Seal
Test Rig: Single machine using SCADA
interface to test seals, print a pass certificate
when appropriate and record the test information
on a PC for further analysis as well as automatically
protecting against set up or critical seal failures
during the test procedure. The test rig was designed
to control the environment of the test by controlling
motor speed, pneumatic pressures and monitoring
temperatures and flows. Installation based around
the GE Fanuc PC based SCADA system Cimplicity
and an Allen Bradley Micrologix 1500 range PLC
unit.

Add
Back Rotary - Pharmaceutical: This machine
was part of a larger line to make up batches
of pharmaceutical foil ribbons that had been
through a quality control process resulting in
rejected units being discarded. The rotary unit
then replaced the rejected ribbons into the batch
which was then placed onto an indexing conveyor
prior to banding. The machine used a Siemens
PLC unit which communicated with the machines
up & down stream.

40
station trickle impregnating machine:
Machine designed to trickle impregnate motor
windings with resin using a touch screen HMI
configured for recipe control as well as direct
operator control. The machine used an Allen Bradley
PLC. The unit loaded motor windings onto an indexing
carousel and by passing a current through the
windings to heat them up to initially 100°C;
the resin was then trickled onto the motors.
The resin was then cured by raising & then
maintaining the winding temperature to 170 °C.
This machine was designed as part of a continuous
process to produce approximately 120 completed
components per hour.

Deodorant
Capsule Project:
This machine was originally designed as an interim
solution for hand assembly of caps and to check
finished integrity and flow rate. It has 10 stations & its
expected life was 30,000 units. However, the
assembly stations are still in use today and
have assembled over 2 million units to date.
The assembly stations carry out two tests, the
first checks that the cap is sealed when the
nozzle is covered, and the second determines
the rate of flow when the nozzle is opened.

Load
Shed Trip Selector:
This machine is used in a gas pipeline installation
which has 4 pump motors in a rig; however, the
power supply is not enough to run more than 2
pumps at any one time. The system is programmed
to determine which pumps are operating and according
to a trip list sequence, shut down pumps and
or block pumps from being started. Each pump
is also equipped with a manual operator override.
The PLC unit used is an Allen Bradley PLC100
base and processor.

Muffin
Machine: De-nesting unit for a muffin
packaging line. The machine is designed to de-nest
and place 80 plastic trays a minute onto a flighted
conveyor. The conveyor indexes 4 flights at a
time. The de-nester is also required to match
position with the conveyor to ensure accurate
tray placement. A second Muffin machine was purchased
by the end user resulting in significant labour
savings on the 24/7 site.
