4.4.5 Replacing the Conveyor Toothed Belt [00359917-xx]
Replacing the Conveyor Toothed Belt [00359917-xx]
Parts
▪ Synchroflex toothed belt 1315 long for input and output conveyor [00359917-xx]
▪ Synchroflex toothed belt 1160 long for placement areas 1 and 2 [00364847-xx]
▪ Synchroflex toothed belt 990 long for intermediate conveyor [00356851-xx]
Overview
CAUTION! Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Insert the new toothed belt (1) into the motor mount
(2) and place the belt around the toothed disk (3) of
the geared motor.
► Place the toothed belt around the toothed disk (4) of
the conveyor toothed belt and insert the toothed disk
in its mount.
► Use a rubber mallet to carefully knock the toothed
disk into position.
► Install the shim/washer (7) and the circlip (8).
► Loosely fasten the DC geared motor (5) with the 4 M3
hexagonal socket-head screws (6). The entire width
of the toothed belt must engage at the top and bottom
toothed disks.
► Tension the toothed belt (1) by moving the DC geared
motor in the fastening holes. The belt tension must be
between
10 and 15 N.
► Fit the complete motor unit.
NOTICE! After the drive unit has been installed,
you must make certain that the direction of rotation and
the conveyor speed (motor voltage) are correct.

NOTICE! The following diagrams apply to the
standard conveyor system (fixed side - right). Depending
on the conveyor side (left or right), either the hexagon
shaft guided block or the DC geared motor will be fitted.

Removal
► Move the PCB conveyor to the position which gives you best access to the conveyor belt
► Move the Y gantries into the area outside the PCB conveyor.
► Switch off the machine and secure it to prevent unauthorized reactivation.

1. Tape drive (mount)
2. Deflection pulley with slot
3. Conveyor toothed belt
The way in which the conveyor toothed belt is run around
the deflection pulley depends upon the transport area
concerned. Please observe this belt guidance during as-
sembly and disassembly. Please also bear in mind the
following differences during assembly and disassembly:
▪ The drive unit is installed at an angle (tilted), accord-
ing to the requirements of the installation site.
▪ Respective to conveyor edge, either the tape drive
(mount) or the drive unit with DC geared motor is
mounted.

► Loosen the deflection pulley (2) with the slot and re-
lieve the tension on the conveyor toothed belt (3).
CAUTION! The deflection pulleys have been as-
sembled with sliding nuts.
The screw for the deflection pulley should only be loos-
ened! If the screw is removed, the sliding nut will fall be-
hind the conveyor cheek side cover. You then need to
dismantle the cover to retrieve the nut.
► If the drive unit is installed, remove it.
► If the tape drive (hexagon shaft guided block) (1) is in-
stalled, remove the 3 fastening screws.
► Carefully pull off the tape drive (hexagon shaft guided
block) (1) or drive unit, while also gently unthreading
the conveyor toothed belt (3) through the opening in
the conveyor side.

CAUTION! Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Feed the new conveyor toothed belt (2) into the drive
unit and weave it round the deflection pulleys (3).
► Insert the tape drive (mount) or drive unit (1) with the
conveyor toothed belt (2) and fasten.

NOTICE
When replacing the belt on the passive side (tape drive without drive unit), set the track width
to 50 mm. The tape drive must be aligned towards the active side, allowing smooth axial move-
ment of the hexagonal shafts.
Legend
1. Deflection pulley with slot
2. Measuring point of the belt tension measuring device
(strand center )
► The deflection pulley, around which the conveyor
toothed belt is run, is fastened at a slot. The tension
of the conveyor toothed belt can be adjusted via this
deflection pulley.
► Position the measuring point of the belt tension de-
vice at the strand center (i.e. the longest distance be-
tween the two deflection pulleys) of the conveyor
toothed belt.
► Set the tension of the drive toothed belt according to
the following values.
NOTICE
The tension frequencies per area may vary according to the different belt guides. The belt ten-
sion always remains the same.
