PURPOSE: A pack widening robot device is provided to easily put contents inside a pack open and to prevent contents from falling outside with an inlet closed in the middle of putting contents inside the pack. CONSTITUTION: A bag supply unit that receives a bag withdrawal signals from a control unit operates a belt drive part for withdrawing by piece. The withdrawn bag is carried into a center of a fixing frame and a movable frame(10) of a base plate(2) through a withdrawal guide. The control unit confirms the movable frame(10) butted with the fixing frame via a sensor(60) and sends an operational signal of 1,2,3 pincette units(4,5,8). According to the operational signals, 1,2,3 motors(24,38) rotate for rotating 1,2,3 worm gears(18,26,36) and 1,2,3 worm wheels(20,28) rotate together. Ends of 1,2 finger members(22,30) rotate clockwise and are butted to inner sides of the fixing frame(7) through 2,3 recessed grooves(31) of the movable frame(10) to fix both sides of rear face of a 3 groove(53). Furthermore, a 4 motor(43) reversely rotates for rotating a pinion(42) and a rack(44) moves rightward for separating the movable frame(10) from the fixing frame(7).
