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.

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.

Figure 1-7 M27 Overview

3-Stage/Single

Stage Mode

For three stage mode, both 1/3 Stage Operation buttons must be OFF (LED

extinguished). The LCD screen on the PLC displays ‘3 Stage’ on the top line.

For single stage mode, both 1/3 Stage Operation buttons must be ON (LED lit).

The LCD screen on the PLC displays ‘1 Stage’ on the top line.

Fast/Normal Mode For a conveyor to operate in fast transfer mode, both Fast Transfers Disabled

buttons must be OFF (LED extinguished). The LCD screen on the PLC displays

‘Fst.Trans.’ on the bottom line for 5 seconds on power up or when the button

is switched to OFF.

For a conveyor to operate in normal transfer mode, both Fast Transfers

Disabled buttons must be ON (LED lit). Normal transfer mode is not displayed

on the PLC.
