Abstract: A device capable of determining whether or not to clean a work area of a machine tool with higher accuracy. The device includes an imaging device configured to capture first image data of the work area before machining, and configured to capture second image data of the work area after machining, an image data generation section configured to generate third image data indicating a degree of change between brightness of a pixel of the first image data and brightness of a pixel of the second image data, and a determination section configured to determine whether or not to clean the work area based on a histogram indicating a relationship between the brightness of the pixel of the third image data and the number of pixels of the third image data.

Abstract: A cleaning system capable of improving efficiency of a cleaning operation onto a work area of a machine tool. The cleaning system includes a cleaning nozzle attached to and detached from an attachment device provided in the machine tool, and configured to inject fluid; a robot configured to grip the cleaning nozzle; and a cleaning execution section configured to execute a detaching operation to operate the robot so as to grip the cleaning nozzle attached to the attachment device and detach the cleaning nozzle from the attachment device, and a cleaning operation to move the cleaning nozzle with respect to the work area by the robot, and inject the fluid from the cleaning nozzle to clean the work area.

Abstract: A tool information read/write device capable of being used in an automatic tool changer to which a conventional tool information read/write device cannot be applied, and a machine tool having the tool information read/write device. The read/write device has an arm section attached to a turret support part; a base section attached to the arm section; a slide section arranged on the base section so as to be linearly moved; a read/write head section attached to the slide section and configured to read/write information to a data carrier of a tool held by the turret; a drive section which drives the slide section so that the slide section reciprocates between a read/write position and an evacuation position; and a control section which controls the drive section in conjunction with a motion of the automatic tool changer.

Abstract: An industrial robot is provided with a cable laying arm (20) extended on one side of a robot trunk (12) so as to form a dual arm structure in combination with a structural arm (18) extended on the other side of the robot trunk (12). A bundle (58) of cables capable of being detachably connected to the robot unit is extended in the cable housing element (50) of the cable laying arm (20) so that the cables including power supply cables and signal transmission cables are not exposed to the outside. The whole cable housing element (50) can be readily removed from the robot trunk (12) together with the bundle (58) of cables, in case any one of the cables is disconnected, to permit repair of the disconnected cable.

Abstract: An articulated industrial robot comprises a robot body (10), a robot upper arm (20) pivotally supported in a joint provided on the upper end (16) of the robot body (10) for a swing motion about a horizontal W-axis, and a robot forearm (30) pivotally supported in a joint provided on the extremity (24) of the robot upper arm (20) for an up-down turning motion about a horizontal U-axis. The robot upper arm (20) has an offset arm structure extending between the horizontal W-axis of the joint on the upper end (16) of the robot body (10) and the horizontal U-axis of the joint on the extremity (24) of the robot upper arm (20) with its back side (26) extending along the straight line connecting the respective centers of the horizontal W-axis and U-axis. Electric cables (40) and the like are extended along the back side (26) of the robot upper arm (20).

Abstract: An industrial robot for use in TIG arc welding or the like includes plastic covers for motors or the like. The plastic covers having an electrically conductive coating, and thus have an electrically conductive property, and are connected to a robot body, to thereby obtain a shielding effect similar to that of iron plate covers or the like.
