Next, when a pallet loaded with workpieces was sent to explain the Ilu+ work, the hand was first placed near the workpiece by the robot, and then the rod was placed at the air cylinder station. By descending, the magnet (1) comes into contact with the workpiece and attracts the workpiece. After adsorbing the workpiece, the rod 1 is raised using the air cylinder (2), and the grinding stone (1) is retreated to the center of the claw (3). In this state, there are considerable variations in the position and posture of the workpiece relative to the hand. Figure 3 shows the process of moving the workpiece from this state to the correct position without changing the grip using the hand according to the present invention. Indicates medium/b.

After the positioning is completed in this way, the hand transports the workpiece onto the supply position. From this state, the grinding stone (1) further retreats to 1〆f until it no longer applies magnetic force to the workpiece (c), and when the claw (3) opens, the workpiece is completely supplied to the required location by VC.

In the above embodiment, the driving source is an air cylinder or a rotary actuator, but it may be replaced with another driving W source, the timing belt of the transmission means may also be formed using another method, or the opening and closing of the pawl may be changed.・Although this is achieved by using a pick and pinion, it is obvious that it can also be achieved by other means.

As described above, according to the present invention, the magnet for attracting the workpiece can be supported with respect to the workpiece in a forward and backward manner, and the workpiece can also be moved forward and backward (the main claw rotates around the magnet and is attached to the grinding stone). Since it is not provided so that it can move forward and backward, it can be accurately supplied to the required location without having to place the supplied workpiece on the way and change its grip, and there is no need for time to change the grip. This has the effect of eliminating the need for a workpiece position determining device used for hawks.
