2. Transfer mechanism
The upper left position is regarded as the zero point. The machine transfers a workpiece from the left to the
right in the order "moving down
→
clamping
→
moving up
→
rightward travel
→
moving down
→
unclamping
→
moving up
→
leftward travel."
Double-solenoid type solenoid valves (with two inputs for driving and non-driving) are adopted for moving
down, moving up, leftward travel and rightward travel. Single type solenoid valves (which operate only while
the power is ON) are adopted for clamping.
