摘要： PURPOSE:To permit a robot hand to attract plate members without making a movement for avoiding positioning plates, by causing the upper surface of uppermost plate members to project from the upper end of the positioning plates at all times. CONSTITUTION:When plate members W1-W4 are set after their stacking direction has been determined by positioning plates 2A-2D, a robot hand 100 moves to a position for attracting the plate members. As soon as the respective uppermost plate members are attracted by attracting magnets 101A-101D, a limit switch 5 contacts the robot hand 100 for operation. The operation of the limit switch 5 causes a hydraulic cylinder 3 to contract so that the respective positioning plates 2A-2D lowers all together. When the robot hand attracting the plate members is apart from them, the limit switch 5 is not energized and the contracting operation of the hydraulic cylinder stops, whereby the respective positioning plates 2A-2D are held at the position lowered by the thickness of a plate member.

摘要： PURPOSE:To aim at the promotion of high accuracy for positioning, by depressing a second movable body after engaging a lot of plate members aligned in a feeder mechanism by a positioning guide, with a first movable body through an extruding block, and making the second movable body go up to a position where a robot hand grips in the engaged state. CONSTITUTION:When a lot of plate members W are set to a feeder mechanism 1, side surfaces are aligned by a guide plate 3 and upper and lower surfaces by a guide rail 4, respectively, and a plate member W1 at the endmost is engaged with an engaging surface 17 of a first movable body 13 of a pushing mechanism 2 by an extruding block 5. Next, when a robot hand 100 depresses a head part 14a of a second movable body 14, the first movable body 13 goes up whereby the member W1 is pushed up to a space between fixed and movable claws 101 and 102 of the hand 100. When the movable claw 102 grips the member W1 with help of an actuator 103 and shifts to an assembling part, the movable body 14 moves upward by dint of a spring 19 while the movable body 13 returns whereby the next member W is engaged. Accordingly, the plate member can be positioned in a highly accurate manner without installing the actuator or the like in a device itself.
