pipe. Varying bevelled angles can be
accommodated. The machine undertakes
permanent ID-marking and no consumables
are used (like ink or paint).
The pipe is positioned on a conveyor with
the machine surface facing toward to the
stamping machine. Two stationery laser
detectors are mounted adjacent to the
Numtec-Interstahl GmbH, Austria, has
introduced a fully automated marking
machine based on a standard industrial
robot. The machine’s marking head is based
on single stamping needle technology and
is installed on axis number 6.
The machine is designed to apply an
identity onto the machined ends of a
marking position and are used to calculate
the diameter of the pipe.
Once the ‘marking start’ signal is received
by the marking system the robot searches
for the pipe end position by means of a
mechanical detection unit that is mounted
next to the stamping head on axis 6 of the
robot. Once the pipe position and diameter
have been established, the marking image
is stamped in a curved manner around the
machined bevelled surface. It is possible
to undertake front side and bevel marking,
with flexible character size.
If marking is required on the other end of
the pipe then it is repositioned and the
marking sequence is repeated on the other
end. The marking data, pipe wall thickness,
diameter and angle are automatically fed
into the marking machine control unit by the
host computer or via the operator panel.
Other product data – for example character
size, and shape of bevel – are manually
input via the operator panel.
