3.7.2 Structure of the flexible PCB dual conveyor
The flexible dual conveyor has two conveyor tracks that are electrically and mechanically inde-
pendent of one another. The fixed conveyor sides are both "outside" as a default. As an option,
the fixed conveyor sides can be selected as right/right or left/left. The PCB dual conveyor can also
be operated as a single conveyor, as an option.

3.7.2.1 Flexible PCB dual conveyor - lanes and types
The right-hand conveyor lane (viewed in the direction of transport) is known as "conveyor 1" while
the left conveyor lane is termed "conveyor 2" (see fig. 3.7 - 3
, page 145 ).

3.7.2.2 PCB dual conveyor in "single conveyor" (optional) mode
The dual conveyor can be configured online to create a single conveyor. One conveyor lane is
moved together completely and is disabled (see fig. 3.7 - 2
). This gives a conveyor track width of
up to 460 mm.

3.7.2.3 Asynchronous transport mode
In asynchronous mode, only one board on a conveyor lane is processed. At the same time, an-
other board on the second conveyor lane is moved into the placement position. This saves the full
conveying time of one board, thus considerably increasing performance, particularly for boards
with a short cycle time. Once the placement machine has received the job data (panel, setup), the
boards on the input conveyors are continuously transported to the available processing conveyor
(provided that the processing conveyor is free) throughout the placement operation. The place-
ment process begins as soon as a board is transported into the processing area. The PCBs are
processed one after another.
If the placement sequence is interrupted, the conveyor interface will be disabled and the PCBs
currently on the processing belts will be completed.
The conveyor interface is disabled or enabled simultaneously for both transport tracks.
