3.12 PCB dual conveyor

3.12.1 Structure

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 SIPLACE Pro computer.

Fig. 3.12 - 1 Structure of the dual conveyor

3.12.2 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.

Software Version SR.408.xx 03/2006 US Edition 3.12 PCB dual conveyor

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

3.12.4 Changing transport mode

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”.
