[0002] This patent application claims priority to Italian Patent Application No. 102020000022189, filed on September 21, 2020, the entire disclosure of which is incorporated herein by reference. Technical Field
[0003] The present invention relates to a method and a machine for manufacturing a rigid packaging box for a suction article.
[0004] The present invention finds an advantageous application in a packaging machine for manufacturing cigarette packaging boxes (also known as "wallet" cigarette packaging boxes), which will be clearly described in the following disclosure without losing generality thereby. Background Art
[0005] A "wallet" cigarette packaging box includes (at least) two internal receiving portions that receive corresponding packages of cigarette groups, have corresponding open upper ends, and are hinged to each other by an external receiving portion to rotate between a closed configuration in which the two internal receiving portions are stacked on top of each other and an open configuration in which the two internal receiving portions are separated; in addition, a lid is provided, which is hinged to the external receiving portion and encloses the upper portions of the two internal receiving portions when in the closed position.
[0006] The production of a "wallet" cigarette packaging box is set up to form two internal receiving portions by folding two corresponding blanks around corresponding packages of cigarette groups, joining (stacking) the two internal receiving portions, and then folding a third blank around the two joined (stacked) internal receiving portions, which will connect the two internal receiving portions and create an external receiving portion provided with a common lid.
[0007] To simplify the manufacture of the external receiving portion, one wall (e.g., the bottom wall) of the external receiving portion can be glued to the two internal receiving portions, and thus, after folding the third blank, it may be necessary to form a cut in the bottom wall of the external receiving portion to allow the two internal receiving portions to separate (i.e., to allow the two internal receiving portions to rotate relative to each other).
[0008] It is known to use a single rotary blade to cut the bottom wall of the external receiving portion in half to separate the two internal receiving portions; however, it has been observed that during the process of performing this cut, the blade tends to be soiled by the glue applied between the bottom wall of the external receiving portion and the internal receiving portion, and thus, the rotary blade requires the manufacturing machine to be frequently stopped to remove the glue.
[0009] To solve this problem, it has been proposed not to apply glue at the separation area between the two internal receiving parts (i.e., at the cutting area) on the bottom wall of the external receiving part; however, on the one hand, this solution is difficult to implement because it is difficult to control the movement of the glue when the glue is squeezed between the bottom wall of the receiving part and the internal receiving part (i.e., the glue moves randomly when squeezed and may "invade" the cutting area in any case), and on the other hand, it leaves the edge of the bottom wall of the external receiving part without glue at the incision, and thus this edge (not held in the required position by the glue) tends to move freely, giving the end user the impression of a poor-quality cigarette packaging box.
[0010] It is also possible to perform a double cut (i.e., two close and parallel incisions) at the separation area between the two internal receiving parts on the bottom wall of the external receiving part to remove the strip from the bottom wall of the external receiving part, thereby creating a clear separation part between the two internal receiving parts. For this purpose, a cutting unit is used which is provided with two parallel and adjacent rotary blades that are partially accommodated in a collection chamber where a suction action is carried out to capture and remove the strip immediately after it is separated from the rest of the bottom wall.
[0011] However, it is not uncommon that even after cutting by the two rotary blades, the strip remains stuck in the bottom wall and thus cannot be removed by suction, and therefore, downstream of the cutting unit, some "wallet-style" cigarette packaging boxes still have more or less the strip fixed in place on the bottom wall of the external receiving part. This can cause various problems, such as the strip being lost in the machine before applying the transparent plastic outer wrapping, or (with the transparent plastic outer wrapping) the strip being wrapped together with the cigarette packaging box in completely random positions, giving the end user the impression of a poor-quality cigarette packaging box.
[0012] In addition, it may also happen that after cutting by the two rotary blades, the strip remains stuck between the two rotary blades, ultimately causing a blockage that forces the packaging machine to stop.
[0013] Patent application WO2005054056A1 describes a machine configured to make a "wallet-style" cigarette packaging box, which includes: a first machine for forming a first cigarette group in a wrapper and connected to a first internal frame; a second machine for forming a second cigarette group in a wrapper and connected to a second internal frame; and a third machine for combining the two wrapped cigarette groups into a single hinged packaging box with a vertical hinge.
[0014] Patent application WO2016166692A1 describes a wrapping unit in which a strip of wrapping material undergoes a process involving the removal of material by laser.
[0015] Patent application EP2253547A1 describes a rigid cigarette pack with a hinged lid that houses two different groups of cigarettes. Summary of the Invention

[0038] In Figure 1 and Figure 2 , reference numeral 1 generally denotes a "wallet-style" rigid cigarette pack, which includes two internal accommodation parts 2 (respectively in Figure 5 and Figure 6shown), these receiving portions receive the corresponding wrapped cigarette packs 3 (in Figure 3 and Figure 4 shown). In particular, Figure 3 shows the bare cigarette pack 3 (i.e., without wrapping), while Figure 4 shows the wrapped cigarette pack 3 (i.e., a soft wrap provided with an upper peelable portion).
[0039] According to the (non - limiting) embodiment shown, two cigarette packs 3 (and thus two internal receiving portions 2) have different sizes, i.e., one cigarette pack 3 is larger than the other cigarette pack 3.
[0040] As Figure 1 and Figure 2 shown, the cigarette pack 1 includes an external receiving portion 4 that encloses (receives) the two internal receiving portions 2 therein and has a hinge portion that enables the two internal receiving portions 2 to rotate between a closed configuration (as Figure 1 shown) in which the two internal receiving portions 2 are stacked on top of each other and an open configuration (as Figure 2 shown) in which the two internal receiving portions 2 are separated. In addition, the external receiving portion 4 is provided with a lid 5 that is hinged to the external receiving portion 4 and, when in the closed position (as Figure 1 shown), the lid encloses the upper portions of the two internal receiving portions 2.
[0041] To produce the cigarette pack 1, two cigarette packs 3 are first formed, the corresponding wrappings are wrapped around the cigarette packs 3, and then two internal receiving portions 2 are manufactured by using two corresponding blanks (known and not shown) that are folded (and stabilized with glue) around the corresponding cigarette packs 3. After formation, the two internal receiving portions 2 (receiving the corresponding wrapped cigarette packs 3) are joined (stacked) together, and then the external receiving portion 4 is made by folding (and stabilizing with glue) a blank 6 (as Figure 7 shown) around the two mutually - joined internal receiving portions 2.
[0042] According to Figure 1 and Figure 2 shown, after folding the blank 6, the external receiving portion 4 has a bottom wall 7 and side walls 7. The bottom wall is glued to the two internal receiving portions 2 (thus not allowing the internal receiving portions 2 to rotate relative to each other), and the side walls are glued to the two internal receiving portions 2 (thus not allowing the internal receiving portions 2 to rotate relative to each other); thus, cuts need to be formed in the bottom wall 7 and side walls 7 of the external receiving portion 4 to enable the two internal receiving portions 2 to separate (i.e., to allow the two internal receiving portions 2 to rotate relative to each other). It is important to note that during the folding of the blank 6 to form the external receiving portion 4, the wall 7 (which is part of the blank 6 and thus part of the external receiving portion 4) is pressed against the two wrapped groups of smoking articles 3 (in the case of insertion into the corresponding internal receiving portions 2).
[0043] In Figure 8 , reference numeral 8 generally shows a cutting unit in which a completely formed cigarette pack 1 is fed to perform cutting of the walls 7 of the outer receiving portion 4 of each cigarette pack 1 (in Figure 8 , for simplicity only the cutting of the bottom wall 7 is shown, but the cutting of the side walls 7 is performed in the same way).
[0044] Specifically, as better shown in Figure 9 , in order to create a clear separating portion between the two inner receiving portions 2, the cutting unit 8 produces double main through-cuts 9 (i.e., two main through-cuts 9 spaced apart from each other and parallel) to remove the strip 10 (band) of each wall 7; that is, the cutting unit 8 removes the corresponding relatively thin central portion (strip 10) from each wall 7 of the cigarette pack 1 to separate the two inner receiving portions 2.
[0045] In the embodiment shown in the drawings, the two main cuts 9 separating the strip 10 from the rest of each wall 7 are parallel to each other, and thus the strip 10 has a constant width; according to different embodiments not shown, the two main cuts 9 separating the strip 10 from the rest of each wall 7 may not be completely parallel to each other (i.e., these two main cuts may be slightly asymptotic or diverging relative to each other), and thus the strip 10 may have a varying width.
[0046] As Figure 8 shown, the cutting unit 8 includes a conveyor that continuously feeds the cigarette pack 1 along a straight path P, which conveyor is manufactured, for example, as described in patent applications EP1916188A1 and EP2172399A1. In addition, the cutting unit 8 includes (at least) one emitter 11 configured to focus a laser beam on each wall 7 of each blank 6 (or the corresponding outer receiving portion 4 formed by the blank 6) to form the main through-cut 9 by sublimating (vaporizing) a part of the wrapping material of the blank 6. In other words, for each cigarette pack 1 fed along the path P, the main through-cuts 9 separating the strip 10 from the rest of each wall 7 are formed by a laser beam focused on the wall 7 of the outer receiving portion 4 (or more precisely, on the blank 6 forming the outer receiving portion 4) to sublimate (vaporize) a part of the wrapping material.
[0047] For example, the laser spot is focused on each wall 7 and is moved by using a mirror driven by a galvanometer (laser marking machine and biaxial scanning head), but there may be an additional drive acting on the laser focus (marking machine and scanning head with 3 or more axes). Generally, during the formation of the main cut 9 by the emitter 11, the cigarette pack 1 may be stationary or moving; the position of the cigarette pack 1 during any movement can be tracked by a position sensor connected to the conveyor mechanism or by a vision optical system.
[0048] The main cut 9 produced by the emitter 11 can be straight or follow a freely programmable trajectory.
[0049] As previously mentioned, in each cigarette pack 1 and in each wall 7, two main through cuts 9 spaced apart from each other define a strip 10, which is the disposable part of the wall, i.e., the strip is the part that must be separated and removed from the rest of the wall 7. According to Figure 9 As shown, in order to simplify the separation and removal of the strip 10 (which constitutes the disposable part of each wall 7), the cutting unit 8 can form not only two main through cuts 9, but also a series of secondary through cuts 12 including dividing the strip 10 (i.e., the disposable part) into a plurality of smaller parts 13 that are easier to separate and remove from each wall 7. In particular, each secondary cut 12 is transverse (perpendicular or inclined in various forms) to the two main cuts 9 and connects the two main cuts 9 together (to divide the disposable part into two parts 13). In Figure 9 In the illustrated embodiment, a plurality of secondary cuts 12 are made to divide the strip 10 (i.e., the disposable part) into a plurality of parts 13; according to other embodiments not shown, a single secondary cut 12 can be made to divide the strip 10 (i.e., the disposable part) into only two parts 13.
[0050] According to Figure 8 In the preferred embodiment shown, the cutting unit 8 includes a suction device 14 that is arranged at the cutting station where the laser beam is focused on the wall 7 of each cigarette pack 1 and is configured to suck away the disposable part (i.e., the strip 10 that can be a whole or divided into several parts 13) from the wall 7.
[0051] In addition, the cutting unit 8 further includes a suction system for sucking away the soot (dust) generated after sublimating (vaporizing) the packaging material that makes up each wall 7. According to a possible embodiment, the suction device 14 can suck away the disposable part (i.e., the strip 10 that can be a whole or divided into several parts 13) as well as the soot (dust) generated after sublimating (vaporizing) the packaging material; downstream of the suction device 14, the packaging material can be separated from the soot (dust) by a suitable filter for different treatments.
[0052] In the embodiment shown in the figures, the cutting unit 8 makes cuts on two different walls 7 (i.e., both the bottom wall 7 and the side wall 7) of each cigarette pack 1; according to different and completely equivalent embodiments, the blank 6 is shaped differently and thus the cutting unit 8 performs cuts only on a single wall 7 of each cigarette pack 1 (i.e., only on the bottom wall 7 or only on the side wall 7).
[0053] In summary, for each cigarette pack 1 in the forming unit, two wrapped cigarette groups 3 are formed. In the first wrapping unit, two internal receiving portions 2 are formed around the two wrapped cigarette groups 3. In the second wrapping unit, the blank 6 is folded around the two internal receiving portions 2 (i.e., around the two wrapped cigarette groups 3) to form an external receiving portion 4, and in this step, the bottom wall 7 of the external receiving portion 4 is glued (at least) to the two internal receiving portions 2; finally, the cutting unit 8 makes two main cuts 9 (at least) on the bottom wall 7 of the external receiving portion 4, which are spaced apart from each other and extend between the opposite ends of the bottom wall 7, and separates the first part of the wall 7 glued to the first internal receiving portion 2 from the second part of the wall 7 glued to the second internal receiving portion 2.
[0054] In addition to making the through cuts 9 (and possibly the cuts 12), the cutting unit 8 can also be used to perform other treatments on each cigarette pack 1; for example, the laser emitted by the emitter 11 (in addition to possibly making the cuts 9 and 12) can also be used to generate vector or raster alphanumeric markings, barcodes, logos or even graphic and decorative elements on the walls of the external receiving portion 4. Generally, the operating parameters of the emitter 11 (power, speed, frequency, repetition rate, diameter and spot focus) can be different from one process to another; in addition, even in the same process, the operating parameters of the emitter 11 can be varied.
[0055] In Figures 1 to 9 and Figure 11 the embodiment shown, in each cigarette pack 1, the cutting unit 8 forms two main cuts 9 spaced apart from each other, which extend between the opposite ends of the wall 7 and separate the strip 10 (i.e., the disposable part) from each wall 7.
[0056] According to Figure 12 a different embodiment shown, in each cigarette pack 1, the cutting unit 8 makes a single main cut 9, which extends between the opposite ends of each wall 7; in this embodiment, in any case, each wall 7 is divided into two parts (each part is glued only to the corresponding internal receiving portion 2), but no disposable part (i.e., any strip 10 to be removed from the wall 7) is formed.
[0057] According to Figure 13Another embodiment shown is that in each cigarette pack 1, the cutting unit 8 forms two or even more main cuts 9 adjacent to and in contact with each other in each wall 7 (i.e., there is no remaining wrapping material between two adjacent main cuts), so as to create a wider separation part in the wall 7 (i.e., the wall 7 is divided into two parts in any case), but no discardable part is formed (i.e., no strip 10 to be removed from the wall 7). In other words, in Figure 13 the embodiment shown, through multiple adjacent channels (travels) of the laser, the strip 10 (i.e., the discardable part) is completely "broken down" (vaporized, sublimated), that is, through multiple main cuts 9 adjacent to and in contact with each other, there is no remaining wrapping material (i.e., waste to be mechanically removed) between these main cuts.
[0058] By comparing Figure 10 and Figure 11 it can be understood that the difference between the double main cuts 9 ([[]] Figure 10 ) mechanically produced by the double-rotating blade and the double main cuts 9 ([[]] Figure 11 ) produced by the laser is that the main cuts 9 produced by the laser have excellent separation performance and the main cuts extend to the glue between the wall 7 and the lower receiving part 2 (and may even remove part of the glue between the wall 7 and the lower receiving part 2 and vaporize it). In order to prevent the blade from being soiled by the glue between the wall 7 and the lower receiving part 2, the mechanically produced main cuts 9 must be very thin (therefore uncertain) near the glue; thus, the strip 10 ([[]] Figure 11 ) defined by the double main cuts 9 performed by the laser can be removed very simply because it no longer has any type of residual connection with the wall 7, while the strip 10 ([[]] Figure 10 ) defined by the main cuts 9 mechanically performed by the double-rotating blade is much more difficult to remove because there are some residual connections with the wall 7 (and it is very difficult to eliminate them in advance without soiling the rotating blade with glue). In Figure 14 and Figure 15In the different embodiments shown, a group of cigarettes 3 in a single package is obtained, and the group of cigarettes in the single package is inserted in a slidable manner into a single internal receiving portion 2 which is received in an external receiving portion 4 (i.e., the blank 6 wraps around the single internal receiving portion 2, so that the single internal receiving portion is located within the external receiving portion 4), and is provided with a single main through-cut 9 which is self-closed and separates a button 16 glued to the underlying internal receiving portion 2 from the side wall 15 of the external receiving portion 4. In this embodiment, the main cut 9 may also be discontinuous (to leave a residual connection point that must be broken during the first opening of the cigarette packaging box 1 as a guarantee of integrity). In addition, in this embodiment, the button 16 produced by the main cut 9 has the function of making the opening of the cigarette packaging box 1 more "complicated" (i.e., by sliding the internal receiving portion 2 out of the external receiving portion 4), so as to make the opening of the cigarette packaging box "child-proof".
[0059] In Figures 16 to 19 In the different embodiments shown, a group of cigarettes 3 in a single package is made, and the group of cigarettes in the single package is directly inserted into the external receiving portion 4 (i.e., the blank 6 directly wraps around the group of cigarettes 3 in the package and there is no internal receiving portion 2), the external receiving portion 4 is provided with a sliding lid 5, and is provided with a single main through-cut 9 which is formed in the rear wall 17 of the external receiving portion 4 and creates a complete separation between the external receiving portion 4 and the sliding lid 5, thereby allowing the sliding lid 5 to slide relative to the external receiving portion 4 (i.e., the sliding lid 5 is initially connected to the rest of the external receiving portion 4 at the rear wall 17 and is completely separated from the rest of the external receiving portion 4 only due to the main cut 9). In this embodiment, the main cut 9 may also be discontinuous (to leave a residual connection point that must be broken during the first opening of the cigarette packaging box 1 as a guarantee of integrity). In addition, in this embodiment, the main cut 9 may be straight (as Figure 16 and Figure 17 shown), or may be serrated with sharp edges or rounded edges (as Figure 18 and Figure 19 shown).
[0060] Obviously, in Figures 14 to 19 the embodiments shown, two main cuts 9 side by side with each other may also be formed in the walls 15 and 17 to separate and remove the strip 10 from the corresponding walls 15 and 17.
[0061] Without departing from the scope of the present invention, the embodiments described herein may be combined with each other.
[0062] The above manufacturing method has many advantages.
[0063] First, the above manufacturing method allows for the efficient and effective manufacture of the rigid cigarette pack 1, allowing the use of a blank 6 which is simpler and faster to manufacture and fold since some of the cutting operations of the blank 6 are carried out after (or during) the folding of the blank 6.
[0064] Furthermore, even when there is glue below the main cut 9, the above manufacturing method allows for the production of the main cut 9 with extremely high precision, without any risk of errors and contamination (and thus without the need for any regular cleaning).
[0065] When necessary, the above manufacturing method allows for the removal of any strip 10 (i.e., any discardable part) in a simple and safe manner after cutting, thus preventing the strip 10 (or a strip 10) from remaining in contact with the bottom wall 7 also downstream of the cutting unit 8.
[0066] Finally, compared to similar known manufacturing methods, the above manufacturing method is simple and low-cost to implement and it requires quick modification using commercial parts (such as the emitter 11) or parts that can be easily obtained by standard machining.
[0067] The embodiment shown in the drawings relates to the manufacture of a cigarette pack, but the invention can also be applied, without substantial modification, to the production of packs for any other type of smoking article (such as cigar packs, liquid vaporizing electronic cigarette packs, next-generation smokeless cigarette packs, etc.).
