Method and apparatus for manufacturing clamshell box packs for cigarettes

technical field

The invention relates to a method for producing a clamshell box pack of cigarettes, the pack having a box part and a cover pivotally supported on the box part, wherein the blank of the pack is folded in a folding device, in particular a folding turret Folding to the finished package as far as possible with the formation of packaging walls delimited from each other by folding lines, wherein the side panels of the blank protrude laterally relative to the packaging in order to form the side walls of the packaging and are subsequently processed in a gluing station Glue is supplied and then joined with the other side panels of the blank to form the side walls of the package. Furthermore, the invention relates to a corresponding device.

Background technique

The problem with producing flip-top box packs according to the method described above is to maintain the correct relative position of parts of the pack or pack walls with respect to each other, especially during gluing of the side walls and during the continuation of the conveying and folding process. Even though devices are known in practice which are responsible for orienting the lid, that fact also shows that it is not always possible to produce properly formed packages.

Contents of the invention

Proceeding from this, the object of the invention is to further develop a method and a device of the type mentioned at the outset.

To achieve this, it is provided that, preferably in the region of the gluing station, parts of the packaging or of the packaging walls are aligned with one another in a defined relative position, and that the relative position achieved thereby is guided by a guide, in particular an upper guide The top and lower guides are retained during transport of the package along a cardboard track.

The advantage of the method according to the invention is that the orientation achieved once remains unchanged during the further conveying and folding process, so that the correct relative position of the parts of the package or of the package walls remains unchanged in order to form a correctly configured package.

Preferably, the orientation is carried out in such a way that the parts of the packaging or of the packaging walls to be oriented are arranged on mutually different planes, after which the parts of the packaging or of the packaging walls to be oriented to each other are moved away from each other, in particular by erecting elements And then it is preferably moved to a common plane or held there by the pressing device.

According to a preferred embodiment of the invention, it is provided that the cover of the package is opened in the region of the gluing station by means of the upstanding elements and closed in the correct relative position by means of corresponding supports, whereby the laterally protruding side panels are connected between the cover and the box. and the glue is applied to said oriented side panels and the side panels are held in this thus achieved relative position to each other during transport by means of guides. Preferably, the lid is opened by means of the vertical element by engaging and lifting the lid closure edge of the lid from below.

Another feature, which is both an extension of the invention mentioned at the outset, but also an independent solution, provides that the glued side panels are held under pretension, preferably under pretension, during connection with other side panels of the blank to form the side walls. In particular, the bottom is folded onto the plane of the side wall in such a way that the free edge of the glued side wall bears against the guide during the folding process. This solution has in particular the advantage that the freshly applied glue is not thrown off when closing the side panels, but adheres to them.

A corresponding feature of the device according to the invention is that, preferably in the region of the gluing station, parts of the packaging or of the packaging walls can be oriented relative to each other; and a guide mechanism is provided for transporting the packaging along the transport track The resulting relative position is ensured.

Another feature of the device may be that guides are provided laterally on the transport track, in which the side panels are held under tension, so that the relative position of the parts or side panels after orientation of the package continues to be conveyed Remains unchanged during packaging.

The side panels under tension can be guided in such a way that the side panels are held between upper and lower guides arranged laterally to the transport rail of the package, wherein the upper guide and the lower guide Each side of each is disposed at a different lateral spacing relative to each other or a different lateral spacing relative to a side wall of the package. Due to the lateral spacing of the upper and lower guides in the horizontal plane of the packaging sides, forces are introduced into the side panels in planes that are laterally offset from one another, so that the side panels or the corresponding packaging surface remain in an aligned position.

Furthermore, a receptacle with lateral guides for the packaging is provided behind the transport track, in which receptacle the side panels are likewise held pretensioned, wherein, when the side panels abut progressively against the side wall of the packaging Next, the package is conveyed out of the receptacle in a preferably upright direction; and, during the movement of the package relative to the guide, the free edges of the side panels rest against or are guided along the wall of the guide.

Preferably, the corresponding bracket is also designed for closing a cover that is opened too far beyond the desired position.

Detailed ways

The embodiment of the invention shown in the figures is used to make a pack 10 of cigarettes. The package 10 corresponds in its structure to the usual structure of clamshell box packs or hinge-lid packs. Accordingly, the package 10 has a box part 11 and a cover 12 pivotably supported on the box part 11 . The side walls of the packaging, namely the box side wall 13 and the lid side wall 14 , are formed by the joining of two side panels in each case, ie the respective inner and outer box side panel 15 and lid side panel 16 .

The packaging 10 is produced by correspondingly folding a blank made of a suitable packaging material, for example cardboard. For this purpose the blank has a folding line 17 about which the blank is folded. The fold lines 17 partially form corresponding edges of the later formed package 10 .

The blank is first folded on a conventional packaging machine 18 . For this purpose, the blanks are generally on standby in a magazine and folded as far as possible into finished packages 10 in suitable folding devices, preferably in folding turrets (not shown). In general, the blank leaves the folding turret as a package 10 as close as possible to the finished product according to FIG. 2 with the outer box side flap 15 and lid side flap 16 unfolded. It can be seen that the outer box side panel 15 and lid side panel 16 lie in the plane of the front of the package 10 . The inner box side panel 15 and lid side panel 16 have been folded onto the plane of the later formed box side wall 13 and lid side wall 14 .

In the aforementioned arrangement, the package 10, folded as completely as possible, is transported along so-called cardboard rails 19 as transport rails and to the gluing station 20, in which the outer box side panels 15 and lid side panels 16 are Glue 40 is supplied. Thereafter, the outer box side panel 15 and lid side panel 16 are folded towards the inner box side panel 15 and lid side panel 16 , thereby completing the folding of the package 10 .

In the present exemplary embodiment, the cardboard track 19 is designed as a double track, so that two packages 10 are processed on two tracks parallel to each other. As an alternative, it is conceivable that the gluing station 20 and the cardboard track 19 are designed as a single track or are constructed with a greater number of tracks.

The application of glue 40 to the inner side of the outer box side panels 15 and lid side panels 16 takes place by means of a glue disc 21 which has glue 40 on its circumference and rests against the underside of the side panels 15 , 16 . The pressure plate 22 is arranged relative to the upper glue plate 21 in such a way that the side panels 15 , 16 are pressed against the upper glue plate 21 from above by the pressure plate 22 as a pressing device. Each cardboard track 19 has a respective pair of upper glue discs 21 and a respective pair of pressure discs 22 .

The upper glue discs 21 are arranged on a common shaft 23 . The pressure plates 22 are likewise arranged on a common shaft 24 . For driving, the shafts 23 , 24 have a common drive (not shown) that drives the shafts 23 , 24 in succession. The drives are controlled as usual by a control unit in conjunction with the machine control system.

In the region of the cardboard track 19 the packs 10 are transported lying on the conveyor along the cardboard track. The conveying mechanism is the upper return section of the belt conveyor 25 in this case. In this case, the rear side of the packaging 10 is gripped by a radially protruding carrier 26 arranged on a belt conveyor 25 .

The first feature relates to the orientation of the lid 12 with the laterally projecting lid side panels 16 as shown in FIG. 2 . An incorrectly oriented cover 12 is shown here with dashed lines. The solid line shows the prescribed (correct) position of the cover 12 or of the cover side panels 16 . In order to orient the possibly movable cover 12 relative to the box part 11 before gluing the side panels 15 , 16 , special upstanding elements 27 are featured.

In the present case, erecting elements 27 are arranged in the region of the gluing station 20 . However, an arrangement upstream of the gluing station 20 is also conceivable.

The erecting elements 27 serve to orient parts of the blank, in this case the lid 12 . As can be seen from FIGS. 8 - 10 , the erecting element 27 grips the cover 12 during transport in the region of the gluing station 20 , wherein the cover 12 is pivoted slightly in the direction of the open position. Thereafter, the side flaps 16 of the cover 12 are moved by the pressure plate 22 onto the plane of the front of the package and the cover 12 is closed by the corresponding bracket 28 whereby the parts to be oriented of the package 10 are brought into the correct relative position.

A vertical element 27 is arranged above each cardboard rail 19 and grips, in the region of the free end 29 , the rear closed edge of the cover 12 in the conveying direction. Due to the higher movement speed of the erecting element 27 compared to the continuous conveying speed of the package 10 , the cover 12 is thus opened slightly until the package 10 enters the operating area of the counter support 28 which then closes the cover 12 in a controlled manner.

The vertical element 27 is designed in this case as a hook element which is rotatably mounted on an axle 30 above the cardboard rail 19 . Each vertical element 27 here has two free ends 29 which are toothed and engage behind the closing edge of the cover 12 . Each cardboard track 19 has an upstanding element 27 .

The shaft 30 is hingedly connected to a link 32 via a pivot lever 31 . The connecting rod 32 is in turn articulated to a crankshaft 33 arranged on the shaft 24 of the pressure plate 22 . In this way, the two shafts 24 and 30 are coupled to each other.

The counter-carriage 28 is arranged on the shaft 24 between the vertical element 27 and the pressure plate 22 always concomitantly rotating. The respective directions of rotation are taken from the marked parts in the figures. In the present case, a corresponding bracket 28 is arranged on each side of the erecting element 27 .

Through the previously described coupling of the shaft 30 to the shaft 24, the erection element 27 is not driven in a circular rotation, but is driven in a back and forth rotation, so that after the packaging 10 leaves the gluing station 20, the erection element 27 The cover 12 is moved back in order to enter the position for opening the cover 12 of the next package 10 .

Another special feature of the device is the arrangement or structure of the guides of the laterally protruding box side panels 15 and lid side panels 16 of the packaging 10 in the region of the cardboard rails 19 . To this end, an upper guide 34 and a lower guide 35 are arranged on each side of the packaging 10 in the region of the cardboard rail 19 . In this way, the side panels 15 , 16 are held between the upper guide 34 and the lower guide 35 .

In the area of the gluing station 20 or in the operating area of the erecting element 27 , it is provided as a feature that the upper guide 34 and the lower guide 35 have a slightly greater distance 36 from one another in the erecting direction. The greater distance 36 between the two guide rails 34 , 35 makes it possible for the cover 12 to spring up due to the restoring force caused by the material, so that the cover 12 is gripped by the erecting element 27 and can be opened.

During the further transport of the package 10 in the cardboard rail 19, the guide mechanism ensures that the oriented parts of the package 10 remain in their oriented position.

In other words, it is ensured that the orientation taken by the side panels 15 , 16 or the cover 12 by the erecting elements 27 and the corresponding supports 28 remains unchanged during onward transport.

FIG. 7 shows another feature of the corresponding bracket 28 . If the lid 12 is opened too far by the vertical element 27 or otherwise, the counter support 28 is structured accordingly, so that the lid 12 is closed as intended, while at the same time the parts of the packaging are oriented.

FIG. 12 shows a vertical cross-sectional view of the cardboard rail 19 . It can be seen here that in this way the side panels 15 , 16 are held between the upper guide 34 and the lower guide 35 . A special feature here is that the upper guide 34 and the lower guide 35 are arranged in such a way that the side panels 15 , 16 are held under tension during transport of the package 10 along the cardboard track 19 .

In this embodiment, the upper guide part 34 and the lower guide part 35 are respectively arranged laterally offset from each other on both sides of the cardboard rail 19 . For example, as shown in FIG. 12 , the upper guide 34 is always arranged laterally closer to the package 10 than the lower guide 35 is positioned laterally further away. On the vertical plane, the upper guide part 34 and the lower guide part 35 can be basically arranged on the same plane, but wherein each top surface of the lower guide part 35 is arranged slightly lower than each bottom surface of the upper guide part 34 . Due to the lateral spacing of the upper guides 34 and lower guides 35 on each side of the packaging 10 , the side panels 15 , 16 are deflected under tension and deform in an arcuate shape in cross-section. This prevents the side panels 15, 16 or cover 12 from being able to move relative to each other after orientation.

It goes without saying that the arrangement of the upper guide portion 34 and the lower guide portion 35 can be selected differently, as long as the side panels 15, 16 can be kept under tension.

Further components of the guide mechanism may be side guides 37 arranged laterally to the cardboard rail 19 which are arranged laterally to the side walls 13 , 14 of the packaging. The side guides 37 also serve to hold the inner side panels 15 , 16 , which have been folded at this point in time, in the plane of the side walls 13 , 14 .

After the cardboard track 19 the package 10 enters the receptacle 38 of the package 10 which is partially folded and glued. The or each receptacle 38 is laterally provided with guides for the side panels 15 , 16 similarly to the cardboard rails 19 . In this case, the guides are designed as in the region of the cardboard rail 19 so that the side panels 15 , 16 are held under tension.

The packages 10 are transferred upwards via a package elevator 39 to a transfer turret not shown. Here, the package 10 is conveyed upwards out of the receptacle 38 by means of a package elevator 39 , wherein the side panels 15 , 16 are moved onto the plane of the side walls 13 , 14 in order to align the inner side panels 15 , 16 with the outer side panels. 15 , 16 connect and thus complete the folding of package 10 .

As can be seen from FIG. 13 , the cross section of the upper guide 34 is curved, so that the side panels 15 , 16 rest on the underside of the curved region. During lifting of the package 10 , the side panels 15 , 16 are accordingly guided along the rounded areas and moved onto the plane of the side walls 13 , 14 . In this case, the side panels 15 , 16 are kept under pretension due to a corresponding configuration of the lower guides 35 , so that excessively fast feed movements prevent already applied glue 40 from being thrown out of the side panels 15 , 16 .

In the present case, the cross-section of the lower guide 35 is arc-shaped, so that the free edges of the side panels 15 , 16 slide along the arc-shaped contour of the lower guide 35 . In this way, the pretension of the side panels 15, 16 can be maintained.

FIG. 14 shows the package 10 partially lifted just before the side panels 15 , 16 rest on the inner side panels 15 , 16 on the plane of the side walls 13 , 14 .
