<p>A blade rotating apparatus is provided to shorten the interval of operation time of a long robot apparatus by rotating a blade with respect to the lengthwise central axis of the blade. A pneumatic cylinder(210) generates rotation power by using compressed air. A gear box(230) transfers the rotation power of the pneumatic cylinder to a blade(130), connected to the pneumatic cylinder by a connection axis. The blade mechanically connected to the gear box is rotated with respect to the lengthwise central axis of the blade by using the rotation power of the pneumatic cylinder. A magnetic limit sensor checks the operation state or position of the pneumatic cylinder to precisely control the rotation of the blade.</p> |
