In a first step, a pulling operation is performed with respect to four tools by retaining, in an immovable state, a leftmost tool from among the four tools lined up on a tool mounting unit by means of a left ATC and by moving, toward the left ATC, a rightmost tool from among the four tools by means of a right ATC. In a second step, a movement of the right ATC is stopped when a torque of a motor for moving the right ATC in a left-right direction reaches a preset set value. The first step includes a choosing step of choosing, for the respective left and right ATCs, whether to perform the pulling operation in a state of being abutted against respective side surfaces of the tools or to perform the pulling operation in a state of being engaged with respective engagement holes of the tools.

Method of arranging divided tool and press brake

In a bending system and a method for using the same, the bending system includes a bending robot provided between a press brake and a predetermined setting area that is arranged in front of the press brake to assist in bending a workpiece. The bending robot includes a robot hand for holding the workpiece on a pallet that is set in the predetermined setting area. An image pickup unit, which picks up an image of the workpiece on the pallet from an oblique upper direction, is provided above and anterior to the predetermined setting area. A first illumination unit, which illuminates an image pickup area of the image pickup unit, is erected on a left front side of the predetermined setting area. A second illumination stand, which illuminates the image pickup area of the image pickup unit, is erected on a right front side of the predetermined setting area.

Bending system and method for using the same

Different divided tools are attached to tool attachment portions using automatic tool changers in proximity to slit tools that have already been attached to tool attachment portions. The attached different divided tools are moved toward the previously attached divided tools using the automatic tool changers, and the different divided tools are caused to abut on the previously attached divided tools. In a case in which a torque of a servomotor for moving the automatic tool changers in a left-right direction has reached a setting value set in advance, the different divided tools are detected to have abutted on the previously attached divided tools, and the moving of the different divided tools is stopped.
