摘要:
A production system in which a human and a robot may simultaneously perform a cooperative task in the same area while ensuring human's safety. A robot is positioned at one side of a working table, and an operator is positioned at the other side of the working table. The reachable area of the operator is limited by the working table. An area of the working table is divided into an area where only the operator may perform a task, an area where only the robot may perform a task, and an area where both the operator and the robot may enter. In a cooperation mode, the maximum movement speed of a component of the robot is limited lower than when the component of the robot is outside the cooperative task area, and, the motion of the robot is limited so that the robot does not enter a robot entry-prohibited area.
摘要:
A human-robot interactive system in which a robot and a human share an area for performing interactive work, the human-robot interactive system including a force sensor which is set at an end effector attached to a front end of the robot or which is set at the robot and, when a detected value of the force sensor exceeds a predetermined value, is configured to stop the robot or controlling operation of the robot so that a detected value of the force sensor becomes smaller, the system further including a limiter which limits a work area of said human so as to prevent contact by the human with the first robot portion of the robot that is positioned further from the human than a set position of the force sensor during operation even when the robot approaches the human.
摘要:
A double-hand unit adapted to be secured to the wrist part of an industrial robot and to be used for gripping shaft works or the like is disclosed. The double-hand unit comprises two hand units (2, 3) comprising at least two pairs of fingers (2-1, 2-2 and 3-1, 3-2), respectively, and being disposed in a back-to-back relationship with the respective opening sides of the fingers directed in opposite directions with each other. The driving mechanisms for operating the associated fingers of the hand units (2, 3) are disposed one over the other along a plane including the fingers.
摘要:
A hand (34) of an industrial robot for gripping a workpiece (14) and the like comprising: a hand base plate member (36) connected to a wrist portion (32); a plurality of pairs of opening and closing gripping fingers (38a and 38b, 38d) arranged on the palm face (36a) of the hand base plate member (36), and; an actuator (48 or 48') being arranged for each pair of the opening and closing fingers (38a and 38b, 38c and 38d) to actuate the fingers. The hand (34) is capable of securely and stably holding a workpiece having a heavy weight and/or an angular shape, or other complicated shape.
摘要:
A device for operating a hand of an industrial robot is so constructed that fluid pressure cylinders (43, 44) are provided as a driving mechanism of the hand (4) of the industrial robot, branch passages including a pressure-reducing valve (47) are provided in a fluid supply passage to the fluid pressure cylinders (43, 44), the supply of fluid is switched by solenoid valves (SV.sub.2, SV.sub.3, SV.sub.4), and the switching of the solenoid valves (SV.sub.2, SV.sub.3, SV.sub.4) is carried out in accordance with the selected grasping force which has been selected in the teaching mode of the industrial robot, whereby the grasping force of the hand can be controlled stepwisely.
摘要:
A double hand applicable to an industrial robot comprises two hand units (2, 3) comprising at least two pairs, one each, of fingers (2-1 and 2-2, 3-1 and 3-2) and plate members (2-3, 3-3) of a pressing unit (4) disposed in parallel along the center axis of the fingers. The hand units (2, 3) are connected through a pressing mechanism (4) to constitute a double hand in a manner that the respective gripping center axis of the two hand units are in alignment, the respective plate members (2-3, 3-3) of the pressing unit are disposed opposite to each other and the opening sides of the respective pairs of fingers of the two hand units are directed in opposite directions to each other. An opening (6) for allowing a workpiece to penetrate through the plate members is provided for each of the plate members (2-3, 3-3) of the pressing unit attached to the hand units (2, 3 ) respectively coaxially with the gripping center axis so that both hand units (2, 3) are allowed to move freely relative to the workpiece gripped by the hand units (2, 3) along the gripping center axis.
摘要:
A robot hand of an industrial robot used as a manipulating device of a bar-like workpiece having a pair of gripping members attached to a base member and arranged so as to be slid toward and away from one another so that an appropriate distance between the pair of gripping members is established depending on the difference of lengths of workpieces to be gripped by the gripping members of the robot hand.
摘要:
A hand of a robot is moved from an instant position P.sub.1 to a first command position P.sub.2 to grip one of the workpieces W.sub.1, W.sub.2, W.sub.3 placed at the first command position and conveys the same to a second command position P.sub.3. As a sensor is contacted by the workpiece when the hand takes an intermediate position Px, on its way from the instant position P.sub.1 to the first command position P.sub.2, the robot control system decelerates the hand without delay or after a travel of the hand over a predetermined distance and, after travel of the hand over a predetermined deceleration distance, stops the hand. The hand is then moved from the stopping position to the second command position P.sub.3 neglecting the remaining stroke or movement between the stopping position and the first command position.
摘要:
An industrial robot with a safeguard mechanism for mechanically preventing occurence of any uncontrolled movement of a movable part of the industrial robot, the safeguard mechanism having mechanical engagement means which provides a disengageable mechanical lock between the movable part of the industrial robot and the stationary part of the industrial robot or another stationary member different from the industrial robot.
