  • Patent number: 12094094
    Abstract: A camera is located at a position deviated from directly above a center of a placement location of a workpiece. When a photographed image is generated by photographing, with the camera, the placement location at which the workpiece is placed, an image processing device specifies, by using a preliminarily determined conversion parameter, to which pixels in the photographed image two-dimensional coordinates within a photographed three-dimensional space correspond, aligns the specified pixels corresponding to the respective coordinates in a two-dimensional manner, and generates a corrected photographed image in which a trapezoidal distortion in the photographed image is corrected. A robot control device detects a position of the workpiece at the placement location based on the corrected photographed image, and controls a workpiece retention robot so as to retain the workpiece and transport the workpiece to a processing machine.

  • Patent number: 12059750
    Abstract: An NC device controls a processing machine body so as to form an opening by cutting the periphery of an opening forming area in a material. In a case where a skid interferes with the opening forming area and the interfering skid is positioned within a margin from a first gravity center of the opening forming area in an alignment direction of the skid, the NC device controls the processing machine body so as to cut the opening forming area with a dividing line set at a position that is apart by a predetermined distance from the skid in the alignment direction of the skid. The predetermined distance is a distance in which the material is not welded to the skid, and is a distance in which a second gravity center of a scrap interfering with the skid is positioned at a distance longer than the margin from the skid.
