Additional components to the installation
Applicators
All Focke Meler applicators controlled by 24 VDC solenoid valves (limited by
the output power) can be connected. For other devices, consult the Central
Office or your nearest Distributor.
Detection systems
The most suitable detection system (for presence of substrate or start
of pattern) will be connected depending on the work to be carried out. A
detection system can be a photocell, an inductive sensor, mechanical switch,
pedal, etc.
The connection will always be of the PNP type (switching to po).
The most common device used is the photocell (optical sensor). Two types of
photocells are mainly supplied:
It is sufficient to use the reflection photocell in most applications. Its detection
distance is 30 cm and it can be used in light or dark operation mode (wired).
The photocell with reflection optical fibre (direct reflection on the object) can
be used for applications with limited space, difficult access or with small-
sized substrates. Its detection distance is 110 cm and it can be used in light or
dark operation mode (switch).
To connect other types of devices, consult your Focke Meler Representative or
the Focke Meler Main Office.
Incremental encoder
An incremental encoder (pulse counter) is sufficient to read the line speed; it
does not need to pass through zero or need rotational direction.
Three types of encoder are available to users (200, 400 and 1000 pulses per
revolution) with two different attachment versions: for conveyor, with rolling
disc; for shaft, with elastic coupling. The conveyor bracket has a tension
system, using a torsion spring, to ensure permanent contact of the wheel on
the conveyor.
The 200 pulse model is designed to be placed directly on the conveyor of the
substrate to be glued, so that the controller works with a ratio of 1 pulse = 1
mm. In other cases, the auto-adjustment function of the encoder needs to be
used to find the right ratio.
The connection will always be of the PNP type (switching to po).
To connect other types of devices, consult your Focke Meler Representative or
the Focke Meler Main Office.
