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 clamping the PCBs in each

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

line computer.

7.3.2 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.

7.3.3 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 con-

veying 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 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.

7.3.6 Synchronous transport mode

7.3.6.1 Description

In synchronous mode, two PCBs of the same size are moved into the placement position

together. 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.

7.3.6.2 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 user manual for the line computer).

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”.

7.3.6.3 Restrictions

If the dual conveyor is operated in synchronous mode, the ‘PCB whispering down the line’ option

is deactivated. PCB barcode operation is not supported in this mode. The ‘Global ink spot’ option

cannot be used.

7.3.7 Controlling the dual conveyor using the Single Functions menu

The online help contains information on controlling the dual conveyor and on the Single Functions

menu.

7.3.8 Automatic width adjustment on the dual conveyor

The desired conveyor width relates to both conveyors. When the command is received, the con-

veyors are set to the desired width one after another.

PLEASE NOTE 7

Automatic width adjustment is deactivated if “synchronous transport” is selected.
