CIMMTM
Coin Inspection and Measuring Machine
The CIMM (originally developed for the ECU)
is an automated system that measures the required dimensions of coins, at a rate
of 1 per second and sorts them into two categories, according to the
result of the measurement. Clear display of the measured dimensions, in digital
and graphical form, are generated under Windows 95/98/NT Operating
Systems.
CIMM uses the most suitable non-contact measuring
technologies, as well as the best available components.
Coin Dimensions
The CIMM handles coins of all types and
materials, including bi-metal and aluminum, with outer diameters of 10
to 40 mm, inner diameters of 4 to 30 mm, and rim height of
s 1 to 3 mm.

Option
An add-on option of weighing coins, with a scale range of 0 to 40
grams and an accuracy of 0,01 gram, is available upon request.
Reports and display changes are also available upon request.
Feed Rate
The CIMM system is designed to work at a feed rate of
1 coin/second
Optics
Two laser optics devices are used to perform measurements.
Interface
The system is based on a PC controller, for which the communications between the
handling system and measurement area is kept to a minimum.
Fault Handling
The handling system immediately comes to a halt in the event of a problem with
feeding or sorting the coins, ensuring no damage to coin. It will notify the
measurement system of the problem type so the operator can be alerted and give
instructions on solving the problem.
Software
The Coin Inspection and Measuring Machine is driven by
the CIMM software, which runs on a PC under
Windows 95/98/NT/2000.
The user can choose to measure a specific coin. If the coin to be measured is not
in the database, the user can input the data relative to the new coin, by filling
in the requested parameters into the database table.
The results of the measured batch are contained in two tables:
-
Statistical results of the whole batch.
-
Measured dimensions for each coin.
Graphical histograms are also shown along with the above tables.
The measurements and the statistical results refer to the following parameters:
-
Minimum, Maximum, Mean, Ovality and Eccentricity for Outer and Inner
Diameters.
-
Minimum, Maximum and Mean for the height of the rim.
The system has the ability to allow the operator's choice of statistics and
calculations, as per particular customer requirements.
The generated reports are easily printed or transferred to Microsoft
Excel.
Reliability
The system is capable of operating up to 20 hours a day, 7 days a
week, 365 days per year, with better than 95% up-time.
Power
The system can either operate from 220V AC, 50Hz or 110V AC,
60Hz power.
Air
The system requires a minimum of 6 atm.
Documentation
The system is supplied with documentation including:
