Description

Cigarette wrapping paper manufacturing method and machine

The present invention relates to a method for manufacturing cigarette wrapping paper that imparts low fire spreadability to a cigarette and a manufacturing machine therefor.

In recent years, low-flammability wrapping paper used for cigarettes is known. The low-rollability wrapping paper having a fragrance function is formed by cutting a paper web to which a fragrance is added, for example. This fragrance is added at the paper making stage. Thereafter, a combustion inhibitor is applied at a predetermined interval in the longitudinal direction of the web in order to impart low spreadability to the paper web to which the fragrance has been added. This combustion inhibitor is generally applied to paper in a state dissolved or suspended in water. Since a large amount of water is used at this time, a drying process is performed using a great amount of heat energy in order to dry the water. By this drying step, the above-described fragrance may be volatilized.

On the other hand, low-fire-spreading webs are described in Patent Documents 1 and 2. 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), and the entire smoking interval. Is intended to be constant. Patent Document 2 includes a base sheet having a seam adhesive containing a first flavoring agent and a plurality of bands provided in a pattern on the main surface, each band having at least two layers. The two layers include a bottom layer applied to the major surface of the base sheet and a top layer applied over the bottom layer, at least one layer comprising a packaging material incorporating a second flavoring agent. Are listed.

However, in both Patent Documents 1 and 2, volatilization due to a large amount of heat energy in the drying process as described above is unavoidable, and furthermore, an accurate amount of perfume can be selectively added to any position of the web. Have difficulty.

The present invention prevents the fragrance from being volatilized in the wrapping paper manufacturing process even if the web includes a drying process, and applies an accurate amount of the fragrance to a predetermined position of the web. Therefore, it is an object of the present invention to provide a method for manufacturing cigarette wrapping paper and a machine for manufacturing the cigarette wrapping paper which can apply any fragrance to the web.

In the present invention, a paper web is run along a running path, a first application step of applying a combustion inhibitor to the web, and heating and drying the web coated with the combustion inhibitor. The cigarette wrapping paper manufacturing method provided with the drying process of the above WHEREIN: The manufacturing method of cigarette wrapping paper provided with the 2nd application | coating process which apply | coats a fragrance | flavor to the said web after the said drying process is provided.

Preferably, the second application step includes a second drying step in which a heating temperature is lower than that of the first drying step.

Preferably, in the second application step, the fragrance is applied to the opposite side of the web to the side where the combustion inhibitor is applied.
Preferably, in the second application step, the fragrance is once applied to a roll for conveying the web, and the fragrance is applied to the web through the roll.

A cigarette wrapping paper manufacturing machine comprising a second coating device for coating

According to the present invention, the perfume is applied to the web that has passed through the first drying device that performs the first drying step, using the second coating device. That is, since the application of the fragrance to the web is performed after the first drying step, it is possible to prevent the fragrance from being volatilized in the first drying step.

Further, according to the present invention, after the second coating step, the second drying step for heating the web and stretching it, for example, is included, and the heating temperature in the second drying step is the first temperature. Lower than the heating temperature in the drying step. This is based on the fact that the heating temperature in the first drying step is a temperature at which the fragrance is volatilized, and the heating temperature in the second drying step is a temperature at which the fragrance is not volatilized. That is, since the first drying step dries the web on which the combustion inhibitor is applied, the heating temperature is so high that the fragrance is volatilized. On the other hand, a 2nd drying process is a grade which extends the wrinkle of the web after apply | coating a fragrance | flavor, for example, and the heating temperature is a low temperature which a fragrance | flavor does not volatilize. Therefore, no fragrance is volatilized.

Further, in the second application step, the fragrance is applied to the opposite side of the web to which the combustion inhibitor is applied, so that the fragrance does not affect the combustion inhibitor.
Moreover, since a fragrance | flavor is apply | coated indirectly via a roll, a fragrance | flavor can be efficiently apply | coated using the conveyance roll for conveying a web.
Further, according to the present invention, since the amount of fragrance applied is monitored in the second application step, the application of the fragrance to the web can be controlled using the result of this monitoring.

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. It is the schematic of the web W which apply | coated the fragrance | flavor.

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 first drying device 4, and a second coating device 5 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 FIG. 2). 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 first drying device 4 is located downstream of the first coating device 3 and is for drying the web W coated with the combustion inhibitor. Specifically, the first 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.

The second coating device 5 is located downstream of the first drying device 4 and is used to apply the fragrance 26 (see FIG. 3) to the web W that has passed through the first drying device 4. As the fragrance 26, various fragrances can be used. As shown in FIG. 3, the fragrance | flavor 26 is apply | coated to the surface on the opposite side to the surface where the combustion inhibitor 6 was apply | coated. Thus, since the fragrance | flavor 26 is apply | coated to the opposite side with respect to the side by which the combustion inhibitor 6 of the web W was apply | coated in a 2nd application | coating process, the fragrance | flavor 26 has influence with respect to the combustion inhibitor 6. Never give. That is, since the combustion inhibitor 6 is water-soluble, it is possible to prevent the combustion inhibitor 6 from being dissolved by the fragrance 26. In addition, when a powdery fragrance | flavor is used as the fragrance | flavor 26, you may apply | coat to the same surface as the surface where the combustion inhibitor 6 was apply | coated.

Specifically, in the application of the fragrance, the second application device 5 is similar to the first application device 3 in that the fragrance 26 supplied from the press roll 9 and the gravure roll 10 and further from the nozzle 11 is the gravure roll 10. And a furnisher roll 12 that is in rolling contact with the gravure roll 10. The fragrance 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 fragrance | flavor is apply | coated indirectly via the gravure roll 10, a fragrance | flavor can be efficiently apply | coated using the conveyance roll for conveying the web W. FIG. When the fragrance 26 is applied by the gravure roll 10, the excess fragrance 26 is scraped off by the doctor blade 18 and removed from the gravure roll 10. The removed fragrance 26 is collected by a collection chute 19 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).

When manufacturing cigarette wrapping paper using the manufacturing machine 1 as described above, the following steps are performed. 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 step, the web W passes through the first drying device 4 in the direction of arrow B. In the first drying device 4, the web W is heated and dried. Through such a first drying step, the web W travels along the traveling path 2 in the direction of arrow C and enters the second coating step. In the second application step, the fragrance 26 is applied to the web W using the second application device 5.

Thus, the manufacturing method of the cigarette paper based on this invention performs a coating process using the 2nd coating device 5 with respect to the web W which passed the 1st drying apparatus 4 for performing a drying process, and a fragrance | flavor 26 is applied. That is, the application of the fragrance 26 to the web W is performed after the first drying step. Therefore, it is possible to prevent the fragrance 26 applied to the web W from being volatilized in the first drying process. By using such a manufacturing machine 1 or a manufacturing method, since the fragrance | flavor is not volatilized by the 1st drying apparatus 4, whatever fragrance | flavor 26 is used in the future, it can respond to it.

The fragrance applied in the second application step, that is, the fragrance 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 fragrance | flavor from the tank 14 to the 2nd coating device 5 is arrange | positioned. The remaining amount of the fragrance in the tank, that is, the consumption 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 may be provided with a function of monitoring the amount of the fragrance applied to the web W per unit area, and the fragrance may be selectively applied to the entire surface or a partial region of the web W using this function. In this case, for example, the amount of the fragrance 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 21, for example. If this actuator 21 is connected to the control device 16, the application amount of the fragrance 26 can be changed using the control device. In addition, although the example which applied the fragrance | flavor 26 to the whole surface of web W was shown in FIG. 3, it is also possible to apply this to arbitrary predetermined positions (for example, on the back surface of the location where the combustion inhibitor 6 was applied) Do not apply fragrance 26). Further, the fragrance 26 to be applied can be shaded using the control device 16.

In the second coating step, the web W further travels in the direction of arrow D along the travel path 2 and travels toward the second drying device 17. The second drying device 17 has a drying unit 20. In the second drying device 17, first, the 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.

The heating temperature in the second drying process using the second drying device 17 is lower than the heating temperature in the first drying process. This is based on the fact that the heating temperature in the first drying step is a temperature at which the fragrance is volatilized, and the heating temperature in the second drying step is a temperature at which the fragrance is not volatilized. That is, in the first drying step, the web W coated with the combustion inhibitor is dried, so that the heating temperature is so high that the fragrance is evaporated. On the other hand, since the 2nd drying process is for extending the wrinkles of the web W after apply | coating a fragrance | flavor, for example, the heating temperature is a low temperature at which a fragrance | flavor does not volatilize. Therefore, a 2nd drying process can be performed with respect to the web W, without volatilizing a fragrance | flavor. Specifically, for example, the heating temperature in the first drying step is 130 ° C., and the heating temperature in the second drying step is 85 ° C.

In the present invention, the amount of heat for drying the water applied to the web W in the second drying step is considerably larger than the amount of heat for drying the web W after applying the combustion inhibitor in the first drying step. It was made with a focus on smallness. Therefore, the aqueous solution containing a fragrance | flavor is provided to the web W and the volatilization of the fragrance | flavor by heat is prevented.

On the other hand, the web W that has undergone the second drying 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. Is done. 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.
