4.3.4 Replacing the Conveyor Toothed Belt [00359917-xx]
Replacing the Conveyor Toothed Belt [00359917-xx]
Overview
► Place the toothed belt around the toothed disk (5) of
the drive shaft and insert the toothed disk into its
mount.
► Use a rubber mallet to carefully knock the toothed
disk into position.
► Fit the shim rings (6) and the circlip (7).
► Loosely fasten the DC geared motor (8) with the 4 M3
hexagonal socket-head screws (3). The entire width
of the toothed belt must engage at the top and bottom
toothed disks.
► Tension the toothed belt (4) by moving the DC geared
motor in the fastening holes. (See "6.7.1 Setting the
Tension of the Conveyor Toothed Belt and the Width
Adjustment Unit" [ ➙ 261].)
► Fit the complete motor unit.
NOTICE
After the new drive has been installed, check the direction of rotation (polarity) and the conveyor
speed with SITEST.

Legend

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 removal and installation:
▪ The drive unit is installed either horizontally or verti-
cally, according to the requirements of the installation
site.
▪ Depending on the conveyor side, either the tape drive
(mount) or a drive unit with DC geared motor will be
mounted.
► 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 unau-
thorized reactivation.
► 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 assembled 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 Unscrew the
hexagonal shaft from the conveyor frame.
► 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) or drive unit (1), while also gently unthreading
the conveyor toothed belt (3) through the opening in
the conveyor side.

▪ Lifting table unit for dual conveyors [00358654-xx]
Overview
CAUTION!
Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Feed the new conveyor toothed belt (3) into the drive
unit and weave it round the deflection pulleys (2).
► 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, allow-
ing smooth axial movement of the hexagonal shafts.
► Tighten the fastening screws.
► Adjust the belt tension. (See "6.7.1 Setting the Ten-
sion of the Conveyor Toothed Belt and the Width Ad-
justment Unit" [ ➙ 261].)
