Description

Cigarette wrapping method, cigarette making machine and cigarette wrapping paper

The present invention relates to a method for manufacturing cigarette paper provided with low fire spreadability, a manufacturing machine for the same, and cigarette paper.

Recently, low-flammability wrapping paper used for cigarettes is known, and a combustion inhibitor is applied to a predetermined area of the wrapping paper. In general, a cigarette paper (wrapping paper) is added with a combustion aid in the paper making process. As the auxiliary combustor, organic acid salts such as sodium citrate and potassium citrate are provided, and these auxiliary combustors are used as a combustion rate regulator in order to promote combustion.

The web to which the combustion aid is added in the paper making process is then coated with a flame retardant in a predetermined area in a predetermined area. In this case, since the auxiliary combustor is added over the entire area of the web, many combustion inhibitors are required. Moreover, since the method of adding a combustion aid in advance in the paper making process in this way adds a combustion inhibitor in a subsequent process, the amount of both cannot be adjusted simultaneously.

On the other hand, as a method of adding a combustion inhibitor and an auxiliary combustor to a wrapper at an appropriate ratio, a technique of adding a mixture of a combustion inhibitor and a combustion accelerator is disclosed (see, for example, Patent Document 1). Specifically, Patent Document 1 is treated with an air permeability reducing substance (starch, cellulose), a combustion retarding substance (ammonium phosphate), and a combustion accelerating substance (alkali metal salt or alkaline earth metal salt of carboxylic acid). It is intended to keep the smoking interval constant.

In the present invention, since the cigarette paper is manufactured by the above-described manufacturing method, it is possible to manufacture a low-fire-rolling paper with stable quality.

It is the schematic of the manufacturing machine of the cigarette paper based on this invention. It is the schematic of the web W which apply | coated the combustion inhibitor and the auxiliary combustion agent. It is the schematic of another web W which apply | coated the combustion inhibitor and the auxiliary combustion agent. It is the schematic of the manufacturing machine of another cigarette paper based on this invention.

As shown in FIG. 1, a cigarette paper making machine 1 according to the present invention includes a travel route 2 that travels a paper web W along an arrow in FIG. 1. A first coating device 3, a second coating device 5, and a drying device 4 are disposed in the traveling path 2 in order from the upstream side.

The first coating device 3 is for partially coating the web W with the combustion inhibitor 6 (see FIGS. 2 and 3). Specifically, the combustion inhibitor 6 is applied to a plurality of locations so as to cross in the width direction of the web W at a certain interval with respect to the longitudinal direction of the web W. That is, the combustion inhibitor 6 is applied to the web W in a band shape. This application is performed by a known method using a press roll 7 or a gravure roll 8 included in the first application apparatus 3.

The second coating device 5 is located downstream of the first coating device 3 and is used to apply the combustion aid 26 (see FIGS. 2 and 3) to the web W that has passed through the first coating device 3. is there. As the conventional auxiliary combustion agent 26, an organic acid salt such as potassium citrate or other substances that promote combustion can be used. As shown in FIG.2 and FIG.3, the auxiliary combustion agent 26 is apply | coated to the surface on the opposite side to the surface where the combustion inhibitor 6 was apply | coated. For this reason, the auxiliary combustion agent 26 does not affect the combustion suppressing agent 6. That is, since the combustion inhibitor 6 is water-soluble, it can be prevented that the combustion inhibitor 6 is dissolved by the auxiliary combustor 26. In addition, when a powdery combustion aid is used as the combustion aid 26, it may be applied to the same surface as the surface on which the combustion inhibitor 6 is applied.

Specifically, the second coating device 5 applies the auxiliary fuel 26 supplied from the press roll 9, the gravure roll 10, and further from the nozzle 11 in the same manner as the first coating device 3. In order to receive it with the gravure roll 10, it has a furnisher roll 12 that is in rolling contact with the gravure roll 10. The auxiliary combustion agent 26 supplied from the nozzle 11 is applied to the outer peripheral surface of the gravure roll 10 and applied (transferred) to the web W running between the gravure roll 10 and the press roll 9. Thus, since a combustion aid is indirectly applied through the gravure roll 10, the combustion support agent can be efficiently applied using a transport roll for transporting the web W. When the auxiliary combustion agent 26 is applied by the gravure roll 10, the excessive auxiliary combustion agent 26 is scraped off by the doctor blade 27 and removed from the gravure roll 10. The removed auxiliary combustor 26 is recovered by a recovery chute 28 that covers the region from the gravure roll 10 to the finisher roll 12 from below and is returned to the tank 14 described later (arrow F in FIG. 1).

The drying device 4 is located downstream of the second coating device 5 and is for drying the web W coated with the combustion inhibitor and the auxiliary combustion agent. Specifically, the drying apparatus 4 includes a plurality of drying furnaces (not shown), and the web W is heated and dried by passing through the drying furnace. As shown in FIG. 4, the drying device 4 may be located upstream of the second coating device 5. As described above, even if the drying device 4 is arranged at any position upstream or downstream of the second coating device 5, the object of applying an appropriate amount of the auxiliary combustion agent 26 can be achieved.

A case where cigarette paper is manufactured using the manufacturing machine 1 as described above will be described with reference to FIG. First, the web W is sent out from the original fabric 13 around which the paper web W is wound so as to travel along the travel path 2 in the direction of arrow A. And the combustion inhibitor 6 is apply | coated by the 1st coating device 3 for every predetermined space | interval. Through such a first coating process, the web W further travels in the direction of arrow B and passes through the second coating device 5. In the second coating apparatus, the auxiliary combustion agent 26 is applied to the opposite surface of the web W to which the combustion inhibitor 6 is applied. Thus, in the second coating step, the auxiliary combustor 26 is applied to the opposite side of the web W to the side where the combustion inhibitor 6 is applied. Will not affect. The web W further travels in the direction of arrow C and passes through the drying device 4. In the drying device 4, the web W is heated and dried. Through such a drying process, the web W travels along the traveling path 2 in the direction of arrow D, and passes through a heel stretcher 17 described later.

Thus, in the manufacturing method of the cigarette paper according to the present invention, the coating process is performed using the second coating apparatus 5 on the web W before passing through the drying apparatus 4 for performing the drying process, and the auxiliary agent is added. 26 is applied. That is, prior to the drying step, both the auxiliary combustor 26 and the combustion inhibitor 6 are applied to the web W.

The auxiliary combustion agent 26 applied in the second application step, that is, the auxiliary combustion agent 26 to be supplied to the second application device 5 is actually filled in the tank 14 as an aqueous solution. Between this tank 14 and the 2nd coating device 5, the pump 15 for sending a combustion aid from the tank 14 to the 2nd coating device 5 is arrange | positioned. The remaining amount, that is, the consumption amount of the auxiliary combustion agent 26 in the tank 14 is measured by the control device 16 including the monitoring function. Further, the delivery amount by the pump 15 is adjusted by the control device 16 including the adjusting function of the pump 15. In addition, you may provide the apparatus which has these monitoring functions and adjustment functions as a separate body.

The controller 16 is provided with a function of monitoring the application amount of the auxiliary combustion agent per unit area on the web W, and even if the auxiliary combustion agent is selectively applied to the entire surface or a partial region of the web W by using this function. Good. In this case, for example, the amount of the auxiliary combustor applied is changed by changing the cell shape (uneven shape of the peripheral surface) of the gravure roll 10 or moving the press roll 9 up and down. The movement of the press roll 9 can be performed using the actuator 29, for example. If this actuator 29 is connected to the control device 16, the application amount of the auxiliary combustion agent 26 can be changed using the control device.

If the control device is used in this way, for example, as shown in FIG. 2, the auxiliary combustor 26 can be applied with a concentration gradient (shading). That is, in the example of FIG. 2, the combustion inhibitor 6 applied to one surface of the paper web W and the auxiliary agent 26 applied to the other surface of the web W with different thicknesses are provided. . Alternatively, it is applied so that the concentration of components (for example, sodium citrate and potassium citrate described above) contained in the auxiliary combustion agent 26 varies along the longitudinal direction of the web W.

Alternatively, as shown in FIG. 3, it is possible not to apply the auxiliary combustion agent 26 to the back surface of the portion where the combustion inhibitor 6 is applied. That is, in the example of FIG. 3, the combustion inhibitor 6 partially applied to one surface of the paper web W and the other surface of the web W other than the region where the combustion inhibitor 6 is applied. And an auxiliary combustion agent 26 applied to a region corresponding to the region. The manufacturing method according to the present invention described above can be applied to various application forms of the auxiliary combustor 26 as shown in FIGS. For this reason, it is possible to apply an appropriate auxiliary combustion agent 26 according to the material and air permeability of the web W.

The web W that has passed through the drying device 4 travels along the traveling path 2 in the direction of arrow D as described above, and passes through the kneading device 17. The crease-stretching device 17 has a damping part 18, a crease-stretching part 19, and a drying part 20. The damping unit 18 includes a gravure roll 21 and a pinch roll 22, and the gravure roll 21 applies water to the web W. In the heel-stretching section 19, the heel-stretching roll 23 expands the web W in the lateral direction by the tension applied to the roll. Then, the web W is dried using the drying unit 20 in an expanded state. The drying unit 20 has a heated heater roll 24 and a press roll 25 that is in contact with the heater roll 24. When passing between the

rolls

24 and 25, the web W is heated and dried by the heater roll 24 while being surely flattened by the press roll 25.

In the present invention, the auxiliary combustor that has been conventionally added in the papermaking process is applied with a combustion inhibitor of the web W using an application device. By doing so, it is possible to apply an appropriate amount of an auxiliary combustor according to the material of the various webs W, etc., and it is possible to apply while considering the balance with the application amount with the combustion inhibitor. By making the application amount appropriate, it is possible to realize a reduction in the application amount as compared with the conventional case.

On the other hand, the web W that has undergone the curl-stretching process is manufactured as a cigarette wrapping paper through a slit forming process in which the web W travels in the direction of arrow E, forms a slit in the web W, and cuts to a predetermined width. . Thus, if the above-described web W is used, a low-flammability wrapping paper with stable quality can be manufactured. In addition, the production method of the present invention is particularly effective for the production of a small quantity and a variety of lots.
