Function description
The width is adjusted by means of a motor as programmed.
For dual conveyor systems, differing widths can be set for the two conveyor lanes. The width ad-
justment uses a motor with its own measuring system, meaning that the new PCB width can be set
independently of other machine components (e.g. the Y gantry)
. In the case of the single conveyor, the recirculating ball screws are connected directly with the
movable conveyor side. Conversion from a fixed side right to a fixed side left is not possible.
The PCB width is adjusted using the width adjustment units. These are moved synchronously back
and forth by the drive motor, with the help of recirculating ball screws and a toothed belt.
The side clamp is released by moving out fixing pins. At the same time, the side is fixed to the ad-
justment units. After reaching the new PCB width, the fixing pins move back in. The side wall is
then clamped again.
7.2 Loosening the Conveyor Side Clamps
Many tasks performed on the conveyor require that the conveyor sides are moved when the
machine is switched off. For this purpose, you can loosen the clamp of the conveyor side walls.
CAUTION
Lifting table
► The lifting table must always be lowered when the conveyor sides are moved.
NOTICE
Single conveyor
There are no clamps on a single conveyor.
► You can move the flexible side here by carefully pulling on the width adjustment
toothed belt.

CAUTION
Moving the conveyor sides
The conveyor sides are highly sensitive and should therefore if possible be moved without
releasing the brakes.
Irreparable damage could otherwise be caused to the conveyor sides.
For this reason, try the following options in the order listed:
► We recommend that you use the software to help you move the conveyor sides.
► If this is not possible, the conveyor sides of the dual conveyors can also be moved by
manually docking in the adjustment units (direct switching of valves for the width ad-
justment). Make sure that the cylinders engage in all clamping units of a particular
conveyor side. The conveyor sides can then be moved by carefully pulling the toothed
belt of the width adjustment unit.
► If this is not possible either, the brakes of the dual conveyors can manually be re-
leased using a pin. Take special care not to distort the conveyor sides.

1 Trailing cable 2 Interface connector
CAUTION
Outer conveyor sides can only be moved to center
If the outer conveyor sides are manually moved, the trailing cable could collide with the interface
connectors underneath the conveyor sides. To avoid this, observe the following points:
► The conveyor sides A, B and C may only be moved as far as the "stopper right side D"
on the outermost left edge of the lifting table plate of conveyor lane 1.
► The conveyor sides D, C and B may only be moved as far as the "stopper left side A"
on the outermost right edge of the lifting table plate of conveyor lane 2.
ð If the conveyor sides are moved using the software, this will automatically be taken
into account.

7.2.1 Manually Moving the Conveyor Sides with the Help of the Adjustment Units
Docking in the adjustment units
If you are unable to move the sides with the software (e.g. due to a sensor error), proceed as follows:
► Switch off the machine.
► Switch off the BoxPC.
► Dismantle the lifting table plate at location 3.
► Switch the machine on (without BoxPC). The machine is now supplied with compressed air.
Fig.267: Width adjustment belt (example of SIPLACE X4S
with dual conveyor shown)
► Carefully pull on the width adjustment
belt to move the adjustment units until
they are under the clamps and the short-
stroke cylinder can activate the clamps.
Fig.268: Solenoid valves (example of SIPLACE SX1 shown)
► Operate the solenoid valves (individually
if needed) using the yellow slide
switches(1). This moves the cylinders
out, which then loosen the clamps.
Fig.269: Cylinder engaged
► Make sure that all side cylinders(1)
have engaged.
 NOTICE!
The adjustment units need to be posi-
tioned under the conveyor side so that
all engage at the same time. If this is
not possible, check the parallelism of
the adjustment units. If these are OK,
the conveyor side may be distorted. In
this case, call the SIPLACE Service
team.
.
► Carefully pull on the width adjustment belt to move the conveyor side.
► Repeat these steps if needed for any other conveyor sides.
