Therefore, when the rotary actuator 57 of the device 8 is activated and the rotating shaft 58 is rotated by 180 degrees, the lower frame plate 75 is also rotated by 180 degrees. By the way, the upper surface 8 of the lower frame board 75
o was initially in a horizontal state, but the rotating shaft 58 tilted at an angle of 10 degrees rotates 180 degrees, and the lower surface of the lower frame plate 75 connected perpendicularly to this rotating shaft 58 also rotates at an angle of 1°. , the upper surface 80 of the lower frame plate 75 inverted from the horizontal state is inclined at an angle of 20 degrees with respect to the horizontal plane. The one-dot chain line shown in FIG.
This shows the inverted state of . In this state, the lifting cylinder 76 is operated to raise the tool gripping part 61 to an appropriate height, and the cylinder 70 is then operated to advance the grip claws 62 and 62, and the cylinder 67 is operated to raise the fitting member. 64 from between both grip claws 6262. The gripping claws 62.62 that have advanced will eventually collide with the tool 6o, but the gripping claws 62.62 will further advance (
If you do it with arrow A), the grip claw 6 hits the tool 60.
