3.4.1 Replacing the Drive Toothed Belt for the Width Adjustment System [00369662-xx] Modular PCB Conveyor System
Service Manual (internal version) SIPLACE HF and X Series 75
► Feed the new drive toothed belt into the machine and run it over the toothed wheels.
► Fit the flange with its recirculating spindle.
► Feed the drive toothed belt via the deflection pulleys on the stepping motor and then fit the stepping
motor.
► Fix all 3 recirculating spindles (1) with suitable screw
clamps (2), so that these can not twist out of position
and affect the parallelism.
► The screw clamps rest on the lower edge of the
mounting tub.
► Loosen the eccentric axle (1) on the deflection pulley
and relieve the tension on the drive toothed belt (2).
► Loosen the fastening screws on the mount (3) and
then lift out the stepping motor (4). This makes it eas
-
ier to feed in the drive toothed belt, later on.
► Remove the screw (1) fastening the recirculating
spindle plus flange to the base.
(Item 5 shows the view from behind)
► Pull the spindle (2) out of the hole, the drive toothed
belt (3) can now be removed via the toothed
wheel (4).
CAUTION!
Make sure that the screw clamps used as an anti-twist
lock are fixed securely.
► Remove the complete drive toothed belt from the ma
-
chine.

► Tension the drive toothed belt.
Position the measuring point of the belt tension device at the strand center in placement area 1 of
the drive toothed belt.
► Set the tension of the drive toothed belt according to the following values.
3.4.1.1
3.4.1.1 Restoring the Parallelism of the Adjustment Unit
Restoring the Parallelism of the Adjustment Unit
If a recirculating spindle has still twisted out of position with an adjustment unit (preventing the conveyor
from running parallel), the following fix can be performed:

Replacing the Stepping Motor of the Width Adjustment System [00367174-xx]
Overview
Belt tension- width adjustment
Toothed belt for the drive 30 Hz +/- 2 Hz
► Open the three screws (2) fastening the toothed
wheel (1).
The recirculating spindle (3) and adjustment unit (4)
can now be rotated by hand (hold the toothed wheel
in place and turn the recirculating spindle).
► Measure the distance of a fixed adjustment unit to the
fixed conveyor edge.
► Rotate the loose recirculating spindle (3) until the ad
-
justment unit (4) is set to this value.
► Fix this position with the 3 fastening screws (2) on the
toothed wheel (1).

Service Manual (internal version) SIPLACE HF and X Series 77
Removal/Installation
► Unplug the connection cable in the cable duct.
► Fit the new stepping motor and reconnect the system to the electrical system.
► Tension the drive toothed belt.
Position the measuring point of the belt tension device at the strand center (i.e. the longest distance
between two toothed disks) of the conveyor toothed belt.
► Set the tension of the drive toothed belt according to the following values.
1. Loosening the eccentric axle on the deflection pulley
2. Locknut on the eccentric axle
3. Fastening screws for stepping motor
4. Stepping motor
CAUTION!
Do not damage the toothed belt!
During the following removal and installation of the motor,
the toothed belt for the width adjustment drive must not
be stretched or kinked!
► Move the PCB conveyor to the position which gives
you best access to the stepping motor of the width
adjustment system.
► Move the Y gantries into the area outside the PCB
conveyor.
► Switch off the machine and secure it to prevent unau
-
thorized reactivation.

► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the eccentric axle (1) on the deflection pulley
and relieve the tension on the drive toothed belt (5).
CAUTION!
Toothed belt must not come off!
When relaxing the toothed belt, make sure the belt does
not come off (skip) the toothed disks at the 3 adjustment
units. This would cause incorrect alignment of the adjust
-
ment units. Secure these positions with a suitable tool
(screw clamp etc.).
► Remove the 4 fastening screws (3) and then lift out
the stepping motor (4).
