Abstract: A measuring device determines the outer circumferential length of a rod-like item at its wind-up section. The wind-up section includes a roll paper supply part that provides continuous roll paper to a constituent part of the rod-like item and a wind-up part that wraps the constituent part with the supplied roll paper to form the rod-like item. The roll paper supply part consists of a first measuring part that assesses the paper width in the width direction crossing the roll paper's longitudinal direction, a second measuring part that measures the overlap width of the part overlapped by the roll paper around the rod-like item, and a calculating part that computes the outer circumferential length based on the differential width obtained by subtracting the overlap width from the paper width.

Abstract: This measurement device calculates the outer circumferential length of a rod-shaped article in a transportation section using a camera and an image processing unit. The camera captures the end surface of the rod-shaped article, and the image processing unit processes the image to determine the length. The unit identifies the outer circumferential edge in the image, constructs an imaginary circle based on this edge, and draws straight lines through the circle's center. It identifies intersections where the lines meet the edge, measures distances between adjacent intersections, and sums these distances along the full circumference to calculate the outer circumferential length.

Abstract: A measuring device is provided for determining the outer circumference length of a rod-shaped article in a conveyance section. The device includes a camera that captures an image of the article's end surface and an image processing unit that processes the image to calculate the circumference. The unit identifies the outer edge of the end surface, generates a virtual circle based on the edge, and draws n straight lines through the circle's center. It identifies intersection points where each line intersects the outer edge and measures distances (d1, d2, . . . , dn) between intersections along each line. The virtual diameter is obtained by averaging these distances, and the outer circumference length is calculated by multiplying the virtual diameter by π.

Abstract: A filter manufacturing machine includes a forming device for forming filter tow into a hollow rod-shaped continuous filter body, a forming tube included in the forming device and having a tubular forming path through which the filter tow is passed while being brought together, a mandrel arranged in the forming tube and forming the tubular forming path in cooperation with the forming tube, and a heat treating section included in the forming tube and configured to heat the filter tow while the filter tow passes through the tubular forming path. The mandrel has a small-diameter portion located at the inlet of the forming tube, a large-diameter portion located at the outlet of the forming tube, and a diameter expansion portion located between the small- and large-diameter portions. The diameter expansion portion is located downstream of the heat treating section as viewed in the moving direction of the filter tow.

Abstract: An inspection device 50 for a filter inspects the filter, which is provided to a flavor inhalation article. The filter is provided with a mouthpiece end, a solid material, and a communication path that communicates with the solid material and opens to the mouthpiece end. The inspection device is provided with: an illumination for irradiating an inspection light onto the mouthpiece end in an irradiation direction that extends along the axial direction X; a camera for photographing the peripheral surface of the filter in a photographing direction that extends along the radial direction Y of the filter; an image processing unit for processing an image photographed by the camera and detecting a shadow of the solid material; and, an assessment unit for assessing the presence or absence and the quality of the solid material 12 on the basis of the shadow detected by the image processing unit.
