Thls invention relates to an automatic photographic
prints packaging apparatus and a method using the apparatus.
Photographic prints are currently transferred from the
photographic laboratory to the retailer in suitable paper
envelopes, in which the prints are simply grouped together to
form a pack.
When the retailer r~turns the prints to the customer he
oft~n provides the customer with a holder comprising
transparent pockets into which the customer inserts the
individual prints, which can hence be preserved without
.~ danger of damage.
There is currently no apparatus able to automatically
insert prints into the holder pockets, it therefore being
impossible to do this in the photographic laboratory because
of the very large number of prints handled daily. It
~ therefore follows that in their transLer from the laboratory
i~ to the retailer and from the retailer to the customer the
:, :
prints are subject to ~he risk of damage, this risk being
also pre~ent during the insertion by the customer, ~ho may
not~be able to manage thLs wi~h sufficient care.

magazine;
Figure 3 is a schematic partial cross-section through the
apparatus on the line III-III of figure 2; and
Figure 4 shows a further embodiment in the same view as

As can be seen from the figures the apparatus according
.to the invention comprisPs a struct~lre 2, which can be
: lO ideaIly divided into two parts, one relative to the feed of a
:..
packaging web 4 and the other relative to the feed of the
prints 6 and their insertion into the pockets 8 of said web.
The web 4 is formed from a sheet of transparent plastics
material folded along its longitudinal central line and
: lS comprising a~ plurality of pairs of~;transverse joining lines
10 which define packets. The transverse joining lines lO~can
consist for example of welding and gluing lines along the two
folded halves of the plastics sheet, the pockets hence being
closed :on three sides and open on the fourth side, this
.,'20 coinciding with that edge of the web opposite the ~olded
:i
edge. The :transverse joining lines 10 do not extend
throughout the~ entire :width of the web but terminate at
certain distance~ from~ that longitudinal edge opposite the
21~1 ~a5
W092~1~04~ PCT/EP92/00329
folded edge, to hence define two free flaps which can be
opened out to facilitate the opening of the pocket for
inserting the prints, as will be apparent hereinafter. A
reading mark 12 is provided between the two joining lines of
s each pair.
The web 4 is wound to form a reel supported on the
~`` structUre 2 by two shoulders 14, which also delimit a table
16 for the advancement of the web, which unwinds from said
reel. Along the table 16 there are provided idle rollers 18
~o the purpose of which is to maintain the web adhering to the
table, and rubber-coated rollers 20 driven by a suitable
~' motor (not ~isible on the drawings) for driving the web 4
a, towards the end o~ the table 16, at which a transverse cutter
,,. :
22 is provided.
Along t~le advancement table 16 there is also provided a
reader~ 21 for~the marks 12, a pair of wideners 23 being
provided~in~ proximity to the~ edge corresponding to the two
widenable flaps of the web 4 in order to space said flaps
apart during the insertion stage.
To the side of the advancement table 16 there is
provided within the structure 2 a æone for sorting the prints
and~introducing them into~the pockets of the web 4.~This zone ~ -
comprises an endless; conveyor 24~for the packs of prints 6,
WO92/15044 2 ~ J 3 ~ Pcr/EPg2/oo329
consisting of a suc~ession of compartments 26, each
essentiially in the form of a tray with raised edges which is
~, hinged to the adjacent trays and secured to a pair of chains
. ~
. 28, for its movement parallel to the advancement table 16 of
the packaying web 4~
The two chains 28 extend between deviation sprockets 30,
one of which is motorized. .. :
:`:
Between the endless conveyor 2~ and the advancement
table 16 for the web 4 there is provided a rotary magazine
indicated overall by 32. This comprisas a cylindrical body 34
S~ of diameter approximately equal to the length of each
compartement 26, measured along the longitudina1 axis of the
conveyor 24, and a plurality of fins 36 extending radially
- from said cylindrical:body 34 to define a plurality of radial
`i'~ :~ 15 boxes 38. Alternat1vely, a maga2ine having its radial fins
supported not by a cylindrical body but by an endlass belt or
chain extending between deviation rollers could be provided.
. ..
In all cases, taking account of the maximum number of prints ;.
.'. constituting each order, the preferred number of radial boxes
20 is forty.
. . .
;~ The axial length of each fin 36 is slightly greater than
the~length~of the~ prints 6, whereas the width of each fin 36
is just greater than:one half the width of the prints 6, so
21~ 93~ .-

..~
that when a print is housed in a corresponding box 38, just- less than one half of it projects r~dially outwards.
As the diameter of the cylindrical body 34 of the rotary
magazine 32 is equal to the length of each compartment 26 as
stated, and as the endless conveyor 24 has its upper
rectilinear portion in the diametrical plane of said rotary
magazine, when a comp~rtment 26 faces the cylindrical body 34
.. the two adjacent compartments face the two diametxically
~ .
~ opposite horizontal boxes 38', 38". ;~
10 At these two adjacent compartments, which in relation to
:` : the operating cycle of the apparatus will be known as the
first loading compartment 26' and the second loading
compartment 26", there are fixed to the structure 2 two
`? roller inserters indi~cated overall by 40' and 4~0". Each
:15 roller inserter comprises a pair of coaxial rubber-coated . :
` ;~?~ rollers 42~, 42" :clos:e~to the rotary magazine 32 and
constantly~ coupled~to an~:electric motor, not visible on the
drawings,: for their rotation. The rollers 42', 42" are
: mounted on the same shaft 44, on which the rollers of the
,., ~
20 other inserter are moun~ed so that all the rubber coated
~: rollers can be dri~en by the same motor. :
At ~each inserter 4~0',40" there is fixed onto the shaft
44~a: pùlley 46',46"j~ which~ Via a belt 4a',48" transmits
~; W092/15~44 ~ 1 ~1 n ~ ~ PCT/EP92/0~329
~`~
rotation to a second rubber-coated pulley 50',50" spaced
. further from the rotary magazine 32. This second rubber-
: coated pull~lr ~0'~50" is mounted on an arm 52',52" hinged to
the shaft 44, so that rotary motion is transmitted from the
pulley 46',46" to the roller 50',50" independently of the
angular position of the arm 5~',52" relative to the shaft 44.
The arm 52',52" is connected by a rod 54/,5411 to an
overlying electromaynet 56',56" which depending on whether it
~` is enargized or not energized maintains the rubber-coated
roller 50',50" either raised or`resting on the pack of prints
6 positioned in the underlying compartment 26',26".
: In a po~ition aligned with the second inserter 40'1 there
~, is provided a pusher for pushing the prints 6 from the box 38
~;~ of the rotary magazine 32 into the pockets 8 of the packaging
I5 web 4.
This pusher comprlses a vertical pln 68 mounted on a
bracket 70 to which:;a~cable 72 i5 fixed and~lies parallel to
the axis of the magazine 32 between two pulleys 74,74', one
;i of which is motorized. The vertical pin 68 is secured to the
20 ~racket 70 via two inclined slots 82, which result in the pin
.~.
undergoing slight vertical movem~t before being dragged in a
horizontal direotion by the cable ~72. The inclination of
these:slots is:chosen:so that the movement of the pin towards

the packaging web takes place with the pin raised, whereas
the opposite movement towards the compartmentalized conveyor
takes place with the pin lowered.
In the illustrated embodiment the apparatus according
to the invention also comprises a sorting accessory 58 for
the prints 6, for particular packaging requirements which
will be described hereinafter. The accessory 58, which is
applied to the structure 2 in a pos1tion overlying the
;.......................................................................... :.
~ ndless conveyor 24, consists substantially of a tray 60 for
lO containing a pack of ;prints 6, and a pair of rubber-coated
, rollers 62 rotating constantly in opposite direction and
~, . .
-i mounted on arms 64 which enable them to be brought into
, ......................................................................... .
contact with or spaced ~rom the top print of the pack of
. prints contained in the tray 60.
Guides 66~are provided on both sides of the tray 60 to
accompany~he prints~6 ;into the underlying compartments of
the endless conveyor in~ the manne~ described hereinafter,
~1 a~ter they have been extracted one by one from said tray 60.
,~ : . .
The apparatus according to the invention also comprises
20 a microprocessor which controls the entire working cycle and
operates the variou;s actuators on the basis of stored logic
a~nd external signal~s~re~celved from various sensors which in
themselves do not form part~of the invention but are re~erred
' ,Z ~
wv 92/15044 2 ~ O 1~ PCT/EP92/00329
to as and when required in the following description of
operation.
For a better understanding of the operation of the
apparatus according to the inYentiOn the three dif~erent
packaging methods for achieving concertina-type packaging,
book-type packaging and packaging in the form of removable
sheets for albums will be described separately.
Concertina-type packaging:
To achieve this type of packaging, which does not require the
~, ,
~ 10 use of the sorting accessory 58, the operator ~irstly sets
;~ the chosen operating mode via the keyboard 76, and then
;:~ places the pack of~ prints 6 relative to each order on a
compartment 26 or the endless conveyor 24, and u~ing the
~` keyboard sets the total number of prints to be inserted into
15 the packaging web 4. This number can be read from the pricing
label present ~on the~processing~ envelope from which the pack
~ of prints 6 has~been~extracted, but could also be machine~
;Y~ read ;usi~ng~ a conventioDall reader not forming part of the
d'i: ~ inventionO : '
~ 2~0 In the meantime, the packagin~ web 4, the initial part
, . .
~; of which has been unwound from the reel, presents a pocket 8
aligned~with the~ second~compartment 26" of the conveyor 24
;and~with the fa~c~ing box~38" of the magazine 32, and has its
; 'j .

flaps widened because of the presence of the widener 23. The
correct positioning of the pocket 8 is ensured by the reader
21 rPading a mark 12 on the web.
In this state, which can be defined as the waiting
5 state, the rubber-coated roller 50',50i' o~ both inserters . :.
40',40" is raised and the vertical pin 68 of the pusher is .-
: .
~lowered into a position removed from the web 4.
`;When the apparatus is activated, either by the operator
or automatically on termination of the preceding packaging :
10 cycle, the compartment 26 containing the pack o~ prints 6 to .-
~be inserted is brought into the position 26', in which the
-~first inserter 40' lies. Here, a sensor halts the conveyor
24 and starts an automatic sequence comprising activation of
.,the electromagnet 56' causing the rotating rubber-coated
~`15 roller 50' to descend onto the pack of prints 6, the
ij . ,
withdrawal of the top print from the pack and its transfer
below the rub~ber-coated roller 42', the raising of the
rubber-coated roller 50' to prevent withdrawing` the next .:
q
.~
i~print, the introduction of the print 6 into the facing radial
box 38' of the rotary magazine 32 by ~he rubber-coated
.,, . : .
: rollers 42', the advancement of said magazine through one
~ step and~ the new~descent~of the rubber-coated roller SO' to
"~ ;: :repeat the :cycle on:th~e next;print, and so on until one half

;of the prints forming the pack have been transferred into the
suc~essive boxes 38 of the rotary magaZine 32. For example,
if the pack is formed from eighteen prints, the first nine,
ie thP 1st, 2nd, .... and 9th are housed in the nine boxes of
the rotary magazine 32.
On termination of this first stage a command is fed to
.~the conveyor 24 to cause it to advance through two positions.,
.~ so that the:compartment containi~g the remaining prints 6 of
~that order assume the position 26", and at the same time a
:~10 command is fed to the rotary magazine 32 to cause it to
:.:,advance through an angle equal to the complement to 180 with
~reference to the 1st print, so that on termination of this
.$~complementary rotation the free box immediately preceding
;~that occupied by the: 1st print is in a position facing the
lS compartment 26". The list print, which ~has undergone a
rotation of 180~now finds itself~ overturned: with respect ~to
its orig:inal~position:, ie with respect to the prints which :~
are st~ill contained ln the compartment 26".
At this~point the second inserter 40" is caused to start
~:;:20 a new automatic sequence comprising the descent of the
~ y
-:~y ~rubber~coated rollèr 50" onto the pack of prints for
ithdrawing~the :lOth~print, lts introduction below the ~ :
~3~ru~ber-coated rollers 42":, the raising of the rubber-coated

.
roller 50", the introduction of the 10th print into the
radial box 38" adjacent to that occupied by the 1st
(overturned) print, the operation of the motorized pulley 74
for driving the cable 72, the raising of the pin 68, its
horizontal advancement towards the packaying web 4, the
introduction of the 1st ~overturned~ and 10th prints into the
~ : ,.
~ facing pocket 8 of said web 4, the descent of the pin 68, its
. . .
; rekurn travel to the initial position, the advansement of the
packaging web 4 through one step, the advancement of the
Q ~o rotary magazine 32 through one step, the descent of the
, . . .
rubber-coated roller 50" for introducing the 11th print into
the radial box which has just been freed of the 1st print,
and the continuation of the aforedescribed automatic
r sequence, which leads to the introduction of tha 2nd
.. . .
~ 15 (overturned) print and 11th print into the next pocket 8 of
,, : .
~ the:web 4.
J ~
During this~ stage any arching of the prints can be
overcome by the presence of a longitudinal roller 78 which
: cause~ the two prints.to adhere to the surface along which
' !~ ,
20 they advance towards the facing pocket 8.
On terminatlon of the packaging cycle, ie after the 9th
overturned)~prlnt and 18th pr~lnt have been inserted into the
ninth pocket of the web 4j the~syst~em operatinq logic, which
WO92/1504~ 21~1 n 3 ~!~ PCT/EP92/00329
15 --
already knows the total number of prints to be packaged,
causes the web 4 to advance idly to the cutter 22, which
' 3 separates this packaged web portion from the remaining part
; of the web to be packaged.
Hence on termination of the packaging cycle a web
portion 4 is obtained in which the first pocket is occupied
~:' by the 1st and 10th prints, the second by the 2nd and 1lth
prints and so on until the ninth which is occupied by the 9th
and l&th prints. The two prints are mutually reversed, ie
-, .
; lO both the photographic images face outwards and are hence
visible through the side walls of the corresponding pocket,
and in addition are arranged so that after viewing the prints
~J
from one side of the ~ontinuous web port:ion 4, is is
necessary only to turn the web round to view from the other
15~ side. For this purpose if an:arrow 80 1S prlnted on the free
flaps~:of the pockets:~8:to~indicate the direction of unwinding
of~the~web: from; the~:reel, this same a~row indicates: the
direction in Which; the pockets have to be turned round to
: view the photographs in the sequence in which they have been
20 taken.
It should à;1so be noted that the apparatus of the
invsntion~ha~s:been~;describsd;with~reference to an operating
sequence in~ which ~ for~ reasons of simplicity it has been
.3~
2 1 ~

- 16 -
assumed that the various stages follow each other; in reality
however the operating sequence can comprise superimposed
stagies to reduce the average time of each packaging cycle. :
For example during the insertion of the pairs of prints into
the web pockets, the rotary magazine can be located with the
prints pertaining to another order, and in addition the web 4
can be advanced simultaneously with the return stroke of the
pin 68 and the trans~er of a print from~the compartment 26"
to the underlying radial box 38" of the rotary ~agazine 32.
Book-type packaging:
To achieve this type of packaging, the sorting accessory 58
~ .
:~has to ~e used, this being positioned above the conveyor 24. ;
The operator places the pack of prints to be book-packaged on
the~tray 60 of the sorter 58 and uses the keyboard to set the
lS total number of prints to be handled, as in the preceding
case~
On starting the:packaging cycle, the two counter- :
j.h
rotating rubber-coated rollers 62 are alternately caused to
descend onto the pack of prints, to withdraw them one by one
`i20 and place them on the two compartments 26 of the endless
~?~ ~convey~or 24, they~being spaced~apart by one compartment. The
:endless conveyor~: 24:is then made to advance until the
compartment containing the odd p~ints rèaches: the position
WO92/15044 21 Q 1 ~ 3 ~ PCT/EP92/00329
~ ' '.
. 26" and the compartment containing the even prints reaches
the position 25~. At this point the conveyor 24 is halted and
the following stages are effected in automatic sequence:
- dssc~nt of the rubber-coated roller 50' of the ~irst inserter
40' for transferring the 2nd print into the facing radial box
38' of the rotary magazine 32 in the aforesaid manner,
rotation of the rotary magazine through 180~ until the first
.; free box preceding the box occupied by the 2nd print is in -
. - :.
~ ~ront of the compartment 26", descent of the rubber-coated
:,. :, .
~ 10 roller ~0" of the second inserter 40" for transferring the .
., .
1st print into said free box, operating the pusher for
.. .. .
. simultaneously transferring the 1st and 2nd (overturned)
.. ; print into the facing pocket 8 of the web 4, advancing the
.~., ~ .:
;~ web, opera~ing the cutter 2 for séparating the various ~ :
.,,
;! 15 pockets 8 and so ~on~Again in this case operating stages can
be~superimposed ~to reduce the average time for each type of
packaging. ~ ; ~
In all cases, on termination of the packaging cycle a
., ~ ,
plurality o~ separate pockets 8 is obtained, which can all be
20 joined to~ether along a transverse edge to obtain a book in
: which~:the various pockets can be turned one by one to allow ..
the:~prints 6 to ~be~ viewed in the order in which they were
taken.

It should be noted that in this described example, as
illustrated on the drawings, the prints are ove~turned about
an axis parallel to a major side, the prints being inserted
;into the pockets of the continuous web parallel to this major
~`5 side. The result is that the continuous web is arranged with
:^ its longitudinal axis perpendicular to the overturning axis
`of the prints, the formation of the book package requiring
: .
the various pockets to be joined toyether along a ma~or side,
:ie along a side perpendicular to the longitudinal web axis
for correct viewing of the prints.
Other embodiments of the apparatus according to the
invention are possible, in particular those in which the
,:.,
.. ~ prints can be overturned about an axis parallel to ~a minor :
;~ .'
~mside instead of a ~ajor side, and/or in which the pocket-
``r ~15 formed web has its longitudinal axis parallel to the major
side instead of the minor ~ide of the pockets, and/or the .
pocket-formed web has its longitudinal axis parallel instead
9 ~of perpendicular to the pocket overturning axis. In this :
latter case, the pusher 68 for pushing the pairs of prints
20 into the pockets must move perpendicular instead of prallel .
to said overturning axis.

~; has to be used, the operator placing the pack of prints to be
packaged on its tray 60 with the image facing downwards and
the last photograph at the bottom. He then stqrts the
packaging cycle by setting on the keyboard the total number
of photographs to be handled and the number of pockets which
each album sheet has to contain.
In the first stage of the packaging cycle the sorter 58
divides the pack of prints 6 into two sub parks in which
~; groups of N prints are deposlted alternately, where N is the
-~ 10 number of pockets of each sheet. In prac'ice, the two
extractor rollers 62 are alternately caused to descend N
times onto the pack o~ prints, to transfer the first group of
, N prints into the underlying left compartment 26 of the
.~ . . .
endless conveyor 24, a second group of N prints into the
' ~ 15 underlying right compartment, a third group of N prints into
the; left compartment~ and so on, until~ the pack has been
con~umed. The~ extra~ctor is then advanced until the two
compartments 26 wlth the two sub-packs of prints are
positioned in front of the rotary magazine 32, in the
20 positions 26' and 26".
The two sub-packs are then treated in accordance with
the~already~ de~cr~ibed~concertina;pacXaging method but with
.i the following differences:

- the cutter is periodically made to cut the web of pockets
into portions of N pockets, forming th~ album sheets;
- the system logic, which has alreay memorized the number of
prints to be handled and which knows that a multiple m of
2N prints will be housed in m completely filled sheets
whereas the remaining prints will be house in another only
partly filled sheet, causes this residual number of prints
~, to be inserted into the initial pockets of the continuous
``~ web, and then advances the web to obtain the first sheet,
even if this is only partly filled.
.~ . .
.;.~ This incompletely fillad sheet will r~quire subsequent
, ~,
manual positioning of the prints in the various pockets, but
~ this represents only a slight drawback as this type of print
.~ preservation is generally used for prints which have been :
previously subjected to selection,~with the rejection of some
i~ of th~m, so that their~manual handling is in any case
invevitable.~ :
.:~
In the embodiment schematically illustrated in fiyure ~,
;~ ~ the basic principles~ of the present invention remain
; 20 unchanged, wher~as the endless conveyor is replaced by the
print sorter:58, which is necessarily present and feeds two
trays~ 80~,ao"~which face the two horizontal boxes 38',38" of
the rotary magazine 32 and are provided with two roller

- 21 ~
inserters 40',40". Here, the axis of rotation of the magazine
32 and hence the overturning ~xis of the prints 6 is parallel
to the minor side of the prints, the prints being inserted
into the pockets 8 of the web 4 in a direction perpendicular
to its longitudinal axis. For this reason, the in~erter 68
feeding the prints 6 from the boxes of the rotaxy magazine 32
to the facing pocket 8 of the web 4 moves perpendicular to
the axis of said rotary magazine, its drive cable 72 being
indicated schematically by a sashed line in figure 4~
In this embodiment, the boxes 8 are closed on the side
. opposite the print insertion side, so that the closure wall
. also forms a stop for halting the prints in a position
,~l
projecting from the respective boxes and acts as guide for
`: them during their insertion into the pockets of the web 4.
., : From the aforegoing it is apparent that the method for
packaging photographic prints~ and the apparatus for
implementing it are particularly advantageous and in
: particular~
they allow packaging to be achieved automatically with high
: 20 production rates (more than 1500 prints/hour),
-.they s.ubstantlally reduce the cost of conventional book- .
type packaging,~
they offer a considerable advantage for the customer, who
