11.3 Dual conveyor

11.3.1 Structure of the dual conveyor

The conveyor belts are driven by DC motors. Each center conveyor has a lifting table for clamping

the PCBs. The width of the PCB conveyor can be adjusted, either using the menu or from the line

computer. 11

11.3.2 General

As the name suggests, the dual conveyor has two tracks. These are independent of one another,

both electrically and mechanically. As standard, the fixed transport side is on the right, although

there is another variant in which the fixed transport side is on the left. 11

The transport type can be set to either “synchronous dual conveyor” or “asynchronous dual con-

veyor”. To do this, enter the transport type in the machine data (CONFIG.MA). 11

11.3.3 Definition of the transport tracks

The right-hand transport track (viewed in the transport direction) is designated “transport 1”, and

the left-hand track as “transport 2” (see Fig. 11.3 - 1). 11

11.3.4 Changing the transport type

11.3.5 Asynchronous transport type

11.3.6 Description

In asynchronous mode, one PCB is processed on one transport track, while another PCB on the

second transport track is moved into the placement position. This saves the full transport time,

greatly increasing output, particularly for PCBs with a short cycle time. 11

11.3.7 Function

If the machine is supplied with job data (cluster, set-up), at any given time during placement the

PCBs on the input conveyors are transported onto the center conveyor (if it is free). The placement

sequence starts as soon as a PCB has been transported onto the center conveyor concerned.

The PCBs are processed one after another. 11

PLEASE NOTE 11

The components to be placed, and the width of the PCBs on transport tracks 1 and 2 must be

identical. 11

If the placement sequence is interrupted, the transport interface will be disabled, and the PCBs

currently on the center conveyors will be completed. 11

The transport interface is enabled or disabled for both transport tracks at the same time. 11
