Once the presence of a carton is detected in the trough, the carton lifter at the in-feed
assembly lifts the carton to the ceiling plate. As the carton is processed, it is held against the
ceiling plate by a series of carton support springs.
The pusher blocks advance (index) the carton downstream to station #2 where the leading
edge of the carton is lightly squeezed by a set of wheels, causing the flaps to “dome up”
allowing the opener plow to insert under the flaps. Note: cartons pause at the end of each
index.
During the next index, the pusher block advances the carton along the length of the opener
plow causing the flaps to open. Once the index is complete, the carton flaps are detected at
station #3. The flaps are detected by a set of sensors that determine that both flaps have
opened and check whether the large flap is oriented to the front (near side) or to the back (far
side) of the trough.
The next index, the pusher block advances the carton to station #4, an idle station prior to
stamping.
During the next index, the carton is advanced onto the carton support assembly at station #5,
pushing down a floating “ramp”. When the index is complete the carton support assembly is
locked into position and the stamp head cycles, applying stamps to the individual packs.
The next index, the pusher block advances the carton again onto support springs at station #6.
A mechanism at this station positions a closer horn adjacent to the small flap side (front or
back), as determined by the sensors at station #3. There is space available between station #5
(stamping) and station #6 (small flap closer) to locate an optional cancelation device.
The next index, the pusher block advances the carton along the small flap closer horn,
closing the small flap. Once index is complete, the carton pauses at idle station #7.
During the index from station #7 to station #8, the pusher block advances the carton under a
pair of glue nozzles. The appropriate nozzle (as determined by the sensors at station #3) will
apply a small amount of glue to the closed small flap.
At station #8, a mechanism similar to the one at station #6 will position a closer horn
adjacent to the large flap side (front or back) as determined at station #3.
During the next index, the exit pusher block advances the carton along the large flap closer,
pressing the large flap onto the recently glued small flap, sealing the carton. Once closed, the
carton is ejected out of the trough and onto a packing device.
