損なうという問題がある。In the above cigarette manufacturing process, the winding width of the wrapping paper fluctuates due to the physical properties of tobacco cutting, and the like.
When the thickness of the manufactured cigarette changes, the ventilation resistance and the air inflow ratio of the cigarette change, so that the smoke component (TN) of the cigarette changes, which adversely affects the taste. Also,
Also in the filter rod, when the thickness changes, the ventilation resistance and the air inflow ratio change, which adversely affects the taste of tobacco. Further, when the thickness of the cigarette is thick and the notch is loosely wound, there is a problem that the cut of the cigarette is easily deformed such as dropping or distortion of the notch from the cut edge, and the appearance quality of the product is impaired. .

In this apparatus, a laser is used, and the light receiving section is composed of a laser light receiver 1 corresponding to 105B, a laser projector 2 corresponding to the light projecting section 105A, a controller 3, and a measured value display device 4.
In FIG. 6, for the sake of simplicity, two light receivers 1 and two light transmitters 2 are arranged in FIG.
Are arranged one by one.

The output voltages of the controller 3 when the entire surface is shielded from light are obtained, and the relationship between the light-shielded portion of the light receiver 1 and the output voltage of the controller 3 is obtained from these voltages. For example, as shown in FIG. 7, the output voltage at the time of full light reception corresponding to the case where the diameter of the bar-shaped article is 0 mm is 5 V (point A), and the output voltage at the time of full light shielding corresponding to the case where the diameter of the bar-shaped article is 10 mm. Is set to 1 V (point B), a relationship between the area of the light-shielded portion of the light receiver 1 and the output voltage of the controller 3 can be obtained by drawing a straight line connecting the points AB. For example, when the output voltage at the time of measuring the diameter of a certain bar-shaped article is 3 V, the diameter of this bar-shaped article is measured as 5 mm from FIG. This calculation is performed in the controller 3.

差が生ずる。However, in the above conventional apparatus for measuring the thickness of a bar-shaped article, even if the output at the time of light reception on the entire surface is set to 5 V as an initial state in the controller, the surrounding atmosphere or the finely divided portion is not affected. If the lens of the laser projector or the laser receiver is contaminated with powder, the amount of light received by the receiver decreases, and the output voltage of the controller decreases. That is, as shown by the broken line in FIG. 7, the slope of the output voltage of the controller becomes small, and an error occurs in the display of the thickness of the bar-shaped article on the measurement display device.

In this case, a rod-like shape having a diameter of 5 mm is actually used. Even if it is an article, if the lens is dirty, the output voltage is 2.75 V, so that the diameter of this rod-shaped article is displayed as 5.52 mm, and between the measured value and the displayed value, 5.52mm-5m
An error of m = 0.52 mm will occur.
