The SCOPE of the INVENTION

The present invention relates to a machine and method of production kabuliwala canvas, which gives cigarettes a property of the weak decay, and to a method of manufacturing laboriosa wrapping paper used for cigarettes.

The LEVEL of TECHNOLOGY

Recently has become popular laboriosa wrapping paper for cigarettes. This laboriosa wrapping paper prevents the spread of fire to flammable materials, if a lit cigarette with this wrapping paper will fall on combustible material. Cigarette contains Smoking material such as shredded tobacco, and paper wrapping, which is wrapped Smoking material. This paper is laboriosa (for example, see Figure 2 of patent document 1).

More specifically, laboriosa wrapping paper disclosed in patent document 1 contains the paper and strips that are posted on the web in the longitudinal direction with predetermined intervals. These strips are formed by coating on the fabric fire retardant. Inhibitor of combustion being applied in the form of an aqueous solution. The canvas is coated with a fire retardant is dried in the drying apparatus for forming laboriosa wrapping paper.

After drying, the width of the wrapping paper is reduced by approximately 3-7% as a result of shrinkage. N the example, if the initial width of the wrapping paper was 1040 mm, the shrinkage of 3% this width will be 1010 mm, and shrinkage of 7% width will be 970 mm Dried cloth is cut into tapes of a width of 27 mm and wound into rolls of wrapping paper, each of which has a width of 27 mm, If the paper is dried with the magnitude of the shrinkage of 3%, you get 37 rolls of a width of 27 mm, and if the shrinkage is 7%, you will receive 35 rolls. Thus, different value of shrinkage gives a different number of rolls of wrapping paper, which leads to destabilization of production. In addition, since the combustion inhibitor is applied to the canvas in a fixed amount and at regular intervals, if the number of rolls from one canvas to another will be different, the number of applied fire retardant will also be varies from roll to roll. It is not possible to make wrapping paper with a stable quality.

In order to maintain a constant shrinkage control the temperature of the drying and tension. However, it is necessary to change the temperature setpoint, depending on the time of year and depending on the time of day. Maintaining a constant shrinkage is a tedious task.

The PREFERRED embodiment of the INVENTION

In Fig. 1 shows a schematic view in plan. Machine for the production of kabuliwala cloth of the present invention is part of a machine 1 for producing laboriosa wrapping paper. Machine 1 contains the path 2, the applicator 3, the drying device 4, the smoothing device 5 and the device 6 for the formation of the slits. Machine for the production of kabuliwala p the pilot formed by the applicator 3, the drying device 4 and the controller 10, which will be described below. The applicator 3, the drying device 4, the smoothing device 5 and the device 6 for the formation of the slots are located on route 2. Cloth W is made of paper and unwound from a source roll (not shown) to move along the path 2 in the direction shown by the arrow T. the Width of the paper is first measured by the sensor 34. Canvas W then passes through the applicator 3. The applicator 3 is partially causes the inhibitor 7 burning on canvas W. Inhibitor 7 combustion is applied to many provisions on canvas W, spaced in the longitudinal direction of the cloth W, and passes in the direction of the width W. the Canvas W coated with a fire retardant passes through a drying device 4. A drying device 4 is equipped with a number of the drying furnace (not shown). Canvas W passing through the drying furnace for drying. After drying, the cloth W is smoothed in the smoothing device 5. Then in the canvas W make slits in the device 6 for the formation of the slit and wound into rolls 8 wrapping paper.

The sensor 9 serving as a detector, located near the exit from the drying device 4. The sensor 9 measures the width W which has passed through the drying device 4. The sensor 9 is connected to the controller 10. The controller 10 adjusts the parameter of the drying and connected with suchilin the m device 4. In summary, the controller 10 based on the measurement results of the sensor 9 adjusts the parameter in a drying device 4 so that the width W was in the acceptable range. You can make wrapping paper 8 stable quality by drying with the required parameter in accordance with the width of the dried cloth W.

More specifically, the controller 10 includes a computing section 11, the determining section 12 and control section 13. The computing section 11 receives the results of the measurement of a parameter indicating the width (actual width W) from sensors 34 and 9, and finds the coefficient of shrinkage of the dried leaf W. For this purpose, the sensors 34 and 9 are directly connected to the computing section 11. The determining section 12 determines whether the shrinkage of the dried leaf W in the acceptable range. Predefined tolerance shrinkage respectively change depending on the type produced wrapping paper or different other conditions. When the shrinkage of the cloth W is outside acceptable limits, the control section 13 changes the setting of drying in the drying device 4. The shrinkage of the dried cloth W is a consequence of option of drying, so you can make the cloth W with the constant shrinkage. As described above, the condition of the cloth W is part detected by determining the shrinkage of the dried leaf W, and based on this state change parameter drying. Consequently, it is possible to produce wrapping paper 8 is more stable quality. Since the shrinkage ratio remains constant from each source coil can be obtained the same number of rolls of wrapping paper. In addition, if you lock this function, the number of plotted inhibitor 7 combustion respectively becomes uniform for each roll that allows wrapping paper 8 stable quality.

In the present description parameter drying, which regulates the controller 10 is drying temperature. Drying temperature is the temperature effect which is subjected to the cloth W. the Cloth W with the required shrinkage ratio can be obtained simply by changing the temperature setting. More specifically, the drying temperature is the oven temperature in the drying device 4, which passes through the cloth W, or the temperature of hot air supplied into the drying furnace. The temperature in the furnace is changed in various ways, including the air supply to the furnace and the heating furnace heater, etc. Temperature change by changing the temperature of hot air supplied into the drying furnace. Control section 13 is connected with indicators 14 temperature, placed in drying ovens. To adjust avci hot air temperature regulating section 13 is connected to the device 15 with hot air, located in the drying device 4, thereby adjusting the temperature at the entrance. As described above, since the adjustable temperature is the temperature in the furnace or the temperature of hot air, using a simple method you can confidently make cloth W with the desired shrinkage. Preferably, the temperature in the drying furnace, below the direction of travel set lower than that in the furnace above the moving direction, and regulate the temperature in the furnace, below the direction of movement, which affects the shrinkage during drying. For example, the temperature in the furnace above the direction of movement, set on level 130aboutC, and the temperature in the furnace, below the direction of movement, set at level 80aboutC. Can provide a quick response when regulating section 13 requires modification of the parameter of drying, since the temperature in the furnace, below the direction of movement of the 100aboutC or lower. Therefore, you can quickly set the desired temperature.

The sensor 9 is a CCD (CCD) sensor with a laser beam. In this case, the sensor 9 is located on each side (width) of the fabric W is moved along the path 2. This CCD sensor with a laser beam is a laser displacement sensor. CCD (CCD device to charge the howling link) serves as a light receiver. CCD determines the amount of light for each pixel and is able to accurately determine the maximum amount of light. Thus, one can accurately measure the width W.

Also near the exit from the drying device 4 has a meter 16 humidity, which works as a sensor. The meter 16 humidity measures the moisture content in the web W passing through the drying device 4. The meter 16 humidity connected with the computing section 11 of the controller 10. The computing section 11 is configured to determine the percentage of moisture in the cloth W. the Determining section 12 is configured to determine if the percentage of moisture in the acceptable range. When the percentage of moisture within the permissible bounds regulating section 13 changes the setting of drying in the drying device 4 so that the moisture content of the cloth W is included in the permissible limits. In this way, the moisture content in the dried cloth W is measured by the meter 16 and humidity parameter drying regulated by the controller 10, depending on the moisture content. Thus, the parameter drying properly adjusted so that the dried cloth W had given shrinkage. In the result, it is possible to produce wrapping paper 8 stable quality. The regulation, based on the sensor 9 andregulation, based on the meter 16 humidity, can be done simultaneously or sequentially.

As follows from Fig. 2, the applicator 3 has the first tank 18, a second tank 19, the feed path 20, causing the device 21, the volume measuring device 22 and the regulating device 23. The first and second tanks are communicated with each other and contain the inhibitor 7 burning. The feed path 20 is used to supply inhibitor 7 combustion from the first tank 18 for causing the device 21. Therefore, the input end of the feed path 20 is located inside the first tank 18 and the inhibitor 7 combustion from the first tank 18 is fed by a pump 24 to the output end in the direction shown by the arrow R. Damaging the device 21 causes the inhibitor 7 combustion supplied through the path 20, directly on canvas W.

Next is a detailed description of the method of application using a dealing device 21.

Canvas W moves along path 2 (Fig. 1). At this time, the cloth W is unwound from a feed roll and stretched, getting on the receiving roll. Causing the device 21 contains bumagoopornogo roller 25 and the shaft 26 gravure printing. Bumagoopornogo roller 25 and the shaft 26 gravure printing pass across the way 2 move or across the web W. They are made to rotate in the opposite direction relative to each other. On the peripheral surface of the shaft 26 g is obakoy print has a corrugated pattern (not shown). The grooves of this figure are with uniform intervals in the direction of the circumference of the shaft 26 gravure printing so that the inhibitor 7 combustion is applied to many places with oriented in the longitudinal direction intervals, passes across the web in the direction of the width.

With the outer peripheral surface of the shaft 26 gravure printing contact with the possibility of rotation of the rolling platen 27. Over rolling roller 27 is located the nozzle 28. The nozzle 28 is connected with the first reservoir 18 through the feed path 20. During operation of the pump 24 of the feeding path 20 delivers an inhibitor of combustion from the first tank 18 through the feed path 20 to the nozzle 28. The nozzle 28 delivers an inhibitor of combustion into the space between the engraved roller and a pressure roller 27.

Above the shaft 26 gravure printing is the doctor blade 29. The doctor blade 29 has an end being in sliding contact with the outer peripheral surface of the shaft 26 gravure printing. Underneath the shaft 26 gravure printing and doctor blade 29 is the pallet 30. The pallet is held before the first tank 18. Inhibitor 7 burning, do not fall on the cloth W is returned to the first tank 18 and is sent back to the pump 24 in the feed path 20.

The doctor blade 29 scrapes excess inhibitor burning with the outer peripheral surface of the shaft 26 gravure printing. Remote inhibitor combustion is returned to the first choice of the reservoir 18 on the pallet 30 (in the direction shown by the arrow Q in Fig. 2). When the car 1 is running, the fire retardant in the first reservoir 18 is in constant fluid circulating between the position in which it is applied to the fabric W (shaft 26 gravure printing), and the first tank 18.

The first reservoir 18 is placed on the scale 31. The weight of the first tank 18, or the number of inhibitor 7 combustion, measured by the meter 22. The meter 22 number equipped, for example, a display. On the basis of the measurement results, the display shows the remaining amount, or quantity consumed of the fire retardant in the first tank 18. The measurement result is transmitted to the regulating device 23. The regulating device 23 regulates the flow of fire retardant, opening/closing valve 33 in the connecting pipe 32 between the first and second tanks 18 and 19 so that in the first reservoir 18 is always a constant amount of inhibitor. The pipe between the first and second tanks 18 and 19 is heated to a constant temperature.

Inhibitor 7 combustion has a constant temperature and the amount of inhibitor 7 combustion in the first reservoir 18 is kept constant, therefore, the inhibitor 7 combustion applied to the fabric W has a constant viscosity. So the quality of the cloth W, passing through the drying device 4, you can keep the rent is affordable, that allows you to maintain a constant quality of the dried cloth W. the Change of the shrinkage factor, therefore, is invoked only by the influence of the drying device 4, which means that the shrinkage of the cloth W can be accurately maintained as a constant, simply by adjusting the parameter drying. The residual quantity of the inhibitor 7 combustion in the first tank 18 can be measured by measuring the level of liquid in the tank or in any other way, provided that the viscosity of the inhibitor 7 combustion remains constant.

Next with reference to Fig. 3 is a description of how production laboriosa wrapping paper using the machine 1 according to the present invention. The reference position in the following description, identical to the positions of Fig. 1 and 2.

When the machine is switched on 1 canvas W unwound from the source roll and moves along path 2 move, and before applying the inhibitor 7 burning on the paper web W width of the paper web W is measured (step S1). After the cloth W will be included in the applicator 3, the meter 22 measures to determine whether the number of inhibitor 7 combustion in the first tank 18 to a specified value (step S2). If the number is equal to the specified value, the inhibitor 7 combustion is applied directly to the canvas W (step S3). On the cloth W is continuously applied inhibitor 7 burning, and it re asaeda on the way 2 move. When applying inhibitor 7 burning on canvas W number of inhibitor 7 combustion in the first reservoir 18 is reduced. The amount of inhibitor 7 combustion in the first tank 18 reaches a specified value or becomes less than a specified value. To maintain a constant amount of inhibitor 7 combustion is supplied from the second tank 19 in the first tank 18 (step S4). The phase deposition inhibitor 7 burning on canvas W perform, tracking the number of inhibitor 7 combustion in the first tank 18. In other words, when the cloth W is applied inhibitor 7 combustion in the applicator 3, the steps S2-S4 are repeated.

Cloth W is subjected to a stage of drying in the drying device 4 (step S5), after drying phase of width W extending from the drying device 4, is measured (step S6). On the basis of the measured width by calculation processing section 11 are shrinkage in the drying cloth W (step S7). Then, the determining section 12 determines whether this shrinkage ratio within the acceptable range (step S8). If the shrinkage ratio is within the acceptable range, the step of drying continues. If the shrinkage factor has gone beyond permissible limits, the option of drying change so that the shrinkage factor is back within tolerance (step S9), and then continue the process of drying. Regulation, including the steps S6 and S9, repeat for this is PA drying, i.e. until then, until there is not cloth W.

When not cloth W is the stage of drying in the drying device 4 finish. For smoothing out wrinkles affected by the shrinkage of the cloth W to perform the step of smoothing by the smoothing device 5 (step S10). The device 6 for the formation of the slits executing a step of forming slits, thereby forming a slot of a given width in the web W and forming rolls of wrapping paper 8 (step S11).
