[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.)

[13-53 ] Operation Check of the Tray Check Sensors

1) Empty tray detection check

With nothing loaded on the tray plate use the following command operation to verify that

operation is halted by a "No tray found" error (last stacked tray ejected): [SET], [POSITION],

specify module number, [MTU], [MOVE Dno], [101], hit return and then press START.

2) Operation check of tray add sensors

Set a 4 mm tray on the device position number 101 tray plate and execute the [MOVE Dno]

command to carry out the positioning operation. After positioning finishes, add another 4

mm tray to verify that the tray add sensors come on correctly. Execute the [MOVE Dno]

command again, lower the TZ-axis and if the positioning operation is carried out this means

the sensors are functioning properly.

3) Verify that the above operation is working properly for all devices from device position 101

through 120.

[13-54 ] Original_Position_Z1,Z2 Calibration

1) Set the nozzle jig.

2) Set the measurement jig at device position 101, execute the [MOVE Dno] command, and

carry out TZ-axis positioning.

3) Set a dial gauge on the Z-axis, lower the axis, and then set a dial gauge on the nozzle jig

luminescent disk at the position where the tip of the nozzle jig makes contact with the top of

the measurement jig.

4) Slowly raise the Z-axis to find the position at which the dial gauge needle begins moving.

5) The position at this time becomes Original_Position_Z1. Use the following command

operation to automatically enter the Proper data for this item: [PROPER], [DEVICE],

[Org.Pos.Z], [Org.Pos.Z1], and press SET.

6) Next, set the measurement jig at device position 102, use the same procedure to measure

Original_Position_Z2, and then carry out automatic entry of the Proper data using

[Org.Pos.Z2] and START.

[13-55 ] Original_position_MTU7D?_X, Y Measurement (V1.45 and later versions)

NOTE: The mark camera is used in automatic measurement. As a result mark camera

adjustment, Proper data measurement, and MTU71E Proper data measurement

must be completed beforehand.

Proper data that must be measured in advance

Machine • Mark Camera resolution MTU • Original Position TY,TZ

• Mark Read Position •Pickup Height MTU7_Z01,Z02

• Placement Height Z0

• Program Origin X0,Y0

• All other Proper data

The automatic measurement operation references the measured value of the previous level

to find the mark. Consequently the Proper data for the first level cannot be measured

automatically and thus must be measured manually. Furthermore, automatic measurement

of level 2 and higher levels cannot be executed correctly if an appropriate value is not

entered in Proper data for the first level. Accordingly in terms of the sequence of

measurement, it is necessary to begin with the manual measurement of the first level.
