There are two conveyor modes: Dual conveyor synchronous and "Dual conveyor asynchronous".
Enter the conveyor mode you wish to use in the machine data (konfig.ma).
3.12.3 Defining the conveyor tracks
The right transport track (viewed in the transport direction) is designated "Transport 1" and the
left as "Transport 2" (see Fig. 3.12 - 1
).

3.12.5 Asynchronous transport mode
3.12.6 Description
In asynchronous mode, only one PCB in a transport track is processed. At the same time,
another PCB in the second transport track is moved into the placement position. This saves the
full conveying time of one PCB, thus considerably increasing performance, particularly for PCBs
with a short cycle time.
3.12.7 Function
Once the machine has received the job data (panel, set-up), the PCBs on the feeding belts are
continuously transported to the available center conveyor (provided that the center belt is free)
throughout the placement operation. The placement sequence starts as soon as a PCB has
moved onto the center belt. The PCBs are processed one after another.
PLEASE NOTE 3
The components to be placed and the width of the PCBs must be identical on transport track 1
and 2. 3
If the placement sequence is interrupted, the conveyor interface will be disabled and the PCBs
currently on the center conveyor will be completed.
The conveyor interface is disabled or enabled simultaneously for both transport tracks.

3.12.8 Synchronous transport mode
3.12.8.1 Description
In synchronous mode, two PCBs of the same size are simultaneously moved to the placement
position. They must be processed as a common panel.
In this way, the top and bottom of a PCB can be processed on a single line, and the time required
to transport the PCB is shorter since two PCBs are always transported at the same time.
3.12.8.2 Function
PCBs on conveyor tracks 1 and 2 are moved synchronously onto the conveyor sections (i.e. the
conveyors are controlled synchronously, but independently of one another). The components to
be placed on conveyor tracks 1 and 2 must be organized into a panel via two subpanels. (See
the SIPLACE Pro computer user manual).
If only one conveyor track (or center conveyor) is full when the placement sequence starts, the
subpanel on this section will be identified as “not for placement”.

3.12.10 Maintenance
The individual conveyor belts and the additional lifting table require the same maintenance as the
standard conveyor. Each conveyor belt must be maintained as described in the maintenance
instructions.
