Construction of yarn keeper with mechanic clamp of Air-Jet machine
Jíša, Martin ; Sloupenský,, Jiří (referee) ; Knoflíček, Radek (advisor)
This diploma thesis describes methods of textile fibers treatment, production levels with detailed focus on spinning process especially by Rieter AG in Winterthur, Switzerland, subsidiary company in Usti nad Orlici. Thesis also describes production materials and it’s behavior in relations to production machines. Analysis of the current solution, it’s pros and cons is also done. Setting of requirements of new solution. Creating proposals of design solutions of yarn keeper with mechanic clamp situated on spinning unit on Air-Jet machine. Creating concepts and proposal schemes. After choosing of best possible solution considering production costs, electric consumption during working machine and during active cycle was this variation produce. At the end is review of complete solution and prospective next steps in testing not only in laboratory and prospects of using in field.

Optimalization construction tube lifter of spinner machine
Jeník, Jan ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
The first part of this thesis describes the current technologies of mechanical spin-ning. This is a ring, rotor and air-jet spinning. The product of spinning machines is yarn, the basic material for production textile. The next section describes in detail the current state of the node manipulator lifter tube on spinning machine TORNADO J20, by concern RIETER. It describes the structure, kinematics, duty cycle and requirements for the manipulator. The following optimization options which are described more options for solutions of individual functions of the manipulator, on the end is selected by multi-criteria analysis. The best solution that is elaborate in the next section. The author has created 3-D model optimized lifter tube. Positioning mechanism maintains the current kinematics, it is very similar. But gripper was designed as a passive, thus reduce the load positioning mechanism. Optimization was performed primarily to reduce overall production costs and to reduce weight manipulator. The conclusion is a comparison of current and new solutions. There are also eco-nomic recovery to.
