Description

The present invention relates to telescopic coaxial filter tobacco and methods for producing this type of tobacco.

The present invention also relates to a machine for producing a filter rod suitable for producing a telescopic coaxial filter, and a filter chip mounting machine for producing a telescopic coaxial filter / cigarette.

The term "cigarette" is used to refer to multiple products such as cigars, cigarillos, electronic cigarettes or smoker products.

Known types of tobacco generally include a filter that is inhaled by the consumer through the mouth and is connected to a tobacco stick, eg, with a tobacco plant (tobacco).

For example, from WO2014 / 102528-A1 and US Pat. No. 4,904,308 (US4904308), at least part of the filter can be moved between two positions with respect to the tobacco stick. Telescopic filter cigarettes are known.

This type of tobacco is variable in length and, if desired, changes the aeration of the tobacco during use by allowing air to pass through channels not included in the combustion. It is designed.

Known telescopic cigarettes have stopping means for stopping the movement of the stretchable portion at a fully extended position.

These stopping means are embodied by a piece of paper (a piece of paper) wrapped around the outside of the cigarette that forms a noticeably significant step along the outer surface.

Not only does this step have a negative effect on the appearance of the cigarette, but it also has a negative effect during production, especially during handling and packaging, and during use, especially when taken out of the packaging box.

Also, known telescopic tobacco is difficult to produce and relatively unreliable because it causes sliding problems even with very small rolling errors.

Therefore, a main technical object of the present invention is to propose a tobacco without the above-mentioned drawbacks, a method for producing a tobacco, a machine for producing a filter rod, and a filter chip mounting machine.

An object of the present invention is to provide a tobacco that does not change the appearance of the tobacco in order to obtain a constant external size, a method for producing the tobacco, a machine for producing a filter rod, and a filter chip mounting machine.

Specific technical objectives and intents are achieved by the method of producing the tobacco according to claim 1 and the tobacco according to claim 21. Also, the specific technical objectives and intents are fully achieved by the machine for producing the filter rod according to claim 12 and the filter chip mounting machine according to claim 19.

As mentioned above, the tobacco of the present invention is a specific example of a smoker product that can be embodied in several ways.

The cigarette 100 is substantially cylindrical and has a longitudinal axis 101 as shown as an example in FIG.

In the following, the terms "inside" and "outside" are used with respect to the direction perpendicular to the axis 101, i.e., the radial internal / external position within the tobacco. The cigarette 100 includes a telescopic coaxial filter 102 and a cigarette piece 103 connected to the filter 102.

The filter 102 has a first end 102a connected to one end of the tobacco piece 103 and an end 102b opposite to the tobacco piece 103 for placement in the smoker's mouth. ..

Tobacco piece 103 is a well-known type and will not be described in detail.

The tobacco 100 comprises means for connecting the filter 102 to the tobacco piece 103. The connecting means includes, for example, a connecting sleeve 104 described in detail below. The sleeve is preferably wrapped around the filter 102 and the tobacco piece 103 to connect the two together.

Each filter 102 comprises a long shaped inner portion 105 and an outer portion 106 surrounding the portion 105. The inner portion 105 can be formed of a first material, preferably a filter material. In a further embodiment, the inner portion 105 can also be formed in the form of a tube without filter material to form a suction channel. Similarly, the outer portion 106 comprises a second material, preferably a filter material.

In other words, the portion 105 and the portion 106 extend along the filter 102 (from the first end 102a to the second end 102b of the filter 102) so that the portion 105 is located inside the portion 106.

The first and second materials can be the same or different in some respects. For example, the first and second materials can be different in color and / or flavor and / or filtering capacity.

The outer portion 106 is divided along the cutting line "T" into at least two sections (divisions) arranged in order along the axis 101. The first section 106a of the outer portion 106 is located at the first end 102a of the filter and is attached to the tobacco piece 103. The second section 106b of the outer portion 106 is located at the second end 102b of the filter. The second section 106b is the first between a retracted position (FIGS. 2 and 4) close to the first stretch 106a and a stretched position (FIGS. 3 and 5) at a certain distance from the first section 106a. It is slidable along the axis 101 with respect to section 106a. In the embodiments shown in FIGS. 2 to 5, the inner portion 105 of the filter slides the second section 106b of the outer portion 106 from the retracted position to the extended position and from the extended position to the retracted position during movement.

For the embodiments shown in FIGS. 4 and 5, the pieces forming the second contact element 108 are also extended in the first section 106a, again in this section, especially on the inner intermediate sleeve 109. , For example, fixed by a layer 112 of adhesive. Alternatively, instead of a layer of adhesive, the first section 106a and the inner portion 105 can be connected to each other by pressure, embossing or other means.

The connecting sleeve 104 has a fragile line (a wire that is easily torn) 113 that extends around the shaft 101 and forms two parts of the connecting sleeve 104 along the same shaft. The first portion 104a is fixed to the tobacco piece 103. The second portion 104b is fixed to the second section 106b of the outer portion 106 of the filter.

The two parts of the connecting sleeve 104 can be separated by the user moving the second section to the stretched position by applying an axial tensile force to the second section 106b.

In an embodiment (not shown), the fragile line 113 can be placed on the cutting line "T" that forms the boundary between the first section 106a and the second section 106b of the outer portion 106 of the filter. Alternatively, as shown in the accompanying drawings, the fragile line 113 can be placed at a position corresponding to the first section 106a, i.e. between the tobacco piece 103 and the cutting line "T". The distance "D" between the cutting line "T" and the fragile line 113 is preferably greater than the stroke "C", whereby in the extension position, between the second section 106b and the first section 106a, the figure. The gap corresponding to the annular cavity “A” shown in FIG. 3 and 3 is not visible from the outside.

In the second embodiment, the second portion 104b of the sleeve slides on the first section 106a. In other words, the inner portion 105 of the filter constitutes the sliding guide for the second section 106b, and the first section 106a constitutes the sliding guide for the second portion 104b of the connecting sleeve 104.

Preferably, the connecting sleeve 104 comprises a perforated region 114 that forms a high transmittance region appropriately located in the annular cavity "A" formed between the first section 106a and the second section 106b at the stretched position.

To indicate to the user that the stretched position has been reached, the connecting sleeve 104 and / or the outer intermediate sleeve 110 and / or the abutting elements 107, 108 are, if visible, the first or second material and / or the inner intermediate sleeve. It is made of a different color than 109 or of a different material than the first or second material and / or the inner intermediate sleeve 109. As shown in FIG. 3, the color of the inner portion 105 can be different from the intermediate sleeve 110 and, if necessary, the second material visible at the second end 102b.

The filter 102 can also have an internal chamber designed to contain the additives. The chamber is preferably arranged along the tobacco shaft 101. Additives are used to flavor smoke inhaled by consumers (smokers) and may be in the form of capsules, powders, berries, gels, liquids or small pieces of flavored filter material, for example. it can.

Preferably, the additive is of the type whose release is determined by the burning of tobacco or the heat or smoke generated by such burning.

Tobacco 100 can also be provided with a duct leading (accessible) to the chamber for adding additives. Preferably, the duct extends laterally through the filter with respect to the shaft 101 and is preferably linear. In addition, the duct becomes accessible when the filter is in the pulled-out position.

In one feasible embodiment, the internal chamber for at least partially accommodating the additive comprises an annular cavity "A" formed between the first section 106a and the second section 106b at the stretching position. In this case, the connection sleeve 104 may also have an access hole arranged in the annular cavity "A" at the pulled out position.

In use, the user grabs the second stretch 106b of the filter and moves it away from the first stretch 106a, thereby breaking the connecting sleeve 104 at the fragile line 113. The length can be changed by pulling out the second stretch 106b and, if available, the aeration of the tobacco during use.

7, 8a and 8b show two feasible embodiments of the cigarette 100 according to the present invention.

The embodiment of FIG. 7 corresponds to the embodiment of FIG. 4, except that the pieces constituting the second contact element 108 are not extended to the first stretch 106a. The adhesive layer 112 (or other material / process) attaches the inner portion 105 and the outer portion 106, in particular the inner intermediate sleeve 109 and the outer intermediate sleeve 110, directly to each other.

In the embodiments of FIGS. 8a and 8b showing the retracted position and the stretched position, the two contact elements 107, 108 are arranged between the inner portion 105 and the first stretch 106a of the outer portion 106. Further, the second contact element 108 is fixed to the inner portion 105, and the first contact element 107 is fixed to the first stretch 106a. Preferably, the second stretch 106b is attached to the inner portion 105, for example by an adhesive layer 112 (or other material / process). In this case, the inner portion 105 further functions as a guide (guide member) for the second stretch 106b that slides with respect to the first stretch 106a.

In other possible embodiments, one or both of the inner intermediate sleeve 109 and the intermediate sleeve 110 are not provided, and the abutting element adheres directly to the material, preferably to the filter material, or to a tube capable of forming the inner portion 105. Will be done.

Alternatively, instead of the piece of tape, the stopping means may be embodied in different ways, especially the abutment elements 107, 108. For example, the stopping means can be embodied, in particular by applying the contact elements 107, 108 with a material of the form of an adhesive. Alternatively, the stopping means can be embodied in particular by disperse the contact elements 107 and 108 with powder. As another option, the stopping means can be embodied specifically by the contact elements 107, 108 by a layer of ink. Further, the stopping means can be embodied, in particular, the contact elements 107, 108 by relief shapes, that is, embossing. Finally, the stopping means can also be embodied in particular by the abutting elements 107, 108 by sections or folds. As described above, the abutting element can cover the entire circumference of the shaft 101 or only one or more arcs, both in the case of tape pieces and in the case of material addition or shape processing.

With reference to the equipment of FIG. 1, reference numeral 1 indicates an entire machine that produces a filter rod suitable for producing the telescopic coaxial filter 102.

The machine 1 shown in FIG. 1 processes a station 2a for processing a first material suitable for forming the inner portion 105 of the filter and a second material suitable for forming the outer portion 106 of the filter. A station 2b for the purpose is provided. The two stations operate in a known manner. More specifically, the machine 1 is suitable for producing a filter rod from a first material and a second material. When the inner portion 105 is embodied by a tube, part of the machine 1 is replaced with a machine that supplies a continuous tube. An embodiment of the processing station 2a is shown in FIG. 9 as an example. The processing station 2a comprises a bale "M" of the first material, preferably the filter material. Each core 3 is removed from the bail "M" (the word "core" is used to refer to a strip of filter material removed from the bail "M" and is likened to a strip of gauze with reduced lateral dimensions). The wick 3 is supplied along the supply path P1 using a known type of guide device. At least one pneumatic device 4 of a known type configured to laterally spread the wick 3 using airflow and transform the wick into strips of a predetermined width or a continuous ribbon "F" is usually provided.

The processing station 2a also includes a device 5 for processing a material disposed downstream of the pneumatic device 4 and for plasticizing with a fluid that receives and plasticizes the ribbon "F".

After that, the ribbon "F" is supplied to the transfer device 6 that transfers the ribbon "F" toward the molding apparatus 6a. The molding apparatus 6a is configured to receive the ribbon "F" and gather the ribbon "F" around its central axis to obtain the toe 7.

Preferably, the toe 7 is associated with the composite tape 8 and moves above the composite tape 8 itself. The toe 7 is then wrapped in tape 8 to obtain the internal rod 9. More specifically, the inner rod 9 comprises at least a series of unseparated inner portions 105, preferably arranged in a mirror image, and stopping means.

The tape 8 can be wrapped around the toe 7 by the garnish tongue shown in 6b in FIG.

The inner rod 9 thus obtained is transferred towards a portion 1b of a machine 1 configured to complete the formation of the filter rod. More specifically, the filter rod 9 comprises a series of unseparated inner portions 105, preferably mirror-imaged stopping means and outer portions 106.

One feasible embodiment of the portion 1b of the machine 1 and the termination portion of the processing station 2b is shown as an example in FIG.

In portion 1b, the rod 9 reaches at least the adhesive material sticking device 10 configured to stick the strip 11 of the adhesive material along the outer surface of the rod 9. The rod 9 can be supported, preferably by a centering device 12 located downstream of the sticking device 10. In this case, the centering device 12 includes a vertical rib 13 extending parallel to the rod 9 to support the rod 9 between one adhesive strip 11 and the other adhesive strip.

The processing station 2b can be functionally and structurally similar to the station 2a, and as a result, each core is similarly removed from the bail of the second material, preferably the filter material, and then stripped of the second material. Until 14 is formed, the core is fed along the feed path P2 using a known type of guide device towards the station for processing the material. FIG. 15 schematically shows a station 2b that aligns a strip 14 of second material with a continuous rod 9.

More specifically, as shown in FIGS. 15 and 15b, the strip 14 is transferred to the opening 55 of the forming apparatus 6a. An internal rod 9 is also supplied to the opening 55 of the molding apparatus 6a at a position substantially coaxial with its axis. The molding apparatus 6a has a funnel shape that gradually reduces the lateral dimension of the strip 14. More specifically, the strip 14 enters the opening 55 of the device 6a in a direction P2 across the direction P1 of the rod 9 and is dispersed around the rod.

The molding apparatus 6a includes a funnel-shaped body 53 and a tile-shaped tip 54 in which a recess is arranged above the garnish tongs 17.

The body 53 is supplied in a known manner by the airflow schematically indicated by the arrow "A" in FIG. 15b. Due to the decisive action of the airflow from an air source (not shown), the strips 14 are uniformly dispersed around the inner rod 9, and the bond of the inner rod 9 wrapped in the second material is sent to the outlet of the main body 53. Feeding towards, the second material reaches tile 54 and is wound around the inner rod along the garniture tongs 17.

More specifically, in the garnish tongs 17, part 1b of machine 1 preferably receives a continuous tape 15 of paper, the tape being fed along the tongs (tongue) to the second material. It is gradually wound around the wrapped inner rod 9.

In summary, the internal rod 9 follows the supply path P1 into the portion 1b, the strip 14 follows the supply path P2 into the portion 1b, and the tape follows the supply path P3 if there is a tape 15. Enter part 1b at the Garniture Tong 17.

The garnish tongs 17 have an inner channel whose cross section changes along the longitudinal extension of the garnish tongs themselves and approaches itself in the supply direction along the supply path P. The assembly composed of the rods 9 wrapped in the second material and wrapped in the tape 15 extends in the garnish tongs 17 along the supply path P. At the end of the garniture tongs 17, the tape 15 and the strip 14 are wrapped around the rod 9 to form the filter rod 16.

The shape of the transverse cross section of the filter rod 16 is determined by the transverse cross section (at the end) of the channel of the Garniture tongs 17, which is preferably circular or spiral.

The machine 1 also comprises a device 1c configured to form the composite tape 8.

For example, in the first feasible embodiment shown in FIG. 13, device 1c comprises essentially a known type of feeding means configured to pull continuous tape 19 out of roll 20.

A sticking device 21 for sticking the piece 22 to the tape 19 is arranged along the path P4 through which the tape 19 passes. The sticking device 21 cuts the piece 22 from the associated tape 23 drawn from the roll 24 at predetermined intervals, and uses a known type of glue device (not shown) to apply adhesive to one side of the piece. Is configured to form an adhesive layer (not shown) that is applied to and attaches the piece to the tape 19. The pieces 22 are arranged at predetermined intervals "p1" from each other and are configured to constitute the first contact element 107 in each finished cigarette 100. Preferably, the length "Y1" of each piece 22 along the main longitudinal direction of the tape 19 is twice the length "X1" of the abutting element 107.

The piece 22 can be made of any suitable material, for example paper or plastic material, or can be provided with a metal material.

In the cigarettes shown in FIGS. 4 and 5, the tape 19 to which the piece 22 is adhered is configured to form an inner intermediate sleeve 109.

The device 1c comprises an additional supply means of essentially known type configured to pull additional continuous tape 25 from the roll 26.

A further sticking device 27 for sticking the further piece 28 to the further tape 25 is arranged along the path P5 through which the further tape 25 passes. The additional sticking device 27 is to cut the further piece 28 from the associated tape 29 drawn from the roll 30 at predetermined intervals, and to use an adhesive device of a known type (not shown) to further piece the adhesive. It is configured to form an adhesive layer (not shown) that is applied to one surface to attach additional pieces to additional tape 25. Further pieces 28 are arranged at predetermined intervals "p2" from each other and are configured to constitute a second contact element 108 in each completed filtered tobacco 100. Preferably, each additional piece 28 is greater than twice the length "X2" of the abutting element 108, more specifically of the length of the stretch of the abutting element 108 extending to the first stretch 106a. It has a length "Y2" along the main longitudinal direction of the additional tape 25, which is twice the length plus twice the length "X2".

The additional piece 28 may also be made of any suitable material, such as paper or plastic material, or may include a metallic material.

In the cigarettes shown in FIGS. 4 and 5, the additional tape 25 to which the additional piece 28 is adhered is configured to form the outer intermediate sleeve 110.

The tape and the additional tape are connected and stacked parallel to each other so that the piece 22 and the additional piece 28 are placed inward between the two tapes on the supply means and on the downstream side of the additional supply means. The relative positions of the two tapes are adjusted so that the abutting element 107 and the abutting element 108 are located at a distance "L" in each of the finished cigarettes 100. The composite tape 8 is formed by connecting the tape 19 having each piece and the additional tape 25.

For example, in a different embodiment shown in FIG. 10, device 1c comprises a feeding means that pulls continuous tape 19 out of roll 20. Both the sticking device 21 and the further sticking device 27 arranged along the path P4 through which the tape 19 passes are configured in the same manner as in the previous embodiment, but both the piece 22 and the additional piece 28 are put on the tape 19. It is configured to be pasted.

As shown in detail in FIG. 11, attaching the pieces 22 to the tape 19 involves applying an adhesive 31 to form an adhesive layer that permanently attaches each piece 22 to the tape 19. Preferably, the adhesive layer 31 covers the entire surface of the piece 22. Attaching the additional piece 28 to the tape 19 involves applying the adhesive 32 to a limited portion of the surface of the additional piece, preferably in the center of the additional piece. The adhesive 32 forms an adhesive layer 112 between the inner portion 105 and the outer portion 106.

Reference numeral 33 indicates an adhesive device that is suitable for connecting to an additional tape 25 and is configured to apply a layer 34 of adhesive to the surface of the additional piece 28. The layer 34 of adhesive is suitable for permanently attaching each additional piece 28 to the additional tape 25. Preferably, the adhesive layer 34 covers the entire surface of the additional piece 28.

The additional tape 25 is pulled out of the roll 26 and affixed parallel to the tape 19 so that the piece 22 and the additional piece 28 are placed inward between the two tapes. The composite tape 8 is constructed by connecting the tape 19 and the further tape 25.

In both cases of FIGS. 10 and 13, changing the position of the piece and the additional piece, setting the piece and the additional piece separately on demand, and / or spacing the piece and the additional piece. The pasting devices 21 and 27 are independent of each other and can be adjusted independently so that they can be changed.

In the embodiments described above, the inner rod 9 with the toe 7 and the composite tape 8 has a continuous inner portion 105 that has an inner intermediate sleeve 109, preferably a mirror image, and an outer side. The outer intermediate sleeve 110 of the portion 106 is provided.

FIG. 12 schematically shows a partial cross section in the longitudinal direction of the inner rod 9 in which the composite tape 8 is preferably obtained from the device 1c of FIGS. 10 and 11. The rod 9 of FIG. 12 is suitable for producing the tobacco 100 according to the embodiment shown in FIGS. 4 and 5. FIG. 12 also shows subsequent cutting and incision operations in the form of filter pieces at different stages.

Tobacco, machines and methods according to the present invention have great advantages. The inner portion 105 constitutes a coaxial core portion that functions as a guide for telescopic movement that gives more firm mechanical rigidity when in the stretched position. Also, a stopping means can be inserted directly between the inner and outer portions, especially when winding two portions between the two portions. This surface allows the formation of a filter with a very smooth outer surface. Thus, the absence of irregularities on the outer surface makes it easier to handle tobacco during various production stages, especially during packaging, in addition to its obvious aesthetic advantages.

The two coaxial parts allow the filter's filtering capacity and physical properties (eg, breathability and pressure drop) to be calibrated very accurately in the design stage acting on the inner or outer parts. For example, two different materials or the same material with different specifications can be used. Preferably, two types of cellulose acetate are used. One of the two types of cellulose acetate is a material with few filaments but thick, as a first material, i.e. forming the inner portion 105, and the other is a material with more filaments, thinner, as a second material, i.e. outer. The material that forms the portion 106.

According to the present invention, the tobacco can be customized by adjusting the ventilation. When the outer portion 106 is in the retracted position, the air permeability can be increased, and when the outer portion 106 is in the stretched position, the air permeability can be decreased. In particular, it is possible to form a high transmittance region in the connection sleeve 104 by the perforation region 114 using laser perforation, electrostatic microperforation technology, or plasma microperforation technology. At the stretched position, the perforated region 114 moves to the annular cavity "A". In addition or / or, if the outer portion 106 is in the stretched position, the uncoated porous paper can be concealed and placed.

It is also possible to access the internal cavity (through an opening that opens when the outer portion 106 is in the stretched position) for inserting additives (eg, seasoning capsules or berries).

In addition, changes in tobacco properties can be manifested by colors, letters, or marks on uncoated paper, in addition to obvious changes in shape. The outer intermediate sleeve 110 can also be colored.

Finally, compared to non-stretchable tobacco, the tobacco according to the present invention can be packaged in a shorter packaging box, which can clearly save packaging material, freight capacity and the like.
