strip. The barcode strips are numbered consecutively in intervals of two (1, 3, 5, 7...) and each
represents 2 tracks (barcode 1 = track 1 and 2).
Components 7
Data can be read from the component reels to compare the stock of components against the quan-
tity specified in the set-up file (refill check), for example.
An audible signal is given when each dataset has been read successfully.
PLEASE NOTE 7
The component barcode reader option must be configured on the SIPLACE Pro computer.
Barcodes that start with the number 1, 2, 3, or 4 and are 4 digits long are interpreted as track bar-
codes. All other barcodes that do not start with number 1, 2, 3, or 4 are regarded as component
barcodes.

7.4 Dual conveyor
7.4.1 Structure of the dual conveyor
The conveyor belts are driven by DC motors. There is a lifting table for clamping the PCBs in each
processing area. The PCB conveyor width can either be set from the user interface or preset in
the placement program.

7.4.2 General
As the name suggests, the dual conveyor has two transport tracks, which are electrically and me-
chanically independent of one another. In the standard version, the right-hand side is the fixed
side. There is another version, however, in which the left-hand side is the fixed side.
7.4.3 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. 7.4 - 1
).
7.4.4 Changing transport mode

7.4.5 Asynchronous transport mode
7.4.5.1 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 con-
veying time of one PCB, thus considerably increasing performance, particularly for PCBs with a
short cycle time.
7.4.5.2 Function
Once the machine has received the job data (panel, set-up), the PCBs on the feeding belts are
continuously transported to the available processing belt (provided that the processing belt is free)
throughout the placement operation. The placement sequence starts as soon as a PCB has
moved onto the processing belt. 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.
