Description

  The present invention relates to a method for producing a cigarette with a filter obtained by connecting a cigarette and a filter by chip paper and having a double wrapping material structure on a part of the outer periphery of the cigarette.

  The manufacturing method of this kind of filter-attached cigarette is disclosed by the following patent document 1, for example. The double wrapping material structure obtained by the manufacturing method of Patent Document 1 includes a wrapping material of cigarette itself and an inner patch partially attached to the inner surface of the wrapping material at a predetermined position. Such an inner patch helps to add a unique function to the filtered cigarette. In the case of Patent Document 1, for example, the inner patch is formed from a paper containing activated carbon and menthol, and the menthol flavor is added to the cigarette with a filter as a unique function. In addition, inner patch activated carbon is used to stably hold the menthol in the paper.

Japan Special Table 2007-524418

  According to the manufacturing method of Patent Document 1, the inner patch described above is pasted at a certain interval along the longitudinal direction of the web in the process in which the web forming the packaging material travels toward the cigarette manufacturing apparatus. Attached. A cigarette manufacturing apparatus manufactures a cigarette at high speed, and the running speed of the web supplied toward the cigarette manufacturing apparatus is very high. For example, if a cigarette manufacturing apparatus manufactures 4000 cigarettes per minute and the length of each cigarette is 54 mm, the running speed of the web is 216 m / min (= (54 mm × 4000) / 1000). Also reach. In this way, it is very difficult to accurately apply the inner patch to a desired position of the web that is running at high speed.

  In addition, the web is allowed to stretch properly, which allows the web to run at high speed, while avoiding breakage of the web even if tension is applied to the web when the bobbin is fed out. And Since the elongation of the web is greatly affected by the strength of the tension and the ambient humidity, it becomes more difficult to accurately apply the inner patch. As a result, even if a cigarette with a filter is manufactured using a web with an inner patch affixed, variations in the position of the inner patch are inevitable, and the quality of the cigarette with a filter is within an acceptable range. It becomes difficult.

  The objective of this invention is providing the manufacturing method which can stabilize the quality of the cigarette with a filter in manufacturing the cigarette with a filter which has the above-mentioned double packaging material structure.

The above object is achieved by a method for producing a cigarette with a filter according to the present invention, and the production method comprises:
Forming a cigarette rod having a length twice that of the cigarette in the filter cigarette, wherein the cigarette rod includes a packaging material and a smokable filler filling the packaging material;
A winding step of winding at least one outer wrapping material around the cigarette rod;
A first cutting step of equally cutting the cigarette rod around which the outer wrapping material is wound to form two cigarettes each having a double-structured wrapping material;
An inversion step of inverting each of the two cigarettes;
Placing a filter plug having a length twice that of the filter between the two cigarettes after inversion, and attaching the two cigarettes after the inversion to the filter plug;
A double chip paper having a width twice that of the chip paper as viewed in the longitudinal direction of the cigarette with filter is wound around the two cigarettes and the filter plug after inversion, and has a length twice that of the cigarette with filter. Forming a cigarette with a double filter;
A second cutting step of cutting the cigarette with a double filter into individual cigarettes with a filter.

  According to the manufacturing method described above, the double wrapping material structure of a cigarette with a filter is provided by wrapping the outer wrapping material around the outer periphery of the cigarette rod. Part. Therefore, when the outer wrapping material is wound around the outer circumference of the cigarette rod, the wrapping paper is released from the tension applied in the axial direction of the cigarette rod. Therefore, the elongation of the wrapping paper due to such tension does not adversely affect the winding of the outer packaging material.

As a result, according to the manufacturing method of the present invention, the outer wrapping material can be wound around the desired position of the cigarette rod, and the quality of the filled tash galette having the double wrapping material structure can be stabilized.
Other advantages of the present invention will be apparent from the accompanying drawings and the description of embodiments below.

Referring to FIG. 1, the manufacturing system for carrying out the manufacturing method of the present invention includes a filler supply device 10, a cigarette manufacturing device 12, and a filter mounting device called a filter chip attachment 14, all of which are known. However, it will be briefly described below.
FIG. 2 shows the filler supply device 10 and the cigarette manufacturing device 12 more specifically. The filler supply device 10 once receives a smokable filler in the receiver 16. Here, the filler includes cigarettes, and the cigarettes are a mixture of ticks obtained by cutting tobacco leaf pieces, middle bones (reeds), regenerated cigarettes, and the like. The filler in the receiver 16 is adsorbed by an endless tobacco band 18, and a layer 20 of filler is formed on the tobacco band 18. Thereafter, the filler layer 20 is supplied toward the cigarette manufacturing apparatus 12 as the cigarette band 18 travels.

  The cigarette manufacturing apparatus 12 includes an endless garniture tape 22 that receives a web W serving as a cigarette wrapping paper. On the other hand, the filler layer 20 is received by the web W on the garniture tape 22 from the tobacco band 18 through the shoe 24. The filler layer 20 travels with the web W as the garniture tape 22 travels. In such a running process of the web W, the web W takes the help of the garniture tape 22 and wraps the filler layer 20 in a rod shape. As a result, the tobacco rod TR is continuously formed. In order to form the tobacco rod TR here, in addition to a forming bed (not shown) for guiding the travel of the garniture tape 22, a tong 26, a former 28, a dryer 30 and the like are used.

Thereafter, the cigarette rod TR passes through the cutter 32 and is then cut into the cigarette rod CR or cigarette C. The cigarette rod CR has twice the length of the cigarette C.
Here, if the cigarette manufacturing apparatus 12 and the filter chip attachment 14 are directly connected, the filter chip attachment 14 sequentially receives the cigarette rod CR or cigarette C from the cigarette manufacturing apparatus 12, and then receives them as shown in FIG. The cigarette rod CR or cigarette C is conveyed in a direction perpendicular to the axis thereof. Specifically, the filter chip attachment 14 includes a drum row (not shown) that defines a conveyance path for the cigarette rod CR or the cigarette C, and this drum row is formed by a plurality of grooved conveyance drums. It is connected along the transport path. In addition, the conveyance drum located at the start end of the drum row is formed as a catcher drum.

FIG. 3 shows a flow of processing of the cigarette rod CR in the filter chip attachment 14 when the filter chip attachment 14 receives the cigarette rod CR. As apparent from FIG. 3, the cigarette rod CR is first cut into equal parts and formed into two cigarettes C. Thereafter, the two cigarettes C are separated from each other in the axial direction, and a predetermined interval is secured between the two cigarettes C.
Next, the filter plug FP is disposed between the two cigarettes C, and the two cigarettes C are brought into close contact with both ends of the filter plug FR (contacting process of the cigarette to the filter plug). Thereafter, the filter plug FR and the two cigarettes C are connected through winding of the double chip paper DTP to form a cigarette with a double filter (a process of forming a cigarette with a double filter). Furthermore, the cigarette with a double filter is cut equally to form two cigarettes with a filter FC (second cutting step).

On the other hand, FIG. 4 shows a flow of processing of the cigarette C in the filter chip attachment 14 when the filter chip attachment 14 receives the cigarette C. As is apparent from FIG. 4, first, the cigarettes C are arranged on the transport path so that the cigarettes C are arranged in a zigzag along the transport path. Thereafter, the two cigarettes C adjacent in the transport direction are aligned so that the cigarettes C are positioned on the same line. Thereafter, the filter-attached cigarette FC is formed in the same procedure as in FIG.
As shown in FIG. 1, the above-described manufacturing system further includes a packaging material adding device 34 for providing a double packaging material structure on a part of the outer periphery of the cigarette C in the cigarette FC with a filter, and this packaging material adding device is a cigarette. It is arranged between the manufacturing device 12 and the filter chip attachment 14.

FIG. 5 shows in detail the packaging material adding apparatus 34 according to the first embodiment of the present invention.
The packaging material adding device 34 includes a drum row 36 similar to the drum row of the filter chip attachment described above, and the drum row 36 includes a plurality of grooved transfer drums. These transfer drums include a catcher drum 38, a first transfer drum 40, an outer packing material attaching drum 42, an outer packing material winding drum 44, a cutting drum 46, a reversing drum 48, a second transfer drum 50, and a third transfer drum. It is called a transfer drum 52 and defines a transfer path for the cigarette rod CR.

  On the other hand, a receiving drum 54 is disposed in the vicinity of the pasting drum 42, and a knife drum 56 is adjacent to the receiving drum 54. The knife drum 56 has a number of knives on its outer peripheral surface, and these knives are arranged at equal intervals in the circumferential direction of the knife drum 56. An outer web OW forming an outer wrapping material is guided to the receiving drum 54, and the outer web OW is adsorbed to the outer peripheral surface of the receiving drum 54 by suction. For example, the receiving drum 54 is connected to the web roll WR via the sending path 58, and the outer web OW is sent from the web roll WR to the receiving drum 54 along the sending path 58. The delivery path 58 is defined by a number of guide rollers.

  A feed roller unit 60 is disposed in the feed path 58, and the feed roller unit 60 feeds the outer web OW from the web roll WR at a constant speed. Further, an adhesive applicator 62 is disposed in the delivery path 58, and the applicator 62 is positioned downstream of the foot roller unit 60. The applicator 62 includes a pan 64 storing an adhesive, a gravure roll 66 and a transfer roller 68, and the adhesive in the pan 64 is applied to the inner surface of the outer web OW via the gravure roll 66 and the transfer roller 68.

  The above-described adhesive application periodically forms an adhesive band B on the outer web OW, and these bands B are distributed along the longitudinal direction of the outer web OW with a predetermined pitch P, as is apparent from FIG. The For example, the pitch P is longer than the circumference of the cigarette C by a predetermined length. In the present embodiment, the width Ww of the outer web OW is 20 mm. The band B has a length Lb along the width direction of the outer web OW, and the length Lb is shorter than the width Ww of the outer web OW. Therefore, margins are left between the band B and both side edges of the outer web OW, for example, the margin is 0.1 mm. Furthermore, the band B has a width Wb along the longitudinal direction of the outer web OW, and this width Wb is, for example, 6.0 mm.

  The receiving drum 54 and the knife drum 56 described above cooperate with each other to periodically cut the outer web OW in which the band B is formed at intervals equal to the pitch P, and the individual outer packaging materials on the receiving drum 54. Form. A cutting line on which the outer web OW is to be cut is indicated by a one-dot chain line in FIG. Therefore, when the outer wrapping material is formed, the outer wrapping material has an adhesive stripe on its head and tail as viewed in the direction of delivery of the outer web OW. These adhesive stripes are formed by cutting the band B. As is apparent from FIG. 6, the tail adhesive stripe has a wider width than the adhesive stripe of the head. Such an outer wrapping material is affixed like a flag to the cigarette rod CR transported on the transport path described above through the adhesive stripe of the head.

  Specifically, FIG. 7 shows a flow of processing of the cigarette rod CR in the transfer path. First, the transfer path receives the cigarette rod CR from the cigarette manufacturing apparatus 12 by the catcher drum 38, and the received cigarette rod CR is transferred to the attaching drum 42 through the first transfer drum 40. Here, when the packaging material adding apparatus 34 of this embodiment is applied to the cigarette manufacturing apparatus 12 that manufactures the cigarette C, the cigarette manufacturing apparatus 12 is modified to manufacture the cigarette rod CR instead of the cigarette C. For example, in this adaptation, the cutting timing of the cutter 32 in the cigarette manufacturing machine 12 is changed.

  When the cigarette rod CR on the affixing drum 42 passes through the receiving drum 54, the head of the leading outer wrapping material on the receiving drum 54 contacts the outer periphery of the cigarette rod CR via the adhesive stripe. Material X is affixed like a flag at the center of the cigarette rod CR (before the winding process). Here, on the first transfer drum 40, the center position of the cigarette rod CR is positioned in consideration of the attachment of the outer wrapping material X, and by this positioning, the outer wrapping material X is accurately attached to the center of the cigarette rod CR. It becomes possible to attach.

  Thereafter, the cigarette rod CR with the outer wrapping material X attached thereto is transferred from the attaching drum 42 to the winding drum 44. The winding drum 44 includes a rolling plate 70 (see FIG. 5), and a rolling passage is defined between the rolling plate 70 and the outer periphery of the winding drum 44. When the cigarette rod CR passes through the rolling passage, the cigarette rod CR rotates around its axis, and with this rotation, the outer wrapping material X is wound over the entire circumference of the cigarette rod CR (after the winding process). At this time, the tail of the outer wrapping material X is bonded to the outer surface of the head of the outer wrapping material X via the adhesive strip, and forms a seam together with the head.

  Thereafter, the cigarette rod CR is transferred from the winding drum 44 to the cutting drum 46, and the cutting drum 46 is provided with a rotary knife 72. Therefore, when the cigarette rod CR on the cutting drum 46 passes through the rotary knife 72, it is equally divided with the outer wrapping material X at the center thereof, and two pieces having a double wrapping structure are formed by cutting here. Cigarette C is formed (first cutting step). The double wrapping material structure is disposed at one end of the cigarette C and includes a cigarette C's own wrapping paper and an outer wrapping material Y. The outer wrapping material Y is formed from a half of the outer wrapping material X.

  Next, the two cigarettes C are transferred from the cutting drum 46 to the reversing drum 48, where the two cigarettes C are reversed by 180 ° (reversing step). As a result, the postures of the two cigarettes C are changed from a state where the one end portions having the double wrapping material structure face each other to a state where the one end portions are opposite to each other. To enable such reversal of cigarette C, reversal drum 48 includes a number of holders that receive cigarette C. These holders have a rotation axis extending in the radial direction of the reversing drum 48, and are rotated around the rotation axis in the process of moving in the circumferential direction of the reversing drum 48.

  Thereafter, the two cigarettes C after the reversal are transferred from the reversal drum 48 via the second and third transfer drums 50 and 52 toward the filter chip attachment 14 described above. Here, the two cigarettes C reversed to each other on the second transfer drum 50 are brought into close contact with each other so as to form one cigarette rod CR, and thereafter, the second transfer drum 50 to the third transfer drum. Change to 52. Further, the third transfer drum 52 is arranged so as to make rolling contact with the catcher drum of the filter chip attachment 14, whereby the transfer of the two cigarettes C from the third transfer drum 52 to the catcher drum, that is, in the present embodiment. The packaging material adding device 34 and the filter chip attachment 14 can be connected.

  Further, when the filter chip attachment 14 is of a type that is applied to the cigarette rod CR, the rotary knife that equally cuts the cigarette rod CR is removed from the corresponding transport drum. Therefore, the two cigarettes C transferred from the packaging material adding device 34 to the filter chip attachment 14 were obtained by cutting the cigarette rod CR in the filter chip attachment 14 as apparent from FIG. It is processed in the same way as two cigarettes C. As a result, a cigarette FC with a filter having a double packaging structure is formed.

  On the other hand, when the filter chip attachment 14 is of a type that receives individual cigarettes C from the cigarette manufacturing apparatus 12, the second transfer drum 50 described above is replaced with a grading drum. The grading drum receives two cigarettes C from the reversing drum 48 as shown in FIG. 8, and shifts these cigarettes C in the transport direction. In this way, the cigarette C transferred from the grading drum to the filter chip attachment 14 is processed in the same manner as the cigarette C transferred directly from the cigarette manufacturing apparatus 12, as is apparent from FIG. A cigarette FC with a filter having a double packaging structure is formed.

  The manufacturing method of 1st Embodiment mentioned above manufactures the cigarette FC with a filter as shown in FIG. 9, and this cigarette FC with a filter has a double wrapping material structure in the front-end | tip part of the cigarette C. FIG. In the case of the first embodiment, as apparent from FIG. 10, the double wrapping material structure has a ring shape over the entire circumference of the cigarette C and has a width of 10 mm from the tip of the cigarette C.

  If the outer wrapping Y that forms part of the double wrapping structure has specific properties, the filtered cigarette FC manufactured by the manufacturing method of the present invention is unique based on the properties of the outer wrapping Y. Demonstrate the function. Further, the outer wrapping material Y is not bonded to the outer periphery of the cigarette C, and only the head and tail are bonded to each other, so when wrapping the outer wrapping material X around the outer periphery of the cigarette rod CR, The amount of adhesive required is minimized, and the adverse effects of the adhesive on the unique functions described above can be effectively suppressed.

The manufacturing method of the present invention provides a double wrapping material structure on a part of the outer periphery of the cigarette C by attaching and winding the outer wrapping material X around the cigarette rod CR. Therefore, when the outer wrapping material X is attached and wound, the wrapping paper of the cigarette rod CR is already released from the tension applied in the axial direction of the cigarette rod CR. Therefore, in the state of the cigarette rod CR, elongation due to tension does not occur in the wrapping paper of the cigarette rod CR, so that the outer wrapping material X can be accurately wound around a desired position of the cigarette rod CR. As a result, according to the manufacturing method of the present invention, it is possible to manufacture a cigarette FC with a filter having a double packaging structure with stable quality.
The double wrapping material structure of the first embodiment has a ring shape as described above, but may have a semicircular shape and an arc shape as shown in FIGS.

FIG. 13 shows a cigarette FC with a filter having a double packaging structure manufactured by the manufacturing method of the second embodiment. In this case, the double wrapping material structure of the cigarette FC with filter is arranged not at the tip of the cigarette C but at a predetermined distance from the tip of the cigarette C.
In order to manufacture such a cigarette FC with a filter according to the second embodiment, the above-described packaging material adding device 34 includes, for example, two delivery paths 58 for the outer web OW. In this case, as shown in FIG. 14, the two delivery paths 58 send out the outer webs OW toward the receiving drum 54, respectively, and in the course of sending out these outer webs OW, the band B of the adhesive described above is provided on each outer web OW. It is formed similarly. Further, for example, an interval D is secured between the outer webs OW on the two delivery paths 58.

  In the manufacturing method of the second embodiment described above, the outer wrapping material X is formed from each outer web OW, the outer wrapping material X is used as the outer wrapping material Y, and there is an interval D on the outer periphery of one cigarette rod CR. Then, two cigarettes FC with a filter shown in FIG. 13 are formed from the cigarette rod CR. As is apparent from the above description, the double wrapping material structure of the cigarette FC with filter is arranged with a distance D / 2 from the tip of the cigarette C.

In the case of the second embodiment, a common applicator 62 and a cutting unit including a receiving drum 54 and a knife drum 56 can be used for applying an adhesive to each outer web OW and cutting each outer web OW. An applicator and a cutting unit may be prepared in the outer web OW.
Even in the case of the second embodiment, the double wrapping material structure only needs to be disposed on at least a part of the entire circumference of the cigarette C as shown in FIGS. 11 and 12. Furthermore, the cigarette with a filter of the present invention may include two or more double wrapping material structures that are separated from each other in the axial direction of the cigarette.
