The engaging/disengaging cycle allows manipulated engaging and
disengaging of angular synchronization, including the cam function, at
an accurately defined coupling position for a period of one or more
machine cycles. The ramp for the engaging/disengaging cycle can be
defined as a path. The engaging/disengaging cycle can also be started
via a digital input.
The disengaging cycle can be used in order to group products, for
example if one product is missing from a continuous product stream.
The disengaging cycle stops the drive (slave drive) at a parking position
on request, and rejoins the master drive in angular synchronism after
one or more machine cycles (product lengths).
The engaging cycle can be used, among other applications, to sort out
reject products. The function operates according to the same principle
as the disengaging cycle, although in this case the drive is coupled in
angle synchronism with the master drive from its parking position for a
period of one or more machine cycles, before returning to its exact
parking position again.
The engaging/disengaging cycle can also be used in combination with
the gearbox and the cam.
Engaging cycle:
The ejector must be active for
one machine cycle in order to
remove a reject product.
Disengaging cycle
The carousel must stop for one
machine cycle, because a product
is missing.
