MECHANICAL DETAIL
Transport Belt
Motors
The transport belt motors drive the ‘O’ ring type transport belts which transport
the board through the machine. Each rail section has its own motor and
transport belt.
The auxiliary rail motors (4 positions) incorporate a 14:1 ratio gearbox allowing
belt speeds of approximately 500mm/sec (30m/min).
The print station rail motors (2 positions) incorporate a 4.8:1 ratio gearbox
allowing belt speeds of up to 1000mm/sec (60m/min).
NOTE
For belt speed calibration refer to the Calibration section of this chapter.
Conveyor Board
Stops
There are two types of pneumatically operated double acting cylinders fitted as
board stops to the high throughput conveyor module in three positions. The
print station and upline board stop cylinders are identical, the downline board
stop differs only in the length of stroke of the piston. These may be orientated
in one of two configurations, left to right board feed or right to left board feed.
The figure overleaf shows the positions for the board stops in either configura-
tion.
Figure 15-2 Conveyor Board Stops
Two are located at either end of the configured downline auxiliary conveyor, one
is located at the downline end of the upline conveyor.
The designated print station board stop is activated by the downline auxiliary

conveyor controller, thus preventing a board leaving the print station conveyor
whilst a board is still on the downline auxiliary conveyor. (Or when a transfer
between the downline conveyor and the downline machine is taking place.)
Each board stop is activated by the ‘Downline available’ FMI signal from the
section/machine downline of it, thus preventing a board from leaving the
conveyor until the section/machine asks for it.
CAUTION
CONVEYOR BOARD STOP.
Conveyor board stops may be damaged by the
printing of heavy boards, thus preventing the overshoot of these boards.
To minimise this effect, adjust the position of the relevant board stop
sensor if damage to the conveyor board stops occur (refer to Adjustments
and Settings section of this chapter).
Figure 15-3 Board Stop Positions
Moving Rail Print
Station
The moving rail print station is transported into position, as set by the board
width parameter in the current product file, by two drive shafts. A single stepper
motor drives the right hand drive shaft via a drive belt. Transmission between
the two drive shafts is achieved via pulleys and a drive belt.
The moving print station houses four pneumatic cylinders, two of which, are
used to operate the board clamps to secure the board against the transport belt
and the belt support web, during the print cycle. Board clamps or the optional
foil-less clamps or snugger assemblies are secured to the top of the print
station.
A transport belt motor is attached to the right hand side of the rear face of the
