The present invention relates to an automatic fork control apparatus of a forklift, automatically moving a fork of a forklift to a task position of each pallet when loading/unloading pallets on a shelf frame made of multiple shelves with the forklift, and a control method thereof. The automatic fork control apparatus of a forklift according to the present invention is an automatic fork control apparatus of a forklift loading/unloading pallets by moving a fork of the forklift up and down, and back and forth through controlling a hydraulic apparatus. The automatic fork control apparatus of a forklift according to the present invention comprises a marker unit installed on a shelf frame having multiple shelves; a detection unit installed in the forklift and detecting the marker unit; a storage storing each distance from the marker unit to the task position of pallets on each shelf; a shelf number setting unit setting the number of shelves to perform the loading/unloading task of pallets; a moving distance calculating unit calculating the moving distance in ascending/descending the fork; and a control unit controlling the hydraulic apparatus to move the fork according to the number of shelves set in the shelf number setting unit when the detection unit detects the marker unit, and controlling the hydraulic apparatus to stop the movement of the fork when the moving distance of the fork calculated in the moving distance calculating unit reaches the pallet task position on the set number of shelves from the marker unit stored in the storage. [Reference numerals] (110) Marker unit; (120) Detection unit; (130) Shelf number setting unit; (140) Storage; (150) Moving distance calculation unit; (160) Control unit; (170) Mode input unit; (180) Display unit; (20) Hydraulic apparatus; (21) Motor; (30) Fork |
