The component used consists of a pneumatic cylinder which moves the probe
until it touches the cover. An integral linear encoder in the cylinder sends pulses
which are counted by a quick counter input at the PLC, making it possible to
determine the distance the cylinder advances until it makes contact with the
cover. This information allows direct determination of the height of the cover.
• Material detection position:
As described above, this module offers the possibility of working with
aluminium, white nylon and black nylon respectively. To differentiate these
types, the next index plate position is fitted with an inductive detector and a
photoelectric detector which supply the necessary signals to the PLC.
Detection of the metal covers necessitates the use
of a inductive sensor, which supplies a signal when
the part detected is made of metal. The final cover
differentiation process is that between black and
white nylon, and for this purpose a photoelectric cell
as in figure is fitted. This component only detects
white-coloured nylon covers.
