via inching to the Original_Position_TZ position.

4) With the tray holder in the clamped status, move the TY-axis to the forward limit.

5) Since a gap can be created between the discharged tray holder plate and the MTU71E,

loosen and remove both of the stoppers that were temporarily adjusted earlier.

6) Loosen the cam jaw mount on the bottom of the shuttle jaw mechanism and retract the TY-

axis again via inching. At this point, stop the TZ-axis in a position where the end of the LM

guide rail on the returned tray holder plate skims the guide on the safety door, and where

there is no space between the curved portion of the cam jaw and the cam rollers (since the

cam jaw remains loosened at this time, the position on the LM guide side should be given

precedence).

7) In this position, adjust the position of the loosened cam jaw so that the curved surface on

both the left and right side of the cam jaw catches the cam rollers.

8) From the position at which the above conditions are satisfied, retract the TY-axis another 10

pulses. This becomes Original_Position_TY. Use the following command operation on the

operation panel to enter the value automatically: [PROPER], [DEVICE], [ORG.POS.TY],

and [SET].

[13-48] TY-axis Retract Limit (Escape Position) Sensor Adjustment

At the Original_Position_TY position adjust the sensor mounting bracket position so that the

end surface of the dog and sensor are aligned along the same plane.

[13-49 ] Shuttle Jaw Opening Adjustment

1) Move the TY-axis to the forward limit and

return the jaw opening adjustment stoppers

that were removed earlier to their original

positions. Align so that the length of the

stoppers is approximately 10mm.

2) Move the TY-axis back to the

Original_Position_TY position again. Adjust

the length of the stoppers and open the

moveable claw of the jaw to a position where

the gap between the inside of the stationary

claw and the outside of the moveable claw is between 9.5 and 10.5 mm.

NOTE: Carefully adjust the balance of both stoppers.

3) Verify that the dog does not separate from the retract limit sensor as a result of the spring

force of the shuttle jaw even when the emergency stop status is activated at the

Original_Position_TY position.

NOTE: If the TY-axis moves away from the retract limit sensor as a result of an emergency

stop it is possible that the cam jaw contact is weak. However, care should be

exercised since if the contact is too strong this will increase the friction when a tray

is stored and lead to tray vibration.

4) Once adjustment is completed verify that there is no interference when the TZ-axis is moved

up and down at the Original_Position_TY position.

Tray Pusher Installation

1) With the shuttle jaw clamping the guide rollers, pull the tray plate forward and reattach the

blue duracon tray pusher before beginning adjustment.

2) While verifying that the guide rollers are securely clamped by the shuttle jaw, adjust so that

the space between the end of the tray plate and the tray pusher is between 0 and 0.5 mm.

[13-51] Tray Positioning Sensor Adjustment

Move the TZ-axis to the Original_Position_TZ height via inching and pull device position

number 101 to the forward limit position. Raise the TZ-axis another 3,500 pulses (35 mm)

from this position and then move the sensor bracket up and down to adjust the position so that

the tray positioning sensors at both corners of the tray plate detect the top of the tray plate.

Once adjustment is complete, reconfirm that the sensors respond within ± 30 pulses of the

3,500-pulse (35 mm) position.

[13-52 ] TZ-axis Interlock (Shuttle Forward Limit) Sensor Adjustment

1) With the device number 101 tray plate in the empty status, move the shuttle to the forward

limit and slowly inch the TZ-

axis to the position where the

tray add sensors come on.

2) Adjust the outside dog up and

down so that the interlock

sensor gets blocked and also

the tray add sensor turns ON

at the same time.

(The interlock sensor become

OFF because of Nozzle change.)
