Three-dimensional laser beam machining apparatus for long workpiece with bundle type material loading device and conveyors

摘要

There is provided a three-dimensional laser beam machining apparatus for a long workpiece (W 1 ), which includes an automatic loading device (100) for a large variety of materials that feeds materials to a three-dimensional laser beam machine. The automatic loading device (100) for a large variety of materials has a bundle type material loading device (120). A bundle type material (W 1 ) is 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 conveyor (140). The front material stopped by a stopper (150) is sent out to an inclined conveyor (180) over the stopper (150) by means of a swing arm (170). The bundle type material (W 1 ) as well as a versatile type material, the posture of which around the axis line is not aligned automatically, are set on a receiving member (210) of a common conveyor (200) and sent to the three-dimensional laser beam machine by the operator.
