Just like the other products that
Confiserie Bosch makes, including
chocolates, sweets, praline eggs and
chocolate-coated fruit, Wibele are
extremely fragile and so present a
real challenge for a fully automated
weighing and packing process. The
solution not only needed to be fast
and operate with close to zero product
giveaway, but also handle the fragile
product with extreme care. According to
Wolfgang Hellstern, “Before we made
our investment decision, we watched
Ishida weighers in action during visits
to other production facilities, which
gave us some idea of the technology
involved.”
The 14-head CCW-RV-GS multihead
weigher for fragile products selected
by Confiserie Bosch features gently
sloping hoppers with minimum transfer
distances and shallow angle discharge
chutes with minimal drop heights, to
ensure that the products are handled
with the utmost care. Both the hoppers
and the discharge chutes are also
fitted with removable synthetic liners
for extra cushioning and a ring shutter
underneath the discharge chute further
reduces drop distances, minimises
product collisions and optimises the
product transfer to the packaging
machine.
The weigher is fed via a belt elevator
and conveyor. A belt elevator and
feeder then transfer the biscuits via
the weigher’s dispersion feeder table
and the 14 radial feeder troughs to a
set of special curved pool and weigh
hoppers with double opening doors. The
system’s software takes just a fraction
of a second to calculate the three best
combinations, checks them again
and selects the combination of weigh
hoppers that come closest to the target
weight. The unique anti-floor-vibration
