This application accompanies the priority claim to Italian Patent Application No. 102020000022189 filed on September 21, 2020, which is incorporated herein by reference.

[Technical field]

The present invention relates to a manufacturing method and machine for manufacturing a rigid pack of smoking articles.

The present invention can be advantageously applied in a packing machine for manufacturing cigarette packs known as "wallets", which will be described below, but the present invention is not limited thereto.

A “wallet” pack of cigarettes includes two inner containers, each containing a group of wrapped cigarettes, each having a separate open top end, hinged together by an outer container to close it. It is rotatable between a configuration and an open configuration, wherein in the closed configuration the two inner containers overlap one another and in the open configuration the two inner containers are separated. Also provided is a lid hinged to the outer container, which in the closed position encloses the upper portions of both inner containers.

In the production of "wallet" packs of cigarettes, two inner containers are formed using two corresponding blanks folded around each of the groups of wrapped cigarettes, the two inner containers (overlapping) ) combining, and folding a third blank around the two (overlapping) joined inner containers to connect the two inner containers and form an outer container provided with a common lid.

To simplify the manufacture of the outer container, one wall (e.g. bottom wall) of the outer container can be glued to the two inner containers, thus preventing separation of the two inner containers after folding of the third blank. It may be necessary to make a cut in the bottom wall of the outer container to allow (ie to allow rotation of the two inner containers relative to each other).

It is known to use a single rotating blade to cut the bottom wall of an outer container in two to separate the two inner containers. However, it has been observed that during the cutting operation by this, the blade is contaminated due to the adhesive located on the bottom walls of the inner containers and the outer container, and thus it is necessary to stop the manufacturing machine frequently to remove the adhesive. .

In order to solve the above problem, a method of preventing adhesive from being located on the bottom wall of the outer container in the separation area (ie, the cutting area) between the two inner containers has been proposed. However, in the case of this solution, on the one hand, it is very difficult to control the movement of the adhesive when it is pressed between the inner containers and the bottom wall of the outer container (i.e., when the adhesive is pressed, the adhesive “intrudes” into the cutting area). "can), on the other hand, in this solution there is no adhesive at the edge of the bottom wall of the outer container, and the phenomenon of free "fluttering" at the edge (which is not held in the desired position by the adhesive) tend to occur, giving the end user the impression that the cigarette pack is of poor quality.

Also, to remove the strap (strip) from the outer container's outer container bottom wall in the separation area between the two inner containers to create a clear separation between the two inner containers. A double cut (i.e., two closed parallel cuts) may be performed. In this case, however, a cutting unit with two parallel and adjacent rotating blades must be used, which blades must be partially accommodated in a collecting chamber, where the strap is separated from the rest of the bottom wall. An adsorption action is performed which must be removed and captured.

However, there is often a problem that the strap remains caught on the bottom wall after cutting performed by the two rotary blades and is not provided by suction. Thus, some “wallet” packs of cigarettes downstream of the cutting unit have a strap remaining on the bottom wall of the outer container, the location of which is unclear. This causes various problems, for example a clear plastic outer wrap or packaging (including a clear plastic outer wrap) for the strap with a pack of cigarettes with the strap in a completely random position due to loss of the strap from the machine. This may give the end user the impression that the cigarette pack is of poor quality.

In addition, even after cutting by the two rotary blades, the strap may be caught between the two rotary blades, which may cause the jamming phenomenon and may cause the packing machine to stop for a long time.

Patent document WO 2005/054056 A1 discloses a manufacturing machine configured to manufacture cigarette "wallet" packs, which machine is connected to a first inner frame and also forms a first group of wrapped cigarettes; a second machine connected to the second inner frame and forming a second droop of wrapped cigarettes, and a third machine combining the two groups of wrapped cigarettes into a single hinged pack with vertical hinges.

In the packaging unit disclosed in patent document WO 2016/166692 A1, a method of subjecting a tape of packaging material to a process of removing the material by means of a laser is disclosed.

Patent document EP 2253547 A1 discloses a rigid pack of cigarettes containing two distinct groups of cigarette packs and having a hinged lid.

Reference numeral 1 in FIGS. 1 and 2 denotes the entire rigid pack of cigarettes of the “wallet” type, said rigid pack comprising two inner containers 2 (shown separately in FIGS. 5 and 6 ). and the inner containers 2 contain groups 3 of individually wrapped cigarettes (shown in Figs. 3 and 4). Specifically, FIG. 3 shows a group 3 of unwrapped (i.e., unwrapped) cigarettes, and FIG. 4 shows a group of wrapped (i.e., provided with soft wrapping with an upper tear) (3) is shown.

In the illustrated non-limiting embodiment, the two groups of cigarettes 3 (and thus the two inner containers 2) are of different sizes, i.e. one group of cigarettes 3 corresponds to another inner container 2 ) is greater than

As shown in Figs. 1 and 2, a cigarette pack 1 includes an outer container 4, and the outer container 4 encloses two inner containers 2 therein, and also includes two inner containers (2) are equipped with a hinge that allows them to rotate between a closed configuration (shown in FIG. 1) and an open configuration (shown in FIG. 2). In the closed configuration, the two inner containers 2 are superimposed on each other, and in the open configuration, the two inner containers 2 are separated. In addition, the outer container 4 is provided with a lid 5 hinged to the outer container 4, which encloses the upper parts of both inner containers 2 in the closed position (shown in FIG. 1). .

The production of a pack of cigarettes 1 initially forms a group 3 of two cigarettes, wrapping individual wrapping around the group 3 of cigarettes, and folding around the group 3 of individual cigarettes ( and manufacturing the two inner containers 2 using two corresponding blanks (as known, not separately shown) stabilized by an adhesive. After the group 3 of cigarettes is formed, the two inner containers 2 (which contain the group 3 of individually wrapped cigarettes) are joined together (overlapping), and then (shown in FIG. 7 The outer container 4 is made by folding (and stabilizing with adhesive) a blank 6 (which has been formed) around the two inner containers 2 joined together.

1 and 2 immediately after folding of the blank 6, the outer container 4 has a bottom wall 7 and a side wall 7, the bottom wall 7 having two inner Glued to both containers 2 (thus not allowing the inner containers 2 to rotate relative to each other), the side wall 7 is glued to the two inner containers 2 (thus the inner container 2 are not allowed to rotate relative to each other). Therefore, in order to enable the separation of the two inner containers 2 (ie, to enable the two inner containers 2 to rotate relative to each other), the side wall 7 and the bottom wall of the outer container 4 ( 7) Need to perform cutting on both. During folding of the blanks 6 to form the outer container 4, the walls 7 (which are part of the blank 6 and thus of the outer container 4) are formed (individual inner container 2). It should be noted that all of the groups 3 of the wrapped smoking article are seated (with ).

In FIG. 8 , reference numeral 8 denotes the entire cutting unit, wherein already fully formed cigarette packs 1 carry out cutting on the walls 7 of the outer container 4 of each cigarette pack 1 . (For simplicity, only the cutting of the bottom wall 7 is shown in FIG. 8, but the cutting of the side wall 7 is carried out in the same manner).

Specifically, as shown in FIG. 9 , the cutting unit 8 has a double primary piercing cut (i.e., two primary halves parallel and spaced apart from each other), in order to create a clear separation between the two inner containers 2. through-cutting portion 9) to remove the strap 10 (strip) of each wall 7, the cutting unit 8 correspondingly relatively from each wall 7 of the cigarette pack 1 Separate the two inner containers (2) by removing the thin central part (strap (10)).

In the embodiment shown in the attached figures, the two primary through-cuts 9 separating the strap 10 from the rest of each wall 7 are parallel to each other, so that the strap 10 has a constant width. have In other embodiments not shown, the two primary through-cuts 9 separating the strap 10 from the rest of the respective wall 7 may not be perfectly parallel to each other (i.e. they may be relative to each other). may converge or diverge slightly), and thus the strap 10 may have a variable width.

As shown in FIG. 8 , the cutting unit 8 comprises a conveyor which continuously feeds cigarette packs 1 along a straight path P, said conveyor being described in patent documents EP 1916188 A1 and EP 2172399 for example. It may be manufactured as disclosed in A1. In addition, the cutting unit 8 includes (at least one) an emitter 11, which sublimates (vaporizes) a portion of the packaging material constituting the blank 6, thereby causing the primary through-cutting portion 9 ), it is configured to focus the laser beam on each wall 7 of each blank 6 (or of the corresponding outer container 4 formed by the blank 6). In other words, in each of the cigarette packs 1 supplied along the path P, primary through-cuts 9 separating the strap 10 from the rest of the respective wall 7 are made by means of a laser beam, The laser beam is irradiated to the wall 7 of the outer container 4 (or the wall 7 of the blank 6 forming the outer container 4) to sublimate (vaporize) a portion of the packaging material.

For example, a laser spot is irradiated on each wall 7 and moved by using mirrors automated by galvanometers (and a laser marker and a 2-axis scanning head), but with an additional automatic device acting on the laser irradiation (laser spot). markers and three or more axis scanning heads) may be present. Generally, during the formation of the primary through-cuts 9 by the ejector 11, the cigarette pack 1 may or may not move. The position of the cigarette pack 1 during any movement can be tracked by a position sensor or visual optical system connected to the conveyor device.

The primary through-cuts 9 formed by the emitter 11 can be straight or along a freely programmable trajectory.

As explained above, in each cigarette pack 1 and in each wall 7, two spaced apart primary through-cuts 9 define a waste part of the wall, the strap 10, ie it It is the part that must be separated and removed from the rest of the wall (7). As shown in FIG. 9 , in order to simplify the separation and removal of the straps 10 (which form the discarded part of each wall 7), there are two primary through-cuts 9 as well as a series of secondary It is also possible to make the through-cutting portion 12 by the cutting unit 8, and the secondary through-cutting portions 12 divide the strap 10 into a plurality of small parts 13 to cut the strap 10 into each wall ( 7) to facilitate separation and removal. Specifically, each secondary through-cutting portion 12 is formed in a direction transverse to the two primary through-cutting portions 9 (perpendicularly or otherwise inclined), and the two primary through-cutting portions 9 ) to each other (thereby dividing the waste part into two parts 13). In the embodiment shown in FIG. 9, various secondary through-cutting portions 12 are formed to divide the strap 10 into various parts 13, but in other embodiments not shown, the strap 10 is formed in only two parts. A single secondary piercing cut 12 may be made to divide the dog into parts 13 .

In the preferred embodiment shown in Fig. 8, the cutting unit 8 comprises a suction device 14 arranged in a cutting station, in which the wall 7 of each pack of cigarettes 1 is irradiated with a laser beam; From the walls 7 the waste part (ie the strap 10 or the plurality of parts 13 from which the strap 10 is divided) is sucked.

In addition, the cutting unit 8 also includes an adsorption system for adsorbing smoke (dust) formed after sublimation (vaporization) of the packaging material constituting each wall 7 . According to a possible embodiment, the adsorption device 14 can adsorb both the waste part and the smoke (dust), downstream of the adsorption device 14 being freed from the smoke (dust) by suitable filters for different treatments. Material may separate.

In the embodiment shown in the attached figures, the cutting unit 8 performs cutting on two different walls 7 of each pack 1 of cigarettes (ie bottom wall 7 and side wall 7). do. In another fully equivalent embodiment, the blanks 6 are made to have different shapes, and the cutting unit 8 is only for a single wall 7 of each cigarette pack 1 (ie bottom wall 7 or side wall). (7) only one) to perform cutting.

Summarizing the foregoing, a group of two cigarettes 3 is formed in each cigarette pack 1 in the forming unit, and two inner containers ( 2) is formed, in the second packaging unit, the blank 6 is folded around the two inner containers 2 (i.e. around the group 3 of two cigarettes) to form the outer container 4 and at this stage (at least) the bottom wall 7 of the outer container 4 is glued to both inner containers 2 . Finally, in the cutting unit 8, two primary through-cuts (at least) spaced apart from each other in the bottom wall 7 of the outer container 4 and extending between two opposite ends of the bottom wall 7 ( 9) is made, and the first part of the wall 7 glued to the inner container 2 is separated from the second part of the wall 7 glued to the inner container 2.

The cutting unit 8 can be used to perform further processing on each cigarette pack 1, in addition to the formation of the primary through-cut 9 (and possibly the secondary through-cut 12 as well). . For example, the laser emitted by the emitter 11 (in addition to the formation of the first through-cuts 9 and possibly the second through-cuts 12 ) is directed to the wall of the outer container 4 as a vector. ) or to create raster alphanumerical markings, bar codes, logos, or pictures and decorative elements. In general, the operating parameters of the emitter 11 (power, speed, frequency, number of repetitions, diameter, and spot focus) may differ from process to process, and the operating parameters of the emitter 11 may change during the same process. there is.

In the embodiment shown in FIGS. 1 to 9 and 11 , the cutting unit 8 makes two primary piercing cuts 9 spaced apart from each other in each cigarette pack 1 , said two primary piercing cuts 9 Cuts 9 extend between the two opposite ends of the wall 7 , thereby separating and removing the strap 10 (ie the waste part) from each wall 7 .

In another embodiment shown in FIG. 12 , the cutting unit 8 makes a single primary through-cut 9 extending between two opposite ends of each wall 7 in each cigarette pack 1 . . In this embodiment, in either case, each wall 7 is divided into two parts (each part is glued only to the corresponding inner container 2), but no waste part is formed (straps from the wall 7). (10) is not removed).

In a further embodiment shown in FIG. 13 , the cutting unit 8 is arranged adjacent to and in contact with each other on each wall 7 in each cigarette pack 1 (i.e. between two adjacent primary through-cutting portions 9). no packaging material remains) to make at least two first through-cuts 9, whereby the wall 7 is widely separated (ie the wall 7 is in any case divided into two parts), but no waste part is not formed (the strap 10 is not removed from the wall 7). In other words, in the embodiment shown in FIG. 13, the strap 10 (which is a discarded part) is formed by a plurality of closed paths (strokes) of the laser, that is, a plurality of primary through-cut portions 9 adjacent to and in contact with each other. is completely "disintegrated" (sublimation, vaporization) by means of which no packaging material (ie waste material to be mechanically removed) remains between the primary through-cutting portions 9 .

Comparing FIGS. 10 and 11, the double primary through-cutting portion 9 (FIG. 10) mechanically performed by a rotating rotary blade and the double primary through-cutting portion 9 (FIG. 11) formed by a laser are confirmed. It will be. The primary through-cut (9) formed by the laser provides excellent separation (and possibly even the adhesive intervening between the wall (7) and the underlying inner container (2)) Separation or vaporization of a portion of the adhesive interposed between the containers 2) while preventing contamination of the blades by the adhesive interposed between the wall 7 and the inner containers 2 placed below. The mechanically formed primary through-cut (9) should be very thin (and therefore uncertain) close to the adhesive. As a result, the strap 10 formed by the double primary through-cuts 9 formed by the laser ( FIG. 11 ) leaves no residue of any kind in relation to the wall 7 and can thus be removed very easily. On the other hand, the strap 10 formed by the double primary through-cuts 9 mechanically formed by the double rotating blades ( FIG. 10 ) is more difficult to remove since residues associated with the wall 7 may occur ( and difficult to remove without the rotating blade becoming contaminated with adhesive).

In the different embodiments shown in FIGS. 14 and 15 a single group 3 of wrapped cigarettes is obtained, which cigarettes are inserted into a single inner container 2 which is slidably accommodated inside an outer container 4 . (the blank 6 is folded around the single inner container 2 and therefore is in the outer container 4), and the single primary through-cutting portion 9 is of a structure closed to itself, and the outer container 4 Separate the button 16 attached to the inner container 2 placed below from the side wall 15 of the ). In this embodiment, the primary through-cut 9 may also be discontinuous (residual connection points may remain, which must be broken upon first opening of the pack 1 to ensure integrity). Also in this embodiment, one blank 6 produced by the primary through-cutting portion 9 makes the opening of the cigarette pack 1 more “complicated” (i.e. from the outer container 4 to the inner container 2). slide and withdraw), which is for "child protection" in relation to the opening of the cigarette pack (1).

In the various embodiments shown in FIGS. 16-19 a single group 3 of cigarettes is provided, which is inserted directly into the outer container 4 (i.e. the blank 6 is placed around the group 3 of cigarettes). is directly wrapped around the inner container (2) is not present), the outer container (4) is provided with a sliding lead (5), and a single primary through-cut portion (9) is provided on the rear wall of the outer container (4) ( 17) to allow complete separation between the outer container 4 and the sliding lid 5, allowing the lid 5 to slide relative to the outer container 4 (i.e. initially sliding lid 5 ) is connected to the rest of the outer container (4) at the rear wall (17) and completely separated from the rest of the outer container (4) only by the primary through-cut (9). In this embodiment, the primary through-cut 9 may also be discontinuous (residual connection points may be left that must be broken upon first opening of the pack 1 to ensure defect-freeness). Also in this embodiment, the primary through-cutting portion 9 is straight (as shown in Figs. 16 and 17) or zigzag with sharp or rounded edges (as shown in Figs. 18 and 19). can have the shape of

Obviously, even in the embodiments shown in FIGS. 14 to 19 , it is possible to make two primary through-cuts 9 placed next to each other in the wall 15 , 17 , whereby the corresponding wall 15 , 17 ) It is possible to separate and remove the strap 10 from.

Embodiments disclosed herein may be combined with each other without departing from the scope of the claims of the present application.

The manufacturing method described above has many advantages.

Firstly, the manufacturing method described above enables the cigarette pack 1 to be manufactured in an efficient and effective manner and enables the use of the blank 6, wherein certain cutting operations of the blank 6 After completion of folding (or during folding of the blank 6), manufacturing and folding of the blank can be made simply and quickly.

In addition, due to the manufacturing method described above, the formation of the primary through-cutting portions 9 can be performed without risk of errors and contamination (and thus without periodic cleaning), even if adhesive is present beneath the primary through-cutting portions 9 . It can be done with extreme precision.

If necessary, the manufacturing method described above makes it possible to remove any strap 10 in a convenient and safe manner (i.e., without discarding parts) after cutting the strap 10 (or a piece of strap 10). Downstream of this cutting unit 8 it can be prevented from remaining in contact with the bottom wall 7 .

Finally, the manufacturing method described above is simple and inexpensive to implement compared to similar manufacturing methods known in the art, and can be obtained quickly and quickly using commercially available tools (e.g., emitters 11) or materials that can be easily obtained in standard mechanical processes. Process variations are possible.

Although the present invention has been described with reference to the manufacture of packs of cigarettes as shown in the embodiments shown in the accompanying drawings, the present invention is not intended for packs of other types of smoking articles (e.g. packs of cigars, liquid vapor type electronic packs of cigarettes, packs of next-generation smokeless cigarettes, etc.) can also be applied without substantial change.
