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 adjustment uses a motor with its own

measuring system, meaning that the PCB width can be set independently of other machine com-

ponents (e.g. the Y gantry).

The PCB width is adjusted using two width adjustment units, which are fitted in the input and output

areas. These adjustment units are moved synchronously back and forth by the drive motor, with

the help of recirculating spindles and a toothed belt.

In the dual conveyor, the fixing pins are moved out to release the clamp of the side rail. At the

same time, the side rail is fixed to the adjustment unit. After reaching the new PCB width, both fix-

ing pins move back in. The side rail is then clamped again.

In the single conveyor, the flexible rail is moved directly by the two recirculating spindles of the

adjustment units.

3.2 Preparatory Steps

► Use the software to move the conveyor sides into the position which allows you best access.

We recommend the following setting for this:

Set the two outer sides to their outermost positions at 281mm (dual) and the lane width to

160mm. The conveyor sides are then distributed as equally as possible across the conveyor

for best accessibility.

Alternatively, you can also loosen the conveyor side clamps on the dual conveyor. Read the

service manual for your machine first.

► Move the component trolley out of the machine.

► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthor-

ized reactivation. Observe the instructions in section 1.2 "Preparatory work..." [}37].

3.3 Lowering the Conveyor

Fig.9: Checking the conveyor height

► Push the gantry over the conveyor.

► Check the height of the conveyor.

To do this, use a thickness gauge to

measure the distance from the upper

edge of the gantry to the clamping rails

and belt guidances.

Perform this measurement at the four

corners of the conveyor and the center

of the clamping rails.

This distance will be 176+/‑0.2mm in

SX1/SX2 V2 machines (see also 4.1

"Measurement Log" [}53]).

Fig.10: Fastening screw

► Remove the four fastening screws(1)

of the conveyor (Allen6). Remove the

screws and their washers.

You may need to dismantle the lifting

table plates to do this. Read the service

manual for your machine first.

These fastening screws are replaced with

longer ones during installation.

The setting screws for adjusting the con-

veyor height are located underneath the

fastening screws (Allen key size 10).

Fig.11: Setting screws

The setting screws fitted may vary according

to your conveyor version. If grub setting

screws without collar(1) are used, replace

these with setting screws which have a col-

lar(2) [03104139‑xx].

To do so, proceed as follows:

► Turn all four setting screws evenly upwards by one rotation. Repeat this until the conveyor

lays on the machine frame at all points.

► Now remove the old setting screws.

► Insert the new setting screws and tighten loosely to begin with.

Before you insert the screws, clean the area around them. Even minor contamination can in-

fluence the conveyor height.

1. Grub screw with collar and a distance

plate (5mm) for the standard height

2. Grub screw with collar and two dis-

tance plates (5mm and 2mm) for the

"Thick Board "option.

3. Horseshoe-shaped 5 mm distance

plate [03104924‑xx] (for standard and

"Thick Board" option)

4. Horseshoe-shaped 2mmm distance

plate [03104937‑xx] (for "Thick Board"

option only)

► Place one horseshow-shaped 5mm distance plate (standard height) und one horseshoe-

shaped 2mm distance plate (for "Thick Board" option) under the collar of each of the all set-

ting screws.

Now tighten all setting screws until they only just clamp the distance plates but do not yet al-

ter the conveyor height.

► Now turn all setting screws one rotation more so that the conveyor is raised equally at all

points.

Repeat this until the setting screws are tight.

NOTICE

Direction of rotation

► Turn the setting screws clockwise to move the conveyor upwards.

► Turn the setting screws anticlockwise to move the conveyor downwards.

Fig.13: Fastening screw

► Insert the new, long fastening

screws(1) incl. old washers and tighten

these.

Before you insert the screws, clean the

area around them. Even minor contam-

ination can influence the conveyor

height.

CAUTION

Have you fitted everything?

► Make sure that all eight U-shaped distance plates (4 x 2mm and 4x 5mm) are fitted.

If these are not all fitted, the machine could be damaged due to the conveyor being

too high.
