3.5 Safety Function
3.5.1 Safety Protection
The robot with cut off pneumatic protection device (picture 3-4) can prevent the damages
cause by arm falling when air pressure is not enough.
If the air pressure is not enough, the sensor will output the signal. The robot
’
s arm keeps in
current position or returns to the up limit position, then the pneumatic cut off protection
device locks the piston rod (if the arm out from inner mold, it will keep at current position, if
out from the outside of mold, the arm will back to the up limit position).
When the air pressure is sufficient, the pneumatic cut off protection device will set free and
the robot will work again. In addition, there is a manual ring on the device. When the air
pressure is insufficient and the arm is in locked state, the customer can manually pull the
ring and pull out the piston rod to move it.
