As the electric winch 230 is driven, the order profile 120 rises and is partially stored by being wound around the winding roll 210.

Meanwhile, since the order profile 120 is coupled in an inserted state by the first link 130a and the second link 130b, the coupling may be released when the order profile 120 is wound around the winding roll 210 and reversed direction. Therefore, as explained in FIG. 3, the rotation of the profile 120 disposed at the top must be controlled only at an angle perpendicular to the upper surface of the winding roll.

For this purpose, the driving unit 200 is provided with a protruding anti-separation rib 220 provided on the circumferential surface of the winding roll 210. The anti-separation rib 220 is provided only with a length corresponding to 1/4 of the circumferential surface. A plurality of rollers 221 are disposed on the outside to ensure smooth movement of the wire W.

The anti-removal rib 220 is provided with a receiving plate 222 at an end facing the profile 120. When the order profile 120 of the winding roll 210 is lowered, the anti-separation rib 220 is located in the first quadrant as compared to an xy-axis graph, as shown in FIG. 1 or FIG. 2 . In this state, when the wire (W) is wound by driving the electric winch (230), the winding roll (210) does not rotate until the uppermost order profile (120) touches the receiving plate (222) and the wire (W) It is guided and wound on the roller 221.

When the uppermost order profile 120 reaches the receiving plate 222, the uppermost order profile 120 pushes the receiving plate 222 and the winding roll 210 rotates to accommodate the order profile 120. Since the electric winch 230 winds the wire (W) according to the protruding height of the removal prevention rib 220, the winding roll 210 rotates only by 90 degrees.
