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.

Speed Controller Adjustments for the Remover
1) Remover station up/down
Adjust the speed controller for the remover station
up/down cylinder open four turns from the fully
closed status.
2) Remover air hose up/down
Adjust the air hose up/down cylinder speed controller
in the remover relay box open one turn from the fully
closed status.
3) After both speed controllers are adjusted use
I/O Y000: REMOVER UP
and Y001: REMOVER DWN
to check the up/down operation of the remover
station.
Note: The speed controllers use a meter-out system.
[13-14] Remover Station Sensor Adjustment
1) Remover station up/down check sensors
Turn I/O Y000: REMOVER UP on to raise the remover station. First, slide the sensor up from the
upper limit sensor on position toward the upper end where the
sensor goes off. Then gradually lower the sensor to find the exact
position at which the sensor comes on.
From this position lower the sensor another 1 mm and secure the
sensor in place in that position.
Follow the same procedure for the lower limit sensor.
Lower the sensor toward the end where the sensor goes off
and then gradually raise it to the position at which the
sensor comes on. Raise the sensor another 1 mm from
this position and secure it in place.
2) Remover chuck open/close check sensor
Turn I/O Y005: RMVR UNCHUCK on (jaw closed),
insert the remover in the chuck positioning pin and then
go to the I/O again and return Y005: RMVR UNCHUCK
to the off status (jaw open) for operation.
At this time the chuck jaw should be aligned along the
vertical groove in the remover and should fit securely in
the ring-shaped groove in the rear. Adjust so that the
cylinder upper limit sensor responds at the same time
as this status is achieved.
On the other hand, also verify that the upper limit
sensor does not come on if the jaw is not aligned with either of these
grooves.
3) Remover detection sensor
Adjust the sensor volume so that the sensor is on when the remover is in operation and off when
the remove is not present. Verify that there is no change in the response even if the remover
deviates in the rotation direction by the amount of slack that exists during the chucking operation.
(As a criterion the volume of the sensor located on the side of the chuck positioning pin mounting
bracket should be set to the highest value.) Verify that the detection status remains stable even if
there is only slight clamping pressure during the remover operation.
Springs should intersect
between the claws of the jaw.
