13-3] Timer Adjustment

Remove the cover from the control box on the bottom of the MTU71E and set the timer located on

the left side relay board to 0.4 seconds.

[13-4] Servo Amp Dip Switch Settings

Set the dip switches on each servo amp as shown in the figures below.

[13-5] TZ-axis and TY-axis Timing Belt Removal

1) Open the safety door on the MTU7 and loosen the belt tension adjustment pulley.

2) Remove the side cover below the empty tray removal box and remove the TZ-axis timing belt.

3) Loosen the shuttle assembly belt tension adjustment pulley and remove the TY-axis timing belt.

[13-6] Shuttle Assembly Preliminary Installment

1) Insert the MFU set rail side positioning pin on

the nozzle change unit side of the machine into

the shuttle assembly and provisionally secure

the shuttle assembly in place.

2) After provisionally securing the shuttle assembly,

connect the power cable.

[13-7] Remover Station Installation

Install the remover station on the machine base and secure in place such that the side of the base

and side of the installation bracket are roughly parallel. The bolts can be easily attached if the

remover station is raised.

MTU71E Unit Preliminary Connection

1) In the position where the MFU safety door

acrylic cover is usually installed, instead

install the remover relay box.

2) Attach the relay terminals to the machine

base and after connecting the wiring and

tubing then install the wiring and tubing cover.

3) Since zero set adjustment cannot be carried out if the MTU71E is joined to the machine,

provisionally position the unit away from the machine in either the front or rear where

adjustment can be performed. Then temporarily connect the unit to the machine using the

power extension cable for adjustment.

4) Connect the air supply and open the pneumatic valve to supply air to the unit.

[13-9] Air Regulator Adjustment

After air pressure is supplied to the unit, turn the air regulator cock until the pressure gauge

registers 0.5 Mpa.

[13-10] Remover Placement Hook Parallel and Perpendicular Alignment

Install the remover placement hook on the placing head on the machine. Set the dial gauge

needle on the outer circumference of the pin and using the side of the machine base, adjust

the bracket mounting so that the side of the hook is parallel to the machine X-axis and

perpendicular to the Z-axis.

Tolerance value: Within ± 0.03 mm of both X and Z

Also verify that the distance from the remover placement head surface to the

end of the pin is within 39 mm.

[13-11] Remover Chuck Jaw Opening Adjustment

1) As shown in the figure to the right, adjust the jaw

open/close pin position up and down with the jaw in the

open status so that the flat surface of the bottom of the

jaw is exposed by approximately 2.5 mm from the outer

circumference of the chuck positioning pin.

2) Verify the actual operation status of the remover and if

it is not stable then perform fine adjustment of the jaw

open/close pin. Ultimately the amount exposed should

be in a range from 2.5 to 3.0 mm.

3) Once adjustment is completed, lubricate all sliding

surfaces inside the remover station.

[13-12] Remover Station Perpendicular Adjustment

1) Turn I/O Y000: REMOVER UP on to raise the remover station.

2) With the remover in the actual operation status verify that

the distance from the base to the top of the remover is

293mm – 294.5mm (also that there is no interference at

the lower limit) and that the hose elbow joint is lower than

the top of the remover.

3) Attach the dial gauge to the placing head and measure 14

mm from top to bottom along the outer circumference of

the remover chuck positioning pin. While making this

measurement use the adjustment bolt on the bottom of the

remover station mounting bracket to adjust the

perpendicularity of the pin so that it is within tolerance in

both the X and Y direction.

Tolerance value: ± 0.1/14 mm

4) Verify that the ring springs used to close the remover

chuck jaw intersect between the claws of the jaw.

If springs intersect over one of the claws then correct the

position.
