Abstract: Provided is an angle change device for an automatic conveyor system. The angle change device includes: a slate conveyor having guiding grooves formed to cross the slate conveyor; lift units disposed to vertically cross the slate conveyer to lift a loaded material up from the guiding grooves of the slate conveyor; a forward/backward driving unit including driving sprockets between rails arranged to cross the slate conveyor between the lift units and a driving motor; a rotation guiding shaft pin; and a turntable carrier unit including a moving plate for dynamically approaching to or retreating from the slate conveyor and a rotating plate for repeatedly rotating about the rotation shaft in a clockwise and a counter clockwise at predetermined angle when the rotating guiding shaft pin catches the rotating plate while moving in a forward direction or in a backward direction.
