Abrégé anglais

ABSTRACT The invention relates to an apparatus for and a method of manipulating a plurality of articles. The apparatus preferably is a tertiary packaging apparatus capable of receiving a single-file stream of articles (21), preferably from a secondary packaging apparatus (10). The apparatus comprises a dividing element (33) for splitting a received single-file stream of articles into two or more adjacent streams and an aligning element for collating articles in adjacent streams into an aligned rank of articles.

CLAIMS
1. Apparatus for manipulating a plurality of articles, the apparatus capable
of
receiving a single-file stream of articles and comprising a dividing element
operable
to split a received single-file stream of articles into two or more adjacent
streams and
comprising an aligning element operable to collate articles in adjacent
streams into
an aligned rank of articles.
2. Apparatus according to claim 2 wherein the apparatus is a tertiary
packaging
apparatus and wherein the apparatus is structured and arranged such that it is

couplable to a secondary packaging machine.
3. Apparatus according=to claim 2 wherein an input of the apparatus is
couplable
to an output of a secondary packaging machine such that a single-file stream
of
articles output from the secondary packaging machine, is directly receivable
by the
tertiary packaging apparatus.
4. Apparatus according to any one of the preceding claims wherein the aligning
element comprises a lug for retarding the passage of secondary packages in
each of
said two or more streams such that adjacent streams of secondary packages are
arrangeable and alignable into a continguous batch.
5. Apparatus according to claim 4 comprising two co-linear lugs disposed on

separate return conveyors.
6. Apparatus according to any one of claims 4 or 5 wherein the or each lug
forms a leading lug of the contiguous batch it forms and is coupled to a lug
conveyor
mechanism.
7. Apparatus according to claim 6 wherein said leading lug additionally forms
a
trailing lug for engaging and transferring a preceding contiguous batch of
articles.

-13-
8. Apparatus according to any of claims 4 to 7 wherein the or each lug is
operable at a lower velocity than that rate of output of secondary packages
from the
secondary packaging machine.
9. Apparatus according to any of claim 8 wherein the or each lug is operable
at a
fraction of the rate of output of the secondary packing machine inversely
proportional to the number of streams formed by the dividing element.
10. Apparatus according to any of claim 10 comprising a tray conveyor for
providing
for transferring a contiguous batch of secondary packages into a tray.
11. Apparatus according to any of claim 10 comprising a tray conveyor for
providing
successive trays, each for loading with a contiguous batch of secondary
packages,
the tray conveyor being structured and arranged to flow in the opposite
direction
relative to the output flow of the secondary packaging machine.
12. Apparatus according to claim 11 wherein the transfer element and one of
said
stop bars are carried along the same return path.
13. Apparatus according to any of claims 1 to 12 wherein the dividing
element comprises a guide which is moveable alternately into a series of
position to
divide the output packages into two or more streams of secondary packages.
14. Apparatus according to claim 13 wherein said guid is moveable in a first
sequence of positions and successively moveable in a reverse sequence of
positions.
15. Apparatus according to claim 13 or 14 wherein said moveable guide is
pivotable.

-14-
16. A method of manipulating a plurality of articles, the method comprising:
receiving a single-file stream of articles; splitting the received single-file
stream of
articles into two or more adjacent streams and collating articles in adjacent
streams
into an aligned rank of articles.
17. A method according to claim 16 wherein the steps of receiving, splitting
and
aligning are carried out by a tertiary packaging apparatus and wherein the
method
comprises coupling the apparatus to a secondary packaging machine.
18. A method according to claim 16 wherein the apparatus comprises a lug bar
for retarding the passage of secondary packages in each of said two or more
streams and the method comprises arranging and aligning secondary packages of
adjacent streams into a contiguous batch.
19. A method according to claim 18 comprising transferring a contiguous batch
of
secondary packages into a tray.
20. A method according to claim 19 comprising providing successive trays, each
for loading with a contiguous batch of secondary packages.
21. A method according to any one of claims 16 to 20 wherein the step of
splitting
said two of more streams of secondary packages comprises moving a guide
alternately into a series of positions.
22. A method according to claim 21 wherein moving said guide is conducted in a
first sequence of positions and successively conducted in a reverse sequence
of
positions.

-15-
23. A packaging machine comprising a combined secondary packaging line and
tertiary packaging line having:
(a) secondary carton packaging section for packaging primary packages in
secondary packaging cartons;
(b) an assembly section for receiving the cartons containing primary packages
and assembling them into groups of cartons;
(c) a collecting section for receiving the groups of cartons and assembling
the
groups into spaced columns;
(d) a batch assembly section for receiving a plurality of columns and
assembling
them into a batch of contiguous cartons;
(e) a tray loading section for assembling each batch of cartons onto a tray;
and
(f) an off-loading section for off-loading the trays onto a pallet.
24. A machine according to claim 1 wherein sections (a) to (d) are parts of a
continuously moving conveyor system.
25. A method of packaging comprising the steps of: packaging primary
packages in secondary packaging cartons;
(m) assembling the cartons containing primary packages into groups of cartons;
(n) collecting the groups of cartons and assembling the groups into spaced
columns;
(o) assembling the columns into a batch of contiguous cartons;
(p) loading each batch of cartons onto a tray; and
(q) off-loading the trays onto a pallet.
26. A method according to claim 3 wherein the steps (a) to (d) are carried out
on
a continuously moving conveyor system.
27. A packaging system comprising a secondary packaging machine for
packaging multiple primary packages into a secondary package and a tertiary
packaging machine according to any one of claims 2 to 15, 23 or 24

-16-
28. A tertiary package loaded by the method according to any one of claims 16
to
22, 25 or 26.
