Tiivistelmä
In this thesis communication between real-time peeling machine simulation and Programmable Logic Controller (PLC) is created. The PLC uses a program which is originally used to control a conventional peeling machine. Thesis describes needed changes in the control program to make the program function with the simulator. The control on the simulation should work so that the simulation imitates the actions of the real machine. Finally, it is shown how this peeling machine simulation could be used from various aspects. One of the goals was to create control for simulation that can be represented on a fair.
The peeling machines are used to peel a 1-4mm thick veneer ribbon from a block of wood. The peeling machine moves the block from block conveyor to lathe spindles in the optimal position to maximize the veneer output. During the peeling various axes are moved simultaneously to support the peeling against forces caused by knife cutting and to improve the quality of the veneer.
The resulting interface uses TCP/IP (Transmission control protocol over internet protocol) communication over Ethernet. The resulting communication interface to simulation initiates various movement commands for each of the axes. The feedback data contains axis status information and relevant sensor status information. Each of the communication clients attempt to send data to its participant every 10 ms. The communication interface works reliably and rapidly enough for logic program need and for interactive use. For future work, the simulation environment could be used to test and develop peeling machine control program.
