.MACHINE OPERATION

1. GENERAL

Mainly consisting of a sewing machine, preset board, carriage, stacker, the AC-172N-1790 indexer is
designed to automatically carry out a series of operations starting with sewing buttonholes on the front top-
center strips of men’s shirts, etc. and ending with stacking of workpieces.

1-1. Features

1) The material feed mechanism allows the material to be fed quickly at accuratintervals.
2) The number of buttonholes or the feed to the sewing amount can be easily set or changed with the
keys on the control panel. Twenty different patterns can be stored in memory, which enables the opera
tor to quickly respond to the frequent setup changes.
3) The material is automatically fed to sewing position after it has been placed on the setting position. The
machine automatically performs a series of operations, including sewing, thread trimming and stacking.
4) The operator can set the next material to be sewn while the machine is still sewing, allowing the opera-
tor to have enough time to attend on several machines.
5) Thanks to the presetting mechanism, it is possible for the operator to attend on four machines without
causing one of them to stand idle or for the operator himself/herself to become idle when two pieces of
garment are set on.
6) The clamping mechanism clamps the material securely without allowing any slippage during the sewing
operation from inserting to stacking.
7) Buttonholes can be sewn also to the front to-center strips of ladies wear.
8) The sewing speed can be specied as desired using the variable resistor on the control panel.
9) The machine has various modes while enable self-diagnosis when an error occurs.
10) It is also equipped with a workpiece detector mechanism which eliminates a sewing start error.

CAUTION:
To avoid malfunction and damage of the machine, conrm the following.
1. Before you put the machine into operation for the rst time after the set-up, clean it thoroughly.
2. This machine corresponds to the power supply voltage 200 to 240V.
3. Never use the machine in the state where the voltage type is different from the designated one.
4. Operate the machine with the air pressure set to 0.5Mpa.

3-2. Connecting the power supply

1) Check to be sure that the power supply in use is 200 to 240 VAC.
2) First conrm that power switch in “OFF”, then
connect the power cord to the power supply.
3) Turn the power ON. Check that the blower motor is rotating.
The sewing machine is not provided with
a terminal block or the like for changing
over the voltage. As long as the power
supply in use is in the range of 200 to 240
VAC, the sewing machine can be directly
connected to the power supply.

1) Insert air hose 1 into one-touch joint 2supplied
with this unit, and x it using metal ttings or the
like.
2) Insert one-touch joint 2 into joint 3 until it clicks.
3) Set the air pressure gauge to 0.5 MPa. To adjust,
raise knob 5 of regulator 4 in direction A, and
turn knob 5 clockwise (direction C) to increase
the air pressure, or turn the knob counter-clock-
wise (direction D) to decrease the air pressure.
4) When the air pressure gauge has been set to 0.5
MPa press knob 5 in direction B until it clicks.
The sound indicates that the gauge has locked.
When bottle 6 is lled with water, be sure
to drain off the water by removing one-
touch joint 2 from regulator 4, and by
pressing drain button 7.
Drain off the water every time the ma-
chine is used , either before or after op-
eration.

4) Press the ready key to br
C
chine into the sewing state. Then, place a piece
ing the sewing ma-
ial edge
of cloth of approximately A4-size on the preset
section.
5) Actuate the preset device to start sewing.
6) Measure the distance D from the materi
al edge
to the edge of a buttonhole. Enter the measured
D
value in the eld above the K26 pictograph.
(Ini
tial value is 65 mm.)
7) Now, the positioning of the sensor is completed. Enter the desired amount of feed in C and measure the
aforementioned distance for the purpose of conrmation.
– 13 –
[Precautions to be taken in setting]
It is recommended to place the material at the location that is 65 ± 5 mm from the center of needle as far as possible.
In the case you want to set the amount of feed from the material edge to the rst buttonhole to 60 mm or
less,
in particular, place the material in the range of 60 and 65 mm from the center of needle. Sewing cannot be carried out unless the material is placed near the notch in the preset table (52 mm away from the center of needle).
60 mm or less
52 mm
55 to 65 mm
Example) In the case the amount of feed from the material edge to the rst buttonhole is set at 50 mm and
the mater
ial is placed at the location 75 mm away from the center of needle
After the material is delivered from the preset table to the carriage, the material edge is detected by the
carriage: The carriage moves to the left by 10 mm (75 - 65).
To sew the rst buttonhole: The carriage moves to the left by 15 mm (65 - 50).
In all, the carriage has to move to the left by 25 mm. However, the amount of travel of the carriage is
limited to 20 mm at the maximum. As a result, an error occurs in the aforementioned case.
In the case the edge width (normally approximately
7 mm) is smaller, the sensor may not detect the ma-
terial edge. In this case, adjust the position of the
sensor to such a position (toward the operator) that
it is able to detect the edge.

This switch prevents a malfunction when there is no
workpiece set on the machine.
If either one of two detector switches 1 detects a
workpiece, the machine is actuated.
Take care not to place anything other than the sew-
ing products or hands on detector switches 1.
If using a piece of light absorbing black material, the
detector sensor may be inoperative. In this case,
the detecting function can be inoperative by select-
ing the memory switch No .

Adjusting the amount of air to be blow while the machine is in operation is very dangerous. Be sure to turn OFF the power to the machine before starting the adjust­ment.
5) Adjusting the air blower for blowing down the workpiece
If sewing a heavy-weight material or a large-size material, fully open speed controller 1rst. If the
workpiece cannot be easily blown down, gradually loosen speed controller 2 to
increase the amount of
air to be blown properly. If sewing a light-weight material or oppy material, set speed controller 2 to the
value adjusted of a

6) Adjusting the air blower for stacking the workpiece
If sewing a heavy-weight material or a large-size material, loosen speed controller 3 and 4 to
increase
the amount of air to be blown properly.
If sewing a light-weight material, set speed controller 3 to be the value adjusted at the time of delivery
and tighten speed controller 4 to increase the amount of air to be blown.
