1. A method of controlling a garment folding machine having a plurality of folding layers that performs a function of folding a garment using at least one conveyor or a function of conveying the garment, the method comprising:
a folding-layer-operating/garment-lumping-determining step of operating a conveyor motor configured to operate at least one conveyor to fold or convey the garment, detecting whether the garment has reached a target position after the operation of the conveyor motor is initiated, measuring a current value of the conveyor motor based on a determination that the garment has not reached the target position, calculating a delay time after the operation of the conveyor motor is initiated, and determining whether garment lumping has occurred based on the motor current value or the delay time,
wherein the garment lumping determining step determines whether the garment lumping has occurred by determining (i) whether the delay time exceeds a preset predetermined critical delay time or (ii) which the motor current value exceeds a preset predetermined critical current value, and
wherein the garment lumping determining step determines whether the garment lumping has occurred in a first folding layer among the plurality of folding layers.
