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.

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.

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.

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.

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.
