1) Outline of positioning
The machine moves a workpiece from the left table to the right table.
A single solenoid is used to move up and down the workpiece.
2) Operating procedure
c
The machine returns to the zero point by the start
command only at the first time.
d
The move-down solenoid Y0 turns on. When the
lower limit X0 turns on, the clamp solenoid Y1
turns on and the machine clamps a workpiece.
e
After the clamp wait period of time (1.5 seconds),
the move-down solenoid Y0 tur ns off and the
machine moves up.
f
When the upper limit X1 turns on, the machine
moves to the right table.
g
When the machine reaches the right table, the move-down solenoid Y0 turns on. When
the lower limit X0 turns on, the clamp solenoid Y1 turns off and the machine unclamps (=
releases) the workpiece.
h
After the unclamp wait period of time (1.5 seconds), the move-down solenoid Y0 turns off
and the machine moves up.
i
When the upper limit X1 turns on, the machine returns to the left table.
