3.4 Adjusting the conveyor unit setup
When the board type to be produced is changed, the conveyor unit setup must be adjusted, and the feeders
prepared to match that board type. This section describes how to change the conveyor unit setup.
Board clamping method
Select "Edge Clamp" for the board clamping method. This method clamps a board by pushing up its edges against the
board hold plates. Push-up pins are also used to support the board at points other than its edges.

Place the push-up pins in the correct positions on the push-up plate.
Push-up pins are attached on the push-up plate by magnet. Considering the shape and size of the
board, place the push-up pins on the push-up plate so that they uniformly support the board, including
the edge of the board.

CAUTION
The push-up pin height from the bottom of the magnet to the top of the pin shaft is set to 55mm. Do not change this
height.
c
CAUTION
Set the push-up pins in positions where they will not interfere with the conveyor rails and other parts when the push-up
plate is raised.
6
Raise the push-up plate.
Check safety and press the [Push Up A to D] buttons (for the target stage) on the Setup screen. The
push-up plate moves up to clamp the board.
7
Check that the board is uniformly clamped on the conveyor.
Lightly tap on the board and also check for warping of the board from the side. If the board is
supported evenly with no warping, the adjustment is okay.
Reference
It may be convenient to mark the positions of the push-up pins on the plate (with a label, magic marker, etc.) for each
board type.
8
Remove the board from the conveyor.
1. Press the [Push Up A to D] buttons (for the target stage) to lower the push-up plate.
2. Unlock the board flap and remove the board. Lock the board flap after removing the board.
c
CAUTION
Be sure to lock the board flap. If not locked, the sensor works to prohibit operation.
c
CAUTION
When the board flap is locked, the guide pins should fit in the board flap. Raise and lower the guide pins to make sure
that they securely fit in the board flap.

Make conveyor setup on the next transport stage.
Repeat steps 2 to 8 on all stages.
