor)
In its first part, this work deals with the study of various types of linear motors and the principle of their operation. The next part deals with programmable logic controllers, their composition and the possibilities of programming languages. In addition, it deals with the requirements that are placed on shelf stackers. Related to this is the part that deals with the individual parts of the stackers. The second part of this work then focuses on the practical design of two PLC programs for driving with a linear motor and the way in which they were solved by parts of the program. In connection with this, I explain the partial parts of the assembly on which one of the programs was tested and describe the work with Unidrive M Connect and Machine Control Studio.

Optimization of the assembly process of rack stackers in a manufacturing company
Selzer, Tomáš ; Macíčková, Zdeňka (referee) ; Píška, Miroslav (advisor)
This diploma thesis discusses the matter of an innovative assembly process of rack stackers within a manufacturing company. This type of assembly is currently executed in a stationary manner, meaning that the individual parts and subassemblies are being assembled at several designated stationary workplaces. This results in a high number of worked-on units and a fluctuating rate of unit completion. Therefore, the main aim is to develop and establish a new assembly process concept, which will increase the production capacity, lower the number of work-in-progress units and improve the fluency of the assembly process. The thesis is divided into a theoretical and a practical part. The former part’s introduction serves to make one familiar with the chosen manufacturing firm and its products. Next, individual theoretical solutions followed by their applications for the firm are described. These are as a result of a thorough research conducted on scientific literature, mainly scientific articles. The second half of the thesis is concerned with an analysis of the current state of assembly process, where the key efficiency factors are identified, as well as with the process of designing an assembly line, using the One-Piece Flow concept, meaning the workers are only working on a single unit and the parts and subassemblies are moved between the operations. The concept design includes: a selection of suitable types of stackers, an estimation of an appropriate takt time, an analysis of the current assembly process, a determination of the time necessary for assembly and a design of three possible layout solutions, from which, based on multiple criteria, the most suitable one was chosen.

The storage stacker for machine tools
Hradil, Martin ; Bukovský, Radim (referee) ; Kašpárek, Jaroslav (advisor)
In these days, on over the world, we ca find a huge CNC centres which are more and more often completely automatized. There is no necessity of human intervention to change or stock the machining tools. All these operations are made thanks of robots and manipulators to economize time and money. Target of this these is conception of the mobile storage stacker which can be made and then transported to the place of usage in a 40ft sea container. After transportation the stacker is completelly reade to use. Thanks of this concept, we gain universal storage stacker for differents conditions without necessity of new concepts and and solutions for each CNC centre.

Computer simulation of an automated rack stacker
Chalupa, Pavel ; Juříček, Martin (referee) ; Hromková, Ivana (advisor)
The aim of this bachelor's thesis is to create a simulation model of the High Bay Storage using the simulation program Tecnomatix Plant Simulation. In the first part of this thesis, a software analysis was carried out, Plant Simulation was selected to process the problematics of discrete simulation of production systems. This is followed by an explanation of the terms model, simulation run and system. Additionally, discrete and continuous simulations are compared in this part of the thesis. This section also explains the problematics of High Bay Storage, including their automation options, stackers and storage stocks management. Palletization together with different types of automated storage and retrieval systems are discussed as well. The second part of this thesis contains a simulation model of the warehouse with multiple types of storage and retrieval systems. All these types are evaluated, and the most effective option is selected.
