Definitions

  • This invention relates to a method and a machine for making multisegment articles, specifically for assembling rod-shaped articles, preferably for the tobacco industry or the like (aerosol generators).
  • composite filters may be made by progressively assembling different segments in suction seats of a conveying system, as described in EP1393640.
  • each suction seat receives successive filter segments until each seat contains the same complete sequence of filter segments.
  • These complete sequences which correspond to two composite filters to be obtained, are then released into a single forming beam, where they are wrapped in a paper web and then cut to obtain a succession of composite filters.
  • this technical solution may lead to the production of complete sequences of excessive length, or in any case, non-standard length.
  • This introduces production constraints on the lengths obtainable for these sequences or, alternatively, requires configuring the machine in accordance with non-standard sizes which, what is more, may lead to further complications when the sequences are subsequently transferred to the forming beam, especially if the transfer devices used are those known as “spider” devices, which would need to operate with non-standard lengths.
  • the basic technical purpose of this invention is to provide a method and a machine for making multisegment articles to overcome the above mentioned disadvantages of the prior art. More specifically, the aim of this invention is to provide a method and a machine for making multisegment articles and which are operable in a simple and reliable manner.
  • a further aim of the invention is to provide a method and a machine for making multisegment articles and which allow making a wide range of articles, specifically articles of different sizes.
  • the method according to the invention is implemented in the context of a “single-rod” machine, that is to say, in a machine in which the sequences of segments are fed to a single continuous rod, which is subsequently wrapped and cut into single multisegment articles.
  • the method comprises the steps of preparing a plurality of segments of different kinds, assembling the segments of different kinds to make an alternating succession of first and second units advancing transversely to the longitudinal axis of the segments and wherein at least the first units are each made up of at least two segments of different kinds, and assembling the units in a single forming beam to form a single continuous rod defined by a predetermined sequence of segments of different kinds, wherein the step of assembling the segments of different kinds to make an alternating succession of first and second units is carried out in such a way that the segments of each of the aforesaid different kinds form part only of the first or the second unit.
  • the segments of each kind are fed in the form of respective successions of segments advancing transversely to their axes and the step of assembling the segments of different kinds to make an alternating succession of first and second units is carried out in such a way that the segments of each succession (having the same properties) form part of only the first or only the second unit but not both. Consequently, the multisegment articles obtained with this method, defined by combining the segments of a first and a second unit, adjacent with each other, comprise segments having different properties since segments having the same properties are never placed in both the first and the second units.
  • the continuous rod is formed by combining the first and second units in such a way that the first and second units are abutted end to end or, alternatively, have empty spaces between them.
  • the individual segments may contain or be made from filter material, aerosol generating material, cooling material, heating elements or they may be made in the form of hollow tubular segments. According to the method of the invention, three or more of these kinds may be fed in and assembled in the specified manner.
  • the segments have the shape of rods, differing in length and, more specifically, are cylindrical in shape, with circular cross section.
  • the method according to the invention comprises the following steps:
  • first, second and third segments to make an alternating succession of first and second units advancing transversely to the longitudinal axis of the segments and wherein the first units comprise at least a first and a second segment and the second units comprise at least a third segment;
  • any additional successions of segments with further, different properties are assembled in such a way as to be included exclusively in the first or the second units.
  • the segments forming part of the respective unit may be further processed before being assembled to form the continuous rod: for example, they may be cut and spaced apart to allow a segment of a different kind to be inserted between them.
  • the segments may be cut and spaced before they are released to form part of the respective unit, and thus, more specifically, released in pairs with a space in the middle to allow inserting a successive segment having different properties.
  • the method may be carried out by assembling at least first, second and third segments (having respective different properties) on conveying means to make an alternating succession of first and second units advancing transversely to the longitudinal axis of the segments wherein the first units comprise at least one first segment and the second units comprise at least one second segment, and wherein the first units and the second units each also comprise a third segment, wherein the step of assembling the segments of different kinds to make an alternating succession of first and second units is carried out in such a way that the first segments form part only of the first units and the second segments form part only of the second units and in such a way that the first and second units each comprise a third segment, and wherein the step of assembling the first, second and third segments on the conveying means is carried out by releasing each third segment on the conveying means before releasing the first and/or the second segments, preferably before releasing both the first and the second segments.
  • the third segments are released onto the conveying means at a release zone located upstream of the respective release zone where the first and/or the second segments are released onto the conveying means.
  • the method may also comprise feeding fourth segments (of a different kind from the first, second and third segments) and the step of assembling the segments of different kinds to make an alternating succession of first and second units is carried out in such a way that the first and second units each also comprise a fourth segment in addition to the third segment.
  • the fourth segment may be positioned in contact with the third segment.
  • the first and second units each comprise a third and a fourth segment, while only the first units comprise one or more first segments and only the second units comprise one or more second segments.
  • the third and fourth segments are fed to the respective units in distinct steps.
  • they may be assembled with each other before they are released into the units and thus they may be released simultaneously.
  • the method is carried out by assembling at least first, second, third and fourth segments (having respective different properties) on conveying means to make an alternating succession of first and second units advancing transversely to the longitudinal axis of the segments wherein the first units comprise at least a first and a second segment (but not third and fourth segments) and, conversely, the second units comprise at least a third and a fourth segment (but not first and second segments).
  • each first unit comprises a second segment interposed between two first segments, while each second unit comprises a fourth segment interposed between two third segments.
  • the two units are symmetrical about a common plane of symmetry.
  • first and the second units may be made on axially offset zones of a single drum and are then axially centred to define a single alternating succession of the first and second units.
  • the overall lengths of the first and second units may be identical or different.
  • An assembling machine for making multisegment articles according to this invention comprises a plurality of feed lines configured to feed respective successions of segments having different properties, and conveying means disposed and/or configured to receive respective segments from the feed lines, wherein the conveying means define a succession of receiving seats, configured to receive one or more of the segments each and to advance the segments transversely, and wherein the machine is configured and/or set in such a way that at least a first and a second of the feed lines release the respective segments exclusively in first seats of the conveying means and at least a third of the feed lines releases the respective segments exclusively in second seats of the conveying means, where the first and second seats are disposed alternately along a conveying direction defined by the conveying means.
  • Each unit is accommodated in a corresponding seat.
  • the conveying means comprise a succession of drums, at least some of which are configured to define a pair of axially juxtaposed, peripheral conveying surfaces, for example, forming contiguous portions of a single peripheral mantle.
  • the first of these peripheral conveying surfaces is designed to combine and/or transport first units obtained by a first combination of segments, while the other peripheral surface is designed to combine and/or transport second units obtained by a second combination of segments, different from the first combination.
  • the first and second units are then centred by a centring drum to define a single alternating succession of first and second units.

  • the numeral 1 denotes in its entirety a machine for making multisegment articles in accordance with this invention.
  • the individual segments may be segments of filter material, segments of aerosol generating material, segments of tobacco, segments of cooling material, heating elements or hollow tubular segments. According to the method of the invention, three or more of these kinds may be fed in and assembled in the specified manner.
  • the segments have the shape of rods, which may differ in length and which, more specifically, are cylindrical in shape, with circular cross section.
  • segments of filter material for making composite filters are considered; however, the same concepts in terms of operating steps also apply to segments of a different kind, for example, belonging to the above list of segments.
  • the segments used may not only be segments of the same nature but having different properties (for example, filter segments with different filtering properties) but also segments of a different nature (for example, tubular segments in combination with segments of filter material and heating segments). Thus, all the possible combinations fall within the scope of the invention.
  • the machine 1 comprises a plurality of feed lines 10, 20, 30, 40 (four in the embodiment illustrated, but the number may be any number greater than or equal to three), each configured to feed filter segments 1 , 2, 3 4 of a specific kind.
  • the filter segments 1 , 2, 3, 4 fed by each feed line 10, 20, 30, 40 are all of the same kind, which is different from the filter segments 1 , 2, 3, 4 fed by the other feed lines.
  • these filter segments have a rod shape, for example, with circular transverse cross section.
  • Each feed line 10, 20, 30, 40 comprises, respectively, an upper buffer hopper 11 , 21 , 31 , 41 , intended to contain the respective segments 1 , 2, 3, 4, and one or more transfer drums 12, 13, 14; 22, 23, 24; 32, 33, 34; 42, 43, 44, located downstream of the respective buffer hopper 11 , 21 , 31 , 41 and provided with peripheral seats, specifically suction seats, for holding respective filter segments.
  • one or more of the transfer drums 12, 13, 14; 22, 23, 24; 32, 33, 34; 42, 43, 44 may be provided with blades for cutting the segments 1, 2, 3, 4.
  • the machine 1 also comprises conveying means 50, located in a bottom portion of the machine and interconnected with at least one transfer drum 12, 13, 14; 22, 23, 24; 32, 33, 34; 42, 43, 44 of each feed line 10, 20, 30, 40.
  • the conveying means 50 are disposed and/or configured to receive respective segments 1 , 2, 3, 4 from the feed lines 10, 20, 30, 40 and define a succession of receiving seats configured to receive one or more of the segments 1 , 2, 3, 4 and to feed the segments 1 , 2, 3, 4 transversely.
  • the conveying means 50 comprise a succession of suction drums.
  • Figure 2A shows a first operating diagram of the machine 1 described above.
  • the filter segments 1 , 2, 3, 4 of different kinds coming from the feed lines 10, 20, 30, 40 are transferred to the receiving seats of the conveying means 50 to make an alternating succession of filter units 60, 70 advancing transversely to the longitudinal axis of the segments 1 , 2, 3, 4 and located inside consecutive receiving seats.
  • At least the first filter units 60 are each made up of at least two segments 1, 2 of different kinds, fed by different feed lines 10, 20 (not necessarily adjacent to each other).
  • the second filter units 70 are also each made up of at least two segments 3, 4 of different kinds, fed by different feed lines 30, 40 (not necessarily adjacent to each other).
  • the first and second filter units 60, 70 thus made and completed may have the same length or different lengths according to the size of the individual filter segments 1 , 2, 3, 4 which make them up.
  • the second filter units 70 also comprise at least one filter segment 3 of double length and, in the embodiment of Figures 2C and 2D, consist of a single filter segment 3 of double length.
  • the filter units 60, 70 are then assembled with each other in a single forming beam 80 ( Figure 3) to which they are fed by a transfer “spider” 90 of known type (specifically provided with working units mounted pivotably on a horizontal-axis transfer wheel and driven in such a way that, as the wheel rotates, the working units keep the same orientation, specifically horizontal) to form a single continuous rod 100 defined by a predetermined sequence of segments of different kinds.
  • this continuous rod 100 is wrapped in a continuous web, specifically a paper web, and then cut into composite filters 110 by a transverse cut, preferably made at the double length segment 3.
  • the transfer “spider” 90 is adjusted or set in such a way as to compensate for the difference in length between two consecutive filter units 60, 70. This is accomplished by setting (that is to say, selecting a specific wheel size) or adjusting the individual working units in such a way as to position them at a distance from each other (measured circumferentially at the pivot pins of the working units) which is equal to the average length of the two filter units 60, 70, gripped and transferred by respective consecutive working units of the transfer spider 90, and which, if necessary, may be increased or decreased by a correction factor depending, for example, on the geometry of the working units. That way, the part of the length exceeding the theoretical length of the longer filter unit compensates for the gap left by the shorter filter unit.
  • first units 60 and the second units 70 allows obtaining a continuous rod 80 made up of a sequence of segments 1 , 2, 3, 4 which may even be very long (it would be complicated, if not impossible, to manage a “long” sequence if the segments 1 , 2, 3, 4 were all in the same seat).
  • the step of assembling the filter segments 1 , 2, 3, 4 of different kinds to make an alternating succession of first and second filter units 60, 70 is carried out in such a way that the segments 1 , 2, 3, 4 of each kind are fed only to the first or the second filter unit 60, 70.
  • the first units 60 and the second units 70 do not have segments in common.
  • the first filter units 60 comprise only first and second filter segments 1 , 2 belonging to respective kinds, but not third and fourth filter segments 3, 4, which, in turn, form part only of the second filter units 70 (but not of the first units 60).
  • each composite filter 90 comprises segments of all the kinds released by the active feed lines 10, 20, 30, 40.
  • the continuous rod 80 may have gaps between a first and a second unit 60, 70 (and/or vice versa) instead of each first and each second unit 60, 70 being positioned in contact with each other.
  • the machine 1 comprises (in addition to the four feed lines 10, 20, 30, 40) one or more further feed lines configured to feed one or more successions of further filter segments of kinds different from the first, second, third and fourth filter segments 1 , 2, 3, 4.
  • the step of assembling the filter segments of different kinds is in any case carried out in such a way that the further filter segments of each kind form part only of the first or the second filter units (but not both).
  • the method comprises substantially the same steps but the first filter segments 1 , when they are already in the respective receiving seats of the conveying means 50, are cut and spaced from each other to create space for inserting a second filter segment 2 (or a pair of second filter segments 2).
  • the third filter segments 3 are cut and spaced from each other but in this case, this is done before the third filter segments 3 are fed into the respective receiving seats of the conveying means 50 (hence, when released, the segments of each pair are already spaced apart).
  • one double-length fourth segment 4 is inserted between the two third segments 3 which have been spaced apart or, alternatively, a pair of juxtaposed, single-length fourth segments 4 is inserted between them.
  • the third and fourth feed lines 30, 40 release segments of the same kind, that is to say, third filter segments 3 (double-length filter segments or, alternatively, pairs of juxtaposed single-length third segments 3) but in this case, the third and fourth feed lines 30, 40 feed the respective third segments 3 to respective alternate receiving seats to define respective second units 70 alternated with each other so that the filters are assembled at a higher speed.
  • the first units 60 and the second units 70 may comprise a single segment each. Assuming, for example, that the first units 60 comprise only the first segment 1 and that the second units 70 comprise only the second segment 2, assembling the first units 60 and the second units 70 results in the formation of a rod comprising first segments 1 alternated with second segments 2.
  • Figure 4 shows a variant embodiment of the invention in which the method is carried out by assembling at least first, second and third segments 1 , 2, 3 (having respective different properties) on conveying means to make an alternating succession of first and second units 60, 70 advancing transversely to the longitudinal axis of the segments, wherein the first units 60 comprise at least a first segment 1 and the second units 70 comprise at least a second segment 2 and wherein each first unit 60 and each second unit 70 also comprise a third segment 3.
  • each first unit 60 thus comprises only a first segment 1 and a third segment 3
  • each second unit 70 comprises only a second segment 2 and a third segment 3.
  • the step of assembling the segments 1 , 2, 3 is thus carried out in such a way that the first segments 1 form part only of the first units 60 and the second segments 2 form part only of the second units 70. Further, the step of assembling the segments 1 , 2, 3 is carried out in such a way that the first and second units 60, 70 each comprise a third segment 3.
  • the third segments 3 are released onto the conveying means before the first and/or the second segments 1 , 2 are released, preferably before both the first and the second segments 1 and 2 are released.
  • the third segments 3 are released onto the conveying means 50 at a release zone located upstream of the respective release zone where the first and/or the second segments 1 , 2 are released onto the conveying means 50.
  • the method of the invention may also comprise feeding first, second, third and fourth filter segments 1 , 2, 3, 4 of different kinds and the step of assembling the segments of different kinds to make an alternating succession of first and second units 60, 70 is carried out in such a way that the first and second units 60, 70 each also comprise a fourth segment 4 in addition to the third segment 3.
  • the first and second units 60, 70 each also comprise a fourth segment 4 in addition to the third segment 3.
  • the third and fourth segments 3, 4 are fed to the respective units 60, 70 in distinct steps. Alternatively, they may be assembled with each other before they are released into the units 60, 70 and thus they may be released simultaneously onto the conveying means 50.
  • the third segments 3 are obtained by cutting a piece of rod of multiple length into single segments 3 which are then offset transversely and some of which are translated axially to form a succession of pairs of third segments 3, one after the other and parallel, but not aligned, with each other, thereby forming a zig-zagged succession (in other words, with the respective ends not aligned one after the other but obtained by axially displacing the two third segments 3 of each pair relative to each other).
  • the same is done on the fourth segments 4 to form a matching (mirrored) zig-zagged configuration so that when the third segments 3 are assembled with the fourth segments 4, pairs of segments 3, 4 are obtained in which two successive third segments 3 have a fourth segment 4 inserted between them and vice versa.
  • each fourth segment 4 is thus juxtaposed with a corresponding third segment 3 and is also interposed between a third segment 3 preceding it and a third segment 3 following it.
  • each third segment 3 is thus juxtaposed with a corresponding fourth segment 4 and is also interposed between a fourth segment 4 preceding it and a fourth segment 4 following it.
  • the zig-zagged succession of the fourth segments 4 is obtained by feeding fourth segments 4 of final length, that is to say, fourth segments 4 whose length is the length they have in the first units 60 and the second units 70.
  • the fourth segments 4 may be obtained by cutting a piece of rod of multiple length into single segments 4 which are then offset transversely and some of which are translated axially to form a succession of pairs of fourth segments 4, one after the other and parallel, but not aligned, with each other, thereby forming a zig-zagged succession (similarly to what is shown in Figure 5 with reference to the third segments 3).
  • joins between the third segment 3 and the fourth segment 4 of the pairs of third and fourth segments 3, 4 lie in a single, common longitudinal plane.
  • each pair of segments 3, 4 has been formed in this way, at least one first segment 1 (first units 60) or at least one second segment 2 (second units 70) is brought into abutment with it on its outer side.
  • the step of assembling the segments 1 , 2, 3, 4 of different kinds to make an alternating succession of first and second units 60, 70 is carried out in such a way that each third segment 3 is also juxtaposed with a corresponding fourth segment 4 so that the third segment 3 of the first units 60 is juxtaposed with a first side of the fourth segment 4 and the third segment 3 of the second units 70 is juxtaposed with a second side (opposite to the first side) of the fourth segment 4.
  • the method is carried out by assembling at least first, second, third and fourth segments 1 , 2, 3, 4 of different kinds to make an alternating succession of first and second units 60, 70 advancing transversely, wherein the first units 60 comprise at least a first and a second segment 1 , 2 (but not third and fourth segments 3, 4) and, conversely, the second units 70 comprise at least a third and a fourth segment 3, 4 (but not first and second segments 1 , 2).
  • the two units 60, 70 do not have any segment in common.
  • each first unit 60 comprises a second segment 2 interposed between two first segments 1
  • each second unit 70 comprises a fourth segment 4 interposed between two third segments 3.
  • the two units 60, 70 are shaped and disposed symmetrically about a common plane of symmetry.
  • the two units 60, 70 are formed by axially spacing pairs of segments of the same kind (specifically, pairs of first and third segments 1 , 3) in a succession of downfeed rollers forming part of the respective feed line 10, 30.
  • first and second units 60, 70 are, instead, made on axially offset zones of a single drum of the conveying means 50 and are then axially centred to define a single alternating succession of the first and second units 60, 70.
  • the first segments 1 are preferably obtained by cutting a piece of rod of multiple length using a spacing drum located on the respective feed line 10 of the first segments 1 (hence on a “downfeed” stretch where the segments move down towards the conveying means 50). The same applies to the third segments 3, at the respective feed line 30.
  • Figure 7 shows a variant embodiment very similar to that of Figure 6 but differing in that the second units 70 are formed on the conveying means 50, hence in a zone at the bottom of the assembling machine and, more specifically, on the same drum (or on the same drums) that transports the first units 60 but in such a way that the first units 60 and the second units 70 are housed on respective, axially spaced (side by side) portions (peripheral surfaces) of the same drum or of the same drums, hence while they are being transported and/or assembled side by side and preferably with spacing that is twice the final spacing to be obtained.
  • first units 60 and the second units 70 are assembled with each other on a centring drum to form a single alternating succession of first units 60 and second units 70, one after the other with single spacing.
  • the present invention achieves the preset aims, overcoming the disadvantages of the prior art.
  • the machine and method according to the invention allow making multisegment articles using, for each article, two consecutive seats of the conveying means so as to divide the length of the sequences into two parts (first and second units). This also allows varying the lengths of the individual segments in a range wide enough to cover a large number of formats but without having to set the machine to non-standard format conditions.

Abstract

L'invention concerne un procédé de fabrication d'articles à segments multiples comprenant les étapes consistant à : préparer au moins une succession de premiers segments (1), une succession de seconds segments (2) et une succession de troisièmes segments (3), les premiers, seconds et troisièmes segments (1, 2, 3) étant des segments de différents types ; assembler les premiers, seconds et troisièmes segments (1, 2, 3) pour réaliser une succession alternée de premières et secondes unités (60, 70) avançant transversalement à l'axe longitudinal des segments (1, 2, 3) et les premières unités (60) comprenant au moins un premier et un second segment (1, 2) et les secondes unités (70) comprenant au moins un troisième segment (3) ; assembler les unités (60, 70) dans un seul faisceau de formation (80) pour former une seule tige continue (100) définie par une séquence prédéterminée de segments (1, 2, 3) de différents types. L'étape d'assemblage des segments (1, 2, 3) de différents types pour réaliser une succession alternée de premières et secondes unités (60, 70) est réalisée de telle sorte que les premiers et seconds segments (1, 2) fassent seulement partie des premières unités (60) et que les troisièmes segments (3) fassent seulement partie des deuxièmes unités (70).
