TRAIN LOADING SYSTEM
Development of Control System (PLC and SCADA) for TLO - Train Loading System
Train Loaders are designed to load safely, efficiently and accurately while maximising the use of the capacity in each wagon. There are Volumetric and Gravimetric (Batch) Train Loaders, for any applications that require wagons to be loaded with bulk materials. Train Loaders are easy to use with flexible options for loadout operations. Manually controlled and automated systems are available with the ability to control at local control stations or remotely (on or off site).
NEW CONTROL SYSTEM FOR TUBE BENDER
Design and implementation of new control system based on Siemens S7-1200 PLC for 10 years old HERBER Tube Bending Machine EBM-125TB.
Objective of the project is to replace existing PC/PLC based control system (very outdated) with new series PLC and Linux based PC with User Interface developed in Node-RED. Most of the control interface will be transferred to the Node-RED dashboard and will be presented on a big touchscreen display. However, joystick and some existing pushbuttons on the existing control panel will be reused. Some specific operation actions require hardware buttons due to quicker response, so it will be wired to PLC's digital inputs.
The project is ongoing and more updates are coming.
CONTINUOUS SHOT PEENING
To eliminate downtime and manual labor, we developed a new control system for a refurbished continuous shot peener in a spring manufacturing production line. In combination with a robotic arm this has led to a significant increase in production output.
CONVEYOR EFFICIENCY IMPROVEMENT
Preformed an analysis of a 4300 TPH conveyor system and identified optimisation opportunities to reduce operating costs by over 25% per year. It achieved by reduced maintenance frequency and lower energy consumption.
GRID INTERACTIVE HOT WATER SYSTEMS
Delivered a cost analysis of technology development. Researched marketing channels for implementation of the proposed technology. Identified the most viable business model in existing market conditions.
YASKAWA MOTOMAN ROBOT
We "retaught" a robotic arm from welding to handling operations and updated firmware for complete integration into the production line. Robot's electrical interface has been connected with corresponding PLCs to enable external control. The firmware has been updated for improved performance.
KITAMURA 4-AXIS CNC MACHINE
A client's CNC machine has been out of service for long time. After troubleshooting, we delivered and commissioned a fully functional 4-axis Kitamura CNC machine. During commissioning we set new parameters for all servo drives to control tool changer, spindle and pallet changer.
CONVEYOR MULTI DRIVE SYSTEM (VSD)
Delivered, tested and commissioned new parameters set for a 2.1 MW VSD system. Parameters for the ACS800 ABB system had to be readjusted to meet new equipment requirements.
GENERAL PLC DEVELOPMENT
Programmed and commissioned a variety of PLC systems to meet customer's requirements, most commonly Siemens S7 and AB ControlLogix 5000.
- Conveyor starter
- Pump starter
- Winch starter
- Shot Peener starter
GENERAL TROUBLESHOOTING OF EQUIPMENT
Equipment failure investigations. Rectifying faults by using drawings, electrical schematics and PLC programs. Most of serviceable equipment has been returned to its working condition on the same day.
- Winch starter
- VSD multi-drive system (common DC bus)
- 4-axis CNC machine
- Robotic arm
Designed, programmed and manufactured a VSD monitoring device Bigollo X1. The device connected to the network of Variable Speed Drives. It displays current alarms and actual values of the VSDs via web interface, including alarm history with a filtering option. Detailed logged trends also available for fast troubleshooting. The device currently used on a major conveyor system at client's production site.
CONTROL SYSTEM FOR PACKAGING TRANSFER TABLE
Develop a prototype of a control system for transferring table. Any prototyping project has hidden costs. Our goal was to asses the deadlines and budget requirements and only then proceed with the design and manufacturing. We have designed the control system, sourced the components and subcontracted the best electrical panel manufacturing company. The entire project has 32 electric motors which are controlled via FOX Controller. The control system has a switch for a few scenarios to achieve different package transferring patterns.
LOGGING OF WINCH TENSION
The requirement is to log winch tension during pulling electrical cable through underground cable channels and ducts. We utilised our Fox Controller to read oil pressure, display it in kN and log in a CSV file. When the CSV file is uploaded it's used for reporting to construction contractors.
