•How to distinguish lifter cylinder boa up front & rear.
Boa up (front) = Cylinder side and joint side arm width the same (10mm).
Boa up (rear) = Cylinder side is 18mm longer than the joint side.
[3-5 ] Table Mechanical Valve Adjustments
Note: The following adjustment should be performed only after the lifter plate height
measurement is completed.
1) High-speed cam adjustment for DOWN motion
1. Lower the lifter plate to a point 7mm below the UP limit.
2. Insert a 3mm spacer beneath the lever which presses the mechanical valve switch, then
press the lever against this spacer and secure the cam, making sure that the cam is
against the lever.
2) High-speed cam adjustment for UP motion
1. Position the lifter plate at its DOWN limit position.
2. Insert a 2.5mm spacer beneath the lever which presses the mechanical valve switch, then
press the lever against this spacer and secure the cam, making sure that the cam is
against the lever. (The lifter plate is probably at its DOWN limit at this time, leaving no
space to insert your hand in order to secure the cam. Therefore, make a mark to show
the cam and shaft positional relationship, then raise the lifter plate to its UP limit
position and secure the cam at the marked position. Because the PCB is subjected to
impacts each time this cam adjustment procedure is performed, be sure to perform it
correctly
the first time.)
Table mechanical valve adjustment
Turn the cam to adjust as shown below.
(Be sure to note the cam
direction)
* Note: Although the loading cycle time measurement procedure is described in section [9-1], the
air valve and mechanical valve adjustments performed as described in sections [4-4] and [4-5]
should be readjusted so that they are as close as possible to the reference cycle time values
shown below.
Reference cycle time values: Loading time (4.11 sec) = unclamping time (0.64 sec) + board
unloading and board loading time (2.26 sec) + clamping time (1.21 sec)

[3-6 ] Fixed Rail Parallelism and Flatness Measurement
1) Parallelism measurement
Measure the parallelism of the conveyor's fixed rail (side face) relative to the X-axis.
2) Flatness measurement
Adjust the secondary rail so that the width between conveyors is 200mm.
With the fixed rail as the zero point, measure (at bottom face of board clamp guide bar) the
difference between the fixed and secondary sides.
[3-7 ] Board Clamp Adjustment
1) DOWN limit adjustment
Verify that the table is at the DOWN position, then turn the DOWN limit adjusting bolt until
the clamper's top face is 0.3 to 0.5mm lower than the conveyor belt's top face.
2) UP limit adjustment
Loosen the UP limit adjusting bolt, then raise the clamper by hand until the adjusting jig is
pinned between the conveyor bracket's top face and the UP limit adjusting bolt (this height is
53.2 ^ 0.05). With the adjusting jig pinned in this manner, turn the UP limit adjusting bolt
until there is no jig looseness in the up/down directions, but not so tightly that the jig cannot
be extracted.
3) Post-adjustment check
* Use an I/O command to raise the table, verifying that the clamper operates smoothly.
* Lower the table and introduce a board into the system, verifying that the board passes
through the system in a smooth manner.

[3-8 ] Table UP Limit and DOWN Limit Sensor Adjustments
1) Turn the "Y023 CNVYR BRD CLMP" I/O command on to raise the table at the module in
question. Adjust the UP limit sensor dog so that the sensor switches on when a 4mm board
is clamped, and off when a 4.8mm board is clamped.
2) Turn the "Y024 CNVYR BRD UNCLMP" I/O command on to lower the table. Starting from
the position where the sensor is on, raise the dog until the sensor switches off. Next, lower
the dog to find the point where the sensor switches on again. Secure the dog 1mm below
that point.
3) Turn the I/O commands on and off to raise and lower the table, verifying that there is no
sensor hunting, etc.
[3-9 ] Board Stopper Sensor and Stopper Position Adjustments
1) Turn the "Y022 CVR BD STPR IN" I/O command off to lower the board stopper. Beginning
from the position where the DOWN limit sensor is on, gradually lower the sensor to find the
point where it switches off. Secure the sensor 1mm above this point.
2) Turn the "Y022 CVR BD STPR IN" I/O command on to raise the board stopper. Beginning
from the position where the UP limit sensor is on, gradually raise the sensor to find the
point where it switches off. Secure the sensor 1mm below this point.
3) Adjust the stopper position as shown below.
* Use the I/O command to raise the board stopper, and check the adjustments at the UP
limit position.
