Chapter 5 Loader and Conveyor Adjustment
5.1 Air Leakage Check
1. Check the cylinder tubing and operation by activating the loader solenoid valves manually.
2. Ensure all air tubing is tight and free of air leaks.
5.2 Carrier Claw and Pin Check
1. Ensure all carrier claws are straight and aligned.
2. Ensure the pin is centered above the cutout in the claw.
3. The pin should be positioned approximately 0.2mm above the claw cutout.
4. Ensure the pins move smoothly in and out.
5. If it is necessary to remove the carrier assembly, remove only the two screws at each
arrow location.

5.3 Carrier Unit Stroke Check
1. Lock the OUT carrier at the forward end and check the stroke as indicated in Fig. 4
2. Adjust the out conveyor forward end shock absorber on the rod-less cylinder so the carrier
position is 556mm from the cut out in the right cam box pillar.
3. Lock both carriers at their forward ends and set a gap of 21.5mm between the two carriers,
by moving the in carrier shock absorber.
4. IMPORTANT: ensure there is a 21.5mm gap between the two carriers. Otherwise,
interference with the main table will result in damage to the machine.

5.4 Rod-less Cylinder Stroke Check
1. Check the stroke of the IN and OUT carrier rod-less cylinders as indicated in the following
table and Fig. 6.
2. Set the stroke by adjusting the backward end shock absorber on the rod-less cylinder.
CP-643E IN carrier (Upper side) 629.0 mm
OUT carrier (Lower side) 613.5 mm
Note: Check the stroke after locking the IN & OUT carrier at their forward ends.
5.5 Conveyor Assembly Accuracy Check
1. Confirm that the PCB guide plates (2.5mm) are aligned with the upper surface of the
conveyors.
2. Confirm that the conveyor width change unit and stopper unit move smoothly by
hand.
3. Check whether the lifter plate is bent or scratched.
4. Check the maximum, minimum width and the entrance/exit of the IN & OUT conveyor.
5. The difference between the IN and OUT conveyors must be within 0.2mm. Change the
connecting chain if the value is out of tolerance.
