ABSTRACT:
There is provided a three-dimensional laser beam machining apparatus for a long workpiece, which includes an automatic loading device for a large variety of materials that feeds materials to a three-dimensional laser beam machine. The automatic loading device100for a large variety of materials has a bundle type material loading device120. A bundle type material W1is a round pipe or a polygonal pipe, and the posture thereof around the axis line is aligned automatically when the material is conveyed by a roller conveyor140. The front material stopped by a stopper150is sent out to an inclined conveyor180over the stopper150by means of a swing arm170. The bundle type material as well as a versatile type material, the posture of which around the axis line is not aligned automatically, are set on a receiving member210of a common conveyor200and sent to the three-dimensional laser beam machine by the operator.
