PURPOSE:To make the shape small-sized and to decrease power consumption by calculating a speed command signal respectively at the time of impressing the signal of the sensor for travelling or at the time of impressing the signal the sensor for shifting and mounting and impressing the signal to the motor for travelling or the motor for shifting and mounting through a change-over circuit. CONSTITUTION:In trackless trolley which travels on the trackless travelling path and executes the shifting mounting work at the shifting mounting station, the signal from a sensor 3 for travelling at the time of the travelling control is applied to a controller CT 9 through a change-over circuit 11. A CT 9 calculates the speed command of a motor 4 for travelling, inputs the signal to a power unit 10, converts to a motor control signal and through the circuit 11, the control signal from the unit 10 is supplied to the motor 4. At the time of the shifting mounting control, the signal from a sensor 7 for shifting and mounting changes over the circuit 11 and is impressed to the CT 9. The CT 9 calculates the speed command of a motor 8 for shifting and mounting, inputs the signal to the unit 10, converts to the motor control signal, changes over the circuit 11 and impresses the control from the unit 10 to the motor 8. |
