Fireproof shutter and transport apparatus including the same

A fireproof shutter comprising:

• a frame having an opening through which a transport rail for movement of a transport vehicle passes, the opening being divided into an upper opening and a lower opening based on the transport rail;
• an upper door mounted on the frame and configured to open and close the upper opening;
• a lower door mounted on the frame and configured to open and close the lower opening;
• and
• a first sensor and a second sensor configured to detect the transport vehicle positioned on the transport rail before the operations of the upper door and the lower door,
• wherein the first sensor and the second sensor are optical sensors configured to detect the transport vehicle positioned on the transport rail prior to activation of the first drive unit and the second drive unit, the first sensor being disposed on a front surface of the frame and the second sensor on a rear surface of the frame,
• wherein a first expandable member is disposed between a lower surface of the upper door and an upper surface of the lower door in a state in which the upper door and the lower door are closed,
• wherein a second expandable member is disposed between the upper door and the frame and between the lower door and the frame in a state in which the upper door and the lower door are closed,
• wherein the second expandable member is attached to the front surface of the frame and surrounds the opening along a perimeter,
• wherein the upper door and the lower door constitute a complementary vertical and horizontal directional movement door assembly in which a first drive unit is provided for moving the upper door in a linear vertical direction between an upper open position and an upper closed position, and a second drive unit is provided for moving the lower door from a horizontal direction to a vertical direction by rotating the lower door about a first end portion adjacent to the frame, the first end portion being vertically moved by the second drive unit during the rotation, and a second end portion of the lower door is horizontally guided toward the frame between a lower open position and a lower closed position.
