Checking the Lifter Speed
1. Select [Manual Operation] – [Conveyor Operation] – [Main Lifter Up/Down] to raise and
lower the main lifter. The travel time should be in the following range:
Moving UP 400 – 600 ms
Moving DOWN 700 – 900 ms
Note: If the travel time is not in the range, re-adjust the main lifter speed controllers.
4.7 Adjusting the Main Stopper
Measuring jig: Plate jig (AJPJ-0060)
Main stopper adjustment
1. Select [Maintenance A] – [I/O Check] – and turn Y02A
MainStationStp OFF to lower the main stopper.
2. Lower the lower limit sensor (I/O X01F
MainStStpOffChk) until it turns OFF.
3. Raise the lower limit sensor, and lock the sensor 1mm
above the point it first turns ON.
4. 4.Select [Maintenance A] – [I/O Check], and turn ON
I/O Y02A MainStationStop to raise the main stopper.
5. Raise the upper limit sensor (I/O X01E
MainStStpOnChk) until it turns OFF.
6. Lower the upper limit sensor, and fasten the sensor
1mm below the point the sensor first comes ON.
7. Adjust the position of the main stopper as is shown in the following diagram:

Note: Set the main stopper at a right angle to the fixed rail.
4.8 In-lifter adjustment
1. Select [Maintenance A] – [I/O Check], and turn I/O
Y02D InStLftUpChk ON to raise the in-lifter.
2. Adjust the cylinder stopper bolt so that the clearance
between the in-lifter air cylinder stopper and
underside of the lifter plate becomes 1.0mm.
3. Turn I/O Y02D InStLifterUp OFF to lower the in-lifter.
The top of the lifter plate should now be flush with the
conveyor belt top surface. If not adjust the tilt of the
lifter plate.
4. When step 3 is complete turn I/O Y02D InStLifterUp ON to raise the in-lifter.
5. Now repeat the procedure in step 2, but this time set the clearance to 1.5mm.

6. Turn I/O Y02D InStLifterUp OFF to lower the in-lifter. Ensure that the lifter plate top
surface is approx. 0.5mm below the conveyor belt top surface. Use a ruler to check.
Confirm both the height and tilt.
7. After adjustment is complete, place a board on the in-conveyor and raise the in-lifter.
Check that the board is not jolted up. And also ensure that the reference side/movable-
side up/down speed is balanced. If not, adjust using the cylinder speed controllers.
8. Air Cylinder Upper Limit Sensor
Turn I/O Y02D InStLifterUp ON and raise the in-lifter. Carry
out the upper limit sensor adjustment. (I/O X028
InStLftUpChk) Slowly raise the sensor from the lower
position until the sensor turns ON and keep raising until it
goes OFF. Then, lower the sensor until it comes ON and
fasten the sensor approximately 1mm below the point that it
first comes ON.
Top surface of
the conveyor belt
Ensure that when the plate is lowered, the
plate top surface is approximately 0.5mm
below the conveyor belt top surface.
When the plate is raised, the plate
top surface should be raised
approx. 1mm from the conveyor
belt top surface.
