摘要： A zero point adjusting method and apparatus for a pressure detector of an injection molding machine, capable of carrying out a zero point adjustment of the pressure detector when external loads acting on the pressure detector are completely removed without disassembling an injection mechanism. An advance limit position Qf and a retreat limit position Qb of a screw are detected by driving the screw with a low output to determine an intermediate position Pm. By moving the screw to the intermediate position Pm, a resin reaction force acting directly on the screw is removed. Reciprocating motion in which an amplitude decreases gradually is imparted to the screw, thereby causing a backlash, having equal plays in the advance and retreat directions, between a ball nut and a ball screw. Then, the zero point adjustment of the pressure detector is made.

A mother mold of a complementary die in the core change type dies is constituted by a main body and an intermediate plate which is disposed behind the main body and to be movable in both the forward and backward directions. A core fixing and releasing mechanism is provided on the intermediate plate. Furthermore, there is provided a push-out device disposed in a clearance formed between the main body and the intermediate plate when the intermediate plate is shifted rearward. The push-out device has its one surface abutting on a front surface of a core and its another surface abutting on a rear surface of the main body. The push-out device is attached to a distal end of an arm of a robot, combined with a molding machine, so that the push-out device is slidable in both the forward and backward directions and is urged rearward, if necessary.

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.
