5.2 Adjust the feeder bank position mechanically

Step 1 Attach the magnet stand bracket to the machine head.

For the machines equipped with a scan camera, use a magnet stand bracket for YS24 &

YS12. For the machines without a scan camera, use a versatile magnet stand bracket.

Figure 74

Step 2 Attach the dial gauge mini-stand (NF1300) to the magnet stand bracket, and set the dial

gauge to it.

Step 3 Zero the dial gauge on the reference side of the feeder bank.

Note:

The reference side of the feeder bank is on the right side end (viewed from the front side of the

machine).

Step 4 Correct the misalignment of the feeder bank.

1) Loosen the screws fastening the target feeder bank.

2) Loosen the screws fastening the feeder bank positioning block which is NOT on the

reference side.

3) Move the dial gauge from side to side to measure and adjust the feeder bank position

so that it is parallel to the X-axis.

4) Tighten the loosened screws.

5) Move the dial gauge from side to side again to make sure that there is no misalignment,

and then fully tighten all the loosened screws.

Parallelism to the X-axis: 0.02 mm or below (0.04 mm around the center of the feeder

bank)

Step 5 Remove the measuring tools from the machine head.

Caution:

Be sure to remove all the measuring tools.

Step 6 Attach the Pickup position adjustment tool on the machine and adjust the feeder

pickup positions.

See “4 Check and adjust the pickup positions of the feeders” for the details.

6 Adjust the optical axis direction of the feeder floating detection sensor

After the feeder bank is dismounted and reinstalled, the optical axis of the feeder floating detection

sensor may have been misaligned. Make sure to check the optical axis direction and if it is

misaligned, adjust it.

6.1 Required item

 YAMAHA standard tools

 Pickup position adjustment jigs

(It is recommended to prepare 2 sets. If you can prepare only 1 set, use a feeder as a

substitute.)

6.2 Check and adjust the optical axis direction

Adjust the optical axis direction by adjusting the position of the feeder floating detection sensor.

Step 1 Set the Pickup position adjustment jig on the both ends of the feeder bank.

When it is difficult to find the optical axis, you can move the tool a little inward from the end.

Step 2 Adjust the positions of the emitter and the receiver of the feeder floating detection

sensor.

Adjust the sensor position so that the optical axis of the sensor put through the holes of the

Pickup position adjustment jigs.

Figure 76

Step 3 Set a SS feeder to a feeder set position to make sure that the optical axis of the sensor

is not blocked by the feeder.

If it is not blocked, the sensor positions are adjusted properly.

Step 4 Remove the Pickup position adjustment jigs from the feeder bank and make sure that

no tools or parts are left inside the machine.
