- FIG. 1 is a schematic configuration diagram of a rolled paper inspection device according to the present invention.
- P is a wrapper used for the production of cigarettes on one side of which a low-flammability substance is applied or affixed in a stripe form as a predetermined substance.
- the roll P is wound around a reel and rewound by a feeding roller.
- the wrapping paper P rewound by the feed-out roller is conveyed so as to be in contact with the inspection surface 10a of the wrapping paper inspection unit 10.
- the wrapping paper P is formed by applying or affixing a band Pe to which a low-flammability substance is applied or affixed in a stripe pattern at a constant pitch. That is, the wrapping paper P has a surface state in which the band parts Pe and the base parts Pi are alternately arranged.
- a feature of the present invention is that when a roll of paper P conveyed in contact with the inspection surface 10a of the roll paper inspection unit 10 is sucked from a suction unit 11 described later, the suction pressure of the suction unit 11 is reduced. The point is to detect the change and determine the quality of the low fire spread material applied to the wrapping paper P.
- the roll paper inspection apparatus according to the present invention has a ventilation resistance in the region of the base cigarette paper (base portion P i) of the roll P and the region (band portion P e) to which the low fire spread material is applied or affixed. The focus was on the differences.
- the inspection surface 10a of the wrapping paper inspection unit 10 has a width that is slightly narrower and slightly shorter than the area of the low-flammability substance applied or affixed to the long wrapping paper P.
- a cavity 12 having the shape of is formed below the inspection surface 10a.
- a suction pipe 13 is connected to the cavity 12. Therefore, the cavity 12 plays a role of sucking the wrapping paper P by the suction pump 14a.
- a suction pipe 13 provided between the cavity 12 and the suction pump 14a has a pressure reducing valve 15 for reducing the suction pressure of the suction pump 14a to an appropriate pressure.
- suction pump 14 Air that absorbs fluctuations in suction pressure of a A tank 16 and a flow control valve 17 for adjusting the suction pressure are connected in series.
- a pressure sensor 18 is attached to the suction pipe 13 so as to measure the pressure inside the suction pipe 13.
- the pressure level of the suction pipe 13 detected by the pressure sensor 18 is converted into an electric signal and output.
- the pressure-level signal (pressure signal) converted into the electric signal is supplied to a band-pass filter (BPF) 19 for removing unnecessary components contained in the signal, which will be described in detail later.
- BPF band-pass filter
- the band pass filter 19 serves to remove the fluctuation of suction pressure due to the dispersion of minute holes formed in the wrapping paper P, in other words, the noise component included in the pressure signal output from the pressure sensor 18. I am carrying it. It is desirable that the pass band of the band-pass filter 19 be about [30 Hz to 700 Hz].
- the pressure signal from which unnecessary components (noise) have been removed is applied to a wave-forming section 20 which uses a predetermined level as a threshold value to discriminate between a band Pe and a paper roll Pi coated or affixed with a low-flammability material. Given. Then, the signal discriminated by the waveform shaping section 20 into the band section Pe and the wrapping section P i is given to a determination section 21 which determines the quality of the low fire spread material applied or affixed to the wrapping sheet P.
- the rotating drum 22 has a drive system for rewinding the wrapping paper P wound on a reel (not shown).
- the rotary drum 22 is provided with an encoder 23 that outputs a pulse signal synchronized with the rotation of the rotary drum 22.
- the encoder 23 plays a role of a speed sensor that outputs a pulse having a period proportional to the transport speed of the wrapping paper P.
- the pulse signal output from the encoder 23 is, for example,
- the judging unit 21 applies or coats the wrapping paper P based on the correlation between the signal discriminated by the waveform shaping unit 20 into the band unit Pe and the wrapping unit Pi and the pulse signal output from the rotating drum 22. Judge the quality of the attached low-burning substance.
- the wrapping paper P has a large number of micropores that cannot be seen with the naked eye. In other words, wrapping paper P does not completely block air. For this reason, although the wrapping paper P has airflow resistance, air can be transmitted through a large number of minute holes opened in the wrapping paper P. Therefore, after the suction portion 11 is brought into contact with one surface of the wrapping paper P i and then one surface of the wrapping paper is suctioned by the suction pump 14a, the other side of the wrapping paper P passes through many minute holes existing in the wrapping paper P. Air flows in.
- the band portion Pe is a region where the low fire spread material is applied or affixed to the wrapping paper P. That is, the micropores of the wrapping paper P are closed by the low fire spread material applied or affixed to the band portion Pe. Therefore, the band section Pe of the wrapping paper P has an increased airflow resistance with respect to the base section Pi.
- the suction amount of the band part Pe decreases in comparison with the wrapping part Pi. Therefore, the pressure in the suction pipe 13 varies depending on the band portion Pe and the base portion Pi of the wrapping paper P if the suction pump 14a maintains the suction pressure constant. In other words, in the area of the wrapping paper part Pi, the negative pressure in the suction pipe 13 becomes small (the absolute pressure is high). On the other hand, in the region of the band portion Pe, the negative pressure in the suction pipe 13 increases (the absolute pressure is low).
- FIG. 3 is a graph showing a change in a pressure signal in the suction pipe 13.
- This graph shows the change in the pressure signal in the suction pipe 13 detected by the pressure sensor 18 when the wrapping paper P is transported in contact with the wrapping paper inspection unit 10.
- the output voltage of the pressure sensor 18 becomes lower in the band Pe region. This is because the ventilation resistance of the band portion Pe increases. That is, the negative pressure in the suction pipe 13 increases (the absolute pressure decreases).
- the output voltage of the pressure sensor 18 in the region of the wrapping portion Pi is high. This is because the ventilation resistance of the base portion Pi is smaller than that of the band portion Pe. That is, the negative pressure in the suction pipe 13 becomes smaller (the absolute pressure becomes higher).
- the wrapping paper P does not have a uniform ventilation resistance over the entire length.
- the output signal output from the pressure sensor 18 includes the airflow resistance of the base part Pi. Changes in pressure other than changes in resistance and changes in airflow resistance in band Pe may be included.
- the wrapping paper P has many fine holes. Therefore, the noise component affected by the fine holes in the wrapping paper P is superimposed on the pressure signal output by the pressure sensor 18. Therefore, the voltage level of the pressure signal output from the pressure sensor 18 fluctuates greatly. That is, the voltage level of the output signal output by the pressure sensor 18 fluctuates greatly as it is, and it is difficult to separate the output signal into the area of the base Pi and the area of the band portion Pe.
- the fluctuation of the ventilation resistance appears as a DC component of the pressure signal or a very low frequency component of the pressure signal.
- the noise component generated by the minute holes of the wrapping paper P has a cycle component (high frequency component) shorter than the repetition cycle of the wrapping paper P i and the band P e.
- the output signal of the pressure sensor 18 includes a DC component, an extremely low frequency component, and a high frequency component as noise. For this reason, the output signal of the pressure sensor 18 is passed to a band-pass filter (BPF) 19 to remove noise components included in the output signal.
- BPF band-pass filter
- This detection voltage is applied to a comparator (not shown) provided in the waveform shaping section 20.
- the threshold value of the comparator is set to [0] V.
- the determination unit 21 determines a portion having a voltage higher than the threshold value as a wrapping portion (P i) and a portion having a voltage lower than the threshold value as a band portion (P e). By doing so, the determination unit 21 can discriminate the wrapping paper part Pi from the band part Pe. Specifically, in FIG. 5, when the voltage level of the pressure signal becomes equal to or lower than [0] V, the band portion Pe is shown.
- the rotating drum 22 of the drive system for rewinding the wrapping paper P has Drum 2 of 2
- An encoder 23 that outputs a pulse signal synchronized with the rotation is provided.

- a low fire spread material is applied or affixed in stripes at a predetermined pitch.
- the band portions Pe formed on the wrapping paper P are provided at a pitch of [30] mm.
- the wrapping paper P has an area of the band portion Pe to which the low fire spread material is applied or affixed when the pulse output from the encoder 23 is counted [300]. That is, the determination unit 21 can determine the area of the band portion Pe of the wrapping paper P by counting the pulses output by the encoder 23.
- the determination unit 21 matches the detection position of the band P e obtained from the output pulse of the encoder 23 with the detection signal of the band P e detected by the pressure sensor 18. Is determined.

- the determination unit 21 when the detection position of the band portion Pe does not match the detection signal detected by the pressure sensor 18, the band portion Pe is not provided correctly on the wrapping paper P. Will be.
- the determination unit 21 clears the power of counting the output pulses of the encoder 23 by the presence signal of the band portion Pe output from the comparator (not shown) of the waveform shaping unit 20. Just fine. That is, if the band portions Pe are provided at a predetermined pitch on the wrapping paper P, the counter is reset. That is, as described above, if the band portions Pe are provided at a constant pitch on the wrapping paper P, the counter is reset. Therefore, the count-up signal (error notification signal) is not output. For example, assuming that band portions Pe are provided at a constant pitch on the wrapping paper P in the above-described wrapping paper P, the counter indicates that the number of pulses output by the encoder 23 becomes close to [300]. It will be reset.
- the determination unit 21 may output the abnormality notification signal when the pulse count exceeds [300 + ⁇ ] in consideration of the error [] of the pulse detection.
- the determination unit 21 may output an abnormality notification signal when the pulse count number is reset at or below [300—] in consideration of the error [] of the pulse detection. That is, the determination unit 21 determines that the number of pulse counts output from the encoder 23 in consideration of the measurement error is within the range of the number of pulses corresponding to the pitch of the low-burning material applied or affixed to the wrapping paper P. , It is determined that the band portion Pe is correctly formed.
