Manufacturing of Conveyor Systems for Corrugated Industry
This experience consisted of design, development, testing, and installation
of corrugated bundles in plants such as International Paper, Weyerhauser,
etc. The machines developed involved moving newly bundled corrugated boards
from one end of the plant to palletizing (stacking in prescribed patterns)
these bundles for shipment at the other end. Some examples of the machinery
are bundle inverters, elevated and non-elevated conveyors, staging conveyors,
stackers, and other handling equipment.
Waste Treatment Plant
The Waste Treatment Plant is designed to retrieve and stabiliize nuclear waste
on the Hanford reservation for DOE. The Stabilization is accomplished by suspending waste
in glass. The waste will be mixed with molten glass and the end product will be placed inside
stainless steel canisters.
This experience consisted of designing and developing mechanical handling
equipment. The equipment used were remote controlled cranes, remote controlled
rail transports, automated welding stations, door access
control and design of safety systems. SCADA system development and implementation
for process and equipment control and monitoring. Design of the manufacturing
execution system (MES) level network and applications. The MES interfaced
the control system (plant floor instrumentation) to the business systems,
this included data warehousing, product and secondary waste tracking,
inventory control, laboratory information management systems, and computerized
maintenance management systems.
Early Warning Sirens
This experience consisted of designing, programming, installation, commissioning,
and testing of a Citect HMI and two proprietary brands of early warning
sirens. The sirens used radio signals to communicate from the controller
to the siren. The controllers used serial communications to receive commands
from the HMI. ACES reverse engineered the proprietary communication protocols
used by the siren controllers and implemented siren control in the Citect
HMI.
Boxline (Click

The boxline project is a multi stage project that is remotely controlled
from a centralized control room by plant personnel. A crane is used
to load a metal or wooden box containing radioactive material in
the clamping frame. Once the box is clamped in the clamping frame,
the crane picks up the box and clamping frame and sets them in the
tipping yoke where the materials are emptied. The boxline project
consists of a tipping yoke, clamping frame, hydraulic power pack,
amperage monitoring modules, proximity switches, and various analog
input and output modules.
MCO (Multi-Canister Overpack) Loading System (MLS) (Click

This experience consisted of providing the control and monitoring system
programming and commissioning of the MLS. The MLS is a mechanical handling
system which consisted of a basket shuttle and a gantry system to move the
basket into the MCO. The major components of the MLS were the basket
shuttle with compressed air piston drive and a gantry with a servo motion control
system for the mast (ball screw) pick up system.
Filter Crusher (Click

The filter crusher is a fully automated system that is
controlled remotely from an HMI and is used to crush metal or wooden filters.
The filter crusher consists of a current monitoring module, proximity
switches, two jackscrews, a motor, and solenoids.
Guillotine (Click

The guillotine is a fully automated system that cuts items such
as metal beams, rebar, and other wood and metal objects into predetermined
lengths to fit into stainless steel drums. The guillotine project
consists of a hydraulic power pack, feed table, encoder, proximity
switches and other analog input and output sensors used to monitor the operation of the
guillotine and power pack.
Jibcrane (Click

The jib crane is designed to rotate 90 degrees and consists of
three tools that can be detached and reattached to the end of the crane
arm for remote operation. The three main tools are the plunger,
grapple, and electromagnetic tools. The
main purpose of the jib crane is to clear the port of the hopper
using the plunger tool when the vision system indicates the box
is full. The secondary purpose of the jib crane is to remove or
retrieve excess waste from the hopper using either the electromagnetic
tool or the multi-fingered grapple.
OWTP (Click

This project required the replacement of numerous tank and pit
level switches with ultrasonic level transmitters, the installation
of a SLC 5/05, programming of a panel View 600, installation of
a PID controller, and installation of new pump control panels.
S-112 (Click

The S-112 Project consists of a Modbus network that monitors and contols
a VFD, Water Distribution Skid, Water Distribution Nozzles, and various other
discrete and analog instruments used in the transfer of waste from the
single shell tank S-112 to a double shell tank. A Citect HMI is used by the
operations personnel to perform remote operatiing functions. Plant2Business
was used to record all data variables for future archiving and retrieval.
