Track allocation

Four-digit barcode strips are attached to the lateral safety screens for the purposes of track allo-

cation. The first digit is used to identify the component table (1 or 2), while the remaining three

digits specify the track number. There are also return barcodes at both ends of the barcode strip.

The barcode strips are numbered consecutively in intervals of two (1, 3, 5, 7...) and each repre-

sents 2 tracks (barcode 1 = track 1 and 2).

Components

Data can be read from the component reels to compare the stock of components against the

quantity 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 line computer or the SIPLACE

Pro.

Barcodes that start with the number 1 or 2 and are 5 digits long are interpreted as track barcodes.

All other barcodes that do not start with number 1 or 2 are regarded as component barcodes. 7

7.3 Dual conveyor

7.3.1 Structure of the dual conveyor

The conveyor belts are driven by DC motors. There is a lifting table for holding the PCBs in each

processing area. The width of the PCB conveyor can be adjusted either via the menu or using

the line computer.

Fig. 7.3 - 1 Structure of the dual conveyor

7.3.2 General

As the name suggests, the dual conveyor has two transport tracks, which are electrically and

mechanically 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.

There are two conveyor modes: "Single conveyor" and "Dual conveyor asynchronous. Enter the

conveyor mode you wish to use in the machine data (konfig.ma).

(3) Output conveyor (4) Lifting table

(5) Width adjustment

7.3.3 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. 7.3 - 1

7.3.4 Changing transport mode

7.3.5 Asynchronous transport mode

7.3.5.1 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 conveying time of one PCB, thus considerably increasing performance, particularly for PCBs

with a short cycle time.

7.3.5.2 Function

Once the machine has received the job data (panel, set-up), the PCBs on the feeding belts are

continuously transported to the available 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 7

The components to be placed and the width of the PCBs must be identical on transport track

1and2. 7

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.
