Industrial Automation
We have worked with many industrial clients like Hero Honda, Honda Motors, Forbes
Gokak, MICO, Ashok Leyland, TATA BP Solar, Maruti, New Holland Tractors and Royal
Enfield, Mahindra & Mahindra, Honda, Suzuki, Bosch, TATA Motors, Alind and Prok
Devices for various industrial engineering activities and product development. Some
of the solutions provided by us to the industries are as listed below.
 Vehicle
Identification Number / Chassis Number / Engine Number marking Software
This Telesis controller interfaced software helps in the automation of vehicle manufacturing
industry. This is customized software being used by various automobile industries
across the country. We provide an easy to use system based user interface (GUI)
for the operators to punch the numbers on the engine, Id plate or chassis of the
vehicles during the production stage.
- Some of our esteemed clients are:
o. Maruti Udyog Ltd ,Gurgaon
o. Hero Honda Motors ltd., Haryana
o. Mahindra and Mahindra, Mumbai
o. Tata Motors, Jamshedpur /Lucknow
o. Ashok Leyland ltd
o. Caterpillar Ltd
o. Royal Enfield Ltd
o. Honda Motors Ltd
o. New Holland Tractors Ltd
Hand held
unit for Telesis controller interface for number punching
This hand held device takes the input from the operator directly. It negates the
dependability of the operator towards the PC. The operator hence has the freedom
to move around various models across the manufacturing unit and punch the number
on the engine or id plate etc.
Poka-Yoke
System (Automated Pneumatic Tool)
This automated screwdriver system was developed for MICO BOSCH. This system uses
controlled pressure to ensure proper torque of screws, nuts and bolts. The unit
also keeps count of number of units tightened. In case there is a mismatch in the
set number and actual number, the system gives an audio-visual alarm to indicate
the error.
Software
based automation of packaging line
The manually operated element packing and DV packing units of MICO had packaging
defects like wrong element in the wrong capsule or capsule without the element etc.
MICO wanted to eliminate those defects by automating the process of element packing
and DV line packing.
Packing GUI does the automation of the packaging process, which assists the operator
to rectify mistakes like wrong element in the wrong capsule, bottling the capsule
without the element, wrong element in the batch of elements etc. Sensors and barcode
readers are mechanically arranged to check for the above mentioned defects. Packing
GUI does the automation process by controlling (printer & printer/applicator) &
mechanical conveyor working on PLC logic. The errors occurring in the process &
the current working status are displayed on the display board interfaced to the
system.
ANDON Displays
System for Assembly Line
- ANDON display system is used to keep track of the machines performance, working.
Breakdown can quickly be notified and to the line in charge and in turn can be informed
to the maintenance people to attend the problem earliest.
The line planner sets the production of a component per hour and per shift data
in the database available in the Remote PC. Planner also configures the shift production
target of the component and the type of component being produced in the shift. The
operator can also schedule the same for any number of days using the schedule software
provided with the display board. Once the data is configured in the PC the same
i.e. production information and type of component being produced is transmitted
to the display board. Also the next rollout components are also displayed based
on the planner input.
Some of our esteemed clients are:
o. MICO BOSCH, Bangalore
o. Tata BP Solar , Bangalore
