smart moving rack having prevention device to avoid fallen object or collision and its using method

摘要

The present invention relates to a smart moving rack (10) for performing warehousing or unstoring of freight within a freight center, and having a device for preventing a fallen object or a collision with a front object occurring during movement of the moving rack (10). The smart moving rack comprises: a base part (100) provided on one side of the moving rack (10) moving the freight, and providing a predetermined space; a bumper part (200) provided on one side of the moving rack (10), and having a damper (210) absorbing an impact applied from an object colliding on a travel path, and a sensor sensing a location of the object; and a control unit determining and controlling whether to perform traveling according to information input from the sensor. The smart moving rack prevents a collision with the object sensed on the path and senses the fall of loaded freight during traveling of the moving rack (10) to determine whether to perform traveling. Further, the present invention relates to a control method for the smart moving rack (10) having a device for preventing a fallen object or a forward collision comprising the steps of: supplying power and preparing traveling; performing the traveling through the input information; operating an ultrasonic sensor (222) to sense an obstacle in the travel path within a predetermined distance; sensing whether a falling object occurs; and terminating the traveling.
