6.5.10.2 Setting the Board Clamping

Setting the Board Clamping

► To check whether the board clamping is functioning properly, clamp a board with the lifting table.

Then check whether the board is clamped tightly on the side.

Tools

Setting (single and dual conveyor)

► The terminal strip may need to be modified, depending on the machine type. As the S27 only has a

maximum clamping area of 74 mm, the terminal strip needs to be fitted on the correct side. The ter-

minal strip for X series, HS-60 and D series machines needs to be set to 94 mm. Fit the terminal

strip accordingly on the gauge.

► The gauge is inserted between the actuator and the clamp.

► The actuator can now be released, moved down and then tightened again through the holes provid-

ed.

Quad lane conveyor settings

► For initial setting, follow the procedure used for the single and dual conveyors (see above). Make

sure that the long terminal strip [03076698-xx] is fitted on the 94 mm side of the "setting gauge ac-

tuator assembly".

► As two boards are clamped with the same lifting table, you need to check the clamping play for each

of the single conveyors.

NOTICE

Only in the event of problems

This setting should only be made if there are problems with the clamping.

The clamping function is set with the "Adjust gauge actu-

ator cpl" [03049740-xx].

6.5.10 Board Clamping Functions Conveyor

Service Manual SIPLACE D4/D4i 237

► The clamping actuators are delivered with a basic setting of 94.2 mm to the top edge of the conveyor

belt.

► If problems occur during board clamping (board partially or fully loose), you will need to reset the

clamp.

The cause of this problem is that there are a total of six actuators on three conveyor edges. If these

are not set accurately enough (they do not form a level), up to three actuators might have been set

incorrectly. These then need to be adjusted.

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.

(1) Conveyor belt play on the lower edge of the

clamp

(2) Distance 94.2 mm.

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.

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.

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 "6.5.10 Board Clamping Functions" [ ➙ 234])

▪ Dynamic response for board clamping of approx. 500 ms
