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.

[13-41 ] Guide Rail Adjustment

stopper installed on the tray holder plate LM guide and the top of the bottom side guide rail

to between 3.7 and 4.0 mm.

2) Adjust the top side guide rail so that the gap between the bottom side and top side guide rails

is 28 mm.

TY-axis Interlock Sensor Adjustment

1) Move the TZ-axis up and down while viewing the servo counter display. Measure the number

of pulses for the width of the dog on the second level above the TY-axis interlock dog (set pitch

dog) that was installed at the Original_Position_TZ height when zero set was performed.

(I/O: IN X03F "O" when tripped)

2) Return the TZ-axis to the Original_Position_TZ position and adjust the sensor by moving it

up and down so that the center of the dog aligns with the center of the sensor. After

adjustment move the TZ-axis up and down again via inching, check that the width of the

dog is equally distributed on both sides from the center of the sensor, and record the servo

count value at that time in the Adjustment Inspection Work Manual.

3) Once adjustment is completed move the TZ-axis up and down to verify that it does not collide

with any other components and then tighten the bottom side dog mounting bolts only.

[13-43 ] TY-axis Interlock Dog Adjustment (Zero Count Position)

1) Display the servo count and move the TZ-axis to the + 50 pulse position via inching.

2) Adjust the dog attached to the inside of the top set pitch dog that was adjusted in the

previous section so that the sensor comes on in this position.

(I/O: IN X03F "O" when tripped)

3) When this dog trips the sensor on during zero setting this means that movement of the TY-

axis is possible. As a result this is premised on there being no interference between the

shuttle jaw and tray holder rollers when the sensor is on. Depending on deviations in each

machine, MTU, and shuttle, the appropriate position is not limited as a rule to the 50-pulse

position. In case of deviation align in accordance with the machine being adjusted so that

the TY-axis zero set operation is carried out from the zero count position with no interference.

4) Once adjustment is finished tighten the top interlock dog mounting bolts.

5) Move the TZ-axis up and down to verify that none of the dogs interfere with the sensors.

[13-44 ] TZ-axis Interlock (Shuttle Forward Limit) Sensor Adjustment 1

1) Move the TZ-axis to the Original_Position_TZ height.

2) Temporarily secure the outside dog to the inside dog and then provisionally secure both of

the dogs to the TY-axis interlock dog mounting bracket from the previous section.

3) Lower the TZ-axis to a position 1 mm below the Original_Position_TZ height and adjust the

sensor up and down so that the inside dog trips the sensor on.

(I/O: IN X01D "X" when tripped)

Adjust the sensor

up and down.

Find the number of pulses for

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
