RAPID TRANSIT CONVEYOR (RTC) MODULE
OVERVIEW
Chapter Issue 2 Oct 06 Technical Reference Manual 18.3
The rapid transit conveyor (RTC) is a programmable width conveyor system
which sets the rail width and transports boards through the machine using belts
and vanes. The system can accommodate up to three boards in the machine
at one time, thereby reducing the machine cycle time.
The RTC system consists of three sections:
• Inroad Conveyor
• Print Station
• Outroad Conveyor
Using belts, Board 1 is transported to the end of the inroad conveyor where the
board is stopped by the board stop vane.
The inroad vane is raised and the vane stepper motor drives the inroad vane to
snug the board.
The transport mechanism moves the vanes placing the board in the centre of
the print station.

Board 1 is secured with the board clamps and the board is raised to print height.
Whilst at print height, the transport mechanism moves the vanes back to the
ready position, the inroad vane is driven away from the board stop vane and the
inroad vane is lowered. Board 2 enters the machine, the inroad vane is raised
and the vane stepper motor drives the inroad vane to snug the board.
At the end of the print stroke, the print station is lowered to transport height. The
transport mechanism moves Board 2 to the centre of the print station and the
outroad vane moves Board 1 on to the outroad conveyor.
The printed board is transported out of the machine on the outroad conveyor
using belts.
In the event of the downline machine being busy, Board 1 is stopped at the end
of the outroad conveyor by the outroad board stop. Board 2 is printed and Board
3 enters the machine and is held at the end of the inroad conveyor.
