FLEXIBLE ASSEMBLY SYSTEM FAS200
This operation begins when the pallet is positioned opposite the module, held in
a determined location by a stopper on the linear transfer, and when the PLC of
the ninth module sends the signal "end cycle" to the PLC of this tenth module.
The task of placing the cover is performed on the pallet brought by the belt
conveyor and carrying the body-bearing-shaft assembly fed and assembled by
the previous modules. The cover fitting operation requires the pallet is stopped
and retained by a stopper.
INTEGRAL PARTS
The tenth module, like the others, may be divided into a series of manipulators.
Each sub-division has been made by considering it as a set of components
which performs a specific operation within the whole process carried out at the
module.
• Rejection of incorrect cover:
If the cover reaches the last-but-one index
plate position (on the previous module), and the
various material or height sensors have
indicated that it is not of the material or height
indicated by the main controller in charge of
production of the system FAS200, then it must be
rejected. This operation is effected at this
module by a two-cartesian axes manipulator,
which picks the cover off the index plate and
deposits it on a removal ramp if the corresponding
signal is received.
Figure 69: Rejection manipulator.
The manipulator comprises two pneumatic parallel rod cylinders, at the end of
which is a suction plate with three vacuum-holding cups.
