5.4.6 Board Clamping Functions Conveyor Settings

Service Manual SIPLACE X Series 337

Procedure

A) Checking the clamping play:

► Move the lifting table upwards, without the board.

► With the aid of a 0.1 mm feeler gauge, check the gap between the conveyor belt and the clamp (see

graphic above).

If the gap is larger than 0.1 mm, the distance determined between the belt and clamping edge on the

actuator will need to be reset.

To do this, you need to add the current distance between the actuator and the clamping plate to the

distance between the belt and the clamping edge!

► Move the lifting table down again.

B) Setting the play on the actuator:

► Disable the clamp and move the lifting table down.

► Measure the play between the actuator and the side edge with a feeler gauge.

► Loosen the actuator screws.

► Set the distance again with the help of a feeler gauge.

Add the play for the clamp to the play for the actuator.

► Tighten the actuator screws again.

► You now need to recheck the gap between the conveyor belt and the clamp when the lifting table

has moved up. (see above)

► If a problem occurs during board clamping, recheck this setting again. We recommend that you

check this setting every three months. When cleaning the machine, always make sure that you re-

move all components from the conveyor belt.

NOTICE

Play between the terminal strip and the upper edge of the conveyor belt

The play between the terminal strip and the upper edge of the conveyor belt may not be more

than 0.1 mm.

Readjusting the Holder for the Stopper and Proximity Switch (QC)

If the fixture rail for the stopper and proximity switch is loosened or dismantled, this will need to be read-

justed.

Tools

▪ Standard tool

▪ Gauge for Stopper Setting [03067221-xx]

Performing the setting

Position of the conveyor edges with setting gauge.

1. Distance between the conveyor edges for fitting the

setting gauge

► When dismantling the belt guidance, make sure that

the slide is secured.

► Set the conveyor so that the conveyor edges are not

against one another.

Dismantling the clamping and distance rail.

► Loosen the screws (1) and dismantle the clamping

rail and the distance rail of the conveyor edge.

5.4.8 Lifting Table Functions

Lifting Table Functions

Lifting table up function

Requirements for detecting that the lifting table is up:

▪ 30-35 pulses from the incremental disc

▪ Check performed by software (see "5.4.6 Board Clamping Functions" [ ➙ 333])

▪ Dynamic response for board clamping of approx. 500 ms

Lifting table down function

Requirements for detecting that the lifting table is down:

▪ 30-35 pulses from the incremental disc

▪ Proximity switch on the lifting table cylinder

▪ Dynamic response for board release of approx. 480 ms

Fitting the stopper unit on the bracket with the help of the

setting gauge

► Position the gauge on the pins. Lift the holder and

align it to the setting gauge (in X direction and height).

► Then dismantle the setting gauge and fit the distance

and clamping rail.
