AUTOMATED GUIDED VEHICLE AND METHOD USING THE SAME

摘要

According to the present invention, an unmanned transfer device comprises: a carriage (100) and a rail (200) on which the carriage (100) is mounted to be movable. The carriage (100) comprises: a transfer plate (110); mounting plates (120, 130) arranged in a front side or a rear side of an undersurface of the transfer plate (110); main rollers (140) formed on an undersurface of the mounting plates (120, 130); a motor (180) to supply power to the main rollers (140); a detection sensor (190) to irradiate light to the rail (200); and a control part (195) connected to the motor (180) and the detection sensor (190). One or more operation sections (A) arranged on a linear path and one or more rotation sections (B) arranged on a curved path are set on the rail (200). The rail (200) comprises: a plurality of rail grooves (230) vertically formed on a side surface of the rail (200); and a plurality of detection blocks (240) respectively arranged on the sections (A, B) while being arranged on the plurality of rail grooves (230). The plurality of detection blocks (240) contain a first detection block (241) vertically crossing the plurality of rail grooves (230); and a second detection block (245) arranged behind the first detection block (241) while being arranged on one among the plurality of rail grooves (230). The control part (195) controls a moving speed of the carriage (100) according to whether or not the detection sensor (190) recognizes a signal from the plurality of detection blocks (240).
