Slitter rewinder control
Růžička, Kamil ; Pásek, Jan (referee) ; Richter, Miloslav (advisor)
This diploma thesis deals with the control of unwinding and winding tension sections on the slitter rewinder for packaging material. The essay was created in collaboration with SOMA company, which provided a machine for testing and measuring. The theoretical part describes the function of bitter rewinder, possible mechanical approaches of control the tension sections, and real mechanics of control on our machine. The next part explores selected hardware and its use on the rewinder. Further chapters are focused on the individual measuring chains, calibration, computations of required quantities and control algorithms. The last part compares the theoretical and measured values and evaluates the results of this essay.

Control of dry wall tape (DWT) rewinder
Bis, Jan ; Jirgl, Miroslav (referee) ; Pásek, Jan (advisor)
This thesis deals with a description of the industrial machine of the DWT (drywall tape) rewinder. The winder rewinds and cuts the drywall tape tape into smaller tapes, that are then sold. The first part contains a description of the winder, its structure and functions of its individual parts. The second part contains a description of the control system and the power wiring of winder. The next section contains a description of programming and setting of PLC, frequency inverters, and touch panel. Some modifications are then described when putting the winder into operation. The winder has been successfully implemented and built into a continuous shift operation. However, the development of the rewinder continues to improve its features and user-friendliness.
