Double Sheet Detectors
Roland Double Sheet Detectors are required in blank
feeders, sheet destackers, robot loaders, blank washers,
sheet conveyors, to provide tool and die protection for
stamping presses. Roland Double Metal Detectors for
steel, aluminum, or stainless steel blanks are therefore
an important precondition for press automation. Single
probe double sheet sensors can be mounted directly into
vacuum suction cups. Non-contact dual head systems are
especially well suited for roll forming application,
mechanical and magnetic transfers.

The double blank control
units of the R1000 series were designed with
a maximum of common features. They have,
e.g. the same interfaces to the PLC and the
press controls and an identical control
panel. They exhibit the following common
features:
-
Digital display of
sheet thickness and operating parameter
-
Memory for 255 double
blank parameter sets
-
Monitoring of
operating voltage and measurement time
-
Outputs for 0-sheet,
1-sheet, double blank and enable with
relay or opto coupler outputs
-
PLC interface
-
Optional fieldbus
interfaces: Profibus, DeviceNet,
ControlNet, Interbus or CANopen
-
Optional: Field
enclosure (IP65) or front panel mounting

Weld Seam Detectors
Weld seam detection and positioning in tubes with
magnetic flux leakage or eddy current sensors is
necessary in pipe and tube bending machines, or in
hydroforming presses to produce automotive
components such as exhaust manifolds, head rests,
side members, roll bars, or engine cradles.
The detection and elimination of welds when
processing coils in blanking presses, or
cut-to-length lines makes the use of lower cost
welded coils possible.

Weld Seam
Detection for Tube Bending and Hydroforming
|
The improvement of the conventional welding
methods, the widespread use of the laser
welding as well as subsequent treatments
e.g. annealing and coating have made the
automatic detection of the tube weld seam in
many manufacturing processes such as in tube
and pipe benders or hydroforming a demanding
task for modern sensor technology . This
applies both to the weld seam detection in
tubes as well as to flat stock e.g. coils.
Therefore, the use of special sensors
designed for special tasks, digital signal
analysis with microprocessor or PC-based
control systems have received
our special attention.

Cost effective
Weld Seam Detectors for 55 Gallon Oil Drums
|
A good good
number of weld seam detection tasks can be
solved with simpler systems. This applies
specifically to the detection of weld seams
in thin-walled metal packaging e.g. 55
gallon oil drums, paint cans, pails and
other general line containers or the
detection of butt welds in tinplate coils.
In such situations it is economically not
justifiable to offer technically complex
solutions. In many cases this type of
machinery process only one or few sheet
thicknesses making it uneconomical to use
systems with memories for multiple programs
or parameter sets.
