1. An article withdrawing system for withdrawing articles held in a packing box, an upper surface of which is opened, the article withdrawing system comprising:
a first stage configured to reverse a packing box so as to hold the packing box carried with an upper surface opened and to enable the articles held in the packing box to fall down; and
a second stage configured to support and hold the articles falling down from the first stage,
wherein the first stage comprises a support unit configured to support the packing box and move the packing box upward or downward, a box holding frame on which the support unit is mounted, a linear movement frame to which the box holding frame is rotatably coupled, a main frame located and supported on a ground, with the linear movement frame being coupled to and supported on the main frame so as to be linearly moved, and a first rotation driving means disposed in the linear movement frames frame and for rotatably driving the box holding frame,
wherein the second stage comprises an article holding frame having a holding surface of a shape complementary to a shape of the article so as to hold the articles falling down from the first stage, a fixed frame located and supported on the ground, with the article holding frame being rotatably coupled to the fixed frame, and a second rotation driving means for rotating the article holding frame relative to the fixed frame,
wherein when the packing box in which the articles are held is rested on the support unit of the first stage, the article holding frame of the second stage is rotated relative to the fixed frame such that the holding surface faces downward,
wherein after the linear movement frame of the first stage is linearly moved along the main frame such that the opened upper surface of the packing box faces the holding surface of the article holding frame of the second stage, the packing box is moved upward by the support unit such that the upper surface of the packing box approximates to or abuts the holding surface, and
wherein the box holding frame of the first stage and the article holding frame of the second stage are respectively rotated relative to the linear movement frame and the main frame in a state in which the upper surface of the packing box approximates to or abuts the holding surface, so that a position of the packing box is reversed and the articles held in the packing box fall down and are held in the article holding frame.
