Attach the conveyor stoppers on the right side when the PWB feeding direction is L to R; attach

them on the left side when the PWB feeding direction is R to L. When conveyor stoppers are used,

the PWB is clamped at the position where the front end of the PWB comes in contact with the

conveyor stopper on the downstream (i.e. OUT) side.

1) When a board is loaded to the machine, and the IN sensor ① detects it, the conveyor motor

⑩ drives the drive shaft ⑪ to cause the conveyor belt to start transporting it. Additionally, the

stopper 19 turns ON at the same time.

2) When the PWB reaches the stopper 19, the STOP sensor 18 detects it and the support tables

13 and 14 move up. At this time, the outer shape of the PWB is fixed by the stopper 19 and

support pin. After the PWB has been fixed temporarily, the stopper 19 turns OFF to finish fixing

the PWB.

3) After the PWB has been fixed, the next PWB is carried in in the same manner and it waits at the

position of the WAIT sensor 3.

4) When the system finishes producing a PWB, the fixed board (PWB) starts being ejected.

5) When the first PWB passes through the C-OUT sensor 5, the stopper 19 turns ON again to

make the preparations for fixing the next PWB.

Adjusting the PWB transport rail width

(1) Select the “Product” button from the main menu, the [Support] command, and then the [Plan

support] command.

(2) Adjust the conveyor width.

When you press the <Auto-width conveyor> button, the “Automatic conveyor width adjustment”

screen appears.

The operation for “Automatic board width adjustment” varies depending on the conveyor lane

configuration, a single-lane conveyor or a dual-lane conveyor.

CAUTION

When you click the <Move> button with following the instruction below,

the conveyor starts operating. Before clicking this button, be sure to

check to see if there is no obstacle in the conveyor movable section.

1) Automatic board width adjustment

③ Select the <Move> button to adjust the conveyor width.

The motor rotates and the machine adjusts the conveyor width.

④ Check to see if a PWB is transported with the conveyor smoothly.

②

Enter the desired value into the

“Y Size” field and the “Margin

width” field respectively.

(If the conveyor width is not

appropriate for a board to be

transported, be sure to enter

the appropriate value into the

“Margin width” (the allowable

input value range: from - 0.5

mm to 0.5 mm).

①

Select the <Origin width>

button to return the conveyor to

its origin.

Adjusting the shape clamp reference

(1) Select the “Product” button from the main menu, the [Support] command, and then the [Plan

support] command.

When you press the <Conveyor control> button, the “Conveyor control” screen appears.

(2) Turn the stopper ON.

Select “Conveyor Stopper” and press the <ON> button.

(3) Push the PWB to be produced until it comes in contact with the stopper.

If the PWB has a notch, etc. at the contact point and the contact status is unstable, make

adjustment by loosening the two screws at the root of the stopper and moving the stopper by

hand.

(4) Arrange the support pins.

Place the support pins on the support table suitably according to the PWB to be produced. Placing

support pins under a QFP and other components which require high precision of placement

improves the precision.

(5) After adjustment, press the <CLOSE> button on the “Conveyor control” screen to finish

conveyor control.

CAUTION

The shape clamp reference position is the origin (i.e. a reference point) of

the PWB coordinates of the program data.

Consequently, when the stopper position has been adjusted, make sure

to reset it following Section 2.7.1.4 “Adjusting the shape clamp reference

position”.

The PWB origin can be changed by the “PWB data” in the production

program. (See Section 4.3.3. “PWB data” of Chapter 4).

CAUTION

While the machine is operating, NEVER insert your hand, head, etc.

inside the machine.

Loosen the screw.
