- Automatic
system for sealing a retail pack made
from corrugated E-flute board, the design of which incorporates two
platforms on the top of a shallow tray. One of these platforms also has
a fully folded hinged tab extending the length of the platform, which
acts as a spring to retain the product within the tray.
This feature has been patented. System is to seal the tabs using hot
melt adhesive.
A
right angled sealing system was designed with novel folding mechanisms
to facilitate the folding
of the patented spring feature. Cartons arrive at random to the
machine, and are
transported by a lug system which has variable pitches which change
according to the
arrival
pattern of the packed trays. Once primary folding has been completed, cartons
are
transported at 90° to complete the adhesive application and final
sealing
process.

Cartoning
system to pack a range of sleeved product into assorted
sizes and styles of cartons. Three basic product sizes were to be
packed automatically into 6 different sizes and style of cartons on the
one system.
-
Additionally,
one of the packs was to have a sloping top panel with a tapered
platform inserted in the base of the carton, to enable point of sale
display.
AHP
designed and manufactured a horizontal, 9 axis servo driven, indexing
cartoner, which
incorporates a triple chamber drop collator. The carton transport
comprises four independently
driven lug systems which aid quick size changes. Changes of tooling
together
with some manual screw adjustments are effected by using size gauges
and dial readouts,
to give
repeatability and accuracy. Construction is from durable stainless
steel, anodised aluminium
and quite extensive use of plastic materials.
A
particular feature of the design is that there are no chains in any of
transport drives.
This gives a clean operating environment together with a minimal
maintenance requirement.
This system is operating in Victoria, Australia.
