Reads damaged bar codes
September 1st 2007 The new 500i Series bar code scanner has been launched by Leuze Mayser.
It is able to monitor the high speed flow of individual components with
skewed, damaged or dirty bar codes
Code reconstruction, integrated field
bus connectivity, simplified
installations without need of
interfacing units or gateways and simple
parameterisations are just some of the
features that make the new BCL 500i Series
of bar code readers suitable for
monitoring the high speed flow of individual
components, cartons or complete palletised
loads, enabling correct code pickup and fast
delivery to the control/monitoring station
even when the bar code is skewed,
damaged or even dirty.
Unlike simple scanning systems where
the full bar code is recognised by a single
continuous scan, the code reconstruction
technology of the 500i gathers data from
several high-speed passes, and via
bespoke Leuze software, is able to
completely rebuild the correct identity
despite a code label being misaligned or
partially damaged. Integral to the superior
data capture process is the new highperformance
lens developed specifically
for use in the BCL 500i barcode reader,
giving it a ±30° asymmetrical optical
angle of aperture creating a large
scanning field even at close range.
With a specification list that shows an
adjustable scanning rate of 800 to 1200
scans per second and a reading field of
200 by 1600mm Leuze Mayser is
targeting high-speed handlings and
transfer applications, typically those
found in component manufacture, food
processing and packaging areas, highspeed
sortation processes in distribution
warehouses as well as airport logistics.
A host of connectivity services come as
standard with the 500i scanner including
serial interfaces for RS 232 or RS 422 and
RS 485, plus additional communication
channels which can each be configured
individually as real-time Ethernet, field
bus interfaces such as ProfiBus and
Leuze's own multiNet facility for
networking applications. The nerve
centre for directly integrated
communication is a High-End 32-bit
network controller, creating benefits of
simplified wiring and a higher data rate
in practically every
case, eliminating
bottlenecks caused
by additional
interfacing units or
gateways.
As customary in
the PROFIBUS
environment, the
device can be fully
parameterised using
the field bus directly
via the control
system, alternatively it
can be addressed via a USB interface.
The parameterisation software called
'WEB- Config' features comprehensive
menu and operator prompting and
allows communication via any optional
web browser. For the user, this does
away with the effort involved in
maintaining and updating external
parameterisation and configuration
software on service laptops. The interface
is conditioned in such a way that a USB
memory stick can be used as an external
parameter memory with simultaneous
capability for performing documentation
and monitoring functions.
The 500i Series is the latest high-end,
high-speed performance bar reader to be
unveiled by Leuze Mayser in the UK and
becomes an integral part of the well
established BCL series, creating a range
that has a model to suit many
applications, whether its in a food
processing environment, low temperature
store or a distribution centre. More articles from Leuze Mayser Electronic Limited: |
