When transported within the working range and stopped, step (21)
Then, the down command is issued to (1a). At this time, the state of each part of the hand (2) is as shown in FIG. 2, and the gripping pawls (11) are open to each other. When the arm (1a) descends, the arm (1a) stops at step (22). Then, in step (23), a gripping command is issued, the driving machine (7) operates, the actuating rod (7a) moves forward, and the gripping pawls (11) move to each other via the lever (8) and the spur gear (10). Rotate in the direction of approaching, the third
As shown in the figure, the bent portion of the tip engages with the grip hole (5a) of the work (5), and the grip is completed in step (24).
Next, in step (25), a downward command is issued to the pusher (13), the driving machine (12) operates, the actuation rod (12a) descends,
The pusher (13) descends and presses the upper edge of the work (5) as shown in FIG. 5 to prevent it from rising. Further, the work piece (5) is formed by the recess (13a) of the presser (13).
Mutual movement is prevented. This completes the work suppression in step (26). Then, in step (27), a transfer command is issued, and the arm (1a) moves up, turns, and descends, places the work (5) on the pallet (4), and operates and reverses the order described above. The child (13) is pressed and the gripping pawl (11) is opened, and the stacking of the works (5) is completed.
