The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are used for the same or similar components throughout the specification. In the case of publicly known technologies, a detailed description thereof will be omitted.

In this specification, when a part is referred to as "including " an element, it is to be understood that it may include other elements as well, without departing from the other elements unless specifically stated otherwise. Also, the terms "part," " module, "and the like, which are described in the specification, refer to a unit for processing at least one function or operation, and may be implemented by hardware or software or a combination of hardware and software.

1 is a cross-sectional view schematically showing an apparatus for manufacturing a low-fogging cigarette paper according to an embodiment of the present invention. Referring to Fig. 1, an apparatus for manufacturing a low- The cigarette paper 19 in the form of a roll is fed to the coating unit through the rollers 910,

The coating unit 100 is a unit for applying the coating composition 17 to the cigarette paper 19. For example, the coating unit 100 includes a flat roller 110 and a concave roller 120. The coating composition 17 is conveyed to the flat roller 110 by rotation of the concave roller 120 and the coating composition 17 is coated on the cigarette paper 19 by the flat roller 110 and the coating composition 17 The cigarette paper 19 with the low ignition potential applied thereto is moved through the roller 930. The coating unit 100 may include a supply member 140 in which the coating composition 17 is contained. Referring to FIG. 1, the supply member 140 may supply the coating composition 17 to the lower portion of the concave roller 120. The supply member 140 may supply the coating composition 17 to the upper portion where the concave roller 120 and the flat roller 110 meet.

The pyrophoric cigarette paper 19 coated with the coating composition 17 that has passed through the coating unit 100 passes through a drying unit 210, 220 which dries the coating portion 18. For example, the drying units 210 and 220 may be a heating bar, a near infrared lamp, or the like. One or more drying units may be used.

The low-firing cigarette paper 19 that has passed through the drying units 210, 220 passes through an air moving unit 300. The air transfer unit 300 includes an inlet 311 through which air is injected, an outlet 319 through which air is injected, and an air moving body portion 310. The air conveying unit 300 can reduce damage to the coated portion 18 of the low-ignitability cigarette paper 19 that is not completely dried by transferring the low-ignitability cigarette paper 19 by changing direction using air, It is possible to prevent a conveyance failure due to the conveyance.

Air may be compressed air. For example, the pressure of the compressed air can be from about 3 bar to about 6 bar. By controlling the amount of compressed air, the height at which the low-ignitability cigarette paper 19 floats can be appropriately adjusted. The air can be dispersed in a direction substantially perpendicular to the coating portion 18. The discharge port 319 is located on the curved surface of the air transfer body portion.

The low-ignitability cigarette paper 19 that has passed through the air transfer unit 300 passes through the cooling units 230 and 240. The cooling units 230 and 240 lower the temperature of the low-ignitability cigarette paper 19 raised by the drying units 210 and 220. For example, the cooling units 230 and 240 may be cooling bars supplied with a material such as cooling water. One or more cooling units 230 and 240 may be used.

The low-ignitability cigarette paper 19 that has passed through the cooling units 230, 240 passes through the air transfer unit 400. The air conveying unit 400 includes an inlet 411, an outlet 419 and an air conveying body portion 410. The description of the air conveying unit 300 described above can be equally applied.

The low-ignitability cigarette paper 19 that has passed through the air transfer unit 400 is supplied to the cigarette manufacturing apparatus including the low-ignitability cigarette paper through the roller 940.

An apparatus for manufacturing a low-ignition cigarette paper can be implemented in an on-line manner by being mounted inside a cigarette manufacturing apparatus, and can be implemented in an off-line form by being mounted outside the cigarette manufacturing apparatus. The cigarette paper of the thus-manufactured cigarette 1 includes a plurality of coating portions 18 coated with a coating composition made of a combustible material, for example, as shown in FIG. 3 (b). Although the coating portion 18 shown in FIG. 3 (b) is shown in the form of a band, it may have various shapes.

Meanwhile, the apparatus for producing a low-fogging cigarette paper to which the coating position correcting apparatus according to an embodiment of the present invention is applied is not limited to the above-described apparatus for producing a low-fogging cigarette paper.

Hereinafter, a coating position correcting apparatus according to an embodiment of the present invention will be described as an example of an apparatus for manufacturing a low-ignition cigarette paper described with reference to FIG. 2 is a block diagram of a coating position correcting apparatus according to an embodiment of the present invention, in which the coating unit 100 is moved in response to a coating position error.

2, a coating position correcting apparatus according to an embodiment of the present invention includes a coating position detecting sensor 101, a coating position locating unit 102, an error detecting unit 103, an error value obtaining unit 104, A position adjusting unit 105, a coating position correcting apparatus 106, and a moving apparatus 107. [

The coating position detection sensor 101 is a sensor for detecting the position of the coating portion 18 in the cigarette paper or the position of the coating portion 18 in the process line after the coating portion 18 is formed on the cigarette paper by the coating unit 100 And is installed in any one position. Although the coating position detecting sensor 101 is shown in Fig. 2 as being located near the roller 940, it is ideally located near a cutout (not shown) for cutting the low-fogging cigarette paper. This is because the coating position detecting sensor 101 is provided in the vicinity of the cutting portion to reduce the influence of positional deviation due to paper stretching.

As the coating position detection sensor 101, for example, a contrast sensor or the like is used. The contrast sensor irradiates the cigarette paper with a laser beam and converts the reflected light into an analog current and outputs it. At this time, the output current of the sensor changes depending on the contrast and reflectivity of the surface of the cigarette paper on which the laser beam hits. For example, as shown in FIG. 3 (a), the portion where the coating is not performed has a high current value, and the coated portion has a low current value. FIG. 3 is a diagram showing a band position error detection method according to an embodiment of the present invention, in which the output of the coating position detection sensor 101 is amplified and inverted.

The coating position determination unit 102 receives and amplifies an output of the coating position detection sensor 101, that is, an analog current, converts the analog current into a square wave at an appropriate threshold level, As shown in FIG. The coating position determination unit 102 compares the specific inter-band distances in the repeated arrangement of the coated bands to detect the position of the specific pattern, and provides information on the determined coating position to the error detection unit 103. For example, , And the coating position determination unit 102 determines the position of the coating position determination unit 102 It is possible to detect a position where a 30 mm band distance is generated in an arrangement in which an equal band is repeated infinitely.

The error detector 103 stores information on the normal coating position and compares the information on the coating position received from the coating position detector 102 with information on the normal coating position to detect an error in the coating position.

Here, the information on the coating position provided by the coating position locating unit 102 may be the output of the coating position detecting sensor 101 as shown in FIG. 3A or the coating position detecting sensor 101 as shown in FIG. (Hereinafter referred to as " detected square wave ") corresponding to the output of the position detection sensor 101. [ Or information on the coating position may be represented by various types of deformation information such as time and phase information at the time of occurrence.

If the information on the coating position used in the error detection unit 103 is the output of the coating position detection sensor 101, the coating position determination unit 102 may be omitted from the configuration. This can be used for band distances of the same distance.

The information on the normal coating position corresponds to the information on the coating position provided by the coating position determination unit 102. For example, the information on the normal coating position is information on the coating position provided by the coating position determination unit 102 (Hereinafter referred to as " reference square wave ") corresponding to the detected rectangular wave C2 when the information is the detected rectangular wave C2.

The error detector 103 calculates the difference angle by comparing the reference angle with the mechanical angle captured at the rising time at which the reference square wave is generated.

The error value determination unit 104 converts the difference angle calculated by the error detection unit 103 into the correction distance L. [

The correction position adjustment unit 105 corrects the correction distance L provided by the error value determination unit 104 based on the correction speed (correction speed) and the rotation speed RPM And the correction position adjustment unit 105 outputs a drive signal for shifting the correction unit by a correction value in units of length of the coating unit 100.

The coating position correcting apparatus 106 generates a driving force in accordance with the driving signal of the correction position adjusting unit 105. The moving device 107 operates in conjunction with the operation of the actuator 106 and is configured such that the coating unit 100 (or the flat roller 110) can be moved by operation and provided by the coating position correcting device 106 Moves by the correction value of the length unit according to one driving force, and moves the coating unit 100 by the correction value of the length unit. At this time, the correction value has a value of "-" or a value of "+", and moves the coating unit 100 to the roller 920 side or the roller 930 side according to the value of "-" or "+".

Here, the moving device 107 may be disposed under the coating unit 100 to support the fixing and movement of the coating unit 100, or a separate device for supporting the fixing and movement of the coating unit 100 may be provided. Move the device.

The coating position correcting apparatus according to an embodiment of the present invention includes an output of the coating position locating unit 102, an output of the error detecting unit 103, an output of the error value determining unit 104, (Not shown) that allows the user to visually confirm the operation state of the display device.

Hereinafter, a coating position correction method will be described with reference to FIG. 4 is a flowchart illustrating a method of correcting a coating position according to an embodiment of the present invention.

Referring to FIG. 4, the coating position detecting sensor 101 irradiates a laser beam to the low-fogging cigarette paper being transported (S401), receives the reflected light, and transmits an analog current value corresponding to the received reflected light to the coating position locating unit 102 (S402).

The coating position determination unit 102 determines a point at which the received analog current value indicates a current value that is equal to or greater than a predetermined value as a coating position and generates a detection rectangular wave C2 corresponding to the detected coating position and provides the detected rectangular wave C2 to the error detection unit 103 (S403). The error detector 103 compares the received detected square wave C2 with a predetermined reference square wave C1 or compares the measured mechanical angle and the reference angle with the detected rectangular wave C2 at step S404, , And determines a position error (i.e., time error) in the detected rectangular wave C2 (S405).

When a position error is generated by the error detection unit 103, the error value determination unit 104 grasps the distance error L corresponding to the position error and provides it to the correction position adjustment unit 105 (S406). The correction position adjustment unit 105 calculates a correction length corresponding to the time error L, that is, a correction value in the unit of length (S407), and adjusts the coating position correction so as to move the coating unit 100 corresponding to the correction length And controls the operation of the device 106 (S408).

When the coating unit 100 moves by the correction length, the position coated on the cigarette paper is changed to the normal position, so that the error detecting unit 103 does not detect the coating position error. On the other hand, if the coating position information corresponding to the set coating position is not detected, the error detecting unit 103 determines that the coating corresponding to the coating position is not performed, and informs the user of the coating position or stops the manufacturing apparatus

Hereinafter, a coating position correcting apparatus according to an embodiment of the present invention will be described with reference to FIG. FIG. 5 is a block diagram of a coating position correcting apparatus according to another embodiment of the present invention, in which the synchronizing angle of the coating unit 100 is adjusted corresponding to a coating position error. Hereinafter, the same reference numerals are assigned to the same components as those of the above-described embodiment.

5, a coating position correcting apparatus according to an embodiment of the present invention includes a coating position detecting sensor 101, a coating position locating unit 102, an error detecting unit 103, a correction speed calculating unit 104a, A speed calculator 105a, a driver 106a, and a motor 107a.

The coating position detecting unit 101 detects the coating position of the coating portion 18 on the cigarette paper and the coating position detecting portion 102 detects the coating position of the coating portion 18 on the cigarette paper, And provides the information on the coating position to the error detection unit 103. [0051] The error detector 103 stores information on the normal coating position and compares the information on the coating position received from the coating position detector 102 with information on the normal coating position to detect an error in the coating position.

The information on the normal coating position corresponds to the information on the coating position provided by the coating position determination unit 102. For example, the information on the normal coating position is information on the coating position provided by the coating position determination unit 102 The information may be the mechanical angle (the angle of the rotary encoder installed on the machine axis) captured at the time of generation of the detection square wave C2.

The error detecting unit 103 compares the detected specific band interval with the reference angle, and determines that there is an error if there is an error.

Determining an error means the difference between the position at which the reference pattern is generated and the set reference angle.

Then, the correction speed calculator 104a converts the angular error into a speed value according to the set conversion function (or conversion table, etc.). The speed thus obtained is the correction speed.

The driving speed calculating section 105a receives the speed information of the main shaft connected to the concave roller 120 of the coating unit 100 and receives the correcting speed from the correcting speed calculating section 104a and corrects the correcting speed and the speed of the main shaft And the driving speed is calculated. For example, when the speed information of the main shaft is measured by a rotary encoder (not shown), the driving speed calculating section 105a receives the speed of the main shaft from the rotary encoder.

The driver 106a receives the driving speed from the driving speed calculating unit 105a, calculates a driving signal corresponding to the received driving speed, and drives the motor 107a with the calculated driving signal.

The driver 106a receives the driving speed from the driving speed calculating unit 105a, generates a rotational power corresponding to the received driving speed, and drives the motor 107a.

The motor 107a is connected to the two rollers 110 and 120 (hereinafter, referred to as 'coating roller') of the coating unit 100 via a main shaft and rotates at a rotational speed .

The rotation speed of the coating rollers 110 and 120 becomes faster or slower depending on the rotation speed applied from the motor 107a. Therefore, the coating rollers 110 and 120 to which the rotation speed added by the correction speed is applied are accelerated or slowed down by the correction speed, thereby changing the synchronization angle and correcting the angular error.

Hereinafter, a coating position correction method according to another embodiment of the present invention will be described with reference to FIG. 6 is a flowchart illustrating a method of correcting a coating position according to another embodiment of the present invention.

Referring to FIG. 6, steps S601 to S605 are the same as those of steps S401 to S405 described above with reference to FIG. 4, and a detailed description thereof will be omitted.

When the error detecting unit 103 determines that the coating position is error, the correction speed calculating unit 104a calculates the error angle (S606), calculates the correction speed corresponding to the error angle, and provides the correction speed to the drive speed calculating unit 105a (S607). Then, the driving speed calculating unit 105a calculates the driving speed obtained by adding the correction speed at the main axis speed of the coating rollers 100 and 120 which are currently being driven, and provides the driving speed to the driver 106a (S608).

The driver 106a generates a rotational force corresponding to the summed driving speed and provides the rotational force to the motor 107a and the motor 107a rotates the shaft of the coating roll (S609) And rotates at a correction speed added to the shaft rotation (S610).

In view of the rotation of the coating rollers 110 and 120 reflecting the correction speed, when the coating position error is negative (i.e., when the detection position is later than the reference position and the error angle indicates a negative value), the correction speed is reflected The rotation speed of the coating rollers 110 and 120 is increased by the magnitude of the error angle. When the coating position error is (+), that is, when the detection position is faster than the reference position and the error angle indicates a (+) value, the coating rollers 110 and 120, It slows down.

Hereinafter, a coating position correcting apparatus according to another embodiment of the present invention will be described with reference to FIG. FIG. 7 is a block diagram of a coating position correcting apparatus according to another embodiment of the present invention, in which the synchronizing angle of the coating unit 100 is adjusted using a differential gear corresponding to a coating position error. Hereinafter, the same reference numerals are assigned to the same components as those of the above-described embodiment.

Referring to FIG. 7, a coating position correcting apparatus according to an embodiment of the present invention includes a coating position detecting sensor 101, a coating position locating unit 102, an error detecting unit 103, a correction speed calculating unit 104a, A driver 106b, a correction motor 107b, and a differential locker 108. [

The coating position detection unit 101 detects the coating position of the coating unit 18 in the cigarette paper and the coating position determination unit 102 grasps the coating position through the output of the coating position detection sensor 101, The controller 103 determines that the coating position is an error in the coating position, and the correction speed calculator 104a calculates the angular error and calculates the correction speed corresponding to the angular error.

The correction driver 106b generates a drive signal corresponding to the correction speed to drive the correction motor 107b and the wobble motor 107b provides the power (rotational force) corresponding to the correction speed to the differential locker 108 .

The differential synchronizer 108 is composed of at least one gear for rotating the main shaft and at least one gear rotated by the correcting motor 107b. When there is no coating position error, the differential synchronizer 108 rotates the concave roller 120 And when the coating position error occurs, the concave roller 120 is rotated at the rotational speed at which the rotation speed of the main shaft and the correction speed are added together.

The rotation speed of the concave roller 120 is adjusted by the rotational speed to which the correction speed is added, and compensation for the coating position error, that is, the angular error, is made accordingly.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It belongs to the scope.
