FLEXIBLE ASSEMBLY SYSTEM FAS200
User Manual for FAS200 - 57 -
The need for appropriate checks to determine which type of cover is to be
assembled at each module cycle means that this module is one of the most
complex in terms of the operations to be carried out. It is also essential that the
module control coordinates part selection operations in accordance with the
commands supplied by the master responsible for production management
in the FAS-200.
This ninth module feeds the cover which is
the closure cap for the turning mechanism,
and verifies its material, color and height.
Then, the next module rejects the cover or
places it onside the housing of the body on
the pallet, depending of the signals “metal
cover”, “plastic cover”, “black cover”, “white
cover”, “tall cover” and “short cover”.
The confirmation of the cover is the correct
one (material, color and height) is got by
some sensors (an inductive detector, a
photoelectric detector and a pneumatic
cylinder with stroke reading) turning on
some internal flags of the PLC, the
previously mentioned signals.
Figure 61: Manipulators of the ninth module.
This operation begins when the pallet is positioned opposite the tenth module,
held in a determined location by a stopper on the linear transfer. Confirmation
that the pallet is in the correct position is provided by a microswitch which sends
the appropriate signal to the PLC of the tenth module which in turn sends the
signal “start cycle” to the PLC of this ninth module.
