Electronic
Cam programmer
The components of an electronic cam system can serve as a
drop-in replacement for the mechanical components. This
electronic approach assumes a large main motor as a central
motion source, measured by an encoder. It's a standard
approach if other aspects of the machine (e.g. conveyors) need
the motor. If all motion can be replaced by electronic cams, a
small motor with an encoder or a simple pulse train may serve
as the synchronization source. Each individual
controller/drive generates its own cam motion profile, based
on its own stored program, and the common synchronization
source. Controllers can also accept electronic inputs and
assert outputs.This I/O capacity gives much greater design
flexibility and run-time decision making power to a machine
than could be achieved with mechanical components. The actual
motion may be delivered by a linear actuator or by a servo or
stepper motor coupled with a gearbox, belt, and pulley. These
components are connected with simple cables that are easily
routed over great distances. This allows the motor or actuator
to be mounted exactly where the motion is needed, eliminating
the need for drive trains. The size, power, and configuration
of the motors and drives depend on the machine requirements
and may be different for each axis.
Hot Melt Controller
Device developed for program glue points at very high speed
with elevated resolution through a simple graphic interface.
They can be used in any process wich requires precisely
counted actuation of electric output device and specifically
to control valves used in adhesive application systems (case
sealing - pallettizing - labelling - cartooning - bag making).
The outputs gives an impulse of survoltage (60V for 5 mSec) in
start of phase for guarantee a better precision of the glue
point with control of compensation in speed of opening and
closing.

Absolute Encoder
These optical encoders have been studied for satisfy all those
applications where characteristics of high reliability
mechanical and elevated electronic precision are demanded such
in terms of speed as in terms of protection. This encoder is a
non-contacting optical rotary position sensor which reports
the shaft angle within a 360 degree range. As opposed to
incremental encoders, it reports the absolute position rather
than just the change in position. When powered up it does not
require a home cycle, even if the shaft was rotated while the
power was off. Internally an infrared led flashes through a
circular bar code onto a linear array sensor ; the
microcontroller decode the image into a unique position.
