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

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 1-5 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
is secured in position by the locking thumbscrew on right hand bearing block.
Left Hand Conveyor The left hand auxiliary conveyor can be configured from the machine’s upline
conveyor to the downline conveyor, by the addition of the conveyor board stop
at the end of the conveyor rail. Also, the auxiliary conveyor sensor is moved
from it’s inboard position as the upline auxiliary sensor outboard as the downline
auxiliary sensor.
Each of the conveyor’s rails house a transport belt motor driving one of two belt

3-Stage Conveyor
Controller (M27)
The 3-Stage conveyor controller (M27) enclosure is located at the rear of the
machine above the ac power supply module (M23).
The M27 consists of a Programmable Logic Controller (PLC) for each auxiliary
conveyor. Above each PLC are the switches for selecting between 3-Stage/
single stage and fast/normal mode (Stage Conveyor Controller (M27) figure
refers).
On machine initialisation, each auxiliary conveyor PLC needs to detect the
machine ‘System Power’ and an initial ‘Downline Available’ signals before the
system starts operating. If the machine is being run in a stand-alone environ-
ment, the ‘Downline Available’ signal from the downline machine can be mim-
icked by shorting pins 1 & 2 of loom Pt No 160645 to the downline machine.
