Would it help your business to know the
following: How many times have you
used a spool?
How long is the cycle time for spool
return?
All this information and more can be
gained with spools that are equipped
with the data matrix chip.
The square data matrix code consists of
dots. Like the traditional barcode it can
be read out with a customary 2D laser
scanner. Besides the low costs, the data
matrix code requires less space than
conventional bar codes and has a high
fault tolerance.
Compared to the RFID technique (radio-
frequency identi cation) that works
with the help of magnetic elds, the
winding material, normally copper, does
not in uence the readability of the data
matrix. The shielding e ect of the copper
has no in uence on the code.
The data matrix chip is applied on the
ange facing of returnable spools. A
transparent, replaceable protection cover
can avoid contamination and scratches
of the marking. If it happens that the
marking is nevertheless not readable, the
protection cover can be easily replaced.
Besides the identi cation number that
can be linked clearly to a certain spool,
the data matrix code can hold further
product information. Upon speci cation,
the chip can contain a serial shipping
container number (SSCC), provided by
the customer.
The code can be read with a common 2D
laser scanner, which is usually available
in most logistics supply chains. With
the help of the customer's ERP system,
the chip can be analysed and useful
information recorded, eg the total
number of uses and duration of the
cycles.
Hafner’s strengths are individual projects
and product solutions. Besides the data
matrix chip, the company will be exhibiting
further product developments. These
include a new delivery spool with a 610mm
diameter and the precision delivery spool
10-S for the photovoltaic industry.
