[13-33] Prior to Connecting the MTU71E

- Cable connections should be made with the power turned off.

- Connect the MTU7 unit to the machine in the zero set complete status with a magazine in the

standby status, with the TZ-axis moved to 0 pulses via inching and with the TY-axis in the

standby status at the forward limit.

- Once the unit is joined to the machine do not turn off the power until measurement of

Original_Position_TY is completed. If after the unit is connected to the machine the power

is cut and zero set is performed again there is a danger of damage resulting from contact

between the shuttle jaw and the tray holder.

Note: When MTU detachment is carried out over the course of installation or adjustment

work, always be sure that the TZ-axis position is lowered to 0 pulses beforehand using

magazine standby or the inching operation.

[13-34] MTU71E Connection

1) Use the hydraulic jack on the bottom of the safety door to raise the machine to a height at

which the lower surface of the positioning blocks on the inside of the MTU71E do not make

contact with the tips of the positioning pins on the machine.

2) Carefully move the MTU71E to the machine connection position checking that there is no

interference with the connecting cables or other parts of the unit and then align the

positioning blocks on the inside of the MTU71E with the positioning pins on the machine

side.

3) After this is completed, loosen the hydraulic jack valve to slowly lower the machine and

connect.

4) Verify that there is no gap between the top and bottom blocks and the contact surface and

check that the unit fits perfectly.

(Use a feeler gauge to confirm that the gap is within 0.03 mm.)

Note: If the bolt for adjusting the angle of orientation is loosened by mistake, adjustment must

be performed again.

[13-35 ] Tray Holder Levelness and Perpendicularity Adjustment

With the tray holders in the set status, slide each tray holder plate in order towards the

machine. Use a dial gauge to provisionally measure the degree of levelness and

perpendicularity of the tray holder in relation to the machine base.

1) Levelness (1 ~ 9) Tolerance: All tray holders within +/- 0.8mm)

* If the degree of levelness is within the allowable tolerance

Level adjustment is unnecessary. Proceed to perpendicular measurement.

* If the front to back angle of orientation is raised in front

Loosen the angle adjustment bolt on the bottom of the unit to bring the front and back

measurement values within tolerance. (The front and back values should be adjusted as

close to zero as possible.) Furthermore, since the levelness of the tray holder extracted here

is taken into account, ignore the provisional level obtained in the previous process and

proceed with adjustment. The same also applies to the cases mentioned hereafter.

* If the left to right angle of orientation is not within the allowable tolerance range

Adjust the levelness until it is within the allowable tolerance by inserting spacers between

the ball screws on the left and right front side.

Once the levelness falls within the allowable tolerance range, proceed to the adjustment of

perpendicularity.

2) Perpendicularity (10 ~ 11) Tolerance: 0~ +/- 0.3 mm

* If perpendicular measurement is within tolerance

Perpendicular adjustment is unnecessary.

* If perpendicularity of all holders is tilted in the same direction and not within tolerance

Loosen the angle adjustment bolt on the bottom of the unit to free the unit. Loosen the

MTU71E position pin block lock bolts and fine adjust the installation position of the block so

that the perpendicularity falls within tolerance. After adjustment is completed, tighten the

angle adjustment bolt on the bottom of the unit again to adjust the level in the front to back

direction to the same value as adjusted in the previous process. Lastly check the

perpendicular measurement once again.

3) Carry out level and perpendicular measurement of the trays on all ten levels to verify that all

are within the allowable tolerances.

[13-36 ] Tray Eject Bracket Width & TZ-axis Perpendicularity Check

Verify that the width of the eject bracket (inside of bracket A) on all trays is 91.6mm (+/- 0.3

mm). If the width is not within this range then correct it. Next, set the dial gauge from the

machine on the bearing reference side, move the tray up and down and measure the

perpendicularity. Loosen the mounting bolts and adjust so that the perpendicularity of all

levels is within +/- 0.1 mm.

* Be careful that the bracket is not tilted at this time.

13-37] TY Cam Clamp Bracket Adjustment

Loosen the TY cam clamp bracket and adjust so that it can pass through the center of the eject

bracket adjusted in the previous section, [15-32]. After adjustment is finished move the tray up

and down to verify that there is no interference.

[13-38 ] Tray Holder Lock Adjustment

After the tray is set, adjust so that the gap between the lock mounted on the underside of the

plate and the tray holder is 0.3 mm +/- 0.1 mm.

[13-39 ] Max, Min_Limit_Position

1) Select [PROPER], [Max/Min], and [TY] or [TZ] and

when each axis reaches the negative side or positive

side mechanical stopper position, press [SET] to

automatically enter the Proper data.

2) The [Min_Limit] and [Max_Limit] direction of each axis

is depicted in the figure below.

[13-40 ] Original_Position_TZ

1) Move the TZ-axis via inching so that device number 101 is at the discharge position and then

eject the tray at device number 101. Then inch the TZ-axis to a position where the distance

from the QP2 machine base surface to the top of the device 101 tray holder is 157 mm +/- 0.5

mm.

Note: When the TZ-axis is operated via inching it will not move if the shuttle retract limit

sensor is not on. Also note that the tray cover and tray holder axis will come in contact if

the TZ-axis is inched prior to TZ-axis interlock sensor adjustment and if it is inched when

the shuttle has discharged the tray holder from the tray rack. Exercise due caution if the

axis must be moved during adjustment.

2) In this position select [PROPER], [DEVICE], [ORG.POS.TZ], and [SET] from the operation

monitor to automatically enter the Proper data.
