    摘要: In a horizontal revolute robot, an upper end of a ball screw (21) of a direct-acting actuator (100) is rotatably supported by a top plate of a column (10), and the lower end thereof is coupled to a drive unit (40) disposed on a base plate of the column. A first link (220) is pivotally coupled to a coupling member (210) of a manipulator (200) fixed to a slider (30) of the actuator, and a second link (240) is pivotally coupled to the first link. The ball screw is rotated by the drive unit to move the manipulator along the ball screw in unison with the slider, and servomotors (230, 250) of the manipulator are driven to turn both the links within a horizontal plane, so that a wrist portion of the robot is positioned in a robot installation space for robot operation. Since no base is required to turnably support the actuator, the robot is small-sized, light in weight, and low-priced. Since the lower movement limit position of the manipulator is low, the range of action of the robot is wide.

    摘要: A laser-beam mis-emission preventing method capable of improving safety of a laser robot. Upon supply of power to the laser robot, a processor of a robot control unit (10) compares a predetermined value with an angle (.delta.) formed between a horizontal plane (XY plane) and an axis (8a) of a laser nozzle (8) and computed based on joint angles (W, U, r, .beta.) (S1-S3). When the laser nozzle angle (.delta.) is less than the predetermined value, an interlock signal delivered to the laser oscillator (30) is set to turn off the power of the laser oscillator, thereby bringing the laser oscillator into a condition incapable of laser oscillation (S5). This prevents mis-emission of the laser beam which occurs due to deficiency of a robot operating program, erroneous manual operation, etc., and which can damage the human body or peripheral devices.

    摘要: A joint structure for an industrial robot is provided with a gear transmission mechanism to drive movable robot element, such as a swivel body (14), of an industrial robot. The joint structure comprises a driven gear (26) connected to the movable robot element, two drive pinions (28, 30) in mesh with the driven gear (26), respectively, at different positions on the driven gear (26), a belt transmission mechanism (28a, 30a, 32) operatively connecting the two drive pinions (28, 20), a tensioner (36) for adjusting the tension in the power transmission belt (32) of the belt transmission mechanism (28a, 30a, 32), and a rotative drive source (34) connected to one (28) of the two drive pinions (28, 30). The position of the tensioner (36) is adjusted to adjust the tension in the power transmission belt (32), to thereby eliminate backlash between the respective meshing teeth of the two drive pinions (28, 30) and the driven gear (26), by pressing the respective teeth of the drive pinions (28, 30) against the corresponding teeth of the driven gear (26), respectively, in opposite directions.

The lower arm (13) has provided thereon a forearm (14) pivotably about a second horizontal axis (C2). The forearm (14) is rotationally driven by a drive such as a motor (16). The robot body (12) has provided thereon a rotating disk (17) interlocked with the pivoting of the forearm (14) about the second axis (C2) and rotatable about the first axis (C1). Also the rotating disk (17) has secured thereon a first wheel (18) and coaxial therewith, the diameter of which is smaller than that of the disk. There is further provided a tension spring assembly (19) having one end thereof connected to the robot body (12) and which has rotatably mounted at the other end thereof a second wheel (21) having nearly the same diameter as that of the first wheel. Also provided is a chain (22) having one end thereof connected to the rotating disk (17) and the other end engaged on the first wheel (18). This chain (22) is engaged on the outer circumference of the second wheel (21) while pulling the tension spring assembly (19). The one end of the chain (22) is so disposed on the rotating disk (17) that when the upper end of the forearm (14) is directed normally downward, the chain portion (22b) between the rotating disk (17) and the second wheel (21) is substantially parallel to the chain portion (22c) between the first and second wheels (18) and (21).

    摘要: A workpiece feeder for successively feeding workpieces to a predetermined workpiece gripping station of the robot's hand. The workpiece feeder includes a conveyor having a plurality of interspaced pallets traveling on a table. Each pallet comprises a lower plate having a central opening and an upper plate which is detachably mounted on the lower plate. The workpiece feeder is provided with a lifting means having a vertically movable platform which ascends through the central opening in the lower plate to lift the upper plate away from the lower plate, thereby elevating the workpiece on the pallet up to the level of the gripping position of the robot's hand. The workpiece feeder further comprises a stop mechanism for limiting the topmost position of the platform. The workpiece feeder according to the invention is particularly suitable for use with an industrial robot of the simplified type in which the upright stand enabling the robot's hand to perform vertical translational movement is omitted.
