Abstract (en)
[origin: EP1840250A2] A method for controlling work vehicles in a yarn processing apparatus allows work vehicles to travel and move efficiently to execute service processes on units with a high work efficiency even if two units located at an mutually interfering position issue service processes, respectively. The area in which approaching work vehicles 4a, 4b may interfere with each other and fail to simultaneously execute an operational process is defined as the "interfering area" on the basis of the width dimensions of the unit 2 and the work vehicles 4a, 4b. When the two units 2 simultaneously issue service process requests, respectively, the method determines, before traveling movement of the work vehicles 4a, 4b, whether the units 2 are in the mutual interference state, on the basis of the interfering area. Upon determining that the units 2 are in the mutual interference state, the method measures the distances from the current positions of the work vehicles 4a, 4b to the respective process requesting units 2, 2. Then, one of the work vehicles 4a, 4b which is closer to the corresponding process requesting unit 2 is preferentially allowed to execute a service process.
