13-45] Securing the MTU71E in place

1) Attach the guide brackets on the left and right side

of the top of the MTU7 unit and secure the unit to the

machine side.

2) After securing the guide brackets in place, secure the

positioning blocks touching the sides of the brackets

as shown in the figure below.

Note: Carefully install the guide brackets so that the MTU71E cannot twist or turn.

[13-46 ] Shuttle Jaw Installation Position Adjustment and Left to Right Angle Adjustment

1) Adjust the shuttle jaw bracket installation position so that the two guide rollers on the end

of the tray holder plate are positioned equally in relation to the left and right end of the

shuttle jaw.

2) Use the dial gauge to measure the top of the stationary side claw in the X-direction and

adjust the shuttle jaw bracket angle such that difference between ends is within tolerance.

Once adjustment is completed verify that the guide roller positions remain equally

positioned.

[13-47 ] Original_Position_TY

1) Remove the blue duracon tray pusher from the shuttle.

2) There are two stoppers for adjusting the shuttle jaw opening amount that are installed in

the vicinity of the guide rollers of the stored tray holder plate. The stopper length should

be left about 10 mm from the mounting surface. The nut does not have to be tightened.

3) Move the TY-axis to a position where the guide rollers attached to the tray holder

mechanism are able to easily pass through the inside of the shuttle jaw (jaw opening is

about 10 mm). Check that nothing is causing interference and then slowly raise the TZ-axis

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.
