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 configuration.
Figure 16-2 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 con-
veyor 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).

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
print station, driving one of the two transport belt pulleys on the front face of the
print station.

Fixed Rail Print
Station
The fixed rail print station houses four pneumatic cylinders, 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 left hand side of the rear face of the print
station, driving one of the two transport belt pulleys on the front face of the print
station.
On the front face of the print station, two background suppressed opto’s are fitted
below the belt support web, designated Board at Left and Board at Right sensors.
Auxiliary Conveyors
Right Hand
Conveyor
The right hand auxiliary conveyor can be configured from the machine’s down-
line conveyor to the upline conveyor, by the removal of the conveyor board stop
at the end of the conveyor rail. Also, the auxiliary conveyor sensor is moved
from it’s outboard position as the downline auxiliary sensor inboard as the upline
auxiliary sensor.
Figure 16-4 Right Hand Auxiliary Conveyor
Each of the conveyor’s rails house a transport belt motor driving one of two belt
pulleys on the front face of the rail.
Two pneumatic solenoid valves, type 5/2 are fitted to the fixed rail support to
control the distribution of compressed air to the conveyor board stops.
Rail width adjustment is achieved by manually adjusting the position of the
moving rail along the conveyor guide shafts on the two bearing blocks. The rail
