PROCESS AND APPARATUS FOR BRINGING
ARTICLES TOGETHER IN A PACKAGING MACHINE
-This application is a division of application No.
321,489.
The present invention relates to a process and an
apparatus for br~ging articles together in a packaging
machine, in particular for introducing the contents of a
package into the said package.
The problem of bringing articles together occurs
very frequently in the packaging industry. In the main,
what is involved is the introduction of the contents of the
package into the said package, which is partially finished or
open at one side. An example of a field of application which
may be mentioned in the production of cigarette packets of
the "slide and sleeve" type. The process of bringing two
articles together consists of having to introduce the slide,
filled with the package contents, into the set-up sleeve.
It is the object of the present invention to propose
a process and an apparatus forhringing articles together,
in particular for introducing the contents of a package into
the said package, which is at least partially open.
This object is achieved by the process according to
the invention, which is characterised in that the articles
to be brought together (for example the slide and sleeve) are
conveyed coaxially and with the same speed each along coaxial
circular tracks of the same diameter and are combined with one
another by axial shift of at least one of the articles.
Accordingly, the articles, for example the package contents
and the package, run parallel next to one another on circular
-1- ' ~:,
114~2t~Z
tracks and are brought together by a movement of at least
one of the articles in the axial direction.
The advantage of this process resides firstly in the
continuous method of operation, which always results in high-
er productivity of the pack`aging machine concerned. Further,
the process permits a compact construction of the relevant part
of the packaging machine, though the bringing-together of the
articles may extend over a fairly long distance of travel.
The invention further relates to a special transfer
apparatus, by means of which the articles, for example the
contents of the package, are taken from one transport track
and are fed, with acceleration, to a contilluously revolving
turret. According to the invention, the articles are, for
this purpose, moved, and accelerated; along an arc-shaped
conveyor track which is axially parallel to the turret and
are thereafter conveyed into the immediate vicinity of the
particular turret or into the track in which a pocket or a
holder thereof travels. For this purpose, the articles are
picked up by driver pockets of the transfer apparatus and are
transferred, without relative movement in the axial direction
or radial direction, to the holder of the continuously re-
volving turret.
A lifting apparatus of special construction is also
provided, by means of which the articles are lifted off a
conveyor, in particular a linear conveyor, and are fed to the
transfer apparatus.
T~e invention further relates t~an altern3tive for
feeding articles to a revolving turret, in the present case
the feeding of a flat CUt-O'It in order to form a sleeve of
1~4~2~Z~
a package of the "slide and sleeve" type. According to the
invention, a rocker, preferably driven at one end by a crank
and at thè other end by a rocker arm, is provided, which rock-
er arm is so moved by this mechanism that the article located
on the rocker (the flat cut-out) is fed in the radial direc-
tion to the periphery of the turret and for a short section
travels with the latter in the circumferential direction,
with instantaneous acceleration.
Finally, the invention relates to an erector, which
in this case is allotted to the turretfor receivxn~ the package
(sleeve). The erector, which travels with the turret for part
of the distance, folds the flat cut-out into the three- dimen-
sional shape of the package or sleeve, whilst the turret con-
tinues to move. This erector can again be employed indepen-
dently of the other features, according to the invention, of
the apparatus.
More particularly, the present invention relates to a
method for introducing objects more particulary packs, into a
circular track of a continuously rotating conveyor, preferably
into the pocket or the like of a rotating turret, comprising
feeding the said objects at a speed differing from that of the
said conveyor in which the object is accelerated, along a
moving track leading to the turret or the like to the velocity
of the said turret; and passing the said objects to the said
turret, or to a pocket therein, at a moment of equal velocity
therewith.
The present invention also provides an apparatus for
feeding or transferring individually or intermittently con-
veyed objects,more particularly packs or parts thereof, to
3~2~2
a continuously rotating conveyor more particularly to a turret
having pockets or the like, comprising a transfer device by
means of which the said objects may be passed to a conveyor
path at the outer periphery of the turret, in such a manner
that the said objects may be accelerated to the peripheral
velocity of the said turret and may be transferred to the
turret, or to a pocket therein, at a moment of equal velocity
therew.ith.

The apparatus shown in the drawings consists of several
co-operating individua~l units, which co-operate optimally but
can also be employed in other contexts. A unit 10 for bring-
ing articles together allows such articles to be combined withone another on a continuous motion basis. In the present case,
these articles are, on the one hand, a sleeve 11 and, on the
other hand, a filled slide 12 of a cigarette pocket of the
"slide and sleeve" type, shown by way of example in Figure 1.
A transfer apparatus 1~ serves to feed articles-in the present
case a filled slide 12-to a revolving turret. This transfer
apparatus 13 is preceded by a lifting apparatus 14, by means
of which the articles are transferred, from a conveyor 15,
which in the present case follows a linear path, to the lift-
ing apparatus 14. Figure 11 shows details of a rocker 16
which moves in a particular manner, again for the transfer
of articles to a revolving turret. In the present case, these
articles are flat stacked cut-outs for forming the sleeve 11.
Finally, attention snould be directed to an erector
shown in Figure 11, by means
~1~1~32
of which, whilst the turret is moving, the cut-outs picked up
by the turret, especially the cut-outs intended for the sleeve
11, can be erected.
The unlt 10 for bringing the articles together (see,
in particular, Figure 4) is a very compact structure. Two
turrets 19 and 20 are rotatably mounted on a shared main
axle 18. Each of these turrets 19, 20 serves to receive
articles which are to be combined with one another. In the
present instance, the turret 19 picks up the slide 12, con-
taining the cigarettes, in pockets 21, whilst the sleeves 11
are transported in holders 22 of the turret 20. The two
turrets 19 and 20 run continuously and at the same speed, and
in such a way that the pockets 21 and holders 22 are opposite
one another in the axial direction. The slide and sleeve are
brought together through the slides 12 being expelled by rams
23 from the pockets 21, in the axial direction, and being
pushed into the open sleeves 11 in the holders 22 of the turret
20. Accordingly, an axial shift of the slides 12 takes place
during the rotation of the turrets 19, 20.
In the present instance, the turret 19 is formed by
pockets 21 which consist solely of two lateral U-shaped side
walls 24 and 25 (Figure 2). One side wall 24 is fixed whilst
the side wall 25 is part of a pivoted lever 26. The latter
is rotatably mounted on a support rod 28 between stops 27.
Corresponding to the number of pockets 21, several support
rods 28 are arranged axially parallel to the main axis 18
and at a distance from the latter.
In order to receive the articles, namely the slides
12, in the pockets 21, the movable side wall 25 can be re-
--6
32
tracted by appropriate movement of the pivoted lever 26.
This opening and closing movement of the pocket 21 or of the
pivoted lever 26 can be controlled by an extension 29 of the
pivoted lever 26. This extension engages, by a sensor roll 30,
in a control slot 31 of a control disc 32 which is fixed,
namely mounted on the main axle 18. The support rods 28 re-
vo]ve round the main axle 18 along a circular track. During
this revolution, the opening and closing movements of the
pocket 21 are derived from the control slot 31 via the sensor
roll 30.
Guide rods 33 are located at a distance from the
support rods 28 and parallel to the latter. These guide rods
and the support rods 28 each respectively serve as a sliding
mounting for the ram 23 or an arm 34 thereof. The ram 23 can
as a result slide exclusively in the axial direction on the
support rod 28 and the guide rod 33.
In order to execute the controlled reciprocating move-
ments of the ram 23, the end of the arm 34 is provided with a
sensor roll 35, located in a control slot 36 on the periphery
of a control drum 37. This control drum is also fixedly mount-
ed on the main axle 18. The dimensions of the ram 23, and of
the head 38 thereof, are such that this part can move between
the side walls 24 and 25 of the pocket 21.
The turret 20 is formed by a turret plate 39, which
is rotatably mounted on the main axle 18. The holders 22 are
formed on the outer periphery of the turret plate 39, in
identical arrangement and relative position. In the present
case, these holders consist of a support block 40 which is
mounted directly on the turret plate 39 and serve to receive,
namely make contact with, the articles in question, in the
present case the sleeves 11. A radially outward-pointing
surface of the support block 40 is equipped with suction holes
41, which are connected by suction channels 42 to a central
source of suction. As can be seen from Figure 4, the angled
suction channels 42 of each support block 40lead to an annul-
ar channel 43 of a fixed facing plate 44 resting against the
turret plate 39. This facing plate is in turn fixedly mount-
ed on the main axle 18. The facing plate 44 at the same time
forms the lateral cover of the combi~ihg unit 10, on this side.
The holders 22 in each case comprise a side stop 45, rad-
ially movable relative to the support blocks 40, with two sup-
port arms 46 and 47. The movements are in each case trans-
mitted by a slide rod 48, which enters, by a sensor roll 49,
on an angled end, into a control slot 50 of the facing plate
44. This is so constructed that during the revolution of the
turret 20, the,side stops 45 move radially outwards or inwards.
The slide rods 48 are each guided in a guide member 51 of the
turret plate 39.
As a result of the mobility of the side stops 45, the
support arms 46, 47 can be completely retracted inwards (lower
part of Figure 3), so that the outward-facing surfaces of the
support block 40 are exposed and are able to receive articles.
Hence, it is possible to receive articles with tansverse dim-
ensions larger that the distance between the support arms 46,
47. This is the case, in the present instance, if the sleeves
11 are fed to the support blocks 40 in their flat compresses
shape and are picked by the said blocks. Only after the sleeve
11 has been erected to give a three-dimensional,
namely cuboid, shape, are the side stops 45 moved radially
outwards and now embrace, by means of the support arms 46, 47,
the article concerned, namely the sleeve 11, even at its sides.
The (immobile) side walls 24 of the pockets 21 of the
turret 19 are also mounted on the turret plate 39.
In order to facilitate the introduction of the slide
12 into the sleeve 11 which in each case faces it in the axial
direction, an introducing aid, which revolves with the sleeve,
is allotted to each of the sleeves 11. This aid consists of
four corner guides 52, which are pivotably mounted in the
region of the corners of the sleeve 11, on the entry side of
the sleeve. The pivot axles 53 for these corner guides 52 are
arranged diagonally so that the corner guides 52 can be pivoted,
from a retracted position, into the corners of the sleeve 11
(see Figures 9 and 10). The movement whereby the corner guides
52 enter the mouth of the sleeve 11 consists of a superposed
pivoting movement and axial movement. The former is executed
by the actual slide 12 which moves past the corner guides 52.
A movement, synchronous therewith, of the corner guides 52
in the axial direction into the sleeve 11 is effected by a
carrier 54, which in each case is ;connected to a guide rod
33, movable in the axial direction. The movement is control-
led by the fact that the carrier 54 enters, by a sensor roll
55 provided at the lower, that is to say radially inner, end,
into a corresponding control slot 56 on the outer periphery of
the control disc 32. The carrier 54 is furthermore slideably
mounted on the support rod 28 and is hence guided so that it
can exclusively execute axial movements.
The movements of the individual movable parts of the
12~2
combining unit 10 are effected by a common drive. This
consists, in the present case, of a drive wheel 57 mounted on
the main axle 18, to which wheel is connected a drive disc 58
which also revolves with it. The drive disc 58 is fixedly
connected, by the axially parallel support rods 28, to the
turret plate 39 which serves as the facing member. The guide
rods 33 are axially slideably mounted, by their ends r both in
the drive disc 58 and in the turret plate 39. The combining
unit 10, which executes a plurality of functions, is thus of
very compact and clearly set-out construction.
A particular application is the transfer, to a con-
tinuously revolving conveyor, that is to say to the turrets 19
or 20, of articles which are provided cyclically, that is to
say discontinuously. In the present case, the slides 12, pro-
vided with the cigarettes, are supplied by the conveyor 15,
constructed as a chain conveyor, and in fact are supplied
successively, each by a driver 59. The articles (slides 12)
are lifted by a lever 60 of the lifting apparatus 14 from the
conveyor 15 and are fed to the transfer apparatus 13.
The transfer apparatus 13 consists in the present
case of two groups of driver pockets 61. The construction of
these driver pockets 61 is such that upright pegs 63, that
is to say pegs pointing approximately in the radial direction,
are in each case located at the ends of mutually opposite stays
62. Two of these pegs 63 rest against opposite sides of the
articles, namely of the slides 12. The two stays 62 are con-
nected to one another by a cross-member 64. The latter, in
turn, is located at the end of a radial conveyor arm 65 or 66.
The carrier pockets 61 are accordingly open both radially and
--10--
~1~12~Z
at the sides.
A group of three conveyor arms, 65 on one side and
66 on the other side, connected to one another in a star
shape at equal angular spacings, forms one unit. The conveyor
arms, 65 on one side and 66 on the other side, are each separ
ately rotatably mounted on a shaft 69 by means of a hub 67 and
68 respectively. The conveyor arms 65, 66 and hence the driver
pockets 61 are driven at uneven peripheral speed, namely in
such a way that when receiving an article, that is to say in
the position adjacent to the lifting apparatus 14, the part-
icular conveyor arm 65, 66 stops momentarily. Thereafter, it
accelerates until it reaches the peripheral speed of the turret
19 or of the pockets thereof. The use of two mutually inde-
pendently movable, groups of driver pockets 61 ensures that
stopping, accelerating and momentarily running synchronously
with the turret 19 can take place in phases of motion which
follow each other in rapid succession, and hence with corres-
pondingly high productivity of the machine. During this
movement, the conveyor arms 65 or 66, with their driver pockets
61, successively enter the positions of acceptance and release
of an article. ~hilst, accordingly, one conveyor arm 65 is
brought to a stop, another conveyor arm 66 is accelerated to
the peripheral speed of the pockets 21.
A co~mon drive is allotted to the two groups of conveyor
arms 65 and 66. For this purpose, a two-arm drive member 70 is
fixedly mounted on the shaft 69. This drive member 70, re-
volving with the shaft 69, is provided, at each end, with a
bearing 71 for a drive peg 72. This axially parallel drive peg
72 is provided, on an arm 73, with a sensor roll 74, which
1~.412t3Z
engages in a control slot 75 of a control disc 76 which is
rotatably mounted on the shaft 69. As a result of the control
movements of the sensor roll 74, the drive peg 72 is caused
via the arm 73, to execute rotary movements during the revo-
lution of the drive member 70.
At the opposite end of the drive peg 72, a guide fork
77, which runs transversely, that is to say radially, is
attached. A driver roll 79, mounted on the conveyor arm 65
or 66, runs in the slit 78 of the fork.
Accordingly, a drive is transmitted to the conveyor
arms 65, 66 which is the resultant of, on the one hand, the
movement of the continuously revolving drive member 70 and,
on the other hand, of the movements of the drive peg 72
superposed thereon.
The driver pockets 61 are located at the ends of the
conveyor arms 65, 66 in such a way that for adjoining convey-
or arms 65, 66 these driver pockets 61 are in one plane. The
same is true of the driver rolls 79.
The articles, namely the slides 12, are moved along an
arc-shaped, fixed conveyor track 80 by the driver pockets 61.
The conveyor track 80 consists of two lateral angle-pieces
81, 82, each in the approximate shape of a quarter-circle arc.
The articles rest, with their ends, on the lower arms of
these angle-pieces 81, 82.
The conveyor track 80 leads directly to the combining
unit,10 and inparticular to its turret 19. The conveyor track
80 ends in the track in which the pockets 21 move. The angle-
pieces 81, 82 run on either side of these pockets 21 tsee Fig-
ure 8). As a result, the articles can be accepted by the poc-
kets21 without sideways movement. For such acceptance, the poc-
kets 21, or their side walls 24, 25, enter the zone between the
pegs 63 of the driver pockets 61.
The articles, namely the slides 12, are lifted by a
-
~14~282 ~
lifter 83 of the lifting apparatus 14 from the conveyor 15
and are introduced from below into the driver pocket 61, which
is open at the bottom, of the transfer appa.ratus 13. The
lifter 83 consists of a support surface 84, which is open on
the side facing the arriving articles, so that the articles
can be transported by the drivers 59 of the conveyor 15 onto
the lifter 83. On the opposite side, the articles are
supported against a stop 85~ which thereby determines the
precise relative position of the article on the lifter 83.
The lifter 83 is now pushed in an upwards parallel
direction, namely on an arc-shaped track which runs in the
direction of travel of the conveyor 15 and upwards. Accord-
ingly, the articles are taken off the conveyor 15 without an
abrupt change in the direction of travel, and hence gently.
The lifter 83 is mounted by an angle-piece 86 on
parallelogram guides 87 and 88. These, by pivoting to and
fro, provide the angularly upwards-directed parallel movement
of the lifter 83 or of the support surface 84. The drivers
59, which continue to run, ensure that the articles rest
against the stop 85 during this upward movement.
Since, in the zone of transfer of the articles to a
downward-pointing driver pocket 61, the angle-pieces 81 and
82 of the conveyor track 80 are constructed without the lower
arms, which act as a support for the articles, it is necessary,
in such a case, that after the introduction of the articles
into the driver pockets 61 some other support for the articles
should be provided until the articles have arrived in the
region of the arms 89 as a result of the further movement of
~14~
the driver pocket 61. For this purpose, holder bars 90, 91
which can be pivoted laterally against the article are
provided. These bars are provided on the sides facing the
articles, with a recess 92 which possesses a lower domed
support surface 93 for support- . . . . . . . . . . . . . .
-14-
1~12~2
ing the articles. The holder bars 90 and 91, and their
support surface 93, are so arranged, in the holding position,
that the support surfaces 93 form an extension or prolong-
ation of the arms 89 of the angle~pieces 81 and 82. Accord-
ingly, after having introduced the article into the driver
pocket 61, the lifter 83 can immediately return to the
starting position. By appropriate synchronous movement, the
holder bars 90 and 91 are laterally pivoted against the
artlcle, as a result of which the support surfaces 93
support the article from below. During the continued move-
ment of the driver pocket 61, which now commences, the art-
icle passes from the support surfaces 93 onto the adjoining
arms 89 of the conveyor track 80.
The holder bars 90, 91 are each mounted on double-
arm levers 94 and 95. Of these, the lever 95 is subjected
to a reciprocating motion by a slide rod 96. The movements
of the lever 95 are transmitted by an intermediate member
97, with a reversal of direction, to the angle-shaped lever
94.
A further slide rod 98 serves to drive the lifter 83
via a link plate 99. The levers 94 and 95, the parallelo-
gram guides 87, 88 and the link plate 99 are respectively
mounted on the same axles.
The apparatus is provided with a further device for
feeding articles into a turret of the combining unit 10.
This device is a rocker 16, which here serves to introduce
the laid-flat sleeves 11 into the turret 20. The rocker 16
is provided with a flat receiver 100 for receiving the
-15-
~J~41%t32
sleeves 11. The precise relative position of the sleeve 11
on this receiver 100 is determined by a stop 101.
The rocker 16 is arranged substantially tangentially
to the turret 20 (see, in particular, Figure 3). The move-
ment of the rocker 16 is such that the sleeve 11 is fed in
the radial direction to the turret 20 or is fed in the radial
direction to the support block 40 of a holder 22, with simul-
taneous movement in the direction of the revolving turret 20.
This superposed movement is achieved through the ends of the
rocker 16 respectively being connected to a rocker arm 102
and a crank 103. The movements are so selected that the
abovementioned motion is executed. In the position facing
away from the turret 20, the rocker 16 is charged with a
sleeve 11. The latter is transferred to the turret 20 by
resting against the support block 40, which, as a result of
the suction hole 41, immediately grasps the sleeve 11 and
carries it away.
As explained above, the sleeves 11 are introduced in
the lay-flat form into the turret 20. For combining the
sleeve 11 with the slide 12, the sleeve must be erected so as
to assume its final cuboid position. For this purpose, the
erector 17 is allotted to the turret 20 in the present illus-
trative embodiment. The erector is mounted coaxially with
the turret 20, namely rotatably mounted on one end of the
axle 104, as an extension of the main axle 18 (see Figure 4).
The erector 17 consists of a support plate 105
rotatably mounted on the end 104 of the axle. This plate is
caused to undergo a to-and-fro pivoting motion by means of a
2~
drive rod system 106. The latter engages in a swivel bear-
ing 107, on the support plate 105, at a distance from the
end 104 of the axle, that is to say at a distance from the
rotary bearing of the support plate 105.
The erector 17 is so constructed that two holders
22 of the turret 20, or two sleeves 11 contained in these
holders, are erected simultaneously. For this purpose, the
erector 17 is equipped with two conjointly driven lifing arms
108, 109. A suction head 110, 111 is located at the radially
outer end of each lifting arm 108, 109. This suction head
is brought up to the particular outer wall 112 of the sleeve
11 and gripped by suction. Accordingly, the sleeve 11 is
held by suction, on the one hand on the support block 40,
and on the other hand by the suction head 110 or 111~
The lifting arms 108, 109, and, together with these,
the suction heads 110, lil execute a semi-circular pivoting
movement corresponding to the process of erecting the sleeve
11. During this movement, the sleeve 11 is first brought
into the upright position and then "folded-back" beyond this.
Thereafter, the desired upright cuboid shape of the sleeve
11 is re-established.
To execute this movement, the lifting arms 108, 109
are connected to a shared drive by parallelogram plates 113,
114. This drive consists of a main wheel 115 (a gear wheel)
and auxiliary wheels 116 (also gear wheels) which enmesh
therewith. The parallelogram plates 113, 114 are each fix-
edly connected to such an auxiliary wheel 116.
The rotary movements of the main wheel 115 are trans-
-17-
~141Z82
mitted via the auxiliary wheels 116 to all parallelogram
plates 113, 114 and from these to the lifting arms 108, 109,
in the sense that the described movement of the suction
heads 110, 111 is executed. The suction heads 110, 111,
or the suction surfaces thereof which face the wall 112,
thereby execute a parallel movement.
The drive of the main wheel il5 is effected sepa-
rately, namely via a connecting rod 117, which is connected
to one end of a crankshaft 118. The opposite end of the
crankshaft 118 drives the main wheel 115 and, for this pur-
pose, is eccentrically hinged to a crank arm 119 of the main
wheel 115. The end of the crankshaft 118 which faces the
connecting rod 117 is joined to a connecting member 120
which in turn is carried by the pivot bearing 107.
The individual phases of the movement of the erector
17 are shown schematically in Figures 12 to 17.
Figure 12 shows the starting position, in which the
suction heads 110, 111 are brought up against the wall 112
of two sleeves 11 which are still in the lay-flat form.
The erector 17 now continues to travel for some distance
with the turret 20. During this movement, the lifting arms
108, 109 are moved in the manner described, as a result of
which the sleeve 11 is brought, from its initially flat
position, via a slanting intermediate position as shown in
Figure 13, into the cuboid position according to Figure 14.
However, the movements of the erector 17 go beyond the
position shown in Figure 14, namely via an (oppositely)
slanting position, as shown in Figure 15, as far as an
-18-
upper final position shown in Figure 16. In this, the
sleeve 11 is again pressed flat as in Figure 12, but in
the opposite direction. As a result, the sleeve 11 is
over-stretched in the region of the edges, or "folded-back".
If now the suction heads 110, 111 are released from the wll
112 of the sleeve 11 (Figure 17), the sleeve 11 assumes the
desired cuboid position by virtue of the strain in the mat-
erial. As the turret 20 continues to travel, the side stops
45 are moved into the radially outer position and now secure
the cuboid shape of the sleeve 11 by means of the support
arms 46, 47. The erector 17 reverts to the starting position
shown in Figure 12.
As a result of the simultaneous erection of the two
sleeves 11 it is possible to set the movements of the
erector 17 to suite the relatively high speed of revolution
of the turret 20. The turret 20 has moved on by an amount
corresponding to two holders 22 when the erector 17 reverts
to the starting position ater one cycle.
In Figure 12, the hatched arc-shaped strips represent
the phases of the movement of the combining unit 10. The
segment 121 represents a zone of about 40, in which the
radial movement of the side stop 45 takes place. The segment
122 - about 20 - corresponds to the corner guides 52 being
brought into the working position in relation to the sleeve
11. Finally, the segment 123 outlines the process of pushing
the slide 12 into the sleeve 11.
At the end of the segment 123 is located an ejector
124, by means of which the finished packages are expelled

from the holders 22 and charged onto a packaging conveyor
125. In thP present case, the ejector 124 is mounted on the
same axle 126 as the rocker arm 102 for the rocker 16.
This results in a simple construction of the apparatus.
