A button is detected at the button positioner.
If a button is detected by the sensor, the machine starts
fine-positioning of the button. If no button is detected,
the machine repeats index until the sensor detects a
button by means if the gear. However, no button is
detected after having continuously tried indexing a
button ten times, the machine terminates indexing and
the alarm indicator on the operation panel repeats
flashing on and off. Now, press the manual operation
switch, and the machine will re-start indexing until the
sensor detects a button.
Spinner oscillating arm origin switch 1 (hereinafter
called "A.ORG") and spinner oscillating arm forward
switch 2 (hereinafter called AFRT) each of which is
equipped with a photo-micro sensor (PM-T53B) are
sensors to detect the origin of the cam shaft.
Adjust cam follower 3 for the button clamp jaw lever
so that it is located above attaching screw 5 in two-
stepped cam 4 by turning the manual rotating shaft,
as illustrated in Fig.a. Fix AFRT 2 at the lowest position
of the slot in metal fitting A 7 of the spinner oscillating
arm.
At this time, note that sensor dog 6 should come to
the center of the sensor as shown in Fig.c.
(Caution) Notch of the shape of sensor dog 6 is
different from that of sensor dog for
BR20.
Index origin switch 1 (hereinafter called IORG) which
incorporates a proximity sensor (GXL-8F) is a sensor
to detect the stop of feeding of the feed disk.
Adjust the clearance between the periphery of Zeneva
wheel 2 and the detecting plane of the IORG to 0.8 to
1.2 mm (0.013" to 0.047")
