This operation begins when the pallet is positioned opposite the fourth module,
held in a determined location by a stopper and a positioner-lifter 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 fourth module
which in turn sends the signal "start cycle" to the PLC of this third module.
INTEGRAL PARTS:
The third 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.
• Bearing feeder:
The feeder which supplies the bearing is of the
gravity feed type, in that the bearings are
stored in a column so that when the bottom
one is removed (the bearing is extracted at the
moment the cycle starts), the next falls into place
under the effect of its own weight and that of the
ones above it.
In this case, there is a bearing presence sensor in the form of a microswitch

procedure. This makes it possible to determine
when the bearings loaded in the feeder have run
