[Chapter 13] MTU71E Adjustment

Note: If the by-pass key is inserted in the mechanical switch of the MFU

specifications safety door, remove the key and put it in the MTU cover.

If the key is left inserted in the MFU specifications switch this will disable

the MTU front safety door by-pass key which can lead to damage.

[13-1] Prior to Adjusting the MTU71E

- Since layered stacking of trays is possible on the MTU71E, an additional 10 to 20 part types can be

loaded on the MTU71E compared to the MTU6 (MTU6 can handle 50 to 100 types of parts).

- There is a detachable type tray remover on the changer unit that is needed for removing empty trays.

By attaching this to the placing head, empty trays can be removed in conjunction with the layered tray

stacking specifications.

- On modules that utilize an MTU71E it is possible to change from an MTU71E to an MFU. However,

when installing an MTU71E on an MFU module, additional work related to the shuttle, remover

station and Proper data measurement are required.

- When connecting the MTU71E unit to the machine, the machine should be zero set and the 100 V

power should be on before connecting the MTU71E. If zero setting is performed after connecting the

unit to the machine there is a danger of damage being caused by a collision between the shuttle jaw and

the tray holder. For details refer to the material from what to do prior to connecting the MTU up to the

measurement of Orgn. Pos. TY.

- When the MTU71E is removed from the machine always verify that the shuttle jaw and tray holder are

separated and that the shuttle jaw has been advanced forward before carrying out the removal work.

The shuttle may be damaged if the jaw is at the retract limit.

- On modules with an MTU71E installed, the maximum part size that can be loaded is 50 mm square.

This is because the width of the reject parts conveyor is 54 mm (the 4 mm difference is to take part

pickup deviation ± 2 mm into account).

[13-2] MTU Descent Speed Adjustment

Raise the MTU by the maximum stroke using the hydraulic jack then use the speed controller

beside the jack to adjust the speed so that the operation time from the opening of the hydraulic jack

valve to the end of descent is between 6 and 10 seconds.

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.
