It is this cylinder which turns an arm fitted with a suction cup used to holds the
shaft throughout the movement. As in the case of the other manipulators using
the vacuum technique, an ejector and vacuum switch are provided for the
cylinder.
Given that the operation of inserting the shaft inside of the bearing calls for a
certain precision, the pallet supporting the components and lying on the belt, is
retained by a stop cylinder.

Removal of incorrect shaft:
As mentioned earlier, this module fulfils the potential to work at a higher level of
cell management by making a choice of shaft material to be used for the
various assemblies. This means a need for some element to reject the shaft if it
is not of the type indicated, an operation carried out at the fifth index plate of
the previous module and involving a manipulator which removes the shaft from
the plate on receiving the corresponding command.
This element takes the form of a two-axis
manipulator, at the extreme end of which is a
suction cup to hold the top part of the shaft. Each
axis comprise a parallel rod pneumatic cylinder
used to lift the shaft and carry it to a removal ramp.
The shaft is held by the vacuum technique
consisting of a suction cup, ejector to create the
necessary vacuum and a vacuum switch which
sends a signal to the PLC to indicate that the shaft
is securely held.
